Description

Technical Field

[0001] This utility model relates to the field of conveyor belt spreading technology, and in particular to a conveyor belt rapid spreading device. Background Technology

[0002] Conveyor belts, also known as transport belts, are used in belt conveyors to carry and transport materials. They are composite products of rubber and fiber metal, or composite products of plastic and fabric. In logistics distribution centers, warehouses and other places, conveyor belts are used for sorting, handling and transferring goods, improving production efficiency and reducing manual handling costs.

[0003] The installation of new belts is a crucial step in belt conveyor replacement and maintenance. Due to the weight and length of the new belts, a truck crane and loader are required for assistance. Personnel intervention is also needed to apply traction and slowly unwind the belts, posing significant safety risks. To facilitate loading and transport and prevent vehicles from exceeding height limits, existing belt manufacturers often roll excessively long belts into "eyeglass rolls" from both ends towards the middle. In this type of roll, the two ends are wound into two separate core cylinders. Therefore, during the installation process, one roll must be fully unwound before the next adjacent roll can be unwound. In limited maintenance work areas, using a loader to drag the belt installation is extremely difficult. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a conveyor belt rapid unwinding device, which aims to improve the problem that the limited space in the prior art makes it inconvenient to unwind excessively long belts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a conveyor belt rapid unwinding device, comprising a rotating shaft, a belt roll fixedly connected to the outer wall of the rotating shaft, rollers fixedly connected to both ends of the outer wall of the rotating shaft, V-shaped grooves formed on the outer walls of the rollers, slidably connected to the outer walls of the V-shaped grooves, rings fixedly connected to both ends of the front side of the rotating shaft, a common pull rope fixedly connected to the front side of the two rings, a pull ring slidably connected to the outer wall of the pull rope, and a limiting mechanism provided on the outer wall of the rotating shaft, the limiting mechanism being used to limit the belt roll to prevent it from moving left or right.

[0006] As a further description of the above technical solution:

[0007] The limiting mechanism includes two limiting discs, the interiors of which are respectively located on the left and right sides of the outer wall of the rotating shaft. Each limiting disc has a groove on its top and sliding grooves on its front and rear sides. Sliding blocks are slidably connected to the interiors of multiple sliding grooves. A corresponding connecting plate is fixedly connected to one side of each sliding block. A fixing bolt is rotatably connected to the top of each connecting plate. L-shaped plates are fixedly connected to both ends of the opposite sides of the two connecting plates. Limiting bolts are rotatably connected to one side of each L-shaped plate.

[0008] As a further description of the above technical solution:

[0009] One end of each of the two slings is fixedly connected to a knotter, and the other end of each of the two slings passes through the knotter.

[0010] As a further description of the above technical solution:

[0011] The two limiting discs are provided with sliding grooves on their left and right sides, and the sliding blocks are fixedly connected to sliders on their left and right sides, with the sliders slidingly connected to the interior of the corresponding sliding grooves.

[0012] As a further description of the above technical solution:

[0013] Each of the limiting bolts has a washer slidably connected to its outer wall, and one side of each washer is respectively attached to one side of the corresponding L-shaped plate.

[0014] As a further description of the above technical solution:

[0015] Both ends of the two limiting discs on opposite sides are provided with reserved holes, and multiple limiting bolts pass through the L-shaped plate and are threaded into the corresponding reserved holes.

[0016] As a further description of the above technical solution:

[0019] The inner sides of both grooves are slidably connected to the outer wall of the shaft, and the grooves are matched to the size of the shaft.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by winding the belt onto a rotating shaft, and connecting the crane using a sling and roller V-groove, pulling the pull ring applies force to the rotating shaft via a pull rope. During lifting, the roller rotates and continues to rotate under the weight of the belt below, achieving automatic belt unfolding. Furthermore, the unfolded belt stack occupies little space, reducing the area required for belt replacement.

[0022] 2. In this utility model, by placing the limiting disc through the groove on both sides of the outer wall of the rotating shaft close to the belt roll, moving the connecting plate down to fit the top of the rotating shaft, rotating the limiting bolt to fix the connecting plate, and rotating the fixing bolt to limit the position of the limiting disc, the stable positioning of the belt roll during the belt unwinding process is achieved, ensuring that the conveyor belt can be smoothly unwinded along the predetermined path and avoiding belt unwinding problems caused by deviation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a conveyor belt rapid unfolding device, comprising a rotating shaft 1, a belt roll 3 fixedly connected to the outer wall of the rotating shaft 1, the belt roll 3 being the conveyor belt to be unfolded, rollers 4 fixedly connected to both ends of the outer wall of the rotating shaft 1, the rollers 4 being able to roll on a suspension cable 6 for easy movement of the device, V-shaped grooves 5 being formed on the outer walls of both rollers 4, the V-shaped grooves 5 being able to tightly engage with the suspension cable 6 to prevent the rollers 4 from falling off the suspension cable 6, the suspension cable 6 being slidably connected to the outer wall of the V-shaped grooves 5, the suspension cable 6 being used to suspend and support the entire device, enabling it to move within a certain space. The rotating shaft 1 has two fixed rings 7 at its front ends, which provide connection points for the pull rope 8. The same pull rope 8 is fixedly connected to the front of both rings 7. The pull rope 8 is used to control the direction of movement of the device. Pull rings 10 are slidably connected to the outer wall of the pull rope 8. Pull rings 10 are easy for operators to hold and pull the pull rope 8. The outer wall of the rotating shaft 1 is provided with a limit mechanism 2, which is used to limit the belt roll 3 to prevent it from moving left and right. One end of the two slings 6 is fixedly connected to a rope knotter 9. The rope knotter 9 can adjust the length of the slings 6 to adapt to different usage scenarios.

[0032] Specifically, first, the belt roll 3 is placed on the outer wall of the rotating shaft 1, and at the same time, the sling 6 is placed in the V-groove 5 on the outer wall of the roller 4. The top of the sling 6 is connected to the crane. At this time, the pull ring 10 is pulled, and the horizontal tension is applied to the rotating shaft 1 through the pull rope 8 to prevent the belt roll 3 from swinging too much during the lifting process. At this time, the height of the belt roll 3 is slowly raised, and the roller 4 rotates. Under the action of the weight of the belt below, the roller 4 always keeps rotating and finally completes the automatic unfolding of the belt. The unfolded belt is stacked on the ground, occupying only a small space, which greatly reduces the area occupied by the belt replacement site. The rope knotter 9 can adjust the spacing and tension between the two slings 6. When it is necessary to adjust the position of the device according to the on-site installation environment or the size of the belt roll 3, the sling 6 can be adjusted through the rope knotter 9.

[0033] Reference Figure 3 , Figure 4 and Figure 5The limiting mechanism 2 includes two limiting discs 201, which are used to limit the belt roll 3 from the left and right sides. The interiors of the two limiting discs 201 are respectively set on the left and right sides of the outer wall of the rotating shaft 1 to fix the position of the limiting discs 201 on the rotating shaft 1. The top of each limiting disc 201 is provided with a groove 202, which can be used to place some auxiliary tools or parts for easy operation. The front and rear sides of the interior of each limiting disc 201 are provided with sliding grooves 203, which provide sliding tracks for sliding blocks 204. Sliding blocks 204 are slidably connected inside the sliding grooves 203. The sliding blocks 204 can move within the sliding grooves 203 to adjust the position of the connecting plate 205. Each side of the sliding blocks 204 is fixedly connected to a corresponding connecting plate 205, which is used to connect the sliding blocks 204 and other components. The top of each of the two connecting plates 205 is rotatably connected with a fixing bolt 206. The fixing bolt 206 can be tightened to fix the position of the connecting plate 205 on the limiting disc 201. L-shaped plates 207 are fixedly connected to both ends of the opposite side of the two connecting plates 205. The L-shaped plates 207 can increase the strength and stability of the limiting structure. Limiting bolts 208 are rotatably connected to one side of each of the multiple L-shaped plates 207. The limiting bolts 208 can be rotated to adjust the degree of limiting of the belt roll 3. Slide grooves 11 are opened on the left and right sides of the interior of the two limiting discs 201. The slide grooves 11 cooperate with the sliders 12 to further limit the movement direction of the sliding block 204. Sliders 12 are fixedly connected to the left and right sides of the multiple sliding blocks 204. The sliders 12 slide in the slide grooves 11 to ensure the smooth movement of the sliding block 204. The multiple sliders 12 are respectively slidably connected to the interior of the corresponding slide grooves 11.

[0034] Specifically, after the belt roll 3 is fitted onto the outer wall of the rotating shaft 1, two limiting discs 201 are inserted into the outer walls of the rotating shaft 1 through the grooves 202 and close to the sides of the belt roll 3. At this time, the connecting plate 205 is moved downward to fit against the top of the rotating shaft 1. Then, multiple limiting bolts 208 are rotated to fix the connecting plate 205, and the fixing bolts 206 are rotated to fix and limit the position of the limiting discs 201. This ensures that the belt roll 3 remains stable during the belt unfolding process, ensuring that the conveyor belt can unfold smoothly according to the predetermined path and avoiding problems caused by the belt roll 3's deviation. It also provides dual guidance for the movement of the sliding block 204 within the limiting discs 201. In addition to the guidance of the sliding groove 203 in the front and rear directions, the sliding of the slider 12 in the sliding groove 11 in the left and right directions further ensures the stability of the movement of the sliding block 204, thereby making the position adjustment of the connected plate 205 and subsequent components more precise.

[0035] Reference Figure 3 , Figure 4 and Figure 5Each of the multiple limiting bolts 208 has a slidably connected washer 13 on its outer wall. The washer 13 increases the contact area between the limiting bolt 208 and the L-shaped plate 207, dispersing pressure. One side of each washer 13 is in contact with one side of the corresponding L-shaped plate 207, ensuring that the washer 13 can function effectively. Each of the two limiting discs 201 has a reserved hole 14 at both ends of its opposite side. The reserved hole 14 provides an installation position for the limiting bolts 208. All the limiting bolts 208 penetrate the L-shaped plate 207 and are threaded into the corresponding reserved hole 14. The threaded connection achieves a fixed connection between the limiting bolts 208 and the limiting discs 201. The limit on the belt roll 3 is then adjusted. Triangular fixing blocks 15 are fixedly connected to one side of multiple L-shaped plates 207. The triangular fixing blocks 15 can enhance the stability of the connection between the L-shaped plates 207 and the connecting plate 205. The other side of multiple triangular fixing blocks 15 is fixedly connected to one side of the corresponding connecting plate 205, further reinforcing the connection between the L-shaped plates 207 and the connecting plate 205. The inner sides of the two grooves 202 are slidably connected to the outer wall of the rotating shaft 1. The cooperation between the grooves 202 and the rotating shaft 1 allows the limiting disc 201 to be stably installed on the rotating shaft 1. The size of the grooves 202 and the rotating shaft 1 are matched to ensure that the connection between the two is tight and stable.

[0036] Specifically, when the rotating limit bolt 208 abuts against the side of the belt roll 3, the washer 13 can prevent the limit bolt 208 from causing excessive local pressure on the L-shaped plate 207 and damaging it. The reserved hole 14 provides an installation position for the limit bolt 208, and the threaded connection makes the limit bolt 208 more stable. The triangular fixing block 15 enhances the stability of the connection between the L-shaped plate 207 and the connecting plate 205, so that the limit disc 201 can be tightly and stably fitted on the rotating shaft 1. During the operation of the device, it ensures that the limit disc 201 rotates or moves synchronously with the rotating shaft 1, and ensures that the limit mechanism 2 can perform its limit function on the belt roll 3 normally.

[0037] Working principle: When using this conveyor belt quick unfolding device, first, the belt roll 3 is placed on the outer wall of the rotating shaft 1, and at the same time, the sling 6 is placed in the V-groove 5 on the outer wall of the roller 4. The top of the sling 6 is connected to the crane. At this time, the pull ring 10 is pulled, and the horizontal tension is applied to the rotating shaft 1 through the pull rope 8 to prevent the belt roll 3 from swinging too much during the lifting process. At this time, the height of the belt roll 3 is slowly raised, and the roller 4 rotates. Under the action of the weight of the belt below, the roller 4 always keeps rotating and finally completes the automatic unfolding of the belt. The unfolded belt is stacked on the ground, occupying only a small space and greatly reducing the area occupied by the belt replacement site.

[0038] After the belt roll 3 is fitted onto the outer wall of the rotating shaft 1, the two limiting discs 201 are inserted into the outer walls of the rotating shaft 1 through the grooves 202 and close to the sides of the belt roll 3. At this time, the connecting plate 205 is moved downward to fit against the top of the rotating shaft 1. Then, multiple limiting bolts 208 are rotated to fix the connecting plate 205, and the fixing bolts 206 are rotated to fix and limit the position of the limiting discs 201. This ensures that the belt roll 3 is always in a stable state during the belt unfolding process, ensuring that the conveyor belt can unfold smoothly according to the predetermined path and avoiding problems caused by the belt roll 3 shifting.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
