Detailed Description of the Embodiment

[0016] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0017] As Figures 1-3 shown, a tunnel vibration detection device includes a main rod 1. On both sides of the top of the main rod 1, handles 2 are installed. On one side of the handle 2, a first limiting piece 3 is installed, and on the other side of the handle 2, a second limiting piece 4 is installed.

[0018] At the bottom of the main rod 1, a conical drill bit 5 is installed. A cavity is provided inside the main rod 1, and a vibration monitoring sensor 6 is installed inside the cavity. The front end of the cavity is connected to a guard plate 7 by bolts. A protection block 8 is provided at the top of the main rod 1. The vibration monitoring sensor is connected to a wire 9, and one end of the wire 9 penetrates through the protection block 8 and the protection component.

[0019] The protection component includes protective covers 10 provided on both sides of the top of the protection block 8. The lower side of the protective cover 10 is connected to the top of the protection block 8 by bolts. An arc-shaped notch is provided at the top of the protective cover 10. When the two protective covers 10 are joined together, a through hole for the wire 9 to pass through is exactly formed in the middle.

[0020] It should be noted that during the blasting construction of the tunnel, it is necessary to detect the vibration inside the tunnel. At this time, the operator can hold the handle 2 with both hands and cooperate with the conical drill bit 5 to drill the main rod 1 into the ground inside the tunnel, and use the vibration detection sensor 6 inside the cavity to detect and collect the vibration data generated during the blasting construction. At the same time, connect the wire 9 to the vibration meter body to obtain the vibration data.

[0021] A guard plate 7 is provided at the front end of the cavity. Opening the guard plate 7 facilitates the operator to maintain and repair the vibration detection sensor 6. Since the vibration detection environment is complex, the connection between the wire 9 of the detection device and the device is prone to be damaged by external impact, so two protective covers 10 are provided on the top of the protective block 8 to protect the wire 9 and increase the practicality of the device.

[0022] First limit pieces 3 and second limit pieces 4 are provided on both sides of the handle 2. At the same time, a hand guard 12 is rotatably connected to the bottom of the first limit piece 3 and the bottom of the second limit piece 4, which can protect the operator's hand when the device is drilled into the ground, and can also limit the position of the handle 2 to prevent the handle 2 from being embedded in the ground after the main rod 1 is drilled into the ground, resulting in the situation that it is not convenient to pull out the main rod 1. Preferably, a rubber anti-slip layer is sleeved on the outside of the handle 2.

[0023] Scales 11 are provided at the front end of the main rod 1 and the front end of the guard plate 7, which is convenient for observing the insertion depth of the main rod 1. A limit frame 13 is sleeved outside the vibration monitoring sensor, and the limit frame 13 is connected to the inside of the cavity through bolts.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
