Description

Technical Field

[0001] This utility model relates to the field of hydraulic station technology, and in particular to a hydraulic station with an oil tank frame. Background Technology

[0002] In industrial production systems, the tank-frame hydraulic power unit serves as a core hub for power transmission, widely used in key areas such as machine tool processing, metallurgical forging, and construction machinery. Its gate structure, as the interface between the equipment and the external environment, not only protects internal components and isolates them from dust and impurities, but also directly determines the convenience of maintenance and the safety of equipment operation, making it a crucial and indispensable aspect of hydraulic power unit structural design. However, current traditional tank-frame hydraulic power units generally suffer from a problem of "few gates and limited coverage," a design flaw that has become a significant bottleneck restricting equipment performance optimization and operational efficiency improvement.

[0003] From the perspective of actual maintenance needs, traditional hydraulic stations with a tank-body frame often only cover the core components (such as the main motor and control panel) on the front or one side of the equipment due to the limited number of doors. They lack corresponding access doors for critical components located at the rear, sides, and deep inside the equipment, such as the tank body, filters, and oil line interfaces. When these hidden components need maintenance, workers have to resort to cumbersome methods such as disassembling the equipment casing and removing adjacent parts to obtain operating space. This not only prolongs maintenance time but also may cause scratches on the equipment surface during disassembly, or result in incomplete maintenance due to limited operating space, leaving potential risks of oil line blockage, component wear, and other malfunctions. Especially in scenarios with continuous production line operation, excessively long maintenance times can directly affect production progress and cause unnecessary economic losses.

[0004] Therefore, it is necessary to design a tank frame hydraulic station to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic station with a tank frame. This utility model increases the number of doors, thereby facilitating the inspection and maintenance of various components of the hydraulic station and improving the efficiency of inspection and maintenance. At the same time, it facilitates the installation and disassembly of the diamond mesh, preventing excessive accumulation of fibrous material on the diamond mesh from affecting the heat dissipation effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hydraulic station with an oil tank frame includes a frame. Multiple vertical rods are installed on the inner bottom of the frame, and each of the vertical rods is rotatably connected to a front door via hinges. Side doors are rotatably connected to the left and right sides of the frame via hinges. A top plate is fixedly connected to the upper end of the frame. Multiple main motor mounting plates and multiple oil tank bodies are installed on the inner bottom of the frame. A first diamond-shaped mesh is installed on each of the front doors located on the front side, and a second diamond-shaped mesh is installed on each of the top plates. Two filter inspection covers are installed on the top plate located on the left side.

[0008] Preferably, a wash window cover is installed on both the front door located at the rear and the side door located on the right side.

[0009] Preferably, the first diamond mesh and the front door are connected by a connecting assembly, which includes two fixed plates fixedly connected to the front door. Each of the two fixed plates has a sliding groove on its adjacent side, and two sliders are slidably connected in each of the two sliding grooves. Each of the two fixed plates has a pressure block on its adjacent side, and each pressure block is fixedly connected to a corresponding slider. Each slider is elastically connected to the inner wall of the sliding groove by a spring. Each pair of mating pressure blocks has a pressure rod fixedly connected to the opposite sides.

[0010] Preferably, two fixing blocks are fixedly connected to the front door, and a threaded rod is rotatably connected to the adjacent sides of the two fixing blocks. Two moving blocks are threadedly connected to the threaded rod, and connecting plates are fixedly connected to the left and right sides of the two moving blocks. A knob is fixedly connected to the upper end of the threaded rod.

[0011] Preferably, each pair of mating pressure rods has an L-shaped block fixedly connected to its adjacent sides. Each L-shaped block consists of a vertical part and a horizontal part. Each horizontal part of the L-shaped block is fixedly connected to a T-shaped positioning rod. The connecting plate has a through-hole, and each positioning rod passes through the corresponding positioning rod.

[0012] Preferably, the upper end surfaces of the pressure block and the pressure rod are both arc surfaces.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with existing technologies, this device optimizes the number of doors and comprehensively upgrades the coverage by adding rotatable front doors on the front and rear sides of the frame and rotatable side doors on the left and right sides. The doors can be opened directly in the corresponding directions, allowing staff to quickly access all components to be maintained without additional disassembly, significantly reducing maintenance time and effectively improving maintenance efficiency. It also avoids problems such as scratches on the equipment surface and incomplete maintenance during disassembly, ensuring the stability of equipment operation.

[0015] 2. Compared with existing technologies, this device, based on a multi-door design, incorporates a first diamond-shaped mesh on the front door and a second diamond-shaped mesh on the top plate to construct a heat dissipation and protection system of "multi-channel ventilation + precise protection." Through the diamond-shaped mesh structure on the multiple doors, while ensuring ventilation area, the mesh density of the diamond-shaped mesh blocks external dust and impurities from entering.

[0016] 3. Compared with existing technologies, this device facilitates the installation and removal of the diamond mesh. When the diamond mesh accumulates fibrous material and affects heat dissipation, the staff can quickly remove the diamond mesh for cleaning by rotating the knob. After cleaning, it can be directly pressed and installed, avoiding potential problems such as shortened hydraulic oil life and decreased component sealing performance caused by obstructed heat dissipation, thus extending the overall service life of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4A hydraulic station with a tank frame includes a frame 1, which serves as the load-bearing foundation for the entire equipment. The frame 1 is constructed of welded I-beams to ensure structural strength and has an overall rectangular frame structure. Multiple vertical rods are installed on the inner bottom of the frame 1, each connected to a front door 4 via hinges. Side doors 2 are connected to the left and right sides of the frame 1 via hinges. One side of each hinge is welded to a vertical rod, and the other side is bolted to the front door 4, allowing the front door 4 to rotate 180° around the vertical rod for full opening. The side doors 2 are connected in the same way as the front doors 4, ensuring they can also be opened flexibly to their maximum angle for convenient side operation. A top plate is fixedly connected to the upper end of the frame 1. 6. Multiple main motor mounting plates 10 and multiple oil tank bodies 9 are installed on the inner bottom of the frame 1. The main motor mounting plates 10 have multiple oblong holes for mounting and fixing different models of main motors. They are detachably connected to the bottom of the frame 1 by bolts. The oil tank bodies 9 are fixed to the inner bottom of the frame 1 by brackets. The oil outlet and return port of the oil tank bodies 9 face inward to facilitate connection with hydraulic lines. Multiple front doors 4 on the front side are equipped with first diamond mesh 5, multiple top plates 6 are equipped with second diamond mesh 7, two filter maintenance covers 8 are installed on the top plate 6 on the left side, and cleaning window covers 3 are installed on the front door 4 on the rear side and the side door 2 on the right side.

[0024] The first diamond mesh 5 and the front door 4 are connected by a connecting assembly, which includes two fixed plates 16 fixedly connected to the front door 4. Each of the two fixed plates 16 has a groove 18 on its adjacent side, and two sliders are slidably connected in each of the two grooves 18. Each of the two fixed plates 16 has a pressure block 17 on its adjacent side, and each pressure block 17 is fixedly connected to the corresponding slider. Each slider is elastically connected to the inner wall of the groove 18 by a spring 19. Each pair of mating pressure blocks 17 has a pressure rod 15 fixedly connected to their opposite sides. The pressure rod 15 is integrally formed with the pressure block 17 to enhance the structural strength. The upper end surfaces of the pressure block 17 and the pressure rod 15 are both arc surfaces. The arc surface can guide the first diamond mesh 5 to smoothly squeeze the pressure block 17 and the pressure rod 15 during installation, reducing installation resistance.

[0025] The front door 4 has two fixed blocks 11, and the adjacent sides of the two fixed blocks 11 are rotatably connected to a threaded rod 13. The threaded rod 13 is a two-way screw, and the threaded rod 13 is threaded with two moving blocks 21. The left and right sides of the two moving blocks 21 are fixedly connected to connecting plates 14. The upper end of the threaded rod 13 is fixedly connected to a knob 12. The adjacent sides of every two mating pressure rods 15 are fixedly connected to L-shaped blocks 22. Each L-shaped block 22 consists of a vertical part and a horizontal part, and the vertical part is connected to the pressure rod 15. The horizontal part extends towards the connecting plate 14. Each L-shaped block 22 is fixedly connected to a T-shaped positioning rod 20 on its horizontal part. The positioning rod 20 is welded to the L-shaped block 22. Its vertical section passes through the through-hole, and its horizontal section can limit the connecting plate 14, so that the movement of the two moving blocks 21 in opposite directions will drive the L-shaped block 22 to move synchronously. However, in the design of installing the first diamond mesh 5, the movement of the pressure rod 15 will not drive the connecting plate 14 to move. The connecting plate 14 is provided with a through-hole, and each positioning rod 20 passes through the corresponding positioning rod 20.

[0026] The functional principle of this utility model can be explained through the following operation: In terms of door opening and maintenance adaptation, when it is necessary to inspect different parts of the hydraulic station, the operator can directly open the front door 4 on the front and rear sides of the frame 1 and the side door 2 on the left and right sides by rotating the hinge structure. When the front door 4 is opened, the motor on the front main motor mounting plate 10 and the related pipeline inside the front door 4 can be directly accessed; when the side door 2 is opened, the oil tank body 9 and oil circuit interface on the left and right sides can be quickly accessed; when the rear front door 4 is opened, the rear-end components and oil tank body 9 can be inspected inside the equipment; the operator can open the cleaning window cover 3 by using the buckle or bolt disassembly structure, and can quickly check or simply clean the internal parts (such as oil level observation of oil tank body 9 and pipeline joint inspection) without opening the entire door; for the two filter maintenance cover plates 8 on the top plate 6, the filter element can be replaced and the inside cleaned by directly removing the filter maintenance cover plate 8, avoiding the cumbersome operation of removing a large area of ​​the top plate 6 required by the traditional structure, and further improving the efficiency of local maintenance.

[0027] When the first diamond mesh 5 needs to be installed, simply align the side of the first diamond mesh 5 with the mounting opening on the front door 4 and press it in. Since the upper ends of the pressure rod 15 and the pressure block 17 are curved, the corresponding pressure rod 15 and pressure block 17 move in opposite directions, compressing the spring 19. After the first diamond mesh 5 is pressed in, the pressure block 17 and pressure rod 15 will move back under the elastic action of the spring 19, installing the first diamond mesh 5 on the front door 4. At the same time, since the contact side between the first diamond mesh 5 and the fixing plate 16 is flat, the first diamond mesh 5 will not rotate after installation.

[0028] Since the positioning rod 20 passes through the through-hole and is T-shaped, with its horizontal part located above or below the corresponding connecting plate 14, when the first diamond mesh 5 needs to be disassembled, simply turn the knob 12 to make the two moving blocks 21 move in opposite directions, thereby driving the L-shaped block 22, the pressure rod 15 and the pressure block 17 to move through the connecting plate 14, releasing the restriction on the first diamond mesh 5, at which point the first diamond mesh 5 can be taken out.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
