Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a steel hoisting device. Background Technology

[0002] In construction projects, steel needs to be hoisted primarily because individual pieces are heavy and long, and installation locations are typically at height. Safe and efficient horizontal and vertical transport cannot be achieved by manual labor alone; specialized lifting equipment such as tower cranes and truck cranes must be used to transfer steel from ground storage areas to the construction site. This ensures the progress of structural construction and reduces the safety risks associated with manual handling.

[0003] In existing steel hoisting operations in construction projects, especially for large steel plates, steel wire ropes are commonly used for hoisting or simple clamps are used for binding and fixing. These traditional methods have many drawbacks: First, the steel wire ropes come into direct contact with the sharp edges of the steel plates, which can easily cause shearing and wear during hoisting, posing a huge safety hazard. Therefore, we propose a steel hoisting device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a steel hoisting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel hoisting device includes a hook and a hoisting plate. Two steel wire ropes are sleeved on the outer wall of the hook. Two grooves are formed on the outer wall of the hoisting plate. Three shafts are fixedly connected to the inner walls of the two grooves. Pulleys are rotatably sleeved on the outer walls of the six shafts. Four of the pulleys are slidably connected to the outer walls of the two ends of the two steel wire ropes in pairs. Two metal sleeves are slidably connected to the outer walls of the two steel wire ropes. I-shaped shafts are slidably connected to the inner walls of the four metal sleeves. U-shaped parts are fixedly connected to the outer walls of the two ends of the four I-shaped shafts. Multiple connecting shafts are fixedly connected between two U-shaped parts. A round shaft is fixedly connected between two U-shaped parts. Clamps on steel plates are rotatably sleeved on the outer walls of the four round shafts. Hoisting components are provided on the outer walls of the U-shaped parts.

[0007] Preferably, the hoisting assembly includes four steel plate lower clamping plates, and each of the eight U-shaped parts has two sliding holes on its outer wall. The inner walls of the two sliding holes are slidably connected to the same bolt. The outer walls of the eight bolts are threaded with nuts, and the outer walls of the eight bolts are fitted with ear plates. The eight ear plates are fixedly connected to the bottom of the four steel plate lower clamping plates in pairs. The outer walls of the bolts are provided with pin holes, which cooperate with existing cotter pins to prevent the nuts from being unscrewed from the bolts.

[0008] Preferably, both wire ropes are fitted with rubber sleeves on their outer walls.

[0009] Preferably, the ear plate is located between the two U-shaped pieces.

[0010] Preferably, the bottom of the clamp on the steel plate contacts the top of the lower clamp on the steel plate, and the lower clamp on the steel plate and the clamp on the pressing steel plate work together to clamp the steel plate from both the top and bottom sides, thereby achieving self-locking and stable hoisting.

[0011] Preferably, a sling is fixedly connected to the top of the suspended platform, and the top of the sling is sleeved on the outer wall of the hook. The sling flexibly connects the suspended platform and the entire lifting frame to the hook, providing initial suspension stability.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution guides the steel wire rope through pulleys, which drives a structure composed of metal sleeves, I-shaped shafts, and U-shaped parts. Ultimately, it forces the clamps on the steel plate and the lower clamping plate of the steel plate to automatically close, thereby forming multiple evenly distributed clamping points. This overcomes the safety hazards of easy wear and easy cutting caused by direct contact between the rope and the sharp edge of the steel plate in the traditional steel wire rope hoisting method.

[0021] Depend on Figures 1-3 As shown, a steel hoisting device is disclosed, including a hook 1 and a hoisting plate 3. The hook 1 is used for quick connection with large lifting equipment and is the input end of the hoisting force. A sling 16 is fixedly connected to the top of the hoisting plate 3. The top of the sling 16 is sleeved on the outer wall of the hook 1. The sling 16 flexibly connects the hoisting plate 3 and the entire hoisting frame to the hook 1, providing initial suspension stability.

[0022] Two steel wire ropes 2 are fitted on the outer wall of the hook 1. Two grooves are opened on the outer wall of the hanging plate 3. Three shafts 4 are fixedly connected to the inner wall of each of the two grooves. Pulleys 5 are rotatably fitted on the outer wall of each of the six shafts 4. Four of the pulleys 5 are connected in pairs to the outer walls of the two ends of the two steel wire ropes 2. The pulleys 5 can greatly reduce the frictional resistance of the steel wire ropes 2 during turning and sliding, ensuring smooth transmission.

[0023] Two metal sleeves 6 are slidably connected to the outer walls of the two steel wire ropes 2. I-shaped shafts 7 are slidably connected to the inner walls of the four metal sleeves 6. The I-shaped structure of the I-shaped shafts 7 can effectively prevent the metal sleeves 6 from coming off axially. Rubber sleeves 8 are fitted on the outer walls of the two steel wire ropes 2. U-shaped parts 9 are fixedly connected to the outer walls of both ends of the four I-shaped shafts 7. Multiple connecting shafts 10 are fixedly connected between the two U-shaped parts 9. The multiple connecting shafts 10 ensure the integrity and stability of the U-shaped parts 9.

[0024] Two U-shaped parts 9 are fixedly connected by a round shaft 11. The outer walls of the four round shafts 11 are rotatably fitted with steel plate clamps 12. The arc design of the steel plate clamps 12 can fit well with the edge of the steel plate. When under force, they rotate around the round shaft 11 and press the steel plate downward.

[0025] The outer wall of the U-shaped part 9 is provided with a hoisting assembly, which includes four steel plate lower clamping plates 15. The outer wall of each of the eight U-shaped parts 9 has two sliding holes. The inner wall of each sliding hole is slidably connected to the same bolt 13. The outer wall of each of the eight bolts 13 is threaded with a nut. The outer wall of each of the eight bolts 13 is fitted with an ear plate 14. The eight ear plates 14 are fixedly connected to the bottom of the four steel plate lower clamping plates 15 in pairs. The steel plate lower clamping plates 15 and the pressing steel plate clamping plates 12 work together to clamp the steel plates from both the top and bottom, achieving self-locking and stable hoisting. The ear plate 14 is located between two U-shaped parts 9. The bottom of the steel plate clamping plates 12 is in contact with the top of the steel plate lower clamping plates 15.

[0026] Working principle: During use, the hook 1 is connected to the movable end (main rope) of the existing hoisting equipment (tower crane, truck crane, and other professional hoisting equipment). After the existing hoisting equipment is started, the lifting force is transmitted to the two wire ropes 2 through the hook 1. The wire ropes 2 are guided by multiple pulleys 5 on the hoisting plate 3 to transmit the tension downward. The metal sleeve 6, which is slidably connected to the wire ropes 2, moves downward through the frame composed of the I-shaped shaft 7 and the U-shaped part 9. When the entire device descends and the steel plate is placed between the clamp 12 on the steel plate and the lower clamp 15 on the steel plate, the continuous lifting force will force the frame of the U-shaped part 9 to rise as a whole. However, since the steel plate has been clamped, its reaction force will push the lower clamp 15 on the steel plate to close upward relative to the U-shaped part 9 through the bolts 13 and the ear plate 14, thus firmly clamping the two sides of the steel plate together with the clamp 12 on the lowered steel plate. Finally, the steel plate is safely and stably hoisted to the designated position under the combined action of the four symmetrically distributed clamping points.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
