Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinders, in particular to a multi-stage hydraulic cylinder with a heat dissipation function. Background Technique

[0002] An oil cylinder, namely a hydraulic cylinder, is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input quantities of the hydraulic cylinder are the flow rate and pressure of the fluid, and the outputs are the linear motion speed and force. The piston of the hydraulic cylinder can complete linear reciprocating motion, and the output linear displacement is limited. The hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion.

[0003] For example, in the multi-stage hydraulic cylinder with the application number 202220881813.6, before the oil cylinder body acts, the adjusting screw is rotated downward, so that the adjusting screw pushes the slider to slide downward. During the downward movement of the slider, the supporting rod is manually rotated to form a stable triangular structure among the supporting rod, the oil cylinder body and the ground, effectively preventing the oil cylinder body from tipping during operation. The structure is reasonable and can improve the operation stability of the oil cylinder body. However, the multi-stage hydraulic cylinder body only dissipates heat from the cylinder body through the body material, resulting in poor heat dissipation performance.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a multi-stage hydraulic cylinder with a heat dissipation function is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-stage hydraulic cylinder with a heat dissipation function to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A multi-stage hydraulic cylinder with a heat dissipation function includes a multi-stage cylinder body and a plurality of heat dissipation fins fixedly connected to the outer cylindrical surface of the multi-stage cylinder body. A chassis is arranged on the lower surface of the multi-stage cylinder body, a motor frame is fixedly connected to the lower surface of the chassis, a fixed frame is fixedly connected to the lower outer cylindrical surface of the multi-stage cylinder body, and a heat dissipation mechanism is arranged by extending from the outside to the inside of the chassis.

[0007] Preferably, the heat dissipation mechanism includes a heat dissipation blade ring arranged inside the chassis, and the heat dissipation blade ring is rotatably connected to the outer cylindrical surface of the multi-stage cylinder body. A drive motor is fixedly connected to the lower surface of the motor frame, a drive gear is fixedly connected to the output end of the drive motor, and a gear ring is fixedly connected to the lower surface of the heat dissipation blade ring.

[0008] Preferably, the lower surface of the motor frame extends into the inside of the chassis and is threadedly connected with a first screw, and the number of the first screws is four.

[0009] Preferably, a screw hole is provided at the middle position of the lower surface of the multi-stage oil cylinder body, and the number of screw holes is four.

[0010] Preferably, the lower surface of the chassis extends into the screw hole and is threadedly connected with a second screw, and the number of second screws is four.

[0011] Preferably, a mesh pad is provided between the chassis and the multi-stage oil cylinder body, and a protective net is provided between the chassis and the fixed frame.

At the same time, the heat dissipation blade ring can rotate to blow air upward to the heat dissipation fins for heat dissipation. This design can improve the heat dissipation efficiency of the heat dissipation fins.

[0021] As Figures 1-4 shown, a multi-stage hydraulic cylinder with a heat dissipation function includes a multi-stage cylinder body and a plurality of heat dissipation fins fixedly connected to the outer cylindrical surface of the multi-stage cylinder body.

The heat dissipation fins are made of aluminum plates. The heat dissipation mechanism includes a heat dissipation blade ring provided inside the chassis, and the heat dissipation blade ring is rotatably connected to the outer cylindrical surface of the multi-stage cylinder body. A driving motor is fixedly connected to the lower surface of the motor frame, a driving gear is fixedly connected to the output end of the driving motor, and a gear ring is fixedly connected to the lower surface of the heat dissipation blade ring. The teeth on the outer cylindrical surfaces of the driving gear and the gear ring are engaged.

[0022] By adopting the above technical solution, the heat of the multi-stage cylinder body can be transferred to the heat dissipation fins for heat dissipation. At the same time, the driving motor on the motor frame can be started. The driving motor can drive the driving gear to rotate, and the driving gear can drive the gear ring and the heat dissipation blade ring to rotate to blow air upward to dissipate heat from the heat dissipation fins.

[0023] As Figure 1 、 Figure 3 and Figure 4 shown, the lower surface of the motor frame extends into the inside of the chassis and is threadedly connected with four first screws.

[0024] By adopting the above technical solution, screw holes for fixing the first screws are provided on the lower surface of the motor frame. Removing the first screws can maintain the driving motor and the driving gear.

[0025] Furthermore, screw holes are provided at the middle position of the lower surface of the multi-stage cylinder body, and the number of the screw holes is four.

This is the working principle of this multi-stage hydraulic cylinder with a heat dissipation function.
