Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, specifically a hoisting tool with a prefabricated capping. Background Technology

[0002] Precast coping refers to a 50 to 100 mm thick concrete structure poured on top of a masonry wall (if there are no other structures on top) to hold the top of the wall in place and prevent the masonry blocks (such as bricks) from loosening and falling due to weathering of the masonry mortar or vibration (such as wind or earthquake) or collision. During the installation of the coping, lifting equipment is used to move it to the top of the column roof. To improve the convenience of lifting the precast coping, clamping devices are used to assist in the lifting of the precast coping.

[0003] When hoisting equipment typically clamps and lifts precast caps, it moves the clamping mechanism to the top of the cap and controls the robotic arm to clamp the sides of the cap. To ensure safety during lifting, workers need to install positioning pins or anti-detachment ropes to limit the position of the precast cap and prevent it from falling off and causing safety hazards. However, this method requires manual operation, which is time-consuming and labor-intensive. Therefore, we propose a hoisting tool for precast caps. Utility Model Content

[0004] To address the shortcomings of existing precast coping hoisting tools, this utility model provides a precast coping hoisting tool that features automatic opening and closing of the clamping plate when the height of the clamping device is adjusted by the hoisting equipment. During the upward movement of the first inclined rod, the clamping plate is squeezed inward under the action of gravity, ensuring that the clamping plate clamps and limits the position of the substrate. This solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a hoisting tool for a precast capping, including a first inclined rod, a clamping plate for holding the precast capping is welded to the lower end of the first inclined rod, a first connecting column is movably installed in the middle of the two sets of clamping plates, a second inclined rod is installed at the top of the first inclined rod through the second connecting column, and a third connecting column is installed at the other end of the two sets of second inclined rods.

[0006] Preferably, a reinforcing plate is installed on one side of each of the two sets of first diagonal bars. The reinforcing plate includes two sets of inclined plates, each set of inclined plates is installed on the outside of one set of first diagonal bars, and a positioning pin is installed on the outside of the two sets of inclined plates.

[0007] Preferably, traction columns are fixedly connected to both sides of the upper part of the first connecting column, and the traction columns pass through the interior of the third connecting column.

[0008] Preferably, the traction column has an installation hole inside, and a limit pin is installed inside the installation hole. The limit pin is sleeved on the outside of the third connecting column.

[0009] Preferably, the clamping plate is L-shaped and is movably sleeved on both sides of the precast top.

[0010] Preferably, an mounting plate is installed on the outside of the third connecting column, nuts are installed on both sides of the third connecting column, a positioning hole is opened on the upper part of the mounting plate, and a crane lug is installed inside the positioning hole.

[0011] Compared with existing precast coping hoisting tools, this utility model has the following advantages:

[0012] 1. The hoisting tool for this precast coping uses a crane to move the clamping equipment. As the crane controls the clamping plate to move downward, the first and second inclined rods move downward under pressure, while the clamping plate expands outward. The clamping plate can also move to the side of the coping, and under the weight of the clamping plate, it engages with the lower end of the coping and applies pressure to the side of the coping. At the same time, the crane controls the equipment to move upward, and the clamping plate applies pressure to the side of the coping and clamps it in place. Then, when the coping is lifted, it can automatically clamp and loosen, quickly extend and retract to lock the coping module, and the hoisting stroke is self-locking and stable, and it can be quickly released when placed.

[0013] 2. The hoisting tool for the precast capping has a reinforcing plate installed on the side of the first diagonal bar. The reinforcing plate reinforces the sides of the first diagonal bar on both sides, improving the overall tensile strength of the first diagonal bar and extending the service life of the equipment. The traction column passes through the interior of the third connecting column, ensuring that the position between the first and third connecting columns remains stable. At the same time, a limit pin is installed inside the mounting hole. The limit pin drives the traction column to limit its position inside the third connecting column, ensuring its stability.

[0020] 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.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A hoisting tool for a precast capping includes a first inclined rod 1. The lower end of the first inclined rod 1 is welded with a clamping plate 2 for holding the precast capping. A first connecting column 3 is movably installed in the middle of the two sets of clamping plates 2. The first connecting column 3 defines the position between the two sets of first inclined rods 1. A second inclined rod 5 is installed at the top of the first inclined rod 1 through a second connecting column 4. A third connecting column 6 is installed at the other end of the two sets of second inclined rods 5. By pulling the third connecting column 6, the first inclined rod 1, under the action of gravity, drives the clamping plate 2 to clamp the position of the substrate, and then can automatically pick up and release the substrate.

[0022] refer to Figure 1 A reinforcing plate 8 is installed on one side of each of the two sets of first inclined rods 1. The reinforcing plate 8 includes two sets of inclined plates, each set of inclined plates being installed outside one set of first inclined rods 1. Positioning pins are installed on the outside of the two sets of inclined plates. With the reinforcing plate 8 installed outside the two sets of first inclined rods 1, when the control device moves downward and the clamping plate 2 is clamped outside the pressure top, when the clamping device moves upward, the lower end of the first inclined rod 1 retracts inward, and the sides of the two sets of first inclined rods 1 are spread open. This allows the reinforcing plate 8 to apply pressure to the side of the substrate and clamp and limit the position of the pressure plate. At the same time, the reinforcing plate 8 supports and limits the position between the two sets of first inclined rods 1. The reinforcing plate 8 strengthens the strength between the two sets of first inclined rods 1, preventing the reinforcing plate 8 from being subjected to excessive pressure, which could lead to deformation and damage.

[0023] refer to Figure 5The upper two sides of the first connecting column 3 are fixedly connected to the traction column 9. The traction column 9 passes through the interior of the third connecting column 6. By controlling the traction column 9 installed on the upper part of the first connecting column 3 to pass through the third connecting column 6, the positions of the first connecting column 3 and the third connecting column 6 are kept in a stable state, effectively avoiding the problem of deformation of the clamping equipment after long-term use.

[0024] refer to Figure 5 The traction column 9 has an installation hole 10 inside, and a limit pin 11 is installed inside the installation hole 10. The limit pin 11 is sleeved on the outside of the third connecting column 6. After the control clamp 2 clamps the substrate and lifts it upward, the position between the first connecting column 3 and the third connecting column 6 is adjusted to ensure the stability of the substrate clamping. The limit pin 11 can be installed inside the installation hole 10 and sleeved on the outside of the third connecting column 6, so that the position of the traction column 9 inside the third connecting column 6 can be kept in a stable state.

[0025] refer to Figure 3 The clamping plate 2 is L-shaped and is movably sleeved on both sides of the precast pressure top. Because the clamping plate 2 is L-shaped, after the lower end of the first inclined rod 1 is moved to both sides of the substrate, the lower end of the clamping plate 2 can be sleeved on the lower part of the substrate, thereby limiting the position of the substrate and lifting the substrate.

[0026] refer to Figure 1 The third connecting column 6 is equipped with an mounting plate 7 on its exterior. Nuts are installed on both sides of the third connecting column 6. The mounting plate 7 has a positioning hole on its upper part, and a crane lug is installed inside the positioning hole. The mounting plate 7 is installed by sleeve through the middle of the third connecting column 6, and the position of the mounting plate 7 can be adjusted by the nuts. At the same time, the height of the lifting equipment can be adjusted by using a crane.

[0027] Working principle: In use, after connecting the mounting plate 7 to the crane, the crane controls the height adjustment of the mounting plate 7. When the crane moves the first inclined rod 1 downward, it controls the first inclined rod 1 to contact the substrate. At the same time, the first inclined rod 1 and the second inclined rod 5 deform under pressure, causing the lower end of the first inclined rod 1 to extend outward. Simultaneously, the clamping plate 2 moves to the outside of the substrate, controlling the clamping plate 2 to limit the position of the substrate. When the equipment is lifted upward, the clamping plate 2 automatically retracts inward, that is, the clamping plate 2 can automatically clamp the substrate. At the same time, when the crane moves the first inclined rod 1 upward, it can automatically lift the substrate. After the equipment lifts the substrate, the reinforcing plate 8 strengthens the tensile strength of the first inclined rod 1, reducing the deformation of the first inclined rod 1 due to excessive tension. At the same time, a limiting pin 11 can be installed inside the traction column 9 to limit the length between the first connecting column 3 and the third connecting column 6, effectively preventing the first inclined rod 1 from deforming during the lifting process, which would cause the clamping of the substrate to loosen.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
