A prefabricated composite slab hoisting construction device

Abstract

This utility model relates to the technical field of prefabricated composite slab hoisting construction device, and discloses a prefabricated composite slab hoisting construction device, including a lifting beam and a composite slab body. A support frame is provided on the front surface of the lifting beam, and a connecting plate is fixedly connected to the inner wall of the support frame. Through the set hoisting clamping components, a first motor drives the lead screw to rotate, which drives the positioning plate to rise and fall stably along the guide rod. It can be lowered to a low position for easy placement of the composite slab body, and can also be accurately raised to a designated position according to the construction height. There is no need to frequently adjust the hoisting height of external lifting equipment, which reduces the difficulty of operation and improves efficiency.

No separate configuration device is required, which greatly expands the scope of application. The two work together through vertical adjustment and horizontal adaptation to optimize the hoisting process and meet diverse construction needs.

Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated composite slab hoisting construction device, and in particular to a prefabricated composite slab hoisting construction device. Background Technology

[0002] The prefabricated composite slab hoisting and construction device is a core piece of equipment designed specifically for prefabricated building construction. It is mainly used to transfer prefabricated composite slabs (concrete components that combine prefabricated and cast-in-place layers) from the storage site or transport vehicle to the designated installation position on the construction site. It is a key tool connecting the production of prefabricated components with on-site assembly, and can greatly improve the efficiency and safety of prefabricated building construction.

[0003] The applicant discovered through a search that a Chinese patent, "A Lifting and Positioning Device for Prefabricated Composite Slabs in Building Construction," with publication number "CN220131734U," discloses a device that uses a positioning frame, mounting groove, limiting column, sliding assembly, and positioning mechanism. The composite slab is placed on the positioning frame and fixed by the positioning mechanism, thus achieving positioning. A steel wire rope pulls the positioning frame upwards, lifting the composite slab. During lifting, the sliding assembly moves upwards along the limiting column, preventing the steel wire rope from swaying and ensuring the positioning frame remains vertical. The device is raised upwards to stably hoist the composite slab, solving the problem of instability caused by the swaying of the wire rope during hoisting. However, this patent only fixes the composite slab to the positioning frame through a positioning mechanism and does not mention an adjustment structure for the width of the composite slab. The fixing method is limited to load-bearing positioning. In actual use, it cannot be adapted to composite slabs of different widths. If the width of the composite slab does not match the size of the positioning frame, a separate positioning frame needs to be customized, increasing the equipment investment cost and limiting the applicable scenarios. Therefore, we propose a prefabricated composite slab hoisting construction device. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated composite slab hoisting construction device to solve the problems mentioned in the background art, which only fixes the composite slab to the positioning frame through the positioning mechanism, without mentioning the adjustment structure for the width of the composite slab. The fixing method is limited to load-bearing positioning, which cannot be adapted to composite slabs of different widths in actual use. If the width of the composite slab does not match the size of the positioning frame, a positioning frame needs to be customized separately, which increases the equipment investment cost and limits the applicable scenarios.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated composite slab hoisting construction device, comprising a hoisting beam and a composite slab body, a support frame is provided on the front surface of the hoisting beam, a connecting plate is fixedly connected to the inner wall of the support frame, a hoisting clamping assembly is provided inside the support frame, the hoisting clamping assembly includes a first motor, a guide rod and a second motor, the first motor is connected to a positioning plate through a lead screw, a slide rail is provided on the surface of the positioning plate, the second motor is connected to a moving block and a clamping plate through a bidirectional screw, a sliding seat is fixedly connected to the bottom rear side of the clamping plate, and the sliding seat is slidably connected to the inside of the slide rail.

[0006] As a preferred embodiment, the first motor is fixedly installed on the inner left bottom wall of the support frame, the lower end of the lead screw is fixedly connected to the output end of the first motor, the upper end of the lead screw is rotatably connected to the inner top wall of the support frame, and the outer wall of the lead screw is rotatably connected to the inside of the connecting plate.

[0007] As a preferred embodiment, the lower end of the guide rod is fixedly connected to the top right side of the connecting plate, the upper end of the guide rod is fixedly connected to the inner top wall of the support frame, the left end of the positioning plate is threaded to the outer wall of the lead screw, the right end of the positioning plate is slidably connected to the outer wall of the guide rod, and the main body of the composite plate is disposed on the surface of the positioning plate.

[0008] As a preferred embodiment, the second motor is fixedly installed on the left outer wall of the positioning plate, one end of the bidirectional screw is fixedly connected to the output end of the second motor, the other end of the bidirectional screw is rotatably connected to the right inner wall of the positioning plate, the inner wall of the moving block is threadedly connected to the outer wall of the bidirectional screw, and the moving block is fixedly connected to the bottom front side of the clamping plate.

[0009] As a preferred embodiment, the top of the clamping plate is provided with a clamping assembly, the clamping assembly includes a load-bearing block, the load-bearing block is fixedly connected to the top of the clamping plate, an electro-hydraulic rod is fixedly installed on the top of the load-bearing block, and a pressure plate is fixedly connected to the lower end of the electro-hydraulic rod.

[0010] As a preferred embodiment, a rubber pad is fixedly connected to the bottom of the pressure plate, a fixing rod is fixedly connected to the top of the pressure plate, the outer wall of the fixing rod is slidably connected to the inner wall of the load-bearing block, and a limit block is fixedly connected to the upper end of the fixing rod.

[0011] The technical effects and advantages of this utility model are as follows: Through the set hoisting and clamping components, the first motor drives the lead screw to rotate, which can drive the positioning plate to slide stably up and down along the guide rod. This can lower the positioning plate to a low position for easy placement of the composite slab body, and can also accurately lift it to the designated position according to the construction height. This eliminates the need to rely on external lifting equipment for frequent height adjustments, reducing operational difficulty and improving hoisting efficiency. At the same time, the second motor drives the bidirectional screw to rotate, which drives the two sets of moving blocks to move towards or away from each other, thereby pushing the two sets of clamping plates to move closer or further away synchronously. The clamping plate spacing can be flexibly adjusted according to the width of the composite slab body to achieve stable clamping. There is no need to configure separate devices for composite slabs of different widths, which greatly expands the applicability. The two components, through the synergy of vertical adjustment and horizontal adaptation, further optimize the hoisting process and meet diverse construction needs. With the set clamping components, the electric hydraulic rod can drive the pressure plate to press down on the composite slab body, forming a stable fixation in the vertical direction. This effectively restricts the up-and-down movement of the composite slab body during hoisting, improving the reliability of the fixation. In addition, the rubber pad fixed at the bottom of the pressure plate is in direct contact with the composite slab body. By utilizing the flexibility of the rubber material, it can avoid hard contact between the metal pressure plate and the composite slab body, thereby reducing problems such as scratches on the surface of the composite slab body and edge cracking. While strengthening the vertical fixation effect, it also ensures the integrity of the prefabricated components. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 Appendix Figure 3 and appendix Figure 4 A prefabricated composite slab hoisting construction device includes a hoisting beam 1 and a composite slab body 6. A support frame 2 is provided on the front surface of the hoisting beam 1. A connecting plate 3 is fixedly connected to the inner wall of the support frame 2. A hoisting clamping assembly 4 is provided inside the support frame 2. The hoisting clamping assembly 4 includes a first motor 401, a guide rod 404 and a second motor 406. The first motor 401 is connected to a positioning plate 403 through a lead screw 402. A slide rail 405 is provided on the surface of the positioning plate 403. The second motor 406 is connected to a moving block 408 and a clamping plate 409 through a bidirectional screw 407. A slide seat 410 is fixedly connected to the bottom rear side of the clamping plate 409. The slide seat 410 is slidably connected to the inside of the slide rail 405.

[0016] The first motor 401 is the vertical drive source of the hoisting and clamping assembly 4. It is fixed to the bottom left wall inside the support frame 2. It drives the lead screw 402 to rotate through the output end, providing power for the lifting and lowering of the positioning plate 403. The composite plate body 6 is the hoisting object of the device. It is placed on the surface of the positioning plate 403 and clamped and fixed by two sets of clamping plates 409. With the movement and lifting of the hoisting beam 1 and the positioning plate 403, it realizes the transfer from the storage point to the construction and installation position.

[0017] The first motor 401 is fixedly installed on the bottom left side of the support frame 2. The lower end of the lead screw 402 is fixedly connected to the output end of the first motor 401. The upper end of the lead screw 402 is rotatably connected to the top wall of the support frame 2. The outer wall of the lead screw 402 is rotatably connected to the inside of the connecting plate 3. The lower end of the guide rod 404 is fixedly connected to the top right side of the connecting plate 3. The upper end of the guide rod 404 is fixedly connected to the top wall of the support frame 2. The left end of the positioning plate 403 is threaded to the outer wall of the lead screw 402. The right end of the positioning plate 403 is slidably connected to the outer wall of the guide rod 404. The composite plate body 6 is disposed on the surface of the positioning plate 403.

[0018] The slide rail 405 is a horizontal guide structure formed on the surface of the positioning plate 403, which allows the slide block 410 to slide and restricts the horizontal movement trajectory of the two sets of clamping plates 409, ensuring that the two sets of clamping plates 409 always move in opposite directions along a straight line, thus avoiding deviation during clamping.

[0019] The second motor 406 is fixedly installed on the left outer wall of the positioning plate 403. One end of the bidirectional screw 407 is fixedly connected to the output end of the second motor 406, and the other end of the bidirectional screw 407 is rotatably connected to the right inner wall of the positioning plate 403. The inner wall of the moving block 408 is threadedly connected to the outer wall of the bidirectional screw 407, and the moving block 408 is fixedly connected to the bottom front side of the clamping plate 409.

[0020] The movable block 408, clamping plate 409, and slide block 410 are all provided in two sets. Under the action of the bidirectional screw 407, the two sets of clamping plates 409 clamp the composite plate body 6 above the positioning plate 403. A rectangular groove is provided on the front side of the top of the positioning plate 403, which allows the movable block 408 to move left and right.

[0021] Specifically, through the set hoisting and clamping assembly 4, the first motor 401 drives the lead screw 402 to rotate, causing the positioning plate 403 to slide stably up and down along the guide rod 404. This can lower the positioning plate 403 to a low position to place the composite slab body 6, or raise it to a designated position according to the construction height. This eliminates the need to rely on external lifting equipment for frequent height adjustments, reducing operational difficulty and improving hoisting efficiency. At the same time, the second motor 406 drives the bidirectional screw 407 to rotate, causing the two sets of moving blocks 408 to move towards or away from each other, pushing the two sets of clamping plates 409 to move closer or further away synchronously. The spacing of the clamping plates 409 can be adjusted according to the width of the composite slab body 6 to achieve stable clamping. This eliminates the need for separate devices for composite slabs of different widths, expanding the applicability range. Through the synergy of vertical adjustment and horizontal adaptation, the hoisting process is optimized to meet diverse construction needs.

[0022] Please see the appendix Figure 1 Appendix Figure 5 and appendix Figure 6 The top of the clamping plate 409 is provided with a pressing assembly 5, which includes a load-bearing block 501. The load-bearing block 501 is fixedly connected to the top of the clamping plate 409. An electric hydraulic rod 502 is fixedly installed on the top of the load-bearing block 501, and a pressure plate 503 is fixedly connected to the lower end of the electric hydraulic rod 502.

[0023] The fixed rod 505 is a guide component for the lifting and lowering of the pressure plate 503. Its outer wall is slidably connected to the inner wall of the load-bearing block 501. It lifts and lowers synchronously with the pressure plate 503, restricting the movement trajectory of the pressure plate 503 and preventing the pressure plate 503 from deflecting due to uneven driving force of the electric hydraulic rod 502. This ensures that the pressure plate 503 always acts perpendicularly on the composite plate body 6. A rubber pad 504 is fixedly connected to the bottom of the pressure plate 503, and a fixing rod 505 is fixedly connected to the top of the pressure plate 503. The outer wall of the fixing rod 505 is slidably connected to the inner wall of the load-bearing block 501, and a limit block 506 is fixedly connected to the upper end of the fixing rod 505.

[0024] The limiting block 506 is used to limit the downward stroke of the fixed rod 505. When the pressure plate 503 moves downward, the fixed rod 505 slides down with it. The limiting block 506 will contact the top of the load-bearing block 501, preventing the fixed rod 505 from coming out of the load-bearing block 501 and ensuring the connection stability between the fixed rod 505 and the load-bearing block 501.

[0025] Specifically, through the clamping component 5, the electric hydraulic rod 502 drives the pressure plate 503 to press down on the composite slab body 6, forming a vertical fixation, restricting the up-and-down movement of the composite slab body 6 during hoisting, and improving the fixation reliability. The rubber pad 504 fixed at the bottom of the pressure plate 503 directly contacts the composite slab body 6. With the help of the properties of the rubber material, hard contact between the metal pressure plate 503 and the composite slab body 6 is avoided, reducing problems such as scratches on the surface of the composite slab body 6 and edge cracking. While strengthening the vertical fixation effect, the integrity of the precast components is also ensured.

[0026] Working principle of this utility model: This utility model is a prefabricated composite slab hoisting construction device. First, the worker securely connects the lifting beam 1 to the external lifting equipment to ensure the overall suspension stability of the device. Then, the worker starts the first motor 401. The output end of the first motor 401 drives the lead screw 402 to rotate. The left end of the positioning plate 403 slides downward along the outer wall of the lead screw 402, and the right end descends steadily along the outer wall of the guide rod 404. When the positioning plate 403 has descended to a low position, making it convenient for the worker to move the composite slab body 6, the first motor 401 is turned off. Then, the composite slab body 6 is placed stably. On the surface of the positioning plate 403, ensuring the main body 6 of the composite plate is placed in the center, the operator starts the second motor 406. The output end of the second motor 406 drives the bidirectional screw 407 to rotate. The two sets of moving blocks 408 move towards each other along the outer wall of the bidirectional screw 407. The moving blocks 408 drive the two sets of clamping plates 409 to move closer simultaneously. The slide block 410 on the rear side of the bottom of the clamping plate 409 slides along the slide rail 405 on the surface of the positioning plate 403. After the two sets of clamping plates 409 are in close contact with both sides of the main body 6 of the composite plate and form a stable clamp, the second motor 406 is turned off, completing the horizontal fixation of the main body 6 of the composite plate. Then, the work... Personnel activate the electric hydraulic rod 502, which pushes the pressure plate 503 downwards. The fixing rod 505 at the top of the pressure plate 503 slides synchronously along the inner wall of the load-bearing block 501. Once the rubber pad 504 at the bottom of the pressure plate 503 is in close contact with the top of the composite slab body 6 and is vertically fixed, the electric hydraulic rod 502 is deactivated. At this point, the limit block 506 is not in contact with the load-bearing block 501, completing the horizontal and vertical fixation of the composite slab body 6. Personnel then operate external lifting equipment to slowly lift the lifting beam 1, support frame 2, and the fixed composite slab body 6. Simultaneously, according to the construction... To meet the installation height requirements at the construction site, the first motor 401 is restarted, driving the positioning plate 403 to slide upward along the guide rod 404, precisely raising the composite plate body 6 to the designated installation height. The first motor 401 is then turned off. During the lifting process, after the composite plate body 6 is transferred to the construction and installation position and precisely aligned, the workers first start the electric hydraulic rod 502, driving the pressure plate 503 to reset upward. The electric hydraulic rod 502 is then turned off, and the second motor 406 is started in reverse, driving the bidirectional screw 407 to rotate in the opposite direction. The two sets of clamping plates 409 move in opposite directions and detach from the composite plate body 6. The second motor 406 is then turned off.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
