Background technology
Through known this type of soil compression device of prior art.They are provided with usually by this way: through the drive unit in the rammer superstructure, can drive the rammer pin, the particularly tamping plate axial vibration that are arranged on the substructure, thereby the pulse of compacting load is introduced in the subsoil.
Motor is connected with the rammer pin through eccentric driving device usually, and simultaneously, this eccentric driving device functionally is connected with transmission component, and transmission component converts the mechanical power of motor into transmission component and the axially-movable of the rammer pin that links to each other with transmission component.
For the rammer pin can freely be moved axially, the spring assembly of guide cylinder is set at the free end that is arranged in the substructure zone of connecting rod usually, this spring assembly makes that ramming pin can carry out axial vibration.
Through United States Patent(USP) No. 3090286 known such vibration rammers.This rammer comprises motor, and the rotating output shaft of motor is provided with eccentric gear.This eccentric gear is connected with slider-operated property ground by means of connecting rod, thereby can convert rotatablely moving of motor into connecting rod move axially, and therefore converts moving axially of the whole transmission component that vibrates rammer into.
This connecting rod comprises and is positioned at its free-ended guide piston.Through the piston guide part in the bottom guide cylinder that is under the jurisdiction of substructure, this guide piston can reciprocally move axially.Should be axially with compacting operation during compaction movement corresponding.The spring assembly of being made up of one or several springs is arranged on the both sides of piston guide part vertically, and its medi-spring is supported respectively against latch plate, and said latch plate is fixed on the guide cylinder of bottom on it deviates from the side of piston guide part.This bottom guide cylinder joins in the level and smooth slideway in the guide cylinder of top, and this top guide cylinder is rigidly connected with the shell of vibration rammer.
In compacting operation; This bottom guide cylinder of the driving of the transmission component that is vibrated moves on axial direction with rammer pin that is attached thereto or tamping plate together, and the maximum compacting amplitude in this compacting operation is confirmed by the relative play of employed spring assembly, top and bottom guide cylinder, the factors such as size of eccentric driving device.Thereby obtain to have the vibration rammer that good compactibility can and have sufficient size.
Yet for example the process that unloads from truck, the total weight of vibration rammer may all drop on and ram on the pin.Consequently cause substructure or ram pin and move, as that kind that also can take place when the compacting operation towards superstructure.Momentum according to falling, following situation may take place: the motion amplitude that the relative superstructure of substructure produces is greater than the motion amplitude under the normal compacting operation situation.In the case, the energy of whereabouts will import geared system or drive unit into through the transmission component of vibration rammer.This may cause serious damage.
Therefore, the structure of the gear-bearing of vibration rammer well known in the prior art has very large size.This has negative effect for the weight of machine and the distribution of weight of entire machine.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of vibration rammer above-mentioned, the weight of its structure is lighter, cost efficiency is higher, particularly in transportation, more can prevent to damage.
This purpose realizes that through a kind of soil compression device, particularly a kind of vibration rammer it comprises substructure and superstructure; Said substructure has the pin of rammer and is arranged at the bottom guide cylinder on the said rammer pin; Said superstructure has shell, is arranged at top guide cylinder and at least one drive unit on the said shell; Said drive unit functionally is connected with rammer pin in the said substructure through transmission component, makes said rammer pin to move with respect to superstructure with at least one compacting amplitude along at least one compacting axis; Said top guide cylinder and said bottom guide cylinder can be relative to each other through forming at least one axially directed assembly move along the direction of said compacting axis; Wherein, Between said superstructure and said substructure, be provided with at least one backstopping assembly; When substructure was about to exceed maximum compacting amplitude with respect to superstructure mobile, this backstopping assembly will backstop substructure moving with respect to superstructure.
" guide cylinder " in the scope of the invention is to be understood that any component for can be used for leading between superstructure and the substructure and/or be arranged on the guiding of the inner transmission component (connecting rod that particularly has spring base or spring assembly) of guide cylinder.This means that guide cylinder not only can have the geometry of tube, also can be any other shape.In this respect, " amplitude " is to be understood that to driving any maximum amount of movement or the maximum offset that on the compacting axis direction, produces in the process of ramming pin at eccentric driving device.
According to the present invention; This backstopping assembly relates to a kind of like this parts: in the process that superstructure and substructure relatively move; In case this relatively move with the compacting operation process in situation compare and have bigger amplitude; Maybe when this amplitude that moves during greater than so-called " maximum compacting amplitude ", these parts act on freedom of motion with restrictive mode.
In the case, " compacting amplitude " is to be understood that two peak excursions relative to each other realizing for process middle and upper part structure and the substructure that refers in fact at compacting operation.Therefore, if ram pin in the process of compacting operation with respect to superstructure outwards with to internal vibration, the compacting amplitude then is equivalent to fully inside vibrational state and fully outside distance half the between the vibrational state, the value that promptly passes through half the.
In case surpass this compacting amplitude---for example because the rammer underfooting of vibration rammer fall to the ground---its mean that ramming pin moves the amplitude that has usually when having exceeded compacting operation towards superstructure; Backstopping assembly between superstructure and the substructure will work; Thereby will stop substructure with respect to the moving of superstructure, particularly will prevent that said whereabouts from causing, through the transmission of transmission component to the power of drive unit.
Backstopping assembly will stop this situation that relatively moves between superstructure and the substructure within scope of the present invention, will be called " stop " situation.
Carry out because the load under the stop situation dissipates can not wait through transmission component, so parts such as transmission component and geared parts can be set to have less size, this means that the weight of this machine will advantageously reduce.
More than use and also be applicable to such embodiment: should prevent the corresponding excessive spring skew of the relative superstructure of substructure in this embodiment.In the case, also can use backstopping assembly to prevent this point.
This backstopping assembly and two guide cylinders that can move relative to each other are preferably with this form setting: only when the normal compacting amplitude that occurs in the compacting operation process exceeds a safety value, and the situation of appearance " stop ".Therefore, if substructure moves compared to the compacting amplitude of superstructure with for example 20cm, this backstopping assembly will preferably begin to work when " stopping amplitude " will be greater than 30cm so.Therefore, this is illustrated in this case, and substructure can move towards the maximum value of superstructure with 30cm, and backstopping assembly will stop this and move then, has therefore reached maximum compacting amplitude.
An advantageous embodiment relates to the geometry of soil compression device, and this soil compression device comprises structure and is set to the backstopping assembly of this form: when being about to exceed maximum compacting amplitude, said backstopping assembly is extruded against shell and/or top guide cylinder.The load (for example when the rammer pin of vibration rammer falls to the ground) that imports into through the bottom guide cylinder will dissipate through top guide cylinder and/or shell by this way, and can not cause damage to drive unit, transmission component and geared system.
