Description

Technical Field

[0001] This invention relates to the field of prefabricated buildings, specifically to a safety protection device for the suspension of prefabricated buildings. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods.

[0003] With the popularization of prefabricated buildings, the construction scenarios of prefabricated buildings are increasing. However, it is inevitable to lift prefabricated building components one by one. During each lifting process, although it is strictly forbidden for people to stand or pass under the lifting path, with the increase in construction site application scenarios, safety accidents will occur from time to time. It is unavoidable that safety problems will be caused by the lack of safety awareness of violators, fear of delaying the construction period, and risky operations when encountering problems. The existing safety management methods alone are no longer sufficient to meet the needs of safe production. There is an urgent need for a modern identification and warning auxiliary device. In view of the above problems, a safety protection device for prefabricated building suspension is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a safety protection device for prefabricated building suspension to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety protection device for suspension of prefabricated buildings, including site equipment, the site equipment including a wall support, a wall being sleeved inside the wall support, a hook being hung on the top of the wall, and a hoisting device being assembled on the top of the hook;

[0006] The wall support is evenly divided into sections and fixed to the ground storage area. A receiving probe is installed at the four corners of the wall support, and a protective strip is installed at the bottom of the receiving probe to prevent entry.

[0007] The top of the wall is provided with either an embedded hook or a ring-shaped hook;

[0008] The hoisting equipment includes a hoisting main beam, the top of which is equipped with a hoisting chain, which is attached to the displacement end of the hoisting equipment at the top. The bottom of the four corners of the hoisting main beam is equipped with a transmitting probe, and downward-mounted cameras are arranged at both ends of the hoisting main beam.

[0009] The number of transmitting probes and receiving probes used is four sets each, and the transmitting probes and receiving probes are wirelessly connected. The transmitting probes transmit signals and the receiving probes receive signals. The distance between a set of transmitting probes and receiving probes placed at the four corners is measured using the time difference principle. The camera shoots an image directly below the hoisting equipment. Both the camera and the transmitting probes are powered by a battery storage module and are wirelessly connected to the background control system.

[0010] After the images captured by the camera are imaged in the background system, they are processed by AI recognition algorithms to identify people or objects moving relative to the ground. Once a moving person or object is detected, the alarm system will be activated to issue an alarm.

[0011] Preferably, the bottom of the receiving probe is equipped with a fixing frame, the fixing frame passes through the outermost corner of the stacking site, and the protective belt is sleeved on the outside of the fixing frame.

[0012] Preferably, the wall includes a wall assembly, the interior of which is integrally formed with connecting steel bars, and the top of the wall assembly has an arc-shaped groove, the center of which is integrally formed with a hook.

[0013] Preferably, the top of the hoisting chain is equipped with a connector, and a safety steel cable is installed between the connector and the connection between the hoisting chain and the hoisting main beam.

[0014] Preferably, two steel pipe structures are welded through both ends of the hoisting main beam, and an internal thread is provided at the top of the steel pipe structure. A screw connector is screwed into the internal thread, and the camera is mounted on the bottom of the screw connector.

[0015] Preferably, the top of the screw connector is hinged with a handle.

[0016] Preferably, the bottom end of the hoisting main beam is welded with a support leg, and the downward extension length of the support leg is greater than the equipment length of the transmitting probe.

[0017] Preferably, the bottom end of the hoisting main beam is attached to the top of the hook via an iron chain.

[0018] Preferably, the hook includes a lifting plate, a handle plate is welded to the outer side of the lifting plate, a connecting hook is welded to the bottom end of the lifting plate, the connecting hook is annular, and a T-shaped groove is formed on the outermost outer wall of the connecting hook, and a connecting ring is welded to the top end of the lifting plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a device and method for measuring hoisting equipment and walls using an infinite distance sensor. During the hoisting process, it ensures that no one walks below the hoisting space, no items are tipped over, or no objects are pushed. This effectively ensures that workers who do not comply with safety regulations will not be exposed below the hoisting path during the hoisting of prefabricated building walls. This solves the hoisting safety accident problem at its root and minimizes the accident rate. Furthermore, it has the function of assisting hoisting workers in planning the hoisting path using virtual software, thereby improving hoisting efficiency. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-7 The present invention provides a technical solution: a safety protection device for suspension of prefabricated buildings, including site equipment 1, site equipment 1 including wall support 13, wall 2 is sleeved inside the wall support 13, hook 4 is hung on the top of the wall 2, and hoisting equipment 3 is assembled on the top of the hook 4.

[0030] The wall support 13 is evenly divided into sections and fixed to the ground stacking area. The four corners of the wall support 13 are equipped with receiving probes 12, and the bottom of the receiving probes 12 is equipped with a protective strip 14 to prevent entry.

[0031] The top of wall 2 is provided with either an embedded hook 24 or a ring hook;

[0032] The hoisting equipment 3 includes a hoisting main beam 34, the top of which is equipped with a hoisting chain 32, which is hooked to the displacement end of the hoisting equipment at the top. The bottom of the four corners of the hoisting main beam 34 is equipped with a transmitting probe 39, and the two ends of the hoisting main beam 34 are equipped with downward-mounted cameras 38.

[0033] The number of transmitting probes 39 and receiving probes 12 is four sets each. The transmitting probes 39 and receiving probes 12 are wirelessly connected. The transmitting probes 39 transmit signals and the receiving probes 12 receive signals. The distance between a set of transmitting probes 39 and receiving probes 12 placed at the four corners is measured using the time difference principle. The camera 38 takes a picture of the image directly below the hoisting equipment 3. Both the camera 38 and the transmitting probes 39 are powered by a battery storage module and are wirelessly connected to the background control system.

[0034] After the images captured by camera 38 are imaged in the background system, they are processed by AI recognition algorithms to identify people or objects moving relative to the ground. Once a moving person or object is detected, the alarm system will be activated and an alarm will be sounded.

[0035] The hoisting equipment is equipped with sensors for measuring wind speed, wind direction, temperature, and humidity, as well as angular velocity sensors, gyroscopes, and orientation sensors.

[0036] The back-end system consists of a wireless signal transceiver module, a computer host, a monitor, an alarm module, and a power supply module;

[0037] The radio signal transceiver module is used to remotely connect to the camera 38 via wireless coding, transmit images in real time, and also transmit the operating status of the camera 38 in real time to ensure the power supply of the camera 38's power supply equipment.

[0038] The computer host is used to load software algorithms to receive real-time images from camera 38 and to detect and process changes in internal pixels in real time.

[0039] The monitor is used to display:

[0040] 1. The image from camera 38 after calculation by the computer host, and the virtual model of hoisting equipment 3 and the overall hoisting range;

[0041] 2. This mainly demonstrates the relative positions of the hoisting equipment 3 and the wall 2 on the top-down plan map during their movement, as well as the relative positions of the installation location and the hoisting equipment 3 and the wall 2.

[0042] 3. Display the relative height of the hoisting equipment 3 to the ground;

[0043] 4. Other external environmental information of the hoisting equipment, such as wind speed and wind direction, to assist the hoisting operator in making judgments;

[0044] The power supply module is used to supply power to all of the above devices.

[0045] The method for measuring the position of the hoisting equipment 3 is the distance measurement method. The electrical signal received by the computer is converted into a digital signal and input into the computer. The receiving probe is set as the initial zero point, and the distance and orientation between every two adjacent receiving probes 12 are determined.

[0046] Based on the above information, and using it as the origin of the computer's internal model, a line is constructed in the virtual three-dimensional space connecting the distance between the transmitting probe 39 and the receiving probe 12. Using the relatively fixed positions of the transmitting probe 39 and the length of the connecting line, combined with three virtual spatial planes with the receiving probe 12 as the origin, projection is performed (the projection relationship is: assuming the distance from each transmitting probe 39 to the receiving probe 12 is l, then l is used as the diagonal of a six-sided cube, and the three virtual spatial planes are used as the three adjacent faces of the six-sided cube, thus obtaining the virtual...). The height of the hoisting equipment 3 above the ground is the height of the hexagonal cube after projection (height of the hexagonal cube). The relative position of a single transmitting probe 39 to the receiving probe 12 in the same group (length and width of the hexagonal cube) can also be obtained. Therefore, the relative position between the virtual quadrilateral formed by the four transmitting probes 39 and the virtual quadrilateral formed by the four receiving probes 12 can be directly obtained and rendered by software and projected onto the display. Thus, the distance between the hoisting equipment 3 and the ground and the relative position of the hoisting equipment 3 relative to the hoisting range can be calculated.

[0047] Displaying the above information in the worker's crane cab can assist in planning the crane path. Simultaneously, the above calculation methods can update the prefabricated building's wall model in real-time to the computer's internal model. In terms of the rendering effect on the monitor, it's equivalent to comparing each numbered prefabricated building module with the overall building's BIM model after it reaches the designated location, displaying a building block effect. This shows the already assembled prefabricated wall structure, the information on the next structure to be lifted, and its installation location. The crane operator can more intuitively see the location, shape, and installation position of the next wall to be lifted. Further research and development can use the above algorithms as a basis to automatically plan the crane path using algorithmic data. After automatic path planning is implemented, it can output analog signals in conjunction with an alarm system to achieve autonomous driving during the lifting path from the start to the end of the lifting process.

[0048] During the movement of camera 38, the pixels captured are calculated in the background to determine the relative distance and vector direction of the movement of each pixel. This is combined with predictions of the upcoming orientation and speed from various sensors. By comparing these values ​​with the relative positions of pixels within the predicted fixed area of ​​the image and the pixels at the same location captured in the image, if the error exceeds a certain range, it is determined that there is a moving object or person in the captured image. The computer algorithm then creates a virtual frame around all pixels that match the displacement, distinguishing them with different colors on the display screen. This allows for real-time monitoring of moving objects and people along the hoisting process and path. If an alarm is triggered, and the worker confirms the alarm, the hoisting equipment 3 can be moved to a safe distance from the moving object or person below, and the person or moving object can be warned or dealt with, ensuring that there are no people or moving objects below during the hoisting process and guaranteeing safety.

[0049] This invention provides a device and method for measuring hoisting equipment and walls using an infinite distance sensor. During hoisting, it ensures that no one walks below the hoisting space, no items are tipped over, and no objects are pushed. This effectively prevents workers who do not comply with safety regulations from being exposed below the hoisting path during the hoisting of prefabricated building walls, thus addressing hoisting safety accidents at their source and minimizing the accident rate. Furthermore, it assists hoisting workers in planning hoisting paths using virtual software, improving hoisting efficiency.

[0050] Specifically, a mounting bracket 11 is fitted to the bottom of the receiving probe 12. The mounting bracket 11 is located at the outermost corner of the stacking area, and a protective strip 14 is attached to the outside of the mounting bracket 11. Depending on the shape of the area, the installation positions of the receiving probe 12 and the mounting bracket 11 need to maintain a right angle as much as possible. Furthermore, the receiving probe 12 and the transmitting probe 39 can use radio wave communication ranging with simple coded information. The radio signal is encoded using a non-standard radio spectrum. One of the existing encoding methods can be used, mainly for calibrating the transmitting probe 39 to transmit this segment of radio waves. The signal is time-coded. After the signal is received inside the receiving probe 12, the information is decoded to obtain the transmission time. This time is compared with the reception time at one end of the receiving probe 12. By multiplying the time difference by the propagation speed of the radio signal at that frequency, the distance information between a set of transmitting probes 39 and receiving probes 12 can be directly obtained. The information contained within the code should also include the numbers of different transmitting probes 39 and receiving probes 12. The transmitting and receiving signal information is the same between each set of transmitting probes 39 and receiving probes 12, while the transmitting and receiving signal information is different between adjacent sets of transmitting probes 39 and receiving probes 12. In addition to the above methods for distinguishing signals from different sets of transmitting probes 39 and receiving probes 12, different frequency bands can also be used to distinguish signals from different groups of transmitting probes 39 and receiving probes 12.

[0051] The transmitting probe 39 and the receiving probe 12 must be set up in groups, and each group must be connected and calibrated separately. The minimum number of transmitting probes 39 and receiving probes 12 used is 3 groups, preferably 4 groups. In the case of use where the stacking site is not a quadrilateral, the measurement accuracy can also be improved by increasing the number of groups of transmitting probes 39 and receiving probes 12.

[0052] Specifically, the wall 2 includes a wall component 21, the interior of which is integrally formed with connecting steel bars 22, and the top of the wall component 21 is provided with an arc-shaped groove 23, and the center of the groove 23 is integrally formed with a hook 24.

[0053] Hook 24 is a T-shaped structure that fits into the interior of T-slot 45 and can be hung using the outer wall of hook 4. It is suitable for prefabricated building construction where it is not possible to make protruding parts at the top. Another type of hook 24 is a common ring structure, where hook 4 can be directly connected using the opening of connecting buckle 44.

[0054] Specifically, a connector 31 is fitted at the top of the hoisting chain 32. A safety cable 33 is fitted between the connector 31 and the connection between the hoisting chain 32 and the hoisting main beam 34. The installation cable 33 passes through the center of the loop of the hoisting chain 32. If the main load-bearing hoisting chain 32 breaks, the safety cable 33 will act as a buffer and connect the position as a safety measure, ensuring that the entire equipment returns to the ground safely and slowly, thus improving safety.

[0055] Specifically, two steel pipe structures are welded through both ends of the hoisting main beam 34. An internal thread 35 is provided at the top of the steel pipe structure. A screw connector 36 is screwed into the internal thread 35. The camera 38 is assembled at the bottom of the screw connector 36. The threaded structure facilitates the installation and removal of the camera 38 on the ground, making maintenance easier and facilitating the replacement of the battery pack installed inside the screw connector 36, thus ensuring battery life.

[0056] Specifically, the top of the screw connector 36 is hinged with a handle 37 to facilitate the installation and removal of the screw connector 36.

[0057] Specifically, a support foot 310 is welded to the bottom end of the hoisting main beam 34. The downward extension length of the support foot 310 is greater than the equipment length of the transmitting probe 39. The support foot 310 is used to protect the transmitting probe 39 from damage when the hoisting equipment 3 is placed on the ground.

[0058] Specifically, the bottom end of the hoisting main beam 34 is attached to the top of the hook 4 via an iron chain.

[0059] Specifically, the hook 4 includes a lifting plate 41, a handle plate 42 welded to the outer side of the lifting plate 41, a connecting hook 44 welded to the bottom end of the lifting plate 41, the connecting hook 44 is annular, and a T-slot 45 is provided on the outermost outer wall of the connecting hook 44. A connecting ring 43 is welded to the top end of the lifting plate 41.
