Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: due to the harsh environment of the mine, there is a lot of dust, the dust is easy to adhere to the chain rings, and is brought into the interior of the electric chain hoist by the transmission chain, and the dust is easy to accumulate inside the chain hoist. Entering the rotation gap of the second rotating shaft, hindering its rotation, making it unstable and affecting the normal operation of the hoist. In addition, the inorganic salt in the dust will accelerate the corrosion of the chain link

Abstract

The invention discloses an electric hoist for a mine, and relates to the technical field of hoisting devices. According to the main points of the technical scheme, the hoist comprises a shell, a driving motor, a reduction gear set, a chain wheel, a chain ring, a lifting hook and a chain ring bag; the shell is provided with an air supply cavity, an air channel and a first one-way valve; a high-pressure airflow generating device is arranged in the air supply cavity, and the high-pressure airflow generating device comprises a cam, a push plate, a second one-way valve and a pressure limiting valve, wherein the cam is provided with a sliding block, and the push plate is provided with a push rod; the shell is provided with a pulse valve; the air channel comprises a main channel and a branch channel; the shell is provided with a filtering cover; the shell is provided with a buffering air bag and a communicating pipeline, wherein the buffering air bag is provided with an air blowing pipe and an air gun; and the shell is provided with a waxing device. According to the hoist, the high-pressure airflow generating device and the pulse valve are arranged, so that dust is not prone to entering the electric hoist; the buffering air bag is arranged, so that the electric hoist is not prone to be impacted and damaged; and the waxing device is arranged, so that the surface of the chain ring is not prone to rusting, and dust is not prone to adhering to the surface of the chain ring.

Description

technical field [0001] The invention relates to the technical field of lifting devices, in particular to an electric hoist for mines. 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. Electric hoists are mainly divided into: chain electric hoist, wire rope electric hoist, anti-corrosion electric hoist, double-drum electric hoist, hoist, miniature electric hoist, group crane electric hoist, multi-function hoist. [0003] The Chinese invention patent with the existing application publication number CN110902592A discloses an electric chain hoist, including a box body, a partition, a second speed reduction wheel, a mounting through hole, an internal threaded pipe, a second rotating shaft, and a motor fixed o...
