Abstract

The invention discloses a lifter and an operation method thereof. The lifter comprises a rack, a lifting driving mechanism, a lifting arm assembly and a sensing assembly. The lifting driving mechanismcomprises a chain, a chain wheel, a lifting motor and a control electric box; the lifting motor drives the chain to move up and down through the chain wheel; the lifting arm assembly is connected tothe chain and used for taking and placing a hopper and driving the hopper to move up and down along with the chain; and the sensing assembly comprises a position sensing piece, a descending in-place sensor, a descending limiting sensor, an ascending limiting sensor and an ascending in-place sensor. According to the lifter, rapid ascending and descending can be achieved within the safety range, material conveying and hopper taking away are achieved, efficiency is improved, and time is saved; moreover, a lifting mechanism is stable in operation and can accurately reach a corresponding height asrequired; and the structural design is simple and reliable, and maintenance and repairing are convenient.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator and an operating method thereof. Background technique [0002] At the construction site, lifting and handling equipment is required to pick and place the hopper filled with concrete or the empty hopper. The traditional lifting and handling equipment used on the ground, including forklifts, does not meet the needs of the construction site. There is an urgent need for a lifting and handling equipment dedicated to construction sites to improve work efficiency and save labor. Contents of the invention [0003] The object of the present invention is to provide a lift and its working method, so as to improve working efficiency and save labor. [0004] In order to achieve the above-mentioned purpose of the invention, the first aspect of the present invention provides a lift, including a frame, a lift drive mechanism, a lift arm assembly and a sensor assembly; the lift ...
