Description

Connecting shaft combined structure for transmission of fork plate Technical Field The utility model relates to the technical field of multi-layer shuttling vehicles, in particular to a connecting shaft combined structure for transmission of a fork plate. Background For the multilayer shuttle car that track transportation was used in commodity circulation warehouse, it can be from the fork board that stretches fork goods from taking generally, and the transmission between the fork board relies on the inside structure such as transmission shaft, hookup axle collocation drive chain of dolly generally, and for the hookup axle, if the transportation of dolly exists the environment such as meeting water, it is unavoidable can contact moisture, rust, block and abnormal sound all are the problem that appears easily under long-time operation. As shown in fig. 2 of the specification, the existing coupling shaft is generally of a whole shape, the shaft body is long, and when the coupling shaft is worn after the trolley is used for a period of time and needs to be replaced or maintained, the whole trolley is required to be disassembled or the coupling shaft is required to be installed by rotating 180 degrees, which is tedious and error-prone, and particularly involves aspects such as electrical wiring, therefore, a coupling shaft combined structure for transmission of a fork plate is provided to solve the problems. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides a connecting shaft combined structure for fork plate transmission, which is convenient for the subsequent disassembly, assembly, maintenance or replacement of a connecting shaft. In order to solve the technical problems, the connecting shaft combined structure for the transmission of the fork plates comprises a multi-layer shuttle, wherein the fork plates and chain transmission pieces corresponding to the fork plates are symmetrically arranged at two ends of the top of the multi-layer shuttle, the two chain transmission pieces are transmitted through the combined structure, the combined structure comprises a connecting sleeve, a fixing piece and two linear bearings respectively corresponding to the chain transmission pieces, one end of each linear bearing corresponding to the chain transmission piece is connected through a bearing seat in a rotating mode, the other end of each linear bearing is embedded with the connecting sleeve, and the connecting sleeve is detachably and fixedly connected with the corresponding linear bearing through the fixing piece, and the shaft length of each connecting sleeve is smaller than half of the shaft length of each linear bearing.
