In existing technologies, newly built vertical shafts must be inspected and measured to ensure their quality and improve mine safety.

[0029] according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the present embodiment provides a safety detection and measurement device for mine construction, comprising a square-designed mounting plate 1 and a detection controller 2 engaged with the top right side of the mounting plate 1. An engaging groove is provided on the top right side of the mounting plate 1 for installation of the detection controller 2. The user wirelessly starts each measuring instrument through the detection controller 2, and the measurement data is displayed in real time on the display screen on the detection controller 2. Receiving grooves 3 are provided on the four outer walls on the front, back, left and right sides of the mounting plate 1. A telescopic support member 4 with a telescopic adjustment function is hingedly connected to the inside of each receiving groove 3 through a hinge. The four groups of telescopic supports 4 provide support for the mounting plate 1 at the shaft mouth to realize the installation of the shaft mouth of the device. A first receiving limit mechanism is provided on the four outer walls on the front, back, left and right sides of the mounting plate 1, and the first receiving limit mechanism is adapted to the telescopic support member 4 for limiting and blocking the telescopic support member 4 to prevent it from falling out of the receiving groove 3.

A take-up motor 5 fixed to the mounting plate 1 is provided on the left side of the winding roller 6, and the winding roller 6 is driven to rotate by the take-up motor 5. A lifting rope 7 is wound around the winding roller 6, and the winding roller 6 is driven by the take-up motor 5 to rotate forward or reverse to realize the unwinding or rewinding of the lifting rope 7. A lifting block is fixed to the bottom end of the lifting rope 7, and the lifting block and the fixed plate 8 are fixedly connected by four groups of lifting cables distributed symmetrically to realize the lifting of the fixed plate 8 at the bottom end of the lifting rope 7. A second storage limiting mechanism is provided on both sides of the bottom end of the mounting plate 1, and the second storage limiting mechanism is adapted to the fixed plate 8 and is used to limit and fix the fixed plate 8 to the bottom end of the fixed plate 8;

[0031] Three groups of push rods 9 distributed in an annular and equidistant manner are slidingly passed through the outer wall of the fixed plate 8, and the push rods 9 are driven to move by the telescopic driving mechanism, and can extend from the inside of the fixed plate 8 or retract into the fixed plate 8. The end of the push rod 9 away from the fixed plate 8 is fixed with an in-well positioning cone 36 by bolts. The push rod 9 and the in-well positioning cone 36 together constitute the supporting structure of the fixed plate 8 in the vertical shaft to ensure the stability of the fixed plate 8. A rotating motor 10 is fixed to the top of the fixed plate 8 by bolts, and a rotating plate 11 is rotatably connected to the bottom end of the fixed plate 8, and the rotating plate 11 is driven to rotate by the rotating motor 10 to realize safety detection and measurement work in different directions. An ultrasonic crack detector 12 and a gas detector 13 are respectively provided on the left and right sides of the bottom end of the rotating plate 11, and the ultrasonic crack detector 12 and the gas detector 13 are installed at the bottom end of the rotating plate 11 by a detachable mounting mechanism and can rotate with the rotating plate 11. The ultrasonic crack detector 12 and the gas detector 13 are both wirelessly connected to the detection controller 2 via Bluetooth to provide real-time feedback of measurement data to the detection controller 2 for user understanding.

[0032] The detachable mounting mechanism includes a top plate 14 and a bottom plate 15, wherein the top plate 14 is fixed to the bottom end of the rotating plate 11 by bolts, and the bottom plate 15 is located below the rotating plate 11. The top end of the bottom plate 15 is rotatably connected to a threaded tube 16 through a bearing, and a threaded rod 17 is threadedly connected to the inner side of the threaded tube 16. The top end of the threaded rod 17 is fixed to the bottom end of the top plate 14 by screws, and a limiting tube 18 symmetrically distributed front and back is fixed by screws on the side of the top end of the bottom plate 15 away from the threaded tube 16 (the symmetrical distribution design avoids affecting the normal measurement work of the ultrasonic crack detector 12 and the gas detector 13). The inner side of the limiting tube 18 is slidably connected to the limiting rod 19, and the top end of the limiting rod 19 is screwed The thread is fixed to the bottom end of the top plate 14, and anti-slip rubber pads are fixed on the opposite sides of the top plate 14 and the bottom plate 15, which play an anti-slip role for the installed ultrasonic crack detector 12 and gas detector 13, making the ultrasonic crack detector 12 and the gas detector 13 more stable during installation. The threaded tube 16 is rotated to move on the threaded rod 17. During the movement of the threaded tube 16, the bottom plate 15 is driven to move synchronously (the cooperation of the limit tube 18 and the limit rod 19 plays a limiting role). When the bottom plate 15 moves upward, it can cooperate with the top plate 14 to clamp and limit the ultrasonic crack detector 12 or the gas detector 13. Otherwise, the clamping limit is released, thereby realizing convenient detachable installation.

[0033] A rotating shaft 20 is fixed to the top of the rotating plate 11 by bolts. The top of the rotating shaft 20 passes through the fixed plate 8 through a bearing and is fixed to the output end of the rotating motor 10. An auxiliary hanging mechanism is provided between the fixed plate 8 and the rotating plate 11 to provide auxiliary support for the rotating plate 11 to prevent the output shaft of the rotating motor 10 from being subjected to excessive force. The rotating shaft 20 is driven to rotate by the rotating motor 10, and the rotating shaft 20 then drives the rotating plate 11 to rotate synchronously.

[0034] The auxiliary lifting mechanism includes an inner ring plate 21 and an outer ring plate 22. The cross-sections of the inner ring plate 21 and the outer ring plate 22 are both L-shaped, wherein the inner ring plate 21 is fixed to the bottom end of the fixed plate 8 by bolts and the bottom is bent outward, and the outer ring plate 22 is fixed to the top of the rotating plate 11 by bolts and the top is bent inward. The bent portion of the inner ring plate 21 is fixed with support balls 23 distributed in a circular shape and at equal intervals, and the top of the support balls 23 is in contact with the bent portion of the outer ring plate 22. The inner ring plate 21 provides auxiliary support to the outer ring plate 22, thereby reducing the load on the output shaft of the rotating motor 10.

[0035] The telescopic drive mechanism includes a servo motor 24, a screw rod 25 and a threaded plate 26. The screw rod 25 is rotatably connected to the cavity inside the fixed plate 8 through a bearing and is driven to rotate by the servo motor 24. The threaded plate 26 is located in the cavity inside the fixed plate 8 and is threadedly sleeved on the screw rod 25. The end of the push rod 9 away from the positioning cone 36 in the well slides through the interior of the fixed plate 8 and is fixedly connected to the threaded plate 26. The screw rod 25 is driven to rotate by the servo motor 24, so that the threaded plate 26 threadedly sleeved on the screw rod 25 is displaced along the screw rod 25 in the cavity inside the fixed plate 8. During the displacement of the threaded plate 26, the positioning cone 36 in the well is driven to displace synchronously through the push rod 9.

[0036] The second storage limit mechanism includes an L-shaped hanging plate 27 and a threaded column 28, wherein the L-shaped hanging plate 27 is rotatably connected to the bottom end of the mounting plate 1 through a bearing, the threaded column 28 threads through the bottom end of the L-shaped hanging plate 27, the bottom end of the threaded column 28 is fixed with a knob 29 by a screw, and the top end of the threaded column 28 is connected to an anti-slip positioning block 30. When the fixed plate 8 is lifted to the top, the L-shaped hanging plate 27 is rotated so that the anti-slip positioning block 30 is located below the fixed plate 8. At this time, the threaded column 28 is driven to rotate upward by rotating the knob 29 until the anti-slip positioning block 30 is driven to press against the bottom end of the fixed plate 8, thereby realizing the storage limit between the fixed plate 8 and the mounting plate 1.

[0037] The first storage limit mechanism includes a spring cavity 31 and a slide column 32, wherein the spring cavity 31 is provided with four groups and respectively opened at the four corners of the mounting plate 1, and the four groups of slide columns 32 are respectively fixed inside the spring cavity 31, and a spring plate 33 is slidingly sleeved on the slide column 32 to penetrate to the outside of the mounting plate 1, and a through groove is opened on the outer wall of the mounting plate 1 to communicate with the spring cavity 31 for the spring plate 33 to slide, and a limiting spring 34 is connected between the spring plate 33 and the inner wall of the spring cavity 31, and the limiting spring 34 is sleeved on the outer periphery of the slide column 32, and a limiting baffle 35 is fixed on the side of the spring plate 33 close to the receiving groove 3, and the limiting spring 34 provides an elastic ejection force for the spring plate 33, and ejects the limiting baffle 35 toward the receiving groove 3, thereby playing a limiting and blocking role for the telescopic support member 4 in the receiving groove 3.

[0038] The telescopic support member 4 includes a telescopic rod 401 and a telescopic tube 402, wherein the telescopic rod 401 is hinged to the inner wall of the storage groove 3 through a hinge, and the telescopic tube 402 is slidably sleeved on the outside of the telescopic rod 401, and a limit block 403 is fixed to the end of the telescopic tube 402 away from the mounting plate 1. When the telescopic support member 4 is supported on the wellhead of the vertical shaft, the limit block 403 is stuck on the edge of the wellhead, playing a certain limiting role. A positioning bolt 404 is threaded through the telescopic tube 402, and positioning holes 405 distributed at equal intervals are opened on the top of the telescopic rod 401, and the positioning holes 405 are adapted to the positioning bolts 404. By screwing the positioning bolts 404 into the positioning holes 405, the adjusted positioning and fixation of the telescopic rod 401 and the telescopic tube 402 are achieved.

[0039] When it is necessary to carry out safety inspection and measurement inside the newly built vertical shaft during the mine construction process, the four sets of telescopic support members 4 are first unfolded from the four sides of the mounting plate 1, and the four sets of telescopic support members 4 are respectively telescoped and adjusted to appropriate lengths according to the size of the vertical shaft opening to be inspected. Then, the safety inspection and measurement device for the mine construction well is placed at the vertical shaft opening, and the mounting plate 1 is supported and placed at the vertical shaft opening by using the four sets of telescopic support members 4. The winding motor 5 is then started to drive the winding roller 6 to rotate and unwind the lifting rope 7 wound thereon, driving the fixed plate 8 and the rotating plate 11 connected to the bottom end of the lifting rope 7 to fall into the vertical shaft until the ultrasonic crack detector 12 and the gas detector 13 are lowered to the position to be inspected in the vertical shaft, and then the telescopic driving mechanism is used to drive the three sets of push rods 9 on the inner side of the fixed plate 8 to be pushed outward until the three sets of wells are driven. The inner positioning cone 36 contacts the inner wall of the shaft to realize the self-positioning of the fixed plate 8, the rotating plate 11 and the ultrasonic crack detector 12 at its bottom and the gas detector 13 in the shaft. Then the gas detector 13 is turned on to detect the air condition in the shaft. The gas detector 13 measures the spectral properties of the air by infrared light. The type of gas can be identified by measuring the absorption spectrum, and the concentration of the measured gas can be determined by measuring the absorption intensity. The measurement results are wirelessly sent to the detection controller 2 for display. At the same time, the ultrasonic crack detector 12 is turned on to measure the shaft wall and the measurement results are wirelessly sent to the detection controller 2 for display. During the measurement, the reflected wave of the ultrasonic wave is converted into energy, and then the ripples are displayed by processing, thereby determining whether there are cracks in the shaft wall. This can be used to detect the safety of the shaft.

[0040] When the safety inspection and measurement device for mine construction needs to be folded and stored after the safety inspection, the winding motor 5 is first started to drive the winding roller 6 to rotate in the opposite direction and reel in the hanging rope 7 wound thereon, so as to drive the fixed plate 8 to rise to the top, and then the second storage limit mechanism is used to limit and fix the fixed plate 8 at the bottom end of the fixed plate 8, thus completing the preliminary storage. Then, the four sets of telescopic support members 4 are telescopically adjusted to the shortest, folded and stored in the storage slot 3 along the hinge, and then the first storage limit mechanism is used to limit and block the telescopic support member 4 to prevent it from sliding out of the storage slot 3, thus completing the entire folding and storage work, reducing the volume of the device to a certain extent, making it convenient for movement, transfer and storage.

[0041] When the ultrasonic crack detector 12 and the gas detector 13 need to be disassembled for maintenance, inspection or replacement, the fixed limit of the ultrasonic crack detector 12 and the gas detector 13 by the detachable mounting mechanism is released, and the ultrasonic crack detector 12 and the gas detector 13 can be directly removed to complete convenient disassembly. When installing, the ultrasonic crack detector 12 and the gas detector 13 can be fixed and limited by the detachable mounting mechanism.
