Description

Technical Field

[0001] This invention relates to the field of borehole detection technology, specifically to an automatic pushing device for borehole detection instruments in hazardous areas. Background Technology

[0002] In the fields of mining, tunneling, and underground engineering, drilling technology is often used for the detection and mitigation of hazards such as impacts and coal and gas outbursts. To understand the quality of drilling construction, instruments such as borehole inspection and borehole trajectory measurement need to be precisely pushed into the borehole for inspection. Currently, a pusher-type pushing device is commonly used to push the detection instrument, that is, the detection probe is installed at one end of the pusher, and the probe is pushed into the borehole by the pusher. This pushing method has the following shortcomings in terms of structure, connection method, and use: ① The pusher is thin and not conducive to deep hole detection; ② The bolted connection between the pushers affects the continuity of propulsion and is time-consuming; ③ Manual pusher cannot be pushed continuously at a constant speed and cannot accurately measure the propulsion position; ④ Manual pusher pushing in dangerous areas has a high risk factor and high labor intensity. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic pushing device for borehole inspection instruments in dangerous areas, which can effectively improve the safety and testing accuracy of borehole inspection and measurement operations in dangerous areas, and better realize unmanned inspection of boreholes in dangerous areas.

[0004] To achieve the above objectives, the present invention provides an automatic pushing device for borehole inspection instruments in hazardous areas, comprising a detection device, a driving device, and a meshing chain. The detection device includes a probe and a data cable connected to the probe. The meshing chain includes chain I and chain II, which are of the same specifications. Chain I includes multiple outer links and multiple inner links, with each pair of outer links rotatably connected by an inner link. The outer links on chain I and chain II are connected as a single unit through mutual meshing and separate when disengaged. The probe is mounted at the end of the meshing chain. When chain I and chain II are engaged, the data cable is located inside them. The engagement and disengagement of chain I and chain II are performed by the driving device, which includes... The system includes a servo pulse motor I, a servo pulse motor II, a sprocket I, and a sprocket II. Sprocket I is located outside of chain I and engages with chain I, driving chain I forward and backward. Sprocket II is located outside of chain II and engages with chain II, driving chain II forward and backward. Servo pulse motor I is rotatably connected to sprocket I, driving sprocket I to rotate. Servo pulse motor II is rotatably connected to sprocket II, driving sprocket II to rotate. When chains I and II are engaged together, the probe is driven by the drive device to advance within the borehole and perform data measurement. After the data measurement is completed, the probe is withdrawn from the borehole by the drive device, and chains I and II separate.

[0005] Furthermore, the device also includes a support box, which includes a cover and a bottom. A chain engagement auxiliary mechanism is installed on the bottom of the box to assist in the engagement and disengagement of chain I and chain II. The chain engagement auxiliary mechanism includes a vertical limiting channel and a horizontal limiting channel. The vertical limiting channel is perpendicular to the horizontal limiting channel and is located at the top center of the horizontal limiting channel. The vertical limiting channel assists in the engagement of chain I and chain II. The horizontal limiting channel includes an integrally formed left cavity, a right cavity, and a vertical guide block. The left cavity is for chain I to pass through, and the right cavity is for chain II to pass through. The vertical guide block is located at the upper center of the horizontal limiting channel and is perpendicular to the left and right cavities, assisting in the disengagement of chain I and chain II.

[0006] Furthermore, a data cable channel is provided at the bottom of the lateral limiting channel.

[0007] Furthermore, sprocket I and sprocket II are of the same specifications. A drive shaft is installed at the center of sprocket I. A seated bearing I is installed at one end of the drive shaft, and a gear I is fixed at the other end. A seated bearing II is also installed on the inner side of gear I.

[0008] Furthermore, sprocket I and sprocket II are mounted on the bottom of the box. Sprocket I is mounted above the left cavity and on the left outer side of the vertical guide block. Sprocket II is mounted above the right cavity and on the right outer side of the vertical guide block. The seated bearing I is fixed in the mounting hole on the bottom of the box.

[0009] Furthermore, the support box also includes an inner box, which is fixedly connected to the inner side of the box cover, and the bearing II with seat is fixedly installed in the mounting hole opened in the inner box; the main bodies of the servo pulse motor I and the servo pulse motor II are installed on the outer surface of the box cover, and the gear II on its rotating shaft meshes with the gear I.

[0010] Furthermore, the support box has a convex shape, the probe can extend from the top of the support box, chain I extends from the left side of the support box, and chain II extends from the right side of the support box.

[0011] Furthermore, the meshing chain also includes a connecting seat, which is located at the top of the meshing chain. The probe is mounted on the upper surface of the connecting seat, and the lower end of the connecting seat is rotatably connected to the outer link of chain I and the outer link of chain II, respectively.

[0012] The beneficial effects of this invention are as follows: Compared with the prior art, this device has the following advantages:

[0013] (1) Compared with manual pushing, the use of servo pulse motor drive not only reduces labor intensity, but also effectively avoids the potential disaster hazards that threaten personnel safety during dangerous area detection;

[0014] (2) The double-chain meshing method of transportation has a stronger pushing capacity than push rod pushing, and is more adaptable to deep hole detection and drilling detection of vertical top plate.

[0015] (3) The length of the meshing link and the propulsion length are precisely controllable;

[0016] (4) Signal transmission is safer. In the prior art, signal transmission cables are not only exposed in the work area, but also the longer the distance, the greater the impact of their own weight and friction, making them easy to be tensile and damaged. In this invention, the signal transmission cable is wrapped by the meshing chain group, and the force is uniform, making it safer. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, an automatic pushing device for borehole inspection instruments in hazardous areas includes a detection device, a driving device, and a meshing chain. The detection device includes a probe 1 and a data cable 2 connected to the probe 1. The meshing chain includes chain I3 and chain II4, which are of the same specifications. Figure 5 As shown, chain I3 includes multiple outer links 3-1 and multiple inner links 3-2. Each pair of outer links 3-1 is rotatably connected via an inner link 3-2. The outer links 3-1 on chain I3 are interlocked with the outer links 3-1 on chain II4, forming a single unit; they separate when disengaged. Specifically, each outer link 3-1 has two connecting holes at both ends, and each inner link 3-2 also has two connecting holes. On chain I, one end of an outer link (3-1) is connected to one end of an inner link (3-2) via a pin, and the same applies to chain II. The same configuration and connection are present on chain II. The mechanism of the interlocking chain is similar to that of a zipper. The meshing chain also includes a connecting seat 3-3, which is located at the top of the meshing chain. The probe 1 is installed on the upper surface of the connecting seat 3-3. The lower end of the connecting seat is rotatably connected to the outer link 3-1 of chain I3 and the outer link 3-3 of chain II4, respectively.

[0025] When chain I3 and chain II4 are engaged, data cable 2 is located inside them, effectively protecting it from wear. The engagement and disengagement of chains I3 and II4 are controlled by a drive mechanism including servo pulse motor I5, servo pulse motor II6, sprocket I7, and sprocket II8. Sprocket I7 is located outside chain I3 and engages with it, driving chain I3 forward and backward. Sprocket II8 is located outside chain II4 and engages with it, driving chain II4 forward and backward. Servo pulse motor I5 is rotatably connected to sprocket I7, driving sprocket I7 to rotate. Servo pulse motor II6 is rotatably connected to sprocket II8, driving sprocket II8 to rotate. The probe's travel speed can be controlled by servo pulse motors I5 and II6. When chains I3 and II4 are engaged, the drive mechanism propels probe 1 forward within the borehole, performing data measurements. After data measurement is completed, probe 1 is withdrawn from the borehole by the drive device, and chain I3 separates from chain II4. This structure is well-suited for borehole exploration in hazardous environments, exhibiting excellent adaptability and safety. The meshing chain is rigid, providing better control for deep hole exploration, and it can perform exploration without contacting the borehole wall, preventing wear or failure of the meshing chain. The probe is also very easy to withdraw after borehole exploration.

[0026] like Figure 2 As shown, the device also includes a support box, which includes a cover 14 and a bottom 15. A meshing chain auxiliary mechanism is installed on the bottom 14 to assist in the engagement and disengagement of chain I3 and chain II4. The meshing chain auxiliary mechanism includes a vertical limiting channel 17 and a horizontal limiting channel 18. The vertical limiting channel 17 and the horizontal limiting channel 18 are set vertically. The vertical limiting channel 17 is located at the center above the horizontal limiting channel 18. The vertical limiting channel 17 assists in the engagement of chain I3 and chain II4. The lateral limiting channel 18 includes an integrally formed left cavity 18-1, a right cavity 18-2, and a vertical guide block 18-3. The left cavity 18-1 is for chain I3 to pass through, and the right cavity 18-2 is for chain II4 to pass through. The vertical guide block 18-3 is located in the upper middle position of the lateral limiting channel 18, perpendicular to the left cavity 18-1 and the right cavity 18-2. It is cone-shaped and is used to assist in separating chain I3 and chain II4. A data cable channel 18-4 is provided at the bottom of the lateral limiting channel 18.

[0027] like Figure 4As shown, sprockets I7 and II8 are of the same specifications. A drive shaft 9 is mounted at the center of sprocket I7. One end of the drive shaft 9 is fitted with a seated bearing I10, and the other end is fixed with a gear I12. A seated bearing II11 is also mounted inside the gear I12. Sprockets I7 and II8 are mounted on the bottom of the housing 15. Sprocket I7 is mounted above the left cavity 18-1, on the left outer side of the vertical guide block 18-3. Sprocket II8 is mounted above the right cavity 18-2, on the right outer side of the vertical guide block 18-3. The seated bearing I10 is fixed in the mounting hole in the bottom of the housing 15. The outer ring of the seated bearing I10 remains stationary, while the inner ring rotates with the drive shaft 9.

[0028] like Figure 3 As shown, the support box also includes an inner box 16, which is fixedly connected to the inner side of the cover 14. A seated bearing II11 is fixedly installed in the mounting hole of the inner box 16. The outer ring of the seated bearing II11 remains stationary, while the inner ring rotates with the drive shaft 9. The main bodies of the servo pulse motors I5 and II6 are mounted on the outer surface of the cover 14, and gear II13 on their rotating shaft meshes with gear I12. Gears I12 and II13 are both placed inside the inner box and are specially protected. In this embodiment, the support box has a convex shape, allowing the probe 1 to extend from the top of the support box, the chain I3 to extend from the left side of the support box, and the chain II4 to extend from the right side of the support box. This structure facilitates operation by the operator.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes that can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention are all within the protection scope of the claims of the present invention.
