Description

Technical Field

[0001] The utility model relates to the technical field of road void detection, in particular to a mechanical vibration source for road void detection. Background Technique

[0002] Road void detection refers to the process of using various technical means to detect and evaluate the voids, loose or falling-off areas existing in the road base or the underlying soil mass. These void areas may cause structural damage to the road, thereby affecting the smoothness and bearing capacity of the road, and may even lead to safety accidents such as road collapse.

[0003] Therefore, it is necessary to regularly detect the road to avoid road collapse caused by void areas. However, at present, the detection of road void areas still relies on manually holding tools to hammer the road. As the main component of road detection, the vibration source requires the consistency of energy and frequency. However, the force of manual hammering is not uniform, resulting in inaccurate and slow detection. Therefore, a mechanical vibration source for road void detection is proposed. Content of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A mechanical vibration source for road void detection, including a rectangular bottom plate, a support plate is fixedly connected to the top of the bottom plate, a rectangular plate is fixedly connected to one side of the support plate, a rectangular block is fixedly connected to one side of the support plate, a circular chute is opened on the rectangular block, a circular hole is opened on the bottom plate, a sliding rod is slidably connected in the circular chute, several transmission teeth are fixedly connected to one side of the sliding rod, a first transmission rod is fixedly connected to one side of the sliding rod, a limiting block is fixedly connected to the top of the sliding rod, an impact block is fixedly connected to the bottom of the sliding rod, a circular cavity is opened inside the impact block, a mechanical vibration source body is installed in the circular cavity, and the impact block is located directly above the circular hole.

[0008] Preferably, one side of the support plate is fixedly connected with an L-shaped plate, one side of the L-shaped plate is fixedly connected with a handle, and universal wheels are installed at the bottom of the support plate.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] When this device is in use, the rotating rod can be driven to rotate by the driving motor, the rotating rod drives the toothless gear to rotate, the toothless gear drives the transmission tooth to move upward, the transmission tooth drives the sliding rod to slide upward in the circular chute. When it rotates to the side where the toothless gear has no teeth, the sliding rod falls along the circular chute, and the impact block impacts the ground through the circular hole.

The toothed side of the toothless gear 15 continues to drive the transmission tooth 8 to move upward, repeating the previous steps to continue the impact detection.

[0027] Meanwhile, the specific model and specification of the drive motor 13 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.
