As Fig. 1,2, hammering blow type impacting machinery 10, comprise the soil punching machine 12 that a band drops hammer and this punching machine 12 is fixed on fixed part 14 on the carrier loader 16 of belt wheel, carrier loader 16 has vehicle frame 18 and anterior draw-gear 20, utilize traction adorn 20 with carrier loader 16 with draw carrier such as truck and be connected.As Fig. 3,4,5, a pair of channel bar 24 vertical casings 22 that pass through, channel bar 24 tops connect with parallel bar 26.Channel bar 24 bottoms have one has the chassis on curved surface chassis 30 to prop up pad 28, and curved surface chassis 30 is suspended on the slippery supporting piece 32, and slippery supporting piece 32 links to each other with channel bar 24.Curved surface chassis 30 can be done limited free activity around the rest pad axle center in the suspension space.Dropping hammer 34 can be slided up and down in casing 22 by channel bar 24 guiding, is connecting the control member 36 that drops hammer 26 of two parallel bars and is being hydraulic cylinder in the present embodiment, and the piston rod 38 of hydraulic cylinder links to each other with 34 the upper end of dropping hammer.As Fig. 4, another hydraulic cylinder 40 is connected in (bearing 42 is connected on the parallel bar 26) between casing 22 and the bearing 42.Braced structures 44 can be rotated (Fig. 1) on carrier loader 16 back pivot 13, and includes the rail structure 46 of a parallelization, between vehicle frame 18 and braced structures 44 hydraulic cylinder 48 is housed.Connection bearing 52 on the casing 22 is connected punching machine 12 with supporting construction 44, bearing 52 can move horizontally on rail structure 46.As Fig. 3, be positioned on the fulcrum 49 of casing 22 for sprocket wheel in horizontal drive 47 present embodiments in the driver part, by hydraulic-driven, the counterpart chain engages in sprocket wheel 47 and the supporting construction 44, sprocket wheel 47 drives casing 22 and closes parts along supporting construction 44 move left and right when rotating.
The power of above-described all hydraulic parts is supplied with by hydraulic power parts 54, as shown in Figure 4.Power part 54 is fixed on the underframe 18 of carrier loader 16.On carrier loader, can carry out the manual control of hydraulic pressure circulation.
Fig. 1 to Figure 2 shows that punching machine 12 is in not operation, in the state that is suitable for transporting.
Fig. 3 is to Figure 5 shows that punching machine 12 is in the state that carries out the soil compression operation.
Punching machine is that the action by hydraulic cylinder 48 makes supporting construction 44 clockwise rotate around pivot 13 shown in Figure 1 from the non-operating state to the mode of operation, and as Fig. 1, Fig. 3, shown in Figure 4, the casing 22 and the parts that link thereof also clockwise rotate thereupon.After the rotation, machinery is in the soil compression mode of operation, and punching machine 12 is in and carrier loader 16 vertical direction.
It is by hydraulic cylinder 48 actions supporting construction 44 to be rotated counterclockwise around pivot 13 that punching press poplar 12 changes non-operating state over to from mode of operation, simultaneously.The casing 22 and the parts that link thereof rotate counterclockwise thereupon.When machinery is in non-operating state, as Fig. 1,2 punching machines 12 almost all above carrier loader, with convenient transportation.
Native gauge pressure is real-time when carrying out, and the carrier loader rear portion is facing to the place that needs compacting, and the bearing bracket 56 on the sole 18 can stretch with ground and contact.Can see that from Fig. 1 when machinery is under the state that not operation is suitable for transporting, bearing bracket 56 is withdrawn.Then, by the stretching, extension of cylinder 48, make machinery change mode of operation (Fig. 3,4) over to from non-operating state.At this moment, under hydraulic cylinder 40 effects, curved surface chassis 30 promotes built on stilts, as shown in Figure 3.Laterally drive 47 runnings are traversing to needing punching press above the ground with punching machine 12, and hydraulic cylinder 40 actions then prop up the chassis to fill up 28 closely to contact with soil surface.As shown in Figure 4, thus hydraulic cylinder 40 action reduction channel bar 24 and the chassis overhang 28 that links to each other with casing 22.
The power that acts on soil surface is to prop up pad and 28 realize that the chassis is propped up pad and then the punching press energy reached the face of land by 34 reciprocal lifting and the following drop impact chassis on channel bar 24 of dropping hammer.In each motion cycle, hydraulic cylinder 36 can be with the jack-up of dropping hammer by body structure, and when dropping hammer 34 when rising to predetermined altitude, hydraulic cylinder 36 pressure releases are dropped hammer and 34 fallen after rise voluntarily and impact the chassis and prop up pad 28.
Each motion cycle height that is promoted that drops hammer is determined through choice of practice.Drop hammer and quicken in the dropping process, the potential energy that lifting process is put aside changes kinetic energy into, produces impact force action in soil surface.
Relevant parameters is determined successively according to the soil condition at compacting scene.In fact, drop hammer 34 reciprocal lifting and fall after rise and be control automatically.As Fig. 5, the suitable height that sensor 23, the device that is similar to switch or perhaps ultrasonic sensor, these control device are installed on channel bar 24 drops hammer with induction and is promoted to selected height.Sensor 23 is placed on the channel bar 24, can transfer up and down easily, so that the hoisting depth that control is dropped hammer meets soil condition.After the soil compression of 30 belows, curved surface chassis reached suitable standard, the punching press of this moment was promptly finished.If need, can open driver part shifted laterally punching machine 12 again to the adjacent soil surface, carry out punching operation afterwards.
Clearly, make the band compacting partly of carrier loader back become possibility by the shifted laterally of punching machine.If needing the part of compacting is the place ahead of a contiguous band of having pressed or the other direction of carrier loader, can move forward carrier loader or carrier loader turns to compacting, compaction part is joined together.
Hammering blow type impacting machinery 10 is applicable to compacting small size location, one of main application of this equipment is compacting and the abutment location of part in succession, all above-mentioned characteristic descriptions about the dropping-weight compactor structure show this system for compacting can the compacting abutment the long and narrow location of part in succession.In addition, the compaction effort of this mechanism vertically acts on does not have cross component force on the ground so that influences the abutment structure.
Another important application of hammering blow type impacting machinery is to utilize the shifted laterally compacting band location of punching machine 12 in the maintaining work of highway, and needn't mobile carrier loader.Other application comprises the compacting engineering of long and narrow relatively irrigation canals and ditches, uses this machinery and need not mobile carrier loader, utilizes the shifted laterally of punching machine 12 to get final product.
Although only mention and use carrier loader, as draw-gear,, also can draw this compacting machinary 10 with Motorized traction devices such as other trucies, also be included in the scope of the present invention.Equally, although only mention that punching machine 12 is installed on the carrier loader back and operates, carry out compacting operation also for this reason within the scope of invention with this side of inferring that punching machine is installed on carrier loader.
In view of the concrete enforcement of said process mostly by manual control, but automatic control system also is within the invention scope.For example, control is finished by PLC (program logic controller), edits this controller in advance concrete compaction procedure is set.For instance, according to soil property and desired compaction, edit PLC in advance and will produce a series of impact forces at corresponding high level place, at this energy level place, dropping hammer is producing impact force than low-lying level then from the corresponding height falling.Selecting PLC control can be that high energy impact events power and low energy impacts power replace mutually.Exchange process is deposited the impact force of each energy level generation and is controlled by PLC each time.
The variation of multiple alternate manner also is classified as within this invention.As substituting illustrated curved surface chassis 30 with plane bottom plate, the alternative sprocket wheel of any side direction drive unit drives these punching machine 12 lateral slidings and all is classified as within the present invention.
