Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying 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 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 provided below the mounting ring 21.

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

[0040] And when the chain bag 2 works, the chain can be automatically stored in the chain bag 2, which can prevent the chain from being st...

Abstract

The invention discloses an electric hoist, which relates to the field of electric hoists, comprising an electric hoist body and a chain bag, the chain bag includes a mounting ring, a pair of support frames are arranged side by side on the upper end surface of the mounting ring, and a bag body is arranged below the mounting ring; The upper end surface of the bag body is provided with a plurality of installation blocks evenly at intervals, the lower end surface of the installation ring is provided with installation grooves for the installation blocks to be embedded in, and the installation ring is provided with a locking mechanism for fixing the installation blocks. The present invention has the following advantages and effects: by setting the modularized chain bag, the bag body can be disassembled and individually maintained and replaced without replacing the entire chain bag, which reduces maintenance costs and waste of resources.

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, 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] 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. An electric hoist body is connected with a hook to form a double electric hoist as a whole. [0004] The above-mentioned chain bag of the electric hoist is fixed on the body of the electric hoist by bolts, but when the chain bag is damaged, the entire chain bag needs to be replaced, which not only increases the cost, but also caus...
