Thickness detection equipment is a special equipment used for highway thickness detection. Generally, multiple detections are required at multiple locations on a highway, so its detection efficiency and accuracy are very important.

[0003] Existing thickness detection equipment includes a base and a drilling device installed on the base. When in use, the base is placed at the corresponding detection position, and then the road surface is drilled by the drilling device, and the sample core is taken out to measure the size, thereby achieving thickness detection.

[0004] With regard to the above-mentioned related technologies, after the drilling is completed, it is necessary to manually remove the equipment from the drilling position, and then use tools to take out the sample core for measurement, which is cumbersome and inconvenient to use. Summary of the Invention

[0007] By adopting the above technical solution, when in use, the base is directly placed at the position to be inspected on the road, and the core drilling mechanism is started to drill the core of the road; then the first drive component is started to drive the support column to rotate until the mounting seat is directly above the core drilling position; the drive mechanism is started to drive the mounting seat to move vertically downward until the clamping plate is inserted into the gap between the sample core and the road; then the clamping plate is driven to rotate to clamp the sample core, so that the sample core can be removed from the road by driving the mounting seat to move vertically upward, and then the sample core can be measured; this process does not require moving the entire structure to complete the removal and accurate measurement of the sample core, thereby improving the overall convenience of the detection process.

[0008] Preferably, the driving mechanism includes a linkage seat and a pair of driving blocks, the linkage seat is located directly above the mounting seat, and a first elastic member is provided between the linkage seat and the mounting seat; the two driving blocks are respectively installed on opposite sides of the linkage seat, and the bottom end of the driving block is provided with a guide surface, and the top end of the clamping plate abuts against the guide surface; the driving mechanism also includes a second driving component and a locking component, the second driving component is used to drive the linkage seat to move in the vertical direction; when the driving block drives the clamping plate to rotate and clamp the sample core, the locking component is used to lock the position between the linkage seat and the mounting seat.

[0009] By adopting the above technical solution, when the sample core needs to be taken out, the second driving assembly is started to drive the linkage seat to move vertically downward. Due to the action of the first elastic member, the mounting seat is synchronously driven to move until the clamping plate is inserted into the gap between the sample core and the road, and the mounting seat abuts against the sample core; then the linkage seat is continued to be driven to move, the first elastic member is compressed, and the linkage seat is close to the mounting seat, so that the guide surface on the driving block drives the clamping plate to rotate, thereby clamping the sample core; finally, the position between the linkage seat and the mounting seat is locked by the locking assembly, and then the linkage seat is driven to move vertically upward, so that the sample core can be taken away from the road for measurement; in this process, it is only necessary to drive the linkage seat to move vertically downward to drive the clamping plate to clamp the sample core, which is not only efficient, but also requires less power source, low cost and high stability.

[0011] By adopting the above technical solution, when the mounting seat abuts against the sample core and continues to drive the linkage seat to move, the locking rod slides in the locking groove, and then the locking member locks the locking rod in the locking groove, thereby locking the position between the mounting seat and the linkage seat, preparing for the subsequent vertical upward movement of the two together.

[0013] By adopting the above technical solution, when the linkage seat moves toward the mounting seat, until the locking rod moves to the avoidance groove corresponding to the hole wall of the plug-in hole, the locking rod is driven to slide by the action of the second elastic member until the hole wall of the plug-in hole is stuck in the avoidance groove, so that the locking rod can be stabilized in the locking groove. In this process, the locking between the linkage seat and the mounting seat can be completed by driving the linkage seat to move vertically downward, thereby further improving the operating efficiency; when the lock needs to be released, it is only necessary to push the locking rod to slide so that the hole wall of the plug-in hole leaves the avoidance groove, and the linkage seat and the mounting seat can be reset by the action of the first elastic member, driving the block to leave the clamping plate, so that the clamping plate releases the restraint on the sample core; this process is still easy to operate.
