Description

Technical Field

[0001] This invention belongs to the field of hydraulic oil tank technology, specifically a large hydraulic oil tank that is resistant to tilting and leakage. Background Technology

[0002] Large hydraulic oil tanks are widely used in outdoor operating equipment such as engineering vehicles and mining machinery. Their core function is to store hydraulic oil and provide a stable oil supply for the hydraulic system. The breathing function is the key to the normal operation of the hydraulic oil tank. It is necessary to achieve gas exchange between the inside of the oil tank and the outside through the breathing channel to maintain the pressure balance inside the oil tank and avoid problems such as deformation of the oil tank body and failure of the hydraulic system due to excessively high or low pressure.

[0003] For example, a dustproof, heat-absorbing, and energy-storing hydraulic oil tank with publication number CN215634025U includes a tank body, a connecting column connected to the top of the tank body, a rotating column connected to the top of the connecting column, a cover plate connected to the top of the rotating column, a filter plate connected to the bottom of the cover plate, a water pump connected to the bottom of the inner wall of the tank, a suction pipe connected to one end of the water pump, an oil outlet pipe connected to the other end of the water pump, a heat-absorbing energy storage device connected to the bottom of the inner wall of the tank on the side of the water pump, and a temperature controller connected to one side of the inner wall of the tank. In this utility model, by setting the filter plate and the cover plate, the hydraulic oil tank can effectively isolate external dust and improve the quality of hydraulic oil. By setting the temperature controller and the heat-absorbing energy storage device, the heat generated during the operation of the hydraulic system can be absorbed and converted, and the temperature inside the oil tank can be maintained to avoid affecting the normal operation of the hydraulic system.

[0004] While the above solutions can absorb and convert the heat generated during the operation of the hydraulic system and maintain the temperature inside the oil tank, the current large hydraulic oil tanks have a simple breather valve structure in their breathing channels. When engineering vehicles in complex outdoor working conditions are traveling on bumps, the oil level in the vehicle's tank will shift due to tilting. When the tilt angle exceeds the safe range, the hydraulic oil is prone to overflow and leak from the breathing channel, which not only wastes hydraulic oil but also causes equipment failure. In severe cases, the leaked oil may even pose a safety hazard because it is flammable. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a large hydraulic oil tank that prevents tilting and leakage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a large hydraulic oil tank with anti-tilt leakage, comprising an oil tank body equipped with a breather port, wherein one end of the breather port extending into the oil tank body is fixedly connected to an internal pipe, and a breather valve body is assembled between the breather port and the internal pipe, and further comprising: Two assembly rings are spaced apart along a vertical direction, and both are located inside the internal pipe; A vertical blocking rod unit is installed in the upper assembly ring frame. The vertical blocking rod unit includes a fixed ring frame, the inner end of which is slidably connected to a movable main rod. The upper end of the movable main rod is fixedly connected to a sealing plug that cooperates with the breathing valve body. The outer side of the middle part of the movable main rod is fixedly connected to an anti-fall limit ring. A gravity swing unit is installed in the assembly frame located below. The gravity swing unit includes a fixed frame two. The inner side of the fixed frame two is provided with an arc-shaped slot. A universal ball is provided at the inner end of the arc-shaped slot. An inverted conical hollow protrusion is fixedly connected to the upper end of the universal ball. A vertical connecting rod is fixedly connected to the lower end of the universal ball. A counterweight column is fixedly connected to the lower end of the vertical connecting rod.

[0007] Preferably, the end of the breathing valve body near the internal pipe has an air hole, and the diameter of the sealing plug matches the inner diameter of the air hole.

[0008] Preferably, the anti-fall limiting ring is located above the first fixed ring frame, and the diameter of the anti-fall limiting ring is larger than the diameter of the first fixed ring frame to limit the sliding stroke of the movable main rod and prevent it from falling out of the first fixed ring frame.

[0009] Preferably, the arc-shaped slot and the universal ball are connected by a universal rotation connection to enable the gravity swing unit to swing flexibly in multiple directions and adapt to the tilt state of the oil tank body at different angles.

[0010] Preferably, the lower end of the movable main rod is fixedly connected to an arc-shaped spherical surface, and the upper end of the inverted conical hollow protrusion is fixedly connected to an arc-shaped edge for increasing the contact area with the arc-shaped spherical surface.

[0011] Preferably, a disassembly and assembly component unit is provided between the two assembly rings and the internal pipe to enable quick disassembly and assembly of the assembly rings and the internal pipe. The disassembly and assembly component unit includes a threaded assembly surface formed on the inner wall of the internal pipe, and a threaded mounting cylinder is fixedly connected to one end of the two assembly rings near the threaded assembly surface.

[0012] Preferably, the inner sidewalls of the two assembly ring frames are respectively fixedly connected with two sets of transverse reinforcing ribs, and the two sets of transverse reinforcing ribs are respectively fixedly connected to the corresponding fixed ring frame one and fixed ring frame two to enhance the installation stability of fixed ring frame one and fixed ring frame two.

[0013] Preferably, multiple vertical connecting ribs are fixedly connected to the vertical sides of the two assembly ring frames that are close to each other. The multiple vertical connecting ribs are arranged in a ring at equal intervals to connect the two assembly ring frames to form an integral load-bearing structure.

[0014] Preferably, the contact surface between the sealing plug and the breather valve body is made of oil-resistant rubber to improve the fit and sealing performance with the vent of the breather valve body.

[0015] Preferably, the counterweight column is a solid cylindrical structure used to ensure sufficient gravity counterweight, and the counterweight column is made of cast iron.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the cooperative structure of a gravity swing unit and a vertical plug unit, ensures that the sealing plug is separated from the vent when the oil tank body is horizontal, ensuring that the oil tank body can breathe normally to maintain internal pressure balance. When the oil tank body is tilted to a safe angle or higher, the sealing action is automatically triggered, realizing the intelligent linkage between the oil tank body's breathing function and leakage prevention protection. This effectively solves the safety problem of hydraulic oil easily leaking from the breathing channel when the existing oil tank body is tilted, and improves the safety of the oil tank body in complex outdoor working conditions. This invention effectively improves the linkage transmission effect between the vertical plug rod unit and the gravity swing unit by optimizing the matching structure of the arc-shaped spherical surface and the arc-shaped edge. The precise matching of the curvature of the arc-shaped spherical surface and the arc-shaped edge allows for stable surface contact when they come into contact, replacing the traditional point contact method. This not only significantly increases the contact area and reduces local force concentration, effectively reducing wear at the contact points of the components, but also allows the thrust of the inverted conical hollow protrusion to be evenly transmitted to the moving main rod, enabling the sealing plug to be accurately aligned with the air hole of the breather valve body, improving the sealing performance. In addition, the arc-shaped edge adopts a rounded corner transition design, which can avoid sharp edges scratching the arc-shaped spherical surface, further optimizing the reliability of the components and ensuring the long-term stable operation of the linkage structure. This invention effectively strengthens the overall structural strength and load-bearing capacity of the assembly ring by setting horizontal reinforcing ribs and vertical connecting ribs inside the assembly ring. Furthermore, the threaded connection method of the assembly and disassembly component units enables rapid assembly and disassembly, which not only ensures the operational stability of the internal structure but also significantly reduces the operational difficulty of later inspection and maintenance.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 6As shown, this invention provides a large hydraulic oil tank with anti-tilt leakage, including an oil tank body 1 with a breather 2. The breather 2 is a channel connecting the oil tank body 1 to the outside. One end of the breather 2 extending into the oil tank body 1 is fixedly connected to an internal pipe 3. A breather valve body 4 is assembled between the breather 2 and the internal pipe 3. The breather valve body 4 is used to control the breathing of the oil tank body 1, ensuring the internal pressure balance of the oil tank body 1 and preventing damage to the oil tank body 1 due to excessively high or low pressure. It also includes two mounting rings 5 ​​arranged vertically at intervals, both of which are set in the internal pipe 3. A vertical plug rod unit 6 is installed in the upper mounting ring 5. The vertical plug rod unit 6 includes a fixed ring 600. The inner end of the fixed ring 600 is slidably connected to a movable main rod 601. The upper end of the movable main rod 601 is fixedly connected to a sealing plug 602 that cooperates with the breather valve body 4. The middle outer side of the movable main rod 601 is fixed. A gravity swing unit 7 is installed in the lower assembly frame 5, connected to a fall arrestor limit ring 603. The gravity swing unit 7 includes a second fixed frame 700, with an arc-shaped slot 701 on its inner side. A universal ball 702 is located at the inner end of the arc-shaped slot 701. An inverted conical hollow protrusion 703 is fixedly connected to the upper end of the universal ball 702, and a vertical connecting rod 705 is fixedly connected to the lower end of the universal ball 702. The lower end of the vertical connecting rod 705... The end is fixedly connected to a counterweight column 706, which is used to drive the universal ball 702 to always maintain a vertical downward posture by its own weight, so as to effectively trigger the linkage sealing action when the oil tank body 1 is tilted. The contact surface between the sealing plug 602 and the breather valve body 4 is made of oil-resistant rubber material, which is used to improve the fit and sealing of the breather valve body 4 vent. The counterweight column 706 is a solid cylindrical structure to ensure sufficient gravity counterweight, and the counterweight column 706 is made of cast iron.

[0021] Using the above solution: When the oil tank body 1 tilts due to external forces until it exceeds the safe angle, hydraulic oil is prone to leak from the breathing channel. To address this problem, the present invention achieves automatic sealing through gravity drive. The linkage between the gravity swing unit 7 and the vertical plug rod unit 6 can realize the switching between the anti-leakage and normal breathing scenarios. When the oil tank body 1 returns to the horizontal state, the leakage risk is eliminated. At this time, it is necessary to restore the normal breathing function of the oil tank body 1. Therefore, the counterweight column 706 drives the vertical connecting rod 705 and the universal ball 702 to reset. The thrust of the inverted conical hollow protrusion 703 on the arc-shaped spherical surface 604 disappears. The movable main rod 601 slides down and resets along the inner side of the fixed ring 600 under its own gravity. The sealing plug 602 separates from the air hole of the breather valve body 4, the air hole reopens, and the oil tank body 1 restores its normal breathing function.

[0022] like Figures 1 to 6As shown, the breathing valve body 4 has an air hole at one end near the internal pipe 3. The diameter of the sealing plug 602 matches the inner diameter of the air hole. The anti-fall limit ring 603 is located above the fixed frame 600, and the diameter of the anti-fall limit ring 603 is larger than the diameter of the fixed frame 600 to limit the sliding stroke of the movable main rod 601 and prevent it from falling out of the fixed frame 600. The arc-shaped slot 701 and the universal ball 702 are connected by a universal rotation connection to realize the multi-directional flexible swing of the gravity swing unit 7 and adapt to the tilt state of the oil tank body 1 at different angles. The lower end of the movable main rod 601 is fixedly connected to the arc-shaped spherical surface 604, and the upper end of the inverted conical hollow protrusion 703 is fixedly connected to the arc-shaped edge 704 to increase the contact area with the arc-shaped spherical surface 604.

[0023] The above solution employs the following: the inner wall of the arc-shaped slot 701 is smoothly polished, which reduces the frictional resistance when the universal ball 702 rotates, ensuring smooth and flexible rotation. Simultaneously, the arc design of the arc-shaped slot 701 conforms to the rotation trajectory of the universal ball 702, providing sufficient rotation space while limiting excessive rotation and preventing interference between the vertical connecting rod 705 and the internal pipe 3 due to excessive rotation angle. The arc curvature of the arc-shaped spherical surface 604 precisely matches the curvature of the arc-shaped edge 704, ensuring surface contact rather than point contact. This increases the contact area, reduces wear caused by concentrated local forces, and allows the thrust of the inverted conical hollow protrusion 703 to be evenly transmitted to the movable main rod 601, preventing force deviation in the movable main rod 601 and resulting in misalignment of the sealing. Furthermore, the arc-shaped edge 704 uses a rounded corner transition design, preventing sharp edges from scratching the arc-shaped spherical surface 604 and further extending the service life of the components.

[0024] like Figures 1 to 6 As shown, a disassembly and assembly component unit 8 is provided between the two assembly rings 5 ​​and the internal pipe 3 to enable quick disassembly and assembly of the assembly rings 5 ​​and the internal pipe 3. The disassembly and assembly component unit 8 includes a threaded assembly surface 800 opened on the inner side wall of the internal pipe 3, and a threaded mounting cylinder 801 is fixedly connected to one end of the two assembly rings 5 ​​near the threaded assembly surface 800.

[0025] The above solution is adopted: the assembly and disassembly of component unit 8 is carried out by a threaded connection method in which the threaded assembly surface 800 and the threaded mounting cylinder 801 cooperate with each other. By rotating the assembly ring frame 5, the threaded mounting cylinder 801 can be driven to rotate in or out along the threaded assembly surface 800, thereby quickly realizing the assembly and disassembly operations of the assembly ring frame 5 and the internal pipe 3, which solves the problems of cumbersome disassembly and assembly and high maintenance costs of the existing structure.

[0026] like Figures 1 to 6As shown, two sets of transverse reinforcing ribs 501 are fixedly connected to the inner sidewalls of the two assembly ring frames 5 respectively. The two sets of transverse reinforcing ribs 501 are fixedly connected to the corresponding fixed ring frame 1 600 and fixed ring frame 2 700 respectively, which are used to enhance the installation stability of fixed ring frame 1 600 and fixed ring frame 2 700. Multiple vertical connecting ribs 502 are fixedly connected to the vertical side of the two assembly ring frames 5 that are close to each other. The multiple vertical connecting ribs 502 are arranged in a ring at equal intervals to connect the two assembly ring frames 5 to form an integral load-bearing structure.

[0027] The above-mentioned solution is adopted to further improve structural stability. The assembly frame 5 is equipped with a transverse reinforcing rib 501, which is fixedly connected to the first fixed frame 600 and the second fixed frame 700. This can enhance the installation stability of the first fixed frame 600 and the second fixed frame 700, and prevent the fixed frame from loosening and shifting due to long-term vibration of the oil tank body 1, thus affecting the linkage accuracy. The vertical connecting ribs 502, which are arranged in a ring at equal intervals, can connect the two assembly frames 5 and form an integral load-bearing structure, improving the overall strength of the assembly frame 5. This solves the problem of structural weakness caused by the two assembly frames 5 being independent, and is suitable for the long-term operation requirements of the oil tank body 1.

[0028] Working principle and usage process of this invention: In the initial state, the tank body 1 remains horizontal. The counterweight column 706, due to the gravity of its solid cast iron cylindrical structure, drives the vertical connecting rod 705 to remain vertical. The vertical connecting rod 705 drives the universal ball 702 to maintain a vertical position within the arc-shaped slot 701 of the fixed frame 2 700. The inverted conical hollow protrusion 703 at the upper end of the universal ball 702 is in contact with the arc-shaped spherical surface 604 at the lower end of the movable main rod 601 through the arc-shaped edge 704. At this time, the movable main rod 601 is in a natural sliding state within the fixed frame 1 600. The sealing plug 602 does not block the air hole on the breather valve body 4. The tank body 1 can breathe normally through the air hole in the breather valve body 4 in the breather port 2, ensuring the internal pressure balance of the tank body 1. When the fuel tank body 1 tilts due to external forces until it exceeds the safe angle, the counterweight column 706, due to its own weight, drives the vertical connecting rod 705 to swing synchronously. The vertical connecting rod 705 drives the universal ball 702 to rotate omnidirectionally within the arc-shaped slot 701. The arc-shaped slot 701 and the universal ball 702 are connected for omnidirectional rotation, enabling the gravity swing unit 7 to swing flexibly in multiple directions, adapting to different tilt angles of the fuel tank body 1. When the universal ball 702 swings, it drives the inverted conical hollow protrusion 703 to tilt synchronously. The inverted conical hollow protrusion 703 pushes the arc-shaped spherical surface 60 through the arc-shaped edge 704. 4. Moving upward, the arc-shaped edge 704 can increase the contact area with the arc-shaped spherical surface 604, improving transmission stability. When the arc-shaped spherical surface 604 is pushed upward, it drives the movable main rod 601 to slide upward along the inner side of the fixed ring frame 600. When the movable main rod 601 slides upward, it drives the sealing plug 602 to rise synchronously until the sealing plug 602 is precisely fitted with the air hole of the breather valve body 4. The contact surface between the sealing plug 602 and the breather valve body 4 is made of oil-resistant rubber material, which can improve the fit and sealing performance, effectively block the air hole, and prevent the hydraulic oil in the oil tank body 1 from leaking from the breather port 2 connected to the air hole. When the tank body 1 returns to a horizontal state, the counterweight column 706 drives the vertical connecting rod 705 and the universal ball 702 to reset. The thrust of the inverted conical hollow protrusion 703 on the arc-shaped spherical surface 604 disappears. The movable main rod 601 slides down and resets along the inner side of the fixed frame 600 under its own weight. The sealing plug 602 separates from the air hole of the breather valve body 4, the air hole reopens, and the tank body 1 resumes normal breathing function. The anti-fall limit ring 603 is located above the fixed frame 600 and its diameter is larger than that of the fixed frame 600. It can limit the sliding stroke of the movable main rod 601 when it falls back and prevent the movable main rod 601 from falling out of the fixed frame 600. The assembly ring frame 5 is also equipped with transverse reinforcing ribs 501 that are fixedly connected to the first fixed ring frame 600 and the second fixed ring frame 700, which can enhance the installation stability of the first fixed ring frame 600 and the second fixed ring frame 700. The vertical connecting ribs 502, which are arranged in a ring shape at equal intervals, can connect the two assembly ring frames 5 and form an integral load-bearing structure, thereby improving the overall strength of the assembly ring frame 5. Furthermore, this solution includes a disassembly and assembly unit 8, which uses a threaded connection between the threaded assembly surface 800 and the threaded mounting cylinder 801. Rotating the assembly ring 5 will cause the threaded mounting cylinder 801 to rotate in or out along the threaded assembly surface 800, thereby quickly realizing the disassembly and assembly of the assembly ring 5 and the internal pipe 3. This significantly reduces the difficulty of subsequent inspection, maintenance, and replacement of various components such as the vertical plug rod unit 6 and the gravity swing unit 7, and improves operation and maintenance efficiency.
