Abstract
The utility model relates to a device for dismounting a crank of a reduction box of an oil pumping unit used for an oil field, comprising wheels, a base, a hydraulic pump, a motor, an oil box, a control cabinet, an oil path assembly, a regulating valve, a pressure gage, a pressure release valve, hydraulic pipelines, a hydraulic cylinder, a plunger piston, pull claws, a hydraulic oil path joint and pull claw supports. The device as a whole is of a vehicle-mounted mobile structure, nylon pressure-bearing wheels are installed on the lower parts of four corners of the oblong base, the cylindric hydraulic cylinder is installed on the upper surface of the base, and the two pull claws are positioned on both sides of the hydraulic cylinder and connected with the base by the pull claw supports and pin keys; the oil box, the hydraulic pump and the oil path assembly which are installed at the left part of the base are connected with the hydraulic cylinder by hydraulic pipeline joints through the hydraulic pipelines, the control cabinet controls the motor to drive the hydraulic pump to work, and the regulating valve, the pressure gage and the pressure release valve are arranged on the oil path assembly. The device has novel design and compact structure, and can conveniently and quickly accomplish the task of dismounting the crank of a beam-pumping unit, thereby increasing the work efficiency, preventing the crank from being damaged and saving the repair cost.
Description
One, technical field
The crank extracting tool particularly was the provision for disengagement of a kind of beam pumping unit reduction box crank when the utility model related to oil field beam pumping unit reduction box maintenance.
Two, background technology
At present, in the beam pumping unit repair procedures, the dismounting of reduction box crank mainly relies on boat to hang and the artificial unloading, operation is loaded down with trivial details, labour intensity is big, and frequent starting boat is hung and navigated that to hang oblique loading bigger, boat is hung to cause damage easily, the part crank is because wedge key is tight, crank is difficult to dismounting, when the crank spreading, easily the crank top is split, cause crank to scrap, in addition the part reduction box since crank can't dismantle and cause whole driven shaft to scrap.Prior art can not solve the problems of the technologies described above.
Three, summary of the invention
The purpose of this utility model is design a kind of beam pumping unit reduction box crank provision for disengagement, and it is low to solve beam pumping unit reduction box crank removal efficiency, easily equipment and crank is caused the problem of damage in the unloading process.
Above-mentioned purpose is realized by following technical proposals:
The provision for disengagement of beam pumping unit reduction box crank comprises: wheel, base, hydraulic pump, motor, fuel tank, switch board, oil circuit aggregation, control valve, Pressure gauge, relief valve, fluid pressure line, hydraulic cylinder, plunger, pulling claw, hydraulic circuit joint, pulling claw support.Its integral body is vehicle-mounted moving structure, a nylon pressure-bearing wheel is respectively installed in the bottom, four angles of rectangle base, it is movable to be convenient in the workshop, cylindrical hydraulic cylinder be installed in base above, but hydraulic cylinder selection work pulling force 1000KN, stroke 300cm, two pulling claws are positioned at the hydraulic cylinder both sides, be connected with base with pin key by the pulling claw support, to be installed in the fuel tank of base left part by fluid pressure line, hydraulic pump, the oil circuit aggregation is connected with hydraulic cylinder by the fluid pressure line joint, the work of switch board control motor-driven hydraulic pumps, control valve, Pressure gauge, relief valve is located in the oil circuit aggregation.
According to the beam pumping unit reduction box crank provision for disengagement that such scheme is made, modern design, compact conformation, can carry out the crank dismantlement work quickly and easily, increase work efficiency, avoid damage crank, save repair cost, guaranteed oil field pumping well production needs.
Four, description of drawings
The utility model The field structural representation.
In the accompanying drawing, 1. wheel, 2. base, 3. hydraulic pump, 4. motor, 5. fuel tank, 6. switch board, 7. oil circuit road aggregation, 7-1. control valve, 7-2.
