Description

Technical Field

[0001] The utility model relates to the field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder piston rod. Background Art

[0002] In the hydraulic transmission system, the hydraulic cylinder is a key actuator, and its performance directly affects the stability and efficiency of the entire system. The hydraulic cylinder realizes energy conversion and transmission through the reciprocating motion of the piston rod. However, during long-term use, the outer wall of the piston rod is often gradually contaminated due to the adhesion of dust, oil and other pollutants in the working environment. These pollutants not only increase the friction resistance between the piston rod and the inner wall of the hydraulic cylinder, but also are brought into the hydraulic system with the flow of oil during the reciprocating motion of the piston rod, resulting in the accumulation of impurities in the system, thereby affecting the cleanliness of the hydraulic oil and the operating efficiency of the system.

[0003] Traditional hydraulic cylinder designs often ignore the cleaning of the outer wall of the piston rod and lack an effective automatic cleaning mechanism. When the outer wall of the piston rod is contaminated, it is usually necessary to manually stop the machine for cleaning, which not only increases maintenance costs, but also affects production efficiency and continuous operation of the equipment. In addition, even if manual cleaning is performed, it is still difficult to avoid the accumulation of impurities between the piston rod and the hydraulic cylinder due to incomplete cleaning or too long cleaning cycle, thereby aggravating the wear and failure rate of the system.

[0004] Therefore, it is necessary to provide a new hydraulic cylinder piston rod to solve the above technical problems. Utility Model Content

[0029] The working principle of the hydraulic cylinder piston rod provided by the utility model is as follows:

[0030] Basic structure:

[0031] The cylinder body 1 is slidably connected to the piston rod 2, and the piston rod 2 reciprocates in the cylinder body 1;

[0032] The connecting ring 3 is fixed to one end of the cylinder body 1, and the cleaning ring 4 is connected to the connecting ring 3 by a rotating connection. A brush ring 5 is fixed to the outside of the cleaning ring 4 for cleaning dirt on the outer wall of the piston rod 2;

[0033] The transmission groove wheel 6 is installed on the inner wall of the connecting ring 3 and is rollingly connected with the outer wall of the piston rod 2 to transmit the movement of the piston rod;

[0034] Transmission mechanism 9 works:

[0035] When the piston rod 2 moves in the cylinder body 1, the extension shaft 91 is driven to rotate through the transmission groove wheel 6;

[0036] The driving sprocket 92 at one end of the extension shaft 91 rotates accordingly, and is connected to the driven sprocket 95 through a chain, driving the worm 94 to rotate;

[0037] The worm 94 meshes with the worm wheel 93 on the outside of the cleaning circle 4, so that the cleaning circle 4 and the brush circle 5 thereon rotate around the piston rod 2 to perform the cleaning operation;

[0038] Reciprocating mechanism 10 works:

[0039] The driving bevel gear 103 at one end of the worm 94 meshes with the driven bevel gear 102 at one end of the reciprocating screw 101 to convert the rotational motion of the worm 94 into the reciprocating linear motion of the reciprocating screw 101;

[0040] The linear motion of the reciprocating screw rod 101 drives the piston 105 in the air pump 104 to reciprocate, and when the piston 105 moves up and down, the air is filled from the air pump 104 into the air storage tank 7;

[0041] One-way air inlet valves are installed inside the piston 105 and the conduit to ensure one-way air flow;

[0042] Cleaning process:

[0043] When the piston 105 moves downward in the air pump 104, the air in the air tank 7 is compressed and ejected through the air outlet 8 on the connecting ring 3 and the air guide hole 11 in the cleaning ring 4, forming an air flow to assist the brush ring 5 in cleaning the dirt on the outer wall of the piston rod 2;

[0044] The microfiber glasses cloth on the inner wall of the cleaning ring 4 provides an additional cleaning effect, ensuring that the surface of the piston rod 2 is clean and smooth;

[0045] Limit and support:

[0046] The limiting rod 12 at one end of the piston rod 2 is slidably connected to the outer wall of the cylinder body 1 to ensure the stability of the piston rod 2 during reciprocating motion;

[0047] The bracket 13 on one side of the cylinder body 1 is rotatably connected to the worm 94 to provide a stable support for the worm 94 .

[0048] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
