Embodiment 1

[0029] Embodiment 1, the present invention is mainly used to improve the fall prevention of the electric hoist. While improving the fall prevention, the driving mode of the electric hoist is also changed, but the first motor 4 is still the existing conical motor. The structure can still realize the function of starting and stopping the electric hoist and automatically locking the brake after stopping.

[0030] The present invention includes a beam 1, a slide rail 2, a housing 3, and an electric hoist device. The beam 1 can make the electric hoist move on it, and the specific movement is realized by the slide rail 2. The electric hoist device is the core device, both It includes the driving device of the electric hoist, and also includes the anti-falling device of the electric hoist. The shell 3 can move on the slide rail 2 as the shell, and the electric hoist is fixed in the shell 3. The driving force in the electric hoist is the first Motor 4, the first motor 4 is an existing...

Embodiment 2

[0032] Embodiment 2, on the basis of Embodiment 1, when the first friction cone wheel 6 is connected to the first drive shaft 5, the first bearing seat 36 is used on the shaft, and the cross section is connected by a key 37 .

Embodiment 3

[0033] Embodiment three, on the basis of embodiment one, the front end and the middle of the second friction cone wheel 7 described above are because the second friction cone wheel 7 is designed to be integrally connected and stepped, and the second friction cone wheel 7 does not It may also be stepped.

Abstract

The invention relates to a fallproof safety device for an electric hoist. The device efficiently solves the problem that an electric hoist falls when the electric hoist is overweight. According to the technical scheme of solving the problem, the electric hoist includes a first electric motor that is connected with a first friction bevel pulley that is matched with a second friction bevel pulley that is inserted with a second driving rotating shaft, a first spring is arranged in the second friction bevel pulley and positioned at the front end of the second friction bevel pulley, the middle wall of the second friction bevel pulley is connected with the second driving rotation shaft in a screw joint mode; a first rotation shaft is fixed on a mounting plate and provided with a cross-shaped rotation plate that can rotate around the first rotation shaft, the left portion of the cross-shaped rotation plate is arranged with a reel in a sleeved mode and the reel is wound with steel wire rope.

Description

technical field [0001] The invention relates to the technical field of electric hoists, in particular to an anti-falling safety device for electric hoists. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places. [0003] The wire rope electric hoist is a small lifting equipment. The wire rope electric hoist has the advantages of compact structure, light weight, small volume, strong versatility of parts, and convenient operation. It can be installed on the I-beam alone or as a set Used on electric or manual single-girder, double-girder, cantilever, gantry and other cranes. The motor generally uses a conical motor, which automatically locks the brake after stopping, and the matching steel wire ropes include pho...
