[0030] The core of the present utility model is to provide a pump shaft lifting tool for a vertical barrel pump to improve the stability of pump shaft lifting.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0032] During the comprehensive disassembly and inspection of the vertical barrel pump, it is necessary to adjust the position of the pump shaft 500 so that the impeller is located in the middle position between two adjacent partitions. During this process, it is necessary to first lift the pump shaft 500 to simplify the installation and disassembly process and improve work efficiency.

[0033] The traditional method of lifting the pump shaft 500 is generally to install a lifting ring at the head of the pump shaft 500, and then lift the pump shaft 500 through a hoisting device such as a crane. However, during the process of lifting the pump shaft 500, the pump shaft 500 is prone to shaking, making it difficult to ensure stability and having a risk of damaging the pump shaft 500.

[0034] Therefore, as Figure 1 shown, an embodiment of the present utility model discloses a pump shaft lifting tool for a vertical barrel pump, including a support member 100, a connecting member 300, and a lifting mechanism 400.

[0035] Among them, the support member 100 is supported on the bracket 200 of the vertical barrel pump, and a through hole 101 is provided on the support member 100. Moreover, the connecting member 300 has two opposite ends. For the convenience of understanding, the two ends of the connecting member 300 are respectively defined as the first end and the second end. The first end of the connecting member 300 passes through the through hole 101 of the support member 100 and is connected to the pump shaft 500 of the vertical barrel pump. The second end of the connecting member 300 is connected to the lifting mechanism 400. The lifting mechanism 400 stably lifts the pump shaft 500 of the vertical barrel pump. At the same time, the connecting member 300 is made of a rigid member, which can prevent the pump shaft 500 from shaking during the lifting process and effectively protects the pump shaft 500.

[0036] Furthermore, a threaded hole is provided at the end of the pump shaft 500. The first end of the connecting member 300 extends into the threaded hole at the end of the pump shaft 500 and is threadedly engaged with the threaded hole of the pump shaft 500 to ensure the reliability of the connection between the connecting member 300 and the pump shaft 500. It should be noted that the threaded hole is the original connection hole at the end of the pump shaft 500 and does not need to be specially set. That is, the first end of the connecting member 300 can be directly connected to the threaded hole of the pump shaft 500, which is more convenient and fast and saves costs.

[0037] Furthermore, as Figure 1 shown, the support member 100 includes a cross beam 102 erected on the bracket 200 of the vertical barrel pump. When the motor of the vertical barrel pump is removed, the cross beam 102 can be erected on the bracket 200. Among them, the cross beam 102 can be made of but not limited to channel steel, and the cross beam 102 can be fixed to the brackets 200 at both ends by bolts to ensure the stability of the lifting platform. At the same time, the through hole 101 is opened on the cross beam 102, and the connecting member 300 is a rod-shaped structure. The outer diameter of the connecting member 300 is smaller than the inner diameter of the through hole 101, so that when the lifting mechanism 400 lifts the pump shaft 500 through the connecting member 300, the connecting member 300 can freely pass through the through hole 101, thus ensuring the stable lifting of the pump shaft 500.

[0038] Furthermore, for the convenience of disassembly and assembly of the lifting mechanism 400, the lifting mechanism 400 is arranged on the support member 100 and is connected to the support member 100 by bolts to ensure the stability of the lifting mechanism 400. At the same time, the second end of the connecting member 300 is detachably connected to the lifting mechanism 400, so that the lifting mechanism 400, the support member 100 and the connecting member 300 are convenient for quick disassembly and assembly, improving the work efficiency.

[0039] Furthermore, the connecting member 300 can be a lead screw, and at the same time, the lifting mechanism 400 can adopt a transmission mechanism that cooperates with the lead screw, so as to drive the lead screw to move linearly through the transmission mechanism, and further achieve the purpose of lifting the pump shaft 500. Among them, the transmission mechanism can be made of but not limited to a lead screw motor to improve the lifting efficiency of the pump shaft 500.

[0040] Furthermore, as Figure 1 shown, in order to improve the stability of the pump shaft 500 during the lifting process and avoid shaking, in a specific embodiment, the lifting mechanism 400 may adopt a jack 401, so as to ensure that the pump shaft 500 is lifted stably and slowly, thereby playing a further role in protecting the pump shaft 500. Specifically, the jack 401 includes a base 4011 and a pressure-bearing member 4012 disposed on the base 4011, and both the base 4011 and the pressure-bearing member 4012 are hollow structures. At the same time, the orthographic projection area of the base 4011 is larger than the orthographic projection area of the through hole 101, so that the jack 401 can be connected and fixed to the hole edge of the through hole 101 through the base 4011, thereby realizing a reliable connection between the jack 401 and the support member 100, and further ensuring the stability of the lifting of the pump shaft 500.

[0041] Furthermore, as Figure 1 shown, the second end of the connecting member 300 can pass through the base 4011 and the pressure-bearing member 4012 and be connected and fixed by a fastener 301. Specifically, the second end of the connecting member 300 is provided with a threaded portion that is threadedly engaged with the fastener 301, and the fastener 301 can be, but is not limited to, a lock nut. The outer diameter of the fastener 301 is larger than the aperture of the central hole of the pressure-bearing member 4012, so that when the fastener 301 is threadedly engaged with the second end of the connecting member 300, the second end of the connecting member 300 can be connected and fixed to the jack 401, ensuring the reliability of the connection between the second end of the connecting member 300 and the jack 401. In this embodiment, preferably, the lifting mechanism 400 can be, but is not limited to, a hollow jack 401. By pressurizing the hollow jack 401, the connecting member 300 can be lifted, and then the pump shaft 500 can be slowly lifted, ensuring the stability of the lifting of the pump shaft 500.
