Abstract
Description
Technical Field
[0001] This invention relates to the field of hydraulic cylinder repair technology, specifically to a controllable hydraulic cylinder turning mechanism and a hydraulic cylinder turning and wheel axle disassembly equipment. Background Technology
[0002] In the maintenance of large-scale water conservancy facilities such as hydropower stations, hydraulic cylinders, as the core driving components of hydraulic gate hoists, need to be disassembled and inspected regularly.
[0003] In related technologies, for hydraulic cylinder disassembly operations, when the cylinder body needs to be flipped over to inspect or disassemble components on the other side, the common methods used are direct binding with steel wire ropes or support with simple brackets. These traditional methods suffer from serious safety hazards because steel wire rope binding makes it difficult to precisely control the hydraulic cylinder's center of gravity. During lifting and flipping, the cylinder body is prone to swaying, rotating, or even slipping. Simple brackets only provide unstable support from the bottom and cannot effectively restrain the cylinder body's posture during flipping, causing it to tilt. These problems can lead to damage to the hydraulic cylinder and its internal precision parts during disassembly due to collisions and scratches, reducing maintenance efficiency, increasing maintenance costs, and potentially affecting the operational reliability of the repaired hydraulic cylinder due to hidden damage to parts. Summary of the Invention

The three together form a working platform, which allows the fixing, turning, disassembly and subsequent maintenance of the hydraulic cylinder to be completed continuously on the same equipment. This optimizes the work process, improves work efficiency, and reduces the risk of equipment transportation and the difficulty of personnel operation.
[0017] In some embodiments, the support assembly includes a fixed base, a lifting cylinder, a lifting platform, and a support unit; the mounting end of the lifting cylinder is fixed on the fixed base, the driving side of the lifting cylinder is connected to the lifting platform, and the support unit is mounted on the lifting platform.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.
[0036] According to embodiments of the present invention, in one aspect, a hydraulic cylinder-controlled turning mechanism is provided, such as... Figure 1 and Figure 2 As shown, the controllable turning mechanism includes a connecting platform 5, a turning component 9, a fixing unit, and a lifting drive unit. The turning component 9 is located below the connecting platform 5. The fixing unit is installed on the turning component 9. The lifting drive unit is connected between the connecting platform 5 and the turning component 9. The lifting drive unit is suitable for driving the turning component 9 and the fixing unit on it to rise and fall.
[0037] In this embodiment, the fixing unit includes a first fixing member and two second fixing members; any one of the fixing members is suitable for fixing the hydraulic cylinder; the first fixing member is located at the bottom center of the turning assembly 9, and the first fixing member is used to fix the center of gravity of the hydraulic cylinder; the two second fixing members are symmetrically arranged on both sides of the first fixing member, and the two second fixing members are used to fix the two ends of the hydraulic cylinder; the first fixing member and the two second fixing members together form a three-point support structure.
[0038] In specific embodiments, such as Figure 6 As shown, the turning assembly 9 includes a fixed platform 901 and two sliding platforms 902; the two sliding platforms 902 are fixed to both sides of the top of the fixed platform 901; the first fixing member is a first fixing hook 908 vertically fixed to the middle of the bottom end of the fixed platform 901; the two second fixing members are second fixing hooks 909 respectively installed on the fixed platform 901 through two fixing seats 905. In this solution, the first fixing member and the second fixing member are set as fixing hooks, which can quickly and securely hook the hydraulic cylinder. This is applicable to hydraulic cylinders with lifting lugs, flanges, or other structures on their outer surface; the first fixing hook 908 is directly fixed to the fixed platform 901, and the second fixing hook 909 is set on the fixed platform 901 through the fixing seat 905; the two sliding platforms 902 are fixedly set to the fixed platform 901. The connection structure is simple, the force transmission is reliable, and it is easy to manufacture and install. It can provide a stable load-bearing point for the hydraulic cylinder and ensure the reliability of the three-point support structure.
[0039] In the specific implementation operation, first operate the equipment to align the first fixed hook 908 with and hook the lifting point at the center of gravity of the hydraulic cylinder, and then adjust the position of the equipment so that the two second fixed hooks 909 hook the lifting points at both ends of the hydraulic cylinder respectively, thus completing the three-point fixation.
[0040] In an exemplary embodiment, the lifting drive unit includes two lifting modules, which are arranged at intervals; such as Figure 6 As shown, each lifting module includes a drive motor 912, a take-up roller 911, and a wire rope 907. The drive motor 912 is fixedly mounted on the connecting platform 5, and its output shaft is connected to the take-up roller 911. One end of the wire rope 907 is wound around the take-up roller 911, and the other end passes over the connecting wheel 906 located at the top of the fixed base 905 and is connected to the tilting assembly 9. In this scheme, the lifting drive unit includes two independently controlled lifting modules. The lifting modules achieve smooth lifting through the cooperation of the drive motor 912, the take-up roller 911, and the wire rope 907. The two lifting modules can adjust the two ends of the hydraulic cylinder separately, facilitating precise leveling before tilting.
[0041] In practical implementation, the drive motor 912 is equipped with a servo motor, which drives the winding roller 911 to rotate forward or reverse, thereby winding or releasing the wire rope 907. The connecting wheel 906 serves to guide and change the direction of the wire rope 907, converting the horizontal winding and unwinding motion into vertical lifting or lowering of the tilting assembly 9. The two lifting modules can operate synchronously to achieve overall lifting, or they can operate independently to adjust the height of one end of the hydraulic cylinder, thereby achieving controllable and smooth tilting of the cylinder around its axis during the tilting process, for example, tilting from a horizontal position to a position with the other side facing upward, facilitating comprehensive maintenance.
[0042] In specific embodiments, such as Figure 6 As shown, the sliding platform 902 is equipped with several first pulleys 903, which are located on the side of the sliding platform 902 opposite to the lifting drive unit; the fixed platform 901 is equipped with several second pulleys 904, which are located on the side of the fixed platform 901 opposite to the lifting drive unit. The first pulleys 903 are located on the outer side of the sliding platform 902, and the second pulleys 904 are located on the outer side of the fixed platform 901. These first pulleys 903 and second pulleys 904 cooperate with external guide rails or support surfaces during the turning process to guide the direction of movement, reduce friction, and facilitate smoother and more controllable turning movements.
[0043] When the hydraulic cylinder is raised to the appropriate height and needs to be moved or fine-tuned in the plane, the first pulley 903 and the second pulley 904 can contact the track on the ground side or a flat and solid ground, so that the entire turning assembly 9 and its loaded hydraulic cylinder can be easily pushed laterally, which facilitates the transfer of the hydraulic cylinder from the disassembly station to the turning station or maintenance station, and improves the flexibility of equipment layout and operation process.
[0044] In specific embodiments, such as Figure 6 As shown, a fixing reinforcement pile 910 is fixedly provided at the bottom of the fixing platform 901. The fixing reinforcement piles 910 are spaced apart on the side of the second fixing member away from the first fixing member. The fixing reinforcement piles 910 help to enhance the local structural strength of the installation area of the second fixing member, avoid deformation when hoisting heavy and large hydraulic cylinders, and improve the overall load-bearing capacity.
[0045] Specifically, the fixed reinforcing pile 910 is set as a reinforcing rib or short column extending downward perpendicular to the fixed platform 901. The fixed reinforcing pile 910 is integrally formed with the fixed platform 901 or connected by welding or bolts. It is used to resist the bending moment and local stress concentration generated by the second fixed hook 909 on the fixed platform 901 when it is under heavy load, thus ensuring the structural safety and reliability for long-term use.
[0046] The hydraulic cylinder controllable tilting mechanism provided in this embodiment forms a stable and reliable three-point support structure through a first fixing member set at the bottom center of the tilting assembly 9 and two second fixing members symmetrically distributed on both sides. With the center of gravity and both ends of the hydraulic cylinder fixed at the same time, the lifting drive unit drives the hydraulic cylinder to lift and tilt as a whole. Compared with the traditional method of binding with steel wire rope 907 or simple bracket support, the three-point support structure can effectively constrain the fixed posture of the hydraulic cylinder from above, preventing the hydraulic cylinder from swinging, rotating, slipping or tilting during the lifting and tilting process, thus improving the safety of operation. At the same time, it avoids damage to the hydraulic cylinder and its internal parts due to collision and scratch, thereby ensuring maintenance efficiency and the reliability of equipment operation after repair.
[0047] According to an embodiment of the present invention, in another aspect, a hydraulic cylinder tilting and wheel axle disassembly device is also provided, such as... Figure 1 and Figure 2 As shown, the device includes the aforementioned hydraulic cylinder controllable tilting mechanism, disassembly frame 2, and support assembly 1. The disassembly frame 2 is fixedly installed on one side of the connecting platform 5 in the hydraulic cylinder controllable tilting mechanism. The disassembly frame 2 is used to accommodate and position the hydraulic cylinder to be disassembled. The support assembly 1 is movably and vertically arranged at the bottom of the disassembly frame 2. The support assembly 1 is used to support the disassembly frame 2 from below.
[0048] In this embodiment, the controllable turning mechanism, disassembly frame 2, and support component 1 are integrated into a complete disassembly device. The disassembly frame 2 provides sufficient space for the hydraulic cylinder to be accommodated and positioned. The support component 1 supports and stabilizes the disassembly frame 2 from the bottom. The three components together form a working platform, which allows the fixing, turning, disassembly, and subsequent maintenance operations of the hydraulic cylinder to be completed continuously on the same device. This optimizes the work process, improves work efficiency, and reduces the risk of equipment transportation and the difficulty of personnel operation.
[0049] In specific embodiments, such as Figure 3 As shown, the support assembly 1 includes a fixed base 101, a lifting cylinder 102, a lifting platform 103, and a support unit 104. The mounting end of the lifting cylinder 102 is fixed to the fixed base 101, and the drive side of the lifting cylinder 102 is connected to the lifting platform 103. The support unit 104 is mounted on the lifting platform 103. By driving the lifting platform 103 through the lifting cylinder 102, the height of the support assembly 1 can be quickly and accurately adjusted, thereby adapting to the support height requirements of hydraulic cylinders of different sizes. It also allows for flexible adjustment of the height position of the disassembly frame 2 during disassembly, improving operational convenience.
[0050] The lifting cylinder 102 is specifically controlled by an external pneumatic control system, and the operator can control the lifting platform 103 to rise and fall through the valve. Before placing the hydraulic cylinder, the support assembly 1 can be raised to a suitable height so that the disassembly frame 2 is at a height that is easy to operate; when it is necessary to perform bottom operations or disassemble the piston rod, the support assembly 1 can be lowered appropriately to leave space for operation.
[0051] In specific embodiments, such as Figure 4 As shown, the support unit 104 includes a support platform 1041, an angle adjustment shell 1043, a height platform 1045, a baffle 1046, a clamping plate 1047, and a lead screw 1048. The support platform 1041 is fixed on the lifting platform 103. The angle adjustment shell 1043 is fixed at the top center of the support platform 1041. An angle rod 1044 is rotatably connected inside the angle adjustment shell 1043. The height platform 1045 is fixed at the top of the angle rod 1044. The baffle 1046, clamping plate 1047, and lead screw 1048 are arranged in pairs. The two baffles 1046 are arranged opposite each other and fixed on both sides of the top of the height platform 1045. The two clamping plates 1047 are respectively arranged inside the two baffles 1046. The two lead screws 1048 are respectively threaded into one baffle 1046. The end of the lead screw 1048 is rotatably connected to its corresponding clamping plate 1047. Under external force, the two lead screws 1048 are adapted to rotate, correspondingly driving the two clamping plates 1047 to move towards or away from each other to clamp or release the disassembly frame 2. By rotating the lead screws 1048 to drive the two clamping plates 1047 to move towards or away from each other, the sides of the disassembly frame 2 can be clamped or released. This design can provide reliable lateral restraint from both sides, preventing the disassembly frame 2 from lateral displacement or swaying during operation. Through the cooperation of the angle adjustment shell 1043 and the angle rod 1044, the height platform 1045 can be adaptively adjusted within a certain angle range, thereby better fitting with the bottom of the disassembly frame 2, which is beneficial to enhancing the stability and adaptability of the support.
[0052] In actual operation, after the disassembly frame 2 is placed in place, the operator uses a wrench or crank to rotate the lead screws 1048 on both sides. The lead screws 1048 are threadedly engaged with the baffle 1046, and the ends of the lead screws 1048 are rotatably connected to the clamping plates 1047. By rotating the lead screws 1048, the clamping plates 1047 are pushed to move in a straight line. The two clamping plates 1047 move towards each other until they are tightly pressed against the upright plates 21 on both sides of the disassembly frame 2, thus forming a firm lateral clamp. The rotational capability of the angle rod 1044 within the angle adjustment housing 1043 allows for large-area contact through adaptive adjustment even if there is a slight misalignment between the bottom of the disassembly frame 2 and the top of the height platform 1045, ensuring stable support.
[0053] In a specific embodiment, connecting springs 1042 are fixedly installed on both sides of the top of the support platform 1041, with the top of the connecting springs 1042 connected to the bottom of the height platform 1045. The added connecting springs 1042 provide an elastic connection between the support platform 1041 and the height platform 1045 to absorb and buffer vibrations or impact loads that may occur during disassembly operations, protecting the support assembly 1 and its upper mechanism. They also help the height platform 1045 maintain positional stability after angle adjustment and assist in its reset, thus improving the equipment's vibration resistance and operational stability. The connecting springs 1042 are in a pre-compressed state under normal conditions, providing a certain upward supporting force and allowing the height platform 1045 to undergo slight elastic deflection when subjected to lateral forces. When the external force disappears, the springs help the height platform 1045 return to its initial centered position, improving the equipment's adaptability and durability.
[0054] In a specific embodiment, the disassembly frame 2 includes two opposing upright plates 21 and multiple length rods 22 connected between the two upright plates 21. Limiting components 4 are provided on both sides of the inner wall of the disassembly frame 2. The disassembly frame 2 adopts a frame structure combining upright plates 21 and length rods 22, which provides a wide operating space for the hydraulic cylinder, facilitating tool entry and exit and personnel observation and operation. It is lightweight and has good rigidity. The limiting components 4 provided on both sides of the inner wall of the frame can be used to laterally position and assist in fixing the hydraulic cylinder placed in the frame, preventing it from moving adversely during operation. After the hydraulic cylinder is hoisted into the disassembly frame 2, its cylinder body is placed between the two upright plates 21. The limiting components 4 can extend from both sides to contact and abut against the outer shell of the hydraulic cylinder, preventing it from rolling or moving due to force when disassembling internal piston rods and other parts, thus providing a stable foundation for precision disassembly operations.
[0055] In specific embodiments, such as Figure 2 and Figure 7 As shown, the limiting assembly 4 includes a horizontally arranged screw 41 and a limiting shell 42 sleeved on the screw 41. The limiting shell 42 is threadedly engaged with the screw 41, and a fixing screw 43 is provided on the limiting shell 42 to lock the limiting shell 42 onto the screw 41. The limiting assembly 4 uses a threaded engagement, allowing the limiting shell 42 to move flexibly on the screw 41 and adjust its extension length to accommodate hydraulic cylinders of different widths. The fixing screw 43 securely locks the limiting shell 42 in the desired position, ensuring a reliable limiting effect.
[0056] During adjustment, first loosen the fixing screw 43, then rotate the limiting shell 42. Due to the action of the internal and external threads, the limiting shell 42 will move axially along the screw 41. When the buffer pad or contact surface on the inner side of the limiting shell 42 contacts the hydraulic cylinder housing and an appropriate preload is applied, tighten the fixing screw 43 to secure the limiting shell 42 to the current position of the screw 41, thus completing the lateral limiting of the hydraulic cylinder.
[0057] In specific embodiments, such as Figure 2 and Figure 5 As shown, several lifting components 3 are installed on the top of the dismantling frame 2. The lifting components 3 include a mounting base 31 fixed to the dismantling frame 2, a lifting seat 33 fixed on the mounting base 31, and a lifting ring 32 rotatably connected to the lifting seat 33. The lifting components 3 can be easily connected to external hoisting equipment through the lifting ring 32, which facilitates the transfer and workstation adjustment of the entire dismantling equipment and improves the mobility and efficiency of the equipment.
[0058] like Figure 2 As shown, when the equipment needs to be used in different maintenance areas, simply hook the four lifting rings 32 with the hook of the external lifting equipment to smoothly lift and transport the entire hydraulic cylinder flipping and wheel axle disassembly equipment to the new work position. There is no need for cumbersome disassembly and reassembly, which can realize the rapid deployment of the equipment.
[0059] In specific embodiments, such as Figure 1 and Figure 2 As shown, the disassembly equipment also includes a limiting frame 6, which is located on the side of the connecting platform 5 near the disassembly frame 2. A flushing block 7 is fixedly installed inside the limiting frame 6, and a through-hole flushing port 8 is provided on the flushing block 7. The flushing block 7 and flushing port 8 on the limiting frame 6 add auxiliary maintenance functions to the equipment, allowing for high-pressure flushing of disassembled components such as axles at the disassembly station to remove surface rust and dirt. This integrates disassembly and preliminary maintenance, which helps expand equipment functionality and improve overall maintenance efficiency.
[0060] In operation, the flushing block 7 can be fitted with a high-pressure resistant pipe joint or quick-connect interface, which can be quickly connected to the pipeline of an external high-pressure cleaner or lubrication system. The disassembled axle can be temporarily placed at the limit frame 6. By aiming the high-pressure water gun or nozzle at the flushing port 8, the parts can be partially or completely cleaned and rusted. Oil and debris are collected in the oil tray below, keeping the working environment clean and achieving a seamless connection between disassembly and maintenance procedures.
[0061] The hydraulic cylinder tilting and axle disassembly device provided in this embodiment operates as follows: First, the equipment is transferred to the work area via the hoisting assembly 3. The support assembly 1 is operated, and the height is adjusted using the lifting cylinder 102. The rotating screw 1048 drives the clamping plate 1047 to firmly clamp the dismantling frame 2 from both sides, ensuring the stability of the entire work platform. Then, external lifting equipment is used to hoist the hydraulic cylinder to be repaired into the dismantling frame 2 and place it on the support surface. Next, the limiting shells 42 in the limiting assemblies 4 on both sides of the dismantling frame 2 are adjusted to contact and abut against the cylinder body, preventing it from rolling or shifting during subsequent operations. Then, the controllable tilting mechanism of the hydraulic cylinder is operated, and its position is adjusted so that the first fixing member hooks onto the lifting point at the center of gravity of the hydraulic cylinder. Then, the two second fixing members hook onto the lifting points at both ends of the hydraulic cylinder, completing a stable three-point fixation. The lifting drive unit is started, synchronously controlling the two lifting modules to smoothly lift the hydraulic cylinder, allowing it to detach from the support of the dismantling frame 2.
[0062] Then, in the state of hydraulic cylinder suspension, by controlling two lifting modules, one lifting module lifts and the other lifting module slowly descends in sync, driving the hydraulic cylinder to rotate smoothly and controllably around its axis; wherein, the pulleys set on the sliding table 902 and the fixed table 901 can provide auxiliary guidance.
[0063] After flipping the hydraulic cylinder to the desired working position, it can be lowered again and placed on the disassembly frame 2 for disassembly operations. For disassembled parts such as axles, they can be placed on the limiting frame 6 on the side of the equipment, and connected to the external high-pressure cleaning equipment to the flushing port 8 of the flushing block 7 for flushing and initial maintenance.
[0064] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
