Description

Technical Field

[0001] This utility model relates to the field of wall inspection, and in particular to a device for inspecting the quality of building exterior surfaces. Background Technology

[0002] Exterior wall leakage is a common and difficult-to-detect quality defect during construction. If the finishing layer has hollow areas, cracks, or poor adhesion, it can cause tiles, stone, or paint layers to detach, threatening pedestrian safety and the building's integrity. Defects in the finishing layer may mask internal structural problems, such as wall cracks or water seepage corroding reinforcing steel. Timely inspection is crucial to identify potential risks early. Severe exterior wall leakage significantly impacts the homeowner's use of the property, and the resulting repairs can incur substantial economic losses. Therefore, a comprehensive leakage inspection of the exterior walls is necessary before the building's final acceptance inspection.

[0003] The current common inspection method is to manually use a hollow hammer to inspect the wall surface. When inspecting the exterior wall surface, it is necessary to rent expensive outdoor climbing equipment, and then manually stand on the climbing equipment to use the hollow hammer to inspect the wall surface. This is difficult to operate and costly.

[0004] The principle behind infrared camera defect detection is primarily based on the differences in thermal radiation characteristics of an object's surface. By capturing and analyzing infrared radiation, anomalies in materials or structures can be identified. Defects within materials, such as cracks, delamination, and voids, alter local heat conduction or heat capacity, leading to uneven surface temperature distribution. These differences are captured by infrared cameras.

[0005] Therefore, a new type of building exterior surface quality inspection device can be designed based on the functions of infrared cameras. Utility Model Content

[0006] Therefore, it is necessary to propose a new quality inspection device for building exterior surfaces, which addresses the problems of existing building exterior surface quality inspection devices requiring manual inspection, resulting in high construction difficulty and cost.

[0007] A building exterior finish quality inspection device includes a mounting base and a lifting bracket. The lower end of the lifting bracket is fixed to the mounting base, and the upper end of the lifting bracket is provided with an electric lifting device. The electric lifting device includes a mounting plate and an electric winch. The lower end of the winch rope is connected to a sliding support assembly, and an infrared detection device is provided on the sliding support assembly.

[0008] As one embodiment of this utility model, the lower end of the above-mentioned mounting base is provided with multiple fixing plates, and each fixing plate is fixed to the building by screws.

[0009] As one embodiment of the present invention, the electric winch includes a drive motor and a winch. The winch is driven by the drive motor to rotate. The winch rope is wound on the winch, and a buckle is connected to the lower end of the winch rope.

[0010] As one embodiment of the present invention, the above-mentioned sliding support assembly includes a sliding support plate, and the sliding support plate is provided with a plurality of pulleys in the circumferential direction.

[0011] As one embodiment of this utility model, a connecting plate is provided on the outer side of the sliding support plate, and a connecting hole is provided on the connecting plate for engaging with a buckle.

[0012] As one embodiment of the present invention, the infrared detection device is fixed at the lower end of the sliding support plate, and the infrared detection device includes a horizontal moving device, a vertical moving device, and an infrared measuring camera.

[0013] As one embodiment of the present invention, the above-mentioned lateral moving device includes a base connecting plate and a slide rail and a slider that slide against each other. The slide rail is fixed on the base connecting plate, the longitudinal moving device is disposed on the slider, and a lateral pushing rod is disposed on the base connecting plate. The end of the lateral pushing rod is fixed on the longitudinal moving device.

[0014] As one embodiment of the present invention, the longitudinal moving device includes a longitudinal base plate and a longitudinal electric cylinder. The longitudinal base plate is fixed on the slider. A camera mounting plate is provided on the telescopic rod of the longitudinal electric cylinder. The infrared measuring camera is fixed on the camera mounting plate.

[0015] As one embodiment of this utility model, a limit block is provided at one end of the slide rail. Technical advantages of this utility model:

[0016] 1. The electric lifting device uses an electric winch to drive the rope, thereby raising and lowering the sliding support assembly. The drive motor drives the winch to rotate, allowing the rope to be wound and released freely. The detection position of the infrared detection device can be adjusted according to the needs of the building exterior at different heights, meeting the detection requirements of different building heights and greatly improving the applicability and flexibility of the device.

[0017] 2. The infrared detection device is fixed to the lower end of the sliding support plate and has a lateral movement device and a longitudinal movement device. The lateral movement device pushes the longitudinal movement device along the slide rail via a lateral push rod. The longitudinal movement device drives the camera mounting plate and the infrared measuring camera to move up and down via a longitudinal electric cylinder, enabling the infrared measuring camera to move freely in both horizontal and vertical directions. This allows for comprehensive and blind-spot-free detection of the building's exterior surface, effectively improving the accuracy and completeness of the detection. Attached Figure Description

Detailed Implementation

[0027] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0028] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] Specific embodiments of this utility model are as follows: Figures 1 to 7 As shown, this utility model provides a building exterior surface quality inspection device that can detect defects in the exterior surface of walls, solving the problems of existing building exterior surface quality inspection devices requiring manual inspection, which are difficult to construct and costly.

[0031] like Figure 1-2 As shown,

[0032] A building exterior surface quality inspection device includes a mounting base 1 and a lifting bracket 2. The lower end of the lifting bracket 2 is fixed on the mounting base 1, and the upper end of the lifting bracket 2 is provided with an electric lifting device 3. The electric lifting device 3 includes a mounting plate 31 and an electric winch 32. The lower end of the winch rope 320 of the electric winch 32 is connected to a sliding support assembly 4, and an infrared detection device 5 is provided on the sliding support assembly 4.

[0033] Combination Figure 1-2 The building exterior surface quality inspection device mainly consists of an installation base 1, a lifting bracket 2, an electric lifting device 3, a sliding support assembly 4, and an infrared detection device 5. These parts work together to inspect the quality of the building exterior surface.

[0034] The lower end of the mounting base 1 is provided with multiple fixing plates 11, each fixing plate 11 being fixed to the building with screws. The mounting base 1 serves as the basic support structure for the entire device, and its lower end is provided with multiple fixing plates 11. During installation, each fixing plate 11 is securely fixed to the building with screws.

[0035] The lifting support 2 is a square frame made of welded pipes. The lower end of the lifting support 2 is fixed on the mounting base 1. Through the mounting base 1, the lifting support 2 can stand vertically on the exterior of the building.

[0036] like Figures 2-3 As shown, the electric lifting device 3 is installed on the upper end of the lifting support 2, including a mounting plate 31 and an electric winch 32. The mounting plate 31 serves to fix and support the electric winch 32, stably installing the electric winch 32 on the upper end of the lifting support 2, ensuring the stability of the electric winch 32 during operation.

[0037] The electric winch 32 includes a drive motor 321 and a winch 322. The winch 322 is driven by the drive motor 321 to rotate. The winch rope 320 is wound on the winch 322, and the lower end of the winch rope 320 is connected to a buckle 323.

[0038] like Figures 3-4 As shown, the drive motor 321 provides power for the rotation of the winch 322, which rotates under the drive of the motor 321. The winch rope 320 is wound around the winch 322, and a buckle 323 is connected to the lower end of the rope 320. When the drive motor 321 starts, it drives the winch 322 to rotate, thereby enabling the winding and unwinding of the rope 320, and thus controlling the lifting and lowering of the sliding support assembly 4. The electric lifting device drives the rope through the electric winch, realizing the lifting and lowering of the sliding support assembly. The drive motor drives the winch to rotate, allowing the rope to be wound and unwinded freely. This allows the detection position of the infrared detection device to be adjusted according to the needs of different building exterior facades, meeting the detection requirements of different building heights and greatly improving the applicability and flexibility of the device.

[0039] like Figures 4-5 As shown, the sliding support assembly 4 includes a sliding support plate 41, and four pulleys 42 are arranged in the circumferential direction of the sliding support plate 41. The function of the pulleys 42 is to reduce the friction between the sliding support assembly 4 and the exterior wall surface during the movement of the sliding support assembly 4, so that the sliding support assembly 4 can move more smoothly and avoid causing additional damage to the exterior wall surface during the up and down movement throughout the inspection process.

[0040] A connecting plate 43 is provided on the outer side of the sliding support plate 41. The connecting plate 43 is provided with a connecting hole 44, which is used to engage with the buckle 323. The sliding support assembly 4 is connected to the electric lifting device 3 through the buckle 323 at the lower end of the rope 320.

[0041] The connecting hole 44 is used to engage with the buckle 323 at the lower end of the electric winch 32 rope 320. Through this engagement method, a reliable connection between the sliding support assembly 4 and the electric lifting device 3 is achieved, so that the electric lifting device 3 can drive the sliding support assembly 4 to rise and fall by controlling the winding and unwinding of the rope 320.

[0042] like Figures 5-7 As shown, the infrared detection device 5 is fixed to the lower end of the sliding support plate 41. The infrared detection device 5 includes a lateral movement device 51, a longitudinal movement device 52, and an infrared measuring camera 53. The infrared detection device 5 is fixed to the lower end of the sliding support plate 41 and is used to inspect the quality of the building's exterior surface.

[0043] The lateral moving device 51 includes a base connecting plate 510 and a slide rail 511 and a slider 512 that slide against each other. The slide rail 511 is fixed on the base connecting plate 510. The longitudinal moving device 52 is mounted on the slider 512. A lateral pushing rod 513 is mounted on the base connecting plate 510, and the end of the lateral pushing rod 513 is fixed to the longitudinal moving device 52. The base connecting plate 510 serves as the mounting base for the lateral moving device 51 and is used to connect it to the sliding support plate 41. The slide rail 511 is fixed on the base connecting plate 510.

[0044] The slide rail 511 and the slider 512 slide against each other, and the longitudinal moving device 52 is mounted on the slider 512. In this way, the slider 512 can slide horizontally on the slide rail 511, thereby driving the longitudinal moving device 52 and the infrared measuring camera 53 to move in the horizontal direction.

[0045] The end of the lateral push rod 513 is fixed to the longitudinal moving device 52. When the lateral push rod 513 extends or retracts, it can push the longitudinal moving device 52 and the slider 512 to slide on the slide rail 511, thereby realizing the horizontal movement of the infrared measuring camera 53.

[0046] A limit block 514 is provided at one end of the slide rail 511 to limit the sliding range of the slider 512 and prevent the slider 512 from sliding out of the slide rail 511.

[0047] The longitudinal moving device 52 includes a longitudinal base plate 521 and a longitudinal electric cylinder 522. The longitudinal base plate 521 is fixed on the slider 512. A camera mounting plate 523 is provided on the telescopic rod of the longitudinal electric cylinder 522, and an infrared measuring camera 53 is fixed on the camera mounting plate 523.

[0048] The longitudinal base plate 521 is fixed on the slider 512 and moves as the slider 512 moves in the horizontal direction.

[0049] A longitudinal electric cylinder 522 is mounted on a longitudinal base plate 521, and a camera mounting plate 523 is provided on the telescopic rod of the longitudinal electric cylinder 522. When the telescopic rod of the longitudinal electric cylinder 522 extends or retracts, it can drive the camera mounting plate 523 and the infrared measuring camera 53 fixed on the camera mounting plate 523 to move in the vertical direction.

[0050] The infrared measuring camera 53 is fixed on the camera mounting plate 523. Through the coordinated action of the horizontal moving device 51 and the vertical moving device 52, the infrared measuring camera 53 can move in the horizontal and vertical directions, thereby conducting comprehensive quality inspections on different locations of the building's exterior surface.

[0051] The infrared detection device is fixed to the lower end of the sliding support plate and has a lateral movement device and a longitudinal movement device. The lateral movement device pushes the longitudinal movement device along the slide rail via a lateral push rod. The longitudinal movement device drives the camera mounting plate and the infrared measuring camera to move up and down via a longitudinal electric cylinder, enabling the infrared measuring camera to move freely in both horizontal and vertical directions. This allows for comprehensive and blind-spot-free detection of the building's exterior surface, effectively improving the accuracy and completeness of the detection.

[0052] III. Work Process

[0053] In practical use, the mounting base 1 is first fixed to the building using the fixing plate 11 and screws. Then, the drive motor 321 of the electric lifting device 3 is started to control the winding and unwinding of the winch 320, moving the sliding support assembly 4 to a suitable height. Next, the position of the infrared measuring camera 53 is adjusted by the coordinated action of the lateral pushing pole 513 and the longitudinal electric cylinder 522, aligning it with the area to be inspected on the building's exterior surface. The infrared measuring camera 53 scans and inspects the building's exterior surface, acquiring relevant quality data. After completing the inspection of one area, the position of the infrared measuring camera 53 is adjusted again by the lateral moving device 51 and the longitudinal moving device 52 to inspect the next area, until the quality inspection of the entire building's exterior surface is completed.

[0054] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
