Description

Technical Field

[0001] This utility model belongs to the field of architectural engineering design technology, and specifically relates to a telescopic composite slab hoisting tool. Background Technology

[0002] In the process of modern industrialized construction, composite slabs are widely used as common precast components. However, there are many problems with the hoisting of composite slabs. For example, traditional hoisting tools cannot ensure the stability of composite slabs during hoisting, and they are prone to swaying and tilting. Moreover, multiple people are required to carry out the hoisting, which may not only damage the composite slabs themselves, but also pose significant safety hazards and easily lead to safety accidents. In addition, the specifications and dimensions of composite slabs vary in different projects, and existing hoisting tools are often not versatile enough to flexibly adapt to composite slabs of various specifications. Therefore, there is a need for a composite slab hoisting tool that can overcome the above defects, reduce the number of construction workers, ensure personnel safety, and be flexible enough to adapt to composite slabs of different sizes and specifications. Utility Model Content

[0003] The purpose of this invention is to provide a telescopic composite slab hoisting tool that can stably hoist composite slabs of different sizes and specifications.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A telescopic composite slab hoisting tool includes two symmetrically arranged connecting beams that can move relative to each other under the action of a second adjusting component. The connecting beams are hollow structures with a transverse straight groove in the middle. The straight groove is connected to two support shafts that can move relative to each other under the action of a first adjusting component through an internal sliding component. The support shafts are perpendicular to the connecting beams. The bottom of the sliding component is provided with a placement component that can move laterally and longitudinally with the connecting beams and support shafts. Lifting frames are also provided at both ends of the top of the connecting beams.

[0006] A further improvement of this utility model is that the sliding component includes a supporting slide rail located inside the strip-shaped straight groove. The supporting slide rail is U-shaped, and its outer wall is fixedly connected to the inner wall of the strip-shaped straight groove. The area between the two supporting slide rails is a through groove, and two hollow, slidable sliding blocks that match and engage with it are provided in the through groove. The sliding blocks are connected to the support shaft through a sleeve seat fixedly embedded inside them.

[0007] A further improvement of the present invention is that: a limiting protrusion is provided on the inner ring of the sleeve seat, and an axial engaging groove is provided on the surface of the support shaft, and the limiting protrusion and the engaging groove are matched and connected.

[0008] A further improvement of the present invention is that the first adjustment component includes four single-axis connecting frames symmetrically fixed in the middle of the two support shafts. Each single-axis connecting frame is hinged with an internal transmission arm located between the two support shafts. The other ends of the two internal transmission arms on the same side of the connecting beam are hinged together on the double-axis connecting frame. The two double-axis connecting frames are connected by a first double-headed adjusting screw through a thread.

[0009] A further improvement of the present invention is that the second adjustment component includes a fixed horizontal plate located at the middle position of the top of the connecting crossbeam, and the fixed horizontal plates are connected by a threaded connection to a second double-headed adjusting screw with an adjusting wheel installed at one end.

[0010] A further improvement of the present invention is that the placement component includes a hand chain hoist that is hooked to the bottom of the sliding block via a connecting hook, and a lifting hook is also installed at the bottom of the hand chain hoist.

[0011] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0012] The sliding block of this utility model is provided with a placement component below it. The first adjustment component allows the support shaft to move along the connecting beam, thereby moving the placement component to accommodate the hoisting of composite slabs of different widths. The second adjustment component allows the connecting beam to move along the support shaft, thereby moving the placement component to accommodate the hoisting of composite slabs of different lengths. The hand-operated hoist in the placement component can adjust the distance between the connecting hook and the lifting hook, thereby adjusting the distance between the composite slab body and the connecting beam, making it widely applicable.

[0013] This utility model has four placement components, which hook onto the four corners of the rectangular composite plate during lifting, ensuring a stable lifting process. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to embodiments:

[0019] Please see Figure 1-4 This utility model provides a telescopic tool for quick lifting of composite slabs, including two symmetrically distributed connecting beams 1. Lifting frames 9 are symmetrically fixedly connected to the top edges of both connecting beams 1. Before use, the lifting frames 9 are connected to the connecting ends of the lifting device. The tool can be lifted by the lifting frame 9 through the starting device. A strip-shaped straight groove 2 is opened in the middle of the side of each of the two connecting beams 1, penetrating the connecting beams 1. A sliding connecting assembly is slidably connected inside the strip-shaped straight groove 2. A first adjusting assembly is driven to the middle of the sliding connecting assembly. A second adjusting assembly is driven to the middle of the top of the two connecting beams 1. A placement assembly is movably connected to the bottom of the sliding connecting assembly.

[0020] Furthermore, the sliding connection assembly includes four supporting slide rails 4 symmetrically distributed inside the two strip-shaped straight slots 2. The supporting slide rails 4 are fixedly connected to the top and bottom walls of the strip-shaped straight slots 2, respectively. A through groove is opened in the middle of the supporting slide rail 4 located inside the strip-shaped straight slots 2 and fixedly connected to the bottom wall of the strip-shaped straight slots 2. The distance between the two supporting slide rails 4 located inside the same strip-shaped straight slot 2 is greater than the diameter of the support shaft 8. Two sliding blocks 5 are symmetrically slidably connected between the two supporting slide rails 4 located inside the same strip-shaped straight slot 2. All four sliding blocks 5 pass through the through groove opened in the middle of the supporting slide rail 4 fixedly connected to the bottom wall of the strip-shaped straight slot 2. The bottom end of the sliding block 5 is movably connected to the connecting hook 6.

[0021] Furthermore, each of the four sliding blocks 5 has a fixedly embedded sleeve seat 7. The inner wall of the sleeve seat 7 is fixedly connected with a limiting protrusion 20 at equal angles. The sleeve seat 7 is movably connected with a support shaft 8. The outer side of the support shaft 8 is provided with a locking groove 21 at equal angles. The locking groove 21 and the limiting protrusion 20 are matched and locked together. The limiting protrusion 20 and the locking groove 21 on the inner wall of the sleeve seat 7 slide inside.

[0022] Furthermore, the first adjustment assembly includes four single-axis connecting frames 11, which are symmetrically fixedly connected to the middle of the two support shafts 8. Each of the four single-axis connecting frames 11 has a transmission arm 12 rotatably connected inside, and a vertical shaft is fixedly connected inside the single-axis connecting frame 11. A circular through hole is opened at the middle of both ends of the transmission arm 12, and the vertical shaft passes through the circular through hole. Two double-axis connecting frames 13 are rotatably connected to the ends of the four single-axis connecting frames 11, and a first double-headed adjusting screw 14 is threaded between the two double-axis connecting frames 13. A threaded hole is opened in the middle of the double-axis connecting frame 13, and the threads at both ends of the first double-headed adjusting screw 14 match and engage with the threaded hole opened in the middle of the double-axis connecting frame 13.

[0023] Furthermore, the second adjustment assembly includes two fixed horizontal plates 15, which are respectively fixedly connected to the middle of the top of the two connecting beams 1. A second double-ended adjusting screw 16 is threaded between the two fixed horizontal plates 15. An adjusting wheel 17 is fixedly connected to one end of the second double-ended adjusting screw 16. A threaded hole is opened in the middle of the fixed horizontal plate 15. The threaded hole in the middle of the fixed horizontal plate 15 and the thread of the second double-ended adjusting screw 16 are matched and screwed together. The second double-ended adjusting screw 16 rotates and engages with the fixed horizontal plate 15, so that the two fixed horizontal plates 15 move closer and further away from each other on the second double-ended adjusting screw 16.

[0024] Furthermore, the placement assembly includes four lifting hooks 3, four connecting hooks 6, and four hand chain hoists 10. The four lifting hooks 3 and four connecting hooks 6 are respectively connected to the two ends of the four hand chain hoists 10. The hand chain hoists 10 are configured to adjust the distance between the two lifting hooks 3 and the connecting hooks 6, thereby adjusting the distance between the composite plate body 18 and the connecting beam 1. The connecting hooks 6 at the top of the hand chain hoists 10 are movably connected to the sliding block 5. The connecting hooks 6 are hooked into the sliding block 5 to achieve a movable connection. The lifting hooks 3 at the bottom of the hand chain hoists 10 are movably connected to the composite plate connecting plate 19. The bottom end of the composite plate connecting plate 19 is fixedly connected to the composite plate body 18. The composite plate connecting plate 19 is fixedly installed inside the composite plate body 18.

[0025] Instructions for use: Before placing the stacked plate, rotate the first double-headed adjusting screw 14. The rotation of the first double-headed adjusting screw 14 engages with the two double-shaft connecting frames 13, causing the two double-shaft connecting frames 13 to move closer or further apart along the first double-headed adjusting screw 14. When the double-shaft connecting frames 13 move further apart, the included angle between the two transmission arms 12 rotatably connected to the same double-shaft connecting frame 13 decreases, causing the two support shafts 8 to move closer together. At the same time, the sliding block 5 slides inside the supporting slide rail 4, and the connecting hook 6 and the sleeve seat 7 move accordingly, thereby driving the hand chain hoist 10 to move. When the double-shaft connecting frames 13 move closer together, the included angle between the two transmission arms 12 rotatably connected to the same double-shaft connecting frame 13 increases, causing the two support shafts 8 to move closer together. The sliding blocks 5 slide inside the supporting slide rail 4 while moving away from each other. The connecting hook 6, the sleeve seat 7, and the hand hoist 10 follow the movement. At the same time, the second double-headed adjusting screw 16 is rotated according to the specifications of the composite plate. When the second double-headed adjusting screw 16 rotates, it engages with the fixed horizontal plate 15, causing the fixed horizontal plate 15 to move away from or closer to each other. During this process, the fixed horizontal plate 15 drives the connecting beam 1 and the supporting slide rail 4 to move, causing the sliding blocks 5 to slide along the support shaft 8. During this process, the sleeve seat 7 and the limiting protrusion 20 slide outside the support shaft 8, while driving the connecting hook 6, the sleeve seat 7, and the hand hoist 10 to move. Then, the lifting hook 3 and the composite plate connecting hanging plate 19 on the composite plate body 18 are connected to start the lifting.
