Automatic guide deviation rectifying device of rail transportation device

Abstract

The invention relates to an automatic guide deviation rectifying device of a rail transportation device. The rolling wheels and the tracks are optimally designed, the U-shaped tracks with two rolling contact surfaces and the conical deviation rectifying wheels are adopted, and the situation that the wheels on the left side and the right side are different in advancing speed and distance under the condition of the same rotating speed due to errors in the aspects of friction force, movement resistance, track levelness and the like of the wheels on the two sides can be automatically and effectively counteracted; and the whole device is simple in structure, flexible to assemble and suitable for being used in a walking mechanism of oversized-span rail transportation equipment in the heavy industry.

Description

technical field [0001] The invention relates to the technical field of rail deviation correction, in particular to an automatic guide deviation correction device of a rail transport device. Background technique [0002] Crane is a common name for cranes such as cranes, aerial vehicles, and overhead cranes. Like gantry cranes, cranes are mainly used for lifting and transferring items in warehouses and freight yards. The running mechanism of these equipment mostly adopts the track and roller structure. At present, in the field of cranes, the wheels on the left and right sides of the rail transportation equipment such as the super-span crane and the gantry crane, such as image 3 , Figure 4 In the structure shown, the wheels are mostly cylindrical, and the two ends or inner edges of the vehicle are provided with bosses to prevent derailment. The wheels of this shape structure are due to errors in manufacturing, frictional force, motion resistance, track level, etc. , causing ...

AI Technical Summary

Problems solved by technology

The traveling mechanisms of these equipment mostly adopt the structure of rails and rollers. At present, in the field of mobile cranes, the wheels on the left and right sides of rail transportation equipment such as super-large-span cranes and gantry cranes, such as image 3 , Figure 4 In the structure shown, the wheels are mostly cylindrical, and bosses to prevent derailment are set at both ends or the inner edge of the vehicle. For wheels with this shape, due to errors in manufacturing, friction, movement resistance, and track levelness, etc. , causing the wheels on the left and right sides to travel at different speeds and distances under the same rotational speed conditions, causing the car body to deflect, and in severe cases, it may cause derailment accidents, and there are potential safety hazards in the use process
