Cable-climbing robot

Abstract

The invention relates to a cable-climbing robot used for detecting poly ethylene (PE) damage on the surfaces of cables in a suspension bridge and a cable-stayed bridge, wherein the cable-climbing robot comprises a driving trolley (1) and a driven trolley (2) which are arranged symmetrically on the left and right sides; both the driving trolley (1) and the driven trolley (2) are provided with two wheels (7) and connected with each other through a connecting piece; a four-connecting-rod tensioning mechanism (9) is arranged on the driven trolley (2) and comprises four connecting rods (13), an adjusting screw rod (14), an adjusting nut and an adjusting spring (12); a climbing mechanism is arranged on the driving trolley (1) and comprises one pair of helical gears with matched right angles, a direct current motor (5) and a transmission chain (6); And V-shaped grooves are arranged on the wheels (7) of the driving trolley (1) and the driven trolley (2). The cable-climbing robot is applied to the surfaces of various cables used at present and is suitable for operation condition in high air; the commonality is good; rechargeable batteries are adopted for providing power; and the cable-climbing robot has simple structure design, and is convenient in maintenance and safe and reliable in operation.

Description

technical field [0001] The invention relates to a cable-climbing robot, in particular to a robot for detecting PE damage on the surface of cables of suspension bridges and cable-stayed bridges. It belongs to the field of robotics. Background technique [0002] With the continuous development of bridge construction, new large-scale cable-stayed and suspension bridges have been widely used. As the main force-bearing mechanism of this kind of bridge, the quality of the cable directly determines the service life of the bridge. The polyethylene (PE) protective layer on the surface of the cable is exposed to the air of the river and the sea for a long time, and will be damaged by different degrees of aging and hardening. At the same time, due to the strong wind and rapid rain on the river and sea surface, the cable will generate wind and rain shocks under the action of wind and rain, so now spiral lines or embossed pits are made on the PE layer of the cable surface, or a combina...

Problems solved by technology

Some scientific research institutions have also done corresponding research, such as the robot developed by Shanghai Jiaotong University, patent number 99252056.8, this robot can better complete the coating maintenance function, but the structure is complex, heavy, and it uses cable power supply, which is affected by the working environment Large, suitable for high-altitude long cable operation environment, and the detection efficiency is very low

These robots can partially meet the detection requirements, but the detection efficiency is low, occupying a long time on the bridge and affecting traffic
