Description

Technical Field

[0001] The utility model relates to the technical field of component lifting frames, in particular to a component lifting frame suitable for double-machine lifting. Background Art

[0002] In the existing construction process, lifting equipment is needed to lift building materials such as prefabricated components of assembled buildings and place the building materials in appropriate positions. This requires a lifting frame that is convenient for lifting building materials to ensure the safety of the lifting process, reduce the number of operating steps, and improve work efficiency.

[0003] A new type of special-shaped component lifting bracket with an overweight alarm is disclosed in the publication number CN207483160U. Although the lifting bracket is equipped with two sensing devices, it provides double safety protection and reduces accidents caused by sensor failure. At the same time, the two sensors can improve the accuracy of overweight prediction.

[0004] However, this new type of special-shaped component lifting frame with an unbalanced weight alarm has the following disadvantages:

[0005] (1) During the lifting of components, due to the different models and specifications of the components, the components occupy too much space, resulting in the inability of the lifting frame to adjust the load range according to the size of the components. At the same time, during the lifting of the two machines, the length of the lifting frame cannot be adjusted according to the position of the two machines;

[0006] (2) During the lifting process, the components are affected by wind, causing the lifting frame to swing, which in turn causes the components to fall off and a safety accident to occur. Utility Model Content

The setting of the top rod 10 improves the bearing capacity and supporting force of the U-shaped chassis 3 because the two ends of the top rod 10 are fixedly connected to the inner wall of the U-shaped chassis 3 respectively.

[0029] See also Figure 1 and Figure 2 The top of the ladder frame 4 is fixedly connected with a rope 11 for lifting, and the top of the rope 11 is provided with a hook 12 for hooking. The setting of the hook 12 is that the hook 12 is fixedly connected to the top of the ladder frame 4 through the rope 11, and the ladder frame 4 is axially symmetrically fixedly connected to the top of the U-shaped base frame 3 on both sides of the square tube 2, thereby facilitating the joint lifting of two machines.

[0031] See also Figure 3 , the top and both sides of one end of the square tube 2 are provided with threaded holes 6 for limiting, and the inside of the threaded holes 6 is provided with screws 7 for fixing. The top and bottom of both ends of the U-shaped chassis 3 are provided with slide grooves 8, and the inside of the slide grooves 8 are slidably connected with the inner top surface and inner bottom surface of the square tube 2. The top surface and side surfaces of both ends of the U-shaped chassis 3 are provided with several threaded holes 9, and the screw 7 threads penetrate the inside of the threaded hole 6 and are connected with the inner threads of the threaded holes 9. During the lifting of the component, when the component is placed on the top of the special-shaped support block 1, the size of the component can be adjusted according to the model and specifications of the component. The telescopic length of the U-shaped chassis 3 on both sides of the square tube 2 can be adjusted. When the component is large, the U-shaped chassis 3 can be pulled to both sides, and the telescopic length can be judged according to the number of exposed threaded holes 9 at the tops and both ends of the U-shaped chassis 3.

During the lifting of the component, when the component is placed on the top of the special-shaped support block 1, the positioning plate 54 can be driven to move to both sides of the component by rotating the threaded bolt 53 until it fits with the surface of the component. As the threaded bolt 53 continues to rotate, the clamping force on both sides of the component can be increased, thereby preventing the component from falling off from the top of the special-shaped support block 1 during lifting, thereby improving the stability and safety of lifting.

When the length is pulled out to the required position, the screw rod 7 can be rotated so that the screw rod 7 thread passes through the inside of the threaded hole 6 until it is threadedly connected with the threaded hole 9, thereby completing the fixation. The positioning plate 54 can be driven to move to both sides of the component by rotating the threaded bolt 53 until it fits with the surface of the component.
