Embodiment Construction

[0013] see figure 1 , figure 1 It is a schematic structural diagram of the rope climbing robot of the present invention. Depend on figure 1 It can be seen that the rope climbing robot of the present invention includes an active trolley 1 and a driven trolley 2. The active trolley 1 and the driven trolley 2 are arranged symmetrically on the left and right sides. Both the active trolley 1 and the driven trolley 2 have two wheels 7. The trolley 1 and the driven trolley 2 are connected to each other through a connecting piece, and a four-link tensioning mechanism 9 is arranged on the driven trolley 2. The structure of the four-link tensioning mechanism 9 is as follows: figure 2 , including four connecting rods 13, an adjusting screw 14, an adjusting nut and an adjusting spring 12, the four connecting rods 13 are connected into a parallelogram structure by four connecting pieces, and the adjusting screw 14 is threadedly connected in two of them. The adjusting screw 14 is provid...

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...
