Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and particularly to a coal mine belt conveyor facilitating belt replacement and a method for replacing the same. Background Art

[0002] A belt conveyor, also known as a tape conveyor, is widely used in equipment for moving and conveying items. It has strong conveying capacity, long conveying distance, simple structure and easy maintenance, can be conveniently programmed and automatically operated, and conveys items by the continuous or intermittent movement of a conveyor belt. It runs at high speed, smoothly, with low noise, and can convey uphill and downhill. The belt conveyor is also the main equipment in the coal conveying system, facilitating the transfer of coal materials.

[0003] When the belt on the conveyor is damaged, the belt needs to be replaced. In the traditional method of replacing the belt, after the belt is disassembled, most of the time, the belt is pulled to separate it from the conveyor, which is not convenient for winding up the belt, resulting in a large floor area and difficult storage. At the same time, when installing a new belt, due to the heavy belt and long conveyor, it is very difficult for manpower to directly place the belt on the conveyor. Most of the time, ropes are wound around the conveyor, and then pulled by manual or vehicle traction tools to lift and lay the belt. Such back-and-forth operations are time-consuming and laborious, and improper operation is likely to cause belt damage. Summary of the Invention

[0026] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] Specifically, as Figure 1 , Figure 2 and Figure 6 shown, the conveying mechanism 2 includes a connecting seat 202. A plurality of symmetrically distributed connecting seats 202 are installed on the frame 1. Roller shafts 203 are respectively rotatably connected between the plurality of connecting seats 202.

Through the cooperation of the connecting seats 202, the installation of the plurality of roller shafts 203 is realized. Through the cooperation of the plurality of roller shafts 203, the tape is wound and connected, so that the tape is stably installed on the frame 1. At the same time, a plurality of roller shafts 203 with different angles are installed to support and resist the tape, so that the tape is stably supported. Under the cooperation of the driving assembly 201, the driving control of the roller shaft 203 and the tape is realized, and then the material is lifted and conveyed.

[0029] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the support mechanism 4 includes a cross plate 401. The cross plate 401 is installed at the bottom of the frame 1. Two parallel support plates 402 are respectively installed on the top sides of both ends of the cross plate 401. The support plates 402 are perpendicular to the cross plate 401. Connecting rods 403 are respectively installed at one ends of the two support plates 402. Fixed sleeves 405 are respectively snap-connected to one ends of the two connecting rods 403. Through the installation of the cross plate 401, it is beneficial to connect the two support plates 402, and then the installation of the two connecting rods 403 is realized. Through the snap connection of the two fixed sleeves 405, it is convenient to rotatably connect the winding shaft 601 subsequently to realize tape winding. Through the disassembly and assembly of the fixed sleeve 405, the disassembly and assembly of the winding shaft 601 are realized, and the operation is more convenient.

[0030] Specifically, as Figure 3 , Figure 4 and Figure 7As shown, at one end of the side walls of the two fixing sleeves 405, fixing holes 409 are respectively provided. One end of each of the two connecting rods 403 is respectively slidably connected with a latch 408. The bottom of the latch 408 extends to the inside of the fixing hole 409. At both ends of the bottom of the cross plate 401, supporting seats 404 are respectively vertically connected. The supporting seat 404 is in a "convex" shape structure. Through the opening of the fixing hole 409, it is beneficial to latch the inserted latch 408, so that the connection between the fixing sleeve 405 and the connecting rod 403 is firm and stable. By pulling out the latch 408, the latch 408 is separated from the fixing hole 409, which is convenient for disassembling the fixing sleeve 405. Through the installation of the supporting seat 404, the bottom of the cross plate 401 is supported, so that the support plate 402 has a certain height, which is convenient for winding the tape.

[0031] Specifically, as Figure 4 shown, the other ends of the two connecting rods 403 respectively extend to the inside of the two support plates 402. At the other ends of the two connecting rods 403, telescopic springs 406 are respectively installed. One end of the telescopic spring 406 is connected to the inside of the support plate 402. The connecting rod 403 is slidably connected to the inside of the support plate 402 through the telescopic spring 406. Through the installation of the telescopic spring 406, the connecting rod 403 and the support plate 402 can be telescopically slid, which is convenient for winding tapes of different thicknesses.

[0032] Specifically, as Figure 4 、 Figure 5 and Figure 8 shown, inside the two fixing sleeves 405, rotating sleeves 407 are respectively rotatably connected. The inner side of the rotating sleeve 407 is in a hexagonal structure. Through the installation of the rotating sleeve 407, it is beneficial to connect to both ends of the winding shaft 601 later, so that the winding shaft 601 can rotate smoothly, and then the tape winding work can be carried out.

[0033] Specifically, as Figure 2 、 Figure 3 and Figure 5 shown, the winding mechanism 6 includes a winding shaft 601. A winding shaft 601 is provided between the two fixing sleeves 405. Both ends of the winding shaft 601 are in a hexagonal structure. Both ends of the winding shaft 601 are slidably connected to the inside of the two rotating sleeves 407. A connecting groove 605 is provided on the winding shaft 601. Through the installation of the winding shaft 601, it is beneficial for the tape winding work. And through the opening of the connecting groove 605, one end of the tape is inserted and latched, so as to achieve better winding. After disassembling the fixing sleeve 405, the rotating sleeve 407 is separated from the winding shaft 601, so as to disassemble and recycle the wound tape.

[0034] Specifically, as Figure 5As shown, the top side of the winding shaft 601 is vertically threaded with multiple equidistantly distributed bolts 606, and multiple of the bolts 606 extend to the inside of the connecting groove 605. Turntables 602 are respectively installed at both ends of the winding shaft 601. Through the installation of the bolts 606, the tape inserted into the connecting groove 605 is resisted and fixed to prevent it from falling off. Through the installation of the turntable 602, it plays a positioning role, so that the wound tape will not be wound up and deviated, and remain at the center of the winding shaft 601.

[0035] Specifically, Figure 3 and Figure 5 As shown, a slot 604 is provided at the center of one end of the reeling shaft 601, and the slot 604 is a hexagonal structure. A crank 603 is snap-connected to the reeling shaft 601, and one end of the crank 603 is a hexagonal structure. One end of the crank 603 is snap-connected with the inside of the slot 604. The opening of the slot 604 facilitates the detachable connection between the crank 603 and the reeling shaft 601, thereby realizing the drive control of the reeling shaft 601 and performing the tape reeling operation.

[0036] Specifically, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the transmission mechanism 3 includes a slot 301, wherein the slots 301 are respectively provided at the edges of the side walls of the two ends of the two rollers 203, and two cables 302 are provided between the two rollers 203. The two cables 302 are respectively connected to the rollers 203 through the slots 301, and a plurality of equidistant connecting belts 303 are connected to the two cables 302. By opening the slots 301, the cables 302 are connected to the two rollers 203, so that the cables 302 can be driven and controlled when the rollers 203 rotate, and through the cooperation of the connecting belts 303, the connection of the two sides of one end of the tape to be installed is realized, so that the cables 302 drive one end of the tape, and then the rolled tape is installed on the frame 1.

[0037] Specifically, Figure 6As shown, the rotating mechanism 5 includes a connecting block 501. The connecting block 501 is respectively installed on the top sides of both ends of the cross plate 401. The two support plates 402 are rotatably connected to the two connecting blocks 501 through a rotating shaft 504. The support plate 402 is rotatably connected to the cross plate 401 through the connecting block 501. Symmetrically distributed support plates 502 are installed on the side walls of both ends of the cross plate 401. The support plate 502 is of an "L" - shaped structure. A magnetic block 503 is installed on the top side of one end of the support plate 502. The bottom of the support plate 402 abuts against the magnetic block 503. Through the installation of the connecting block 501, the support plate 402 can rotate, unfold, and be stored in a folded state. Through the installation of the support plate 502, the support plate 402 can be supported when it is in a folded state or after folding. With the cooperation of the magnetic block 503, the support plate 402 is firmly and stably adsorbed, and the support plate 402 will not loosen.

[0038] Specifically, as Figure 7 , Figure 8 , Figure 9 shown, the protection mechanism 7 includes a toothed ring 702. The toothed ring 702 is fixedly connected to the two rotating sleeves 407 respectively. The toothed ring 702 is rotatably connected to the inner side of the fixed sleeve 405 through the rotating sleeve 407. A clamping block 701 is installed inside one end of the fixed sleeve 405. The clamping block 701 is of a trapezoidal structure. One end of the clamping block 701 is slidably connected to the inner side of the fixed sleeve 405 through a resisting spring 704. The other end of the clamping block 701 abuts against the toothed ring 702. The pointed teeth on the toothed ring 702 are in the opposite direction to the pointed teeth at one end of the clamping block 701. Through the cooperation of the resisting spring 704, the clamping block 701 has telescopic sliding. Through the installation of the toothed ring 702, under the resistance of the resisting spring 704, the clamping block 701 remains in contact with the toothed ring 702. Since the pointed teeth on the toothed ring 702 are in the opposite direction to the pointed teeth at one end of the clamping block 701, the rotating sleeve 407 can drive the toothed ring 702 to rotate only in one direction and cannot rotate in the reverse direction. Thus, when the winding shaft 601 winds the tape, it will not reverse and loosen.

[0039] Specifically, as Figure 7 shown, two ejector rods 703 are vertically and threadedly connected to the top sides of one ends of the two fixed sleeves 405. The bottom of the ejector rod 703 is of a hemispherical structure. The bottom of the ejector rod 703 extends to the top side of one end of the clamping block 701. Through the installation of the ejector rod 703, it is beneficial to control the abutment of the clamping block 701, realizing that the clamping block 701 is abutted and contracted, so that the clamping block 701 is separated from the toothed ring 702, and then the rotating sleeve 407 can rotate freely, facilitating the rotation during the installation of a new tape later.

[0040] A method for replacing the tape of a coal mine belt conveyor that is convenient for tape replacement includes the following steps: S1: First, rotate and open the support mechanism 4 in cooperation with the rotating mechanism 5. Then, install the retracting mechanism 6 on the support mechanism 4. After removing the conveying mechanism 2, connect it to the retracting mechanism 6. S2: Then, rotate the retracting mechanism 6 to wind the tape around the retracting mechanism 6. When the winding is completed, control the disassembly of the support mechanism 4 to remove the retracting mechanism 6, and move and recycle the wound tape. S3: A protection mechanism 7 is installed inside the support mechanism 4, allowing one end of the support mechanism 4 to rotate unidirectionally. The retracting mechanism 6 can only wind the tape and will not loosen, making the operation convenient and safe. S4: Subsequently, move the retracting mechanism 6 wound with a new tape to the support mechanism 4 for installation. Then, connect the transmission mechanism 3 to both sides of one end of the tape. Under the rotation of the conveying mechanism 2, the transmission mechanism 3 drives the tape to move and lay on the frame 1, realizing the installation of the tape.

[0041] When the present invention is in use, first, through the cooperation of the connecting seat 202, the installation of multiple roller shafts 203 is realized. Through the cooperation of the multiple roller shafts 203, the winding connection of the tape is realized, so that the tape is stably installed on the rack 1. At the same time, multiple roller shafts 203 at different angles are installed to support and resist the tape, so that the tape is stably supported. Under the cooperation of the driving assembly 201, the driving control of the roller shaft 203 and the tape is realized, and then the material is lifted and conveyed. Through the installation of the cross plate 401, it is beneficial to connect the two support plates 402, and then the installation of the two connecting rods 403 is realized. Through the engagement of the two fixing sleeves 405, it is convenient to rotatably connect the winding shaft 601 subsequently, and the tape winding is realized. Through the disassembly and assembly of the fixing sleeve 405, the disassembly and assembly of the winding shaft 601 are realized, and the operation is more convenient. Through the opening of the fixing hole 409, it is beneficial to engage the inserted pin 408, so that the connection between the fixing sleeve 405 and the connecting rod 403 is firm and stable. By pulling out the pin 408, the pin 408 is separated from the fixing hole 409, which is convenient for disassembling the fixing sleeve 405. Through the installation of the support seat 404, the bottom of the cross plate 401 is supported, so that the support plate 402 has a certain height, which is convenient for tape winding. Through the installation of the telescopic spring 406, the connecting rod 403 and the support plate 402 can be telescopically slid, which is convenient for winding tapes of different thicknesses. Through the installation of the rotating sleeve 407, it is beneficial to connect with both ends of the winding shaft 601 subsequently, so that the winding shaft 601 rotates smoothly, and then the tape winding work is carried out. Through the installation of the winding shaft 601, it is beneficial for the tape winding work. And through the opening of the connecting groove 605, one end of the tape is inserted and engaged, so as to realize better winding. After disassembling the fixing sleeve 405, the rotating sleeve 407 is separated from the winding shaft 601, and the wound tape is disassembled and recycled. Through the installation of the bolt 606, the tape inserted into the connecting groove 605 is resisted and fixed, playing a role in preventing detachment. Through the installation of the turntable 602, a positioning role is played, so that the wound tape will not be wound offset and remains at the center of the winding shaft 601. Through the opening of the slot 604, it is beneficial for the crank 603 to be detachably connected to the winding shaft 601, so as to realize the driving control of the winding shaft 601 and carry out the tape winding operation. Through the installation of the connecting block 501, the support plate 402 can rotate, unfold and be shielded and stored. Through the installation of the support plate 502, the support plate 402 or the folded support plate 402 is lifted and supported. Under the cooperation of the magnetic block 503, the support plate 402 is firmly and stably adsorbed, and the support plate 402 will not loosen. Through the opening of the card slot 301, the cable 302 is connected to the two roller shafts 203, so that the cable 302 can be driven and controlled when the roller shaft 203 rotates. Through the cooperation of the connecting belt 303, the two sides of one end of the tape to be installed are connected, so that the cable 302 drives one end of the tape, and then the wound tape is installed on the rack 1. Through the cooperation of the resisting spring 704, the block 701 has telescopic sliding. Through the installation of the toothed ring 702, under the resistance of the resisting spring 704,The clamping block 701 remains in contact with the toothed ring 702. Since the pointed teeth on the toothed ring 702 are in the opposite direction to the pointed teeth at one end of the clamping block 701, the rotating sleeve 407 can only drive the toothed ring 702 to rotate in one direction and cannot rotate in the reverse direction. Thus, when the winding shaft 601 winds up the tape, it will not reverse and loosen. Through the installation of the ejector rod 703, it is beneficial to control the contact of the clamping block 701, enabling the clamping block 701 to be retracted by contact, so that the clamping block 701 is separated from the toothed ring 702, and then the rotating sleeve 407 can rotate freely, facilitating the rotation during the subsequent installation of a new tape.
