Description

Technical Field

[0001] The utility model relates to the technical field of tunnel exploration and detection, and particularly to an operation device for detecting the arc arch surface of a tunnel. Background Technique

[0002] With the construction and development of infrastructure such as high-speed railways, highways, and hydropower projects, the construction of tunnel projects in mountainous areas and karst areas has increased rapidly. The detection of the tunnel arc arch surface is an important part of tunnel detection. Through the detection data of the tunnel arc arch surface, the geological conditions (spatial position, geological environment, and structure) above the tunnel arc arch can be displayed, and the concrete thickness, internal bonding degree, etc. can be detected, which has important guiding significance for project construction, safety prediction, and geological exploration.

[0003] The traditional tunnel exploration and detection method relying on drilling technology has a great destructive effect on the overall lining concrete. Therefore, the use of ground penetrating radar detection method for tunnel exploration and detection has become one of the important detection methods today. Ground penetrating radar detection mainly uses the emission and reflection of electromagnetic waves to detect the target electrical interface. The pulsed electromagnetic wave is emitted into the medium and the reflected signal is received by the receiving antenna.

[0004] During the detection process of the tunnel arc arch surface, it is necessary to keep the ground penetrating radar antenna in close contact with different positions of the tunnel arc arch at all times. The traditional operation method mainly relies on manual lifting. The long-term lifting action has a high labor intensity, and the antenna is intermittently separated from the arc arch due to muscle fatigue during manual operation, resulting in incomplete radar detection data.

[0005] For example, in the "Auxiliary Device for Non-destructive Detection of Radar on Tunnel Wall Surface" with the patent publication number CN201707453U, by adjusting the strut of the parallelogram structure at the bottom of the support mechanism, the tray for placing the probe of the radar detection instrument is close to the top wall of the tunnel. By setting springs to absorb the uneven height difference of the tunnel wall surface, the engineering detection personnel on the ground or on the trolley can obtain the information of the probe of the radar detection instrument through the cable.

[0006] However, this existing technology is suitable for detecting fixed points on the wall surface or detecting on a continuous non-concave and convex plane; while there are many 3-5 cm convex platforms on the tunnel arc arch surface, and during the movement process, the convex platforms will affect and hinder the passage of the ground penetrating radar antenna. Content of the Utility Model

[0007] The purpose of the utility model is to provide an operation device for detecting the arc arch surface of a tunnel to solve the problems raised in the above background technique.

[0008] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] An operating equipment for detecting the arc surface of a tunnel, comprising a clamping box for accommodating a ground penetrating radar detector, and the bottom of the clamping box is connected with a hinge support through a pre-tightening spring;

[0010] Arc-shaped guiding members are arranged on the upper edges of the two opposite sides of the clamping box along the moving direction of the operating equipment;

[0011] The lower end of the hinge support is hinged to the lifting platform, and a telescopic rod is also connected between the hinge support and the lifting platform. The plane formed by the lifting platform, the telescopic rod and the hinge support is perpendicular to the moving direction of the operating equipment;

[0012] The lifting platform is installed at the telescopic end of the lifting mechanism facing upwards.

[0013] Preferably, a clamping mechanism for clamping the ground penetrating radar detector is arranged on the clamping box.

[0014] Preferably, the clamping mechanism comprises a clamping screw, a clamping plate and an elastic buffer block. The clamping screw is threadedly connected to the clamping box, the clamping plate is movably connected to one end of the clamping screw, and the elastic buffer block is arranged on the side of the clamping plate facing away from the clamping screw.

[0015] Preferably, there are two groups of the clamping mechanisms, and the two groups of the clamping mechanisms are vertically distributed.

[0016] Preferably, the lifting mechanism is installed on a translation mechanism, and the moving direction of the translation mechanism is perpendicular to the working moving direction of the operating equipment.

[0017] Preferably, a traveling vehicle is further included, and the operating equipment is installed on the traveling vehicle.

[0018] Preferably, the lifting mechanism is composed of a plurality of X-shaped rods connected movably.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] The present utility model clamps the ground penetrating radar detector through the clamping mechanism, and realizes the lifting, translation and deflection operation states of the ground penetrating radar detector at the end by adjusting the cooperation of the lifting mechanism, the translation mechanism and the telescopic rod.

[0021] Problems such as high operation risk and high labor intensity of workers caused by the special operation position of the ground penetrating radar antenna during the tunnel detection process can be solved;

[0022] During the traveling of the traveling vehicle, through the cooperation of the arc-shaped guiding member and the pre-tightening spring, it is convenient for the clamping box to cross a convex platform of 3-5 cm. It is beneficial to pass through and can effectively ensure the integrity of the data collection of the ground penetrating radar. Description of the Drawings

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] An operation equipment for tunnel arc surface detection, as Figures 1-3 shown, includes a translation mechanism 1, a lifting mechanism 2, a lifting platform 21, a telescopic rod 3, a clamping box 4, an arc guide 41, a hinge bracket 5, a pre-tightening spring 6, a clamping mechanism and a traveling vehicle.

[0032] The translation mechanism 1 can be installed on the traveling vehicle by a lead screw drive structure. The translation mechanism 1 is used to drive the lifting mechanism 2 above it to move horizontally in a straight line to achieve translation.

[0033] The lifting mechanism 2 is composed of multiple X-shaped rods connected movably. The lifting mechanism 2 is used to drive the lifting platform 21 to lift vertically.

[0034] The lower end of the hinge bracket 5 is hinged to the middle of the top surface of the lifting platform 21. The two ends of the telescopic rod 3 are respectively hinged to the edge of the lifting platform 21 and the edge of the hinge bracket 5. Thus, the telescopic movement of the telescopic rod 3 drives the hinge bracket 5 to rotate relative to the lifting platform 21.

[0035] Figure 1 and Figure 3 The arrow in it indicates the moving direction of the traveling vehicle.

[0036] A plurality of uniformly arranged pre-tightening springs 6 are connected between the top surface of the hinge support 5 and the bottom surface of the clamping box 4.

[0037] The clamping mechanism includes a clamping screw 7, a clamping plate 71 and an elastic buffer block (rubber block). The clamping screw 7 is threadedly connected to the clamping box 4. The clamping plate 71 is movably connected to one end of the clamping screw 7. The elastic buffer block is arranged on the side wall of the clamping plate 71 facing away from the clamping screw 7. Two groups of clamping mechanisms are provided and arranged perpendicular to each other.

[0038] Arc-shaped guides 41 are provided on the upper edges of the front and rear sides of the clamping box 4.

[0039] Working principle: Place the ground penetrating radar detector 100 in the clamping box 4. Rotate the clamping screw 7 so that one side of the clamping plate 71 with the elastic buffer block abuts against the ground penetrating radar detector 100. The ground penetrating radar detector 100 is fixed in the clamping box 4 by two mutually perpendicular clamping mechanisms.

[0040] The lifting mechanism 2 is lifted to realize the lifting of the ground penetrating radar detector 100 to adapt to operations at different heights. Since the cross-section of the tunnel arch surface is in an arc shape, the ground penetrating radar detector 100 is tilted and adjusted in angle by the telescopic movement of the telescopic rod 3 for adaptation. The translation mechanism 1 drives the ground penetrating radar detector 100 to move horizontally left and right to adjust the horizontal position.

[0041] Before use, the lifting structure 2 is raised so that the gap between the clamping box 4 and the tunnel arch surface reaches the set distance. The traveling vehicle drives the operating equipment to move along the length track of the tunnel arch surface. When encountering a convex platform of 3 - 5 cm, first, the arc-shaped guide 41 of the clamping box 4 abuts, and the convex platform of 3 - 5 cm is guided to cross through the arc-shaped surface of the arc-shaped guide 41. During this process, the pre-tightening spring 6 can elastically deform to compensate for the elastic lifting of the clamping box 4.

[0042] Embodiment 2: It includes all the contents of Embodiment 1, and the difference is that:

[0043] A plurality of rollers are installed on the top of the clamping box 4 to replace the abutment with the tunnel arch surface to achieve rolling cooperation. Before use, the lifting structure 2 is raised so that the rollers on the top of the clamping box 4 abut against the tunnel arch surface. The pre-tightening spring 6 is compressed by a small distance to generate a small reverse elastic force, and the distance between the ground penetrating radar detector 100 and the tunnel arch surface is ensured to be within the set range through the pre-tightening spring 6, avoiding errors caused by fluctuations in the distance between the tunnel arch surface and the ground.
