Description

Technical Field

[0001] The present application relates to the technical field of lifting devices, and more specifically, to a lifting device for assembled buildings. Background Art

[0002] Reinforced concrete panels are processed in prefabrication plants or construction sites for building assembly, referred to as wall panels or sidings. Using prefabricated concrete wall panels to build assembled large-panel buildings can improve the degree of factory-based and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction period.

[0003] The document with prior art publication number CN216129243U provides an auxiliary lifting machine for wall panels for prefabricated buildings. By rotating the support plate connected to the right side of the lifting plate, the lifting machine can select the direction in which the lifting plate is placed to lift the wall panels according to the on-site construction requirements, thereby making it more convenient for construction workers to install wall panels when using the lifting machine, which is beneficial to improving the work efficiency of construction workers.

[0004] Although the device has many beneficial effects, the following problems still exist: when lifting the wall panels, it is difficult to quickly fix the wall panels, resulting in the wall panels falling due to the large shaking amplitude during the lifting process, which easily reduces the device's ability to prevent safety accidents. In view of this, we propose a lifting device for prefabricated buildings. Utility Model Content

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 and Figure 2 , the embodiment of the present application discloses a lifting device for an assembled building. The lifting device for an assembled building comprises: a bottom plate 1;

[0026] A support frame 2 is fixedly connected to the top of the bottom plate 1, a suspension rod 4 is fixedly connected to the top of the support frame 2, and positioning mechanisms 3 are provided on both sides of the top of the bottom plate 1 for positioning the wall panel;

[0027] The positioning mechanism 3 includes a mounting plate 31, which is located at the top of the base plate 1. A fixing plate 33 is fixedly connected to one side of the mounting plate 31. The fixing plate 33 is slidably connected to the top of the base plate 1. Connecting plates 34 are fixedly connected to both sides of the top of the base plate 1. A threaded groove is penetrated through one side of the connecting plate 34. A threaded rod 36 is threadedly connected in the threaded groove. One end of the threaded rod 36 is rotatably connected to the fixing plate 33, thereby facilitating the fixing of the wall panel and preventing the wall panel from falling off.

[0028] Reference Figure 1 and Figure 2 A pad 35 is fixedly connected to the inner side of the mounting plate 31. The pad 35 is made of rubber material, which is convenient for protecting the wall panel.

[0029] Reference Figure 1 and Figure 2 The cross-sections of the backing plate 35 and the mounting plate 31 are both L-shaped, so as to facilitate clamping the corners of the wall panel.

[0030] Reference Figure 1 and Figure 2 Slide grooves are provided on both sides of the top of the bottom plate 1, and a slider 32 is slidably connected in the slide groove. The top of the slider 32 is fixedly connected to the bottom of the fixed plate 33, so that the fixed plate 33 can move along the direction of the slide groove.

[0031] Reference Figure 1 The slide groove is inclined and the two slide grooves are diagonally arranged, so that it is convenient to clamp and fix the two diagonally opposite corners of the wall panel to prevent the wall panel from falling off.

[0032] Reference Figure 2 A transverse plate 37 is fixedly connected to the top of the inner wall of the pad 35, and a pressure plate 38 is fixedly connected to the bottom of the transverse plate 37 through a spring 39, so as to facilitate the fixing of wall panels of different thicknesses.

[0033] Reference Figure 2 A slide bar 5 is slidably connected to the top of the horizontal plate 37, and a pull plate 6 is fixedly connected to the top of the slide bar 5, so that the staff can pull the pressure plate 38 to move upward.

[0034] Reference Figure 1 and Figure 2 A groove is provided on one side of the fixing plate 33, a bearing is installed in the groove, and one end of the threaded rod 36 is located in the bearing, so as to reduce the friction when the threaded rod 36 rotates.

[0035] The implementation principle of a lifting device for prefabricated buildings in an embodiment of the present application is as follows: when the wall panel needs to be hoisted, the staff can place the wall panel on the top of the base plate 1, and then pull the sliding rod 5 to drive the pressure plate 38 to move up and squeeze the spring 39, and then screw the threaded rod 36 to drive the fixed plate 33 to move. The movement of the fixed plate 33 can drive the movement of the mounting plate 31, and the movement of the mounting plate 31 can drive the pad 35 to move, so that the pad 35 can be clamped and fixed with the corners of the wall panel. When the pad 35 contacts the corners of the wall panel, release the sliding rod 5, so that the squeezed spring 39 rebounds and drives the pressure plate 38 to move up and clamp and fix the top of the wall panel, and then hoist the wall panel through an external crane connected to the hoisting rod 4 to prevent the wall panel from detaching during hoisting.

[0036] The embodiment of the present application provides a lifting device for prefabricated buildings. By setting a positioning mechanism 3, it is convenient for workers to clamp and fix the two corners of the wall panel to prevent the wall panel from falling off due to large shaking during the lifting process, thereby facilitating improving the device's ability to prevent safety accidents.
