Problems solved by technology

[0002] Due to the long-term use of the cable and the harsh environment, the surface protection layer is often damaged, causing the internal steel wire to break and warp. The climbing robot is easily caught when passing through these obstacles, and is forced to stay on the high-altitude cable and cannot successfully return to the ground.
And the climbing robot stays on the high-altitude cable, which is very dangerous in itself

Embodiment 1

[0056] Such as Figure 4 As shown, each probe 2 includes an arc-shaped probe 21 and a needle valve 22 .

Embodiment 2

[0058] Such as Image 6 As shown, each probe 2 includes an arc-shaped probe 21 and two needle valves 22 arranged parallel to each other.

[0059] Alternatively, the number of needle valves 22 may be three or more, all of which are within the protection scope of the present application.

[0060] One end of each needle valve 22 is fixedly connected to the arc probe 21 , preferably the top end of the needle valve 22 is fixedly connected to the middle of the arc probe 21 .

[0061] The other end of the needle valve 22 is floatingly connected to the switch body 3 , and the needle valve 22 can trigger the switch on and off of the switching signal in the switch body 3 .

[0062] The arc-shaped probes 21 are arranged coaxially and can be enclosed to form a ring structure. Preferably, the ends of the arc-shaped probes 21 are spliced ​​together to form a ring. As an alternative, the head and tail of the arc probe 21 can only be close to each other without splicing relationship, or th...

Abstract

The invention discloses a probe-type obstacle detection device for a high-altitude cable climbing robot, which comprises a ring-shaped probe and a switch body. The switch body includes a switch body including an inductive switch connection block and two elastic connection blocks. After adopting the above structure, while the cable is fully tested in the direction of the entire circumference, the above-mentioned needle valve is fixedly connected with the elastic connection block, and a floating elastic support connection can be performed between the needle valve and the induction switch connection block. Under the action, it can realize the movement of 6 degrees of freedom in space, which ensures that when the probe touches any obstacle of any shape at any position, the spherical contact can contact the ball socket inside the sensor switch connection block at any position and with any posture. , to generate a switching signal.

Description

technical field [0001] The invention relates to an obstacle detection device, in particular to a probe-type obstacle detection device for a high-altitude cable climbing robot. Background technique [0002] Due to the long-term use of the cable and the harsh environment, the surface protection layer is often damaged, causing the internal steel wire to break and warp. The climbing robot is easily caught when passing through these obstacles, and is forced to stay on the high-altitude cable and cannot successfully return to the ground. And the climbing robot stays on the high-altitude cable, which is very dangerous in itself. Therefore, obstacle detection of robots is an urgent technical problem to be solved. [0003] In response to this problem, this case innovatively designed an obstacle sensing device applied to a high-altitude cable crawling robot, which can detect obstacles on the path ahead in a timely and accurate manner during climbing and descending. Once an obstacle ...
