Description

A device for repairing hollow areas in lightweight heavy-duty flooring Technical Field

[0001] This utility model relates to the field of building hollow detection technology, specifically a device for repairing hollow areas in lightweight heavy-duty flooring. Background Technology

[0002] In industrial plants, logistics warehouses, and other similar settings, lightweight heavy-duty flooring is widely used due to its high load-bearing capacity. However, it is highly susceptible to hollowing defects due to limitations in construction techniques, material properties, and environmental conditions. These defects not only damage the surface quality of the flooring but also weaken its structural performance: in hollow areas, stress concentration accelerates the peeling of the concrete layer, leading to a decrease in load-bearing capacity. This directly affects the stability of heavy equipment operation and the durability of the floor. Long-term hollowing can also trigger a chain reaction of crack expansion and water seepage erosion, significantly increasing maintenance costs and even creating potential structural safety hazards. Therefore, it is necessary to use hollowing inspection devices to assess the hollowing condition of the floor.

[0003] In existing technologies, existing hollow detection devices take a long time to rotate one full turn when tapping for hollow sounds, and their complex structure makes them prone to malfunction. Summary of the Invention

[0004] The purpose of this utility model is to provide a device for inspecting and repairing hollow areas in lightweight heavy-duty flooring, in order to solve the problem that existing hollow area detection devices in the background art require a long time to rotate one full turn when tapping hollow areas, and have a relatively complex structure, which makes them prone to failure.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for inspecting hollow areas in lightweight heavy-duty flooring, comprising two sets of limiting covers, wherein a quick-tapping component is provided on the inner side of the limiting cover, and the quick-tapping component is used to improve the efficiency of tapping to detect hollow areas; and an adjustment component is provided on the front and back of the right end of the limiting cover, and the adjustment component is used to adjust the angle to meet the needs of the staff.

[0006] The rapid striking assembly includes a drive shaft, and a rotating frame is mounted on the outside of the drive shaft. Four sets of support springs are provided on the inside of the rotating frame, and a sliding block is provided at the end of the support spring. Limiting slide posts are mounted on the front and back of the sliding block, and a guide frame is provided on the outside of the limiting slide posts. The guide frame is located on the front and back of the inner side of the limiting cover, and the guide frame is a comma-shaped arc frame.

[0007] The adjustment assembly includes an adjustment knob, and adjustment screws are provided at both ends of the adjustment knob. A positioning toothed sleeve is provided on the outer side of the adjustment screw, and a rotating toothed ring is provided on the outer side of the positioning toothed sleeve.

[0008] Preferably, gear boxes are installed on the front and back of the limiting cover, and two sets of meshing gears are provided inside the gear boxes. A drive shaft is provided on the inner side of the lower end of the gear box, and a rubber wheel is provided on the outer side of the end of the drive shaft.

[0009] Preferably, a welding plate is installed on the right side of the lower end of the limiting cover, and a caster wheel is installed on the bottom of the welding plate.

[0010] Preferably, the rotating frame has limiting grooves on its front and back sides, and the limiting grooves are located outside the limiting slide column. A connecting rod is installed on the outside of the sliding block, and a hollow hammer is installed at the end of the connecting rod.

[0011] Preferably, a set of acoustic waveform instruments is installed on the front of the limiting cover, and a control panel is provided on the front of the acoustic waveform instruments. Two sets of connecting lines are provided on the top of the acoustic waveform instruments, and vibration sensors are installed at the ends of the connecting lines.

[0013] Preferably, a welding sleeve is installed on the right side of the rotating gear ring, and an auxiliary handle is provided on the inner side of the welding sleeve.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model, by installing a quick-strike component, uses a drive shaft to drive the rotating frame to rotate and adjust. During the rotation, the limiting slide column will slide along the comma guide frame. During the sliding process, the sliding block will compress the support spring and control the hollow hammer to retract. When the limiting slide column slides to the bottom of the comma, the support spring will quickly push the sliding block and the hollow hammer to extend outward, thereby striking the ground for detection. The multiple sets of structures can effectively improve efficiency, and the simple structure can reduce the probability of failure.

[0016] Secondly, this utility model, by installing an adjustment component, addresses the limitation of existing hollow detection devices where the height of the push-pull handle is fixed and cannot be adjusted to meet the needs of different operators. By setting a fixing block, an installation position can be provided for the inner structure. By controlling the rotation of the adjustment knob, the adjustment screw with the opposite thread can be rotated, thereby pushing the positioning tooth sleeve outward. After outward, it will be embedded in the tooth groove on the inner side of the rotating tooth ring, thus achieving a locking effect. The angle of the auxiliary handle can be adjusted by rotating it to adapt to different needs. Attached Figure Description
