Electromagnetic hoisting equipment for the roof skin of the minibus

Abstract

The invention relates to electromagnetic hoisting equipment of a minibus total roof skin, which comprises a hanger assembly, four steel wire ropes, four electromagnets and four fixing blocks, wherein the hanger assembly is a rectangular framework; hooks are respectively arranged at the four corners of the hanger assembly; the steel wire ropes are in one-to-one correspondence with the hooks; the first end part of each steel wire rope is connected with the corresponding hook; each electromagnet is connected with the second end part of the corresponding steel wire rope; the fixing steel blocks are arranged on the upper surface of the roof skin; and the fixing steel blocks are in one-to-one correspondence with the electromagnets in position. The electromagnetic hoisting equipment of a minibus total roof skin with the structure can hoist the roof skin assembly by use of the electromagnetic adsorption principle; when the roof skin is hoisted, greater deformation is avoided, and the surface smoothness of the skin is not damaged; and moreover, the equipment realizes stable and convenient hoisting and placing processes, is favorable for assembly, and has a simple structure and a wider application range.

Description

technical field [0001] The invention relates to the field of production and manufacturing of minibuses, in particular to the field of hoisting during the production and manufacturing of minibuses, and specifically refers to an electromagnetic hoisting device for the roof skin of a minibus. Background technique [0002] In the production and assembly process of minibuses, the top skin assembly is made of 9 pieces of pressed parts, the front 1, 2 and the last section are integral pressed parts, and the middle and front sections and the middle and rear sections are made of three parts in the middle and two sides. Block press-formed parts, made by contact welding. A common vehicle currently on the market has a top skin with a length of 6530mm and a width of 1735mm. The roof skin assembly has a relatively high arch height of 380mm. The skin material is usually a 1mm thick steel plate. [0003] The usual hoisting method is to weld 4 U-shaped round steel pieces on both sides of th...

Problems solved by technology

[0004] This kind of hoisting method has the following disadvantages: 1. The force on the four hooks is oblique force, which is easy to deform; 2. The four U-shaped parts are fully welded and easy to deform; 3. The four U-shaped parts are due to the long weld (each The total length of the weld seam of each U-shaped piece is 400㎜), and it is not easy to polish when dismantling; 4. The hook is easy to decouple when hoisting, which affects production safety; 5. When the workpieces are stacked, the four U-shaped pieces take up space
