Description

Technical Field

[0001] This utility model relates to the field of train turbocharger maintenance technology, and in particular to a precision disassembly device for train turbocharger maintenance. Background Technology

[0002] The precision disassembly device for train turbocharger maintenance is a high-precision tool specifically designed for turbocharger maintenance. It enables precise positioning, stable disassembly, and efficient separation of components during the maintenance process, ensuring that the core components of the turbocharger are not damaged during disassembly, while improving maintenance efficiency and safety.

[0003] Existing turbochargers connect components such as the turbocharger housing with bolts. However, due to the lack of auxiliary positioning parts, the ease of disassembling the turbocharger needs to be optimized and improved. Due to different installation environments and connections with different structures, when the turbocharger needs to be disassembled after installation, workers need to choose different disassembly positions. They often have to squat, bend over, or even lie flat to disassemble it, which seriously affects the efficiency of workers.

[0004] An existing patent (publication number: CN221300997U) discloses a supercharger that is easy to disassemble, including a support frame. The top of the support frame is provided with a movable adjustment mechanism, and the right side of the movable adjustment mechanism is provided with an auxiliary disassembly mechanism. During use, the rotation of the threaded rod, in conjunction with the limiting rod, causes the movable block to move, thereby moving the connecting plate, which facilitates the adjustment of the front and rear position of the supercharger body and is convenient for operators. The rotation of the worm gear, in conjunction with the worm wheel column, causes the gear to rotate, thereby moving the gear plate, which facilitates the adjustment of the left and right position of the supercharger body and is convenient for operators to use disassembly tools. The rotation of the rotating column, in conjunction with the connecting block, causes the mounting frame to rotate. The movement of the sliding rod, in conjunction with the spring, causes the locking block to move, which facilitates the adjustment of the supercharger body to different angles. This reduces the workload of operators, increases disassembly efficiency, and reduces interference with other workpieces.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing turbocharger disassembly tools lack flexible size adjustment capabilities, making it difficult to adapt to the disassembly requirements of different turbocharger models. This results in unstable support or poor compatibility during disassembly, increasing operational complexity and the risk of component damage. Furthermore, existing tools have low adjustment efficiency, making it difficult to meet the needs of fast and precise repairs, thus affecting overall repair efficiency.

[0006] To address this, a precision disassembly device for train turbocharger maintenance was proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a precision disassembly device for the maintenance of train turbochargers. This device can solve the problems that most existing turbocharger disassembly tools lack flexible size adjustment functions, making it difficult to adapt to the disassembly requirements of different turbocharger models. This results in unstable support or poor compatibility during the disassembly process, increasing the complexity of operation and the risk of component damage. At the same time, the existing tools have low adjustment efficiency, making it difficult to meet the needs of fast and precise maintenance, thus affecting the overall maintenance efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a precision disassembly device for train turbocharger maintenance, comprising an electric lifting vehicle, an electric telescopic rod fixedly connected to the right side of the electric lifting vehicle, an adjusting frame fixedly connected to the right side of the electric telescopic rod, a bidirectional threaded rod provided on the inner wall of the adjusting frame, a disassembly mechanism threadedly connected to the surface of the bidirectional threaded rod, a turbocharger structure placed on the inner wall of the disassembly mechanism, a counterweight block provided on the left side of the electric lifting vehicle, the disassembly mechanism including a movable block, the inner wall of the movable block threadedly connected to the surface of the bidirectional threaded rod, a fixing frame fixedly connected to the right side of the movable block, and a support block inserted into the inner wall of the fixing frame.

[0009] Preferably, a knob is movably connected to the inner wall of the fixing frame, and the surface of the knob is threadedly connected to the inner wall of the support block.

[0010] Preferably, the inner wall of the fixing frame is provided with a mounting hole for use with the knob, and the inner wall of the support block is provided with a first threaded hole for use with the knob.

[0011] Preferably, the surface of the movable block is slidably connected to the inner wall of the adjusting frame, and the inner wall of the movable block is provided with a second threaded hole for use with a bidirectional threaded rod.

[0012] Preferably, a support plate is fixedly connected to the right side of the electric lifting vehicle, and fixing plates are fixedly connected to the front and rear sides of the support plate.

[0013] Preferably, a fixing block is fixedly connected to the side of the fixing plate away from the support plate, and a fixing ring is fixedly connected to the side of the fixing block away from the fixing plate.

[0014] Preferably, a slide rod is fixedly connected to the left side of the adjusting frame, and the surface of the slide rod is slidably connected to the inner wall of the fixing ring.

[0015] Preferably, the inner wall of the electric lifting vehicle is slidably connected to an auxiliary bracket, and the bottom of the auxiliary bracket is fixedly connected to a support leg.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application sets up a disassembly mechanism, which adopts a design of a two-way threaded rod driving a movable block. Combined with a replaceable support block, it can flexibly adapt to the size requirements of different models of turbocharger structures. At the same time, the setting of the counterweight block optimizes the center of gravity of the electric lifting vehicle, enhances the stability of operation, makes the disassembly process more convenient and efficient, reduces the operation difficulty and labor intensity of maintenance personnel, and meets diverse maintenance needs.

[0018] 2. This application utilizes an electric lifting vehicle, an electric telescopic rod, an adjusting frame, a bidirectional threaded rod, and a disassembly mechanism. During use, the electric lifting vehicle is moved to the disassembly location of the turbocharger structure. The rotation of the bidirectional threaded rod drives the movable block to move in the same or opposite direction within the adjusting frame, quickly adjusting the spacing of the support blocks to match the turbocharger structure dimensions. Subsequently, the electric lifting vehicle is lowered, and the electric telescopic rod pushes the adjusting frame to precisely insert the support blocks into their pre-fixed positions. Finally, the electric lifting vehicle rises, stabilizing the support blocks to support the turbocharger structure. After precise positioning, disassembly can proceed. The entire process achieves rapid positioning and improves disassembly and assembly efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A precision disassembly device for train turbocharger maintenance includes an electric lifting vehicle 1. An electric telescopic rod 3 is fixedly connected to the right side of the electric lifting vehicle 1. An adjusting frame 4 is fixedly connected to the right side of the electric telescopic rod 3. A bidirectional threaded rod 5 is provided on the inner wall of the adjusting frame 4. A disassembly mechanism 2 is threadedly connected to the surface of the bidirectional threaded rod 5. A turbocharger structure 6 is placed on the inner wall of the disassembly mechanism 2. A counterweight block 7 is provided on the left side of the electric lifting vehicle 1. The disassembly mechanism 2 includes a movable block 201. The inner wall of the movable block 201 is threadedly connected to the surface of the bidirectional threaded rod 5. A fixing frame 202 is fixedly connected to the right side of the movable block 201. A support block 203 is inserted into the inner wall of the fixing frame 202.

[0029] In this embodiment: By setting up a disassembly mechanism 2, which adopts a design of driving the movable block 201 with a bidirectional threaded rod 5, combined with a replaceable support block 203, it flexibly adapts to the size requirements of different models of turbocharger structures 6. At the same time, the setting of the counterweight block 7 optimizes the center of gravity of the electric lifting vehicle 1, enhances the operational stability, makes the disassembly process more convenient and efficient, reduces the operational difficulty and labor intensity of maintenance personnel, and meets diverse maintenance needs. By setting up the electric lifting vehicle 1, electric telescopic rod 3, adjusting frame 4, bidirectional threaded rod 5 and disassembly mechanism 2, the electric... The lifting vehicle 1 moves to the disassembly section of the turbocharger structure 6. The rotation of the bidirectional threaded rod 5 drives the movable block 201 to move in the same or opposite direction within the adjusting frame 4, quickly adjusting the spacing of the support blocks 203 to match the size of the turbocharger structure 6. Then, the electric lifting vehicle 1 is lowered, and the electric telescopic rod 3 pushes the adjusting frame 4 to precisely insert the support blocks 203 into the pre-fixed position. Finally, the electric lifting vehicle 1 rises, allowing the support blocks 203 to stably support the turbocharger structure 6. After precise positioning, disassembly can be performed. The entire process achieves rapid positioning and improves disassembly and assembly efficiency.

[0030] Specifically, such as Figure 5 As shown, a knob 8 is movably connected to the inner wall of the fixing frame 202, and the surface of the knob 8 is threadedly connected to the inner wall of the support block 203.

[0031] Specifically, such as Figure 5As shown, the inner wall of the fixing bracket 202 is provided with a mounting hole 9 for use with the knob 8, and the inner wall of the support block 203 is provided with a first threaded hole 10 for use with the knob 8.

[0032] Specifically, such as Figure 5 As shown, the surface of the movable block 201 is slidably connected to the inner wall of the adjusting frame 4, and the inner wall of the movable block 201 is provided with a second threaded hole 11 for use with the bidirectional threaded rod 5.

[0033] In this embodiment: the threaded connection between the knob 8 and the support block 203 enables quick replacement and locking of the support block 203. Combined with the precise fit between the movable block 201 and the bidirectional threaded rod 5, the synchronicity and stability of the disassembly mechanism 2 during the adjustment process are ensured, improving the compatibility accuracy and operational reliability of the turbocharger structure 6 of different sizes. The fit between the mounting hole 9 and the first threaded hole 10 makes the knob 8 more securely installed, and the second threaded hole 11 ensures smooth driving of the bidirectional threaded rod 5 and reduces frictional loss.

[0034] Specifically, such as Figure 2 , Figure 6 As shown, a support plate 12 is fixedly connected to the right side of the electric lifting vehicle 1, and a fixing plate 13 is fixedly connected to the front and rear sides of the support plate 12.

[0035] Specifically, such as Figure 6 As shown, a fixing block 14 is fixedly connected to the side of the fixing plate 13 away from the support plate 12, and a fixing ring 15 is fixedly connected to the side of the fixing block 14 away from the fixing plate 13.

[0036] In this embodiment, the rigid connection structure between the support plate 12 and the fixing plate 13 enhances the load-bearing strength of the electric telescopic rod 3, and the combined design of the fixing ring 15 and the fixing block 14 further disperses the force, preventing the adjustment frame 4 from shifting or vibrating during operation, and ensuring the structural stability and safety during the disassembly process.

[0037] Specifically, such as Figure 6 As shown, a slide rod 16 is fixedly connected to the left side of the adjustment frame 4, and the surface of the slide rod 16 is slidably connected to the inner wall of the fixing ring 15.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, an auxiliary bracket 17 is slidably connected to the inner wall of the electric lifting vehicle 1, and a support leg 18 is fixedly connected to the bottom of the auxiliary bracket 17.

[0039] In this embodiment: the sliding cooperation between the slide bar 16 and the fixed ring 15 optimizes the smoothness of the lateral movement of the adjustment frame 4, and the extended design of the auxiliary bracket 17 and the support leg 18 increases the overall support area of ​​the electric lifting vehicle 1, providing additional balance support under complex working conditions, avoiding the risk of equipment overturning, and adapting to the needs of different working environments.

[0040] Working principle: During the use of the electric lifting vehicle 1, the electric lifting vehicle 1 is first moved to the disassembly position of the supercharger structure 6. The rotation of the bidirectional threaded rod 5 drives the movable block 201 to move in the same or opposite direction within the adjusting frame 4, quickly adjusting the spacing of the support blocks 203 to match the size of the supercharger structure 6. Then, the electric lifting vehicle 1 is lowered, and the electric telescopic rod 3 pushes the adjusting frame 4 to precisely insert the support blocks 203 into the pre-fixed position. Finally, the electric lifting vehicle 1 rises, allowing the support blocks 203 to stably support the supercharger structure 6. After precise positioning, disassembly can be performed. The entire process achieves rapid positioning and improves disassembly and assembly efficiency.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
