Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the drawings.

[0038] Such as figure 1 , figure 2 As shown, an electric hoist includes an electric hoist body 1 and a chain bag 2. The chain bag 2 includes a mounting ring 21, a pair of support frames 22 are arranged side by side on the upper end surface of the mounting ring 21, the upper ends of the support frames 22 are fixedly connected to the electric hoist body 1 by bolts, and a bag body 23 is arranged under the mounting ring 21.

[0039] When installing the chain bag 2, a pair of support frames 22 are first fixed to the electric hoist body 1 with bolts to realize the installation and fixation of the installation ring 21. Then, the bag body 23 is fixed on the installation ring 21 to realize the installation and fixation of the chain bag 2.

[0040] And when the chain bag 2 is working, the chain can be automatically stored in the chain bag 2, which can prevent the chain from jamming or a...

Abstract

The invention discloses an electric hoist, and relates to the field of electric hoists. The electric hoist comprises an electric hoist body and a chain bag, wherein the chain bag comprises a mountingring; a pair of support frames are arranged side by side on the upper end surface of the mounting ring; a bag body is arranged below the mounting ring; a plurality of installation blocks are evenly arranged on the upper end of the bag body at intervals; mounting grooves for embedding of the installation blocks are formed in the lower end surface of the mounting ring; and locking mechanisms for fixing the installation blocks are arranged on the mounting ring. The electric hoist has the following advantages and effects that the separate disassembly and separate maintenance and replacement of thebag body are realized by arranging the modular chain bag, the whole chain bag does not need to be replaced, the maintenance cost is reduced, and the wasting of resources is also reduced.

Description

Technical field [0001] The invention relates to the field of electric hoists, in particular to an electric hoist. Background technique [0002] Electric hoist is a kind of special lifting equipment, installed on overhead cranes and gantry cranes. 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] Chinese patent CN204661217U discloses a double electric hoist, which includes an electric hoist body and an electric trolley. The two electric hoist bodies are installed in reverse and arranged in parallel. The chain bag is connected to the electric hoist body by bolts, and the chain in the chain bag bypasses the two The body of an electric hoist is connected with a hook to form a double electric hoist as a whole. [0004] The chain bag of the electric hoist described above is fixed on the electric hoist body by bolt connection, but when the ch...
