A simulation device for advanced geological prediction detection of poor geological bodies in tunnels

Abstract

The present invention relates to the field of geological prediction and detection technology, and discloses a simulation device for advanced geological prediction and detection of unfavorable geological bodies in tunnels, comprising a mounting unit, a transmission unit, and a collection unit. In the present invention, a worker activates a driving component so that the driving component can drive a rectangular mounting tube to move horizontally and rotate at the same time. Because a positioning rod is provided in the inner cavity of the rectangular mounting tube, and the positioning rod is fixedly mounted on a circular sleeve, the positioning rod can only rotate and not move. Therefore, when the rectangular mounting tube moves, a wedge block can be pressed against a fixed block fixedly mounted on the positioning rod, thereby enabling the wedge block to drive a collection box to move horizontally, until the fixed block is pressed against an inclined plate, enabling a sealing plate provided in the collection box to be opened, thereby allowing soil scraped off during the rotation of the collection box to enter the collection box.

Description

Technical Field

[0001] The invention belongs to the technical field of geological prediction and detection, and in particular relates to an advanced geological prediction and detection simulation device for poor geological bodies in tunnels. Background Art

[0002] Tunnel advanced geological prediction involves assessing the geological conditions ahead of the excavation face of the rock and soil mass to be constructed before construction begins on some underground tunnel projects. This allows the contractor to understand the structure, properties, and state of the rock and soil mass at the construction site, as well as to predict adverse geological conditions such as groundwater, gas, and rock and soil stress. Commonly used methods for tunnel advanced geological prediction include drilling sampling and analysis, and simulating information about adverse geological conditions through multiple sampling attempts.

[0003] However, when conducting geological forecast detection on existing tunnel poor geological bodies, holes are often opened and the soil that falls from the holes is collected by collecting equipment. Although this method can collect the fallen soil, it is often unable to collect the soil on the entire circular surface of the tunnel opening, which will result in insufficient sampling during collection.

A wedge block 303 is dynamically provided, and the four wedge blocks 303 are symmetrical with each other. The four wedge blocks 303 are fixedly connected to a collection box 305 at one end away from the rectangular slot 3011, and a drill bit 1021 is fixedly connected to one end of the rectangular mounting tube 301; the transmission unit 200 includes a driving assembly, which is used to drive the drill bit 1021 to rotate, and the driving assembly is also used to drive the collection box 305 to rotate and move horizontally, and a mounting slot 3052 is provided on one side wall of each collection box 305. The staff starts the driving assembly so that the driving assembly can drive the rectangular mounting cylinder 301 to move horizontally and rotate at the same time. Because the inner cavity of the rectangular mounting cylinder 301 is provided with a positioning rod 302, and the positioning rod 302 is fixedly mounted on the circular sleeve 2021, the positioning rod 302 can only rotate but not move. Therefore, when the rectangular mounting cylinder 301 moves, the wedge block 303 will be able to squeeze on the fixed block 3021 fixedly mounted on the positioning rod 302, so that the wedge block 303 can drive the collection box 305 to move horizontally, until the fixed block 3021 is squeezed on the inclined plate 304, which can enable the sealing plate 3053 set in the collection box 305 to open, so that the soil scraped during the rotation of the collection box 305 can enter the collection box 305.

[0039] like Figures 1 to 5As shown, in a specific embodiment, the drive assembly includes a servo motor 201, which is mounted on a side wall of the protective shell 102. The output end of the servo motor 201 is fixedly connected to a threaded rod 2011, which movably extends through the protective shell 102. The other end of the threaded rod 2011 is fixedly connected to a circular fixing plate 202. A threaded sleeve 2012 is engaged and mounted on the threaded rod 2011. Two symmetrical guide rods 2013 are movably extended through the threaded sleeve 2012.

[0041] like Figure 5 As shown, the first sliding mechanism further includes two first sliding grooves 2022, which are respectively provided on the inner wall of the circular sleeve 2021. The two first sliding grooves 2022 are symmetrical with each other. First sliders 2023 are slidably mounted in the inner cavities of the two first sliding grooves 2022. The two first sliders 2023 are symmetrical with each other. A circular movable plate 2024 is fixedly connected to the side wall of the two first sliders 2023 facing each other. A rectangular plug-in rod 2025 is fixedly connected to the side wall of the circular movable plate 2024 away from the threaded rod 2011. The end of the rectangular plug-in rod 2025 away from the circular movable plate 2024 is fixedly connected to the circular mounting plate 203. The end of the circular mounting plate 203 away from the threaded rod 2011 is fixedly connected to the rectangular mounting cylinder 301. In this configuration, the installation position and components of the first sliding mechanism are determined.

[0042] like Figures 3 and 4As shown, a circular groove 2031 is provided on one side wall of the circular mounting plate 203 near the threaded rod 2011. Two symmetrical guide sliders 2032 are slidably mounted in the inner cavity of the circular groove 2031. The two guide sliders 2032 are fixedly connected to a connecting rod 2034 on one side wall away from the circular mounting plate 203. The two connecting rods 2034 are symmetrical to each other, and the other ends of the two connecting rods 2034 are fixedly connected to the threaded sleeve 2012. In this configuration, because the circular mounting plate 203 is provided with a circular groove 2031 and two symmetrical guide sliders 2032 are slidably mounted in the inner cavity of the circular groove 2031, and one end of the guide slider 2032 away from the circular groove 2031 is fixedly connected to the connecting rod 2034, and the other end of the connecting rod 2034 is fixedly connected to the threaded sleeve 2012, the circular mounting plate 203 can rotate and move horizontally at the same time.

[0043] Example 2:

[0044] The difference between the above embodiment and this embodiment is that: Figure 5 and Figures 7 and 8 As shown, a simulation device for advanced geological prediction and detection of unfavorable geological bodies in tunnels is shown. A rectangular plug-in rod 2025 and a circular movable plate 2024 are provided with slots. A positioning rod 302 is positioned within the slots. One end of the positioning rod 302 is fixedly connected to the inner cavity of a circular sleeve 2021. The other end of the positioning rod 302 is movable through a rectangular mounting tube 301. A fixing block 3021 is fixedly mounted at the end. In this configuration, the installation position of the positioning rod 302 is determined.

[0045] like Figures 7 and 8 As shown, in a specific embodiment, each wedge block 303 has a sliding slot 3042 in its inner cavity, and each sliding slot 3042 has a second sliding mechanism in its inner cavity. In this configuration, the opening position of the sliding slot 3042 is determined.

[0046] like Figures 8 and 9 As shown, the second sliding mechanism further includes two second sliding grooves 3031, which are respectively provided on opposite side walls of the sliding slot 3042. The two sliding slots 3042 are symmetrical with each other. Second sliders 3032 are slidably mounted in the two second sliding grooves 3031. The two second sliders 3032 are symmetrical with each other. The inclined plate 304 is fixedly connected to the opposite side walls of the two second sliders 3032. A return spring 3033 is provided in the inner cavity of each second sliding groove 3031, and the two ends of the return spring 3033 are respectively fixedly connected to the opposite side walls of the second slider 3032 and the second sliding groove 3031. In this configuration, the installation position of the second sliding mechanism is determined.

[0047] Example 3:

[0048] The difference between the above embodiment and this embodiment is that: Figures 3 to 8 As shown, a simulation device for advanced geological prediction and detection of unfavorable geological bodies in tunnels is shown. Each inclined plate 304 movably extends through a side wall of a collection box 305. A movable rod 3041 is movably mounted on one end of each inclined plate 304, distal from the rectangular mounting tube 301. A sealing plate 3053 is movably mounted on the other end of each movable rod 3041. This arrangement ensures that when the inclined plates 304 move horizontally, the movable rod 3041 can drive the sealing plate 3053 to open with the assistance of the rectangular block 3054 and the sliding rod 3055. Because the collection box 305 is in a rotating and moving state, it can collect soil and other substances from the inner wall of the tunnel opening.

[0049] like Figures 3 to 8 As shown, in a specific embodiment, each sealing plate 3053 is slidably mounted on the inner wall of the collection box 305. Four rectangular blocks 3054 are fixedly connected to one side of each sealing plate 3053. Each rectangular block 3054 is symmetrical to each other. Sliding rods 3055 movably extend between each rectangular block 3054. Each sliding rod 3055 is fixedly connected to the inner wall of the collection box 305 at both ends. Handle grooves 3056 are defined on opposite side walls of each sealing plate 3053. This arrangement ensures that the sealing plates 3053 can move horizontally.

[0050] The implementation principle of the simulation device for advanced geological prediction detection of unfavorable geological bodies in tunnels in this embodiment is as follows:

[0051] First, the worker moves the installation unit 100 so that the drill bit 1021 installed on the installation unit 100 can fit into the tunnel wall. When the fit is achieved, the worker starts the servo motor 201. When the servo motor 201 is running, it can drive the threaded rod 2011 to rotate. When the threaded rod 2011 rotates, it can drive the threaded sleeve 2012 to move horizontally with the assistance of the guide rod 2013.

[0052] At the same time, when the threaded rod 2011 rotates, it will be able to drive the circular fixing plate 202 to rotate. When the circular fixing plate 202 rotates, the circular fixing plate 202 will be able to drive the circular sleeve 2021 to rotate, so that the rectangular plug-in rod 2025 can be driven to rotate through the circular sleeve 2021. Because the end of the rectangular plug-in rod 2025 away from the circular sleeve 2021 is fixedly connected to the circular mounting plate 203, and the circular mounting plate 203 is provided with a circular slide groove 2031, and the inner cavity of the circular slide groove 2031 is slidably installed with two mutually symmetrical guide sliders 2032, and the end of the guide slider 2032 away from the circular slide groove 2031 is fixedly connected to the connecting rod 2034, and the other end of the connecting rod 2034 is fixedly connected to the threaded sleeve 2012, so that the circular mounting plate 203 can rotate and move horizontally at the same time;

[0053] Because a rectangular mounting tube 301 is fixedly mounted on one side wall of the circular mounting plate 203, and a drill bit 1021 is fixedly mounted on the rectangular mounting tube 301, the drill bit 1021 can be used to drill a hole in the tunnel wall. Because a positioning rod 302 is provided in the inner cavity of the rectangular mounting tube 301, and the other end of the positioning rod 302 is fixedly connected to the inner wall of the circular sleeve 2021, when the circular mounting plate 203 moves, the rectangular mounting tube 301 can be driven to move. However, at this time, the positioning rod 302 is stationary, and because The fixing block 3021 is fixedly mounted on the positioning rod 302, so that the side wall of the fixing block 3021 can be pressed against the wedge block 303, so that the wedge block 303 can move outward, thereby allowing the wedge block 303 to drive the collection box 305 to fit against the tunnel wall after the hole is opened. At this time, the fixing block 3021 will be able to press against the inclined plate 304 provided on the side wall of the wedge block 303, so that the inclined plate 304 can be forced to move horizontally with the assistance of the second slide groove 3031 and the second slider 3032;

[0054] When the inclined plate 304 moves horizontally, the sealing plate 3053 can be driven to open with the assistance of the rectangular block 3054 and the sliding rod 3055 through the movable rod 3041. Since the collecting box 305 is in a rotating and moving state, the soil and the like in the inner wall of the tunnel opening can be collected.
