Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of oil cylinder maintenance, in particular, to a vehicle-mounted hydraulic oil cylinder dismounting and separating device. BACKGROUND

[0002] The hydraulic cylinder of the engineering machinery is the core execution element of the hydraulic system, and its performance directly affects the stability of the entire system. The hydraulic cylinder is mainly composed of a cylinder barrel assembly, a piston assembly, a sealing device, a buffer device and the like, and converts liquid pressure into mechanical energy to drive the load to realize linear or rotary movement. However, during long-term use, the cylinder cover and the cylinder barrel, the piston and the cylinder barrel, and the guide sleeve and the piston rod are prone to rusting, deformation or impurity jamming due to complex working conditions and harsh environments, resulting in difficult dismounting.

[0003] In the prior art, hydraulic cylinder dismounting in the field generally relies on manual operation. For rusted cylinder covers and cylinder barrels, manual methods such as hammering, prying or vehicle pulling are used to forcibly separate them, which can easily cause scratches on the cylinder body, deformation of the piston rod, and even safety accidents such as cylinder barrel bursting. When dismounting the guide sleeve in the field, methods such as manual hammering or air dismounting are not only inefficient, but also can damage critical moving parts and increase maintenance costs. Therefore, manual operation is time-consuming and labor-intensive when hydraulic cylinders are damaged in the field, especially in field operations or emergency maintenance scenarios, which seriously affects the progress of the project.

[0004] Currently, the mainstream large horizontal dismounting machine is only suitable for factory maintenance and is bulky and inconvenient to move, which cannot meet the emergency maintenance needs in remote areas (such as Xinjiang, Tibet, etc.) or field conditions. In such scenarios, the hydraulic cylinder needs to be transported a long distance to the maintenance point, resulting in long maintenance cycle, high cost, and even affecting the execution efficiency of emergency tasks such as field fort construction. CONTENT OF THE INVENTION

[0005] To overcome the above-mentioned defects, embodiments of the present disclosure provide a vehicle-mounted hydraulic oil cylinder dismounting and separating device, which solves the technical problem of inconvenient manual maintenance of hydraulic oil cylinders in the field in the prior art.

[0019] A rotating rod is rotatably mounted on the fixed block. The end of the rotating rod away from the fixed block has a locking part. The rotating rod is arranged so that after rotation, it contacts the side of the sliding block away from the fixed block to prevent the sliding block from moving away from the fixed block.

DETAILED DESCRIPTION

[0030] The present disclosure will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.

[0031] In order to make the drawing simple and clear, only the parts related to the disclosure are shown in the drawings, which do not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0032] In this paper, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0033] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] like Figures 1-2 As shown, in the field of hydraulic cylinder repair technology, to solve the problem of inconvenience in repairing hydraulic cylinders in the field, a vehicle-mounted hydraulic cylinder disassembly and separation device is shown in one embodiment of this disclosure. This device is mainly used to separate the cylinder barrel 1 and piston 2 of the hydraulic cylinder.

[0037] The main structure of the device includes a mounting base 3 and a jacking telescopic component 4. The mounting base 3 serves as a connection and support, and it can be detachably connected to the vehicle, allowing the entire device to be easily moved in the field to meet maintenance needs in different locations. The cylinder 1 to be disassembled is connected to the mounting base 3, which provides a disassembly platform for the cylinder 1.

[0038] There are two push-pull telescopic components 4, symmetrically arranged on the mounting base 3. This symmetrical arrangement ensures that the force applied to the piston 2 is uniform during the separation of the cylinder 1 and piston 2, preventing the piston 2 from tilting or damaging the inner wall of the cylinder 1 due to uneven force. The end of the piston 2 away from the cylinder 1 is connected to the extended end of the push-pull telescopic component 4. The push-pull telescopic component 4 is a component capable of extending and retracting; it can be a hydraulic telescopic rod, an electric telescopic rod, etc. When the push-pull telescopic component 4 receives a drive signal, it begins to extend. Since the piston 2 is connected to the extended end of the push-pull telescopic component 4, the extension of the push-pull telescopic component 4 causes the piston 2 to slide along the inside of the cylinder 1, gradually moving away from the cylinder 1, until the piston 2 is completely separated from the cylinder 1, completing the disassembly work.

[0039] Specifically, when a hydraulic cylinder needs repair in the field, first connect the mounting base 3 to the vehicle, ensuring that the device is not loose or wobbly. Then, install the cylinder barrel 1 of the hydraulic cylinder to be disassembled onto the mounting base 3, ensuring that the cylinder barrel 1 is securely installed. Connect the end of the piston 2 away from the cylinder barrel 1 to the extended end of the jacking telescopic component 4, ensuring a reliable connection so that the force can be effectively transmitted to the piston 2 during the jacking process.

[0040] Then, a drive signal is sent to the push-pull telescopic component 4 to initiate its extension. As the push-pull telescopic component 4 extends, the piston 2 slides along the inside of the cylinder 1 under its influence. During this process, due to the symmetrical arrangement of the push-pull telescopic components 4, the piston 2 experiences a uniform force and can move smoothly away from the cylinder 1. When the push-pull telescopic component 4 extends to a certain extent, the piston 2 completely separates from the cylinder 1, at which point the disassembly of the hydraulic cylinder is completed.

[0041] The advantage lies in the fact that the device achieves portability by connecting the mounting base 3 to the vehicle, solving the problem of inconvenient manual maintenance of hydraulic cylinders in the field in existing technologies. In remote areas or field conditions, workers can carry the device or quickly transport it to the location where maintenance is needed, and promptly disassemble and repair the hydraulic cylinders, greatly improving maintenance efficiency and reducing project delays caused by hydraulic cylinder failures.

[0042] Meanwhile, the symmetrical design of the push-pull telescopic component 4 ensures that the piston 2 is subjected to uniform force during the separation of cylinder 1 and piston 2. Compared with traditional manual disassembly methods, such as hammering, prying, or pulling, this method avoids problems such as cylinder scratches and piston rod deformation caused by uneven force, effectively protecting the key components of the hydraulic cylinder and reducing maintenance costs. Traditional manual disassembly methods are prone to safety accidents such as cylinder 1 exploding, while this device achieves the separation of piston 2 and cylinder 1 through the smooth extension of the push-pull telescopic component 4, avoiding the use of violent disassembly methods, improving operational safety, and ensuring the personal safety of maintenance personnel.

[0043] like Figures 1-2 As shown, to further optimize the adaptability of the vehicle-mounted hydraulic cylinder disassembly and separation device to cylinders 1 of different specifications and installation states, a clamp 5 is added. The clamp 5 is mounted on the mounting base 3 and can slide horizontally along the extension direction of the pushing telescopic member 4. This means that the position of the clamp 5 can be flexibly adjusted according to the actual situation of the cylinder 1. The cylinder 1 is mounted on the mounting base 3 via the clamp 5, which provides a more stable and adjustable mounting method for the cylinder 1. For example, when encountering hydraulic cylinders of different lengths, the position of the cylinder 1 on the mounting base 3 can be reasonably adjusted by sliding the clamp 5 to ensure that the subsequent pushing telescopic member 4 can smoothly separate the piston 2 from the cylinder 1.

[0044] Specifically, first, install the clamp 5 on the mounting base 3, ensuring that the clamp 5 can slide horizontally along the extension direction of the push-pull telescopic member 4. Next, place the cylinder 1 to be disassembled on the mounting base 3. Slide the clamp 5 according to the specific position and size of the cylinder 1, bringing the clamp 5 close to the cylinder 1. During this process, ensure that the sliding direction of the clamp 5 is consistent with the extension direction of the push-pull telescopic member 4 to facilitate subsequent pushing operations. Secure the cylinder 1 to the mounting base 3 using the clamp 5, ensuring that the cylinder 1 is firmly installed and will not shake or shift during subsequent pushing operations. After connecting the clamp 5 and the cylinder 1, activate the push-pull telescopic member 4, causing the piston 2 to separate from the cylinder 1.

[0045] The advantage lies in the fact that the addition of clamp 5, with its horizontal sliding design, greatly improves the adaptability of the device to cylinders 1 of different specifications and installation states. By flexibly adjusting the position of clamp 5, cylinder 1 can be better secured, ensuring its stability during disassembly, thereby improving the accuracy and efficiency of the disassembly work. At the same time, this adjustable design also allows the device to handle more types of hydraulic cylinders, expanding its application range.

[0046] like Figures 1-2 As shown, the clamp 5 includes a sliding seat 51, a sliding block 52, and a connecting rod 53. The sliding seat 51 is horizontally slidably mounted on the mounting base 3, providing a movable base for the entire clamp 5 and allowing for overall position adjustment based on the position of the cylinder 1. The sliding block 52 is slidably mounted on the sliding seat 51, and its sliding direction is perpendicular to the sliding direction of the sliding seat 51. This perpendicular sliding design increases the flexibility of clamp 5 adjustment. The cylinder 1 has a mounting hole 11 at the end away from the piston 2, and the connecting rod 53 is mounted on the sliding block 52. When it is necessary to fix the cylinder 1, the sliding block 52 slides, driving the connecting rod 53 to move, ultimately inserting the connecting rod 53 into the mounting hole 11 of the cylinder 1, thereby limiting the position of the cylinder 1 relative to the sliding seat 51 and achieving a stable installation of the cylinder 1 on the clamp 5.

[0047] Specifically, the sliding seat 51 is installed on the mounting base 3, ensuring that the sliding seat 51 can slide horizontally on the mounting base 3. The sliding block 52 is installed on the sliding seat 51, and the insertion rod 53 is set on the sliding block 52, ensuring that the sliding block 52 can slide on the sliding seat 51. According to the position of the cylinder 1, the sliding seat 51 is slid, so that the clamp 5 is close to the mounting hole 11 of the cylinder 1. The sliding block 52 is slid, so that the insertion rod 53 moves towards the mounting hole 11 of the cylinder 1 and finally inserts into the mounting hole 11, completing the fixation of the cylinder 1 on the clamp 5. Then, the push telescopic component 4 is activated, causing the piston 2 to separate from the cylinder 1.

[0048] The advantage is that this refined clamp 5 structure design, through the double sliding adjustment of sliding seat 51 and sliding block 52, and the fixed way of inserting plug rod 53 into mounting hole 11, can more accurately fix cylinder barrel 1. Double sliding adjustment can adapt to mounting holes 11 of different positions and angles, improving the versatility of clamp 5 to different cylinder barrels 1. At the same time, the fixed way of inserting plug rod 53 into mounting hole 11 is simple and reliable, which can effectively prevent the displacement of cylinder barrel 1 during disassembly, ensuring the smooth progress of disassembly work.

[0049] As shown in Figures 1-2 The clamp 5 also increases the fixed block 54. The fixed block 54 has an insertion hole 55 on the side facing the sliding block 52. When the sliding block 52 slides, the plug rod 53 is inserted into the mounting hole 11 of the cylinder barrel 1, and then continues to slide, the plug rod 53 will penetrate the mounting hole 11 and be inserted into the insertion hole 55 of the fixed block 54. This design further enhances the fixing effect of the cylinder barrel 1 on the clamp 5. By inserting the plug rod 53 into the mounting hole 11 and the insertion hole 55 at the same time, a more stable connection structure is formed, which can better resist various forces generated during disassembly, ensuring that the cylinder barrel 1 remains stable throughout the disassembly process.

[0050] Specifically, the fixed block 54 is installed at the appropriate position to ensure that its insertion hole 55 is on the same axis as the mounting hole 11 of the cylinder barrel 1. When hydraulic cylinder maintenance is required, install sliding seat 51, sliding block 52 and plug rod 53, adjust the position of sliding seat 51, and insert plug rod 53 into the mounting hole 11 of cylinder barrel 1. Continue to slide the sliding block 52, so that the plug rod 53 penetrates the mounting hole 11 of the cylinder barrel 1 and is inserted into the insertion hole 55 of the fixed block 54, further fixing the cylinder barrel 1.

[0051] The advantage is that the design of adding fixed block 54 and insertion hole 55 improves the stability of the fixing of cylinder barrel 1. During disassembly, due to the friction between piston 2 and cylinder barrel 1 and the pushing force of telescopic member 4, cylinder barrel 1 will be subjected to a larger force. By inserting plug rod 53 into mounting hole 11 and insertion hole 55 at the same time, these forces can be effectively dispersed, avoiding the shaking or displacement of cylinder barrel 1 due to uneven force, thereby ensuring the accuracy and safety of disassembly work.

[0052] As shown in Figures 1-2 The number of plug rods 53 is several, and they are of different sizes. The sliding block 52 is rotatably connected with a first rotating frame 56, and the first rotating frame 56 has a plurality of installation faces 561 distributed circumferentially. A plurality of plug rods 53 are connected one by one to the plurality of installation faces 561. When encountering different sizes of mounting holes 11, rotate the first rotating frame 56, so that plug rods 53 of different sizes are sequentially directed towards the mounting hole 11, thereby selecting plug rods 53 of appropriate size to be inserted into the mounting hole 11, realizing the fixation of different sizes of cylinder barrels 1.

[0053] Specifically, the first rotating frame 56 is rotationally connected to the sliding block 52, and the plug-in rods 53 of different sizes are installed on the installation surface 561 of the first rotating frame 56. The size of the installation hole 11 of the cylinder 1 is observed to determine the size of the plug-in rod 53 to be used. According to the size of the plug-in rod 53 required, the first rotating frame 56 is rotated so that the plug-in rod 53 of the appropriate size faces the installation hole 11.

[0054] The advantage is that this design makes the device more versatile. The installation holes 11 of hydraulic cylinders of different specifications may be different in size. By providing plug-in rods 53 of different sizes and switching them using the first rotating frame 56, the device can adapt to installation holes 11 of various sizes, without the need to equip different devices for different sizes of cylinders 1, reducing costs and improving the efficiency of the device.

[0055] As shown in Figures 1-2 In order to better match the plug-in rods 53 of different sizes, the second rotating frame 57 is rotationally connected to the fixed block 54, and the plug-in holes 55 are formed on the second rotating frame 57. The number of plug-in holes 55 matches the size of the plug-in rod 53, and the plug-in holes 55 are arranged circumferentially along the second rotating frame 57. When the first rotating frame 56 is rotated to select a plug-in rod 53 of a different size, the second rotating frame 57 is correspondingly rotated so that the plug-in holes 55 of different sizes are sequentially directed towards the installation hole 11, to adapt to the insertion of plug-in rods 53 of different sizes, ensuring that the plug-in rod 53 can smoothly pass through the installation hole 11 and be inserted into the plug-in hole 55, achieving stable fixation of the cylinder 1.

[0056] Specifically, the second rotating frame 57 is rotationally connected to the fixed block 54. The first rotating frame 56 and the plug-in rod 53 are installed, the size of the installation hole 11 is determined, and the first rotating frame 56 is rotated to select the appropriate plug-in rod 53. According to the size of the selected plug-in rod 53, the second rotating frame 57 is rotated so that the plug-in hole 55 of the appropriate size faces the installation hole 11. The position of the sliding seat 51 and the sliding block 52 is adjusted so that the plug-in rod 53 is inserted into the installation hole 11 of the cylinder 1 and the plug-in hole 55 of the fixed block 54. Then, the push-pull member 4 is started to separate the piston 2 from the cylinder 1.

[0057] The advantage is that the design of the second rotating frame 57 and the plug-in holes 55 of different sizes further improves the adaptability of the device to cylinders 1 of different sizes. Through the cooperation of the first rotating frame 56 and the second rotating frame 57, the appropriate size of the plug-in rod 53 and the plug-in hole 55 can be accurately selected, ensuring that the cylinder 1 can be stably fixed in different sizes, and ensuring the reliability and accuracy of the disassembly work.

[0058] As shown in Figures 1-2As shown, the clamp 5 also includes a rotating rod 58, which is rotatably mounted on the fixed block 54. The end of the rotating rod 58 away from the fixed block 54 has a locking portion 581. When the sliding block 52 slides to insert the insertion rod 53 into the mounting hole 11 and the insertion hole 55, the rotating rod 58 is rotated to contact the side of the sliding block 52 away from the fixed block 54. The locking portion 581 serves to better hold the sliding block 52 in place, preventing it from being pushed away from the fixed block 54 by external forces during disassembly. This ensures that the insertion rod 53 remains inserted into the mounting hole 11 and the insertion hole 55, maintaining the fixing effect of the cylinder 1.

[0059] Specifically, the rotating rod 58 is rotatably mounted on the fixed block 54. After installing and adjusting all components of the clamp 5, the insertion rod 53 is inserted into the mounting hole 11 of the cylinder 1 and the insertion hole 55 of the fixed block 54. The rotating rod 58 is rotated so that its locking part 581 contacts the side of the sliding block 52 away from the fixed block 54, locking the sliding block 52. Then, the push-pull telescopic component 4 is activated, causing the piston 2 to separate from the cylinder 1.

[0060] The advantage lies in the enhanced stability of the clamp 5 due to the design of the rotating rod 58 and the locking part 581. During disassembly, the friction between the piston 2 and the cylinder 1, and the thrust of the push-pull telescopic member 4, may cause slight displacement of the sliding block 52, affecting the fixing effect of the insertion rod 53. By locking the sliding block 52 with the rotating rod 58, this displacement can be effectively prevented, ensuring that the cylinder 1 remains stably fixed throughout the disassembly process, thus improving the safety and reliability of the disassembly work.

[0061] like Figures 1-2 As shown, in order to better maintain the state of the rotating rod 58 in locking the sliding block 52, the clamp 5 also includes a torsion spring. The torsion spring is located at the rotation point of the rotating rod 58, and its two ends act on the fixed block 54 and the rotating rod 58 respectively. The torsion spring provides a force to the rotating rod 58 to rotate closer to the sliding block 52, so that the rotating rod 58 can automatically maintain contact with the sliding block 52 without external interference, further enhancing the fixing effect on the sliding block 52.

[0062] Specifically, a torsion spring is placed at the rotation point of the rotating rod 58, ensuring that its two ends act on the fixed block 54 and the rotating rod 58 respectively. After installing the rotating rod 58 and completing the installation and adjustment of all components of the clamp 5, the insertion rod 53 is inserted into the mounting hole 11 of the cylinder 1 and the insertion hole 55 of the fixed block 54. Rotating the rotating rod 58 engages the sliding block 52. During disassembly, the torsion spring continuously provides force to the rotating rod 58 as it approaches the sliding block 52, ensuring that the rotating rod 58 always engages the sliding block 52.

[0063] The advantage is that the torsion spring setting improves the reliability of the rotating rod 58 fixing the sliding block 52. During disassembly, the rotating rod 58 may be loosened due to factors such as vibration. The continuous force provided by the torsion spring can overcome these interference factors, so that the rotating rod 58 always maintains the clamping state of the sliding block 52, thereby ensuring the fixing effect of the cylinder barrel 1 and further improving the stability and safety of the device.

[0064] As shown in Figures 1-2 , the mounting seat 3 has a plurality of first positioning holes 31 uniformly distributed along the sliding direction of the sliding seat 51, and the sliding seat 51 has a plurality of second positioning holes 511. The clamp 5 also includes a fastener 59, which is inserted through the first positioning hole 31 and the second positioning hole 511 after the sliding seat 51 is slid to the appropriate position, thereby limiting the position of the sliding seat 51 relative to the mounting seat 3. This positioning method can accurately adjust and fix the position of the sliding seat 51 according to the specific position and size of the cylinder barrel 1, ensuring that the clamp 5 can accurately fix the cylinder barrel 1.

[0065] The advantage is that the design of the first positioning hole 31, the second positioning hole 511 and the fastener 59 improves the accuracy of the position adjustment and the stability of the fixation of the sliding seat 51. By selecting different first positioning holes 31 and second positioning holes 511 for cooperation, the position of the sliding seat 51 can be accurately adjusted to adapt to different specifications of the cylinder barrel 1. At the same time, the fixation method of the fastener 59 can effectively prevent the sliding seat 51 from shifting during disassembly, ensuring the fixing effect of the clamp 5 on the cylinder barrel 1 and improving the accuracy and reliability of the disassembly work.

[0066] As shown in Figures 1-2 Figures 1-2 , in order to more conveniently connect the piston 2 with the push telescopic member 4, the device also includes a mounting rod 6. The mounting rod 6 penetrates the two push telescopic members 4 at the extended ends, and the piston 2 is connected with the extended ends of the push telescopic members 4 through the mounting rod 6. This connection method makes the connection between the piston 2 and the push telescopic member 4 more stable, and can ensure that the force exerted by the two push telescopic members 4 on the piston 2 is uniformly transmitted, ensuring that the piston 2 moves smoothly during the pushing process.

[0067] The advantage is that the mounting rod 6 optimizes the connection method of the piston 2 and the push telescopic member 4. Through the connection of the mounting rod 6, the force exerted by the two push telescopic members 4 on the piston 2 is more uniform, avoiding the problem of uneven force on the piston 2 due to unstable connection, thereby ensuring that the piston 2 can slide smoothly during the pushing process, improving the efficiency and accuracy of the disassembly work, and also reducing the damage to the piston 2 and the cylinder barrel 1.

[0068] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure rather than limit the present disclosure.
