Description

Technical Field

[0001] This invention relates to the field of hydraulic station technology, and particularly to a hydraulic station that facilitates pipeline connection. Background Technology

[0002] This is a crucial aspect of the process. In the traditional piping connection structure of a hydraulic power unit, it is usually necessary to precisely align the first flange of the hydraulic power unit body with the second flange of the hydraulic oil pipeline, and then fix them by bolts through the threaded holes.

[0003] However, in actual operation, due to the weight of the hydraulic oil pipeline itself and the lack of an effective pre-fixed support structure, the second flange is prone to displacement or tilting due to the weight of the pipeline or external disturbance when connecting flanges. This makes it difficult to quickly align the threaded holes of the first and second flanges, requiring multiple people to work together to repeatedly adjust the posture. This not only increases the installation time, but may also damage the threads when the bolts are forcibly tightened due to the misalignment, affecting the connection strength.

[0004] Therefore, a hydraulic station that is easy to connect to pipelines needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hydraulic station that facilitates pipeline connection. This invention integrates pre-fixation and precise positioning functions, and is easy to operate, thereby optimizing the installation process and improving connection quality and efficiency.

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

[0007] A hydraulic station that facilitates pipeline connection includes a hydraulic station body. Hydraulic oil pipelines are provided on both the left and right sides of the hydraulic station body. First flanges are provided on both the left and right sides of the hydraulic station body. Second flanges are fixedly connected to adjacent sides of two hydraulic oil pipelines. Pre-fixing components are provided on both the left and right sides of the hydraulic oil pipelines. Each pre-fixing component includes multiple L-shaped blocks disposed outside the first flanges. A slide rail is mounted on each L-shaped block, and a slider is slidably connected to each slide rail. A wedge-shaped block is fixedly connected to the side of each slider closest to the hydraulic station body. Each wedge-shaped block is elastically connected to its corresponding L-shaped block via a first spring.

[0008] Preferably, each of the two first flanges is provided with multiple threaded holes, and each of the two second flanges is provided with fixing bolts that mate with the multiple threaded holes. A sealing ring is provided between the two first flanges and the corresponding second flanges.

[0009] Preferably, each wedge block is provided with a positioning component, the positioning component including a telescopic plate fixedly connected to the wedge block, a positioning block fixedly connected to the side of the telescopic plate near the second flange, the positioning block and the wedge block being elastically connected by a second spring, and the second flange being provided with a plurality of positioning holes.

[0010] Preferably, each L-shaped block is provided with a limiting component, the limiting component including a pressing plate, and two limiting rods are fixedly connected to the side of the pressing plate near the L-shaped block, the two limiting rods passing through the L-shaped block.

[0011] Preferably, the side of each wedge block away from the hydraulic station body is an inclined surface, and the side of each positioning block close to the hydraulic station body is an arc surface.

[0012] Preferably, the plurality of pre-fixing components are arranged in a ring array along the outer wall of the first flange, and the plurality of positioning holes are arranged in a ring array along the outer wall of the hydraulic oil pipeline.

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

[0014] 1. Compared with the existing technology, the pre-fixing components distributed in a ring array achieve symmetrical clamping of the second flange. The elastic pre-tightening structure of the wedge block and the first spring can provide stable pre-fixing support for the pipe flange and avoid displacement or tilting caused by the pipe's own weight or external force.

[0015] 2. Compared with the existing technology, the positioning component and the pre-fixing component form an efficient cooperation. After the second flange is stably clamped by the pre-fixing component, the positioning block can be driven to accurately align with the positioning groove by rotating the hydraulic oil pipe. With the elastic thrust of the second spring, the positioning block is naturally inserted into the positioning groove, thereby driving the threaded holes of the first flange and the second flange to quickly align. The operation logic is clear and no complicated debugging is required, which greatly reduces the difficulty of manual alignment.

[0016] 3. Compared with existing technologies, during disassembly, the wedge block can be pushed to move away from the hydraulic oil pipe, and the limiting rod effectively blocks the wedge block to avoid its reset interference, which facilitates the quick separation of the first flange and the second flange.

[0021] 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.

[0022] Reference Figures 1-3 A hydraulic station for easy pipeline connection includes a hydraulic station body 1. Hydraulic oil pipes 2 are provided on both the left and right sides of the hydraulic station body 1. First flanges 3 are provided on both the left and right sides of the hydraulic station body 1. The axis of the first flanges 3 is collinear with the axis of the oil outlet of the hydraulic station body 1. Second flanges 4 are fixedly connected to adjacent sides of the two hydraulic oil pipes 2. The axis of the second flanges 4 is collinear with the axis of the hydraulic oil pipes 2. The outer diameter and thickness of the first flanges 3 and second flanges 4 are the same. Pre-fixing components are provided on both the left and right sides of the hydraulic oil pipes 2. The pre-fixing components include multiple L-shaped blocks 5 located outside the first flanges 3. There are four L-shaped blocks 5 evenly distributed along the circumference of the first flanges 3. Each L-shaped block 5 is equipped with a slide rail 6. Each slide rail 6 is slidably connected to a slider 7. Each slider 7 is fixedly connected to a wedge-shaped block 8 on the side closest to the hydraulic station body 1. Each wedge-shaped block 8 is elastically connected to the corresponding L-shaped block 5 via a first spring 9.

[0023] Each of the two first flanges 3 has multiple threaded holes, with a total of four threaded holes. Each of the two second flanges 4 has fixing bolts 15 that mate with the multiple threaded holes. The fixing bolts 15 are threadedly connected to the threaded holes. A sealing ring is provided between the two first flanges 3 and the corresponding second flanges 4. The sealing ring is made of nitrile rubber and is embedded in an annular sealing groove on the side of the first flange 3 near the second flange 4. The depth of the sealing groove is half the thickness of the sealing ring.

[0024] Each wedge block 8 is equipped with a positioning component, which includes a telescopic plate 11 fixedly connected to the wedge block 8. A positioning block 13 is fixedly connected to the side of the telescopic plate 11 near the second flange 4. The positioning block 13 and the wedge block 8 are elastically connected by a second spring 12. The second flange 4 is provided with multiple positioning holes 16. The side of each wedge block 8 away from the hydraulic station body 1 is an inclined surface, and the side of each positioning block 13 near the hydraulic station body 1 is an arc surface, so that the positioning block 13 can move synchronously with the movement of the wedge block 8. Multiple pre-fixing components are distributed in a ring array along the outer wall of the first flange 3, and the included angle between two adjacent pre-fixing components is equal. Multiple positioning holes 16 are distributed in a ring array along the outer wall of the hydraulic oil pipeline 2.

[0025] Each L-shaped block 5 is equipped with a limiting component, which includes a pressing plate 10. Two limiting rods 14 are fixedly connected to the side of the pressing plate 10 near the L-shaped block 5, and the two limiting rods 14 pass through the L-shaped block 5.

[0026] The functional principle of this utility model can be explained through the following operation: During the installation stage, firstly, the second flange 4 of the hydraulic oil pipeline 2 is aligned with the first flange 3 of the hydraulic station body 1. Then, the second flange 4 is pushed towards the first flange 3, and the outer peripheral wall of the second flange 4 contacts the inclined surface of the wedge block 8, forcing the wedge block 8 to move along the slide rail 6 away from the axis of the first flange 3. At this time, the first spring 9 is compressed. After the first flange 3 contacts the second flange 4, the pushing force is removed. Under the elastic action of the first spring 9, the wedge block 8 moves back along the slide rail 6 and forms a symmetrical clamp on the second flange 4, achieving stable pre-fixation and preventing the pipeline from shifting due to its own weight. At the same time, the positioning block 13 of the positioning component moves with the wedge block 8 and contacts the surface of the second flange 4, and the second spring 12 is in a compressed and ready-to-release state. Then, the hydraulic oil pipe 2 is rotated, which drives the second flange 4 to rotate slowly. When the positioning block 13 is aligned with the positioning hole 16 on the second flange 4, the second spring 12 pushes the positioning block 13 so that it automatically inserts into the positioning hole 16. At this time, the threaded holes of the first flange 3 and the second flange 4 are synchronously and accurately aligned.

[0027] During the disassembly phase, the wedge block 8 is first pushed upwards, moving along the slide rail 6 away from the hydraulic oil pipe 2, compressing the first spring 9. Once the wedge block 8 has moved to the appropriate position, the pressing plate 10 of the limiting assembly is pushed, causing the limiting rod 14 to pass through the L-shaped block 5 and move to the side of the slider 7 closest to the hydraulic oil pipe 2, thus blocking the slider 7 and preventing the wedge block 8 from resetting under the action of the first spring 9. After all wedge blocks 8 have moved and been fixed by the limiting rod 14, the fixing bolts 15 can then be removed.

[0028] It is worth mentioning that since the side of the positioning block 13 closest to the hydraulic station body 1 is an arc surface, when the second flange 4 is pre-fixed, the second flange 4 will block the positioning block 13 to move and compress the second spring 12. When the hydraulic oil pipeline 2 is removed, the wedge block 8 moves upward and drives the positioning block 13 to move upward. The hole wall of the positioning hole 16 will contact the arc surface, causing the positioning block 13 to move and compress the second spring 12.

[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.
