Description

Major diameter cable laying device

Technical Field

The utility model relates to an electric power system technical field, concretely relates to major diameter cable laying device.

Background

With the continuous improvement of the requirements of the society on power consumption and power supply quality, the large-scale development of new construction or extension projects and the rapid increase of project floor area and electric equipment capacity, the problems of larger and larger project cable diameter, longer and longer laying path, easy cable fracture in the construction process, prolonged construction period and the like are caused, and the cable construction in a limited space can not be realized by the traditional manual laying.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the shortcoming that prior art exists, provide a major diameter cable laying device.

In order to realize the purpose, the technical scheme of the utility model is that: a large diameter cable laying apparatus characterized by: the cable drum comprises a cable drum, a cable drum bracket, a winch, a ground anchor, a tension sensor, a tension display controller, a relay and a plurality of cable rollers arranged along a cable laying path;

the bottom of the winch base is provided with a front row of pulleys and a rear row of pulleys, two parallel channel steel rails for the pulleys to slide left and right are arranged below the winch base, the channel steel track is fixed on the ground, the cable drum is arranged on the cable drum bracket, the steel wire rope of the winch sequentially rounds the roller groove of the cable roller on the laying path and then is connected with the cable of the cable drum, the ground anchor is arranged at the other end of the rope outlet end of the winch and is fixed on the ground, one side of the winch base, which faces the ground anchor, is provided with a pull ring I, a pull ring II is arranged on one side of the ground anchor facing the winch, the pull ring I and the pull ring II are on the same horizontal plane, the pull ring I and the pull ring II are respectively connected to the two ends of the tension sensor, the tension sensor is electrically connected with the tension display controller, and the relay is electrically connected with the tension display controller and the winch respectively.

Further, the method comprises the following steps of; the cable reel is characterized by further comprising a traction net sleeve, a cable of the cable reel is connected with a steel wire rope of the winch through the traction net sleeve, one end of the traction net sleeve is sleeved with the cable, and the other end of the traction net sleeve is fixedly connected with the steel wire rope.

The utility model has the advantages that:

1) the utility model is suitable for a large cross-section, long distance power cable lay, especially lay the cable laying of the big, limited project of operating space of the degree of difficulty in city utility tunnel crane span structure and in the building engineering cable shaft etc. do and be used for the cable laying engineering that the time limit for a project is nervous, personnel are not enough.

2) Because the winch can slide on the channel steel rail through the pulley, in the process of laying the cable dragged by the steel wire rope of the winch, the winch can transmit the pulling force to the tension sensor, the tension sensor feeds the pulling force signal back to the pulling force display control instrument, the on-off of the contactor of the winch is controlled through the pulling force display control instrument, and the damage to the cable structure caused by overlarge dragging force of the winch can be avoided.

In the figure: 1. a cable reel; 2. a cable reel support; 3. a winch; 4. a ground anchor; 5. drawing the net cover; 6. a tension sensor; 7, a tension display control instrument; 8. a relay; 9. a cable roller; 10. a pulley; 11. a channel steel rail; 12. a wire rope; 13. A cable; 14. a pull ring I; 15. and a pull ring II.

Detailed Description

Example (b):

as shown in fig. 1 to 3, a large-diameter cable laying device comprises a cable drum 1, a cable drum bracket 2, a winch 3, a ground anchor 4, a traction net sleeve 5, a tension sensor 6, a tension display controller 7, a relay 8 and a plurality of cable rollers 9 arranged along a cable laying path;

the bottom of the base of the winch 3 is provided with a front row of pulleys 10 and a rear row of pulleys 10, two parallel channel steel rails 11 for the pulleys 10 to slide left and right are arranged below the base of the winch 3, the channel steel rails 11 are fixed on the ground through expansion bolts, the cable drum 1 is installed on the cable drum support 2, a steel wire rope 12 of the winch 3 sequentially bypasses roller grooves of cable rollers 9 on a laying path and then is connected with a cable 13 of the cable drum 1 through a traction net sleeve 5, one end of the traction net sleeve 5 is sleeved with the cable 13, and the other end of the traction net sleeve 5 is fixedly connected with the steel wire rope 12; the ground anchor 4 is arranged at the other end of the rope outlet end of the winch 3, the ground anchor 4 is fixed on the ground through an expansion bolt, a pull ring I14 is arranged on one side, facing the ground anchor, of a base of the winch 3, a pull ring II 15 is arranged on one side, facing the winch, of the ground anchor 4, the pull ring I14 and the pull ring II 15 are on the same horizontal plane, and two ends of the tension sensor 6 are respectively connected with the pull ring I14 and the pull ring II 15; the tension sensor 6 is electrically connected with the tension display controller 7 through a signal cable, and the relay is respectively and electrically connected with the tension display controller 7 and the winch 3 through a signal cable 8.

When the cable is laid, the winch 3 is started, the steel wire rope 12 is tightened, the cable 13 is laid along with the steel wire rope 12 by bypassing the roller groove of the cable roller 9, the tension sensor 6 feeds a tension signal of the winch 3 back to the tension display controller 7, when the tension is smaller than a set value of the tension display controller 7, the winch 3 normally works, when the tension is larger than the set value, the tension display controller 7 outputs a disconnection signal to the relay 8, the relay 8 controls the contactor of the winch 3 to be disconnected, the work is stopped, and the structural damage of the cable 13 caused by the overlarge traction force of the winch 3 is avoided.

The above-described embodiments are merely preferred and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
