Description
Technical field
The utility model relates to transmission line of electricity Guywire tower installation Technology field, specifically a kind of anchoring instrument.
Background technology
In Brazilian transmission line of electricity, widely, wherein make somebody a mere figurehead in transmission line of alternation current on 500kV common-tower double-return road, Guywire tower proportion reaches 80% in the application of Guywire tower, and the installation of Guywire tower is the groundwork amount of overhead line structures construction.
Guywire tower tower engineering divides ground group tower and Li Ta two operations, and its neutral tower operation is exhaled according to steel tower and held high difference, lifting place situation is divided into again entirety to stand up and segmental hoisting two kinds.
In the common-tower double-return overhead wire of 500kV and above, Guywire tower integral hoisting needs to use large-tonnage truck crane, the requirement of large-tonnage truck crane to lifting place and mechanical road of marching into the arena is very high, construct in wood land, a large amount of trees need be cut down, drop into substantial contribution, difficulty of construction is large and do a lot of damage to Ecological environment.
Tower lifting construction is found in Guywire tower segmentation, because the fixed point of steel tower bracing wire is at steel tower epimere, therefore after hypomere steel tower stands up, needs to use temporary guy to carry out anchoring temporarily to steel tower, after whole tower crane installs into, after formal bracing wire being installed, then removes temporary guy.
The formal stayguy material of steel tower is stranded galvanized steel, " metal parts of pull wire " is installed at bracing wire two ends, bracing wire upper end is connected on the junction plate of steel tower, lower end is connected on the pre-buried gold utensil in stay rod basis, Lever Blocks need be used when bracing wire is installed bracing wire is tightened up, Lever Blocks suspension hook need be connected on stay rod basis, and chain suspension hook is connected on " fixing-line device " that be filled in advance in bracing wire, tightens up bracing wire and be finally fixed on metal parts of pull wire by Lever Blocks.
Temporary guy uses material to be wire rope, and wire rope upper end is connected on iron tower main material by suspender belt, and lower end is connected on the pre-buried gold utensil in stay rod basis, and Lever Blocks is installed in wire rope lower middle portion, for tightening up temporary guy.
Formal bracing wire lower end needs to be connected on the built-in fitting gold utensil of stay rod basis, and temporary guy also needs to be connected on basic built-in fitting gold utensil, but the pre-buried gold utensil top headspace of stay rod is too little, cannot connect temporary guy and formal bracing wire simultaneously.In addition, when installing formal bracing wire, tightening up bracing wire Lever Blocks used cannot take root, and bracing wire cannot be installed, and Guywire tower segmental hoisting scheme cannot be implemented.
At home and abroad on market, do not have the bracing wire pretension special tool that can meet construction requirement, the transmission line of electricity Guywire tower installation of 500kV and above also just cannot select the scheme of " segmental hoisting founds tower ".
Utility model content
Present Problems existing:
The tower position in forest or region with a varied topography, road and geological conditions can not meet large-tonnage truck crane and to march into the arena requirement, and Guywire tower cannot carry out integral hoisting, and little tonnage crane can only be used to carry out " segmental hoisting founds tower ".
" segmental hoisting founds tower " need use temporary guy to carry out anchoring temporarily to steel tower, has lifted rear temporary guy and need be replaced by formal bracing wire, and tightens up formal bracing wire Lever Blocks used and cannot take root.
In order to solve the deficiencies in the prior art, a kind of special tool must be had, can fix " temporary guy ", the Lever Blocks tightening up " formal bracing wire " can be fixed again, complete the transition of two kinds of bracing wires.
The utility model solves the technical scheme that its technical problem adopts:
