Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, to an electric drive unit. Background Technology

[0002] A monorail crane is an auxiliary transportation device that operates on a suspended monorail system, characterized by high mobility, high speed, large load capacity, compact structure, and stable and reliable operation. The monorail drive unit is primarily used for load bearing, driving, and braking of the monorail crane, and can operate on a single track ranging from a horizontal plane to an inclination angle of 30°. Traditionally, the drive units for monorail cranes were mostly hydraulically controlled, requiring high sealing standards and presenting significant manufacturing challenges. Currently, electric drives have replaced hydraulic drives for monorail cranes.

[0003] The drive wheels that travel in conjunction with the monorail are exposed to the elements for extended periods, and due to harsh external working conditions, the track and wheel surfaces are prone to becoming stained, resulting in uneven contact surfaces. This causes the monorail crane to experience bumpy travel and poor overall performance. Therefore, this invention proposes an electric drive unit. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an electric drive unit.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The electric drive unit involved in this utility model includes a frame, on which a bearing wheel is rotatably connected. The frame is also provided with a braking mechanism, a clamping mechanism, and a drive mechanism. The drive mechanism includes an electric motor with a motor main shaft with both ends extending outward. One end of the motor main shaft is provided with a follower drive wheel, and the other end is provided with a follower drive gear. The drive mechanism also includes an auxiliary shaft rotatably connected to the frame. One end of the auxiliary shaft is provided with a follower cleaning roller, and the other end is provided with a follower driven gear. The driven gear meshes with the drive gear, and the roller surface of the cleaning roller abuts against the drive wheel.

[0006] The present invention is further configured such that the drive mechanism is arranged symmetrically on the frame.

[0007] In summary, the present invention has the following beneficial effects: The electric drive unit involved in the present invention uses the same power mechanism to synchronously operate the drive wheel and the cleaning roller to rotate. The rotating drive wheel can drive the monorail crane to move, and the rotating cleaning roller can clean the surface of the drive wheel to prevent the surface of the wheel from getting dirty, so as to make the driving smooth. The overall function is perfect and the practicality is strong. Attached Figure Description

[0014] Furthermore, the drive mechanism is arranged symmetrically on the frame 1.

[0015] In this embodiment, the electric drive unit is installed on the monorail crane, providing it with the power to move. By operating the electric motor 3, the drive wheels 5 rotate via shaft transmission, causing the monorail crane to move. Simultaneously with the rotation of the motor's main shaft 4, the auxiliary shaft 7 and its cleaning rollers 8 also rotate synchronously via the drive gear 6 and driven gear 9, with the cleaning rollers 8 cleaning the surface of the drive wheels 5.
