Abstract
The utility model relates to an unhooking hammer mechanism and a dynamic compaction machine, wherein the unhooking hammer mechanism comprises a hammer body, an unhooking hook head and a locking frame at least in partial locking match with the unhooking hook head. An unhooking rope is connected onto the locking frame, at least a first hammer lifting lug support and a second hammer lifting lug support are arranged on the hammer body, and the unhooking hook head and the locking frame are respectively in movable connection with the first hammer lifting lug support and the second hammer lifting lug support through pin shafts. The unhooking hammer mechanism and the dynamic compaction machine control the separation between the unhooking hook head on the upper portion of a hammer and a lifting hook connection member through a steel rope, and the hammer falls down to achieve the unhooking function of the hammer. The unhooking rope fixed on the hammer falls down with the hammer, so that the problem that a lifting steel rope is overlarge in rebounding and drives the unhooking steel rope to be broken is solved.. Compared with a traditional structure, the unhooking hammer mechanism and the dynamic compaction machine have the advantages of being small in dimension, low in cost, and high in reliability, improving efficient rising height of the hammer, enhancing the hammering capability and the like.
Description
Technical field
The utility model relates to a kind of engineering mechanical device, particularly relates to a kind of unhooking rammer mechanism and dynamic compaction machinery.
Background technology
Dynamic compaction machinery, as shown in Figure 1, that the HI high impact of utilizing the high drop of weight to produce can be clamp-oned the material brute force of the better performances such as rubble, slabstone, slag the construction equipment in the ground, the strong rammer function forms pellet pier one by one in ground, native form compound foundation between pier and pier, thereby to improve bearing capacity of foundation soil, to reduce sedimentation.
Dynamic compaction claims again dynamic consolidation method, namely repeatedly 20～40 tons hammer ram is lifted to eminence with crane gear, then utilize automatically-unhooked release load or band hammer freely to fall, its kinetic energy forms powerful shock wave and heavily stressed in soil, thus improve ground intensity, reduce compressibilty, improve its opposing shake (shake) hydrodynamic ability, Compaction variables etc.Obtained increasingly extensive application in the foundation treatment engineering of its polytype, multiple purpose all over the world.
Detacher is the rammer unhooking device of using on the dynamic compaction machinery, detacher used in the prior art often is the pulling formula, wire rope is owing to have certain elasticity, behind the rammer unhooking, wire rope removes the weight of hammer ram, drives the detacher bounce-back, and detacher is connected with the rope that breaks off relations, the rope that breaks off relations suppresses the bounce-back of detacher, just very easily destroys the unhook wire rope.
The unhooking system of dynamic compaction machinery commonly used generally is comprised of four parts, as shown in Figure 2, mainly comprises suspension hook 11, detacher 12, and hammer ram 13, rope 14 breaks off relations.Wherein detacher and suspension hook 11 adopt axle or adopt the wire rope binding fixing, rope 14 leading blocks that pass on the suspension hook 11 that break off relations, and fixing with detacher 12, the other end and the turntable of the rope 14 that breaks off relations are fixed (not shown among Fig. 2).The course of work of existing unhooking system is: hammer ram 13 rises to certain height, the rope 14(length that breaks off relations is fixed) tension, rely on tightening force to drag detacher, realize breaking off relations, behind the stressed Condition of Sudden Unloading of raising line, drive suspension hook 11 and detacher 12 bounce-backs under self flexible effect, the rope 14 of breaking off relations this moment is connected with detacher 12, and the generation that rebounds of inhibition detacher 12.
In addition, rammer can be an important parameter of dynamic compaction machinery, is the product of weight and the hammer ram rising maximum height of hammer ram; Along with technology develops to the large dynamic compaction machinery that rams energy, the lifting altitude of hammer ram and the weight of hammer ram are increasing, hoist rope length and stressed increase.During unhook, the energy that wire rope stores increases; After the unhook, the detacher bounce-back increases, and bounce-back height h excessive (as shown in Figure 1) is easy to cause the disconnected phenomenon of rope (rope is long fixing) bullet that breaks off relations.At present, the method that the medium and small dynamic compaction machinery that rams energy solves the rope that breaks off relations generally adopts the quantity that increases the unhook rope and the diameter that increases wire rope, but the large dynamic compaction machinery that rams energy adopts the method not meet the demands.
