Description

Technical Field

[0001] This utility model relates to the field of aerial vehicle technology, specifically to an elastic guide wheel structure for an aerial vehicle. Background Technology

[0002] The aerial trolley is an autonomous mobile material handling device that travels along a track loop. Its conveying scheme can be planned by using a non-ground space layout, which can transfer the material conveying from a two-dimensional layout to a three-dimensional layout. It can realize a multi-line parallel planning scheme in the same spatial layout, and better improve the space utilization rate.

[0003] The track of the aerial vehicle is laid out in the air, and the track line is generally designed to be fixed by monorail suspension. When the aerial vehicle runs along the laid-out track, the movement of the aerial vehicle needs to be guided and restricted by the guide wheel structure to ensure the normal operation of the aerial vehicle. In order to ensure reliable guidance for the movement of the aerial vehicle, the guide wheel structure is usually used to clamp the track to ensure that the movement of the aerial vehicle has a sufficiently reliable guiding restriction. Generally, the guide wheel structure is installed on the fixed frame structure of the vehicle body. This approach can better ensure the limiting and guiding function of the guide wheel through forced limiting, so that the aerial vehicle has reliable track-keeping ability when it travels along the track.

[0004] However, this approach has a drawback: the guide wheel structure, with its strong positioning limitations, has poor adaptability to curves when traveling along the track. The width of the guide wheel structure along the track, i.e., the distance between the two guide wheels within the structure, is directly proportional to the minimum turning radius of the track. The larger the distance between the guide wheels, the wider the guide wheel structure, and the greater the minimum turning radius it can accommodate. Conversely, the smaller the guide wheel structure, the smaller its width, and the weaker its guiding ability.

[0005] In summary, to ensure sufficient guiding capability, the guide wheel structure requires adequate structural width. However, further reducing the minimum turning radius of the track would prevent the guide wheel structure from properly conforming to the track, thus reducing its guiding capability. Based on the key analysis of the fixed aerial trolley guide wheel structure above, a new type of guide wheel structure is developed. While ensuring sufficient guiding capability, the track adaptability of the guide wheel structure is further expanded, forming a standardized and universal structure. Utility Model Content

[0006] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide an elastic guide wheel structure for an aerial vehicle. The elastic guide wheel structure for the aerial vehicle includes a structural fixing seat, a spring damping assembly, and fixing bolts. The spring damping assembly is a component used for elastic load-bearing structure. The spring damping assembly consists of a spring damping rod, a support swing rod, a guide wheel, a spacer, and a guide wheel axle. One end of the spring damping rod is connected to the support swing rod, and the other end is fixed to the axle at the end of the structural fixing seat. The elastic expansion and contraction of the structure is achieved through the spring damping rod to enable adaptive adjustment of the overall structure.

[0007] Preferably, the structural fixing seat is the main load-bearing structural component of the entire mechanism. It is clamped and fixed by welding two sheet metal pieces together with a bent sheet metal piece, and the two sheet metal pieces are welded to the ends and the middle with shafts to connect and fix the spring damping assembly.

[0008] Preferably, one end of the support arm is fixed to the shaft in the middle of the structural fixing seat, and the other end is connected to the spring damping rod. The support arm is a sheet metal part with a shaft hole, and it also has a threaded hole to connect and fix the guide wheel shaft.

[0009] Preferably, the guide wheel shaft is a shaft component used to fix the guide wheel, with one end having a thread for connection and fixation, and the other end having a shoulder for fixing the guide wheel bearing and structural fastening.

[0010] Preferably, the guide wheel is a polyurethane-coated wheel with built-in bearings, which is directly connected and fixed to the support swing arm through a spacer and a guide wheel shaft. The guide wheel is in direct contact with the track and bears a certain radial force, thus guiding the direction of the aerial trolley. Beneficial effects

[0011] 1. This aerial trolley's elastic guide wheel structure optimizes the design of the fixed guide wheel structure by changing its wheel assembly fixing structure to a spring-pressed structure. By using a buffer spring in conjunction with a swing arm, the guide wheel is tightly pressed against the aluminum profile track, ensuring its guiding capability. While the spring damping structure can ensure a tight fit of the guide wheel, its guiding capability is weaker than the fixed guide structure due to its rebound buffering effect. To further ensure the aerial trolley's guiding capability, the aerial trolley's structural design uses the aforementioned spring damping method on one side of the guide wheel structure near the inner ring, while the other side uses a fixed guide wheel structure in conjunction, further guaranteeing the structure's guiding capability.

It is directly connected and fixed to the support swing arm through the spacer 7 and the guide wheel shaft 6. The guide wheel 8 is in direct contact with the track and bears a certain radial force, thus guiding the direction of the aerial trolley.

[0023] It should be noted that the elastic guide wheel structure of this aerial trolley is an adaptive guide wheel clamping track mechanism using a spring damping structure. This structure includes a structural fixing seat 1, a spring damping assembly 2, and related fixing bolts 4. The structural fixing seat 1 is the main load-bearing structural component of the entire mechanism. Its main feature is that it uses a bent sheet metal piece welded with two sheet metal pieces for clamping and fixing. A shaft 3 is welded to both ends and the middle of the two sheet metal pieces to connect and fix the spring damping assembly 2. The spring damping assembly 2 is the main component for elastic load-bearing structure, consisting of a spring damping rod 9, a support swing rod 5, a guide wheel 8, a spacer 7, and a guide wheel shaft 6.

The spring damping structure ensures that the guide wheels provide sufficient guiding capacity. The elastic adaptive structure ensures reliable guidance for the aerial vehicle on both curves and straight sections as it travels along the track. Furthermore, the spring damping structure can absorb vibrations during the vehicle's movement to a certain extent through its structural characteristics. In addition, this design scheme can further expand the structural adaptability, thereby reducing design complexity and further improving the standardization and modularity of the aerial vehicle.
