Extrusion forming device for traffic engineering highway construction

WANG LI

The invention provides an extrusion forming device for traffic engineering highway construction, belongs to the technical field of extrusion forming devices, and aims at solving the problem that when an extrusion roller in an existing hand-held extrusion forming device is disassembled, due to the fact that a large number of bolts need to be screwed off through a tool, the disassembly convenience of the extrusion roller is greatly reduced. The extrusion forming device comprises a base, wherein the base is a rectangular plate-shaped structure; two supporting columns are arranged on the bottom end face of the base in a bilateral symmetry mode; the lower ends of the two supporting columns are each fixedly provided with a bearing seat; and an extrusion roller is rotationally connected between the two bearing seats. When the extrusion roller is disassembled, fastening bolts are screwed off, then bearing seat covers are rotated downwards to be opened, the bearings on the rotating shafts lose the limiting effect in the bearing seats and the half circular grooves in the bearing seat covers, then the extrusion roller is disassembled from the two bearing seats, and in the whole disassembling process, due to the fact that a large number of bolts do not need to be disassembled, the disassembly convenience of the extrusion roller is greatly improved.

本发明提供一种交通工程公路施工挤压成型装置，属于挤压成型装置技术领域，以解决现有手扶式挤压成型装置中挤压滚筒在拆卸时，由于需要通过工具拧下大量螺栓，进而大大降低了挤压滚筒拆卸时的便捷性的问题，包括:底座；所述底座为矩形板状结构，且底座底端面呈左右对称状设有两个支撑柱，两个支撑柱下端均固定安装有一个轴承座，且两个轴承座之间转动连接有挤压滚筒。挤压滚筒在拆卸时，将紧固螺栓拧下，然后将轴承座盖向下转动打开，使转动轴上轴承在轴承座和轴承座盖上二分之一圆形凹槽内失去限位作用，然后将挤压滚筒从两个轴承座上拆下即可，整个拆卸过程，由于无需拆卸大量螺栓，进而大大提高了挤压滚筒拆卸时的便捷性。
