Description
Technical field
The utility model relates to a kind of screed governor motion that is used for paver.In addition, the utility model also relates to a kind of paver with this screed governor motion.
Background technology
In the process that road is laid, use the road spreading machine that road is laid usually.In actual applications, the width on road surface might not be consistent with the width of the screed of road spreading machine.Therefore in paver, just need on basic screed, add a freely-moving mangle.Usually, basic screed and freely-moving mangle are that front and back are arranged, actual paving is that the existence at the screed elevation angle will cause the minimum limit of the two to be on the different positions, in order to guarantee the planeness of paving concrete pavement, and must be with the minimum limit Height Adjustment unanimity of the two.
In known systems, in order to regulate freely-moving mangle with respect to the height of basic screed and be provided with height adjustment mechanism, wherein, pair of brackets is installed on the basic screed, the casing of freely-moving mangle is provided with two place's boss, two screw rods penetrate into respectively in the corresponding installing hole of two boss, and screw rod in height is a fixed-site with respect to boss.Simultaneously be provided with perforation in support, this perforation is equipped with the internal thread that matches with the external screw thread of screw rod.Screw rod is screwed in the perforation, and locks this guiding mechanism in the end by fastening screw nut.Adjust if desired, then at first unclamp fastening screw nut, the square head of pulling screw rod with spanner moves up and down screw rod then, finishes highly adjusting thereby drive freely-moving mangle.Yet in the application of reality, because structure space is limited, adjusting screw(rod) is arranged on the inside of freely-moving mangle, does not also have effort-saving mechanism, the bad application of force that operates, very hard.The variation that adds the practice of construction condition can cause the variation at the elevation angle often, and for the planeness that guarantees the road surface needs the often height of adjusting freely-moving mangle, existing structure is far from suitable and frequently adjusts.
Summary of the invention
Therefore, the purpose of this utility model provides a kind of screed governor motion that is used for paver.By using such screed governor motion, can when simply the difference in height of the basic screed of paver and freely-moving mangle being adjusted, can also adjust the relative angle between them.
First purpose of the present utility model realizes that by a kind of screed governor motion wherein, screed comprises basic screed and the freely-moving mangle of arranging with basic screed front and back, and wherein, height adjustment mechanism comprises: support is fixed on the basic screed; Worm screw can be rotatably set on the support; Worm gear is arranged on the support and cooperates rotation with worm screw; The screw rod of fixedlying connected with worm gear, wherein, the screed height adjustment mechanism also comprises: connecting portion is connected between screw rod and the freely-moving mangle, connecting portion is connected with screw flight, and connecting portion is being connected in freely-moving mangle around the mode of first axle rotation.When regulating by this governor motion, the connecting portion that is arranged between screw rod and the freely-moving mangle can rotate with respect to first axle, so just can adjust the angle of freely-moving mangle with respect to basic screed, adapts to the variation of different road surfaces situation.
According to a preferred design scheme of the present utility model, connecting portion is connected in freely-moving mangle in the mode that is parallel to first axle and moves.So just can relatively be adjusted at the distance between basic screed and the freely-moving mangle, thus compensation processing and rigging error.
Preferably, freely-moving mangle is provided with a pair of lug, and connecting portion is installed in the installing hole of lug versatilely, and installing hole is circular, and connecting portion is cylindrical.Realize in this way connecting portion on the freely-moving mangle, the rotatablely moving and translational motion on first axle in lug just around first axle.
Propose in a preferred design scheme of the present utility model, worm gear is connected on the support by bearing.Preferably, bearing is the circular cone roller bearing.Such bearing can carry bigger load.
Propose according to a preferred design scheme of the present utility model, be fixedly connected with crank on the end of worm screw, crank is arranged on the rear portion of freely-moving mangle.Can handle governor motion effortlessly by crank, thereby adjust relative altitude between basic screed and the freely-moving mangle simply.
Preferably, respectively be provided with a screed governor motion respectively at the two ends of freely-moving mangle.These two governor motions can be regulated separately, adjust relative altitude between basic screed and the freely-moving mangle thereby can rotate crank as required.
Another purpose of the present utility model provides a kind of paver with screed guiding mechanism of the above-mentioned type.This paver can be adjusted the difference in height of basic screed and freely-moving mangle and the relative angle between them simply, effortlessly.
