Description

Technical Field

[0001] The utility model relates to the technical field of cranking, in particular to a portable cranking tool for small and medium-sized water pump units. Background Art

[0002] In order to prevent the permanent deformation of the main shaft of the pump unit due to long-term storage under the action of gravity during the non-operation period, the motor rotor should be regularly rotated and maintained according to the operation and maintenance technical requirements. In addition, the parts of the unit that have not been in operation for a long time are prone to rust, resulting in a large starting torque, which is easy to get stuck during startup.

[0003] The traditional cranking process requires manual rotation of the motor water pump shaft for cranking. However, for small and medium-sized vertical and horizontal pump units, since the rotating parts of the motor and water pump impeller are heavy, if the traditional cranking process is used, there are defects such as low work efficiency, high labor intensity, difficult operation, and unsafe operation. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a portable small and medium-sized water pump unit cranking tool, which can not only assist cranking personnel to perform cranking work more conveniently, safely and efficiently, but also has a wide range of applications.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A portable turning tool for small and medium-sized water pump units comprises a left clamping arm and a right clamping arm, wherein the connecting end of the right clamping arm is fixedly connected to a connecting sleeve, and the connecting end of the left clamping arm is fixedly connected to an adjusting arm inserted into the connecting sleeve, and the adjusting arm can be pushed and pulled relative to the connecting sleeve to adjust the size of the clamping space formed by the left clamping arm and the right clamping arm, and the connecting sleeve is also provided with a locking piece for locking it with the adjusting arm, and a handle is also provided on the outer side of the left clamping arm or the outer side of the right clamping arm.

[0007] Preferably, a resistance contact portion is further provided on the clamping inner sides of the left clamping arm and the right clamping arm.

[0008] Preferably, the resistance contact portion is a nylon pad.

[0009] Preferably, the locking member is a locking top screw.

[0010] Preferably, both the left clamping arm and the right clamping arm are arc-shaped clamping arms.

[0011] Preferably, the handle portion is fixedly connected to the outer side of the right clamping arm.

[0012] Preferably, the adjusting arm is a straight arm.

[0013] Preferably, the right clamping arms are provided in two groups in parallel, the two groups of right clamping arms are fixed by a connecting arm, and each group of right clamping arms is connected to a left clamping arm.

[0014] The utility model adopts the above technical solution, and has the advantages that the portable small and medium-sized water pump unit turning tool can be adapted to the clamping of unit rotors of different sizes through the coordination of the left clamping arm, the right clamping arm, the connecting sleeve, the adjusting arm and other structures; when the above turning tool is used to assist in the turning work, it can not only save trouble and safely realize the rotation turning of the unit rotor, but also has high work efficiency.

[0015] Among them, the nylon pads in the left and right clamping arms can not only increase the friction between the turning tool and the unit rotor, so that the turning tool and the unit rotor are more stably combined, but also not easy to damage the unit rotor. The arc-shaped clamping arm is used, which makes it difficult for the turning tool to fall off and the turning process is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0019] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0020] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment are included in at least one embodiment of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments in a suitable manner.

[0021] like Figure 1As shown, in this embodiment, the portable small and medium-sized water pump unit turning tool includes a left clamping arm 1 and a right clamping arm 2, the connecting end of the right clamping arm 2 is fixedly connected to a connecting sleeve 3, the connecting end of the left clamping arm 1 is fixedly connected to an adjusting arm 4 inserted into the connecting sleeve 3, the adjusting arm 4 can be pushed and pulled relative to the connecting sleeve 3 to adjust the size of the clamping space formed by the left clamping arm 1 and the right clamping arm 2, the connecting sleeve 3 is also provided with a locking piece 5 for locking it with the adjusting arm 4, and the outer side of the left clamping arm 1 or the outer side of the right clamping arm 2 is also provided with a handle 6.

[0022] When in use, the size of the clamping space is adjusted according to the size of the unit rotor. Specifically, the left clamping arm 1 is first pulled to move the adjusting arm 4 to the left relative to the connecting sleeve 3, until the left clamping arm 1 and the right clamping arm 2 can be clamped into the two sides of the unit rotor, and then the left clamping arm 1 is pushed to move the adjusting arm 4 to the right relative to the connecting sleeve 3, until the left clamping arm 1 and the right clamping arm 2 clamp the unit rotor, and then the adjusting arm 4 and the connecting sleeve 3 are locked by the locking member 5, so that the turning tool is firmly clamped on the unit rotor. When the turning tool is used, the operator can more conveniently give the unit rotor a larger rotational force to turn the tool by holding the handle 6. Compared with the traditional turning operation, the turning tool of the present application is used to assist the turning work, which is not only convenient and safe, but also has high work efficiency.

[0023] In one embodiment, the inner side of the left clamping arm 1 and the right clamping arm 2 is further provided with a resistance contact portion 7. Further, the resistance contact portion 7 can be, but is not limited to, a nylon pad, and can be specifically bonded. Such a configuration can increase the friction between the turning tool and the unit rotor, so that the combination of the two is more stable, thereby facilitating stable turning work.

[0024] In one of the embodiments, the locking member 5 may be, but is not limited to, a locking jack screw or a locking bolt, and the adjusting arm may be tightened and loosened by rotating the locking jack screw.

[0025] In one embodiment, the left clamping arm 1 and the right clamping arm 2 are both arc-shaped clamping arms, which provide a better connection stability with the unit rotor.

[0026] In one embodiment, the handle portion 6 is fixedly connected to the outer side of the right clamping arm.
