Canopy of railway wagon

Abstract

The invention belongs to the technical field of railway wagons and particularly relates to a canopy of a railway wagon. The canopy comprises a transmission device and a canopy device, wherein the canopy device comprises a fixed frame, a plurality of movable frames and a layer of folding type canvas; the fixed frame and each movable frame are connected by adopting a dragging rope; the fixed frame is fixed at the top part of one end of the wagon; each movable frame consists of a skeleton and a pulley; the skeleton comprises a cross beam, a left supporting leg and a right supporting leg; the lower parts of the two supporting legs of the skeleton are respectively connected with one pulley block by a connecting plate; a plurality of left-side guide-rail lifting seats and right-side guide-rail lifting seats are respectively welded on upper-side beams along the left side and the right side of the wagon at equal intervals, and are connected with a left guide rail and a right guide rail by bolts; the pulley block of each movable frame slides on the corresponding guide rail. The canopy has the advantages that a folding type telescopic structure is adopted, the weight is light, the installation is easy and the operation is easy; the extension and retraction of the canopy are realized by adopting a chain steel rope to drag the pulleys to slide along the guide rails; the high-altitude operation is avoided and the safety is improved.

Description

technical field [0001] The invention belongs to the technical field of railway freight cars, and in particular relates to a roof of railway freight cars. Background technique [0002] At present, the railway hopper car is one of the main means of transportation for transporting ore, grain and other goods. It mainly adopts the structure of loading and unloading from the top. Compared with the box car and the open car, it can effectively shorten the loading and unloading operation time, reduce the loading and unloading cost, and improve the loading and unloading conditions. In order to meet the needs of waterproof, rainproof and dust-proof for product transportation, a movable top is set at the loading port on the top of the car body. Most of these convertible tops are steel tops with fixed joints with the car body, which can be opened or closed by longitudinal translation or rotation along the rotation axis. The loading port of the hopper car carrying ore and other goods is ...

Problems solved by technology

However, these two commonly used implementations have the following disadvantages: in the first implementation, the pressure gas source of the cylinder will consume the train pipe pressure gas of the vehicle, which may lead to insufficient train pipe pressure gas, which will affect the braking effect of the train; The second implementation method, because the steel roof is too heavy, requires extremely high rigidity of the chain, and at the same time it is easy to cause damage to the chain, and it is difficult to operate the entire driving mechanism
