Description
Technical Field
The utility model relates to a railway switch technical field, concretely relates to railway switch bolt anti loosening structure.
Background
The railway turnout is impacted by the train passing the turnout for a long time, and the bolt and the nut are loosened or fall off due to severe vibration in the using process, so that great workload is brought to line maintenance and repair, and the driving safety is seriously influenced. In order to solve the problem of looseness of bolts and nuts, the bolt and nut anti-loosening structure commonly applied in the domestic industry at present has the problems that a single-hole anti-loosening piece can only be inserted into a clamping groove from top to bottom, the clamping groove cannot be too high in position, the anti-loosening piece and the clamping groove are small in overlapping range, the anti-loosening piece is easy to deform and fall to cause anti-loosening failure, installation is seriously influenced, the single-hole anti-loosening mechanism can only be used for preventing looseness of a single bolt and nut, and the cost is high.
SUMMERY OF THE UTILITY MODEL
For solving the defect of the prior art, the utility model provides a railway switch bolt locking device easy to assemble, the reduce cost, locking effect is stable.
The technical scheme of the utility model is that: the utility model provides a railway switch bolt anti loosening structure, includes bottom plate and limiting plate be equipped with the bolt hole that two confession bolts passed on the bottom plate at least be equipped with the locking hole that matches with the quantity and the position of bolt hole on the limiting plate, the locking hole can block bolt hexagon head be equipped with the flange on the bottom plate be equipped with the flange hole that supplies the flange to pass on the limiting plate be equipped with the hasp spare that can prevent the limiting plate and drop on the flange.
Preferably, the flanges are arranged on both sides of the bottom plate and/or in the middle of the bottom plate.
Preferably, the flange is vertically disposed on the base plate.
Preferably, the bottom plate is provided with a folded edge, and the limiting plate is provided with a bent edge.
Preferably, the folded edge is arranged outside the bent edge,
preferably, the crimp is disposed outside the fold.
Preferably, the locking member is a cotter pin, and the flange is provided with a pin hole for the cotter pin to pass through.
The utility model has the advantages that: the bottom plate is at least provided with two bolt holes, and the limiting plate is provided with anti-loosening holes matched with the bolt holes in number and position, so that a plurality of bolts can be locked and loosened at the same time, the cost can be reduced, and the installation is rapid; the flange that will set up on the bottom plate passes the flange hole on the limiting plate, fixes bottom plate and limiting plate through the hasp piece to prevent that the locking piece from droing, easy to assemble, locking effect is stable.

FIG. 2 is a top view of the base plate;
fig. 3 is a plan view of the limiting plate.
Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The utility model discloses technical scheme as follows: the utility model provides a railway switch bolt anti loosening structure, including bottom plate 1 and limiting plate 2, as shown in fig. 2, be equipped with two bolt holes 3 that supply the bolt to pass on bottom plate 1 at least, as shown in fig. 3, be equipped with the locking hole 4 with the quantity and the position matching of bolt hole 3 on limiting plate 2, locking hole 4 is polygon plum blossom hole, can block bolt hexagon head and prevent rotating, it is shown according to fig. 1, be equipped with flange 5 on bottom plate 1, be equipped with flange hole 6 that supplies flange 5 to pass on limiting plate 2, be equipped with the hasp spare that can prevent limiting plate 2 to drop on flange 5.
The flanges 5 are arranged on two sides of the bottom plate 1, or in the middle of the bottom plate, or on two sides and the middle of the bottom plate, and the flanges 5 can be formed by flanging, or welded, or realized by punching and flanging; when the limiting plate is installed, in order to enable the flange to conveniently penetrate through the flange hole in the limiting plate, the flange is vertically arranged on the bottom plate along the direction of the limiting plate, and therefore the limiting plate is convenient to install.
In order to strengthen the strength of the bottom plate and prevent deformation, the bottom plate 1 is provided with a folded edge 7, and in order to prevent the limiting plate from deforming under stress after contacting with the nut, the limiting plate 2 is provided with a bent edge 8; according to fig. 1, where hem 7 is placed outside of hem 8, it is also possible to obtain that hem 8 may be placed outside of hem 7, according to the teachings described above.
In order to facilitate the installation of the limiting plate, the locking fastener is a cotter pin, and a pin hole for the cotter pin to pass through is arranged on the flange 5.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
