Embodiment Construction

[0008] The embodiment is described in detail in conjunction with the accompanying drawings. In the present invention, a connecting plate 2 protruding outward in an arc shape is respectively welded on the side walls of one end of a metal semicircular tube groove plate 1, and a connecting plate 2 is installed between the middle parts of the two connecting plates. A fixed shaft 5 is installed with a pay-off pulley 3 with a bearing on the fixed shaft, and a U-shaped snap ring 4 is respectively arranged at the two ends of the fixed shaft 5 . The length of the above-mentioned grooved plate is 1-1.2 meters, and the inner diameter is 12cm. When it is used for laying cables underground, place it on the upper part of the laying cable, first clamp the pulley outside the plastic protective tube that needs to pass, then push the slot plate along the cable into the protective tube, the pulley stays at the outer end of the protective tube, and when the cable moves As the pulley rolls, the fr...

Abstract

The invention discloses a tackle for paying off an underground laid cable, and aims to provide the tackle which is used for paying off the underground laid cable and can relieve labor intensity and prevent a protective pipe from abrasion. According to the technical scheme, the tackle for paying off the underground laid cable comprises a semicircular pipe groove plate, wherein the two side walls of one end of the semicircular pipe groove plate are respectively provided with a connecting plate which outward protrudes in an arc-shaped mode, a fixing shaft is arranged between the middle portions of the two connecting plates, a paying-off pulley is arranged on the fixing shaft through a bearing, and the two ends of the fixing shaft are respectively provided with a U-shaped clamping ring. When the tackle is used, the pulled cable passes through the pulley and a paying-off groove, and therefore the tackle can be conveniently carried, installed and used, the protective pipe can be effectively prevented from abrasion, and labor intensity can be relieved.

Description

[0001] Technical field: [0002] The invention relates to a pay-off pulley used for preventing wear and tear of protective tubes when cables are laid in underground cable trenches. Background technique: [0003] At present, when laying cables in underground cable trenches, there is no special pay-off block. In order to prevent the plastic cable protective tube from being worn out when pulling the cable, some rubber pads are used for protection at the interface between the cable and the protective tube. , because the frictional force produced during unwinding is relatively large, the mat can only be used once, and it is still easy to wear and tear the protective tube, and the labor intensity is high. Invention content: [0004] The object of the present invention is to provide a cable pay-off block for underground laying that can reduce labor intensity and prevent abrasion of protective pipes. [0005] The technical solution of the present invention is accomplished in ...
