Description

Technical Field

[0001] The invention relates to the technical field of auxiliary devices for installing peephole devices, and in particular to a probe pushing device for a drilling peephole device. Background Art

[0002] In many engineering fields such as the coal industry, the borehole peep method is an important means of monitoring the stratum structure, surrounding rock conditions and obtaining data inside the hole. By setting the angle to drill the hole, and then inserting the borehole peep probe into it to take pictures or videos, intuitive and reliable image data is formed, which is not restricted by the time and space of mining.

[0003] However, the current borehole peeping operation has significant defects in the link of pushing the peeping instrument; on the one hand, it mainly relies on manual operation, and it is difficult for the operator to accurately control the advancement speed of the peeping instrument. At the same time, it is difficult to ensure the stability of the peeping effect in actual operation. The traditional cable-type probe is prone to swinging during the insertion process and hitting the borehole wall, causing damage, that is, the probe shaking, which will seriously interfere with the imaging effect, resulting in blurred and deformed images of the inside of the borehole, greatly reducing the accuracy of the judgment of the internal situation of the borehole; on the other hand, there is currently no effective pushing device to deal with some oblique boreholes, which will cause the probe to stick to the borehole wall due to gravity, resulting in a blind spot in the probe, and friction with the borehole wall during the advancement process, which is easy to damage the equipment.

[0004] To sum up, the current application of the cable front-end probe of the borehole peep instrument in the borehole is inconvenient. It is necessary to consider avoiding damage to the probe during the advancement process and to be able to move stably in the borehole so as to record more accurate information inside the borehole. In view of this, we propose a borehole peep instrument probe pushing device. Summary of the Invention

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0019] Please refer to Figures 1-8 The technical solutions are described in detail by the following embodiments of the present application. The drill hole peeping instrument probe pushing device in the embodiment is used for peeping a drill hole. The existing drill hole peeping instrument probe cable 1 is provided with a peeping instrument probe body 2. In order to realize the centering of the peeping instrument probe body 2 in the drill hole, the pushing device needs to be provided with a mounting base. Therefore, a metal sleeve end 101 is mounted at the front end of the drill hole peeping instrument probe cable 1 in the embodiment. The peeping instrument probe body 2 is detachably mounted at the sleeve end 101.

[0020] Specifically, the embodiment is provided with Figures 1-5 the structure as shown in the figure. The intermediate shaft seat 3 is threadedly mounted at the sleeve end 101. In order to facilitate disassembly and assembly, an inner threaded shaft hole is arranged at the shaft center of the intermediate shaft seat 3. An outer thread is arranged on the outside of the sleeve end 101. Therefore, the sleeve end 101 can be threadedly mounted at the inner threaded shaft hole first. Then, the peeping instrument probe body 2 is mounted. The peeping instrument probe body 2 is arranged at the shaft center position. The peeping instrument probe body 2 is prevented from directly impacting or rubbing the drill hole wall.

[0021] As shown in the structure as shown in the figure, Figure 6 five vertical sliding seats 31 are arranged around the intermediate shaft seat 3 along the shaft center. An open slot 311 is arranged on each vertical sliding seat 31. Each open slot 311 is aligned with the shaft center of the intermediate shaft seat 3. In addition, a convex ring block 34 is fixedly connected to the outer end of the intermediate shaft seat 3 at the inner threaded shaft hole. A side convex block 32 is fixedly connected to one vertical sliding seat 31. Two cavities are separated by a partition 321 in the driving groove 3201. A driving gear shaft 7 and a driving motor 8 are coaxially connected and arranged on both sides of the driving groove 3201. The driving motor 8 drives the driving gear shaft 7 to rotate.

[0022] In order to be suitable for drill holes with different diameters, it is considered that the pushing unit 4 can be detachably mounted in the open slot 311. That is, the pushing unit 4 is vertically inserted into the five open slots 311. The five circular arc top plates 41 form an intermittent circular structure. The pushing unit 4 is Figure 7 and Figure 8As shown in the structure, the pushing unit 4 includes an insertion rod 47 fixedly connected to the inner side of the arc top plate 41 and inserted into the open slot 311, and a cylindrical clamping block 48 is fixedly installed on the outer end of the insertion rod 47; in this embodiment, a rotating disk 5 is rotatably installed at the convex ring block 34, and the rotating disk 5 is engaged with the transmission gear 6. At the same time, a sliding groove 501 for slidingly clamping the cylindrical clamping block 48 is provided on the rotating disk 5; a transmission gear 6 is rotatably installed on the side protrusion 32 through the rotating shaft 33, and the transmission gear 6 is engaged with the driving gear shaft 7; Figure 5 As shown, the sliding groove 501 has an arc structure in which the distance from the inside to the axis gradually increases from the inside to the outside, that is, during the rotation process, the pushing unit 4 is opened and closed by moving the cylindrical block 48 along the sliding groove 501, which makes it easy to fit in drill holes of different diameters and keep the peephole probe body 2 in a centered state.

[0023] like Figure 7 and Figure 8 In the structure shown, insert blocks 411 are provided on both sides of the arc top plate 41, and an insert cavity 4101 for inserting the insert block 42 is provided in the insert block 411. A mounting bracket 43 is detachably mounted on the outer end of the insert block 42, and a roller 44 is detachably mounted on the mounting bracket 43 via a side rotating seat 45. In order to maintain the effect of fitting with the drilled hole wall, the central axis of the roller 44 and the insert block 42 in this embodiment is aligned with the axis of the intermediate shaft seat 3.

[0024] Taking into account the problem of local unevenness on the borehole wall, mobility needs to be maintained during the actual peeping process. Therefore, in this embodiment, a spring 46 is connected between the bottom of the inner cavity 4101 and the insert block 42 to provide elastic deformation space to cope with the local uneven hole wall. At the same time, in this embodiment, a micro stepping motor is installed on the roller 44 to obtain a stable and reliable movement effect to cope with non-vertical drilling detection operations; in addition, in order to avoid the instability of the drilling structure and the accumulation of fallen slag on the roller 44 affecting the rotation, an anti-stuck groove 431 is provided on the mounting frame 43, which is aligned with the position of the roller 44 and has an inwardly recessed U-shaped structure.

[0025] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0026] It is apparent for a person skilled in the art that the present application is not limited to the details of the above described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the application being defined by the appended claims rather than the above description, and all changes coming within the meaning and equivalency range of the claims are intended to be embraced therein.
