Description

Technical Field

[0001] The present invention relates to the technical field of ventilation shaft inspection devices, and in particular to a high-efficiency ventilation shaft inspection device. Background Art

[0002] After a coal mine's ventilation shaft officially enters production, it serves as the mine's total return air, creating an extremely harsh environment. Few people enter it on a daily basis, making it difficult to monitor the safety facilities. However, the ladder room within the ventilation shaft, serving as the final evacuation route in the event of a major safety incident, requires enhanced inspection and maintenance of the shaft wall structure and internal ladder room to ensure that this vital passage remains unobstructed when in use.

[0003] Existing inspections of wind shafts are mostly done manually, which has low inspection efficiency and poor accuracy of inspection results due to observation by the naked eye of staff. Existing wind shaft inspection devices are only equipped with a single or two cameras, and the cameras need to be rotated to capture the image of the entire shaft wall, resulting in low shooting efficiency. For example, the "A Mine Shaft Inspection Robot" with application number "CN114314280A" is equipped with two cameras side by side. When it takes pictures of the shaft wall, it is necessary to rotate the rotating seat and move the mounting seat vertically to capture the image of the entire shaft wall. However, during the vertical movement of the mounting seat, since the two cameras are arranged side by side, even if the rotating seat rotates at the same time, the image of a part of the shaft wall cannot be captured due to the change in the vertical position of the mounting seat. Therefore, in order to capture the complete image, it is necessary to stand still in the vertical direction and wait for the rotation shooting to be completed, and then move in the vertical direction to capture images on the shaft wall at other heights. This method is time-consuming and labor-intensive and urgently needs to be improved. Summary of the Invention

[0004] Therefore, the present invention is made in view of the above problems, and provides a high-efficiency air shaft inspection device to solve the problem of low detection efficiency of existing air shaft inspection devices.

[0005] An efficient inspection device for the air shaft includes a lifting body, a lifter, a wire rope, a driving device, a rotating device, a central shaft body, and an inspection disk. A lifter is arranged on the side of the lifting body. The lifter is connected to a wire rope. A driving device is arranged on the other side of the lifting body. The lower part of the lifting body is connected to the central shaft body through a bearing. The rotating device is sleeved outside the central shaft body through a bearing connection. The rotating device includes: a rotating disk, a vertical rod, a connecting sleeve, and a first passive gear. Four vertical rods are arranged around the lower end of the rotating disk.

The upper end of the lead screw is coaxially and fixedly provided with a connecting shaft. The upper end of the connecting shaft is coaxially and fixedly provided with a second passive gear. The first passive gear is coaxially sleeved on the connecting shaft through a bearing connection, and the first passive gear is arranged below the second passive gear. The lead screw passes through the lower part of the rotating disk. The inspection disk is coaxially arranged below the rotating disk. The driving device is telescopic and meshes with the rotating device and the central shaft body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are easy to implement for those with ordinary skills in the art of the present invention. However, the present invention can be implemented in various different forms, so the present invention is not limited to the embodiments described below. In addition, in order to describe the present invention more clearly, components not connected to the present invention will be omitted from the drawings.

[0021] As Figure 1 , Figure 2 shown, an efficient inspection device for a ventilation shaft wellbore includes: a lifting body 1, a lifter 2, a wire rope 3, a driving device 4, a rotating device 5, a central shaft body 6, and an inspection disk 7; a lifter 2 is arranged on the side of the lifting body 1, and the lifter 2 is connected with a wire rope 3; a driving device 4 is arranged on the other side of the lifting body 1; the lower part of the lifting body 1 is connected to the central shaft body 6 through a bearing, and the rotating device 5 is sleeved outside the central shaft body 6 through a bearing connection.

[0022] As shown in Figure 2 , Figure 3 shown, the rotating device 5 includes a rotating disk 51, a vertical rod 52, a connecting sleeve 53, and a first passive gear 54. The lower end of the rotating disk 51 is vertically arranged and four vertical rods 52 are uniformly arranged around the rotating axis. The connecting sleeve 53 is coaxially and fixedly arranged at the upper end of the rotating disk 51, and the first passive gear 54 is coaxially and fixedly arranged at the upper end of the connecting sleeve 53. Through holes are formed in the rotating disk 51, the connecting sleeve 53, and the first passive gear 54.

[0023] As shown in Figure 2 , Figure 3 shown, the central shaft body 6 includes a lead screw 61, a second passive gear 62, a connecting column 63, and a connecting shaft 64. The upper end of the lead screw 61 is coaxially and fixedly provided with a connecting shaft 64, and the upper end of the connecting shaft 64 is coaxially and fixedly provided with a second passive gear 62. The first passive gear 54 is coaxially sleeved on the connecting shaft 64 through a bearing connection, and the first passive gear 54 is arranged below the second passive gear 62. The gear parameters of the first passive gear 54 and the second passive gear 62 are the same. The lead screw 61 passes through the lower part of the rotating disk 51.

[0024] As shown in Figure 1 , Figure 2 shown, the inspection disk 7 is coaxially arranged below the rotating disk 51. Four cameras 71 are evenly arranged around the outer side of the inspection disk 7. The four cameras 71 respectively take images of the shaft wall from four angles, and then the cameras 71 transmit the image data to a processing element (not shown in the figure) for analysis to determine whether the structure of the air shaft has changed. A sensor 72 is arranged above the inspection disk 7. The sensor 72 includes a radar sensor and a millimeter wave sensor to collect data of the air shaft. The sensor 72 also transmits the data to a processing element (not shown in the figure) for analysis to determine whether the structure of the air shaft has changed. Through holes are formed at the positions of the inspection disk 7 corresponding to the vertical rods 52, so that the inspection disk 7 is movably sleeved on the vertical rods 52. A thread corresponding to the lead screw 61 is formed in the middle of the inspection disk 7, so that the lead screw 61 and the inspection disk 7 can perform a threaded drive.

[0025] As shown in Figure 4As shown, the driving device 4 includes: a cylinder 41, a motor 42, a fixed gear 43, and a driving gear 44; the upper end of the cylinder 41 is a fixed end, and the fixed end of the cylinder 41 is fixedly arranged on the side surface of the lifting body 1; the lower end of the cylinder 41 is a telescopic end, and a motor 42 is fixedly arranged at the lower end of the cylinder 41, and the axis direction of the motor 42 is vertically downward; one end of the axis of the motor 42 is fixedly provided with a driving gear 44, and fixed gears 43 are arranged at both the upper end and the lower end of the driving gear 44. The fixed gears 43 are movably sleeved on the motor shaft, and the gear parameters of the fixed gears 43 are the same as those of the first driven gear 54 and the second driven gear 62. One side of the fixed gear 43 is fixedly connected to the fixed end of the motor through a connecting plate. The thickness of the driving gear 44 is twice that of the first driven gear 54, so that when the position of the driving gear 44 is aligned with both the first driven gear 54 and the second driven gear 62, the first driven gear 54 and the second driven gear 62 can be driven to rotate simultaneously; by vertically moving the motor 42 through the cylinder 41, the first driven gear 54 and the second driven gear 62 can be respectively engaged with the driving gear 44 and the fixed gear 43; when the cylinder 41 pushes the motor 42 to the lowest end, at this time the first driven gear 54 is engaged with the driving gear 44, and the second driven gear 62 is engaged with the fixed gear 43 at the uppermost end. At this time, the motor 42 can drive the rotating device 5 to rotate, while the middle shaft body 6 does not rotate, so that the inspection disk 7 can rotate up or rotate down; when the cylinder 41 pushes the motor 42 up to the middle position, at this time both the first driven gear 54 and the second driven gear 62 are engaged with the driving gear 44. At this time, the motor 42 can drive the rotating device 5 and the middle shaft body 6 to rotate, so that the inspection disk 7 can rotate at the same height; when the cylinder 41 pushes the motor 42 to the uppermost end, at this time the first driven gear 54 is engaged with the fixed gear 43 at the lowermost end, and the second driven gear 62 is engaged with the driving gear 44. At this time, the motor 42 can drive the middle shaft body 6 to rotate, while the driving device 5 does not rotate, so that the inspection disk 7 can move vertically up and down;

[0026] Working principle: The cylinder 41 is used to push the motor 42 to three positions: the lowest position, the middle position, and the highest position. When the cylinder 41 pushes the motor 42 to the lowest position, the first driven gear 54 meshes with the driving gear 44, and the second driven gear 62 meshes with the fixed gear 43 at the highest position. At this time, the motor 42 can drive the rotating device 5 to rotate, while the central shaft body 6 does not rotate, enabling the inspection disk 7 to rotate upward or downward; when the cylinder 41 pushes the motor 42 up to the middle position, both the first driven gear 54 and the second driven gear 62 mesh with the driving gear 44. At this time, the motor 42 can drive the rotating device 5 and the central shaft body 6 to rotate, enabling the inspection disk 7 to rotate at the same height; when the cylinder 41 pushes the motor 42 to the highest position, the first driven gear 54 meshes with the fixed gear 43 at the lowest position, and the second driven gear 62 meshes with the driving gear 44. At this time, the motor 42 can drive the central shaft body 6 to rotate, while the driving device 5 does not rotate, enabling the inspection disk 7 to move vertically up and down; when the air shaft inspection device conducts automatic inspection, it only needs to place the motor 42 at the lowest position, enabling the inspection disk 7 to rotate upward or downward to collect wellbore data efficiently. When it is found that the wellbore structure at a certain location is abnormal, the height of the motor 42 can be changed by pushing the cylinder 41, enabling the inspection disk 7 to collect rotation data at the same height and vertical movement data respectively to accurately locate the abnormal structure.
