Abstract
The utility model relates to a dynamic compaction machine balancing suspension hook which comprises a base balancing beam that is provided with a suspension hook body at the lower part. The suspension hook body is rotatably connected with the base balancing beam. Two ends of the base balancing beam are respectively provided with a first hoisting balancing beam and a second hoisting balancing beam. The first hoisting balancing beam and the second hoisting balancing beam are respectively connected with the base balancing beam rotatably through a pin. The dynamic compaction machine balancing suspension hook overcomes a defect of low dynamic compaction efficiency in the traditional dynamic compaction machine. An operation process in which pulley assemblies function reversely and a structure in which two kinds of balancing beams are matched with each other are adopted. Under a precondition that the hoisting capability is ensured, a force-wasting and distance-saving method is utilized for improving operation efficiency of the strong compaction machine. The dynamic compaction machine balancing suspension hook further overcomes the following technical problems in the hoisting process: length deviation of the wire rope, unbalanced force bearing of the hook, loading force offset of ram hammer, etc.
Description
Technical field

Background technology
Dynamic compaction machinery is that a kind of HI high impact that utilizes the high drop of weight to produce can; The material brute force of better performances such as rubble, slabstone, slag is clamp-oned in the ground; And in ground, form pellet pier one by one; Soil forms composite foundation between pier and pier, improving bearing capacity of foundation soil, thereby reduces the equipment of foundation settlement.
Dynamic compaction machinery is in when work, with crane gear the load or the band hammer of 20 tons～40 tons of weights lifted by crane eminence repeatedly earlier, then utilizes automatically-unhooked release load or band hammer, and it is freely fallen.The kinetic energy that load or band hammer fall just can form powerful shock wave and heavily stressed in soil, thereby reaches the intensity that improves ground, reduces compressibilty, improves its opposing purposes such as (shake) hydrodynamic ability, elimination settlement by soaking of shaking.
