Technical Field

[0001] This utility model belongs to the field of precast concrete, specifically a prefabricated flat-top installation and hoisting device. Background Technology

[0002] With the increasing demands of urban development, prefabricated subway stations, with their green, low-carbon, and short construction period characteristics, are gradually being applied to the field of urban rail transit construction.

[0003] In the assembly and construction of flat-roofed, large-block subway stations, setting up large-volume precast concrete components can reduce the gaps between joints. However, if large-volume precast concrete components are used as support columns, they need to be laid horizontally during precasting, and the support columns need to be kept vertical during installation. Due to the large volume of the precast components, it is difficult to flip them in space. Therefore, a hoisting device that can facilitate the spatial flipping of large-volume precast concrete components is needed. Utility Model Content

The hoisting threaded sleeve 3 is divided into two groups: one group is located at the center of the horizontal hoisting surface, and the other group is perpendicular to the center of the side wall of the horizontal hoisting surface. A lifting ring 4 is threaded into the internal part of the hoisting threaded sleeve 3. The hoisting mechanism 1 also includes a balance beam 5. Two sets of hooks 6 are provided at the bottom end of the balance beam 5. A winding mechanism 7 is provided between the hooks 6 and the balance beam 5. A hoisting rope 8 is provided on the outer surface of the winding mechanism 7. The hoisting rope 8... The bottom end is fixedly connected to the hook 6. The two sets of hooks 6 are respectively sleeved inside the two lifting rings 4. The winding mechanism 7 includes a gearbox 701. The input end of the gearbox 701 is equipped with a motor 702. The output end of the gearbox 701 is fixedly installed with a gear 703. The outer side of the gear 703 is meshed with a toothed winding wheel 704. The toothed winding wheel 704 has teeth on the two rims of the winding wheel. The toothed winding wheel 704 is rotatably connected to the balance beam 5. The motor 702 and the gearbox 701 are fixedly connected to the balance beam 5.

[0022] The front and rear sides of the balance beam 5 are fitted with sliding sleeves 706. The motor 702 and gearbox 701 are fixedly installed on the outer surface of the sliding sleeves 706. The inner side of the balance beam 5 is provided with a sliding groove 707. Two sliding blocks 708 are slidably connected inside the sliding groove 707. Two toothed spools 704 are rotatably connected to the bottom of the two sliding blocks 708 respectively. The sliding blocks 708 are fixedly connected to the sliding sleeves 706. Motors 709 are fixedly installed on both sides of the balance beam 5. A lead shaft 710 is fixedly installed at the output end of the motor 709. The lead shaft 710 is slidably connected to one sliding block 708 and meshes with the other sliding block 708. Through this arrangement, the position of the sliding sleeves 706 can be changed. By changing the position of the two sliding sleeves 706 at the same time, the balance beam 5 is kept horizontal, and the hoisting traction rope 12 is finally located at the center of the balance beam 5.

[0023] A limiting groove 705 is provided on the outer surface of the balance beam 5, and the sliding sleeve 706 is slidably connected to the limiting groove 705. This setting can limit the movement range of the sliding sleeve 706.

[0024] The component 2 is located opposite the horizontal lifting surface. An auxiliary lifting threaded sleeve 9 is provided at the end of the lifting threaded sleeve 3 away from the side wall. The lifting ring 4 is threaded inside the auxiliary lifting threaded sleeve 3. By providing the auxiliary lifting threaded sleeve 9, it can be connected to the external traction mechanism to rotate the component 2 from the side when the component 2 is tilted.

[0025] The hoisting mechanism 1 includes a boom 10. The front end of the boom 10 is provided with multiple sets of reversing wheels 11. The outer surface of the reversing wheels 11 is fitted with a traction rope 12. The traction rope 12 is fixedly connected to the balance beam 5. This arrangement can ensure that the balance beam is subjected to uniform force.

[0026] The sliding groove 707 has a "T" shaped cross section. The bottom end of the sliding block 708 extends to the bottom of the sliding groove 707. A groove is provided at the bottom end of the sliding groove 707. The toothed coil wheel 704 is rotatably connected inside the groove. This arrangement ensures that the sliding block 708 always keeps in contact with the balance beam 5, and the balance beam 5 can lift the sliding block 708.

[0027] In use, the following steps are taken: During the pouring of the precast concrete component 2, the lifting threaded sleeve 3 is pre-embedded inside the component 2. When the precast concrete component 2 is formed and demolded and needs to be lifted, the balance beam 5 is placed above the component 2, and the two hooks 6 are respectively sleeved inside the two lifting rings 4. The distance between the balance beam 5 and the component 2 is adjusted to allow the component 2 to rotate once. The component 2 is then lifted off the ground by the boom 10. The length of the lifting rope 8 connected to the middle of the component 2 is released, and the lifting rope 8 connected to the side wall of the component 2 is continuously wound up. At the same time, the sliding sleeve 706 where the lifting rope 8 connected to the side wall is located moves towards the center, and the sliding sleeve 706 on the other side moves in the same direction, keeping the balance beam 5 in a horizontal state. This arrangement allows the component 2 to undergo a spatial flip.
