The specific embodiment
Fig. 1 schematically shows the part of sliding formwork paver.The sliding formwork paver comprises pressure plare 12, and the width of its extend past sliding formwork paver is parallel to ground 14 and cross-section direct of travel 16 is arranged.Corresponding Height Adjustable sidewall (not shown) is arranged in the side of pressure plare 12.When seeing on direct of travel 16, a plurality of jolting devices 1 are arranged in the upstream of pressure plare 12.These jolting device 1 cross-section direct of travels are arranged continuously.Jolting device 1 immerses in the constructional materials that is made of concrete 20 or concrete mixture.Each jolting device 1 comprises housing 18, is arranged in vibration machine 19 and fastener 10 in the housing 18.Vibration machine 19 is operationally realized vibration when for example being driven by the Vidacare corp that combines with unbalance mass.Described unbalance mass, can be for example with 12, and 000rpm is rotated.The amplitude of this process is very low, and for example the free end at jolting device is ± 0.4mm.Thus, constructional materials will be liquefied and form required shape by pressure plare 12 subsequently.Jolting device 1 will utilize around the housing 18 approximately, and the effective diameter scope of 75cm makes constructional materials liquefaction.Jolting device 1 is arranged with such structure, is made that the vibration of adjacent jolting device is overlapped.Fastener 10 is used for the housing 18 of jolting device 1 is fastened on the pipe 25 that links to each other with the mechanical framework 2 of building machinery.Can be by the height of piston/cylinder unit adjustable pipe 25 with respect to mechanical framework 2.In addition, pipe 25 can prolong on width, makes it be suitable for the operation width thus.As alternative, fastener 10 can be connected on the pressure plare 12.Can not be passed on the mechanical framework 2 of building machinery in order to ensure the vibration that is produced by vibration machine 19, fastener 10 has a plurality of wind springs 8, and they have the slinky spring characteristic.Wind spring 8 comprises a plurality of spring windings separately.The elastic characteristic of wind spring 8 is suitable for the vibration of vibration machine 19, thereby prevents that basically or fully vibration machine 19 is to the building machinery transmitting vibrations.In operating process, the fastener 10 with wind spring 8 can partly immerse in the concrete 20.
In embodiment of the present utility model shown in Figure 1, comprise that separately the flexible member 22 of molded component is arranged on the wind spring 8.Molded component is suitable for the interior profile of each wind spring 8, thereby the gap between the spring winding is airtight to inside.The elastic characteristic of flexible member is suitable for the elastic characteristic of wind spring 8 as follows, promptly the elasticity of fastener 10 and damping characteristic not can or unsubstantiality ground variation only; Thereby, will continue to prevent basically or fully mechanical framework 2 transmitting vibrations of jolting device 1 to building machinery.Because the gap between the spring winding of wind spring 8 obtains filling, so wind spring 8 is subjected to the adhesion of particle, stone or the similar substance of coalescent concrete 20 on it no longer easily.
Figure 2 illustrates another embodiment.Each wind spring 8 has the flexible member of casting around it or is surrounded by flexible member, simultaneously the spring winding of flexible member complete closed wind spring 8.Cavity 38 is arranged in the inside of each wind spring 8, and it extends and at two distolateral openings of corresponding wind spring 8 along corresponding wind spring axis.Wind spring 8 is fastened to down on the mounting plate 24 by screw 26 and nut 28.Wind spring 8 last spring winding have the diameter littler than other spring winding of wind spring 8, and described last spring winding is clamped between the head and following mounting plate 24 of screw 26.Respective screws 26 is connected down the downside of mounting plate 24 by nut 28.Wind spring 8 was affected with being connected of upper platen 24, for example because make this last spring winding form eyelet-like opening in an opposite direction in corresponding last spring winding winding.Described last spring winding is clamped between the head and upper platen 24 of screw 30.Screw 30 is connected the upside of second mounting plate 26 by nut 32.
Fig. 3 a represents wind spring 8.Gap between the spring winding of wind spring 8 obtains airtight by means of tubular elastic element or molded component 22.Tubular elastic element 22 can reach several millimeters elastic material or film by thickness and make.Tubular elastic element 22 can be formed for example shrinkage hose in the capping wind spring outside.As alternative, can utilize bellows.Additional Elastic Cylindrical molded component 22 can be used in combination the inside that described shrinkage hose or bellows are used for wind spring 8.
In Fig. 3 b-3f, show the alternate embodiment of flexible member 22.Fig. 3 b represents that external diameter is equal to or slightly less than the hypostracum of wind spring 8 internal diameters.Fig. 3 c represents to have the wind spring 8 of molded component.Described molded component is suitable for the interior profile of wind spring 8 and forms to have the groove that is used to hold screw 26 heads.This embodiment has been described in the description of Fig. 1 in more detail.Fig. 3 d represents that external diameter is equal to or slightly less than the cylindrical molded component of wind spring 8 internal diameters.Described molded component comprises hexagonal socket that is suitable for screw head and the protuberance 22a that gives prominence in it.Alternatively, the molded component of Fig. 3 c molded component that can not have any groove and a Fig. 3 d can not have any protuberance.In this case, molded component can be arranged to abut against on the respective screws head of screw 26.
Fig. 3 e represents wind spring 8, and its medi-spring winding has the flexible member 22 of casting around it.This embodiment is illustrated in greater detail in the description of Fig. 2.Fig. 3 f represents the wind spring 8 by the outer shell sealing.Described outer shell has the internal diameter that equals or be slightly larger than wind spring 8 external diameters.
Figure 4 and 5 are respectively lateral view and the plan views that comprises the groups of springs 40 of four wind springs 8, and wind spring 8 has the flexible member 22 of casting around it.For described groups of springs 40 is fastened on the mounting plate, the spring winding on wind spring 8 respective end has been rotated relative direction, forms eyelet-like opening 44 thus.These eyelet-like openings 44 are arranged in the outside of elastomeric material 22.Utilize screw that the spring winding of these final eyelet-like is clamped between respective screws head and the corresponding adjacent mounting plate 24.Respectively at the corresponding opposite side of the mounting plate 24 and second mounting plate 26, by the nut stretching screw.
Fig. 6 is a view of seeing the lower shoe 24 shown in Fig. 1 from the below.Described lower shoe 24 comprises that diameter is greater than the distance A between two adjacent wind springs 8, the opening 46 of B.Therefore, the particle in the inner aperture is washed out once more by opening 46 between the wind spring 8 through also clamp-oning once in a while between wind spring 8.
Although the concrete illustrative embodiments of reference is described and is shown the utility model, and does not mean that the utility model is confined to those exemplary embodiments.It will be recognized by those skilled in the art under the prerequisite that does not break away from the utility model actual range that limits by following claim and can make multiple change and change.Therefore all the such changes and the change that fall in accessory claim and the equivalents scope thereof all fall in the utility model protection domain.
