Description

Technical Field

[0001] The utility model relates to the technical field of hoisting mechanisms, in particular to a mobile hoisting mechanism for prefabricated components of prefabricated buildings. Background Art

[0002] A prefabricated building refers to a building assembled on site with prefabricated components. The advantages of this kind of building are fast construction speed, little restriction by climatic conditions, labor saving and improved building quality. Users can design and build their own houses by themselves. The walls are removable and reusable, and no construction waste will be generated due to wall demolition. The components used include exterior wall panels, interior wall panels, composite slabs, precast beams, precast columns, stair slabs, etc. It completes the building through a large number of on-site assembly operations, greatly reducing time and manpower compared with the original cast-in-place operation, meeting the requirements of green buildings. When assembling a prefabricated building, a hoisting mechanism is needed to hoist its exterior wall panels, interior wall panels and other plates. However, the existing hoisting mechanism can only hoist the plates to a certain height. After the staff disassemble the plates from the hoisting mechanism, they then erect the plates for assembly, which is time-consuming and laborious and greatly affects the assembly efficiency.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 4 shown, a mobile hoisting mechanism for prefabricated components of an assembled building includes a first hoisting plate 1 and a second hoisting plate 2 arranged corresponding to each other up and down. The upper end of the first hoisting plate 1 is rotatably connected to reel rods 11 arranged corresponding to both sides. The first hoisting plate 1 is provided with a first motor 14 for driving the rotation of the reel rods 11 on both sides. Both sides of the reel rod 11 are fixedly connected with reels 12. The reels 12 are fixedly connected with suspension ropes 13. The lower ends of the suspension ropes 13 are fixedly connected to the second hoisting plate 2. Through holes 18 for cooperating with the suspension ropes 13 are provided at the four corners of the first hoisting plate 1.

[0023] A second lifting plate 2 is fixedly connected to the upper end of an n-shaped frame 3. A clamp box 5 is slidably connected inside the n-shaped frame 3. The lower end of the clamp box 5 is an open end. A lifting cylinder for driving the clamp box 5 to slide is fixedly connected to the n-shaped frame 3. Adjusting holes 15 communicating with the clamp box 5 are provided on both sides of the second lifting plate 2. L-shaped clamping blocks are slidably connected inside the adjusting holes 15. A clamping mechanism for driving the L-shaped clamping blocks on both sides to slide is provided inside the clamp box 5. The clamping mechanism includes a bidirectional screw 9 rotatably connected inside the clamp box 5. Sliders 6 threadedly connected to both sides of the bidirectional screw 9 are respectively slidably connected to both sides inside the clamp box 5. The L-shaped clamping blocks on both sides are respectively fixedly connected to the lower ends of the sliders 6. The L-shaped clamping block includes a clamping plate 7 fixedly connected to the lower end of the slider 6 and a supporting plate 8 fixedly connected to the lower end of the clamping plate 7 and arranged vertically. Anti-slip lines are provided on the inner wall of the clamping plate 7 and the upper end surface of the supporting plate 8. A second motor 10 for driving the bidirectional screw 9 to rotate is fixedly connected to one side of the clamp box 5. At least one groove arranged in parallel with the clamp box 5 is provided on both sides of the bottom surface of the second lifting plate 2. Baffles 16 are slidably inserted inside the grooves. Screw holes communicating with the grooves are provided on the second lifting plate 2. Adjusting bolts 17 are threadedly connected inside the screw holes. The lower ends of the adjusting bolts 17 are rotatably connected to the upper ends of the baffles 16.

[0024] In specific use, place the second lifting plate 2 directly above the plate to be lifted. Start the second motor 10 to drive the bidirectional screw 9 to rotate. The bidirectional screw 9 drives the sliders 6 on both sides to approach each other. The sliders 6 on both sides drive the clamping plates 7 on both sides to approach each other, so that the supporting plates 8 on both sides extend into the bottom of the plate and at the same time the clamping plates 7 on both sides clamp both sides of the plate. Start the telescopic cylinder 4 to pull the clamp box 5 upward. The clamp box 5 drives the clamping plates 7 on both sides to lift upward along the adjusting holes 15, so that the plate is further clamped between the supporting plate 8 and the ground surface of the second lifting plate 2. Turn the adjusting bolts 17 on both sides. The adjusting bolts 17 push the baffles 16 on both sides to extend out of the grooves, so that the baffles 16 on both sides are placed on the other two sides of the plate to prevent the plate from sliding left and right and falling off the L-shaped clamping blocks. Drive the first lifting plate 1 to rise upward through the lifting mechanism. The first lifting plate 1 lifts the second lifting plate 2 and the plate upward for hoisting through the lifting rope 13. When reaching the assembly location, start the first motor 14 on the side far from the assembly location to drive the winding roller to rotate and wind up the lifting rope 13, so that one end of the second lifting plate 2 is lifted upward. Start the second motor 10 near the assembly point once to drive the winding rod 11 to rotate and unwind the lifting rope 13, and adjust the second lifting plate 2 to the vertical state. Then turn the adjusting bolts 17 on both sides to make the baffles 16 extend into the grooves for convenient assembly.
