Description

Technical Field

[0001] This application relates to the field of geological prediction technology, and in particular to a tunnel advanced geological prediction device. Background Technology

[0002] With the rapid development of infrastructure construction in my country, an increasing number of tunnel engineering projects under complex geological conditions are emerging. In order to ensure the safety and efficiency of tunnel construction, advanced geological forecasting has become an essential and crucial link.

[0003] The patent with publication number CN214997625U, concerning a tunnel advanced geological prediction device, addresses the issues of sample easy falling and limited water-blocking effect raised in the background technology. The proposed solution includes a sampling cylinder and a sleeve. The sampling cylinder has a sampling mechanism on its inner wall, comprising a first semi-circular sampling plate mounted on the bottom outer wall of the sampling cylinder, a rotating column rotatably connected to the top outer wall of the first semi-circular sampling plate, and a second semi-circular sampling plate mounted on the bottom outer wall of the rotating column. When the first and second semi-circular sampling plates in the sampling mechanism close the bottom of the sampling cylinder, this invention prevents the sample in the sampling chamber from falling out during the removal of the sampling cylinder from the sleeve. After sampling, the two semi-circular waterproof plates re-adhere to each other under the action of a spring in the waterproofing mechanism, effectively preventing water leakage and providing good waterproofing.

[0004] When the above devices are implemented, the height of the sampling tube is not easy to be automatically adjusted in a timely manner, which leads to slow sampling efficiency when sampling in different terrain environments and makes it impossible to extract samples in a timely and effective manner. Therefore, this application proposes a tunnel advanced geological prediction device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this application adopts the following technical solution: a tunnel advanced geological prediction device, including a sampling cylinder and a bottom pipe. A water pipe is installed on the inner wall of the sampling cylinder, and a rotating column is rotatably installed on the inner wall of the sampling cylinder.

The slider is slidably connected to the inner wall of a frame. A motor is fixedly installed on the top of the frame, and a lead screw is fixedly connected to the power output shaft of the motor.

[0007] In a preferred embodiment, the top of the rotating column is provided with a pentagonal hole, a pentagonal column is inserted into the inner wall of the pentagonal hole, and a handle is fixedly installed on the top of the pentagonal column.

[0008] By adopting the above technical solution, the handle can improve the convenience for users when rotating the rotating column, and the handle can be removed at will after rotation, thereby preventing others from rotating the rotating column at will.

[0009] In a preferred embodiment, the lead screw is threaded to the inner wall of the slider, and two limiting rods are symmetrically fixedly installed on the inner wall of the frame, with the slider slidably connected to the outer edges of the two limiting rods.

[0010] By adopting the above technical solution, the rotation of the lead screw can drive the slider to move up and down stably on the inner wall of the frame. The lead screw can be limited by the setting limit rod when it rotates, thereby ensuring the stable up and down movement of the slider.

[0011] In a preferred embodiment, the limiting block is slidably connected to the inner wall of the second frame, and a vertical rod is fixedly installed on the inner wall of the second frame. The limiting block is slidably installed on the inner wall of the second frame.

[0012] By adopting the above technical solution, the side of the fixing plate away from the frame can be limited, ensuring that both sides can move up and down synchronously and stably, thereby moving the bottom of the sampling tube to different positions.

[0013] In a preferred embodiment, side plates are fixedly installed on the outer sides of both frame one and frame two, and pins are slidably connected to the inner walls of the side plates, with a striking plate fixedly installed on the top of the pins.

[0014] By adopting the above technical solution, the pin can be inserted into the soil by striking the striking plate with a hammer, which can then be used to position frame one and frame two, ensuring their stability when installed in the tunnel for geological prediction.

[0015] In a preferred embodiment, a positioning ring is fixedly installed at the inner bottom of the frame, and the bottom end of the lead screw is rotatably connected to the inner wall of the positioning ring.

[0016] By adopting the above technical solution, the lead screw can be positioned during rotation, ensuring its stability during rotation, ensuring that it can rotate stably in a vertical state for a long time, and ensuring that it will not easily shift or wobble during rotation.

[0017] In a preferred embodiment, the sampling tube is slidably disposed on the inner wall of the sampling tube, and the inner diameter of the bottom tube is adapted to the outer diameter of the sampling tube.

[0018] By adopting the above technical solution, the sampling cylinder can be stably moved up and down on the inner wall of the bottom tube, realizing the adjustment of different positions of the bottom of the sampling cylinder, and there will be no gap when the sampling cylinder moves on the inner wall of the bottom tube.

[0019] The beneficial effects of this application are:

[0020] 1. This tunnel advanced geological prediction device uses a drive motor to rotate a lead screw, which in turn moves a slider downwards along the inner wall of frame one. This, in turn, moves the fixing plate and sampling tube downwards, allowing the bottom of the sampling tube to be moved to different positions for sampling, thus improving its practicality. Furthermore, striking the striking plate inserts the pin into the soil, which in turn positions frame one and frame two, ensuring their stability when installed in the tunnel for geological prediction.

[0021] 2. This tunnel advanced geological prediction device improves the user's convenience when rotating the rotating column by setting a handle, and the handle can be removed at will after rotation, thereby preventing others from rotating the rotating column at will. Attached Figure Description

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-4 The tunnel advanced geological prediction device includes a sampling cylinder 1 and a bottom pipe 2. A water pipe 3 is installed on the inner wall of the sampling cylinder 1. A rotating column 4 is rotatably installed on the inner wall of the sampling cylinder 1. A fixing plate 8 is fixedly installed on the outer edge of the sampling cylinder 1. A slider 12 and a limiting block 17 are fixedly installed on both sides of the fixing plate 8 respectively. The slider 12 is slidably connected to the inner wall of the frame 9. A motor 10 is fixedly installed on the top of the frame 9. A lead screw 11 is fixedly connected to the power output shaft of the motor 10.

[0029] See Figure 4 The top of the rotating column 4 is provided with a pentagonal hole 5, and a pentagonal column 6 is inserted into the inner wall of the pentagonal hole 5. A handle 7 is fixedly installed on the top of the pentagonal column 6, so that the user can improve the convenience of rotating the rotating column 4 by using the handle 7, and the handle 7 can be removed at will after rotation, thereby preventing others from rotating the rotating column 4 at will.

[0030] See Figure 3 The lead screw 11 is threaded to the inner wall of the slider 12. Two limit rods 13 are symmetrically fixedly installed on the inner wall of the frame 9. The slider 12 is slidably connected to the outer edge of the two limit rods 13, so that the rotation of the lead screw 11 can drive the slider 12 to move up and down stably on the inner wall of the frame 9. The lead screw 11 can be limited by the rotation of the limit rods 13, thereby ensuring the stable up and down movement of the slider 12.

[0031] See Figure 1 - Figure 3 The limiting block 17 is slidably connected to the inner wall of the frame 2 15. The inner wall of the frame 2 15 is fixedly installed with the upright 16. The limiting block 17 is slidably installed on the inner wall of the frame 2 15, so that the side of the fixing plate 8 away from the frame 1 9 can be limited, ensuring that both sides can move up and down synchronously and stably, thereby moving the bottom of the sampling tube 1 to different positions.

[0032] See Figure 1 and Figure 2 Side plates 18 are fixedly installed on the outer sides of both frame 19 and frame 2 15. Pins 19 are slidably connected to the inner walls of the side plates 18. A striking plate 20 is fixedly installed on the top of the pins 19, so that the pins 19 can be inserted into the soil by striking the striking plate 20 with a hammer. This can help to position frame 19 and frame 2 15 and ensure their stability when installed in the tunnel for geological prediction.

[0033] See Figure 3 A positioning ring 14 is fixedly installed on the inner bottom of the frame 9. The bottom end of the lead screw 11 is rotatably connected to the inner wall of the positioning ring 14, so that the lead screw 11 can be positioned during rotation, ensuring the stability of the lead screw 11 during rotation, ensuring that it can rotate stably in a vertical state for a long time, and ensuring that it will not easily shift or swing in position during rotation.

[0034] See Figure 1 The sampling tube 1 is slidably disposed on the inner wall of the sampling tube 1. The inner wall diameter of the bottom tube 2 is adapted to the outer edge diameter of the sampling tube 1, so that the sampling tube 1 can be stably moved up and down on the inner wall of the bottom tube 2, realizing the adjustment of different positions of the bottom of the sampling tube 1, and there will be no gap when the sampling tube 1 moves on the inner wall of the bottom tube 2.

[0035] Working principle: When using this device, firstly, a hammer can be used to strike the striking plate 20 to insert the pin 19 into the soil, which can then position the frame 9 and the second frame 15, ensuring their stability when installed in the tunnel for geological prediction. Then, the handle 7 can be used to improve the user's convenience when rotating the rotating column 4, and the handle 7 can be removed at will after rotation, thus preventing others from rotating the rotating column 4 at will. At the same time, the motor 10 can be driven to drive the lead screw 11 to rotate, which can then drive the slider 12 to move downward on the inner wall of the first frame 9, which can then drive the fixing plate 8 and the sampling cylinder 1 to move downward, thus moving the bottom of the sampling cylinder 1 to different positions for sampling, improving practicality.
