SU10482A1 - A device for the acceleration of rail joint gaps - Google Patents

Description

In the proposed device, related to the type of known shock-free screw devices for the acceleration of rail butt clearances, the clips are made in the form of brackets, which engage the liners wedged between the rail base and its rail.

In FIG. 1 shows a side view of a device mounted on rails; FIG. 2 is a front view of it; FIG. 3-cross-section of the bracket and liner.

The device consists of two pairs of wedge-shaped liners A, having on themselves protrusions-shanks B and connected in pairs by hinges a on a spring device G, two brackets B with forked cheeks, in the lower part of which there are vertical grooves, and in the upper-cuts, and a Tightening screw with two nuts E, each fitted with two axles.

When operating the device, both pairs of inserts A, A turn on the hinges a, open, protrude under the rail base on both sides of the accelerated joint and after installing them between the head and the rail bottom where they enter freely, close, holding the spring G . Then clamping

brackets B are placed on top of the rail so that it comes between the cheeks of the brace, and the very cheeks with their grooves are located on the projections B of the liners (Fig. 2 and 3). A clamping screw D is attached to the clamping brackets, the nuts E of which, placed between the cheeks in their upper part, enter with their gutter pins into the notches in the cheeks. When the screw is rotated by a knob inserted into the hole 3 in the center of the thickening screw, the upper parts of the clips will approach or move apart and the brackets, acting on the protrusion B of the inserts, will turn the inserts A around their horizontal axis until THAT moment they jam mc between the HEAD and the rail foot; in this way, the clamping brackets will be fixed on the rail motionless and, with further rotation of the screw, will move the rail released to move. Upon termination of the rail movement and after loosening the clamping screw, all parts of the device are disassembled and removed.

When removing the device for passing a train, the liners may remain in place without obstructing its passage.

The subject of the patent.

A device for the acceleration of rail joint gaps, using two clamps that are wedged on the heads of the track rails, which are connected to each other by means of a screw, which is characterized by the fact that

Each Hs of the clamps is made in the form of brackets B with forked cheeks covering the shanks of the wedge-shaped liners A, acting as clamps wedged under the action of the screw D between the rail bottom and the bottom surface of its head.
