Description

The invention relates to stationary devices for protecting switch elements from damage by the wheels of a train that has come off the rails (trolleys, locomotives) and can be used mainly in the mining industry.

A safety device for switch elements is known, containing bars adjacent to the rail cheek, tapering in terms of the direction of movement of the vehicle, the upper plane of which is made at the level of the working surface of the rail head with section 1 inclined from the direction of movement of the vehicle.

A disadvantage of the known device is that it protects individual elements of the switch not in all directions of the vanishing wheels from breakages.

The purpose of the invention is to increase the reliability of protection from the field of switch elements in any direction of movement.

This goal is achieved by the fact that, in a safety device for switch elements, containing bars adjacent to the rail neck, tapering in the direction of movement of the vehicle, the upper plane of which is made at the level of the working surface of the rail head with a section inclined from the direction of movement of the vehicle installed on each rail of the linear and curvilinear sections of the track in front of the sharks and the crossbar of the switch; moreover, the rail is covered by each bar with two the sides, and the bar is made with longitudinal guiding ribs of the upper plane and with a groove for the passage of the wheel flange, while the height of the longitudinal guide rib on the outside of the track is greater than the height of the wheel flange.

FIG. 1 shows the proposed device with possible variants of the vanishing of the wheels of the rolling stock, top view; FIG. 2 shows section A-A in FIG. one.

The device consists of bars 1, covering the rails 2 on the outside and the inside, with inclined sections 3 in the direction of rolling stock movement and horizontal upper planes 4,

made at the level of the head 5 of the rail 2. The bars 1 along the outer edges have longitudinal guide ribs 6 and 7 for displacing the wheels 8 to the head 5 of the rail 2. The horizontal upper plane 4 of the bar 1 on the inner side of the rail 2 is made with a longitudinal groove 9 for the flange wheels 8 and unstressed passage through the device of wheels 8 rolling stock not descended from rails 2. The height of the longitudinal guiding ribs 7 of the bars 1 on the outer side of the rails 2 and the depth of the grooves 9 on the inner side of the rails are greater than the flange of the wheel 8 of the rolling stock. For greater rigidity, the device has

transverse ribs 10. The device can be made with a base 11, covering the rail foot, and secured to it with wedges 52. The bars in the plan are made tapering in the direction of movement of the vehicle.

The device works as follows.

Wheels 8 wheelset rolling stock collides on sloping

5 section 3 of bar I. Climbing along inclined section 3, one of the wheels 8 of the wheelset of the car with its side surface comes into contact with the longitudinal guide edge 7 of the bar on the outside of the rail. Move up along

0 the longitudinal guide rib 7, which narrows towards the head 5 of the rail 2 of bar 1, the wheel 8 rises to the horizontal upper plane 4 and its flange gradually shifts to the longitudinal groove 9, occupying its operating position. A rigidly connected second wheel 8 of the wheel pair is moved along the inclined section 3 and the horizontal upper plane of the bar on the inner side of the other rail and at the same time is also set to operational reduction.

The proposed device is simple in construction and in manufacture, easy to install and reliable in operation, allows to increase the reliability of protection of all elements of the switch when the train is moving from any direction and when the rolling stock wheels are in any position.
