Rail transport device of car shell

Abstract

The invention discloses a rail transport device of a car shell. The rail transport device comprises a front wheel frame, a rear wheel frame and two balance rods, wherein two T-shaped wheels matched with two tracks respectively are arranged at the bottom of each of the front wheel frame and the rear wheel frame; the balance rods are arranged along the tracks and can generate elastic bending deformation of a certain angle, and the angle is determined by the length between the two connecting points of the balance rods and the maximum height difference of the tracks in the same position; a supporting column is arranged on the upper plane of each of the two ends of each of the front wheel frame and the rear wheel frame, compression springs are arranged between the supporting columns and the front wheel frame and between the supporting columns and the rear wheel frame, a U-shaped supporting block with an upward opening is arranged at the top end of each supporting column, and the U-shaped grooves of the U-shaped supporting blocks are matched with the bottom cross beams of the car shell. Therefore, the derail accident of the rail transport device caused by suspension of the T-shaped wheels can be prevented.

Description

technical field [0001] The invention relates to a transportation device, in particular to an automobile body rail transportation device. Background technique [0002] The traditional automobile body rail transportation device includes a rigid underframe for carrying the automobile body. The bottom of the underframe is provided with four rectangularly arranged T-shaped wheels that are respectively matched with two rails. When walking, the flanges of the T-shaped wheels block the rails on both sides to prevent the derailment of the car body rail transport device. Because the assembly process of passenger cars is relatively complicated and needs to go through multiple processes, the track of the car body rail transport device is correspondingly long. After long-term use of the track, it is easy for two tracks to be in the same position due to the wear and tear of the track surface and partial shedding. There is a height difference, and when the car body rail transport device p...

Problems solved by technology

Because the assembly process of passenger cars is relatively complicated and needs to go through multiple processes, the track of the car body rail transportation device is correspondingly long. After long-term use of the track, it is easy for two tracks to be in the same position due to the wear and tear of the track surface and partial shedding. There is a height difference, and when the car body rail transport device passes by here, since the three T-shaped wheels can form a plane, and the underframe is rigid, there must be a wheel suspended in the absence of external force. , if the height of the suspension is greater than the flange of the T-shaped wheel, a derailment accident may occur. Although these track defects will be repaired or replaced during regular track inspections, there are still hidden dangers that are not conducive to safe production
