Description

Technical Field

[0001] The utility model belongs to the field of building construction, and particularly relates to a hoisting device for prefabricated components. Background Art

[0002] Prefabricated structures use precast components as the main load-bearing components. First, precast components are manufactured in the factory. After completion and quality inspection, they are uniformly transported to the construction site for assembly and connection to form a concrete building structure. Compared with traditional in-situ construction, prefabricated structures are more in line with the green construction standards and are easy to ensure the construction quality.

[0003] In building construction, it is usually necessary to hoist prefabricated components to high floors for use. Different types of prefabricated components usually need to be hoisted at different positions. However, the existing hoisting frames usually have fixed lifting holes at the bottom, and the adaptability is poor. In addition, most prefabricated components require a certain installation angle during hoisting, and it is difficult to adjust the angle and balance with fixed lifting holes. Summary of the Utility Model

[0004] The purpose of the embodiment of the utility model is to provide a hoisting device for prefabricated components, aiming to solve the problems raised in the background art.

Detailed Embodiment

[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] The following describes in detail the specific implementation of the present utility model in combination with specific embodiments.

[0020] As Figures 1 to 3 shown, a hoisting device for prefabricated components provided by an embodiment of the present utility model includes a hoisting frame 1. The hoisting frame 1 includes a main hoisting hole 2 fixedly arranged at the upper end of the hoisting frame 1 for connecting with a hoisting machine, and further includes:

[0021] A hoisting unit 3. The hoisting unit 3 includes a slide rail 11 fixedly arranged at the lower end of the hoisting frame 1 and integrally formed with the hoisting frame 1. A plurality of hoisting blocks 4 are movably sleeved outside the slide rail 11. An installation groove 41 is fixedly arranged at the upper end inside the hoisting block 4. A plurality of rollers 5 are arranged in the installation groove 41. A roller groove 111 adapted to the rollers 5 is fixedly arranged at the upper end of the slide rail 11 corresponding to the position of the rollers 5. Auxiliary hoisting holes are fixedly arranged at the lower ends of the hoisting blocks 4, and a hook 7 is connected in the auxiliary hoisting holes;

[0022] A limiting unit 8. The limiting unit 8 includes limiting baffles 12 fixedly arranged at both ends of the hoisting frame 1. The limiting unit 8 further includes installation holes 42 fixedly arranged on both sides of the hoisting block 4. First limiting grooves 112 are fixedly arranged on both sides of the slide rail 11 corresponding to the positions of the installation holes 42. A second limiting groove 113 is arranged on one side of the first limiting groove 112. The head of a bolt 9 is movably arranged in the second limiting groove 113, and the threaded part of the bolt 9 passes through the first limiting groove 112 and the installation groove 41 and extends to the outside of the hoisting block 4 and is threadedly connected with a nut 10.

[0023] In an embodiment of the present utility model, the hoisting block 4 can slide along the slide rail 11. By cooperating with the auxiliary hoisting holes and the hook 7 arranged at the bottom of the hoisting block 4, various different prefabricated components can be adapted. By cooperating with the arranged bolt 9 and nut 10, the hoisting block 4 can be fixed. Then, by adjusting the positions of other unhooked hoisting blocks 4 and adding appropriate weights below them, the angle and balance of the device can be adjusted.

[0024] In an example of the present utility model, during use, first loosen the bolt 9 and the nut 10, adjust the hoisting block 4 to a suitable position, pre-tighten the bolt 9 and the nut 10, and conduct a trial hoist. Adjust the position of the hoisting block 4 so that the hoisting angle of the prefabricated component meets the requirements. Weights can also be hung below other unhooked hoisting blocks 4 and the positions are adjusted to reach the balanced position. After adjustment, tighten all the bolts 9 and nuts 10, and then the hoisting work can be officially started.

[0025] As Figure 1 and Figure 2As shown, as a preferred embodiment of the present utility model, the main lifting holes 2 are symmetrically arranged at the upper end of the lifting frame 1 with the midline of the lifting frame 1 as the axis of symmetry, and the secondary lifting holes are fixedly arranged at the center of the bottom surface of the lifting block 4. The slide rail 11 is arranged with a rectangular cross-section, and the lifting block 4 is arranged as a "U"-shaped block with an open upper end. The inner cross-section of the lifting block 4 is adapted to the cross-section of the slide rail 11.

[0026] In an example of the present utility model, the lifting block 4 sleeved outside the slide rail 11 is movable, facilitating the adjustment of the lifting of the prefabricated component by adjusting the position of the lifting block 4.

[0027] As Figure 2 shown, as a preferred embodiment of the present utility model, the roller 5 is arranged as a drum-shaped wheel with flat ends and a curved outer surface, and the roller groove 111 is arranged as a curved groove adapted to the roller 5. The limit baffle 12 is arranged as a plate-like structure, and the lowest end of the secondary lifting hole is higher than the bottom end of the limit baffle 12.

[0028] In an example of the present utility model, by arranging the roller 5 in cooperation with the roller groove 111, the friction between the lifting block 4 and the slide rail 11 is reduced, facilitating the movement of the lifting block 4. By arranging the limit baffle 12, the lifting block 4 can be limited, and when lifting is not required, the limit baffle 12 can also stand on the ground as a support leg, thereby providing appropriate protection for the lifting block 4 and the secondary lifting hole.

[0029] As Figure 2 and Figure 3 shown, as a preferred embodiment of the present utility model, the first limit groove 112 and the second limit groove 113 together form a "T"-shaped groove. The head of the bolt 9 is arranged as a square block adapted to the size of the second limit groove 113, and the width of the first limit groove 112 is the same as the diameter of the installation groove 41.

[0030] In an example of the present utility model, by arranging the first limit groove 112 in cooperation with the second limit groove 113 to form a "T"-shaped groove, the head of the bolt 9 can be stuck in the first limit groove 112. In cooperation with the arranged bolt 9 and nut 10, the lifting block 4 can be fixed. In addition, if an accident occurs where the bolt 9 and the nut 10 become loose during work, the friction between the bolt 9 and the second limit groove 113 and the installation groove 41 can also play a protective role.
