Description

Technical Field

[0001] This utility model relates to the field of idler roller trolley technology, and in particular to an anti-tipping and anti-deviation idler roller trolley for long distances. Background Technology

[0002] The idler roller trolley is a specialized auxiliary device adapted for long-distance trolley tensioning scenarios of belt conveyors. Its core purpose is to solve the problems of conveyor belt deviation and sagging caused by excessive tensioning stroke. This device has the advantages of simple and compact structure, can achieve precise anti-tipping and efficient anti-deviation, effectively avoids tearing and wear of the conveyor belt during operation, and thus significantly extends the service life of the conveyor belt, ensuring the stability and continuity of long-distance conveying operations of belt conveyors.

[0003] Existing idler trolleys have two major problems in actual use. On the one hand, if the tension of the belt conveyor is too high during operation, the idler trolley is prone to tipping over due to force imbalance, affecting the continuity and safety of the conveying operation. On the other hand, traditional idler trolleys usually only provide vertical support and limit for the conveyor belt, lacking effective constraints in the lateral direction. When the belt conveyor speed is too fast or the conveyor belt is under uneven force, it is very easy for the conveyor belt to run off to the left or right, which in turn causes the conveyor belt edge to tear and wear excessively, greatly shortening its service life. Utility Model Content

[0004] This utility model relates to a long-distance anti-tipping and anti-deviation idler trolley. The anti-tipping rollers are engaged inside the guide rails, and the anti-tipping rollers, in conjunction with the moving wheels, stably confine the idler trolley to the guide rails, preventing it from deviating or detaching. This fundamentally avoids tipping and effectively ensures the continuity and safety of the idler trolley's operation. The anti-deviation rollers further restrain the conveyor belt structure from both sides, preventing lateral deviation due to excessive transport speed. This effectively prevents edge tearing and excessive wear that significantly shortens the conveyor belt's lifespan. Multiple components of the idler trolley are bolted together, minimizing deformation during transport and facilitating on-site installation and debugging.

[0005] In a first aspect, this utility model provides a long-distance anti-tipping and anti-deviation idler trolley, specifically comprising: an idler frame structure, a guide rail and a conveyor belt structure; anti-tipping seats are bolted to the front and rear ends of the inner side of the idler frame structure; anti-tipping rollers are rotatably mounted on the outer side of the anti-tipping seats; anti-deviation seats are bolted to the upper and lower sides of the idler frame structure; anti-deviation rollers are rotatably mounted on the outer side of the anti-deviation seats; wheel seats are bolted to the front and rear sides of the bottom of the idler frame structure; moving guide wheels are rotatably mounted on the bottom of the wheel seats; an idler seat A is bolted to the center of the top of the idler frame structure; an upper support idler is rotatably mounted on the idler seat A; an idler seat B is bolted to the center of the bottom of the idler frame structure; a lower support idler is rotatably mounted on the idler seat B.

[0006] Furthermore, the outer wall of the anti-deviation roller makes rolling contact with the side of the conveyor belt structure.

[0007] Furthermore, the anti-tipping roller and the moving track wheel are rolled together and clamped on the guide rail.

[0008] Furthermore, the moving track wheel is rolled on the guide rail.

[0009] Furthermore, the anti-tipping roller is tumblingly connected to the guide rail.

[0010] Furthermore, the outer wall of the upper support roller makes rolling contact with the inner top of the conveyor belt structure.

[0011] Furthermore, the outer wall of the lower support roller makes rolling contact with the bottom of the conveyor belt structure.

[0012] This utility model provides a long-distance anti-tipping and anti-deviation idler roller trolley, which has the following beneficial effects: (i) The anti-tipping roller is installed inside the guide rail. Through the cooperation of the moving rail wheel, the roller trolley is stably limited on the guide rail, effectively limiting the risk of the trolley's deviation and separation, avoiding the occurrence of tipping accidents from the root, and ensuring the continuity and safety of the roller trolley operation.

[0013] (ii) By setting anti-deviation rollers, this idler trolley can flexibly resist and precisely limit the conveyor belt structure from both sides. Even if the belt conveyor is traveling at a high speed, it can effectively prevent the conveyor belt structure from deviating to the left or right, thereby preventing the conveyor belt edge from tearing and excessive wear, and avoiding a significant reduction in its service life.

[0014] (III) The multiple components of this idler roller trolley are designed to be detachably connected by bolts. They can be disassembled and stored during transportation, and are not easily deformed due to collisions. The on-site installation process is simple, requiring no complicated tools, and is easy to assemble and debug quickly, thus improving construction efficiency. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please refer to Figures 1 to 5 Example 1: This utility model proposes a long-distance anti-tipping and anti-deviation idler trolley, comprising: an idler frame structure 1, a guide rail 12, and a conveyor belt structure 13. Anti-tipping seats 2 are bolted to the front and rear ends of the inner side of the idler frame structure 1; anti-tipping rollers 3 are rotatably mounted on the outer side of the anti-tipping seats 2; anti-deviation seats 4 are bolted to the upper and lower sides of the idler frame structure 1; anti-deviation rollers 5 are rotatably mounted on the outer side of the anti-deviation seats 4; and anti-deviation rollers 5 are bolted to the front and rear sides of the bottom of the idler frame structure 1. The trolley has a wheel carrier 6; a moving track wheel 7 is rotatably mounted on the bottom of the wheel carrier 6; a roller seat A8 is fixedly mounted on the top center of the roller frame structure 1 by bolts; an upper support roller 9 is rotatably mounted on the roller seat A8; a roller seat B10 is fixedly mounted on the bottom center of the roller frame structure 1 by bolts; a lower support roller 11 is rotatably mounted on the roller seat B10; multiple components in this roller trolley are connected by bolts, which makes it less prone to deformation during transportation, and is also convenient for on-site installation and debugging.

[0020] In Example 2, based on Example 1, the outer wall of the anti-deviation roller 5 rolls in contact with the side of the conveyor belt structure 13; the anti-tipping roller 3 and the moving track wheel 7 are rolled and clamped together on the guide rail 12; the moving track wheel 7 is rolled and installed on the guide rail 12; the idler trolley is engaged inside the guide rail 12 by the anti-tipping roller 3, so that the anti-tipping roller 3 and the moving track wheel 7 cooperate to stably limit the idler trolley on the guide rail 12, preventing the idler trolley from deviating or detaching from the guide rail 12, thus preventing tipping at the source. This effectively ensures the continuity and safety of the idler trolley's operation. The idler trolley is slidably mounted on the guide rail 12 via the moving rail wheel 7. After installation, the anti-tipping seat 2 is fixed to the idler frame structure 1 with bolts. Then, the anti-tipping roller 3 is inserted into the inner side of the guide rail 12, so that the anti-tipping roller 3 and the moving rail wheel 7 cooperate to stably mount the idler frame structure 1 on the guide rail 12. This prevents the idler trolley from detaching or deviating from the guide rail 12 due to the restriction of the anti-tipping roller 3, thus avoiding the idler trolley from tipping over.

[0021] In Example 3, based on Example 2, the anti-tipping roller 3 is rolledly connected to the guide rail 12; the outer wall of the upper support roller 9 rolls in contact with the top inner side of the conveyor belt structure 13; the outer wall of the lower support roller 11 rolls in contact with the bottom of the conveyor belt structure 13; this roller trolley, by setting anti-deviation rollers 5, restricts and supports the conveyor belt structure 13 from both sides, preventing the conveyor belt structure 13 from deviating to the left or right due to excessive transport speed, effectively preventing tearing of the conveyor belt edges and excessive wear that significantly shortens its service life; through the upper support roller... The outer wall of the upper support roller 9 rolls into contact with the top inner side of the conveyor belt structure 13, and the outer wall of the lower support roller 11 rolls into contact with the bottom of the conveyor belt structure 13. The upper support roller 9 and the lower support roller 11 work together to support and lift the conveyor belt structure 13. At the same time, the outer wall of the anti-deviation roller 5 rolls into contact with the side of the conveyor belt structure 13, which limits the left and right direction of the conveyor belt structure 13 and prevents the conveyor belt structure 13 from deviating to the left or right. In this way, the anti-deviation roller 5 works with the upper support roller 9 and the lower support roller 11 to improve the stability of the conveyor belt structure 13.

[0022] Working principle: In use, the idler trolley is first slidably mounted onto the guide rail 12 via the moving track wheel 7. After assembly, the anti-tipping seat 2 is fixedly installed on the idler frame structure 1 with bolts. Then, the anti-tipping roller 3 is inserted into the inside of the guide rail 12. Through the coordinated action of the anti-tipping roller 3 and the moving track wheel 7, the idler frame structure 1 is stably limited on the guide rail 12, preventing the idler trolley from detaching from the guide rail 12 or deviating due to the constraint of the anti-tipping roller 3. This fundamentally prevents the idler trolley from tilting during operation. To mitigate the risk of slippage, the outer wall of the upper support roller 9 rolls against the top inner side of the conveyor belt structure 13, while the outer wall of the lower support roller 11 rolls against the bottom of the conveyor belt structure 13. Through the cooperation of the upper and lower support rollers 9 and 11, a stable support is provided for the conveyor belt structure 13, ensuring balanced force during transport. Simultaneously, the outer wall of the anti-deviation roller 5 rolls against the side of the conveyor belt structure 13, effectively limiting its lateral displacement and preventing deviation during operation. Through the synergistic effect of the anti-deviation roller 5, the upper support roller 9, and the lower support roller 11, the operational stability of the conveyor belt structure 13 is significantly improved, wear is reduced, and service life is extended.
