The specific embodiment
As shown in Fig. 1 ~ 4, the utility model comprises crane gear 1, positioning hanger device 2 and guide rod hammer ram 4, described positioning hanger device 2 comprises hydraulic cylinder 5 and guiding protective cover 13, hydraulic cylinder 5 is connected with electrofluidic control device 7, the piston rod of hydraulic cylinder 5 is hinged by bearing pin 10 and suspension hook 12, spring 8, the upper end of spring 8 hangs on the hanger of hydraulic cylinder top, guiding protective cover 13 passes through fixedly limiting plate 9 of bolt 6, limiting plate 9 bottoms are provided with spacer pin 11, stretch out above spacer pin 11 at suspension hook 12 two ends, and guiding protective cover 13 bottoms are horn mouth; Described guide rod hammer ram 4 comprises guide head 13, positioning tube 14 and hammer body 16, and the top of guide head 13 is conical, and the top of positioning tube 14 is that taper, bottom are cylindrical shape.Hammer body 16 is connected with positioning tube 14 by junction plate 15, connecting bolt.
Described crane gear is provided with the high control device 3 of automatic survey, automatically surveys high control device 3 and comprises pressure sensor, encoder and center processor, and pressure sensor is arranged on crane gear elevator equalizing valve place, and encoder is connected with elevator.When suspension hook hangs weight, center processor receives the signal controlling encoder tanks that pressure sensor transmits, along with the lifting encoder of weight is counted the elevator rotating cycle, when arriving the setting number of turns (setting height=individual pen rope capacity * rotating cycle), center processor is controlled elevator braking remote control simultaneously and is controlled 2 unhook of positioning hanger device, thereby realizes fixed high automatic unhooking function.
Positioning hanger device 2 and guide rod hammer ram 4 courses of work are as follows: the piston rod of hydraulic cylinder 5 is flexible drives suspension hook 12 motions, and the spacing drive suspension hook 12 by spacer pin 11 opens and closure, realizes with the disengagement of guide rod hammer ram 4 and hangs tight action.Wherein the top of hydraulic cylinder 5 is connected with the suspension hook of crane gear, electrofluidic control device 7 is fixed on the top of positioning hanger device, when guide head 13 enters guiding protective cover 13 horn mouth, under Action of Gravity Field, positioning hanger device 2 continues to move down, under the effect of positioning tube 14, make positioning hanger device 2 and guide rod hammer ram 4 align, under Action of Gravity Field, suspension hook 12 is opened, guide head 13 enters in suspension hook, suspension hook 12 tangles guide head 13 by gravity closing, so just guide rod hammer ram 4 is tangled until be promoted to setting height.After arriving setting height, the electrofluidic control device 7 on positioning hanger device 3 tops moves down hydraulic cylinder 5 piston rods and suspension hook 12 under the double action of the control of automatically surveying high control device 2 and guide rod hammer ram 4 gravity, while in folding process, encountering spacer pin 11, suspension hook is opened, thereby make positioning hanger device 2 break away from and realize the action of breaking off relations with guide rod hammer ram 4, after breaking off relations, rely on the spring force cylinder piston rod to reset.
Described crane gear 1 is dynamic compaction machinery, crawler crane, walk type crane or rubber tired crane.
Described hammer body 16 is pane hammer, plane bottom hammer, bomb shape hammer, oval hammer, pyriform hammer, cylindrical hammer or the peripheral hammer body with outside cutting knife.
In practical work process, under the rotation of crane gear 1 elevator, by tractive wire rope positioning hanger device 2, utilize deadweight to fall the guide head 13 that entangles guide rod hammer ram 4 tops, forcing under dynamic action of vertical and horizontal counter-force point, force positioning hanger device 2 automatically to tangle the guide head of guide rod hammer ram 4, then after guide rod hammer ram 4 being promoted to design elevation, automatically survey high control device and can send remote signal to location hooking device 2, positioning hanger device 2 receive signal after cylinder action hammer ram 16 is deviate from, and then make hammer body rush at ground by the mode of freely falling body, and then make positioning hanger device 2 utilize deadweight to fall and tangle guide rod hammer ram 4, automatically tangle with the repeated multiple times above-mentioned hammer body fall-automatic positioning hanger device of high unhooks-hammer body that hoists-determine that carries out the operation that guide rod hammer ram-hammer body hoists, banketed during this time and be bulldozed the composite foundation base of ramming again last acquisition high-bearing capacity.
