Embodiment Construction

[0009] A hydraulic multi-functional tensioner, including a hydraulic screw 1, a pressure reducing valve 2 and a manual hydraulic lever 3 are respectively arranged on the cylinder of the hydraulic screw 1, when the manual hydraulic lever 3 is pressed down by hand, the hydraulic screw lever 8 It will stretch out to the left. After depressing the pressure reducing valve 2, the hydraulic screw lever 8 will be retracted into the cylinder of the hydraulic screw 1. The hydraulic screw lever 8 is fixedly provided with a connecting pin 4 on the right side of the cylinder body of the hydraulic screw 1, and the head of the connecting pin 4 is sleeved in the rotatable left bracket 5, and the rotatable left bracket 5 A right loop chain 6 is connected on the right closed post of the right loop chain 6, and a right tight wire hook 7 is arranged on the right end of the right loop chain 6, and by freely rotating the left bracket 5 of a glyph shape, it can be adapted to the direction of the draw...

Abstract

The invention discloses a hydraulic multifunctional wire fastener. A pressure reducing valve (2) and a manual hydraulic rod (3) are arranged on a cylinder body of a hydraulic screw rod (1); a hydraulic screw lever (8) which is extended out from the left end of the cylinder body is arranged inside the cylinder body of the hydraulic screw rod (1); a connection pin (4) and a rotary square-shaped left support (5) are fixedly arranged on the lateral side of the right end of the cylinder body of the hydraulic screw rod (1); a right ring type chain (6) and a right wire fastening hook (7) are connected to a right sealing column of the rotary square-shaped left support (5); the head portion (9) of the hydraulic screw lever (8) is sleeved inside a rotary square-shaped right support (10); and a left ring type chain (11) and a left wire fastening hook (12) are connected onto a left sealing column of the rotary square-shaped right support (10). The hydraulic multifunctional wire fastener has the advantages of being light in weight, convenient to carry and simple to operate and solving the problems that the existing double-hook wire fastener is limited in extend and withdraw distance and large in labor intensity of operators.

Description

technical field [0001] The invention relates to a wire tightener, in particular to a wire tightener used for pulling two wires together when performing wire tightening operations on power transmission lines. Background technique [0002] Existing wire tightening tools for power transmission line operations mainly include double-hook wire tighteners, chain hoist wire tighteners and ratchet tension tighteners. The gourd-type wire tensioner has unlimited telescopic distance, but has the disadvantages of low approved tonnage and excessive weight. The double-hook thread tensioner has the advantages of light weight and convenient operation, but has the defects of limited telescopic distance and high labor intensity for the operator. Contents of the invention [0003] The invention provides a hydraulic multi-functional thread tensioner, which solves the problems of limited telescopic distance and high labor intensity of operators in the existing double-hook thread tensioner. ...
