[0031] Please refer to Figure 1 to Figure 4 , an embodiment of the utility model provides a portable disassembly tool, comprising a main rod 1 and a stator holder 2, wherein the stator holder 2 is fixedly mounted on a component to be installed or disassembled;

[0032] A through hole is opened at the top end of the main rod 1 along a direction perpendicular to its axial direction, and a connecting rod 3 is fixedly sleeved in the through hole. The two ends of the connecting rod 3 are detachably fixedly connected to the rotating rod 5 through the first connecting component 4; the bottom end of the main rod 1 is detachably fixedly connected to the clamping sleeve 7 through the second connecting component 6, and the bottom end of the clamping sleeve 7 can be extended into the stator fixture 2 and rotated to clamp therewith; an elastic extrusion component 7 is arranged in the clamping sleeve 7, which is used to squeeze the stator fixture 2 to prevent the clamping sleeve 7 from detaching from the stator fixture 2 after clamping.

[0033] In this embodiment, when installing or removing the expansion-installed component, firstly, the bottom end of the clamping sleeve 7 is inserted into the stator holder 2, and the clamping sleeve 7 is rotated by the rotating rod 5 so that the clamping sleeve 7 is clamped and connected with the stator holder 2. At this time, the worker can hold the rotating rod 5 to press the component into the installation position, or pull the component out of the installation position, which improves the convenience of installing and removing the component.

[0034] When disassembling components, the elastic extrusion assembly 7 squeezes the stator fixer 2 through elastic force, which can prevent the clamping sleeve 7 from being separated from the stator fixer 2 after clamping, thereby improving the reliability of the clamping sleeve 7 and the stator fixer 2 when disassembling components.

[0035] When the disassembly tool of the present application is not in use, the rotary rod 5 can be removed from the connecting rod 3 through the first connecting component 4; the clamping sleeve 7 can be removed from the main rod 1 through the second connecting component 6, which greatly reduces the space occupied by the disassembly tool and is easy to carry.

[0036] In a preferred embodiment, if Figure 2 As shown, the main rod 1, the connecting rod 3 and the rotating rod 5 are all made of steel pipes, with high structural strength, meeting the requirements of disassembly and installation of components.

[0038] In this embodiment, after the equipment has been running for a long time, when the connection between the component and the installation position is too tight due to mud and the component cannot be pulled out by manpower, the hook of the hoist or crane is hung on the lifting ring 92, and the component is lifted and removed with the help of the lifting equipment, which is very practical.

[0039] In a preferred embodiment, if Figure 1 and Figure 2As shown, the first connecting component 4 includes a first connecting column 41 and a first screw 42. One end of the first connecting column 41 can be detachably inserted into the connecting rod 3 and fixedly connected to the connecting rod 3 through the first screw 42.

The bottom end of the second connecting column 61 is provided with a positioning screw hole 63 in a direction perpendicular to its axis. The bottom end of the second connecting column 61 can be detachably inserted into the top end of the clamping sleeve 7 and fixedly connected to the clamping sleeve 7 by the second screw 62.

[0041] In this embodiment, the second screw 62 passes through the clamping sleeve 7 and is threadedly connected to the positioning screw hole 63, thereby fixing the clamping sleeve 7 to the second connecting column 61, realizing a detachable fixed connection of the clamping sleeve 7 while positioning the clamping structure at its bottom, making it convenient for workers to quickly complete the clamping connection between the clamping sleeve 7 and the stator fixer 2 when holding the rotating rod 5.

[0042] In a preferred embodiment, if Figure 4 As shown, the stator holder 2 includes a fixing ring 21, in which a cross 22 is fixedly arranged. The center of the cross 22 is located on the axis of the fixing ring 21 and a positioning hole 23 is provided. The fixing ring 21 is fixed to the component by screws. The installation is convenient and the connection is firm. The cross 22 structure is adopted for the clamping, and the structural strength is high, which meets the requirements of the installation and disassembly of the component.

[0043] In a preferred embodiment, if Figure 2 and Figure 3 As shown, the clamping sleeve 7 includes a main cylinder body 71, the outer diameter of the main cylinder body 71 is smaller than the inner diameter of the fixing ring 21, and the bottom end of the main cylinder body 71 is evenly distributed with four clamping grooves 72 along the circumferential direction, a cross bar 73 is fixedly provided on one side of the bottom end of the clamping groove 72, and an opening 74 is formed between the other side of the bottom end of the clamping groove 72 and the cross bar 73, and an embedding groove 75 is provided on the top of the cross bar 73 away from the opening 74.

After the cross 22 passes through the openings 74 and is inserted into the slots 72, the main cylinder 71 is rotated to make the four rods of the cross 22 respectively inserted into the embedded slots 75, thus completing the clamping connection between the clamping sleeve 7 and the stator holder 2. At this time, the elastic extrusion assembly 8 abuts against the top of the cross 22, ensuring that the cross 22 will not slip out of the embedded slots 75 when lifted, thereby improving the reliability of the clamping connection.

[0045] In a preferred embodiment, if Figure 2 and Figure 3 As shown, the elastic extrusion assembly 8 includes a push rod 81 slidably arranged in the main cylinder body 71, a limiting head 82 is arranged at the top end of the push rod 81, the outer diameter of the limiting head 82 is larger than the outer diameter of the push rod 81, a limiting step is arranged in the main cylinder body 71 corresponding to the limiting head 82, a supporting spring 83 is arranged between the top end of the limiting head 82 and the second connecting assembly 6, and a positioning pin 84 which is fixedly arranged at the bottom end of the push rod 81 and is clearance-matched with the positioning hole 23.

[0046] In this embodiment, after the clamping sleeve 7 and the stator fixture 2 are clamped together, the positioning pin 84 is inserted into the positioning hole 23 to prevent the clamping sleeve 7 and the stator fixture 2 from sliding relative to each other; the bottom end of the push rod 81 abuts against the top of the cross 22 to provide a downward elastic force, which can effectively prevent the clamping sleeve 7 and the stator fixture 2 from detaching after being clamped together, thereby improving the reliability of the clamping connection.
