Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment maintenance technology, specifically to an auxiliary tool for disassembling and assembling a hydraulic filter cylinder. Background Technology

[0002] The hydraulic filter is installed on the hydraulic lines of the hydraulic station. Its function is to filter various impurities in the hydraulic system. The oil inlet and outlet of the hydraulic filter base are connected to the hydraulic lines. The hydraulic filter cylinder is fixed to the hydraulic filter base downwards by a threaded connection. It contains a filter element, which needs to be replaced regularly. When replacing the filter element, the hydraulic filter cylinder needs to be disassembled and reassembled. Because the hydraulic filter cylinder is a thick-walled steel cylinder with a smooth cylindrical surface, it is easy to fall off if not gripped firmly when disassembling and reassembling, which poses a certain safety risk. During installation, two people are needed to lift and rotate the hydraulic filter cylinder for reassembly. Since the hydraulic filter cylinder and the hydraulic filter base are connected by threads, lifting and reassembling is very inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary tool for disassembling and assembling hydraulic filter cylinders, so as to solve the problems of insufficient support and difficulty in assembly during the disassembly and assembly of hydraulic filter cylinders mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A hydraulic filter cartridge assembly / disassembly auxiliary tool includes a fixed base, which includes a fixed base plate. A fixed tube is vertically mounted on the fixed base plate, and an ear plate is provided on the outer wall of the fixed tube. An adjusting bolt is vertically threaded through the ear plate and is connected to the ear plate by a thread. The adjusting bolt passes through the ear plate from bottom to top. A disassembly support is mounted in a fixed rod, which includes a movable rod and a bearing support. The movable rod is slidably connected to the fixed tube, and the upper end of the movable rod is connected to the bearing support. A rolling bearing is mounted on the bearing support, and the central axis of the rolling bearing is set in the vertical direction. Through the synergistic effect of the fixed base and the rolling bearing, reliable mechanical support is provided for the hydraulic filter cartridge, completely eliminating the risk of the hydraulic filter cartridge falling off due to insufficient grip during traditional assembly / disassembly, and significantly reducing operational safety hazards.

[0006] Furthermore, the adjusting bolt is inserted through the ear plate from bottom to top; by setting the adjusting bolt from bottom to top, it is easier to move the bolt up and down.

[0007] Furthermore, the bearing support is a plate-shaped structure, and a barrier is provided on the upper part of the bearing support. The barrier is located around the rolling bearing and is arranged circumferentially with the rolling bearing as the center. It is used to restrict the movement of the rolling bearing, and the bearing support and the barrier form a cavity with an upper opening.

[0008] Furthermore, the upper edge of the enclosure is flush with the upper edge of the rolling bearing, and two fixing bolts are provided on the enclosure to fix the outer ring of the rolling bearing. The fixing bolts are symmetrically arranged on the left and right sides of the enclosure. By setting the fixing bolts, the movement of the outer ring of the rolling bearing is further restricted, so as to avoid accidental fall caused by the displacement of the rolling bearing.

[0009] Furthermore, the upper end face of the bearing support is provided with a rotating groove, which is opened in the vertical direction. The opening of the rotating groove is circular, and the axis of the rotating groove is on the same straight line as the axis of the rolling bearing. The diameter of the rotating groove is larger than the outer diameter of the inner ring of the rolling bearing and smaller than the outer diameter of the outer ring of the rolling bearing. The inner ring of the rolling bearing rotates synchronously with the hydraulic filter cylinder. Combined with the rotating groove design, frictional resistance is reduced, making thread alignment smoother and shortening the disassembly and assembly time.

[0010] Furthermore, there are two ear plates, which are symmetrically arranged on both sides of the fixed tube: by setting symmetrical ear plates, the bearing support can be prevented from shifting when it is lifted by the adjusting bolt.

[0011] Furthermore, the length of the adjusting bolt is greater than the length from the ear plate to the top of the fixed tube; so that when the adjusting bolt moves upward, it can push the bearing support to move upward synchronously.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Improved operational safety: The fixed guide seat and rolling bearing work together to provide stable support for the hydraulic filter cylinder, avoiding the risk of the hydraulic filter cylinder falling off due to insufficient grip during traditional disassembly and assembly, and significantly reducing operational safety hazards.

[0014] 2. Simplified assembly and disassembly process: The height of the movable support is dynamically adjusted by adjusting bolts, and the rolling bearing rotates with the hydraulic filter cylinder to achieve precise thread alignment. No multiple people are needed to lift and move it. Two people can complete the rotation and auxiliary adjustment of the hydraulic filter cylinder, which greatly improves the work efficiency.

[0015] 3. Enhanced adaptability and versatility: The tool's height-adjustable design can accommodate hydraulic filter cylinders of different sizes. Its simple structure and convenient operation make it suitable for disassembly and assembly of similar filters in other hydraulic stations. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figs. 1-3 As shown, a hydraulic filter cylinder assembly / disassembly auxiliary tool includes a fixed base, which includes a fixed base plate 1. A fixed tube 2 is vertically mounted on the fixed base plate 1. Two ear plates 3 are provided on the outer wall of the fixed tube 2. The two ear plates 3 are symmetrically arranged on both sides of the fixed tube 2. An adjusting bolt 4 is vertically screwed into each ear plate 3. The adjusting bolt 4 passes through the ear plate 3 from bottom to top. By setting the adjusting bolt 4 from bottom to top, it is easier to move the bolt up and down. The length of the adjusting bolt 4 is greater than the length from the ear plate 3 to the top of the fixed tube 2, so that when the adjusting bolt 4 moves upward, it can push the bearing support 6 to move upward synchronously. A disassembly support is installed through the fixed rod. The disassembly support includes a movable rod 5 and a bearing support 6. The movable rod 5 is slidably connected inside the fixed tube 2 and can move up and down along the fixed tube 2. The bearing support 6 is horizontally mounted on the upper end of the movable rod 5. The bearing support 6 is circular. The movable rod 5 is connected to the center of the lower side of the bearing support 6. The bearing support 6 is a horizontally arranged circular plate structure. A retaining wall 7 is provided on the upper part of the bearing support 6. The retaining wall 7 is circumferentially arranged around the outer edge of the rolling bearing 8, with the upper edge of the retaining wall 7 flush with the upper edge of the rolling bearing 8. The bearing support 6 and the retaining wall 7 form a cavity with an upper opening. The rolling bearing 8 is placed horizontally inside the cavity. Two fixing bolts 10 are provided on the retaining wall 7, which are arranged opposite each other on both sides of the retaining wall 7 to fix the outer ring of the rolling bearing 8.

[0022] The central axis of the rolling bearing 8 is set vertically. A rotating groove 9 is provided in the center of the upper end face of the bearing support 6. The rotating groove 9 reduces the friction between the inner ring of the rolling bearing 8 and the upper end face of the bearing support 6, making it easier to disassemble the hydraulic filter cylinder 11. The rotating groove 9 is opened vertically and has a circular opening. The axis of the rotating groove 9 is on the same straight line as the axis of the rolling bearing 8. The diameter of the rotating groove 9 is larger than the outer diameter of the inner ring of the rolling bearing 8 but smaller than the outer diameter of the outer ring of the rolling bearing 8. The outer ring of the rolling bearing 8 is overlapped on the upper end face of the bearing support 6, so that the inner ring of the rolling bearing 8 is suspended above the rotating groove 9.

[0023] In use, place the fixing base 1 horizontally near the hydraulic filter base 12, ensuring the fixing pipe 2 is vertical and stable. Adjusting bolts 4 are inserted from bottom to top onto the two lugs 3 on the outer wall of the fixing pipe 2, ensuring the adjusting bolts 4 can rotate and move vertically. Insert the movable rod 5 into the fixing pipe 2, allowing it to slide freely axially. The upper end of the movable rod 5 is horizontally connected to a bearing support 6, with a circular rotating groove 9 at the center of the upper surface of the bearing support 6. Place the rolling bearing 8 horizontally on the bearing support 6, ensuring its central axis coincides with the axis of the rotating groove 9. The outer diameter of the inner ring of the rolling bearing 8 is smaller than the diameter of the rotating groove 9, while the outer diameter of the outer ring is larger than the diameter of the rotating groove 9, to prevent friction between the inner ring and the rotating groove 9. A retaining wall 7 is installed on the upper part of the bearing support 6, and the outer ring of the rolling bearing 8 is locked with fixing bolts 10 on the retaining wall 7 to prevent rotation. Rotate the adjusting bolts 4 on both sides to push the movable rod 5 up to a position close to the bottom of the hydraulic filter cylinder 11, leaving space for subsequent fine adjustments.

[0024] When disassembling the hydraulic filter housing 11, move this utility model directly below the hydraulic filter housing 11, ensuring the base plate 1 is parallel to the hydraulic filter base 12. Slowly rotate the adjusting bolt 4, moving it upwards until its end abuts against the lower side of the bearing support 6. Continue moving the adjusting bolt 4 to raise the bearing support 6 axially along the fixed tube 2 until the upper edge of the inner side of the inner ring of the rolling bearing 8 is in complete contact with the lower arc surface of the hydraulic filter housing 11, forming a stable support. The operator rotates to disassemble the hydraulic filter housing 11. The inner ring of the rolling bearing 8 rotates synchronously with the hydraulic filter housing 11. Simultaneously, the adjusting bolt 4 is rotated to gradually lower the height of the movable rod 5, ensuring the hydraulic filter housing 11 remains supported during the thread disassembly process, preventing it from falling off or shifting.

[0025] When installing the hydraulic filter housing 11, move the adjusting bolt 4 downwards until the end of the adjusting bolt 4 no longer abuts against the bearing support 6, and the bearing support 6 returns to its lowest height. Then, place the new hydraulic filter housing 11 on the rolling bearing 8, ensuring that the upper edge of the inner side of the inner ring of the rolling bearing 8 is in complete contact with the lower arc surface of the hydraulic filter housing 11. Align the top of the hydraulic filter housing 11 with the threaded interface of the hydraulic filter base 12, move the adjusting bolt 4 upwards, gradually raise the height of the movable rod 5, and simultaneously rotate the hydraulic filter housing 11 to assist in the precise alignment of the hydraulic filter housing 11 and the threads of the hydraulic filter base 12 until it is fully tightened.

[0026] Through the synergistic action of the fixed seat and the adjusting bolt 4, combined with the follow-up support of the rolling bearing 8, a stable and dynamically adjustable support force is provided for the hydraulic filter housing 11, completely eliminating the risk of the hydraulic filter housing 11 falling off. The rotating groove 9 provided on the bearing support 6, combined with the rolling bearing 8, significantly reduces rotational resistance, making thread alignment more precise and operation less strenuous.

[0027] This invention replaces traditional manual lifting, reducing safety hazards and shortening operation time. The height-adjustable structure supports hydraulic filter cylinders 11 of different sizes and can be extended to maintenance scenarios for similar hydraulic filters, improving tool versatility.
