Description

Technical Field

[0001] This utility model relates to the field of heavy-duty elevator technology, and more specifically, to a multi-platform self-moving heavy-duty elevator. Background Technology

[0002] An open-pit coal mine is a coal mine that uses open-pit mining technology, where mining is carried out directly from the surface. This mining method involves stripping away the rock and soil surrounding the coal seam, and then excavating layer by layer from the surface until a large pit is formed. Open-pit mining is relatively economical. The soil above the ore seam is called rock and soil. Explosives are pre-buried in the undeveloped rock and soil zone, and after blasting, excavators, trucks, and other equipment are used to remove the topsoil. The topsoil is transported to spoil heaps (internal and external spoil heaps). After the topsoil is removed, the coal seam is exposed. The coal seam is then crushed, and coal is transported to a coal preparation plant for washing and processing using mining trucks.

When the mine car enters the top of the rotating module 3, the lifting platform of the lifting module 2 is raised and lowered by the four hydraulic devices of the lifting module 2, so that the mine car can reach different platforms. The direction of the mine car can be changed by rotating the rotating module 3, so that the mine car can travel in multiple directions. The multi-platform mechanism 4, which is composed of multiple platform units 41, can be quickly and conveniently assembled and disassembled, improving the efficiency of subsequent maintenance.
