Automatic painting device for inner wall of round pit

Abstract

The invention relates to an automatic painting device for the inner wall of a round pit, and solves the problems that in the prior art, concrete is difficult to smear on the inner wall of the round pit, and the smearing efficiency is low. According to the technical scheme, the automatic painting device comprises a concrete smearing device, a storage barrel and a driving smearing mechanism, wherein the driving smearing mechanism comprises a vertical moving unit, a circular motion unit and a reciprocating rotation unit, the concrete smearing device is rotationally connected with the storage barrel, the circular motion unit drives the concrete smearing device to do circular motion, and after at least one circle of circular motion is performed at the same horizontal position, the vertical moving unit drives the concrete smearing device to move downwards; and when the concrete smearing device and the protruding end are located at the same horizontal position, the reciprocating rotating unit drives the concrete smearing device to rotate, and when the concrete smearing device makes contact with the protruding end, the reciprocating rotating unit drives the concrete smearing device to rotate reversely. The automatic painting device is novel in conception, ingenious in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of building construction machinery, in particular to an automatic painting device for the inner wall of a circular well. Background technique [0002] The size of the round shade well is generally between 600mm and 800mm in diameter, and the depth is generally more than 1.5 meters. The inner wall of the shade well usually needs to be smeared with concrete. Due to the size limitation of the shade well, that is, the diameter is small and the depth is deep. When making concrete, the operator usually lays on the edge of the well to smear, but when lying on the edge of the well, the side wall near the bottom of the well is not easy to touch and cannot be handled. When it is necessary to smear the lower side wall, sometimes Pour the mixed concrete raw materials into the shade well, and the operator enters the well to smear. During the process of smearing concrete, the operator needs to continuously take the concrete raw mat...
