a cable device

Abstract

The invention discloses a supporting rope device for supporting a reference steel rope and a target steel rope. The supporting rope device comprises a supporting rope system, at least two climbing andfixing systems and a traction system. The supporting rope system is used for rotatably being arranged on the target steel rope. Each climbing and fixing system comprises climbing roller supporting rods which are arranged vertically, fixed roller support rods of which the bottom ends are rotatably connected with the climbing roller supporting rods, and first driving mechanisms. Climbing rollers are arranged on the climbing roller supporting rods, and fixed rollers are arranged on the fixed roller support rods. The first driving mechanisms are used for driving the fixed roller supporting rods to move towards the direction near the climbing roller support rods and enabling the fixed rollers and the climbing rollers to clamp the reference steel rope. The traction system is connected with a clamping fixing system. The supporting rope device can adjust the position, the climbing rollers and the fixed rollers are used for clamping the reference steel rope, so that the steel rope is preventedfrom jumping from a groove, and at the same time, the problem that a wire of the reference steel rope is broken due to the fact that the reference steel rope is abrasive caused by the frequent relative movement between the supporting rope device and the reference steel rope is avoided.

Description

technical field [0001] The invention relates to the field of bridge construction devices, in particular to a support cable device. Background technique [0002] During the erection of high-altitude cables or the operation of cableways, due to the softness and low rigidity of the cable body itself, due to the wind load at high altitude, there will be mutual interference between the upper and lower layers or the left and right adjacent cable bodies, or even winding. At present, the common support cable devices are installed on the reference steel cables, one is set every 30-50m, and a connecting rope is arranged between every two adjacent support cable devices to connect all the support cable devices in series. In use, the stay cable device rests on the reference wire rope, and the target wire rope rests on the stay rope system. [0003] Common stay rope device has the following deficiencies: [0004] (1) During the operation, the support cable device rests on the reference ...

AI Technical Summary

Problems solved by technology

[0004] (1) During the operation, the support cable device rests on the reference steel cable, and the cables and cableways generally cross mountain streams, valleys or rivers. The gorge wind in such terrain has high wind speed and changeable wind direction, which is very easy to Cause the reference wire rope to vibrate violently, make the support cable device resting on the reference wire rope vibrate, thus causing the wire rope to jump, and the frequent relative movement between the support wire device and the reference wire rope will also wear the reference wire rope, which is easy to cause The reference cable breaks at the edge of the wheel groove of the support cable device

[0005] (2) It cannot be relatively fixed, so that the position of the support cable device cannot be adjusted at any time according to the actual intersection point of the steel cable. If the position of the support cable device needs to be adjusted, only artificial high-altitude operations can be used

At the same time, due to the influence of the self-weight of the support cable device itself, it cannot be applied to areas with large side spans such as cables and cableways.

[0006] (3) The target steel cable rests on the support cable system, which is only applicable to the situation where the distance between the upper and lower steel cables is large and there is no cross interference. When the distance between the upper and lower steel cables is small or due to simultaneous force If the degree changes, it will interfere with each other. At this time, the upper and lower interfering cables cannot be opened, resulting in the friction and damage of the cables.

[0007] (4) The horizontal spacing of the rollers of the supporting cable device in contact with the reference cable is relatively fixed, and can only be used on a constant spacing or a single reference cable, and cannot be used on multiple reference cables with equal variable spacing on the side span of the cable crane (Because the transverse spacing of the reference steel cables on the main cable saddle of the cable crane is fixed, and the positions of the reference steel cables on the side spans on the anchor points are different from each other, the transverse spacing of the reference steel cables on the whole side span is gradual)
