Catenary anti-tipping operation ladder vehicle for railway vehicle

Abstract

The invention discloses a catenary anti-tipping operation ladder vehicle for a railway vehicle. The catenary anti-tipping operation ladder vehicle comprises rails, a plurality of rolling devices are installed on the rails, each rolling device comprises a connecting rod spanning between the rails, rotatable wheels are fixedly installed at two ends of each connecting rod, and brake mechanisms are arranged on the wheels; and an anti-tipping device is arranged on the rail on the outer side of any wheel, the anti-tipping devices are detachably connected with the rolling devices, two adjacent connecting rods are fixedly connected through a chassis device, a vertical supporting rod is detachably arranged on the chassis device, and a liftable working platform is arranged at the upper end of the supporting rod. The ladder vehicle is provided with the brake mechanisms and the anti-tipping devices, the anti-tipping devices can be selectively installed on the left side or the right side of the corresponding brake mechanisms according to the condition of the guide rail, some turnout positions are avoided, the turnout tip and the guide rail can be locked at the same time, and the ladder vehiclecan be used at various crossed rails, turnouts and other positions.

Description

technical field [0001] The invention relates to the technical field of rail vehicle construction, in particular to a catenary anti-tipping operation ladder car for rail vehicles. Background technique [0002] The ladder car is an indispensable and important equipment for the construction and maintenance of electrified railways. At present, there are many defects when the ladder car is used for the maintenance of the railway track system, as follows: [0003] 1. It is inconvenient to install on the rail, and it is also inconvenient to remove from the rail or place it on another rail. [0004] 2. Lack of anti-tipping device. In the position where there is no cross rail, the operation ladder car on the rail can be locked through a simple structure, but the existing locking device cannot be used at the turnout and the intersection of multiple rails. . But in reality, the more the railroad tracks cross, the more work there is. In order to ensure the safety of workers working at...

AI Technical Summary

Problems solved by technology

[0003] 1. It is inconvenient to install on the rail, and it is also inconvenient to remove from the rail or place it on another rail

[0004] 2. Lack of anti-tipping device. In the position where there is no cross rail, the operation ladder car on the rail can be locked through a simple structure, but the existing locking device cannot be used at the turnout and the intersection of multiple rails.

But in reality, the higher the position where the rails cross, the more work there is. To ensure the safety of workers working at heights, only six or seven people can hold the ladder car from around to prevent it from tipping over.

[0005] 3. The height of the ladder car itself cannot be adjusted. The height of the catenary is different for different railways. At the same time, the individual heights of the construction workers are different, and the heights of the construction positions are different.

[0006] 4. During construction, there is nowhere to install the safety belts of the workers

When going up and down the ladder, the seat belt cannot be fastened on the ladder car, so personal safety cannot be guaranteed

[0007] 5. It is inconvenient to transport (tools) work in the up and down direction of the ladder car

[0008] 6. The ladder car itself cannot be disassembled or folded, and it is troublesome to transport and carry. Due to the length, it can only rely on large trucks, which increases the transportation cost

[0009] 7. The working range of the working bucket is very small, limited to the working bucket, but during construction, it is often necessary to exceed the moving range of the working bucket of the ladder truck. The current method usually uses wooden strips to widen the moving range of the operator, which brings great big security risk

[0010] 8. It is inconvenient for the ladder car to pass through the turnout and the fish plate

[0011] 9. When the ladder car is assembled, installed on the rail, removed from the rail, and moved to another location, it must meet the conditions of rapid disassembly and assembly. There is a problem of cross-construction mutual influence. When the tunnel construction party is carrying out transportation operations, it is necessary to remove the ladder truck to facilitate the passage of transportation vehicles
