The main technical parameters: the input speed of the car is controllable within the range of 10~200r/min; the output speed is 1~20r/min; the output torque is 1900Mm; the chassis adopts four-wheel trailer type, the wheelbase is 3.2m, the track is 2.3m. : DLC-1 cable drum trailer has a chassis, roller bracket, hydraulic oil motor, reducer, hydraulic operating control valve and pipeline, roller brake mechanism, leveling hydraulic jack legs and so on.
First, hoist the new cable or repair cable to one of the roller brackets in the workshop, drag it to the job well site with a tractor, connect the hydraulic oil pipeline of the oil motor to the hydraulic oil pump of the workover rig, and operate the six-way valve. Adjust the vehicle to a horizontal position, and at the same time, fix the vehicle with a ground anchor. When lifting the old cable, the hydraulic power oil is switched to the empty drum drive oil motor through the reversing valve; when the new cable is lowered, the reversing valve is switched to the drum drive motor with the new cable; the rotation speed of the drum is controlled by the hydraulic pressure The opening of the valve is operated to control the braking of the drum by the brake mechanism.
According to the calculation of 116 electric pump wells operated in 2002, the annual transportation and lifting costs were 66,800 yuan, and the annual labor saving cost was 143,800 yuan. The installation cost of the device was 45,600 yuan, and the service life was 8-10 years. Maintenance costs are 8,900 yuan. The use of DLC-1 cable drum trailer eliminates the hidden dangers during the construction of electric pump wells, reduces the cost of vehicle use, improves work efficiency, reduces labor intensity, and reduces the quality of engineering caused by cable damage. Rework.
