Description
Technical field
The invention belongs to track train air-tight test guest room end seal fields, and in particular to one kind is used for gas
The train plug at end part device of tightness test.
Background technique
The high-speed track passenger cars such as EMU have more harsh required precision to the pressure control in its guest room compartment, because
This needs the positions such as the door to its compartment, window, air-conditioning interface to block respectively behind guest room compartment and bottom frame floor assembly,
So that the compartment inner cavity above floor is formed confined space, and is taken out the air in the confined space using vacuum pump class negative pressure system
From when the difference of both specified vacuum degrees of practical vacuum degree and vacuum pump in compartment inner cavity is less than theoretic pressure difference index
When, it can assert that the air-tightness of tested train passenger compartment meets acceptance criteria.
Positions regular shapes such as the window and air-conditioning interface in guest room compartment and area is smaller are matched with size and have rubber
Ideal sealing effect can be realized in the plate seal plate of sealing strip, but when guest room compartment 11 and bottom frame floor assembly,
The structure member assembly relation of compartment end is as shown in Figures 1 to 5, and the top of end chassis 14 is equipped with horizontal ground sheet tray 14-
1, the front end center of end chassis 14 is equipped with hitch docking facilities 13 outstanding, and hitch docking facilities 13 are located at ground sheet tray 14-1's
Lower section.The front end face in guest room compartment 11 and the front end of end chassis 14 dock and are connected with the rear end face of headwall 12 respectively.Vehicle
The center round tube 13-1 of 13 end of hook docking facilities passes through doorframe and from inside to outside with the exposed front end in headwall A of hanging posture
Outside face, the doorway structure at 12 middle part of headwall is divided into doorway upper area 12-1 and door by the horizontal plane where round tube axis
Mouth lower area 12-2.
In order to implement to block the doorframe corresponding region on headwall 12, as shown in fig. 6, existing solution is to make respectively
Make the upper plugging plate 15 with semicircle upper card slot 15-1 and the lower plugging plate 16 with semicircle lower bayonet slot 16-1, upper plugging plate
15 shapes are identical as the shape of doorway upper area 12-1, but the size of 15 outer contour of upper plugging plate is doorway upper area
The 120% of 12-1 profile linear dimension, lower 16 shape of plugging plate is identical as the shape of doorway lower area 12-2, but lower plugging plate 16
The size of outer contour is the 120% of doorway lower area 12-2 profile linear dimension.In semicircle under card slot 15-1 and semicircle
The diameter of card slot 16-1 is the 120% of center round tube 13-1 diameter, and the two is spliced to form a card slot circular hole simultaneously jointly
It covers on the outer diameter of center round tube 13-1.In use, the band card slot that both upper plugging plate 15 and lower plugging plate 16 are collectively formed
12 middle part doorway structural traps of headwall, the entirety plugging plate are used light plastic plate material, card slot by the whole sealing plate of circular hole
Gap between circular hole and center round tube 13-1 outer diameter is for making negative pressure exhaust pipeline and pressure gauge pipeline be able to insertion headwall
12 rear portion simultaneously reaches in guest room compartment 11.With rubber seal packing material by remaining gap around the round tube 13-1 outer diameter of center
After being blocked, then it is pasted onto outside the doorframe on headwall 12 with the integral plastics plugging plate that plastic cloth and adhesive tape complete this
Portion can carry out air-tight test.
However, the headwall 12 of different automobile types often corresponds to entirely different doorframe shape, size and area, equally, hitch
Docking facilities 13 also have different diameter dimension and its different size relative to the hanging exposed part in 12 outside of headwall.Cause
This, existing integral plastics plugging plate above-mentioned is also required to the doorway structure for different automobile types, and corresponding production structure snd size are equal
With a variety of plastics plugging plates of vehicle doorframe structure Corresponding matching to be measured, plastics plugging plate broad categories, versatility are thereby resulted in
The problem of difference, occupancy storage space.On the other hand, although integral plastics plugging plate lighter in weight, convenient for fix, its structure compared with
For fragility, it is easy to cause its air-tightness to decline because colliding with or aging due to cracks.In addition, to card slot circular hole and center round tube
The process that gap between 13-1 outer diameter is filled and seals is not only time-consuming and laborious, inefficiency, and is easy in negative pressure test
Middle there is a phenomenon where fillers to loosen gas leakage, and makes and cause to damage to negative pressure exhaust pipeline and pressure gauge pipeline.
Summary of the invention
It is by upper and lower two pieces semicircle cards to solve headwall doorframe plugging plate used by existing train air-tight test
The integral plastics plugging plate with card slot circular hole that the plugging plate of slot is put together jointly, to outside its card slot circular hole and center round tube
The process that gap between diameter is filled and seals takes laborious, inefficiency when not only, and is easy to happen filler and loosens leakage
The phenomenon that gas；And existing plastic plate structure is more fragile, is easy to cause under air-tightness because colliding with or aging due to generates crack
Drop；And existing integral plastics plugging plate needs the doorway structure for different automobile types and makes profile-followed size and structure and become
