Embodiment 1

[0038] Embodiment 1: casting type asphalt paver, such as figure 1 As shown, a power unit 1, a traveling unit 2 and a cloth unit 3 are included. The distribution device 3 includes a support 4 , a rail assembly 5 and a distribution scraper 6 . The running device 2 is arranged at both ends of the support 4 , the power unit 1 is arranged at both ends of the support 4 , and the power unit 1 is fixedly connected with the support 4 . The guide rail assembly 5 is arranged on the top of the bracket 4 . The cloth scraper 6 is arranged on the guide rail assembly 5 and can slide along the guide rail assembly 5 .

[0039] The rail assembly 5 comprises several rail segments 7 . Any guide rail segment 7 includes a guide rail body 8 , and a rack 9 is arranged below the guide rail body 8 .

[0040] Such as figure 2 , 3 As shown, the interior of the guide rail body 8 is hollow, and a sub-connection seat 10 is provided at one end thereof, and a female connection seat 11 is provided at the...

Embodiment 2

[0047] Embodiment 2: pouring type asphalt paver and distributing device 3 thereof, the difference with embodiment 1 is, as Figure 4 As shown, the driving gear 24 and the driven gear 18 are both herringbone gears, which improves the meshing degree between the driving gear 24 and the driven gear 18, reduces the axial load, improves the carrying capacity, and makes the work more stable.

Abstract

The invention relates to the field of road pavement construction equipment, and especially relates to a pouring type asphalt paver and a material distributing device thereof. The pouring type asphaltpaver is characterized by comprising a support, a guide rail assembly and a material distributing scraper blade, wherein the guide rail assembly comprises a plurality of guide rail sections, any guiderail section comprises a guide rail body, a rack is arranged under each guide rail body, a son connection seat is arranged at one end of each guide rail body, a mother connection seat is arranged atthe other end of each guide rail body, a plurality of first threaded holes are formed in an end face of each son connection seat, each mother connection seat comprises an end plate, a plurality of second threaded holes are formed in each end plate, each mother connection seat is further provided with a driving gear and a plurality of driven gears, the driving gear is arranged on the inner side ofthe end plate, the plurality of the driven gears are arranged to correspond to the second threaded holes and are in matched connection with the driving gear, and bolts are arranged in inner holes of the driven gears. The pouring type asphalt paver has the advantages of convenience in assembling and disassembling and no effect on movement of the material distributing mechanism.

Description

technical field [0001] The invention relates to the field of road pavement construction equipment, in particular to a castable asphalt paver and a material distributing device thereof. Background technique [0002] Pourable asphalt concrete belongs to suspension dense mixed asphalt concrete, which has the characteristics of dense impermeability, good durability, excellent viscous toughness, strong adaptability to change, and good followability with the deformation of steel bridge deck, so it is especially suitable for large Medium-sized bridges, especially long-span steel bridge deck pavement. On the guide rails of the existing pouring asphalt paver, built-in flanges and bolts are usually used to connect adjacent guide rail segments. The bolts and flanges are enclosed inside the guide rail segments. During disassembly or connection, The extended casing wrench is required to be disassembled and assembled in sequence, which brings great inconvenience to the assembly of the gu...
