Detailed Implementation

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified. In the description of this application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular, for example, the range of included angles between 80° and 100° is considered perpendicular. Similarly, "parallel" means completely parallel or almost completely parallel, for example, the range of completely parallel angles between 10° is considered parallel.

[0057] As a crucial component of diesel engines, the gear pump's function is to provide sufficient and appropriate amounts of coolant or lubricating oil, ensuring the engine operates within a relatively efficient temperature range. Its performance directly impacts the engine's operation and reliability. During engine testing, different gear pump designs are employed to verify their effects on engine performance, necessitating frequent disassembly and reassembly of the gear pump. Furthermore, in real-world marine applications, disassembly and reassembly are required for diesel engine maintenance. The gear pump connects to external cooling and lubricating pipes, and also to the diesel engine or its components. Above the gear pump are other components such as the lubricating oil module, temperature control valve box, oil-water distribution box, and oil cooler. Current disassembly and reassembly methods involve disconnecting the gear pump's inlet and outlet bolts, securing the outlet with slings, removing the bolts binding the gear pump to the engine body, manually separating the gear pump from the engine body, and then using a crane to lift the gear pump away. However, due to the gear pump's irregular shape, it's difficult to properly straighten it, posing certain safety hazards during disassembly. During reassembly, it cannot be installed upright by hoisting; a crane must be used in conjunction. If the upright method is used for disassembly and assembly, the components directly above the gear pump must be completely removed, inevitably increasing labor costs and the cost of replacing vulnerable parts. If the gear pump slips, there is a safety risk to the assembly personnel, assembly efficiency is low, and quality is uncontrollable.

[0058] In view of this, embodiments of this application provide a diesel engine gear pump disassembly and assembly device, which aims to solve the above-mentioned problems.

[0059] Please refer to the following: Figures 1-6 A diesel engine gear pump disassembly and assembly device includes a fixing part 1, an adjusting part 2, and a supporting part 3. The fixing part 1 is used to connect to a diesel engine 5. The adjusting part 2 is movably connected to the fixing part 1. The supporting part 3 is located at the end of the adjusting part 2 away from the fixing part 1 and is connected to the adjusting part 2. The supporting part 3 includes a first support frame 31, a second support frame 32, and a crossbeam 33. The second support frame 32 is spaced apart from the first support frame 31. The first support frame 31 and the second support frame 32 cooperate to support the gear pump 6 in the direction from the supporting part 3 toward the fixing part 1. The crossbeam 33 is located on the side of the first support frame 31 and the second support frame 32 facing the fixing part 1 and is connected to the first support frame 31 and the second support frame 32 respectively. A portion of the adjusting part 2 is located on the side of the crossbeam 33 facing the fixing part 1 and is movably connected to the crossbeam 33.

[0060] This application uses a fixing part 1 to connect to a corresponding position on the diesel engine 5 to support the entire disassembly and assembly device to the disassembly and assembly position of the gear pump 6. An adjusting part 2 is used to adjust the specific position of the supporting part 3 along the height direction, so that the supporting part 3 can smoothly reach the predetermined position and support the gear pump 6. The supporting part 3 supports the gear pump 6, and simultaneously uses a first support frame 31 and a second support frame 32 to support both sides of the flange of the gear pump 6, ensuring that the gear pump 6 is correctly positioned, thereby facilitating the disassembly and assembly of the gear pump 6. This disassembly and assembly device can effectively improve the efficiency and quality of disassembly and assembly of the gear pump 6, while also ensuring the safety of the disassembly and assembly personnel. Furthermore, the disassembly and assembly device can achieve rapid replacement of the engine-driven gear pump 6 under diesel engine test bench and actual ship application conditions.

[0061] Specifically, in this embodiment, the disassembly and assembly device is used to connect to the body of the diesel engine 5 and to support the gear pump 6, thereby enabling quick disassembly and assembly of the gear pump 6. The diesel engine 5 body has numerous bolt holes above the mounting surface of the gear pump 6, which are used to fix the fixing part 1. Specifically, the fixing part 1 has a fourth through hole 111. Bolts pass through the fourth through hole 111 and are locked into the fixing bolt holes on the diesel engine 5 body, thereby fixing the fixing part 1 and connecting the gear pump disassembly and assembly device to the diesel engine 5 body. The adjusting part 2 is movably connected to the fixing part 1, allowing the adjusting part 2 to move along its length. This allows the supporting part 3 to move along the length of the adjusting part 2, thereby adjusting the relative distance between the fixing part 1 and the supporting part 3, thus enabling the supporting part 3 to support the gear pump 6.

[0062] It should be noted that when fixing the disassembly and assembly device, the specific fixing position needs to take into account the position of the flange at the horizontal position of the gear pump 6. At this time, the flange needs to correspond to the position of the support part 3 to ensure that the support part 3 can support the flange to achieve the disassembly and assembly of the gear pump 6. Since the structure of the relevant components of different diesel engines 5 is different, and the model of gear pump 6 is different, the adjustment part 2 is set to allow the support part 3 to move and adjust along the direction of the arrangement of the support part 3 and the fixing part 1, thereby achieving the support part 3 supporting the gear pump 6.

[0063] It should also be noted that the support part 3 of this application embodiment supports the gear pump 6 mainly by providing vertical support for the horizontally placed flange of the gear pump 6. This enables the gear pump 6 to be stably supported, thereby facilitating the docking and installation of the gear pump 6 with the diesel engine 5 body and effectively saving manpower and material resources.

[0064] In addition, in this embodiment, the first support frame 31 and the second support frame 32 of the support part 3 are connected and fixed by a crossbeam 33 to form a whole, and the first support frame 31 and the second support frame 32 are arranged at intervals relative to each other. At this time, the first support frame 31 and the second support frame 32 support the flange of the gear pump 6 from both sides of the gear pump 6, thus ensuring the stability of the gear pump 6 support. At the same time, the adjusting part 2 is fixed to the crossbeam 33, thereby using the crossbeam 33 and the adjusting part 2 to support the first support frame 31 and the second support frame 32, thus facilitating the hoisting and disassembly of the gear pump 6.

[0065] In this embodiment, the support part 3 can be an integrally formed structure, which can further improve the connection strength between the crossbeam 33 and the first support frame 31 and the second support frame 32, thereby further ensuring the stability of the overall structure of the support part 3 when hoisting and supporting the gear pump 6, and thus improving the operational safety of disassembling and assembling the gear pump 6.

[0066] It should be noted that, in this embodiment of the application, part of the adjusting part 2 is disposed on the side of the crossbeam 33 facing the fixing part 1 and is movably connected to the crossbeam 33. At this time, the end of the adjusting part 2 near the crossbeam 33 can be rotatably connected to the crossbeam 33, which makes it easy for the fixing part 1 and the adjusting part 2 to adjust the connection position.

[0067] In some embodiments, the first support frame 31 includes a first support platform 311 and a first extension plate 312. The first support platform 311 is used to support the gear pump 6 in the direction from the support portion 3 toward the fixing portion 1. The first extension plate 312 is disposed on the side of the first support platform 311 facing the crossbeam 33 and is connected to the first support platform 311. The side of the first extension plate 312 away from the first support platform 311 is connected to the crossbeam 33. At least a portion of the first support platform 311 is located on the side of the first extension plate 312 facing the second support frame 32. The second support frame 32 includes a second support platform 321 and a second extension plate 322. The second support platform 321 is arranged opposite to the first support platform 311 along the direction in which the first support frame 31 and the second support frame 32 are arranged, and is used to support the gear pump 6 in the direction from the support part 3 toward the fixing part 1. The second extension plate 322 is disposed on the side of the second support platform 321 facing the crossbeam 33 and is connected to the second support platform 321. The side of the second extension plate 322 away from the second support platform 321 is connected to the crossbeam 33, and at least a portion of the second support platform 321 is located on the side of the second extension plate 322 facing the first support frame 31.

[0068] In this embodiment, the first support platform 311 and the second support platform 321 are used to abut against and support the flange of the gear pump 6 inlet. The first extension plate 312 and the second extension plate 322 are used to extend along the support part 3 toward the fixing part 1 and connect with the crossbeam 33, thereby avoiding interference from the crossbeam 33 when the first support platform 311 and the second support platform 321 support the flange of the gear pump 6.

[0069] It should be noted that, in this embodiment of the application, by setting the first extension plate 312 and the second extension plate 322, on the one hand, it serves as a reinforcing rib, effectively preventing the deformation of the first support platform 311 and the second support platform 321 due to the excessive weight of the gear pump 6.

[0070] Furthermore, in this embodiment, the first extension plate 312 and the second extension plate 322, together with the first support platform 311, the second support platform 321, and the crossbeam 33, form a accommodating space. This allows the gear pump 6 to slide along the first support platform 311 and the second support platform 321 within this accommodating space after removal or before installation, facilitating subsequent hoisting, removal, or docking installation of the gear pump 6. Simultaneously, the first extension plate 312 and the second extension plate 322 limit the position of the gear pump 6 along the arrangement direction of the first support frame 31 and the second support frame 32, preventing the gear pump 6 from shifting its position between the first support frame 31 and the second support frame 32. This ensures the stability of the disassembly and assembly device support and prevents reduced service life of the disassembly and assembly device and damage to the diesel engine 5's structure due to uneven stress.

[0071] In some embodiments, the first support frame 31 further includes a first limiting plate 313, which is disposed on one side of the first support platform 311 along the length direction of the first support platform 311, and is connected to the first support platform 311 and the first extension plate 312 respectively; the second support frame 32 further includes a second limiting plate 323, which is disposed on one side of the second support platform 321 along the length direction of the second support platform 321, and is connected to the second support platform 321 and the second extension plate 322 respectively; the first limiting plate 313 and the second limiting plate 323 are arranged opposite to each other along the arrangement direction of the first support frame 31 and the second support frame 32.

[0072] In this embodiment, the first limiting plate 313 and the second limiting plate 323 can block the flange of the gear pump 6 when the gear pump 6 slides along the length direction of the first support platform 311 and the second support platform 321 toward the engine body away from the diesel engine 5, thereby limiting the movement position of the gear pump 6 and preventing the gear pump 6 from sliding out of the support part 3 due to inertia and causing safety hazards.

[0073] It is understandable that, along the arrangement direction of the first support frame 31 and the second support frame 32, the first limiting plate 313 and the second limiting plate 323 are arranged opposite to each other. At this time, the positions of the first limiting plate 313 and the second limiting plate 323 are the same, which can simultaneously block and limit the flange of the gear pump 6, thereby avoiding the reduction in service life caused by only one of the first limiting plate 313 and the second limiting plate 323 playing a limiting role.

[0074] In some embodiments, the first support frame 31 further includes a first reinforcing plate 314, which is connected to the side of the first extension plate 312 away from the first support platform 311. The first reinforcing plate 314 and the first support platform 311 are spaced apart along the direction of the support portion 3 toward the fixing portion 1, and a crossbeam 33 is connected to the side of the first reinforcing plate 314 away from the first extension plate 312. The second support frame 32 further includes a second reinforcing plate 324, which is connected to the side of the second extension plate 322 away from the second support platform 321. The second reinforcing plate 324 and the second support platform 321 are spaced apart along the direction of the support portion 3 toward the fixing portion 1, and a crossbeam 33 is connected to the side of the second reinforcing plate 324 away from the second extension plate 322.

[0075] In this embodiment, the arrangement of the first reinforcing plate 314 and the second reinforcing plate 324 allows the first support platform 311, the first extension plate 312, and the first reinforcing plate 314 to form a C-shaped channel steel, and the second support platform 321, the second extension plate 322, and the second reinforcing plate 324 to form another C-shaped channel steel. The two C-shaped channel steels are connected by a crossbeam 33 for hoisting the gear pump 6. The first reinforcing plate 314 and the second reinforcing plate 324 also serve to strengthen the structure and improve the overall bending effect of the support part 3. In addition, the first reinforcing plate 314 and the second reinforcing plate 324 are both coplanar with the crossbeam 33 and connected to the crossbeam 33 along the extension direction of the crossbeam 33. The crossbeam 33 is then connected to the first extension plate 312 via the first reinforcing plate 314, and to the second extension plate 322 via the second reinforcing plate 324, increasing the connection area and thus improving the connection strength.

[0076] It is understandable that the crossbeam 33 can be integrally connected with the first reinforcing plate 314 and the second reinforcing plate 324, which can further ensure the connection strength and structural stability.

[0077] In some embodiments, along the length of the first support platform 311, the first reinforcing plate 314 and the first limiting plate 313 are spaced apart, and the first extension plate 312, the first limiting plate 313 and the first reinforcing plate 314 form a first clearance groove 315; along the length of the second support platform 321, the second reinforcing plate 324 and the second limiting plate 323 are spaced apart, and the second extension plate 322, the second limiting plate 323 and the second reinforcing plate 324 form a second clearance groove 325; along the arrangement direction of the first support frame 31 and the second support frame 32, the first clearance groove 315 and the second clearance groove 325 are arranged opposite to each other.

[0078] In this embodiment, the first clearance groove 315 and the second clearance groove 325 are used to provide clearance space for the gear pump 6 to move away from the support part 3 or to enter the accommodating space of the support part 3, thus facilitating the installation and removal of the gear pump 6.

[0079] It should be noted that when the gear pump 6 is disassembled or assembled, the first clearance groove 315 and the second clearance groove 325 are located at the end of the support 3 away from the diesel engine 5. This provides operating space for the gear pump 6 to detach from the support 3 or be hoisted into the accommodating space of the support 3. Specifically, the length of the first clearance groove 315 and the second clearance groove 325 is greater than the outer diameter of the flange of the gear pump 6. This facilitates the smooth passage of the flange through the first clearance groove 315 and the second clearance groove 325 when the gear pump 6 is hoisted for disassembly or assembly.

[0080] In some embodiments, along the length of the first support platform 311 and the second support platform 321, the size of the first reinforcing plate 314 is larger than the size of the crossbeam 33, and the size of the second reinforcing plate 324 is larger than the size of the crossbeam 33.

[0081] In this embodiment, the arrangement of the first reinforcing plate 314 and the second reinforcing plate 324 allows the bent connection between the crossbeam 33 and the legs of the first extension plate 312 and the second extension plate 322 to be transformed into a horizontal connection between the first reinforcing plate 314 and the second reinforcing plate 324 and the crossbeam 33. Furthermore, the first reinforcing plate 314 and the second reinforcing plate 324 and the crossbeam 33 can be integrally formed, which can increase the connection strength between the first reinforcing plate 314 and the second reinforcing plate 324 and the crossbeam 33. Simultaneously, the first reinforcing plate... The reinforcing plate 314 is bent and connected to the first extension plate 312, and the second reinforcing plate 324 is bent and connected to the second extension plate 322. Since the dimensions of the first reinforcing plate 314 and the second reinforcing plate 324 are both larger than the dimensions of the crossbeam 33, the connection area between the first reinforcing part and the first extension plate 312 is larger than the connection area between the crossbeam 33 and the first extension plate 312, and the connection area between the second reinforcing part and the second extension plate 322 is larger than the connection area between the crossbeam 33 and the second extension plate 322. Therefore, the connection strength is also improved.

[0082] Furthermore, in some embodiments, the first support frame 31 and the second support frame 32 are structurally identical, and the first support frame 31 and the second support frame 32 are symmetrically arranged with the center line of the crossbeam 33 along the width direction as the axis of symmetry. In this case, the first support frame 31 and the second support frame 32 can have the same function and achieve the same effect.

[0083] In some embodiments, the first support frame 31 further includes a first slide rail 316, which is disposed on the side of the first support platform 311 facing the crossbeam 33 and is connected to the first support platform 311; the second support frame 32 further includes a second slide rail 326, which is disposed on the side of the second support platform 321 facing the crossbeam 33 and is connected to the second support platform 321; wherein, the first slide rail 316 and the second slide rail 326 are used to allow the gear pump 6 to slide along the length direction of the first support frame 31 and the second support frame 32.

[0084] In this embodiment, by setting a first slide rail 316 on the first support platform 311 and a second slide rail 326 on the second support platform 321, when the flange of the gear pump 6 falls into the accommodating space, the first slide rail 316 and the second slide rail 326 support the flange, and the gear pump 6 can slide by pushing with external force. This can effectively avoid dry friction between the gear pump 6 and the first support platform 311 and the second support platform 321, while ensuring the continuity of pushing, making the disassembly and assembly of the gear pump 6 more time-saving and labor-saving.

[0085] It should be noted that the gear pump disassembly and assembly device in this application embodiment is used to move the gear pump 6 away from the diesel engine 5 or towards the diesel engine 5 from a direction away from the diesel engine 5. Therefore, considering the material cost and the weight of the disassembly and assembly device, it is preferred that the first support frame 31 and the second support frame 32 be straight lines perpendicular to the diesel engine 5. At this time, the gear pump 6 is also pushed along a straight line. Therefore, the first slide rail 316 and the second slide rail 326 are preferably cylindrical slide rails. At this time, the gear pump 6 will shift position due to the direction of the external force, which makes it easier to achieve accurate docking of the gear pump 6 and realize quick installation.

[0086] In some embodiments, the crossbeam 33 has a first through hole 331, which passes through the crossbeam 33 along the arrangement direction of the support part 3 and the adjustment part 2; the adjustment part 2 includes an adjustment rod 21 and a limiting member 22, the adjustment rod 21 is movably inserted through the first through hole 331, and the end of the adjustment rod 21 near the fixing part 1 is movably connected to the fixing part 1; the limiting member 22 is disposed on the side of the crossbeam 33 away from the fixing part 1, and the limiting member 22 is connected to the adjustment rod 21.

[0087] In this embodiment, the first through hole 331 is a smooth hole with no internal threads on its inner wall. The adjusting rod 21 is movably inserted through the first through hole 331, allowing it to move freely within the hole, which facilitates its rotation. The limiting member 22 is used to limit the movement of the adjusting rod 21 along its length and the crossbeam 33. When the adjusting rod 21 is connected to the fixing part 1, the limiting member 22 and the crossbeam 33 mutually limit each other, thus hoisting the support part 3 as a whole, thereby supporting the gear pump 6.

[0088] It should be noted that, since the adjusting rod 21 is movably inserted into the first through hole 331, and the crossbeam 33 abuts against the limiting member 22 when the gear pump 6 is disassembled and assembled, and the adjusting rod 21 is movably connected to the fixed part 1, this application adjusts the distance between the support part 3 and the fixed part 1 by adjusting the fixed connection position of the fixed part 1 and the adjusting rod 21, thereby adjusting the fixed height of the support part 3.

[0089] It should also be noted that the first through hole 331 is located at the center of the crossbeam 33. At this time, the support part 3 is hoisted by the adjusting rod 21, which can ensure that the force on the support part 3 is relatively uniform.

[0090] In some embodiments, the fixing part 1 includes a body 11 and a connector 12. The body 11 is used to connect with the diesel engine 5. The connector 12 is disposed on the side of the body 11 away from the diesel engine 5. The connector 12 has a second through hole 121. The second through hole 121 passes through the connector 12 along the arrangement direction of the support part 3 and the fixing part 1. The adjusting rod 21 is movably inserted through the second through hole 121 and connected to the connector 12.

[0091] In this embodiment, the disassembly and assembly device is connected to the diesel engine 5 via the main body 11, thereby enabling the disassembly and assembly of the gear pump 6. The connecting member 12 is used to connect with the adjusting rod 21 to fix the adjusting part 2 and the supporting part 3 to the fixing part 1.

[0092] It should be noted that in this embodiment, the second through hole 121 is used for the adjusting rod 21 to pass through. In this case, the second through hole 121 can be a smooth hole or a threaded hole. An external thread is provided on the outside of the adjusting rod 21. When the second through hole 121 is a smooth hole, a nut can be provided at the end of the adjusting rod 21. The nut is threadedly connected to the adjusting rod 21, and the nut and the connecting piece 12 mutually limit each other to realize the hoisting of the adjusting part 2 and the supporting part 3.

[0093] Of course, in some embodiments, the adjusting rod 21 is threadedly connected to the connecting member 12. Since the adjusting rod 21 is movably inserted into the first through hole 331, and the adjusting rod 21 is not connected to the crossbeam 33, the size of the adjusting rod 21 between the connecting member 12 and the crossbeam 33 can be adjusted by directly rotating the adjusting rod 21, thereby adjusting the support position of the support part 3.

[0094] Furthermore, the adjustment unit 2 also includes a first adjustment terminal 26, which is disposed at the end of the adjustment rod 21 away from the limiting member 22 and is connected to the adjustment rod 21. The first adjustment terminal 26 provides an adjustment fulcrum for adjusting the size of the adjustment rod 21 between the connecting member 12 and the crossbeam 33, facilitating adjustment operations by the operator.

[0095] Specifically, the first adjustment terminal 26 can be a hexagonal connector. The first adjustment terminal 26 can be clamped and rotated with the help of a hexagonal wrench or an adjustable wrench, thereby rotating the adjustment rod 21 and adjusting the size of the adjustment rod 21 between the connector 12 and the crossbeam 33, so that the support part 3 reaches the expected support position.

[0096] In some embodiments, the fixing part 1 further includes a positioning member 13 and an extension rod 14. The positioning member 13 is spaced apart from the connecting member 12 along the arrangement direction of the first support frame 31 and the second support frame 32. The extension rod 14 is disposed between the positioning member 13 and the connecting member 12 along the arrangement direction of the first support frame 31 and the second support frame 32, and is connected to both the positioning member 13 and the connecting member 12. The adjusting part 2 further includes a positioning rod 23. One end of the positioning rod 23 is connected to the crossbeam 33, and the end of the positioning rod 23 away from the crossbeam 33 is movably connected to the positioning member 13.

[0097] In this embodiment, the positioning member 13 and the connecting member 12 are connected by the extension rod 14, which provides two fixed connection points for the fixing part 1. The adjusting rod 21 is connected to the connecting member 12, and the positioning rod 23 is connected to the positioning member 13, forming a more stable positioning and fixing structure, which further ensures the stability of the fixing part 1 in hoisting the support part 3.

[0098] In some embodiments, the positioning member 13 has a third through hole 131, which extends through the positioning member 13 along the arrangement direction of the support part 3 and the fixing part 1, and the positioning rod 23 is movably inserted through the third through hole 131; the adjusting part 2 also includes a positioning nut 24, which is disposed on the side of the positioning member 13 away from the crossbeam 33, and the positioning nut 24 is threadedly connected to the positioning rod 23.

[0099] In this embodiment, the third through hole 131 is a smooth hole, and the positioning rod 23 is movably inserted into the third through hole 131. The positioning rod 23 is fixedly connected to the crossbeam 33, which can be a welded connection. In this case, the positioning nut 24 is threadedly connected to the positioning rod 23, which can further stabilize the connection between the fixing part 1, the adjusting part 2 and the supporting part 3.

[0100] It should be noted that in this embodiment, the adjusting rod 21 is movably inserted into the first through hole 331, and the positioning rod 23 is movably inserted into the third through hole 131. Therefore, when the support part 3 pushes the fixing part 1 upward, the adjusting rod 21 can gradually pass through the first through hole 331 to the side away from the fixing part 1, and the positioning rod 23 can gradually pass through the positioning part 13 to the side away from the crossbeam 33. Therefore, the fixing part 1 and the support part 3 have high flexibility and it is easier to adjust the relative position of the adjusting rod 21 and the connecting part 12 by selecting the adjusting rod 21 clockwise or counterclockwise. When the size of the adjusting rod 21 between the connecting member 12 and the limiting member 22 decreases, the adjusting rod 21 drives the limiting member 22 to move. The limiting member 22 then drives the crossbeam 33 and the positioning rod 23 to move towards the connecting member 12. This facilitates the adjustment of the support part 3 towards the fixed part 1. Further tightening the positioning nut 24 allows the positioning nut 24 to abut against the positioning member 13, dispersing the gravity of the support part 3 and the gear pump 6, reducing localized stress, and thus improving service life. When the size of the adjusting rod 21 between the connecting member 12 and the limiting member 22 needs to be increased, first loosen the positioning nut 24, then rotate the adjusting rod 21 to increase its size between the connecting member 12 and the limiting member 22 until the support part 3 reaches the predetermined position. Then stop rotating the adjusting rod 21 and tighten the positioning nut 24.

[0101] In some embodiments, the fixing part 1 further includes two positioning members 13 and two extension rods 14. Along the arrangement direction of the first support frame 31 and the second support frame 32, the two positioning members 13 are spaced apart on both sides of the connector 12, and each extension rod 14 is disposed between a positioning member 13 and a connector 12, and the extension rod 14 is connected to the positioning member 13 and the connector 12 on both sides respectively; the adjusting part 2 further includes two positioning rods 23. Along the arrangement direction of the first support frame 31 and the second support frame 32, the two positioning rods 23 are spaced apart on both sides of the adjusting rod 21, and each positioning rod 23 is movably connected to a positioning member 13.

[0102] In this embodiment, with the central axis of the adjusting rod 21 as the center, there are even two extension rods 14, two positioning parts 13 and two positioning rods 23 symmetrically arranged. This enables the adjusting part 2 to apply force evenly to the support part 3, ensuring that the support part 3 is subjected to uniform force at all points. The connection between the support part 3 and the adjusting part 2 is more stable, which can prevent the gear pump 6 from shifting position when supported by the support part 3, thus avoiding the gear pump 6 from tilting.

[0103] In some embodiments, the body 11 has a fourth through hole 111, which extends through the body 11 along the length direction of the first support frame 31; the fourth through hole 111 extends along the arrangement direction of the first support frame 31 and the second support frame 32.

[0104] In this embodiment, by providing a fourth through hole 111 on the main body 11, it is convenient to fix the main body 11 to the engine block of the diesel engine 5 using bolts, thereby facilitating the fixation of the entire disassembly and assembly device. The fourth through hole 111 can be an oblong hole (slender hole) or a rectangular hole, so that the fixing position of the main body 11 can be adjusted according to the arrangement direction of the first support frame 31 and the second support frame 32 as needed, thereby achieving effective positioning and support for the gear pump 6 and facilitating the disassembly and assembly of the gear pump 6.

[0105] In some embodiments, the adjusting part 2 further includes a thrust bearing 25, which is disposed between the crossbeam 33 and the limiting member 22, and the adjusting rod 21 is movably inserted into the thrust bearing 25.

[0106] In this embodiment, the thrust bearing 25 is positioned between the crossbeam 33 and the limiting member 22 to overcome the friction between the limiting member 22 and the crossbeam 33, ensuring that the adjusting rod 21 can rotate smoothly to adjust the support position of the support part 3. After the fixing part 1 is fixed to the body of the diesel engine 5, there may be a situation where it is necessary to rotate the adjusting rod 21 to adjust the support position of the support part 3. At this time, one side of the thrust bearing 25 abuts against the limiting member 22, and the side of the thrust bearing 25 away from the limiting member 22 abuts against the crossbeam 33, which can withstand axial force. When the adjusting rod 21 is rotated, the side of the thrust bearing 25 that contacts the crossbeam 33 does not rotate. This allows the adjusting rod 21 to rotate smoothly with less friction, while avoiding frictional damage between the crossbeam 33 and the limiting member 22.

[0107] Furthermore, the thrust bearing 25 in this embodiment can be a thrust ball bearing.

[0108] In some embodiments, at least two guide rods 4 are also included, which are used to connect to the diesel engine 5 to guide and position the installation of the gear pump 6.

[0109] In this embodiment, at least two guide rods 4 are provided. Before the gear pump 6 is installed, they are first installed in the bolt holes of the gear pump 6 corresponding to the diesel engine 5. At this time, when the gear pump 6 moves toward the body of the diesel engine 5, the guide rods 4 are spaced between the gear pump 6 and the body of the diesel engine 5, which effectively avoids structural damage caused by collision between the gear pump 6 and the body of the diesel engine 5 or other components. At the same time, the guide rods 4 are connected to the corresponding bolt holes on the gear pump 6, which can play a good guiding role and facilitate the rapid installation of the gear pump 6.

[0110] It should be noted that the end of the guide rod 4 away from the diesel engine 5 is provided with a second adjustment terminal 41. The second adjustment terminal 41 can be a hexagonal connector, which is connected to the guide rod 4 to provide a force point for the installation and removal of the guide rod 4, so as to facilitate the connection between the guide rod 4 and the diesel engine 5. After the gear pump 6 is connected to the diesel engine 5, the guide rod 4 can be removed to release the corresponding bolt holes, ensuring that all bolt holes can be locked and fixed.

[0111] It should also be noted that the maximum outer diameter of the second adjusting terminal 41 is smaller than the maximum outer diameter of the guide rod 4, and the outer diameter of the end of the guide rod 4 near the second adjusting terminal 41 gradually decreases to the maximum outer diameter of the second adjusting terminal 41, so that the guide rod 4 can be smoothly inserted into the bolt hole on the gear pump 6 to achieve the guiding function.

[0112] In practical application, the diesel engine gear pump disassembly and assembly device of this embodiment first removes the flanges at the inlet and outlet of the gear pump 6, and then supports the gear pump 6 with the first support frame 31 and the second support frame 32 of the support part 3. Specifically, the main body of the gear pump 6 is positioned between the first support frame 31 and the second support frame 32, the flange at the inlet end of the gear pump 6 is positioned between the first support platform 311 and the first reinforcing plate 314, and between the second support platform 321 and the second reinforcing plate 324. Then, the fixing part 1 is fixed to the body of the diesel engine 5 using the corresponding bolt holes, and the adjusting part 2 is adjusted so that the first support platform 311 and the second support platform 321 abut against the flange of the gear pump 6. At this time, the bolts connecting the gear pump 6 to the body of the diesel engine 5 are removed, allowing the gear pump 6 to detach from the body of the diesel engine 5 and move freely. By pushing the gear pump 6, the gear pump 6 is moved to the first clearance groove 315 and the second clearance groove 325. The gear pump 6 is fixed with slings, and the gear pump 6 is lifted away with the help of a crane, thus realizing the disassembly of the gear pump 6. When it is necessary to install the gear pump 6, first install the guide rod 4 in the corresponding mounting bolt hole of the gear pump 6, with part of it protruding from the outside of the diesel engine 5 body. Use a crane to lift the gear pump 6 between the first support frame 31 and the second support frame 32, and make the flange on the gear pump 6 reach the first slide rail 316 and the second slide rail 326 through the first clearance groove 315 and the second clearance groove 325. Manually push the gear pump 6 to the gear pump installation position, use the guide rod 4 to push the gear pump 6 into place, and finally fix the gear pump 6 to the diesel engine 5 body with fixing bolts. Remove the guide rod 4, and continue to tighten the fixing bolts into the bolt holes connected to the guide rod 4. Fix the inlet and outlet bolts of the gear pump 6 to complete the installation of the gear pump 6.
