Description

Technical Field

[0001] The present invention relates to the field of coal mine mining, and particularly to an auxiliary device for bolt drilling. Background Art

[0002] When installing bolts in a coal mine roadway, it is a comprehensive means of actively reinforcing the surrounding rock, improving the stress state and dynamically adapting to deformation to solve the problems of roof caving, rib spalling and dynamic disasters in deep mining. Therefore, before installing the bolts, it is necessary to pre-drill the area where the bolts are to be installed, and then install the bolts.

[0003] The existing solution is that after the current area of coal mine is collected, the support is erected on the surface of the mine tunnel, and the hydraulic support is placed in a stable triangular state. Then, based on the personal experience of the personnel or with the cooperation of a protractor, a driving device is installed on the support, and a drill pipe is installed on its output end. Then, drilling is carried out towards the inside of the roadway. When the drilling is completed, the bolt is sent into the hole for support.

[0004] Although the above technical solution solves the technical problem well, in the actual operation process, due to the different excavation progress of the roadway and the narrow roadway space at the mining site, for large-scale devices, such as installing a device on a loader to drill the inside of the roadway, although the drilling can be carried out according to the set track, it is difficult to enter the drilling area. When a small hydraulic support is installed on the ground, the ground of the mining area is uneven, and the device is prone to tilt during use. When the personnel grasp the driving device to drill, the center of gravity is easy to shift, and the device will also tilt, resulting in the failure of drilling the hole wall. At this time, the wrong hole needs to be filled with grout, and then drilling work is carried out in a new area, resulting in low efficiency. Summary of the Invention

[0005] In view of the problem that the roadway space at the mining site is narrow and it is difficult to drill the inside of the roadway wall in the above or existing technology, the present invention is proposed.

[0006] Therefore, the object of the present invention is to provide an auxiliary device for bolt drilling.

[0009] As a preferred solution of an auxiliary device for anchor bolt drilling in the present invention, wherein: each linear notch is on the same horizontal plane as the sliding notch and is aligned one by one.

[0010] As a preferred solution of an auxiliary device for anchor bolt drilling in the present invention, wherein: the identification component includes a conical button rotatably connected to the surface of the sliding block, and several groups of scale marks are formed on the surface of the conical button with the conical button as the axis.

[0011] As a preferred solution of an auxiliary device for anchor bolt drilling in the present invention, wherein: the anti-reverse component includes a multi-sided plate coaxially arranged with the conical button on the surface of the sliding block, a spring arranged on the surface of the multi-sided plate, and a mating tooth arranged at the end of the spring.

[0012] As a preferred solution of an auxiliary device for anchor bolt drilling in the present invention, wherein: the fastener includes a knob threadedly connected to the surface of the sliding block, and touch lines are formed on the surface of the knob.

[0013] As a preferred solution of an auxiliary device for anchor bolt drilling in the present invention, wherein: the adjustment mechanism includes a second mating tooth coaxially arranged with the conical button on the surface of the sliding block, a fixed plate fixedly connected to the surface of the second mating tooth, a through groove is formed inside the fixed plate, identification grooves are formed on both sides of the through groove on the surface of the fixed plate, a multi-stage rod body is slidably connected inside the through groove, several groups of spirit levels are arranged at the edges of the surface of the fixed plate, a slider is slidably connected to the surface of the spirit level, and a driving member is arranged inside the slider.

[0014] As a preferred solution of an auxiliary device for anchor bolt drilling in the present invention, wherein: the driving member includes a driving motor arranged inside the slider and a mounting pipe arranged at the output end of the driving motor.

[0015] As a preferred solution of an auxiliary device for anchor bolt drilling in the present invention, wherein: the other end of each multi-stage sleeve is fixedly connected to the loading block, and the lengths of one group of multi-stage sleeves and multiple-stage cylinders are respectively smaller than those of the other group of multi-stage sleeves and multiple-stage cylinders.

[0016] As a preferred solution of an auxiliary device for anchor bolt drilling in the present invention, wherein: the first mating tooth limits the second mating tooth in the working state.

[0017] Advantages of an auxiliary device for bolt drilling of the present invention: Through the setting of the support mechanism, it can quickly adjust the angle to support inside the roadway in narrow coal mining areas with large surface undulations, and can be erected at multiple angles. Moreover, affected by the force in the support area, the current area will be compacted, reducing the erection time. At the same time, it is applicable to narrow mine tunnels, achieving the effects of rapid erection and stability.

[0018] Furthermore, through the cooperation of the support mechanism and the adjustment mechanism, under the condition that it is difficult to erect vertically inside the narrow hole wall, when the multi-stage sleeve support is not on the same horizontal plane as the surface center of gravity, it is still possible to adjust the angle of the recognition component by operating the level gauge for identification, reposition it, and then promptly adjust the drilling angle to achieve the effect of quickly finding the right position.

[0019] Furthermore, through the setting of the first mating tooth and the second mating tooth, during the operation of sequentially punching holes in a circular pattern inside the hole wall in the clockwise direction, the punching angle will be restricted. The force exerted by the worker in the punching direction and the force formed by the first mating tooth are balanced, limiting the punching angle, thereby reducing the possibility of angle turning and improving the punching efficiency.

[0020] Furthermore, after the angle adjustment, through the linear sliding of the slider on the multi-stage rod, without the angle deflecting, a linear drilling operation is carried out. When the worker operates to push the slider, it will reduce the probability of punching failure caused by difficulty in standing firm due to surface undulations and the deviation of the own center of gravity resulting in failure to punch the hole wall vertically, as well as the fatigue caused by standing for a long time or misjudgment caused by excessive dust in the environment.

Specific embodiments

[0029] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0030] Refer to Figures 1 to 6 , loading block 100, a sliding notch is provided on the surface of loading block 100, the support mechanism 200 symmetrically arranged at the ends of loading block 100, in the working state, based on the length transformation in the internal space of the mining roadway, the orientation mechanism 300, including a sliding block 301 arranged inside the sliding notch, a fastener 302 is threadedly connected to the surface of sliding block 301, an identification component, rotatably connected to the surface of sliding block 301, used to observe the current construction angle, an anti-reverse component, arranged on the surface of sliding block 301, in the working state, used to limit the deviation of the drilling angle, the adjustment mechanism 400, arranged on the surface of sliding block 301, for drilling work inside the current roadway based on construction requirements.

[0031] Refer to Figures 1 to 2 , the support mechanism 200 includes multi-stage cylinders 201 respectively arranged at the ends of loading block 100, the output end of multi-stage cylinder 201 is fixedly connected to a multi-stage sleeve 202, a linear notch 203 is provided on the surface of multi-stage sleeve 202, multi-stage cylinder 201 is built inside multi-stage sleeve 202, and as multi-stage cylinder 201 moves, the path of multi-stage sleeve 202 becomes longer or shorter. When multi-stage cylinder 201 returns to the initial state, the stage of the multi-stage sleeve 202 closest to loading block 100 will accommodate the remaining stages, and at the same time, a protective treatment is carried out on multi-stage cylinder 201. The coal mining area is in an environment with more dust, and electronic components may be damaged to varying degrees by dust, resulting in a shorter service life.

[0032] During use, the multi-stage cylinder 201 can drive the multi-stage sleeve 202 to be erected at multiple angles in a narrow environment, and the two groups of multi-stage sleeves 202 only need to contact the inner wall of the hole when unfolded.

[0033] Each linear notch 203 is on the same horizontal plane as the sliding notch and is aligned one by one.

[0034] Refer to Figures 4 to 6 As shown in the figure, the sliding block 301 slides on the surfaces of the loading block 100 and the multi-stage sleeve 202, which is convenient for personnel to accurately position the height and for subsequent adjustment of the drilling angle. After finding the appropriate height for the operator, by rotating the knob 3021 onto the loading block 100 and the multi-stage sleeve 202, the sliding block 301 is limited to prevent its position from shifting on the loading block 100 and the multi-stage sleeve 202 during the working state.

[0035] The identification component includes a conical button 310 rotatably connected to the surface of the sliding block 301, and a number of scale marks 311 are provided on the surface of the conical button 310 with the conical button 310 as the axis.

[0036] The anti-reverse component includes a multi-sided plate 320 coaxially arranged with the conical button 310 on the surface of the sliding block 301, a spring 321 arranged on the surface of the multi-sided plate 320, and a mating tooth 322 arranged at the end of the spring 321. The multi-sided plate 320 can be fixed to the surface of the sliding block 301 by bolts. The spring 321 will give a driving force to the mating tooth 322 in the working state of the device, thereby limiting the adjustment mechanism 400, so that the adjustment mechanism 400 can only perform a clockwise circular motion in the working state, which is convenient for personnel to apply force to the adjustment mechanism 400. When the adjustment mechanism 400 is subjected to a counterclockwise force, the angle of the adjustment mechanism 400 is restricted.

[0037] The fastener 302 includes a knob 3021 threadedly connected to the surface of the sliding block 301. The surface of the knob 3021 is provided with touch lines 3022, and the knob 3021 is internally threaded. When rotated, the surface of the sliding block 301 is also threaded. The knob 3021 moves in the opposite direction of the adjustment mechanism 400 to limit and fix the sliding block 301.

[0038] The adjustment mechanism 400 includes two mating teeth 401 coaxially arranged with the conical knob 310 on the surface of the sliding block 301. The two mating teeth 401 are in the shape of a tooth plus a rod. The two mating teeth 401 are inside the spring 321 and are rotatably connected to the sliding block 301. When the two mating teeth 401 on the sliding block 301 rotate, the spring 321 is not affected by it, and due to the rod-shaped part of the two mating teeth 401 inside for support, the spring 321 does not skew in the working state. A fixed plate 402 is fixedly connected to the surface of the two mating teeth 401. A through groove is formed inside the fixed plate 402. Identification grooves are formed on both sides of the through groove on the surface of the fixed plate 402. When personnel perform drilling work, first observe whether the bubble inside the level 404 is in the centered state. Then, when the bubble is centered (i.e., horizontal with the ground center of gravity), rotate the conical knob 310 to make the horizontal direction of the scale mark 311 be on the same horizontal line as the identification groove, which is convenient for the staff to record the deviation angle and adjust the drilling angle. A multi-stage rod body 403 is slidably connected inside the through groove. Several groups of levels 404 are arranged at the edge of the surface of the fixed plate 402. A slider 405 is slidably connected to the surface of the level 404. A driving member 406 is arranged inside the slider 405. The slider 405 and the multi-stage rod body 403 cooperate with each other to perform straight drilling, further reducing errors.

[0039] The driving member 406 includes a driving motor 4061 arranged inside the slider 405, and a mounting tube 4062 arranged at the output end of the driving motor 4061. The drill rod is installed inside the mounting tube 4062, and then the drill rod is driven to rotate by the driving motor 4061, and then the drilling operation is carried out.

[0040] In actual use, due to the narrow and special nature of the current environment, the drill rod is not only spliced by multiple sections of threads, but also needs to measure the drill rod for drilling multiple times when the drilling depth reaches a certain level to avoid the hole skewing. When the angle deviation ≤ 1°, the stability effect of the anchor rod becomes poor, and the roadway roof fall caused by uneven stress of the anchor rod and the anchoring failure is avoided. When the angle deviation is 5°, the anchoring force can be reduced by more than 20%, and it is checked once every 0.5 m of drilling. When the slight deviation ≤ 3°, it can be gradually corrected by rotating the drill rod or adjusting the propulsion force.

[0041] The other end of each multi-stage sleeve 202 is fixedly connected to the loading block 100. The lengths of one group of multi-stage sleeves 202 and multi-stage cylinders 201 are respectively less than the lengths of the other group of multi-stage sleeves 202 and multi-stage cylinders 201.

[0042] One mating tooth 322 limits the two mating teeth 401 in the working state.

[0044] When in use, the operator grasps the loading block 100 and then operates the multi-stage cylinder 201 to work. The multi-stage cylinder 201 unfolds the multi-stage sleeve 202. Then, the sliding block 301 is slid to a proper position. Subsequently, the knob 3021 is rotated to limit and fix the sliding block 301. Then, the level 404 is observed and adjusted. When the bubble in the level 404 is centered, after rotating the tapered knob 310 to adjust the angle, the fixed plate 402 is rotated to a proper angle. When the multi-stage cylinder 201 is vertically erected along the direction of the ground center of gravity, the tapered knob 310 does not need to be rotated. Then, the drill rod is installed inside the installation pipe 4062. Subsequently, the multi-stage rod body 403 is unfolded to a proper distance. The drive motor 4061 inside the slider 405 is started, so that the drive motor 4061 drives the drill rod inside the installation pipe 4062 to start working. As the drill rod works, the operator synchronously pushes the slider 405 along the track of the multi-stage rod body 403, so that the drill rod can drill a straight hole. When the drilling is completed, the slider 405 is retracted close to the loading block 100, and at the same time, the extended part of the multi-stage rod body 403 is retracted. When annular drilling is required inside the hole wall, the angle of the fixed plate 402 is rotated, and the scale mark 311 is observed. Then, the above operations are repeated.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
