Description

Technical Field

[0001] The invention relates to blasthole detection equipment, in particular to a panoramic drilling camera suitable for use in inclined holes. Background Art

[0002] In blasting operations, the quality and stability of the blasthole are crucial to ensuring blasting effectiveness and construction safety. Blasthole inspection is a crucial task, aiming to detect hidden dangers or problems within the blasthole, such as cracks and water layers. Currently, the main blasthole inspection equipment is the panoramic borehole camera.

[0003] A panoramic borehole camera generally includes a tripod, a probe, and a winding mechanism for winding the probe. When in use, the probe is placed into the blasthole through the winding mechanism. The probe transmits the image inside the blasthole, and the blasthole can be inspected.

[0004] However, for inclined blastholes, after the probe is placed, it cannot be kept on the center line of the blasthole, but is close to the lower hole wall, resulting in poor imaging quality and the inability to stitch the images later. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that, in view of the deficiency that existing panoramic borehole cameras are not convenient for detecting inclined blastholes, the present invention provides a panoramic borehole camera that is convenient for performing panoramic camera detection on inclined holes.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A panoramic borehole camera suitable for use in inclined holes includes a probe, a support frame, a first winding assembly arranged on the support frame, an adjustment mechanism, a connecting assembly, and a guide assembly. The first winding assembly includes a first winding roller and a first motor. One end of a connecting cable is wound around the first winding roller, and the other end of the cable is fixedly connected to the probe. The first motor is used to drive the first winding roller to rotate. The structural features of the camera are as follows:

[0008] The adjustment mechanism includes a driving module and an adjustment module, the adjustment module includes a first positioning sleeve and at least one group of adjustment components, the first positioning sleeve is detachably mounted on the probe via the connecting assembly, the adjustment component includes at least two oppositely arranged adjustment rods, one end of the adjustment rod is movably connected to the first positioning sleeve, and the other end is used to abut against the inner wall of the blasthole, the driving module drives the adjustment rods of the adjustment assembly to move away from each other, so that the end of each adjustment rod away from the first positioning sleeve abuts against the inner wall of the blasthole;

[0009] The guide assembly includes a guide rope and a guide ring, one end of the guide rope is connected to the adjustment rod, and the other end passes through the guide ring and extends outside the blast hole. The guide ring is fixedly connected to the probe, and the guide ring is located directly above the preset blast hole interference position of the adjustment rod.

[0010] When the present invention is used, the probe is lowered to the bottom of the blasthole through the first winding assembly, and then the adjustment rods are driven away from each other through the driving module, so that the ends of the adjustment rods away from the first positioning sleeve all touch the inner wall of the blasthole. At this time, since the adjustment rods are arranged relative to each other and cooperate with the reaction force of the inner wall of the blasthole, the probe can be located on the center line of the blasthole. Afterwards, the first winding assembly is used to pull out the probe. During this process, since the adjustment rods remain in contact with the inner wall of the blasthole, and the guide rope can be straightened by manpower or machinery, and the positioning effect of the guide ring, the probe can be moved along the center line of the blasthole to achieve panoramic camera detection until the probe moves out of the blasthole. Since the probe always moves along the center line of the blasthole during the use of the present invention, it will not approach the wall below the inclined hole due to gravity. Therefore, the present invention is convenient for detecting inclined blastholes.

[0011] In addition, the present invention can be adapted to blastholes with different apertures by changing the length of the adjustment rod.

One end of the connecting rod is connected to the adjustment rod, and the other end is connected to the sliding sleeve. The adjustment rod is hingedly connected to the first positioning sleeve. In this way, the air pump can be used to inject air into the first air cylinder. Under the action of air pressure, the piston rod of the first air cylinder drives the sliding sleeve to slide, which in turn drives the adjustment rod via the connecting rod to rotate away from the probe until the adjustment rod contacts the inner wall of the blasthole. This drive module utilizes airflow to transmit power and can better adapt to the environment of the blasthole.

[0013] Preferably, the adjustment module also includes a second positioning sleeve, the first positioning sleeve is installed at the lower part of the probe, the second positioning sleeve is installed at the upper part of the probe, the first cylinder is installed on the second positioning sleeve, and the sliding sleeve is installed between the first positioning sleeve and the second positioning sleeve.

After the probe is aligned with the centerline of the blasthole, the guide rope is stretched using the second reel assembly, and the probe is then pulled out of the blasthole using the first reel assembly. The cooperation between the guide ring and the stretched guide rope ensures that the probe remains aligned with the centerline of the blasthole during upward movement.

[0015] Preferably, the rotating shaft of the second winding roller is connected to the output shaft of the second motor.

[0016] Preferably, the second winding roller is provided with a handle for rotating the second winding roller, and the second winding roller is provided with a ratchet pawl structure for limiting the rotation of the second winding roller.

The battery is electrically connected to the electromagnet, which is secured within the annular groove and adsorbed onto the outer wall of the probe. Thus, the first and second positioning sleeves and the probe can be connected and disconnected simply and conveniently by turning the electromagnet on and off.

[0019] Preferably, the battery is installed on the first positioning sleeve, the second positioning sleeve or the support frame.

[0020] Preferably, the driving module includes an air pump, a first cylinder, a sliding sleeve and a second cylinder. The air pump is installed on the support frame.

[0034] Reference Figure 1 - Figure 3 The first embodiment of the panoramic borehole camera suitable for use in inclined holes of the present invention includes a probe 1, a support frame, and a first winding assembly disposed on the support frame. The support frame adopts a quadripod, and the support frame includes a support platform 2 and four support legs 3 rotatably disposed on the support platform 2. The first winding assembly includes a first winding roller 4 and a first motor 5. One end of a fixed cable 6 is wound around the first winding roller 4, and the other end of the cable 6 is fixedly connected to the upper end of the probe 1 after passing through a fixed pulley on the support platform 2. The output shaft of the first motor 5 is connected to the rotating shaft of the first winding roller 4. The first motor 5 drives the first winding roller 4 to rotate to achieve the retraction and extension of the cable 6.

[0035] Embodiment 1 of the panoramic drilling camera suitable for use in inclined holes of the present invention also includes an adjustment mechanism and a connecting assembly. The adjustment mechanism includes an adjustment module and a driving module. The adjustment module includes a first positioning sleeve 7, a second positioning sleeve 26 and at least one set of adjustment assemblies. The first positioning sleeve 7 is detachably mounted on the lower part of the probe 1 through a connecting assembly, and the second positioning sleeve 26 is detachably mounted on the upper part of the probe 1 through a connecting assembly. The adjustment assembly is provided in two groups, and each group of adjustment assemblies includes two adjustment rods 8 arranged opposite to each other. The four adjustment rods 8 are equidistantly hinged on the peripheral wall of the first positioning sleeve 7, and one end of the adjustment rod 8 is hinged to the first positioning sleeve 7, and the other end is used to contact the inner wall of the blast hole.

[0036] Under the action of the driving module, the adjusting rods 8 can rotate synchronously away from each other until the end of the adjusting rod 8 away from the first positioning sleeve hits the inner wall of the blast hole.

[0037] The drive module includes an air pump 10, a first air cylinder 11, a sliding sleeve 9, and a connecting rod 14. The air pump 10 is fixedly mounted on the support platform 2. The air outlet of the air pump 10 is connected to one end of a hose 13, the other end of which is connected to the rodless cavity of the first air cylinder 11. The sliding sleeve 9 is positioned between the first positioning sleeve 7 and the second positioning sleeve 26 and can slide along the length of the probe 1. The second positioning sleeve 26 is fixedly connected to the first air cylinder 11, and the piston rod 12 of the first cylinder 11 is connected to the sliding sleeve 9. The sliding sleeve 9 is slidably mounted on the probe 1. One end of the connecting rod 14 is hinged to the middle of the adjustment rod 8, and the other end is hinged to the sliding sleeve 9. When the air pump 10 injects air into the first air cylinder 11, the air pressure causes the piston rod 12 of the first cylinder 11 to drive the sliding sleeve 9 downward. This, in turn, drives the adjustment rod 8 to rotate away from the probe 1 through the connecting rod 14 until the end of the adjustment rod 8 away from the first positioning sleeve contacts the inner wall of the blasthole.

[0038] The first embodiment of the panoramic borehole camera suitable for use in inclined holes of the present invention further includes a guide assembly, which includes a second winding assembly, a guide rope 15, and a guide ring 16. In this embodiment, the second winding assembly is mounted on each of the four support legs 22. The second winding assembly includes a second motor 17 and a second winding roller 18. The second motor 17 is fixedly connected to the support legs 22, and the output shaft of the second motor 17 is fixedly connected to the rotating shaft of the second winding roller 18. Four guide ropes 15 are also provided. The lower end of the guide rope 15 is fixedly connected to the end of the adjustment rod 8 away from the first positioning sleeve 7, and the other end is wrapped and fixedly connected to the second winding roller 18. The upper end of the probe 1 is fixedly connected to four connecting rods 25. The ends of the four connecting rods 25 away from the probe are fixedly connected to the guide rings 16. The four guide rings 16 are respectively mounted on the four guide ropes 15, and each guide ring 16 is located directly above the preset blasthole interference position of the adjustment rod 8. After the probe 1 is adjusted to the center line of the blast hole, the second winding roller 18 is used to straighten the guide rope 15, and then the first winding assembly is used to pull the probe 1 out of the blast hole. With the cooperation of the guide ring 16 and the straightened guide rope 15, the probe 1 can always be located on the center line of the blast hole during the upward movement.

[0039] In some embodiments, the second winding assembly can also use a handle to drive the second winding roller 18 to rotate, and a ratchet pawl structure is correspondingly provided to limit the rotation of the second winding roller 18 so that the guide rope 15 can be in a straightened state.

[0040] In this embodiment, the connecting assembly includes an electromagnet 19, and an annular groove 20 is respectively provided on the inner wall of the first positioning sleeve 7 and the second positioning sleeve 26. The electromagnet 19 is annular and can be adaptably fixed in the annular groove 20. The electromagnet 19 is used to adsorb the outer wall of the probe 1.

[0041] In this embodiment, batteries are installed on the first positioning sleeve 7 and the second positioning sleeve 26 to power the electromagnet 19. At the same time, the electromagnet 19 can be controlled to open and close by remote control or other remote means. In other embodiments, the battery can also be set on the support platform 2 and the electromagnet 19 can be powered by wires.

[0042] To use the panoramic borehole camera of the present invention, the probe 1 is lowered to the bottom of the blasthole. Then, air is injected into the first cylinder 11 using the air pump 10. The air pressure within the first cylinder 11 drives the piston rod 12 to move, thereby driving the sliding sleeve 9 along the length of the probe 1. Simultaneously, the sliding sleeve 9 causes the connecting rod 14 and the adjustment rod 8 to rotate accordingly. The two adjustment rods 8 rotate synchronously away from each other until the ends of the adjustment rods 8, away from the first positioning sleeve, contact the inner wall of the blasthole. This allows the probe 1 to be aligned with the centerline of the blasthole under the reaction force provided by the inner wall. The second winding roller 18 is then controlled to rotate, keeping the guide rope 15 in a straight position. Finally, the first winding assembly is used to pull the probe 1 out of the blasthole. During this process, the guide ring 16, in conjunction with the guide rope 15, ensures that the probe 1 remains aligned with the centerline of the blasthole, facilitating the inspection of tilted blastholes.

[0043] Reference Figure 4 The adjustment rod 8 can also be slidably inserted into the first positioning sleeve 7 in a direction perpendicular to the length of the probe 1. The first positioning sleeve 7 has multiple slots 21 for the adjustment rod 8 to slide into. The first positioning sleeve 7 is fixedly connected to the second air cylinder 24. Accordingly, there are four second air cylinders 24. One end of the piston rod 23 of the second air cylinder 24 is located outside the second air cylinder 24 and on the movement path of the sliding sleeve 9. The four slots 21 are respectively connected to the rodless chambers of the four second air cylinders 24. The rodless chambers of the second air cylinders 24 are fixedly connected to the spring 22. When in use, the probe 1 is lowered to the bottom of the blasthole. The air pump 10 is then used to inject air into the first air cylinder 11, driving the piston rod 12 of the first air cylinder 11 to move, thereby driving the sliding sleeve 9 to move. The sliding sleeve 9 slides, pushing the piston rod 23 of the second air cylinder 24 to compress the spring 22 and move, thereby injecting air into the slots 21. Under the action of the air pressure, the adjustment rod 8 moves toward the inner wall of the blasthole and contacts the inner wall of the blasthole.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make many possible changes and modifications to the technical solution of the present invention using the technical content disclosed above, or modify it into an equivalent embodiment with equivalent changes.
