Technical Field

[0001] This utility model relates to the field of vertical pump technology, and in particular to a jacking tool for disassembling a vertical pump. Background Technology

[0002] Vertical pumps are centrifugal pumps installed vertically. They have a compact structure, occupy a small area, and are widely used in civil and industrial fields, including urban water supply and drainage, air conditioning and HVAC circulation, petrochemicals, pharmaceuticals, and papermaking. Their flexibility and reliability make them important equipment for fluid transportation.

[0003] When a vertical pump malfunctions, disassembly and repair are necessary. During the disassembly and repair of a vertical pump, the removal of the shaft system is a critical step. Currently, hydraulic jacks or simple pry bars are generally used for shaft disassembly. However, using hydraulic jacks is problematic because the equipment is heavy and its placement on-site is limited. Using simple pry bars can easily lead to uneven stress on the shaft, causing problems such as pump shaft deformation and damage to the sealing surfaces. Furthermore, the operation is time-consuming and labor-intensive, severely impacting repair efficiency and equipment safety.

[0004] In summary, how to provide a top-shaft tool that is simple in structure, easy to operate, and provides uniform shaft force has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0045] This utility model discloses a jacking tool for disassembling a vertical pump. It has a simple structure, is easy to operate and saves effort. When jacking, the pump shaft is subjected to uniform force, avoiding deformation or damage to the pump shaft caused by uneven thrust.

[0046] 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.

[0047] See Figures 1 to 10 This utility model discloses a vertical pump disassembly tool for a jacking shaft, comprising a base 1, a screw 2, a jacking part 3, and an operating lever 4. The base 1 has a first threaded hole 104 extending along the height direction, at least penetrating the top of the base 1 for connection with the screw 2. The screw 2 is threaded into the first threaded hole 104. The jacking part 3 is connected to the end of the screw 2 away from the first threaded hole 104, and its position away from the screw 2 supports the bottom of the pump shaft. The operating lever 4 is connected to the jacking part 3 and drives the jacking part 3 and the screw 2 to rotate. Because the screw 2 is threaded into the base 1, rotating the screw 2 allows for axial feed, pushing the jacking part 3 to move linearly along the height direction, thus achieving the jacking of the pump shaft by the jacking part 3.

[0048] The height direction is shown below. Figure 3 As shown in the diagram, screw 2 is machined from high-strength alloy steel.

[0049] This utility model discloses a jacking tool for dismantling a vertical pump. It comprises a base 1, a screw 2, a pressing part 3, and an operating rod 4. The base 1 provides stable support, the screw 2 is threadedly connected to the base 1, and the pressing part 3 is fixedly connected to the screw 2. When the operating rod 4 drives the pressing part 3 to rotate, the screw 2 drives the pressing part 3 to move linearly along the axial direction of the screw 2, thereby lifting the pump shaft and achieving the pushing of the pump shaft. This utility model's jacking tool for dismantling a vertical pump has a simple structure, is easy to operate and labor-saving, and can achieve the dismantling and removal of the shaft system of a vertical pump. Furthermore, the pressing part 3 lifts the shaft system, ensuring uniform force on the pump shaft during pushing and preventing deformation of the pump shaft.

[0050] Specifically, refer to Figures 2 to 5The base 1 includes a main body 103 and a flange 101, with the flange 101 located at the end of the main body 103 away from the screw 2. To improve the stability of the support, the outer edge dimension of the flange 101 is larger than the outer edge dimension of the main body 103 in the projection onto a plane perpendicular to the height direction. In a specific embodiment, the main body 103 has a cylindrical structure, and the flange 101 has a disc-shaped structure, with the diameter of the flange 101 being larger than the outer diameter of the main body 103.

[0051] To save on processing costs, the first threaded hole 104 is provided to penetrate the main body 103, such as... Figure 5 As shown, this facilitates processing and manufacturing, saving costs. To improve the stability of the support, the hole axis of the first threaded hole 104 is set along the center line of the main body 103. A first thread 105 is provided in the first threaded hole 104, and a second thread 201 is provided on the screw 2. The first thread 105 and the second thread 201 are matched to realize the threaded connection between the screw 2 and the base 1.

[0052] To facilitate lifting and handling, the main body 103 is provided with lifting holes 102, such as... Figure 3 and Figure 5 As shown. Preferably, there are two lifting holes 102, which are symmetrically arranged on the main body 103 to facilitate stable lifting.

[0053] In one embodiment, the top pressure part 3 includes a top pressure plate 301, one end face of which is connected to the screw 2, and the other end face is used to contact the bottom surface of the pump shaft. The top pressure plate 301 can be welded to the top of the screw 2, threaded to the top of the screw 2, or other commonly used connection methods, which are not limited here. The top pressure plate 301 is preferably a circular steel plate.

[0054] To improve the support stability of the pump shaft, a conical top head 302 is provided on the end face of the top pressure plate 301 away from the screw 2, as shown in the reference. Figures 6 to 9 Understandably, the conical top head 302 is conical, and the top cone angle of the conical top head 302 is the same as the top cone angle of the auxiliary limiting hole at the end of the pump shaft. This improves the fit between the contact surface of the top pressure plate 301 and the bottom surface of the pump shaft, and improves the stability of the contact position between the top pressure plate 301 and the pump shaft.

[0055] To facilitate connection with the operating lever 4, a connecting part 303 is provided on the side of the pressure plate 301, and the operating lever 4 is fixedly or detachably connected to the connecting part 303. By connecting the operating lever 4 to the side of the pressure plate 301, the operator can easily rotate the screw 2 via the pressure plate 301.

[0056] To improve ease of operation, at least two connecting parts 303 are provided, and multiple connecting parts 303 are evenly distributed around the axis of the top pressure plate 301, thereby allowing for the provision of multiple operating levers 4, which improves the stability and convenience of driving the top pressure plate 301 to rotate.

[0057] In one specific embodiment, the connecting part 303 is a second threaded hole, and the operating rod 4 is threaded into the second threaded hole. This connection method facilitates the assembly and disassembly of the operating rod 4. In another specific embodiment, the connecting part 303 is a through hole, and the operating rod 4 is interference-fitted into the through hole; or, the operating rod 4 is inserted into the through hole and then welded to the top pressure plate 301.

[0058] For ease of operation, the operating lever 4 includes an operating end 401 and a connecting end 402, such as... Figure 1 and Figure 10 As shown, the connecting end 402 is connected to the top pressing part 3, and the operating end 401 is located at the end of the operating lever 4 away from the top pressing part 3. The operating end 401 is used by the operator to grip and operate the lever. To improve anti-slip capability, the surface of the operating end 401 is provided with anti-slip patterns. The anti-slip patterns can be mesh patterns or other forms or structures; no limitation is made here, as long as the patterns have an anti-slip effect, they are within the protection scope. The operating end 401 and the connecting end 402 can be directly connected or connected through an optical axis segment; no limitation is made here.

[0059] In one embodiment, two operating levers 4 are provided, and the operating levers 4 are round rods. The connecting part 303 is a threaded hole. In use, the operating lever 4 is screwed into the threaded hole. By rotating the operating lever 4 with both hands, the top pressing part 3 and the screw 2 are driven to rotate. The screw 2 moves axially, and the top pressing part 3 pushes the bottom end face of the pump shaft to realize the ejection and disassembly of the shaft system.

[0060] When using the vertical pump disassembly tool of this utility model, first, place the flange 101 of the base 1 on a flat ground below the pump body, and adjust the position so that the conical top 302 is aligned with the center of the bottom end face of the pump shaft; then connect the operating rod 4 to the pressure plate 301, and rotate the two operating rods 4 simultaneously with both hands to drive the screw 2 to feed axially, and the conical top 302 slowly pushes the pump shaft; continue to rotate the operating rod 4 until the pump shaft is completely pushed out of the pump body, completing the disassembly operation; finally, rotate the operating rod 4 in the opposite direction to retract the screw 2 and remove the tool.

[0061] The jacking tool for dismantling a vertical pump of this invention uses a screw drive to push the pump shaft, which is labor-saving and provides stable and controllable jacking force. During jacking, the surface of the jacking plate 301 close to the pump shaft fits tightly against the end face of the pump shaft, ensuring uniform force on the bottom end face of the pump shaft and preventing deformation or damage caused by uneven force. The jacking tool has a simple structure and small size, making it easy to transport and operate on site, and can significantly improve the efficiency of vertical pump dismantling.
