The oil storage tank 7 is installed on the left and right sides of the top of the U-shaped support three 4. The bottom of one side of the oil storage tank 7 penetrates through the U-shaped support three 4 and is fixedly connected to the oil outlet pipe 701, and the oil outlet pipe 701 penetrates through the I-shaped steel rail 5. There are grooves on the left and right sides of the middle part of the I-shaped steel rail 5, and chutes 702 are opened on both the left and right sides of the grooves. A spring 703 is arranged inside the chute 702. When sliding to the middle of the U-shaped support three 4, the first pulley 10 and the second pulley 12 will contact the slider 704 to make the limit block 705 move upward and compress the spring 703. One side of the spring 703 away from the chute 702 is fixedly connected to the limit block 705. A slider 704 is fixedly connected to the middle position of the limit block 705. One side of the limit block 705 is fixedly connected to a guiding connecting plate 706. The middle part of the top of the guiding connecting plate 706 is fixedly connected to an output rod 707. The bottom inner wall of the oil outlet pipe 701 is rotatably connected to a first rotating shaft 708, and a sealing plate 709 is fixedly connected to the outer wall of the first rotating shaft 708.

[0029] Combined with Figure 6 , it also includes a dust cleaning assembly, which includes a U-shaped connecting plate 8, a fixing plate 801 and a dust shoveling plate 802. The U-shaped connecting plate 8 is arranged at the bottom of the U-shaped support three 4. Fixing plates 801 are fixedly connected to the four sides of the U-shaped connecting plate 8. A dust shoveling plate 802 is fixedly connected to one side of the fixing plate 801 and the dust shoveling plate 802 fits with the track part of the I-shaped steel rail 5. When the U-shaped connecting plate 8 moves, it will drive the fixing plate 801 and the dust shoveling plate 802 to move, and the dust attached to the track part of the I-shaped steel rail 5 is cleaned by the dust shoveling plate 802. Connecting plates two 803 are installed in the middle of the left and right ends of the I-shaped steel rail 5. Fixing plates 801 are fixedly connected to the bottoms of the connecting plates two 803, and a collecting box 804 cooperates with the dust shoveling plate 802. When the dust shoveling plate 802 reaches the collecting box 804, the accumulated dust is sent into the collecting box 804 for collection.

[0030] Combined with Figure 6 and Figure 7, a motor 9 is installed on one side of the U-shaped connecting plate 8. The output end of the motor 9 penetrates through the U-shaped connecting plate 8 and is fixedly connected to a first pulley 10. A second rotating shaft 11 is rotatably connected to the inner wall of the U-shaped connecting plate 8 away from the motor 9. One end of the second rotating shaft 11 away from the U-shaped connecting plate 8 is fixedly connected to a second pulley 12. The first pulley 10 and the second pulley 12 slide within the track of the I-shaped steel rail 5, and the first pulley 10 and the second pulley 12 cooperate with the slider 704 and the guiding connecting plate 706. When the motor 9 is started, the first pulley 10 and the second pulley 12 slide within the I-shaped steel rail 5. When sliding to the middle of the U-shaped support frame three 4, the first pulley 10 and the second pulley 12 will contact the slider 704 and the guiding connecting plate 706.

[0031] Combined with Figure 6 , baffles 13 are installed on the upper parts of the left and right ends of the I-shaped steel rail 5, which can prevent the first pulley 10 and the second pulley 12 from detaching from the I-shaped steel rail 5.

An electric hoist body 14 is installed at the bottom of the lower U-shaped connecting plate 8. The electric hoist can play a role in lifting and transporting heavy objects in a suspension crane or other lifting equipment.

[0033] Working principle: When working, first start the motor 9 to make the first pulley 10 and the second pulley 12 slide within the I-shaped steel rail 5, which can drive the longitudinal movement of the bottom I-shaped steel rail 5 to prepare for the next step.

[0034] Next, when sliding to the middle of the U-shaped support frame three 4, the first pulley 10 and the second pulley 12 will contact the slider 704, causing the limit block 705 to move upward and compress the spring 703. When the slider 704 moves upward, it drives the guiding connecting plate 706 and the output rod 707 to move upward, causing the sealing plate 709 to rotate and tilt. At the same time, the lubricating oil will flow out through the oil outlet pipe 701 and drip on the first pulley 10 and the second pulley 12 for lubrication. When the first pulley 10 and the second pulley 12 pass through the oil outlet pipe 701, the sealing plate 709 will be reset by the resilience of the spring 703 to seal the oil outlet pipe 701. When the sealing plate 709 is opened during the movement of the first pulley 10 and the second pulley 12, the lubricating oil drips on the first pulley 10 and the second pulley 12 to lubricate the first pulley 10 and the second pulley 12, which can effectively reduce the friction between the first pulley 10 and the second pulley 12 and the I-shaped steel rail 5.

[0035] Meanwhile, when the first pulley 10 and the second pulley 12 move, the U-shaped connecting plate 8 will be driven to move, driving the fixed plate 801 and the ash shoveling plate 802 to move. The ash shoveling plate 802 is used to clean the dust adhering to the track part of the I-shaped steel rail 5. When the ash shoveling plate 802 reaches the collection box 804, the accumulated dust is sent into the collection box 804 for collection, so as to clean the accumulated dust on the I-shaped steel rail 5 and avoid the dust from causing obstruction or wear to the first pulley 10 and the second pulley 12.
