[0106] 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.

[0107] This utility model provides a hydraulically lubricated integrated power station for a crusher, such as... Figure 1 As shown, the system includes a lubrication system, a hydraulic transmission system, a bracket 1, an oil tank 3, a heating component 4, and a control system. The lubrication system, the hydraulic transmission system, and the oil tank 3 are all mounted on the bracket 1. The heating component 4 is mounted on the oil tank 3. The control system is connected to the lubrication system, the hydraulic transmission system, and the heating component 4 via signals. The control system can control the operation of the lubrication system and the hydraulic transmission system according to the various signals received, and can control whether the heating component 4 heats the oil tank 3.

[0108] Specifically, the interior of the oil tank 3 is equipped with a partition, which divides the interior of the oil tank 3 into a first oil tank 101 and a second oil tank 204. The first oil tank 101 supplies oil to the lubrication system, and the second oil tank 204 supplies oil to the hydraulic transmission system. This arrangement greatly saves the installation space and space occupied by the equipment.

[0109] Furthermore, the bottom of the first oil tank 101 and the second oil tank 204 are respectively provided with a first drain valve 110 and a second drain valve 210. The first drain valve 110 and the second drain valve 210 are preferably ball valves. The function of the drain ball valve is that when each piece of equipment needs to change the oil, this ball valve can completely drain the oil in the oil tank, which is convenient for changing the oil and indirectly helps to improve the service life of the equipment.

[0110] Furthermore, the first oil tank 101 is equipped with an electrically connected metal thermometer 102, a first air filter 106, and a first level gauge. The electrically connected metal thermometer 102 can display the oil temperature in the first oil tank 101 in real time. The second oil tank 204 is equipped with a heater 2041, a second level gauge 2042, a temperature relay 2043, a second air filter 2044, and an electrical control box 2045. The heater 2041 is preferably an electric heater. The electrical control box 2045 is electrically connected to the heater 2041 and the temperature relay 2043. When the temperature relay 2043 detects that the temperature in the second oil tank 204 has reached the set temperature... When the temperature relay 2043 detects that the temperature in the second oil tank 204 is lower than the set temperature, the electrical control box 2045 can control the heater 2041 to be powered on and heated, which allows the power station to work in cold conditions. When the lubricating oil needs to be heated, the heater 2041 heats the lubricating oil, and the heat of the lubricating oil is transferred to the first oil tank 101 through the partition, so that the hydraulic oil in both oil tanks can meet the requirements and keep the viscosity of the hydraulic oil within the working viscosity range of the hydraulic system. This reduces the number of heaters used, thereby reducing the production cost of the equipment.

[0111] like Figure 2As shown, the lubrication system includes a first hydraulic pump 103, a first hydraulic pump motor 105, an oil filter 107, a first check valve 109, a temperature sensor 1010, and a cooler 1011. The cooler 1011 is preferably an air-cooled cooler, and a cooler motor is mounted on it. The cooler motor drives a fan to rotate, thereby achieving air cooling of the cooler 1011. The control system is connected to the temperature sensor 1010 and the cooler motor. The oil filter 107 has a blockage alarm function and a bypass. The first hydraulic pump motor 105 and the first hydraulic pump 103 are driven by a coupling assembly 104. The first hydraulic pump 103 is connected to the first oil tank 101 via its inlet. The outlet of the first hydraulic pump 103 passes sequentially through the oil filter 107, the first check valve 109, and the cooler 1011 before entering the lubrication gearbox 1012. A temperature sensor 1010 is located in the oil circuit between the cooler 1011 and the lubrication gearbox 1012. The main function of the temperature sensor 1010 is to stop the cooler motor of the cooler 1011 when the temperature of the lubricating oil exiting the cooler 1011 is lower than the set temperature value. In this case, the cooler 1011 only acts as part of the lubrication pipeline and does not perform heat dissipation. Specifically, when the temperature sensor 1010 detects that the temperature of the lubricating oil exiting the cooler 1011 is lower than the set temperature value, the cooler motor is de-energized, and the cooler does not work. When the temperature sensor 1010 detects that the temperature of the lubricating oil exiting the cooler 1011 is higher than or equal to the set temperature value, the cooler motor is energized, the cooler 1011 works, and the lubricating oil is cooled.

[0112] The lubrication system also includes a first relief valve 1210 and a second relief valve 1220. The inlet of the first relief valve 1210 is connected to the oil passage between the first check valve 109 and the cooler 1011, and the outlet of the first relief valve 1210 is connected to the first oil tank 101. The function of the first relief valve 1210 is to regulate the maximum pressure in the lubrication system. The inlet of the second relief valve 1220 is connected to the oil passage between the lubrication gearbox 1012 and the cooler 1011, and the outlet of the second relief valve 1220 is connected to the first oil tank 101. The function of the second relief valve 1220 is to prevent excessive pressure in the lubrication gearbox 1012.

[0113] The lubrication system works by having the lubricating oil from the first hydraulic pump 103 pass sequentially through the oil filter 107, the first check valve 109, and the cooler 1011 before entering the lubrication gearbox 1012. Functionally, the lubrication system primarily achieves circulating lubrication and filtration / cooling of the lubricating oil. Simultaneously, the relief valve controls the maximum pressure achievable by the lubrication system, ensuring its safety. The most significant advantage of this design is that the lubricating oil immediately enters the cooler 1011 after passing through the oil filter 107, improving its cleanliness and lowering its temperature. This ensures that the oil entering the lubrication gearbox 1012 meets the required standards, thereby guaranteeing the safe operation of the gearbox.

[0114] It should be noted that, in order to increase the scalability of the lubrication system, multiple pressure testing connectors are also provided in the oil circuit. In one possible embodiment, a first pressure testing connector 181, a second pressure testing connector 182, a third pressure testing connector 183, and a fourth pressure testing connector 184 are respectively provided in the oil circuit between the first hydraulic pump 103 and the oil filter 107, the oil circuit between the oil filter 107 and the first check valve 109, the oil circuit between the first check valve 109 and the cooler 1011, and the oil circuit between the cooler 1011 and the lubrication gearbox 1012. In practical applications, pressure sensors can be connected to the pressure testing connectors as needed to realize the detection of local oil circuit pressure to meet specific needs.

[0115] Functionally, the lubrication system primarily serves to circulate lubricating oil and provide filtration and cooling. It also uses an overflow valve to control the maximum pressure the lubrication system can achieve, ensuring its pressure safety. The most significant advantage of this design is that the lubricating oil immediately enters the cooler after passing through the oil filter 107, improving its cleanliness and lowering its temperature. This ensures that the oil entering the gearbox meets the required standards, thereby guaranteeing the gearbox's operational safety.

[0116] like Figure 3 As shown, the hydraulic transmission system includes a dual hydraulic pump unit, a clamping device, a slewing device, and a lifting device. The hydraulic transmission system is mainly used to provide power to the stone crusher. The clamping device, slewing device, and lifting device are used to realize the three functions of clamping, slewing (with brake), and lifting, respectively.

[0117] Specifically, the dual hydraulic pump unit includes a dual hydraulic pump 205 and a dual hydraulic pump motor 206. The dual hydraulic pump motor 206 is connected to the dual hydraulic pump 205 for driving, enabling the dual hydraulic pump 205 to operate. The outlets of the dual hydraulic pump 205 are connected to the first branch 2001 and the second branch 2101 respectively, and can provide oil pressure P1 and oil pressure P2 to the first branch 2001 and the second branch 2101 respectively. The "one machine, two pumps" combination structure of the dual hydraulic pump 205 and the dual hydraulic pump motor 206 adopted in this utility model makes the hydraulic station structure compact and can effectively reduce the installation space.

[0118] The clamping device includes a first solenoid valve 2011, a second solenoid valve 2012, a third solenoid valve 2013, a fourth solenoid valve 2014, a second check valve 2031, a first accumulator 2021, a clamping assembly 2022, a first pressure relay 2023, a third relief valve 2131, and a first safety valve group. The first safety valve group includes a fourth relief valve 2132 and a first throttle valve 2141 arranged in parallel.

[0119] On the first branch 2001, a first solenoid valve 2011 and a second check valve 2031 are sequentially arranged from the outlet of the dual hydraulic pump 205. The first branch 2001, located between the first solenoid valve 2011 and the second check valve 2031, is connected to the seventh branch 007 via a second branch 002. A second solenoid valve 2012 is installed on the second branch 002. The end of the seventh branch 007 extends into the interior of the second oil tank 204. The right side of the first solenoid valve 2011 is connected to the seventh branch 007 via the first branch 001. The outlet of the second check valve 2031 connects to four branches: the third branch 003, the fourth branch 004, the fifth branch 005, and the sixth branch 006. The sixth branch 006 connects to the first pressure relay 2023, the fifth branch 005 connects to the clamping assembly 2022, and the fourth branch 004 connects to the first accumulator 2023. 21. A third solenoid valve 2013 is configured on the fourth branch 004, which is connected to the seventh branch 007 via the third branch 003. A fourth solenoid valve 2014 and a third relief valve 2131 are sequentially configured on the third branch 003. The fourth branch 004, located between the third solenoid valve 2013 and the first accumulator 2021, is connected to the seventh branch 007 via a first safety valve assembly. The first safety valve assembly includes a fourth relief valve 2132 and a first throttle valve 2141 arranged in parallel. Specifically, the principle by which the clamping assembly achieves the clamping function is as follows:

[0120] The dual hydraulic pump 205 provides power P1 to the first branch 2001, which is a clamping branch. When the first solenoid valve 2011 is de-energized, P1 is unloaded, and the hydraulic oil returns directly to the second oil tank 204 via the right position of the first solenoid valve 2011 and the first branch 001. The temperature relay 2043 and heater 2041 on the second oil tank 204 can ensure that the hydraulic transmission system can work normally in a low-temperature environment. When the first solenoid valve 2011 and the second solenoid valve 2012 are energized simultaneously, the hydraulic oil on the first branch 2001 is turned to the left by the first solenoid valve 2011, causing the clamping assembly 2022 to clamp while storing excess pressure energy in the first accumulator 2021. When the pressure of the clamping branch reaches the de-energizing pressure of the first solenoid valve 2011 and the second solenoid valve 2012 set by the first pressure relay 2023, the first solenoid valve 2011 and the second solenoid valve 2012 are automatically de-energized, P1 is unloaded again, and the second check valve 2031 isolates the pressure oil circuit from the first solenoid valve 2011. The first accumulator 2021 and the clamping assembly 2022 no longer fill with liquid. At this time, the two are interconnected, that is, the first accumulator 2021 provides power to the clamping assembly 2022. When the pressure of the first branch 2001 reaches the voltage pressure set by the first pressure relay 2023, the first solenoid valve 2011 and the second solenoid valve 2012 are energized, and P1 continues to fill the first accumulator 2021 with liquid to provide power to the clamping assembly 2022, and so on.

[0121] It should be noted that in the first branch 2001, when the dual hydraulic pump motor 206 starts, regardless of whether the first solenoid valve 2011 is energized, the third solenoid valve 2013 and the fourth solenoid valve 2014 are not energized. The function of the fourth relief valve 2132 is to limit the maximum pressure that the first accumulator 2021 can reach. The function of the first throttle valve 2141 is that when the fourth relief valve 2132 fails, the first throttle valve 2141 can be manually switched to temporarily act as a safety valve to completely unload the oil in this branch.

[0122] When the dual hydraulic pump motor 206 is de-energized, both the third solenoid valve 2013 and the fourth solenoid valve 2014 are energized. At this time, the function of the third solenoid valve 2013 is to isolate the first accumulator 2021 from the clamping assembly 2022 and to allow the first accumulator 2021 to maintain pressure independently. The function of the fourth solenoid valve 2014 is to disconnect the first accumulator 2021 from the clamping assembly 2022 when the third solenoid valve 2013 is energized. At this time, the clamping assembly 2022 still maintains the original clamping pressure. When the fourth solenoid valve 2014 is energized, it can reduce the pressure to the lower pressure (15 bar) set by the third relief valve 2131. By setting the third relief valve 2131, the maximum pressure of the lubrication system is controllable.

[0123] Specifically, the first accumulator 2021 in the clamping circuit of the hydraulic transmission system functions to store energy and maintain pressure. The fourth solenoid valve 2014 and the third relief valve 2131 work together to maintain the branch pressure at 15 bar in the non-clamping state.

[0124] like Figure 3 As shown, the rotary device includes a shuttle valve 2019, a high-pressure filter 2102, a fifth solenoid valve 2153, a sixth solenoid valve 2154, and a hydraulic motor 2024. The outlet of the double hydraulic pump 205 is connected to the second branch 2101. The high-pressure filter 2102 and the fifth solenoid valve 2153 are sequentially arranged on the second branch 2101 along the direction of hydraulic oil flow. The outlet of the fifth solenoid valve 2153 is connected to the sixth solenoid valve 2154 via the eleventh branch 024. The high-pressure filter 2102 and the fifth solenoid valve 2024 are connected to each other. The second branch 2101 between solenoid valves 2153 is connected to the left position of the sixth solenoid valve 2154 via the ninth branch 022. The right position of the sixth solenoid valve 2154 is connected to the P port of the hydraulic motor 2024, and the left position of the sixth solenoid valve 2154 is connected to the T port of the hydraulic motor 2024. The brake can be released by entering the brake piston of the hydraulic motor 2024 through the shuttle valve 2019 via either the P port or the T port. The right position of the fifth solenoid valve 2153 is connected to the seventh branch 007.

[0125] The principle behind the slewing function is as follows:

[0126] The dual hydraulic pump 205 provides oil pressure P2 to the second branch 2101. When the mobile device (not shown in the figure) connected to the hydraulic motor 2024 needs to rotate in the forward direction, the fifth solenoid valve 2153 is energized in the left position and de-energized in the right position, and the sixth solenoid valve 2154 is energized in the right position and de-energized in the left position. The pressurized oil enters the P port of the hydraulic motor 2024 and enters the brake piston of the hydraulic motor 2024 through the shuttle valve 2019, releasing the brake. The hydraulic motor 2024 rotates in the forward direction, thereby driving the crusher to rotate in the forward direction. When the crusher connected to the hydraulic motor 2024 needs to rotate in reverse, the sixth solenoid valve 2154 is energized in the left position and de-energized in the right position. Pressure oil enters the T-port of the hydraulic motor 2024 and simultaneously enters the brake piston of the hydraulic motor 2024 through the shuttle valve 2019, releasing the brake. The hydraulic motor 2024 then rotates in reverse, thereby driving the crusher to rotate in reverse. When the crusher is not needed, both sides of the sixth solenoid valve 2154 are de-energized, the valve core is in the neutral position, and the hydraulic motor 2024 stops and is in a braking state. When P2 unloading is required, the fifth solenoid valve 2153 is de-energized in the left position and energized in the right position. Hydraulic oil in the second branch 2101 returns directly to the second oil tank 204 via the right position of the fifth solenoid valve 2153 and the seventh branch 007. In this invention, the rotation device controls the forward and reverse rotation of the hydraulic motor 2024 through the sixth solenoid valve 2154, while the shuttle valve 2019 ensures that the hydraulic motor 2024 is in a released braking state in any rotating state and in a braking state when not rotating.

[0127] like Figure 3As shown, the lifting device includes a hydraulic check valve 2020, a second accumulator 2025, a lifting cylinder 2026, a second pressure relay 2027, a seventh solenoid valve 2155, a sixth relief valve 2134, a second safety valve assembly, and a fifth solenoid valve 2153. The outlet of the dual hydraulic pump 205 is connected to the second branch 2101. A high-pressure filter 2102 and the fifth solenoid valve 2153 are sequentially arranged on the second branch 2101 along the direction of hydraulic oil flow. The outlet of the fifth solenoid valve 2153... The 12th branch 025 is connected to the right position of the 7th solenoid valve 2155. The 9th branch 022 on the second branch 2101 between the high-pressure filter 2102 and the 5th solenoid valve 2153 connects to the left position of the 7th solenoid valve 2155. The right position of the 7th solenoid valve 2155 is connected to the lifting cylinder 2026 via the hydraulic check valve 2020. The lifting cylinder 2026 is connected to the 13th branch 026 via the 6th relief valve 2134. The 13th branch 026 is connected to the 7th branch 007. The hydraulic check valve 2020 and the lifting cylinder 2026 are connected to the second accumulator 2025, the second pressure relay 2027, and the second safety valve group via the 14th branch 027. The second safety valve group is connected to the 7th branch 007 via the 15th branch 028. The second safety valve group includes the 5th relief valve 2133 and the 2142 arranged in parallel. Specifically, the lifting device achieves its lifting function on the following principle:

[0128] The dual hydraulic pump 205 provides oil pressure P2 to the second branch 2101. When the fifth solenoid valve 2153 is energized in its left position, the seventh solenoid valve 2155 is energized in its right position and de-energized in its left position, causing the lifting cylinder 2026 to extend. Conversely, when the seventh solenoid valve 2155 is energized in its left position and de-energized in its right position, the lifting cylinder 2026 retracts. Therefore, the function of the seventh solenoid valve 2155 is to control the extension or retraction of the lifting cylinder 2026. When the lifting cylinder 2026 needs to be stabilized in a certain position, both the fifth and seventh solenoid valves 2153 and 2155 are de-energized. At this time, the pressure in the rod chamber of the lifting cylinder 2026 is maintained by the hydraulically controlled check valve 2020, which allows the rod chamber of the lifting cylinder 2026 to be maintained at a certain pressure state for an extended period. The second accumulator 2025 absorbs pressure vibrations caused by the external load on the lifting cylinder 2026, improving the stability of the lifting cylinder 2026 during lifting. The sixth relief valve 2134 sets the maximum pressure of this branch when the lifting cylinder retracts. The fifth relief valve 2133 prevents excessive external load vibrations on the lifting cylinder 2026 from causing excessive internal system pressure after the seventh solenoid valve 2155 is de-energized. The second throttle valve 2142 is an unloading throttle valve, its function being to unload the lifting cylinder 2026 after the seventh solenoid valve 2155 is de-energized. The rod chamber is manually depressurized. The function of the second pressure relay 2027 is that when the lifting cylinder 2026 retracts, when the pressure in the rod chamber reaches the pressure set by the second pressure relay 2027 for the right-side de-energization of the seventh solenoid valve 2155, the seventh solenoid valve 2155 is de-energized, the lifting cylinder 2026 is stabilized, and the rod chamber maintains pressure. After maintaining pressure, when the pressure reaches the pressure set by the second pressure relay 2027 for the right-side energization of the seventh solenoid valve 2155, the seventh solenoid valve 2155 is energized, and the oil pressure P2 in the second branch 2101 is used to pressurize this branch, and so on.

[0129] The energy-saving feature of the hydraulic transmission system in this utility model is reflected in the fact that when no pressure oil is needed in each branch of the hydraulic system, the second solenoid valve 2012 and the fifth solenoid valve 2153 are de-energized. The hydraulic oil from the hydraulic double pump 205 flows directly back to the second oil tank 204 through the second solenoid valve 2012 and the fifth solenoid valve 2153 without overflowing through the relief valve. During this process, the system pressure is always zero, which greatly reduces the heat generation of the system.

[0130] It should be noted that the hydraulic power of both the slewing device and the lifting device is provided by the large displacement pump in the double hydraulic pump 205, which in turn provides pressure P2. If the fifth solenoid valve 2153 is energized, the fifth solenoid valve 2153 can work normally. If the fifth solenoid valve 2153 is de-energized, P2 is in an unloaded state.

[0131] Specifically, the first pressure relay 2023 and the hydraulic motor 2024 are each set with two pressure points. When the pressure of the first pressure relay 2023 reaches the rising point, the second solenoid valve 2012 is de-energized and the first solenoid valve 2011 is energized. When the pressure of the second pressure relay 2027 reaches the rising point, the seventh solenoid valve 2155 is de-energized in the right position, and the rod chamber of the lifting cylinder 2026 maintains pressure. When the pressure reaches the rising point, the seventh solenoid valve 2155 is energized in the right position to supplement the pressure in the rod chamber of the lifting cylinder 2026.
