Description

Technical Field

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

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device, eliminates transmission backlash, and provides smooth movement, thus finding wide application in the hydraulic systems of various machines. The output force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and the pressure difference between its two sides. A hydraulic cylinder basically consists of a cylinder barrel, piston and piston rod, sealing devices, cushioning devices, and venting devices. The cushioning and venting devices are optional depending on the specific application, while the other devices are essential.

[0003] Hydraulic cylinders are generally at risk of insufficient cooling during operation, especially under high load, long-term operation or high ambient temperature. Overheating of hydraulic cylinders can lead to deterioration of hydraulic oil performance, collapse of system reliability, accelerated wear of mechanical components, and a precipitous reduction in the lifespan of hydraulic cylinders.

[0008] Preferably, a number of cooling fins are fixedly connected to the outside of the hydraulic cylinder, and the cooling fins are disposed between the mounting plate and the lower mounting box.

[0009] Preferably, the upper and lower ends of the hydraulic cylinder are fixedly connected to support rings, and the support rings have several sets of mounting grooves on the side facing the mounting plate and the lower mounting box, with rolling balls rotatably connected inside the mounting grooves.

[0010] Preferably, a protective net is fixedly connected between the mounting plate and the outer side of the lower mounting box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a first motor to drive a fan, which draws air into the lower mounting box through the intake pipe, then into the vent pipe, and finally blows it outwards from the outlet pipe to the outside of the hydraulic cylinder, accelerating heat dissipation on the outside of the hydraulic cylinder. A second motor drives a connecting gear, which in turn rotates the mounting plate via a gear ring, thereby rotating the vent pipe. This allows the outlet pipe to blow air to various locations on the outside of the hydraulic cylinder, improving the heat dissipation efficiency of the hydraulic cylinder body and extending the service life of the hydraulic cylinder.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a hydraulic cylinder with a cooling function, including a hydraulic cylinder 1, a mounting plate 2 rotatably mounted on the upper part of the hydraulic cylinder 1, several sets of vent pipes 4 fixedly welded to the lower part of the mounting plate 2, a lower mounting box 3 fixedly welded to the lower part of the vent pipes 4, several sets of air outlet pipes 5 fixedly welded to the side of the vent pipes 4 facing the hydraulic cylinder 1, the lower mounting box 3 rotatably connected to the outside of the hydraulic cylinder 1, and an air inlet pipe 6 fixedly welded to the lower inside of the lower mounting box 3. Air enters the lower mounting box 3 through the air inlet pipe 6, then enters the vent pipes 4, and is blown towards the hydraulic cylinder 1 through the air outlet pipes 5. Outside the hydraulic cylinder 1, to accelerate heat dissipation, a gear ring 11 is fixedly welded to the upper part of the mounting plate 2, and an upper mounting box 12 is fixedly welded to the upper outer part of the hydraulic cylinder 1. A second motor 13 is installed in the flange inside the upper mounting box 12. The power end of the second motor 13 passes through the upper mounting box 12 and is connected to a connecting gear 14 via a coupling. The connecting gear 14 meshes with the gear ring 11. The second motor 13 drives the connecting gear 14, which in turn drives the mounting plate 2 to rotate through the gear ring 11, thereby driving the vent pipe 4 to rotate, so that the vent pipe 5 can blow air to various positions outside the hydraulic cylinder 1.

[0020] Two adjacent sets of air outlet pipes 5 are staggered to ensure that the air outlet pipes 5 are offset vertically and can blow air to various positions outside the hydraulic cylinder 1; a mounting bracket 7 is fixedly welded inside the air inlet pipe 6, and a first motor 8 is mounted on a flange on one side of the mounting bracket 7. A fan 9 is connected to the power end of the first motor 8 via a coupling. The first motor 8 drives the fan 9, thereby drawing air from the air inlet pipe 6 into the lower mounting box 3. Isolation nets 10 are fixedly welded inside both ends of the air inlet pipe 6 to isolate the fan 9 structure from the outside; several sets of heat dissipation fins 15 are fixedly welded to the outside of the hydraulic cylinder 1. The heat dissipation fins 15 are set on the mounting box 3. Between the mounting plate 2 and the lower mounting box 3, the heat dissipation area on the outside of the hydraulic cylinder 1 is increased to improve heat dissipation efficiency; support rings 16 are fixedly welded to the upper and lower ends of the hydraulic cylinder 1 to fix the installation position of the mounting plate 2 and the lower mounting box 3. Several sets of mounting grooves 17 are opened on the side of the support ring 16 facing the mounting plate 2 and the lower mounting box 3. Rolling balls 18 are rotatably installed inside the mounting grooves 17 to reduce the friction between the mounting plate 2, the lower mounting box 3 and the support ring 16; a protective net 19 is fixedly welded between the outer sides of the mounting plate 2 and the lower mounting box 3 to protect the vent pipe 4.

[0021] Working principle: When in use, the first motor 8 drives the fan 9, which draws air into the lower mounting box 3 through the air inlet pipe 6, then into the vent pipe 4, and finally blows it outward from the air outlet pipe 5 to the outside of the hydraulic cylinder 1, thus accelerating the heat dissipation of the outside of the hydraulic cylinder 1. The second motor 13 drives the connecting gear 14, which drives the mounting plate 2 to rotate through the gear ring 11, thereby driving the vent pipe 4 to rotate, so that the air outlet pipe 5 can blow air to various positions on the outside of the hydraulic cylinder 1, improving the heat dissipation efficiency of the hydraulic cylinder 1.
