Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, and in particular to a rapid positioning and installation device for prefabricated components used in prefabricated buildings. Background Technology

[0002] In the construction of prefabricated buildings, the hoisting and positioning of precast components (such as wall panels, beams, and columns) is a crucial step determining construction efficiency and quality. Traditional precast component installation often relies on tower cranes and manual labor for rough positioning, resulting in low installation accuracy, difficulty in adjustment, and long construction cycles. Especially in fine-tuning the component's posture (such as horizontality, verticality, and rotation angle), existing equipment often lacks precise multi-dimensional adjustment capabilities, making it difficult to quickly and accurately align components to the installation point. This easily leads to "misaligned holes" or "difficulty in placement," increasing the labor intensity of workers and potentially affecting the safety of structural connections due to repeated adjustments. Furthermore, existing auxiliary installation equipment is mostly fixed or has a limited adjustment range, making it difficult to adapt to precast components of different sizes, weights, and shapes, resulting in poor versatility. Therefore, there is an urgent need for a rapid positioning and installation device that integrates movement, lifting, posture adjustment, and automatic clamping functions to achieve full automation and high-precision control of the entire process from grabbing and transporting precast components to precise installation. Therefore, we propose a rapid positioning and installation device for precast components in prefabricated buildings. Summary of the Invention

[0003] The main objective of this invention is to provide a rapid positioning and installation device for prefabricated components in prefabricated buildings, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A rapid positioning and installation device for prefabricated components used in prefabricated buildings, including: A mobile frame, the bottom of which is equipped with self-locking casters; The lifting mechanism is vertically mounted on the movable frame; The gripping mechanism is movably connected to the bottom of the lifting mechanism and is used to clamp the prefabricated component; An angle adjustment mechanism is provided between the lifting mechanism and the gripping mechanism to adjust the spatial posture of the gripping mechanism.

[0005] As a further improvement to the above solution, two columns are symmetrically installed on the mobile frame, and guide grooves are provided on both columns; the lifting mechanism includes a lifting body that is slidably connected to the columns and a first forward and reverse motor that is fixedly installed on the top of the mobile frame. The output end of the first forward and reverse motor is fixedly connected to a transmission screw, and the transmission screw is threadedly connected to the lifting body.

[0006] The above solution uses a forward and reverse motor to drive the transmission screw, which in turn drives the lifting body to slide along the column guide groove. This enables the gripping mechanism to automatically grab precast components from below and achieve fully automated lifting operations. This not only improves work efficiency but also avoids the problem of unstable positioning caused by slack wire ropes in traditional hoisting, significantly enhancing construction safety and controllability.

[0007] As a further improvement to the above solution, the lifting body includes a support frame, the rear of which is provided with a connecting groove adapted to the column, the support frame is slidably connected to the two columns through the connecting groove, and the rear center of the support frame is integrally formed with a transmission arm that is threadedly connected to the transmission screw.

[0008] The above solution utilizes a connecting groove to slide with the column, improving the overall stability of the lifting body during the lifting process and reducing the risk of prefabricated components swaying during lifting.

[0009] As a further improvement to the above solution, two extension arms are symmetrically installed at the lower end of the support frame; the gripping mechanism includes two rotating frames rotatably connected to the bottom of the extension arms, and two crossbeams are fixedly connected to the bottom of the two rotating frames. The two crossbeams are distributed in a front-to-back manner, and a sliding groove is provided at the upper end of each of the two crossbeams. A gripping body is slidably connected between the two crossbeams through the sliding groove.

[0010] As a further improvement to the above solution, the gripping body includes two clamping components symmetrically slidably connected to two crossbeams and a second forward and reverse motor fixedly installed on the outer surface of one of the crossbeams. The output end of the second forward and reverse motor is fixedly connected to a first forward and reverse lead screw, which is movably installed in a slide groove and threadedly connected to the two clamping components.

[0011] The above scheme utilizes a No. 2 forward and reverse motor and a No. 1 forward and reverse lead screw to drive the two clamping components to move synchronously, thereby achieving rapid positioning of the precast component in the width direction.

[0012] As a further improvement to the above solution, the clamping assembly includes a support arm slidably connected between two crossbeams, a longitudinal clamping member is provided on the support arm, and a sliding sleeve that is slidably connected to the crossbeam is fixedly welded to both sides of the support arm. A slider that is slidably connected to the slide groove is integrally formed on the sliding sleeve, and one of the sliders is threadedly connected to a first positive and negative lead screw.

[0013] The above solution utilizes a U-shaped sliding sleeve design to improve the smoothness of the support arm's sliding on the crossbeam. Simultaneously, the T-shaped slider provides an anti-disengagement effect, further enhancing the stability of the support arm during movement.

[0014] As a further improvement to the above solution, the longitudinal clamping member includes two clamping arms symmetrically slidably sleeved on the support arm and a No. 3 forward and reverse motor fixedly installed on the outside of the support arm. The output end of the No. 3 forward and reverse motor is fixedly connected to the No. 2 forward and reverse lead screw, and a connecting block that is threadedly connected to the No. 2 forward and reverse lead screw is fixedly welded to the clamping arm.

[0015] The above solution involves adjusting the longitudinal position of the clamping arm using a No. 3 forward / reverse motor and a No. 2 forward / reverse lead screw, achieving precise positioning in the length direction, efficient adjustment, and adaptability to the installation needs of various component specifications.

[0016] As a further improvement to the above scheme, the threads on both sides of the outer surface of the No. 2 positive and negative lead screw and the No. 1 positive and negative lead screw are of opposite structure.

[0017] The above solution utilizes the characteristics of high-precision threaded transmission, ensuring not only smooth movement and accurate control, but also excellent self-locking performance. It can reliably maintain its current position when power is cut off or the drive stops, ensuring the safety and reliability of the construction process.

[0018] As a further improvement to the above solution, the angle adjustment mechanism includes a drive motor fixedly mounted on the extension arm and a connecting rod fixedly connected between two rotating frames. The output end of the drive motor is fixedly connected to a rotating rod, which is movably connected to the extension arm via a bearing. A drive gear is fixedly connected to the rotating rod, and a transmission gear that meshes with the drive gear is fixedly connected to the connecting rod.

[0019] The above solution utilizes a drive motor and gear set to achieve the overall rotation of the gripping mechanism, thereby flexibly and accurately adjusting the spatial posture of the prefabricated components. It is particularly suitable for installation scenarios with inclined walls or complex nodes, significantly improving positioning accuracy and construction adaptability.

[0020] As a further improvement to the above solution, the connecting rod is movably connected to the two extension arms via bearings.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through the design of the lifting mechanism, uses a No. 1 forward and reverse motor to drive the transmission screw to move the lifting body along the column guide groove, realizing the automatic grabbing of prefabricated components from below and the fully automated lifting operation. This not only improves work efficiency, but also avoids the problem of unstable positioning caused by slack wire ropes in traditional hoisting, and significantly enhances construction safety and controllability.

[0022] 2. This invention utilizes a multi-stage adjustable structure design for the gripping mechanism, employing a second forward and reverse motor and a first forward and reverse lead screw to drive the two clamping components to move synchronously, thereby achieving rapid positioning of the precast component in the width direction. Simultaneously, the third forward and reverse motor and the second forward and reverse lead screw adjust the longitudinal position of the clamping arm to achieve precise positioning in the length direction. The overall structure provides stable clamping, efficient adjustment, and adaptability to the installation requirements of components of various specifications.

[0023] 3. This invention sets up an angle adjustment mechanism between the lifting mechanism and the gripping mechanism, and uses a drive motor and gear set (drive gear and transmission gear) to realize the overall rotation of the gripping mechanism, thereby flexibly and accurately adjusting the spatial posture of the prefabricated components. It is especially suitable for installation scenarios with inclined walls or complex nodes, and greatly improves the positioning accuracy and construction adaptability.

[0024] 4. This invention employs a screw drive system for both clamping and height adjustment. Utilizing the high-precision thread transmission characteristics of the drive screw and the forward and reverse screws (No. 2 forward and reverse screw and No. 1 forward and reverse screw), it not only ensures the smoothness of movement and the accuracy of control, but also possesses excellent self-locking performance. It can reliably maintain its current position when power is cut off or the drive stops, preventing the component from sliding down due to gravity and ensuring the safety and reliability of the construction process.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0032] Prefabricated component rapid positioning and installation device for prefabricated buildings, such as Figure 1-8 As shown, it includes: The mobile frame 1 is equipped with self-locking casters 2 at its bottom; The lifting mechanism 3 is vertically mounted on the movable frame 1; The gripping mechanism 4 is movably connected to the bottom of the lifting mechanism 3 and is used to clamp the prefabricated components; An angle adjustment mechanism 5 is located between the lifting mechanism 3 and the gripping mechanism 4, and is used to adjust the spatial posture of the gripping mechanism 4.

[0033] In this embodiment, two columns are symmetrically installed on the mobile frame 1, and each column has a guide groove 11. The lifting mechanism 3 includes a lifting body 31 that is slidably connected to the columns and a first forward and reverse motor 32 that is fixedly installed on the top of the mobile frame 1. The output end of the first forward and reverse motor 32 is fixedly connected to a transmission screw 33, and the transmission screw 33 is threadedly connected to the lifting body 31. The lifting body 31 includes a support frame 311. The rear part of the support frame 311 has a connecting groove 312 that is adapted to the columns. The support frame 311 is slidably connected to the two columns through the connecting groove 312. The rear middle part of the support frame 311 has an integrally formed transmission arm 313 that is threadedly connected to the transmission screw 33.

[0034] Through the above scheme: The first forward and reverse motor 32 in the lifting mechanism 3 is activated. The motor drives the transmission screw 33 to rotate, causing the lifting body 31, which is threadedly connected to it, to smoothly rise and fall along the guide groove 11 on the column until the grabbing mechanism 4 moves to a height suitable for grabbing. By designing the lifting mechanism 3, using the first forward and reverse motor 32 to drive the transmission screw 33 to move the lifting body 31 along the guide groove 11 on the column, the grabbing mechanism 4 automatically grabs precast components from below and performs fully automated lifting operations. This not only improves work efficiency but also avoids the problem of unstable positioning caused by slack wire ropes in traditional hoisting, significantly enhancing construction safety and controllability.

[0035] In this embodiment, two extension arms 314 are symmetrically installed at the lower end of the support frame 311; the gripping mechanism 4 includes two rotating frames 41 rotatably connected to the bottom of the extension arms 314, and two crossbeams 42 are fixedly connected to the bottom of the two rotating frames 41. The two crossbeams 42 are distributed front and back, and each of the two crossbeams 42 has a sliding groove 43 at its upper end. A gripping body 44 is slidably connected between the two crossbeams 42 through the sliding groove 43; the gripping body 44 includes two clamping components 47 symmetrically slidably connected to the two crossbeams 42 and a second forward and reverse motor 45 fixedly installed on the outer surface of one of the crossbeams 42. A first forward and reverse lead screw 46 is fixedly connected to the output end of the second forward and reverse motor 45. The first forward and reverse lead screw 46 is movably installed in the sliding groove 43 and threadedly connected to the two clamping components 47; the clamping components 47 include two clamping components slidably connected to the two crossbeams 42. A support arm 471 is located between the two crossbeams 42. A longitudinal clamping member 474 is provided on the support arm 471. Sliding sleeves 472 that are slidably connected to the crossbeams 42 are fixedly welded to both sides of the support arm 471. A slider 473 that is slidably connected to the sliding groove 43 is integrally formed on the sliding sleeve 472. One of the sliders 473 is threadedly connected to the first positive and negative lead screw 46. The longitudinal clamping member 474 includes two clamping arms 477 that are symmetrically slidably sleeved on the support arm 471 and a third positive and negative motor 475 that is fixedly installed on the outside of the support arm 471. The output end of the third positive and negative motor 475 is fixedly connected to the second positive and negative lead screw 476. A connecting block 478 that is threadedly connected to the second positive and negative lead screw 476 is fixedly welded to the clamping arm 477. The threads on both sides of the outer surface of the second positive and negative lead screw 476 and the first positive and negative lead screw 46 are reversed.

[0036] Through the above scheme: the first forward and reverse motor 32 in the lifting mechanism 3 is started, the motor drives the transmission screw 33 to rotate, and drives the lifting body 31, which is threaded to it, to rise and fall smoothly along the guide groove 11 on the column until the gripping mechanism 4 moves to a height that is easy to grip. Then, the second forward and reverse motor 45 in the gripping mechanism 4 drives the first forward and reverse screw 46 to rotate, so that the two clamping components 47 slide synchronously towards or away from each other, and adjust the clamping distance to adapt to the width of the prefabricated component. At the same time, the third forward and reverse motor 475 drives the second forward and reverse screw 476 to adjust the position of the clamping arm 477 in the longitudinal direction, thereby realizing flexible clamping of components of different sizes. Through the multi-stage adjustment structure design of the gripping mechanism 4, the two clamping components 47 are driven to move synchronously by the No. 2 forward and reverse motor 45 and the No. 1 forward and reverse lead screw 46, so as to achieve rapid positioning of the prefabricated component in the width direction; at the same time, the longitudinal position of the clamping arm 477 is adjusted by the No. 3 forward and reverse motor 475 and the No. 2 forward and reverse lead screw 476 to complete the precise positioning in the length direction. The overall structure is stable in clamping and efficient in adjustment, and can adapt to the installation requirements of components of various specifications.

[0037] In this embodiment, the angle adjustment mechanism 5 includes a drive motor 51 fixedly mounted on the extension arm 314 and a connecting rod 54 fixedly connected between two rotating frames 41. The output end of the drive motor 51 is fixedly connected to a rotating rod 52. The rotating rod 52 is movably connected to the extension arm 314 through a bearing. A drive gear 53 is fixedly connected to the rotating rod 52. A transmission gear 55 that meshes with the drive gear 53 is fixedly connected to the connecting rod 54. The connecting rod 54 is movably connected to the two extension arms 314 through a bearing.

[0038] With the above scheme: once the clamping position is determined, the drive motor 51 drives the drive gear 53 to rotate via the rotating rod 52, and the transmission gear 55 meshing with it rotates accordingly, driving the connecting rod 54 and the entire gripping mechanism 4 to rotate around the axis of the rotating rod, thereby realizing the adjustment of the pitch angle of the precast component in the vertical plane. By setting an angle adjustment mechanism 5 between the lifting mechanism 3 and the gripping mechanism 4, the overall rotation of the gripping mechanism 4 is realized by the drive motor 51 and the gear set (drive gear 53 and transmission gear 55), thereby flexibly and accurately adjusting the spatial posture of the precast component. This is especially suitable for installation scenarios with inclined walls or complex nodes, greatly improving positioning accuracy and construction adaptability.

[0039] It should be noted that this invention is a rapid positioning and installation device for prefabricated components in prefabricated buildings. During use, firstly, the operator pushes the mobile frame 1 to the prefabricated component stacking position; after reaching the designated position, the operator operates and locks the self-locking casters 2 installed at the bottom of the mobile frame 1, firmly fixing the equipment on a horizontal surface to form a rigid support foundation, preventing displacement or shaking of the equipment during subsequent operations; next, the first forward and reverse motor 32 in the lifting mechanism 3 is started, and the motor output shaft drives the transmission screw 33 to rotate; since the lifting body 31 and the transmission screw 33 are connected by a threaded pair, and the lifting body 31 is limited to linear movement by the guide groove 11 on the column, the rotational movement of the transmission screw 33 is converted into the smooth vertical lifting and lowering of the lifting body 31 along the guide groove 11; the lifting body 31 drives the gripping mechanism 4 at its front end to rise or fall until the gripping mechanism 4 moves to a height position matching the gripping point of the prefabricated component; then, the gripping mechanism 4 is activated. The second forward / reverse motor 45 drives the first forward / reverse lead screw 46 to rotate. Since the two clamping components 47 are threadedly connected to the two oppositely threaded sections of the first forward / reverse lead screw 46, the rotation of the first forward / reverse lead screw 46 drives the two clamping components 47 to slide synchronously towards each other (clamping) or towards each other (releasing), thereby adjusting the clamping distance to accommodate the gripping needs of prefabricated components of different widths. Simultaneously or subsequently, the third forward / reverse motor 475 drives the second forward / reverse lead screw 476 to rotate. The second forward / reverse lead screw 476 drives the clamping arm 477, which is threaded to it, to slide along the longitudinal guide rail, adjusting the extension length of the clamping arm 477 in the longitudinal direction, thereby achieving flexible clamping and fine-tuning of the center position for components of different lengths. Once the clamping position and spacing are determined, the... The drive motor 51 in the angle adjustment mechanism 5 drives the rotating rod 52 to rotate via a coupling. The drive gear 53 at the end of the rotating rod 52 rotates accordingly and meshes with the transmission gear 55 fixedly installed on the side wall of the gripping mechanism 4. Driven by the drive gear 53, the transmission gear 55 rotates around the axis of the rotating rod 52, and then drives the entire gripping mechanism 4 and the precast component being gripped to adjust the pitch angle in the vertical plane around the axis of the rotating rod via the connecting rod 54. Finally, the lifting mechanism 3 is activated again to lift the precast component with the gripped and adjusted posture to the installation design height. When approaching the installation position, the angle adjustment mechanism 5 is used for fine posture adjustment to eliminate installation errors and make the connection hole of the precast component accurately aligned with the main structure to complete the installation operation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
