Abstract
Description
Technical Field
[0001] This utility model relates to the field of pallet technology, specifically to a sprocket bracket structure. Background Technology
[0002] The track roller bracket is used to mount the track rollers of tracked excavators. Currently, the bracket structure for mounting cantilever track rollers on excavators is relatively simple.
[0003] According to a public notice (Announcement No.: CN210502932U) of a chain wheel bracket, the above application facilitates the installation and disassembly of the entire bracket by using a buffer pad to buffer the pressure between the wheel axle and the axle mounting hole.
[0004] However, in actual use, the above-mentioned equipment directly drills a wheel axle mounting hole on the bracket plate with a diameter slightly larger than that of the chain wheel axle to install the chain wheel axle. The bracket is fixed only by the pressure of the locking block. After long-term use, the bracket clamping and fixing is prone to loosening, which can lead to the bracket falling off. In view of this, we propose a chain wheel bracket structure. Utility Model Content
[0005] The purpose of this utility model is to provide a sprocket bracket structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sprocket bracket structure, including a base, a sliding groove formed on the upper surface of the base, a locking block disposed above the base, a bracket disposed above the base, a fixing mechanism disposed above the base, and a promoting mechanism disposed above the base, wherein the fixing mechanism includes:
[0007] The mounting block is fixedly mounted on the lower surface of the locking block, and a threaded rod is sleeved on the surface of the locking block, with a nut connected to the arc-shaped thread of the threaded rod;
[0008] A stabilizing block is fixedly installed on the upper surface of the base. The outer arc wall of the locking block is provided with a stabilizing groove. A stabilizing ring is fixedly installed on the surface of the bracket.
[0009] Preferably, the promoting mechanism includes a rubber strip, which is fixedly installed on the upper arc surface of the stabilizing block, a lifting block is fixedly installed on the side wall of the stabilizing block, and a limiting block is fixedly installed at the end of the stabilizing block away from the lifting block.
[0010] Preferably, the shape of the lifting block is adapted to the arc shape of the bracket, which facilitates the bracket to be lifted on the arc surface of the lifting block and facilitates the initial lifting and fixing of the bracket.
[0011] Preferably, the shape of the stabilizing groove is adapted to the shape of the stabilizing ring, and two stabilizing rings are provided. The two stabilizing rings are fixedly installed on the arc surface of the bracket in a linear array, so that the stabilizing rings can be engaged inside the stabilizing groove, thereby facilitating the fixation of the bracket.
[0012] Preferably, the surface of the locking block is provided with a through hole, the diameter of which is adapted to the diameter of the threaded rod. The threaded rod passes through the surface of the locking block, and then the two locking blocks are fixed by the action of the threaded rod and the nut.
[0013] Preferably, the shape of the mounting block is adapted to the shape of the sliding groove, so that the mounting block can slide inside the sliding groove.
[0014] Preferably, the side wall of the locking block has a groove that matches the bracket, so that the bracket can be fixedly installed inside the locking block.
[0015] Compared with the prior art, the present invention provides a sprocket bracket structure, which has the following advantages:
[0016] 1. The sprocket bracket structure is equipped with a fixing mechanism. The bracket is initially placed on the upper surface of the stabilizing block, and then the two locking blocks are moved. The stabilizing ring on the bracket is engaged with the arc surface of the locking block, thereby increasing the contact area between the bracket and the locking block and ensuring the stability of the bracket. Then, the threaded rod locks the two locking blocks together with a nut. Finally, the mounting block is fixedly installed on the upper surface of the base with bolts.
[0017] 2. This sprocket bracket structure, through the setting of a promoting mechanism, the lifting block set on the stabilizing block continues to lift the arc surface of the bracket, while the position of the bracket is limited by the limiting block, ensuring that the position of the bracket is convenient and stable. The ring is engaged with the inside of the stabilizing groove to facilitate the fixation of the bracket. Attached Figure Description

The fixing mechanism 3 includes an mounting block 301, a threaded rod 302, a nut 303, a stabilizing block 304, a stabilizing groove 305, and a stabilizing ring 306.
[0024] In one embodiment of this utility model, the mounting block 301 is fixedly mounted on the lower surface of the locking block 5, the surface of the locking block 5 is fitted with a threaded rod 302, the arc surface of the threaded rod 302 is threaded with a nut 303, the stabilizing block 304 is fixedly mounted on the upper surface of the base 1, the outer wall of the arc surface of the locking block 5 is provided with a stabilizing groove 305, and the surface of the bracket 6 is fixedly mounted with a stabilizing ring 306.
[0025] In addition, the promoting mechanism 4 includes a rubber strip 401, which is fixedly installed on the upper arc surface of the stabilizing block 304. A lifting block 402 is fixedly installed on the side wall of the stabilizing block 304. A limiting block 403 is fixedly installed at the end of the stabilizing block 304 away from the lifting block 402. The shape of the lifting block 402 is adapted to the arc surface shape of the bracket 6, so that the bracket 6 can be lifted on the arc surface of the lifting block 402, which facilitates the initial lifting and fixing of the bracket 6.
[0026] In this embodiment of the invention, the shape of the stabilizing groove 305 is adapted to the shape of the stabilizing ring 306. Two stabilizing rings 306 are provided, and they are fixedly installed on the arc surface of the bracket 6 in a linear array. This allows the stabilizing rings 306 to engage with the inside of the stabilizing groove 305, facilitating the fixation of the bracket 6. A through hole is provided on the surface of the locking block 5, the diameter of which is adapted to the diameter of the threaded rod 302. The threaded rod 302 penetrates the surface of the locking block 5, and under the action of the threaded rod 302 and the nut 303, locks the two rings. Block 5 is fixed, and the shape of the mounting block 301 is adapted to the shape of the sliding groove 2, so that the mounting block 301 can slide inside the sliding groove 2. The side wall of the locking block 5 is provided with a groove adapted to the bracket 6, so that the bracket 6 can be fixedly installed inside the locking block 5. The surface of the mounting block 301 is provided with a mounting hole and the sliding groove 2 inside the base 1 is provided with a threaded hole, so that the bolt can pass through the arc surface of the mounting block 301 and thus conveniently fix the mounting block 301 to the surface of the base 1. The surface of the base 1 is fixed to the ground by bolts.
[0027] In this utility model, during use, the bracket 6 is initially placed on the upper surface of the stabilizing block 304, and then the two locking blocks 5 are moved. The stabilizing ring 306 on the bracket 6 is engaged with the arc surface of the locking block 5, thereby increasing the contact area between the bracket 6 and the locking block 5 and ensuring the stability of the bracket 6. Next, the threaded rod 302 locks the two locking blocks 5 together with the nut 303. Finally, the mounting block 301 is fixedly installed on the upper surface of the base 1 with bolts.
[0028] Furthermore, the lifting block 402 on the stabilizing block 304 continues to lift the arc surface of the bracket 6, while the limiting block 403 limits the position of the bracket 6, ensuring that the position of the bracket 6 is convenient for the stabilizing ring 306 to be snapped into the inside of the stabilizing groove 305 for easy fixation of the bracket 6.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
