Description

Road maintenance vehicle

The utility model belongs to E01C class technology, particularly relates to a kind of road-maintaining truck.

In known road maintenance, shop, the bituminous concrete beach of being adopted machine, because this body structure is limit, also have following deficiency: the first speed of service is slow, it two is this machine road maintenances when not being suitable for construction point dispersion when the road maintenance; It three is that this machine adopts the road materials scope little.

The purpose of this utility model is to overcome the deficiency in the known technology and a kind of material spreader extensive and different kinds of roads maintenance and fast road-maintaining truck of the speed of service of being applicable to is provided.

The purpose of this utility model is achieved in that

On two crossbeams between railway carriage in main frame of the present utility model and the driver's cabin maincenter oil cylinder is installed respectively, by hinge insulation cover is installed on the railway carriage, baffle plate and suspension hook are installed by screw in the railway carriage rear end, the feed bin that has screed and ironing oil cylinder by suspension hook hook dress, front bottom end at feed bin is also installed two support wheels by rotating shaft, the above-mentioned maincenter oil cylinder hinged big arm of bearing pin, the other end of big arm fixedly is equipped with feed bin, the feed bin oil cylinder is housed on its feed bin, and the lower end of feed bin oil cylinder is fixed on the support on the crossbeam; The front spring spring that has propons respectively near the crossbeam of two front-wheels of main frame by and the installation of end overlap joint hinged with its two fixing fixed block one ends, with bearing pin the propons oil cylinder fixedly is housed by screw on the fixed block on the crossbeam, the other end of propons oil cylinder is fixed on the fixed block of fixing with propons by bearing pin; The rear spring that has back axle respectively near the crossbeam of two trailing wheels of main frame by and the installation of end overlap joint hinged with its two fixing fixed block one ends, on rear spring, also be fixed with overload spring by screw, with bearing pin the back axle oil cylinder fixedly is housed by screw on the fixed block on the crossbeam, the other end of back axle oil cylinder is fixed on the fixed block of fixing with back axle by bearing pin.

Dual-side at feed bin of the present utility model has the side mouth, and the luffing plate is installed in the bottom, both sides in the feed bin.

On the suspension hook position of installing of big arm of the present utility model, install suspension ring corresponding to the railway carriage rear end.

Advantage and the good effect that the utlity model has are:

1. the utility model speed of service is fast, the road maintenance and the maintenance of a dispersion that is specially adapted to construct.

2. because the screed that can make the mechanization of shop layer is housed the feed bin rear end in the utility model and the feed bin front bottom end by rotating shaft two support wheels has been installed and its bottom surface is a plane, then can make the screed equilibrant force good and make the pavement quality that paves might as well and can make the road materials scope of the utility model employing wide.

3. utilization is loaded on the luffing plate in the feed bin, and the spoke face width degree of paving concrete pavement is changed between 1～2.3 meter as required, so the utility model is specially adapted to because of the recovery of the road behind road damage and the pipeline construction and paves.

4. consider maintenance, maintenance road construction point is many and reaches the long characteristics of each construction point spacing distance less with material, few in order to guarantee road materials in long time interior heat amount loss, then on railway carriage of the present utility model, movable heat insulation cover is installed.

5. propons oil cylinder that in the utility model, installs additional and back axle oil cylinder, more steady when guaranteeing its paving concrete pavement.

The utility model has following accompanying drawing;
