Abstract

The invention particularly relates to a concrete pouring device for cast-in-place ballastless track bed construction, and solves the problems of low construction precision and increased construction cost in application of an existing conventional equipment and manual operation pouring mode. The concrete pouring device for cast-in-place ballastless track bed construction is characterized in that agenerator, a hopper and an electric push rod are arranged on the upper surface of a vehicle frame; three discharging bent pipes are arranged below the hopper, three discharging valve plates are arranged at discharging openings of the three discharging bent pipes respectively, a linkage rod is fixedly arranged on the three discharging valve plates in a penetrating mode, a connecting rod is fixedlyconnected to the linkage rod, and a push rod of the electric push rod is hinged to the connecting rod; and a first wireless receiving module is arranged beside a driving motor, and a second wireless receiving module is arranged beside the electric push rod. The purpose that an operator operates pouring operation outside the line is achieved, the damping effect is good, the construction precision and the construction efficiency are effectively improved, the construction cost is reduced, and the device is suitable for pouring operation of the cast-in-place ballast bed.

Description

technical field [0001] The invention relates to a pouring device for railway engineering construction, in particular to a concrete pouring device for cast-in-place ballastless track bed construction. Background technique [0002] Since the beginning of this century, my country has accelerated the pace of high-speed railway construction, and the use of CRTS I double-block and elastic-supported block ballastless tracks (referred to as cast-in-place ballastless track beds) has increased. At present, most of the domestic construction uses space positioning such as rail rows and formwork, and then uses conventional equipment such as gantry cranes, concrete tank trucks, and concrete pumps to perform concrete pouring operations. [0003] However, practice has shown that the existing conventional equipment plus manual pouring method has the following problems in application: First, it will affect the construction accuracy. Pouring, the shaking of the pouring device and the walking ...
