Abstract
Description
Technical Field
[0001] This application relates to the field of hydraulic pump station technology, specifically to a combined hydraulic pump station. Background Technology
[0002] In today's industrial and engineering fields, hydraulic pump stations, as key equipment providing hydraulic power, are widely used in various working conditions. Traditional mobile hydraulic pump stations generally adopt an integrated design, typically consisting of an engine, hydraulic oil tank, cooling system, and frame, and are equipped with tires for easy manual movement. This conventional structure can meet basic usage requirements in general operating scenarios.
[0003] However, with the increasing diversity and complexity of operating environments, especially in special conditions such as plateaus, hillsides, and low-lying, uneven areas, integrated hydraulic pump stations have revealed many significant drawbacks. On the one hand, their large size makes turning and passage in narrow, rugged terrain extremely difficult, and they are easily obstructed by surrounding obstacles. On the other hand, their heavy weight not only increases the difficulty of transportation, but also makes it almost impossible for a single person to move them, often requiring the use of additional carrying tools or the cooperation of multiple people. This undoubtedly greatly limits work efficiency, increases manpower and material costs, and in some emergency rescue or situations requiring extremely high mobility, they cannot be quickly deployed, seriously affecting the progress of the project.
[0004] Therefore, there is an urgent need to develop a new type of hydraulic pump station structure to overcome the application limitations of existing integrated hydraulic pump stations in special and complex environments and to meet diverse operational needs. Utility Model Content
[0005] This utility model addresses the aforementioned problems in the existing technology by providing a combined hydraulic pump station.
[0006] The objective of this utility model is mainly achieved through the following solution:
[0007] A combined hydraulic pump station includes a power module and a cooling module. The power module includes a power frame and a power engine installed within the power frame. One end of the power engine is connected to a hydraulic pump assembly, which has a hydraulic pump output interface and a hydraulic pump input interface. The cooling module includes a cooling frame and a hydraulic oil tank, a fan engine, a cooling component, and a control valve assembly installed within the cooling frame. The hydraulic oil tank is connected to a hydraulic pump inlet. The control valve assembly has an oil circuit control valve input interface, an oil circuit control valve output interface, and a quick return interface. The hydraulic pump inlet is connected to the hydraulic pump input interface via a first pipeline. The hydraulic pump output interface is connected to the oil circuit control valve input interface via a second pipeline. The oil circuit control valve output interface is connected to the oil inlet of a hydraulic tool via a third pipeline. The hydraulic tool's outlet is connected to the quick return interface via a fourth pipeline. The control valve assembly is also connected to the hydraulic oil tank via a fifth pipeline.
[0008] Preferably, the upper sides of the power frame and the heat dissipation frame are symmetrically provided with handles, and one side of the power frame and the heat dissipation frame is provided with a backrest, and a shoulder strap is installed on the backrest.
[0009] Preferably, the heat dissipation component is installed at the air outlet of the fan engine, and the fifth pipeline is connected to the hydraulic oil tank after passing through the heat dissipation component.
[0010] In summary, compared with the prior art, the present invention has the following beneficial technical effects:
[0011] (1) By splitting the hydraulic pump station into a power module and a heat dissipation module, the weight of a single module is greatly reduced. In complex terrains such as plateaus and hillsides, operators can choose to carry the equipment quickly by one person or two people by hand, depending on the actual situation. This breaks away from the dilemma of traditional integrated hydraulic pump stations being difficult to move due to their large size and heavy weight, and greatly improves the speed of on-site deployment of the equipment. It is especially suitable for scenarios with high mobility requirements such as disaster relief and temporary field operations.
[0012] (2) In this utility model, the power module and the heat dissipation module can be put into use by simply connecting them through hydraulic oil pipes. The connection process is simple and easy to understand, without the need for professional and complicated assembly procedures, which reduces the technical threshold for operators, reduces the installation and debugging time of the equipment, and effectively improves the overall work efficiency.
[0013] (3) The combination of the fan motor and the heat dissipation component of the heat dissipation module in this utility model can dissipate the high temperature hydraulic oil in time, ensure the stability of the hydraulic oil performance, and avoid the wear of key components such as hydraulic pump and control valve group caused by excessive oil temperature, or the occurrence of failure. It provides reliable heat dissipation guarantee for long-term and high-intensity operation, and extends the maintenance cycle and service life of the equipment. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.
[0021] Example 1:
[0022] like Figure 1 , 2 As shown in Figure 3, this utility model discloses a technical solution: a combined hydraulic pump station, which consists of a power module and a heat dissipation module.
[0023] Specifically, the power module includes a power frame D1 and a power engine D2 that is detachably and fixedly installed in the power frame D1 by bolts. One end of the power engine D2 is connected to a hydraulic pump assembly D3, and the hydraulic pump assembly D3 is provided with a hydraulic pump output interface D4 and a hydraulic pump input interface D5.
[0024] Specifically, the heat dissipation module includes a heat dissipation frame S1 and a hydraulic oil tank S2, a fan engine S3, a heat dissipation component S4, and a control valve group S5 that are detachably installed in the heat dissipation frame S1. The hydraulic oil tank S2 is connected to a hydraulic pump inlet S6. The control valve group S5 is equipped with an oil circuit control valve input interface S7, an oil circuit control valve output interface S8, and a quick return oil interface S9.
[0025] Specifically, the hydraulic pump inlet S5 is connected to the hydraulic pump input interface D5 via the first pipeline G1, the hydraulic pump output interface D4 is connected to the oil circuit control valve input interface S7 via the second pipeline G2, the oil circuit control valve output interface S8 is connected to the hydraulic tool inlet via the third pipeline G3, the hydraulic tool outlet is connected to the return oil quick interface S9 via the fourth pipeline G4, and the control valve group S5 is also connected to the hydraulic oil tank S2 via the fifth pipeline G5; the control valve group S5 can control the on / off connection between the second pipeline G2 and the third pipeline G3, and between the fourth pipeline G4 and the fifth pipeline G5.
[0026] When using it, first follow Figure 3 After the pipelines are connected, when the power engine D2 starts, the main shaft drives the hydraulic pump assembly D3 to operate. The impeller in the hydraulic pump assembly D3 rotates at high speed, drawing hydraulic oil from the hydraulic oil tank S2 into the pump through the first pipeline G1, and then into the control valve group S5 through the second pipeline G2. When the control valve group S5 is opened, the hydraulic oil flows into the hydraulic tool through the third pipeline G3, driving the hydraulic tool to work. After driving the hydraulic tool, the hydraulic oil flows into the return oil line of the control valve group S5 through the fourth pipeline G4, and then into the cooling component through the fifth pipeline G5. The hydraulic oil cooled by the cooling component flows back into the hydraulic oil tank S2, forming a cycle. The power engine D2 and the fan engine S3 are powered by a battery or a small generator.
[0027] Example 2:
[0028] like Figure 1 As shown, this utility model discloses another technical solution, a combined hydraulic pump station. The difference from embodiment 1 is that the upper sides of the power frame D1 and the heat dissipation frame S1 are symmetrically provided with handles D6, and one side of the power frame D1 and the heat dissipation frame S1 is equipped with a backrest D7. A shoulder strap D8 is installed at the backrest D7, which greatly facilitates the operator's handling of individual modules. Whether it is carried by one person or lifted by two people, it can be easily achieved, effectively improving the mobility of the equipment in complex terrain and reducing the dependence on external handling tools.
[0029] Example 3:
[0030] like Figure 1As shown, this utility model discloses another technical solution, a combined hydraulic pump station. The difference from embodiment 1 is that the above-mentioned heat dissipation component S4 is installed at the air outlet of the fan engine S3. The fifth pipeline G5 is connected to the hydraulic oil tank S2 after passing through the heat dissipation component S4. The specific heat dissipation component includes a shell and a heat dissipation coil inside the shell. The outer wall of the heat dissipation coil is welded with multiple sets of heat dissipation fins. The fifth pipeline G5 and the hydraulic oil tank S2 are connected to the two ends of the heat dissipation coil. When the hydraulic oil flows through the heat dissipation coil, the heat is dissipated into the air through the heat dissipation fins, completing the heat exchange between the hydraulic oil, air and heat dissipation fins.
[0031] This utility model provides a combined hydraulic pump station, which significantly reduces the weight of individual modules by splitting the hydraulic pump station into a power module and a heat dissipation module. In complex terrains such as plateaus and hillsides, operators can choose to carry the equipment quickly by one person or two people by hand, depending on the actual situation. This overcomes the difficulty of moving traditional integrated hydraulic pump stations due to their large size and heavy weight, greatly improving the speed of on-site deployment. It is especially suitable for scenarios with extremely high mobility requirements, such as disaster relief and temporary field operations. The power module and the heat dissipation module can be put into use simply by connecting them through hydraulic oil pipes. The connection process is simple and easy to understand, without the need for professional and complicated assembly procedures, which lowers the technical threshold for operators, reduces the installation and commissioning time of the equipment, and effectively improves the overall work efficiency. The fan motor and heat dissipation components of the heat dissipation module can dissipate the high temperature hydraulic oil in time, ensuring the stability of the hydraulic oil performance and avoiding the accelerated wear or failure of key components such as hydraulic pumps and control valve groups due to excessive oil temperature. This provides reliable heat dissipation guarantee for long-term, high-intensity operations and extends the maintenance cycle and service life of the equipment.
[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
