Abstract

The invention discloses a non-welded car frame. The non-welded car frame comprises a car platform assembly, a stand column assembly, an upper cross beam assembly and a first guide roller assembly, and further comprises a plurality of fixing members, wherein the stand column assembly is provided with a plurality of first assembling parts; and each of the car platform assembly, the upper cross beam assembly and the first guide roller assembly is provided with a second assembling part, and the plurality of fixing members are used for fixing the first assembling parts and the second assembling parts so as to assemble the car platform assembly, the upper cross beam assembly and the first guide roller assembly on the stand column assembly. The stand column assembly, the car platform assembly, the upper cross beam assembly and the first guide roller assembly are assembled through matching among the fixing members, the first assembling parts on the stand column assembly, and the second assembling parts on the car platform assembly, the upper cross beam assembly and the guide roller assembly, and no welding is used in the assembling process, thus the troubles in factory manufacture and layout caused by welding of multiple parts and large parts are avoided.

Description

technical field [0001] The invention relates to a car frame structure for an elevator, in particular to a car frame structure without welding. Background technique [0002] The car frame is mainly responsible for carrying people and goods in the elevator, and is the main load-bearing part of the elevator. At present, the car frame structure of the elevator adopts a welded structure, and the car floor, columns, upper beams, etc. adopt an integral welded structure. However, the welded structure of the car frame causes problems such as complex manufacturing process in the factory, large welding site, high processing intensity for workers, and difficulties in handling, packing, and on-site installation. Contents of the invention [0003] Based on this, the present invention overcomes the assembly defects of the existing welded structure and provides a non-welded car frame structure, so that the elevator car frame can be used in various links such as factory manufacturing, fac...
