Description

The invention relates to urban electric transport, in particular to the intersection of the contact lines of a tram and trolleybus and is an improvement of the invention according to the author. Mg 1294661.

The aim of the invention is to improve the reliability of operation by increasing the electrical and mechanical strength.

FIG. 1 shows the intersection of the contact lines of a tram and trolleybus, general view; in fig. 2 is a section A-A in FIG. 1 (bumper not shown); in fig. 3 is a view B in FIG. one; in fig. 4 is a view of B in FIG. one.

The intersection device 1 of the tram and trolleyub contact lines contains power elements 2 in the form of insulating teeth parallel to each other, for example, of a rectangular cross section, to which metal running elements of tram 3 mounted in meeting centers and intermediate 4 mounted between said centers Meetings in the middle part of the intersection 1. At the end sections of intersection 1 in the direction of the tram, arc arresting devices 5 with running elements 6 are mounted. The meeting centers consist of 7, mounted on the insulation bars x 2, and turning

bases 8, on which the running tires 9 with flanges and end clamps 10 are fixed for fastening the contact wires of the trolleybus line.

The running tires 9 are arc-shaped with a horizontal section at the intersection. The bases 7 and 8 are hingedly connected to each other by means of axles 11. To the pivoting bases, limiters 12 of rotation angles and lugs 13 are attached for suspending the intersection. The continuity of the electrical circuit is carried out through an insulated electrical jumper 14, the ends of which are mounted on the brackets 15 using clamps 16.

To ensure that the contact wires of the tram are not broken, reduce their wear, and increase the stability of the tram current collector during the passage of resettlement 1, the runner 17 and 18, each of which is a cTJapwyio structure and includes a guide 19 made of a round bar and ribs 20 welded to its ends for fastening the runner EV 17 and 18 at one end on the contact wire, and the other - on the bracket 15 by means of clamps 16.

Vibration dampers 21 are attached to the end clamps 10 to reduce wear and prevent breaking the contact wire of the trolleybus line, made in the form of a lever with a clip for fastening to the contact wire. Replaceable tram running elements are made in the form of segments 22 and fixed to the flanges of the running tires 9 through insulators 23 by means of bolts 24

The working surfaces of replaceable running elements are cylindrical with a radius of 25-30 mm. Such an implementation allows the use of 30-150 ° interchangeable elements of equal height in the entire range of meeting angles 30-150 °, which ensures a smooth, unstressed passage of the tram pantograph through the centers of the encounters and two (opposing) directions.

At the intersection 1, anti-shock bars 25 are mounted, ensuring the prevention of the possibility of damage to the intersection by 1 trolleybus rods during their emergency derailment from contact wires. Anti-shock bars 25 are installed at the entrance sections of the intersection along the course of the trolleybus movement, with one person fixed on the swivel bases with the help of brackets 26 and 27, and others on the contact wire of the tram with the help of clamps 28. The shock bar 25 is selected depending on the angle of contact of the tram and trolleybus overhead wires. The impact bar is made of an insulating material, for example, DSP-B-E wood laminate according to GOST.

The device works as follows.

The pivoting bases 8 are connected to the trolleybus line contact wires by means of clamps 10, whereby the pivoting bases 8 are self-aligning along these wires. When the trolley bus is moving, the head of the current collector smoothly and smoothly passes from the contact wire through the vibration damper 21 to the running bus 9.

With acute angles of 30–60 and 120–180 ° meeting contact lines when a tram moves in any of the opposite directions, its current collector uninterruptedly passes the meeting centers alternately, resting on different points of the working surfaces of segments 22, without touching the trolleybus contact line. At meeting angles of 60-120 °, a gap is formed in the running line of the current collector of a tram in the center of the meeting and the current collector of the tram traverses this section by springboard, breaking it through the air.
