Compared with the prior art, this solution fixes the rotating shaft of the motor and the first horizontal channel steel to each other through the first fixing mechanism, so as to fix the protection plate to the rotating shaft, and at the same time, the second fixing mechanism fixes the first channel steel and the second channel steel to the bearing outer cover of the motor, so as to fix the protection plate to the motor, the first fixing mechanism and the second fixing mechanism cooperate to realize that the protection plate restricts the rotating shaft, effectively preventing the axial movement and self-rotation of the rotating shaft, and ensuring that the rotating shaft of the motor is restricted stably and reliably during transportation.

[0005] In order to better fix the protection plate to the bearing outer cover of the motor, in some preferred embodiments, the upper and lower ends of the first channel steel are both provided with second channel steels, and the second channel steels at the upper and lower ends of the first channel steel are arranged opposite to each other. The second channel steels arranged opposite to each other at the upper and lower ends ensure the stability of the center of gravity of the protection plate itself, and better fix the protection plate to the bearing outer cover of the motor.

[0006] In order to ensure the connection strength of the protection plate, in some preferred embodiments, the notch of the first channel steel and the notch of the second channel steel are arranged in the same direction. The notches of the first channel steel and the second channel steel are arranged in the same direction to ensure the connection strength of the first channel steel and the second channel steel, and at the same time ensure the overall strength of the protection plate.

[0007] In order to realize the first fixing mechanism, some preferred embodiments are that the first fixing mechanism includes a fixing screw, a first mounting hole is formed on the first channel steel, one end of the fixing screw passes through the first mounting hole and is threadedly connected to the rotating shaft of the motor, and the fixing screw is eccentrically arranged with the rotating shaft.

[0008] In order to prevent the problem of loosening of the fixing screws and causing the failure of the rotation axis restriction, in some preferred embodiments, there are multiple fixing screws, and the multiple fixing screws are arranged along the circumferential direction of the axis of the rotation axis. If multiple fixing screws are arranged along the circumference, even if one fixing screw is loose, it will not cause the failure of the rotation axis restriction.

[0009] In order to realize the second fixing mechanism, some embodiments are preferred, wherein the second fixing mechanism includes a connecting screw, one end of which is fixedly connected to the corresponding first channel steel or second channel steel, and the other end of which is screwed to the bearing outer cover of the motor. By fixing one end of the connecting screw to the first channel steel and the second channel steel, and the other end of the connecting screw to the bearing outer cover, the second fixing mechanism is realized to fix the protective plate and the bearing outer cover of the motor to each other.

[0012] If the positioning sleeve is too short, the positioning of the protection plate will be unstable, which is not convenient for the installation of the protection plate. Preferably, in some embodiments, the length of the positioning sleeve is 50mm-70mm. Setting the length of the positioning sleeve to 50mm-70mm increases the axial length of the positioning sleeve, and directly places the protection plate on the rotating shaft, which is convenient for the installation of the protection plate.

[0013] In order to avoid the problem of interference between the length of the positioning sleeve and the key on the rotating shaft due to the increase in the length of the positioning sleeve, in some preferred embodiments, an avoidance groove is provided on the inner circumferential wall of the positioning sleeve, and the width of the avoidance groove is greater than the width of the key on the rotating shaft. An avoidance groove corresponding to the rotating shaft is provided on the inner circumferential wall of the positioning sleeve, and the width of the avoidance groove is greater than the width of the key, so that the positioning sleeve can be placed on the rotating shaft.

[0014] The beneficial effect of the utility model is that when the shaft extension protection support plate of the utility model is in use, the rotating shaft of the motor and the first horizontal channel steel are fixed to each other through the first fixing mechanism, and the bearing outer cover of the motor is fixed, so that the protection plate and the motor are fixed, and at the same time the second fixing mechanism fixes the first channel steel and the second channel steel to the bearing outer cover of the motor, effectively preventing the axial movement and rotation of the rotating shaft, ensuring that the rotating shaft of the motor is restricted stably and reliably during transportation, and avoiding the problem that the inertia of the existing motor during transportation will cause the rotating shaft of the motor to move axially or rotate, thereby causing damage to the bearings and other components on the rotating shaft.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] like Figure 1-6 As shown, a shaft extension protection support plate includes a protection plate 1, and the protection plate 1 includes a first channel steel 2 and a second channel steel 3. The first channel steel 2 is arranged in the transverse direction, and the second channel steel 3 is arranged in the longitudinal direction and fixedly connected to the upper end of the first channel steel 2. The second channel steel 3 is arranged at both ends of the first channel steel 2, and the second channel steels 3 at both ends of the first channel steel 2 are arranged relatively. A first fixing mechanism is arranged on the first channel steel 2, and the first fixing mechanism is used to be fixedly connected to the rotating shaft 9 on the motor. The first channel steel 2 and the second channel steel 3 are arranged on the second fixing mechanism, and the second fixing mechanism is used to be fixedly connected to the bearing outer cover 12 of the motor 11.

[0028] In this embodiment, since the channel steel is available and can be purchased directly, and the channel steel itself has high strength, the first channel steel 2 is arranged horizontally, and the second channel steel 3 is arranged longitudinally at the upper and lower ends of the first channel steel 2, the notch of the first channel steel 2 and the notch of the second channel steel 3 are arranged in the same direction, and the first channel steel 2 and the second channel steel 3 are welded together, which improves the strength of the protection plate 1 and ensures that the protection plate 1 is stable and reliable in use.

[0029] The first fixing mechanism includes a fixing screw 4. Three first mounting holes are opened on the first channel steel 2. One end of the three fixing screws 4 passes through the corresponding first mounting holes respectively and is threadedly connected to the rotating shaft 9 of the motor 11. The three fixing screws 4 are all eccentrically arranged with respect to the rotating shaft 9. The three fixing screws 4 are arranged along the circumferential direction of the axis of the rotating shaft 9.

[0030] The second fixing mechanism includes a connecting screw 5, the other end of which is screwed to the bearing outer cover 12 of the motor 11, and the first channel steel 2 and the second channel steel 3 are both provided with a second mounting hole 6, one end of the connecting screw 5 passes through the second mounting hole 6 and is threadedly connected to the nut, so that one end of the connecting screw 5 is fixedly connected to the corresponding first channel steel 2 or second channel steel 3, and the two ends of the first channel steel 2 are fixedly connected with the connecting screw 5, and the second channel steel 3 at the upper and lower ends are also fixedly connected with the connecting screw 5.

The rotating shaft 9 is arranged in the positioning sleeve 7. In this embodiment, the length of the positioning sleeve 7 is preferably 60 mm, but it can also be 50 mm or 70 mm.

[0032] Since the positioning sleeve 7 is too long, it will interfere with the key. If the keyway and the key are processed, the keyway processing accuracy is high, which will increase the cost. Therefore, an avoidance groove 8 is opened on the inner wall of the positioning sleeve 7. The width of the avoidance groove 8 is greater than the width of the key on the rotating shaft 9. There is no requirement for the accuracy of the avoidance groove 8. The single side is 0.5mm wider than the key width, which meets the installation requirements of the positioning sleeve 7.

[0033] When assembling the shaft extension protection support plate, firstly, one end of the connecting screw 5 is threadedly connected to the bearing outer cover 12 of the motor 11, and then the positioning sleeve 7 is aligned with the rotating shaft 9, and the key on the rotating shaft 9 is aligned with the avoidance groove 8, and then the positioning sleeve 7 is sleeved on the rotating shaft 9, and at the same time, the other end of the connecting screw 5 is aligned and passed through the second mounting hole 6, and then three fixing screws 4 are sequentially passed through the first mounting hole and threadedly connected to the rotating shaft 9, and the first fixing mechanism is implemented to fix the protection plate 1 with the rotating shaft 9, and then the nut is threadedly connected to the connecting screw 5, and the second fixing mechanism is implemented to fix the protection plate 1 with the bearing outer cover 12 of the motor 11, and the installation of the protection plate 1 is completed;
