Concrete mixer truck for road and bridge construction

Abstract

The invention discloses a concrete mixing truck for highway bridge construction. The concrete mixing truck comprises a base truck body which is composed of a truck head and a rear frame, wherein a rectangular groove is formed in the upper end of the rear frame; a stirring drum support frame is arranged in the rectangular groove; a first driving device, a position fixing device, a stirring drum, astirring device and an auxiliary fixing frame are arranged at the upper end of the stirring drum support frame; the first driving device is composed of a driving gear, a driving motor and a toothed slot; a fastening device is arranged at the upper end of the auxiliary fixing frame; the fastening device is composed of an arc-shaped fastening ring, an arc-shaped through slot, a fastening block, a threaded through hole, a fastening bolt and a fastening nut; a drum sleeve is arranged at an opening end of the stirring drum along the peripheral direction of the outer wall; the position fixing deviceis composed of a threaded rod, a support rod, a semicircular arc fixing base, a groove, a support wheel and a torque-adjusting nut; the stirring device is composed of a speed reducer, a fixed bearing, a rotating shaft and a stirring mechanism. The concrete mixing truck has the beneficial effects of simple structure and high practicability.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a concrete mixer truck used for road and bridge construction. Background technique [0002] Concrete mixer truck is a special heavy-duty vehicle used for concrete transportation during highway and bridge construction. In the related art, the concrete mixer truck is composed of a headstock, a rear frame, a reducer and a mixing drum, etc., but the existing concrete mixer There are still some problems in the design and transportation of the transport vehicle. For example, the mixing drum is set on the upper end of the rear frame. The front and rear fixing brackets are movable and fixed, but in long-term use, the fixing brackets are likely to be slightly deformed due to the excessive load in the mixing drum; the concrete mixer truck rotates the mixing drum at the upper end to ensure the quality of the concrete it transports, but its The driving device is single, and the quality ...

[0002] Concrete mixer truck is a special heavy-duty vehicle used for concrete transportation during highway and bridge construction. In the related art, the concrete mixer truck is composed of a headstock, a rear frame, a reducer and a mixing drum, etc., but the existing concrete mixer There are still some problems in the design and transportation of the transport vehicle. For example, the mixing drum is set on the upper end of the rear frame. The front and rear fixing brackets are movable and fixed, but in long-term use, the fixing brackets are likely to be slightly deformed due to the excessive load in the mixing drum; the concrete mixer truck rotates the mixing drum at the upper end to ensure the quality of the concrete it transports, but its The driving device is single, and the quality assurance effect is not good. Therefore, a concrete mixer truck for road and bridge construction is needed. The device can also reduce the force of the fixed frames at both ends and increase its service life. It is also equipped with a first driving device and a stirring device to ensure the quality of the concrete in the mixing drum. It is also equipped with a tool box and a workbench for convenience. worker homework
