[0032] As Figures 1-8 shown, the present invention provides a technical solution: specifically including:

[0033] A crankshaft 1, a connecting journal 6 and a crank portion 4 are installed outside the crankshaft 1, a connecting handle 11 is installed inside the crank portion 4, and a piston cylinder 12 is installed on the top of the connecting handle 11, and a piston head 13 is installed inside the piston cylinder 12;

[0034] The crankshaft with a crank portion further includes:

[0035] A piston assembly 5, used to connect the piston head 13 and control the movement of the piston head 13 inside and outside the piston cylinder 12, and the piston assembly 5 is arranged inside the piston cylinder 12;

[0036] A lubrication assembly 7, used to spray lubricating oil between the connecting journal 6 and the crank portion 4, and the lubrication assembly 7 is arranged inside the connecting journal 6.

[0037] A flywheel 2 is installed outside the crankshaft 1, and a first pulley 3 is installed at one end of the crankshaft 1 away from the flywheel 2. A belt 14 is meshed and connected to the outside of the first pulley 3, and a second pulley 8 is meshed and connected to the inside of the belt 14.

[0038] A camshaft 9 is installed outside the second pulley 8, and a valve assembly 10 is installed outside the camshaft 9. Both the second pulley 8 and the camshaft 9 are provided with two.

[0039] When using the device, by controlling the lubrication component 7, lubricating oil is sprayed between the crank part 4 and the connecting journal 6 to reduce the wear of the crank part 4 or the connecting journal 6. After using the device, by using the piston component 5, most of the impurities between the valve and the piston can be cleaned up.

[0040] The piston component 5 includes a bottom plate 501. A first hydraulic rod 502 is fixedly connected to the top of the bottom plate 501. A attaching plate 503 is fixedly connected to the top of the first hydraulic rod 502. The attaching plate 503 is arranged in an arc shape. The bottom plate 501 is fixedly connected to the outside of the connecting handle 11, and the bottom plate 501 is installed at the bottom of the piston cylinder 12.

[0041] A connecting rod 504 is fixedly connected to the outside of the attaching plate 503. There are multiple connecting rods 504. A diaphragm is installed on the outside of the connecting rod 504. A first clamping seat 505 is fixedly connected to the top of the attaching plate 503. A second hydraulic rod 506 is fixedly connected to the inside of the first clamping seat 505. A top plate 507 is fixedly connected to the top of the second hydraulic rod 506. A clamping block 508 is fixedly connected to the outside of the top plate 507. The clamping block 508 is snap-fitted with the bottom of the piston head 13.

[0042] Due to the snap-fitting connection between the clamping block 508 and the piston head 13, the piston head 13 is movably installed in the piston cylinder 12, which is convenient for regular maintenance and repair of the inside of the piston cylinder 12. When it is necessary to clean the inside of the piston cylinder 12, the second hydraulic rod 506 is opened. The second hydraulic rod 506 drives the top plate 507 and the clamping block 508 to move upward, and then drives the piston head 13 on the top of the clamping block 508 to move upward, and then manually cleans the inside of the piston cylinder 12.

[0043] Both the second hydraulic rod 506 and the top plate 507 are provided with two and are symmetrically arranged. There are multiple clamping blocks 508.

[0044] A second clamping seat 509 is fixedly connected to the top of the attaching plate 503. A plug rod 510 is fixedly connected to the inside of the second clamping seat 509. A positioning column 511 is fixedly connected to the top of the plug rod 510. A viscous sleeve is sleeved on the outside of the positioning column 511. There are multiple second clamping seats 509.

[0045] When the first hydraulic rod 502 is opened, the first hydraulic rod 502 drives the attaching plate 503 to move upward, and then drives the second clamping seat 509, the plug rod 510, the positioning column 511 and the viscous sleeve to move upward. At the same time, the second hydraulic rod 506 is opened, and the second hydraulic rod 506 drives the piston head 13 to move upward, so that the piston head 13 is separated from the piston. The first hydraulic rod 502 is adjusted to the reciprocating motion mode, and the viscous sleeve absorbs impurities in the area between the valve and the piston during the lifting process, and promotes most of the impurities to adhere and fix on the viscous sleeve.

[0046] The lubrication assembly 7 includes a third hydraulic rod 701. An outer part of the third hydraulic rod 701 is fixedly connected with a first annular plate 702. A spray head 703 is installed inside the first annular plate 702. A storage pipe 704 is installed outside the spray head 703. The third hydraulic rod 701 is fixedly connected inside the connecting journal 6. Both the spray head 703 and the storage pipe 704 are provided with four.

[0047] An outer part of the first annular plate 702 is fixedly connected with a fourth hydraulic rod 705. An outer part of the fourth hydraulic rod 705 is fixedly connected with a second annular plate 706. The second annular plate 706 is set to have a uniform thickness at the outer edge and a thin inner edge. The outer edge contacts the crank part 4. A through hole 707 is formed inside the second annular plate 706. A net plate 708 is installed inside the through hole 707. A plurality of through holes 707 are formed. The through holes 707 are arranged corresponding to the spray heads 703.

[0048] Lubricating oil is pre-stored in the compressible storage pipe 704. The third hydraulic rod 701 and the fourth hydraulic rod 705 are controlled in reverse to control the spraying operation of the lubricating oil. Before using the device, the third hydraulic rod 701 is opened to the maximum stroke. At this time, the fourth hydraulic rod 705 is in the initial state, and the second annular plate 706 is in the connecting journal 6. By turning down the third hydraulic rod 701 by one gear and opening the fourth hydraulic rod 705 to the first gear, the third hydraulic rod 701 drives the first annular plate 702, the spray head 703 and the storage pipe 704 to contact and squeeze the connecting journal. The storage pipe 704 is deformed. The lubricating oil in the storage pipe 704 passes through the spray head 703 and the net plate 708 and is sprayed into the area between the connecting journal 6 and the crank part 4, thereby reducing the friction between the crank part 4 and the connecting journal 6. And during this process, the position of the second annular plate 706 remains unchanged.

[0049] Working principle: When using the device, by controlling the lubrication assembly 7, the lubricating oil is sprayed between the crank part 4 and the connecting journal 6 to reduce the wear of the crank part 4 or the connecting journal 6.

[0050] Lubricating oil is pre-stored in the compressible storage pipe 704. The third hydraulic rod 701 and the fourth hydraulic rod 705 are controlled in reverse to control the spraying operation of the lubricating oil. Before using the device, the third hydraulic rod 701 is opened to the maximum stroke. At this time, the fourth hydraulic rod 705 is in the initial state, and the second annular plate 706 is in the connecting journal 6. By turning down the third hydraulic rod 701 by one gear and opening the fourth hydraulic rod 705 to the first gear, the third hydraulic rod 701 drives the first annular plate 702, the spray head 703 and the storage pipe 704 to contact and squeeze the connecting journal. The storage pipe 704 is deformed. The lubricating oil in the storage pipe 704 passes through the spray head 703 and the net plate 708 and is sprayed into the area between the connecting journal 6 and the crank part 4, thereby reducing the friction between the crank part 4 and the connecting journal 6. And during this process, the position of the second annular plate 706 remains unchanged.

[0051] After using the device, by using the piston assembly 5, most of the impurities between the valve and the piston can be cleaned up.

[0052] Turn on the first hydraulic rod 502. The first hydraulic rod 502 drives the attaching plate 503 to move upward, and then drives the second clamping seat 509, the inserting rod 510, the clamping column 511 and the viscous sleeve to move upward. At the same time, turn on the second hydraulic rod 506. The second hydraulic rod 506 drives the piston head 13 to move upward, separating the piston head 13 from the piston. Adjust the first hydraulic rod 502 to the reciprocating motion mode. During the lifting process, the viscous sleeve absorbs impurities in the area between the valve and the piston, promoting most of the impurities to adhere and fix on the viscous sleeve.

[0053] The piston head 13 is detachably connected to the piston barrel 12 by the clamping block 508, enabling the piston head 13 to be movably installed in the piston barrel 12, which is convenient for regular maintenance and repair of the interior of the piston barrel 12. When it is necessary to clean the interior of the piston barrel 12, turn on the second hydraulic rod 506. The second hydraulic rod 506 drives the top plate 507 and the clamping block 508 to move upward, and then drives the piston head 13 at the top of the clamping block 508 to move upward, thereby manually cleaning the interior of the piston barrel 12.

[0054] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
