EA015642B1 - Device for cable laying in a tunnel - Google Patents

Abstract

The invention is directed to improve operation quality by minimizing manual labor, and, accordingly, shortening time of forming a cable collector. Said technical result is characterized in that a device for cable laying in a tunnel comprises a railway mounted on a base with a power transport unit with a platform for a cable drum and a platform with a roller mechanism for cable guiding and laying. The device provides for two alternatives: the first – the platform for the cable drum has a rigid base for positioning the drum axis; the second – the platform is provided with rollers for the drum positioning by an outer rim. For both alternatives the mechanism of cable laying is embodied profiled as a frame with seats for an axis adapted to its longitudinal (left-right), transversal and vertical displacement in the frame seats.

Description

The present invention relates to the field of construction, and more specifically to the construction of underground tunnel cable manifolds.

The prior art identified a number of analogues of the proposed technical solution.

Known mobile cable layer mounted on a truck chassis, including remote outriggers and mounted on a support cable drum with lifting and lowering mechanisms, the support of the cable drum is made in the form of a stand made of two cantilevered central and side support racks with the formation of a rigid spatial structure (patent PM No. 15053, published on September 10, 2000, Bull. No. 25).

A hinged device for trenchless laying in the soil of cable sensing elements is known, comprising a supporting frame hung on a towing device of a towing device, narrow vertical knives with cassettes for feeding cables into the ground, cable drums, hydraulically controlled knife frames equipped with support rollers, narrow vertical knives with cassettes for feeding cables into the ground and cable reels.

Known devices are complex in design, the operation of laying the cable with their help is very time-consuming and expensive. In addition, the known construction of cable layers, for example according to patent PM No. 15053, cannot be used at all when laying cables in tunnels.

Currently, the issue of laying cables in underground collectors is relevant.

The collectors are underground tunnels of rectangular or round shape, designed for laying various underground utilities in them. They are built under street covers in an open way. On busy highways and squares of the city, collectors are constructed at great depths (up to 15 m) using the shield penetration method.

For laying communication cables, the collectors are equipped with special fasteners. For input into the collector of cable communication facilities, special introductory chambers are arranged.

The laying of cables in the collectors is carried out almost manually with the involvement of insignificant means of mechanization.

A device for a cable manifold in a tunnel is known, comprising a rail track and a platform with a cable drum disposed thereon. The known device provides cable laying in the tunnel of the collector, but does not exclude heavy manual labor. Cable laying is very time-consuming (see Guidelines for the construction of linear structures of local communication networks, part 1, clause 4.7. Laying of communication cables in collectors, tunnels and on bridges, clause 4.7.5. Laying of cables in tunnels, see the website yyr: //tGsshb.gi/Look 10 / 114_7? 01/09/2009).

The technical task of the proposed device is to improve performance by minimizing manual labor and, accordingly, reducing the time of formation of the cable collector.

The technical result is achieved by the fact that the device for laying the cable in the tunnel contains a rail mounted in the tunnel on a concrete base and multi-tier brackets mounted on the side walls of the tunnel for installing cable, a power transport unit, a platform for installing a cable reel, a platform are sequentially movably mounted on the rail with roller mechanisms for directing and laying the cable, while the mechanism for laying the cable is made in the form of a frame with sockets for an axis with a profile roller p d cable mounted with possibility of its longitudinal (left-right), lateral and vertical movement in the sockets of the frame.

The inventive device offers two options for installing a cable drum:

1) the platform for installing a cable drum is made with a rigid base for positioning the axis of the drum;

2) the platform for installing a cable drum is equipped with rollers for positioning the drum on the outer rim.

The invention is illustrated by drawings, where in FIG. 1. presents a General view of the device with a rigid positioning of the cable drum (option 1);

in FIG. 2 is a top view of the device according to option 1;

in FIG. 3 - section aa of the device according to option 1;

in FIG. 4 is a General view of the device with the positioning of the cable drum on the outer rim;

in FIG. 5 is a top view of the device according to option 2;

in FIG. 6 - section BB of the device according to option 2;

in FIG. 7 - cable management mechanism for the first and second options.

A device for laying a cable in a tunnel comprises a rail track 2 mounted in a tunnel on a concrete base 2. A power train 3 is installed on the track 2, a platform 4 for installing a cable reel 5 with cable 6, a platform 7 with roller guiding mechanisms 8 and laying mechanisms 9 cable 6. The laying mechanism 9 of cable 6 is made in the form of a frame 10 fixed on the platform 4 with sockets, in which the axis 11 with the profile roller is mounted with the possibility of longitudinal, transverse and vertical movement 12 m for laying cable 6 fixed to the walls (sides) of arms 13 of the tunnel.

The proposed device for laying cable provides for two options for installing cable reel 5:

1) the platform 4 for installing the cable drum 5 is made with a rigid base for positioning the axis of the drum (see Fig. 1-3);

2) the platform 4 for installing the cable drum 5 is equipped with rollers 14 for positioning the drum along the outer rim (see Fig. 4-6).

The proposed technical solution for positioning the cable drum on the outer rim can significantly reduce the dimensions of the platform 4 for installing the drum 5, which is important when working in tunnels of small diameter.

The laying mechanism 9 of cable 6 for the first and second options is the same.

The proposed design operates as follows.

A concrete base 1 is formed in the cable tunnel, on which the track 2 is rigidly mounted. A transport power unit 3 is mounted on the track, which pulls the platform 4 with the cable reel 5. With the platform 4 at a distance that provides the specified cable direction 6, the platform 7 is engaged. During movement, the drum 5 is rotated, the cable 6 from the drum 5 is unwound and gets on the roller mechanism of direction 8, then on the profile roller 12 of the laying mechanism 9 and then laid on and one of the specified brackets 13. After laying the cable and securing it on one of the brackets 13 along the entire length of the tunnel, the axis 11 of the stacking mechanism 9 is moved to the next socket of the frame 10 and the next laying is carried out, and so on until the cable is completely laid.

The proposed technical solution allows to practically eliminate manual labor and significantly reduce the time of formation of the collector.

Thus, the proposed technical solution allows for the installation of cables in the tunnel mechanically, almost completely eliminating manual labor and, accordingly, reducing the cost and duration of work.
