Description

Technical Field

[0001] The utility model belongs to the field of material equipment, and particularly relates to a sliding guiding structure for a multi-layer shuttle car. Background Technique

[0002] The multi-layer shuttle car is a device commonly used in the warehousing automation system, which can shuttle and transport goods between different floors to ensure the smooth operation of the shuttle car on the track. The sliding guiding structure of the multi-layer shuttle car mainly includes rollers or sliders, and the shuttle car moves on the guide rail through these components. The rollers can reduce friction and ensure the smooth and efficient operation of the shuttle car. When the shuttle car starts, stops or changes direction, a large impact force will be generated. Due to the lack of an elastic support structure in the sliding guiding structure in the related art, the rollers or sliders may be damaged due to excessive load or material fatigue, affecting the normal sliding of the shuttle car. Since the track widths of different warehousing systems may vary slightly, the guiding roller positions of the sliding guiding structure cannot adapt to different track sizes, resulting in problems such as jamming or poor operation due to inconsistent tracks. Summary of the Invention

[0003] In view of this, the utility model aims to solve at least one of the related technical problems to a certain extent.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0006] The two guiding roller structures are symmetrically arranged on the left and right sides of the sliding frame, the guiding roller structures can be slidably matched with the slide rail, the guiding roller structures are connected to the sliding frame through a plurality of adjusting mechanisms, and the adjusting mechanisms are used to adjust the distance between the guiding roller structures and the sliding frame;

[0007] The two mounting structures are symmetrically arranged above the sliding frame, and each mounting structure is connected to the sliding frame through at least two elastic support structures, and the mounting structures are used to connect and fix the shuttle car body.

[0008] Further, the sliding frame includes a longitudinal rod and three cross rods, the three cross rods are evenly distributed on the longitudinal rod, the end of each cross rod is correspondingly connected to one adjusting mechanism, and the elastic support structure penetrates through the cross rod.

[0009] Further, the elastic support structure includes a support screw, a fixing nut, a buffer spring and two buffer rubber blocks. The top of the support screw is connected to the mounting structure. The support screw penetrates through the cross bar. The fixing nut, the buffer spring and the two buffer rubber blocks are all arranged on the support screw. The two buffer rubber blocks are located above the cross bar. The buffer spring and the fixing nut are located below the cross bar. The fixing nut is used to compress the buffer spring.

[0010] Further, the guiding roller structure includes a roller housing, a fixing plate and a plurality of moving rollers. The upper end surface of the roller housing is connected to the adjusting mechanism through the fixing plate. The plurality of moving rollers are arranged inside the roller housing.

[0011] Further, the adjusting mechanism includes an adjusting bolt and two locking nuts. The adjusting bolt penetrates through the fixing plate. The two locking nuts are both arranged on the adjusting bolt. The inner end of the adjusting bolt is in threaded cooperation with the end of the cross bar.

[0015] 1. Through the cooperation of the buffer spring and the buffer rubber blocks, the elastic support structure can effectively absorb and relieve the impact force and vibration generated during the operation of the shuttle car. Especially when starting, stopping or passing through an uneven track, the elastic support can significantly reduce the impact on the equipment, protect the guiding structure and the shuttle car body, and extend the service life of the system. The elastic support structure can dynamically adjust the attitude of the shuttle car, compensate for minor alignment deviations, and ensure the smooth operation of the shuttle car on the track. Even if there are slight unevenness or installation errors in the guide rail, the elastic support structure can adapt through elastic deformation to avoid the shaking and jamming of the vehicle body. Since the elastic support structure can effectively buffer the impact and vibration of the equipment, reduce the hard collision between components such as rollers and slide rails, thereby reducing friction and wear, extending the service life of rollers, guide rails and other components, and reducing the maintenance frequency and cost.

[0016] 2. The adjustment mechanism has a simple structure. The design of the distance adjustment bolt and the locking nut facilitates the operator's daily maintenance or replacement of damaged rollers. By loosening the locking nut, the rollers can be easily adjusted or replaced without the need for complex tools or operations. The adjustment mechanism enables the shuttle car to adapt to track systems of different specifications or states. Especially in multi-layer warehousing or under track conditions in different environments, by adjusting the position of the rollers, it can adapt to different guide rail widths or shapes. The adjustment mechanism can ensure that the rollers are always in the best contact state with the guide rail, avoiding derailment of the rollers due to external impacts or track changes during operation, and improving the safety and stability of the system.
