[0001] The invention relates to the technical field of motor equipment maintenance, in particular to a motor lifting device for a fan oil station and a motor maintenance system. Background Art

[0002] Originally, when the fan oil station was being repaired, the oil pump motor was disassembled and moved out mainly by vertical transportation by manpower, which consumed a huge amount of manpower.

[0003] When inspecting and replacing the plum blossom pads of the oil pump motor and disassembling and repairing the motor body, the fan oil station needs to remove the motor from the oil station. Due to different unit loads, the oil station and its oil pump motor are of different sizes. If the oil pump motor has a large weight, it is difficult to move it by manpower alone. In addition, the oil pump motor of some oil stations is not in a good position, and it is often difficult for workers to move it. At this time, it is necessary to set up a gantry and use a hoist to lift it, which is time-consuming and laborious. Even if the motor can be moved out by the staff, due to the heavy weight of some motors, it is easy to cause damage to the waist of the staff during the transportation process, which poses certain safety hazards.

[0004] To sum up, the existing fan oil station maintenance work lacks certain professional tools. In order to improve the safety and efficiency of the production and maintenance process, a fan oil station motor lifting device is designed and manufactured to allow the fan oil station oil pump motor disassembly work to be carried out in a safer and more convenient environment, thereby improving work efficiency and reducing personal injuries.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a fan oil station motor lifting device, including a lifting assembly 100, including a labor-saving member 101, an auxiliary member 102 movably arranged below the labor-saving member 101, a support member 103 for providing a certain height, and a connecting member 104 connecting at least two supporting members 103; wherein the labor-saving member 101 is fixedly arranged on the outer wall of the connecting member 104.

[0029] Furthermore, the labor-saving member 101 is mainly used to perform labor-saving operations on the weight of the motor during lifting, mainly to increase the working time and reduce the consumed force, including but not limited to levers, reducers, differentials, etc. for labor-saving operations.

[0030] Preferably, the force-saving member 101 extends outwardly with a chain to connect with the auxiliary member 102, and the auxiliary member 102 is used to further fix the lifting motor to prevent the motor from shaking due to uneven movement speed when the lifting assembly 100 is lifting the motor, thereby preventing a dangerous situation from occurring.

[0031] Preferably, the support member 103 provides a certain height for the labor-saving member 101 and the auxiliary member 102, so as to facilitate lifting the motor from the ground or one height to another height, so as to make the motor escape from its current position.

[0032] Furthermore, the support member 103 itself is an adjustable support member, that is, the support member 103 can be adjusted according to different scenarios to adapt to motor lifting scenarios at different heights.

[0033] Preferably, the connector 104 is used to connect at least two or more supporting members 103, and the connector 104 itself is an adjustable connector, that is, the size of the space occupied by the connector 104 can be adjusted according to different scenarios. In this case, two or more supporting members 103 are close to each other, reducing the floor space of the entire lifting assembly 100.

[0034] In summary, the integrated motor lifting device does not need to re-assume the gantry during use, and uses manual or electric methods to lift the motor with a large weight, thereby preventing injuries to the workers' waists during transportation and potential safety hazards. The motor is further fixed by the auxiliary part 102 to prevent it from falling off during transportation.

[0035] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, and further provides a fan oil station motor lifting device. The labor-saving member 101 includes a first handle 101a, a rotating shaft 101c is fixedly connected inside the first handle 101a, and a transmission block 101d is arranged on the side of the rotating shaft 101c away from the first handle 101a.

[0036] Preferably, a slot is provided inside the first rotating handle 101a, and the slot can be adapted to the motor and the chain. When manual operation is required, the chain can be pulled to drive the first rotating handle 101a to rotate to lift the motor. If the motor itself has a large mass, a belt is installed in the slot to connect to the motor, and the target motor can be lifted by driving the first rotating handle 101a to rotate through the motor.

[0037] Furthermore, the first rotating handle 101a and the rotating shaft 101c are fixedly connected, so that when the first rotating handle 101a rotates, the rotating shaft 101c can be driven to rotate.

[0038] The labor-saving member 101 further includes a first gear 101e drivingly connected to the transmission block 101d, and the number of teeth of the first gear 101e is greater than the number of teeth of the transmission block 101d.

[0039] Preferably, the rotating shaft 101c runs through the entire labor-saving member 101, and the first gear 101e is meshedly connected with the transmission block 101d. When the number of teeth of the first gear 101e is greater than the number of teeth of the transmission block 101d, rotating the first rotating handle 101a rotates the transmission block 101d, and driving the first gear 101e to rotate is a labor-saving operation.

[0040] The force-saving member 101 further includes a second gear 101f coaxially connected to the first gear 101e.

[0041] Preferably, the first gear 101e is rotatably connected to the outer wall of the isolation cover 101b, and the first gear 101e rotates through a shaft fixedly arranged on the outer wall of the isolation cover 101b. The first gear 101e is fixedly connected to the second gear 101f, that is, when the first gear 101e rotates, it synchronously drives the second gear 101f to rotate.

[0042] The labor-saving member 101 further includes a third gear 101g transmission-connected to the second gear 101f, and the third gear 101g is movably connected to the rotating shaft 101c.

[0043] Preferably, the third gear 101g is located between the first gear 101e and the isolation cover 101b, and the third gear 101g is rotatably set on the rotating shaft 101c. The third gear 101g is meshingly connected with the second gear 101f. Then, rotating the first rotating handle 101a will not directly drive the third gear 101e, but will drive the third gear 103g to rotate through the transmission block 101d, the first gear 101e and the second gear 101f.

[0044] The labor-saving member 101 also includes an isolation cover 101b disposed between the third gear 101g and the first rotating handle 101a and movably connected to the rotating shaft 101c. A second rotating handle 101h is movably disposed in the isolation cover 101b. A chain 101k is transmitted in the second rotating handle 101h. The second rotating handle 101h is fixedly connected to the third gear 101g.

[0045] Preferably, a second slot 101i is provided in the second handle 101h, a chain 101k is provided in the second slot 101i, a hook is provided at one end of the chain 101k, the hook is connected to the auxiliary component 102, and the auxiliary component 102 is raised by rotating the first handle 101a, thereby driving the motor to rise.

[0046] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention, further provides a fan oil station motor lifting device. The auxiliary component 102 includes a mounting plate 102a connected to the chain 101k, a clamp 102b movably arranged on the mounting plate 102a, and a fixed shaft 102c for fixing and adjusting the clamp 102b.

[0047] Preferably, the clamps 102b are slidably disposed on the end surface of the mounting plate 102a, and at least two groups of clamps 102b are symmetrically disposed, both of which are slidably disposed on the end surface of the mounting plate 102a.

[0048] Furthermore, the fixed shaft 102c is transmission-disposed between the two clamps 102b, and the two clamps 102b between the same fixed shaft 102c can be moved closer to each other by rotating the fixed shaft 102c, thereby reducing the distance between the clamps 102b to accommodate different motors.

[0049] The support member 103 includes a support leg 103a and a height-increasing rod 103b movably disposed on the inner wall of the support leg 103a.

[0050] Preferably, a first through hole 103c penetrating the leg 103a is provided on the outer wall of the support leg 103a, and a second through hole 103d penetrating the height-increasing rod 103b is provided on the outer wall of the support leg 103a. The apertures of the first through hole 103c and the second through hole 103d are equal. When the support leg 103a and the height-increasing rod 103b are fixed, the first through hole 103c and the second through hole 103d are coaxial. The first through hole 103c and the second through hole 103d are fixed by a pin 103e. A fixing pin 103f is also provided at a position outside the first through hole 103c and the second through hole 103d to prevent the pin 103e from falling off from the first through hole 103c and the second through hole 103d.

[0052] Preferably, the first connecting plate 104a is slidably connected to the second connecting plate 104b.

[0053] In summary, when the motor needs to be lifted, rotate the fixed shaft 102c to move the two clamps 102b to the appropriate position, lift the motor, and after completing the maintenance work on the motor, slide the second connecting plate 104b into the first connecting plate 104a to retract the lifting device.
