Abstract

Use: railway transport, installation of contact suspension electrified railways. SUMMARY OF THE INVENTION: The device comprises two parts of a raskatochno-installation train, the first of which includes a traction means and a raskatochny platform, and the other — a raskatochny platform and a motorcar. Each telescopic platform is equipped with a telescopic support and guides, on which the grippers are placed with the possibility of movement along the beam by means of a drive. Working mobile areas are located between the extreme main motor vehicle along the train and the additionally installed motor vehicle. 2 Il.

Description

The invention relates to railway transport, in particular to the field of the construction of a contact network of electrified railways, and is an improvement of the known device described in a.s. USSR № 1614969.

The known device for mounting the contact suspension of electrified railways includes two parts of a raskatochno-assembly train, the first of which contains a traction means, a raskatochny platform with drums for contact wires and a carrying cable and a column with clamps for them mounted for movement along rails and connected on one side through the cable block system with tension weights, and the second on the railcar, the unrolling platform with a column with movable grippers and guide blocks, telescopes Optical racks, drive winches of grips and mounted on columns made by telescopic, with the possibility of limited horizontal rotation of horizontal beams, in the upper part of each of which are placed guides with grippers connected by their other ends with driving winches, along the edges The telescopic column is hingedly mounted on one of the ends of each beam, on the retractable end of which there is a guide block.

A disadvantage of the known device is low productivity due to the implementation of installation work by several separate units.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that the device for mounting the contact suspension of electrified railways along a.s. No. 1614969, is provided with a mounting part including an additional railcar and platforms with elevating mounting platforms mounted in a link between the second MacfM railcar and an executive railcar 4, which can accommodate the assembly railways of the above railcars and platforms along the entire length of at least one role of the contact suspension.

FIG. 1 shows a general view of the device; FIG. 2 shows the structures of the spreading platform.

The device contains two parts of a wiring-installation train, the first of which contains a pulling means 1, a raskatochny platform 2 with drums 3,4 and 5 for contact wires 6,7 and a carrying cable 8, column 9 with grippers 10 for them installed movable along guides 11 and connected on one side through the cable-block system 12 with tension loads 13, and the other on railcar 14 and raskatochny platform 15 also with column 9 with movable grippers 10, and guide blocks 16.

Driving winches 17 of grippers 10 are mounted on guides 11. On columns 9, made telescopic, horizontal beams 18 are installed with limited rotation in a horizontal plane, in the upper part of each of which there are 11 grippers 10. Along the edges of guides 11 guide blocks 16, and at one of the ends of each beam a telescopic strut is hinged. 19, at the retractable end of which a guide block 20 is placed.

At least three (for covering one span) platforms 21 with elevating assembly platforms 22 are attached to the second part of the rakatochno-assembly train 22. An additional railcar 23 closes the train. The assembly platforms of railtracks 14 and 23 together with platforms 21 form scaffolding or scaffolding less than one span of the contact network (distance between adjacent supports, for example, 24 and 25).

The device works as follows.

After going to the train, the coupling of the assembly train stops so that the middle of the assembly site of the railcar 14 entering the second part,

located opposite the support 24 of the anchor section. The prepared ends of the rolling out wires 6 and 7 and the carrying cable 8, stretched through the entire train, fasten to the anchor support (not shown) from the rail car assembly site 23. The installation train disengages and the first part of it passes forward two spans, stops bearing 26, pulls out

0 wires 6 and 7 and supporting cable 8 on the rolled section. For this, all three winches 17 of the grippers are simultaneously engaged. 10, which travel along the guides 11 until failure back in relation to the direction of rolling. Meanwhile, the loads 13 are raised. At the rearmost point of the guides 11, the clamps 10 are closed, the clamps 6 and 7 and the carrying cable 8 are closed, and the winches 17 smoothly lower them.

0 Under the action of the force of weight of the load i3, the grippers 10 move forward, gradually tightening the wire 6 and 7 and the carrying cable 8. When the action of the weight of the load 13 is balanced by the tension force of the wires 6 and

5 7 and the carrying cable 8, the movement of the grippers 10, and accordingly the weights 13 stops. In such a state, the first part of the installation train holds up the tension of the wire and the carrying cable.

0 The second part of the installation train after tensioning the wires and the carrying cable from the railcar 14 installs the spring string 27 on the carrying cable 8, lays it in the console console saddle 25, installs a retainer (not shown), and takes the required zigzag of wires 6, 7 from all platforms together establishes supporting link strings (not shown) in the span;

0 wires in height. After completing the listed works for one span, it also stops at the middle of the assembly site of the railcar 14 naprochchv supports 26 and closes its grippers 10. These grips in the second

The 5 parts of the assembly train, located on the spreading platform 2, are rigidly fixed in the guides 11 and their closure corresponds to the interception of the tension of the wires 6, 7 and the carrying cable 8, which allows

0 of the first part of the train, relieve the tension of wires 6, 7 and carrier cable 8 by retraction of grippers 10 back with winches 17 and unfasten grips 10.

After that, the first part of the installation

5 trains can move to the next support. During the time of stationing, the second part of the installation train performs the same work as in the previous span. After the first part of the installation train again stretches the wires, the second part

the assembly train will release the wires and move one more flight forward.

Further, these cycles are repeated until the wire is terminated at the anchor section in such a way that parts of the installation train alternately move from the support to the support, while the distance between them varies from one to two spans.

After each such elementary cycle, the raskatochno-installation train leaves after itself the span of the contact network completely completed by assembly, and at the end of the work - a fully assembled anchor section, ready when the electricity is put into operation.

The anchoring of wires on the final support is performed from the second part of the installation train. The coupling of the wire of the finished drum with the wire of the new drum is on the unrolling platform 2.

When changing the direction of wire rolling it is necessary to perform maneuvers

and rearrange the device in reverse order.

According to calculations, the use of the device reduces the labor costs of installation

Anchor section of medium length (1.3 km) 2.5 times and increase the productivity of its work.
