Description
Technical field
The utility model relates to a kind of maintenance tool of oil pumping machine crank guide, and concrete is the drawer of oil pumping machine crank guide.
Background technology
In the production run process of rod-pumped well, because crank-pin overlaps in use for some time the too much greasy filth that might get rusty or deposit in the guide, in addition damaged; So when changing crank pins with adjustment oil pumper stroke; 1), what use when choosing guide is conventional simple tools the crank guide of choosing is unusual difficulty, but also has following point:, instrument contacts with the guide partial face; Guide might cause the distortion of guide internal diameter because of discontinuity, even damages.2), normally two people operation when choosing guide, one of them people is holding up instrument, another person knocks instrument, and the danger of hindering hand is arranged; And there is certain potential safety hazard in that people who is holding up instrument near crank.3), the instrument because of having good method and being fit to, so the work of the guide of choosing is time-consuming effort again, operating efficiency is very low.
Summary of the invention
The purpose of the utility model provides a kind of Crank Pin on Pumping Units cover take-off device; Use this take-off device oil pumping machine crank guide of choosing to guarantee to be removed the serviceability rate of guide; The purpose of can reach safety, taking out fast; And this take-off device is simple in structure, uses and carries all easily, has very strong practicality.
For realizing the foregoing invention purpose; The technical scheme that the application adopts is: connect fixed Crank Pin on Pumping Units cover take-off device; Comprise round steel post, lead screw, circular steel plate and baffle plate; A horizontal end face center at the round steel post is provided with screwed hole, and the threaded one end of lead screw is connected in this screwed hole, and the length of said lead screw is greater than the length of crank guide; The external diameter of said circular steel plate is greater than the internal diameter of crank guide, less than the external diameter of crank guide, and its center is provided with circular hole, is enclosed within on the lead screw then to fix with first locking nut; Said its centre is provided with through hole, and the horizontal direction of baffle plate or the length of vertical direction is greater than the internal diameter of crank guide, or the length of level and vertical direction is all greater than the internal diameter of crank guide, and baffle-plate-sleeve is at the other end of lead screw and fix with second locking nut.
Above-mentioned baffle plate preferably adopts the U-shaped baffle plate.
The application's beneficial effect:
1, this crank-pin cover take-off device adaptability is strong, and applicable to various model oil pumpers, during the crank guide of the different size of choosing, the round plate that only needs to change appropriate size gets final product;
2, tearing open when choosing the crank guide because of this take-off device; Sledgehammer strike is on the round steel post; The suffered power of crank guide is uniform like this; And the both ends of the surface of crank guide all have the steel plate protection, so the crank guide that takes out can not sustain damage, the guide contravariant of taking out of can effectively avoiding requiring great effort becomes the phenomenon of waste product to take place;
3, the attended operation of take-off device and crank guide is simple, and the whole operation process is single can be accomplished, and has alleviated labour intensity, has improved efficiency, and according to statistics, individual well guide time of choosing can improve 20 minutes;
4, use the choose operating process of crank guide of this take-off device as safe as a house, overcome when using simple tool or plain mode in the past, a people holds up instrument one people to knock the hidden danger of being brought that is prone to hinder hand;
5, this take-off device is simple in structure, with low cost, easy to carry, uses through field worker test, has obtained trier's extensive praise, for oil field workman's maintenance work provides great convenience.
Description of drawings
Fig. 1 is the structural representation of the application's crank-pin cover take-off device.
Fig. 2 is the structural representation of U-shaped plate.
The specific embodiment
Be example with the take-off device that is applicable to existing CYJ5 type-14 type oil pumper below, the fixed Crank Pin on Pumping Units cover of the application's connection take-off device be further described:
By shown in Figure 1: this connects fixed crank-pin cover take-off device, comprises round steel post 1, lead screw 2, circular steel plate 3 and baffle plate 4.170 millimeters of the length of said round steel post 1,60 millimeters of diameters, in one of them horizontal end face centre-drilling hole and tapping of round steel post 1, screw thread M20, length is not less than 5 millimeters; Round steel post 1 is threaded on the lead screw 2.
Totally three of above-mentioned circular steel plates 3; Its external diameter is respectively 91 millimeters, 104 millimeters, 129 millimeters; Be applicable to the specification of the various crank guidees on the existing CYJ5 type-14 type oil pumper, because the oil pumper model is brought in constant renewal in, the diameter of circular steel plate 3 can be adjusted, change according to actual conditions; The thickness of circular steel plate 3 is more than or equal to 12 millimeters, mainly be guarantee when stressed not yielding; In the centre-drilling hole of circular steel plate 3, diameter 20 millimeters+20 roads in hole, circular steel plate 3 is enclosed within lead screw 2, but move left and right is freely; The two sides of circular steel plate 3 requires smooth; This circle steel plate 3 by first locking nut 5 fastening after; Circular steel plate 3 closely contacts with round steel post 1, can guarantee like this to get to pull out when operating, and acts on percussion power on the round steel post 1 of take-off device and is delivered to crank-pin better, more uniformly and puts.
As shown in Figure 2: above-mentioned baffle plate 4 be shaped as U-shaped, its length is greater than 140 millimeters, wide 90 millimeters, thickness is more than or equal to 8 millimeters; U-shaped baffle plate center circle diameter 20 millimeters+20 roads, the U-shaped baffle-plate-sleeve is on lead screw 2, but move left and right is freely; It is smooth that U-shaped baffle plate two sides requires, this U-shaped baffle plate by second locking nut 6 fastening after, the U-shaped baffle plate closely contacts with crank guide other end.Certainly baffle plate 4 can be other shapes also, as long as the function that meets the demands is a rectangle such as baffle plate 4, the center is provided with through hole, and baffle plate 4 is enclosed within on the lead screw 2 through this through hole, and can be fixing by second locking nut 6.
300 millimeters of the length of above-mentioned lead screw 2,20 millimeters of diameters, reach guarantees that greater than 200 millimeters second locking nut 6 that is connected on the lead screw 2 can connect fastening U-shaped baffle plate 4 effectively.
The concrete size of each parts of take-off device that provide above is for the design feature of explanation the application take-off device of image, can not be interpreted as the qualification to the application; Iff is that part dimension is different, or the crank-pin that the constant just simple shape of component function changes overlaps take-off device, and promptly being regarded as is the technical scheme identical with the application.
During use, round steel post 1 and lead screw 2 are connected, put circular steel plate 3 and fixing with first locking nut 5; Then lead screw 2 is passed the crank guide; The good circular steel plate 3 of check and correction contacts interplanar distance with the crank-pin cover and leaves; Make the two tight contact; Put U-shaped baffle plate 4 backs in the outside, the other end of crank guide and fix with second locking nut, take-off device is fixedly connected as a wholely with the crank guide at this moment, and is fixed on the crank; Last needs a workman with knocking the afterbody that instrument knocks round steel post 1, constantly moves ahead behind the percussion power that the crank guide is passed over, and can the crank-pin cover be taken out.
