Freight lift car frame device

Abstract

The invention relates to a freight lift car frame device which is used for large-tonnage lift loading. The freight lift car frame device comprises a main lift car frame (1), secondary lift frames (2), transverse beam channel steel (3) and pull bar screw rod assemblies (4), wherein the main lift car frame (1) comprises a main upper beam assembly (1-1), a car top wheel assembly (1-2), a main vertical beam assembly (1-3) and a main lower beam assembly (1-4); each secondary lift frame (2) comprises a secondary upper beam assembly (2-1), a secondary vertical beam assembly (2-2) and a secondary lower beam assembly (2-3); assemblies forming the main lift car frame (1) and the secondary lift frames (2) form an integral structural framework through bolts; the transverse beam channel steel (3) penetrates through the main lift car frame (1) and the secondary lift frames (2); and the pull bar screw rod assemblies (4) are arranged at the two sides of the main lift car (1) and those of the secondary lift frames (2). The device disclosed by the invention is mainly divided into one main car frame and two secondary car frames; and the total weight of a lift car are shared to three car frames so as to reduce bad influences caused by partial offset load on a guide rail, guide shoes and the like. Each one of the main car frame and the secondary car frames is formed by the related upper beam assembly, the related vertical beam assembly, the related lower beam assembly and the like, and the main car frame and the secondary car frames are strengthened and fastened by the transverse beam channel steel; and vertical beams of all the car frames are connected with a lift car supporting frame through the pull bar screw rod assemblies so that the structure of a lift is more stable. The freight lift car frame device is simple and reliable in structure and can be applicable to large-tonnage freight lifts.

Description

technical field [0001] The invention relates to a large-tonnage freight elevator car frame arrangement. Background technique [0002] Freight elevators, as the name suggests, are elevators used to transport goods. Due to its narrow and long structural features (the depth of the car is generally greater than the depth), it is convenient for loading and unloading goods. Especially when the elevator is used in a large-tonnage structure, when transporting goods with a trailer, it often does not stop completely in the middle of the car, which will concentrate the load on one side, causing the car to generate a large partial load. The conventional car frame The structure has been unable to meet the strength requirements in this case. Contents of the invention [0003] The technical problem to be solved by the utility model is to provide a car frame layout, which can effectively reduce the impact of the heavy load on the elevator when the large-tonnage freight elevator is used....
