Drawing type observation device of railway hopper car and railway hopper car

Abstract

An end wall plate of the railroad hopper car comprises an end wall vertical face and an end wall inclined face, an observation hole is formed in the end wall inclined face, the sliding cover is arranged on the end wall inclined face of the railroad hopper car in a sliding mode and can seal the observation hole in the end wall inclined face, and a protective cover is arranged on the end wall inclined face of the railroad hopper car and can seal the observation hole in the end wall inclined face. The protective cover is arranged above the observation hole, a protective groove capable of containing the sliding cover is formed in the lower side of the protective cover, when the observation hole is sealed by the sliding cover, one end of the sliding cover is located in the protective groove, the driving mechanism is connected with the sliding cover, and the driving mechanism can drive the sliding cover to move. And the operation is simple, labor-saving, quick and time-saving, the manufacturing, the assembly, the disassembly, the maintenance and the inspection are convenient, and the requirements of high reliability and safety are met.

Description

technical field [0001] The invention belongs to the technical field of railway freight cars, and more specifically relates to a pull-out observation device for a railway funnel car and a railway funnel car. Background technique [0002] At present, my country's railway coal and stone ballast hopper cars all adopt a two-stage transmission bottom door opening and closing mechanism. The main existing railway hopper cars are located above the inclined surface inside the end wall in order to facilitate the staff to observe the remaining cargo in the car after unloading. An observation hole is set on the end plate of the middle part, on which there is an observation hole cover that can be flipped from the outside to the inside of the vehicle. Inside. Since the hopper car uses the hopper of the elevated silo or the loader to carry out the loading operation, the observation hole cover exposed on the cargo contact side without any protective measures, under the action of the continuou...

AI Technical Summary

Problems solved by technology

Since the hopper car uses the hopper of the elevated silo or the loader to carry out the loading operation, the observation hole cover exposed on the cargo contact side without any protective measures, under the action of the continuous impact force of the falling cargo from a high place, its main connecting parts are easily damaged. The goods were smashed, causing the observation hole cover to fall off the end wall of the funnel car, and the goods in the funnel car leaked out of the car through the observation hole.

In order to solve the problem that the observation hole cover falls off the end wall of the car body due to the impact of the cargo, the observation hole cover of the railway funnel car (see invention patent application number: 201810355424.8) (see Figure 29 ) Adopt the improved technical scheme of externally placing the hinge and the hinge seat, and set the hinge seat on the outside of the end wall of the improved observation hole cover of the railway hopper car. Although the risk of the cargo being smashed is overcome, there are still the following problems: a The observation hole cover is closed by its own weight, and it is heavy, so it is laborious to push it open by hand during observation. With the increase of the opening of the observation hole cover, the hinge seat is used as the fulcrum of rotation, according to the moment balance principle of the cover's own weight and hand thrust , the force required to push it by hand also increases correspondingly, so it feels more and more laborious to push the opening of the observation hole cover by hand. When the opening angle is too large, it is more laborious and less humane; When the cover is observed, the two rotating arms occupy the space outside the observation hole, and at the same time, the hands and arms occupy most of the space near the outside of the observation hole. When observing, the eyes cannot be close to the observation hole on the inclined end plate of the end wall. The problem that the field of vision of residual cargo is small and the observation line of sight is affected
