Cable tensioning device

Abstract

The invention relates to the field of inhaul cable pre-stressed structure construction devices, in particular to an inhaul cable tensioning device. In the prior art, the inhaul cable tensioning construction adopts manual construction through a wrench, the labor intensity is high, the construction is dangerous and cannot be constructed in extreme environment. The invention provides the inhaul cabletensioning device. The inhaul cable tensioning device comprises a node plate, a fork ear anchorage device, a connecting nut and a connecting anchorage device which are connected in sequence. The nodeplate is used for connecting with a connecting inhaul cable or a building, the fork ear anchorage device is connected with the node plate through a pin shaft, and the connecting anchorage device is internally connected with an inhaul cable; and the inhaul cable tensioning device further comprises a power device, the input end of the power device is used for connecting with a remote control deviceto realize the purpose of remotely controlling the rotation of the connecting nut, and the output end of the power device is connected with the connecting nut and used for driving the connecting nutto rotate. Compared with the prior art, the inhaul cable tensioning device has the advantages of low labor intensity, suitability for extreme environments, and safe use.

Description

technical field [0001] The invention relates to the field of cable prestressed structure construction devices, in particular to a cable tensioning device. Background technique [0002] During the construction of the cable structure, the cable must be tensioned. The so-called tension is to screw the connecting nut to drive the positive and negative internal threads of the connecting anchor and the lug anchor to achieve the purpose of applying prestress to the cable body. The tightening construction of the connecting nut in the conventional tensioning construction is realized by manpower with the corresponding wrench. The disadvantages of this method are as follows: [0003] 1. The construction consumes a lot of manpower and the effect is not ideal; [0004] 2. Tool damage often occurs; [0005] 3. The danger of high-altitude operations, workers cannot construct in extreme cases; [0006] 4. Tensioning construction often has a large force value, ranging from tens of tons to...
