Problems solved by technology

[0002] When laying cables at the cable branch box, ring network cabinet, and box-type transformer power supply inlet, it is necessary to make and install the cable terminal head, and the insulated core of the cable head must be shaped to facilitate the cable head connection operation; during cable maintenance It is often necessary to reshape and straighten the original cables. In the prior art, since there is no special cable straightening and shaping tool, it can only be manually operated to directly reshape the cable core. The disadvantage of this method is: It is time-consuming and labor-intensive to straighten and reshape the cross-section cable core, the labor intensity is high, the shaping effect is not good, the construction efficiency is low, and it is easy to cause damage to the insulation core and dirt on the surface of the insulation layer, which affects the safe operation of the cable after it is put into operation.

Abstract

The invention discloses a cable straightening pulley bracket which comprises a channel steel type frame, a transverse board, upper pulleys and lower pulleys. The transverse board is fixed above the lower edge of the channel steel type frame. More than two hanging shafts are arranged on the transverse board. The number of the lower pulleys is more than 2. The lower pulleys are hanged on the hanging shaft through central holes. Each upper pulley is provided with a central hole and is connected with the middle part of the upper edge of the channel steel type frame through a through shaft bracket and a lead screw pair. The cable straightening pulley bracket can perform straightening shaping on the cables with various kinds of bending shapes. Furthermore the cable straightening pulley bracket has advantages of saving time and labor in cable construction, reducing labor intensity, improving construction efficiency and ensuring high cable mounting quality.

Description

technical field [0001] The invention belongs to the technical field of cable tools, in particular to a cable straightening pulley bracket. Background technique [0002] When laying cables at the cable branch box, ring network cabinet, and box-type transformer power supply inlet, it is necessary to make and install the cable terminal head, and the insulated core of the cable head must be shaped to facilitate the connection operation of the cable head; when the cable is overhauled It is often necessary to reshape and straighten the original cables. In the prior art, since there is no special cable straightening and shaping tool, it can only be manually operated to directly reshape the cable core. The disadvantage of this method is: It is time-consuming and labor-intensive to straighten and reshape the cross-section cable core, the labor intensity is high, the shaping effect is not good, the construction efficiency is low, and it is easy to cause damage to the insulation core a...
