JPH052521U - Cable guide tip cap - Google Patents

Abstract

(57) [Abstract] [Purpose] The present invention is to smoothly draw a cable by using a connecting member made of a shackle and a twisted metal object without being caught in a metal wheel or roller when laying or crossing a cable. [Constitution] A conical tube is integrally formed at one end of an aluminum cylindrical tube having a diameter capable of accommodating a connecting member composed of a shackle, a twisted metal object, and a shackle, and the length of the cylindrical tube and the conical tube is set to the connecting member and a cable end. The cap is configured to have a length that can store the. With the cap of the present invention, the cable can be smoothly moved without catching the connecting member, and the cable can be smoothly towed without applying unnecessary tension.

[Prior Art]

 Fig. 5 shows the conventional means for pulling the cable during cable laying in a conduit and installation of overhead cables. In the figure, 10 is a connecting member, 11 is a shackle, 12 is a twisted metal object, 13 is a free line grip at the tip of a cable, 13-1 is a connecting portion, 14 is a tow rope, 15 is a gold wheel and a roller. FIG. 6 shows a partial cross-sectional view of the structure of the twisted metal product 12. In the figure, 16 is a right rotating body, 17 is a left rotating body, 18 is a connecting body, 19 is a bearing of the connecting body, 20 is a rotating shaft integrally provided in the right rotating body, and 21 is fixed to the tip of the rotating shaft. , A tool for preventing the right rotating body 16 from coming off. The left and right rotating bodies 16, 17 are connected by a central connecting body 18, and the right rotating body 16 can freely rotate by a bearing 19 of the connecting body 18. As shown in the figure, the free end of the cable is gripped by the free-line grip 13, the connecting portion 13-1 at the tip of the free-line grip 13 is connected to the shackle 11, and the tow line 14 is connected to the other shackle 11. Then, the pull rope 14 is pulled to pass the gold wheel and the roller 15 to lay the wire.

[Problems to be solved by the device]

 The disadvantage is that the connecting part has a complicated shape, so if the bending part and the towing are temporarily stopped for some reason, the cable tip accidentally stops just before the wagon, etc. It is dangerous because tension is applied more than necessary.

[0003]

[Means for Solving the Problems]

 A conical tube is integrally formed at one end of a straight-diameter aluminum cylindrical tube that can store a connecting member composed of a shackle, a twisted hardware, and a shackle, and the length of the cylindrical tube and the conical tube accommodates the connecting member and the cable end. The cable guide tip cap is configured to allow this.

[0004]

[Operation] When the connecting member is housed in the cable guide end cap, the cable and the towline are connected to the connecting member, and the towline is towed, the thin end of the conical tube can pass through metal objects, rollers, etc. It can be towed smoothly without being caught as in the past, and work can be performed safely.

【Example】

 FIG. 1 is a perspective view of a cable guide tip cap (hereinafter simply referred to as a cap) of the present invention, and FIG. 2 is a front view seen from the arrow direction of FIG. The structure of the cap of the present invention will be described. The cap of the present invention has a conical tube 1-2 integrally formed at one end of an aluminum cylindrical tube 1-1 having a diameter large enough to accommodate a connecting member composed of a shackle, a twisted metal object and a shackle. The conical tube has an integral length, which accommodates the connecting member 10, connects the shackle 11 to the tow line 14, and connects the other shackle 11 to the free line grip 13 at the end of the cable at the connecting portion 13-1. Then, when the tow rope 14 is towed and the shackle 11 is brought into contact with the conical tube 1-2, the free line grip 13 at the tip of the cable has such a length as to be located in the cylindrical tube 1-1. The state diagram is shown in FIG.

FIG. 4 is a diagram in which the cable is towed by a pulling rope 14 with a metal wheel and a roller in a state where the connecting member 10 is housed in the cap 1. By using the cap 1 of the present invention, the complicated shape of the connecting member 10 can be treated as a cylindrical tube having a conical tube at its tip, and it can be smoothly moved without being caught even at a bend. There is no trouble such as a temporary stop, etc., and tension is not applied to the cable more than necessary.

[0007]

[Effect of the device]

 Since the cap of the present invention has the structure as described above, the cap can be used to prevent catching on a gold wheel or the like during cable laying and crossing, which improves work efficiency and allows the cap to be caught as before. As a result, it is possible to prevent the cable from being subjected to more tension than is necessary for towing.
