Description

Technical Field

[0001] This utility model belongs to the field of hydraulic pump station technology, specifically relating to a hydraulic pump station with a hydraulic pipeline circulation flushing structure. Background Technology

[0002] In the field of hydraulic systems, hydraulic pump stations serve as the core power source, and their stability and reliability directly affect the operating efficiency and safety of the entire hydraulic system. With the continuous advancement of industrial technology, the design of hydraulic pump stations has become increasingly complex, and the requirements for maintenance have also increased, especially the cleanliness requirements of their internal hydraulic pipelines. Therefore, many hydraulic pump stations now have a hydraulic pipeline circulation flushing function, which can periodically circulate and flush the hydraulic pipelines to remove impurities inside the pipes. For example, the existing patent with publication number CN201940277U discloses "a vertical mill hydraulic pump station with a hydraulic pipeline circulation flushing device, which is composed of a vertical mill hydraulic pump station oil source, a vertical mill hydraulic pump station control device, an oil tank, a pump motor unit for circulation flushing, a strong magnetic pipeline filter, a return oil filter, an overflow valve, an integrated oil circuit block, a flushing pipe joint, a two-position three-way shut-off valve, a pressure gauge, hydraulic oil pipes, etc." It can be seen that the application describes a common hydraulic pump station with a hydraulic pipeline circulation flushing structure.

[0003] However, in actual use, the existing hydraulic pump station with hydraulic pipeline circulation flushing structure lacks a structure designed to support and protect the flushing pipe. As a result, the flushing pipe is prone to collapse, bending, or entanglement and deformation under the action of high-pressure hydraulic oil during the flushing process, leading to a decrease in flushing efficiency and even blockage of the pipeline. This seriously affects the normal use of the circulation flushing function and reduces the operational stability of the entire hydraulic pump station. Therefore, this utility model proposes a hydraulic pump station with hydraulic pipeline circulation flushing structure. Utility Model Content

The system includes flushing pipe 1 51 and flushing pipe 2 52, and the side of the oil pipe seat 7 is provided with hydraulic pipeline 1 71 and hydraulic pipeline 2 72 respectively connected to flushing pipe 1 51 and flushing pipe 2 52. After the subsequent circulating flushing pump 4 is started, hydraulic oil can be sent into hydraulic pipeline 1 71 and hydraulic pipeline 2 72 through integrated oil circuit block 5, flushing pipe 1 51 and flushing pipe 2 52 for flushing. The flushed hydraulic oil is then sent back to hydraulic pump station control device 3 and finally flows back to integrated oil circuit block 5 and circulating flushing pump 4 through three-way valve 8. The above structure is a technology that has been disclosed in existing patents. For the specific structural principle, please refer to the existing patent with publication number CN201940277U. It will not be elaborated here.

[0023] And a support and limiting structure 6 is provided on the back of the oil tank 1 and at the bottom of flushing pipe 1 51 and flushing pipe 2 52. The support and limiting structure 6 includes a side seat 61 welded and fixed to the back of the oil tank 1, a support seat 63 installed on the surface of the side seat 61, and a support block 64 welded and fixed to the top of the rear end of the support seat 63. The top of the support block 64 has two U-shaped slots 641. Flushing pipe 1 51 and flushing pipe 2 52 are respectively embedded in the two U-shaped slots 641, which can effectively support flushing pipe 1 51 and flushing pipe 2 52, preventing them from collapsing, bending or blocking due to external force during the flushing process, and ensuring smooth flow of flushing oil.

[0024] In this embodiment, preferably, a T-shaped groove 65 is formed through the surface of the side seat 61, and a T-shaped inner seat 62 is fixed to the front surface of the support seat 63. The T-shaped inner seat 62 is slidably installed in the T-shaped groove 65. The support and limiting structure 6 also includes an adjustment structure 66. The adjustment structure 66 includes an inner movable groove 661 formed inside the T-shaped inner seat 62, and the inner movable groove 661 extends all the way to the interior of the support seat 63. A spring 662 and an inner movable column 663 are installed in the inner movable groove 661. The inner movable column 663 is movably installed in the inner movable groove 661 by the spring 662. The interior of the T-shaped inner seat 62 is relatively... Side plate grooves 668 are provided on both sides of the inner movable groove 661. Side sliding plates 667 are installed within the side plate grooves 668. One end of the side sliding plate 667 is fixed to the inner movable column 663, and a limit block 669 is welded to the surface of the other end of the side sliding plate 667. Multiple limit slots 651 corresponding to the limit blocks 669 are evenly provided vertically on the inner wall of the T-shaped groove 65. The end of the limit block 669 passes through one of the limit slots 651, thus stably limiting the T-shaped inner seat 62, the support 63, and the support block 64. The interior of the support 63 is relative to the inner movable groove 661. Side slides 664 are provided on both sides, and side slide strips 665 are slidably installed in the side slides 664. L-shaped side levers 666 are provided on both sides of the support 63. One end of the side slide strip 665 extends to the side of the support 63 and is fixed to the L-shaped side lever 666. This allows the operator to adjust the height of the support 64 by simply pushing the L-shaped side lever 666, which moves the side slide strip 665 along with the inner movable column 663. The inner movable column 663 gradually compresses the spring 662, causing the side slide plate 667 to move along with the limiting block 669 until the end of the limiting block 669 moves. Once the T-shaped inner seat 62 is no longer limited by the limiting slot 651, it can slide up and down within the T-shaped slide groove 65 to change the height of the support 63 and the support block 64. After adjusting to a suitable support height, release the L-shaped side lever 666. At this time, the spring 662 will push the inner movable column 663 back to its original position, and cause the side slide plate 667 to spring back with the limiting block 669. Finally, the end of the limiting block 669 can be locked into the limiting slot 651 in other positions, and the T-shaped inner seat 62 and the support block 64 can be limited again, completing the rapid adaptive adjustment of the height of the support block 64.

[0025] In this embodiment, preferably, a cylindrical groove is provided inside one end of the inner movable column 663, and one end of the spring 662 is inserted into the cylindrical groove, so that the spring 662 can be limited to a certain extent and prevent the spring 662 from deviating.

[0026] In this embodiment, preferably, the top end of the T-shaped slide 65 extends to the top of the side seat 61, and the bottom end of the T-shaped slide 65 extends to the bottom of the side seat 61, so that the T-shaped inner seat 62 can slide out from either end of the T-shaped slide 65, which facilitates the assembly and disassembly of the T-shaped inner seat 62 and the support block 64.

[0027] Example 2

[0028] Please see Figures 1 to 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that rubber side pads 642 are embedded in the inner walls of both sides of the U-shaped bracket 641, and the side of the rubber side pads 642 is provided with an integrated limiting protrusion 643. Both are made of rubber material and will undergo elastic deformation when squeezed. The end of the limiting protrusion 643 presses on the top surface of the first flushing pipe 51 or the second flushing pipe 52, which can play a certain role in pressing and limiting the first flushing pipe 51 and the second flushing pipe 52, further ensuring the limiting stability of the first flushing pipe 51 and the second flushing pipe 52.

[0029] In this embodiment, preferably, a rectangular mounting groove is provided on both inner walls of the U-shaped bracket 641, and the rubber side pad 642 is installed in the mounting groove, so that the rubber side pad 642 can be embedded in the side wall of the U-shaped bracket 641, so that the rubber side pad 642 itself does not affect the entry and exit of the first flushing pipe 51 and the second flushing pipe 52.

[0030] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
