[0029] Principle of the utility model

[0030] As shown in the drawings, Figure 1 , 2 When the Roots blower maintenance operation platform provided in the present application works normally, the upper end of the lifting platform 3 is flush with the upper surface of the workbench 1, the Roots blower to be maintained, parts and maintenance tools are placed on the lifting platform 3, and normal maintenance of the Roots blower by the workers can be facilitated; at the same time, the universal wheels 5 are located in the accommodating groove 4, and the stability of the entire workbench 1 can be ensured.

[0031] When the Roots blower needs to be tested for operation, as shown in the drawings, Figure 3 , 4 The motor 8 is started, the lifting platform 3 drives the Roots blower to move downward under the driving of the sliding block 9 and the connecting cylinder 10, so that the lifting platform 3, the blower, the parts and the maintenance tools are all located in the groove 2; when the Roots blower is started, the vibration generated by the operation of the blower will not cause the parts and the maintenance tools to be separated from the workbench 1.

[0032] When the lifting platform 3 moves downward, the wheel frame 6 and the universal wheel 5 also move downward under the drive of the connecting rod 12; when the workbench 1 does not need to be moved, only the distance that the lifting platform 3 moves needs to be controlled to ensure that the universal wheel 5 will not be released from the containing groove 4; when the entire workbench 1 needs to be moved, only the sliding block 9 needs to be continuously moved downward until the universal wheel 5 is released from the containing groove 4, at which time the universal wheel 5 replaces the bottom of the workbench 1 to contact the ground, facilitating the movement of the entire workbench 1.

[0033] As shown in Figure 4 When the lifting platform 3 needs to be rotated to change the orientation position of the fan on the lifting platform 3, the motor 8 is started again, the sliding block 9 and the connecting cylinder 10 drive the lifting platform 3 to move upward until the insertion rod 14 is separated from the limiting hole 13, at which time the rotation restriction of the lifting platform 3 is released, and the lifting platform 3 can be freely rotated relative to the connecting cylinder 10; when the lifting platform 3 is rotated to the appropriate position, the insertion rod 14 is aligned with the corresponding limiting hole 13, the motor 8 is reversed, the lifting platform 3 and the insertion rod 14 are driven to move downward until the insertion rod 14 is reinserted into the limiting hole 13 to restrict the rotation of the lifting platform 3, and at the same time, the upper end of the lifting platform 3 is flush with the upper surface of the workbench 1.

[0034] The above describes the present application and its embodiments, which are not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired by the above description, without departing from the creative purpose of the present application, similar structural modes and embodiments can be designed without creativity, which should belong to the protection scope of the present application.
