[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] like Figure 1-4 As shown: The technical solution provided by this embodiment is as follows:

[0021] A novel hydraulic cylinder, characterized in that it comprises: a support base 1, a cylinder barrel 2 is mounted on the support base 1, a piston rod 3 matched with the cylinder barrel 2 is arranged on the upper part of the cylinder barrel 2; a first infusion valve 4 and a second infusion valve 5 are also arranged on the side wall of the cylinder barrel 2; a cleaning mechanism 6 is arranged at the intersection of the top surface of the cylinder barrel 2 and the piston rod 3;

[0022] The cleaning mechanism 6 includes a cleaning shell 601 installed on the top of the cylinder 2 and sleeved on the outer periphery of the piston rod 3; the interior of the cleaning shell 601 is rotatably connected to a transmission gear ring 602, a servo motor 605 is installed on the side of the cleaning shell 601, and the output shaft of the servo motor 605 is provided with a rotating gear 604; the rotating gear 604 is meshed with the transmission gear ring 602; the inner side of the transmission gear ring 602 is also provided with a friction ring 603 that fits the piston rod 3.

[0023] After the piston rod 3 moves downward, the friction ring 603 scrapes its surface to clean it, thereby reducing the probability that impurities stick to the piston rod 3 and affect the use of the hydraulic cylinder.

[0024] During actual use, when the servo motor 605 is started, its output shaft drives the rotating gear 604 to rotate, and the rotating gear 604 drives the transmission gear ring 602 and the friction ring 603 to rotate, thereby cleaning the surface of the piston rod 3.

[0025] The support base 1 is provided with a reinforcement mechanism 8 for reinforcing the cylinder 2;

[0026] The reinforcement mechanism 8 includes a first reinforcement ring 801 and a second reinforcement ring 802 which are sequentially sleeved on the outer surface of the cylinder 2 from top to bottom. The first reinforcement ring 801 is hinged with a plurality of connecting rods 803 in an annular array, and the other end of the connecting rod 803 is hinged with a sliding block 804.

[0027] A plurality of dampers 806 are installed in a circular array on the support base 1, the sliding block 804 is installed in the damper 806, and a buffer spring 807 is installed in the damper 806;

[0028] The second reinforcement ring 802 is connected to a plurality of spring telescopic rods 805 in a ring array, and the other ends of the spring telescopic rods 805 are hinged to the connecting rod 803 .

[0029] The first reinforcement ring 801 is subjected to an impact force which generates a force on the connecting rod 803. At the same time, the second reinforcement ring 802 transmits the pressure to the connecting rod 803 through the spring telescopic rod 805. The movement of the connecting rod 803 drives the sliding block 804 to move on the surface of the support base 1, and applies pressure to the damper 806 and the buffer spring 807. At this time, the damper 806 and the buffer spring 807 absorb the pressure, thereby reducing the force acting on the cylinder 2.

[0030] The surface of the cylinder 2 is also provided with a guide mechanism 7; the guide mechanism 7 includes a guide seat 701, a guide rod and a guide plate 703; the guide seat 701 is mounted on the surface of the cylinder 2, and the guide seat 701 is provided with a guide hole running through the upper and lower parts, and the guide rod 702 is arranged in the guide hole; the top of the guide rod 702 is connected to the guide plate 703, and the guide plate 703 is fixedly connected to the piston rod 3.

[0031] The height of the guide plate 703 is always higher than the height of the servo motor 605. This can prevent the piston rod 3 from contracting and exerting a force on the servo motor 605.

[0032] When the piston rod 3 moves, it moves on the surface of the guide plate 703 , and at the same time, the guide seat 701 and the guide rod 702 support the guide plate 703 , thereby increasing the stability of the piston rod 3 when moving.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
