Description

Technical Field

[0001] The present application relates to the technical field of guiding shoes, and in particular to an assembled shearer guiding shoe. Background Art

[0002] A shearer is a coal mining machine that, in a longwall coal mining face, breaks coal from the coal body with a working mechanism (coal breaking) and loads it into the face conveyor (coal loading). The shearer travels at a set traction speed (traction) so that the coal breaking and coal loading processes can be carried out continuously.

[0003] The shearer guiding shoe refers to a part that plays a guiding and supporting role during the operation of the shearer. It is located at the front of the shearer power head, directly contacts the coal wall, can withstand the force from the coal wall, and ensures the normal operation of the shearer. The correct operation of the guiding shoe plays a very important role in improving coal mining efficiency and extending the life of the shearer. When the shearer is working, the shearer reciprocates on the track, causing friction between the guiding shoe and the track. When the wear amount of the guiding shoe reaches a certain level, the guiding shoe needs to be replaced.

[0004] Traditional guiding shoes are usually integral. When replacing, the entire guiding shoe needs to be removed from the axle of the shearer traveling component. However, the axle and the housing are in a tight fit, which increases the workload of disassembly and maintenance, and the worn parts removed can only be discarded as a whole, increasing the usage cost. Utility Model Content

[0005] In order to solve the above problems, the present application provides an assembled shearer guiding shoe.

[0006] The assembled shearer guiding shoe provided by the present application adopts the following technical solutions:

[0007] An assembled shearer guiding shoe includes: a guiding shoe main body, two wear-resistant plates installed in the guiding shoe main body, and two outer baffles installed at both ends of the guiding shoe main body and used to block the wear-resistant plates; an inner sliding groove for the wear-resistant plates to slide and insert is provided in the guiding shoe main body, a number of fixing holes are provided between the two ends of the guiding shoe main body and in the outer baffles, and bolts are fixedly installed between the fixing holes of the guiding shoe main body and the outer baffles;

[0008] A material pushing mechanism is provided in the outer baffle, and the material pushing mechanism includes a scraper fixedly provided in the outer baffle and a triangular plate movably provided on one side of the scraper for pushing the coal material on the shearer track away when the guiding shoe moves.

[0009] By adopting the above technical solution, the guide shoe is assembled as a whole by sliding the wear-resistant plate into the main body of the guide shoe and installing the outer baffle plates at both ends of the guide shoe with bolts. During maintenance, the maintenance personnel only need to dismantle, replace and discard the easily worn wear-resistant plates separately, without having to replace and discard the entire guide shoe, thereby reducing the workload of disassembly and maintenance.

[0010] Preferably, a limiting groove is provided on the side of the scraper away from the guide shoe body, a limiting plate is fixedly provided on one side of the triangular plate and abuts against the limiting groove, a return spring for pressing down the limiting plate is fixedly provided on the top of the limiting groove of the scraper, a positioning rod is fixedly provided on the bottom of the limiting groove of the scraper, a positioning hole is provided in the limiting plate, and the top end of the positioning rod is fitted into the positioning hole of the limiting plate.

[0011] By adopting the above technical solution, the triangular plate can push the coal on the top of the coal mining machine track when the guide sliding shoe moves, and the positioning rod inserted into the positioning hole can limit the limit plate, so that the limit plate and the triangular plate can only be raised and lowered, so that the triangular plate can always be against the coal mining machine track under the elastic force of the reset spring, avoiding the triangular plate from being unable to continue pushing materials due to wear and tear and gaps between the triangular plate and the track.

[0012] Preferably, a groove is provided on the side of the scraper away from the limiting groove, and a plurality of rollers for supporting against the coal mining machine track are rotatably connected in the groove of the scraper.

[0013] By adopting the above technical solution, the roller can increase the wear of the scraper when it moves by rotating.

[0014] Preferably, a guard plate for protecting the roller is fixedly provided at the opening of the groove of the scraper, and a plurality of bristles for supporting against the coal mining machine track are fixedly provided at the bottom of the guard plate.

[0015] By adopting the above technical solution, the bristles can brush away part of the coal dust on the coal mining machine track when the guide sliding shoe moves in the reverse direction, thereby improving the cleanliness of the track.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. The guide shoe is assembled as a whole by sliding the wear-resistant plate into the main body of the guide shoe and installing the outer baffles at both ends of the guide shoe with bolts. This is convenient and quick. During maintenance, maintenance personnel only need to remove, replace and discard the easily worn wear-resistant plates separately, without having to replace and discard the entire guide shoe. This reduces the workload of disassembly and maintenance and reduces the cost of use, thereby simplifying the guide shoe disassembly and assembly process, saving maintenance time and alleviating the workload of maintenance personnel.

[0018] 2. By setting the scraper plate and the triangular plate, the coal material on the top of the shearer track can be pushed away when the guiding sliding shoe moves, preventing the coal material on the top of the track from easily entering the guiding sliding shoe and being compacted, which may cause the guiding sliding shoe to get stuck. This ensures the normal operation of the guiding sliding shoe. Under the elastic force of the return spring, the triangular plate can always abut against the track, avoiding the gap between the triangular plate and the track due to wear, which may prevent the triangular plate from pushing the material continuously. This extends the service life of the triangular plate. Moreover, by pulling the limiting plate upward from the positioning insertion rod, the limiting plate and the triangular plate can be removed as a whole for replacement, which is convenient for maintenance.

Detailed Description of the Embodiment

[0024] The following will Figures 1 - 4 further describe the present application in detail with reference to the attached drawings.

[0025] An embodiment of the present application discloses an assembled shearer guiding sliding shoe.

[0026] An assembled shearer guiding sliding shoe, referring to Figures 1 - 2 , includes: a guiding sliding shoe body 1, two wear-resistant plates 11 and two outer baffles 12. Among them, the two wear-resistant plates 11 include a left wear-resistant plate 11 and a right wear-resistant plate 11, and the two outer baffles 12 include a left outer baffle 12 and a right outer baffle 12. The guiding sliding shoe is composed of the above five parts. The easily worn parts on the inner side of the guiding sliding shoe are independently designed as the left and right wear-resistant plates 11 for separate production and assembly use.

[0027] Referring to Figures 1 - 2, two wear-resistant plates 11 are installed in the guiding slide shoe body 1. The two wear-resistant plates 11 are installed at both ends of the guiding slide shoe body 1 and are used to block the wear-resistant plates 11. An inner sliding groove 13 for the wear-resistant plates 11 to slide and insert is provided in the guiding slide shoe body 1. A number of fixing holes 14 are provided in both ends of the guiding slide shoe body 1 and in the outer baffle 12. Bolts are fixedly installed between the fixing holes 14 of the guiding slide shoe body 1 and the outer baffle 12. The guiding slide shoe body 1 can guide, support and limit the wear-resistant plates 11 through the inner sliding groove 13, and the bolts can connect the guiding slide shoe body 1 and the outer baffle 12, so that the two outer baffles 12 can block, limit and fix the wear-resistant plates 11 in the guiding slide shoe body 1.

[0028] During the installation operation, the left and right wear-resistant plates 11 need to be assembled first, pushed into the inner sliding groove 13 of the guiding slide shoe body 1, then the left and right outer baffles 12 are placed at both ends of the guiding slide shoe body 1, and the fixing holes 14 of the guiding slide shoe body 1 and the outer baffle 12 are connected by bolts to connect and fix the guiding slide shoe body 1 and the outer baffle 12, so as to complete the overall assembly of the guiding slide shoe.

[0029] Refer to Figure 1 and Figure 3 , a coal pushing mechanism is provided in the outer baffle 12. The coal pushing mechanism includes a scraper 2 fixedly provided in the outer baffle 12 and a triangular plate 3 movably provided on one side of the scraper 2 for pushing the coal on the shearer track away when the guiding slide shoe moves. The scraper 2 can connect the outer baffle 12 and the triangular plate 3. When the guiding slide shoe moves, the triangular plate 3 that moves along with it can push the coal falling on the top of the track during the coal mining process, and under the guidance of the inclined surfaces on both sides of the triangular plate 3, the pushed coal is guided and pushed to both sides of the track, so as to push the coal away, so that the coal on the top of the track is not easy to enter the guiding slide shoe and be compacted to jam the guiding slide shoe.

[0030] Refer to Figure 3 and Figure 4 , a limiting groove 21 is provided on the side of the scraper 2 facing away from the guiding slide shoe body 1. A limiting plate 31 is fixedly provided on one side of the triangular plate 3 and is fitted and abutted in the limiting groove 21. A return spring 32 for pressing down the limiting plate 31 is fixedly provided at the top of the limiting groove 21 of the scraper 2. The return spring 32 is fitted and abutted against the top of the limiting plate 31, and the limiting groove 21 can limit the limiting plate 31.

[0031] Refer to Figure 3 and Figure 4The top of the positioning rod 34 is fitted into the positioning hole 33 of the limiting plate 31 , and the positioning rod 34 inserted into the positioning hole 33 can limit the limiting plate 31 so that the limiting plate 31 and the triangular plate 3 can only be lifted and lowered, so that the triangular plate 3 can always be against the coal mining machine track under the elastic force of the reset spring 32, so as to avoid the triangular plate 3 from being unable to continue pushing materials due to wear and tear and gaps between the triangular plate 3 and the track. The staff can pull the limiting plate 31 upwards away from the positioning rod 34, and then remove the limiting plate 31 and the triangular plate 3 as a whole for replacement.

[0032] Reference Figure 3 and Figure 4 A groove 22 is provided on the side of the scraper 2 away from the limit groove 21, and a number of rollers 4 for resting on the coal mining machine track are rotatably connected in the groove 22 of the scraper 2. A guard plate 5 for protecting the roller 4 is fixed at the opening of the groove 22 of the scraper 2, and a number of brushes 51 for resting on the coal mining machine track are fixed at the bottom of the guard plate 5. The scraper 2 can accommodate the roller 4 through the groove 22, and the roller 4 can reduce the wear of the scraper 2 when moving by rotating. The guard plate 5 can partially block and protect the roller 4, and the bristles 51 can brush off part of the coal dust on the coal mining machine track when the guide shoe moves in the opposite direction, thereby improving the cleanliness of the track.

[0033] The implementation principle of an assembled coal mining machine guide shoe in the embodiment of the present application is as follows:

[0034] During installation, first assemble the left and right wear-resistant plates 11 and push them into the inner grooves 13 of the guide shoe body 1. Then, place the left and right outer baffles 12 at both ends of the guide shoe body 1. Bolts are used to connect the fixing holes 14 of the guide shoe body 1 and the outer baffles 12 to connect and fix the guide shoe body 1 and the outer baffles 12, thus completing the assembly of the entire guide shoe.

[0035] During the underground replacement process, the assembled guide shoe can be replaced by unscrewing the bolts on the side in the direction of movement of the guide shoe, and then removing the outer baffle 12 to replace the worn wear-resistant plate 11. During maintenance, the maintenance personnel only need to dismantle, replace and discard the easily worn wear-resistant plate 11 separately, without having to replace and discard the entire guide shoe, which reduces the workload of disassembly and maintenance and reduces the cost of use, thereby simplifying the guide shoe disassembly and assembly process, saving maintenance time and alleviating the workload of maintenance personnel;

[0036] When the guide shoe moves, the triangular plate 3 that moves with it can push the coal that falls to the top of the track during the coal mining process, and under the guidance of the inclined surfaces on both sides of the triangular plate 3, the pushed coal is guided and pushed to both sides of the track, thereby pushing the coal away, making it difficult for the coal on the top of the track to enter the guide shoe and be compacted, thereby causing the guide shoe to be stuck;

[0037] And under the elastic force of the return spring 32, the triangular plate 3 can always be abutted against the shearer track, so as to prevent the triangular plate 3 from having a gap with the track due to wear and being unable to continue pushing materials. Moreover, the staff can pull the limit plate 31 upward to disengage from the positioning plug 34, and then the limit plate 31 and the triangular plate 3 as a whole can be removed and replaced.

[0038] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
