Description

Technical Field

[0001] The invention relates to the technical field of building hoisting equipment, in particular to a tower crane hoist suitable for lightweight partition boards and a hoisting method thereof. Background Art

[0002] In the field of prefabricated buildings, the lifting operations of lightweight partition panels currently generally rely on tower cranes and are operated using traditional mechanical hoists. Most of these hoists are rigid clamping structures, such as wire rope binding, bolt clips, or simple clamps. However, this clamping method has obvious limitations. Due to the uneven distribution of clamping force, it is easy to cause pressure damage to the surface of the wall panel and even cause cracks in the internal structure, affecting the overall performance and construction quality of the wall. In addition, in the actual assembly process, a vertical installation method is usually adopted. However, due to the relatively large dead weight of lightweight partition panels, workers lack an effective fulcrum for their hands during transportation and positioning, resulting in inconvenient operation and high labor intensity. At the same time, the vertical assembly method is not conducive to the continuous lifting and efficient installation of multiple wall panels. The overall construction efficiency is low, and the convenience and safety of assembly still need to be improved. For this reason, a tower crane hoist suitable for lightweight partition panels and a lifting method thereof are proposed. Summary of the Invention

[0003] The object of the present invention is to provide a tower crane hoist suitable for lightweight partition panels and a hoisting method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a tower crane sling suitable for lightweight partition panels, comprising:

[0005] Fixed beam;

[0006] A clamping substrate is arranged on the fixed beam;

[0007] The clamping wing plate is connected to the fixed beam through the adjustment mechanism;

[0008] And a central controller connected to the adjustment mechanism is used to adjust the opening angle between the clamping wing plate and the clamping base plate by driving the adjustment mechanism; during the assembly of the lightweight partition board, when the lightweight partition board is completed and assembled with the clamping base plate, the central controller drives the clamping wing plate to rotate tilted toward the direction of the clamping base plate by controlling the adjustment mechanism, so that the angle between the two gradually decreases.

[0009] As a further solution of the present invention: two hydraulic cylinders are installed at the ends of the clamping base and the clamping wing away from the fixed beam, wherein the two hydraulic cylinders connected to the clamping base are one group, and the two hydraulic cylinders connected to the clamping wing are another group, and the ends of the two groups of hydraulic cylinders away from the clamping base and / or the clamping wing are both provided with a flipping mechanism.

[0010] As a further solution of the present invention: the flipping mechanism includes a load-bearing beam, and two bearing seats are installed on the end face of the load-bearing beam adjacent to the hydraulic cylinder. A transmission shaft is provided between the two bearing seats, and the ends of the transmission shaft respectively pass through the two bearing seats. The two ends of the transmission shaft are rotationally connected to the ends of the two hydraulic cylinders, and one end of the transmission shaft is installed with a gear box connected to the hydraulic cylinder.

[0011] As a further solution of the present invention: the adjustment mechanism includes a coupling and a control motor arranged on the fixed beam, the output end of the control motor is connected to the coupling, and the two non-adjacent sides of the coupling are installed with linkage shafts arranged parallel to the fixed beam, and the ends of the two linkage shafts away from the coupling are installed with rotating shaft supports connected to the end face of the fixed beam.

[0012] As a further solution of the present invention: the clamping wing plate includes two movable steel plates, the two movable steel plates are respectively connected to two linkage shafts, and a second reinforcing steel bar is arranged between the two movable steel plates, and a pressure sensing structure is installed on the end face of the second reinforcing steel bar adjacent to the clamping base plate.

[0013] As a further solution of the present invention: the pressure sensing structure includes a positioning reinforcement rib and several telescopic units connecting the positioning reinforcement rib and the second reinforcement steel bar, several pressure sensing arrays are provided on the end surface of the positioning reinforcement rib away from the telescopic unit, and a control unit is installed on the second reinforcement steel bar for controlling the distance between the positioning reinforcement rib and the second reinforcement steel bar.

[0014] As a further solution of the present invention: the central controller establishes a two-way data connection with the control motor, gear box, control unit and hydraulic cylinder respectively through the Bluetooth communication protocol.

[0015] As a further solution of the present invention: the end surface of the fixed beam provided with a clamping base plate is also equipped with a supporting steel beam.

[0016] As a further solution of the present invention: the clamping base plate includes two fixed steel plates perpendicular to the end surface of the fixed beam and a first reinforcing steel bar connected to the two fixed steel plates.

[0017] A method for hoisting a lightweight partition wall panel using a tower crane hoist comprises the following steps:

[0018] S1. Expand the clamping wing to its maximum opening and extend the hydraulic cylinder to its maximum stroke, while keeping the load beam in the horizontal loading position;

[0019] S2. Place the lightweight partition board steadily on the clamping base plate, and control the motor through the central controller to slowly close the clamping wing plate until the pressure sensing structure on the clamping wing plate contacts the side of the lightweight partition board;

[0020] S3. When the clamping wing plate gradually approaches a horizontal state, the control unit controls the telescopic unit to extend radially until the feedback value of the pressure sensor array reaches the preset clamping threshold; at the same time, the hydraulic cylinder is adjusted to drive the load-bearing beam to gradually retract until the lower part of the lightweight partition board contacts the load-bearing plate and the force is stable;

[0021] S4. Lift the hoist to the predetermined position. The central controller monitors the pressure distribution of the positioning reinforcement ribs in real time to ensure the stability of the lightweight partition panels during the lifting process. After the panels are in place, they are stabilized using external supports or temporary fixing devices.

[0022] S5. After the lightweight partition board is fixed, the central controller sends a flip command to drive the servo motor in the gearbox to rotate the transmission shaft, so that the load-bearing beam and the bearing seat connected to the transmission shaft flip to the set angle. At this time, the lightweight partition board is separated from the load-bearing beam and released. Subsequently, the hoisting device withdraws from the construction area, completing an operation cycle.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] This application realizes the coordinated cooperation between the clamping base plate, the central controller, the adjustment mechanism and the clamping wing plate, so that the hoist is operated in a horizontal state when assembling lightweight partition boards, thereby simplifying the assembly process and improving assembly efficiency. At the same time, the clamping wing plate works in coordination with the pressure sensing array to achieve adaptive dynamic adjustment of the clamping force, effectively avoiding surface pressure loss and internal structure cracking of the lightweight partition boards due to stress concentration, and significantly improving the safety and reliability of the lifting operation.

[0025] This application uses a wireless collaborative mechanism between the central controller and the control motor, gearbox, control unit, and hydraulic cylinder to ensure high-precision synchronization of clamping and flipping actions, improve the accuracy and stability of the installation and positioning of lightweight partition panels, and effectively avoid the hidden dangers of offset and falling during high-altitude unloading of panels; at the same time, modular design and intelligent control processes greatly reduce manual intervention links, adapt to the industrial needs of rapid installation of wall panels in prefabricated buildings, and significantly improve overall construction efficiency compared to traditional methods.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1-7 In an embodiment of the present invention, a tower crane hoist suitable for lightweight partition panels includes:

[0036] Fixed beam 1;

[0037] A clamping substrate is provided on the fixed beam 1;

[0038] The clamping wing plate is connected to the fixed beam 1 through the adjustment mechanism;

[0039] And a central controller 16 connected to the adjustment mechanism is used to adjust the opening angle between the clamping wing and the clamping base plate by driving the adjustment mechanism; during the assembly of the lightweight partition board, when the lightweight partition board is completed and assembled with the clamping base plate, the central controller 16 drives the clamping wing to rotate tilted toward the direction of the clamping base plate by controlling the adjustment mechanism, so that the angle between the two gradually decreases.

[0040] Specifically, the fixed beam 1 is a rectangular hollow steel tube. Two lifting ears 101 are installed on the end face of the fixed beam 1 away from the clamping substrate, and the two lifting ears 101 are respectively located on both sides of the fixed beam 1, which are used to connect with the hook of the tower crane to ensure that the tower crane will not tilt to one side when lifting the lightweight partition board. The fixed beam 1 is provided with a clamping substrate and a supporting steel beam 2 is also installed on the end face. The supporting steel beam 2 is provided with an extension portion extending from the end face of the clamping substrate. The extension portion and the end face of the supporting steel beam 2 together form an L-shaped structure. The interior of the L-shaped structure is used to fix the upper part of the lightweight partition board, so that the lightweight partition board can be well stabilized during the initial assembly process, and an elastic pad is provided on the inner side of the L-shaped structure, which can effectively protect the upper part of the lightweight partition board, offset the impact force generated during crimping, and prevent the top surface of the lightweight partition board from being crushed and cracked.

[0041] The clamping base plate and the fixed beam 1 are fixedly connected, and the clamping base plate and the L-shaped structure are combined to form an area for placing the partition board. One side of the lightweight partition board is fixed through this area to facilitate the assembly of the lightweight partition board in a horizontal manner. At this time, one side of the L-shaped structure can be used as a horizontal plane to support the lightweight partition board, and then complete the subsequent assembly. The efficiency of horizontal assembly of lightweight partition boards is higher than that of vertical assembly of lightweight partition boards.

[0042] The ends of the clamping wing plates are connected to the fixed beam 1 through an adjusting mechanism. Before assembling the lightweight partition board, the central controller 16 can drive the adjusting mechanism to adjust the opening angle of the clamping wing plates so that they are opened relative to the clamping base plate, making it convenient for the staff to place the lightweight partition board on the static clamping working surface of the clamping base plate. Subsequently, the angle between the clamping wing plates and the clamping base plate is reduced again through the adjusting mechanism so that the two are brought closer together, thereby achieving the clamping and fixation of the lightweight partition board.

[0043] Through the above technical scheme, compared with the traditional vertical assembly method, the present application can adopt a horizontal state to assemble lightweight partition boards, thereby improving assembly efficiency and having better operational convenience and assembly stability: the specific operation of assembling lightweight partition boards in the horizontal state is to first lay the sling flat, and then drive the adjustment mechanism through the central controller 16 to adjust the opening angle between the clamping wing plate and the clamping base plate, so that a larger lightweight partition board placement space is formed between it and the clamping base plate, which is convenient for the staff to lift and place the lightweight partition board smoothly into the sling; when the lightweight partition board is assembled, the angle between the clamping wing plate and the clamping base plate is reduced by the adjustment mechanism, so that the two are close together and clamp the lightweight partition board to achieve firm fixation. Subsequently, the entire sling can be lifted together with the lightweight partition board by a tower crane to complete the lifting operation. Compared with the traditional vertical assembly method of the sling, the horizontal assembly operation is simpler, which not only improves the assembly efficiency, but also enhances the safety and stability of the operation.

[0044] See also Figure 4 In one embodiment, in this embodiment, preferably, two hydraulic cylinders 3 are installed at the ends of the clamping base and the clamping wing away from the fixed beam 1, wherein the two hydraulic cylinders 3 connected to the clamping base are one group, and the two hydraulic cylinders 3 connected to the clamping wing are another group, and the ends of the two groups of hydraulic cylinders 3 away from the clamping base and / or the clamping wing are provided with a flipping mechanism, and the distance between the clamping base and the flipping mechanism and / or the clamping wing and the flipping mechanism can be adjusted respectively by the two groups of hydraulic cylinders 3, thereby realizing the clamping requirements of lightweight partition boards of different heights, so that the sling can be suitable for lifting operations of lightweight partition boards of various specifications, thereby improving the versatility and flexibility of use of the equipment.

[0045] See also Figure 4 In one embodiment, in this embodiment, preferably, the flipping mechanism includes a load-bearing beam 4, and two bearing seats 5 are installed on the end surface of the load-bearing beam 4 adjacent to the hydraulic cylinder 3. A transmission shaft 6 is provided between the two bearing seats 5, and the ends thereof respectively pass through the two bearing seats 5. The two ends of the transmission shaft 6 are rotationally connected to the ends of the two hydraulic cylinders 3, and one end of the transmission shaft 6 is installed with a gear box 7 connected to the hydraulic cylinder 3.

[0046] Specifically, an installation groove for placing lightweight partition boards is formed between the two supporting beams 4 of the two flipping mechanisms. The supporting beam 4 includes an L-shaped plate 401 and a supporting plate 402. A stiffening plate 403 is arranged between the L-shaped plate 401 and the supporting plate 402 to enhance the stability between the L-shaped plate 401 and the supporting plate 402. The supporting plate 402 is arranged on the end face of the L-shaped plate 401 away from the hydraulic cylinder 3. The supporting plate 402 contacts the bottom of the lightweight partition board to provide support. Two symmetrically arranged bearing seats 5 are installed on the end face of the L-shaped plate 401 away from the supporting plate 402. A transmission shaft 6 is arranged between the two bearing seats 5. Both ends of the transmission shaft 6 pass through the bearing seats 5 respectively and are fixedly connected thereto. Both ends of the transmission shaft 6 are rotationally connected to the telescopic ends of the two hydraulic cylinders 3, wherein a gear box 7 is connected to the end of the hydraulic cylinder 3, and the output end of the gear box 7 is connected to the transmission shaft 6. An angle feedback system and a servo motor are respectively provided in the gear box 7, and the angle feedback system The servo motor is connected to the central controller 16. The angle feedback system monitors the flipping angle of the load-bearing beam 4 and converts its flipping angle into a flipping angle signal and feeds it back to the central controller 16, which controls the clockwise or counterclockwise rotation of the servo motor to achieve closed-loop control (the angle feedback system is a prior art and will not be described in detail here). The servo motor is fixedly connected to the end of the transmission shaft 6. When the servo motor in the gear box 7 is turned on, it drives the transmission shaft 6 to rotate, and the transmission shaft 6 drives the bearing seat 5 fixed to it to rotate synchronously. At this time, the bearing seat 5 can drive the load-bearing beam 4 to complete a 0-90° flip, which facilitates the L-shaped plate 401 to gradually extend outward during the flipping process, and generate an inclination angle with the contact surface of the lightweight partition board. The synergistic effect of gravity and mechanical separation is used to make the lightweight partition board smoothly separate from the sling, completing the damage-free unloading of the board. The various components ensure that the flipping action is synchronized, accurate and impact-free through the collaborative mechanism of power transmission, angle control and structural limitation, which is adapted to the needs of diverse construction scenarios.

[0048] Specifically, the coupling 10 and the control motor are both fixedly mounted in the middle area of the end face of the fixed beam 1. The two linkage shafts 11 on the coupling 10 are driven by the control motor to rotate in the same direction and speed. The shaft support 12 includes a fixed part 1201 and a rotating part 1202, wherein the fixed part 1201 is fixedly connected to the fixed beam 1, and the fixed part 1201 and the rotating part 1202 are rotatably connected. The rotating part 1202 is fixedly connected to the upper part of the clamping wing plate, and the rotating part 1202 is fixedly connected to the end of the linkage shaft 11. During the rotation of the linkage shaft 11, the rotating part 1202 is driven to rotate synchronously, and the rotating part 1202 drives the clamping wing plate to adjust the inclination angle. In addition, the two fixed parts 1201 are used to limit the displacement of the end of the linkage shaft 11, and the two rotating parts 1202 provide support for the two ends of the linkage shaft 11 to ensure its stability during rotation and avoid an unbalanced state caused by uneven force.

Furthermore, the two movable steel plates 13 are respectively fixedly connected to the two rotating parts 1202 to ensure that the linkage shaft 11 can drive the movable steel plates 13 to rotate synchronously while rotating, realize angle opening and closing, form a dynamic clamping working surface, and sense the clamping force of the clamping wing plate on the lightweight partition board through the pressure sensing structure 15 to ensure that the lightweight partition board will not fall off during the lifting process.

[0050] See also Figure 4 In one embodiment, in this embodiment, preferably, the pressure sensing structure 15 includes a positioning reinforcement rib 1501 and a plurality of telescopic units 1502 connecting the positioning reinforcement rib 1501 and the second reinforcement steel bar 14. The thickness tolerance of the wall panel is compensated by adjusting the telescopic amount to ensure that the clamping surface fits without gaps. A plurality of pressure sensing arrays 1503 are provided on the end surface of the positioning reinforcement rib 1501 away from the telescopic unit 1502. A control unit 1504 is installed on the second reinforcement steel bar 14 for controlling the distance between the positioning reinforcement rib 1501 and the second reinforcement steel bar 14. The pressure sensing array 1503 monitors the distribution of contact pressure with the lightweight partition board in real time, and transmits the data to the control unit 1504 to form a closed-loop feedback, dynamically adjusts the action of the telescopic unit 1502, so that the clamping force is balanced and stable at the set threshold, and realizes the coordinated operation of adaptive clamping and precise loss prevention control.

[0051] See also Figure 4In one embodiment, in this embodiment, preferably, the central controller 16 establishes a two-way data connection with the control motor, the gear box 7, the control unit 1504, and the hydraulic cylinder 3 respectively through the Bluetooth communication protocol.

Furthermore, the fixed steel plates 8 are rectangular, the tops of the fixed steel plates 8 are rigidly connected to the fixed beam 1, and the first reinforcing steel bar 9 runs through the two fixed steel plates 8 horizontally, significantly improving the structural bending stiffness and suppressing local deformation; the two fixed steel plates 8 and the first reinforcing steel bar 9 together form a static clamping working surface, providing a stable support reference surface for the lightweight partition board, and its rigid connection characteristics ensure that there is no displacement during the clamping process, realizing the integrated integration of the pre-positioning of the lightweight partition board and the basic bearing function.

[0053] A method for hoisting a lightweight partition wall panel using a tower crane hoist comprises the following steps:

[0054] S1. Expand the clamping wing to its maximum opening, extend the hydraulic cylinder 3 to its maximum stroke, and keep the load beam 4 in a horizontal loading position;

[0056] S3. When the clamping wing plate gradually approaches a horizontal state, the control unit 1504 controls the telescopic unit 1502 to extend radially until the feedback value of the pressure sensing array 1503 reaches the preset clamping threshold; at the same time, the hydraulic cylinder 3 is adjusted to drive the load-bearing beam 4 to gradually retract until the lower part of the lightweight partition board contacts the load-bearing plate 402 and the force is stable;
