Abstract
The utility model relates to a leveling beam which is used for controlling the smoothness of the asphalt paving layer of a road surface in highway mechanized construction. The utility model is composed of lever type cross beam, a front and a back reference beams, wherein the lever type cross beam is attached to the wall side of a main frame of a paver and is positioned above an ironing plate of the main frame; the front and the back reference beams are respectively connected with lower parts of the front and the back ends of the cross beam and are arranged in front of and behind the ironing plate of the main frame. The beam body of the leveling beam is bridged over the space above the ironing plate of the paver instead of being installed on the outmost side of the paver, so the leveling beam is favorable for increasing the precision of the leveling control of a road surface. The front and the back reference beams can realize the independent control of the smoothness on both sides in front of and behind the main frame.
Description
The utility model belongs to the road building machinery technical field, relates to the average beam that is used to control pavement asphalt paving layer planeness in a kind of highway machinery construction.
In the highway machinery construction, the planeness on bitumen layer road surface is a very important index of checking and accepting highway construction, and for this reason, general all supporting on all kinds of senior pavers have a system that is used for controlling the paving layer planeness specially, is referred to as automatic horizontal control system.The use of automatic horizontal control system must have a benchmark that is independent of paver self, in the prior art, draws the mode of steel wire to do the leveling benchmark on roadbed except that adopting, and paver typically uses the average beam of outboard as automatic leveling benchmark.Because China promotes the method that view picture paves in the laying of Expressway Construction medium pitch layer, the average girder construction of traditional outboard just has very big inadaptability in practical application, it mainly shows as: one, because the average beam of traditional structure is provided in a side of the outside that the parts that form paving layer are paver main frame screed, it only can travel at the fringe region of road, and the general ground error in this zone is very big, therefore is difficult to control the planeness of view picture paving concrete pavement; Two, according to the operating principle of average beam, the length of beam is directly proportional with the precision of road surface leveling control, but the old-fashioned average beam of tradition is because of the length that limits its whole beam body of structure short (general not above 6 meters), thereby its leveling precision is corresponding just lower; Three, the beam body of the old-fashioned average girder construction of tradition is to be positioned at behind the paver screed to a side setting, be difficult to realize to before and after the main frame to the independent control of both sides planeness; Four, the average beam of traditional structure all is to adopt the steel slide plate to slide on roadbed or paving layer to travel, because the cementation of pitch causes performances such as its slip, turning not smooth, and easily brings the active force of distortion for total.
The purpose of this utility model is to overcome the deficiencies in the prior art, and then a kind of average beam of asphalt paver great-leap-forward that is suitable for the view picture paving operation and can improves the paving layer planeness is provided.
Be used to realize that the technical solution of foregoing invention purpose is such: change the average beam of traditional outboard into great-leap-forward average beam and with this new benchmark as automatic horizontal control system, in paver main frame wall side and be positioned at the lever cross coupling of main frame screed top and connect the forward and backward datum line beam that is contained in bottom, cross coupling rear and front end respectively and constitute, said forward and backward datum line beam lays respectively at the place ahead and the rear of main frame screed to the average beam of this great-leap-forward by attaching.
Compared with prior art, the utility model has been broken through way in the past, average beam crossed over from the screed sky of paver in the past but not be installed in the outermost of paver, the beam body just will travel on the good basis of road zone line planeness when host work like this, greatly reduce the influence of road areas at both sides ground error; New-type average beam respectively has a datum line beam to both sides before and after main frame, an one datum line beam is located at before the screed, the ground error can be cut to 1/12, another datum line beam is located at after the screed and travels on the road surface of just having spread, made full use of and just completed the not good characteristics of compacting surface evenness, so just realized controlling to the independent of both sides planeness before and after the main frame; After adopting great-leap-forward beam design scheme, whole beam body length reaches 18 meters, can improve the precision of road surface leveling control largely; In addition, the mechanism that screed is crossed on datum line beam top adopts the lever cross coupling, it has played the effect that front and back two parts datum line beam is linked to be a benchmark on the one hand, and the error information that machine, roadbed can be brought is on the other hand amplified, the sensitivity that has improved the leveling system detecting instrument.
Below with reference to accompanying drawing the utility model content is described further.
Fig. 1 is the lateral view of a specific embodiment structure of the utility model.
Fig. 2 is the schematic diagram of the supporting structure of average beam of this great-leap-forward and paver main frame, and dotted portion is a main machine structure among the figure, and solid line partly is average girder construction.
Fig. 3 overlooks to schematic diagram for Fig. 2 structure.
Fig. 4 is preceding datum line beam structural representation.
Fig. 5 is a back datum line beam structural representation.
As shown in the figure, the average beam of asphalt paver great-leap-forward described in the utility model is made of lever cross coupling 4, preceding datum line beam 2 and back datum line beam 6 three parts that manufacturing materials is big thick aluminium section bar (as YQ150A-01B aluminium extruded sections, YQ11001 aluminium extruded sections, YTG210 aluminium extruded sections etc.), 4 of lever cross couplings are located at the top of paver screed 5 and are connected with paver main frame 1 by many adjustable links 7, in the practical application, by the setting of these adjustable levers 7, can make this average girder construction be applicable to multiple paver type; Preceding datum line beam 2 and back datum line beam 6 connect the bottom that is contained in cross coupling 4 forward and backward two ends respectively by reference point connecting rod 3,8 separately, and wherein datum line beam 2 is positioned at the place ahead of main frame screed 5, and back datum line beam 6 is positioned at the rear of main frame screed 5.In addition, in view of the error filtration mechanism of in the past average beam all adopts lever geometry so that its to exist precision to be difficult for the defective that improves, forward and backward datum line beam 2,6 structures of the present utility model have adopted unique spring buffer formula mechanical structure, its design form is distinguished as shown in Figure 4 and Figure 5: preceding datum line beam 2 is spring buffer formula piston shoes beams, it has a beam column 21 anyhow, this anyhow beam column 21 times distribute to connect by cocking lever 23 and hinge knee 24 many piston shoes bars 22 be housed; Back datum line beam 6 is the wheeled beam of spring buffer, and it has a beam column 61 anyhow, this anyhow beam column 61 times distribute to connect by cocking lever 63 and hinge knee 64 many rollers 62 be housed.In the practical structures, the roller of being adorned on the datum line beam 6 of back 62 is hollow on-inflatable oil resistant rubber wheel, like this when the operation work of paver scene, thereafter datum line beam 6 will travel on roadbed or paving layer in the mode of rubber wheel pure rolling, than the mode that the average beam of traditional structure slides and travels on roadbed or paving layer with the steel slide plate, it travels and turn performance etc. all is significantly improved.
Other sequence number that marks in the accompanying drawing is respectively: 9---oblique adjustable connecting-rod; 10---detector; 11---haulage gear.
