Long steel rail transport loading and unloading vehicle and transportation vehicle set composed thereof

Abstract

The invention discloses a long steel rail transportation loading and unloading vehicle and a transportation vehicle set. The long steel rail transportation loading and unloading vehicle comprise a chassis assembly arranged on a wheel set and a bogie. Two sets of steel rail transportation loading fixing mechanisms are respectively arranged along the two sides of the center line of the chassis assembly, and a steel rail unloading mechanism is arranged at the tail end of the chassis assembly; and each steel rail transporting loading fixing mechanism comprises an adjustable support assembly, a steel rail braking device, a transverse roller, a guide rail groove and a rail loading and unloading opening which are sequentially arranged in the axial direction of a chassis. A steel rail unloading system is composed of an unloading operation trolley and a trolley driving guide mechanism of the unloading operation trolley. The transportation vehicle set comprises a blocking vehicle, a loading andunloading vehicle, a clamping vehicle, two transition vehicles, four bearing vehicle set units and a spanning type lifting vehicle which are connected. The transportation loading fixing mechanisms canadjust the height of the steel rail and lift the operation trolley to improve the operation automation degree, safety and stability and can match the height needed during steel rail unloading to meetthe requirement for multi-layer steel rail unloading; and the extending distance of the unloading operation trolley as well as the operation space is reduced.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of railway transport equipment, and in particular relates to a design and manufacture technology of long rail transport vehicles, which is a railway vehicle integrating driving, transportation and loading and unloading. Background technique [0002] Generally, the long rail transport vehicle group is composed of a blocking car, a clamping car, a transition car and a loading and unloading car. The loading and unloading car is used for loading, unloading and recycling of rails. The rail loading method of the train group adopts horizontal hoisting, the rail unloading method adopts vertical rail unloading on both sides, and the rail closing method adopts the way that the train reverses from the rear of the train to shovel the old rails onto the train. At present, the existing long steel rail transport vehicles in China have poor rails, guides, and fixing devices, which are complex in op...
