Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a heavy-duty structure lifting synchronous cable wind device. Background Technology

[0002] With the development of the construction industry, prefabricated building components are increasingly being used in high-rise and super high-rise buildings to improve construction efficiency and quality control. However, prefabricated building components are characterized by their large size and heavy weight. When hoisting such heavy components, if the installation height is high, the heavy components will sway violently under the influence of strong winds or vibrations, affecting the construction process. Guy ropes are a crucial element in controlling the swaying of heavy components during construction, but the raising and lowering of guy ropes during high-altitude hoisting is difficult and cannot be done manually. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a synchronous cable wind device for lifting heavy structures, which improves the stability of hoisting by simultaneously lifting the cable wind device during the lifting process of heavy structures.

[0004] The objective of this invention can be achieved through the following technical solutions.

[0005] This invention provides a heavy-duty structure lifting synchronous cable-stayed device, comprising left and right building columns, a heavy-duty structure in the middle, cable-stayed ropes, steel guide cables, steel hoops, movable hooks, upper guide ropes, a first lower guide rope, and a second lower guide rope. Each of the left and right building columns consists of two vertical columns arranged one behind the other and a top plate above the vertical columns, forming a U-shape. Two horizontal crossbars extending from the top of the top plate to the middle of the two building columns are provided on the top plates of both the left and right building columns. The horizontal crossbars on the left and right building columns are symmetrically arranged. A fixed pulley is provided at one end of the horizontal crossbar near the middle of the two building columns, and a large winch is provided at the other end. The steel cable of the large winch passes around the fixed pulley, and a hook for lifting the heavy-duty structure is provided at the bottom end of the steel cable. The heavy-duty structure is fixed at all four corners. A third small winch is installed. Each vertical column has a vertical steel guide cable on the side closest to the heavy structure. The top of the steel guide cable is fixedly connected to the top of the roof plate, and the bottom is fixedly connected to the ground. The steel guide cable and the vertical column are parallel to each other in the vertical direction. Multiple steel hoops are successively fitted over the vertical column and the steel guide cable from top to bottom. Each steel guide cable is fitted with a movable hook that can move up and down along the steel guide cable. The movable hook has an opening that can be opened and closed on the side facing the steel guide cable. The lower end of the upper guide rope that allows the movable hook to move up and down is connected to the movable hook. The upper ends of the first lower guide rope and the second lower guide rope that allow the movable hook to move left, right and forward and backward are respectively connected to the movable hook. One end of the guy rope is connected to the third small winch, and the other end is connected to the movable hook.

[0006] Furthermore, the movable hook includes a first rigid block, a second rigid block, and a third rigid block. The first rigid block has a U-shaped structure with its opening facing the steel guide cable. The length of the upper rod of the first rigid block is greater than the length of the lower rod. A through hole is provided at the left end of the upper rod. The first rigid block, the second rigid block, and the third rigid block are connected in sequence. One end of the second rigid block is connected to the left end of the lower rod of the first rigid block through a first elastic hinge. The first elastic hinge causes the second rigid block to open outward relative to the lower rod of the first rigid block. One end of the third rigid block is connected to the other end of the second rigid block through a second elastic hinge. The second elastic hinge causes the third rigid block to open outward relative to the second rigid block. A long strip-shaped permanent magnet is fixedly installed at the other end of the third rigid block. The permanent magnet passes through the through hole on the upper rod and is located above the upper rod. The long strip-shaped permanent magnet and the third rigid block form a "┏" shape. An electric controller, an electromagnet, and a wire are installed at the right end above the upper rod. The electric controller is electrically connected to the electromagnet through the wire to control the activation or deactivation of the electromagnet's magnetism.

[0007] Furthermore, a first reflective film is provided on the steel hoop, and a second reflective film is provided on both the upper and lower rods.

[0008] Furthermore, the device also includes a first small winch, with the upper end of the upper guide rope connected to the first small winch.

[0009] Furthermore, the device also includes a first controller, a third controller, and a microcomputer. The first controller is connected to a first small winch via signal control, the third controller is connected to a large winch via signal control, and the microcomputer is connected to a third small winch via signal control.

[0010] Furthermore, the device also includes a lidar that scans the first reflective film and the second reflective film.

[0011] The beneficial effects of this invention are as follows: 1. Due to the constraint of the steel hoop on the steel guide cable, the heavy component is stably operated by the constraint of the movable hook and guy rope fitted on the steel guide cable; 2. Through the opening and closing of the movable hook and the control of the movable hook in three degrees of freedom by the upper guide rope, the first lower guide rope, and the second lower guide rope during the opening and closing process, the movable hook can rise over the steel hoop after opening and then close again to lock the steel guide cable into the U-shaped opening, so that the heavy component can also operate stably during the rising process of the movable hook over the steel hoop; 3. This invention uses multiple controllers to control the winch, so that the hoisting process is fully automated and intelligently controlled by the winch system, improving construction efficiency, greatly optimizing the economy of the construction process and avoiding construction dangers, avoiding repeated untying of the guy rope during the hoisting of heavy components, greatly improving work efficiency, and effectively reducing the construction risk factor.

[0019] like Figure 1-6As shown, a heavy-duty structure lifting synchronous cable wind device includes building columns 2 located on the left and right sides. Each building column 2 consists of two vertical columns arranged one in front of the other and a top plate located above the vertical columns, forming a U-shape. Two horizontal crossbars extending from the top of the top plate of each of the left and right building columns 2 towards the middle of the two building columns 2 are provided, and the horizontal crossbars on the left and right building columns 2 are symmetrically arranged. A fixed pulley is provided at one end of the horizontal crossbar near the middle of the two building columns 2, and a large winch 3 is provided at the other end. The steel cable 5 of the large winch 3 passes around the fixed pulley, and a hook 8 for lifting the heavy structure 1 is provided at the bottom end of the steel cable 5. In this embodiment, the heavy structure 1 is lifted by four hooks. A first small winch 6, a first controller 7, a first control line 12, a WiFi 13, and a third controller 39 are also respectively provided on the top of the left and right building columns 2. The first controller 7 and the third controller 39 are respectively connected to the WiFi 13 signal. The first controller 7 is connected to the first small winch 6 via the first control line 12 to control the operation of the first small winch 6; the third controller 39 is connected to the large winch 3 via the first control line 12 to control the operation of the large winch 3.

[0020] Each vertical column has a vertical steel guide cable 4 installed on the side closest to the heavy structure 1. The top end of the steel guide cable 4 is fixedly connected to the top of the roof plate, and the bottom end is fixedly connected to the ground. The steel guide cable 4 and the vertical column are parallel to each other in the vertical direction. Multiple steel hoops 14 are sequentially fitted over the vertical column and the steel guide cable 4 from top to bottom. When the steel guide cable 4 is subjected to a horizontal force away from the vertical column, the steel hoops 14 constrain the steel guide cable 4 in the horizontal direction. A first reflective diaphragm 15 is provided on the outer ring of the steel hoop 14. Each steel guide cable 4 is fitted with a movable hook 31 that can move up and down along the steel guide cable 4. There is a gap between the steel guide cable 4 and the vertical column that allows the movable hook 31 to move up and down. Even when the steel guide cable 4 is constrained, there is still a gap between the steel guide cable 4 and the vertical column that allows the movable hook 31 to move up and down.

[0021] A microcomputer 11 is installed at the bottom of the heavy-duty structure 1, and three small winches 37 are fixedly mounted at each of the four corners. The microcomputer 11 is connected to the three small winches 37 via signal communication. Each small winch 37 is connected to its corresponding movable hook 31 via a guy rope 30, i.e., one end of the guy rope 30 is connected to the small winch 37, and the other end is connected to the movable hook 31. By controlling the operation of the small winches 37 through the microcomputer 11, each guy rope 30 can be kept taut. At the same time, because the movable hooks 31 are constrained on the steel guide cable 4, the heavy-duty structure 1 is restrained, preventing swaying. A lidar 10 is also installed on the heavy-duty structure 1.

[0022] Each movable hook 31 is also equipped with an upper guide rope 9, a first lower guide rope 32, and a second lower guide rope 38. The lower end of the upper guide rope 9 is connected to the movable hook 31, and the upper end is connected to the first small winch 6. The operation of the first small winch 6 drives the upper guide rope 9 to move up and down, which in turn drives the movable hook 31 to move up and down, giving the movable hook 31 a tendency to move towards the heavy structure 1. Two sets of control devices are respectively installed on the ground near each vertical column. Each set of control devices includes a second small winch 34, a second control line 35, and a second controller 36. The second controller 36 controls the operation of the second small winch 34 through a signal connection with the second small winch 34 via the second control line 35. One set of control devices controls the up-and-down movement of the first lower guide rope 32, the upper end of which is connected to the upper rod of the movable hook 31. Another set of control devices controls the up-and-down movement of the second lower guide rope 38, the upper end of which is connected to the lower rod of the movable hook 31. Both the first and second lower guide ropes 32 and 38 tend to move the movable hook 31 away from the heavy structure 1. By controlling the upper guide rope 9, the first lower guide rope 32, and the second lower guide rope 38, the movable hook 31 can not only move up and down, but also move forward, backward, left, and right.

[0023] like Figure 3The movable hook 31 shown includes a U-shaped rigid block 16, a second rigid block 17, and a third rigid block 18 with the opening facing the steel guide cable 4. The length of the upper rod of the first rigid block 16 is greater than the length of the lower rod, and a through hole is provided at the left end of the upper rod. The first rigid block 16, the second rigid block 17, and the third rigid block 18 are connected in sequence. One end of the second rigid block 17 is connected to the left end of the lower rod of the first rigid block 16 through a first elastic hinge 24, which causes the second rigid block 17 to open outward relative to the lower rod of the first rigid block 16. One end of the third rigid block 18 is connected to the other end of the second rigid block 17 through a second elastic hinge 25, which causes the third rigid block 18 to open outward relative to the second rigid block 17. A long strip-shaped permanent magnet 27 is fixedly installed at the other end of the third rigid block 18. The permanent magnet 27 passes through the through hole on the upper rod and is located above the upper rod. The long strip-shaped permanent magnet 27 and the third rigid block 18 form a "┏" shape. An electric controller 26, an electromagnet 28, and a wire 29 are installed on the right end of the upper rod. The electric controller 26 is electrically connected to the electromagnet 28 via the wire 29 to control the activation or deactivation of the electromagnet 28's magnetism. When the electromagnet 28's magnetism is activated, it attracts the permanent magnet 27, causing the movable hook 31 to form a closed loop. A first micro winch 19 and a second micro winch 20 are installed on the right end of the first rigid block 16. Steel rings 23 are installed on the inner sides of the lower rod of the first rigid block 16, the second rigid block 17, and the third rigid block 18. One end of a long guide wire 21 is connected to the second micro winch 20, and the other end passes through the steel rings 23 on the inner sides of the first rigid block 16, the second rigid block 17, and the third rigid block 18 in sequence, connecting to the permanent magnet 27. The movement of the second micro winch 20 drives the permanent magnet 27 to move up and down. One end of the short guide wire 22 is connected to the first micro winch 19, and the other end is connected to the second rigid block 17. The movement of the first micro winch 19 drives the second rigid block 17 to rotate clockwise or counterclockwise around the first elastic hinge 24. The upper and lower rods of the first rigid block 16 are both equipped with second reflective films.

[0024] The following are the operating procedures for this device.

[0025] Step 1: Connect the four hooks 8 to the heavy structure 1. Fix a third miniature winch 37 at each of the four corners of the bottom of the heavy structure 1, connecting one end of the guy rope 30 to the third miniature winch 37. Install a microcomputer 11 at the bottom of the heavy structure 1, connecting it to the third miniature winch 37. Simultaneously, install a lidar radar 10 on the heavy structure 1.

[0026] Step 2: Connect each movable hook 31 to its corresponding upper guide rope 9, first lower guide rope 32, second lower guide rope 38, and guy rope 30. Connect one end of the guy rope 30 to the third small winch 37.

[0027] Step 2: De-energize the electromagnet 28 with the electric controller 26, preventing the electromagnet 28 from attracting the permanent magnet 27; release the wire rope of the first miniature winch 19, causing the short guide line 22 to loosen. Under the action of the first elastic hinge 24, the second rigid block 17 rotates outward around the first rigid block 16, winding the wire rope of the second miniature winch 20, causing the long guide line 21 to tighten and pull the permanent magnet 27 downward, thereby opening the movable hook 31. By controlling the first lower guide rope 32 and the second lower guide rope 38, the steel guide cable 4 is positioned in the U-shaped opening of the opened movable hook 31, with the U-shaped opening facing the steel guide cable 4.

[0028] Step 3: Wind the wire rope of the first micro winch 19 to tighten the short guide line 22. Rotate the second rigid block 17 inward around the first rigid block 16 to release the wire rope of the second micro winch 20, so that the long guide line 21 is relaxed. Send the permanent magnet 27 upward into the through hole of the upper rod, so that the electric controller 26 energizes the electromagnet 28. The electromagnet 28 attracts the permanent magnet 27, thereby closing the movable hook 31.

[0029] Step 4: Repeat the above operation so that the four movable hooks 31 are respectively hung on the four corresponding steel guide cables 4.

[0030] Step 5: Send a command via WiFi 13 to the third controller 39 on the top plate, controlling the large winch 3 on the top plate to pull the steel cable 5. The heavy structure 1 begins to rise slowly. At the same time, the first controller 7 on the top plate also receives a command, controlling the first small winch 6 to pull the upper guide rope 9 so that the movable hook 31 rises synchronously with the heavy structure 1. During the lifting process, the heavy structure 1 will be subjected to wind load. Since the guy ropes 30 connected around the heavy structure 1 restrict its horizontal displacement, the cable-winding effect is achieved. During the cable-winding process, the guy ropes 30 under tension will generate lateral tension on the steel guide cable 4 through the movable hook 31, causing it to deviate and deform. The steel hoop 14 effectively restricts the deviation of the steel guide cable 4. The presence of the steel hoop 14 obstructs the upward movement of the movable hook 31 along the steel guide cable 4. The opening and closing structure design of the movable hook 31 solves the obstruction problem and ensures the cable-winding effect of the cable-winding device for lifting the heavy structure 1.

[0031] Step 6: The lidar 10 monitors the lifting position of the heavy structure 1 and the movable hook 31 in real time by scanning the first reflective diaphragm 15 installed on the steel hoop 14 and the second reflective diaphragm 33 installed on the movable hook 31. When the movable hook 31 is about to pass through the steel hoop 14, the lidar 10 sends a signal to the electrical controller 26 via WiFi 13.

[0032] Step 7: Repeat step 2.

[0033] Step 8: Repeat step 3.

[0034] Step 9: Repeat step 5.

[0035] Step 10: Repeat steps 6, 7, 8, and 9 until heavy structure 1 is pulled up to the top.

[0036] The system sends commands to the controllers of each device via WiFi 13, and the devices then perform the next action according to the commands, enabling the entire system to operate in a coordinated manner. The movable hook 31 automatically repeats the above opening and closing process, thereby avoiding the tedious process of repeatedly untying and re-tying the guy ropes 30 during the hoisting of the heavy structure 1, and achieving the effect of guy ropes, greatly improving construction efficiency and optimizing the economic efficiency of the construction process.
