Abstract

The invention discloses a lifting device. The lifting device comprises a base. A supporting mechanism, a lifting mechanism and a safety protection mechanism are arranged on the upper surface of the base. A fixed mounting mechanism is arranged on the lower surface of the base. The supporting mechanism is composed of a set of stand columns arranged on the upper surface of the base, rectangular grooves formed in two opposite inner side surfaces in the set of stand columns correspondingly, first telescopic motors arranged on the inner lower surfaces of the rectangular grooves, lifting blocks arranged at the telescopic ends of the first telescopic motors, round grooves formed in two opposite side faces of the lifting blocks, first bearings arranged in the round grooves, rotary rods inserted in the set of first bearings, hoisting shafts arranged on the rotary rods in a sleeving mode, and anti-slip sleeves arranged on the outer surfaces of the hoisting shafts in a sleeving mode. A PLC control system is arranged on the side surface of the base and electrically connected with the supporting mechanism, the lifting mechanism and the safety protection mechanism. The lifting device has the beneficial effects of being high in safety and practicability.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a lifting device. Background technique [0002] In the construction process of the construction site, it is necessary to transport heavy objects to high-level workers for operation. Usually, such work is completed by lifting equipment. , also known as the crane. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. Due to the lack of outriggers for hoisting and hoisting, some accidents often occur, and the driving speed is faster than that of crawler cranes (crawler cranes); the operation is stable, the lifting capacity is large, and it can lift and walk within a specific range, but the road must be smooth and solid. , The tire p...
