Multi-functional walking vehicle with self-locking bogie

Abstract

The invention relates to a multi-functional walking vehicle with a self-locking bogie, belongs to the technical field of transportation means in wagon production lines and particularly relates to an improvement of bogie transportation device structures. The walking vehicle comprises a walking vehicle body, an elevation frame and a rotation device, wherein the elevation frame is matched with guide sleeves of the walking vehicle body through guide columns, and the rotation device is arranged above the elevation frame. The walking vehicle is characterized in that supporting columns are arranged at the bottom of the elevation frame through horizontal rotation shafts; and elevation rods are arranged on the walking vehicle body, a top disc is arranged at the upper ends of the elevation rods, and the edge of the top disc corresponds to the supporting columns. The multi-functional walking vehicle is stable in operation and good in safety.

Description

technical field [0001] The invention belongs to the technical field of transport tools for railway wagon production lines; more specifically, the invention relates to an improvement in the structure of a bogie transport device. Background technique [0002] The bogie is composed of a bolster and two side frames; both the bolster and the side frames are the main components of the running part of the railway freight car; it needs to be assembled with spring wedges, cross bar assembly, cross bar welding, orthographic testing, Brake beam assembly, lower rod, lever, cross beam assembly, and load saddle assembly process. [0003] At present, the bogie is usually hoisted by the crane between the assembly processes; this method has the following disadvantages: 1. The crane hoisting is relatively dangerous. Once the bogie falls, production safety accidents are prone to occur. [0004] 2. When the steering frame of the crane crane falls to a specific station, its falling position is ...

AI Technical Summary

Problems solved by technology

[0003] At present, the bogie is usually hoisted by the crane between the assembly processes; this method has the following disadvantages: 1. The crane hoisting is more dangerous. Once the bogie falls, production safety accidents are prone to occur

[0004] 2. When the steering frame of the crane crane falls to a specific station, its falling position is inaccurate; the production accuracy cannot be guaranteed

[0005] 3. During transportation, since the bogie is perpendicular to the transportation line, it occupies a large area

[0008] In addition, the structure of the locking device is complicated, and it is welded as a whole by the plate, so there are many places that are prone to damage. Due to the heavy weight of the bogie, the positioning block is subjected to shear force for a long time, and it is difficult to ensure the safety of long-term use.
