Description
Technical field:
The utility model relates to a kind of aid of dismantling the oil pumper parts, and concrete is the extractor of crankpin bush.
Background technology:
When oil pumper is carried out the repair demolition crank-pin, because of crankpin bush closely contacts with the crank hole wall, frictional force is big, and lining easily with crank hole corrosion be in the same place, when maintenance or replacing crankpin bush, lining is difficult for unloading down from crank hole, for early stage oil pumper, usually the method for dismounting that adopts is to use the instrument of hammer and so on firmly to strike, pound, can produce hard defects such as cut in sleeve surface or crank hole surface like this, also need after disassembling cut is carried out milled processed, pretty troublesome, time-consuming; For two horse head oil pumpers of present use, because of reasons in structure, working environment is narrow and small, can not pound crankpin bush from the reduction box side, and the dismounting crankpin bush has just more been required great effort; Certainly other have the machine of toggle, and also there is same problem in the dismounting of crankpin bush.
The utility model content:
Technical problem to be solved in the utility model provides a kind of extractor of quick release crankpin bush, uses this extractor to carry out lining taking-up operation and can reduce the lining breakage rate, and can improve the maintenance efficiency of oil pumper.
For solving the problems of the prior art, technical solution of the present utility model is: this Crank Pin on Pumping Units bush extractor, comprise a main thick stick, main thick stick one end is provided with screw thread, connect the locking plug, thick stick is provided with external screw thread on one's body, be connected with clamp nut, the other end is provided with screw thread, connect fastening plug, be with two catch between clamp nut and fastening plug, the diameter of two catch is slightly smaller than the external diameter of crankpin bush to be removed, the position of regulating clamp nut can make two catch with crankpin bush jam-packed to be removed, and the thick stick between locking plug and clamp nut is with the bump slide block on one's body.
The other end of certain main thick stick also can be designed as the termination and main thick stick is an one, and the diameter of termination is greater than main thick stick diameter, in order to block catch.
In order in the dismounting lining, to connect this extractor faster, be the radially gap of starting point near having with the center of circle on the catch of main thick stick termination.
Technique effect of the present utility model is: the crankpin bush and the crank hole surface of dismantling do not applied active force in this Crank Pin on Pumping Units bush extractor operating process, just can not damage lining and crank hole yet, the just simple bump slide block that slides fast when operating in addition, the vibration force of utilizing bump to produce is become flexible crankpin bush and then is come off, so operate very laborsaving, easy, obviously shorten maintenance time, and fool proof.
Description of drawings:
Fig. 1 is the structural representation of each parts of the utility model;
Fig. 2 is the schematic diagram of the utility model user mode.
Fig. 3 is the structural representation of catch 7.
1-locking plug, 2-bump slide block, 3-master's thick stick, 4-clamp nut, 5-catch, 6-crankpin bush, 7-catch, 8-master's thick stick screw thread, the fastening plug of 9-, 10-catch gap to be removed among the figure
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is in conjunction with Fig. 2, shown in Figure 3, and Crank Pin on Pumping Units bush extractor of the present utility model comprises a main thick stick 3, main thick stick 3 one ends are provided with screw thread, connect locking plug 1, described screw thread can be that external screw thread also can be an internal thread, as long as match with the locking plug; Thick stick is provided with external screw thread 8 on one's body, is connected with clamp nut 4, and the other end is provided with screw thread, connect fastening plug 9, the other end of certain main thick stick also can be designed as the termination and main thick stick 3 is one, and the diameter of termination its objective is in order to block catch 7 greater than the diameter of main thick stick 3; Between clamp nut 4 and fastening plug 9, be with two catch 5,7, during use for Fast Installation, can be provided with on the catch 7 one from the center of circle radially gap 10, then, fast as long as insert main thick stick 3 from gap 10; The diameter of two catch 5,7 is slightly smaller than the external diameter of crankpin bush to be removed 6, the position of regulating clamp nut 4 can make two catch 5,7 with crankpin bush to be removed 6 jam-packeds, so just can dismantle the crankpin bush of different length, certainly same main thick stick 3 is equipped with the catch of various outer diameter, just can dismantle the crankpin bush of different-diameter; The thick stick that locking plug 1 and clamp nut are 4 is with bump slide block 2 on one's body, and promptly clashing into slide block 2 can move along main thick stick 3.
During use from fastening plug 9 ends, at first catch 7 is inserted on the main thick stick 3 from gap 10, then main thick stick is inserted in the crankpin bush 6 to be removed, overlap upper stop piece 5 more successively, screw clamp nut 4, put bump slide block 2, tighten locking plug 1, after all connecting, the quick bump slide block 2 bump locking plugs 1 that slide, the result of multiple impact is that crankpin bush to be removed slowly becomes flexible in crank hole, and then crankpin bush is disassembled from crank hole.The order of connection also can specifically be decided on site environment and other factors from locking plug 1 end when using certainly.
This Crank Pin on Pumping Units bush extractor has completed in First Oil Production Plant of Daqing Oilfield Co., Ltd two ore deposits and has dropped into on-the-spot the use, has been subjected to operator's consistent favorable comment in the use, and the work of more complicated before making becomes easily simple.
