Wedge-shaped self-locking pounder unhooking device

Abstract

A wedge-shaped self-locking pounder detacher comprises a guide component which is hollow in the inner portion and an automatic unhooking component matched with an inclined inner side face of the guide component. The automatic unhooking component comprises a lifting support, support talons, an oil cylinder and connecting bars. Lifting lugs are arranged on the top surface of the lifting support. The side surfaces of the lifting support are connected with the upper portion of the supporting talons in a pivoted mode. Two or more supporting talons are arranged symmetrically with a longitudinal axis of the lifting support as a symmetric axis. The outer surface of each supporting talon is frictionally combined with the inner surface of the guide component. The oil cylinder is fixed on the center portion of the lower surface of the lifting support. The lower end of each supporting talon is connected with each corresponding connecting bar in a pivoted mode. The other end of each connecting bar is connected with the lower end of the oil cylinder in a pivoted mode. According to the automatic detacher, a guide principle is adopted to achieve automatic hooking of the detacher. Automatic unhooking can be achieved in any position according to requirements. The automatic hooking of a guide device can be achieved through a control device when the guide device falls down. In addition, simple structure of the wedge-shaped self-locking pounder detacher is achieved; safety of operation is improved and manufacturing cost is reduced.

Description

technical field [0001] The present application relates to the technical field of engineering machinery, in particular to an automatic uncoupling device of a dynamic compaction machine. Background technique [0002] In the process of civil construction projects, it is necessary to use lifting equipment to repeatedly lift the rammer weighing tens of tons (sometimes weighing up to 40 tons) to a high place, and then use the automatic decoupling to release the load or fall freely with the hammer. Strong shock waves and high stress are formed in the soil, thereby increasing the strength of the foundation, reducing compressibility, improving its ability to resist vibration (shock) liquefaction, and eliminating collapsibility. [0003] All over the world, dynamic compaction machines have been increasingly widely used in various types and purposes of foundation treatment projects. During the operation of the dynamic compaction machine, it is necessary to frequently repeat the operat...

Problems solved by technology

One opening and one opening of the lifting lug realizes the hooking and unhooking of the head of the rammer, but the disadvantage is that the rammer lifts a certain height to unhook during work. If the rammer deviates to a certain displacement, automatic hooking cannot be realized, and the rammer lifts The force is realized by the pressure inside the cylinder. As the weight of the rammer increases, the design of the cylinder is larger and the cost is high.

The rammer rises to a certain height, and the decoupling of the rammer adopts the extension of the oil cylinder to realize the decoupling of the rammer. The decoupling of the rammer is slow, and often jams, and it is impossible to achieve fast decoupling
