Description
Technical field
The utility model relates to the provision for disengagement of the corollary apparatus of oil field equipment, particularly a kind of crank pin for pumping unit.
Background technology
On the beam pumping unit of using at oil extraction in oil field, there is crank, when adjusting the stroke of oil pumper or changing the crank pins damaging, crank pins need to be taken apart from the pin-and-hole of crank, then reinstalling.The method of dismantling at the scene at present crank pins is with sledgehammer, to impact crank pins by an above staff, crank pins is exited from the crank of oil pumper, because crank is in specific position, now very inconvenient when making to dismantle crank pins in this way, sledgehammer impacts the power of not using, and operator is dangerous, easily cause personal injury, because oil pumper is in long-term work process, there is etching problem again, make its dismounting crank pins more difficult.This is the existing weak point of prior art.
Utility model content
Technical problem to be solved in the utility model, is exactly for the existing deficiency of prior art, and a kind of provision for disengagement of crank pin for pumping unit is provided, and can easily crank pins be disassembled.
This programme is achieved by the following technical measures: a kind of provision for disengagement of crank pin for pumping unit, it comprises crank, crank pins, two hooks, peg, support and walking screw rod, described crank pins is arranged in crank, the cross section of described support is several character form structures, the two ends of described support coordinate pressing plate to be fixedly connected with crank by bolt assembly, on described pressing plate, be provided with through hole, described pressing plate is enclosed within on shank of bolt, described two hooks are symmetricly set on the both sides of crank pins, the outer rim of crank pins is caught in described hook one end, the other end of hook is provided with through hole and is enclosed within on peg, on described peg, be provided with external screw thread, described peg two ends are provided with hook setscrew nut, one end of described walking screw rod is fixedly connected with peg middle part, the other end of walking screw rod is provided with driving handle, described walking screw rod coordinates installation with the screwed hole that mid-stent arranges.
Above-mentioned hook is L shaped structure, one end of hook and the laminating of the edge of crank pins, and the other end of hook is by circle hole sleeve on peg, and hook setscrew nut will be linked up with fixing.
The beneficial effects of the utility model have above-mentioned technical scheme known: rotarily actuate handle, the screw rod that makes to walk drives the direction that peg is extracted to crank pins to walk, thereby crank pins is pulled out from the pin-and-hole of crank.The edge mate of hook setscrew nut and crank pins will be linked up with location, make steady when dismounting crank pins, safety, reliable; Support coordinates pressing plate to be fixedly connected with crank by bolt assembly, facilitates installation and removal, practical.Use the provision for disengagement of the crank pin for pumping unit that the utility model proposes can complete easily the dismantlement work of crank pins, save time, laborsaving, operating efficiency is high, and staff is safe from danger when operation.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-crank, 2-crank pins, 3-bolt assembly, 4-support, 5-hook, 6-peg, 7-links up with setscrew nut, the 8-screw rod of walking, 9-driving handle, 10-pressing plate.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in the figure, a kind of provision for disengagement of crank pin for pumping unit, it comprises crank 1, crank pins 2, two hooks 5, peg 6, support 4 and walking screw rod 8, described crank pins 2 is arranged in crank 1, the cross section of described support 4 is several character form structures, described support 4 coordinates pressing plate 10 to be fixedly connected with crank 1 by bolt assembly 3, on described pressing plate 10, be provided with through hole, described pressing plate 10 is enclosed within on shank of bolt, described two hooks 5 are symmetricly set on the both sides of crank pins 2, the outer rim of crank pins 2 is caught in described hook 5 one end, the other end of hook 5 is provided with through hole and is enclosed within on peg 6, on described peg 6, be provided with external screw thread, described peg 6 two ends are provided with hook setscrew nut 7, one end of described walking screw rod 8 is fixedly connected with peg 6 middle parts, the other end of walking screw rod 8 is provided with driving handle 9, described walking screw rod 8 coordinates installation with the screwed hole that support 4 middle parts arrange.
Above-mentioned hook 5 is L shaped structure, one end of hook 5 and the laminating of the edge of crank pins 2, and the other end of hook 5 is by circle hole sleeve on peg 6, and hook setscrew nut 7 will be linked up with 5 and fix.
During use, rotarily actuate handle 9, the screw rod 8 that makes to walk drives the direction that peg 6 is extracted to crank pins 2 to walk, thereby crank pins 2 is pulled out from the pin-and-hole of crank 1.
In the utility model, without the technical characterictic of describing, can pass through or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned embodiment; the variation that those of ordinary skill in the art makes in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
