[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] In the description of this application, it should be noted that the terms "inner" and "outer" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0026] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0027] The present application provides a hydraulic cylinder disassembly device to solve the problem in the related art that the hydraulic cylinder is difficult to disassemble, resulting in low disassembly efficiency and maintenance efficiency of the hydraulic cylinder.

[0028] See also Figure 1 、 Figure 2A hydraulic cylinder disassembly device includes a base 100 and a frame 200. The base 100 includes a fixing member 130 for fixing the hydraulic cylinder. The frame 200 is mounted on the base 100 and provided with a limit member 230. The limit member 230 is movable relative to the frame 200 and is used to fix a disassembly member. The disassembly member can engage a component to be disassembled in the hydraulic cylinder and be pulled away from the base 100.

[0029] Specifically, when using the hydraulic cylinder disassembly device of this embodiment, an operator moves the hydraulic cylinder requiring maintenance or repair onto the base 100 and secures it using the securing member 130. Once securely secured, the disassembly member is secured to the stopper 230. The operator then moves the stopper 230, causing it to move the disassembly member to the desired position. The operator then continues to manipulate the disassembly member, securing the component to be disassembled from the hydraulic cylinder, namely the piston, to the disassembly member. The operator then uses the disassembly member to pull the piston away from the base 100, thereby removing the piston from the hydraulic cylinder.

[0030] When disassembling a hydraulic cylinder using this embodiment, the operator only needs to move the hydraulic cylinder to a suitable location and operate the disassembly component to complete the disassembly operation. This eliminates the need for multiple operators to coordinate and disassemble the hydraulic cylinder, reducing labor costs and operator workload while also improving the efficiency of disassembly and maintenance of the hydraulic cylinder. Furthermore, the use of the disassembly component to disassemble the piston of the hydraulic cylinder significantly reduces the operational difficulty of the disassembly operation, making it easy to operate and convenient to use.

[0031] Among them, the disassembly part can use different equipment according to actual conditions, as long as the disassembly part can be fixed on the limit part 230 and the piston of the hydraulic cylinder is stretched and disassembled. For example, in this embodiment, the disassembly part can be set as a manual hoist. Manual hoists are common lifting equipment, mainly used for lifting, lowering and moving heavy objects. In this embodiment, the manual hoist is fixed on the limit part 230, and the piston of the hydraulic cylinder is stretched by the manual hoist to remove the piston. During the disassembly process, there is no need to provide additional energy for the manual hoist, making the use process of this embodiment easier to use.

[0032] The stopper 230 is used to secure the disassembly component. In this embodiment, the stopper 230 is configured as a rotating body formed by winding a wire rope or rigid metal, that is, a coil of wire rope or rigid metal. Thus, the stopper 230 is mounted on the crossbar 220 and can move freely on the crossbar 220 or the vertical rod 210. After the disassembly component is fixed to the stopper 230, the stopper 230 can also drive the disassembly component to move freely to the appropriate position for disassembly. The material of the wire rope or rigid metal also ensures that the stopper 230 can provide sufficient support for the disassembly component. That is, after the manual hoist is suspended on the wire rope, the wire rope can ensure the manual hoist is stably suspended. After the disassembly operation begins, the manual hoist also provides an upward pulling force to the piston, which in turn generates a downward reaction force on the wire rope. The wire rope also provides sufficient strength to ensure that the disassembly operation can proceed normally.

[0033] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the frame 200 includes a vertical rod 210 and a horizontal rod 220. The vertical rod 210 is vertically mounted on the base 100, while the horizontal rod 220 is located at the end of the vertical rod 210 away from the base 100. A stopper 230 is disposed on the horizontal rod 220. The vertical rod 210 is vertically mounted on the base 100, providing a stable support structure for the horizontal rod 220 and ensuring that the frame 200 does not shake or tilt during use. The horizontal rod 220 is located at the top of the vertical rod 210, further enhancing the rigidity of the frame 200 and preventing deformation or collapse due to external forces. The vertical arrangement of the vertical rod 210 and the horizontal rod 220 fully utilizes the space above the base 100, avoiding excessive horizontal space occupation. This provides a more spacious operating area, ensures that any type of hydraulic cylinder can be placed on the base 100, and has sufficient space for the disassembly parts to extract the piston in the hydraulic cylinder, thereby improving the structural rationality of this embodiment.

[0034] In one embodiment, for example, Figure 1 、 Figure 2 As shown, at least two vertical rods 210 are provided, and a crossbar 220 is connected to the two vertical rods 210 to form a gantry. The two vertical rods 210 are respectively arranged at both ends of the crossbar 220, which significantly enhances the stability of the entire frame 200. This design prevents the crossbar 220 from shaking or tilting when subjected to external forces, ensuring stability during the disassembly process. The two vertical rods 210 evenly distribute the load on the crossbar 220, reducing the burden on a single vertical rod 210 and preventing deformation or damage caused by uneven force.

[0035] Furthermore, the two vertical rods 210 provide more support points, allowing the operator more space and flexibility during the disassembly process, thereby improving disassembly efficiency and operational convenience. Furthermore, the design of the two vertical rods 210 does not obstruct the operator's line of sight, allowing the operator to clearly see the disassembly opening and the parts to be disassembled, thereby improving the accuracy and efficiency of the operation.

[0036] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the gantry includes a reinforcing rib 240, which is arranged at a position on the gantry away from the base 100. One end of the reinforcing rib 240 is fixedly arranged on the crossbar 220, and the end of the reinforcing rib 240 away from the crossbar 220 is fixedly arranged on the vertical bar 210. The reinforcing rib 240 can significantly enhance the overall rigidity and stability of the gantry, improve the overall structural strength of the frame 200, prevent deformation or shaking caused by external forces during use, and ensure the stability and reliability of this embodiment during the disassembly process. The reinforcing rib 240 can absorb and disperse vibrations, reduce the degree of shaking of the frame 200 during the disassembly operation, thereby reducing the instability factors caused by vibration during the disassembly process and improving the smoothness of the operation. In addition, the reinforcing rib 240 can also prevent the crossbar 220 and the vertical bar 210 from bending or breaking when subjected to external forces, thereby ensuring the safety of the operator.

[0037] It can be understood that in this embodiment, reinforcing ribs 240 are provided at the positions where both ends of the horizontal bar 220 are connected to the vertical bar 210 to ensure that the connection strength between the horizontal bar 220 and the vertical bar 210 is sufficient to support the disassembly operation. At the same time, it also makes the overall structure of this embodiment symmetrical, so that the load can be evenly distributed on the frame 200, thereby improving the bearing capacity of this embodiment.

[0038] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the base 100 includes a fixing plate 110, and a fixing member 130 is arranged on the fixing plate 110. The fixing member 130 includes a clamping plate 131, and the clamping plate 131 is extended in the direction of the cross bar 220. The clamping plate 131 is provided with a clamping groove 132, and the clamping groove 132 can be relatively fixed to the hydraulic cylinder. The clamping groove 132 on the clamping plate 131 can be relatively fixed to the hydraulic cylinder to ensure that the hydraulic cylinder remains stable during the disassembly process and prevents sliding or displacement. When using this embodiment for disassembly work, the side ears of the hydraulic cylinder are usually clamped into the clamping groove 132 so that the hydraulic cylinder and the clamping plate 131 can be relatively fixed, or other suitable positions of the hydraulic cylinder can be clamped into the clamping groove 132 according to actual conditions, as long as the hydraulic cylinder can be stably fixed by the clamping groove 132.

[0039] Providing a clamping groove 132 on the clamping plate 131 can also ensure that the position of the hydraulic cylinder is always in the appropriate position when placed on the fixed plate 110, assisting the operator to locate the position of the hydraulic cylinder, avoiding manual errors caused by the operator's operation, and improving the accuracy of the disassembly process.

[0040] It is understandable that in this embodiment, there is no restriction on the shape of the snap-in groove 132 , and the snap-in groove 132 can be designed into different shapes and sizes to accommodate hydraulic cylinders of different models and specifications, thereby increasing the scope of application of the hydraulic cylinder disassembly device of this embodiment.

[0041] In one embodiment, for example, Figure 1 、 Figure 2 As shown, at least two clip plates 131 are provided on the fixed plate 110, and the two clip plates 131 are provided in parallel, and a gap is provided between the two clip plates 131. The two clip plates 131 can provide multiple fixing points to ensure that the hydraulic cylinder is more stable during the disassembly process, prevent sliding or displacement, and improve the stability of this embodiment. The two clip plates 131 can evenly share the weight of the hydraulic cylinder, reduce the burden of a single clip plate 131, and prevent deformation or damage due to uneven force; it can also ensure that the position of the hydraulic cylinder on the fixed plate 110 is symmetrical, avoid uneven force due to eccentricity, and improve the accuracy of disassembly. Accordingly, such a stable fixing method can reduce the risk of accidents caused by unstable placement of the hydraulic cylinder or uneven force on the clip plates 131, such as parts falling off or sliding, and ensure the safety of operation.

[0042] It should be noted that the snap-on plate 131 can be designed as a modular structure to facilitate disassembly and assembly, reducing assembly time and cost, making this embodiment easier to manufacture. The snap-on plate 131 and the snap-on slot 132 have a relatively simple structure, and the snap-on plate 131 and the fixing plate 110 can also be integrally formed, which can also reduce the difficulty of manufacturing and processing and improve the practicality of this embodiment.

[0043] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the engaging groove 132 is horizontally defined on the engaging plate 131 and extends away from the fixing plate 110 to form an open slot. This horizontal extension of the engaging groove 132 facilitates the engaging of the hydraulic cylinder after it has been moved to the appropriate location, while also ensuring that the engaging groove 132 can restrict the position of the hydraulic cylinder during disassembly, preventing it from moving. This horizontal extension maximizes space, making the entire disassembly device more compact and reducing its overall size for easier storage and transport.

[0044] The opening of the engaging groove 132 further facilitates the operator in engaging or removing the hydraulic cylinder from the engaging groove 132, making this embodiment easy to operate. The opening also prevents dirt from accumulating in the engaging groove 132 due to prolonged use. Even if a small amount of dust or oil remains in the engaging groove after disassembly, it is easy to clean.

[0045] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the extending directions of the clamping grooves 132 on the two clamping plates 131 are arranged relative to each other. The extending directions of the clamping grooves 132 on the two clamping plates 131 are arranged relative to each other, which can provide two-way fixing points to ensure that the hydraulic cylinder is more stable during the disassembly process and prevent sliding or displacement. If the two clamping grooves 132 are oriented in the same direction, then after the hydraulic cylinder is installed in the clamping groove 132, as long as the hydraulic cylinder is subjected to a force and has a tendency to move toward the opening direction of the clamping groove 132, the hydraulic cylinder may be disengaged from the clamping groove 132. The two clamping grooves 132 are arranged relative to each other, which can improve the reliability of the clamping groove 132 in fixing the hydraulic rod, thereby improving the reliability of this embodiment, preventing accidents during the disassembly process and affecting the normal disassembly operation.

[0046] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the base 100 includes an extension plate 120, which is arranged at the edge of the fixed plate 110 and extends away from the fixed plate 110 to support the fixed plate 110. The extension plate 120 increases the support points of the fixed plate 110, making the fixed plate 110 more stable during the disassembly process, avoiding the "top-heavy" situation of this embodiment, that is, avoiding the excessive weight of the frame 200, which would cause the entire embodiment to slide, shift, or shake. The extension plate 120 can also evenly distribute the load on the fixed plate 110 over a larger area, reducing stress concentration at a single point and extending the service life of the fixed plate 110.

[0047] It should be noted that in actual use, the extension plate 120 can be adaptively positioned according to different ground conditions. In other words, even if the ground is uneven, the position of the extension plate 120 can be adjusted to ensure the levelness and stability of the fixed plate 110. This allows the hydraulic cylinder disassembly device of this embodiment to adapt to different terrains and environments, thereby improving the applicability of this embodiment.

[0048] In one embodiment, for example, Figure 1 、 Figure 2As shown, at least two extension plates 120 are provided on the fixed plate 110. Both extension plates 120 are provided at the ends of the fixed plate 110 and are spaced apart from each other. The two extension plates 120 are spaced apart from each other to ensure that the fixed plate 110 is symmetrically positioned on the fixed plate 110, improving overall balance and preventing uneven force caused by asymmetry.

[0049] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0050] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
