Description
Technical field
The present invention relates to a kind of railcar sealing structure and its encapsulating method, particularly a kind of railcar draws reaches the standard grade
The sealing structure and encapsulating method in hole.
Background technology
With the continuous improvement developed rapidly with passenger to vehicle riding comfort requirement of railway technology, the sealing property of vehicle
An important technical indicator for weighing railcar quality is turned into.
The Seal Design for drawing string holes is not only required to sealing grade, need to such as consider waterproof and dustproof effect, but also
The anti-pyrotechnics performance and material of material sound insulation and noise reduction effect in itself need to be considered.
At present, the sealing structure for drawing string holes of existing railcar, as shown in figure 3, mainly including fixture block, drawing wire clamp
Block installs bushing 8（As shown in Figure 2）, sealing rubber pad 9, fluid sealant 10, bushing install fastener 81.
Fixture block is main to be made up of multipath module 6, wedge shape tight block 4, dividing plate 5 and the major part of lubricating oil four.
Wherein, the energy sealed diameter of multipath module 6 is the cable or pipeline of 3mm ~ 99mm.
Wedge-shaped tight block 4 is used in rectangular opening, can be compressed without built-in hold-down gear, during installation and hermetically-sealed cable, pipeline, mould
Tool and dividing plate.
Dividing plate 5 is arranged between each row's module for drawing fixture block installation bushing 8 of reaching the standard grade, for preventing cable and spool from being pulled out
Go out.
Lubricating oil is natural animal fat, and for lubrication and seal module, the tight block 4 of wedge shape installs bushing 8, energy with fixture block of reaching the standard grade is drawn
Ensure correct compression and sealing.
Multipath building block technique, only need to peel off sandwich layer, and individual module just can be made to seal the cable or pipeline of different-diameter.If no
Central plug is removed, then can be that change, the maintenance in later stage are got ready using module as acknowledgment copy.
The existing fixture block installation bushing of reaching the standard grade that draws mainly takes following two mounting means：
First, the pre-buried riveting nut in bushing installation floor face of vehicle body bottom frame 1, fastener 81 is installed with bushing（Be such as riveting nut,
Bolt, rivet etc.）Fixture block installation bushing of reaching the standard grade will be drawn with spring shim to be arranged on vehicle body bottom frame.
2nd, live distribution on vehicle body bottom frame 1, by the way of rivet installation.
Influenceed by car body strength, machine tool and module appearance and size, the perforate that car body draws string holes is usually round
Hole or slotted hole, therefore when using the sealing structure of above-mentioned prior art, with following deficiency：
1. vehicle body bottom frame need to now match somebody with somebody bushing mounting holes, and car body draws the bore size of string holes, generally very big, generally
It is 90 × 300mm.
2. need to first install and draw fixture block installation bushing of reaching the standard grade, then carry out the assembling of wire body, fixture block of reaching the standard grade is drawn so as to increased
Design, buying, the production cycle of bushing are installed.
3. in addition, in addition to drawing fixture block of reaching the standard grade and installing bushing installation, in addition it is also necessary to install sealing rubber pad, gluing sealing etc.
Complicated operating process, site operation is complicated, and the production cycle is long.
4. sealing rubber pad, fluid sealant, riveting nut, bolt, spring shim, rivet in the prior art, being used etc. zero
Part, increased related components cost.
5. the use of sealing rubber pad, so as to reduce the service life of sealing structure, increased maintenance difficulties.
The content of the invention
The technical problem to be solved in the present invention is directed to above-mentioned the deficiencies in the prior art, and provides a kind of railcar and draw
The sealing structure of string holes, parts needed for the railcar draws the sealing structure of string holes are few, low cost；It is not required to draw fixture block of reaching the standard grade
