Abstract

The invention discloses a stacker fork mechanism which comprises a bearing mechanism and a fork mechanism. The fork mechanism further comprises a lower fork, a middle fork and an upper fork, wherein the bearing mechanism and the lower fork are both fixed on a beam of a stacker. When the stacker runs to a designated goods location, bearing steel rails are driven by a reducing motor A to translate toward a shelf to be accurately abutted with the steel rails on the shelf. Then the middle fork moves on the steel rail of the lower fork; a telescopic shaft of the upper fork is extended out to seize the flanges of the wheels of a bogie and push the bogie toward the shelf so as to complete the storage operation. When the operation is completed, the bearing steel rails on a loading platform translate inversely to an original position on the loading platform. The fork mechanism pushes the bogie to move and bears the gravity load of the bogie through the bearing steel rails, thereby bringing about a simple structure and light mass for telescopic forks. The motion and storage is realized through the running of the wheels of the bogie, thereby saving the cost for a special-purpose pallet.

Description

technical field

[0001] The invention relates to the technical field of mechanical manufacturing, in particular to a stacker fork mechanism used for bogie access. Background technique

[0002] In order to meet the ever-increasing demand for transportation from the rapid development of the national economy and society, my country's railways have established a development plan for the railway rapid passenger transport network, introduced four types of EMUs, and decided to establish modern EMUs in Beijing, Shanghai, Wuhan, and Guangzhou Overhaul base. In the motor vehicle maintenance base, there are inspection and maintenance depots, high-level maintenance depots, and bogie maintenance depots for disassembling and overhauling bogies. In order to meet the requirements of bogie maintenance, it is necessary to set up a three-dimensional storage warehouse for bogies in the bogie maintenance warehouse.

[0003] The fork mechanism is the executive mechanism for the storage and retrie...
