Description

Drop hammer type flexible pavement crushing engine

Technical field

The utility model belongs to the highway maintenance machinery field, promptly a kind of drop hammer type flexible pavement crushing engine.

Technical background

At present, need excavate (or milling) for flexible pavement as the processing of hole groove, You Bao, be full of cracks, crack, locality infringement such as loose and clean then and heat carburetion, oil spout, mix and stir the bituminous concrete that paves, several work such as compacting come maintenance.Bituminous concrete is different from cement concrete etc., and other contains certain fragile materials, and its thermostability is relevant with the dynamic stability of the property of softening, viscosity and bituminous mixture.So the machinery knives of broken cement concrete pavement can't broken asphalt concrete pavement.In addition, the excavation asphalt concrete pavement has following three kinds of methods in the prior art: one, use milling machine; Two, with electric pick, Hydraulic pick or gas pick; Three, hand excavation.In three kinds of digging modes, have such or such weak point.Milling machine is to be used for milling specially to damage the machinery of flexible pavement.Its advantage be fast, quality is better, weak point be the price of every milling machine higher as every price of LX100 type milling machine at more than 30 ten thousand yuan.Unit list usefulness also must be equipped with multiple maintenance machinery in addition.Operation rate of machinery is low, forms a parked worker for the treatment of of machine work multimachine situation, has strengthened the cost of maintenance work; It is that plant equipment is small and exquisite, cost is low that electric pick, Hydraulic pick, gas pick are used for its advantage of excavated pavement, and weak point is manually-operated, and mechanical oscillation are big, and labour intensity is big, work efficiency is low, operator's working security on road is relatively poor; The hand excavation, its advantage is need not invest to purchase machinery, but that weak point is a labor strength is big, work efficiency is special low and construct dangerous.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, and existing cement concrete pavement crushing mechanism is improved, a kind of drop hammer type flexible pavement crushing engine that is exclusively used in flexible pavement is provided, it is with the combination of rational overall structure and special crushing cutter thereof, the efficient of excavation flexible pavement is greatly improved, also reduces the maintenance working strength of workers simultaneously widely.

This purpose is to realize with following technical proposal: this drop hammer type flexible pavement crushing engine, it comprises the fixed pulley group, be connected with running block by lift cylinder thereon, one end of wire rope is connected with weight, its other end is walked around lifting tackle, running block, be fixed on after the fixed pulley group on the fixed pulley group body, wherein there is chute the weight both sides, it places on the lift rail, there is crushing cutter the lower end of weight, lifting tackle is fixed on the top of lift rail, constituted the hoisting mechanism of weight, lift rail is connected on the translation guide rail by planker, also be connected to oscillating oil cylinder on the planker, it is characterized in that between the chute of described weight both sides and the lift rail 1 centimeter gap being arranged respectively, the cutter hub back side of cutter is vertical plane, with its corresponding front epimere partly be vertical plane, hypomere partly is the inclined-plane, the inclined-plane becomes 30 °～60 ° angles with the back side, the cutter hub back side of cutter and the best angle on inclined-plane are 45 °.

The utlity model has following advantage: it can be used for the road surface excavation of different brackets, each cutting depth 0～200mm, per minute excavation 16 times, excavation thoroughly, improve the quality and the efficient of excavation greatly, for maintenance of surface, it has reached in time, fast, safety, do not block the demand of traffic; In addition, backactor is easy and simple to handle, laborsaving, has alleviated labor strength greatly.

The specific embodiment

In conjunction with the accompanying drawings overall structure of the present utility model and operating principle thereof are described in detail:

As shown in Figure 1, 2, this drop hammer type flexible pavement crushing engine, its formation is: one group of fixed pulley 1 is arranged, be fixed with lift cylinder 3 thereon, one group of movable pulley 2 is equipped with on the top of lift cylinder, support side in fixed pulley group 1 is fixed with steel cable 4, make wire rope walk around fixed pulley group 1, walk around running block 2 again, walk around a lifting tackle 7 then, its other end is connected with the upper end of weight 5.Weight is in and promotes in the track 6, and the weight respective sides has chute, and it moves up and down at the lifting track, and chute and interorbital keep 1 centimeter gap.Weight 5 lower ends are connected to cutter 9, and the cutter hub shape of this cutter is like this, are a cuboid substantially, its back side is vertical rectangular planes, with the front epimere of its corresponding cutter hub partly be vertical plane, hypomere partly is the inclined-plane, it and cutter hub back side structure angle at 45 have constituted the use cutter.Above-mentioned lifting tackle 7 is erected at the top that promotes track 6.Whole lifting or landing mechanism connect by planker 11 and translation track 10 and are one, also are connected to an oscillating oil cylinder 8 by hole 21 on the planker 11.See Fig. 2, between running block 2 and fixed pulley group 1, be provided with the guiding mechanism of lift cylinder, constitute by guide peg 18 and fairlead 19.Wherein guide peg one end and running block support are fixed, and the other end is fixed by fairlead and fixed pulley pack support, make fixed pulley group and running block remain corresponding original position relation.As shown in Figure 3, this translation track 10 is provided with upper and lower track 15,16, and planker 11 is being with hoisting mechanism to slide about on the upper and lower track, does the level adjusting by regulating bolt 17.Translation track is provided with drive sprocket 14, is respectively arranged with driven sprocket 12 on translation track and the planker.They mutually by chain 13 around connection, the two ends of chain 13 are fixed on the planker 11.Wherein drive sprocket drives (omitting among the figure) by gerotor motor.Drag by special-purpose tractor-trailer when whole crushing engine uses and travel.

The operating principle of drop hammer type flexible pavement crushing engine: after hydraulic oil enters lift cylinder, promote its upper piston and move upward, thereby the running block that drives the piston rod top also moves upward.At this moment guide peg moves up and down in fairlead, because of guide peg and running block connect as one, can not depart from so guarantee that running block moves up and down.When running block moved upward, it rose to certain altitude with weight to pull of steel wire after the commutation of top lifting tackle.At this moment make the oil of lift cylinder cavity of resorption be back to fuel tank rapidly, at this moment weight impacts the road surface to be similar to the movement of falling object, to make the special cutter that is contained in the weight lower end, produces huge impact power and side direction horizontal component.Smash bituminous concrete, and the asphalt blocks horizontal sliding is separated with the road floor, reach the excavation purpose.Hoisting mechanism produces and laterally moves is to drive drive sprocket 14 by gerotor motor (not drawing among the figure), drives driven sprocket 12 through chain 13, makes planker 11 and link move left and right thereof, to improve the excavation width.Oscillating oil cylinder 8 shown in Fig. 1 it and planker join, and can work on irregular ground to guarantee machine, and it is directed to be convenient to excavation.
