Abstract
The utility model provides a connecting and sealing structure of an air pipeline and a vehicle body of a railway vehicle. A corresponding position for mounting a braking pipeline on a vehicle body is provided with a through hole and the through hole is internally welded and fixedly provided with a sleeve; the inner diameter of the sleeve is slightly more than the outer diameter of the air pipeline; the air pipeline passes through the sleeve and a pipe connector is sleeved outside the air pipeline; one end of the pipe connector is connected with the sleeve; and the other end of the pipe connector is tightly clamped on the braking pipeline. When the connecting and sealing structure is mounted, the pipe connector passes through the air pipeline and the air pipeline passes through the welded sleeve; and the pipe connector is tightly screwed. When the connecting and sealing structure is detached, the pipe connector is loosened so that the air pipeline can be detached. The connecting and sealing structure has the advantages of convenience for operation and maintenance, good sealing performance and strong artistic performance.
Description
Technical field
The utility model relates to a kind of guideway vehicle airline and is connected hermetically-sealed construction with car body, belongs to guideway vehicle airline field engineering field.
Background technology
China's subway technology high-speed development, technology has reached international most advanced level, and the pipeline of Pneumatic brake systems generally need pass car body underframe and roof when pantograph (have pneumatic), therefore need on car body underframe and roof, punch.For car body, the seal operation after the punching is very important, if seal badly, the waterproof of car body and fire resistance will be affected.In the project, the method that is coated with sealant was adopted in the sealing in this place in the past.It is inconvenient to be coated with the technological operation of sealant method, and aesthetic property is not strong, and safeguards inconvenience, and pipeline can't be dismantled.
Summary of the invention
The utility model technical matters to be solved is, overcomes the above-mentioned shortcoming of prior art, provides a kind of guideway vehicle airline to be connected hermetically-sealed construction with car body, possess install simple, good airproof performance, advantage such as airline is quick detachable.
In order to solve above technical matters, the guideway vehicle airline that the utility model provides is connected hermetically-sealed construction with car body, it is characterized in that: the correspondence position that brake piping is installed on the car body offers through hole; Be welded with sleeve pipe in the said through hole; Said casing inner diameter is slightly larger than the external diameter of airline, and said airline passes in sleeve pipe, and airline is set with adaptor union outward; One end of said adaptor union is connected with sleeve pipe, and the other end of adaptor union is clamped on the brake piping.
During installation, adaptor union is passed airline, then airline is passed the sleeve pipe of car body welding, adaptor union is tightened got final product.During dismounting adaptor union is unscrewed, just can airline be disassembled.Originally the structure that is tightly connected is convenient operating maintenance not only, and good airproof performance, and aesthetic property is strong.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is that the utility model guideway vehicle airline is connected sealed structural representation with car body.
The specific embodiment
The guideway vehicle airline of present embodiment is connected hermetically-sealed construction with car body, and is as shown in Figure 1, and the correspondence position that brake piping is installed on the car body 4 offers through hole; Be welded with sleeve pipe 1 in the through hole; Sleeve pipe 1 internal diameter is slightly larger than the external diameter of airline 2, and airline 2 passes in sleeve pipe 1, the airline 2 outer adaptor unions 3 that are set with; One end of adaptor union 3 is connected with sleeve pipe 1, and the other end of adaptor union 3 is clamped on the brake piping 2.Wherein, adaptor union 3 is the reducing coupling joint.
Add man-hour at car body underframe or roof,, weld a welded tube bigger slightly then than airline diameter in the place punching that needs are installed airline.When carrying out the airline installation procedure, the reducing coupling joint is passed airline, then airline is passed the sleeve pipe of car body welding, adaptor union is tightened.When having problem to dismantle, adaptor union is unscrewed, can airline be pulled down like airline.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. a guideway vehicle airline is connected hermetically-sealed construction with car body; It is characterized in that: the correspondence position that brake piping is installed on the car body offers through hole, is welded with sleeve pipe in the said through hole, and said casing inner diameter is slightly larger than the external diameter of airline; Said airline passes in sleeve pipe; Airline is set with adaptor union outward, and an end of said adaptor union is connected with sleeve pipe, and the other end of adaptor union is clamped on the brake piping.
