[0024] The present invention will be further described below with reference to the accompanying drawings. The structure and principle of the present invention will be very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0025] As shown in Figures 7-8, the utility model discloses a floating plate jacking equipment quick fixing sleeve 1 device, including a bottom plate 2-1, a top plate 2-3 and a rib plate 2-2, and the entire device is made of alloy steel.

[0026] As shown in Figure 1-6, the bottom plate is shaped like the hole 1-2 of the outer sleeve 1, and the middle part is a groove structure, which is convenient for clamping the hole wall at the hole 1-2 of the outer sleeve 1. This method can achieve quick connection with the outer sleeve 1, avoiding the traditional connection method of using bolts and the threaded hole 1-1 of the outer sleeve 1.

[0027] The base plate 2-1 includes a two-layer structure of an upper base plate and a lower base plate. The upper base plate and the lower base plate are connected by a connecting plate. The outer diameter of the connecting plate is smaller than the outer diameters of the upper base plate and the lower base plate, so that a groove structure is formed between the connecting plate and the upper base plate and the lower base plate.

[0028] The upper base plate and the lower base plate have the same shape and are arranged parallel to each other. The shapes of the upper base plate and the lower base plate match the shape of the top opening of the outer sleeve 1. A number of limit blocks are provided on the surrounding sides. A jacking device is provided on the top of the upper base plate. One end of the jacking device is connected to the top plate 2-3. The shape of the lower base plate matches the shape of the top opening of the outer sleeve 1. After the lower bottom passes through the top opening of the outer sleeve 1, it rotates so that the limit blocks of the upper base plate and the lower base plate jointly limit the top of the outer sleeve 1.

[0029] The upper base plate and the lower base plate are connected by a connecting plate, the outer diameter of which is smaller than the outer diameters of the upper base plate and the lower base plate, so that a groove structure is formed between the connecting plate and the upper base plate and the lower base plate.

[0030] Top plate 2-3 is used to connect the lifting equipment.

[0031] The rib plate 2-2 is a hollow structure, disposed between the bottom plate 2-1 and the top plate 2-3, and is used to connect the bottom plate and the top plate 2-3.

[0032] The method for using the quick fixing sleeve device of the floating plate jacking equipment of the utility model is as follows:

[0033] Step 1: Align the bottom plate 2-1 with the hole wall at the hole 1-2 of the outer sleeve 1;

[0034] Step 2: Lower the bottom plate 2-1 so that the groove is aligned with the hole wall, then rotate the quick-fix sleeve device 2 so that the bottom plate 2-1 is stuck to the hole wall at the hole 1-2 of the outer sleeve 1;

[0035] Step 3: Start lifting;

[0036] Step 4: After the lifting is completed, rotate the quick fixing sleeve device 2 to lift out the bottom plate 2-1;

[0037] Repeat the above steps to proceed to the next task.

[0038] The above description is only a specific implementation method of this utility model, but the protection scope of this utility model is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by this utility model, can make equivalent substitutions or changes based on the technical solutions and new concepts of this utility model, which should be covered by the protection scope of this utility model.
