Background technology
Tamping machine is widely used in the ground of engineering construction and processes, and the kind of tamping machine is a lot, has breast-stroke, vibration-type, galloping formula, also has lift heavy paddle type mill.Lift heavy paddle type mill tamping machine is wherein to utilize weight-lifting equipment repeatedly hammer ram to be hung to eminence, then allows hammer ram freely fall, and ground is formed to powerful impact, with compacting foundation.The hoist rope of general hoisting crane is to lift by crane and unload hammer ram by hooking device, at present the hooking device of more common hammer ram is that form with rope is connected with hoist rope mostly, as shown in fig. 1, therefore, when hammer ram comes off, the stressed Condition of Sudden Unloading of the hoist rope of hoisting crane, under the elastic reaction of self, drive hooking device to rebound up and down, because hooking device and hoist rope are for being flexible coupling, when therefore hooking device rebounds up and down along with hoist rope, also can rock by wigwag motion, and then cause hoist rope also to rock thereupon, hooking device is from bounce-back like this, rock the static time gap that gets off to carry out next time lifting long, inefficiency, the design people improves for this deficiency, this case produces thus.
Utility model content
The utility model provides a kind of hooking device of automatically-unhooked tamping machine hammer ram, by the improvement to hooking device, solves traditional hooking device and rocks large deficiency.
For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of hooking device of automatically-unhooked tamping machine hammer ram, include eccentric suspension hook, latch hook structure and support, described eccentric suspension hook is articulated in the lower end of support by tie bolt, latch hook structure is for the eccentric suspension hook of locking, by lock frame and lock pin, formed, one end of lock frame is articulated in the middle part of support by connecting pin, the other end connects the rope that breaks off relations, lock pin is arranged on the middle part of lock frame, the position of the straight portion of corresponding eccentric suspension hook, under free state, lock pin holds out against the straight portion at eccentric suspension hook, by eccentric suspension hook locking, particularly this hooking device also includes attaching parts and Connection Block, described top of the trellis is articulated by attaching parts and Connection Block, this attaching parts includes pivot pin, stop collar and two clips.
Described support is comprised of two symmetrical lamellar bodies, described Connection Block protrudes the two pivot ears with pivot hole downwards, the pivot pin axle of described attaching parts is located on the pivot hole of this Connection Block pivot ear, parallel and being set on pivot pin of interval of support two lamellar bodies can be rotated around pivot pin, the middle part that stop collar is set in pivot pin is positioned between support two lamellar bodies, and two clips are held tightly respectively on the pivot pin between two lamellar bodies and Connection Block pivot ear.
The top of described support two lamellar bodies is provided with the hole of passing through for pivot pin.
Described clip be integral type structure or by upper and lower two part sealed composition.
Adopt said structure, the locking that the eccentric suspension hook of the utility model departs from lock pin be take tie bolt and is done the deflection of predetermined angle as axle, by after hammer ram unloading, support force impact is around the resistant deflection of pivot pin, and under drag effects, can make under support and suspension hook fast and stable, overcome traditional hook structure and rocked large deficiency after hammer ram unloading, and this structure organically combines crane hook and hammer ram hooking device, whole static load structural focus line is overlapped with hammer ram line of centers or approaches to overlap, thereby effectively reach, reduce to rock, the object of increasing work efficiency.
