Abstract
The utility model relates to an anti-bending tensioning device for an ironing plate of a paver. The utility model is characterized in that two sides of the front balance weight of the paver are respectively provided with removable fixed arms, the outer ends of two fixed arms are respectively hinged with tensioning oil cylinders and a steel wire rope is arranged among the other end of each of the tensioning oil cylinders and two sides of the ironing plate. An adjustable supporting arm is also arranged among the outer ends of two fixed arms and two ear plates of a walking device of the paver, so the stress condition of the ironing plate is improved. The pull of the tensioning oil cylinders for two sides of the ironing plate is more effective, and the bending resistance and deformability of the ironing plate are enlarged. In addition, the utility model also has the advantages of simple structure, easy manufacture and assembly.
Description
Technical field
The utility model relates to a kind of paver that is used for highway construction, especially a kind of paver screed bending resistance take-up device.
Background technology
Present continuous development along with the highway in China building cause, domestic primary highway arterial highway is constantly extended, is widened, and common paver width is narrow, can not adapt to the demand of existing market, therefore, domestic many engineering machinery producer has developed some large-scale pavers one after another.But the screed wider width of large-scale paver, the material that paves when paving operation can have an active force backward to screed, makes the flexural deformation backward of screed both sides, and the width of screed is big more, and metaboly is serious more.For fear of this distortion that causes because of the material effect, drawing cylinder and wire rope have been installed by most of producer between paver front end and screed, give active force forward of screed, though this structure has been alleviated the problem of the stress deformation of screed, but when the screed width is big, angle between drawing cylinder and the screed diminishes, and has reduced the forward pulling force of oil cylinder to screed, and screed is still occured bending and deformation.
Summary of the invention
The purpose of this utility model is to overcome the technical problem that exists in the known technology and a kind of reliable more, effective paver screed bending resistance take-up device that has is provided.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Paver screed bending resistance take-up device, be installed in the drawing cylinder of counterweight both sides before the paver by two front ends, and two wire rope that are connected two drawing cylinder rear ends and screed two side ends are formed, it is characterized in that: add a removable fixed arm respectively on the installed surface of counterweight both sides before described two drawing cylinders and the paver, between the counterweight both sides set bolt and packing ring are installed before the inner of each fixed arm and the paver, between the outer end of each fixed arm and each the drawing cylinder front end jointed shaft is installed, also is hinged with support arm between two otic placodes of the outer end of each fixed arm and paver running gear.
The utility model can also adopt following technical measures:
Described support arm two ends are shaped on the adjusting screw, be equipped with in each screw the outer end have respectively with fixed arm outer end hinge hole and with the screw rod of vehicle frame otic placode hinge hole.
Advantage and the good effect that the utlity model has are: owing to install fixed arm between the counterweight additional and between the otic placode of fixed arm outer end and paver running gear support arm is installed before drawing cylinder front end and paver, increased the angle between drawing cylinder and the screed, improved the force-bearing situation of screed, make drawing cylinder more effective to the pulling force of screed both sides, improved the counter-bending deformation ability of screed, in addition the utility model also have simple in structure, be easy to the advantage of making, installing.
Description of drawings
Fig. 1 is the utility model symmetry one side structure schematic diagram;
Fig. 2 is the whole stress schematic diagram of figure the utility model.
Among the figure: counterweight, 10 bearing pins, 11 carriages, 12 bearing pins, 13 wire rope, 14 screeds, 15 screw rods, 16 screw rods before 1 set bolt, 2 packing rings, 3 fixed arms, 4 drawing cylinders, 5 support arms, 6 bearing pins, 7 otic placodes, 8 running gears, 9.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the both sides of counterweight 9 are installed two fixed arms 3 respectively by set bolt 1 and packing ring 2 before paver, the outer end of two fixed arms is hinged with drawing cylinder 4 respectively by bearing pin 10, be separately installed with wire rope 13 between the other end of each drawing cylinder and screed 14 both sides, outer end at two fixed arms is hinged with support arm 5 by bearing pin 12, the other end of support arm is hinged on the otic placode 7 of paver running gear 8 by bearing pin 6, support arm also can be made adjustable, that is: the support arm two ends are shaped on screw, be equipped with in the screw of two ends the outer end have respectively with fixed arm outer end hinge hole and with the screw rod 15 of running gear otic placode hinge hole, 16, also be shaped on carriage 11 on the outer cylinder of support arm, make the direction of pull of drawing cylinder more approach vertical screed like this.With the screed side is the origin of coordinates, laterally is X, and vertical direction is Y, and dotted line is the component F that original drawing cylinder directly is fixed on the tensile force f on the preceding counterweight of paver
xAnd F
yState, solid line is the component F ' of the drawing cylinder tensile force f that is fixed on the fixed arm outer end
xAnd F
