Traveling wheel mechanism with automatic lifting function and for rail trolley

Abstract

The invention relates to a traveling wheel mechanism with an automatic lifting function and for a rail trolley. The walking wheel mechanism has an advancing function, a hydraulic lifting function anda fastening limiting function, and can achieve safe and reliable advancing, ascending, descending and fastening limiting between the rail trolley and an H-shaped rail. The traveling wheel mechanism comprises an advancing structure, a hydraulic lifting structure and a fastening limiting structure; the advancing structure comprises an advancing wheel matched with the H-shaped rail; the hydraulic lifting structure comprises a hydraulic oil cylinder used for driving the advancing wheel to ascend or descend to be separated from or make contact with the H-shaped rail; when the traveling wheel is incontact with the H-shaped rail, the rail trolley is supported on the H-shaped rail through the traveling wheel, and at the moment, the rail trolley is in an advancing state; when the traveling wheel is separated from the H-shaped rail, the rail trolley is supported on supporting frames on the two sides of the H-shaped rail, and the rail trolley and the supporting frames are fastened and limited through the fastening limiting structure, and at the moment, the rail trolley is in a fastening limiting state.

Description

Technical field [0001] The invention relates to a traveling wheel mechanism, in particular to a traveling wheel mechanism with an automatic lifting function, and belongs to the technical field of mechanical design. Background technique [0002] A certain type of equipment needs to undergo a series of environmental tests. Before the test, the equipment is placed on the rail trolley by a crane, and then the rail trolley is transported along the I-shaped track to a specific location in different environmental test boxes for corresponding tests. Assess the environmental resistance function and performance of the equipment. [0003] Due to the heavy weight of this type of equipment, and the need to continuously switch the equipment at high speed for a long time during the test, the inertial impact force is very large; at the same time, the rail trolley carrying the test equipment needs to be frequently moved to the corresponding position during the test. . If the limit cannot be safel...

AI Technical Summary

Problems solved by technology

However, the disadvantage of rubber tires is that they are large in size, so that the height of the trolley is high, so that the center of gravity of the equipment is high, and the rubber tire itself is easily affected by the corrosion of oil, the impact of changes in the test environment, and the alternating vibration and shock generated when the equipment is running at high speed. Due to the action of force, the tire will suddenly fail during the whole process of the environmental test

In addition, rubber tires are prone to derailment when traveling on I-shaped tracks.

This situation will also bring great potential safety hazards to test equipment, test testing equipment and personnel.
