Description

Technical Field

[0001] The utility model relates to the technical field of tunnel geological detection equipment, in particular to a tunnel engineering geological radar detection device. Background Art

[0002] With the rapid development of tunnel engineering, high-precision detection and monitoring of geological environmental conditions during tunnel construction and operation has become a vital task. As an indispensable geophysical exploration method in modern tunnel engineering, tunnel geological radar detection technology is widely used in the detection of tunnel lining quality, steel bar distribution, changes in geological environmental conditions, and geological deformation after construction. However, the existing tunnel geological radar detection equipment still has certain limitations in the application process, which are specifically manifested in the following aspects:

[0003] First of all, the traditional tunnel geological radar detection equipment needs to be manually lifted by a pole to detect the inner wall of the tunnel. This detection method is not only time-consuming and labor-intensive, but also inefficient and difficult to meet the needs of fast and accurate detection of large-scale tunnel projects. At the same time, due to the need for manual operation, the accuracy and stability of the detection results are also affected to a certain extent.

[0004] Secondly, another detection method is to install detection equipment on the top of the vehicle and detect the top wall of the tunnel by slowly running the vehicle. Although this method improves the detection efficiency to a certain extent, it will interfere with the normal passage inside the tunnel and may even cause safety problems. Especially in busy traffic tunnels, this detection method will seriously affect the normal operation of the tunnel. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a tunnel engineering geological radar detection device to overcome the deficiencies in the above-mentioned prior art.

[0006] The utility model solves the above-mentioned technical problems with the following technical solutions: a tunnel engineering geological radar detection device, comprising a semi-annular guide rail, a sliding mechanism, and driving inline skates arranged vertically downward at both ends of the semi-annular guide rail; the sliding mechanism slides along the circumference direction of the semi-annular guide rail, and a geological detection radar is connected to the sliding mechanism; the driving inline skates drive the semi-annular guide rail to move along the length direction of the tunnel.

[0007] The beneficial effects of the utility model are as follows: the geological detection radar is attached to the inner wall of the tunnel by a semi-circular guide rail, and the semi-circular guide rail is driven by the inline skates to move forward along the tunnel, thereby driving the geological detection radar to move forward along the tunnel to detect the tunnel; this installation method will not affect the normal passage of the tunnel and has higher safety. In addition, during the detection process, the geological detection radar can maintain the detection at the same height of the tunnel according to the position of the sliding mechanism on the semi-circular guide rail. When the height detection is completed, the sliding mechanism slides along the semi-circular guide rail to adjust the position of the geological detection radar, so as to realize detection at different heights on the same section of the tunnel, making the detection more comprehensive and efficient.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the semi-annular guide rail is a gear guide rail, and the sliding mechanism includes a mounting plate, a drive motor and a gear. The drive motor is mounted on the mounting plate, a gear is arranged on the rotating shaft of the drive motor, and the gear is meshed with the semi-annular guide rail.

[0010] Furthermore, a slip ring is provided on one side of the semi-annular guide rail, and at least two pulleys are provided on the mounting plate, and the two pulleys are engaged with the slip ring.

[0011] Furthermore, driven inline skating wheels are respectively extended to both sides of the lower end of the semi-circular guide rail, and the driven inline skating wheels are against the inner wall of the tunnel.

[0012] Furthermore, an extension rod is rotatably connected to the sliding mechanism via a first hinge seat, and the geological detection radar is connected to the top end of the extension rod.

[0013] Furthermore, the top end of the extension rod is rotatably connected to the geological detection radar through a second hinged seat.

[0014] Furthermore, the rotating shafts of the first hinge seat and the second hinge seat are both provided with torsion springs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1 to Figure 3 As shown, Example 1, a tunnel engineering geological radar detection device, includes a semi-circular guide rail 1, a sliding mechanism 2 and driving inline skates 3 arranged vertically downward at both ends of the semi-circular guide rail 1; the sliding mechanism 2 slides along the circumference direction of the semi-circular guide rail 1, and a geological detection radar 4 is connected to the sliding mechanism 2; the driving inline skates 3 drive the semi-circular guide rail 1 to move along the length direction of the tunnel.

[0022] The geological detection radar 4 is attached to the inner wall of the tunnel through the semi-circular guide rail 1, and the semi-circular guide rail 1 is driven by the in-line skates 3 to move forward along the tunnel, thereby driving the geological detection radar 4 to move forward along the tunnel to detect the tunnel; this installation method will not affect the normal passage of the tunnel and has higher safety. In addition, during the detection process, the geological detection radar 4 can maintain the same height detection of the tunnel according to the position of the sliding mechanism 2 on the semi-circular guide rail 1. When the height detection is completed, the sliding mechanism 2 slides along the semi-circular guide rail 1 to adjust the position of the geological detection radar 4, so as to realize detection at different heights on the same section of the tunnel, making the detection more comprehensive and efficient.

[0023] In the specific implementation, an existing conventional geological detection radar 4 is used, such as the RD60 geological radar detector and the RTS2060 dual-frequency real-time sampling ground penetrating radar. The driving inline skates 3 are driven by a conventional existing motor. The driving inline skates 3 include a driving wheel, a plurality of driven wheels and a U-shaped wheel frame. The driving wheel and the driven wheel are arranged in a straight line in the U-shaped wheel frame, and the driving wheel is driven by a motor.

[0024] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0025] The semi-annular guide rail 1 is a gear guide rail, and the sliding mechanism 2 includes a mounting plate 21, a driving motor 22 and a gear 23. The driving motor 22 is mounted on the mounting plate 21, and a gear 23 is provided on the rotating shaft of the driving motor 22, and the gear 23 is meshed with the semi-annular guide rail 1.

This can prevent the semi-circular guide rail 1 from shaking relative to the inner wall of the tunnel during the forward movement of the semi-circular guide rail 1 along the tunnel, thereby ensuring that when the position of the sliding mechanism 2 on the semi-circular guide rail 1 is fixed, the geological detection radar 4 detects the same height of the tunnel.
