Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, and particularly relates to an anti-derailment idler trolley. Background Technique

[0002] A belt conveyor is a common material conveying device. In the application of the belt conveyor, the idler trolley, as an important component of the belt conveyor, mainly plays the roles of supporting the weight of the conveyor belt and materials, reducing the running resistance, preventing the conveyor belt from deviating, and buffering the impact force of the materials.

[0003] For the traditional idler trolley, the installation position of the idler is mostly in a fixed state, resulting in the problem that the lifting position of the idler is inconvenient to adjust during use, affecting the supporting effect on the conveyor belt. At the same time, during the process of preventing the conveyor belt from deviating, the conveyor belt is prone to shaking. When the shaking amplitude is too large, the conveyor belt is prone to derailment. For this reason, we propose an anti-derailment idler trolley. Summary of the Invention

[0004] The purpose of the utility model is to provide an anti-derailment idler trolley to solve the problems raised in the above background technique.

[0005] The purpose of the utility model can be realized by the following technical solutions: an anti-derailment idler trolley, including two groups of symmetrically arranged lower guide rails. Upper guide rails are placed on the upper surfaces of the two groups of lower guide rails. A limiting groove is jointly opened in the middle of one side of the outer surfaces of the lower guide rail and the upper guide rail. A connection port is jointly opened in the middle of the other side of the outer surfaces of the lower guide rail and the upper guide rail. A first supporting shaft is installed on the closer side between the two groups of lower guide rails. Limiting blocks are arranged at both ends of the first supporting shaft. The limiting blocks are clamped and installed in the limiting groove. Locking screw holes are opened in the middle of the far ends of the limiting blocks away from each other. The locking screw holes are aligned with the connection port. A locking bolt is spirally inserted into the inner surface of the connection port. The output end of the locking bolt is spirally inserted into the locking screw hole;

[0006] Both ends of the outer surface of the first supporting shaft are sleeved and installed with brackets. A second supporting shaft is jointly arranged on the upper part of the closer side between the brackets. A first idler is sleeved and installed in the middle of the outer surface of the second supporting shaft. A first deviation rectifying roller is sleeved and installed at one end of the outer surface of the second supporting shaft. A second deviation rectifying roller is sleeved and installed at the other end of the outer surface of the second supporting shaft. A second idler is sleeved and installed in the middle of the outer surface of the first supporting shaft. Threaded deviation rectifying ridges are arranged at both ends of the middle of the outer surface of the second idler. The thread directions of the two ends of the deviation rectifying ridges are arranged in the opposite direction.

[0007] As a further improvement of the utility model, universal wheels are arranged at both ends of the lower surface of the lower guide rail.

[0008] As a further improvement of the present utility model, first docking pieces are provided on the upper parts of one ends of the lower guide rail and the upper guide rail respectively, and second docking pieces are provided in the middle parts of the other ends of the lower guide rail and the upper guide rail respectively. A plurality of connecting screw holes are formed in the upper surfaces of the first docking piece and the second docking piece, and fixing bolts are installed by spiral insertion on the inner surfaces of the connecting screw holes of the first docking piece.

[0009] As a further improvement of the present utility model, limit discs are sleeved and installed at both ends of the middle part of the outer surface of the first support shaft.

[0010] As a further improvement of the present utility model, a plurality of limit rings are evenly sleeved on the outer surface of the second support shaft, and the limit rings are respectively located at both ends of the first idler roller, the first deviation rectifying roller and the second deviation rectifying roller.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model can facilitate the adjustment of the support position of the idler roller corresponding to the conveyor belt, thereby avoiding the problem that the lifting position is inconvenient to adjust caused by the complex disassembly after the traditional idler roller is fixed, which is beneficial to the corresponding adjustment according to the specific support requirements of the conveyor belt, and further improving the support effect of the idler roller on the conveyor belt;

[0013] When the conveyor belt shakes during the deviation rectification process, the present utility model can provide a corresponding reverse tensile force to offset the shaking amplitude of the conveyor belt, which is beneficial to improving the stability during the operation of the conveyor belt, thereby avoiding the problem of the conveyor belt derailing caused by too large deviation rectification shaking amplitude.

Specific implementation manner

[0020] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 As shown, a non-derailing supporting roller trolley includes two groups of symmetrically arranged lower guide rails 1. Universal wheels 3 are provided at both ends of the lower surface of the lower guide rail 1. Upper guide rails 2 are placed on the upper surfaces of the two groups of lower guide rails 1. First docking pieces 6 are provided at the upper parts of one ends of the lower guide rail 1 and the upper guide rail 2, and second docking pieces 7 are provided in the middle of the other ends of the lower guide rail 1 and the upper guide rail 2. A plurality of connection screw holes 8 are opened on the upper surfaces of the first docking piece 6 and the second docking piece 7, and a fixing bolt 9 is installed by spiral insertion on the inner surface of the connection screw hole 8 of the first docking piece 6;

[0022] A limit groove 4 is jointly opened in the middle of one side of the outer surfaces of the lower guide rail 1 and the upper guide rail 2, and a connection port 5 is jointly opened in the middle of the other side of the outer surfaces of the lower guide rail 1 and the upper guide rail 2. A first supporting shaft 10 is installed on the closer side between the two groups of lower guide rails 1. Limit blocks 11 are provided at both ends of the first supporting shaft 10. The limit blocks 11 are installed by being snapped into the limit groove 4. Locking screw holes 12 are opened in the middle of the ends of the limit blocks 11 away from each other, and the locking screw holes 12 are aligned with the connection port 5. A locking bolt 13 is installed by spiral insertion on the inner surface of the connection port 5, and the output end of the locking bolt 13 is spirally inserted into the locking screw hole 12;

[0023] Limit discs 14 are sleeved and installed at both ends of the middle part of the outer surface of the first supporting shaft 10. Brackets 15 are sleeved and installed at both ends of the outer surface of the first supporting shaft 10. A second supporting shaft 16 is jointly provided at the upper part of the closer side between the brackets 15. A first supporting roller 18 is sleeved and installed in the middle of the outer surface of the second supporting shaft 16. A first deviation rectifying roller 19 is sleeved and installed at one end of the outer surface of the second supporting shaft 16, and a second deviation rectifying roller 20 is sleeved and installed at the other end of the outer surface of the second supporting shaft 16;

[0024] A number of limiting rings 17 are evenly sleeved on the outer surface of the second supporting shaft 16. The limiting rings 17 are respectively located at both ends of the first supporting roller 18, the first deviation rectifying roller 19 and the second deviation rectifying roller 20. A second supporting roller 21 is sleeved and installed in the middle of the outer surface of the first supporting shaft 10. Deviation rectifying convex stripes 22 in a threaded shape are provided at both ends in the middle of the outer surface of the second supporting roller 21. The thread directions of the deviation rectifying convex stripes 22 at both ends are arranged in the opposite direction.

[0025] When the utility model is in use, first, by placing the limiting blocks 11 arranged at both ends of the first supporting shaft 10 into the limiting grooves 4 opened on the upper surface of the lower guide rail 1, the connection between the first supporting shaft 10 and the two groups of symmetrically arranged lower guide rails 1 is completed. At this time, the upper guide rail 2 can be covered on the upper surface of the lower guide rail 1, and the limiting grooves 4 opened on the lower surface of the upper guide rail 2 are used to cooperate with the limiting grooves 4 opened on the upper surface of the lower guide rail 1 to fit with the limiting blocks 11, and jointly complete the limiting and fixing of the first supporting shaft 10. If the lower guide rail 1 and the upper guide rail 2 need to be extended, the combination of the lower guide rail 1 and the upper guide rail 2 can be butt-jointed through the first butt-joint piece 6 and the second butt-joint piece 7 respectively arranged at both ends, and the extension connection of the combination of the lower guide rail 1 and the upper guide rail 2 is completed by inserting the fixing bolt 9 into the connecting screw hole 8. If extension is not required, the fixing bolts 9 can be respectively inserted into the connecting screw holes 8 opened on the first butt-joint piece 6 and the second butt-joint piece 7, and then the fixed connection installation of the lower guide rail 1 and the upper guide rail 2 is completed;

[0026] Secondly, after the combination of the lower guide rail 1 and the upper guide rail 2 is fixedly connected and installed, the first supporting shaft 10 can be pushed to move horizontally along the limiting groove 4 to complete the adjustment of its lifting and supporting position. When the first supporting shaft 10 moves to a suitable supporting position, the locking bolt 13 can be inserted into the locking screw holes 12 opened on the limiting blocks 11 arranged at both ends of the first supporting shaft 10 through the connection port 5, and continuously tightened until the first supporting shaft 10 presents a fixed state. When the supporting position needs to be adjusted again, only the locking bolt 13 needs to be loosened, and the first supporting shaft 10 is pushed to adjust the position and then tightened again to complete the adjustment of the supporting position, avoiding the problem that the supporting position is difficult to adjust when the supporting shaft is fixedly installed, which affects the supporting effect on the conveyor belt;

[0027] Finally, when the first supporting shaft 10 moves to a suitable supporting position, the conveyor belt can be sleeved on the outer surfaces of the first supporting rollers 18 and the second supporting rollers 21 provided on the first supporting shaft 10 and the second supporting shaft 16. After the sleeving and adjustment of the conveyor belt are completed, it can be started for operation. During the operation of the conveyor belt, the first deviation rectifying rollers 19 and the second deviation rectifying rollers 20 located at both ends of the first supporting roller 18 can be used to perform deviation rectifying operations on the conveyor belt. Since the outer surfaces of the first deviation rectifying roller 19 and the second deviation rectifying roller 20 are provided with deviation rectifying threads in opposite states, during the rotation of the first deviation rectifying roller 19 and the second deviation rectifying roller 20, the deviation rectifying threads can be synchronously driven to rotate. In the case where the deviation rectifying threads are in opposite states, the conveyor belt can be reversely stretched in both directions, and the reverse stretching is used to offset the shaking phenomenon that easily occurs during the deviation rectifying process of the conveyor belt, thereby improving the stability during the operation of the conveyor belt. At the same time, during the conveying and callback process of the conveyor belt, by using the deviation rectifying convex stripes 22 reversely arranged on the second supporting roller 21, a reverse stretching effect in both directions can be generated on the conveyor belt during rotation, further reducing the shaking amplitude of the conveyor belt caused by deviation rectification, thereby avoiding the problem of the conveyor belt derailing due to excessive shaking amplitude.
