[0019] In the picture: Detailed Implementation

[0020] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0021] like Figures 1 to 5As shown, this utility model provides a vertical shaft hydraulic lubrication system, including an oil tank assembly a, an oil supply motor pump assembly b, a hydraulic valve assembly c, a housing d, a lubrication assembly e, a terminal block assembly, and a working oil port assembly. The oil outlet of the oil tank assembly a is connected to the inlet of the oil supply motor pump assembly b, the outlet of the oil supply motor pump assembly b is connected to the inlet of the hydraulic valve assembly c, the oil outlet of the hydraulic valve assembly is connected to the inlet of the lubrication assembly, and the inlet of the lubrication assembly is connected to the return port of the oil tank assembly. The hydraulic valve assembly is installed in the hydraulic system, and the lubrication assembly is installed in the lubrication system.

[0022] The oil supply motor pump assembly b is the power core of the hydraulic and lubrication systems. Its core function is to convert electrical energy into the pressure energy or kinetic energy of the oil, providing a continuous and stable fluid delivery to the system. One feasible implementation is as follows: the oil supply motor pump assembly b includes a motor and a drive hydraulic pump. The motor drives the hydraulic pump to rotate via a coupling. The hydraulic pump uses internal volume changes to create a vacuum, drawing oil from the oil tank.

[0023] The oil tank assembly a is used to store the hydraulic oil, the working medium of the hydraulic unit, and serves to settle impurities, dissipate heat, and collect hydraulic oil that flows out during disassembly and maintenance.

[0024] Specifically, the oil tank assembly a includes an oil tank, and a level gauge 4 is installed on the side wall of the oil tank. The level gauge 4 is connected to the inside of the oil tank and directly displays the oil level inside the assembly. This allows for the detection of the oil level, enabling operators to visually observe the oil height and improving the safety and stability of the hydraulic system. A float-type level sensor is also installed inside the oil tank to detect the oil level, enabling continuous and remote monitoring.

[0025] An air filter 13 is installed on the top of the oil tank, and is connected to the interior of the oil tank. The air filter 13 allows air to enter the oil tank, effectively preventing larger particles from entering the hydraulic fluid and ensuring the safety of the hydraulic system. A heater 8 is installed on the side wall of the oil tank, inserted into the interior of the tank. The heater 8 heats the hydraulic oil in the tank, maintaining the oil temperature within a suitable operating range and ensuring stable oil performance. A temperature switch 7 is also installed on the side wall of the oil tank, connected to the interior of the tank, for continuous and remote monitoring of the oil temperature, ensuring stable system temperature.

[0026] Hydraulic valve assembly C serves as the main system's oil supply circuit, supplying pressurized oil to the hydraulic cylinders and lubrication circuit. It is simple and convenient to operate and easy to maintain. Hydraulic valve assembly C can provide pressure feedback to the hydraulic system, release internal pressurized oil, switch to open a release oil circuit, provide maximum system pressure safety protection, and achieve interlocking and long-term internal pressure holding. Controlling hydraulic valve assembly C enables overload protection of the hydraulic cylinders and serves as the actuator for the hydraulic cylinders, providing a stable and safe power source, allowing the hydraulic cylinders to complete related tasks more accurately, conveniently, and stably.

[0027] Specifically, the hydraulic valve assembly c includes a solenoid directional valve 24, a first pilot-operated check valve 21, and a second pilot-operated check valve 22. One end of the solenoid directional valve 24 is connected to the oil inlet of the hydraulic valve assembly, and the other end of the solenoid directional valve 24 is connected to one end of the first pilot-operated check valve 21 and one end of the second pilot-operated check valve 22, respectively. The solenoid directional valve 24 can control the oil flow direction, thereby controlling the reversing of the actuator. The other ends of the first pilot-operated check valve 21 and the second pilot-operated check valve 22 are connected to the first oil outlet A and the second oil outlet B of the hydraulic system, respectively, which can achieve locking and long-term internal pressure holding, allowing the hydraulic cylinder to remain in the same position for a long time.

[0028] The hydraulic valve assembly c also includes a first relief valve 23. The two ends of the first relief valve 23 are connected to the oil inlet of the hydraulic valve assembly c and the oil inlet of the lubrication assembly e, respectively. The relief pressure is set to 70 bar, which can effectively ensure that the pressure inside the hydraulic valve assembly c will never exceed 70 bar.

[0029] The hydraulic valve assembly c also includes a pressure sensor 6, a first pressure gauge 15, and a second pressure gauge 18, which are connected to the hydraulic system circuit to monitor the system pressure in real time, greatly increasing the safety of the system.

[0030] The hydraulic valve assembly c provides pressure feedback of the hydraulic system through the first pressure gauge 15, the second pressure gauge 18 and the pressure sensor 6, releases the internal pressure oil through the shut-off valve 25, controls the oil flow direction through the solenoid directional valve 24, provides maximum system pressure safety protection through the first relief valve 23, and can achieve lock-in and long-term internal pressure maintenance through the first hydraulic control check valve 21 and the second hydraulic control check valve 22.

[0031] The lubrication component e can filter the hydraulic oil in the hydraulic system and provide filter blockage alarm feedback. It can also cool the hydraulic oil entering the lubrication system, maintaining the oil temperature within a suitable operating range, and monitor the oil temperature and flow rate in real time. Controlling the lubrication component e enables oil supply and filtration cooling of the lubrication system, providing a stable and safe power source, and allowing the lubrication system to complete its tasks more accurately, conveniently, and stably.

[0032] Specifically, the lubrication component e includes a filter 28 and an air cooler 20. The two ends of the filter 28 are connected to the oil inlet of the lubrication component e and the air cooler 20, respectively. This effectively prevents large-diameter solid particles from entering the lubrication circuit and actuator, causing oil circuit blockage or valve jamming. When the filter element becomes contaminated and the inlet oil pressure difference reaches 0.35 MPa, a switch signal is issued, requiring filter element replacement to ensure the safety of the lubrication system and extend its service life. The two ends of the air cooler 20 are connected to the filter 28 and the oil outlet of the lubrication component e, respectively. The air cooler 20 cools the hydraulic oil, maintaining the oil temperature entering the lubrication system within a suitable operating range, thus ensuring stable oil performance.

[0033] The lubrication assembly e also includes a second overflow valve 27. The two ends of the second overflow valve 27 are connected to the oil inlet of the lubrication assembly e and the oil return port of the oil tank assembly a, respectively. The overflow pressure is set to 5 bar, which can effectively ensure that the pressure in the lubrication circuit will never exceed 5 bar, thus ensuring the safety of the lubrication system.

[0034] The lubrication assembly e also includes a flow sensor 14, a first pointer pressure gauge, and a thermometer 11. The flow sensor 14, the first pointer pressure gauge, and the thermometer 11 are connected to the front end of the oil outlet of the lubrication assembly e to monitor the pressure, temperature, and flow of the lubrication system in real time, ensuring the safety and stability of the lubrication system.

[0035] The lubrication assembly e also includes a temperature sensor 12, a second pointer pressure gauge and a thermometer. The temperature sensor 12, the second pointer pressure gauge and the thermometer are connected between the oil inlet of the lubrication assembly e and the oil tank assembly a, and monitor the temperature and pressure of the hydraulic oil returning to the oil tank of the lubrication system in real time.

[0036] The working port assembly brings together the first oil outlet A and the second oil outlet B of the hydraulic valve assembly c and the oil outlets on the lubrication assembly e on the same surface for easy connection by the user.

[0037] The terminal box assembly f includes a terminal box. The terminal box assembly f connects all the wiring harnesses of the electrical components of the hydraulic valve assembly c and the lubrication assembly e to the terminals in the terminal box, serving as the external electrical interface of the hydraulic lubrication system for convenient unified connection by the user. In addition, all the wiring harness shielding layers are connected to the terminal box, which enables the wiring harnesses of all electrical components to be grounded.

[0038] The entire hydraulic lubrication system is also equipped with a cover d to protect the components of the hydraulic system and ensure the safety and stability of the hydraulic system in harsh environments.

[0039] This invention integrates the hydraulic and lubrication systems of a vertical shaft equipment into a single system. The hydraulic system boasts high power density, fast response speed, and high precision, while the lubrication system adjusts its lubrication status in real time based on temperature, pressure, and flow parameters. It can operate reliably for extended periods in harsh and complex environments, providing safer and more stable power. This hydraulic lubrication system enables the vertical shaft equipment to complete its tasks more accurately, conveniently, and stably.
