TECHNICAL FIELD

[0001] The utility model relates to a pipe belt conveyor head unwinding and belt pressing device. BACKGROUND

[0002] In the process of coal mining, pipe belt conveyors are needed for conveying. The main feature of the pipe belt conveyor is that the conveying belt is wound into a pipe shape, so that the material is conveyed in a closed pipe structure. This design not only realizes the closed conveying of the material, avoids the flying and scattering of the material, but also significantly improves the conveying efficiency and reduces the energy consumption.

[0003] The existing device has some drawbacks in use, for example: when the pipe belt conveyor is transporting, the pipe belt may deviate in the unwinding section, causing friction with the main frame above the pipe belt, resulting in smoke at the edge of the pipe belt, and even tearing of the pipe belt. UTILITY MODEL CONTENT

[0004] The utility model aims to provide a pipe belt conveyor head unwinding and belt pressing device, which solves the problem of friction between the pipe belt and the main frame above the pipe belt when the pipe belt deviates.

[0005] The utility model provides the following technical scheme: a pipe belt conveyor head unwinding and belt pressing device, comprising a main frame, the lower end surface of the main frame is fixedly connected with a mounting bracket, two roller supports are arranged on one side of the mounting bracket, the outer walls of the two roller supports away from the mounting bracket are fixedly connected with mounting plates, the two mounting plates are symmetrically arranged, the outer walls of the two mounting plates opposite to each other are fixedly connected with reinforcing plates, the side of the two reinforcing plates close to the mounting bracket is fixedly connected with the mounting bracket, the inner walls of the two mounting plates opposite to each other at the top are vertically provided with mounting grooves, the inner sides of the two mounting grooves are slidably connected with mounting blocks, a roller is rotatably connected between the two mounting blocks, and a dismounting assembly for quickly dismounting the roller is arranged on the two mounting plates.

[0006] In the above scheme, when the pipe belt deviates, the roller is pressed against the pipe belt, so that the pipe belt no longer rubs against the main frame, the pipe belt wear or tearing phenomenon is eliminated, the service life of the pipe belt is prolonged, safety is ensured, efficient operation is achieved, and the roller can be conveniently dismounted through the dismounting assembly for subsequent maintenance and replacement.

[0007] As a preferred embodiment of the above technical scheme, four first mounting holes are arranged in a rectangular array on the two roller supports, second mounting holes are arranged on the mounting bracket corresponding to the positions of the first mounting holes, bolts are arranged on the inner sides of the same group of first mounting holes and second mounting holes, and nuts are threadedly connected to the outer sides of the bolts.

[0008] In the above scheme, through the cooperation of the bolt and the nut, strong clamping force can be formed to firmly fix the carrier roller support on the mounting rack, and the connecting mode is not only simple and reliable, but also has high connecting strength and can bear large load.

[0009] As a preferred form of the above technical solution, the opposite inner side walls of the two mounting grooves are vertically provided with first limiting grooves, and the opposite outer walls of the two mounting blocks are fixedly connected with first limiting blocks matched with the size of the first limiting grooves, and the two mounting blocks are respectively connected with the mounting plate through the corresponding first limiting blocks.

[0010] In the above scheme, the cooperation of the first limiting groove and the first limiting block provides accurate guidance for the sliding of the mounting block in the mounting groove, and this design ensures that the mounting block will not deviate from the predetermined trajectory during installation, thereby improving the installation accuracy of the carrier roller.

[0011] As a preferred form of the above technical solution, the dismounting assembly comprises moving grooves respectively provided in the inner walls of the two mounting grooves, two moving blocks are slidably connected in the inner sides of the two moving grooves, and the same group of two moving blocks are symmetrically arranged, the opposite outer walls of the top of the same group of two moving blocks are fixedly connected with clamping blocks, the opposite outer walls of the same group of two moving blocks are fixedly connected with slide rods, the ends of the same group of two slide rods away from the moving blocks are transversely penetrated through the opposite outer walls of the corresponding mounting plates and are slidably connected with the opposite outer walls of the corresponding mounting plates, and the ends of the slide rods away from the moving blocks are fixedly connected with buttons.

[0012] In the above scheme, the slide rods are pushed by pressing the buttons, and then the moving blocks and the clamping blocks are moved to release the clamping structure, and this design simplifies the release operation of the dismounting assembly and improves the work efficiency.

[0014] In the above scheme, when external force acts on the moving block to make the clamping block disengage from the clamping groove, the spring can use its elastic potential to push the moving block back to its original position, ensuring that the clamping block can quickly return to the initial position after release, and preparing for the next clamping operation.

[0015] As the preferred of the above technical scheme, two opposite side inner walls of the moving groove are provided with second limiting grooves, and two opposite side outer walls of the moving block are fixedly connected with second limiting blocks matched with the size of the second limiting grooves, and the moving block is slidably connected with the mounting plate through the corresponding second limiting block.

[0016] In the above scheme, the cooperation of the second limiting block and the second limiting groove ensures that the moving block can only slide along the predetermined track, prevents the moving block from deviating during sliding, and thus ensures the stability of the disassembly assembly.

[0017] As the preferred of the above technical scheme, the end of the clamping block away from the moving groove is provided with an arc surface.

[0018] In the above scheme, the arc surface has a natural guiding effect, when the clamping block and the moving block are clamped into the connecting groove, the arc surface can gradually contact the edge of the connecting groove and guide the clamping block to gradually clamp into the connecting groove along the shape of the connecting groove.

[0019] Compared with the prior art, the utility model has the advantages that:

[0020] In the utility model, when the belt deviates, the belt is resisted by the carrier roller, the carrier roller avoids the direct contact between the edge of the belt and the main frame, eliminates the belt wear or tearing phenomenon, prolongs the service life of the belt, ensures the safety, and achieves the high -efficient operation.

[0029] As an embodiment in the embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the inner side wall of the two installation grooves 15 is vertically provided with a first limiting groove 30, and the outer wall of the two installation blocks 16 is fixedly connected with a first limiting block 31 matched with the size of the first limiting groove 30. The two installation blocks 16 are slidably connected with the installation plate 13 through the corresponding first limiting block 31. In the specific use process, the cooperation of the first limiting groove 30 and the first limiting block 31 provides accurate guidance for the sliding of the installation block 16 in the installation groove 15. This design ensures that the installation block 16 will not deviate from the predetermined trajectory during installation, thereby improving the installation accuracy of the carrier roller 17.

[0030] As an embodiment in this embodiment, as shown in Figure 3 and Figure 4 As shown, the disassembly assembly 4 includes a moving groove 401 respectively provided in the inner wall of the two installation grooves 15, and the inner side of the two moving grooves 401 is slidably connected with two moving blocks 402.

The outer wall of the opposite side of the same group of two moving blocks 402 is fixedly connected with a slide rod 404, and the end of the same group of two slide rods 404 away from the moving block 402 is transversely connected with the opposite outer wall of the corresponding installation plate 13 and slidably connected with the opposite outer wall of the corresponding installation plate 13.

With the pushing of the installation block 16, the moving block 402 and the clamping block 403 will slide in the connecting groove 408. The end of the clamping block 403 is provided as an arc surface, which helps the clamping block 403 and the moving block 402 to be more smoothly clamped into the connecting groove 408. The spring 407 will be compressed when the moving block 402 is clamped into the connecting groove 408, and the elastic potential energy is stored.

[0032] Working principle: the carrier roller 17 is rotationally connected between the two installation blocks 16, and then the installation blocks 16 are pushed into the installation grooves 15. The cooperation between the first limiting grooves 30 and the first limiting blocks 31 ensures that the installation blocks 16 will not deviate from the predetermined track during the installation process. With the pushing of the installation blocks 16, the mobile blocks 402 and the clamping blocks 403 will slide in the connecting grooves 408. The clamping blocks 403 are provided with an arc-shaped surface at one end, so that the clamping blocks 403 and the mobile blocks 402 are more smoothly clamped into the connecting grooves 408. The springs 407 will be compressed when the mobile blocks 402 are clamped into the connecting grooves 408, and the elastic potential energy is stored. When the clamping blocks 403 slide to the position of the clamping grooves 409, the clamping blocks 403 will be pushed into the clamping grooves 409 due to the elastic force of the springs 407, realizing the fixation of the installation blocks 16. The carrier roller support 12 is placed at the designated position, the bolts 22 are respectively threaded through the first installation holes 20 on the carrier roller support 12 and the second installation holes 21 on the installation frame 11, and the bolts 22 are tightened, ensuring that the carrier roller support 12 is fifty millimeters lower than the main frame 10. When it is necessary to disassemble the carrier roller 17 for replacement, the button 405 is pressed to make the sliding rod drive the mobile blocks 402 to slide in the moving grooves 401. The cooperation between the second limiting blocks 51 and the second limiting grooves 50 ensures that the mobile blocks 402 can only slide along the predetermined track, preventing the mobile blocks 402 from deviating during the sliding process. With the sliding of the mobile blocks 402, the clamping blocks 403 will gradually separate from the clamping grooves 409. After the clamping blocks 403 completely separate from the clamping grooves 409, the installation blocks 16 can be easily taken out of the installation grooves 15, so as to replace the carrier roller 17 on the installation blocks 16.
