Abstract
The utility model provides a double-vibration high-strength rolling plate of paver, mainly used for paving and compacting the various materials which are used for building the freeway. The front line concrete vibrating beam(5) and the back line concrete vibrating beam(6) which are in the front of the double-vibration high-strength rolling plate of paver have two impacts and initial compactions to the mixture, and the concrete vibrating distances of the front line concrete vibrating beam(5) and the back line concrete vibrating beam(6) are capable of being adjusted. The utility model has the advantages of high degree of pre-compaction, good evenness of the compaction degree and high planeness, etc.
Description
The utility model provides the two height that vibrate of a kind of paver to suppress screed, is mainly used in the compacting that paves of the various materials of building highway.
Paver is the necessary key equipment of making high-grade highway.Screed is as the equipment of paver, and its service behaviour has solved the quality of paving concrete pavement.At present, international and domestic in paver industry screed structure commonly used, as: the paver screed that VOGELE company produces by singly vibrate+two compactings form.Form by two vibrating+off-centre vibration as the paver screed that ABG company produces.The shortcoming of these two kinds of products is that the stabilizing material compactness that paves is not enough for the former, and that the latter is the asphalt surface finish that paves is not enough.
The purpose of this utility model provides a kind of two height that vibrates and suppresses screed, promptly utilizes send as an envoy to compactness, the planeness of paving concrete pavement of two vibrating+pulse vibratory compaction principle design can both satisfy construction requirement, to overcome the deficiency of prior art.
The utility model is with following technical scheme: the front row vibrate beam (5) and back row vibrate beam (6) by Bolt Connection on connecting rod (3), connecting rod is equipped with bearing on (3), eccentric shaft (1) is housed in the bearing, eccentric shaft is equipped with the another one bearing on (1), and this bearing is contained in the supporting (4), and supporting (4) is by being bolted on the screed; Several pulse cylinders (7) all are housed on compacting beam (9), and compacting beam (9) produces the dither of 67-71Hz under the effect of pulse cylinder (7).
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing 1 is suppressed the screed structural representation for two height that vibrate;
Shown in the figure, (1) eccentric shaft, (2) excentric sleeve, (3) connecting rod, (4) supporting, (5) front row beam that vibrates, (6) back row beam that vibrates, (7) pulse cylinder, (8) pre-compressed spring, (9) compacting beam.
Its course of work principle is as follows: two twice ballistic motion of vibrating are that the rotation by eccentric shaft (1) drives vibrate beam (5), (6) motion of forward and backward row and realizes, the rotation of eccentric shaft (1) is by fluid motor-driven, can make the frequency stepless adjustment between 0-1450r/min of vibrating like this; The vibrate stroke that vibrates of beam of forward and backward row can multistagely be adjusted, thereby has realized that the forward and backward two rows beam that vibrates carries out the shock compaction of twice 0-27Hz to the compound that paves.Several pulse cylinders (7) all are housed on compacting beam (9), and compacting beam (9) produces the dither of 67-71Hz under the effect of pulse cylinder (7).Vibration force is passed to material spreader, to reach comparatively desirable compactness and smooth requirement.The pulse cylinder piston acts directly on compacting beam (9) on the paving layer, and their compactings all the time guarantee the surperficial planeness requirement that paves on the paving layer surface.The generation of pulse oil pressure is by an impulse generator, and the size of pulse frequency is by the decision of impulse generator rotating speed, and impulse generator is by a fluid motor-driven, and its rotating speed is stepless adjustable.Pulse vibratory compaction base reason is to use Newton's second law F=ma, because compacting vibration of beam frequency is quite high, so its acceleration a is quite big, so pressure=(compacting beam quality * acceleration) to the active force of compound than it from important much bigger, can guarantee the whole degree of highly dense solidity peace on road surface, back that paves, so be particularly suitable for construction by making super highwaies such as pitch mixed materials.
The utility model has the advantage of: two vibrating carried out the shock compaction of twice 0-27Hz, tool by two row's vibrating beams to the compound that paves Pre-compacted packing height is arranged, packing good uniformity, flatness advantages of higher, the two-ash broken stones that is particularly suitable for paving, RCC, stable The base fixed materials such as composite soil.
Claims (4)
1, the two height that vibrate of a kind of paver are suppressed screed and are made up of eccentric shaft (1), excentric sleeve (2), connecting rod (3), supporting (4), front row the vibrate beam (6), pulse cylinder (7), compacting beam (9) of beam (5), back row that vibrate, it is characterized by the front row vibrate beam (5) and after arrange the beam (6) that vibrates by Bolt Connection on connecting rod (3).
2, two height that vibrates according to claim 1 is suppressed screed, and it is characterized in that: connecting rod is equipped with bearing on (3), and eccentric shaft (1) is housed in the bearing.
3, two height that vibrates according to claim 1 is suppressed screed, and it is characterized in that: eccentric shaft is equipped with another bearing on (1), and this bearing is contained in the supporting (4), and supporting (4) is by being bolted on the screed.
4, two height that vibrates according to claim 1 is suppressed screed, it is characterized in that: several pulse cylinders (7) all are housed on the compacting beam (9).
