Air roller bed conveyor line

Abstract

The invention discloses an air roller bed conveyor line. The air roller bed conveyor line comprises fixed air roller beds and lifting devices arranged on the fixed air roller beds through skids in an erected mode, wherein the fixed air roller beds include two fixed roller beds which are parallel to each other, and rolling wheels driven by driving devices are arranged on the fixed roller beds. Each lifting device comprises an n-shaped frame, a bracket and the skids, wherein the bracket is arranged at the bottom of the n-shaped frame, and the skids are arranged on the two sides of the n-shaped frame. The air roller bed conveyor line provides insufficient operation space for assembly operators at the bottom of a passenger car. Meanwhile, the lifting devices loaded with the passenger car through the skids are directly arranged on the fixed air roller beds in the erected mode, and a lifting structure is adopted to replace a suspension type structure, so that carrying capacity of the air roller bed conveyor line is promoted; the rolling wheels are adopted to drive the skids to drive the lifting devices to move, so that the passenger car is conveyed more stably, and the potential safety hazards caused by shaking of movable hinges are eliminated; consequently, the problem that an existing conveyor line can not assist in completing bottom assembling of the passenger car is solved.

Description

technical field [0001] The invention relates to the technical field of production lines, more specifically, to an aerial roller conveying line. Background technique [0002] The bottom assembly of the bus is a difficult point in the bus manufacturing process. Many bus factories use trenches for production operations, and employees need to drill into the trenches to operate. However, limited by the width of the trench, the range of activities of employees is severely restricted, the operation is inconvenient, and the ergonomics are not good; the light in the trench is not good, which affects the safety of the working environment. [0003] The chassis assembly of the car adopts a three-rail suspension accumulation chain conveyor line, which can lift the car body to a height of 1.6-1.8 meters from the ground, so that the assembly staff can assemble parts at the bottom of the car body. The three-track suspension accumulation chain conveyor line is composed of two load-carrying ...
