Abstract

The invention relates to a water filling nozzle access door of a railway vehicle, which is characterized by comprising a box type sealing frame, a fixed door plate and a sliding door plate, wherein the back surface of the box type sealing frame is a flat surface, and the front surface of the box type sealing frame is a cambered surface; the fixed door plate is fixedly connected with the box type sealing frame; nylon sliding ways are respectively installed on two side wings of an opening of the fixed door plate, and curve track grooves are formed in the nylon sliding ways; sliding shafts which are installed on the side surfaces of the sliding door plate are matched with the curve track grooves in the nylon sliding ways so as to open, close, install and fix the sliding door plate. The water filling nozzle access door is of an upper sliding type independent closed structure and can be opened and closed flexibly without restriction by external conditions such as wind, snow, high cold and freezing; in the condition that other part structures of the existing interface are not changed, the water filling requirement of CRH (China Railways High-speed) trains in high cold areas is satisfied, and the normal operation of the vehicle is guaranteed.

Description

Guideway vehicle filling pipe end inspection door

Technical field

The present invention relates to a kind of filling pipe end inspection door of EMU vehicle, especially relate to a kind of vehicle filling pipe end inspection door that adapts to high and cold low temperature and windy snow operating environment.

Background technology

Continuous expansion along with the railway speed increase scope, the region restriction becomes the another bottleneck of high ferro development, be accompanied by first the 300 kilometers velocity stages in the world high and cold motor train unit open operation, the operating environment whether inspection door of outside vehicle can adapt to high and cold low temperature and windy snow seems very important, whether the vehicle inspection door can normally use the drive ability that determines vehicle, if inspection door can not normally use, vehicle just can not water filling so, cause vehicle sanitary accomodation and electric water boiler just can not normally use, have a strong impact on riding quality and the performance of high ferro.

At present, the filling pipe end inspection door mainly is made up of door-plate, framework, and framework is to be fixed by bolts on the car body, and the slideway of framework both sides is hollow out designs, is provided with two jump rings at the top of slideway, and effect is to prevent from shaking when door-plate from cutting out.The bottom of framework is provided with two rubber backstops, and effect is door alleviation door-plate impulse force when door-plate glides along track when opening.The door-plate both sides respectively are provided with a slide-bar for four jiaos, and it is spacing with nut that slide-bar inserts hollow out formula slideway inner end, prevents that slide-bar from coming off from slideway.When opening door-plate, need push plate to the inside, the door-plate slide-bar backs down jump ring, slips over the slideway flex point, under the self gravitation effect, drops to naturally on the rubber backstop.Otherwise be the process of closing the door.This kind structure inspection door mounting process is poor, need be at car body processing mounting process square opening, this opening processing process complexity not only, and bring influence for inspection door cavity leak tightness, through the actual operation of reaching the standard grade, this mouth for mainly advance the snowfield because of.The structure of inspection door is the open type structure, itself does not possess the snow defence function, there are the slit in door-plate and car body opening junction, when this just caused vehicle to move under wind and snow weather, snow entered in the car body cavity and fills up whole cavity, and can't remove, cause door-plate inwardly to promote, slide-bar can't be crossed the slideway flex point, and door-plate can't be opened, thereby can't carry out the water filling operation.And since the snow-broth of the overflow water during water filling, thawing and condensed water can freeze at slideway, can cause when opening clamping stagnation or do not open, influence operator's water filling operation, the car internal sanitary accomodation can not use, electric water boiler is anhydrous, the passenger can not drink hot water, has a strong impact on train and normally moves, and reduces the travelling comfort of high ferro greatly.

Summary of the invention

The purpose of this invention is to provide and a kind ofly in high and cold low temperature and windy snow operating environment, can normally use, guarantee the vehicle filling pipe end inspection door of operation smoothly.

For achieving the above object, the invention provides a kind of guideway vehicle filling pipe end inspection door, it is characterized in that: comprise box sealing frame, fixedly door-plate, slide door plate, box sealing frame back is the plane, the front is cambered surface, fixedly door-plate is captiveed joint with box sealing frame, fixedly be separately installed with the nylon slideway on two of the door-plate opening part flanks, the curvilinear path groove is arranged on the nylon slideway, the slide door plate side is equipped with the curvilinear path groove fit on slide-bar and the nylon slideway, is used for slide door plate and realizes opening, closing and install and fix.

The present invention adopts gliding style independence enclosed construction, door opens and closes flexible movements, is not subjected to external condition such as wind and snow, high and cold, freezing restriction, guarantees under the constant situation of other position structures of existing interface, realize extremely frigid zones motor train unit waterflooding requirement, the assurance vehicle is normally runed.

Description of drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 analyses and observe closed condition figure along the A-A line among Fig. 1;

Fig. 3 analyses and observe open mode figure along the A-A line among Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2, the present invention includes box sealing frame 1, fixedly door-plate 2, slide door plate 3, box sealing frame is formed by stainless-steel sheet bending welding, the back is that the plane is connected with car body, the front is that cambered surface is used to install and fix door-plate, fixedly be separately installed with nylon slideway 4 on two of the door-plate opening part flanks, two curvilinear path grooves 6 are arranged on each nylon slideway, 7, slide door plate is formed by the stainless-steel sheet welding, 2 slide-bars 5 are respectively installed in two sides, two slide-bars of every side respectively with each self-corresponding nylon slideway on the curvilinear path groove fit, slide door plate is to slide to realize to open by slide-bar given curvilinear path groove on slideway, close and install and fix.Slideway curvilinear path groove has locking flex point function, when opening and closing, slide has directed limit function, guarantee when specifically being unlatching that door stops at opening and do not fall, assurance water filling operation is normally carried out, utilize the deadweight of slide door plate to reach self-locking state when closing, can not move inward at door-plate under the aerodynamic loading when guaranteeing vehicle operating, state keeps Locked.

This filling pipe end inspection door self structure is enclosed construction, in time discharges for guaranteeing water, at this inspection door the discharge overflow water-bound is set.

Claims

1. guideway vehicle filling pipe end inspection door, it is characterized in that: comprise box sealing frame, fixedly door-plate, slide door plate, box sealing frame back is the plane, the front is cambered surface, fixedly door-plate is captiveed joint with box sealing frame, fixedly is separately installed with the nylon slideway on two of the door-plate opening part flanks, and the curvilinear path groove is arranged on the nylon slideway, the slide door plate side is equipped with the curvilinear path groove fit on slide-bar and the nylon slideway, is used for slide door plate and realizes opening, closing and install and fix.
