DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1 to Figure 4 In an embodiment of the utility model, a lifting device for construction includes a lifting beam 3, and lifting rings 2 are fixedly installed at the four corners of the top of the lifting beam 3. The lifting ring 2 is connected to the lifting equipment through a sling 1. A clamping plate assembly for clamping a lifting container is installed at the bottom end of the sling 1, and an anti-rotation power assembly connected to the clamping plate assembly is installed at one end of the sling 1. The anti-rotation power assembly is used to drive the clamping plate assembly to clamp or release the lifting container; a warning assembly is vertically slidably connected inside the clamping plate assembly, and the warning assembly is used to prompt the operator whether the clamping plate assembly effectively forms a stable clamp for the lifting container.

[0021] In this embodiment: when transporting a lifting container containing mortar, the entire device is lowered by a lifting equipment until the clamping plate assembly passes over the top protrusion of the lifting container. At this time, the anti-rotation power assembly is started, and the anti-rotation power assembly drives the two parts of the base plate assembly to move toward each other to clamp the lifting container. Thereafter, the lifting equipment drives the entire device to move upward, thereby pulling the lifting container to move. During this process, the lifting container applies an extruding force to the warning assembly, and the warning assembly moves downward and out of the interior of the clamping plate assembly. Therefore, at the beginning of the lifting process, it is possible to quickly determine whether the clamping plate assembly has effectively clamped the lifting container based on whether the warning assembly pops out.

[0022] Please refer to Figure 1 and Figure 2 The clamping plate assembly includes two guide rails 4 fixedly connected to the bottom end of the hanging beam 3, and the two guide rails 4 are symmetrically arranged at the bottom end of the hanging beam 3. The two ends of the sling 1 are fixedly connected with end plates 5 for closing the two ends of the guide rails 4; a clamping plate 6 is arranged below the guide rail 4, and a slider is integrally formed on the top of the clamping plate 6 and is slidably connected to the inner cavity of the guide rail 4. The vertical cross-sections of the inner cavities of the slider and the guide rail 4 are both "convex" shaped structures with a wide top and a narrow bottom;

[0023] A hook plate 7 is fixedly connected to one end of the two clamping plates 6 that are close to each other.

[0024] In this embodiment: when the anti-rotation power assembly is running, the two clamping plates 6 move along the guide rails 4 through the sliders on both sides of the top thereof, so as to adjust the distance between the two clamping plates 6 to adapt to lifting containers of different sizes.

[0025] Please refer to Figure 1 and Figure 2 The anti-rotation power assembly includes a worm 10 installed at one end of the suspension beam 3 through a mounting frame, and the two ends of the worm 10 are rotatably connected to the mounting frame. A forward and reverse motor 9 is installed on the top of the mounting frame, and the output end of the forward and reverse motor 9 is coaxially connected to one end of the worm 10. A worm wheel 11 is meshed with the outer periphery of the worm 10; a guide rod 15 is fixedly connected between the two end plates 5, and a bidirectional stud 12 is rotatably connected between the other two end plates 5, one end of the bidirectional stud 12 passes through the outside of one end plate 5 and is connected to the center of the worm wheel 11, and the bidirectional stud 12 is rotatably connected to the end plate 5 through a bearing.

[0026] In this embodiment: by starting the forward and reverse motor 9, the forward and reverse motor 9 drives the worm 10 to rotate, and the worm 10 drives the worm wheel 11 to rotate during the rotation process, and the rotating worm wheel 11 drives the bidirectional stud 12 to rotate.

[0027] Please refer to Figure 2 The slider on one side of the top of the two splints 6 is slidably connected to the guide rod 15, and the slider on the other side of the top of the two splints 6 is threadedly connected to the bidirectional stud 12. One end of the outer wall of the bidirectional stud 12 is formed with a positive thread 13, and the other end of the outer wall of the bidirectional stud 12 is formed with a reverse thread 14. The connection position of one slider and the positive thread 13 is provided with an internal thread that matches the positive thread 13, and the connection position of the other slider and the reverse thread 14 is provided with an internal thread that matches the reverse thread 14.

[0028] In this embodiment: when the bidirectional stud 12 rotates, the two sliders slide under the action of the internal thread, thereby driving the clamping plate 6 to move, so as to achieve the purpose of clamping the lifting container.

[0029] Please refer to Figure 4The warning component includes a plurality of connecting grooves 16 equidistantly arranged inside the hook plate 7, a spring 17 is connected to the bottom end of the inner wall of the connecting groove 16, and a pressure block 8 is slidably connected to the inner wall of the connecting groove 16 up and down, the pressure block 8 is connected to the top of the spring 17, and the upper half of the pressure block 8 passes through the top of the hook plate 7, and a warning rod 19 is fixedly connected to the bottom end of the pressure block 8, and the bottom end surface of the warning rod 19 in the reset state is parallel to the bottom end surface of the hook plate 7, and a pressure surface 18 is formed on the top surface of the pressure block 8, and the side of the pressure surface 18 close to the clamping plate 6 is a high point, and the side of the pressure surface 18 away from the clamping plate 6 is a low point.

[0030] In this embodiment: during the movement of the two clamping plates 6 towards each other, the two clamping plates 6 drive the inner hook plate 7 to move, and the hook plate 7 is located below the edge protrusion of the lifting container during the movement. When the lifting equipment is lifting (here, the lifting does not mean lifting the lifting container, but is to apply pressure to the pressure block 8, but the lifting container is not directly lifted), the lifting container filled with mortar applies a squeezing force to the pressure block 8, and the pressure block 8 moves downward along the connecting groove 16, and at the same time squeezes the spring 17, and the downwardly moving pressure block 8 drives the warning rod 19 to move down to the bottom of the hook plate 7, which can be seen by the operator;

[0031] If the overall downward movement height of the lifting equipment driving device is insufficient (the hook plate 7 is located below the edge protrusion of the lifting container, but the pressure block 8 is not completely lower than the edge protrusion of the lifting container), the two clamping plates 6 will drive the hook plate 7 to move during the movement of the two clamping plates 6. The hook plate 7 will drive the pressure block 8 to contact the lower edge of the top edge protrusion of the lifting container during the movement, and compression will occur. At this time, the pressure surface 18 will still be forced to drive the pressure block 8 to move downward, so that the warning rod 19 moves to the bottom of the hook plate 7.

[0032] It should be noted that the color of the warning rod 19 is red and can be clearly seen.

[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
