Description

Technical Field

[0001] The invention belongs to the technical field of mining monitoring equipment and relates to a hole surveying device, in particular to a rodless wireless drilling peep instrument for mining. Background Art

[0002] The borehole peep instrument is mainly used for the detection and evaluation of geological conditions during production and construction such as coal mine production and tunnel support design. It is used to observe the coal seam structure, surrounding rock cracks and delamination, loose circle range, tunnel surrounding rock support or grouting reinforcement effect, especially the observation of delamination of the tunnel roof supported by anchor nets and the observation of the rock layer structure of the working face roof, which can be displayed intuitively and clearly on the display.

[0003] The borehole peepholes currently on the market have a complex structure and need to be repeatedly carried in the hole. In addition, the anti-fouling cap is subjected to external force during the use and pushing process, causing some components to damage the lens. Therefore, it is urgent to improve the borehole peephole to solve the above problems. Summary of the invention

[0004] The present invention overcomes the shortcomings of the prior art and proposes a rodless wireless drilling peep device for mining; the present invention is achieved through the following technical solutions: A rodless wireless drilling peep instrument for mining comprises a peep instrument body, a peep instrument probe is provided at the front end of the peep instrument body, and the peep instrument body is connected with a spiral lifting mechanism and an anti-fouling mechanism; the anti-fouling mechanism comprises an anti-fouling cap, a spring, a smooth flat plate and a card slot; one end of the spring is connected to the inner top of the anti-fouling cap, and the other end is connected to the upper surface of the smooth flat plate; a circle of upwardly curved card slots is arranged at the bottom edge of the anti-fouling cap; support plates are symmetrically arranged on both sides of the peep instrument probe; the inner wall of the support plate is connected to the side wall of the peep instrument probe through a telescopic spring, and a downwardly curved groove is arranged on the top of the support plate, and when the telescopic spring is compressed, the card slot is engaged with the groove, and the anti-fouling cap is sleeved on the outer side of the peep instrument probe; The spiral lifting mechanism includes a spiral shell, a rotating buckle and a spiral structure; the rotating buckle is connected to a rotating motor that can rotate forward and reverse, the output end of the rotating motor is connected to the spiral shell, and the rotating buckle is fixedly connected to the peep device body; the outer wall of the spiral shell is provided with a spiral structure; The main body of the peephole moves to the deepest part of the hole through the spiral lifting mechanism. After the forward thrust causes the anti-fouling cap to fall off, the rotating motor drives the spiral outer shell to rotate and move slowly outward, while observing from the inside to the outside from the deep.

[0005] Furthermore, the diameter of the smooth flat plate is larger than the diameter of the peep instrument probe and smaller than the inner diameter of the anti-fouling cap, and the smooth flat plate is located inside the anti-fouling cap.

[0006] Furthermore, a control line is connected to the controller of the rotating motor, and the forward and reverse rotation of the rotating motor is driven by the control line.

[0007] Furthermore, two rotating buckles are arranged in the spiral housing, and the two rotating buckles are respectively connected to a rotating motor.

[0008] Furthermore, after the observation is completed, the observation data can be exported by connecting the USB interface provided on the main body of the peep instrument via a data cable.

[0009] Furthermore, a charging port is provided on the main body of the peephole.

[0010] Furthermore, a connecting ring is provided at the bottom of the viewing device body, and a nylon line is tied to the connecting ring to assist in recovering the viewing device.

[0011] The beneficial effects of the present invention compared with the prior art are as follows: 1. The present invention enables the peep instrument to be stably raised and lowered in the hole, avoiding the heavy equipment handling and greatly improving the efficiency of drilling peep. At the same time, due to the spiral structure, when it encounters obstacles such as small stones on the way forward, the obstacles can be transported to the lower part of the peep instrument along the spiral. When the peep instrument reaches the bottom of the hole, the spring deformation in the anti-fouling cap is greater than the height of the card slot, and the anti-fouling cap falls off.

[0012] 2. The present invention is a rodless wireless drilling peep instrument. In order to prevent the anti-fouling cap from being damaged by the spring due to external force during the advancement process, a smooth plate is connected to the end of the spring to increase the force-bearing area while avoiding scratches on the lens. The elastic force of the spring makes the anti-fouling cap more stable, ensuring that the anti-fouling cap can be stably pushed to the bottom of the hole before falling off under the condition of complex holes.

[0014] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0015] See also Figures 1 to 3 The present embodiment proposes a rodless and wireless anti-fouling drilling peephole device for mining, including a peephole body 1, which is connected to a spiral lifting mechanism and an anti-fouling mechanism; the peephole body 1 used in the present embodiment has a predetermined length, wherein the predetermined length of the peephole body 1 is determined according to the number and size of cameras and other devices, and a peephole probe is provided at the front end of the peephole body 1. The overall structure of the peephole body 1 is prior art, and the embodiment of the present invention does not specifically limit this.

[0016] The anti-fouling mechanism includes an anti-fouling cap 6, a spring 7, a smooth flat plate 8 and a slot 9. The anti-fouling cap 6 can perfectly cover the peephole probe, and is used to protect the peephole probe during the process of sending the peephole body 1 into the drill hole. One end of the spring 7 is connected to the inner top of the anti-fouling cap 6, and the other end is connected to the upper surface of the smooth flat plate 8; the smooth flat plate 8 is located on the inner side of the anti-fouling cap 6; a circle of upward curved slots 9 are provided on the bottom edge of the anti-fouling cap 6; the slots 9 are used to clamp the anti-fouling cap 6 with the peephole probe on the top of the peephole body 1; support plates 10 are symmetrically arranged on both sides of the peephole probe; the inner wall of the support plate 10 is connected to the side wall of the peephole probe through a telescopic spring 13, and a downward curved groove is provided on the top of the support plate 10. When the telescopic spring 13 is compressed, the slot 9 is clamped with the groove.

[0017] It should be noted that the maximum deformation of the spring 7 is slightly greater than the height of the slot 9, and the diameter of the smooth flat plate 8 is slightly greater than the diameter of the peephole probe and slightly smaller than the inner diameter of the anti-fouling cap 6 for ease of use.

[0018] The spiral lifting mechanism includes a spiral shell 2, a rotating buckle 4 and a spiral structure 3; a rotating motor is connected to the rotating buckle 4, and the output end of the rotating motor is connected to the spiral shell 2, and the spiral shell 2 is driven to rotate by the rotating motor, and the outer wall of the spiral shell 2 is provided with a spiral structure 3; the rotating buckle 4 is used to be fixedly connected with the peep device body 1. A control line 15 is connected to the controller of the rotating motor, and the control line 15 drives the forward and reverse rotation of the rotating motor.

[0019] The spiral shell 2 is put on the outer wall of the peephole body 1, and the spiral shell 2 is connected to the peephole body 1 by rotating the buckle 4; the peephole body 1 is placed in a hole of corresponding aperture; the control line 15 is located outside the hole, and by turning on the forward power switch on the control line 15, the rotating motor drives the spiral shell 2 to rotate counterclockwise, so that the peephole body 1 slowly rises. At the same time, due to the spiral structure 3 on the outer wall of the spiral shell 2, when it is hindered by small stones on the way forward, the obstacles can be transported to the lower part of the peephole body 1 along the spiral structure 3. When the peephole body 1 reaches the bottom of the hole, the anti-fouling cap 6 touches the bottom of the hole, and the spring 7 is compressed. When the deformation of the spring 7 is greater than the height of the card slot 9, the card slot 9 is disengaged from the groove of the support plate 10, and the anti-fouling cap 6 falls off; at the same time, the elasticity of the telescopic spring 13 is released, and the support plate 10 pops out to touch the hole wall for supporting the peephole body 1.

[0020] Then, the reverse power switch on the control line 15 is pulled to make the rotating motor rotate in the opposite direction, driving the spiral shell 2 to rotate clockwise. Due to the supporting effect of the support plate 10, the peephole probe will not be affected by the rotation of the spiral shell 2, and stable observation can always be achieved. As the spiral shell 2 rotates clockwise, the peephole body 1 is driven to slowly descend until the peephole reaches the orifice, and the observation ends.

[0021] It should be noted that after the peephole body 1 moves to the deepest part of the hole and the thrust of continued advancement causes the anti-fouling cap 6 to fall off, the rotating motor drives the spiral housing 2 to rotate and slowly move outward, while observing from the inside to the outside from the deep.

[0022] There are enough intervals between the spiral structures 3 to transfer small obstacles to the bottom of the peep device body 1 so that they will not hinder passage.

[0023] In order to ensure that the peep device has sufficient power to rise and fall, two rotating buckles 4 can be arranged in the spiral housing 2, and the two rotating buckles 4 are respectively connected to a rotating motor.

[0024] For meeting the requirement of different aperture holes, the spiral shell 2 of multiple apertures can be set so that the peep instrument can be observed in different apertures. The spiral shell 2 is made of light materials to reduce the deadweight of the peep instrument as far as possible, and is convenient to the lifting of the peep instrument.

[0025] When the hole collapses seriously or the front makes it impossible for the peep sight to move forward, the anti-fouling cap 6 will fall off in advance, causing the spiral housing 2 to rotate in the opposite direction, and the peep sight will fall to avoid loss.

[0026] The smooth plate 8 at the end of the spring 7 is circular, and in order to prevent the smooth plate from shaking significantly, its diameter needs to be larger than the diameter of the peep device probe.

[0027] After the observation is finished, the observation data is exported through the USB interface 11 provided on the peep instrument body 1 via a data cable. A charging port 12 is provided on the peep instrument body 1 .

[0028] In order to avoid the loss caused by the failure of the peephole or the serious deformation of the hole, the peephole cannot move forward, a connecting ring 14 can be set at the bottom of the peephole body 1, and a nylon line with a diameter of 0.148mm is tied on the connecting ring 14 to facilitate the recovery of the peephole.

[0029] The control line 15 is sensitive enough to ensure that the rotating motor can reverse in time.

[0030] The above content is a further detailed description of the present invention in combination with a specific preferred embodiment. It cannot be determined that the specific embodiments of the present invention are limited to this. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the present invention, which should be regarded as belonging to the present invention and the scope of patent protection determined by the submitted claims.
