[0042] 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.

[0043] 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.

[0044] 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 is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0045] Example 1

[0046] Reference Figure 1 to Figure 3 , is the first embodiment of the present invention, which provides a motor reducer maintenance tool, including a lifting unit 100, including a guide member 101, a first sliding member 102, a pushing block 103, a lifting rod 104, a rolling member 105 and a supporting platform 106; a slidable first sliding member 102 is arranged on the outer side of the guide member 101; the pushing block 103 is connected to the surface of the first sliding member 102, and a lifting rod 104 is arranged above the pushing block 103; the running direction of the first sliding member 102 is perpendicular to the lifting rod 104, the rolling member 105 is arranged at the top of the lifting rod 104, and the supporting platform 106 is arranged above the rolling member 105.

[0047] In this embodiment, the support platform 106 provided can be used to support the reducer, and the reducer is installed above the support platform 106. Due to the deadweight of the reducer, the bottom of the support platform 106 will conflict with the surface of the support frame at this time, so that the reducer is fixed above the support frame; the first sliding member 102 is moved to drive the pushing block 103 to move, and the end surface of the pushing block 103 will push the lifting rod 104 to move in a direction perpendicular to the pushing block 103 while moving; as the lifting rod 104 moves, the rolling member 105 provided on its top moves synchronously with the lifting rod 104, and then the bottom of the support platform 106 is separated from the surface of the support frame; at this time, the friction between the rolling member 105 and the support platform 106 is rolling friction, and it is more labor-saving to rotate the support platform 106 at this time, and the position of the reducer on the support frame can be flexibly adjusted.

[0048] It should be noted that the guide member 101 is adapted to the first sliding member 102 , and the guide member 101 guides the movement of the first sliding member 102 , so that the first sliding member 102 reciprocates along the axial direction of the guide member 101 .

[0049] Specifically, the first sliding member 102 and the pushing block 103 can be fixed by bolt connection; thus, the pushing block 103 can move synchronously with the first sliding member 102; during the movement of the pushing block 103 in the horizontal direction, its end surface gradually squeezes the bottom of the lifting rod 104 and pushes it to move.

[0050] Preferably, while the lifting rod 104 is moving, it will push the top of the rolling element 105 to move in the direction close to the support platform 106; when the roller arranged inside the rolling element 105 contacts the bottom surface of the support platform 106, and then the lifting rod 104 continues to move, it will synchronously drive the support platform 106 to move, so that there is a certain gap between the bottom of the support platform 106 and the surface of the support frame; at this time, it can be relatively easy to rotate the support platform 106, so as to better facilitate the staff to adjust the angle of the reducer and better facilitate the staff to repair and maintain the reducer.

[0051] Specifically, the movement of the lifting rod 104 can push the rolling element 105 to contact the bottom of the supporting platform 106 , thereby realizing the rotation of the supporting platform 106 .

[0052] In summary, the coordination between the rolling parts and the support platform can not only allow technicians to approach various maintenance components more easily, improving the safety and comfort of operations, but also flexibly adjust the position of the reducer to facilitate all-round inspection and maintenance, effectively reducing the operational inconvenience caused by the fixed position.

[0053] Example 2

[0054] Reference Figure 1 to Figure 5 , which is a second embodiment of the present invention, includes a transmission unit 200, including a support frame 201, a screw member 202 arranged on the inner side of the support frame 201, a second sliding member 203 arranged on the outer side of the screw member 202, and a gear member 204 coaxially arranged with the support frame 201; the guide member 101 is penetrated through the side wall of the support frame 201.

[0055] In this embodiment, the support frame 201 is a hollow ring structure, and at least three groups of support legs are provided at the bottom of the support frame 201, so as to ensure that the support frame 201 is stably placed on the bottom surface.

[0056] It should be noted that the screw member 202 passes through the support frame 201 and extends into the interior thereof, and one end of the screw member 202 is located outside the support frame 201, so that it is more convenient for the staff to use tools to drive the screw member 202 to rotate; at the same time, a support block is provided inside the support frame 201 to ensure that the screw member 202 is located inside the support frame 201 and rotates smoothly.

[0057] Specifically, the second sliding member 203 meshes with the gear member 204, and the inner ring side wall of the gear member 204 contacts the hollow inner wall of the support frame 201, so that the gear member 204 can move smoothly along the axis direction of the support frame 201, ensuring stable and efficient motion transmission.

[0058] Furthermore, the interior of the support frame 201 is a hollow structure, and the support frame 201 includes a through hole 201a opened on its side wall, and a slide groove 201b arranged on the bottom wall of the support frame 201; the screw member 202 passes through the through hole 201a and extends to the inside of the support frame 201; the second sliding member 203 is threadedly matched with the screw member 202, and the bottom of the second sliding member 203 is provided with a slider 203a adapted to the slide groove 201b.

[0059] It should be noted that the through hole 201a passes through the side wall of the support frame 201, and the axis of the through hole 201a is parallel to the tangent direction of the gear member 204; the screw member 202 passes through the through hole 201a and extends into the interior thereof, and the screw member 202 rotates along the axis direction of the through hole 201a.

[0060] Specifically, the second sliding member 203 is provided with an internal thread structure that is compatible with the screw member 202; the slider 203a is slidably connected to the slide groove 201b; the slider 203a moves inside the slide groove 201b, so that the rotation of the screw member 202 can drive the second sliding member 203 to reciprocate along the axial direction of the through hole 201a.

[0061] Preferably, the sliding block 203 a is disposed on the bottom surface of the second sliding member 203 , and the second sliding member 203 abuts against the bottom of the inner wall of the guide member 101 .

[0062] Furthermore, the second sliding member 203 is meshed with the gear member 204 , and the gear member 204 is located inside the support frame 201 ; the horizontal displacement of the second sliding member 203 is converted into the angular displacement of the gear member 204 .

[0063] In this embodiment, the second sliding member 203 is meshed with the gear member 204 , and the transmission between the second sliding member 203 and the gear member 204 can refer to the movement mode of the rack driving the gear.

[0064] Specifically, the second sliding member 203 moves along the axial direction of the screw member 202, and the teeth set on one side thereof mesh with the teeth of the gear member 204. During the movement, the teeth of the second sliding member 203 conflict with the teeth of the gear member 204, and can push the gear member 204 to rotate along the axial direction of the support frame 201, thereby realizing motion transmission.

[0065] Furthermore, the gear member 204 meshes with the first sliding member 102 , and the angular displacement of the gear member 204 is converted into the horizontal displacement of the first sliding member 102 ; the pushing block 103 is a trapezoidal structure, and the contact surface M1 of the pushing block 103 can contact the bottom of the lifting rod 104 .

[0066] In this embodiment, the gear member 204 is meshed with the first sliding member 102, and the rotation of the gear member 204 can drive the first sliding member 102 to move in the horizontal direction; the first sliding member 102 can drive the pushing block 103 to move while moving, and the resistance surface M1 of the pushing block 103 is an inclined end surface. As the resistance surface M1 of the pushing block 103 continuously approaches the bottom of the extruded lifting rod 104, the lifting rod 104 can move along a distance perpendicular to the pushing block 103; and then the top of the lifting rod 104 can penetrate the top side wall of the support frame 201 and extend to its outside.

[0067] It should be noted that there are multiple groups of first sliding members 102, and the multiple groups of first sliding members 102 are respectively meshed with the gear member 204, and the gear member 204 can drive the multiple groups of first sliding members 102 to move at the same time; the number of lifting rods 104 corresponds to the first sliding members 102, and when the multiple groups of first sliding members 102 move, they can synchronously drive the lifting rods 104 to move.

[0068] Furthermore, there are multiple groups of through holes 201a, which are distributed in a circular array along the side wall of the support frame 201; the guide member 101 is adapted to the through holes 201a, and the guide member 101 passes through the through holes 201a and extends to the inner side of the support frame 201; the first sliding member 102 can move along the axial direction of the guide member 101.

[0069] It should be noted that the number of through holes 201a corresponds to the total number of guide members 101 and screw members 202, and multiple groups of through holes 201a are distributed at equal angles along the cylindrical side wall of the support frame 201; the guide member 101 passes through the through holes 201a and extends to the inner side of the support frame 201; the guide member 101 can ensure that the first sliding member 102 can also move along the axial direction of the guide member 101 during the movement process.

[0070] Furthermore, the support frame 201 also includes a positioning column 201c on its surface, and a cavity 201c-1 is opened inside the positioning column 201c; the lifting rod 104 is passed through the interior of the positioning column 201c; the lifting rod 104 also includes a limit plate 104a arranged on its side wall; the limit plate 104a is located in the cavity 201c-1 and moves; the lifting rod 104 passes through the top side wall of the support frame 201, and both ends of the lifting rod 104 can extend out of the side wall of the support frame 201.

[0071] It should be noted that the number of positioning columns 201c corresponds to the number of lifting rods 104; a cavity 201c-1 is opened inside the positioning column 201c so that the lifting rod 104 can be located inside the cavity 201c-1; and the limiting plate 104a is movable inside the cavity 201c-1.

[0072] Specifically, the diameter of the limit plate 104a is larger than the diameter of the lifting rod 104. By setting the limit plate 104a to be movable inside the cavity 201c-1, it can be ensured that the lifting rod 104 will not be separated from the inside of the positioning column 201c during the movement; when the lifting rod 104 moves along the axial direction of the positioning column 201c, both ends of it can penetrate the top side wall of the support frame 201 and extend outward.

[0073] Furthermore, the rolling element 105 includes a fixing sleeve 105a and a ball 105b disposed inside the end of the fixing sleeve 105a; the ball 105b is located inside the fixing sleeve 105a and rolls; the fixing sleeve 105a coincides with the axis of the support frame 201.

[0074] In this embodiment, the fixing sleeve 105a is a circular ring structure, an annular slide is opened at the end position of the fixing sleeve 105a, and a rolling ball 105b is arranged inside the slide groove. The fixing sleeve 105a is arranged on the surface of the support frame 201, and the axis of the fixing sleeve 105a coincides with the support frame 201.

[0075] Furthermore, the axis of the support platform 106 coincides with that of the support frame 201 , and the first contact surface W1 of the support platform 106 can contact the surface of the support frame 201 ; the ball 105b contacts the second contact surface W2 of the support platform 106 , thereby achieving synchronous movement of the support platform 106 with the rolling element 105 .

[0076] In this embodiment, the support platform 106 includes a cylinder at the bottom and a platform at the top. The cylinder at the bottom of the support platform 106 is compatible with the support frame 201, so that the support platform 106 can move along the axial direction of the support frame 201.

[0077] Specifically, a reducer is placed above the normal support platform 106. Under its own weight, the reducer allows the first contact surface W1 of the support platform 106 to come into contact with the surface of the support frame 201. At this time, the friction between the support platform 106 and the support frame 201 is relatively large, making it more difficult for the support platform 106 to rotate.

[0078] When the rolling element 105 moves toward the support platform 106, the ball 105b continuously approaches the second contact surface W2 of the support platform 106 and collides with it, and then the rolling element 105 moves synchronously with the support platform 106; the rolling element 105 can drive the support platform 106 to move, so that there is a certain gap between the first contact surface W1 of the support platform 106 and the support frame 201; the rolling friction between the rolling element 105 and the support platform 106 can be used to drive the support platform 106 to rotate more effortlessly.

[0079] When in use, the staff places the reducer above the support platform 106, and the reducer penetrates the support platform 106 and extends to its outside; when it is necessary to adjust the position of the support platform 106, the screw member 202 is driven to rotate by a tool, and the rotation of the screw member 202 can drive the gear member 204 to rotate along the axial direction of the support frame 201. The rotation of the gear member 204 can drive multiple groups of first sliding members 102 to move, so that the first sliding member 102 drives the push block 103 set at its end to move, and the resistance surface M1 of the push block 103 continuously contacts the top during the horizontal movement. The bottom of the lifting rod 104 pushes the lifting rod 104 to move along the axial direction of the positioning column 201c. The movement of the lifting rod 104 can drive the rolling element 105 to move along the vertical direction. As the rolling element 105 continues to move, the ball 105b can conflict with the second contact surface W2 of the support platform 106; the rolling element 105 drives the support platform 106 to move along the vertical direction during the movement, so that there is a certain gap between the first contact surface W1 of the support platform 106 and the support frame 201, and at this time, the support platform 106 can be rotated more effortlessly to adjust the position of the reducer.

[0080] Example 3

[0081] Reference Figures 1 to 6 , which is the third embodiment of the present invention, is different from the other embodiments in that, including, a pushing block 103 is provided at the end of the second sliding member 203, and the pushing block 103 and the second sliding member 203 are fixed by bolt connection; the second sliding member 203 is similar in structure to the first sliding member 102, except that the second sliding member 203 has an internal thread structure, while the first sliding member 102 has a smooth through hole structure.

[0082] In this embodiment, the number of the through holes 201 a is three groups, one group of through holes 201 a is matched with the screw member 202 , and the other two groups of through holes 201 a are matched with the guide members 101 respectively.

[0083] It should be noted that the gear member 204 is respectively meshed with a group of second sliding members 203 and two groups of screw members 202. When the gear member 204 rotates, it can synchronously drive the second sliding member 203 and the screw member 202 to rotate. Since the number of screw members 202 is small, the load driven by the gear member 204 is small, resulting in a smaller force for rotating the screw member 202, and the gear 204 can be driven to rotate more easily.

[0084] Specifically, the ends of the second sliding member 203 and the first sliding member 102 are both provided with pushing blocks 103; and the three groups of pushing blocks 103 correspond to the three groups of lifting rods 104; the three groups of lifting rods 104 move synchronously along the vertical direction, and the three groups of lifting rods 104 are distributed at equal angles along the axis of the guide member 101; the synchronous movement of the three groups of lifting rods 104 can steadily push the rolling member 105 to move along the vertical direction.

[0085] While the rolling element 105 is moving, it can lift the supporting platform 106 to a certain distance, so that the first contact surface W1 of the supporting platform 106 is separated from the surface of the supporting frame 201; thus, the supporting platform 106 can be pushed to rotate more easily.

[0086] Example 4

[0087] This is the fourth embodiment of the present invention, which further provides a method for using a motor reducer maintenance tool, including: S1: placing the reducer above the support platform 106, and using the support frame 201 to ensure that the reducer is at a certain distance from the bottom surface.

[0088] It should be noted that the staff uses a lifting device to place the reducer above the support platform 106. Under the effect of the reducer's own weight, the first contact surface W1 of the support platform 106 is in contact with the surface of the support frame 201. At this time, the reducer is a certain distance from the ground, which can better facilitate the inspection and maintenance of the reducer.

[0089] S2: Adjust the angle position of the reducer, and drive the top of the lifting rod 104 to extend out of the side wall of the support frame 201 by rotating the screw rod 202. When the lifting rod 104 moves, it pushes the top of the rolling element 105 to contact the second contact surface W2 of the support platform 106. As the lifting rod 104 continues to extend, the first contact surface W1 of the support platform 106 is separated from the surface of the support frame 201.

[0090] It should be noted that when it is necessary to adjust the position of the reducer relative to the support frame 201, a tool can be used to drive the screw member 202 to rotate. When the screw member 202 rotates, it drives the second sliding member 203 to move along the axis of the screw member 202; when the second sliding member 203 moves, it can drive the gear member 204 to rotate along the axis of the support frame 201. When the gear member 204 rotates, it can drive the first sliding member 102 to move, so that the pushing block 103 set on the top of the first sliding member 102 moves in the horizontal direction. As the pushing block 103 moves, the lifting rod 104 can be pushed to move in the vertical direction, thereby driving the rolling member 105 to lift the support platform 106 to a certain distance, so that there is a certain gap between the first contact surface W1 of the support platform 106 and the surface of the support frame 201, which can make the support platform 106 rotate more labor-saving.

[0091] S3: The rolling element 105 contacts the second contact surface W2 of the support platform 106, and at this time, the support platform 106 is pushed to rotate along the axis of the support frame 201, thereby adjusting the angle of the reducer.

[0092] It should be noted that when there is a certain gap between the support platform 106 and the support frame 201, 105b contacts the second contact surface W2 of the support platform 106; the support platform 106 can save more effort during the rotation process, so that the support platform 106 can easily adjust the angle, and then the reducer located at the end of the support platform 106 can be rotated to a certain angle.
