Problems solved by technology

[0003] Although CN 204472948 U discloses a lead screw moving type pole climbing robot, the robot has complex structure and poor adaptability
[0004] A gas-driven pole-climbing robot is disclosed in ZL200620088771.1. The power source of this robot is pneumatic, and the power source is inconvenient to obtain, resulting in unstable operation and unable to adapt to the climbing requirements of remote control.

Embodiment 1

[0036] Such as Figure 1-3 , a climbing robot used for inspection and maintenance of nuclear power pipelines, which includes an upper clamping mechanism 1 and a lower clamping mechanism 3 for clamping the pipeline, and the upper clamping mechanism 1 and the lower clamping mechanism 3 are connected by a The lifting mechanism 2 that drives its lifting is connected. The upper clamping mechanism 1 and the lower clamping mechanism 3 adopt the same structure. The above-mentioned climbing robot can be used for inspection and maintenance of nuclear power pipelines. During the working process, by remotely controlling the above-mentioned robots, the nuclear power pipelines can be smoothly climbed, thereby ensuring the safety of operators.

[0037] Further, the upper clamping mechanism 1 includes a base plate 4, on which a motor connecting plate 14 and a plurality of L-shaped connecting plates 12 are fixedly installed, and two wires are supported and installed between the L-shaped conne...

Embodiment 2

[0044] Any one of the operation methods for nuclear power pipeline inspection and maintenance climbing robot, it includes the following steps:

[0045] Step1: In the initial state, the splints 5 of the upper clamping mechanism 1 and the lower clamping mechanism 3 of the robot clamp the pipe, and the distance between the upper clamping mechanism 1 and the lower clamping mechanism 3 is the closest within the adjustment range of the lifting mechanism 2, and then execute The following steps;

[0046] Step2: The motor 7 in the upper clamping mechanism 1 reverses, drives the reducer 8 to drive the driving gear 9 to rotate, and drives the driven gear 10 to rotate through gear meshing. Since the driven gear 10 is installed on the two screw shafts 6, the two screw The bars are connected by a coupling 11, and the two threads are opposite, and the two splints 5 move toward each other to loosen the pipeline to be inspected;

[0047] Step3: The stepper motor 16 in the lifting mechanism 2 ...

Abstract

The invention discloses a climbing robot for nuclear power pipeline detection and maintenance and an operation method. The climbing robot comprises an upper layer clamping mechanism and a lower layerclamping mechanism which are used for clamping a pipeline and connected through a lifting mechanism for driving the upper layer clamping mechanism and the lower layer clamping mechanism to rise and fall. The upper layer clamping mechanism and the lower layer clamping mechanism adopt the same structure. The robot can be used for climbing on the outer wall of the vertical pipeline of a nuclear powerplant, remote control of detecting personnel is facilitated, thus the radioactive pipeline outer wall is detected, and the safety of operators is ensured.

Description

technical field [0001] The invention relates to the field of climbing equipment, in particular to a climbing robot and an operation method for nuclear power pipeline inspection and maintenance. Background technique [0002] With the increase of the operating time of nuclear power plants, the outer surfaces of pipes of various specifications need to be inspected and maintained regularly, and some of them also involve the weld seam inspection of pipes. These parts are located in the radiation area, and personnel should minimize the working hours. When facing vertical pipelines that need to be inspected, it is necessary to develop a climbing robot to replace manual labor to perform automatic climbing inspections on nuclear power pipelines. [0003] Although CN 204472948 U discloses a lead screw mobile type pole-climbing robot, the robot has complex structure and poor adaptability. [0004] A gas-driven pole-climbing robot is disclosed in ZL200620088771.1. The power source of t...
