Example one
Referring to fig. 1, fig. 1 is a schematic structural diagram of a nondestructive inspection robot for a power transmission line according to a first embodiment of the present application. As shown in fig. 1, the robot for nondestructive inspection of power transmission line includes: the device comprises a mounting platform 101, a line climbing mechanism 102, a line walking mechanism 103 and an X-ray nondestructive inspection detection mechanism 104.
One end of the line climbing mechanism is fixed on the mounting platform, and the other end of the line climbing mechanism is hooked on the power transmission line 105;
including extending structure in the line climbing mechanism, extending structure connects the one end and the other end of line climbing mechanism, when extending structure shortens, drives transmission line nondestructive test robot climbs to transmission line's target height.

In addition, one end of the line travelling mechanism is fixed on the mounting platform, the travelling end of the line travelling mechanism is fastened on the power transmission line, and the travelling end drives the line climbing mechanism, the line travelling mechanism and the X-ray nondestructive inspection detection mechanism which are fixed on the mounting platform to move along the power transmission line when travelling along the power transmission line.

Example two
Referring to fig. 2, fig. 2 is a schematic structural diagram of a line climbing mechanism according to a second embodiment of the present application. As shown in fig. 2, the present embodiment is described by taking an example in which the line climbing mechanism has two sets of telescopic structures.
Specifically, the line climbing mechanism that this embodiment provided can include at least two sets of extending structure, wherein, can include in every group extending structure: the climbing belt winding device comprises a wire hanging frame 1021, a climbing belt 1022, two winding devices and two climbing motors 1025, wherein each climbing motor is used for driving one winding device to rotate.
The hanging wire rack can be of a double-layer U-shaped structure, a hollow structure is arranged between the two layers of U-shaped structures, a climbing belt hole is formed, one end of the climbing belt is connected with one belt winder, and the other end of the climbing belt penetrates through the climbing belt hole to be connected with the other belt winder.
It should be noted that the winder can include winding wheel 1023 and winding wheel mounting 1024, wherein, the outer lane of winding wheel sets up to concave shape, and concave shape can help when the roll-up climbing area, for climbing area direction, makes the climbing area roll-up to concave shape's depressed part.
In addition, the shaft of the winding wheel is fixed on the winding wheel fixing piece in a rotatable mode, the winding wheel fixing frame can be triangular iron or a metal plate with any shape, and one end of the winding wheel fixing frame can be fixed on the mounting platform in a welding mode or a screw fastening mode.
The output shaft of climbing motor is connected with the through-drive of winding wheel, and when the output shaft of climbing motor rotated, the axle and the winding wheel that drive the winding wheel rotated, and the climbing area can be rolled up when the winding wheel rotated and is gone into this winding wheel or is released from this winding wheel. Wherein, the rotation direction of climbing motor can correspond take-up pulley roll-up climbing area or release climbing area respectively, for example, climbing motor corotation corresponds take-up pulley roll-up climbing area, and the climbing motor upset corresponds take-up pulley release climbing area.
As shown in fig. 2, in a set of extending structure, two winding winders roll up or release a climbing belt simultaneously, and the climbing belt passes through the climbing belt hole of the hanging wire frame, and the place contacting with the climbing belt hole is under the action of the gravity of the robot, and the place contacting with the climbing belt hole can be in a fixed state by the friction force and the elastic force between the climbing belt and the climbing belt hole.
When the two winding winders simultaneously wind the climbing belt, the climbing belt between the winding winders and the wire hanging frame is shorter and shorter, so that the purpose of shortening the telescopic structure is realized; when the two winding devices release the climbing belt simultaneously, the climbing belt between the winding devices and the wire hanging frame is longer and longer, and therefore the purpose of extending the telescopic structure is achieved.
In addition, the line climbing mechanism can also be provided with a gyroscope and a motor controller; the motor controller is in communication connection with the gyroscope and all climbing motors in the line climbing mechanism respectively and is used for controlling the rotating speed of each climbing motor according to signals of the gyroscope.
It should be noted that the gyroscope is a sensing gyroscope and is used for sensing whether the robot is in a horizontal state, and the motor controller controls the rotating speed of each climbing motor according to a sensing signal of the gyroscope. In a specific example, if the sensing signal of the gyroscope indicates that the robot is in a non-horizontal state, the winding or releasing speed of the winder at the end with the lowest relative position may be increased, so that the whole robot may be maintained in a horizontal state (i.e., the horizontal state of the mounting platform).
In order to guarantee that the line climbing mechanism can climb to the target height, the limiting device is further arranged in the line climbing mechanism and can be an infrared distance measuring instrument which comprises an infrared transmitting end and an infrared receiving end, the transmitting end can be arranged on the mounting platform, and the receiving end can be arranged on the wire hanging frame to measure the distance between the power transmission line and the mounting platform.

In addition, in another embodiment, a limiting inductor can be further arranged on each winding wheel, and the distance from the robot to the power transmission line is fixed during measurement, so that the thickness of the climbing belt wound on the winding wheels is fixed, and limitation can be realized by measuring whether the thickness of the climbing belt reaches a preset thickness.
Specifically, the infrared emitter and the infrared receiver can be arranged at the position of the winding wheel with a fixed thickness away from the recess, when the thickness of the wound climbing belt is higher than the position with the fixed thickness, the climbing belt can prevent the infrared rays emitted by the infrared emitter from reaching the infrared receiver, infrared receiver by receiving infrared conversion when unable received infrared ray, will send signal to motor controller, after motor controller received this signal, alright in order to control each climbing motor stop work.
It should be noted that, because each reel is provided with a limit sensor, and because of the existence of an error, the limit triggering time of each reel may not be the same, because in this embodiment, two sets of telescopic structures are respectively arranged on both sides of the mounting platform, for any telescopic structure, when the limit sensor of one reel is triggered, the shortening of the telescopic structure may be stopped, but the other telescopic structure needs to be continuously shortened until the limit sensor of the reel is triggered.

It should be noted that, when the nondestructive inspection robot of the power transmission line climbs to the target height of the power transmission line, the electric push rod pushes one end of the routing arm, where the routing wheel is installed, above the power transmission line, and at this time, the motor controller in the second embodiment controls the telescopic structure to extend for a distance, so that the routing wheel is clamped into the power transmission line, and thus the force for fixing the robot on the power transmission line is converted from the line climbing mechanism to the routing wheel, that is, the robot is suspended on the power transmission line through the routing wheel.
