Abstract

The invention discloses a lifting device of a dynamic compaction machine. The lifting device comprises a winding drum, a hydraulic control clutch used for being attached to the winding drum so as to drive the winding drum to rotate and brakes used for braking motion of the winding drum. The brakes comprise the hydraulic control main winding brake and further comprise the hydraulic control snub brake. According to the lifting device, the stability of the dynamic compaction machine can be improved. The invention further discloses the dynamic compaction machine which comprises the lifting device.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a lifting device of a dynamic compaction machine. The present invention also relates to a dynamic compaction machine comprising the above-mentioned lifting device. Background technique [0002] With the growth of the construction market of infrastructure facilities, the construction method of dynamic tamping by dynamic tamping machine has been applied to landfills, desert bases, land reclamation, soft soil reinforcement and airport runway hardening in terms of engineering construction and environmental protection coordination etc. [0003] Traditional dynamic compactors mainly include fully mechanical dynamic compactors, fully hydraulic dynamic compactors and machine-hydraulic integrated dynamic compactors. Among them, the machine-hydraulic integrated dynamic compaction machine includes a reel, a clutch and a main reel brake for braking the reel. When the reel nee...
