Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing equipment, in particular to a tongue plate grinding tool for a scraper conveyor. Background Art

[0002] With the development of society and technology, equipment in various fields has been greatly improved. Scraper conveyor is an important transportation equipment in coal mine production. It is a conveyor that uses scraper chain to transport bulk materials in the trough. The main components include: head frame, chain, reducer, tongue plate, motor, etc. In order to ensure the subsequent installation efficiency and movement efficiency of the tongue plate, it is generally polished and polished with grinding tooling after production is completed, which can greatly improve work efficiency.

[0003] After retrieval, the publication number CN212287025U, application date 2020.08.04 discloses a multifunctional metal plate grinding device. During use, the plate to be polished is placed on the active roller and the driven roller, and the motor drives the active roller to rotate through the active wheel and the transmission belt, so that the plate to be polished moves forward. During this process, the side polishing motor drives the side polishing grinding wheel to rotate to deburr and polish both sides of the plate. At the same time, the upper polishing motor drives the upper polishing grinding wheel to rotate to polish the upper surface of the plate to be polished. During the process of polishing the upper surface of the plate by the upper polishing grinding wheel, the cylinder can drive the motor fixed slide to slide along the slide groove, so that the upper polishing grinding wheel can reciprocate perpendicular to the movement direction of the plate, thereby improving the efficiency of grinding and polishing the upper surface of the plate.

[0004] However, it still has the following disadvantages in actual use:

[0005] The above-mentioned multifunctional metal plate grinding device grinds the surface of the metal plate through the upper polishing device when in use. However, after the single-side grinding of the metal plate is completed, the metal plate needs to be manually turned over to grind the other side, which affects the grinding efficiency and effect of the metal plate and has low work efficiency.

[0006] 2. The above multifunctional metal plate grinding device lacks protective measures for surrounding workers during the metal plate grinding process, which poses a safety hazard. To this end, we provide a scraper conveyor tongue plate grinding tool to solve the above problems. Utility Model Content

[0034] Furthermore, the conveying roller 101 is a prior art, so it will not be described in detail here. The side grinding mechanism 102 and the top grinding mechanism 106 are both prior art, so they will not be described in detail here. The protective frame 105 can be pushed to move by the hydraulic cylinder 1031. The motor 201 can drive the threaded rod 2011 to rotate under the action of the coupling, and the outer wall of the threaded rod 2011 is respectively provided with positive threads and negative threads on both sides, wherein the positive threads and the negative threads are respectively connected to the threaded holes on the end faces of the right moving block 202 and the left moving block 203. The internal thread in the wall is meshed and connected, so when the threaded rod 2011 rotates, it will drive the right moving block 202 and the left moving block 203 to move in opposite directions. The right moving block 202 and the right flap 205 are movably connected by the connecting rod 204, and the left moving block 203 and the left flap 206 are movably connected by the connecting rod 204. When the right moving block 202 and the left moving block 203 move, the right flap 205 and the left flap 206 are flipped under the action of the connecting rod 204, thereby achieving the effect of flipping the tongue plate.

[0035] The operation process of this embodiment is as follows: first, the tongue plate to be polished is placed on the surface of the right flap 205 in the processing table 104, and then the processing table 104 can be transported to the bottom of the top polishing mechanism 106 under the action of the conveying roller 101, and the hydraulic cylinder 1031 is started to push the top polishing mechanism 106 to move downward, and the top polishing mechanism 106 is used to polish the upper surface of the tongue plate, and after the upper surface of the tongue plate is polished, the motor 201 is started, and the output shaft of the motor 201 rotates to drive the threaded rod 2011 to rotate under the action of the coupling, and the external thread on the outer wall of the threaded rod 2011 is meshed with the internal thread in the wall of the threaded hole on one side end face of the right moving block 202 and the left moving block 203.

Therefore, when the right moving block 202 and the left moving block 203 move, the outer ends of the right flap 205 and the left flap 206 on both sides will be driven upward through the connecting rod 204, so that the outer ends of the right flap 205 and the left flap 206 can be lifted up, and the tongue plate placed on the surface of the right flap 205 can be flipped to the surface of the left flap 206, and then the right flap 205 and the left flap 206 are moved to a horizontal state, and the top grinding mechanism 106 is used to grind the surface of the tongue plate after it is flipped, thereby greatly improving the grinding efficiency and effect of the tongue plate, and the work efficiency is high. Specific embodiment 2

[0036] See also Figure 1 , 5 On the basis of the specific embodiment 1, what is different from the first embodiment is that: a protective component 3 is provided, and the protective component 3 includes a pressing plate 301 and an extension plate 302 fixedly connected to the center position of its upper surface, which solves the problem that the existing multifunctional metal plate grinding device lacks protection measures for surrounding workers during the metal plate grinding process, and there are safety hazards.

[0037] Specifically, the top of the extension plate 302 passes through the sliding hole at the bottom of the buffer groove 1051 and is connected to the limit plate 303. Springs 304 are evenly spaced on the top of the limit plate 303. The springs 304 are located between the inner bottom end of the buffer groove 1051 and the limit plate 303.

[0038] Furthermore, the extension plate 302 and the protection frame 105 play a protective role. Under the elastic performance of the spring 304, the length and setting range of the extension plate 302 can be adjusted, and the safety performance is high.

[0039] The operation process of this embodiment is as follows: during the grinding process of the tongue plate, the hydraulic cylinder 1031 is started to push the protective frame 105 downward. The downward movement of the protective frame 105 will drive the pressure plate 301 at the bottom thereof to move downward, and during the downward movement, the bottom of the pressure plate 301 contacts the surface of the processing table 104, and the top of the pressure plate 301 is connected to the limit plate 303 through the extension plate 302. Therefore, the pressure plate 301 will move upward under the force, and the limit plate 303 will be pushed to move under the action of the extension plate 302, and at the same time, the spring 304 will be squeezed, and the top grinding mechanism 106 will contact the surface of the tongue plate for grinding. During the grinding process, the protective frame 105 and the extension plate 302 will cover the outside of the inner grinding part to play a protective role, with high safety performance.
