Problems solved by technology

[0003] Since the spanning distance of the network sealing is not fixed, and the existing network sealing device technology is not perfect enough, the length of the network sealing cannot be quickly adjusted, so that the network sealing time is proportional to the length of the network sealing, resulting in low sealing efficiency and long network sealing time. The sealing network is a one-piece type, with low strength, and it is easy to be disconnected and caught in the network

Abstract

The invention discloses crossing and net blocking device for a high-voltage power transmission line. The device structurally comprises a crossing frame I, a net blocking mechanism I, a net blocking mechanism II and a crossing frame II, and the net blocking mechanism I is mounted on one side of the crossing frame I. Compared with the prior art, the beneficial effects of the invention are that: thetwo same net blocking machines are arranged in a combined manner, and the net blocking area is formed by splicing two nets and is provided with two support points, so the strength of the net blockingis greatly improved and broken lines are prevented from falling off the net; and due to the fact that the springs are telescopic, the spring rings are equidistantly increased or decreased when the springs stretch out and draw back, the length of the net blocking can be rapidly adjusted, the device can adapt to net blocking with different spanning intervals, the requirement for different net blocking lengths can be met, the net blocking efficiency is high, thenet blockingtime is short, and the stringing construction progress can be better improved.

Description

technical field [0001] The invention relates to the technical field of electric wires, in particular to a high-voltage transmission line spanning network sealing device. Background technique [0002] During the construction of high-voltage transmission lines, it is often encountered that they cross residential buildings, bridges, roads, railways, etc. In order to carry out the normal construction of transmission lines, it is necessary to straddle these facilities for network sealing construction. [0003] Since the spanning distance of the network sealing is not fixed, and the existing network sealing device technology is not perfect enough, the length of the network sealing cannot be quickly adjusted, so that the network sealing time is proportional to the length of the network sealing, resulting in low sealing efficiency and long network sealing time. The sealing net is a one-piece type, with low strength, and the phenomenon of disconnection and netting is easy to occur. ...
