Raw material stirring device for highway bridge duct grouting

Abstract

The invention discloses a raw material stirring device for highway bridge duct grouting, and belongs to the technical field of bridge construction. The raw material stirring device for the highway bridge duct grouting solves the problem that an existing device cannot crush a blocky raw material and affects the stirring effect. The device is technically characterized by comprising a base, a supportand a stirring box, wherein the stirring box is arranged on the base, the support is arranged outside the stirring box, a stirring assembly is arranged inside the stirring box, a smashing assembly used for smashing the raw material is installed on the stirring assembly, a motor installation base is fixedly installed at the top of the support, and a servo motor is fixedly installed on the motor installation base. According to the embodiment of the invention, the smashing assembly is arranged, the smashing treatment on the blocky raw material in the stirring box is realized, the protection on aswinging rod and a striking block is realized through arrangement of an outer protection ring, and meanwhile, the striking block can be limited, so that the striking block is prevented from strikingthe side wall of the stirring box in a swinging process, and the service life of the stirring box is prolonged.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a raw material stirring device used for grouting of tunnels of highway bridges. Background technique [0002] In building construction, the prestressed corrugated pipe is pre-embedded in the concrete prestressed component. After the concrete is poured and the concrete reaches a certain strength, the prestressed corrugated pipe is threaded into the prestressed tendon, and the prestressed tendon is stretched. After anchoring, the prestressed corrugated pipe channel is grouted, so that the grout fills the gap between the prestressed tendon and the channel, so that the prestressed tendon and the concrete are firmly bonded together, and the strength, stiffness and bending resistance of the concrete component are improved. [0003] Chinese patent CN205055890U discloses a high-speed mixing device for pressing slurry, which includes a hand electric drill, an agitator and a mi...
