Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinder covers, in particular to a hydraulic oil cylinder cover with a protection mechanism. Background Art

[0002] The hydraulic cylinder head is a compression seal component, usually made of cast iron, cast steel or aluminum alloy. It can be used in conjunction with the hydraulic cylinder barrel to provide pressure sealing, prevent fluid leakage, and mount components and additional components.

[0003] A Chinese utility model patent, publication number CN210265339U, discloses a hydraulic cylinder head with a dustproof function. This device uses a spring to squeeze a sealing gasket, thereby making the sealing gasket fit more closely to the outer wall of the piston rod. The double-layer sealing gasket can prevent dust from directly entering the hydraulic cylinder. Regarding the related art mentioned above, the inventor believes that there are the following defects:

[0004] Although this device can prevent dust from entering the interior of the hydraulic cylinder during actual use, it lacks an integrated structure that can remove dust accumulated on the surface of the cylinder head. In addition, the hydraulic cylinder will generate a large amount of heat after long-term use, so the dust coverage will affect the normal dissipation of heat, thereby accelerating the consumption of oil. For this reason, we provide a hydraulic cylinder head with a protective mechanism. Utility Model Content

[0005] In order to solve the problem in the above background technology that the normal heat dissipation of the hydraulic cylinder is affected due to the lack of an integrated structure that can automatically clean the dust on the cylinder cover surface, the utility model provides a hydraulic cylinder cover with a protective mechanism.

[0006] The utility model adopts the following technical solutions: a hydraulic cylinder cover with a protective mechanism, comprising:

[0007] A cylinder body, a cylinder cover is fixedly connected to the top of the cylinder body, and a piston rod is provided on the cylinder body;

[0008] A dust removal assembly, the dust removal assembly includes a gear ring rotatably connected to the outside of the cylinder head, one side of the cylinder body is rotatably connected to gear 1 through a bracket, and gear 1 is meshed with the gear ring, the top of the gear 1 is coaxially fixedly connected to a conical wheel 1, the bracket is also rotatably connected to a conical wheel 2 and meshed with the conical wheel 1, one side of the conical wheel 2 is coaxially fixedly connected to a gear 2, the external fixed sleeve of the piston rod is provided with a connecting frame, the end of the connecting frame is fixedly connected to a bar frame, the inner side of the bar frame is provided with teeth and meshed with the gear 2;

[0009] An L-shaped connecting seat is fixedly connected to a liquid storage tank, and a cleaning sponge is fixedly connected to the bottom of the liquid storage tank.

[0010] As a further improvement of the above solution, a through hole matching the diameter of the piston rod is opened in the center of the cylinder cover.

[0011] As a further improvement of the above solution, a liquid injection pipe is fixedly connected to the center of the top of the liquid storage tank, and a sealing cover is added to the top of the liquid injection pipe.

[0012] As a further improvement of the above solution, leakage holes are symmetrically and equidistantly provided on the bottom of the liquid storage tank.

[0013] As a further improvement of the above solution, the length of the cleaning sponge is consistent with the radius of the cylinder head.

[0014] As a further improvement of the above solution, the end of the cleaning sponge close to the piston rod is arranged in an arc-shaped structure and fits the surface of the piston rod.

[0015] As a further improvement of the above solution, the length of the bar frame is slightly larger than the stroke of the piston rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model controls the piston rod to extend and retract, and the piston rod also drives the bar frame fixedly connected to the bar frame through the connecting frame to move together. The movement of the bar frame drives the teeth to move, so that the gear 2 engaged with the teeth can be driven to rotate. The rotation of the gear 2 drives the conical wheel 2 to rotate. The meshing action between the conical wheel 2 and the conical wheel 1 can drive the gear 1 to rotate. The rotation of the gear 1 drives the gear ring to rotate, thereby driving the cleaning sponge to rotate to clean the dust on the surface of the cylinder head, effectively avoiding the problem of affecting the normal heat dissipation of the hydraulic cylinder due to the lack of an integrated structure that can automatically clean the dust on the surface of the cylinder head, and has strong practicality.

[0018] 2. The utility model adds volatile liquid into the liquid storage tank, and the volatile liquid seeps out from the leakage hole and is absorbed by the cleaning sponge. As the cleaning sponge rotates, the volatile liquid can be evenly applied to the surface of the cylinder head. The volatilization of the volatile liquid can quickly take away the heat, thereby achieving the purpose of quickly cooling the cylinder head and further improving the practicality of the device.

[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1:

[0026] Please combine Figure 1-3 , a hydraulic cylinder head with a protective mechanism according to this embodiment includes:

[0027] Cylinder body 1, the top of the cylinder body 1 is fixedly connected to the cylinder cover 2, the cylinder body 1 is provided with a piston rod 3, and the center of the cylinder cover 2 is provided with a through hole that matches the diameter of the piston rod 3, so that the piston rod 3 can be freely extended and retracted;

[0028] The dust removal assembly includes a gear ring 101 rotatably connected to the outside of the cylinder head 2, a gear 102 rotatably connected to one side of the cylinder body 1 through a bracket, and the gear 102 is meshed with the gear ring 101, and the top of the gear 102 is coaxially fixedly connected to a conical wheel 103, and the bracket is also rotatably connected to a conical wheel 2 104 and meshed with the conical wheel 103, and one side of the conical wheel 2 104 is coaxially fixedly connected to a gear 2 105, and the outer fixed sleeve of the piston rod 3 is provided with a connecting frame 106, and the end of the connecting frame 106 is fixedly connected to a bar frame 107, and the inner side of the bar frame 107 is provided with teeth 108 and meshed with the gear 2 105;

[0029] An L-shaped connecting seat 109 is fixedly connected to a liquid storage tank 110, and a cleaning sponge 111 is fixedly connected to the bottom of the liquid storage tank 110. The cleaning sponge 111 contacts the surface of the cylinder head 2. The top center of the liquid storage tank 110 is fixedly connected to a liquid injection pipe 4. A sealing cover is provided on the top of the liquid injection pipe 4 to facilitate the addition of volatile liquid into the liquid storage tank 110 and to prevent the volatile liquid from evaporating. Leakage holes 112 are symmetrically provided at the bottom of the liquid storage tank 110 to facilitate the automatic penetration of the volatile liquid into the cleaning sponge 111. The length of the cleaning sponge 111 is consistent with the radius of the cylinder head 2. The end of the cleaning sponge 111 close to the piston rod 3 is arranged in an arc-shaped structure and fits into the surface of the piston rod 3, which can ensure the thorough cleaning of the cylinder head 2.

[0030] The implementation principle of a hydraulic cylinder head with a protective mechanism in the embodiment of the present application is as follows: while controlling the piston rod 3 to extend and retract, the piston rod 3 will also drive the bar frame 107 fixedly connected to it through the connecting frame 106 to move together, and the movement of the bar frame 107 drives the teeth 108 to move, so that the gear 2 105 meshing with the teeth 108 can be driven to rotate, and the rotation of the gear 2 105 drives the conical wheel 2 104 to rotate. The meshing action between the conical wheel 2 104 and the conical wheel 1 103 can drive the gear 1 102 to rotate, and the rotation of the gear 102 drives the gear ring 101 to rotate, thereby driving the cleaning sponge 111 to rotate to clean the dust on the surface of the cylinder head 2. At the same time, the volatile liquid inside the liquid storage tank 110 will seep out through the leakage hole 112 and be absorbed by the cleaning sponge 111. As the cleaning sponge 111 rotates, the volatile liquid can be evenly applied to the surface of the cylinder head 2. The volatilization of the volatile liquid can quickly take away the heat, thereby achieving the purpose of quickly cooling the cylinder head 2.

[0031] Example 2:

[0032] This embodiment is further improved on the basis of the embodiment 1 in that the length of the bar frame 107 is slightly larger than the stroke of the piston rod 3, so as to ensure the stable and normal operation of the dust removal assembly.

[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
