1) Open the valve of gas pipeline from drilling rig to tongs. (This valve shall be arranged on the driller's operating table when conditions permit). 2) Start the hydraulic station (the manual reversing valve on the valve plate of the oil motor should be in the middle position to make the oil pump run under no-load condition), and the pressure of the system pressure gauge should not exceed 1.5MPa as normal. 3) After checking that the size of the jaw plate of the tong head is consistent with the size of the drill pipe joint, turn the two positioning handles on the tong head to the corresponding positions according to the indication signs according to the work needs of make-up or break-out. 4) Operate the two-way air valve of the transfer cylinder to send the pliers to the wellhead smoothly. It is forbidden to close the air valve once to make the pliers move quickly to the wellhead and cause impact. If the height of the pliers is not suitable, the lifting cylinder can be operated to lift the pliers body, so that the pliers are in a suitable position. 5) After the tongs are delivered to the wellhead and the drill pipe enters the tong through the gap, observe whether the upper and lower positioning blocks of the tong head are attached to the male and female joints, then operate the two-way air valve of the clamping cylinder to make the lower tongs clamp the joints, adjust the two-way air valve of the transfer cylinder to the middle position, and release the air. 6) According to the need of screwing-on/screwing-off, the high-low two-way air valve is turned to the corresponding position, and it is unnecessary to shift gears without stopping in use. 7) The forward and reverse rotation of the motor is realized by H-type manual reversing valve, and the position of the handle is changed according to the need of loading and unloading. 8) Reset: that is, the process of aligning the gaps of the pliers heads. H-type manual reversing valve must be operated reversely when a buckle is installed or removed, so that the tong head rotates reversely to the working state. When resetting, the high-low bidirectional air valve can be operated according to the distance between the notches, and it is realized by high-low conversion. 9) When unscrewing, when the pin is completely unscrewed from the box (that is, after the drilling tool reverses for five and a half turns or hears the sound of falling after the drilling tool is unscrewed), the manual reversing valve can be reversely operated to rotate in the screwing-up direction, so that the jaw plate of the upper tong can be disengaged from the drill pipe joint. When the upper tong loosens the drilling tool and is not aligned with the gap, it is also allowed to stop and lift the stand, and then continue to reset after lifting the stand, thus saving time. 10) Before the pin is completely unscrewed from the female pin, it is not allowed to lift it and drill with the anti-slip button. It is not allowed to lift before the upper tongs loosen the drilling tool, so as to avoid lifting the floating part or damaging the parts when the drilling tool is hit. 11) Operate the two-way air valve of the clamping cylinder to the opposite position of the working position, so as to restore the lower tongs to zero alignment with the notch. 12) Operate the two-way air valve of the transfer cylinder to make the pliers leave the wellhead smoothly. 13) If all the hydraulic valves are reset to zero after tripping or drilling, stop the pump. Close the valve of the air source coming from the drilling rig and cut off the air path. 14) When moving, the liquid gas pipe joint should be closed to prevent dirt from entering the liquid gas pipe. 15) The position of the locating handle of the upper and lower tongs depends on the requirements of make-up or break-out. However, when changing positions, the gaps of the tong head must be aligned before operation, otherwise the mechanism will fail.
5.matters need attention 1) When dismounting the jaw, be sure to turn off the hydraulic power station to avoid accidents. 2) When installing the jaws, install the jaws with the corresponding drill pipe size, and pay attention to the symmetrical installation of the left and right jaws and the selection of positioning blocks (refer to Table 1 for specific selection). 3) Check whether the hydraulic pipeline is in good condition before the pliers work, so as to prevent the operators from being injured by high-pressure oil splashing at work. At the same time, the operator should try to stay away from the high-pressure pipeline when operating. 4) After the drill pipe enters the tong head, the operator shall immediately close the protective door frame, and it is forbidden for hands or other objects to enter the tong head during work. 5) Check the safety and reliability of tail rope and lifting rope at any time.
6. All applys to API certificate.
7.Maintenance and maintenance1) Establish post responsibility system. 2) Grease the grease nipple and sliding surface before use. 3) Before use, it must be put into trial operation before use. 4) Rinse the tong head with clean water after each trip, dry it with compressed air in summer and steam in winter. The roller part of the sloping plate (Figure 1, Item 46) is cleaned and coated with a thin layer of butter. The slope is required to be clean, and the rollers and pins can rotate flexibly. 5) Hoist the lifting cylinder, transfer cylinder and clamping cylinder, wash them with clean water after each trip, dry the piston rod with cotton yarn and apply a thin layer of butter, and all the protruding parts will be collected in the cylinder. 6) After each trip, 50 ml of clean mechanical oil should be injected into the valve plate to lubricate all components of the gas path and prevent rust. 7) When the pliers are not in use, they should be stored away from the drill floor. The exposed part of the pliers head should be coated with butter, and the storage place should be clean and dry. 8) When moving, the general air inlet, inlet and outlet should be closed to prevent foreign objects from entering the pipeline. 9) When the drill pipe running in ten wells is completed, the drill pipe tongs shall be overhauled.
