Abstract

The present invention belongs to the field of engineering machinery technology, and the hydraulic tripper of strong rammer includes mechanical unit and hydraulic control system. The mechanical unit consists of oil hydraulic cylinder, link rod, lifting lug, and spring; and the hydraulic control system consists of cartridge inserted valve, non-return valve, oil tank, throttle valve, overflow valve and electromagnetic change-over valve. The present invention needs no manual hanging operation in controlling the rammer descent from any lifted height. The rammer descent is synchronous with tripping course, and tripping is fast, complete, small in impact, and low in the wear of the lifting lug. The present invention is suitable for geotechnical engineering.

Description

technical field

[0001] The invention belongs to the technical field of engineering machinery. The utility model relates to geotechnical engineering construction equipment, which can be used for hooking and unhooking work of a tamper of a dynamic compaction machine. Background technique

[0002] During the operation of the dynamic tamping machine, it is necessary to frequently repeat the operations of hooking the rammer, lifting the rammer to a certain height and unhooking and falling. At present, the hook used in it adopts the type of ordinary crane hook, and a mechanical lever locking device for controlling the swing of the hook is added. During operation, manually operate the lever to make the hook in the swing lock position, hook the hook, and lift the rammer. The outer end of the lever is tied with a wire rope, and the other end of the wire rope is fixed on the body of the dynamic tamping machine. After reaching the set height, the wire rope is tightened, the lever is ...
