Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a device for precise docking and positioning of prefabricated building components. 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 employ standardized design, factory production, assembly-based construction, information management, and intelligent applications, they represent modern industrialized production methods.

[0003] Currently, in the construction of prefabricated buildings, the hoisting and placement of prefabricated components is the most critical process. First, a tower crane is used to lift the prefabricated components. The tower crane operator needs to maintain real-time communication with the signalman at the hoisting site, and then coordinate with the on-site construction workers to finally complete the hoisting and placement of the prefabricated components. While this achieves the goal of hoisting and placing the prefabricated components, it requires a large number of people to coordinate during the process, thus affecting installation efficiency. Therefore, there is an urgent need to address this issue. Summary of the Invention

[0004] In view of this, the present invention provides a precise docking and positioning device for prefabricated components of prefabricated buildings. The main technical problem to be solved is that the existing prefabricated components are relatively troublesome to hoist and position.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a precise docking and positioning device for prefabricated components of assembled buildings, including a building base plate, a moving mechanism provided at the upper end of the building base plate, a left and right limiting mechanism provided on the moving mechanism, a front and back limiting mechanism provided on the left and right limiting mechanism, and a prefabricated component provided inside the left and right limiting mechanism and the front and back limiting mechanism, wherein the left and right limiting mechanism is used to limit the left and right position of the prefabricated component, and the front and back limiting mechanism is used to limit the front and back position of the prefabricated component; The precast component has a positioning groove on its lower end face, and the upper end of the building base plate is fixedly connected with a steel bar, which cooperates with the positioning groove. The precast component is provided with a hanger at its upper end, and a clamping mechanism is provided inside the hanger for clamping the precast component.

[0006] By adopting the above technical solution, during use, the moving mechanism is installed on the upper part of the building's foundation slab. Then, the moving mechanism is used to move the left and right limiting mechanisms and the front and rear limiting mechanisms to positions corresponding to the reinforcing bars. Subsequently, the precast component is hoisted to the designated area, and the clamping mechanism on the hoist securely holds the precast component, ensuring its stability during hoisting. At this point, the left and right limiting mechanisms are adjusted to accurately align with the left and right sides of the precast component. After adjusting the left and right limiting mechanisms, the front and rear limiting mechanisms are adjusted to precisely position the front and rear of the precast component, ensuring accurate alignment between the precast component and the reinforcing bars on the building's foundation slab. This makes the hoisting and placement of the precast component more convenient and faster, thereby improving installation efficiency.

[0007] As a further description of the above technical solution: The moving mechanism includes a mounting plate, an electric telescopic rod, a moving frame, a slider, and a slide rail. The mounting plate is fixedly connected to the upper end of the building base plate. The electric telescopic rod and the slide rail are fixedly connected to the upper end of the mounting plate. There are two slide rails, which are symmetrically distributed on both sides of the upper end of the mounting plate. The extended end of the electric telescopic rod is fixedly connected to the moving frame. The lower end of the moving frame is fixedly connected to the slider. The slider and the slide rail are slidably connected.

[0008] By adopting the above technical solution, when in use, the electric telescopic rod is activated, and the extended end of the electric telescopic rod will push the moving frame to move. Since the lower end of the moving frame is fixedly connected to the slider, and the slider is slidably connected to the slide rail, the moving frame can move smoothly under the guidance of the slide rail, thereby driving the left and right limiting mechanism and the front and rear limiting mechanism to move to the position corresponding to the steel bar, so as to prepare for the subsequent hoisting and placement of the precast components.

[0009] As a further description of the above technical solution: The left and right limiting mechanism includes a first bidirectional threaded rod, a first moving rod, a first handle, a first limiting frame, and a first rotating roller. The first bidirectional threaded rod is rotatably connected inside the moving frame. The first handle is fixedly connected to the end of the first bidirectional threaded rod. The first moving rod is threadedly connected to the first bidirectional threaded rod. The first limiting frame is fixedly connected to the upper end of the first moving rod. The first rotating roller is rotatably connected inside the first limiting frame.

[0010] By adopting the above technical solution, when in use, rotating the first handle drives the first bidirectional threaded rod to rotate. Since the first bidirectional threaded rod is threadedly connected to the first moving rod, when the first bidirectional threaded rod rotates, it will drive the first moving rod to move, thereby driving the first limiting frame to move. The first limiting frame is rotatably connected to the first rotating roller. The first rotating roller can reduce the friction between the precast component and the precast component, making it easier for the precast component to fall. By adjusting the position of the first limiting frame, it can accurately fit the left and right sides of the precast component, thereby limiting the left and right positions of the precast component.

[0011] As a further description of the above technical solution: There are two first moving rods, which are symmetrically distributed on the first bidirectional threaded rod, and the internal threads of the two first moving rods are in opposite directions.

[0012] By adopting the above technical solution, when in use, since the internal threads of the two first moving rods are in opposite directions, the two first moving rods will move in opposite directions at the same time, thereby driving the two first limiting frames to move simultaneously to the middle or both sides, realizing the synchronous limitation of the left and right sides of the prefabricated component, and improving the accuracy and efficiency of the limitation.

[0013] As a further description of the above technical solution: The front and rear limiting mechanism includes a mounting frame, a second bidirectional threaded rod, a second handle, a second moving rod, a second limiting frame, and a second rotating roller. The mounting frame is fixedly connected to the outside of the first limiting frame, and the second bidirectional threaded rod is rotatably connected inside the mounting frame. The end of the second bidirectional threaded rod is fixedly connected to the second handle, and the second moving rod is threadedly connected to the second bidirectional threaded rod. The end of the second moving rod away from the second bidirectional threaded rod is fixedly connected to the second limiting frame, and the second rotating roller is rotatably connected inside the second limiting frame.

[0014] By adopting the above technical solution, when in use, rotating the second handle drives the second bidirectional threaded rod to rotate. Since the second bidirectional threaded rod is threadedly connected to the second moving rod, when the second bidirectional threaded rod rotates, it will drive the second moving rod to move, thereby driving the second limiting frame to move. The second limiting frame is rotatably connected to the second rotating roller. The second rotating roller can reduce the friction between the precast component and the precast component, making it easier for the precast component to fall. By adjusting the position of the second limiting frame, it can accurately fit the front and rear sides of the precast component, thereby limiting the front and rear position of the precast component.

[0015] As a further description of the above technical solution: There are two second moving rods, which are symmetrically distributed on the second bidirectional threaded rod, and the internal threads of the two second moving rods are in opposite directions.

[0016] By adopting the above technical solution, when in use, since the internal threads of the two second moving rods are in opposite directions, when the second bidirectional threaded rod rotates, the two second moving rods will move in opposite directions at the same time, thereby driving the two second limiting frames to move to the middle or both sides at the same time, which improves the accuracy of the limiting and the construction efficiency.

[0017] As a further description of the above technical solution: A binocular camera is fixedly connected to the upper end of the mobile frame, and the binocular camera is located in the middle of the upper end of the mobile frame.

[0018] By adopting the above technical solution, when in use, the binocular camera can capture the position information of the prefabricated components in real time, and accurately calculate the deviation between the prefabricated components and the predetermined installation position through image processing and analysis technology.

[0019] As a further description of the above technical solution: The clamping mechanism includes a third bidirectional threaded rod, a motor, and clamping components. The third bidirectional threaded rod is rotatably connected inside the hanger, and clamping components are threaded onto the third bidirectional threaded rod. There are two clamping components, which are symmetrically distributed on the third bidirectional threaded rod. The motor is fixedly connected to the side end of the hanger, and the output end of the motor is fixedly connected to the third bidirectional threaded rod.

[0020] By adopting the above technical solution, during use, starting the motor causes its output to rotate the third bidirectional threaded rod. Since the third bidirectional threaded rod has two symmetrically distributed clamping members connected by threads, and the internal threads of the two clamping members are in opposite directions, the rotation of the third bidirectional threaded rod drives the two clamping members to move simultaneously towards the center or both sides. When it is necessary to clamp the precast component, the motor drives the third bidirectional threaded rod to rotate, causing the two clamping members to move simultaneously towards the center, thereby tightly clamping the precast component and ensuring its stability during hoisting. When it is necessary to release the precast component, the motor rotates in the opposite direction, driving the third bidirectional threaded rod to rotate in the opposite direction, causing the two clamping members to move simultaneously to both sides, thereby releasing the precast component.

[0021] As a further description of the above technical solution: The clamping component includes a clamping block, a third moving rod, a guide block, a guide frame, a spring, a transmission rod, an L-shaped rod, and a clamping plate. The clamping block is threaded onto the third bidirectional threaded rod. The clamping block is slidably connected to the hanger. The third moving rod is slidably connected inside the clamping block. The end of the third moving rod away from the precast component is rotatably connected to the transmission rod. The end of the transmission rod away from the moving rod is rotatably connected to the L-shaped rod. The L-shaped rod is slidably connected to the clamping block. The clamping plate is fixedly connected to the end of the L-shaped rod. The clamping plate is located at both ends of the precast component. The guide frame is fixedly connected to the side end of the clamping block. A guide block is slidably connected to the guide frame. The guide block is fixedly connected to the third moving rod. A spring is provided on the guide frame.

[0022] By adopting the above technical solution, during use, as the clamping block moves towards the precast component, it also drives the third moving rod to move. After the third moving rod contacts the precast component, it will be squeezed to move, and then, with the cooperation of the transmission rod, it will drive the L-shaped rod to move. As the L-shaped rod moves, it will also drive the clamping plate to move towards the precast component. In this way, with the cooperation of the clamping block and the clamping plate, the precast component can be clamped and fixed in multiple directions, thereby improving the stability of the precast component clamping. At the same time, the movement of the third moving rod also drives the guide block to slide on the guide frame, thereby compressing the spring. The compressed spring is conducive to the third moving rod to return to its original position.

[0023] By employing the above technical solution, the prefabricated component precise docking and positioning device of the present invention has at least the following beneficial effects: 1. Compared with existing technologies, this prefabricated component precision docking and positioning device for prefabricated buildings achieves precise positioning of prefabricated components in both horizontal and vertical directions through the inclusion of a moving mechanism, left-right limiting mechanisms, and front-back limiting mechanisms. The moving mechanism drives the left-right and front-back limiting mechanisms to their designated positions, providing a foundation for the hoisting and placement of the prefabricated components. The left-right limiting mechanisms enable simultaneous limitation of the left and right sides of the prefabricated component; the front-back limiting mechanisms precisely limit the front-back position of the prefabricated component. This provides precise positioning for the hoisting and placement of prefabricated components, reducing the number of manual adjustments and the time required, thereby improving installation efficiency.

[0024] 2. Compared with existing technologies, this prefabricated component precision docking and positioning device for prefabricated buildings, by using a binocular camera, can capture the position information of the prefabricated components in real time, and accurately calculate the deviation between the prefabricated components and the predetermined installation position through image processing and analysis technology. This function provides operators with intuitive visual feedback, enabling them to adjust the position of the prefabricated components in a timely manner to ensure precise alignment with the steel bars on the building's foundation slab.

[0025] 3. Compared with existing technologies, this prefabricated component precision docking and positioning device for prefabricated buildings, through the setting of a clamping mechanism, uses a motor to drive the third bidirectional threaded rod to rotate, causing two symmetrically distributed clamping blocks to move simultaneously towards the center or both sides, thereby achieving tight clamping or loosening of the prefabricated component. Simultaneously, the clamping blocks, the third moving rod, the guide block, the guide frame, the spring, the transmission rod, the L-shaped rod, and the clamping plate work together to achieve multi-directional clamping and fixing of the prefabricated component, further improving the stability of the prefabricated component during hoisting.

[0028] Reference Figure 1-8 The present invention provides a precise docking and positioning device for prefabricated building components, comprising a building base plate 1, a moving mechanism 2 provided on the upper end of the building base plate 1, a left and right limiting mechanism 3 provided on the moving mechanism 2, a front and rear limiting mechanism 4 provided on the left and right limiting mechanism 3, and a prefabricated component 5 provided inside the left and right limiting mechanism 3 and the front and rear limiting mechanism 4. The left and right limiting mechanism 3 is used to limit the left and right position of the prefabricated component 5, and the front and rear limiting mechanism 4 is used to limit the front and rear position of the prefabricated component 5. A positioning groove 10 is opened on the lower end face of the prefabricated component 5, and a steel bar 8 is fixedly connected to the upper end of the building base plate 1. The steel bar 8 cooperates with the positioning groove 10. A hanger 6 is provided on the upper end of the prefabricated component 5, and a clamping mechanism 7 is provided inside the hanger 6. The clamping mechanism 7 is used to clamp the prefabricated component 5.

[0029] In use, the moving mechanism 2 is installed on the upper part of the building base slab 1. Then, the moving mechanism 2 is used to move the left and right limiting mechanisms 3 and the front and rear limiting mechanisms 4 to the corresponding positions of the reinforcing bars 8. Subsequently, the precast component 5 is hoisted to the designated area, and the precast component 5 is firmly clamped by the clamping mechanism 7 on the hanger 6 to ensure its stability during hoisting. At this time, the left and right limiting mechanisms 3 are adjusted so that they accurately fit the left and right sides of the precast component 5. After adjusting the left and right limiting mechanisms 3, the front and rear limiting mechanisms 4 are adjusted to accurately position the front and rear of the precast component 5, ensuring that the precast component 5 is precisely aligned with the reinforcing bars 8 on the building base slab 1. This makes the hoisting and positioning of the precast component 5 more convenient and faster, thereby improving installation efficiency.

[0030] The moving mechanism 2 includes a mounting plate 201, an electric telescopic rod 202, a moving frame 203, a slider 204, and a slide rail 205. The mounting plate 201 is fixedly connected to the upper end of the building base plate 1. The electric telescopic rod 202 and the slide rail 205 are fixedly connected to the upper end of the mounting plate 201. There are two slide rails 205, which are symmetrically distributed on both sides of the upper end of the mounting plate 201. The extended end of the electric telescopic rod 202 is fixedly connected to the moving frame 203. The lower end of the moving frame 203 is fixedly connected to the slider 204. The slider 204 and the slide rail 205 are slidably connected. When in use, the electric telescopic rod 202 is activated, and the extended end of the electric telescopic rod 202 will push the moving frame 203 to move. Since the lower end of the moving frame 203 is fixedly connected to the slider 204, and the slider 204 is slidably connected to the slide rail 205, the moving frame 203 can move smoothly under the guidance of the slide rail 205, thereby driving the left and right limiting mechanism 3 and the front and rear limiting mechanism 4 to move to the position corresponding to the steel bar 8, so as to prepare for the subsequent hoisting and placement of the precast component 5.

[0031] The left and right limiting mechanism 3 includes a first bidirectional threaded rod 301, a first moving rod 302, a first handle 303, a first limiting frame 304, and a first rotating roller 305. The first bidirectional threaded rod 301 is rotatably connected inside the moving frame 203. The first handle 303 is fixedly connected to the end of the first bidirectional threaded rod 301. The first moving rod 302 is threadedly connected to the first bidirectional threaded rod 301. The first limiting frame 304 is fixedly connected to the upper end of the first moving rod 302. The first rotating roller 305 is rotatably connected inside the first limiting frame 304. There are two first moving rods 302, which are symmetrically distributed on the first bidirectional threaded rod 301. The internal threads of the two first moving rods 302 have opposite directions.

[0032] In use, rotating the first handle 303 causes the first bidirectional threaded rod 301 to rotate. Since the first bidirectional threaded rod 301 is threadedly connected to the first moving rod 302, its rotation drives the first moving rod 302, which in turn moves the first limiting frame 304. The first limiting frame 304 has a first rotating roller 305 rotatably connected inside. The first rotating roller 305 reduces friction with the precast component 5, facilitating its descent. By adjusting the position of the first limiting frame 304, it can accurately fit the left and right sides of the precast component 5, thus limiting its left and right positions. Simultaneously, because the internal threads of the two first moving rods 302 are in opposite directions, they move simultaneously in opposite directions, causing the two first limiting frames 304 to move simultaneously towards the center or sides, achieving synchronous limitation of the left and right sides of the precast component 5 and improving the accuracy and efficiency of the limitation.

[0033] The front and rear limiting mechanism 4 includes a mounting frame 401, a second bidirectional threaded rod 402, a second handle 403, a second moving rod 404, a second limiting frame 405, and a second rotating roller 406. The mounting frame 401 is fixedly connected to the outer side of the first limiting frame 304. The second bidirectional threaded rod 402 is rotatably connected inside the mounting frame 401. The second handle 403 is fixedly connected to the end of the second bidirectional threaded rod 402. The second moving rod 404 is threadedly connected to the second bidirectional threaded rod 402. The end of the second moving rod 404 away from the second bidirectional threaded rod 402 is fixedly connected to the second limiting frame 405. The second rotating roller 406 is rotatably connected inside the second limiting frame 405. Two second moving rods 404 are provided and symmetrically distributed on the second bidirectional threaded rod 402, with the internal threads of the two second moving rods 404 having opposite directions.

[0034] In use, rotating the second handle 403 causes the second bidirectional threaded rod 402 to rotate. Since the second bidirectional threaded rod 402 is threadedly connected to the second moving rod 404, its rotation drives the second moving rod 404, which in turn moves the second limiting frame 405. The second limiting frame 405 has a rotatably connected second rotating roller 406 inside. The second rotating roller 406 reduces friction with the precast component 5, facilitating its descent. By adjusting the position of the second limiting frame 405, it can accurately fit the front and rear sides of the precast component 5, thus limiting its position. Simultaneously, because the internal threads of the two second moving rods 404 are in opposite directions, when the second bidirectional threaded rod 402 rotates, the two second moving rods 404 move simultaneously in opposite directions, causing the two second limiting frames 405 to move simultaneously towards the center or sides. This improves the accuracy of the limiting and construction efficiency.

[0035] A binocular camera 9 is fixedly connected to the upper end of the mobile frame 203, and the binocular camera 9 is located in the middle of the upper end of the mobile frame 203. In use, the binocular camera 9 can capture the position information of the prefabricated component 5 in real time, and accurately calculate the deviation between the prefabricated component 5 and the predetermined installation position through image processing and analysis technology.

[0036] The clamping mechanism 7 includes a third bidirectional threaded rod 701, a motor 702, and a clamping member 703. The third bidirectional threaded rod 701 is rotatably connected inside the hanger 6. The clamping member 703 is threadedly connected to the third bidirectional threaded rod 701. There are two clamping members 703, which are symmetrically distributed on the third bidirectional threaded rod 701. The motor 702 is fixedly connected to the side end of the hanger 6. The output end of the motor 702 is fixedly connected to the third bidirectional threaded rod 701.

[0037] In use, the motor 702 is started, and its output drives the third bidirectional threaded rod 701 to rotate. Since the third bidirectional threaded rod 701 has two symmetrically distributed clamping members 703 connected by threads, and the internal threads of the two clamping members 703 are in opposite directions, the rotation of the third bidirectional threaded rod 701 drives the two clamping members 703 to move simultaneously towards the center or sides. When it is necessary to clamp the precast component 5, the motor 702 drives the third bidirectional threaded rod 701 to rotate, causing the two clamping members 703 to move simultaneously towards the center, thus tightly clamping the precast component 5 and ensuring its stability during hoisting. When it is necessary to release the precast component 5, the motor 702 rotates in the opposite direction, driving the third bidirectional threaded rod 701 to rotate in the opposite direction, causing the two clamping members 703 to move simultaneously to the sides, thus releasing the precast component 5.

[0038] The clamping component 703 includes a clamping block 7031, a third moving rod 7032, a guide block 7033, a guide frame 7034, a spring 7035, a transmission rod 7036, an L-shaped rod 7037, and a clamping plate 7038. The clamping block 7031 is threaded onto the third bidirectional threaded rod 701. The clamping block 7031 is slidably connected to the hanger 6. The third moving rod 7032 is slidably connected inside the clamping block 7031. The end of the third moving rod 7032 furthest from the precast component 5 is rotatably connected to the transmission rod 7036. An L-shaped rod 7037 is rotatably connected to the end of 7036 away from the moving rod. The L-shaped rod 7037 is slidably connected to the clamping block 7031. A clamping plate 7038 is fixedly connected to the end of the L-shaped rod 7037. The clamping plate 7038 is located at the front and rear ends of the precast component 5. A guide frame 7034 is fixedly connected to the side end of the clamping block 7031. A guide block 7033 is slidably connected to the guide frame 7034. The guide block 7033 is fixedly connected to the third moving rod 7032. A spring 7035 is provided on the guide frame 7034.

[0039] In use, as the clamping block 7031 moves toward the precast component 5, it also drives the third moving rod 7032 to move. After the third moving rod 7032 contacts the precast component 5, it will be squeezed to move, and then, with the cooperation of the transmission rod 7036, it will drive the L-shaped rod 7037 to move. As the L-shaped rod 7037 moves, it also drives the clamping plate 7038 to move toward the precast component 5. In this way, with the cooperation of the clamping block 7031 and the clamping plate 7038, the precast component 5 can be clamped and fixed in multiple directions, thereby improving the stability of the clamping of the precast component 5. At the same time, the movement of the third moving rod 7032 also drives the guide block 7033 to slide on the guide frame 7034, thereby compressing the spring 7035. The compressed spring 7035 is conducive to the reset of the third moving rod 7032.
