Description

Technical Field

[0001] The utility model relates to the technical field of impellers, and in particular to an impeller wrench. Background Art

[0002] Impeller refers to the wheel disc with moving blades, which is a component of the impulse turbine rotor, and can also refer to the general term for the wheel disc and the rotating blades installed on it. Impellers can be classified according to their shape and opening and closing conditions. At present, impeller wrenches are required for disassembly and assembly of impellers. Usually, impellers of different models and sizes require different types of wrenches. There are many types of wrenches, especially maintenance personnel often have to carry a variety of wrenches of different models and sizes.

[0003] The Chinese patent with the announcement number CN205136147U discloses a special adjustment wrench for the impeller of a double-suction pump. It includes a cylinder, the inner diameter of which is larger than the outer diameter of the pump shaft of the double-suction pump, and six radially evenly distributed cylinders are arranged at each end of the cylinder, and the six cylinders can be inserted into the six holes on the stop nut of the double-suction pump at the same time; a horizontal handle is arranged on the cylinder. Since the utility model is provided with a cylinder that can be inserted into the six holes on the stop nut of the double-suction pump, the stop nut is screwed by lever action, and since its fulcrum is located inside the stop nut and there are as many as six fulcrums, it will not cause damage to the periphery of the stop nut, nor will it cause damage to the inside of the stop nut. This not only saves material costs, but also can quickly adjust the impeller gap position, provides convenience for maintenance, and reduces maintenance costs.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for cleaning the clamping surface of the impeller wrench during use, and it is not convenient to maintain the friction force, and slipping may occur in actual use. At the same time, the above wrench is not easy to carry, so further improvement is needed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0025] like Figure 1~Figure 4As shown, this embodiment proposes an impeller wrench, including a connecting plate 1, a connecting member 6 is fixedly installed on one side of the connecting plate 1, and both ends of the outside of the connecting member 6 are fixedly connected to mounting shells 7 of different sizes, and mounting plates 8 are fixedly installed on the tops of the two mounting shells 7, one side of the outside of one mounting shell 7 is fixedly connected to a threaded shell 9, and the inside of the threaded shell 9 is connected to a threaded rod 10 through a thread, and the outside of the threaded rod 10 is fixedly connected to a rotating head 11, and the two mounting shells 7 are respectively provided with a first clamping block 12 and a second clamping block 15, the threaded rod 10 is connected to the first clamping block 12 through a bearing, and a fixing rod 14 is fixedly connected to one side of the second clamping block 15, and sliding grooves are provided inside the first clamping block 12 and the second clamping block 15, and the first cleaning plate 13 and the second cleaning plate 16 are respectively slidably connected inside the two sliding grooves.

[0026] In this embodiment, the threaded rod 10 extends to the inside of one of the mounting shells 7, and the bottoms of the first clamping block 12 and the second clamping block 15 are respectively in contact with the insides of the two mounting shells 7, which can facilitate the extension of the threaded rod 10 and the movement of the first clamping block 12.

[0027] In this embodiment, the fixing rod 14 extends to the outside of one of the mounting shells 7 and is fixedly connected to the latter, and one side of the first cleaning plate 13 and the second cleaning plate 16 are respectively in contact with one side of the first clamping block 12 and the second clamping block 15, which can facilitate the sliding of the first cleaning plate 13 and the second cleaning plate 16.

[0028] In this embodiment, the first clamping block 12 and the second clamping block 15 are in the same plane, and the connecting member 6 is configured to be in an arc shape, which can facilitate clamping the impeller.

[0029] During use, when the impeller needs to be clamped, the staff first needs to place the impeller between the second clamping block 15 and the first clamping block 12, and then the staff rotates the rotating head 11 clockwise. The rotating head 11 will synchronously drive the threaded rod 10 to rotate during the rotation process. The threaded rod 10 will synchronously retract and move toward the inside of the threaded shell 9 during the rotation process. Then, the first clamping block 12 will be longitudinally moved by the retracting force of the threaded rod 10. When one side of the first clamping block 12 contacts one side of the impeller, the impeller will be limited by the first clamping block 12 and the second clamping block 15, so that the impellers of different sizes can be limited and clamped.

[0030] When it is necessary to clean the clamping surfaces of the first clamping block 12 and the second clamping block 15, the staff will invert the first clamping block 12 and the second clamping block 15. At this time, the first cleaning plate 13 and the second cleaning plate 16 will slide down inside the sliding groove by their own weight. During the sliding process, the first cleaning plate 13 and the second cleaning plate 16 will respectively clean one side of the first clamping block 12 and the second clamping block 15 to prevent the adhesion of debris, so as to ensure that the friction between the two is not affected. When needed, the first clamping block 12 and the second clamping block 15 will be placed upright, and the first cleaning plate 13 and the second cleaning plate 16 will automatically return to their positions. Example 2

[0031] like Figure 1~Figure 2 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a rotating shaft 2 is movably connected to one side of the connecting plate 1 through a bearing, and the rotating shaft 2 is connected to the connecting plate 1 through a bearing, which can facilitate the rotation of the rotating shaft 2.

[0032] In this embodiment, a handle 3 is fixedly connected to one side of the outer side of the rotating shaft 2, a fixing plate 4 is fixedly connected to one side of the top of the handle 3, and a magnetic attraction plate 5 is embedded in the fixing plate 4 to facilitate the rotation of the handle 3.

[0033] In this embodiment, a magnetic block is embedded in the handle 3, and the magnetic block is connected to the magnetic attraction plate 5 through magnetic connection, which can facilitate the attraction and separation of the two and facilitate the folding of the device.

[0034] In this embodiment, one side of the top of the handle 3 is in contact with one side of the bottom of the fixing plate 4 , and the rotating shaft 2 is located at the bottom of the fixing plate 4 , which can facilitate the separation of the handle 3 from the fixing plate 4 .

[0035] During use, when the device needs to be carried, the staff first needs to bend the handle 3. After the handle 3 is bent under force, it will synchronously drive the rotating shaft 2 to rotate and fit with the connecting plate 1. At this time, the length of the device will be shortened to facilitate the staff to carry it easily. When the staff needs to use the device, the staff needs to bend the handle 3 again to the same horizontal plane as the connecting plate 1, and then the magnetic block inside the handle 3 will be magnetically attracted to the magnetic attraction plate 5, so that the staff can use it handheld.
