Description

Technical Field

[0001] The invention belongs to the technical field of railway transportation equipment, and in particular relates to an unloading guide operation trolley for a special train set for long rail transportation. Background Art

[0002] The T11 series long rail trains are special trains for laying railway lines in my country. They are divided into T11A, T11B, T11BT and T11BK types. The main differences are in the bogies and operating parts. In recent years, through upgrading and transformation, all the railway freight cars currently in use are T11BK long rail trains. This train is mainly responsible for the loading, transportation, unloading and recycling of welded long rails. The rail loading method of the train set adopts horizontal lifting, the rail unloading method adopts longitudinal unloading on both sides, and the rail collection method adopts the method of reverse train from the rear of the train to shovel the old rails onto the train using the rail collection trolley.

[0003] The existing T11 series long rail car formation mainly includes: power generation car → safety car (one) → rail transport car (8 cars) → anti-rollover car (one) (1 car) → anti-rollover car (two) (1 car) → rail transport car (6 cars) → locks (one), (two), (three), (four) → rail transport car (6 cars) → anti-rollover car (one) (1 car) → anti-rollover car (two) (1 car) → rail transport car (7 cars) → safety car (two) → first car for operation → middle car for operation (one) → middle car for operation (two) → middle car for operation (three) → last car for operation. The main devices for realizing rail collection and unloading operations are set on the first car for operation, middle car for operation (one), middle car for operation (two), middle car for operation (three), and last car for operation. The main equipment and devices involved are: hydraulic conveyor, hydraulic winch, operating table, hydraulic station, hydraulic system, microcomputer controlled rail unloading system, clamp return device, rail collection device, rail unloading roller device, rail pull device, etc. There are many devices and complex structure.

[0004] During the track closing operation, the train needs to be reorganized, the middle car (three) and the tail car are swapped, the detachable transition plate at the tail of the middle car (three) is removed, and the transition plate of the tail car is installed, or the tail car is removed. The operation is complicated, inefficient, and subject to certain conditions.

[0005] The tail car is set at the rear end of the train set and is used for rail unloading, rail collection operations and crew camping. The upper part of the car body is designed with reference to the 25B passenger car body, with a driver's room and two berths. In addition to the living equipment for the personnel, there are also power distribution cabinets and charging equipment. There are rail unloading channels, height adjustment rail deflectors, hydraulic rail deflectors, etc. on both sides of the car. The car has many equipment and complex structure, and the manufacturing, repair and maintenance costs are high. During unloading operations, it can only be unloaded to the center of the track, and when the rail is unloaded, the end of the rail falls directly to the ground, which is easy to damage the rail or smash accessories such as sleepers.
