Abstract

The utility model discloses a hoisting apparatus for a tower ground wire in a transmission line. The hoisting apparatus comprises a 6-mm thick steel plate long handle. A clamping groove is formed at one end of the long handle; two Phi 15 x 45 screws are arranged side by side on a back arm at the lower part of the clamping groove; and a U-shaped screw is arranged at the other end of the long handle. The utility model has a novel and reasonable structural design; when in operation, the clamping groove is clamped on the angle iron of a tower groud wire bracket to be used as a rear support; the two Phi 15 x 45 screws are propped against the angle iron of the ground wire bracket to play the same role as a leverage supporting point and serve the fixing function; the U-shaped screw is used as the hanging point for the hanging hook of a hoisting tool; and the size of the hanging hole of the U-shaped screw can be adjusted according to the size of the hanging hook of the hoisting tool. The utility model ensures that the hanging point of an aerial ground wire is adjacent to a ground wire mounting sliding vehicle, an aerial ground wire optical cable can be raised as high as required; and a jack is not required to be rearranged, thereby reducing the work intensity of an operator on the tower. The utility model effectively solves the technical problems of large labor intensity and low work efficiency; and the utility model represents an ideal mounting tool for a tower ground wire in a 220 kV transmission line.

Description

Electric power line pole tower ground wire lifting utensil

Technical field the utility model belongs to electrician's utensil technical field, relates to a kind of 220kV electric power line pole tower ground wire lifting utensil.

Background technology is present, and in the transmission line construction process of 220kV electric pressure, overhead ground wire (optical cable) ground wire is also referred to as lightning conducter or optical cable) installment work, normally hang overhead ground wire by coaster.Since overhead ground wire can't be directly near the hitch point of head of mast, overhead ground wire can't use lifting gears such as jack to install to the distance of ground wire shaft tower hitch point in pulley stile, can only install pickaback by the staff, not only working strength is big, also has certain danger. and an overhead ground wire (optical cable) is installed the staff is tired out; And because overhead ground wire (optical cable) is heavier, when far away or two basic shaft tower height were inconsistent when the basic shaft towers distance of circuit two, two staff also can't implement to install with operational method pickaback.

The summary of the invention the purpose of this utility model is to solve big, the ineffective technical problem of prior art labour intensity, provides a kind of electric power line pole tower ground wire lifting utensil, to overcome the deficiencies in the prior art.

To achieve these goals, the utility model electric power line pole tower ground wire lifting utensil, it comprises 6mm steel plate long handle, an end of long handle is provided with draw-in groove, be provided with the screw of two Φ 16X45 on the bottom back of the body arm of draw-in groove side by side, the other end of said long handle is provided with U type screw.

The utility model structural design novelty, reasonable, during work, draw-in groove is stuck on the shaft tower ground line bracket angle bar as back support, two Φ 16X45 screws withstand on and play balance pivot and fixing on the ground line bracket angle bar, and U type screw is used as the hanging point of lifting gear hook, and the big I of hanging hole of U type screw is regulated according to the size of using the lifting gear suspension hook.It is close that the utility model makes overhead ground wire hitch point and ground wire that coaster is installed, and the overhead ground wire optical cable directly can be risen to desired height, and need not switch jack, alleviated operating personnel's working strength on the shaft tower.Efficiently solve big, the ineffective technical problem of labor strength, the utility model is a kind of desirable 220kV electric power line pole tower ground wire erecting tools.

Appended drawings is the utility model structural representation.

Embodiment with reference to the accompanying drawings, it comprises 6mm steel plate long handle 3 the utility model, an end of long handle 3 is provided with draw-in groove 1, is provided with the screw 2 of two Φ 16X45 on the back of the body arm of the bottom of draw-in groove 1 side by side, the other end of long handle 3 is provided with U type screw 4.

Concrete application process: in engineering construction, the staff is when carrying out overhead ground wire optical cable card line, at first the utility model is installed on the ground line bracket angle bar, upper end with jack hangs on the link of U type screw then, ground wire is hooked in the lower end of jack, promote ground wire when being tightened to suitable distance with jack, overhead ground wire put the coaster that ground wire uses from exhibition be put in the ground wire wire clamp of the first dress that is connected with shaft tower ground wire hitch point, fastening then ground wire wire clamp screw can be finished ground wire and install.
