Detailed Description
The embodiments of the invention will be described in detail below with reference to the accompanying fig. 1 to 2, but the invention can be implemented in many different ways as defined and covered by the claims.
According to the description of the background art, the support plate 3 is arranged at the upper part of the middle bearing 4, when a worker moves the walking beam 0, the locking nut 2 is firstly loosened, then the jackscrew at one side of the support plate 3 is loosened, and then the jackscrew at the other side of the support plate 3 is tightened, so that the problem that the transverse size of the loosening, namely the axial moving distance of the jackscrew, needs to be judged by the naked eyes of the worker due to the fact that the end face of the jackscrew and the side face of the support plate 3 are not on the same plane, and accuracy is poor.
With reference to fig. 1 to 2, in the walking beam deviation auxiliary measuring device provided by the present invention, the jackscrew at the lower part of the walking beam 0 passes through the side of the support plate 3 welded with the walking beam 0 and acts on the upper part of the middle bearing 4, two sides of the support plate 3 are respectively provided with a pair of jackscrews (jackscrew I1 a and jackscrew II 1b), the side of the support plate 3 is fixedly provided with a square projection 5, the middle part of the side of the support plate 3 is transversely provided with a guide rod 9, the guide rod 9 is movably sleeved with a sliding sleeve 7, the outer edge of the sliding sleeve 7 is transversely fixedly provided with a positioning plate 6, one side of the positioning plate 6 can be attached to the end surface of the jackscrew (jackscrew I1 a and jackscrew II 1b), and the other side of the positioning plate 6 can be attached to the side of the projection 5; the front surface of the positioning sheet 6 and the front surface of the support plate 3 can be positioned on the same longitudinal surface; a compression spring 8 is sleeved on the guide rod 9 between the sliding sleeve 7 and the support plate 3, one end of the compression spring 8 acts on the end face of the sliding sleeve 7, and the other end of the compression spring 8 acts on the side face of the support plate 3.
According to the structure of the above embodiment, it can be found that, due to the characteristics of the compression spring 8, when the jack screw (the jack screw I1 a and the jack screw II 1b) is rotated to cause the axial displacement, under the action of the elastic force of the compression spring 8, the positioning plate 6 can be always attached to the end surfaces of the jackscrews (the jackscrew I1 a and the jackscrew II 1b), so that, when measuring the axial moving distance of the jackscrew (the jackscrew I1 a and the jackscrew II 1b), only the moving distance of the positioning sheet 6 is required to be measured, specifically, the distance L between the inner side surface of the positioning sheet 6 and the side surface of the support plate 3 is measured, then the thickness of the bump 5 is subtracted by the L, because the spacer 6 can follow the terminal surface of jackscrew (jackscrew I1 a and jackscrew II 1b) and extend, and the preceding of spacer 6 can be in same longitudinal plane with the preceding of extension board 3, so the staff just can use the numerical value of L of accurately surveying fast of instruments such as rulers.
With reference to fig. 1 to 2, the bumps 5 are four bumps 5 welded on two sides of the support plate 3, and one side of the support plate 3 has a pair of bumps 5; the locating tab 6 can act simultaneously on a pair of projections 5 on one side of the strip 3.
In the above-described embodiment of the present invention, an embodiment in which one side of the strip plate 3 has a pair of projections 5 is preferably used, in order to make each of the jackscrews correspond to one projection 5, and in other embodiments of the present invention, one projection 5 may be provided only on each of both sides of the strip plate 3.
Referring to fig. 1 and 2, the positioning plate 6 is an elastic metal plate.
The utility model discloses an among the above-mentioned embodiment, spacer 6 uses the preparation of elastic metal material, this embodiment has important effect in concrete operation process, the background art is described is the problem that walking beam 0 exists when horizontal lateral shifting, but when the position of actual adjustment walking beam 0, still can adjust walking beam 0's angle usually, even make walking beam 0 take place the horizontal rotation, at this moment, can make extension board 3 appear different axial displacement with two jackscrews of one side, set up spacer 6 into elastic metal piece and just can utilize its elastic deformation to make extension board 3 appear different axial displacement with two jackscrews of one side, spacer 6 can both paste the terminal surface of tight jackscrew simultaneously, thereby guarantee that the distance between the medial surface of spacer 6 and the side of extension board 3 subtracts the axial displacement distance that the thickness gained numerical value of lug 5 is the jackscrew.
To sum up, this utility model creatively draws forth one perpendicular and with the extension board 3 preceding plane that is in same longitudinal plane with the jackscrew terminal surface for the axial displacement distance that can accurately obtain the jackscrew promptly of spacer 6 on this plane is measured to the staff, compares with prior art, has the advantage that the accuracy is high, can effectively improve the efficiency of polished rod centering operation, and this utility model still has simple structure, easy preparation, the advantage of easy installation.
