Description
Technical field
The invention belongs to technical field of engineering machinery, being specifically related to the tight geotechnical engineering construction equipment with throwing off action of a kind of extension that can be used for hammering into shape.
Background technology
Tamping machine equipment is in operation process, and the extension needing to repeat frequently hammer ram is tight, hammer ram is promoted to the action that certain altitude is thrown off again.At present, the common crawler crane pattern that hammer ram operation adopts, increases the mechanical lever locking device controlling suspension hook and rotate.During operation, manual operation hook device is linked up with, and hoist hammer ram, and lever outer end is connected with main frame by wire rope, and arrive after setting height, wire rope is tightened, and pull lever goes out of lock position, and suspension hook rotation, realizes rammer unhooking, free-falling.When the method breaks off relations, hammer ram is separated slowly with suspension hook, makes suspension hook and boom device produce very large swing, reduces the life-span of associated mechanisms, suspension hook mouth of hook serious wear; Need artificial to carry out hook-hanging motion, to work under hard conditions and dangerous; Rammer unhooking needs to be wire rope, and adjustment hammer ram height is inconvenient, and hammer ram easily pulls and departs from commitment positions, equipment availability inefficiency by wire rope.
Summary of the invention
The technical problem to be solved in the present invention be tamping machine equipment take off in hammer process swing large, dangerous large, efficiency is low, provide a kind of and can reduce amplitude of fluctuation, job safety, provide that the hydraulic pressure of operating efficiency is automatically de-hangs hammer device.
Technical scheme of the present invention realizes in the following manner: a kind of hydraulic pressure is automatically de-hangs hammer device, comprise de-hammer mechanism and hammer ram, described de-hammer mechanism comprises hydraulic cylinder, weight slide block is arranged with outside the cylinder body of hydraulic cylinder, be provided with limited block above weight slide block, below is provided with flange end, limited block and flange end are arranged on the cylinder body of hydraulic cylinder, connecting rod hanger below weight slide block is hinged with double link, double link and monotroded bar are hinged and connected, monotroded bar is hinged on the piston rod of hydraulic cylinder, is provided with spring between piston rod end and flange end.
The top of described hammer ram is funnel-form, and hammer ram sidewall is provided with rectangular slot.
The present invention collects mechanical, electrical, liquid integrative control but do not need hydraulic power supply, and can realize the automatic disengagement hammered into shape and hang tight, do not need workman's manual working, operation is safer.Realize de-hammer by remote control, can provide operating efficiency, dropping process and the disengagement action of hammer ram are carried out simultaneously, and its impact is little, amplitude of fluctuation is little.

Detailed description of the invention
As shown in drawings, a kind of hydraulic pressure is automatically de-hangs hammer device, comprise de-hammer mechanism and hammer ram 8, described de-hammer mechanism comprises hydraulic cylinder 2, weight slide block 9 is arranged with outside the cylinder body of hydraulic cylinder 2, be provided with limited block 3 above weight slide block 9, below is provided with flange end 11, limited block 3 and flange end 11 are arranged on the cylinder body of hydraulic cylinder 2, connecting rod hanger 10 below weight slide block 9 is hinged with double link 6, double link 6 and monotroded bar 7 are hinged and connected, monotroded bar 7 is hinged on the piston rod 14 of hydraulic cylinder 2, is provided with spring 15 between piston rod 14 termination and flange end 11.
The height adjustable of limited block 3, and then the position that can control weight slide block 9.
In the present invention, electrical installations system is made up of battery pack, wireless transmit controller and the wireless receiver be arranged on bottom hydraulic cylinder 2, and hydraulic control system comprises hydraulic jack, unloader and fuel tank etc.By the action of wireless receiver hydraulic control electromagnetic valve during use, thus de-controlled in wireless of hanging hammer action can be realized.
The top of described hammer ram 8 is funnel-form, and hammer ram 8 sidewall is provided with rectangular slot 5.
The course of work of the present invention is as follows: when hammer ram 8 drops on ground, and upwards, de-hammer device of hanging falls, and double link 6 first contacts with hammer ram 8 in the funnel-shaped opening at top.Now, the de-Action of Gravity Field hanging hammer device is relied on, by double link 6 by weight slide block 9 upwardly, double link 6, monotroded bar 7 close and fall into hammer ram 8 afterbody, after falling into, due to weight slide block 9 Action of Gravity Field, double link 6, monotroded bar 7 are also pushed open by slide downward.Jack up unit lifts by crane monotroded bar 7, and unloader is in closure state, and piston rod 14 is in retracted mode, can not extend.Lifting force is passed to double link 6, and double link 6, monotroded bar 7 open, and double link 6 contacts with the funnel surface of hammer ram 8, and double link 6 is spacing by flange end 11, and double link 6, monotroded bar 7 open and be to a certain degree stuck in afterwards in fluting 5, upgrade hammer ram 8, completes and hangs tight action.
The hydraulic pressure that hoists is automatically de-hangs hammer device, and now unloader is still in closure state, and in hydraulic cylinder 2 rod chamber, oil pressure keeps, and drives hammer ram 8 to rise.Hydraulic system plays overload protective function by overflow valve, and when transshipping when hoisting, off-load opened by overflow valve, the de-hooking device safety of protection.
After hammer ram is promoted to proper height, electrical system wireless launcher sends signal, hydraulic pressure is automatically de-hangs the receiver Received signal strength installed bottom hydraulic cylinder in hammer device, Controlling solenoid valve action, and unloader is opened, rod chamber 4 quick relief of hydraulic cylinder, drive piston rod 14 to extend by the Gravitative Loads of hammer ram 8, double link 6, monotroded bar 7 close due to the effect of hammer, realize hammer and throw off action, hammer dropping process and disengagement action are carried out simultaneously, and hydraulic pressure automatically de-hammer device of hanging impacts little.
After hammer disengagement action completes, pull piston rod 14 to reset by spring 15, hydraulic pressure automatically de-hammer device of hanging recovers SBR, prepares working cycles next time.
