Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground fully mechanized mining faces and scraper conveyors, specifically a disassembly device for the chute insert plates of a scraper conveyor. Background Technology
[0002] In underground coal mine working faces, scraper conveyors and roadway equipment are usually arranged with open windows to observe and manage the operation of the bottom chain conveyor scraper. Most existing equipment uses split insert plates for the open window structure. This method is not only conducive to adapting to underground space but also beneficial to engineering design. However, with the gradual wear and deformation of the chute after mining and the compression of coal dust, manual prying is required when disassembling the insert plates. The process is time-consuming and labor-intensive, especially the insertion and extraction on the coal wall side, which is even more dangerous. Currently, there is no special tool to solve this problem. Therefore, it is imperative to design a mechanical device that facilitates the disassembly of chute insert plates. Summary of the Invention
[0003] The purpose of this utility model is to provide a disassembly device for the chute insert plate of a scraper conveyor, which solves the problem of difficulty in disassembling the chute insert plate during the inspection and maintenance of the bottom chain track of the chute.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A disassembly device for a scraper conveyor chute insert plate, characterized in that it includes a support frame, a jack, a protective frame, and fastening bolts; the support frame has a left-right symmetrical structure, with bolt holes provided on both ends of the protruding bosses, a square boss at the lower end, and a round hole and internal thread in the middle.
[0006] The protective frame is an I-beam structure with bolt holes on the top plate;
[0007] The jack is provided with external threads;
[0008] The square boss at the lower end of the support frame is inserted into the oblong hole of the chute insert plate, and the exposed end of the chute insert plate enters the protective frame. The support frame and the protective frame are connected by fastening bolts, and the jack is locked to the support frame by threads.
[0009] Furthermore, the square boss at the lower end of the support frame mates with the oblong hole in the chute insert plate, and the outer width of the square boss is less than the width of the oblong hole in the chute insert plate.
[0010] Furthermore, the internal thread of the support frame mates with the external thread of the jack.
[0011] The beneficial effects of this utility model are mainly reflected in the following aspects: the disassembly device has a simple structure, strong process feasibility, and is easy to mass-produce; the disassembly device has outstanding functions, is easy to operate, and has reliable practical application capabilities; the disassembly device is not only specialized but also widely adaptable, and can be applied to any chute insert plate structure similar to this utility model.

[0020] The technical solutions of the present utility model will be described in complete and clear form below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all of them.
[0021] This utility model provides a device for disassembling the chute insert plate of a scraper conveyor, such as... Figure 1 As shown, it includes a support frame 1, a jack 2, a protective frame 3, and fastening bolts 4; the square boss at the lower end of the support frame 1 is inserted into the elongated hole of the chute insert plate 5, the exposed end of the chute insert plate 5 enters the protective frame 3, the support frame 1 and the protective frame 3 are connected by fastening bolts 4, and the jack 2 and the support frame 1 are locked by threads.
[0022] like Figure 2 and Figure 3 As shown, the support frame 1 has a symmetrical structure, with bolt holes on the protruding bosses at both ends, a square boss at the bottom, and a round hole and internal thread in the middle.
[0023] like Figure 4 As shown, the protective frame 3 has an I-beam structure and bolt holes are provided on the upper plate.
[0024] like Figure 5 As shown, the chute plate 5 is provided with an elongated hole, and the square boss at the lower end of the support frame 1 is engaged with the elongated hole. The outer width L of the square boss is less than the width H of the elongated hole.
[0025] The implementation process of this utility model is as follows: After the disassembly device is fully installed, it is necessary to ensure that the support frame 1, the jack 2 and the chute have a certain distance M. In this embodiment, M is 10 mm. When it is necessary to disassemble the chute insert plate 5, adjust the extension of the jack 2. The horizontal thrust of the jack 2 acts on the chute, and the chute insert plate 5 moves in the opposite direction along with the main body of the disassembly device until it is dislodged.
[0026] It should be understood that the above detailed description of the technical solutions of this utility model with reference to preferred embodiments is illustrative and not restrictive. Those skilled in the art can modify the technical solutions described in the embodiments or make equivalent substitutions for some of the technical features based on reading this utility model specification. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
