Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a composite slab positioning component and a prefabricated building composite slab construction equipment and method. Background Art

[0002] With the development of the construction industry, prefabricated buildings are increasingly being used in office, residential and other building structures. Large-size prefabricated composite slabs are widely used due to their advantages such as high mass production efficiency, convenient hoisting and installation, and no need for bottom formwork.

[0003] Traditionally, the placement of prefabricated composite slabs involves multiple people using pry bars to adjust the slab's position while it's in place, ensuring it's vertical and its top is level. This facilitates later installation of the top slab. However, this process is cumbersome, lacks precision, and requires repeated fine-tuning by workers, severely impacting assembly efficiency. When a tower crane lifts the composite slab to its designated position, the distance is considerable, leading to significant deviations between the slab and its intended location. This necessitates multiple workers supporting and guiding the slab from below, further hindering installation efficiency. Furthermore, if the ropes connecting the slab break during manual guidance, it poses a safety hazard to workers. Additionally, manual connection and disassembly between the tower crane and the slab are required during the lifting process.

[0004] Therefore, this invention proposes a composite slab positioning component and a construction equipment and method for prefabricated building composite slabs. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing composite slabs, such as the inability to make precise adjustments during assembly, large positioning errors during hoisting, and the need for manual connection and disassembly between tower cranes and composite slabs.

[0007] In one possible design, the adjustment structure includes two base plates fixed to the top of the base plate, with a screw rotatably connected between the two base plates.

In this configuration, the first spring pushes the pressure plate against the top of the composite plate body, the infrared sensor detects the distance of the pressure plate to determine the tilt of the composite plate body, and the screw drives the trapezoidal top block to move so as to lift the composite plate body through the inclined groove and adjust its horizontal state.

[0008] In one possible design, the jacking structure includes a threaded hole on the side of the base plate away from the T-shaped plate, the threaded hole being threadedly connected to a rotating threaded rod; a lead screw is slidably connected inside the rotating cylinder, a nut block is rotatably connected to the top of the rotating cylinder, the nut block being threadedly connected to the lead screw, a second fixing seat is rotatably connected to the top of the lead screw, the second fixing seat being fixedly connected to one side of the composite plate body by screws; an insert plate is fixedly connected to the side of the T-shaped plate near the base plate, the side of the base plate near the T-shaped plate has a slot for inserting and engaging with the insert plate, a plurality of first bolts rotatably pass through the T-shaped plate, the first bolts being threadedly connected to the base plate, and a plurality of pressure sensors are fixedly embedded on the side of the T-shaped plate near the composite plate body; The nut block rotates to drive the lead screw to extend, the second fixed seat pushes against the composite plate body, and the pressure sensor detects the pressure to determine the vertical state.

[0009] In one possible design, a rotating ring is rotatably sleeved on the outer wall of the rotating threaded rod, and a bending guide plate is sleeved on the outer wall of the rotating threaded rod, the bending guide plate being located between the rotating ring and the base plate; a plurality of fixing rods are fixedly connected to the side of the rotating ring near the base plate, and one end of the plurality of fixing rods extends into the bending guide plate; When the rotating threaded rod is connected through the threaded hole, the rotating ring and the base plate clamp the bending guide plate, and the bending guide plate guides the position when the composite plate body moves down.

[0010] In one possible design, pressure plates are fixedly connected to both the top and bottom of the second fixing seat; The pressure plate ensures the uniformity of force on the composite plate body when it is pushed by the second fixed seat.

[0011] The prefabricated building composite slab construction equipment includes a composite slab positioning component as described above, and also includes a U-shaped seat and a connecting column. The top of the U-shaped seat and the bottom of the connecting column are fixedly connected by steel wire ropes. The top of the connecting column is used to connect the ropes of the tower crane. A horizontal plate is slidably connected inside the U-shaped seat. A hoisting structure is provided between the top of the horizontal plate and the top of the composite plate body.

[0012] In one possible design, the hoisting structure includes multiple V-shaped rods fixed to the top of the composite plate body, with a common horizontal bar fixedly passing through the multiple V-shaped rods; the bottom of the horizontal plate is provided with multiple moving slots, and two guide rods are fixedly connected in the multiple moving slots; two moving seats are slidably sleeved on the outer walls of the two guide rods; two second springs are sleeved on the outer walls of the two guide rods; the ends of the two second springs that are close to each other abut against one side of the corresponding moving seat through spring seats, and the ends of the two second springs that are far from each other abut against one side of the inner wall of the moving slot through spring seats; a first hook and a second hook are fixedly connected to the bottom of the two moving seats respectively, and the first hook and the second hook are staggered; an electromagnet is fixedly connected to the side of the two moving seats that are close to each other. The second spring drives the movable seat to move towards the center so that the first hook and the second hook hook onto the crossbar, and the electromagnet generates a repulsive force to drive the movable seat to move to both sides to release the hoisting.

[0013] In one possible design, the top of the cross plate is rotatably connected to a first threaded rod via a base, one end of which is threaded through a U-shaped seat; When the first threaded rod rotates, the relative distance between the horizontal plate and the U-shaped seat is adjusted to finely adjust the position of the composite plate body.

[0014] In one possible design, a triangular strip is fixedly connected to the top of the crossbar; The triangular strip guides the first and second hooks to both sides when the horizontal plate moves down.

[0015] The method of using the prefabricated building composite slab construction equipment in this application includes the following steps: S1. Hook locking procedure: The tower crane moves the horizontal plate to above the composite plate body, so that the horizontal bar is located between the adjacent first hook and second hook; the horizontal plate is moved down, and the first hook and second hook are pushed to the sides to move below the horizontal bar by the triangular strip at its bottom. The first hook and second hook move inward under the action of the return spring and hook the horizontal bar.

[0016] S2. Lifting and Coarse Positioning Steps: The tower crane lifts the composite slab body to above the base plate; the drive motor rotates the threaded rod to finely adjust the position of the horizontal plate so that the guide hole of the composite slab body is aligned with the positioning vertical rod on the base plate; the composite slab body is lowered, and the positioning vertical rod enters through the tapered guide groove and is inserted into the guide hole.

[0017] S3. Peripheral Fixing and Guiding Steps: Fix the side T-shaped plate to the base plate through the plug-in structure; fit the bending guide plate into the threaded rod and screw it into the threaded hole of the fixing seat for fixation; when the composite plate body is lowered, it is limited by the side T-shaped plate and guided by the bending guide plate.

[0018] S4. Horizontal Inspection and Adjustment Steps: Rotate the side rotating arm to fit against the side wall of the composite plate body and lift the inspection pressure plate; release the spring so that the pressure plate protrusion abuts against the top surface of the composite plate body; use the infrared sensor on the pressure plate to detect the distance and determine the horizontality; if tilted, rotate the adjusting screw to drive the trapezoidal top block into the bottom inclined groove to adjust it to horizontal.

[0019] S5. Vertical clamping step: Fix the vertical adjustment fixing seat to the composite plate body; rotate the adjusting nut to drive the push screw to extend, so that the end pressure plate pushes the composite plate body tightly against the side T-shaped plate.

[0020] S6. Verticality detection and fine-tuning steps: The verticality is determined by detecting the pressure distribution through multiple pressure sensors on the side T-plate; the length of the corresponding push screw is finely adjusted to make the pressure distribution uniform, and the final positioning is completed.

[0021] Beneficial effects: In this invention, a screw is rotatably connected between the two substrates. A trapezoidal top block is threaded onto the outer wall of the screw, and a sloping groove engages with the trapezoidal top block. A rotating arm is rotatably connected to one side of the T-shaped plate. A second vertical rod is fixed to the top of the rotating arm. A pressure plate is slidably fitted onto the outer wall of the second vertical rod. An infrared sensor is fixed to the top of the T-shaped plate. A first spring pushes the pressure plate downward, causing a protrusion on one side to abut against the top of the composite plate body. The infrared sensor detects the distance of the pressure plate. Based on the distance detection of the corresponding pressure plates by multiple infrared sensors, it is determined whether the composite plate body is tilted. The screw rotation drives the trapezoidal top block to move. The trapezoidal top block engages with the sloping surface of the sloping groove to lift the composite plate body, thereby ensuring that the top of the composite plate body is in a horizontal state.

[0022] In this invention, the threaded hole is threadedly connected to the rotating threaded rod, a lead screw is slidably connected inside the rotating cylinder, and a nut block threadedly connected to the lead screw is rotatably connected to the top of the rotating cylinder. The second fixed seat is fixedly connected to one side of the composite plate body by screws. An insert plate is fixed to one side of the T-shaped plate, and a slot is provided on the side of the bottom plate near the T-shaped plate. Multiple pressure sensors are fixedly embedded on the side of the T-shaped plate near the composite plate body. The rotation of the nut block drives the lead screw to extend, and the second fixed seat cooperates with the pressure plate to push the composite plate body. The multiple pressure sensors can detect the pressure applied by the composite plate body to the T-shaped plate in real time. Based on the multiple pressure sensors on the multiple T-shaped plates, it can detect whether the composite plate body is in a vertical state, and finely adjust the extension length of the corresponding lead screw, thereby completing the adjustment of the vertical state of the composite plate body.

[0023] In this invention, a rotating ring is rotatably sleeved on the outer wall of the rotating threaded rod, and a bending guide plate is sleeved on the outer wall of the rotating threaded rod. When the composite plate body is hoisted onto the base plate by the tower crane, the T-shaped plate limits the composite plate body, while the bending guide plate guides the composite plate body, avoiding large errors during the hoisting process of the composite plate body.

[0024] In this invention, two guide rods are fixed in the multiple movable slots, and two movable seats are slidably sleeved on the outer walls of the two guide rods. Two second springs are sleeved on the outer walls of the two guide rods. A first hook and a second hook are fixed to the bottom of the two movable seats respectively. An electromagnet is fixed on the side of the two movable seats that are close to each other. The cooperation between the second spring and the first and second hooks can easily hoist the crossbar. When the electromagnet is energized, the repulsive force between the two electromagnets pushes the movable seat to move outward, releasing the hoisting of the crossbar by the first and second hooks. No manual operation is required, which greatly improves the hoisting and assembly efficiency of the composite plate body.

[0025] In this invention, by precisely controlling the horizontal and vertical state and positional fine-tuning of the composite slab body, the installation accuracy and construction efficiency are improved. At the same time, by automatically controlling the hoisting and dismantling process, the difficulty of manual operation and safety risks are reduced. In addition, the component and equipment also have the advantages of stable and reliable structure and simple operation, and are suitable for various prefabricated building construction scenarios.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In one embodiment: Refer to Figures 1-7 and Figure 12 The positioning component relates to the field of building construction technology. The component includes a composite slab body 1, a base plate 2, and supporting adjustment and jacking structures, which are used to achieve precise positioning of the composite slab body 1 and adjustment of its horizontal and vertical states.

[0030] Reference Figure 3 The bottom of the composite plate body 1 is provided with multiple conical grooves 4, and the inner wall of the top of the conical grooves 4 is provided with guide holes 5. Multiple first vertical rods 3 are fixed to the top of the base plate 2, the number and position of the first vertical rods 3 corresponding to the conical grooves 4. When the composite plate body 1 is hoisted onto the base plate 2, the first vertical rods 3 are first inserted into the conical grooves 4 to provide initial positioning guidance for the composite plate body 1. As the composite plate body 1 continues to move downwards, the first vertical rods 3 are further inserted into the guide holes 5 to achieve initial positioning of the composite plate body 1.

[0031] Reference Figure 4To ensure the horizontal position of the composite plate body 1 after it is placed on the base plate 2, two sets of adjustment structures are provided between the composite plate body 1 and the base plate 2. Each set of adjustment structures includes two base plates 7 fixed to the top of the base plate 2, and a screw 8 is rotatably connected between the two base plates 7. A trapezoidal top block 10 is threaded onto the outer wall of the screw 8, and the trapezoidal top block 10 slides on the top of the base plate 2. One end of the screw 8 rotates through one of the base plates 7 and extends to one side of the base plate 7, and one end of the screw 8 has a hexagonal groove 9. A sloped groove 6 is provided on one side of the bottom of the composite plate body 1, and the sloped surface of the trapezoidal top block 10 engages with the sloped surface of the sloped groove 6. When the composite plate body 1 tilts, the screw 8 is driven to rotate by a hexagonal wrench engaging with the hexagonal groove 9, controlling the movement of the trapezoidal top block 10. The trapezoidal top block 10 engages with the sloped surface of the sloped groove 6, lifting the composite plate body 1, thereby adjusting the horizontal position of the composite plate body 1.

[0032] Reference Figure 2 , Figure 5 and Figure 6 In addition, a T-shaped plate 11 is provided on one side of the base plate 2, and a rotating arm 26 is rotatably connected to one side of the T-shaped plate 11. A second vertical rod 27 is fixed to the top of the rotating arm 26, and a fixed plate 28 is fixedly sleeved on the outer wall of the second vertical rod 27. A pressure plate 30 located below the fixed plate 28 is slidably sleeved on the outer wall of the second vertical rod 27, and a protruding rod is fixed to one side of the pressure plate 30. A first spring 29 is fixed between the top of the pressure plate 30 and the top of the fixed plate 28 through a spring seat. The spring constant of the first spring 29 is in the range of 50 N / m to 100 N / m. The first spring 29 pushes the protruding rod on one side of the pressure plate 30 to abut the top of the composite plate body 1. An infrared sensor 31 that cooperates with the pressure plate 30 is fixed to the top of the T-shaped plate 11 to determine the distance between the T-shaped plate 11 and the pressure plate 30, thereby determining whether the composite plate body 1 is tilted.

[0033] Specifically, during the adjustment process, the rotating arm 26 is first rotated to make it fit against the composite plate body 1. After the rotating arm 26 rotates, it pushes the pressure plate 30 upward. When the pressure plate 30 moves above the composite plate body 1, the pushing force on it is released. The first spring 29 pushes the pressure plate 30 downward, so that the protrusion on one side abuts against the top of the composite plate body 1. The infrared sensor 31 detects the distance of the pressure plate 30, and based on the distance detection of the corresponding pressure plates 30 by multiple infrared sensors 31, it is determined whether the composite plate body 1 is tilted. When tilted, the screw 8 is driven to rotate by the hexagonal wrench, controlling the movement of the trapezoidal top block 10 to adjust the horizontal state of the composite plate body 1.

[0034] Reference Figure 2 , Figure 7 and Figure 12To ensure the verticality of the composite plate body 1, multiple pushing structures are provided on the side of the base plate 2 away from the T-shaped plate 11. Each pushing structure includes a first fixed seat 16 located on one side of the base plate 2, a rotating cylinder 22 rotating on the top and one side of the first fixed seat 16, and a rotating threaded rod 17. A threaded hole 18 is provided on the side of the base plate 2 away from the T-shaped plate 11, and the threaded hole 18 is threadedly connected to the rotating threaded rod 17 to fix the base plate 2 to the first fixed seat 16. A lead screw 23 is slidably connected inside the rotating cylinder 22, and a nut block 24 threadedly connected to the lead screw 23 is rotatably connected to the top of the rotating cylinder 22. A second fixed seat 25 is rotatably connected to the top of the lead screw 23, and the second fixed seat 25 is fixedly connected to one side of the composite plate body 1 by screws to push the composite plate body 1.

[0035] Reference Figure 5 , Figure 7 and Figure 12 A plug plate 12 is fixed to the side of the T-shaped plate 11 near the base plate 2. The side of the base plate 2 near the T-shaped plate 11 has a slot 13 that engages with the plug plate 12 for positioning the T-shaped plate 11. Multiple first bolts 14 rotatably pass through the T-shaped plate 11 and are threaded to the base plate 2 for fixing the base plate 2 and the T-shaped plate 11 together. Multiple pressure sensors 15 are fixedly embedded on the side of the T-shaped plate 11 near the composite plate body 1 for detecting the compressive force on the pressure sensors 15 when the second fixing seat 25 pushes against the composite plate body 1.

[0036] During the jacking process, the insert plate 12 is first inserted into the slot 13, and the T-shaped plate 11 is fixed to the base plate 2 using the first bolt 14. Then, the second fixing seat 25 is fixedly connected to the composite plate body 1 using screws. Next, the screw rod 23 is extended by rotating the nut block 24, so that the second fixing seat 25 is tightly fitted to the composite plate body 1. At this time, multiple pressure sensors 15 on one side of the T-shaped plate 11 can detect the pressure applied by the composite plate body 1 to the T-shaped plate 11 in real time. Based on the detection data of the multiple pressure sensors 15 on the multiple T-shaped plates 11, it is determined whether the composite plate body 1 is in a vertical state. If a deviation occurs, the extension length of the corresponding screw rod 23 can be finely adjusted to complete the adjustment of the vertical state of the composite plate body 1.

[0037] Reference Figure 2 , Figure 7 and Figure 12A rotating ring 20 is rotatably fitted onto the outer wall of the rotating threaded rod 17, and a bending guide plate 19 is fitted onto the outer wall of the rotating threaded rod 17, with the bending guide plate 19 located between the rotating ring 20 and the base plate 2. Multiple fixing rods 21 are fixed to the side of the rotating ring 20 near the base plate 2, with one end of each fixing rod 21 extending into the bending guide plate 19 to position it. When the rotating threaded rod 17 is connected through the threaded hole 18, the bending guide plate 19 can be clamped by the cooperation between the rotating ring 20 and the base plate 2.

[0038] When the composite slab body 1 is hoisted onto the base plate 2, the T-shaped plate 11 is inserted into the slot 13 via the insert plate 12, and the T-shaped plate 11 is fixed to the base plate 2 by the first bolt 14. Then, the bending guide plate 19 is fitted onto the rotating threaded rod 17, and the connection between the base plate 2 and the first fixed seat 16 is completed by the engagement of the rotating threaded rod 17 with the threaded hole 18. The bending guide plate 19 is clamped and fixed by the action of the base plate 2 and the rotating ring 20. When the composite slab body 1 is hoisted onto the base plate 2 by the tower crane, the T-shaped plate 11 limits the position of the composite slab body 1, while the bending guide plate 19 guides the composite slab body 1, avoiding large errors during the hoisting process.

[0039] Reference Figure 1 , Figure 7 and Figure 12 Pressure plates 47 are fixed to both the top and bottom of the second fixing seat 25 to ensure the uniformity of force on the composite plate body 1 when the second fixing seat 25 is pushed. The pressure plates 47 can increase the contact area between the second fixing seat 25 and the composite plate body 1, thereby reducing local stress concentration and improving the stress stability of the composite plate body 1.

[0040] Reference Figure 8 and Figure 9 The prefabricated building composite slab construction equipment includes a composite slab positioning component as described above, and also includes a U-shaped base 34 and a connecting column 36. The top of the U-shaped base 34 and the bottom of the connecting column 36 are fixedly connected by steel wire ropes 35. The top of the connecting column 36 is connected to the ropes of a tower crane for overall hoisting of the construction equipment. A horizontal plate 37 is slidably connected inside the U-shaped base 34, and a hoisting structure is provided between the horizontal plate 37 and the top of the composite slab body 1.

[0041] Reference Figure 9 and Figure 10The hoisting structure includes multiple V-shaped rods 32 fixed to the top of the composite plate body 1, with a single horizontal bar 33 passing through each V-shaped rod 32. The bottom of the horizontal plate 37 has multiple moving slots 39, each containing two guide rods 40. Two moving seats 41 are slidably fitted onto the outer walls of the two guide rods 40, and two second springs 42 are fitted onto the outer walls of each guide rod 40. The stiffness coefficient of the second springs 42 ranges from 30 N / m to 80 N / m. The ends of the two second springs 42 that are close to each other abut against one side of the corresponding moving seat 41 via spring seats, while the ends that are far apart abut against one inner wall of the moving slot 39 via spring seats, driving the two moving seats 41 to move towards the center.

[0042] Reference Figure 10 and Figure 11 The bottom of each of the two movable seats 41 is fixed with a first hook 44 and a second hook 45, respectively, and the first hook 44 and the second hook 45 are staggered. The first hook 44 and the second hook 45 are used to lift the crossbar 33. An electromagnet 43 is fixed on the side of each movable seat 41 that is close to each other. When the two electromagnets 43 are energized, they generate a repulsive force, which is greater than the elastic force of the second spring 42. This repulsive force is used to drive the two movable seats 41 to move to both sides, thereby releasing the lifting of the crossbar 33 by the first hook 44 and the second hook 45.

[0043] During the hoisting process, the tower crane moves the horizontal plate 37 above the composite slab body 1. The horizontal plate 37 moves downwards, with the top of the triangular bar 46 positioned between the first hook 44 and the second hook 45. As the horizontal plate 37 moves downwards, the triangular bar 46 pushes the first hook 44 and the second hook 45 to move to both sides until they are below the horizontal bar 33. At this point, under the thrust of the second spring 42, the two moving seats 41 move towards the center, and the first hook 44 and the second hook 45 hook onto the horizontal bar 33. The tower crane is then able to hoist the composite slab body 1 to the designated position.

[0044] When it is necessary to release the first hook 44 and the second hook 45 from the horizontal bar 33, the horizontal plate 37 moves the first hook 44 and the second hook 45 downwards until the hook parts of the first hook 44 and the second hook 45 are below the horizontal bar 33. Then, after the electromagnet 43 is energized, the repulsive force between the two electromagnets 43 pushes the moving seat 41 to move outwards, releasing the first hook 44 and the second hook 45 from the horizontal bar 33. The entire process requires no manual operation, greatly improving the hoisting and assembly efficiency of the composite plate body 1.

[0045] Reference Figure 9A first threaded rod 38 is rotatably connected to the top of the horizontal plate 37 via a base, and one end of the first threaded rod 38 is threaded through the U-shaped seat 34. The first threaded rod 38 cooperates with the U-shaped seat 34 to adjust the relative distance between the horizontal plate 37 and the U-shaped seat 34, thereby fine-tuning the position of the hoisted composite plate body 1. By rotating the first threaded rod 38, the movement distance of the horizontal plate 37 can be precisely controlled, improving the positioning accuracy of the hoisting of the composite plate body 1.

[0046] In another embodiment: Reference Figure 10 and Figure 11 An improvement upon Embodiment 1 is made by fixing a triangular strip 46 to the top of the crossbar 33 to guide the first hook 44 and the second hook 45 to both sides. During the downward movement of the crossbar 37, the triangular strip 46 first contacts the first hook 44 and the second hook 45, pushing them to move to both sides. As the crossbar 37 continues to move downward, the first hook 44 and the second hook 45 move below the crossbar 33 and, under the thrust of the second spring 42, move towards the center, hooking the crossbar 33. The triangular strip 46 simplifies the lifting process and improves lifting efficiency.

[0047] The method of using prefabricated building composite slab construction equipment includes the following steps: S1. The horizontal plate 37 is moved above the composite plate body 1 by the tower crane. The horizontal bar 33 is located between the adjacent first hook 44 and second hook 45. Then the horizontal plate 37 is moved down. The top of the triangular bar 46 is located between the first hook 44 and second hook 45. As the horizontal plate 37 moves down, the triangular bar 46 pushes the first hook 44 and second hook 45 to move to both sides until the first hook 44 and second hook 45 move down to the bottom of the horizontal bar 33 and move towards the middle under the push of the second spring 42. At this time, the first hook 44 and second hook 45 can hook the horizontal bar 33, and the tower crane can lift the composite plate body 1 to the designated position. S2. When the composite plate body 1 is hoisted above the base plate 2, the first threaded rod 38 is driven to rotate by the motor. The first threaded rod 38 and the horizontal plate 37 are displaced relative to each other, and the position of the composite plate body 1 is finely adjusted so that the guide hole 5 is aligned with the first vertical rod 3. Then the composite plate body 1 is lowered to the top of the base plate 2. The first vertical rod 3 extends into the conical groove 4 first. The inner wall of the conical groove 4 guides the first vertical rod 3 until the first vertical rod 3 is inserted into the guide hole 5, and the positioning of the composite plate body 1 is initially completed. S3. When the composite plate body 1 is hoisted onto the base plate 2, the T-shaped plate 11 is inserted into the slot 13 through the insert plate 12, and the T-shaped plate 11 is fixed to the base plate 2 by the first bolt 14. Then, the bending guide plate 19 is sleeved on the rotating threaded rod 17, and the connection between the base plate 2 and the first fixed seat 16 is completed by the cooperation of the rotating threaded rod 17 and the threaded hole 18. The bending guide plate 19 is clamped and fixed by the base plate 2 and the rotating ring 20. When the composite plate body 1 is hoisted onto the base plate 2 by the tower crane, the T-shaped plate 11 limits the composite plate body 1, and the bending guide plate 19 can guide the composite plate body 1 to avoid large errors during the hoisting process of the composite plate body 1. S4. Rotate the rotating arm 26 to make the rotating arm 26 fit against the composite plate body 1. After the rotating arm 26 rotates, it pushes the pressure plate 30 to move upward. When the pressure plate 30 moves above the composite plate body 1, the pushing force on it is released. The first spring 29 pushes the pressure plate 30 downward and makes the protrusion on one side abut against the top of the composite plate body 1. The infrared sensor 31 detects the distance of the pressure plate 30. Based on the distance detection of the corresponding pressure plate 30 by multiple infrared sensors 31, it is determined whether the composite plate body 1 is tilted. When tilted, the screw 8 is driven to rotate by the hexagonal wrench and the hexagonal groove 9 to control the movement of the trapezoidal top block 10. The trapezoidal top block 10 and the inclined surface of the inclined groove 6 are used to lift the composite plate body 1, thereby ensuring that the top of the composite plate body 1 is in a horizontal state. S5. Next, the second fixing seat 25 is fixedly connected to the composite plate body 1 by screws. The rotation of the nut block 24 drives the lead screw 23 to extend, and the second fixing seat 25 cooperates with the pressure plate 47 to push the composite plate body 1 until the composite plate body 1 is tightly attached to the T-shaped plate 11. Multiple pressure sensors 15 on one side of the T-shaped plate 11 can detect the pressure applied by the composite plate body 1 to the T-shaped plate 11 in real time. Based on the multiple pressure sensors 15 on the multiple T-shaped plates 11, it can detect whether the composite plate body 1 is in a vertical state. According to the vertical requirements, the extension length of the corresponding lead screw 23 is finely adjusted to complete the adjustment of the vertical state of the composite plate body 1.
