A transverse lead screw is provided near the top of the movable frame, and the middle part of the lead screw is threaded, and the middle part of the lead screw is threadedly connected to two nuts, and the two nuts are respectively fixedly connected to the corresponding movable frame, and the two ends of the lead screw are both rotatably and slidably connected to the corresponding movable frame. The axis of rotation of the clamping plate passes through the center of gravity of the casing, and the casing is very labor-saving when adjusting the pitch angle by rotation. Therefore, by using the present invention to install the casing, it is not only time-saving and labor-saving, but also very convenient to adjust the angle of the casing, and the casing is not easy to shake during adjustment, so it is not easy to bump, avoiding squeezing and colliding the operator.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the existing lifting device, the structure of clamping the capacitor sleeve uses threaded cooperation to rotate to displace the capacitor sleeve, so that a large number of rotations are required, resulting in low operating efficiency, and it does not have the function of rotating to adjust the angle, resulting in inefficiency and simplicity when transferring the capacitor sleeve. Utility Model Content

[0005] The utility model aims to solve the technical problems that the existing lifting device has a structure for clamping the capacitor sleeve, which uses threaded cooperation to rotate to displace the capacitor sleeve, so that many circles of rotation are required, resulting in low operating efficiency, and the device does not have the function of rotating to adjust the angle, resulting in insufficient efficiency and simplicity when transferring the capacitor sleeve. A capacitor sleeve lifting and rotating device is provided.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model describes a capacitor bushing lifting and rotating device, comprising a lifting frame; symmetrical openings on the lifting frame are used to insert lifting rods; the lower end of the lifting rod is fixedly connected to upper and lower movable plates; the upper and lower movable plates are pin-connected with a rotating movable plate; a first oil cylinder is fixedly connected to openings corresponding to the upper and lower movable plates in the lifting frame; a movable block is connected to a slotted pin on the rotating movable plate; a second oil cylinder is fixedly connected to openings corresponding to the movable blocks on the upper and lower movable plates; one end of the rotating movable plate is fixedly connected to a fixed end plate; the fixed end plate is fixedly connected to a first plug shaft; the other end of the rotating movable plate is slidably sleeved with a movable end plate; and the movable end plate is fixedly connected to a second plug shaft.

[0008] Furthermore, a second rotating sleeve is rotatably connected to the second plug shaft; and a first rotating sleeve is rotatably connected to the first plug shaft.

[0009] Furthermore, the corresponding movable end plate on the rotating movable plate is detachably fixed to a limiting plate.

[0010] Furthermore, a plurality of universal wheels are fixedly connected to the lower surface of the hanging frame.

[0011] Furthermore, a counterweight plate is placed on the upper surface of the hanging frame.

[0012] The utility model provides a capacitor bushing hoisting and rotating device, which has the following beneficial effects:

[0013] 1. The utility model uses a first oil cylinder to push the upper and lower movable plates and the rotating movable plate down to the height of the axis of the insulating sleeve, and then the fixed first plug shaft and the movable second plug shaft are displaced to insert the openings at both ends of the insulating sleeves of different lengths, and then the first oil cylinder is reset to pull the insulating sleeve to be suspended in the air, and then the insulating sleeve can be pushed to rotate and change its own angle, and then the second oil cylinder pushes the movable block downward, and the movable block pushes the rotating movable plate to rotate, and the rotating movable plate rotates from a horizontal state to a vertical state, thereby changing the insulating sleeve fixed under the rotating movable plate from a horizontal state to a vertical state, so that the angle in the vertical direction can also be changed, solving the problem that the existing hoisting device is difficult to adjust the axis direction angle and the rotation angle in space;

[0014] 2. When the utility model replaces the first plug shaft and the second plug shaft with the first rotating sleeve and the second rotating sleeve to contact the openings at both ends of the insulating sleeve, the insulating sleeve can be rotated to adjust the angle in a horizontally suspended state, so as to facilitate the installation of the remaining parts. At the same time, when the insulating sleeve is in a vertical state, the angle of the insulating sleeve can also be changed by rotating the first rotating sleeve, thereby realizing the function of adjusting the angle for auxiliary installation in both horizontal and vertical states, solving the problem that the existing lifting device is difficult to rotate horizontally and vertically to turn the capacitor sleeve.

Then the first oil cylinder 5 is reset to pull the insulating sleeve into the air, and then the insulating sleeve can be pushed to rotate and change its own angle. Then the second oil cylinder 7 pushes the movable block 6 downward, and the movable block 6 pushes the rotating movable plate 4 to rotate, and the rotating movable plate 4 rotates from a horizontal state to a vertical state, thereby changing the insulating sleeve fixed under the rotating movable plate 4 from a horizontal state to a vertical state, so that the angle in the vertical direction can also be changed, which solves the problem that the existing lifting device is difficult to adjust the axial direction angle and the rotation angle in space.

[0024] A second rotating sleeve 14 is rotatably sleeved on the second plug shaft 13; a first rotating sleeve 10 is rotatably sleeved on the first plug shaft 9; when working, the first rotating sleeve 10 and the second rotating sleeve 14 replace the first plug shaft 9 and the second plug shaft 13 to contact the openings at both ends of the insulating sleeve, so that the insulating sleeve can be rotated to adjust the angle in a horizontal suspended state, so as to adjust the angle for convenient installation of remaining parts, and at the same time, in the vertical state of the insulating sleeve, the angle of the insulating sleeve can also be changed by rotating the first rotating sleeve 10, so as to realize the function of adjusting the angle for auxiliary installation in both horizontal and vertical states, which solves the problem that the existing lifting device is difficult to rotate horizontally and vertically to turn the capacitor sleeve.

The angle can be adjusted by rotation, so that the angle can be adjusted to facilitate the installation of the remaining parts. At the same time, when the insulating sleeve is in a vertical state, the angle of the insulating sleeve can also be changed by rotating the first rotating sleeve 10, so as to realize the function of adjusting the angle for auxiliary installation in both horizontal and vertical states, solving the problem that the existing lifting device is difficult to rotate horizontally and vertically to turn the capacitor sleeve; the limit plate 12 prevents the movable end plate 11 from detaching from the rotating movable plate 4 to cause danger, making it safer when used; the universal wheel 15 makes it more convenient and safer to move the lifting frame 1 to adjust the angle of the capacitor sleeve, so that the rotation angle and position of the capacitor sleeve can be accurately adjusted, solving the problem that the existing lifting structure cannot rotate the angle of the capacitor sleeve; the counterweight plate 16 can stably operate to change the angle of the capacitor sleeve when lifting and rotating the capacitor sleeve with large size and weight, thereby ensuring that the center of gravity is located within the vertical area of ​​the lifting frame 1, so that there is no risk of tipping, making it safer when used.
