Abstract
The utility model relates to a fastening base plate for a point, which is used for fixing rail strips on the railway sleepers. The both sides of the shim plate 1 are symmetrically provided with a trapezoidal blocking shoulder 2 used for spacing, and the trapezoidal blocking shoulder 2 which forms a right angle with the shim plate face leans against one side of a screw spike hole 3. The upper part of the shim plate at the inner side of the blocking shoulder also is symmetrically provided with two stepped holes 4. The screw bolts 5 pass through the stepped holes 4, and the lower ends of the screw bolts are welded with the holes. The utility model has the advantages of good integrity for fixing the railway rail bar, high intensity and strong anti-pulling force, and the roots of the screw bolts and the shim plate adopt welding fixation to cause the utility model to have large locking force.
Description
The utility model relate to a kind of on railroad sleeper the fixing track switch elastic bar fastener backing plate of rail bar.
The buckle separated rail fastening backing plate that uses on the railway is to adopt the steel plate cutting processing to form at present, and fixing respectively in the rail both sides, and its shortcoming is as follows: 1, adopt the buckle press of pinch plate rail fastening poor.2, after bolt is lifted one's head from the backing plate bottom on the backing plate, withstand sleeper, be difficult for buckling piece is compressed, Chinese patent " elasticity separated rail fastening movable screw keyhole base plate " (notification number: 2076128), be characterized in: base plate has three screw thread channel fourth holes, a shoulder block and the perpendicular bolt hole of activity, and on symmetry direction, be provided with two limiting blocks.
The purpose of this utility model is: a kind of track switch elastic bar fastener backing plate with continuous plate overall fixed track is provided.
The realization the technical solution of the utility model is as follows: be provided with one in the bilateral symmetry of backing plate 1 and be used for spacing trapezoidal shoulder block 2, and be arranged with two screw spike holes 3 on the backing plate of shoulder block 2 both sides separately, and the one side that trapezoidal shoulder block 2 relies on screw spike hole 3 meets at right angles with the backing plate face, on the backing plate of shoulder block inboard, also be arranged with two stepped holes 4, bolt 5 passes this stepped hole 4, and its lower end and this eyelet welding connect.
The utility model has the advantages that: adopt the good integrity of continuous plate fixed rail rail bar, intensity height, bolt root and backing plate adopt welding fixedly to make its coupling mechanism force big, and uplift resistance is strong.Thus, the stability of track switch obviously improves, and can significantly reduce the maintainer amount of doing of track switch and the replacing number of times of sleeper thereof.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is a vertical view of the present utility model,
Fig. 3 is the schematic diagram of the W shape spring that is used with the utility model.
As Fig. 1, shown in Figure 2, the utility model comprises rectangle backing plate 1, bilateral symmetry at backing plate 1 is provided with trapezoidal shoulder block 2, be arranged with railway spike hole 3 on the backing plate of shoulder block both sides separately, and trapezoidal shoulder block meets at right angles with the backing plate face by the one side in screw spike hole 3, and also be arranged with stepped hole 4 on the backing plate of shoulder block inboard, can adopt integral cast with upper padding plate and last structure thereof, once-forming, bolt 5 passes the stepped hole 4 of backing plate, and the root shoulder of bolt 5 and backing plate stepped hole adopt welding fixing, when using the utility model, can with four screw spikes backing plate 1 be fixed on the sleeper earlier, by bolt 5 and top nut thereof rail bar tightly be stuck in down with W type spring (see figure 3).
