Abstract

The utility model relates to an inspection door for a water filling nozzle of a railway vehicle. The inspector door is characterized by comprising a box type sealing frame, a fixed door plate and a sliding door plate, wherein the back face of the box type sealing frame is a plane and the front face of the box type sealing frame is a cambered surface; the fixed door plate is fixedly connected with the box type sealing frame; two side wings at an opening of the fixed door plate are respectively provided with nylon sliding ways; each nylon sliding way is provided with a curve trace groove; the side face of the sliding door plate is provided with a sliding shaft which is matched with the curve trace groove on the nylon sliding way and used for opening and closing the sliding door plate and installation and fixation of the sliding door plate. With an upper sliding type independent sealing structure, the door is flexibly opened and closed without being limited by external conditions such as wind and snow, high and cold, and freezing, thus ensuring water filling requirement of motor train units at high and cold regions and ensuring normal operation of the vehicle under the condition that the structures of other parts of an existing interface are not changed.

Description

Guideway vehicle filling pipe end inspection door

Technical field

The utility model relates to a kind of filling pipe end inspection door of EMU vehicle, especially relates 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, regional limits 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 is mainly by door-plate, system framework, and framework is to be fixed by bolts on 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.Four jiaos of door-plate both sides respectively are provided with a slide-bar, and it is spacing with nut that slide-bar inserts hollow type 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, naturally drops on rubber backstop.Otherwise be the process of closing the door.This kind structure inspection door mounting process is poor, need to process the mounting process square opening on car body, and not only this opening processing process is complicated, and brings impact 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 gap 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 the overflow water during due to water filling, snow-broth and the condensed water of thawing can freeze on slideway, can cause when opening clamping stagnation or not open, affect 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 greatly reduces the travelling comfort of high ferro.

The utility model content

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

For achieving the above object, the utility model 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 nylon slideway, is used for slide door plate and realizes opening, closes and install fixing.

The utility model adopts upper 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 in the constant situation of other portion 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 utility model;

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

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

The specific embodiment

with reference to Fig. 1, Fig. 2, the utility model comprises box sealing frame 1, fixedly door-plate 2, slide door plate 3, box sealing frame is formed by the stainless-steel sheet bending assembling welding, the back is that the plane is connected with car body, the front is that cambered surface is used to install fixedly 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 fixing.Slideway curvilinear path groove has locking flex point function, when opening and closing, slide has directed limit function, guarantee when specifically opening 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 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, and the discharge overflow water-bound is set on this inspection door.

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 nylon slideway, is used for slide door plate and realizes opening, closes and install fixing.
