The design key point of various conveying lines serving as storage logistics core equipment is that goods are accurately conveyed to each station of a stereoscopic warehouse at high speed according to production arrangement requirements.

For example, the currently commonly used dual-circular-track shuttle car is based on full-automatic storage systems in the home appliance industry, the intelligent manufacturing industry, the textile industry and the like, and mainly adopts driving modes such as chain conveying or roller conveying and the like, so that the dual-circular-track shuttle car has the following defects: 1. the scheduling efficiency of the stereoscopic warehouse and the workshop is low, redundancy exists, and matching operation cannot be well carried out; 2. the annular track needs to simultaneously operate a plurality of shuttle cars, and the existing shuttle car conveying line has lower operating speed and limited conveying capacity, thereby restricting the transport capacity level and efficiency of the existing conveying line system; 3. when the existing shuttle car enters a bend, the outer wheel and the inner wheel cannot be synchronized due to the change of the curvature radius, so that the outer wheel slides outwards from the guide rail, the highest speed of the straight-line section and the bending section is limited, the balance performance is poor, and the shuttle car is not suitable for carrying heavy goods. Particularly, the speed is reduced when the angle is over bent, and the overall operation efficiency is low.

In view of this, the present patent application is specifically proposed.

Detailed Description

Example 1, as shown in fig. 1, the high-speed double-track endless shuttle running on a double endless track 1 includes a carriage assembly 2, a conveyor assembly 3, a running wheel assembly 4, and a driven wheel assembly 5.

Wherein, frame subassembly 2 plays main supporting role in order to bear other parts of shuttle, and conveyor components 3 is installed in frame subassembly 2 top in order to realize the butt joint material and the function of transferring the goods between different stations, like realizing the warehouse-out or putting in storage of goods material. The double-annular track 1 bears the body and the load of the shuttle vehicle, and the shuttle vehicle runs on the double-annular track 1 at a high speed through the walking wheel assembly 4 and the driven wheel assembly 5. The driven wheel assembly 5 can adopt a deep groove ball roller bearing as a rotating pair to play a role in guiding two sides of a track, so that the shuttle car body is ensured to always keep running on a guide rail.

The running wheel assembly 4 has a support shaft 40, a drive motor 41, a cross roller bearing 42, a single row angular contact bearing 43, running wheels 44 and a cantilever beam 46.

A cantilever beam 46 is transversely mounted on the bottom end of the support shaft 40, and the cantilever beam 46 has a hollow integral frame structure formed by welding high-strength steel plates.

The wheel shaft 45 of the walking wheel 44 transversely penetrates through the cantilever beam 46 and the walking wheel 44 is installed at the shaft end, the driving motor 41 can be a three-phase asynchronous alternating current motor or a servo motor, and the surface of the walking wheel 44 is coated with rubber so as to be suitable for rolling on the double-ring track 1 made of aluminum alloy materials, so that the effects of increasing friction force and reducing noise can be achieved.

Furthermore, a hollow cantilever shaft 47 is horizontally and transversely arranged on the cantilever beam 46, the outer periphery of the wheel shaft 45 of the traveling wheel 44 is sleeved on the cantilever shaft 47 through at least two groups of single-row angular contact bearings 43, and the wheel shaft 45 penetrating through the cantilever shaft 47 is connected with an output shaft of the driving motor 41.
