AI Technical Summary
Existing hoisting equipment used in prefabricated building construction cannot adapt to changes in material size, resulting in high pressure on the middle of the material, making it prone to breakage, and it cannot be lifted from all directions to prevent damage.
It adopts a combination design of crossarm mechanism, limiting mechanism, anti-collision mechanism and tensioning mechanism. The extension mechanism works with the limiting mechanism to limit the movement, the crossarm mechanism to support the material, the tensioning mechanism to fix it, and the anti-collision mechanism to prevent collisions, so as to achieve all-round lifting of materials and adapt to the size of materials.
It enables free adaptation and all-round lifting of materials in prefabricated building construction, preventing material damage and improving the stability and safety of the hoisting process.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hoisting for prefabricated building construction, and in particular to a hoisting device for prefabricated building construction. Background Technology
[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. During the construction of prefabricated buildings, cranes are used to lift components to the construction location. In existing hoisting methods, steel cables are used to connect the joints on the components, usually four steel cables connecting the four corners of the components.
[0003] In existing hoisting devices for prefabricated building construction, such as the utility model patent with application number 202420982081.9, a hoisting device for prefabricated building construction is disclosed. This utility model uses hoisting steel ropes to hang the four corners of the component, moves the sliding plate so that the pressure strip overlaps with the upper surface of the component, fixes the position of the sliding plate with the first clamping bolt, then moves the position of the protective plate, and fixes the position of the protective plate with the adjusting strip by the second clamping bolt, and installs the connecting strip at the pressure strip. At this time, the protective plate blocks the two sides of the component. In the event of a collision, the T-shaped stop strip is subjected to force, the first spring is compressed to buffer, and thus the component is damaged.
[0004] However, during the hoisting process in prefabricated building construction, it is impossible to lift the materials, resulting in excessive pressure on the middle of the materials, which can easily lead to breakage, and it cannot adapt to the size of the materials. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a hoisting device for prefabricated building construction, which, by setting a crossbeam mechanism and a limiting mechanism, can freely adapt to the size of materials during the hoisting process of prefabricated building construction and can lift the materials from all directions to prevent damage.
[0006] This utility model provides a hoisting device for prefabricated building construction, including an extension mechanism; it also includes two sets of crossbeam mechanisms, four sets of limiting mechanisms, four sets of anti-collision mechanisms, and a tensioning mechanism. The two sets of crossbeam mechanisms are installed on the extension mechanism, the four sets of limiting mechanisms are installed on the extension mechanism, each set of limiting mechanisms is equipped with an anti-collision mechanism, and the tensioning mechanism is installed on the extension mechanism.
[0007] The extension mechanism extends, the crossbeam mechanism supports the crossbeam, the limiting mechanism limits the movement, the anti-collision mechanism prevents collisions, and the tensioning mechanism tightens the load. By using the extension mechanism in conjunction with the limiting mechanism for limiting the movement, the crossbeam mechanism for supporting the crossbeam, the tensioning mechanism for tightening and fixing the load, and the anti-collision mechanism for preventing collisions, the hoisting process used in prefabricated building construction can freely adapt to the size of materials and can lift materials from all directions to prevent damage.
[0008] Preferably, the extension mechanism includes a crossbar, two sets of extension arms, two sets of lead screws, two sets of bevel gears, and a bevel gear knob. The two sets of extension arms are slidably mounted on the crossbar, and the two sets of lead screws are rotatably mounted on the crossbar. Each set of lead screws is threadedly engaged with one set of extension arms. Each set of lead screws is equipped with a set of bevel gears. The bevel gear knob is rotatably mounted on the crossbar and meshes with the two sets of bevel gears. By rotating the bevel gear knob to mesh with the bevel gears, the bevel gears drive the lead screws to rotate. While the lead screws rotate, they engage with the extension arms threadedly, causing the extension arms to move and extend.
[0009] Preferably, the crossbar mechanism includes a slide bar and a support plate. The slide bar is slidably mounted on the crossbar, and the support plate is mounted on the slide bar. The slide bar limits the width of the material, and the support plate lifts the middle section of the material.
[0010] Preferably, the limiting mechanism includes a limiting arm and two sets of limiting arms. The limiting arm is rotatably mounted on the extension arm, and the two sets of pulleys are rotatably mounted on the limiting arm. The limiting arm limits the width of the material, and the pulleys limit the steel cable.
[0011] Preferably, the anti-collision mechanism includes an anti-collision block and a spring, wherein the anti-collision block is slidably mounted inside the limiting arm by the spring; the spring supports the anti-collision block to prevent collisions.
[0012] Preferably, the tensioning mechanism includes a steel cable, a screw, a knob, a rotating column, four sets of steel cables, and four sets of hooks. The steel cable is installed on the upper end of the crossbar, the screw is installed on the steel cable, the knob is threadedly connected to the screw, the rotating column is rotatably installed on the knob, and the four sets of steel cables are installed on the rotating column. Each set of steel cables has a set of hooks. The hooks hook the four corners of the material. By rotating the knob and screw, the knob drives the rotating column to move, thereby tightening the steel cables and fixing the material.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by using the extension mechanism in conjunction with the limiting mechanism for limiting, by using the crossbeam mechanism for crossbeam support, by using the tensioning mechanism for tensioning and fixing, and by using the anti-collision mechanism for anti-collision, the material size can be freely adapted during the hoisting process of prefabricated building construction, and the material can be lifted from all directions to prevent damage.
