Description

Cable towing device for tunnel construction

Technical Field

The utility model belongs to the technical field of the construction auxiliary device, concretely relates to cable towing device for tunnel construction.

Background

The tunnel construction mainly depends on a heading machine for operation, a power supply cable of the heading machine needs to be led in from the outside of the tunnel, and the cable also needs to be synchronously followed when the heading machine tunnels inwards. Along with the continuous increase of tunnel tunnelling degree of depth, the management degree of difficulty of cable also grow gradually, if manage not good, often can appear the cable and receive the extrusion and drag the ground phenomenon for cable wearing and tearing lead to the cable to damage easily, not only influence the construction progress, also have the potential safety hazard simultaneously. In addition, after the tunnel is run through, the recovery difficulty is also higher due to the staggered joints of the cable coils.

SUMMERY OF THE UTILITY MODEL

The utility model provides a cable towing device for tunnel construction, the difficult problem of cable follow-up and recovery in the current tunnel construction of aim at.

Therefore, the utility model adopts the following technical scheme:

a cable towing device for tunnel construction comprises upright posts arranged at intervals along one side of a tunnel, wherein steel wire ropes are connected between the upright posts, and a plurality of towing cable assemblies are movably connected to the steel wire ropes;

the towing cable assembly comprises a pulley hung on a steel wire rope, two sides of the pulley are respectively connected with a horizontally arranged cantilever, and the front end of the cantilever is U-shaped; a V-shaped connecting rod is hooked between the two cantilevers, a guide groove for bearing a cable is formed in the lower end of the connecting rod, and a gap for the cable to pass through is reserved between the guide groove and the connecting rod; the guide way is the elbow form, and the both sides of guide way are articulated mutually with the connecting rod, and are equipped with the mounting plate that is used for compressing tightly the cable at the both ends of guide way.

Furthermore, the fastening piece is C-shaped, connecting lugs are arranged on the fastening piece and the guide groove, and the fastening piece and the guide groove are connected through a screw.

Further, the rubber gasket is padded in the guide groove, and the rubber gasket is padded in the fastening piece.

The beneficial effects of the utility model reside in that: the cable can be manually moved by an operator through the device, the operation is simple and convenient, the phenomena that the cable drags the ground and the like are effectively avoided, and the efficiency of tunnel construction is greatly improved.

Drawings

Fig. 1 is a side view of the structure of the present invention;

fig. 2 is a schematic structural view of the guide groove of the present invention;

in the figure: the device comprises a pulley 1, a cantilever 2, a connecting rod 3, a hinge rod 4, a guide groove 5, a fastening piece 6 and a connecting lug 7.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in figures 1 and 2, the cable towing device for tunnel construction comprises stand columns which are arranged at intervals along one side of a tunnel, the interval between every two adjacent stand columns is 2-3 m, a steel wire rope is connected between the stand columns, and a plurality of towing components used for hanging cables are movably connected onto the steel wire rope.

The towing assembly component comprises a pulley 1 hung on a steel wire rope, two sides of the pulley 1 are respectively connected with a horizontally arranged cantilever 2, the cantilever 2 and the pulley 1 are hinged through a pin shaft, and the front end of the cantilever 2 is U-shaped. Collude between two cantilevers 2 and be equipped with the connecting rod 3 of V-arrangement, the lower extreme of connecting rod 3 is equipped with two vertical L shape articulated rods 4, and articulated between two articulated rods 4 have a guide way 5 that is used for accepting the cable, leaves the clearance that supplies the cable to pass between guide way 5 and the connecting rod 3. The guide groove 5 is in a bent pipe shape, and fastening pieces 6 used for compressing the cable are arranged at two ends of the guide groove 5. Fastening plate 6 is C shape, all is equipped with engaging lug 7 on fastening plate 6 and the guide way 5, passes through the screw rod between stationary blade and the guide way 5 and is connected. In order to prevent scratching of the cable, rubber pads are lined in both the guide groove 5 and the fixing sheet.

The working principle of the utility model is as follows:

when the device is used, the upright posts are firstly arranged along one side of the tunnel, and the steel wire ropes are bound and fixed on the upright posts. And reasonably arranging towing cable assemblies on the two adjacent upright posts according to the length of the steel wire rope between the two adjacent upright posts, wherein the interval between the two adjacent towing cable assemblies is generally 40-50 cm. Then pass the cable guide way 5 to use the stationary blade fastening to fix the cable, collude connecting rod 3 on cantilever 2 again, the cable is hung promptly and is established in tunnel one side. When the cable needs to move forwards, the pulley 1 is dragged along the steel wire rope, and when the upright posts are added forwards and the cable needs to move forwards, the pulley is pulled forwards. Firstly, a pulley 1 is added on a newly-added steel wire brush, then a connecting rod 3 on a rear side sliding wheel 1 is taken down and hung on the pulley 1 at the front end.

It should be noted that the above are only some embodiments of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
