Description

Technical Field

[0001] The invention relates to the technical field of tunnel anchor cable monitoring, and in particular to a tunnel anchor cable drilling hole corrosion environment and cable body performance monitoring device. Background Art

[0002] During the construction of coal mine tunnels, anchor cables, as key supporting components, play an important role in resisting structural weight and external pressure. However, anchor cables are usually buried in complex environments that are not easily observed directly. Especially when they pass through corrosive soil or water, their boreholes and cable bodies are extremely susceptible to corrosion. Rust not only reduces the mechanical properties of the anchor cables, but may also lead to structural instability and safety hazards, such as anchor cable breakage or loosening, which in turn threatens the stability and safety of the entire structure.

[0003] The existing monitoring of the anchor cable environment and cable performance in tunnels usually relies on personnel to regularly drill holes and take samples of the soil around the anchor cables through a drill bit. At the same time, the anchor cables need to be docked with tension test devices in order to evaluate the performance of the anchor cables. Both the docking process and the drilling and sampling process are relatively cumbersome and require high operation intensity, which increases the labor intensity of the inspectors, resulting in low inspection efficiency and inconvenience.

[0004] Therefore, a tunnel anchor cable drilling corrosion environment and cable body performance monitoring device has been developed, which is convenient for drilling and sampling the anchor cable environment and evaluating the cable body performance, is simple to operate, reduces the labor intensity of inspection personnel, and improves inspection efficiency. Summary of the invention

[0019] 4. The present invention sleeves the installation tube on the hydraulic anchor drilling rig, and rotates the screw rod through the knob on the screw rod. Under the action of the thread, the screw rod moves toward the inside of the installation tube, driving the arc-shaped clamping blocks to approach each other and clamp and fix on the hydraulic anchor drilling rig, thereby achieving the effect of facilitating the installation and fixing of the device on the hydraulic anchor drilling rig and improving the convenience of use of the device.

[0020] 5. The present invention allows the top cone on the fixed disc to pass through multiple steel cables of the anchor cable, and then starts the electric push rod to shrink the telescopic end of the electric push rod, so that the first pressure rod moves backward, and the support block rotates open to squeeze the steel cables apart, thereby achieving the effect of being able to separate different steel cables in the anchor cable, facilitating the fixing of the anchor cable, simplifying the operation and saving manpower.

[0021] 6.

The front of the mounting cylinder (1) is rotatably connected to the annular pressing plate (26), the front outer side of the annular pressing plate (26) is connected to the rack (27), the front left side of the mounting cylinder (1) is rotatably connected to the space cam (29), the outer side of the space cam (29) is threadedly connected to the gear (28), the gear (28) is meshed with the rack (27), the front side of the fixed disc (3) is connected to the second pressing rod (30), and the mounting cylinder (1) is connected to the space cam (29). The rod (30) and the second pressure rod (30) are pressed and matched with the space cam (29), so that the second pressure rod (30) on the fixed disk (3) presses the space cam (29), so that the space cam (29) moves, and under the action of the thread, the gear (28) rotates, and then through the meshing movement of the gear (28) and the rack (27), the rack (27) rotates, driving the annular pressure plate (26) to rotate, so that the annular pressure plate (26) presses the arc clamping block (4).

9. A tunnel anchor cable drilling corrosion environment and cable body performance monitoring device according to claim 8, characterized in that: The invention also comprises a second mounting block (31), a clamping rod (32) and a first telescopic spring (33). The front sides of the upper and lower parts of the mounting tube (1) are both connected to the second mounting block (31). The clamping rod (32) is slidably connected to the second mounting block (31). The first telescopic spring (33) is connected between the clamping rod (32) and the second mounting block (31) connected thereto. The clamping rod (32) is clamped with the annular pressure plate (26). When the clamping rod (32) is pulled to slide outward on the second mounting block (31), the first telescopic spring (33) is squeezed and contracted, so that the clamping rod (32) is separated from the annular pressure plate (26).

10. A tunnel anchor cable drilling corrosion environment and cable body performance monitoring device according to claim 9, characterized in that: The invention also comprises an annular mounting block (34), a clamping plate (35) and a second telescopic spring (36). The lower side of the mounting tube (1) is connected to the annular mounting block (34). A plurality of clamping plates (35) are slidably connected to the annular mounting block (34). A second telescopic spring (36) is connected between each clamping plate (35) and the annular mounting block (34). When the fixed disc (3) is placed between the clamping plates (35) and the clamping plates (35) are released, the second telescopic spring (36) rebounds, driving the clamping plates (35) to clamp and fix the fixed disc (3).
