Description

Technical Field

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

[0002] Prefabricated buildings are widely used in the construction industry due to their convenient transportation and simple assembly. The prefabricated components of prefabricated buildings are pre-processed in the factory, then transported to the assembly site, and assembled and installed using hoisting equipment according to certain operating procedures.

[0003] Reference patent (publication number: CN221275069U; publication date: 2024-07-05) discloses a hoisting device for prefabricated building construction, relating to the field of building hoisting technology. It includes a movable base and a hoisting assembly mounted on the movable base for hoisting building materials. The hoisting assembly includes a bracket and a winch fixedly installed on the top of the movable base. A boom is fixedly installed on the top of the bracket, and multiple pulleys are rotatably mounted on the boom. A hoisting rope is slidably mounted on the pulleys. One end of the hoisting rope is fixedly connected to a hook, and the other end of the hook is wound around the winch. A support is installed on the bottom surface of the pulleys, and a stabilizing component is provided on the support. The hoisting rope passes through the stabilizing component.

[0004] Based on the aforementioned patent, the crane activates the lifting mechanism, which includes a motor and a reducer. These components work together to drive the drum to rotate. As the drum rotates, the wire rope begins to wind up, thereby pulling the hook upward. However, existing hooks typically have an open structure at the top, which can easily cause prefabricated components to fall off when affected by swaying winds, resulting in safety accidents. Furthermore, during the hoisting process, the sudden stop or rapid movement of the hoisting rope can generate significant vibration and impact forces, potentially leading to component damage or rope fatigue. Therefore, this utility model provides a hoisting device for prefabricated building construction. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hoisting device for prefabricated building construction. It solves the problems that existing hooks, which are usually open at the top, are prone to causing prefabricated components to fall off when subjected to swaying or wind, resulting in safety accidents. It also addresses the issue that during hoisting, the sudden stop or rapid movement of the hoisting rope can generate significant vibration and impact, potentially leading to component damage or rope fatigue.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for prefabricated building construction, comprising a load-bearing base, wherein a hoisting mechanism for prefabricated building construction is provided on the load-bearing base, and the hoisting mechanism includes:

[0007] The shock absorption assembly includes a frame fixed to the upper surface of a load-bearing base, a lifting frame rotatably connected to the front end of the frame via a rotating shaft, a lifting rope for lifting at the top of the lifting frame, and a connecting shell connected to the lower end of the lifting rope via a buffer assembly.

[0008] The anti-detachment component includes a hanging body fixed at the lower end of the connecting shell, a connecting shaft fixed to the top outer wall of the hanging body, a locking rod rotatably connected to the outer wall of the connecting shaft, and groove blocks for engaging the locking rod fixed to the two side walls of the hanging body.

[0009] Preferably, the front end of the frame is provided with a first hydraulic rod rotatably connected via a rotating shaft, the telescopic end of the first hydraulic rod is rotatably connected to the lifting frame via the rotating shaft, a second hydraulic rod is provided below the first hydraulic rod, the base of the second hydraulic rod is rotatably connected to the frame via a rotating shaft, and the telescopic extension of the second hydraulic rod is rotatably connected to the lifting frame via the rotating shaft.

[0010] Preferably, the buffer assembly includes a connecting block fixed to the end of the lifting rope, a fixing plate fixed to the lower end of the connecting block, a shock-absorbing spring fixed to the upper surface of the fixing plate, and the connecting shell fixedly connected to one end of the shock-absorbing spring.

[0011] Preferably, the inner ring of the shock-absorbing spring is provided with a damping support rod, and the lower end of the damping support rod is fixedly connected to the fixing plate.

[0012] Preferably, a slide rail housing is fixed to the side wall of the groove block, and a connecting rod is slidably connected inside the slide rail housing.

[0013] Preferably, the connecting rod has a bolt extending from its interior to the outside of the slide rail housing, and the connecting rod has a threaded hole located to the left of the bolt. A locking bracket is fixed to the inner wall of the connecting rod.

[0014] Beneficial effects

[0015] This utility model provides a hoisting device for prefabricated building construction. Compared with the prior art, it has the following advantages:

[0016] Firstly, after the hoisting body hooks and lifts the object, the locking rod is rotated on the hoisting body via the connecting shaft, causing one end of the locking rod to engage with the groove block. Then, the bolt is removed, and the locking bracket is inserted into the slide rail housing via the connecting rod. The bolt is then locked into the threaded hole, so that the L-shaped locking rods on both sides of the locking bracket are in contact with the upper end face of the locking rod, thereby closing the top of the hoisting body after the object is hoisted. This effectively avoids the risk of the hoisted object falling off during the hoisting process, reduces the risk of damage or falling of the object due to unstable hoisting, significantly improves the safety of hoisting operations, and reduces the occurrence of accidents.

[0017] Secondly, the main body of this utility model is subjected to downward pressure through the connecting shell. Then, the connecting shell, through the shock-absorbing spring and the damping support rod, provides a certain shock absorption and buffering effect on the fixed plate, thereby providing shock absorption and buffering for the lifting rope on the fixed plate through the connecting block. Firstly, the shock-absorbing spring absorbs the instantaneous impact force generated during the lifting process through elastic deformation, while the damping support rod further consumes the vibration energy through friction or fluid resistance. The instantaneous tension fluctuation of the lifting rope reduces the risk of rope breakage and ensures the continuity of the lifting operation. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a hoisting device for prefabricated building construction, including a load-bearing base 1, on which a hoisting mechanism for prefabricated building construction is provided, the hoisting mechanism including:

[0025] The shock absorption assembly includes a frame 2 fixed to the upper surface of the load-bearing base 1, a lifting frame 201 rotatably connected to the front end of the frame 2 via a rotating shaft, a lifting rope 204 for lifting is provided at the top of the lifting frame 201, and a connecting shell 4 connected via a buffer assembly is provided at the lower end of the lifting rope 204.

[0026] The anti-detachment component includes a hanging body 5 fixed to the lower end of the connecting housing 4, a connecting shaft 501 fixed to the top outer wall of the hanging body 5, a locking rod 502 rotatably connected to the outer wall of the connecting shaft 501, and groove blocks 6 fixed to the two side walls of the hanging body 5 for engaging the locking rod 502.

[0027] In a preferred embodiment, a first hydraulic rod 202 is rotatably connected to the front end of the frame 2 via a rotating shaft. The telescopic end of the first hydraulic rod 202 is rotatably connected to the lifting frame 201 via the rotating shaft. A second hydraulic rod 203 is located below the first hydraulic rod 202. The base of the second hydraulic rod 203 is rotatably connected to the frame 2 via a rotating shaft. The telescopic extension of the second hydraulic rod 203 is rotatably connected to the lifting frame 201 via the rotating shaft. When the first hydraulic rod 202 and the second hydraulic rod 203 extend or retract, they simultaneously push the lifting frame 201, enabling the lifting frame 201 to be angled on the frame 2 via the rotating shaft. This controls the position adjustment of the hanging body 5 on the lifting frame 201 via the lifting rope 204, allowing the hanging body 5 to quickly reach the designated position. This can adapt to the lifting needs of components of different shapes and sizes, improving the versatility and adaptability of the device. The simultaneous action of the first hydraulic rod 202 and the second hydraulic rod 203 provides stable support for the lifting frame 201.

[0028] In a preferred embodiment, the buffer assembly includes a connecting block 3 fixed to the end of the lifting rope 204, a fixing plate 301 fixed to the lower end of the connecting block 3, a shock-absorbing spring 302 fixed to the upper surface of the fixing plate 301, a connecting shell 4 fixedly connected to one end of the shock-absorbing spring 302, a damping support rod 303 provided in the inner ring of the shock-absorbing spring 302, and the lower end of the damping support rod 303 fixedly connected to the fixing plate 301. When the suspended body 5 lifts the prefabricated building component, the suspended body 5 is subjected to force through the connecting shell 4. The pressure is absorbed by the outer shell 4, which, through the shock-absorbing spring 302 and the damping support rod 303, provides a certain degree of shock absorption and buffering on the fixed plate 301. This provides shock absorption and buffering for the lifting rope 204 on the fixed plate 301 via the connecting block 3. Firstly, the shock-absorbing spring 302 absorbs the instantaneous impact force generated during the lifting process through elastic deformation, while the damping support rod 303 further consumes the vibration energy through friction or fluid resistance. The instantaneous tension fluctuation of the lifting rope 204 reduces the risk of rope breakage and ensures the continuity of the lifting operation.

[0029] In a preferred embodiment, a slide rail housing 601 is fixed to the side wall of the groove block 6. A connecting rod 602 is slidably connected inside the slide rail housing 601. A bolt 604 is provided inside the connecting rod 602 extending to the outside of the slide rail housing 601. A threaded hole 603 is provided inside the connecting rod 602, located to the left of the bolt 604. A locking bracket 605 is fixed to the inner wall of the connecting rod 602. After the hanging body 5 hooks and lifts the object, the locking rod 502 is rotated on the hanging body 5 via the connecting shaft 501, so that one side of the locking rod 502... The end engages with the groove block 6, then the bolt 604 is removed, and the locking bracket 605 is inserted into the slide rail housing 601 through the connecting rod 602. The bolt 604 is locked into the threaded hole 603, so that the L-shaped locking rods on both sides of the locking bracket 605 are in contact with the upper end face of the locking rod 502, thereby closing the upper part of the hanging body 5 after the object is hoisted. This effectively avoids the risk of the hoisted object falling off during the hoisting process, reduces the damage or falling accident caused by unstable hoisting, significantly improves the safety of hoisting operations, and reduces the occurrence of accidents.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] During operation, the first hydraulic rod 202 and the second hydraulic rod 203 extend and retract, simultaneously pushing the lifting frame 201. This allows the lifting frame 201 to be angled on the frame 2 via a rotating shaft, controlling the position of the hanging body 5 on the lifting frame 201 via the lifting rope 204. When lifting prefabricated building components, the hanging body 5 is subjected to downward pressure through the connecting shell 4. The connecting shell 4 then provides shock absorption and buffering on the fixed plate 301 via the shock-absorbing spring 302 and the damping support rod 303, thereby providing shock absorption and buffering on the lifting rope 204 on the fixed plate 301 via the connecting block 3. The shock-absorbing spring 302 absorbs the instantaneous impact force generated during the lifting process through elastic deformation.

[0032] After the hanging body 5 hooks and lifts the object, the locking rod 502 is rotated on the hanging body 5 via the connecting shaft 501, so that one end of the locking rod 502 engages with the groove block 6. Then, the bolt 604 is removed, and the locking bracket 605 is inserted into the slide rail housing 601 via the connecting rod 602. The bolt 604 is locked and installed with the threaded hole 603, so that the L-shaped locking rods on both sides of the locking bracket 605 are in contact with the upper end face of the locking rod 502, thereby closing the top of the hanging body 5 after the object is lifted, effectively avoiding the risk of the lifted object falling off during the lifting process.
