Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, and in particular to a hydraulic station. Background Technology

[0002] Hydraulic power units, as the power core of hydraulic systems, are widely used in engineering machinery, mobile equipment, and emergency rescue scenarios. However, during use, hydraulic power units need to be transported to their location as required. Current hydraulic power units are mostly fixed, integrated structures with rigid connections between the oil tank, pump unit, and valve group, resulting in fixed overall dimensions. In confined spaces such as elevator transport or small vehicle loading, their excessive size often prevents passage. This necessitates disassembling the hydraulic power unit and placing it inside the elevator or small vehicle, then reassembling it after transport to the location of use. This increases transportation and usage time costs and reduces efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a hydraulic station that can solve the above-mentioned technical problems;

[0004] This utility model provides a hydraulic station, comprising:

[0005] The main housing and the installation space at the bottom of the main housing are provided. The installation space has several installation positions and several movable structures are provided at the installation positions. In the transportation state, the movable structures are rotated and placed in the installation space.

[0006] The pump assembly is movably connected to one side of the main housing; in the use state, the pump assembly is located on one side of the main housing; in the transportation state, the pump assembly is flipped over and placed on the top of the main housing; and the pump assembly is connected to the main housing through the inlet pipe and the return pipe respectively.

[0007] The first support frame is rotatably mounted on the pump assembly; in the transport state, the first support frame is rotated and placed on the bottom surface of the pump assembly.

[0008] As a further technical solution, it also includes:

[0009] The secondary compartment is movably connected to the other side of the main compartment; in use, it is located on the other side of the main compartment; in transport, the secondary compartment is flipped over and placed on top of the main compartment.

[0010] As a further technical solution, it also includes:

[0011] The second support frame is rotatably mounted on the sub-box; in the transport state, the second support frame rotates and is placed on the bottom surface of the sub-box.

[0012] As a further technical solution, a first spacer pad is provided on the top of the auxiliary box; in the transportation state, the first spacer pad is placed between the top of the auxiliary box and the top of the main box.

[0013] As a further technical solution, one side of the first spacer extends out of the top of the sub-box, and in the transport state, it is placed between the top of the pump assembly and the main box.

[0014] As a further technical solution, a second spacer is provided on the top of the pump assembly. In the transportation state, the second spacer is placed between the top of the pump assembly and the main housing.

[0015] As a further technical solution, a first connecting plate is provided between the pump assembly and the main housing, and several connecting blocks are provided between the first connecting plates; the several connecting blocks are respectively connected to the first connecting plates on the pump assembly and the main housing through damping shafts.

[0016] As a further technical solution, an installation plate is provided in the installation space, and an installation position is formed between the installation plate and the inner wall of the installation space, with the movable structure set in the installation position.

[0017] As a further technical solution, a rotating hole, a first positioning hole, and a second positioning hole are provided on the mounting position; the moving structure is fixed in the rotating hole by a rotating shaft; in the transport state, the positioning shaft passes through the first positioning hole and places the moving structure in the installation space; in the moving state, the positioning shaft passes through the second positioning hole and places the moving structure outside the installation space.

[0018] As a further technical solution, the pump assembly includes:

[0019] The mounting shell is movably connected to one side of the main housing;

[0020] The pump assembly is fixedly connected inside the mounting housing and is connected to the main tank via an inlet pipe and a return pipe.

[0021] This invention employs a multi-component foldable and retractable design. During transport, the bottom movable structure can rotate and retract into the main housing's installation space, preventing moving parts from occupying extra space. The pump assembly can be flipped to the top of the main housing, no longer extending laterally. The first support frame can rotate to fit the bottom of the pump assembly, further compressing the overall volume. After folding, the overall size of the hydraulic station is significantly reduced, allowing for direct adaptation to elevator transport and small vehicle loading without disassembly. This eliminates the need for disassembly and secondary assembly, significantly reducing time and labor costs during transport, making it particularly suitable for scenarios with extremely high transport efficiency requirements, such as emergency rescue operations.

[0022] Furthermore, in operation, the pump assembly is stably mounted on one side of the main housing via a movable connection structure. The first support frame, once deployed, provides effective support for the pump assembly, ensuring its structural stability during operation and preventing any impact on the hydraulic system's power output due to loose connections. The bottom movable structure, once deployed, facilitates short-distance movement and adjustment of the hydraulic station at the site. Simultaneously, the pump assembly maintains stable communication with the main housing via inlet and return pipes, ensuring smooth hydraulic oil delivery and not affecting the hydraulic station's core power function. This achieves a balance between convenient transportation and stable operation, avoiding any sacrifice of equipment performance due to structural optimization.

[0023] Compared to the fixed structure of existing technologies, the modular and foldable design of this utility model offers greater adaptability to various scenarios: in engineering machinery operations, it can flexibly reach work points through narrow passages; when used with mobile equipment, it can adapt to the space constraints of different transport vehicles; in temporary emergency rescue scenarios, it can quickly complete transportation and deployment, saving time for rescue work. Furthermore, this design eliminates the need for complex disassembly and assembly tools, allowing operators to quickly switch between states, lowering the barrier to entry for equipment use, further enhancing the practical value of the hydraulic station, and providing structural support for the application expansion of hydraulic systems.

Detailed Implementation

[0033] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] like Figure 1-6 As shown, the hydraulic station proposed in this utility model includes:

[0037] The main housing 100 and the installation space 101 recessed at the bottom of the main housing 100 are provided. The installation space 101 contains several installation positions 102, and several movable structures 200 are installed on these installation positions 102. During transport (entering an elevator or small vehicle), the movable structures 200 rotate and are positioned within the installation space 101. In actual use, adjustments can be made as needed. For example, if the movable structures 200 are needed to support the entire structure and change its position, they can be placed outside the installation space 101, thereby changing the overall position. If a reduction in overall height is required, the movable structures 200 can be folded and placed inside the installation space 101 to lower the overall height. In this invention, the installation positions 102 are located at the four corners of the installation space 101. Therefore, four movable structures 200 are provided, each located on one of the four corner installation positions 102.

[0038] The pump assembly 300 is movably connected to one side of the main housing 100; in use, the pump assembly 300 is located on one side of the main housing 100; in transport, the pump assembly 300 is flipped over and placed on top of the main housing 100; and the pump assembly 300 is connected to the main housing 100 through an inlet pipe 303 and a return pipe 304 respectively; in this utility model, the pump assembly 300 includes a mounting housing 302 movably connected to one side of the main housing 100; the pump assembly (not shown in the figure) is fixedly connected in the mounting housing 302 and is connected to the main housing 100 through the inlet pipe 303 and the return pipe 304; specifically, the pump assembly includes a motor as in the prior art. The system includes an oil pump and pipelines; the hydraulic pump is connected to the inlet pipe 303 via a pipeline, which in turn connects to the inlet chamber inside the main housing 100. Driven by a motor, the oil pump draws oil from the inlet chamber and transmits it through the pipeline to the terminal (hydraulic equipment) for use. After the terminal has finished using the equipment, the oil is transmitted through the pipeline to the return pipe 304, and then back to the return chamber inside the main housing 100. The return chamber and the inlet chamber are separated by a partition, and a through hole is provided on the partition to connect the return chamber and the inlet chamber, allowing the oil in the return chamber to be transported back to the inlet chamber for subsequent use.

[0039] The pump assembly 300 is equipped with a first connecting pipe and a second connecting pipe, respectively, in the inlet chamber and the return chamber. The inlet pipe 303 is connected to the first connecting pipe via a quick connector, and the return pipe 304 is connected to the second connecting pipe via a quick connector. This allows for quick removal of the inlet pipe 303 and the return pipe 304 when the pump assembly 300 is folded, improving folding efficiency. Additionally, the pump assembly 300 is equipped with a wire hole (not shown in the figure), which allows connection to the motor inside the pump assembly 300 via a wire, enabling external power to supply power to the motor. The quick connector uses an O-ring seal with a sealing pressure ≥10MPa. An elastic buckle is provided on the outside of the quick connector, with an insertion depth ≥8mm and an insertion / extraction force of 220-250N, preventing the quick connector from detaching during transportation or use and causing oil leakage.

[0040] The first support frame 400 is rotatably mounted on the pump assembly 300. In the transport state, the first support frame 400 rotates and rests on the bottom surface of the pump assembly 300. When the entire assembly is transported to its intended use, the first support frame 400 is adjusted to support the pump assembly 300, ensuring its stability during use. During transport, the first support frame 400 is folded and placed on the pump assembly 300, preventing it from occupying space. The first support frame 400 includes support legs 401 and support arms 402, with the support legs 401 resting on the bottom surface of the pump assembly 300. The first protrusion of the part is connected by a pin; and the support leg 401 is provided with a connecting hole. One end of the support arm 402 is connected to the connecting hole by a pin, and the other end is connected to the second protrusion provided on the pump assembly 300 by a pin. In the transportation state, after removing the pin between the other end of the support arm 402 and the second protrusion, the support of the support arm 402 on the support leg 401 is released, and the support leg 401 and the support arm 402 are folded. In use, the support arm 402 is aligned with the second protrusion and the pin is installed. After installation, the pump assembly 300 is supported by the cooperation of the support arm 402 and the support leg 401.

[0041] This utility model's technical solution employs a multi-component foldable storage design. In transport mode, the bottom movable structure 200 can rotate and retract into the installation space 101 of the main housing 100, preventing moving parts from occupying extra space. The pump assembly 300 can flip to the top of the main housing 100, no longer extending laterally. The first support frame 400 can rotate to fit against the bottom surface of the pump assembly 300, further compressing the overall volume. After folding, the overall size of the hydraulic station is significantly reduced, allowing direct adaptation to elevator transport and small vehicle loading without disassembly, eliminating disassembly and secondary assembly steps, and significantly reducing time and labor costs during transportation. It is particularly suitable for scenarios with extremely high transportation efficiency requirements, such as emergency rescue operations.

[0042] In addition, during operation, the pump assembly 300 is stably mounted on one side of the main housing 100 via a movable connection structure. The first support frame 400, once deployed, provides effective support for the pump assembly 300, ensuring its structural stability during operation and preventing any impact on the hydraulic system's power output due to loose connections. The bottom movable structure 200, once deployed, facilitates short-distance movement and adjustment of the hydraulic station at the operating site. Simultaneously, the pump assembly 300 maintains stable communication with the main housing 100 via the inlet pipe 303 and return pipe 304, ensuring smooth hydraulic oil delivery and not affecting the core power function of the hydraulic station. This achieves a balance between convenient transportation and stable operation, avoiding any sacrifice of equipment performance due to structural optimization.

[0043] Compared to the fixed structure of existing technologies, the modular and foldable design of this utility model offers greater adaptability to various scenarios: in engineering machinery operations, it can flexibly reach work points through narrow passages; when used with mobile equipment, it can adapt to the space constraints of different transport vehicles; in temporary emergency rescue scenarios, it can quickly complete transportation and deployment, saving time for rescue work. Furthermore, this design eliminates the need for complex disassembly and assembly tools, allowing operators to quickly switch between states, lowering the barrier to entry for equipment use, further enhancing the practical value of the hydraulic station, and providing structural support for the application expansion of hydraulic systems.

[0044] like Figure 1 As shown, to ensure sufficient oil for actual use, this invention includes a secondary housing 500, which is movably connected to the other side of the main housing 100. In use, it is positioned on the other side of the main housing 100. In transport, the secondary housing 500 is flipped over and placed on top of the main housing 100. During use, the secondary housing 500 and the main housing 100 are connected via an oil pipe (not shown in the figure), and a quick-connect coupling is used between the oil pipe and the secondary housing 500 and the main housing 100. This facilitates quick disassembly of the oil pipe when the secondary housing 500 is folded. Alternatively, an oil pump (not shown in the figure) can be installed on the oil pipe to increase the oil flow rate and ensure sufficient oil supply in the secondary housing 500. The oil in the tank 0 can enter the main tank 100 more smoothly. It should be noted that a first cover and a second cover are respectively provided on the top of the main tank 100 and the auxiliary tank 500. The first cover and the second cover are connected to the main tank 100 and the auxiliary tank 500 by bolts, respectively. At the same time, oil-resistant sealing rings are provided between the first cover and the main tank 100 and between the second cover and the auxiliary tank 500, thereby ensuring the sealing of the oil in the main tank 100 and the auxiliary tank 500. In addition, oil inlet holes are provided on the first cover and the second cover, through which oil can be injected into the main tank 100 or the auxiliary tank 500. At the same time, a threaded sealing cap is provided on the oil inlet hole to ensure that the oil does not leak at the oil inlet hole.

[0045] In addition, no oil is stored inside the secondary housing 500 during transportation to prevent leakage between the secondary housing 500 and the second cover if it is tipped over. Any oil requiring storage in the secondary housing 500 must be stored in a separate container, which will be transported along with the secondary housing 500. Once the secondary housing 500 is in place, its position is adjusted, and the oil is poured into it through the oil inlet on the second cover. The oil inlet on the second cover is a funnel-shaped inlet. An exhaust valve is provided. When oil is poured into the auxiliary tank, the gas inside the auxiliary tank 500 is discharged through the exhaust valve to prevent cavitation in the auxiliary tank 500 when oil is poured in. After the oil is poured in, a sealing cap is placed on the oil inlet and the exhaust valve is closed. In addition, an oil drain valve (not shown in the figure) is provided on both the main tank 100 and the auxiliary tank 500, which can drain the oil in the main tank 100 and the auxiliary tank 500 as needed. The specific method depends on the actual situation, and this utility model does not further limit it.

[0046] Furthermore, considering that the secondary container 500 only increases the capacity of the main container 100 and minimizes the overall weight during transportation, the size of the secondary container 500 is smaller than that of the main container 100. This means that the bottom of the secondary container 500 cannot contact the usage position during use. Therefore, in this invention, a second support frame 600 is rotatably mounted on the secondary container 500. During transportation, the second support frame 600 rotates and rests on the bottom surface of the secondary container 500. During use, the second support frame 600 supports the secondary container 500, ensuring its stability during operation. In this utility model, the second support frame 600 has the same structure as the first support frame 400. The only difference is that the second support frame 600 needs to be adjusted in size to connect with the auxiliary housing 500 in order to be used with the auxiliary housing 500. However, the connection relationship and support principle between the second support frame 600 and the auxiliary housing 500 are the same as the connection relationship and support principle between the first support frame 400 and the pump assembly 300. To save space, this utility model will not be described further.

[0047] like Figure 1 and Figure 3 As shown, a first spacer pad 501 is provided on the top of the sub-box 500; in the transportation state, the first spacer pad 501 is placed between the top of the sub-box 500 and the top of the main box 100; specifically, the first spacer pad 501 is located on the side of the top of the sub-box 500 away from the main box 100, so that when the sub-box 500 is flipped over and placed on top of the main box 100, the first spacer pad 501 can separate the sub-box 500 from the main box 100, avoiding direct contact between the sub-box 500 and the main box 100, thus preventing wear on the sub-box 500 or the main box 100; wherein, the first spacer pad 501 is preferably a rubber pad;

[0048] Of course, one side of the first spacer 501 extends out of the top of the auxiliary housing 500, and in the transport state, it is placed between the top of the pump assembly 300 and the top of the main housing 100; in this way, the first spacer 501 can ensure that the top of the auxiliary housing 500 does not contact the top of the main housing 100, and can also isolate the top of the pump assembly 300 from the top of the main housing 100, thereby avoiding wear on the top of the pump assembly 300 or the main housing 100. Figure 3 and Figure 4 As shown, when the pump assembly 300 and the auxiliary housing 500 are flipped over and placed on top of the main housing 100, the pump assembly 300 and the auxiliary housing 500 are placed side by side, thereby ensuring that the pump assembly 300 can be pressed on the first spacer pad 501.

[0049] In another embodiment of the present invention, a second spacer 301 is provided on the top of the pump assembly 300. In the transportation state, the second spacer 301 is placed between the top of the pump assembly 300 and the top of the main housing 100. In the transportation state, the second spacer 301 prevents the top of the pump assembly 300 and the top of the main housing 100 from contacting each other, thereby preventing wear on the top of the pump assembly 300 or the top of the main housing 100.

[0050] like Figure 2 As shown, a first connecting plate 701 is provided between the pump assembly 300 and the main housing 100, and a plurality of connecting blocks 702 are provided between the first connecting plates 701; the plurality of connecting blocks 702 are respectively connected to the first connecting plates 701 on the pump assembly 300 and the main housing 100 via damping shafts 703; in use, the connecting blocks 702 are placed on the first connecting plates 701 and the second connecting plates on the pump assembly 300 and the main housing 100 via the damping shafts 703, and the first connecting plates 701 and the second connecting plates are restricted by the damping shafts 703, thereby causing the pump assembly 300 to be positioned on the first connecting plate 701 and the second connecting plate 100 via the damping shafts 703. Supported by the support frame 400, the pump assembly 300 is placed on one side of the main housing 100. In the transport state, the pump assembly 300 is operated to rotate 180° around the damping shaft 703 until the top of the pump assembly 300 is placed on top of the main housing 100, thus completing the pump assembly 300 flipping operation. In addition, since the pump assembly 300 contains components such as a motor and an oil pump, when the pump assembly 300 is placed on top of the main housing 100, it can be stably placed on top of the main housing 100 under the weight of the motor and oil pump components.

[0051] It should be noted that the auxiliary housing 500 and the main housing 100 are also connected by the first connecting plate 701, the connecting block 702 and the damping shaft 703. To save space, the connection method and principle between the auxiliary housing 500 and the main housing 100 will not be further explained. When the auxiliary housing 500 is placed on top of the main housing 100, its weight makes it stable on top of the main housing 100. The damping force of the damping shaft 703 is 50-100 N·m, which ensures that the flipping process is smooth and there is no loosening after folding.

[0052] like Figure 5 and Figure 6 As shown, an installation plate 103 is provided in the installation space 101, and an installation position 102 is formed between the installation plate 103 and the inner wall of the installation space 101. The movable structure 200 is provided in the installation position 102. The movable structure 200 can rotate in the installation position 102 as needed, thereby supporting and moving the whole, or folding into the installation space 101 to reduce the overall space occupied.

[0053] The mounting position 102 is provided with a rotating hole 104, a first positioning hole 105, and a second positioning hole 106. The moving structure 200 is fixed in the rotating hole 104 by a rotating shaft. In the transport state, the positioning shaft passes through the first positioning hole 105, and the moving structure 200 is placed in the mounting space 101. In the moving state, the positioning shaft passes through the second positioning hole 106, and the moving structure 200 is placed outside the mounting space 101. It should be noted that the moving state is only used for short-distance position adjustment of the hydraulic station at the site of use. After the adjustment is completed (i.e., entering the use state), the positioning shaft needs to be pulled out from the second positioning hole 106, the moving structure 200 is rotated into the mounting space 101, and then the positioning shaft is fixed by passing through the first positioning hole 105, so that the hydraulic station directly contacts the ground through the bottom of the main housing 100, ensuring stability during use and avoiding displacement caused by the rollers being stressed.

[0054] By changing the installation of the movable structure 200 with the first positioning hole 105 or the second positioning hole 106, the angle of the movable structure 200 can be changed, thereby enabling the entire assembly to be supported or folded into the installation space 101 by the movable structure 200. The movable structure 200 includes a mounting frame 201 and rollers 202. The rollers 202 are rotatably mounted on the mounting frame 201, which has a first hole and a second hole. The first hole and the rotating hole 104 are connected by a rotating shaft. During adjustment, the first hole rotates around the rotating shaft. The position of the rollers 202 is adjusted by changing the connection between the positioning shaft and the first positioning hole 105 or the second positioning hole 106 and the second hole. In this invention, the positioning shaft is preferably a pin.

[0055] It should be noted that one end of the pin shaft in this utility model is provided with a pin hole with a diameter of 6mm. When the pin shaft is used to fix the support leg, connecting arm or mounting bracket, after the pin shaft is inserted, a cotter pin with a diameter of 5mm is inserted into the pin hole. The bending angle of both ends of the cotter pin is ≥90° to prevent the pin shaft from falling off during use or transportation.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
