The invention provides a cylinder driven derricking mechanism of a dynamic compaction machine and the dynamic compaction machine. The derricking mechanism comprises a firs cylinder, a first fixed pulley block, a first movable pulley block and a first rope, wherein the first end of the first cylinder is used for connecting a vehicle body of the dynamic compaction machine, and the second end of the first cylinder is connected with the first movable pulley block; after the first rope is wound on the first fixed pulley block and the first movable pulley block, the end of the first rope is used for connecting a boom head of the dynamic compaction machine; when the first cylinder makes telescopic movement, the first movable pulley block moves along with the first cylinder, and the distance between the first fixed pulley block and the movable pulley block increases or decreases to drive a boom of the dynamic compaction machine to swing by taking a hinged point of the boom and the vehicle body as a center so as to realize the raising and descending of the boom. The movable pulley block is driven by the cylinder, and the stroke is expanded by the fixed and movably pulley blocks, accordingly, the cylinder driven derricking mechanism provided by the invention has the advantages of simple structure, convenience in maintenance, stable operation, high reliability and the like.
Description
technical field [0001] The present invention mainly relates to the field of engineering machinery, in particular to an oil cylinder-driven luffing mechanism of a dynamic compaction machine, and a dynamic compaction machine including the luffing mechanism of the dynamic compaction machine. Background technique [0002] Dynamic tamping machine is a kind of construction machinery used for impact compaction of materials or foundations, widely used in the construction of industrial and civil buildings, warehouses, yards, docks, airports, road and railway roadbeds, artificial islands, etc. . The luffing mechanism is an important component of the dynamic compaction machine. Through the luffing mechanism, the pitch angle of the boom of the dynamic compaction machine can be changed to realize the lifting and lowering of the boom, and then the rammer of the dynamic compaction machine can be hoisted to different heights. When the rammer is released to make it fall freely, it can give ...
