Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of coal mine drilling inspection equipment, specifically relating to a self-moving mine inspection probe. Background Technology
[0002] For coal mine production, underground geological conditions are very important. Among the methods for detecting and observing cracks in the roof strata, ground electrical surveying and drilling are relatively expensive, and most measurement methods cannot directly observe the condition of the roadway roof. Therefore, using a peephole to observe the condition of the roadway roof is still one of the most important and convenient methods.
[0003] However, in the actual use of the viewing device, the following problems still exist: due to the difference in the diameter of the drill hole, it is impossible to steadily advance the viewing device probe during the viewing process, which makes the viewing device probe easy to collide with the hole wall. This not only easily damages the probe, but also makes the viewing image quality poor, affecting the accuracy of the viewing operation and reducing the efficiency of the viewing operation.
[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content
[0005] The purpose of this invention is to provide a self-moving mining observation probe to at least solve the aforementioned problems existing in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A self-moving mine inspection probe, the probe comprising:
[0008] The probe housing includes a frustum-shaped front portion and a cylindrical rear portion; a self-moving mechanism, wherein at least two self-moving mechanisms are provided at intervals in the rear portion of the probe housing.
[0009] The self-moving mechanism includes a flipping rubber ring and a driving mechanism. The middle and rear part of the probe housing is provided with an circumferential groove corresponding to the self-moving mechanism. The flipping rubber ring is sleeved in the circumferential groove of the probe housing, and the inner ring of the flipping rubber ring contacts the probe housing, while the outer ring of the flipping rubber ring contacts the hole wall of the drilled hole. The driving mechanism is used to drive the flipping rubber ring to flip, so that the flipping rubber ring drives the probe housing to move in the drilled hole.
[0010] In the self-moving mining inspection probe described above, preferably, the driving mechanism includes a servo motor, which is disposed inside the probe housing. The output end of the servo motor is connected to a worm gear, and the central axis of the worm gear extends along the central axis of the probe.
[0011] In the self-moving mining sighting probe described above, preferably, the driving mechanism further includes a worm gear, which meshes with a worm for transmission, and the central axis of the worm gear is perpendicular to the central axis of the probe.
[0012] In the self-moving mining inspection probe described above, preferably, a rotating shaft is rotatably arranged inside the probe housing, and the worm gear is mounted on the rotating shaft.
[0013] Preferably, in the self-moving mining inspection probe described above, a clearance hole is provided on the side of the circumferential groove away from the worm gear, and a portion of the worm wheel protrudes through the clearance hole.
[0014] In the self-moving mining inspection probe described above, preferably, the rotating rubber ring is provided with an engagement part corresponding to the position of the avoidance hole, and the engagement part is a worm gear groove provided on the rotating rubber ring;
[0015] The portion of the worm gear extending out of the clearance hole engages with the meshing portion of the flipping rubber ring for transmission.
[0016] In the self-moving mining inspection probe described above, preferably, a distance sensor is provided on the front end face of the front part of the probe housing, and the distance sensor is used to detect the distance between the front end face of the probe housing and the bottom of the borehole.
[0017] As described above, in the preferred embodiment, a viewing camera is disposed at the center of the front end face of the front part of the probe housing, and a power supply and signal line are connected to the probe rod connection part at the rear end face of the middle and rear part of the probe housing.
[0018] As described above, the self-moving mining peephole probe preferably has an illumination lamp on the front end face of the front part of the probe housing, and the illumination lamp is a ring of illumination lamp beads located around the periphery of the peephole camera.
[0019] Beneficial effects:
[0020] In this peephole probe, a suitable size of rotating rubber ring can be selected according to the diameter of the borehole, so that the peephole probe can be applied to boreholes of different diameters.
[0021] By setting a worm gear groove on the rotating rubber ring, the worm gear groove can mesh with the worm gear for transmission. Due to the elasticity of the rotating rubber ring, under the transmission action of the rotating worm gear, the rotating rubber ring rotates from the inner ring to the outer ring, thereby driving the peep sight probe to move in a creeping motion. This ensures that the peep sight probe can move more stably and reliably in the borehole, and can avoid the peep sight probe from colliding with the borehole wall. It also helps to improve the accuracy and efficiency of the peep sighting operation.
[0022] The distance sensor detects the distance between the front end of the probe housing and the bottom of the borehole in real time. When the probe reaches the set distance from the bottom of the hole, the servo motor is controlled to stop moving in time to avoid the probe from continuing to move forward and colliding with the bottom of the hole.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0032] According to specific embodiments of this utility model, such as Figure 1-3 As shown, this utility model provides a self-moving mine inspection probe, the probe comprising:
[0033] The probe housing 1 includes a frustum-shaped front part and a cylindrical middle and rear part; the self-moving mechanism 3 is provided at least two sets of self-moving mechanisms 3 at intervals in the middle and rear part of the probe housing 1.
[0034] The self-moving mechanism 3 includes a flipping rubber ring 35 and a driving mechanism. A circumferential groove is provided in the middle and rear part of the probe housing 1 corresponding to the part of the self-moving mechanism 3. The flipping rubber ring 35 is sleeved in the circumferential groove of the probe housing 1, and the inner ring of the flipping rubber ring 35 contacts the probe housing 1, while the outer ring of the flipping rubber ring 35 contacts the hole wall of the drilled hole. The driving mechanism is used to drive the flipping rubber ring 35 to flip, so that the flipping rubber ring 35 drives the probe housing 1 to move in the drilled hole.
[0035] In this peephole probe, a suitable size of rotating rubber ring 35 can be selected according to the diameter of the borehole to ensure that the rotating rubber ring 35 effectively contacts the borehole wall, so that the peephole probe can be applied to boreholes of different diameters.
[0036] The rotating rubber ring 35 is rotated by the drive mechanism. As the rotating rubber ring 35 contacts the borehole wall, the friction between the rotating rubber ring 35 and the borehole wall causes the rotating rubber ring 35 to rotate and move within the borehole, thereby moving the probe housing 1 within the borehole. Since the rotating rubber ring 35 is located between the probe housing 1 and the borehole wall, it ensures that the peephole probe will not collide with the borehole wall during movement. This not only avoids collisions between the peephole probe and the borehole wall but also ensures that the peephole probe can move more stably and reliably within the borehole, which is beneficial for improving the accuracy and efficiency of peephole operations.
[0037] In this embodiment, since the front part of the probe housing 1 is provided with a frustum shape, the diameter of the front part of the probe housing 1 gradually decreases, that is, the diameter at the front end where the spy camera 2 is set is the smallest; then when dust, mud and water fall from the borehole wall, the frustum-shaped front part of the probe provides a space to avoid these debris, so that these debris will not directly accumulate at the front end of the probe, thereby improving the efficiency of the spying operation.
[0038] The drive mechanism includes a servo motor 31, which is located inside the probe housing 1. The output end of the servo motor 31 is connected to a worm gear 32, and the central axis of the worm gear 32 extends along the central axis of the probe.
[0039] In one embodiment of this application, the servo motor 31 is a micro servo motor 31, so that the micro servo motor 31 can be set inside the probe housing 1 without occupying too much space inside the probe housing 1; a worm gear 32 is connected to the output end of the servo motor 31, and the transmission direction is changed through the worm gear 32.
[0040] The drive mechanism also includes a worm gear 33, which meshes with the worm 32 for transmission, and the central axis of the worm gear 33 is perpendicular to the central axis of the probe.
[0041] A rotating shaft 34 is rotatably disposed inside the probe housing 1, and a worm gear 33 is mounted on the rotating shaft 34. In one embodiment of this application, under the transmission action of the worm 32, the worm gear 33 rotates synchronously with the rotating shaft 34; and the rotation of the worm gear 33 extends the driving action to the outer ring position of the probe housing 1, so as to better drive the flipping rubber ring 35 to flip.
[0042] An clearance hole is provided on the side of the circumferential groove away from the worm 32, and a portion of the worm wheel 33 protrudes through the clearance hole. In one embodiment of this application, a clearance hole is provided in the circumferential groove of the probe housing 1 so that a portion of the worm wheel 33 can extend out of the clearance hole, thereby facilitating the worm wheel 33 to drive the flipping rubber ring 35.
[0043] The rotating rubber ring 35 has a meshing part corresponding to the clearance hole, which is a worm gear groove on the rotating rubber ring 35. The part of the worm gear 33 extending out of the clearance hole meshes with the meshing part of the rotating rubber ring 35 for transmission. In one embodiment of this application, by providing a worm gear groove on the rotating rubber ring 35, the worm gear groove can mesh with the worm gear 33 for transmission. Since the rotating rubber ring 35 has a certain elasticity, under the transmission action of rotating worm gear 33, the rotating rubber ring 35 rotates from the inner ring to the outer ring, thereby driving the peephole probe to move peristally, thus ensuring that the peephole probe can move stably in the borehole.
[0044] A distance sensor 21 is provided on the front end face of the probe housing 1. The distance sensor 21 is used to detect the distance between the front end face of the probe housing 1 and the bottom of the borehole. In one embodiment of this application, the distance sensor 21 detects the distance between the front end face of the probe housing 1 and the bottom of the borehole in real time. When the distance between the probe and the bottom of the hole reaches a set value, the servo motor 31 is controlled to stop moving in time to avoid the probe of the peephole from continuing to move forward and colliding with the bottom of the hole.
[0045] A viewing camera 2 is provided at the center of the front end face of the probe housing 1, and a power supply and signal line 5 and a probe rod connection part 4 are connected to the rear end face of the middle and rear part of the probe housing 1.
[0046] In this embodiment, the power and signal line 5 integrates a power line and a signal transmission line. The power and signal line 5 is used not only to supply power to the lighting lamp and the servo motor 31, but also to transmit the video signal from the spy camera 2 and the monitoring signal from the distance sensor 21 to the processing end in real time.
[0047] The probe rod connecting part 4 is provided with a threaded part, and the end of the probe rod is connected to the probe rod connecting part 4 by the thread, so that the probe of the peephole can be moved by controlling the probe rod.
[0048] A light is provided on the front end face of the probe housing 1. The light is a ring of LED beads 22 located around the periphery of the peep camera 2. In one embodiment of this application, a ring of LED beads 22 is provided around the periphery of the peep camera 2 to provide illumination for the peep camera 2 and facilitate the peeping operation of the peep camera 2.
[0049] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
