Abstract

The invention discloses a segmented retardant discharging device. The segmented retardant discharging device comprises an automatic hooking device and a retarder, wherein the automatic hooking device is positioned below the retarder and is connected with the retarder, a spring feeler lever is arranged above the retarder, and the retarder is internally provided with a hydraulic oil path used for controlling hydraulic pressure of the retarder. According to the segmented retardant discharging device disclosed by the invention, by reducing the hydraulic pressure of the retarder in a grading mode, tensile force of a steel wire rope for hanging a heavy hammer is gradually reduced, and the heavy hammer is subjected to putting down in a stair-shaped slow descending mode from a step releasing mode, so that impact to a system due to heavy hammer release is reduced, the rebound of a cargo boom is small, the rope disordering probability of the steel wire rope is low, the abrasion of the automatic hooking device is slight, the whole machine vibration is slight, and the service life is long.

Description

Technical field

[0001] The invention relates to a sectioned slow-speed discharge device. Background technique

[0002] Impact machinery refers to a sudden change in the state of a mechanical system or part of it that is subject to sudden, abrupt and non-periodic excitation, which occurs much faster than the natural vibration period of the system, such as continuous wall grabs and dynamic compactors. The dynamic compaction machine relies on the high-altitude release of the heavy hammer to impact the ground operation, that is, the heavy hammer is raised to a height of tens of meters and released instantly. At present, the high-altitude release of the heavy hammer mainly adopts the decoupling mechanism. Typical decoupling mechanisms include mechanical decoupling devices, automatic hooking devices and hydraulic decoupling devices.

[0003] The existing mechanical decoupling device uses the self-locking property of the dead point of the mechanism to raise the weight of dozens of tons t...
