Description

Technical Field

[0001] This utility model belongs to the field of building inspection technology, and in particular relates to a clamping device for a building exterior wall insulation layer inspection device. Background Technology

[0002] The building exterior wall insulation layer inspection device is mainly used to detect hollow areas, detachment, and adhesion defects in the insulation layer. The commonly used inspection equipment is an infrared thermal imager, which identifies hollow areas through temperature difference imaging, enabling rapid and non-destructive quality assessment of the insulation layer, effectively preventing safety hazards caused by detachment, and ensuring the structural safety and energy-saving performance of buildings. When inspecting special structures such as glass curtain walls and curved exterior walls (e.g., irregularly shaped buildings like stadiums), manual operation is not stable and continuous. Therefore, a mobile device is needed to hold the inspection device and continuously move it along a preset path for full coverage inspection. Because the mobile device in related technologies uses rigid grippers, it cannot adapt to the undulations of the corrugated plate of the inspection device, resulting in local gaps between the inspection probe and the wall surface, affecting the fit of the infrared thermal imaging and the radar wave coupling effect. While flexible clamping components (such as silicone suction cups) can fit curved surfaces, the elastic deformation of the material causes micro-displacement of the probe, leading to ultrasonic ranging distortion or tapping positioning deviation. Therefore, an additional visual compensation system is needed to correct the positional error. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A clamping device for a building exterior wall insulation layer testing device includes an adjustable support device, a buffer fixing structure, a mounting plate, two clamping structures, and multiple fastening mechanisms.

[0006] The two clamping structures are arranged symmetrically above and below each other, and the sides of the two clamping structures are detachably connected by multiple fastening mechanisms. The inner side of the clamping structure is used to cooperate with the handheld part of the detection device.

[0007] The top of the adjustable support device is connected to the clamping structure located on the bottom side through the buffer fixing structure, the bottom of the adjustable support device is connected to the mounting plate, and the mounting plate is connected to the moving part of the mobile device.

[0008] The clamping structure includes a rigid clamping seat, a flexible positioning component, and two fixing plates. The inner side of the rigid clamping seat is an open cavity structure. The flexible positioning component is disposed on the inner side of the rigid clamping seat. The two fixing plates are symmetrically disposed on the left and right sides of the rigid clamping seat.

[0009] The two rigid clamping seats are located on the same side of the fixing plates and are connected by a plurality of the fastening mechanisms.

[0010] Furthermore, both the left and right ends of the open cavity structure have rounded chamfers.

[0011] Furthermore, the flexible positioning component includes a plurality of strip rubber pads, which are arranged inside the rigid clamping seat.

[0012] Furthermore, the clamping structure also includes two limiting structures, which are symmetrically arranged at the front and rear ends of the rigid clamping seat. Each limiting structure includes a limiting baffle and two reinforcing ribs. The limiting baffle is integrally connected to the rigid clamping seat, and the two reinforcing ribs are symmetrically arranged at the connection between the limiting baffle and the rigid clamping seat. The limiting baffle of one of the limiting structures is provided with a slot that can cooperate with the handheld part of the detection device.

[0013] Furthermore, the buffer fixing structure includes a fixed base, two fixed support plates and multiple buffer components. The two fixed support plates are symmetrically arranged on both sides of the fixed base. Each fixed support plate is welded to the fixed base. The fixed base is located in the middle of the fixed support plates. Multiple buffer components are arranged on each fixed support plate. The buffer components are used to connect to the rigid clamping seat.

[0014] Furthermore, the buffer assembly includes a connecting screw, a locking nut, and a buffer sleeve. The connecting screw passes through the fixed support plate, the buffer sleeve is fitted onto the connecting screw, the buffer sleeve is located between the fixed support plate and the rigid clamping seat, and the locking nut is located at the bottom of the connecting screw.

[0015] Furthermore, the adjustable support device includes a lifting screw, a fixing nut, a rotating sleeve, and an adjusting sleeve. The top of the lifting screw is connected to the fixed base, and the bottom of the lifting screw is threadedly engaged with the adjusting sleeve. The bottom of the adjusting sleeve is rotatably connected to the rotating sleeve via a flange. The upper end face of the mounting plate is provided with a threaded groove, and the bottom of the rotating sleeve is threadedly engaged with the threaded groove. The outer wall of the adjusting sleeve is provided with multiple protrusions for adjustment, and the fixing nut is disposed on the lifting screw.

[0016] Furthermore, the fastening mechanism includes a fastening screw and two fastening nuts. The fastening screw passes through the two rigid clamping seats located on the same side of the fixing plate, and the two fastening nuts are symmetrically arranged on the fastening screw.

[0017] Compared with existing technologies, the clamping device of the building exterior wall insulation layer detection device described in this utility model has the following advantages:

[0018] 1. The rigid clamping seat provides a deformation-resistant support frame. Its open cavity structure, combined with the detachable strip rubber pads, forms an adaptive flexible contact interface, which not only eliminates the local stress concentration caused by surface tolerances in the handheld part, but also avoids hard impact damage from pure rigid clamping. The combination of limiting baffles and reinforcing ribs distributed on both sides of the clamping seat prevents the axial movement and circumferential sway of the detection device under complex moving conditions. Combined with the multi-stage vibration absorption mechanism of the buffer rubber sleeves distributed across the clamping layer, the vibration energy transmitted from the outside to the detection probe is attenuated.

[0019] 2. The fixed base and double-sided welded support plates form a high-strength load-bearing frame to ensure the absolute positional stability of the clamping base under moving impacts; while the array-distributed buffer components adopt a screw-through elastic design, which uses the viscoelastic internal friction characteristics of the buffer sleeve to convert the lateral vibration energy into molecular chain friction heat energy. At the same time, the pre-tightening force of the locking nut is used to precisely control the compression deformation rate of the sleeve, thereby suppressing the multi-frequency flutter of the detection probe caused by the sudden stop and obstacle crossing of the mobile device to a certain extent.

[0020] 3. The threaded bearing system consisting of the lifting screw and the adjusting sleeve enables fine-tuning of the stroke. Combined with the self-locking threaded groove engagement structure at the bottom of the rotating sleeve, the operator can simultaneously complete stepless and precise positioning of vertical height and horizontal tilt angle by simply flicking the protrusion with one finger.
