Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a building construction hoisting device. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site of construction work is called the "construction site" or "worksite." Lifting refers to the installation and positioning of equipment using cranes or hoisting mechanisms. Currently, there is a lack of a mechanism that can quickly connect cranes or hoisting mechanisms to equipment or goods, thereby reducing loading and fixing time, improving lifting efficiency, and assisting in safe lifting operations. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a construction hoisting device that solves the problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, a construction hoisting device includes a body, a top fixed to the upper surface of the body, a spring fixed to the lower surface of the body, a base plate fixed to the bottom end of the spring, a central column fixed at the center of the upper surface of the base plate inside the spring, the top end of the central column extending through to the top of the top of the body, twelve supports fixed to the lower surface of the top of the body inside the body, the twelve supports being divided into six groups, a rotating shaft being fixed between two supports in each group, a gear a first fixed to the outer surface of the rotating shaft, a lever fixed to the outer surface of the rotating shaft inside the gear a first fixed to the gear a first fixed to the outer surface of the rotating shaft, a rotating cylinder slidably connected to the outer surface of the lever, a crossbeam rotatably connected to the bottom end of the rotating cylinder, six crossbeams extending to the outer side of the body at opposite ends, a horizontal plate slidably connected to the inside of the crossbeams, a vertical plate fixed to the end of the horizontal plate away from the body, a vertical frame slidably connected to the outer surface of the vertical plate, a base frame fixed to the bottom end of the vertical frame, and a support clamp plate rotatably connected to the inside of the base frame.

[0005] Furthermore, a recessed groove is formed on the upper surface of the machine top, and four sliding grooves are formed on the outer side of the recessed groove on the upper surface of the machine top. The sliding grooves are connected to the interior of the recessed groove. Slides are formed on both the left and right sides of the interior of the sliding groove. An inner groove is formed on the right side of the lower surface of the recessed groove. A rotating ring is rotatably connected inside the recessed groove. Four inclined grooves are formed on the upper surface of the rotating ring. Push rods are slidably connected inside the inclined grooves. Several toothed grooves are formed on the lower surface of the rotating ring. A rotating rod is rotatably connected inside the inner groove. A second gear is fixed on the outer surface of the rotating rod. The second gear is meshed with the rotating ring through the toothed grooves. A sliding rod is slidably connected inside the two sliding grooves. A sliding plate is fixed on the side of the sliding rod near the central column. The top of the push rod is fixedly connected to the lower surface of the sliding plate. Frame plates are symmetrically fixed on the upper surface of the sliding plate. A fixed shaft is fixed between the two frame plates. A pawl is rotatably connected to the outer surface of the fixed shaft. A torsion spring is fixed together on the outer surface of the fixed shaft and inside the pawl.

[0006] Furthermore, a stop block is fixed to the upper surface of the skateboard below the pawl.

[0007] Furthermore, the outer surface of the central column is provided with several annular grooves, through which the central column is respectively connected to four pawls and six gears.

[0008] Furthermore, multiple support frames are fixed to the outer side of the top surface of the machine, and a top plate is fixed to the top of the multiple support frames. A hanging ring is fixed at the center of the upper surface of the top plate.

[0009] Furthermore, the right end of the rotating rod extends through to the outer surface of the top of the machine and is fixed with an operating block.

[0010] Furthermore, the upper surface of the horizontal plate is provided with several screw holes, and the upper surface of the horizontal frame is provided with a bolt. The bottom end of the bolt is located inside the adjacent screw hole, and the bolt is threadedly connected to the screw hole.

[0011] Furthermore, the vertical plate has several threaded holes, and the vertical frame has bolts on its outer side. The end of the bolt near the support plate is located inside the adjacent threaded hole, and the bolt is threadedly connected to the threaded hole.

[0012] Furthermore, rubber pads are fixed to both the support plate and the side of the base frame near the central column.

[0013] Furthermore, the top of the support plate has a sloping structure, and the bottom of the support plate has a rounded structure.

[0014] The beneficial effects of the construction hoisting device of the present invention are as follows:

[0015] In use, the external crane is connected to the lifting device via a hanging ring. When lifting goods, the lifting device is positioned above the goods and then lowered. Once the bottom plate contacts the top of the goods, the lifting device descends under its own weight and the operator's input. Under this pushing force, the central column rises relative to the load, compressing the spring. The rising annular groove drives gear one, the rotating shaft, the lever, and the rotating drum to rotate. The rotating drum, in conjunction with the horizontal frame, horizontal plate, vertical plate, vertical frame, and support plate, moves the gripper mechanism inward, thus clamping the outer wall of the goods. Simultaneously, the rising central column engages with the annular groove at different positions via the pawl, maintaining its position and preventing reset movement, ensuring the gripper mechanism remains in contact with and clamps the goods. When unloading is required, the operator rotates the lever and gear two via the operating block. The gear two meshes with the tooth groove... The connecting ring rotates, and the rotating inner wall of the inclined groove presses against the guide rod, which moves outward along the inclined groove. Driven by the guide rod, the sliding plate moves accordingly, and the pawl disengages from the annular groove, releasing the restriction on the central column. This allows the lifting device to be moved upward and the connection to the cargo to be released. When encountering gaps at the bottom and heavy cargo, to ensure lifting safety, the support plate can be rotated to a horizontal position. During operation, the support plate should be aligned with the bottom of the cargo for support, thus facilitating lifting. When encountering cargo of different shapes, according to the cargo's shape, the bolt in the corresponding gripper mechanism can be rotated out, and the corresponding horizontal plate and other structures can be pulled out to separate them from the main body, thus preventing obstruction of protruding parts of the cargo. The length of the gripper mechanism in different positions can also be adjusted according to actual needs, making the lifting device more versatile and flexible in various applications.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0030] like Figure 1-11As shown, according to one aspect of the present invention, a construction hoisting device is provided, comprising a body 1, a top 2 fixed to the upper surface of the body 1, a spring 3 fixed to the lower surface of the body 1, a base plate 4 fixed to the bottom end of the spring 3, a central column 5 fixed at the center of the upper surface of the base plate 4 inside the spring 3, the top end of the central column 5 extending through to the top 2, and twelve supports 6 fixed to the lower surface of the top 2 inside the body 1, the twelve supports 6 being divided into six groups, with a rotating shaft 7 fixed between two supports 6 in each group, a gear 8 fixed to the outer surface of the rotating shaft 7, and the outer surface of the rotating shaft 7 being... A lever 9 is fixed inside the gear 8. A rotating cylinder 10 is slidably connected to the outer surface of the lever 9. A crossbeam 11 is rotatably connected to the bottom end of the rotating cylinder 10. The six crossbeams 11 extend to the outside of the machine body 1 at opposite ends. A cross plate 12 is slidably connected inside the crossbeam 11. A vertical plate 13 is fixed to the end of the cross plate 12 away from the machine body 1. A vertical frame 14 is slidably connected to the outer surface of the vertical plate 13. A base frame 15 is fixed to the bottom end of the vertical frame 14. A clamping plate 16 is rotatably connected inside the base frame 15. The crossbeams 10, cross plate 12, vertical plate 13, vertical frame 14, and clamping plate 16 form a gripper mechanism.

[0031] In this embodiment, a recessed groove 17 is formed on the upper surface of the top of the machine 2. Four sliding grooves 18 are formed on the outer side of the recessed groove 17 on the upper surface of the top of the machine 2. The sliding grooves 18 are connected to the interior of the recessed groove 17. Slides 19 are formed on both the left and right sides of the interior of the sliding grooves 18. An inner groove 20 is formed on the right side of the lower surface of the interior of the recessed groove 17. A rotating ring 21 is rotatably connected inside the recessed groove 17. Four inclined grooves 22 are formed on the upper surface of the rotating ring 21. Push rods 23 are slidably connected inside the inclined grooves 22. Several toothed grooves 24 are formed on the lower surface of the rotating ring 21. A rotating rod 2 is rotatably connected inside the inner groove 20. 5. Gear 26 is fixed on the outer surface of the rotating rod 25. Gear 26 is meshed with the rotating ring 21 through the tooth groove 24. Slide rod 28 is slidably connected inside the two slide rails 19. Slide plate 27 is fixed on the side of slide rod 28 near the central column 5. The top of push rod 23 is fixedly connected to the lower surface of slide plate 27. Frame plate 29 is symmetrically fixed on the upper surface of slide plate 27. Fixed shaft 30 is fixed between the two frame plates 29. Pad 31 is rotatably connected to the outer surface of fixed shaft 30. Torsion spring 32 is fixed together on the outer surface of fixed shaft 30 and inside pad 31.

[0032] In this embodiment, a stop block 33 is fixed on the upper surface of the slide plate 27 below the pawl 31. The stop block 33 limits the pawl 31 to prevent it from losing the support of the central column 5 and rotating inward under the action of the torsion spring 32 after the slide plate 27 moves outward, thus affecting the subsequent continuous movement.

[0033] In this embodiment, the outer surface of the central column 5 is provided with several annular grooves 51. The central column 5 is connected to four pawls 31 and six gears 8 through the annular grooves 51. The pawls 31 make the central column 5 slide upward and not downward, and drive the gears 8 to rotate.

[0034] In this embodiment, multiple support frames 34 are fixed on the outer side of the upper surface of the top 2, and a top plate 35 is fixed on the top of the multiple support frames 34. A hanging ring 36 is fixed at the center of the upper surface of the top plate 35, and the external lifting mechanism can be easily connected to the hoisting device through the hook and the hanging ring 36.

[0035] In this embodiment, the right end of the rotating rod 25 extends through to the outer surface of the top of the machine 2 and is fixed with an operating block 37, which allows the rotating rod 25 to be rotated easily by operating the operating block 37.

[0036] In this embodiment, the upper surface of the horizontal plate 12 is provided with a plurality of screw holes 38, and the upper surface of the horizontal frame 11 is provided with bolts 39. The bottom end of the bolts 39 is located inside the adjacent screw holes 38, and the bolts 39 are threadedly connected to the screw holes 38. By connecting the bolts 39 to the screw holes 38 at different positions, the overall length of the vertical plate 13 and the vertical frame 14 can be adjusted to accommodate goods of different widths.

[0037] In this embodiment, a plurality of screw holes 40 are provided through the interior of the vertical plate 13, and bolts 41 are provided through the exterior of the vertical frame 14. One end of the bolt 41 near the support plate 16 is located inside the adjacent screw hole 40, and the bolt 41 is threadedly connected to the screw hole 40. By connecting the bolt 41 to the screw holes 40 at different positions, the overall length of the vertical plate 13 and the vertical frame 14 can be adjusted to accommodate goods of different heights.

[0038] In this embodiment, rubber pads 42 are fixed on the side of the clamping plate 16 and the base frame 15 near the central column 5. When clamping goods, the rubber pads 42 can better protect the surface of the goods from being scratched due to clamping, and can also increase the coefficient of friction to prevent the goods from slipping.

[0039] In this embodiment, the top of the pallet 16 is a sloping structure and the bottom of the pallet 16 is an arc-shaped structure, so that after the pallet 16 is rotated and placed horizontally, it can stably support the bottom of the goods under the action of the base frame 15, and the sloping surface makes it easy to insert into the bottom of the goods.

[0040] The working principle of this device is as follows: During use, the external hoisting equipment is connected to the hoisting device through the hanging ring 36. When hoisting goods, the structure is positioned above the goods and then lowered. When the bottom plate 4 contacts the top of the goods, under the weight of the hoisting device and the operation of the personnel, the machine body 1 descends and, under the pushing force, the central column 5 rises relative to it. The spring 3 is compressed, and under the action of the rising annular groove 51, it drives the gear 8, the rotating shaft 7, the lever 9, and the rotating drum 10 to rotate. Under the connection of the rotating drum 10, the gripper mechanism composed of the horizontal frame 10, the horizontal plate 12, the vertical plate 13, the vertical frame 14, and the support plate 16 moves inward together, thereby clamping the outer wall of the goods. At the same time, the rising central column 5 continuously engages with the annular groove 51 at different positions through the pawl 31. Under the action of the pawl 31, the position of the central column 5 is maintained, preventing reset movement and ensuring that the gripper mechanism maintains contact and clamping with the goods. When unloading is required, the personnel operate the operating block 37 to rotate the lever 25. As gear 26 rotates, the meshing connection between gear 26 and tooth groove 24 drives the rotating ring 21 to rotate. The inner wall of the rotating inclined groove 22 presses against the guide rod 23 and moves it outward along the inclined groove 22. Driven by the push rod 23, the sliding plate 27 moves accordingly, and the pawl 31 disengages from the ring groove 51, thereby releasing the restriction on the central column 5. The lifting device can then be moved upward, and the connection to the cargo can be released. When there is a gap at the bottom and the cargo is heavy, to ensure lifting safety, the support plate 16 can be rotated to make it horizontal. During operation, the support plate 16 is aligned with the bottom of the cargo to support it, thereby lifting. When encountering cargo of different shapes, according to the shape of the cargo, the bolt 39 in the corresponding gripper mechanism can be rotated out, and the corresponding horizontal plate 12 and other structures can be pulled out to separate them from the main body, so as not to obstruct the protruding parts of the cargo. The length of the gripper mechanism in different positions can also be adjusted according to actual needs.

[0041] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
