Ballast changing pillow machine

Abstract

The invention relates to a high-efficiency ballast-raking sleeper changing machine. The high-efficiency ballast-raking sleeper changing machine comprises a railway car (1) rotatably provided with railwheels (11). The railway car (1) is provided with front and rear sleeper grasping hangers (3) and front and rear ballast raking devices (4), each ballast raking device separately comprises a verticalsliding body (41) and a ballast raking plate (42), the vertical sliding main body is slidably mounted on the railway car in the vertical direction, and a high-frequency vibrator (5) is mounted on thevertical sliding body. A ballast raking plate base is slidably installed at the bottom of the vertical sliding body, the ballast raking plate base of the front ballast raking device is provided withtwo sleeper shifting rods (45), the ballast raking plate base of the rear ballast raking device is provided with two sleeper hooks (46), the tail ends of the two sleeper hooks are hinged to the ballast raking plate base, and hook rail hydraulic cylinders (47) are separately arranged between the head ends of the two sleeper hooks and the ballast raking plate base. According to the high-efficiency ballast-raking sleeper changing machine, the manpower is saved when the sleeper is replaced, sleeper replacement speed is high, working efficiency is high, and time is saved. The high-efficiency ballast-raking sleeper changing machine has low damage to the rail and ballast foundation, the rail is not cut, and disturbance to the ballast foundation at the bottom of the rail is less.

Description

technical field [0001] The invention relates to railway machinery, in particular to a sleeper changing machine for replacing railway sleepers. Background technique [0002] The railway department replaces the sleepers during the running time of the train. For the staff of the railway bureau, replacing the sleepers is a job that requires high speed and efficiency, so as not to affect the normal operation of the train. At present, the method of replacing sleepers in the railway department is still mainly manual work, which is very labor-intensive, slow and inefficient. People's endurance is limited, in order to speed up the replacement speed, in order to replace as many sleepers as possible in a driving gap, multiple people are required to work in rotation, the labor cost of replacing sleepers is very high, and the labor intensity of workers is also very high. Although there have been large-scale machines for replacing sleepers in foreign countries, their structures are compl...

AI Technical Summary

Problems solved by technology

At present, the method of replacing sleepers in the railway department is still mainly manual work, which is very labor-intensive, slow and inefficient.

Human endurance is limited. In order to speed up the replacement speed and replace as many sleepers as possible within one driving gap, multiple people are required to rotate. The labor cost of replacing sleepers is very high, and the labor intensity of workers is also very high.

Although there have been large-scale machines for replacing sleepers in foreign countries, their structures are complex and costly, and the cost of use is also relatively high. Each operation requires cutting the rails and then welding them again. , It takes a long time to prepare for the operation during the blockade, which is not suitable for the national conditions of the tight capacity of most railway lines in my country and the short blockade maintenance time
