Description

Protective electric hoist

Technical Field

The utility model relates to the technical field of electric hoists, in particular to a protective electric hoist.

Background

As is well known, the electric hoist is a special lifting device which is arranged on the crown block and the gantry crane and has the characteristics of small volume, light dead weight, simple operation, convenient use and the like. However, when the existing electric hoist does not have a protection device and is used for lifting an object, if the object is unhooked or a rope for binding the object is broken, the lifting hook losing the weight can be sprung upwards by inertia, and the sprung lifting hook can directly strike on the electric hoist main body, so that the electric hoist main body is damaged.

Further, the traction rope is a steel wire rope.

Further, the traction rope penetrates through the baffle plate from the through groove.

Further, the connecting shaft penetrates through the baffle plate from the mounting hole, and the connecting shaft is in sliding connection with the baffle plate.

Further, the diameter between the anti-drop blocks is larger than the diameter of the mounting hole.

Further, be provided with the several button on the controller, controller and electric block main part pass through cable electric connection.

(III) beneficial effects

Compared with the prior art, the utility model provides a protective electric hoist, which has the following beneficial effects:

this protection type electric hoist, through the setting of connecting axle, baffle and spring, when the rope fracture of article unhook or binding article, the lifting hook that loses the heavy object can be sprung up by inertia, and the lifting hook striking is on the baffle, and the baffle is effectual has prevented that the lifting hook from directly striking on electric hoist, and the spring can effectively cushion the impact of lifting hook, plays the guard action to electric hoist, effectively prevents that the lifting hook that pops up from bumping bad electric hoist.
