Abstract
A drilling slush pump piston disassembly and assembly device comprises a screw, a nut, a movable joint, a pin shaft, a sleeve, a slush pump piston, a slush pump housing and a locking device, wherein the external thread of the screw is screwed with the internal thread of the nut, the nut is clamped on the slush pump housing, the right end of the screw is connected with the movable joint in moving mode, the movable joint is connected onto the sleeve through the pin shaft, a clamping groove is formed in the end of the slush pump piston, the locking device is installed in the side direction of the sleeve, the locking device is locked in the clamping groove of the slush pump piston, the slush pump piston can be pulled out from a cylinder sleeve only by rotating the screw, and therefore the slush pump piston for well drilling can be convenient and quick to disassemble and replace, time and labor are saved, work efficiency is high, labor intensity is low, the slush pump piston can not be damaged, assembly quality can be guaranteed, no unprofessional operation problem exists, no potential safety hazard exists, and the drilling slush pump piston disassembly and assembly device has prominent economic benefit and social benefit.
Description
technical field:
The utility model is the maintenance unit of the slurry pump of oil field welldrilling, is a kind of drilling mud pump piston attaching/detaching apparatus.
background technique:
Slurry pump is the important component part of oil drilling industry drilling equipment, and wherein piston is the easily damaged parts of slurry pump, changes frequent.The method of changing at present piston is: first make pump running by manpower or mechanical force, reciprocating piston is pushed into cylinder sleeve upper dead center, open Jie's bar clip, oppositely turn again pump, Jie's bar is retreated to bottom, between Jie's bar and piston rod, add cushion block, then turn after piston is released cylinder sleeve by pump and take out; When installation, knocking piston with the ironware such as hammer, steel pipe makes it enter cylinder sleeve.The method of this replacing piston belongs to for operating against regulations, has major safety risks, and personal injury accident easily occurs; Changing the operation of piston at least needs 3 people to coordinate just to complete, waste time and energy, inefficiency, and labor intensity is large; Easily damage piston, assembly quality is poor, affects the working life of slurry pump.
summary of the invention:
The purpose of this utility model is to provide a kind of drilling mud pump piston attaching/detaching apparatus, the mud piston that dismounting drilling well is easily and efficiently used.
The purpose of this utility model is achieved in that and comprises mud piston, slurry pump housing, also comprise screw rod, nut, union, bearing pin, sleeve, locking device, the outside thread of screw rod and the internal thread of nut screw, nut buckle is on slurry pump housing, the right-hand member of screw rod is flexibly connected with union, and union is connected on sleeve by bearing pin, in the end of mud piston, draw-in groove is set, in the side direction of sleeve, locking device is installed, locking device is locked in the draw-in groove of mud piston.
The beneficial effects of the utility model: rotary screw just can pull out mud piston from cylinder sleeve, the mud piston that disassembling, assembling and replacing drilling well is easily and efficiently used, time saving and energy saving, working efficiency is high, and labor intensity is little, can not damage mud piston, can ensure assembly quality, the problem that does not have operation against rules, does not have potential safety hazard, has significant economic benefit and social benefit.
brief description of the drawings:
Fig. 1 is the utility model embodiment's erection drawing.
embodiment:
Below in conjunction with Fig. 1, the utility model embodiment is described.
From accompanying drawing 1, embodiment of the present utility model comprises screw rod 1, nut 2, union 3, bearing pin 4, sleeve 5, mud piston 7, slurry pump housing 8, locking device 9, the internal thread of the outside thread of screw rod 1 and nut 2 screws, nut 2 is buckled on slurry pump housing 8, the right-hand member of screw rod 1 is flexibly connected with union 3, union 3 is connected on sleeve 5 by bearing pin 4, in the end of mud piston 7, draw-in groove 6 is set, locking device 9 is installed in the side direction of sleeve 5, and locking device 9 is locked in 6 li of the draw-in grooves of mud piston 7.
Nut 2 is stuck and can not moves left and right, when rotary screw 1, under threaded function, screw rod 1 is walked left, mud piston 7 is pulled out and changed from cylinder sleeve, after mud piston 7 pulls out from cylinder sleeve, rotational locking device 9, angle of swing is greater than 90 °, the front tongue of locking device 9 just can depart from draw-in groove 6, and mud piston 7 is separated with sleeve 5.The utility model also can pack mud piston 7 in cylinder sleeve into.Mud piston 7 first takes off bearing pin 4 while packing in cylinder sleeve, sleeve 5 and union 3 are thrown off, contra rotating screw 1, under threaded function, screw rod 1 is walked to the right, union 3 is withstood mud piston 7 and is entered in cylinder sleeve, and therefore, mud piston 7 is installed does not need the used time to knock with the ironware such as hammer, steel pipe, mud piston 7 can not be broken, and can ensure assembly quality.
The effect of union 3 be screw rod 1 while rotating sleeve 5 can not rotate.
