Telescopic device used for railways of electric monorail transportation system

Abstract

The invention relates to a telescopic device used for railways of an electric monorail transportation system. The telescopic device is arranged at the gap position of two sections of railways and comprises a first connection piece, a second connection piece, a sliding block and a guide block. The first connection piece and the second connection piece are connected to the two sections of railways respectively. The sliding block is fixed to the top of the first connection piece, the guide block is fixed to the top of the second connection piece, the sliding block is mutually meshed with the guide block, and the edge of the sliding block and the edge of the guide block are flush with the edges of the railways. Compared with the prior art, the telescopic device used for railways of the electric monorail transportation system can reduce influences of expansion and contraction on the railway operation without increasing cost, and the telescopic device is convenient to adjust and install.

Description

technical field [0001] The invention relates to a telescopic device, in particular to a telescopic device used for the track of an electric monorail transportation system. Background technique [0002] At present, many domestic automobile factories will use electric monorail transportation system, that is, self-propelled trolleys, which are used to accumulate and transport workpieces to improve production efficiency and automation. Its track is one of the most important components in the electric monorail transportation system, carrying all the self-propelled trolleys running on it. In order to reduce noise and improve the safety of the self-propelled trolleys, the requirements for the use of the tracks are often very strict. The track route is very long. In order to meet the precision requirements, it is not only necessary to control very precisely during manufacturing, but also not to have too much error during installation, otherwise it will bring noise when the self-prop...

AI Technical Summary

Problems solved by technology

[0003] 1. High cost: In order to meet the above requirements, either use special material rails, and improve the machining accuracy and installation accuracy to a very high level, which can eliminate this problem, but the domestic technology is not mature enough, so many Automobile manufacturers directly adopt foreign technology and foreign products. Although the goal has been achieved, the cost has risen greatly.

[0004] 2. Unsafe: If you do not use foreign products and use domestic manufacturers, then the tracks are often section by section. Due to the harsh working environment in the workshop, under the condition of large temperature difference, the track will expand with heat and contract with cold. , so that there will be a gap or a certain deformation on the joint surface of the track

The result of this is that when the self-propelled trolley passes through this gap, there will be noise, which will seriously affect the operation of the trolley.
