Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and more specifically, to a hydraulic cylinder. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] Existing technologies disclose several patent documents involving hydraulic cylinders. Chinese Patent Application No. CN201922016851.6 discloses a hydraulic cylinder including a cylinder body and a piston, with the piston housed inside the cylinder body. Beneficial effects: This utility model employs an outer rod, a first support wheel, a handle bolt, a top block, and a moving block. The first support wheel abuts against the piston rod from multiple directions, supporting the piston rod between the piston and the end cap, increasing the support points and preventing piston rod wobbling. During piston rod movement, the first support wheel rotates, eliminating the need for a traditional guide rod, reducing friction between the guide rod and the piston rod, making piston rod movement more flexible, and improving the efficiency of the device. When the first support wheel wears down after prolonged use, the operator can push the top block inward by rotating the handle bolt. The top block pushes the moving block to compress the first support wheel, thereby adjusting the clamping force between the first support wheel and the piston rod, ensuring the first support wheel always presses firmly against the piston rod and guaranteeing the stability of piston rod movement.

[0004] In the aforementioned patent, the hydraulic cylinder has poor heat dissipation during use, which affects its lifespan. Therefore, we propose a new type of hydraulic cylinder. Utility Model Content

[0005] Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a hydraulic cylinder. When cooling the main body of the hydraulic cylinder, the plug is opened, and then an external water pipe is inserted into the water cooling pipe. The water cooling pipe cools the inside of the sleeve, and the sleeve cools the surface of the main body of the hydraulic cylinder, thereby optimizing the service life of the main body of the hydraulic cylinder.

[0007] Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solution:

[0009] A hydraulic cylinder, comprising:

[0010] Positioning plate number one;

[0011] The hydraulic cylinder body is mounted on the No. 1 positioning plate;

[0012] Positioning plate number one is located on the side of positioning plate number two, and positioning plate number two is engaged with the hydraulic cylinder body.

[0013] The long screw is provided in multiple ways. All of the long screws are fixedly connected to the side end of the first positioning plate, and all of the long screws are movably connected through the second positioning plate. All of the long screws are threaded with nuts.

[0014] A heat dissipation mechanism is mounted on the first positioning plate and is connected to the main body of the hydraulic cylinder.

[0015] In a preferred embodiment of the present invention, the heat dissipation mechanism includes a support component and a heat dissipation component, both of which are disposed on a first positioning plate and are connected to each other.

[0016] In a preferred embodiment of this utility model, the support component includes a sleeve and a receiving groove. The sleeve is movably inserted into the surface of the hydraulic cylinder body, and the receiving groove is located at the right end of the sleeve.

[0017] As a preferred embodiment of the present invention, the heat dissipation component includes through holes and water cooling pipes. There are two through holes, both of which are opened on the sleeve. The water cooling pipes are installed in the receiving groove and are movably inserted into the two through holes.

[0018] As a preferred embodiment of this utility model, both ends of the water-cooling pipe are movably connected with plugs.

[0019] In a preferred embodiment of this utility model, the surface of the sleeve is fixedly connected to a plurality of guide seats, and the plurality of guide seats are slidably connected to the surface of a plurality of long screws.

[0020] As a preferred embodiment of this utility model, both the No. 1 positioning plate and the No. 2 positioning plate have multiple mounting holes on their side ends.

[0021] Beneficial effects

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] (1) When it is necessary to cool down the hydraulic cylinder body, open the plug and insert the water cooling pipe through the external water pipe. The water cooling pipe cools down the sleeve. The water cooling pipe circulates in the sleeve and directly cools down the hydraulic cylinder body, effectively reducing the working temperature and extending the equipment life. The sleeve cools down the surface of the hydraulic cylinder body, thereby optimizing the service life of the hydraulic cylinder body.

[0024] (2) Multiple long screws pass through the No. 2 positioning plate on the side end and are fixed by nuts, providing uniform preload to ensure a stable connection between the hydraulic cylinder body and the No. 2 positioning plate, while allowing fine adjustment to adapt to different installation requirements. The guide seat slides with the screw: the guide seat on the sleeve surface slides along the long screw, ensuring the axial stability of the sleeve and preventing rotational offset, adapting to the dynamic working conditions of the hydraulic cylinder. The guide seat is designed to facilitate sliding cooperation with the long screw, thereby facilitating the positioning of the sleeve and preventing the sleeve from rotating.
