Model XQ140/12A HYDRAULIC SUCKER ROD TONG OPERATION MANUAL

1.Summary Model XQ140/12A hydraulic power tong is a mouth opening power tong which can quickly make-up or break-out pipe strings in well service. It is used in making-up or breaking-out tubing, small drilling pipe and small casing with diameters from 2 7/8″-51/2″ (73mm to 140mm). Compared with the same type of tongs by other tong makers, it features simple structure, convenient operation, reliable performance, long life, broad application range and large torque. It is widely used in onshore or offshore oilfields. It can reduce workload, improve work efficiency and the well service quality.

2.Structure Characteristics And Working Principle Hydraulic power tong consists of two main parts----master tong and backup tong. The backup tong clips coupling or joints, (It can also clip the pipe body by lengthening the front and back guide poles as required.) and the master tong clips pipe string, turns clockwise or counter-clockwise, in this way, it completes making-up or breaking-out operations. 2.1 Transmission System

Hydraulic power tong has four shifts to reduce speed, as shown in figure 1. Low Gear Engagement: Z2, Z1, Z3, Z5, Z6, Z7, Z11, Z12, Z13 Second Low Gear Engagement: Z2, Z1, Z3, Z5, Z10, Z11, Z12, Z13 Second High Gear Engagement: Z2, Z4, Z6, Z7, Z11, Z12, Z13 High Gear Engagement: Z2, Z4, Z8, Z9, Z10, Z11, Z12, Z13

2.2.1 Clamping Mechanism (Fig.2, Fig.3)

The clamping mechanism adopts inner curved bilateral clamping mechanism. It consists of ramp plate, roller, roller axle, jaw plate, die seats, tong dies and jaw plate frame assembly. The jaw plate frame assembly is fixed in the inner side of the open gear. The spline on the board matches the spline on the connection plate of braking mechanism. When the transmission system starts to drive the open gear to turn, the jaw plate frame assembly doesn’t turn first at all under the braking force from the braking mechanism, the curved ramp plate turns together with the open gear, the roller on the jaw plate climbs along the curved surface of the ramp, moving jaw plate assembly towards the center, thus the preliminary clamping is achieved. As the torque increases and exceeds the braking moment, the open gear drives the spline connection plate, braking disc, jaw plate frame assembly and the jaw plate in the braking mechanism to turn together with the pipe string. The backup tong clamping mechanism is the same as that of the master tong. The hydraulic oil drives rack plunger to make reciprocating movement and also drives the duplex gear and the jaw plate frame to turn inside the main body of the backup tong, which drives the roller to climb, finally clips or looses the pipe string. 2.2.2 Braking Mechanism (Fig.2)

Jaw plate frame assembly must be braked to drive roller and ramp to move in opposite directions (i.e. climbing and resetting). The braking mechanism consists of braking plate, braking steel disc, spline connection board, upper and lower friction disc, adjusting screw, spring and lock nut. It can change braking moment by adjusting the compress force from the spring.

2.2.3 Reset Mechanism (Fig.3)

The initial working position of hydraulic power tong refers to the jaw plate frame and the open gear face the opening of the shell body of the master tong, the jaw plate frame of the back-up tong faces the opening of backup tong main body. The openings of master and backup tongs should be in alignment. After one making-up and breaking-out operation ends, operate the hand control valve in the opposite direction to return the hydraulic power tong to its initial working position, allowing the pipe string in or out through the tong opening smoothly. During making-up and breaking-out, reset knobs on the master and backup tongs should be in the same direction. 2.2.4 Centralizing Mechanism (Fig.2 and Fig.4)

The centralizing mechanism centralizes from up and down, inside and outside. It consists of roller support frame, centralizing roller, centralizing roller axle and roller, which are respectively installed on the shell body and the cover of the tong head. They match the open gear and the groove on the cover of the open gear to guarantee the open gear turns along the original axle central line to avoid deflection and axial running-out, thus the tong head is centralized.

4.Installing, Testing and Relative Requirement Installing procedures are as follows when hydraulic power tong is used on well site. 4.1Check Before Installation

●Check power tong damaged or not during transportation. If damaged, it should be repaired. ●Check the fastening parts loose or not, tighten any loose parts. ●Check jaw plate, die seats and dies complete or not. (Fig.5.1) 4.2Lifting

4.2.1Lifting operation at the drilling rig or work-over rig is shown as Fig.12. 4.2.2Connect hydraulic bucket to the suspension bar of master tong by bolts. 4.2.3Install a pulley on the mast, which can bear load of 4400bf or more. 4.2.4Lift hydraulic power tong by a soft steel wire of 1/2″ or bigger, put this wire through the pulley on the mast, one end connecting hydraulic bucket and the other end fixed at the mast. Make dies of backup tong directly Fig.12 lifting illustration

9


face the pipe string coupling or the drilling pipe tool joint(see detailed operation at 5.2) . ●The support point of the pulley must be installed 15 meters above the well head.



●Central line of the power tong head is located at 0.6m away from the vertical line of the well head in free suspension state. ●Avoid breaking the hose due to twisting in use. ●The piston rod extends and faces downward when installing the bucket.

●When the backup tong directly faces the pipe string coupling or the drilling pipe joint, the piston rod of the bucket should be located at half of the stroke. ●The suspension height of the hydraulic tong can be adjusted easily with the hydraulic bucket.

4.3 Installing hydraulic pipeline

See 5.3.1,5.3.2 4.4 Installing the torque control system(operation parts,

see 5.4) 4.5 Leveling(Fig.13)

●Push hydraulic power tong to the clamping position. ●Check whether tong head level or not. If it is not level, keep master tong level by adjusting four screws on the Adjusting bolt

suspension bar. Check whether the backup tong parallel to the master tong or not, if not, adjust them following the procedure of 5.6.

Fig.13

●Power tong leveling is very important, if not level, the tong head clamping will fail to work. ●Four screws should be adjusted in coordination. 4.6 Tie Back Guy (See Fig.14)

Back guy should be tied well after leveling the tong. One end o the back guy should be tied to the pin axle at the tail of the tong; the other end should be tied to the mast.

Breakin -out direction Left

The height of the end of back guy tied to the mast should be same as that of the tong. The back guy should be vertical with the central line of tong body and also be pulled tightly. Pay attention to the direction of the guy, the back guy should be tied to the right hand side of the tong in the making-up operation but it should be on the left in the breaking-out operation when observed from the front of the tong head. Don’t tie it in the

Ri ht Makin -u direction

wrong direction(All above-mentioned are suitable for Right Hand thread, as for Left Hand thread, on the contrary.)

Fig.14 Illustration of black guy

●Back guy, which is usually soft wire rope, must be able to bear load of over 6600bf.

10


4.7 Running-in Operation

●Supply hydraulic power tong with oil. ●Control the lifting bucket; adjust the height of power tong. ●Keep free-load running at low gear for 1 to 2 minutes. ●Keep free-load running at high gear for 1 to 2 minutes. ●Test tong head running in clockwise and counter-clockwise directions, watch whether master tong and backup tong being synchronous or not. Adjust the direction of reset knob if they are not synchronous. ●The adjusting procedure is shown at 5.4. ●Open the safety door, deliver tong to the well head, watch whether the space between master tong and backup tong suitable or not. Adjust the space between them if not suitable. ●Try to clamp the pipe string at high gear, adjust system oil supply pressure by adjusting the overflow valve in the hydraulic system according to the table of the making-up torque value, shifts, torque and pressure parameter (See Fig.6) recommended by API. Note: Being synchronous means both the master tong dies and the backup tong dies and the backup tong

dies stretch out when operating the hand control valve in one direction. When operating hand control valve in the opposite direction, the jaw plate frame of the master tong and the opening gear face the opening of master tong, the jaw plate frame of the backup tong and the main body of backup tong, too. The reason for being non-synchronous are:1.the wrong direction of the reset knob; 2.wrong connection of the hoses of the backup tong is sure to slip, see 5.3.2 for the right connection method. ●Don’t disassemble hydraulic pipe at high pressure, otherwise, accidents may occur and the equipment may be damaged. ●Don’t approach the running part of hydraulic power tong by your body or clothes. ●Only operators are allowed to approach hydraulic tong to avoid any trouble caused by turnin the o eratin lever. ●The hand control valve may be slightly operated to realize gear shifting at low gear to avoid damaging the gear. 4.8 Making-up or breaking-up operation

See 5.7, 5.8 for recommended steps. ●The temperature of the hydraulic oil should not be over 65 ℃.Over heating can make hydraulic system seal fail to work and slow down the running speed of tong.

4.9 Treatment after use

Operate as the following procedures after the work is finished. ●Cut off power source. ●Remove the high-pressure hose. ●Protect oil inlet and outlet to prevent sand or iron scraps getting in. ●Check fastening parts, fasten the loose parts. ●Put down power tong, place it in an even place, otherwise the tong will be damaged if the place is not even. ●Clean and maintain power tong as (6). ●Proper treatment prolongs the life of power tong after use.

5.6Adjusting braking torque

Adjusting screw

Lower the breaking torque: add lubricating cream to the friction disc or loose the braking spring to lower the braking torque to prolong the life of the friction disc. Increase the braking torque: loose lock nut (12AZ-67), Braking spring wrench each screw evenly (12AZ-67). Properly press braking spring (12AZ-32), finally tighten the lock nut(see Fig.31 this method applies only to install Lock nut adjustable braking mechanism) .
