DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0056] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined. In the description of this application, "vertical" means completely vertical at 90° or almost completely vertical, for example, an angle within the range of 80° to 100° is considered vertical. Similarly, "parallel" means completely parallel or almost completely parallel, for example, an angle within 10° of completely parallel is considered parallel.

[0057] As an important component of the diesel engine, the diesel engine gear pump has the following functions: to provide the diesel engine with sufficient and appropriate amount of coolant or lubricating oil to ensure that the diesel engine works in a relatively efficient temperature range. The performance of its load directly affects the operation and reliability of the diesel engine. Different gear pump schemes will be used to verify its impact on the performance of the diesel engine during the whole machine test, so the gear pump needs to be disassembled and assembled frequently. At the same time, under the conditions of actual ship application, the gear pump also needs to be disassembled and assembled for diesel engine maintenance and other situations. The gear pump is connected to the peripheral cooling pipe and lubricating oil pipe, and the gear pump also needs to be connected to the diesel engine or diesel engine components. Other components such as the lubricating oil module, the thermostatic valve box, the oil-water distribution box and the lubricating oil cooler will be installed directly above the gear pump. The current disassembly and assembly method is to disengage the inlet and outlet connection bolts of the gear pump, fix the water outlet of the gear pump with a sling, disassemble the fixing bolts of the gear pump and the diesel engine body, disengage the stopper of the gear pump and the diesel engine body by manpower, and use a crane to lift the gear pump away. Due to the irregular shape of the gear pump, the gear pump cannot be lifted normally, and there are certain safety hazards during the disassembly process. During reassembly, it cannot be installed by hoisting, and can only be installed by crane. If the hoisting method is used for disassembly and assembly, the components directly above the gear pump must be completely removed, which will inevitably increase labor costs and replacement costs of wearing parts. Once the gear pump slips, there will be safety risks for the assemblers, low assembly efficiency and uncontrollable quality.

[0058] In view of this, an embodiment of the present application provides a diesel engine gear pump disassembly and assembly device, aiming to solve the above-mentioned problems.

[0059] Please refer to Figure 1-Figure 6 A diesel engine gear pump disassembly and assembly device comprises a fixing part 1, an adjusting part 2 and a supporting part 3, wherein the fixing part 1 is used to be connected to a diesel engine 5, the adjusting part 2 is movably connected to the fixing part 1, and the supporting part 3 is arranged at one end of the adjusting part 2 away from the fixing part 1 and is connected to the adjusting part 2; the supporting part 3 comprises a first supporting frame 31, a second supporting frame 32 and a crossbeam 33, the second supporting frame 32 is arranged at intervals from the first supporting frame 31, and the first supporting frame 31 and the second supporting frame 32 cooperate to support the gear pump 6 along the direction of the supporting part 3 toward the fixing part 1; the crossbeam 33 is arranged on the side of the first supporting frame 31 and the second supporting frame 32 toward the fixing part 1, and is respectively connected to the first supporting frame 31 and the second supporting frame 32; a part of the adjusting part 2 is arranged on the side of the crossbeam 33 toward the fixing part 1, and is movably connected to the crossbeam 33.

[0060] The present application is connected to the corresponding position on the diesel engine 5 through the fixing part 1 to support the entire disassembly and assembly device to the disassembly and assembly position of the gear pump 6. The 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 is used to support the gear pump 6, and at the same time, the first supporting frame 31 and the second supporting frame 32 are used to support the two sides of the flange of the gear pump 6, so that the gear pump 6 is guaranteed to be in the facing position, thereby facilitating the disassembly and assembly of the gear pump 6. The disassembly and assembly device of the present application can not only effectively improve the disassembly and assembly efficiency and quality of the gear pump 6, but also ensure the safety of the disassembly and assembly workers. At the same time, the disassembly and assembly device can realize the rapid replacement of the engine-belt gear pump 6 under the conditions of the diesel engine test bench and actual ship application.

[0061] Specifically, in the embodiment of the present application, the disassembly and assembly device is used to connect with the body of the diesel engine 5, and is used to support the gear pump 6, so as to realize the rapid disassembly and assembly of the gear pump 6. Among them, there will be many bolt holes on the body of the diesel engine 5 corresponding to the upper part of the mounting stop of the gear pump 6, and these bolt holes can be used to fix the fixing part 1. Specifically, the fixing part 1 is provided with a fourth through hole 111, and a bolt is passed through the fourth through hole 111, and is locked in the fixed bolt hole on the body of the diesel engine 5, so as to realize the fixation of the fixing part 1, and then realize the connection between the gear pump disassembly and assembly device and the body of the diesel engine 5. The adjusting part 2 is movably connected with the fixing part 1, so that the adjusting part 2 can be moved along its length direction, so that the supporting part 3 can be moved along the length direction of the adjusting part 2, so as to realize the adjustment of the relative distance between the fixing part 1 and the supporting part 3, so as to realize the support of the gear pump 6 by the supporting part 3.

[0062] It should be noted that when the disassembly and assembly device is fixed, the specific fixing position needs to consider the position of the flange of 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 realize the disassembly and assembly of the gear pump 6. Since the structures of the relevant components corresponding to different types of diesel engines 5 are different, the models of the gear pump 6 are different. Therefore, by setting the adjustment part 2, the support part 3 can be moved and adjusted along the direction in which the support part 3 and the fixing part 1 are arranged, so that the support part 3 supports the gear pump 6.

[0063] It should also be noted that the support of the gear pump 6 by the support part 3 of the embodiment of the present application is mainly to vertically support the horizontally placed flange of the gear pump 6, so that the gear pump 6 can be stably supported, thereby facilitating the docking and installation of the gear pump 6 and the body of the diesel engine 5, effectively saving manpower and material resources.

[0064] In addition, in the embodiment of the present application, the first support frame 31 and the second support frame 32 of the support part 3 are connected and fixed by the cross beam 33 to form a whole, and the first support frame 31 and the second support frame 32 are arranged relatively spaced apart. At this time, the first support frame 31 and the second support frame 32 are used to support the flange of the gear pump 6 from both sides of the gear pump 6, thereby ensuring the stability of the support of the gear pump 6. At the same time, the adjustment part 2 is connected to the cross beam 33, so that the first support frame 31 and the second support frame 32 are supported by the cross beam 33 and the adjustment part 2, so that the lifting and disassembly of the gear pump 6 is convenient.

[0065] In the embodiment of the present application, 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 the gear pump 6, thereby improving the operational safety during disassembly and assembly of the gear pump 6.

[0066] It should be noted that in the embodiment of the present application, part of the adjusting portion 2 is arranged on the side of the beam 33 facing the fixed portion 1 and is movably connected to the beam 33. At this time, the end of the adjusting portion 2 close to the beam 33 can be rotatably connected to the beam 33, so that it is convenient to adjust the connection position of the fixed portion 1 and the adjusting portion 2.

[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 along the direction of the support portion 3 toward the fixed portion 1; the first extension plate 312 is arranged on the side of the first support platform 311 facing the beam 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 beam 33, and at least part 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 along the direction of the support portion 3 toward the fixing portion 1; the second extension plate 322 is arranged on the side of the second support platform 321 facing the beam 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 beam 33, and at least part 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 the embodiment of the present application, the first support platform 311 and the second support platform 321 are used to abut against and support the flange of the inlet of the gear pump 6. The first extension plate 312 and the second extension plate 322 are used to extend along the support portion 3 toward the fixing portion 1 and are connected to the crossbeam 33, so as to avoid interference caused by 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 the embodiment of the present application provides the first extension plate 312 and the second extension plate 322 , which, on the one hand, play the role of reinforcing ribs and effectively prevent the deformation of the first support platform 311 and the second support platform 321 caused by the excessive weight of the gear pump 6 .

[0070] Furthermore, in the embodiment of the present application, the first extension plate 312 and the second extension plate 322 can be arranged to enclose a containing space together with the first support platform 311, the second support platform 321 and the crossbeam 33, so that the gear pump 6 can slide along the first support platform 311 and the second support platform 321 in the containing space after removal or before installation, thereby facilitating the subsequent lifting and evacuation or docking installation of the gear pump 6. At the same time, the first extension plate 312 and the second extension plate 322 can be used to limit the position of the gear pump 6 along the arrangement direction of the first support frame 31 and the second support frame 32, thereby avoiding the position shift of the gear pump 6 between the first support frame 31 and the second support frame 32, thereby ensuring the stability of the support of the disassembly and assembly device, and avoiding the reduction of the service life of the disassembly and assembly device and the damage to the body structure of the diesel engine 5 due to uneven force.

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

[0072] In the embodiment of the present application, the setting of the first limit plate 313 and the second limit 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 direction away from the body of the diesel engine 5, thereby limiting the moving position of the gear pump 6 and preventing the gear pump 6 from sliding out of the support part 3 under the action of inertia and causing a safety hazard.

[0073] It can be understood that along the arrangement direction of the first support frame 31 and the second support frame 32, the first limit plate 313 and the second limit plate 323 are relatively arranged. At this time, the positions of the first limit plate 313 and the second limit plate 323 are the same, which can play a role in blocking and limiting the flange of the gear pump 6 at the same time, thereby avoiding the reduction in service life caused by only one of the first limit plate 313 and the second limit plate 323 playing a limiting role.

[0074] In some embodiments, the first support frame 31 also 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, and the first reinforcing plate 314 and the first support platform 311 are spaced apart along the direction of the support portion 3 toward the fixed portion 1, and the cross beam 33 is connected to the side of the first reinforcing plate 314 away from the first extension plate 312; the second support frame 32 also 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, and the second reinforcing plate 324 and the second support platform 321 are spaced apart along the direction of the support portion 3 toward the fixed portion 1, and the cross beam 33 is connected to the side of the second reinforcing plate 324 away from the second extension plate 322.

[0075] In the embodiment of the present application, the first reinforcing plate 314 and the second reinforcing plate 324 are arranged so that the first support platform 311, the first extension plate 312 and the first reinforcing plate 314 are surrounded by a C-shaped channel steel, and the second support platform 321, the second extension plate 322 and the second reinforcing plate 324 are surrounded by a C-shaped channel steel, and the two C-shaped channel steels are connected by the crossbeam 33 for hoisting the gear pump 6. The first reinforcing plate 314 and the second reinforcing plate 324 also play a role in structural reinforcement, improving the overall bending effect of the support portion 3. In addition, the first reinforcing plate 314 and the second reinforcing plate 324 are both coplanar with the crossbeam 33, and are 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 by means of the first reinforcing plate 314, and the crossbeam 33 is connected to the second extension plate 322 by means of the second reinforcing plate 324, which increases the connection area and thus improves the connection strength.

[0076] It is understandable that the cross beam 33 and the first reinforcement plate 314 and the second reinforcement plate 324 may be connected in one piece, which can further ensure the connection strength and the structural stability.

[0077] In some embodiments, along the length direction 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 avoidance groove 315; along the length direction 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 avoidance groove 325; along the arrangement direction of the first support frame 31 and the second support frame 32, the first avoidance groove 315 and the second avoidance groove 325 are arranged opposite to each other.

[0078] In the embodiment of the present application, the first avoidance groove 315 and the second avoidance groove 325 are used to provide avoidance space for the gear pump 6 to move away from the support portion 3 or for the gear pump 6 to enter the accommodating space of the support portion 3, thereby facilitating the installation and disassembly of the gear pump 6.

[0079] It should be noted that when the gear pump 6 is disassembled, the first avoidance groove 315 and the second avoidance groove 325 are located at one end of the support portion 3 away from the body of the diesel engine 5, which provides operating space for the gear pump 6 to be separated from the support portion 3 or to be hoisted into the accommodating space of the support portion 3. Specifically, the length of the first avoidance groove 315 and the second avoidance groove 325 is greater than the outer diameter of the flange of the gear pump 6, so that when the gear pump 6 is hoisted for disassembly, the flange can pass smoothly through the first avoidance groove 315 and the second avoidance groove 325.

[0080] In some embodiments, along the length direction 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 beam 33 , and the size of the second reinforcing plate 324 is larger than the size of the beam 33 .

[0081] In the embodiment of the present application, the arrangement of the first reinforcing plate 314 and the second reinforcing plate 324 can transform the connection between the cross beam 33 and the first extension plate 312 and the second extension plate 322 into a horizontal plane connection between the first reinforcing plate 314 and the second reinforcing plate 324 and the cross beam 33. Furthermore, the first reinforcing plate 314 and the second reinforcing plate 324 and the cross beam 33 can be integrally formed. In this case, the connection strength between the first reinforcing plate 314 and the second reinforcing plate 324 and the cross beam 33 can be higher. At the same time, the first reinforcing plate 314 and the second reinforcing plate 324 can be integrally formed with the cross beam 33. The strong plate 314 is bent relative to and connected to the first extension plate 312, and the second reinforcing plate 324 is bent relative to and connected to the second extension plate 322. Since the sizes of the first reinforcing plate 314 and the second reinforcing plate 324 are both larger than the size of the beam 33, the connection area between the first reinforcing portion and the first extension plate 312 is larger than the connection area between the beam 33 and the first extension plate 312, and the connection area between the second reinforcing portion and the second extension plate 322 is larger than the connection area between the beam 33 and the second extension plate 322, thereby also improving the connection strength.

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

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

[0084] In the embodiment of the present application, a first slide rail 316 is arranged on the first support platform 311, and a second slide rail 326 is arranged on the second support platform 321. At this time, 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 sliding of the gear pump 6 can be achieved by pushing with an external force, which can effectively avoid dry friction between the gear pump 6 and the first support platform 311 and the second support platform 321, and at the same time ensure the continuity of the push, so that the disassembly and assembly of the gear pump 6 is more time-saving and labor-saving.

[0085] It should be noted that the gear pump disassembly and assembly device of the embodiment of the present application only needs to move the gear pump 6 away from the body of the diesel engine 5, or move it from a direction away from the body of the diesel engine 5 to the body of the diesel engine 5. Therefore, considering the material usage 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 are straight lines perpendicular to the body of the diesel engine 5. At this time, the gear pump 6 is also pushed along a straight line, so the first slide rail 316 and the second slide rail 326 are preferably cylindrical slide rails. At this time, the position of the gear pump 6 is offset due to the direction of the external force, which makes it easier to achieve accurate docking of the gear pump 6 and achieve rapid installation.

[0086] In some embodiments, the beam 33 has a first through hole 331, and the first through hole 331 passes through the beam 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 limit member 22, the adjustment rod 21 can be movably inserted into the first through hole 331, and one end of the adjustment rod 21 close to the fixed part 1 is movably connected to the fixed part 1; the limit member 22 is arranged on the side of the beam 33 away from the fixed part 1, and the limit member 22 is connected to the adjustment rod 21.

[0087] In the embodiment of the present application, the first through hole 331 is a light hole, and its inner wall has no internal thread. The adjusting rod 21 is movably arranged in the first through hole 331, so the adjusting rod 21 can move arbitrarily in the first through hole 331, which is convenient for the rotation of the adjusting rod 21. The limiting member 22 is used to limit the position of the adjusting rod 21 with the cross beam 33 along the length direction of the adjusting rod 21. When the adjusting rod 21 is connected to the fixing part 1, the supporting part 3 is hoisted as a whole by limiting the position of the limiting member 22 with the cross beam 33, thereby supporting the gear pump 6.

[0088] It should be noted that, since the adjusting rod 21 is movably arranged in the first through hole 331, and when the gear pump 6 is disassembled and assembled, the cross beam 33 abuts against the limit member 22, and at the same time, the adjusting rod 21 is movably connected to the fixing part 1, the present application adjusts the distance between the supporting part 3 and the fixing part 1 by adjusting the fixed connection position between the fixing part 1 and the adjusting rod 21, thereby adjusting the fixed height of the supporting 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 adjustment rod 21 , which can ensure that the force on each part of the support part 3 is relatively uniform.

[0090] In some embodiments, the fixing part 1 includes a main body 11 and a connecting member 12, the main body 11 is used to connect to the diesel engine 5; the connecting member 12 is arranged on the side of the main body 11 away from the diesel engine 5, the connecting member 12 has a second through hole 121, the second through hole 121 passes through the connecting member 12 along the arrangement direction of the supporting part 3 and the fixing part 1, and the adjusting rod 21 can be movably passed through the second through hole 121 and connected to the connecting member 12.

[0091] In the embodiment of the present application, the disassembly and assembly device is connected to the diesel engine 5 by connecting the body 11 to the diesel engine 5, so that the gear pump 6 can be disassembled and assembled. Among them, the connecting member 12 is used to connect with the adjusting rod 21 to realize the fixing of the fixing part 1 to the adjusting part 2 and the supporting part 3.

[0092] It should be noted that, in the embodiment of the present application, the second through hole 121 is used for the adjustment rod 21 to pass through, and the second through hole 121 can be a plain hole or a threaded hole. An external thread is provided on the outer side of the adjustment rod 21. When the second through hole 121 is a plain hole, a nut can be provided at the end of the adjustment rod 21, and the nut is threadedly connected to the adjustment rod 21, and the nut and the connecting member 12 are mutually limited to realize the hoisting of the adjustment part 2 and the support 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 can be movably inserted into the first through hole 331, the adjusting rod 21 is not connected to the cross beam 33. Therefore, the size of the adjusting rod 21 between the connecting member 12 and the cross beam 33 can be adjusted by directly rotating the adjusting rod 21, thereby adjusting the supporting position of the support part 3.

[0094] Furthermore, the adjusting portion 2 further includes a first adjusting terminal 26, which is disposed at an end of the adjusting rod 21 away from the limiting member 22, and the first adjusting terminal 26 is connected to the adjusting rod 21. The first adjusting terminal 26 is used to provide an adjusting fulcrum for adjusting the size of the adjusting rod 21 between the connecting member 12 and the crossbeam 33, so as to facilitate the operator to perform the adjustment operation.

[0095] Specifically, the first adjustment terminal 26 can be a hexagonal connector, which can be clamped and rotated by a hexagonal wrench or an adjustable wrench, thereby realizing the rotation of the adjustment rod 21, and then adjusting the size of the adjustment rod 21 between the connecting member 12 and the beam 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 arranged in a spaced relationship with 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 arranged 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 the extension rod 14 is respectively connected to 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 cross beam 33, and one end of the positioning rod 23 away from the cross beam 33 is movably connected to the positioning member 13.

[0097] In the embodiment of the present application, the positioning member 13 and the connecting member 12 are connected by an extension rod 14, thereby providing two fixed connection points for the fixing part 1. The adjustment rod 21 is connected to the connecting member 12, and the positioning rod 23 is connected to the positioning member 13, so as to form a more stable positioning and fixing structure, thereby further ensuring the stability of the fixing part 1 in lifting the supporting part 3.

[0098] In some embodiments, the positioning member 13 has a third through hole 131, the third through hole 131 passes through the positioning member 13 along the arrangement direction of the support portion 3 and the fixing portion 1, and the positioning rod 23 is movably arranged in the third through hole 131; the adjustment portion 2 also includes a positioning nut 24, the positioning nut 24 is arranged on the side of the positioning member 13 away from the cross beam 33, and the positioning nut 24 is threadedly connected to the positioning rod 23.

[0099] In the embodiment of the present application, the third through hole 131 is a light hole, and the positioning rod 23 is movably arranged in the third through hole 131. The positioning rod 23 is fixedly connected to the cross beam 33, which can be specifically welded. At this time, the positioning nut 24 is threadedly connected to the positioning rod 23, so that the connection relationship between the fixing part 1, the adjustment part 2 and the supporting part 3 can be further stabilized.

[0100] It should be noted that, in the embodiment of the present application, the adjusting rod 21 is movably arranged in the first through hole 331, and the positioning rod 23 is movably arranged in the third through hole 131. Therefore, when the supporting part 3 is pushed toward the upper fixed part 1, the adjusting rod 21 can gradually pass through the side of the first through hole 331 away from the fixed part 1, and the positioning rod 23 can gradually pass through the side of the positioning member 13 away from the cross beam 33. Therefore, the flexibility of the fixed part 1 and the supporting part 3 is relatively high, and it is more convenient 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 is reduced, the adjusting rod 21 drives the limiting member 22 to move, and the limiting member 22 drives the cross beam 33 and the positioning rod 23 to move toward the connecting member 12. At this time, it is easy to adjust the support part 3 toward the fixed part 1, and further tighten the positioning nut 24 to achieve the abutment of the positioning nut 24 and the positioning member 13, so as to achieve the dispersion of the gravity of the support part 3 and the gear pump 6, reduce the local force, and thus improve the 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, and then rotate the adjusting rod 21 to increase the size of the adjusting rod 21 between the connecting member 12 and the limiting member 22. After the position of the supporting part 3 reaches the predetermined position, stop rotating the adjusting rod 21, and then tighten the positioning nut 24.

[0101] In some embodiments, the fixing part 1 also 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 connecting member 12, each extension rod 14 is disposed between a positioning member 13 and the connecting member 12, and the extension rod 14 is respectively connected to the positioning members 13 and the connecting member 12 on both sides; the adjusting part 2 also 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 the embodiment of the present application, with the central axis of the adjusting rod 21 as the center, the two extension rods 14, the two positioning members 13 and the two positioning rods 23 are symmetrically even. At this time, the adjusting part 2 can achieve balanced force lifting of the supporting part 3, ensuring that the force is evenly applied to all parts of the supporting part 3, and the connection between the supporting part 3 and the adjusting part 2 is more stable, which can avoid the position deviation of the gear pump 6 when it is supported by the supporting part 3, causing the gear pump 6 to be skewed.

[0103] In some embodiments, the body 11 has a fourth through hole 111 , which penetrates 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 the embodiment of the present application, by setting the fourth through hole 111 on the body 11, it is convenient to fix the body 11 on the body of the diesel engine 5 by bolts, so as to facilitate the fixation of the entire disassembly and assembly device. The fourth through hole 111 can be an oblong hole (waist-shaped hole) or a rectangular hole, so that the fixed position of the body 11 can be adjusted along the arrangement direction of the first support frame 31 and the second support frame 32 according to the needs, thereby achieving effective positioning support for the gear pump 6, and facilitating the disassembly and assembly of the gear pump 6.

[0105] In some embodiments, the adjusting portion 2 further includes a thrust bearing 25 , which is disposed between the cross beam 33 and the limiting member 22 , and the adjusting rod 21 is movably disposed in the thrust bearing 25 .

[0106] In the embodiment of the present application, the thrust bearing 25 is used to be spaced between the measuring and the limiting member 22, and is used to overcome the friction between the limiting member 22 and the cross beam 33, so as to ensure that the adjusting rod 21 can rotate smoothly to adjust the supporting position of the supporting part 3. After the fixing part 1 is fixed to the body of the diesel engine 5, there will be a situation where the adjusting rod 21 needs to be rotated to adjust the supporting position of the supporting part 3. At this time, one side of the thrust bearing 25 is abutted against the limiting member 22, and the side of the thrust bearing 25 away from the limiting member 22 is abutted against the cross beam 33, which can withstand the axial force. At this time, the adjusting rod 21 is rotated, and the side of the thrust bearing 25 in contact with the cross beam 33 does not rotate. In this way, the adjusting rod 21 can be smoothly rotated with less friction, and the friction damage between the measuring and the limiting member 22 can be avoided.

[0107] Furthermore, the thrust bearing 25 of the embodiment of the present application may be a thrust ball bearing.

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

[0109] In the embodiment of the present application, at least two guide rods 4 are provided. Before the gear pump 6 is installed, they are first fixed 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, they can be spaced between the gear pump 6 and the body of the diesel engine 5, effectively avoiding collision between the gear pump 6 and the body or other components of the diesel engine 5 and causing structural damage. At the same time, by docking the guide rods 4 with the corresponding bolt holes on the gear pump 6, they can play a good guiding role, thereby facilitating the rapid installation of the gear pump 6.

[0110] It should be noted that a second adjustment terminal 41 is provided at one end of the guide rod 4 away from the body of the diesel engine 5. The second adjustment terminal 41 can be a hexagonal joint, which is connected to the guide rod 4 to provide a force point for the installation and disassembly of the guide rod 4, thereby facilitating the connection between the guide rod 4 and the body of the diesel engine 5. After the gear pump 6 is docked with the body of the diesel engine 5, the guide rod 4 is removed to release the corresponding bolt holes, thereby 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 close to 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 realize the guiding function.

[0112] When the diesel engine gear pump disassembly and assembly device of the embodiment of the present application is used in a specific application, the flanges of the inlet and outlet of the gear pump 6 are first disassembled, and then the first support frame 31 and the second support frame 32 of the support part 3 support the gear pump 6. Specifically, the main body of the gear pump 6 is located between the first support frame 31 and the second support frame 32, and the flange of the inlet end of the gear pump 6 is located 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 by using the corresponding bolt holes, and the first support platform 311 and the second support platform 321 are abutted against the flange of the gear pump 6 by adjusting the adjustment part 2. At this time, the bolts connecting the gear pump 6 to the body of the diesel engine 5 are removed, so that the gear pump 6 is separated from the body of the diesel engine 5 and can move freely. By pushing the gear pump 6, the gear pump 6 is moved to the first avoidance groove 315 and the second avoidance groove 325, the gear pump 6 is fixed by the sling, and the gear pump 6 is lifted off with the help of the driving, so as to realize the disassembly of the gear pump 6. When the gear pump 6 needs to be installed, first install the guide rod 4 in the mounting bolt hole corresponding to the gear pump 6, and partially protrude from the outside of the diesel engine 5 body. Use the 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 pass through the first avoidance groove 315 and the second avoidance groove 325 to reach the first slide rail 316 and the second slide rail 326. Push the gear pump 6 to the gear pump installation position by manpower, use the guide rod 4 to push the gear pump 6 into place, and finally fix the gear pump 6 to the body of the diesel engine 5 with fixing bolts, remove the guide rod 4, and continue to tighten it with fixing bolts into the bolt holes connected to the guide rod 4, and fix the inlet and outlet bolts of the gear pump 6 to achieve the installation of the gear pump 6.
