[0002] A turbocharger pump is a pressure energy recovery device used in the chemical industry, where the medium is liquid. The turbocharger pump is mainly composed of an inner casing and an outer casing. Since the inner casing has multiple layers of sealing rings and retaining rings on its surface, it has strong sealing and high pressure, making it difficult to assemble with the outer casing.

[0003] At present, when disassembling and assembling a turbocharger pump, it is often necessary to manually install or pull the inner box body into or out of the shell. However, during the disassembly process, swinging is often unavoidable, and the adjustment process requires time and manpower. The whole process not only requires a lot of time and manpower, but also has many safety hazards. The surface of the inner box body and the outer shell are prone to damage, resulting in economic loss and seriously affecting the stable operation of the turbocharger pump.

[0004] Therefore, it is urgent to propose a corresponding solution to the problem that the inner casing and the outer casing of the turbocharger pump are difficult to assemble manually, the disassembly and assembly process not only requires a lot of time and manpower, but also has many safety hazards. Summary of the invention

[0005] The purpose of the present invention is to overcome the problem in the prior art that the inner casing and the outer casing of a turbocharger pump are difficult to assemble manually, the disassembly and assembly process not only requires a lot of time and manpower, but also has many safety hazards, and the surfaces of the inner casing and the outer casing are easily damaged, resulting in loss of economic benefits and seriously affecting the stable operation of the turbocharger pump.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a turbocharger pump disassembly and assembly tool, comprising an inner box body tooling that can be detachably connected to the inner box body of the turbocharger pump and a screw rod drivingly connected to the inner box body tooling, wherein the inner box body tooling includes a nut that cooperates with the screw rod thread, and the screw rod can be driven to rotate so that the inner box body tooling drives the inner box body to rise and fall along the extension direction of the screw rod, so as to separate or assemble the inner box body and the housing of the turbocharger pump.

[0007] In some embodiments, the inner box body tooling includes a mounting ring that can be connected to the top of the inner box body by fasteners and a plurality of first ribs connected to the mounting ring at one end and extending in a direction away from the inner box body, and the other end of the first ribs is connected to the nut.

[0008] In some embodiments, a plurality of the first ribs are spaced apart from each other along the circumference of the mounting ring, and the nut and the mounting ring are coaxial with each other.

[0009] In some embodiments, it further includes a housing tooling that can be detachably connected to the housing. The housing tooling includes a limiting component that is axially limited and cooperates with the lead screw. The lead screw sequentially passes through the limiting component and the nut, so that when the lead screw is driven to rotate self - axially, the inner cartridge tooling can move up and down relative to the housing along the lead screw.

[0037] In order to overcome the problem in the prior art that the inner casing and the outer casing of the turbocharger pump are difficult to assemble manually, the disassembly and assembly process not only requires a lot of time and manpower, but also has many safety hazards. The surface of the inner casing and the outer casing are easily damaged, resulting in economic loss and seriously affecting the stable operation of the turbocharger pump.

[0038] Reference Figures 1 to 8 As shown, the present invention discloses a turbocharger pump disassembly and assembly tool.

[0039] Embodiment 1

[0040] The turbocharger pump disassembly and assembly tool comprises an inner casing body tooling 2 which can be detachably connected to an inner casing body 1 of the turbocharger pump and a screw rod 3 which is transmission-connected to the inner casing body tooling 2, wherein the inner casing body tooling 2 comprises a nut 21 which is threadably matched with the screw rod 3, and the screw rod 3 can be driven to rotate so that the inner casing body tooling 2 drives the inner casing body 1 to rise and fall along the extension direction of the screw rod 3, so as to separate or assemble the inner casing body 1 and the housing 4 of the turbocharger pump.

[0041] Specifically, Figures 1 to 3As shown, the inner casing tooling 2 of the turbocharger pump disassembly and assembly tool can be detachably connected to the inner casing 1 of the turbocharger pump, and the nut 21 of the inner casing tooling 2 is sleeved on the lead screw 3 and threadedly engaged. When the lead screw 3 is driven to rotate, under the action of the limiting component, the inner casing tooling 2 threadedly engaged with the lead screw 3 can move up and down along the extension direction of the lead screw 3, thereby driving the inner casing 1 to move up and down, so as to realize the assembly or disassembly of the inner casing 1 and the casing 4 of the turbocharger pump. There is no need for manual assembly, effectively saving manpower and time, avoiding potential safety hazards, and improving economic benefits.

[0042] When assembling the inner casing 1 and the casing 4, first, the inner casing 1 can be hoisted to the top of the casing 4 and aligned with the casing 4. Then, the inner casing tooling 2 is detachably connected to the inner casing 1, and the lead screw 3 is passed through the nut 21 threadedly engaged with it (as Figure 2 shown). Furthermore, the lead screw 3 can be driven to rotate, so that the nut 21 can move downward along the extension direction of the lead screw 3, thereby driving the inner casing 1 to descend, making the inner casing 1 move towards the casing 4 for assembly until the inner casing 1 completely extends into the casing 4 and the assembly is completed (as Figure 3 shown). On the contrary, when disassembling and separating the inner casing 1 and the casing 4, the lead screw 3 can be driven to rotate in the reverse direction, so that the inner casing 1 moves in the direction away from the casing 4 for disassembly and separation until the inner casing 1 and the casing 4 are completely separated and the disassembly and separation are completed.

[0043] Embodiment 2

[0044] This embodiment includes all the contents of Embodiment 1. And in this embodiment, as shown in combination with Figure 4 and Figure 5 , the inner casing tooling 2 includes a mounting ring 22 that can be connected to the top end of the inner casing 1 through a fastener and a plurality of first rib plates 23 with one end connected to the mounting ring 22 and extending in the direction away from the inner casing 1. The other end of the first rib plate 23 is connected to the nut 21.

[0045] Specifically, as shown in combination with Figure 4 and Figure 5 , through holes can be provided on the mounting ring 22, and then the inner casing tooling 2 can be connected to the top end of the inner casing 1 by passing a fastener through the through holes. Among them, the diameter of the mounting ring 22 is not greater than the diameter of the inner casing 1 to avoid hindering the assembly of the inner casing 1 into the casing 4. And, the plurality of first rib plates 23 can be arc-shaped plates, and the ends away from the inner casing 1 can be convergently connected to the nut 21.

[0046] Furthermore, referring to Figure 4As shown, a plurality of first rib plates 23 are arranged at intervals along the circumferential direction of the mounting ring 22, so that when the inner box body 1 is lifted, it can be stressed in all directions, avoiding shaking during the lifting and lowering process of the inner box body 1, and the nut 21 and the mounting ring 22 are coaxial with each other.

[0047] Embodiment III

[0048] This embodiment includes all the contents of Embodiment I. And in this embodiment, with reference to Figures 1 to 3 As shown, the turbocharger pump disassembly and assembly tool further includes a housing tooling 5 that can be detachably connected to the housing 4. The housing tooling 5 includes a limiting component that is axially limited and cooperated with the lead screw 3. The lead screw 3 sequentially passes through the limiting component and the nut 21, so that when the lead screw 3 is driven to rotate, the inner box body tooling 2 can move up and down relative to the housing 4 along the lead screw 3.

[0049] Specifically, with reference to Figures 1 to 3 As shown, a housing tooling 5 can be detachably connected to the housing 4, and the limiting component is connected to the lead screw 3 to limit the axial direction of the lead screw 3. Therefore, when the lead screw 3 is driven to rotate, the inner box body 1 can move along the extending direction of the lead screw 3 under the drive of the inner box body tooling 2. At the same time, due to the limiting effect of the limiting component, when the lead screw 3 rotates, the housing tooling 5 remains stationary, so that the inner box body tooling 2 can move up and down relative to the housing 4 along the extending direction of the lead screw 3, thereby separating or assembling the inner box body 1 and the housing 4.

[0050] Furthermore, with reference to Figure 8 As shown, a radially protruding connecting block 31 can be arranged on the circumferential direction of the lead screw 3. And in combination with Figure 2 and Figure 3 As shown, the limiting component can be connected to the connecting block 31, and then the lead screw 3 is fixed axially. When the lead screw 3 is driven to rotate, the housing tooling 5 can limit the axial position of the lead screw 3, so that when the inner box body tooling 2 drives the inner box body 1 to move along the extending direction of the lead screw 3, it is more stable.

[0051] Among them, in combination with Figure 2 and Figure 3 As shown, the limiting component includes a limiting seat 51 sleeved on the lead screw 3 and a limiting cover 52 connected to the limiting seat 51. An annular sunk platform is formed around the lead screw 3 inside the limiting seat 51, and the annular sunk platform and the bottom end of the limiting cover 52 together define an installation space for fixing the connecting block 31.

[0052] Specifically, the radial size of the annular sunk platform is adapted to the connecting block 31. After the lead screw 3 passes through the limit seat 51, due to the setting of the annular sunk platform, the connecting block 31 can be blocked, so as to axially fix the lead screw 3. And the top of the limit seat 51 can be connected to the limit cover 52. The limit cover 52 and the annular sunk platform can form an installation space for fixing the connecting block 31, and a gap is formed between the installation space and the connecting block 31, so that the lead screw 3 can rotate freely. With such a setting, when the lead screw 3 is driven to rotate self - axially, due to the combined action of the limit seat 51 and the limit cover 52, the housing tooling 5 and the lead screw 3 are axially fixed and immovable, while the inner box body tooling 2 can move up and down relative to the housing 4 along the extension direction of the lead screw 3.

[0053] Further, as Figure 7 shown, the outer peripheral wall of the limit seat 51 can be provided with an annular step with an opening facing away from the lead screw 3. The vertical surface of the annular step can form a thread, so that the limit cover 52 can be screwed onto the limit seat 51 and abut against the horizontal plane of the annular step, avoiding loosening between the limit seat 51 and the limit cover 52 during disassembly and assembly, resulting in damage.

[0054] Meanwhile, in combination with Figure 6 and Figure 7 shown, the housing tooling 5 further includes a plurality of mounting plates 53 that can be connected to the top end of the housing 4, and a plurality of second rib plates 54 with one end connected to the mounting plates 53 and extending in a direction away from the housing 4. The other end of the second rib plate 54 is connected to the limit assembly.

[0055] Specifically, in combination with Figure 6 and Figure 7 shown, the mounting plates 53 of the housing tooling 5 can be connected to the top end of the housing 4 through bolts. And the plurality of second rib plates 54 connected to the mounting plates 53 can be arc - shaped plates. The radian of the second rib plate 54 can be greater than the radian of the first rib plate 23. On the one hand, it can enhance the supporting force. On the other hand, the housing 4 is sleeved on the outside of the inner box body 1, and the plurality of second rib plates 54 converge and are connected to the limit assembly. To ensure that the limit assembly and the nut 21 are coaxial, the radian of the second rib plate 54 needs to be greater than the radian of the first rib plate 23.

[0056] Further, referring to Figure 6 shown, the plurality of mounting plates 53 can be arranged at intervals along the circumferential direction of the top of the housing 4, further reducing the cost. And the center of the limit assembly and the centers of the plurality of mounting plates 53 are coaxial with each other, so that the limit assembly and the nut 21 are coaxial with each other, avoiding misalignment and being unable to align the inner box body 1 and the housing 4. Of course, in other embodiments, the mounting plate 53 can also be set as a ring as long as it can be connected to the housing 4.

[0057] Meanwhile, in combination with Figure 2 and Figure 3As shown, the vertical height of the limit component from the housing 4 is higher than the vertical height of the nut 21 from the bottom end of the inner casing 1. It can be understood that the connection position of the limit component to the connecting portion 31 of the lead screw 3 can be higher than the vertical height of the nut 21 from the bottom end of the inner casing 1. With such a setting, when it is necessary to disassemble and separate the inner casing 1 from the housing 4, the inner casing tooling 2 can directly drive the inner casing 1 to move along the lead screw 3 in a direction away from the housing 4, avoiding the housing tooling 5 from blocking the upward separation of the inner casing 1, and there is no need to disassemble the housing tooling 5, so that the limit component can continue to limit the axial direction of the lead screw 3, and the inner casing 1 and the housing 4 can be stably disassembled and separated, avoiding shaking.

[0058] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention. Including any suitable combination of each specific technical feature. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods. But these simple modifications and combinations should also be regarded as the content disclosed by the present invention and all fall within the protection scope of the present invention.
