Problems solved by technology

It is not only very difficult for construction workers to carry out long-distance transportation and installation of such heavy metal fittings at high altitudes, but also increases their own safety risks in high-altitude operations.
The Jiquan Line Project (Shaanxi 3 Bid Section) has the characteristics of large height difference and large gear distance. This traditional spacer transportation tool has no brake device, which cannot guarantee the smooth operation of oversized, The super-heavy spacer is installed, and the safety factor at the connection between the hook and the spacer is not enough, so there is a risk of the spacer falling during transportation

Abstract

The invention provides a high-altitude transportation device for a conductor spacer, comprising a self-locking assembly, wherein one end of the self-locking assembly is connected with a pulley assembly, the other end of the self-locking assembly is connected with a spacer temporary hanging plate piece. In comparison with a conventional high-altitude transportation device for a spacer, the high-altitude transportation device of the invention solves the problem of difficult transportation caused by large altitude difference and large span, greatly reduces a security risk of unhooking during thetransportation process of the spacer, and achieves stability, security and high efficiency.

Description

technical field [0001] The invention relates to the field of ultra-high voltage direct current transmission lines, in particular to a high-altitude transportation device for wire spacers. Background technique [0002] The Changji-Guquan ±1100kV UHV DC transmission line project is currently the UHV transmission project with the highest voltage level, the largest transmission capacity, the longest transmission distance, and the most advanced technology in the world. Our company is in charge of the Shaanxi 3 bid section of the project. North of Liugou Village (N6901), Shangzhou District, Shangluo City, Shaanxi Province, and ends at Changjiagou Nao (N7301), Shangnan County, Shangluo City, Shaanxi Province. The length of the route is 131.414km, and the altitude along the line is 400-1600m. The basic design wind speed of this bidding section is 27m / s, 30m / s, and the design ice coverage is 10mm, 15mm. JLB20A-240 aluminum clad steel strand, one is OPGW-240 composite optical cable. ...
