Pay-off apparatus for electric power distribution network

Abstract

The present invention discloses a pay-off apparatus for an electric power distribution network, and relates to the technical field of electric power engineering construction equipment. The pay-off apparatus comprises a pulley, a wire output plate, and a wire draw plate; wherein the side surface of the wire draw plate is in an arc shape, one end of the wire draw plate at the arc shape side is fixedly connected with one end of the wire output plate through a connecting piece; the other end of the wire output plate opposite to the wire draw plate is provided with three contacts and three balance weights respectively connected with the contacts; and one end of each contact far away from the wire output plate is provided with a rotation connector. The play-off apparatus provided by present invention is simple in integral structure, wherein, the wire output plate is provided with the three contacts and the three balance weights, and each contact is provided with the rotation connector used for connecting a cable, so that pay-off operation of a three-phase cable can be achieved within one line output process, thereby improving work efficiency.

Description

technical field [0001] The invention relates to the technical field of electric power engineering construction equipment, in particular to a wire pay-off device for power distribution networks. Background technique [0002] At present, in the construction of power distribution network projects, the installation of cables generally adopts the method of manpower dragging or fixed mechanical setting out. When using the manual dragging method, it takes a lot of manpower. The per capita load on the flat ground is 30KG or the per capita load on the mountain is 20KG to set out the line. After the line is set out, it is pointed out that a large area of ​​crops or economic forests may be damaged. After the line is completed, the damaged crops and The liquidation and compensation of economic forests require high costs for reconstruction and construction. When using the fixed mechanical laying out method, first lay out the guide rope, and then use the guide rope to lay out the cable t...

Problems solved by technology

When using the manual dragging method, it takes a lot of manpower. The per capita load on the flat ground is 30KG or the per capita load on the mountain is 20KG to set out the line. After the line is set out, it is pointed out that a large area of ​​crops or economic forests may be damaged. After the line is completed, the damaged crops and Liquidation and compensation for economic forests, high cost of transformation and construction

When using the fixed mechanical laying out method, first lay out the guide rope, and then use the guide rope to lay out the cable through the fixed machine. Only one cable can be laid out at a time, and the cable can be laid out after repeating three times. , low work efficiency
