Description

Technical Field

[0002] At present, prefabricated buildings have been widely promoted and applied. As an important integral flexural member in prefabricated buildings, laminated slabs are crucial for the development of building industrialization. During the construction of high-rise laminated slabs, four steel hooks are usually installed by a tower crane, and the steel hooks are hooked on the truss bars of the laminated slab, and the laminated slab is hoisted from the ground to the floor working surface. However, the position of the steel hook cannot be adjusted, and it cannot meet the lifting position requirements of precast laminated slabs with different sizes and specifications. Subsequently, such as in patent CN202311661649.3, a laminated slab hoisting structure, there are multiple installation positions on the lifting crossbeam. By changing the hoisting positions corresponding to different quick-release connection components, the included angle between the quick-release connection component and the lifting foundation (i.e., the laminated slab) can be changed. However, multiple installation positions need to be arranged, and the position adjustment between two installation positions cannot be adapted, weakening the adaptability.

[0003] Therefore, there is an urgent need for a laminated slab hoisting device with a simple structure and reasonable design. By adjusting the anti-detachment part upwards, the sliding adjustment of the hoisting block along the length direction of the hoisting frame is realized, and the upper adjustment anti-detachment part cooperates with the support locking part to realize the limit locking after the hoisting block slides to the adjusted position, so that the hook of the hoisting hoist under the hoisting block can meet the hoisting requirements of laminated slabs with different specifications and lengths, and the hoisting safety is improved.

[0046] In this embodiment, an inclination sensor 6-13 is provided on the top of the upper limit block 6-11.

[0047] In this embodiment, during actual use, the upper limit block 6-11 and the lower limit support block 6-12 are arranged to form the top support limit block 6-1.

[0051] In this embodiment, the horizontal screw rod 7-1 is provided, which is not only convenient for the penetration of the lifting block 6-4 and further assists in supporting the lifting block 6-4, but also can be locked by the locking nut 7-2 after the lifting block 6-4 is adjusted in place, improving the stability when the hoist 6-5 at the bottom of the lifting block 6-4 hoists the laminated board subsequently.

[0052] In this embodiment, four lifting lugs 1-3 are provided to connect the laminated board hoisting device to the hoisting machine through them, so that the hoisting machine can be operated to hook and hoist through this hoisting device and hoist the laminated board to a predetermined height; the auxiliary lifting holes 1-4 are provided. During actual use, a relief groove is opened at the position of the upper limit block 6-11 close to the auxiliary lifting holes 1-4, so that during hoisting, a hoisting steel wire rope can also be penetrated through the auxiliary lifting holes 1-4 to be connected to the hoisting machine, thereby cooperating with the four lifting lugs for hoisting and assisting in improving the safety.

[0053] In this embodiment, the second support limiting plate 3 is a convex plate, which is to extend into the space between the two longitudinal frame rods 1-1 at the top for fixed connection, and the step surface is attached to the bottom surface of the longitudinal frame rod 1-1 for connection.

[0054] In this embodiment, a hoisting winch 6-5 is provided, which can not only meet the requirement that the hook is hooked on the laminated board to connect the laminated board, but also, when the laminated board descends after being hoisted, operate the hoisting winch 6-5 to finely adjust the laminated board, so that the laminated board is horizontally placed as a whole at the required position, improving the convenience.

[0055] In this embodiment, the hoisting winch 6-5 can refer to a manual winch or an electric winch.

[0056] In this embodiment, the first support limiting plate 2, the second support limiting plate 3 and the third support limiting plate 4 are provided to realize the installation of the horizontal screw rod 7-1 and the limiting support of the lifting block 6-4.

[0057] In this embodiment, an inclination sensor 6-13 is provided, which can refer to the inclination sensors commonly disclosed in the art or other inclination sensors that can meet the requirements, to detect the top surface inclination of the upper limiting block 6-11 during hoisting, and avoid the insecurity caused by the inclination of the laminated board hoisting device.

[0058] When the utility model is specifically used, loosen the locking nut 7-2 to disengage from the lifting block 6-4 to release the locking, and respectively adjust the first hoisting mechanism 5 and the second hoisting mechanism 6 to move left and right at both ends along the length direction of the lifting frame 1 according to the length specification of the laminated board to be hoisted, so as to adjust the distance between the first hoisting mechanism 5 and the second hoisting mechanism 6 to meet the hoisting requirements of the laminated board, and then screw the locking nut 7-2 to tightly contact the lifting block 6-4 for locking;

[0059] Then connect the hook of the hoisting winch 6-5 to the truss hook on the laminated board, then use a hoisting machine to hook and hoist the four lifting lugs 1-3 through a steel wire rope and hoist the laminated board to a predetermined height, and then the hoisting machine lowers the laminated board. During the lowering process of the laminated board, if the laminated board is not flat, the construction personnel can further operate the hoisting winch 6-5 to finely adjust the laminated board, so that the laminated board is horizontally placed as a whole at the required position, and disconnect the connection between the hook of the hoisting winch 6-5 and the truss hook on the laminated board, which is convenient for hoisting the next laminated board.

[0060] To sum up, the utility model has a simple structure and a reasonable design. The upper adjusting anti-detachment part is used to realize the sliding adjustment of the lifting block along the length direction of the lifting frame, and the upper adjusting anti-detachment part cooperates with the support locking part to realize the limiting locking after the sliding adjustment of the lifting block in place, so that the hook of the hoisting winch under the lifting block can adapt to the hoisting requirements of laminated boards with different specifications and lengths, and improve the hoisting safety.

[0061] The above are only the preferred embodiments of the present utility model, and do not impose any restrictions on the present utility model.
