Description

Technical Field

[0001] This utility model relates to the field of borehole inspection technology, and in particular to an adaptive borehole diameter guiding device for a mining borehole inspection instrument. Background Technology

[0002] A borehole inspection instrument is a high-tech device used to observe and inspect the interior of a borehole. It is widely used in geological exploration, engineering safety monitoring, and other fields, and can clearly and intuitively display information such as rock strata structure and fracture development within the borehole.

[0003] When using a borehole inspection instrument for borehole inspection, the instrument is usually placed directly into the borehole and then slowly lowered. However, this method of operation makes it easy for the borehole inspection instrument to collide with the borehole wall, causing wear and tear on its surface. If the borehole wall collapses, sharp edges will appear at the collapse points. The borehole inspection instrument is prone to hitting these sharp edges during movement, damaging the instrument.

[0004] Therefore, it is necessary to provide an adaptive aperture guidance device for a mining borehole inspection instrument to solve the above-mentioned technical problems. Utility Model Content

[0005] In response to the above situation and to overcome the defects of the existing technology, this utility model provides an adaptive borehole diameter guiding device for a mining borehole inspection instrument that can adapt to boreholes of different diameters, ensuring that the borehole inspection instrument can be used smoothly in boreholes of various sizes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Multiple fixing grooves are provided on the outer wall of the connecting block, and the connecting plates are fixed inside the fixing grooves by bolts.

[0010] Preferably, a rubber pad is installed on the inner arc of the arc-shaped card plate.

[0011] Preferably, the two arc-shaped plates are fixed by two screws.

[0012] Preferably, a cone is fixed to one end of the mounting tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model can adapt to holes of different diameters by gathering and dispersing the rollers, ensuring that the drilling inspection instrument can be used smoothly in holes of various sizes.

[0015] (2) The spring design enables the rollers to automatically disperse when they encounter a collapse, maintaining contact with the borehole wall, thereby avoiding friction and collision between the outer wall of the borehole inspection instrument and the borehole wall, and improving the stability and accuracy of the inspection process.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0027] Example 1

[0028] like Figure 1-6As shown, the adaptive borehole diameter guiding device for a mining borehole inspection instrument provided by this utility model includes: a borehole inspection instrument 1, a connecting block 2 installed at one end of the borehole inspection instrument, an installation tube 3 fixedly installed on the side of the connecting block 2 away from the borehole inspection instrument 1, at least three limiting elongated holes 4 opened on the installation tube 3, a rotating rod 5 hinged in the limiting elongated holes 4, a roller 6 rotatably installed at one end of the rotating rod 5, a support rod 8 rotatably installed on the rotating rod 5, and a moving rod 9 slidably installed inside the installation tube 3. Multiple of the above-mentioned... All support rods 8 are hinged to the movable rod 9. Moving the movable rod 9 simultaneously moves multiple support rods 8, which in turn moves multiple rotating rods 5, causing the multiple rollers 6 to converge or disperse. During use, the multiple rollers 6 contact the inside of the drill hole. As the multiple rollers 6 converge or disperse, this device can adapt to drill holes of different diameters. The connecting block 2 has an internal mounting cavity 10, within which a sliding plate 11 is slidably mounted. One end of the movable rod 9 extends into the mounting cavity 10 and is connected to the sliding plate. 11. Fixed connection. A spring 12 is provided inside the mounting cavity 10. The spring 12 contacts the sliding plate 11. In use, multiple rotating rods 5 are pressed simultaneously to bring multiple rollers 6 together. During the pressing process, the multiple rotating rods 5 push the moving rod 9 into the mounting cavity 10 through the support rod 8. The movement of the moving rod 9 drives the sliding plate 11 to move and compress the spring 12, causing the spring 12 to contract. Then, the mounting tube 3 and multiple rollers 6 are inserted into the drill hole. When all multiple rollers 6 have entered the drill hole, the spring 12 will release. The spring 12 pushes the slide plate 11 towards the mounting tube 3, which in turn moves the moving rod 9, causing the multiple rollers 6 to disperse until they contact the borehole wall. During the drilling process, even if a collapse occurs in the borehole, the multiple rollers 6 will automatically disperse under the action of the spring 12 to adapt to the diameter of the borehole, thus ensuring that the borehole inspection instrument 1 moves along the center of the borehole and avoiding friction and collision between the borehole wall and the outer wall of the borehole inspection instrument. Similarly, this device can also adapt to boreholes of different diameters within a certain range.

[0029] Example 2

[0030] like Figure 3 As shown, the rotating rod 5 has a long groove 7, and one end of the support rod 8 is hinged in the long groove 7. When multiple rotating rods 5 approach each other, the support rod 8 restricts the rotation of the rotating rods 5. Once the rotating rod 5 contacts the support rod 8 during rotation, the support rod 8 will prevent the rotating rod 5 from continuing to rotate (excluding reverse rotation). At this time, the multiple rollers 6 cannot be adjusted. The long groove 7 can extend the contact distance between the rotating rod 5 and the support rod 8, thereby allowing the multiple rollers 6 to have a wider range of adjustment and improving the adaptability of this device.

[0031] Example 3

[0032] like Figure 1 , 5 As shown in Figure 6, a groove 13 is provided on one side of the connecting block 2, and the drilling inspection instrument 1 is inserted into the groove 13. Two arc-shaped clamping plates 14 are provided on one side of the connecting block 2. The two arc-shaped clamping plates 14 are combined to fix the drilling inspection instrument 1. Two connecting plates 15 are fixed on one side of the arc-shaped clamping plates 14. Multiple fixing grooves 16 are provided on the outer wall of the connecting block 2. The connecting plates 15 are fixed inside the fixing grooves 16 by bolts. Under the action of the fixing grooves 16 and the connecting plates 15, the arc-shaped clamping plates 14 and the connecting block 2 are integrated, thereby enabling the drilling inspection instrument 1 to be connected to the connecting block 2.

[0033] Furthermore, a rubber pad 17 is installed on the inner arc of the arc-shaped clamping plate 14. When the two arc-shaped clamping plates 14 are used to fix the borehole inspection instrument, the rubber pad 17 contacts the borehole inspection instrument 1, thereby avoiding damage to the borehole inspection instrument.

[0034] Furthermore, the two arc-shaped clamping plates 14 are fixed by two screws 18, and the connection between the arc-shaped clamping plates 14 and the borehole inspection instrument 1 is more secure under the fixation of the two screws 18.

[0035] Example 4

[0036] like Figure 1 As shown, one end of the mounting tube 3 is fixed with a cone 19. When in use, the cone 19 can push open foreign objects in the drill hole, which is more conducive to the advancement of the components behind it in the drill hole.

[0037] Working principle: In use, first press multiple rotating rods 5 simultaneously to bring multiple rollers 6 together. During the pressing process, the multiple rotating rods 5 push the moving rod 9 into the mounting cavity 10 through the support rod 8. The movement of the moving rod 9 drives the sliding plate 11 to move and compress the spring 12, causing the spring 12 to contract. Then, insert the mounting tube 3 and multiple rollers 6 into the drill hole. When multiple rollers 6 have entered the drill hole, the spring 12 will release its elasticity, pushing the sliding plate 11 towards the mounting tube 3, which in turn causes the moving rod 9 to move, dispersing the multiple rollers 6 until the rollers 6 contact the drill hole wall. At this time, the drilling inspection instrument 1 can be pushed into the drill hole.
