[0025] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiment of the utility model is described in detail below with the drawings of the specification.

[0026] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be practiced according to other embodiments that do not require the specific details described in this description. Therefore, the present application is not limited to the embodiments described herein and can be practiced according to other embodiments that do not require the specific details described in this description.

[0027] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. The present application provides the following embodiments.

[0028] Referring to Figs. 1-3 The present application provides an embodiment: a coupling top sleeve fixing device, comprising a shaft pipe 1, a first through hole is formed in the shaft pipe 1, a threaded rod 2 is fixedly connected at the center of the rear end of the shaft pipe 1, a reducer rotor 3 extending from a reducer is threadedly connected to the outer wall of the threaded rod 2, a threaded hole is formed at the center of the front end of the reducer rotor 3, the outer wall of the threaded rod 2 is installed in the threaded hole, a top sleeve body 4 is sleeved on the front end of the outer wall of the reducer rotor 3, the connection structure between the threaded rod 2 and the reducer rotor 3 can install one end of the outer wall of the shaft pipe 1 in the top sleeve body 4, a first flange 5 is fixedly connected to the front end of the outer wall of the top sleeve body 4, a pin shaft 6 penetrates the shaft pipe 1, the outer wall center of the pin shaft 6 is installed in the first through hole inside the shaft pipe 1, a jack support 7 penetrates both ends of the outer wall of the pin shaft 6, second through holes penetrating front and back are formed at the bottom of both sides of the inner wall of the jack support 7, the inner diameters of the first through hole and the second through hole are the same, a limiting plate 8 is fixedly connected to one end of the bottom of the jack support 7, a hydraulic jack 9 is installed in the jack support 7, a pull sleeve 10 is slidingly connected to both sides of the inner wall of the jack support 7, symmetrical sliding grooves 11 are formed at both sides of the inner wall of the pull sleeve 10.

[0029] The outer wall of the pin shaft 6 penetrates the inner wall of the second through hole in the inside of the jack support 7, the inner wall of the sliding groove 11 and the inner wall of the first through hole in the inside of the shaft tube 1 in turn, and the jack support 7 can be fixed on the outer walls on both sides of the pull sleeve 10. The outer wall of the pin shaft 6 can slide back and forth in the inner wall of the sliding groove 11. By setting the connecting structure between the pin shaft 6 and the sliding groove 11, the jack support 7 can slide back and forth on the outer walls on both sides of the pull sleeve 10, and the movement range of the jack support 7 is limited. By setting the limiting plate 8, the stability of the jack support 7 can be improved, and the pushing direction of the pull sleeve 10 is limited. The rear end of the pull sleeve 10 is fixedly connected with the second flange 12. First, the hexagonal bolts are sequentially inserted into the through holes provided at the outer edges of the second flange 12 and the first flange 5. These through holes are specially designed for connecting the two flanges, so that the bolts can smoothly pass through and be fixed. Then, the hexagonal nuts are installed on the protruding ends of the hexagonal bolts, i.e. the parts exposed after the bolts pass through the two flanges. After installing the nuts, the nuts need to be tightly screwed, so as to ensure that the bolts and the nuts are tightly combined, thereby firmly fixing the first flange 5 and the second flange 12 together. In this way, the two flanges are tightly connected to form a stable structure. When the top sleeve body 4 needs to be installed, since the first flange 5 and the second flange 12 have been firmly fixed together, we can use this stability to improve the stability of the pull sleeve 10 in pushing the top sleeve body 4. The function of the pull sleeve 10 is to accurately position and push the top sleeve body 4 into the predetermined position, and the stable flange connection ensures the smooth progress of this process.

[0030] After the installation of the top sleeve body 4 is completed, the entire structure has reached the expected stable state. At this time, the hexagonal bolts originally used to connect the two flanges have completed their tasks, so these hexagonal bolts can be removed for the next assembly or use. After the bolts are removed, the two flanges remain tightly connected to ensure the stability and reliability of the entire system.

[0031] The extrusion pad 13 is installed at the center position of the front end of the pull sleeve 10. The function of the extrusion pad 13 is to effectively absorb and reduce the amplitude generated during the contact between the front end of the pull sleeve 10 and the hydraulic jack 9. In this way, the extrusion pad 13 can significantly reduce the vibration caused by contact, thereby protecting the connecting part between the hydraulic jack 9 and the pull sleeve 10 from damage caused by violent vibration. This structure not only improves the service life of the equipment, but also ensures the safety and stability during operation. By setting the extrusion pad 13, the service life of the equipment is improved, and the stability and reliability of the entire pushing system are ensured. The second flange 12 is arranged in front of the first flange 5, the movable end of the hydraulic jack 9 is arranged in front of the extrusion pad 13, and the outer wall of the pin shaft 6 can slide in the inner wall of the sliding groove 11.

[0032] The above is further detailed description of the utility model in combination with specific embodiments, and cannot be determined that the utility model specific implementation is limited to these descriptions. For ordinary skilled in the art to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope determined by the claims submitted by the utility model.
