Description
Technical Field
The utility model relates to a coal mine production technical field, in particular to an appurtenance that is used for hydraulic support to transfer jack installation from top to bottom specifically is a location frock that jack installation was transferred at the bottom of hydraulic support.
Background
The bottom adjusting jack is an important component of the hydraulic support. In coal mine production, especially in the case of a floor with poor conditions and a coal bed inclined working face, the bracket can be inclined after moving, and bracket management and push-sliding operation are not facilitated. The bottom adjusting jack is used for adjusting adjacent supports in the support moving process so as to ensure the whole synchronization and stability of the supports, effectively manage the supports and a supporting top plate, facilitate smooth pushing, and ensure safe and efficient production.
In the actual spot-assembling process, errors (eccentricity) in positions can be generated due to the difference of the levels of operators and errors generated by multiple measurements in the spot-assembling process of the base sleeve, the guide cylinder and the stop pin seat, so that the bottom adjusting jack cannot be assembled, the pin shaft cannot be inserted, the position is deviated and the like, and thus rework is caused. In order to reduce the occurrence of the phenomenon and reduce the labor intensity of workers, an auxiliary tool for installing the bottom-adjusting jack on the hydraulic support should be designed in combination with production practice.
Disclosure of Invention
The utility model aims at solving the problems existing in the prior art and providing a positioning tool for installing a hydraulic support bottom adjusting jack.
The utility model discloses a realize through following technical scheme:
a positioning tool for installing a hydraulic support bottom adjusting jack comprises a first positioning sleeve, a second positioning sleeve and a connecting sleeve; the first positioning sleeve and the second positioning sleeve are respectively arranged at two ends of the connecting sleeve, and an end hole is formed in the wall of the first positioning sleeve; the first positioning sleeve and the connecting sleeve are fixedly connected through a first flange, and the second positioning sleeve and the connecting sleeve are fixedly connected through a second flange; the first positioning sleeve, the first flange, the connecting sleeve, the second flange and the second positioning sleeve are positioned on the same axis.
The utility model discloses each position sleeve and flange in the location frock are axiality and terminal surface hole, and transfer jack overall dimension phase-match with the end, can replace traditional assembling with it at the point dress in-process of reality and rule, just so can transfer the intelligent welding of jack base sleeve, guide cylinder and fender key seat for the end and provide stable positional parameter, the intelligent welding of the hydraulic support base of being convenient for has guaranteed the concentricity of base sleeve and guide cylinder, does benefit to the zero error installation of adjusting the jack at the end.
The utility model discloses frock design science, simple structure, preparation are easy, low cost, convenient to use, through its positional parameter of location base sleeve, guide cylinder and backing pin seat that can be perfect, the workman's operation of being convenient for in actual production has avoided the error, has improved the quality of assembling, has saved man-hour and consumptive material, and is light durable moreover, and the suitability is strong, has thoroughly solved the problem that hydraulic support transfers jack installation difficulty at the bottom of the upper segment, can use widely in all kinds of hydraulic support.

Detailed Description
In order to make the present invention better understood by those skilled in the art, the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
As shown in fig. 1 and 2, a positioning tool for mounting a hydraulic support bottom-adjusting jack comprises a first positioning sleeve 1, a second positioning sleeve 2 and a connecting sleeve 3; the first positioning sleeve 1 and the second positioning sleeve 2 are respectively arranged at two ends of the connecting sleeve 3, and an end hole 4 is formed in the wall of the first positioning sleeve 1; the first positioning sleeve 1 and the connecting sleeve are fixedly connected through a first flange 5, and the second positioning sleeve 2 and the connecting sleeve 3 are fixedly connected through a second flange 6; the first positioning sleeve 1, the first flange 5, the connecting sleeve 3, the second flange 6 and the second positioning sleeve 2 are located on the same axis.
The utility model discloses the preparation method of frock does: firstly, machining the inner diameter and the outer diameter of a flange into finished products, specifically numerical control lower round materials, and machining the finished products into a first flange 5 and a second flange 6 to ensure that the flanges are concentric inside and outside; secondly, processing the outer diameters of the first positioning sleeve 1, the second positioning sleeve 2 and the connecting sleeve 3 into finished products, and drilling holes on the cylinder wall of the first positioning sleeve 1 to form an end hole 4; and finally, the first positioning sleeve 1, the first flange 5, the connecting sleeve 3, the second flange 6 and the second positioning sleeve 2 are welded into a whole in sequence, and the coaxiality of the first positioning sleeve, the first flange 5, the connecting sleeve 3, the second flange 6 and the second positioning sleeve 2 is ensured. The tool is matched with the bottom adjusting jack in size, so that the combined concentric tool is just like the bottom adjusting jack and can be used for replacing scribing and assembling in the actual spot assembling process, thereby accurately positioning the position parameters of the base sleeve, the guide cylinder and the stop pin seat and ensuring the perfect installation of the bottom adjusting jack.
