DETAILED DESCRIPTION
[0023] Hereinafter, the present application will be further described in conjunction with specific embodiments, it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.
[0026] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0027] One preferred embodiment of the present application, as shown in Figures 1 to 5 An integrated hydraulic station oil port structure, including an oil port valve block 1. The oil port valve block 1 can be fixedly connected with the external shell of the hydraulic station. The oil port valve block 1 is provided with an oil inlet and an oil outlet, and the oil outlet extends out of the external shell. The oil inlet and the oil outlet are in communication, and the axis of the oil inlet and the axis of the oil outlet are not parallel.
[0028] It should be understood that the integrated hydraulic station needs to process a working oil port on the outer surface to facilitate pipe connection. In the prior art, a double internal thread oil port is usually processed and a hinged joint is installed, and then the entire circuit is connected through in-station welded pipes; however, the double internal thread oil port and welding in the prior art have certain difficulties. For the double internal thread oil port, the machining precision of both sides is very high, and the roughness of the two end faces, the size of the oil port diameter, etc. can all be key factors affecting whether the working oil port will leak; for in-station welding, there are phenomena such as mismatching of the size of the joint and position offset due to deformation of the pipeline during welding, which can also affect whether the working oil port will leak.
[0029] Therefore, in the embodiment, the oil port valve block 1 is arranged to replace the double internal thread oil port in the prior art, so that the machining difficulty of the integrated hydraulic station working oil port is reduced; meanwhile, the design of the oil port valve block 1 in the embodiment also reduces the difficulty of connecting the oil pipe 2. By solving the machining difficulty and welding difficulty in the prior art, the integrated hydraulic station working oil port is no longer leaking.
[0030] In the embodiment, as shown in the figure, Figures 1 to 3 The oil port valve block 1 is arranged with an oil inlet and an oil outlet, and the oil port valve block 1 is in block shape. The oil inlet and the oil outlet are arranged on two adjacent sides of the oil port valve block 1; meanwhile, the oil port valve block 1 is connected with the external shell of the hydraulic station, and the oil inlet extends out of the external shell of the hydraulic station so as to connect the external pipeline with the oil inlet by the staff.
[0031] It can be understood that the oil inlet and the oil outlet are arranged correspondingly, that is, one oil inlet is arranged with one oil outlet, the number of the oil outlets should be the same as that of the oil inlets, and the oil outlet and the corresponding oil inlet are communicated; at this time, the oil inlet is connected with the external pipeline, the oil outlet is connected with the oil pipe 2, and the medium can be transported from the external pipeline to the oil pipe 2 through the communicated oil inlet and oil outlet.
[0032] It can also be understood that, as described above, the axis of the oil inlet and the axis of the oil outlet are not parallel, so there is an included angle between the axis of the oil inlet and the axis of the oil outlet, the included angle is 90°, that is, perpendicular, or the included angle is between 90° and 180°. No matter which one of the above-mentioned included angles between the axis of the oil inlet and the axis of the oil outlet, it can be implemented in the embodiment, but considering that when the axis of the oil inlet and the axis of the oil outlet are inclined to connect the oil pipe 2, it is not very convenient for the actual operation of the staff and not very convenient for processing, so in the embodiment, the axis of the oil inlet and the axis of the oil outlet are perpendicular to each other; meanwhile, during processing, the axis of the oil inlet and the axis of the oil outlet need to be aligned so that the opening of the oil inlet can be aligned with the opening of the oil outlet.
[0033] It can also be understood that the number of oil inlets can be single or multiple; but in actual operation, the working efficiency of a single oil inlet is relatively low and the working process is long, so in the embodiment, the oil inlets and oil outlets are correspondingly provided with multiple, the oil inlets and oil outlets are spaced along the length direction of the oil port valve block 1, and the sizes of the oil inlets and oil outlets are equal; that is, the oil inlets are divided into a first oil inlet 100, a second oil inlet 101, a third oil inlet 102, a fourth oil inlet 103 and a fifth oil inlet 104, and the oil outlets include a first oil outlet 110 corresponding to the first oil inlet 100, a second oil outlet 101 corresponding to the second oil inlet 101, a third oil outlet 112 corresponding to the third oil inlet 102, a fourth oil outlet 113 corresponding to the fourth oil inlet 103, and a fifth oil outlet 114 corresponding to the fifth oil inlet 104; at the same time, the sizes of the first oil inlet 100 and the first oil outlet 110 are equal, the sizes of the second oil inlet 101 and the second oil outlet 111 are equal, the sizes of the third oil inlet 102 and the third oil outlet 112 are equal, the sizes of the fourth oil inlet 103 and the fourth oil outlet 113 are equal, and the sizes of the fifth oil inlet 104 and the fifth oil outlet 114 are equal.
[0034] In the embodiment, the first oil inlet 100, the second oil inlet 101, the third oil inlet 102, the fourth oil inlet 103 and the fifth oil inlet 104 are spaced along the length direction of the oil port valve block 1, but there are many specific arrangement modes. In order to facilitate understanding, two specific examples are described below.
[0035] Example one: as shown in Figure 4 , the sizes of the first oil inlet 100, the second oil inlet 101, the third oil inlet 102, the fourth oil inlet 103 and the fifth oil inlet 104 are not all the same; the first oil inlet 100, the second oil inlet 101, the third oil inlet 102, the fourth oil inlet 103 and the fifth oil inlet 104 can be arranged in order from small to large in size along the length direction of the oil port valve block 1.
[0036] Specifically, the sizes of the first oil inlet 100 and the second oil inlet 101 are the same, the sizes of the third oil inlet 102 and the fourth oil inlet 103 are the same, and the size of the fifth oil inlet 104 is the largest. Therefore, the five oil inlets are arranged in order from small to large in size along the length direction of the oil port valve block 1 as the first oil inlet 100, the second oil inlet 101, the third oil inlet 102, the fourth oil inlet 103 and the fifth oil inlet 104. Such an arrangement can make it easier for workers to identify when using external pipelines for docking.
[0037] Example two: as shown in Figure 5As shown, the first oil inlet 100, the second oil inlet 101, the third oil inlet 102, the fourth oil inlet 103 and the fifth oil inlet 104 are arranged staggeredly.
[0038] Specifically, the first oil inlet 100, the third oil inlet 102 and the fifth oil inlet 104 are arranged linearly and spacedly, and the second oil inlet 101 and the fourth oil inlet 103 are arranged between the first oil inlet 100 and the third oil inlet 102 and between the third oil inlet 102 and the fifth oil inlet 104, respectively; in this way, the distance from the center of the second oil inlet 101 to the center of the first oil inlet 100 and the third oil inlet 102 is increased, that is, the installation radius of the second oil inlet 101 is increased, and thus the installation space is increased; the same is true for the fourth oil inlet 103.
[0039] In the embodiment, the oil port valve block 1 also needs to be detachably fixedly connected with the external shell of the hydraulic machine. Therefore, the two sides of the oil port valve block 1 are provided with connecting portions 12, and a pair of gaskets 3 are arranged on the external shell. The gaskets 3 can be attached to the connecting portions 12, and the gaskets 3 can also be connected with bolts. After the gaskets 3 are attached to the connecting portions 12, the bolts can be connected through the oil port valve block 1 and the gaskets 3.
[0040] It can be understood that the connecting portions 12 are located at the two ends of the side of the oil port valve block 1 on which the plurality of oil inlets are arranged, and connecting holes 120 are arranged on the two connecting portions 12. After the gaskets 3 are attached to the connecting portions 12, the bolts can be threadedly connected through the connecting holes 120 and the gaskets 3, so as to facilitate the later inspection, replacement and the like of the oil port valve block 1.
[0041] In the embodiment, the oil outlet needs to be connected with the oil pipe 2 through a joint, the oil outlet and one end of the joint are connected through threads, and the joint is connected with the oil pipe 2 at the end away from the oil outlet, but the joint and the oil pipe 2 can be connected in various ways, including but not limited to the following two ways.
[0042] The first way: the joint is connected with the oil pipe 2 at the end away from the oil outlet through welding.
[0043] The second way: the joint is connected with the oil pipe 2 at the end away from the oil outlet through threaded connection.
[0044] It should be understood that the above two ways can meet the needs of the present application, and those skilled in the art can choose according to actual needs; in the embodiment, the first way is preferably adopted.
[0045] It should also be understood that the specific structure of the joint for connecting the oil outlet and the oil pipe 2 is known to those skilled in the art, and therefore will not be described here.
[0046] The foregoing describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments, and the above-described embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
