Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a motor and a reducer installation tool. Background Art

[0002] In the rotary assembly, the weight of the motor generally exceeds 100 kilograms, and the reducer exceeds 300 kilograms. It is difficult to lift and install them by manpower alone, so lifting equipment and lifting tools must be used for installation. The space inside the rotary assembly is generally small. When installing and removing the reducer and motor in a small space, if the lifting tools are welded on the outside of the reducer and motor, the activity space will inevitably be further reduced, resulting in installation difficulties, or even inability to complete the installation work. In addition, the reducer adopts a stepped shaft structure and the shaft end is short, making it difficult to weld the lifting tools.

[0003] The installation tool structure of motors and reducers of conventional products on the market currently utilizes the threaded holes on the motor base and the original threaded holes on the reducer, and uses detachable hanging nails to directly connect the reducer and the motor. After the hanging nails are tightened, the hanging nails are connected with hooks, and the lifting movement of the reducer and the motor is realized through the lifting device, thereby completing the installation and fixation of the reducer and the motor, and the hanging nails are removed after installation.

[0004] However, as the scope of application expands, reducers and motors are used upside down. If the existing motor and reducer installation tools are used in reverse rotation, it is difficult to install the reducer and the motor. When installing the motor, the existing technology on the market is that the distance between the two hanging nails installed on the motor is smaller than the size of the reducer installation mechanism. When lifting, the distance between the slings must be smaller than the reducer installation mechanism, and interference will occur between the slings and the reducer installation mechanism, making it impossible to complete the motor installation operation. Utility Model Content

[0005] The purpose of the utility model is to provide a motor and reducer installation tool to solve the problem that when the prior art is used in an inverted manner as mentioned in the above background technology, when installing the motor, the distance between the two hanging nails installed on the motor is smaller than the size of the reducer installation mechanism. When lifting, the distance between the slings must be smaller than the reducer installation mechanism, and interference will occur between the slings and the reducer installation mechanism, making it impossible to complete the installation operation of the motor.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a motor and reducer installation tool, comprising:

[0007] A reducer auxiliary tool, the reducer auxiliary tool comprising a fixed base plate fixed on the reducer and a lifting lug for a lifting device hook, wherein the fixed base plate is adapted to the shape of the contact portion with the reducer;

[0008] A motor auxiliary tool, the motor auxiliary tool comprising a connecting portion connected to the motor and a lifting lug for connecting to a lifting device hook;

[0009] Wherein, the inner distance between the motor auxiliary tool and the reducer auxiliary tool after the installation hook is greater than the size of the reducer installation mechanism.

[0010] Preferably, the fixed base plate is connected to the screw holes on the reducer by bolts penetrating through the openings on the fixed base plate.

[0011] Preferably, at least two groups of the lifting ears are arranged on the fixed base plate and are fixed to each other.

[0012] Preferably, a rib plate for increasing strength is provided between the fixed base plate and the lifting ear.

[0013] Preferably, a vertical plate for enhancing strength is fixed on the fixed bottom plate.

[0014] Preferably, the connecting part includes one or several groups of ear plates connected to the motor and a supporting base plate integral with the ear plates, the supporting base plate is adapted to the shape of the corresponding surface of the motor, the ear plates are connected to the screw holes on the motor by bolts passing through the openings therein, and the ears are arranged in at least two groups on the supporting base plate.

[0015] Preferably, a rib plate for increasing strength is provided between the ear plate and the supporting base plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] Compared with the existing tool structure design, the utility model can be installed in different directions by replacing the contact surface between the tool and the motor and the reducer. The inner distance after the motor auxiliary tool and the reducer auxiliary tool are installed on the hook is greater than the size of the reducer installation mechanism. During installation, it is not only suitable for the forward installation of the motor and the reducer, but also suitable for reverse installation. At the same time, by adjusting the distance between the lifting ears and the size of the components, interference with other parts in the rotating assembly can be avoided. It is suitable for the installation and subsequent maintenance of motors and reducers in various rotating assemblies with complex structures, and solves the problem in the prior art that the distance between the two hanging nails installed on the motor is smaller than the size of the reducer installation mechanism. During lifting, the distance between the slings must be smaller than the reducer installation mechanism, and interference will occur between the slings and the reducer installation mechanism, making it impossible to complete the installation of the motor.

[0025] The following will be combined with the drawings in 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 in 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.

[0026] See also Figure 1-Figure 3 As shown in the figure, the installation tool structure type of the motor and reducer of the conventional products on the market currently utilizes the threaded holes on the motor base and the original threaded holes on the reducer, and uses detachable hanging nails to directly connect with the reducer and the motor. After the hanging nails are tightened, the hanging nails are connected with hooks, and the lifting movement of the reducer and the motor is realized through the lifting device, thereby completing the installation and fixation of the reducer and the motor, and the hanging nails are removed after installation.

[0027] See also Figure 4-Figure 6 The utility model provides a motor and reducer installation tool, which is composed of a reducer auxiliary tool 1 installed on the reducer and a motor auxiliary tool 2 installed on the motor;

[0028] It should be noted that: Figure 4 As shown, in order to adapt to the inverted use of the reducer and the motor, the inner distance between the motor auxiliary tool 2 and the reducer auxiliary tool 1 after the installation hook is greater than the size of the reducer installation mechanism, so as to solve the interference problem during inverted installation. In this way, the position of the lifting ear 4 on the motor auxiliary tool 2 can be wider than the position of the lifting ear 4 on the reducer auxiliary tool 1, so as to prevent the following Figure 3In the prior art, when installing the motor, the distance between the two hanging nails installed on the motor is smaller than the size of the reducer installation mechanism. When lifting, the distance between the slings must be smaller than the reducer installation mechanism, and interference will occur between the slings and the reducer installation mechanism, making it impossible to complete the installation of the motor.

[0029] In specific implementation, Figure 5 As shown, the reducer auxiliary tool 1 includes a fixed base plate 101 fixed on the reducer and a lifting ear 4 for connecting the hook of the lifting device, and the shape of the fixed base plate 101 and the reducer are adapted; the fixed base plate 101 is fan-shaped, but not limited to the above shape. Technical personnel in this field can make appropriate settings and selections according to actual needs and according to the reducer model, and connect it to the screw holes on the reducer by passing bolts through the openings on the fixed base plate 101.

[0030] The lifting ears 4 are arranged in parallel and symmetrically at the two ends of the fixed base plate 101 and are fixed to the fixed base plate 101, so that the two lifting points are at the relative quadrature points of the reducer during the lifting process, making the lifting more stable. For the specific number and arrangement, technical personnel in this field can make appropriate settings according to actual needs, including but not limited to the above-mentioned limitations.

[0031] As an improvement, a rib plate 3 for increasing strength is provided between the fixed base plate 101 and the lifting lug 4. Since the actual weight of the reducer is about 100 to 200 kilograms, the strength of the overall structure can be increased through this structure to ensure the stability of the installation.

[0032] A vertical plate 102 is fixed on the fixed bottom plate 101 to enhance the overall strength together with the rib plate 3 .

[0033] like Figure 6 As shown, the motor auxiliary tool 2 includes a connection portion connected to the motor and a lifting lug 4 for a lifting device hook;

[0034] In a specific implementation, the connecting portion includes one or several groups of ear plates 201 connected to the motor and a fan-shaped supporting base plate 202 integral with the ear plates 201. The supporting base plate 202 is adapted to the shape of the corresponding surface of the motor, but is not limited to the above shape. Technical personnel in this field can make appropriate settings and selections according to actual needs and according to the motor model. The ear plate 201 is connected to the screw hole on the motor by bolts passing through the openings therein, and the lifting ears 4 are arranged parallel and symmetrically at both ends of the supporting base plate 202.

[0035] As an advanced improvement, a rib plate 3 is provided between the ear plate 201 and the supporting base plate 202 to enhance strength.

[0036] It should be noted that: in this embodiment, a group of ear plates 201 are arranged in parallel at both ends of the supporting base plate 202. However, the number of groups is not limited to the above, and the holes through which the bolts on the ear plates 201 pass can be set by those skilled in the art according to the model of the screw holes on the actual motor, and the number of groups is selected and set according to the number of screw holes on the motor, so as to achieve installation without modifying the existing motor.

[0037] In actual use, first determine the lifting direction of the motor or reducer, and install the reducer auxiliary tool 1 installed on the reducer and the motor auxiliary tool 2 installed on the motor with the lifting lug 4 facing the lifting direction, so as to ensure that the connection direction between the lifting lug 4 and the hook is correct and the force can be correctly transmitted. Lift the reducer and the motor in turn through the lifting equipment. After the installation is completed, remove the reducer auxiliary tool 1 and / or the motor auxiliary tool 2 to complete the installation work.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
