Description

Technical Field

[0001] This utility model relates to the field of logistics and warehousing technology, specifically a side guide wheel for a cargo platform. Background Technology

[0002] Aisle stacker cranes are the core handling equipment in automated storage and retrieval systems (AS / RS). They enable precise storage and retrieval of goods through walking, lifting, and forklift mechanisms. Side guide wheels are key components that ensure stable operation along narrow aisles, effectively preventing rack collisions, reducing frictional wear through rolling contact, maintaining vertical stability of the loading platform, improving positioning accuracy, extending equipment lifespan, and ensuring operational safety in high-density storage environments.

[0003] With the increasing automation of warehousing, equipment such as aisle stacker cranes are widely used. As the core transport component of the stacker crane, the loading platform needs to achieve precise storage and retrieval operations in three-dimensional space. The side guide wheels must ensure the smooth lifting and guiding of the loading platform along the column. The matching accuracy between the side guide wheels and the guide rails directly affects the stability of the equipment operation. Due to the large height of the stacker crane columns and the fact that the loading platform is a large welded structure, dimensional tolerance control is difficult. In actual installation, if the gap between the side guide wheels and the guide rails is not properly adjusted, it will cause vibration and deviation during the lifting and lowering of the loading platform, which will reduce the accuracy of operation and pose safety hazards. To address these issues, we provide a loading platform side guide wheel to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a side guide wheel for a cargo platform to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a side guide wheel for a cargo platform, comprising a shaft, an adjustment mechanism provided on the outside of the shaft, the adjustment mechanism comprising an adjustment shaft, a connecting cylinder fixedly connected to the inner wall of the adjustment shaft, a driven adjustment screw threadedly connected to the inner wall of the connecting cylinder, a first bevel gear fixedly connected to one end of the driven adjustment screw, and a second bevel gear meshing with the outer surface of the first bevel gear;

[0006] One end of the shaft is fixedly connected to a limiting disk, the outer surface of the limiting disk is fixedly connected to a second bevel gear, and an elastic retaining ring for the shaft is provided between the adjusting shaft and the shoulder of the limiting disk.

[0007] Preferably, the outer surface of the driven adjusting screw is rotatably connected to a limiting shell, and the outer surface of the limiting shell is rotatably connected to a rotating disk and a limiting disk. By setting the limiting shell, the first bevel gear and the second bevel gear are effectively limited.

[0008] Preferably, a limiting slip ring is rotatably connected to the outer surface of the shaft, and a limiting groove adapted to the limiting slip ring is formed on the outer surface of the adjusting shaft. Through the synergistic effect of the limiting slip ring and the limiting groove, the adjusting shaft is effectively limited.

[0009] Preferably, the inner wall of the adjusting shaft is rotatably connected to a side guide wheel body, and the outer surface of the shaft body is provided with an adjusting operating surface. By setting the adjusting operating surface, it is more convenient for the operator to use external tools to turn the shaft body.

[0010] Preferably, the shaft body is provided with a fixing mechanism on its exterior. The fixing mechanism includes a flange body, the inner wall of the flange body is sleeved with the shaft body, one end of the shaft body is provided with a square fixing block, and the inner wall of the flange body is provided with a square embedding groove that matches the square fixing block.

[0011] Preferably, the outer surface of the flange body is provided with a fixing screw hole, and the inner wall of the fixing screw hole is threaded with a fixing bolt. By tightening the fixing bolt, the flange body can be effectively installed into the loading platform.

[0012] Preferably, a baffle and a shaft elastic washer are fitted onto the outer surface of the shaft body, and a locking bolt is threaded onto the inner wall of the shaft body. By tightening the locking bolt, the shaft elastic washer and the locking bolt can be effectively pre-tightened, so that the two are firmly fixed to the surface of the flange body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The side guide wheel of the loading platform is adjusted by the coordinated arrangement of the components in the adjustment mechanism. By adjusting the position of the adjustment shaft so that it is eccentrically parallel to the shaft body, the distance between the side guide wheel body and the column can be adjusted, ensuring the precise operation of the loading platform. At the same time, it reduces the disassembly and assembly of parts. This optimization significantly improves the working efficiency of the device.

[0015] 2. Through the coordinated arrangement of components in the fixing mechanism, the side guide wheel of the loading platform achieves the synergistic effect of the fixing bolts and the axle elastic washers. This not only securely confines the device between the loading platform and the column, but also allows for quick adjustment of the position of the side guide wheel body by tightening the fixing bolts and the axle elastic washers, further enhancing the flexibility of the device.

Detailed Implementation

[0022] 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.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a technical solution for a side guide wheel of a loading platform, including a shaft 1. An adjustment mechanism 2 is provided on the outside of the shaft 1. The adjustment mechanism 2 includes an adjustment shaft 201. A connecting cylinder 202 is fixedly connected to the inner wall of the adjustment shaft 201. By driving the connecting cylinder 202 to move, the adjustment shaft 201 can be driven to move synchronously, effectively adjusting the eccentric angle of the adjustment shaft 201 relative to the shaft 1.

[0024] The inner wall of the connecting cylinder 202 is threaded with a driven adjusting screw 203. One end of the driven adjusting screw 203 is fixedly connected to a first bevel gear 204. The outer surface of the first bevel gear 204 is meshed with a second bevel gear 205. By driving the first bevel gear 204 to rotate, the driven adjusting screw 203 can be driven to rotate simultaneously.

[0025] One end of the shaft 1 is fixedly connected to a limiting disk 206. The outer surface of the limiting disk 206 is fixedly connected to the second bevel gear 205. An elastic retaining ring 207 is provided between the adjusting shaft 201 and the shoulder of the limiting disk 206. The elastic retaining ring 207 can effectively and precisely limit the adjusting shaft 201 on the shaft 1, effectively preventing its axial movement, making the device more stable during use.

[0026] The outer surface of the limiting disc 206 is provided with a limiting groove that is compatible with the shaft elastic retaining ring 207. By installing the shaft elastic retaining ring 207 into the limiting groove, the adjusting shaft 201 is effectively limited.

[0027] The outer surface of the driven adjusting screw 203 is rotatably connected to the limiting shell 208. The outer surface of the limiting shell 208 is rotatably connected to the rotating disk and the limiting disk 206. By setting the limiting shell 208, the first bevel gear 204 and the second bevel gear 205 are effectively limited, making the first bevel gear 204 and the second bevel gear 205 more stable during the linkage process.

[0028] A limiting slip ring 209 is rotatably connected to the outer surface of the shaft 1. A limiting groove 210 adapted to the limiting slip ring 209 is provided on the outer surface of the adjusting shaft 201. Through the synergistic effect of the limiting slip ring 209 and the limiting groove 210, the adjusting shaft 201 is effectively limited, so that when the adjusting shaft 201 is eccentrically adjusted, it can only move along the length direction of the limiting groove 210.

[0029] The inner wall of the adjusting shaft 201 is rotatably connected to the side guide wheel body 211. The outer surface of the shaft body 1 is provided with an adjustment operation surface 212. By adjusting the setting of the operation surface 212, it is more convenient for the staff to use external tools to turn the shaft body 1. By adjusting the eccentricity of the adjusting shaft 201 relative to the shaft body 1, the side guide wheel body 211 can always be in close contact with the column, ensuring the precise and stable operation of the loading platform. This optimization significantly improves the working efficiency of the device.

[0030] like Figure 1 and Figure 5 As shown, a fixing mechanism 3 is provided on the outside of the shaft 1. The fixing mechanism 3 includes a flange body 301. The inner wall of the flange body 301 is sleeved with the shaft 1. A square fixing block is provided at one end of the shaft 1, and a square embedding groove adapted to the square fixing block is provided on the inner wall of the flange body 301. By setting the flange body 301, the vibration resistance stability of the shaft 1 is effectively improved, and the situation where the shaft 1 rotates unexpectedly due to external force after the eccentric adjustment of the adjusting shaft 201 is avoided.

[0031] The outer surface of the flange body 301 is provided with a fixing screw hole 302, and the inner wall of the fixing screw hole 302 is threaded with a fixing bolt 303. By tightening the fixing bolt 303, the flange body 301 can be effectively installed into the loading platform.

[0032] Multiple fixing screw holes 302 are evenly distributed along the circumference on the surface of the flange body 301. This structural design ensures that after the adjustment shaft 201 completes the eccentric adjustment, the operator can use the fixing bolts 303 to fix the flange body 301 again. This multi-hole layout not only maintains the structural stability of the device, but also provides a convenient fastening solution for subsequent adjustment and maintenance.

[0033] A baffle 304 and a shaft elastic washer 305 are fitted onto the outer surface of the shaft body 1. A locking bolt 306 is threaded onto the inner wall of the shaft body 1. By tightening the locking bolt 306, the shaft elastic washer 305 and the locking bolt 306 can be effectively pre-tightened, so that the two are firmly fixed to the surface of the flange body 301. Through the cooperation of the shaft elastic washer 305 and the locking bolt 306, the installation stability of the flange body 301 is significantly improved.

[0034] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0035] Working Principle: This utility model is mainly used for the loading platform of a stacker crane. The side guide wheel body 211 is installed on both sides of the loading platform. When the loading platform rises and falls along the column, the side guide wheel body 211 is in close contact with the surface of the column. When there is a gap between the side guide wheel body 211 and the surface of the column, the constraint of the shaft 1 is released by loosening the fixing bolt 303 and the locking bolt 306. Then, one hand supports the adjusting shaft 201, and the other hand uses an external tool to turn the shaft 1 through the adjusting operating surface 212. The rotation of the shaft 1 drives the first bevel gear 204 on the surface of the second bevel gear 205 to rotate. The rotation of the first bevel gear 204 drives the connecting cylinder 202 on the surface of the driven adjusting screw 203 to move. During the movement of the connecting cylinder 202, the combined action of the limiting slip ring 209 and the limiting slide groove 210 causes the adjusting shaft 201 to move eccentrically parallel to the shaft body 1. This utilizes the eccentric principle to adjust the distance between the side guide wheel body 211 and the column, ensuring that the side guide wheel body 211 and the column are tightly fitted again. This prevents the loading platform from shaking or shifting during lifting and ensures that it runs precisely along the predetermined vertical track, guaranteeing the accuracy and stability of goods during storage and retrieval.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
