Abstract

The utility model relates to a reinforcement anti-bouncer of a switch point rail, which is suitable for switches for railways, subways and light railways and is particularly suitable for hook-type movable outer locking switches. The reinforcement anti-bouncer consists of a hook plate, rolling wheels and pin shafts and is characterized in that the hook plate (1) is connected with the rolling wheels(2) by the pin shafts (3), and the hook plate (1) is connected with the switch point rail (5) by a bolt (4), thereby forming the reinforcement anti-bouncer of the switch point rail; the hook plate (1) is arranged at the towing point by matching with an outer lock and can also be arranged between the towing points independently; the hook plate (1) is connected with the switch point rail (5); and the protruding part of the hook plate (1) and the rolling wheels (2) are arranged at the lower part of a stock rail (6).

Description

Point tongue reinforcement anti-bouncing device

(1) technical field:

A kind of point tongue reinforcement anti-bouncing device is applicable to the track switch of railway, subway, light rail.Be specially adapted to the outer locking track switch of hook-type transfer.

(2) background technology:

Existing railway switch moving part (as tongue, heart rail, movable wing rail) and being connected of conversion equipment be by erecting device rod member be connected iron and directly connect, the most advanced and sophisticated position of the present track switch of China (as tongue, heart rail, movable wing rail) is that slicing is shaped, point is thin and rigidity is low, front rod of a point has been cancelled at the tip of tongue when particularly adopting the outer locking of transfer, and the towing point of conversion equipment has longer distance apart from the tip, cause the tip that the slit is arranged easily, can bring potential safety hazard; The traction of conversion equipment by the transmission power of external lock jam plate, easily produces component upwards, make tongue in transfer process on escape hook and influence the normal conversion of track switch.Installing and using of point tongue reinforcement anti-bouncing device helps the safety of railway operation.

(3) summary of the invention:

The utility model point tongue reinforcement anti-bouncing device, technical problem to be solved is: a kind of point tongue reinforcement anti-bouncing device is provided, the rigidity at raising moving part tip guarantees that the tip is closely connected good, can prevent the upward fault generation of escape hook of moving part in the transfer process (as tongue) again.

The purpose of the utility model point tongue reinforcement anti-bouncing device can realize by following measure: a kind of point tongue reinforcement anti-bouncing device, form by hook plate, roller, bearing pin, connecting bolt.It is characterized in that: roller is connected by bearing pin with hook plate, and hook plate links together with bolt and point tongue again, constitutes point tongue reinforcement anti-bouncing device.With goat and erecting device thereof or comprise that outer locking matched with devices uses.

The utility model has following characteristics compared to existing technology:

1, point tongue reinforcement anti-bouncing device can improve the rigidity of the point of switch, helps eliminating most advanced and sophisticated slit, guarantees railway operation safety.

2, point tongue reinforcement anti-bouncing device can prevent to jump on the tongue, overcomes in the transfer process owing to the translation exception of jumping on the tongue, outer locking device breaks off relations and causes.

Fig. 2 is installed in the vertical view of tongue part for the utility model track switch reinforcement anti-bouncing device

(5) specific embodiment:

Below in conjunction with accompanying drawing the enforcement that the utility model point tongue reinforcement anti-bouncing device is installed on point tongue is provided specific embodiment, further describe: a kind of point tongue reinforcement anti-bouncing device, form by hook plate, roller, bearing pin, it is characterized in that: hook plate 1 connects as one by bolt 4 and point tongue 5, roller 2 connects as one by bearing pin 3 with hook plate 1, constitutes point tongue reinforcement anti-bouncing device.Hook plate 1 can be installed on tongue towing point place by supporting external lock, also can be arranged separately between towing point, hook plate 1 links together with point tongue 5, and the extension of hook plate 1 and roller 2 are installed in stock rail 6 bottoms, when jumping on the tongue 5, be rolling friction between hook plate 1 and the stock rail 6.

Claims (3)

1. point tongue reinforcement anti-bouncing device, constitute by hook plate, roller, bearing pin, it is characterized in that: hook plate (1) is connected by bearing pin (3) with roller (2), and hook plate (1) connects as one by bolt (4) and point tongue (5) again, constitutes point tongue reinforcement anti-bouncing device.

2. according to the described a kind of point tongue reinforcement anti-bouncing device of claim 1, it is characterized in that: the supporting external lock of hook plate (1) is installed on the towing point place and is arranged separately between towing point.

3. according to the described a kind of point tongue reinforcement anti-bouncing device of claim 1, it is characterized in that: hook plate (1) links together with point tongue (5), and the extension of hook plate (1) and roller (2) are installed in stock rail (6) bottom.
