[0002] In the field of steel structure engineering, the lifting of plates has always been an important part of the construction process. However, due to the large size and heavy weight of steel structure plates, there are many difficulties in the lifting process. When lifting steel structure plates, traditional steel plate lifting is often difficult to stably fix the plates, which not only affects the construction progress, but also may pose a threat to the safety of the construction site. Especially when working at high altitudes, if the plates slip or shake during the lifting process, the consequences will be disastrous.

[0003] In addition, traditional lifting devices often lack flexibility and convenience during operation, which requires workers to spend a lot of time and energy to debug and fix the equipment when lifting plates. This not only reduces work efficiency, but also increases the labor intensity of workers. Therefore, in view of the problems existing in the existing steel plate lifting tooling when lifting steel structure plates, it is urgent to develop a new, efficient and safe steel structure plate lifting device to improve construction efficiency and ensure construction safety.

[0009] Preferably, the base body support groove is a U-shaped groove with a round hole on the top for installing the pressing plate and the lifting column.

[0010] Preferably, a serrated groove is provided on the upper side of the bottom of the base body support groove and on the lower side of the bottom of the pressing clamp plate to increase the friction force of the clamp formed by the two.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a steel structure plate lifting device, such as Figure 1-Figure 4 As shown, it includes a base main body support groove 1, a downward pressing splint 2 is arranged on the inner side of the base main body support groove 1, a lifting column 21 is installed on the top of the downward pressing splint 2, the top of the lifting column 21 passes through the base main body support groove 1 and is installed with a large fixed pulley 5, a steel rope 6 is installed on the top of the base main body support groove 1, the base main body support groove 1 is clamped on the steel structure plate, the base main body support groove 1 is pulled up by the steel rope 6, and the plate is clamped by the downward pressing splint 2 to achieve rapid lifting.

[0024] In this embodiment, a lifting ring is installed on the top of the steel rope 6, and the top end of the steel rope 6 is connected to the crane through a shoulder beam.

[0025] Specifically, a spring 3 is installed between the pressing clamp plate 2 and the upper inner wall of the base body supporting groove 1. The spring 3 is sleeved on the outer side of the lifting column 21, so that the clamp formed by the spring 3 has retractability.

[0026] Furthermore, two small fixed pulleys 4 are installed on the top surface of the base body support groove 1, and the steel rope 6 passes through the bottom of one small fixed pulley 4 in turn, passes through the upper part of the large fixed pulley 5, and then passes out from the bottom of the other small fixed pulley 4, and both ends of the steel rope 6 are connected to the lifting ring, so as to achieve the purpose of clamping the clamp composed of the base body support groove 1 and the downward pressure clamp 2 when lifting upward, and at the same time ensure that the purpose of tightening the plate can be achieved when lifting in all directions.

[0027] Furthermore, the base body support groove 1 is a U-shaped groove with a round hole on the top for installing the pressing clamp 2 and the lifting column 21.

[0028] Furthermore, serrated grooves are provided on the upper side of the bottom of the base body support groove 1 and on the lower side of the bottom of the pressing clamp 2 to increase the friction of the clamp formed by the two to ensure tight clamping without sliding.

[0029] Furthermore, the outer ring surfaces of the large fixed pulley 5 and the small fixed pulley 4 are both provided with inwardly recessed grooves to ensure that the steel rope 6 is limited and does not slip off.

[0030] Furthermore, the small fixed pulleys 4 are symmetrically arranged on both sides of the lifting column 21 to ensure that the base body support groove 1 is horizontally stable and does not tilt when lifting.

[0031] It is worth noting that the large fixed pulley 5 and the small fixed pulley 4 can be equipped with additional pulleys to form a more labor-saving pulley group, which is convenient for lifting heavier steel structure plates more stably.

[0032] When using the steel structure plate lifting device of the utility model, an appropriate number of steel structure plate lifting devices are selected according to actual needs. Two or four steel structure plate lifting devices are connected to the crane through steel ropes 6 and lifting rings, and the base body support groove 1 is placed on the steel structure plate to ensure stable clamping. The pressing clamp plate 2 cooperates with the base body support groove 1 under the action of the spring 3 to form a clamping force to clamp the plate tightly. The serrated groove enhances the stability of clamping.

[0033] Operate the crane to lift the device upwards through the steel rope 6. As the steel rope 6 is tightened, the downward pressure on the clamping plate 2 is further increased to increase the clamping force on the plate. The large fixed pulley 5 and the small fixed pulley 4 change the direction of the steel rope 6 to ensure stability and stability during the lifting process. After the plate is lifted to the desired position, slowly lower the height of the crane to accurately place the plate at the target position. Release the tension of the crane to reduce the pressure of the steel rope 6 on the clamping plate 2, thereby reducing the clamping force on the plate, and then disconnect the steel rope 6 from the crane, remove the device from the plate, and prepare for the next operation.
