Abstract

A power cable tensioning device comprises a clamping hoop. An external thread is arranged on the outer side of the clamping hoop, and a clamping nut is arranged in cooperation with the outer wall of the clamping hoop. The clamping nut is composed of two semi-rings, wherein the side of each semi-ring is provided with a convex head and a concave groove, and the convex heads are matched with the concave grooves. A hanging hole is formed in the outer side of each semi-ring, and a traction rope is arranged in each hanging hole correspondingly. The power cable tensioning device further comprises a support. The lower side of the support is hinged to a base. The two sides of the upper end of the support are each provided with a hanging ring. Each hanging ring comprises an upper roller and a lower roller. Stop rods are arranged on the two sides of each lower roller. The traction ropes wind across the upper rollers and the lower rollers and then are provided with a tray. Cylindrical pressing blocks are borne on the tray. A through groove is formed in each pressing block in the radial direction of the pressing block. Each pressing block is provided with a bent groove. The tail end of each bent groove is communicated with the tail end of the inner side of the corresponding through groove. A telescopic device is arranged on the base, one end of the telescopic device is fixed on the base, and the other end of the telescopic device is hinged to the support.

Description

technical field [0001] The invention relates to a power cable tensioning device. Background technique [0002] During the transmission of electric energy in the cable, especially in the long-term transmission process, the cable is prone to bending and falling under its own gravity; on the one hand, the length of the transmission cable will increase, and on the other hand, it will also form The arc electric field is not conducive to the ground and lightning weather. [0003] The existing tensioning devices are relatively complicated, inconvenient to use and not effective in tensioning. Contents of the invention [0004] The object of the present invention is to overcome the disadvantages of the prior art and provide a power cable tensioning device, which has the advantages of simple structure and good tensioning effect compared with the prior art. [0005] In order to solve the problems of the technologies described above, the technical solution of the present invention i...
