Description

Technical Field

[0001] The present invention relates to the technical field of tunnel monitoring, and in particular to a rockburst tunnel monitoring device and an early warning system. Background Art

[0002] Tunnel rockburst is a kind of rock destruction activity that occurs during tunnel construction. Its destruction characteristics are more violent than tunnel collapse, which is more harmful to people and equipment. Tunnels must pass through hard surrounding rocks and are located in high geostress areas. High geostress refers to the initial geostress of 20-25MPa when the maximum principal stress of the rock mass is greater than that of the rock mass. Rock has high brittleness and elasticity, which enables it to store a large amount of elastic strain energy during structural transformation and superficial transformation. Rockburst may occur continuously for a period of time, causing great trouble to construction. And when the rock bursts and ejects, it poses a serious threat to construction personnel and equipment.

[0003] There are many common methods for monitoring rockburst tunnels, which are usually used in combination to ensure accurate prediction and timely response to rockbursts. These methods include 3D photogrammetry and rock structure analysis technology, which uses 3D photogrammetry technology to quickly collect the structural parameters of the tunnel surrounding rock, combined with rock structure analysis to evaluate the stability of the rock mass and the risk of rockburst.

[0004] Traditional rockburst tunnel monitoring devices require manual operation, which increases the risk of tunnel monitoring and has relatively low monitoring scanning efficiency.

DETAILED DESCRIPTION

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] The monitoring mechanism includes a kinetic energy component, an adaptive component and a scanning component, and an alarm mechanism is connected to one side of the kinetic energy component. The kinetic energy component includes a motor 4, which is fixedly connected to one side of a device housing 3, and a rotating rod 5 is fixedly connected to one side of an output end of the device housing 3. The rotating rod 5 penetrates the outer wall of the device housing 3 and is rotatably connected to the device housing 3.

One side of the top of the sliding sleeve block 8 is hollow, and the top of the sliding sleeve block 8 is horizontally slidably connected to the adaptive component.

[0041] The implementation principle of the rockburst tunnel monitoring device and early warning system in the embodiment of the present application is:

[0042] The motorized wheel 2 at the bottom can be positioned on the basis of the scanner 22 and moved by means of the motorized wheel 2. When cyclic monitoring is required, the starting motor 4 can slide the sliding sleeve block 8 back and forth horizontally along the spiral guide of the spiral guide groove 6 under the sliding connection between the spiral guide groove 6 and the ball block, and drive the sliding sleeve block 8 to slide along the horizontal side of the bottom end of the U-shaped sliding groove 7 and drive the scanning component to slide.

[0043] Example 2: Combination Figure 2-Figure 5 Based on Example 1, this embodiment is further improved in that:

[0044] The adaptation component includes a slider 10, one side of which is fixedly connected to a slide plate 9, which is horizontally slidably connected to the top of a sliding sleeve block 8, and the bottom of the slider 10 is relatively slidably connected to a sliding plate 11, and the bottom of the sliding plate 11 is relatively slidably connected to the grooves on both sides of the U-shaped.

[0049] As the sliding sleeve block 18 drives the slider 10 to slide horizontally back and forth along the sliding plate 11, the slider 14 and the slider 2 15 can slide on the oblique slot 24 and the four-side slot 23 respectively, and when the slider 2 15 slides to the corner of the four-side slot 23, the slider 2 15 can be pushed to the turning point of the four-side slot 23 under the elastic action of the spring 16, and as the slider 2 15 slides to the other end of the four-side slot 23, the sliding plate 11 can be synchronously pulled to slide along both sides of the sliding slot 7, so as to drive the scanner 22 to move relatively, thereby driving the scanning component to move, and increasing the scanning area of ​​the scanner 22, so as to improve the scanning data comparison.

[0050] Example 3: Combination Figure 4 and Figure 5 Based on Example 1 and Example 2, this embodiment is further improved in that:

[0051] The scanning component includes a groove opening 17, which is opened at the top of the sliding plate 11. A rack plate 18 is fixedly connected in the groove opening 17.

[0052] The four-side slots 23 are parallelogram-shaped, and the oblique slots 24 are inclined, so as to ensure that the slide bar 15 can slide completely along the four-side slots 23 .

[0053] The implementation principle of the rockburst tunnel monitoring device and early warning system in the embodiment of the present application is:

[0054] As the slider 10 moves back and forth along the sliding plate 11, the gear 19 is meshed with the rack plate 18 and can rotate at the slider 10, driving the scanner 22 at the top to fully scan the inner wall of the tunnel and increase the scanning range as the displacement of the adaptable component changes.

[0055] Example 4: Combination Figure 2 , Figure 3 , Figure 4 and Figure 6 Based on Example 1, Example 2 and Example 3, this embodiment is further improved in that:

[0056] The alarm mechanism comprises two rotating sleeve blocks 26 , the top ends of the two rotating sleeve blocks 26 are both rotatably connected with rotating outer rods 27 , and the two rotating outer rods 27 are internally threadedly connected with screw rods 32 .

[0059] The implementation principle of the rockburst tunnel monitoring device and early warning system in the embodiment of the present application is:

[0060] As the displacement of the sliding sleeve 8 changes, the fixed ring 25 will be used to pull the pull rope 31 for transmission, so that the rotating outer rod 27 can be synchronously driven to reciprocate under the sleeve transmission of the two rotating outer rods 27. By utilizing the vertical sliding of the limit vertical rod 30 and the limit ring 29, the alarm 28 can be driven to undergo vertical displacement changes when the rotating outer rod 27 rotates. When data abnormality is detected, the alarm 28 will be activated and move back and forth vertically to increase the coverage of the equipment.
