[0033] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] In some embodiments, such as Figure 1-4 As shown, this application provides a lifting frame for power plant maintenance, including a base plate 1. A first C-shaped plate 2 is fixed to one side of the upper surface of the base plate 1. A column 3 is rotatably connected inside the first C-shaped plate 2 via a shaft. The top of the side wall of the first C-shaped plate 2 is provided with a plug-in assembly for fixing the column 3. A second C-shaped plate 4 is fixed to the top of the column 3 away from the base plate 1, and the opening of the second C-shaped plate 4 faces downward. A crossbeam 5 is rotatably connected inside the second C-shaped plate 4 via a pin. A support rod 6 is hinged to the lower surface of the crossbeam 5. A sliding sleeve 7 is hinged to the other end of the support rod 6 and is slidably sleeved on the surface of the column 3.

[0035] In some embodiments, a horizontal tube 11 is fixed on the lower surface of the base plate 1 and below the first C-shaped plate 2. Slide rods 12 are slidably connected inside both ends of the horizontal tube 11. An extension rod 13 is fixed at one end of the slide rod 12 outside the horizontal tube 11. The extension rod 13 is perpendicular to the horizontal tube 11.

[0036] In some embodiments, casters are installed on the lower surface of the base plate 1, the lower surface of the slide bar 12 located outside the horizontal tube 11, and the lower surface of the extension bar 13 away from the slide bar 12.

[0037] Specifically, the casters fixed to the lower surfaces of the base plate 1, slide bar 12 and extension bar 13 are of different sizes. It is necessary to ensure that the base plate 1, horizontal tube 11 and extension bar 13 are horizontal, and the casters facilitate the movement of the hanger.

[0038] In some embodiments, the top walls at both ends of the horizontal tube 11 are penetrated and connected by a first locking bolt 14 via a threaded rotation.

[0039] When using this equipment to lift the frame, pull the slide rod 12 out from the horizontal tube 11, and then tighten the first locking bolt 14 to press and fix the slide rod 12. When not in use, push the slide rod 12 back into the horizontal tube 11, so that the two extension rods 13 can be taken into account, thereby reducing the space occupied at the bottom of the frame.

[0040] In some embodiments, the plug-in assembly includes a through hole 21 formed in the side wall of the first C-shaped plate 2, a plug rod 22 is slidably connected inside the through hole 21, an end plate 23 is fixed to one end of the plug rod 22 outside the first C-shaped plate 2, a tension spring 24 is fixedly connected to the end plate 23 and the outer side wall of the first C-shaped plate 2, and a plug hole 31 for inserting the plug rod 22 is formed on the side of the column 3 near the plug rod 22.

[0041] Specifically, the column 3 can rotate within the first C-shaped plate 2, thus allowing it to rotate parallel to the extension rod 13 in a horizontal state, or to rotate to a vertical state, where it will be aligned with the base plate 1. To rotate the column 3 from a horizontal to a vertical state, first pull the end plate 23 to disengage the insertion rod 22 from the first C-shaped plate 2. Then rotate the column 3 until the insertion hole 31 on the column 3 aligns with the insertion rod 22. Next, release the end plate 23, and the tension spring 24 will pull the end plate 23 and the insertion rod 22 back to their original positions, allowing the insertion rod 22 to insert into the insertion hole 31 on the side wall of the column 3, thus fixing the column 3. To rotate the column 3 back to a horizontal state, pull the end plate 23 to disengage the insertion rod 22 from the insertion hole 31, allowing the column 3 to rotate.

[0042] In some embodiments, the sidewall of the sliding sleeve 7 is connected to a second locking bolt 71 via a threaded rotation.

[0043] When the lifting frame needs to be used, slide the sliding sleeve 7 upwards, using the support rod 6 to push the crossbeam 5 to a horizontal position. Then, tighten the second locking bolt 71 to press against the surface of the column 3, thus fixing the sliding sleeve 7. When the lifting frame is not in use, first loosen the second locking bolt 71 so that it no longer presses against the surface of the column 3. Then, slide the sliding sleeve 7 downwards. The sliding sleeve 7 will pull the crossbeam 5 downwards through the support rod 6, bringing the crossbeam 5 closer to the column 3.

[0044] In some embodiments, a lifting assembly is installed on the upper surface of the base plate 1. The lifting assembly includes a motor 8 fixed to the upper surface of the base plate 1, and a wire wheel 9 is fixedly connected to the output shaft of the motor 8. A steel wire 10 is wound on the surface of the wire wheel 9. A plurality of wire loops 51 are fixed to the top of the column 3 and the upper surface of the crossbeam 5. A through hole is opened at the end of the crossbeam 5 away from the column 3. The end of the steel wire 10 away from the wire wheel 9 passes through the plurality of wire loops 51 and the through hole in sequence and is fixedly connected to a hook.

[0045] When lifting equipment is required, the hook on the wire 10 is attached to the equipment, and then the motor 8 is started to drive the reel 9 to rotate. The reel 9 winds up the wire 10, and the wire 10 moves the hook upward, thus lifting the equipment. The wire loop 51 serves to limit and guide the wire 10.

[0046] The operation of this application is as follows: When using the lifting frame of this equipment, first pull the sliding rod 12 out of the horizontal tube 11, then tighten the first locking bolt 14, then pull the end plate 23 to move the insertion rod 22 out of the first C-shaped plate 2, then rotate the column 3 from the horizontal state to the vertical state, then loosen the end plate 23, and the tension spring 24 pulls the end plate 23 and the insertion rod 22 back to their original positions, so that the insertion rod 22 is inserted into the insertion hole 31 on the outer wall of the column 3, thereby fixing the column 3. Next, slide the sliding sleeve 7 upward, use the support rod 6 to support the crossbeam 5, and then tighten the second locking bolt 71 to fix the sliding sleeve 7; when not in use, the crossbeam 5 can be rotated to fit against the column 3, and then the column 3 can be rotated to move closer to the base plate 1, and the sliding rod 12 retracts into the horizontal tube 11, thereby reducing the size of the entire equipment lifting frame, making it easier to store and transport, and the assembly is also very simple and convenient during use.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
