Problems solved by technology

When this method is unhooked, the tamper is separated from the hook slowly, causing the hook to generate a large swing speed, reducing the life of the relevant mechanism, and the hook mouth is severely worn; it is necessary to manually reset the lever and the hook, and the working conditions are poor and dangerous; need It is inconvenient to adjust the decoupling height of the tamper by tying the wire rope

Embodiment Construction

[0019] The hydraulic uncoupling device for the rammer of the dynamic compaction machine is composed of a mechanical device and a hydraulic control system, of which:

[0020] a. The mechanical device is composed of hydraulic cylinder 3, connecting rods 5 and 7, lifting lug 9 and spring 12. Oil cylinder 3 and upper connecting rod 5 are connected by hinge shaft 4, and upper connecting rod 5 and lower connecting rod 7 are connected by hinge shaft 6. , The lower connecting rod 7 is connected with the lifting lug 9 through the hinge shaft 8, and the lifting lug 9 is connected with the piston rod 13 through the pin shaft 11, and each component is rotatable relative to the connecting shaft. The piston rod 13 is connected to the cylinder body of the oil cylinder 3 through the spring 12; the hook between the tamper 10 and the decoupler is realized through the groove between the two lifting ears 9 and the head of the tamper 10 with the flange.

[0021] b. The hydraulic control system con...

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 ...
