Embodiment Construction
[0039] The patent is now described in detail in conjunction with the accompanying drawings. The accompanying drawings are all schematic diagrams, and only illustrate the basic structure of the patent in a schematic manner.
[0040] figure 1 The basic composition of the device is shown. A self-adjusting supporting device for geological radar antenna is composed of three parts: supporting part, self-adjusting part and supporting part; the self-adjusting part is set at the bottom of the supporting part, and the supporting part is set at the self-adjusting part bottom of.
[0041] figure 2 A schematic diagram of the supporting part is shown. The supporting part includes a plate 1, a radar antenna 2, a bolt hole 3, and a supporting bracket 4; four plates 1 are welded to form an open rectangular structure, and the radar antenna 2 is installed in the middle of the rectangular structure. Bolt holes 3 are provided on the side of the body, and the bolts pass through the bolt holes 3 ...

The invention provides a geological radar antenna self-regulation strutting device, belonging to the tunnel detection equipment technical field, and comprises a bearing portion, a self-regulation portion and a strutting portion. The self-regulation portion is arranged on the bottom of the bearing portion; the strutting portion is arranged on the bottom of the self-regulation portion. An insulation plate is utilized to protect a radar antenna, which can fix and protect the radar antenna, and meanwhile exert no influence on normal work of the radar antenna. A hydraulic rod and a sensor are creatively utilized to automatically provide appropriate pressure for the radar antenna, thereby realizing radar antenna height automatic adjustment in measurement, guaranteeing measurement accuracy, reducing manual work, and guaranteeing measuring personnel safety. A contraction alarm device and a stretching alarm device are provided to protect the radar antenna and the hydraulic rod from being crushed. Six strutting rods in the strutting portion can adjust self heights, allowing the device to be suitable for tunnels of different heights. The geological radar antenna self-regulation strutting device is simple to install and operate, and convenient to use, and can reduce labor costs, and guarantee detection work normal operation.
Description
technical field [0001] The invention relates to a geological radar antenna self-adjusting support device, especially when the geological radar is used for tunnel secondary lining thickness detection, steel bar distribution detection, backfill density detection and cavity and other defect detection work, it can ensure that the radar antenna and the tunnel The invention relates to a self-adjusting support device in close contact with walls, which belongs to the technical field of tunnel detection equipment. Background technique [0002] In recent years, my country's tunnel technology has developed rapidly. In the quality inspection of tunnel engineering and the detection of cavities and other diseases, geological radar detectors are commonly used for detection. When geological radar detects on the construction site, it is necessary to ensure that the radar antenna is in close contact with the tunnel wall and slides to avoid contact. not close etc. When detecting the top wall o...
