Problems solved by technology

[0003] At present, most wellbore inspections are manual inspections. Manual inspections have problems such as high risk, low efficiency, and inaccurate evaluation.
Therefore, robot inspection is a better alternative. The existing wellbore inspection robots mostly climb along the wire rope and can only move up and down in the vertical direction. During the climbing process, the wellbore is monitored. The monitoring area is controlled by the sensor. Due to the limitation of performance parameters (such as the limited field of view of the visual camera), it is difficult to realize all-round monitoring of the wellbore

Embodiment 1

[0028] Embodiment 1, a wind well inspection system, such as figure 1 , 2 , 3 and 4, including:

[0029] The horizontal circumferential traction mechanism includes two parallel and vertically arranged annular guide rails 1, the guide rails 1 are fixed to the inner wall of the wind shaft through a number of trusses 11 evenly distributed around the sides; the two guide rails 11 are equipped with mobile trolleys 2 , are respectively the upper mobile trolley and the lower mobile trolley, two groups of rollers are arranged under the mobile trolley 2, one group is the driving wheel 21, and is connected with a motor through the reduction box, and the other group is the driven wheel 22.

[0030] The upper surface of the guide rail 11 is provided with an L-shaped guide groove 111 downwards, and the inner sidewall of the guide rail 11 is a guide surface 112; the mobile trolley 2 is provided with two guide wheels, which are respectively a longitudinal guide wheel 23 and a transverse guid...

Embodiment 2

[0036] Embodiment two, such as Figure 5 As shown, the top of the upper guide rail 1 and the bottom of the lower guide rail 1 are equipped with a rotary platform 71 through the truss 7, and the ground traction device 31 and the underground traction device 31 are installed on the two rotary platforms 71 respectively.

[0037] Specific implementation instructions:

[0038] This embodiment provides another way to install the traction device 31 . The two traction devices 31 are respectively installed on the two rotary platforms 71 , so that the traction devices 31 can follow the movement of the moving trolley 2 and rotate in a direction, thereby ensuring the stability of the inspection robot 4 . This embodiment aims to provide users with another convenient installation method in different scenarios and environments.

Embodiment 3

[0039] Embodiment three, such as Figure 6 As shown, the ground traction device in this embodiment can be arranged on the ground other than the air shaft, and the underground traction device can be arranged at the bottom of the air shaft, but this will cause the steel wire rope 3 to be unable to move with the mobile trolley 2 when the traction motor 311 is stationary. synchronous rotation. For this reason, the traction motor 311 can be set to run synchronously following the movement of the mobile trolley 2 through the control module, thereby changing the length of the steel wire rope 3 between the traction motor 311 and the mobile trolley 2, so that the traction motor 311 can move away from the traction motor 311 when the mobile trolley 2 is away from the traction motor 311. 311 releases the steel wire rope 3 ; This has not only ensured the free movement of the mobile car 2, but also ensured that the height of the inspection robot remains unchanged. This embodiment aims to pro...

Abstract

The invention discloses an air well patrol system. The air well patrol system comprises a horizontal circumferential traction mechanism, a vertical traction mechanism and a patrol robot; the patrol robot comprises a robot shell, and further comprises a carrying table; an annular orbit is arranged on the carrying table; the orbit is connected with an image acquisition cradle head in a sliding manner; a rotating wheel is connected below the image acquisition cradle head through a driving motor; the rotating wheel is connected with the orbit in the sliding manner; a cable holding mechanism is fixed to the interior of the robot shell; the cable holding mechanism is fixed to the interior of the cable holding mechanism; the image acquisition cradle head comprises a camera, a control module and awireless transmission module; and a moving trolley, a motor, a ground traction device and a downhole traction device are all connected with the control module. The air well patrol system can move upand down in the vertical direction of an air well, monitor a wellbore in a climbing process, and can also perform all-directional monitoring on the circumferential direction of the wellbore. In addition, the air well patrol system is stable in operation and convenient to use, and can adapt to various complicated working environments.

Description

technical field [0001] The invention belongs to the field of mines, in particular to an air shaft inspection system. Background technique [0002] As an important part of my country's energy composition, coal is of great national strategic significance to ensure its safe mining. In the process of coal mining, in order to meet the survival needs of underground workers and the work needs of some equipment, it is necessary to connect fresh air from the ground to the ground. The air shaft is a shaft specially used for ventilation in the mine, and the air shaft is generally divided into an air inlet shaft and an air outlet shaft. The shaft that enters the fresh air is the air inlet shaft; the shaft that removes the dirty air is the air outlet shaft, and it is of great significance to ensure its safety. [0003] At present, most wellbore inspections are manual inspections. Manual inspections have problems such as high risk, low efficiency, and inaccurate evaluation. Therefore, ...
