Technical field
It the utility model is related to a kind of three-chip type sidewall structure on subway run-through channel.
Background technology
Subway run-through channel generally comprises vestibule diaphragm assembly, pedal assembly, top plate assembly, framed side wallboard assembly；Wherein side wall assembly
Typically use two-piece type side wall metal or the nonmetallic side wall of integral type；The compression of two-piece type side wall metal is limited, and what is had can't prevent
Only sidewinder the distortion brought and influence the side wall life-span.The nonmetallic side wall of integral type can meet compared with multi-state, but its dependence is
Self-deformation so requires higher, nonmetallic side wall fatigue service life is typically on 10 years left sides come what is realized to nonmetallic side wall
It is right.
The content of the invention
Purpose of utility model is to provide a kind of three-chip type side wall, mainly for solving track transportation industry run-through channel two panels
Formula side wall decrement is small, it is difficult to the problem of meeting small curve deformation.
In order to achieve the above object, the technical solution of the utility model is：A kind of subway three-chip type side wall, including medial side
Wall, left side wall, right-side wall and at least two groups quadric chains being made up of four connecting rods and an intermediate bar, four connecting rods
Both ends be hinged, and the both ends of intermediate bar are hinged on two relative connecting rods, are fixedly connected with the middle side wall
Mounting seat, mounting seat are provided with middle bearing pin, and the middle bearing pin is arranged on the middle part of intermediate bar, the left side wall and right-side wall
On be respectively equipped with left shaft holder and right axle bearing, oscillating bearing, four connecting rods are equipped with left shaft holder and right axle bearing
Adjacent two rod hinge connections at be equipped with joint bearing pin, two joint bearing pins are separately mounted to left shaft holder and right axle bearing
On two oscillating bearings.
Two groups of quadric chains are separately mounted to the upper and lower part of middle side wall, left side wall and right-side wall.
The left side wall and the outer upper of right-side wall and bottom are respectively provided with connecting seat.
Dovetail groove is equipped with the left shaft holder and right axle bearing, the end of joint bearing pin is located in dovetail groove.
After said structure, the utility model mainly includes middle side wall, left side wall, right-side wall and quadric chain,
Quadric chain can make left side wall, right-side wall and middle framed side wallboard relative motion, increase framed side wallboard integrally stretching reduction length,
Meet the requirement of small curve deformation, wherein quadric chain can make left side wall and right-side wall in motion definitely in.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 rear perspective view；
Fig. 3 is Fig. 1 A-A sectional views.
Embodiment
The utility model is described in further detail below in conjunction with the embodiment that accompanying drawing provides.
Referring to shown in Fig. 1,2,3, a kind of subway three-chip type side wall, including middle side wall 1, left side wall 2, right-side wall 3 and two
The quadric chain 20 that group is made up of four connecting rods 4 and an intermediate bar 5, the both ends of four connecting rods 4 are hinged, and in
Between the both ends of bar 5 be hinged on two relative connecting rods 4, mounting seat 6 is fixedly connected with the middle side wall 1, in mounting seat 6
Provided with middle bearing pin 7, the middle bearing pin 7 is arranged on the middle part of intermediate bar 5, is respectively equipped with the left side wall 2 and right-side wall 3
Oscillating bearing 10, the phase of four connecting rods 4 are equipped with left shaft holder 8 and right axle bearing 9, left shaft holder 8 and right axle bearing 9
Adjacent two hinged places of connecting rod 4 are equipped with joint bearing pin 11, and two joint bearing pins 11 are separately mounted to left shaft holder 8 and right axle bearing
On 9 two oscillating bearings 10.
It is shown in Figure 2, in order to ensure that left side wall 2 and right-side wall 3 can be absolutely in expansion and contraction process middle and upper part and bottom
To centering, ensure the synchronization of deformation, two groups of quadric chains 20 are separately mounted to middle side wall 1, left side wall 2 and right-side wall
3 upper and lower part.
It is shown in Figure 2, it is connected for convenience with the run-through channel of subway, the outer upper of the left side wall 2 and right-side wall 3
Connecting seat 12 is respectively provided with bottom.
It is shown in Figure 3, dovetail groove 13, the end of joint bearing pin 11 are equipped with the left shaft holder 8 and right axle bearing 9
In dovetail groove 13.Dovetail groove 13 has position limiting structure, can prevent left side wall 2 and right-side wall 3 from will be closed in displacement process
The protection structure that section bearing pin 11 fractures.
Referring to shown in Fig. 1,2,3, left side wall 2 and the connecting seat of right-side wall 3 12 are connected with the run-through channel of adjacent subway, four
