Detailed Implementation

[0024] 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.

[0025] like Figure 1 , 2 As shown in Figure 3, Embodiment 1 provides a tool for vertically lifting ALC plates, including a movable frame 1 that provides installation support and a base for movement for the entire device. The front end of the movable frame 1 has a vertically sliding pallet 2 for supporting the ALC plate 3. The movable frame 1 is equipped with a lifting device 4 connected to the pallet 2 for traction, enabling vertical lifting of the pallet to meet construction lifting and relocation needs. The pallet 2 is equipped with a traction device 5 connected to a hook 6, which engages with the ALC plate 3 to prevent it from tipping over or slipping.

[0026] In use, the tool is first moved to the ALC board stacking position, then the goods support 2 of the tool is placed in the lowest position, and the ALC board is placed on the goods support, and the goods support supports the ALC board. Then the traction device is used to fix the ALC board placed on the goods support, so as to avoid unstable factors during lifting or moving, and to achieve the purpose of safety protection. Then the moving frame is controlled to move to the working surface, and then the lifting device 4 is started to adjust the height of the ALC board, so as to ensure that the position of the ALC board is at the appropriate construction height and position, and then the ALC board is unloaded to the construction position for construction. Then the tool is horizontally moved to the ALC board placing position for the next cycle of construction. The tool has simple structure, low manufacturing cost, and is safe, reliable and efficient in use.

[0027] As a further embodiment, in the embodiment, the moving frame 1 is a right-angled ladder-shaped frame, which is arranged in a right-angled ladder shape, can increase the liftable height, and according to the actual lifting height requirement, such as Figure 1 and Figure 3 , the lifting height and overall height can be changed by changing the length ratio of each side of the moving frame 1. Among them, the upper and lower bases of the right-angled ladder-shaped frame are vertically arranged, the goods support is vertically slidably arranged on the lower base, and the moving frame 1 is provided with a plurality of universal wheels 13, and the embodiment is provided with four universal wheels. By arranging the universal wheels, the tool can be easily pushed. In the embodiment, the right-angled ladder-shaped frame can be assembled by conventional steel pipes and fasteners commonly used on construction sites, or can be welded by conventional profiles, thereby reducing the production cost.

[0028] In addition, the goods support 2 is provided with a support 14, and the traction device 5 is arranged on the support 14 and is provided with at least two sets. In the embodiment, the traction device is provided with two sets, and the hooks connected by the two sets of traction devices are used to cooperate with the top of the ALC board on the goods support respectively, so that the ALC board can be fixed from multiple positions, thereby improving the safety performance during lifting and moving. The base of the traction device is installed on the goods support, so that the goods support can be lifted as a whole, and the construction stability is higher.

[0029] As a further embodiment, in order to further improve the stability during moving, a counterweight 20 is arranged on the moving frame 1, so as to avoid the safety and stability problems caused by the excessive increase of the overall center of gravity of the device due to the lifting of the ALC board.

[0030] In the embodiment 2, on the basis of the embodiment 1, the goods support 2 comprises a bottom support 7, one end of the bottom support 7 is connected with a backrest 8, the bottom support 7 and the backrest 8 are arranged in an L shape, and the backrest 8 is in sliding cooperation with the moving frame 1.

[0031] Specifically, as Figure 4As shown, guide rails 9 are symmetrically arranged on both sides of the movable frame 1, and rollers 10 that cooperate with the guide rails 9 are provided on the backrest 8. In this embodiment, the guide rails 9 are vertically arranged C-shaped channel steels, and the openings of the C-shaped channel steels on both sides face each other. The rollers 10 are rotatably arranged on the backrest 8. When the backrest is lifted and moved by the lifting device, the rollers 10 roll in the C-shaped channel steel to keep the movement direction of the backrest vertical.

[0032] As a further embodiment, the lifting device 4 includes a winch 11 fixedly mounted on the movable frame 1. The top of the movable frame 1 is provided with a pulley 12, and the traction rope of the winch 11 passes around the pulley 12 and is connected to the backrest 8.

[0033] In this embodiment, pulley 12 is a fixed pulley fixedly mounted on the top of the movable frame 1, and the fixed pulley is welded and fixed to the movable frame. When the ALC plate is relatively heavy, the fixed pulley can be replaced with a pulley block to reduce the traction force requirement of the winch. The winch controls the vertical position of the backrest pulled by the other end of the traction rope by its winding and unwinding actions, thereby achieving the lifting purpose.

[0034] Example 3, based on Example 2, such as Figure 5 As shown, the traction device 5 includes a winding shaft 15 rotatably mounted on a support 14, a ratchet mechanism is provided between the support 14 and the winding shaft 15, a pull rope is wound on the winding shaft 15, and the pull rope is connected to the hook 6.

[0035] Specifically, in this embodiment, the hook 6 is a J-shaped hook, and a handle 19 is provided at the end of the winding shaft 15. During use, the handle controls the rotation of the winding shaft to wind the pull rope. In this embodiment, when fixing the ALC plate, the ratchet mechanism is first released, the pull rope is pulled outwards a certain length, then the hook is connected to the ALC plate, the ratchet mechanism is reset, and finally the winding shaft is controlled to rotate, tightening the pull rope. After tightening, the ratchet mechanism can restrict the reverse rotation of the winding shaft, preventing the pull rope from becoming slack. The tightened state of the pull rope can maintain the ALC plate's fit against the backrest, improving stability and safety.

[0036] As a further real-time method, the ratchet mechanism includes a ratchet 16 fixedly mounted on the end of the winding shaft 15, a locking tongue 17 hinged to the support 14 to cooperate with the ratchet 16, and a spring 18 provided between the locking tongue 17 and the support 14.

[0037] When the winding reel rotates to release the pulling rope, the lock tongue is separated from the ratchet by manual operation, at this time the compression spring is lost to limit the ratchet. During the tightening of the pulling rope, the lock tongue is in contact with the ratchet under the resetting force of the compression spring, so that the ratchet can only rotate in one direction, and the reverse rotation of the ratchet is prevented, so as to achieve the locking purpose. By using the tool, the efficiency and quality problems in the traditional construction relying on manual operation in the ALC plate construction can be effectively solved, so as to improve the installation and construction efficiency of the ALC plate, reduce the construction time, improve the engineering quality, and improve the construction safety.

[0038] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
