Abstract
The invention discloses an automatic control device of a dynamic compaction machine. When the dynamic compaction machine is lifted up a hammer, a movable switching mechanism is in contact with a limiting mechanism, and then a hook lifting valve on the moving switching mechanism is closed; at the moment, the hammer is lifted in place according to a set height and starts falling freely, and the movable switching mechanism runs towards a brake mechanism along a screw rod track; after the hammer falls to the ground and finishes work, the movable switching mechanism can enable a drum brake pilot valve of the dynamic compaction machine to be opened, and a brake works to realize drum brake and stop rotation; and at the moment, the hook lifting valve on the movable switching mechanism is opened, and a brake valve is closed simultaneously. The hammer starts to be lifted when the drum goes upwards, and the manner moves in circles to realize an automatic control effect of the dynamic compaction machine.
Description
The invention relates to the invention of dynamic compaction machinery automaton, particularly a kind ofly control the invention that strong hammer ram rises and falls automatically.
Existing dynamic compaction machinery all wants the staff to link up with operation to the hammer ram place under the boom before in work progress, playing hammer; And want driver and hook personnel to cooperatively interact and could accomplish, not only efficient is low but also very dangerous, has security incident to take place in the time of in the construction; Moreover; After hammer ram broke off relations in the dynamic compaction machinery operation process, because rebound effect, suspension hook and detacher can clash into to the armed lever direction; Common way is to fasten on arm alleviating impact with old tire, but that arm is broken is unavoidable.
The purpose of this invention is to provide a kind of fully need not the artificial dynamic compaction machinery automaton of hanging hammer ram.
The dynamic compaction machinery of automaton has been removed artificial extension hammer ram from work progress method has been installed; Rising and falling of hammer ram also accomplished by control device automatically in the dynamic compaction machinery work; Saved the driver and much bothered, improved the operating efficiency of dynamic compaction machinery, safe construction has had guarantee.
The present invention is achieved in that the dynamic compaction machinery automaton is by chain drive, and the screw rod track moves switching mechanism, position-limit mechanism, arrestment mechanism and the compositions such as hammer ram that have pulley.
In dynamic compaction machinery reel forward or reverse, the screw rod track makes and moves switching mechanism along screw rod track linear reciprocating motion under the drive of chain drive.
Dynamic compaction machinery plays when hammer, moves switching mechanism to the position-limit mechanism direction running, when with the position-limit mechanism contact mobile switching mechanism in back on a hook valve be closed; Hammer ram promoted by the height that is provided with and put in place this moment; Hammer ram begins free-falling, move switching mechanism along the screw rod track to the arrestment mechanism direction running, after hammer ram lands and finishes the work; Moving switching mechanism opens dynamic compaction machinery reel braking pilot valve; The braking of brake work realization reel is stopped the rotation, be arranged on a hook opening of valves that moves on the switching mechanism this moment, the while brake valve cuts out.Up hammer beginning of reel so moves in circles, and realized the dynamic compaction machinery effect of control automatically.
To combine accompanying drawing that the present invention is done detailed explanation below:
Fig. 1, be the principle schematic that the present invention has.
Fig. 2, be gas circuit sketch map of the present invention.
Fig. 3, be hammer ram sketch map of the present invention.
With reference to Fig. 1: the sprocket wheel of screw rod track 2 one ends is linked to each other by chain with the sprocket wheel on being installed in reel; Along with the mobile switching mechanism 3 on the rotary screw track 2 of reel moves back and forth between the A-B both direction; 2 machine controls are installed in this mechanism play hook valve 7; (air valve or fuel tap) is connected through the hook working cylinder that rises on pipeline and the reel, and the machine control plays hook valve 7 front ends and is provided with a pressing plate 6 of being with locating shaft, and pressing plate can the closure plane control play hook valve 7 contact afterwards with position-limit mechanism 4.
The front end of position-limit mechanism 4 is equipped with buffer spring; Required thrust when the elastic force of this buffer spring is closed greater than machine control valve 7; Purpose is can guarantee that the machine control rises can normally close after hook valve 7 contacts with it, when mobile switching mechanism 3 continues to move ahead, is unlikely to change bad parts again.
The effect of position-limit mechanism 4 is hoisting depths of restriction hammer ram, and this height can be adjusted arbitrarily by screw rod 5 according to the construction needs.
Be provided with 2 moving pilot valves 8 of machine control on the arrestment mechanism; This pilot valve can be opened by mobile switching mechanism 3; And control brake valve reel braking is stopped the rotation; Arrestment mechanism is provided with an one-way only operation cylinder 9, plays hook valve 7 through pipeline and machine control and is connected, and its effect is that the moving pilot valve 8 of compression buffer spring 10 closure planes control stops the reel braking.
Buffer spring 10 on the arrestment mechanism is to promote to play cushioning effect when arrestment mechanism continues to move ahead a segment distance at mobile switching mechanism 3, makes it can not damage component.The thrust that the elastic force of buffer spring is opened greater than the braking pilot valve.
Between the moving pilot valves 8 of two machines control of arrestment mechanism, be provided with the fore-set that can regulate 7 relative with the locating shaft of pressing plate 6, effect is through pressing plate 6 the machine control to be played hook valve 7 to open and make reel work begin to promote hammer ram.
With reference to Fig. 2
The machine control rise the hook valve 7. open back reel working cylinder 3. the one-way only operation cylinder 9. the engine throttle working cylinder 2. work simultaneously; 9. the one-way only operation cylinder compresses the moving pilot valve of buffer spring closure plane control and stops braking; Reel plays hook to begin, and the throttle working cylinder raises speed motor automatically.
In order to prevent that machine control valve from breaking down, be provided with two machine controls and play the 7. parallelly connected use of hook valve to guarantee the dynamic compaction machinery normal operation.
The moving pilot valve of machine control that equally also is provided with two parallel connection uses is 8. in proper working order to guarantee brake, prevents that the reel brake failure from damaging parts.
In order to prevent because of the tolerance flow velocity prolongs the reel braking time slowly, brake valve 6. adopt separately with gas receiver 1. ways of connecting to improve air feed speed, the braking effect of assurance reel.
4. and 5. two hand control valves are installed in driver's cabin can be artificial from line operate when not needing to play hammer automatically.
Being provided with wire rope and pulley 2 on the hammer ram 1 on fixed block 2 reels with reference to Fig. 3 hammer ram of the present invention 1 top directly to be connected in order preventing to carry hammer wire rope and to take off groove backplate 3 is arranged to guarantee that wire rope can not take off groove in the following radius of pulley.
Other parts such as suspension hook and detacher are not installed between arm top and the hammer ram,, thereby have been guaranteed the safety of equipment so arm can not receive any bump when hammer ram falls.
