Novel distributing machine for bridge deck concrete pavement

Abstract

The invention discloses a novel distributing machine for bridge deck concrete pavement, which is characterized in that the machine comprises protective walls arranged on the two sides of a terrace, and I-shaped guide rails are arranged on the upper end faces of the protective walls; a trolley with rollers is arranged on the guide rails in a matching manner; a material cavity is formed in the innersides of the protective walls; a packing auger is arranged in the material cavity, the two ends of the packing auger penetrate through two side plates a respectively and are provided with bearings with rhombic seats, and the packing auger is connected with a motor shaft through chains arranged on a driving chain wheel and a driven chain wheel; a sliding rail is arranged above the material cavity,and a blanking hopper with walking wheels is arranged on the sliding rail; a vibrator is arranged outside a side plate b; and a flattening template is arranged at the bottom of the material cavity. The machine is compact in structure and good in stability, material distribution, compaction and leveling are integrated, the operation is easy, the labor intensity of workers is greatly reduced, timeis saved, the working efficiency is improved, and the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the field of distributing machines, in particular to a novel distributing machine for bridge deck concrete laying. Background technique [0002] In recent years, expressways have rapidly extended to mountainous areas with complex terrain and geological conditions, and bridges account for an increasing proportion of the total length of the route. At the same time, the traffic flow and overloaded vehicles continue to increase, and the weather conditions are very harsh. Therefore, the cement concrete bridge deck pavement that directly bears the wheel load is facing a severe test; the requirements for concrete pavement equipment are also getting higher and higher; the traditional concrete placing machine has the phenomenon of uneven distribution at the edge and insufficient compaction. It directly affects the construction quality and reduces the service life of the bridge deck; therefore, it is particularly important to design a ne...

Therefore, the cement concrete bridge deck pavement that directly bears the wheel load is facing a severe test; the requirements for concrete pavement equipment are also getting higher and higher; the traditional concrete placing machine has the phenomenon of uneven distribution at the edge and insufficient compaction. It directly affects the construction quality and reduces the service life of the bridge deck; therefore, it is particularly important to design a new type of concrete placing machine; it is of great significance to improve the quality of concrete bridge deck pavement and prolong the service life of bridge structures
