Embodiment Construction

[0013] Next, an electric hoist as an example of the present invention will be described based on the drawings.

[0014] figure 1 It is a schematic front view showing the electric hoist of the present invention.

[0015] Such as figure 1 As shown, the electric hoist of the present invention includes a reducer 10 on one side, a lifting motor 20 on the other side, and a reel 30 located between the reducer 10 and the lifting motor 20 .

[0016] A rope guide 40 straddling the reel 20 is erected on the housing of the speed reducer 10 and the housing of the lifting motor 20 . The rope guide 40 includes a connecting shaft 41 and a guiding disc 42 slidingly connected with the connecting shaft 41 .

[0017] The two ends of the connecting shaft 41 are respectively connected with the housing of the speed reducer 10 and the housing of the lifting motor 20, and the middle part of the guide rope disc 42 has a through connection hole for sliding connection with the connecting shaft 41, and ...

Abstract

The invention provides an electric hoist which can prevent a rope from being disengaged from a rope groove. The electric hoist comprises a speed reducer located on one side, a lifting motor located on the other side, and a winding drum located between the speed reducer and the lifting motor. A rope guiding device stretching across the winding drum is erected on a shell of the speed reducer and a shell of the lifting motor. The rope guiding device comprises a connecting shaft and a rope guiding disc connected with the connecting shaft in a sliding mode. The two ends of the connecting shaft are connected with the shell of the speed reducer and the shell of the lifting motor respectively. A through connecting hole used for being in sliding connection with the connecting shaft is formed in the center of the rope guiding disc. The periphery of the rope guiding disc is composed of an arc flange formed along the circumferential surface of the rope guiding disc and an arc groove connected with the arc flange and formed along the circumferential surface of the rope guiding disc. The arc flange can be embedded in the rope groove of the winding drum. The arc groove can be matched with the rope groove of the winding drum, so that the rope wound on the winding drum is surrounded.

Description

technical field [0001] The invention relates to an electric hoist. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is mainly composed of motor, transmission mechanism and reel, etc. It is usually installed on the crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and convenient use. In industrial and mining enterprises, storage terminals and other places. [0003] When using an electric hoist, the motor drives the reel to rotate, so that the rope wound on the rope groove of the reel is retracted to lift or release the object suspended by the rope. But for such an electric hoist, when retracting and retracting the rope, the rope may break away from the rope groove. If the rope leaves the rope groove, when continuing to retract and retract, the shell of the electric hoist may block the rope. At this time, the entire electric hoist will vibrate, affecting Lifting safety, but a...
