Description

Technical Field

[0001] This invention relates to the field of building envelope system testing technology, and is particularly applicable to the testing of exterior maintenance systems for high-rise and super high-rise buildings. Background Technology

[0002] As a crucial component of building structures, building envelope systems are prone to aging and damage with age, directly threatening residents' lives and property, increasing government governance costs, and ultimately hindering urban renewal and sustainable development. Therefore, conducting safety inspections of building envelope systems has become an urgent need to ensure urban operational safety and advance urban renewal efforts.

[0003] Currently, inspection technologies for building envelope systems can be broadly categorized into traditional on-site inspection technologies and emerging technologies. Traditional on-site inspection technologies include visual inspection, light hammer tapping, measurement, instrument measurement, and on-site pull-out tests; emerging technologies encompass terahertz detection, laser detection, ultrasonic detection, electromagnetic induction detection, and infrared thermal imaging detection. However, all of these methods have significant limitations when applied to the inspection of high-rise and super high-rise buildings. They not only fail to meet the representativeness requirements of random sampling but also require inspectors to operate from suspended platforms, posing extremely high safety risks. Meanwhile, despite the rapid development of the low-altitude economy and the emergence of drone inspection as a new solution, restrictions imposed by urban no-fly zones prevent drones from covering all inspection scenarios and meeting the needs of comprehensive inspection.

[0004] CN215326590U discloses a device for mounting building curtain wall inspection equipment, which uses a boom mechanism to extend and retract slings to pull an inspection platform for inspection. However, this type of inspection device does not offer an effective solution to the wind pressure sway problem in high-rise and super high-rise building inspection scenarios, resulting in insufficient stability during the inspection process and an inability to adapt to the inspection requirements of complex high-altitude environments. This invention, by configuring double-strand steel cables, adding auxiliary collars to the inspection instrument carrier, and providing a windproof limiting device, ensures that the inspection instrument is always aligned correctly with the inspection object, effectively guaranteeing the stability of the inspection process. Furthermore, the telescopic adjustment function of the boom device can adapt to different inspection distance requirements, meeting the on-site inspection needs of diverse inspection equipment. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent mobile building envelope inspection device and its usage method to solve the technical problems of existing high-rise and super high-rise building envelope inspection devices having poor stability in complex high-altitude environments and being susceptible to swaying due to wind pressure, which leads to insufficient inspection accuracy and low inspection safety; at the same time, it provides its usage method to realize the intelligent, standardized and precise inspection process, and improve inspection efficiency and reliability.

[0006] An intelligent mobile building envelope inspection device includes a mobile device, a vertical roller pulley system, an inspection instrument carrier, and a windproof limiting device; The mobile device is installed on the top of the building, and the vertical roller slide is installed on the mobile device. The mobile device causes the vertical roller slide to protrude outward from the outer wall of the building by a set distance, and drives the vertical roller slide to move laterally back and forth. The testing instrument carrier is a robot carrying testing equipment. The testing instrument carrier is mounted on a vertical pulley system and moves up and down back and forth through the vertical pulley system. The main body of the windproof limiting device is a wall-climbing robot installed on the exterior wall of a building. A limiting arm is fixedly installed on the wall-climbing robot, and a limiter is provided at the end of the limiting arm. The limiter is used to limit the vertical roller pulley assembly.

[0007] A method for using an intelligent mobile building envelope inspection device, the method comprising the following steps: Step 1: Based on the characteristics of the building envelope structure to be inspected, formulate an inspection plan and determine the core contents of the inspection plan, including but not limited to the radar selection of the inspection instrument carrier, the matching of vertical steel cable lengths, the configuration of the number of wind-proof limiting devices, the setting of the distance between the inspection device and the building envelope, and the division of the building envelope inspection units; based on the selected inspection radar type, performance parameters and inspection requirements (plan and set standardized inspection routes). Step 2: Install the mobile building envelope detection device; Step 3: Start the drive motor of the vertical drive wheel to drive the vertical steel cable to rotate, which will move the radar on the detection instrument carrier vertically. After completing the detection of one column of building envelope structural units, control the unlocking device to move horizontally and move the vertical pulley group to the adjacent column of detection units to carry out the detection work of the next column of units; the ground operator uses the rigid rudder to assist in stabilizing the vertical pulley group and control the drive motor of the vertical drive wheel; Step 4: After completing the standardized testing of all planned columns, conduct precise re-inspections on suspicious points, vulnerable parts of the building envelope, and testing units that require detailed investigation by manipulating and adjusting the position of the testing instrument carrier.

[0008] The advantages of this invention are as follows: 1. Significantly improved safety and work efficiency: This invention replaces traditional manual high-altitude operations with suspended platforms, enabling ground control and automated operation, reducing the risks of high-altitude operations for personnel; it also avoids restrictions on drone flights and can achieve full-area coverage detection.

[0009] 2. Intelligent and standardized operation: By pre-setting the detection plan, standardizing the process, and using robotic vehicles, the detection process is intelligently controlled and standardized, reducing human interference and improving the reliability of results. Due to the adoption of standardized detection path planning, the fixed-point re-inspection function can be combined when necessary to take into account both comprehensive screening and key detailed inspection, thereby improving the representativeness and accuracy of the detection data.

[0010] 3. Significantly improved reliability and stability: By configuring double-strand steel cables, adding auxiliary collars to the testing instrument carrier, and setting up windproof limiting devices, the testing instrument can always be aligned with the testing object, effectively ensuring the stability of the testing process.

[0011] 4. High adaptability and flexibility: With the telescopic adjustment function of the extension arm device, it can adapt to the operation requirements of different detection distances and meet the on-site detection needs of diverse detection equipment. Attached Figure Description

[0014] like Figure 1-6 As shown: An intelligent mobile building envelope inspection device includes a mobile device 1, a vertical roller slide block 2, an inspection instrument carrier 3, and a windproof limiting device 4; The mobile device 1 is installed on the top of the building, and the vertical roller slide 2 is installed on the mobile device 1. The mobile device 1 causes the vertical roller slide 2 to protrude outward from the outer wall of the building by a set distance, and drives the vertical roller slide 2 to move laterally back and forth. The detection instrument carrier 3 is a robot carrying detection equipment. The detection instrument carrier 3 is installed on the vertical roller pulley group 2 and moves up and down through the vertical roller pulley group 2. The main body of the windproof limiting device 4 is a wall-climbing robot 41 installed on the exterior wall of the building. A limiting arm 42 is fixedly installed on the wall-climbing robot. A limiter 43 is provided at the end of the limiting arm 42. The limiter 43 is used to limit the vertical roller slip group 2.

[0015] This invention primarily involves installing the mobile device 1 at a suitable location on the top of a building to ensure its stable operation. This structure controls the horizontal movement of the vertical pulley assembly 2. The vertical pulley assembly 2 is then accurately installed onto the mobile device 1, and the distance between the cantilever and the building's exterior wall is adjusted to ensure effective inspection without spatial interference with the building structure during operation. Next, a robot carrying the inspection equipment (actuator 3) is installed onto the vertical pulley assembly 2 and tested to ensure normal vertical reciprocating movement. Simultaneously, the wall-climbing robot 41 of the windproof limiting device 4 is installed at a designated location on the building's exterior wall, the limiting arm 42 is fixed, and the position of the limiter 43 is adjusted to cooperate with the vertical pulley assembly 2, achieving precise limiting of the vertical pulley assembly 2. After completing the above installation and debugging work, the vertical drive wheel 21 of the vertical pulley block 2 is activated. The testing instrument carrier 3 moves vertically under the drive of the vertical drive wheel 21 to perform a single-column vertical test on the building's exterior envelope. After the single-column test is completed, the moving device 1 is activated, which drives the vertical pulley block 2 to move laterally to the next vertical column for testing. Because the windproof limiting device 4 limits the vertical pulley block 2 in real time, the entire testing process is ensured to be safe, stable, and efficient.

[0016] Depending on the type of mobile device, this application extends to the following two embodiments: Example 1 The mobile device 1 includes a mobile support 11, a horizontal extension arm 12, and rollers 13. The mobile support 11 is equipped with a ballast device. The front end of the mobile support 11 is provided with a horizontal extension arm 12, which is connected to the vertical pulley assembly 2 via a hook at the front end. The rollers 13 are located at the bottom of the mobile support 11 to enable the sliding of the mobile support 11.

[0017] The mobile support 11 is made of high-strength alloy material and has sufficient load-bearing capacity to ensure stable support of the vertical pulley block 2 and the testing instrument carrier 3 during the testing process. The configured ballast device can be adjusted in weight according to actual needs to adapt to the testing requirements of different building envelopes and enhance the stability of the device. The hook at the front end of the horizontal extension arm 12 facilitates quick assembly and disassembly with the vertical pulley block 2, improving the efficiency of installation and disassembly.

[0018] Example 2 The mobile device 1 is a transverse pulley assembly 14, which includes a transverse drive wheel 141, a transverse driven wheel 142, a transverse steel cable 143, and an extension arm 144. Multiple extension arms 144 are installed at intervals on the top of the building and extend outward. At least one extension arm 144 has a transverse drive wheel 141 installed at its outer end and is equipped with a drive motor. The remaining extension arms 144 have transverse driven wheels 142 installed at their outer ends. The transverse drive wheel 141 and the transverse driven wheel 142 are connected by a transverse steel cable 143.

[0019] The transverse drive wheel 141 rotates under the drive of the drive motor, thereby pulling the transverse steel cable 143 to move. Since the transverse steel cable 143 is connected to the vertical pulley block 2, it can drive the vertical pulley block 2 to move in the transverse direction. The transverse driven wheel 142 plays a supporting and guiding role, ensuring that the transverse steel cable 143 remains stable during movement. The design of the outrigger 144 allows the entire transverse pulley block 14 to be stably installed on the roof of the building, providing a reliable transverse movement platform for the vertical pulley block 2.

[0020] The vertical pulley assembly 2 includes a vertical drive wheel 21, a vertical driven wheel 22, a vertical steel cable 23, and a rigid rudder 24. The vertical drive wheel 21 is mounted on the moving device 1 and is equipped with a drive motor. The vertical driven wheel 22 is located below the vertical drive wheel 21 and is close to the ground. The vertical driven wheel 22 and the vertical drive wheel 21 are connected by the vertical steel cable 23. The rigid rudder 24 is connected to the vertical driven wheel 22.

[0021] The vertical drive wheel 21 rotates under the drive of the drive motor, thereby moving the vertical steel cable 23 up and down. Since the vertical steel cable 23 is connected to the detection device, it can move the detection instrument carrier 3, which carries the detection device, vertically to achieve the detection (data acquisition) of the building's exterior envelope. The vertical driven wheel 22 supports and guides the vertical steel cable 23, ensuring its stability during movement and preventing deviation or swaying. The rigid steering wheel 24 is connected to the vertical driven wheel 22 and can be used to adjust its direction, thereby controlling the movement trajectory of the vertical steel cable 23, enabling the detection device to more accurately reach the designated location for detection work.

[0022] The testing instrument carrier 3 includes a locking claw 31 and an auxiliary collar 32. The locking claw 31 is fixed to one of the steel cables 23 in the vertical pulley group 2, and the auxiliary collar 32 is sleeved on the other steel cable 23 in the vertical pulley group 2 and slides up and down on the other steel cable 23.

[0023] The latch 31 securely fixes the testing instrument carrier 3 to the steel cable 23, ensuring that the testing instrument will not fall off or shake during movement. The auxiliary collar 32, through its flexible sliding, allows the testing instrument to be adjusted in position as needed to adapt to the testing requirements of building envelope at different heights and locations.

[0024] The detection instrument carrier 3 is an integrated detection device equipped with any one or more combinations of terahertz radar and lidar.

[0025] The limiter 43 is equipped with a remote control system and has an opening and closing function. The remote control system receives the real-time position signal of the detection instrument carrier 3. When the detection instrument carrier 3 approaches, it triggers a retraction avoidance action and when the detection instrument carrier 3 moves away, it re-limits the vertical roller slide group 2.

[0026] It should be noted that the windproof limiting device 4 has spatial interference with the running trajectory of the detection instrument carrier 3. Therefore, a remote control system needs to be installed on the limiter 43 to receive the real-time position signal of the detection instrument carrier 3. When the detection instrument carrier 3 approaches, the limiter 43 releases the vertical pulley group 2 to allow the detection instrument carrier 3 to pass, and then re-limits the vertical pulley group 2.

[0027] A method for using an intelligent mobile building envelope inspection device, the method comprising the following steps: Step 1: Based on the characteristics of the building envelope structure to be inspected, formulate an inspection plan and determine the core contents of the inspection plan, including but not limited to the radar selection of the inspection instrument carrier 3, the length matching of the vertical steel cable 23, the configuration of the number of windproof limiting devices 4, the setting of the distance between the inspection device and the building envelope, and the division of the building envelope inspection units; based on the selected inspection radar type (such as wave frequency, radar power, etc.) and inspection requirements (such as inspection coverage, inspection speed requirements, etc.), plan and set a standardized inspection route; Step 2: Install the intelligent mobile building envelope detection device; Step 3: Start the drive motor of the vertical drive wheel 21 to drive the vertical steel cable 23 to rotate, which in turn moves the radar on the detection instrument carrier 3 vertically (for example, when carrying a terahertz radar, the operating speed is controlled to raise the height of one detection unit every 10 seconds; when carrying a lidar, the operating speed is controlled to be continuous). After completing the detection of one column of building envelope structural units, control the unlocking device to move horizontally, move the vertical pulley group 2 to the adjacent column of detection units, and start the detection work of the next column of units; the ground operator uses the rigid rudder 24 to assist in stabilizing the vertical pulley group 2 and control the drive motor of the vertical drive wheel 21. Step 4: After completing the standardized testing of all planned columns, conduct precise re-inspections on suspicious points, vulnerable parts of the building envelope, and testing units that require detailed investigation by manipulating and adjusting the position of the testing instrument carrier 3.

[0028] A method for using an intelligent mobile building envelope inspection device, characterized in that step 2 includes the following process: Procedure 1: Install mobile device 1 on the roof of the building to be inspected; Procedure 2: Install two components of the vertical pulley system on the roof of the building to be tested, including a vertical drive wheel 21 and a vertical steel cable 23, extend the horizontal extension arm 12, and lower the vertical steel cable 23; Step 3: Install the remaining components of the vertical pulley assembly 2 on the ground, including the vertical driven wheel 22 and the rigid rudder 24; Procedure 4: Fix the testing instrument carrier 3 on the strand of the vertical steel cable close to the building, and put the auxiliary collar 32 on the strand of the vertical steel cable away from the building; Step 5: Install windproof limiting device 4 on the ground, the number of which is determined according to step 1; control the wall-climbing robot 41 to climb along the wall of the building to be inspected to the set height, and the entire inspection device is completed.

[0029] Since there are two versions of the mobile device of the present invention, the operation steps in process 1 also differ depending on the version: When the mobile device 1 includes a mobile support 11, a horizontal extension arm 12 and rollers 13, the installation method of the mobile device 1 is as follows: the mobile support 11 is erected and ballast weight is configured, and the rollers 13 of the mobile support 11 are locked with wheel brakes.

[0030] When the moving device 1 is a transverse pulley block 14, and the transverse pulley block 14 includes a transverse driving wheel 141, a transverse driven wheel 142, a transverse steel cable 143, and an extension arm 144; the moving device 1 is installed as follows: the transverse pulley block 14 is installed between adjacent extension arms 144, and the vertical pulley block 2 is connected to the transverse pulley block 14 through the vertical driving wheel 21 to form a transmission relationship.
