Description

Spreading machine edge telescopic ironing device
Technical Field
The utility model belongs to the technical field of paver screed plates, and particularly relates to a paver side telescopic screed device.
Background
The asphalt concrete paver is a special machine for paving asphalt pavement or stabilizing base material, and the asphalt concrete or stabilizing material is coated on the pavement according to the requirements of the width, camber, thickness, flatness and compactness of the pavement. The screed is one of the main working devices of asphalt concrete paver, which shapes, tamps and screeds asphalt mixture spread by a screw conveyor according to the width, thickness and camber required by highway construction, and the whole screed forms a set of hanging devices, and the screed is in a floating state on the paving layer during working. With the development of pavement machinery and the improvement of pavement construction technology, the screed of the paver is also developed in a long-standing way so as to meet the pavement construction requirements. The early ironing board is fixed, the ironing board is rigidly connected with the machine body, the moving track of the ironing board moves along with the machine body, the self-leveling effect is poor, the later floating ironing board is developed, the ironing board can move relative to the machine frame, the original moving state can be kept during the paving operation, and the floating ironing board has a better leveling effect.
The screed is divided into a mechanically widening screed and a hydraulically telescoping screed in an extension manner. The large-scale and ultra-large-scale pavers mostly adopt a mechanically widened ironing plate, wherein the mechanically widened ironing plate mechanically assembles a basic ironing plate and a widened ironing plate by bolts into the operation width required by construction, and the mechanically widened ironing plate has the advantages of simple structure, better integral rigidity and uniform cloth distribution by penetrating a whole paving groove through a material distributing spiral. The hydraulic telescopic screed plate is telescopic by a hydraulic cylinder, the paving width of the hydraulic telescopic screed plate is adjusted steplessly, the adjustment is convenient, the superiority of the hydraulic telescopic screed plate is more displayed in construction with variable paving width, but the integral rigidity is poorer than the mechanical widening, and a material distributing screw cannot penetrate through the whole paving groove, so that the paving quality is possibly influenced due to uneven concrete material distribution.
With the market demand of technological development, edge-stretching screeds have emerged. The utility model patent No. 2015205400617 discloses a mechanically widened edge telescopic screed comprising a fixed screed and a telescopic screed. The mechanical widening screed plate and the side telescopic screed plate are matched for use, so that good rigidity of the original mechanical widening screed plate is reserved, and flexible characteristics of the hydraulic telescopic screed plate are also considered. There are also some disadvantages: (1) The universality is not strong, and because the screed plate needs to be fixed and connected with the mechanically widened screed plate, the width, the height and the connecting holes of the screed plates of different manufacturers, particularly the central positions of the vibrating shaft and the vibrating shaft are not completely the same, so that the matching property is limited; (2) The structure redundancy, the fixed screed plate and the telescopic screed plate respectively comprise a vibration and vibration mechanism, the main function of the fixed screed plate is to support and connect the telescopic screed plate and the mechanically widened screed plate, and the frame structure is identical to that of the traditional mechanically widened screed plate, so that the structure is redundant, and the space can be simplified greatly; (3) The whole weight is too large, the installation and the disassembly are inconvenient, and the whole weight is too heavy because the width of the fixed screed plate is 500-1000 mm and the fixed screed plate is provided with the screed plate frame, the vibrating mechanism and the like; (4) The heating and ignition of the fixed screed plate are inconvenient, and the heating and ignition of the fixed screed plate generally requires the telescopic screed plate to extend out to expose the ignition port due to the shielding of the box body structure on the fixed screed plate and the telescopic screed plate, which is troublesome.
