Description

Technical Field

[0001] This invention relates to the field of monitoring technology for BIM building construction supervision, specifically to a monitoring device for monitoring the progress of BIM building construction. Background Technology

[0002] Building Information Modeling (BIM) is a new tool in architecture, engineering, and civil engineering. The term "Building Information Modeling" was coined by Autodesk to describe computer-aided design that primarily uses 3D graphics, is object-oriented, and relates to architecture. The concept was initially popularized by Jerry Laiserin, who promoted the technologies provided by Autodesk, Bentley Systems, and Graphisoft. BIM technology is a data-driven tool applied to engineering design, construction, and management. Through the integration of digitized and informational models of buildings, it facilitates sharing and transmission throughout the entire lifecycle of project planning, operation, and maintenance. This enables engineering technicians to correctly understand and efficiently respond to various building information, providing a foundation for collaborative work among design teams and all parties involved in the construction, including building and operation units. It plays a crucial role in improving productivity, saving costs, and shortening construction periods. How to easily achieve effective real-time monitoring of the building construction process and establish a progress model using BIM technology is a problem that needs to be solved.

[0003] Currently, most existing methods for BIM-based supervision and monitoring rely on manual data collection, such as taking photos or using surveying tools. The measured data is then processed and compared with the data in the drawings, or with the initial complete model after modeling, to determine the progress and quality of construction. However, manual data collection and judgment are inefficient. Even with the use of surveying tools, workers still need to perform measurements manually, requiring lengthy equipment adjustments, which does not effectively improve efficiency. Furthermore, the complex environment of construction sites increases the safety risks for inspectors due to prolonged measurement and data collection, making accidents more likely.

[0004] Based on this, the present invention designs a monitoring device for BIM building construction progress supervision to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a monitoring device for BIM building construction progress supervision, so as to solve the problems of low data acquisition efficiency and safety hazards in the prior art as mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a monitoring device for BIM building construction progress supervision, comprising a housing, a suspension device on the housing, the suspension device comprising a wing fixedly connected to the housing, a propeller rotatably connected to the wing, a motor fixedly connected to the wing, the output shaft of the motor fixedly connected to the propeller, a walking device on the housing, the walking device comprising two sets of track groups mirror-arranged below the housing, each track group comprising a synchronous belt disposed below the housing and a support rod fixedly connected to the lower surface of the housing, a rotating rod rotatably connected to the support rod, a limit groove formed in the inner wall of the synchronous belt, a synchronous wheel fixedly connected to the rotating rod and rotatably connected to the limit groove, the walking device further comprising a drive mechanism disposed on the housing for driving the rotating rods of the two sets of track groups to rotate, and a monitoring device and a laser measuring device on the housing for monitoring purposes; The housing is also equipped with a crawling device, which includes crawling claw assemblies arranged in an equally spaced array on the timing belt. The crawling claw assembly includes a sliding rod that is slidably connected to the timing belt, and a suction cup is fixedly connected to one end of the sliding rod located outside the timing belt. The crawler claw assembly also includes a pressing device, which includes a fixed rod fixedly connected to the lower surface of the housing. The end of the fixed rod away from the housing passes through the rotating rod and extends into the inner side of the timing belt and is fixedly connected to a wedge. The outer wall of the slide rod is fitted with a spring that can reset the slide rod to the inside of the timing belt. The crawler claw assembly also includes an unlocking device, which includes a fixed rod fixedly connected to the lower surface of the housing. The end of the fixed rod away from the housing passes through the rotating rod and extends into the inner side of the synchronous belt, where a wedge block two is fixedly connected. The slide rod has a connecting groove extending downward into the suction cup. The slide rod is slidably connected to a release rod at its upper limit. The outer wall of the release rod away from the wedge block two is fitted with a sealing sleeve, which is fixedly connected to the outer wall of the slide rod. The inner end of the release rod away from the wedge block two has a release cavity, which communicates with the connecting groove. The portion of the release rod covered by the sealing sleeve has a release hole communicating with the release cavity. The outer wall of the release rod is fitted with a spring that allows the release rod to reset towards the wedge block two.

[0007] As a further embodiment of the present invention, the suspension device is provided with four sets of symmetrically distributed on both sides of the two ends of the housing.

[0008] As a further aspect of the present invention, a hanging rod is fixedly connected to the upper surface of the housing, and a brush for cleaning the suction cup is fixedly connected to the end of the hanging rod away from the housing.

[0009] As a further embodiment of the present invention, the monitoring device and the laser measuring device include a mounting base fixedly connected to one end of the housing, and a second motor fixedly connected to the housing at the inner side of the mounting base. A rotating seat is fixedly connected to the output shaft of the second motor, and the rotating seat is rotatably connected to the mounting base. A data acquisition module is rotatably connected to the rotating seat. The output shaft of the third motor is fixedly connected to the data acquisition module. A monitoring camera and a laser rangefinder are provided on the data acquisition module.

[0010] As a further embodiment of the present invention, the driving mechanism includes a motor four fixedly connected to a support rod, and gears are fixedly connected to the output shaft of the motor four and the end of the rotating rod away from the synchronous wheel, and the two gears mesh with each other.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This technology uses a motor to drive a propeller, which, when blowing air, generates a counter-force that allows the unit to lie on a wall. Combined with a synchronous belt, this enables the unit to monitor, photograph, and measure the wall structure, checking construction quality and whether workers are operating according to regulations. No manual measurement is required; data collection can be achieved via remote control of the unit. Furthermore, the motor can reverse the propeller's rotation, allowing the unit to fly and perform aerial measurement and monitoring, further improving data acquisition efficiency and the variety of data collected. This facilitates the creation of BIM data and the assessment of construction progress.

[0012] 2. The suction cups enhance the box's grip on the wall, ensuring a better fit and preventing it from falling off, thus improving safety. This also guarantees the effectiveness of monitoring and measurement, while improving the box's climbing ability. Furthermore, when the box is in flight mode, the suction cups act as shock absorbers upon landing, providing overall protection. The pressing device compresses each suction cup just as it makes full contact with the wall, ensuring the suction force of each cup and maintaining the synchronous belt's wall-mounting capability. This significantly improves the stability of the box's climbing motion. The unlocking device allows the suction cups to unlock in advance, eliminating the need for the synchronous belt to rotate, reducing wear on the drive unit, improving stability, and minimizing vibrations when the suction cups are pulled out by the synchronous belt, thereby ensuring accuracy during monitoring, shooting, and measurement.

[0013] 3. It can automatically clean the suction cup with a brush, thus preventing dust from sticking to the suction cup. This prevents gaps from forming where a lot of dust, dirt, or gravel sticks to the suction cup when it is used for wall cleaning next time. This allows air to flow into the suction cup, which will prevent the suction cup from sticking tightly to the wall. This reduces the wall climbing ability of the synchronous belt and prevents it from sticking to the wall, creating a safety hazard. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 8This invention provides a technical solution: a monitoring device for BIM building construction progress supervision, including a housing 01. A levitation device is installed on the housing 01. The levitation device includes a wing 02 fixedly connected to the housing 01, a propeller 04 rotatably connected to the wing 02, and a motor 03 fixedly connected to the wing 02. The output shaft of the motor 03 is fixedly connected to the propeller 04. A walking device is also installed on the housing 01, comprising two sets of tracks mirror-mounted below the housing 01. The assembly includes a timing belt 05 disposed below the housing 01 and a support rod 21 fixedly connected to the lower surface of the housing 01. A rotating rod 22 is rotatably connected to the support rod 21. A limiting groove 30 is formed in the inner wall of the timing belt 05. A timing wheel 17 with limiting and rotatably connected in the limiting groove 30 is fixedly connected to the rotating rod 22. The walking device also includes a drive mechanism disposed on the housing 01 for driving the rotating rod 22 of the two sets of track assemblies to rotate. The housing 01 is also provided with a monitoring device and a laser measuring device for monitoring.

[0019] When motor 03 starts working, it drives propeller 04 to rotate, thereby generating wind. In use, the unit 01 is held against the wall, and then motor 03 is started. Motor 03 drives propeller 04 to rotate and generate wind. The wind direction is from the side closer to the wall to the side farther away from the wall. Therefore, when the wind generated by propeller 04 is sufficient, propeller 04 can keep the unit 01 against the wall via synchronous belt 05. It will not fall off even if it is not held. Then, the drive device drives the rotating rod 22 to rotate, which drives synchronous wheel 17 to rotate, which in turn drives synchronous belt 05 to rotate, thereby realizing the walking function. The monitoring device and laser measuring device can be installed at the lower end of the walking direction of the unit 01. As the unit 01 moves from bottom to top or from top to bottom, the height of the floor can be measured by the laser rangefinder. At the same time, the construction situation on the outside of the floor can be captured by the monitoring device.

[0020] When implementing propeller 04, one can be placed in the middle of the housing 01, or two can be placed at the front and rear ends of the housing 01. Both methods ensure that the reverse thrust of the wind force on the housing 01 is uniform, allowing the housing 01 to hover stably against the wall. Once the housing 01 is stable, movement is achieved by driving the synchronous belt 05. The synchronous belt 05 adapts well to different wall surfaces, providing a large contact area and improved grip, thus preventing slippage. Furthermore, since the two rotating rods 22 are driven by two separate drive devices, they can move forward or backward when working synchronously, and turn when driven individually. When moving vertically up and down on the wall, a laser rangefinder can measure the height, and a monitoring device can be used to inspect the wall's construction status, observe whether construction workers are operating according to regulations, and use a laser measuring device to detect the wall's verticality to determine if the wall meets quality standards. Horizontal movement around the building can check the construction quality of the walls around the floors. It can also check the levelness of each surface of a building and whether the width of each surface meets the standards. Furthermore, during use, it can be used without being placed against a wall. The unit 01 can be placed horizontally on the ground, and the motor 03 drives the propeller 04 to rotate in the opposite direction, generating downward wind force to provide buoyancy, enabling the unit 01 to take off and fly, thus enabling drone operation. The unit 01 can then be controlled to fly and photograph or measure buildings, increasing the device's applicability and practicality. In addition, it can be used not only for exterior walls but also for interior walls for inspection and photography. Photograph; Because the timing belt 05 has a limiting groove 30, it can limit the timing pulley 17, so that the timing pulley 17 will not slip on the timing belt 05, ensuring the transmission effect, thus ensuring stability, and thus ensuring the accuracy of measurement; The propeller 04 is installed on the wing 02, and the blade tip of the propeller 04 extends into the inner side of the wing 02, so that the wing 02 can play a function of limiting the airflow, ensuring that the airflow can pass through the middle of the propeller 04, thus ensuring the generated wind force and the wind force reverse thrust, thus ensuring that the machine box 01 can fly smoothly and climb walls. This technology uses motor 03 to drive propeller 04 to rotate. When blowing air, the reverse thrust of the air allows the housing 01 to be mounted on a wall. Combined with the movement of the synchronous belt 05, it enables the monitoring, imaging, and measurement of the wall, checking the quality of construction and whether the construction personnel are operating in accordance with regulations. In addition, motor 03 can drive propeller 04 to rotate in the opposite direction, thereby enabling the housing 01 to fly and achieve aerial measurement and monitoring functions.

[0021] As a further embodiment of the present invention, the housing 01 is also provided with a crawling device, the crawling device including crawling claw assemblies arranged in an equally spaced array on the synchronous belt 05, the crawling claw assembly including a sliding rod 08 that is limited and slidably connected to the synchronous belt 05, and a suction cup 09 is fixedly connected to one end of the sliding rod 08 located outside the synchronous belt 05.

[0022] When the drive unit rotates the synchronous belt 05 to achieve the crawling function, the synchronous belt 05 drives the crawling claw assembly to rotate simultaneously. Each time the synchronous belt 05 rotates the suction cup 09 from top to bottom to the wall-mounted position, it squeezes the suction cup 09. The wind force generated by the propeller 04 ensures the squeezing force of the synchronous belt 05 on the suction cup 09, thus squeezing out the air inside the suction cup 09, creating a near-vacuum inside, allowing the suction cup 09 to adhere to the wall. As the synchronous belt 05 moves forward, its end pulls the suction cup 09 back up, releasing it from the wall. The suction cup 09 improves the grip of the housing 01 on the wall, ensuring better adhesion and preventing it from falling, thus enhancing safety. It also ensures the monitoring and measurement effects, and improves the climbing ability of the housing 01. Furthermore, when the housing 01 is in flight mode, the suction cup 09 also acts as a shock absorber when it lands, providing overall protection.

[0023] As a further embodiment of the present invention, the crawler claw assembly also includes a pressing device, which includes a fixing rod 20 fixedly connected to the lower surface of the housing 01. One end of the fixing rod 20 away from the housing 01 passes through the rotating rod 22 and extends into the inner side of the synchronous belt 05 and is fixedly connected to a wedge block 10. The outer wall of the slide rod 08 is fitted with a spring that can reset the slide rod 08 into the synchronous belt 05.

[0024] See Figure 1 The left end is the head of the housing 01, and the right end is the tail. The housing 01 moves from right to left, while the synchronous belt 05 rotates counterclockwise. Whenever the synchronous belt 05 drives the slide rod 08 to rotate the suction cup 09 to the wall-mounted position, the wedge block 10 pushes the slide rod 08 to slide away from the wedge block 10 on the synchronous belt 05. At this time, the suction cup 09 is completely attached to the wall. The pressure of the wedge block 10 on the slide rod 08 causes the slide rod 08 to squeeze the suction cup 09, thus squeezing out the air inside the suction cup 09. The pressing device can press each suction cup 09 just as it reaches full contact with the wall, ensuring the adhesion of each suction cup 09 to the wall and thus ensuring the wall-mounting ability of the synchronous belt 05. This greatly improves the crawling stability of the housing 01. (For further reference) Figure 5 (The forward direction of the box 01 is from left to right).

[0025] As a further embodiment of the present invention, the crawler claw assembly also includes an unlocking device, which includes a fixing rod 20 fixedly connected to the lower surface of the housing 01. The end of the fixing rod 20 away from the housing 01 passes through the rotating rod 22 and extends into the inner side of the synchronous belt 05 and is fixedly connected to the wedge block 18 inside the limiting groove 30. The slide rod 08 has a connecting groove 26 that extends downward to the inside of the suction cup 09. The slide rod 08 is slidably connected to the upper limit of the release rod 24. The outer wall of the release rod 24 away from the wedge block 18 is fitted with a sealing sleeve 25. The sealing sleeve 25 is fixedly connected to the outer wall of the slide rod 08. The inner end of the release rod 24 away from the wedge block 18 has a release cavity 27. The release cavity 27 communicates with the connecting groove 26. The part of the release rod 24 covered by the sealing sleeve 25 has a release hole 28 that communicates with the release cavity 27. The outer wall of the release rod 24 is fitted with a spring that can reset the release rod 24 towards the wedge block 18.

[0026] See Figure 5 as well as Figure 6 As the housing 01 moves forward, each suction cup 09 moves from the right end to the leftmost end of the synchronous belt 05. Whenever the slide rod 08 moves to the position of the second wedge 18, the second wedge 18 pushes the release rod 24 to slide away from the second wedge 18 on the slide rod 08. This causes the release hole 28 on the release rod 24 to move out from inside the sealing sleeve 25, thus the sealing sleeve 25 no longer blocks the release hole 28. This allows the inner wall of the suction cup 09 to communicate with the outside through the release hole 28 and the connecting groove 26. Air can then flow through the release hole 28 into the connecting groove 26 and then into the suction cup 09, thus removing the vacuum inside the suction cup 09 and preventing it from adhering to the wall, achieving the unlocking effect (see reference). Figure 6 and Figure 7 As the sliding rod 08 moves past the position of the wedge block 18, it can be reset by the spring reset action of the release rod 24. The unlocking device allows the suction cup 09 to be unlocked in advance, eliminating the need for the synchronous belt 05 to rotate to unlock the suction cup 09. This reduces wear on the drive unit, improves stability, and reduces the possibility of vibration when the suction cup 09 is pulled out by the synchronous belt 05, thereby ensuring accuracy during monitoring, shooting, and measurement.

[0027] As a further embodiment of the present invention, the suspension device is provided with four sets of symmetrically distributed on both sides of the two ends of the housing 01.

[0028] See Figure 1The four sets of settings ensure wind resistance, allowing the housing 01 to remain firmly against the wall and the synchronous belt 05 to climb smoothly. Furthermore, they ensure a more even distribution of wind force on the housing 01, preventing one end or side from tilting up and ensuring both synchronous belts 05 remain firmly against the wall. This guarantees that the monitoring and measurement angles are always consistent, thus improving accuracy.

[0029] As a further embodiment of the present invention, a hanging rod 06 is fixedly connected to the upper surface of the housing 01, and a brush 07 capable of cleaning the suction cup 09 is fixedly connected to the end of the hanging rod 06 away from the housing 01.

[0030] See Figure 1 Because the suction cup 09 needs to be attached to the wall when the synchronous belt 05 is moving, excessive dust, dirt, or sand particles from concrete may stick to the suction cup 09. When the suction cup 09 rotates with the synchronous belt 05 to the position of the boom 06, the brush 07 can automatically clean the suction cup 09. This prevents the suction cup 09 from having a lot of dust, dirt, or sand stuck to it when it is used to clean the wall next time, which would create gaps and allow air to flow into the suction cup 09. This would prevent the suction cup 09 from sticking tightly to the wall, thus reducing the climbing ability of the synchronous belt 05 and preventing it from sticking to the wall, creating a safety hazard.

[0031] As a further embodiment of the present invention, the monitoring device and the laser measuring device include a mounting base 13 fixedly connected to one end of the housing 01, and a second motor 12 fixedly connected to the housing 01 at the inner side of the mounting base 13. A rotating seat 15 is fixedly connected to the output shaft of the second motor 12, and the rotating seat 15 is rotatably connected to the mounting base 13. A data acquisition module 16 is rotatably connected to the rotating seat 15. The output shaft of the third motor 14 is fixedly connected to the data acquisition module 16. A monitoring camera and a laser rangefinder are provided on the data acquisition module 16.

[0032] The surveillance camera can capture photos and videos, allowing for direct observation or conversion into 2D or 3D data for comparison with existing data. Simultaneously, the laser rangefinder can determine length, thereby assessing construction height or wall levelness. During wall-climbing inspections, the data acquisition module 16 needs to be in [position missing]. Figure 1 In this state, when the housing 01 moves from right to left, the laser rangefinder on the housing 01 can make the laser bounce back from the ground to the receiver, thereby determining the altitude. During flight testing, the angle can be adjusted by the rotation of the mounting base 13 driven by motor 2 12 and the rotation of the data acquisition module 16 driven by motor 3 14, so as to flexibly take pictures and measure and adapt to different usage needs.

[0033] As a further embodiment of the present invention, the drive mechanism includes a motor 29 fixedly connected to the support rod 21. Gears 23 are fixedly connected to the output shaft of the motor 29 and to the end of the rotating rod 22 away from the synchronous wheel 17, and the two gears 23 mesh with each other.

[0034] When motor 4 29 is working, it can drive gear 23 to rotate through the output shaft, and then drive the rotating rod 22 to rotate through the transmission of gear 23, thereby driving synchronous pulley 17 to rotate. The rotation of synchronous pulley 17 will drive synchronous belt 05 to rotate, thereby realizing the function of moving the machine box 01. When two motors 4 29 work at the same time, they can drive the machine box 01 to move forward or backward. When one works, it can realize the function of turning the machine box 01.
