[0002] Belt conveyors are common equipment in industrial enterprises, primarily used for transporting materials in production processes. They are an indispensable part of industrial plants, especially raw material yards. Over long-term use, belt conveyors inevitably encounter damage and aging, requiring timely belt replacement. Currently, the mainstream method is to use cranes, winches, and other mechanical equipment to pull out the old belt and install the new one. However, this method is labor-intensive, costly, slow, requires significant space, and is unsuitable for belt replacement in confined spaces, resulting in high machine wear and tear. Furthermore, both replacing the old belt and winding the new one require foundations and traction power, making it inconvenient to use. Moreover, most new belt replacements do not consider the recycling of the old belt, making old belt recovery particularly troublesome.
[0003] Therefore, there is an urgent need for a belt replacement device for conveyors that is time-saving, labor-saving, low-cost, highly efficient, and suitable for use in confined spaces. Summary of the Invention

[0014] Furthermore, the self-made clamping device described in step S1 includes a rotary bearing, a two-way clamping plate disposed on the rotary bearing, a spring and a triangular tooth disposed on the two-way clamping plate.
[0015] Furthermore, the bidirectional clamping plate includes a first clamping plate and a second clamping plate disposed opposite to each other on both sides of the rotary bearing;
[0016] Both the first clamping plate and the second clamping plate include an upper clamping plate and a lower clamping plate arranged at an angle;
[0017] The upper and lower clamping plates on the first and second clamping plates can rotate around the rotary bearing.
[0018] Furthermore, the triangular teeth are evenly spaced at multiple intervals on the upper and lower clamping plates at the ends away from their intersection.
[0019] Furthermore, the spring is located at the angle between the upper and lower clamping plates, and its two free ends are engaged with the inner surface of the triangular teeth.
[0020] Furthermore, the self-made guide roller in step S2 includes a support roller and a clamping assembly disposed on the support roller;

[0029] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:
[0030] (1) The present invention provides a method for quick belt replacement of a belt conveyor. By designing a self-made belt clamping device and a belt collection guide roller, the old belt is disconnected during operation. One end is connected to the new belt through a self-made clamping device, and the other end is connected and fixed to the belt collection guide roller. A drive device is connected to the self-made belt collection guide roller, and the drive drives the guide roller to rotate, thereby continuously recovering the old belt connected to the self-made guide roller and gradually replacing the old belt with the new belt, thus realizing the quick replacement of the new belt and the collection of the old belt of the belt conveyor. The belt replacement method of the present invention is time-saving, labor-saving, low-cost, and highly efficient. It is also applicable to belt replacement in narrow spaces. It can solve the problems of existing belt replacement methods that use cranes, winches and other mechanical equipment to pull out the old belt and pull up the new belt, which wastes manpower, has high costs, slow construction speed, and requires a large space. It is not suitable for belt replacement in narrow spaces, and the recovery of the old belt is troublesome.
[0031] (2) The present invention provides a method for quick belt replacement of a belt conveyor, which utilizes the existing belt conveyor's tripod to provide support for the self-made guide roller and the existing drive device to provide power for the self-made guide roller, making belt replacement more convenient and effectively reducing the work of wiring for construction and the wear and tear of machinery.
[0032] (3) The belt quick replacement method of the belt conveyor of the present invention uses a self-made belt clamping device consisting of two spring clamps with triangular teeth at both ends. The spring clamps can rotate around the intermediate bearing, and the connection is stable and stable. When the clamping device passes the end side roller, the clamp angle can be adjusted by itself, which effectively avoids the belt from falling off and breaking at the head and tail pulleys due to the instability of the clamp.
[0033] (4) The present invention provides a method for quick belt replacement of a belt conveyor. The self-made guide roller is equipped with an arc-shaped clamp. The arc-shaped clamp has the same curvature as the outer surface of the idler roller on the self-made guide roller. After the arc-shaped clamp clamps the belt, the guide roller is driven to rotate by the drive device, so that the old belt is collected at the same time as the new belt is replaced, which effectively reduces the cleaning work of the old belt.
[0034] (5) The belt replacement method of the belt conveyor of the present invention uses a self-made belt clamping device and a self-made guide roller that can be reused, which can greatly save construction costs while improving belt replacement efficiency. Attached Figure Description

[0045] Existing belt conveyor belt replacement technology utilizes cranes, winches, and other mechanical equipment to pull out the old belt and install the new one. This method is labor-intensive, costly, slow, and requires a large space, making it unsuitable for belt replacement in confined spaces. Furthermore, it presents the problem of cumbersome old belt retrieval. Based on these reasons, if... Figure 1 As shown, the present invention provides a method for quick belt replacement of a belt conveyor, which is used to replace the old belt of the belt conveyor, including steps S1 to S5.
[0046] Furthermore, such as Figure 2 This is a schematic diagram of a belt conveyor for quick belt replacement.

Located at the angle between the upper and lower clamping plates, its two free ends are locked inside the triangular teeth 44. Under normal conditions, both the first clamping plate 421 and the second clamping plate 422 are closed. The upper and lower clamping plates on the first clamping plate 421 and the second clamping plate 422 can rotate around the rotating bearing 41. When in use, the triangular teeth 44 at the outer ends of the first clamping plate 421 and the second clamping plate 422 open the upper and lower clamping plates, insert the belt between the upper and lower clamping plates, and press the upper and lower triangular teeth into the belt for fixation, thereby realizing the meshing connection between the new and old belts.
[0049] Step S2: Remove the third guide roller from the third tripod of the belt conveyor, install the self-made guide roller, and connect the drive device to the self-made guide roller; specifically, remove the third guide roller from the third tripod 3 of the belt conveyor, and at the same time, install the self-made guide roller 6 on the third tripod 3, and connect the drive device 7 to the self-made guide roller 6; the self-made guide roller 6 is fixed by the third tripod on the belt conveyor.
[0050] Furthermore, such as Figure 4 This is a schematic diagram of the structure of a self-made guide roller; for example... Figure 5 This is a schematic diagram of the planar structure of the arc-shaped clamping piece on the self-made guide roller; for example... Figure 6 This is a side view of the self-made guide roller 6; the self-made guide roller 6 includes a support roller 61 and a clamping assembly 62 disposed on the support roller 61; the number of clamping assemblies 62 is determined according to actual needs; when there are two or more clamping assemblies 62, they are respectively disposed on the outer surface of the support roller 61 along its central axis; during operation, the support roller 61 is disposed on the third tripod 3.
[0051] Furthermore, such as Figure 5 and Figure 6As shown, the clamping assembly 62 includes a rotating shaft 621, a latch 622, and an arc-shaped clamping piece 623 on the rotating shaft 621; the surface of the roller 61 is provided with a groove to accommodate the rotating shaft 621; the rotating shaft 621 is arranged along its central axis on the outer surface of the roller 61; the arc of the arc-shaped clamping piece 623 is consistent with the arc of the surface of the roller 61; the arc-shaped clamping piece 623 is provided with a latching hole 624 that matches the latch 622; the position of the latch 622 on the surface of the roller 61 corresponds to the position of the latching hole 624; When the arc-shaped clamp 623 is engaged, the locking hole 624 engages precisely with the locking buckle 622; the locking buckle 622 is a triangular plate-shaped structure with its tip pointing upwards; the locking buckle 622 is provided with a pin hole 625; the number and position of the locking holes 624 on the arc-shaped clamp 623 correspond to the number and position of the locking buckles 622 on the idler roller 61; there are at least two locking holes 624 and at least two locking buckles 622; after the belt is placed between the inner surface of the arc-shaped clamp 623 and the outer surface of the idler roller 61, the belt is passed through the locking buckle 622, a pin is installed on the locking buckle 622, and the belt is then locked onto the idler roller 61.
[0052] Step S3: Fix the end of the old belt away from the self-made clamping device to the self-made guide roller; specifically, connect the other end of the old belt 5 to the self-made guide roller 6 through the buckle 622 and the arc-shaped clamp 623 on the self-made guide roller 6.
[0053] Step S4: Start the drive device to drive the self-made guide roller to rotate, which in turn drives the old belt to rotate and gradually wind around the self-made guide roller. At the same time, the new belt is replaced by the rotation of the old belt. Specifically, start the drive device 7 to drive the self-made guide roller 6 to rotate, which in turn drives the old belt 5 to rotate and gradually wind around the self-made guide roller 6. At the same time, the new belt is slowly replaced by the rotation of the old belt.
[0054] S5: After the end of the old belt held by the belt clamping device reaches the position of the self-made guide roller, turn off the drive device, remove the belt clamping device and the self-made guide roller, reinstall the third guide roller on the third tripod, and glue the end of the new belt to achieve the replacement of the new belt and the recycling of the old belt; specifically, as the drive device 7 is driven, the belt rotates, and after the end of the old belt held by the belt clamping device 4 reaches the position of the self-made guide roller 6, turn off the drive device 7, remove the belt clamping device 4 and the self-made guide roller 6, install the original guide roller on the third tripod 3, and glue the new belt; in this way, the replacement of the new belt and the recycling of the old belt are completed.
[0055] This invention provides a method for rapid belt replacement in belt conveyors. By designing a self-made belt clamping device and a belt collection guide roller, the old belt is disconnected during operation. One end is connected to the new belt via the self-made clamping device, and the other end is connected and fixed to the belt collection guide roller.
