Handcart type electric chain hoist

Abstract

The invention discloses a handcart type electric chain hoist which comprises a box body, wherein a motor, a chain wheel, a chain and a transmission mechanism are arranged in the box body. The handcart type electric chain hoist is characterized in that the chain wheel is arranged in the middle of the box body; the motor is arranged on one side of the chain wheel, and a gearbox is arranged on the other side of the chain wheel; a fixator is arranged at the top of the box body, a monorail cart is connected to the fixator, and a buffer is arranged on the monorail cart. The monorail cart arranged at the top of the box body is used for of the moving of the electric hoist, and the buffer can control the buffer level of the electric hoist. A hand wheel connected to the monorail cart can control the moving of the monorail cart, and the hand chain wound on the hand wheel can be used for pulling the hand wheel,. Therefore, the monorail cart moves to drive the electric hoist to move. The handcart type electric chain hoist has the advantages of simple structure, convenience in use and low cost.

Description

technical field [0001] The invention relates to an electric hoist, in particular to an electric chain hoist with a trolley. 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. The electric hoist can lift heavy objects high or from one place to another, but during the lifting process, the objects move in space, and most electric hoists need to be hung on the beam, so a long rope is needed to pull the hoist. The hook moves up and down. Most of the existing electric hoists are pulled by steel ropes. The steel ropes are easy to expand and contract. When the steel ropes are pulled up, the excess steel ropes are wound around the outer ring of the drum. Poor, can not be applied to large-tonnage electric hoist; Se...

Problems solved by technology

The electric hoist can lift heavy objects high or from one place to another, but during the lifting process, the objects move in space, and most electric hoists need to be hung on the beam, so a long rope is needed to pull the hoist. The hook moves up and down. Most of the existing electric hoists are pulled by steel ropes. The steel ropes are easy to expand and contract. When the steel ropes are pulled up, the excess steel ropes are wound around the outer ring of the drum. Poor, unable to apply to large-tonnage electric hoists; Second, the excess steel rope is easy to cause entanglement when it is wound outside the drum

Therefore someone designs and adopts the chain to pull the hook, the chain strength is high, the load-bearing capacity is good, the gear teeth of the transmission gear drive the chain up and down, and the redundant chain falls into the bag containing the chain from the other side of the transmission gear when rising, but Most of the existing electric chain hoists use electric control to move the electric hoist. In some small factories or small workshops, the space is very small. Using electric trolleys is a waste and consumes more resources. How to use electric hoists in an energy-saving manner? Hulu, become the problem we need to solve now
