Description

Apparatus to remove cable

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable demolition apparatus for demolishing a cable installed in an underground pipe or the like.

In general, the operator uses a vehicle equipped with an electric winch in the truck to remove the copper cable embedded in the underground, or uses a cargo crane. That is, when a vehicle equipped with an electric winch is used, the operator pulls the cable and drives the winch with the wire wound around the electric winch to remove the cable or remove the cable while moving the vehicle. Also, if you are using a cargo crane, tie the copper cable to a wire and tow it with a crane to remove the cable.

However, underground pipelines can not be easily removed due to the frictional force acting on the cables due to subsidence of pipelines, breakage of pipelines, or inflow of soil. Therefore, existing cable demolition methods have limitations in increasing the traction force. Conventional cable demolition method occupies a lot of work area and workforce for demolishing copper cable, which causes traffic congestion and causes complaints at work site.

A technique for solving such a problem is disclosed in Korean Patent Registration No. 10-0851196. The above-mentioned publication discloses a technique capable of demolishing a cable with a demolition device fixed and reducing a work area and a work force. However, it is necessary to more easily remove the cable embedded in the underground pipe by further increasing the pulling force for pulling the cable, but it can not sufficiently cope with the problem.

And the pair of third gears 27 can be coupled to the same shaft by the shaft member 3a.

The base 1 is provided with a support member 31 projecting upward. The shaft of the second gear 25 is coupled to one side of the tip of the support member 31. One side of the first link 33 is coupled to the shaft of the first gear 23 and the other side is coupled to the shaft of the second gear 25. That is, the support member 31 and the first link 33 are links that remain stationary without moving.

One end of the second link 35 is coupled to the shaft of the second gear 25, and the other end of the second link 35 is coupled to the shaft of the third gear 27. One end of the third link 37 is coupled to the shaft of the third gear 27 and the other end is coupled to the shaft of the fourth gear 29. Therefore, the portion where the second link 35 and the third link 37 are engaged, that is, the shaft portion of the third gear 27, can be moved. Therefore, the third gear 27 can be disengaged from the second gear 25 and the fourth gear 29 in accordance with the driving of the first subordinate drive source 19.

On the other hand, the second link 35 is provided with a latching jaw 35a (see Fig. 1) on one surface of the portion coupled to the first link 33.

That is, a second sub-drive source 41, which is a sub-drive source 7, is disposed on one side of the horizontal fixed member 39, and the second sub-drive source 41 may be a hydraulic cylinder in which the piston rod linearly moves. The first sub-driving source 41 is coupled to the second sub rotatable jig 15 by a separate bracket so as to move the second sub rotatable jig 15.

In other words, the second sub rotatable jig 15 can be moved to a position close to the outer circumferential surface of the main rotatable jig 5 while being moved by the second sub-drive source 41.

On the other hand, a drive sprocket (not shown) is provided on the same axis in the main drive source 3 or the main rotatable jig 5, and a driven sprocket 43 (see FIG. 2) is installed at a position spaced apart from the drive sprocket do. The driving sprocket and the driven sprocket 43 are connected to each other by a chain 45 to transmit the driving force to the driven sprocket 43 side.

The winch 47 is engaged with the driven sprocket 43. The winch 47 can rotate together with the main rotatable jig 5 in accordance with the driving of the main drive source 3. The winch 47 is a device capable of winding a cable or the like.

The operation of the embodiment of the present invention will now be described.

First, the operator connects the cut cable to the position wire. Then, the winch wire is connected to the winch 47 and the winch 47 is driven to pull the cable. At this time, the cable is arranged between the main rotatable jig 5 and the sub rotatable jig 9, that is, between the first sub rotatable jig 13 and the second sub rotatable jig 15. [ And drives the first subordinate drive source 19 and the second subordinate drive source 41. Then, the first sub rotatable jig 13 and the second sub rotatable jig 15 move toward the main rotatable jig 5, and are brought into close contact with the cable. Thus, the cable is in close contact with the main rotatable jig 5, the first sub rotatable jig 13 and the second sub rotatable jig 15.

This state is maintained such that the third gear 27 meshes with the second gear 25 and the fourth gear 29. In this state, the main rotatable jig 5 is rotated by the driving force of the main driving source 3 and at the same time, the driving force of the main driving source 3 is transmitted to the first gear 23, the second gear 25, 27, and the fourth gear 29 to the first sub turnable jig 13. Thus, the first sub rotatable jig 13 rotates in a direction opposite to that of the main rotatable jig 5. Therefore, the cable is brought into close contact with the main rotation type jig 5 and the first sub rotation type jig 13, and a pulling force is generated. Thus, an embodiment of the present invention can exert a great deal of effort in towing cables.

Further, since the embodiment of the present invention uses the power of the existing main drive source 3 as it is, no additional power source is required, and the additional manufacturing cost can be minimized.

The embodiments of the present invention are also applicable to the main rotating type jig 5 and the first and second rotating jigs 5 and 6 through gear ratios of the first gear 23, the second gear 25, the third gear 27, The sub rotatable jig 13 may be rotated so that the sub rotatable jig 13 does not rotate relative to the jig 13 but is interdigitated with the cable therebetween. Therefore, the embodiment of the present invention can pull the cable with stable operation, thereby enhancing the stability while giving great power to tow the cable.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
