Automatic leveling plastering machine

Abstract

The invention discloses an automatic leveling plastering machine, comprising a track, a rack, a telescopic work arm, a swaying driving device, a swaying gearing device, a swaying brake, an automatic leveling plastering device, a walking driving device, a plastering datum plate, a delivery pump, a delivery soft pipe and a control system, wherein, the telescopic work arm is connected on the upper part of the rack through being fixed with a rotating shaft and can swing with the rotating shaft, and the swaying angle alpha thereof is more than 180 degrees; the automatic leveling plastering device is hinged at the end of the telescopic work arm and comprises a mounting plate, datum piston shoes, a head, an angle measuring sensor, a head displacement sensor, a plastering device angle-adjusting unit and a head displacement adjusting unit. The automatic leveling plastering machine has the functions of automatically and timely monitoring plastering planeness and adjusting levelling, and has the advantages of high operation precision, reliable performance and simple operation, thereby being widely applied to the plastering of the inside and outside walls of buildings and the brushing of decorative paints.

Description

technical field [0001] The invention relates to a wall plastering machine, which belongs to the technical field of construction machinery. Background technique [0002] In housing construction, the finishing project of walls and floors is an important project with a large amount of work, high cost and high quality requirements. For a long time, in the finishing engineering of building construction both at home and abroad, the mortar smoothing and paint painting on the inside and outside of the wall and the top surface of the floor are all completed by manual operation, and scaffolding is needed at high places. The resulting problems are: it takes up a lot of labor, the work efficiency is low, and the construction period is long, which seriously affects the progress of the project. [0003] Although the design results of wall plastering machines with different structures have been announced, so far there is no commercialized product of the plastering machine for sale. The re...

Problems solved by technology

The resulting problems are: it takes up a lot of labor, the work efficiency is low, and the construction period is long, which seriously affects the progress of the project.

[0003] Although the design results of wall plastering machines with different structures have been announced, so far there is no commercialized product of the plastering machine for sale. The reason is that the existing plastering machines themselves have technical defects: there is no automatic leveling during operation system, the plastering machine has poor structural rigidity, the construction process itself is prone to human errors, and the operation is cumbersome, etc., which eventually leads to the plastering quality not meeting the specified flatness and finish requirements, and the product is not practical and cannot be accepted by users

For example, the structural feature of the existing plastering machine is that the plastering head is installed on the column or door frame of the machine, and the column or door frame is fixed on the chassis. It can move up and down on the column or door frame, and the movement of the adjacent station is to manually push the whole machine to move a certain distance along the parallel line released in advance after the plastering of the previous station is completed (this distance The length is slightly smaller than the width of the first plastering), so as to reach the next station, which may easily cause deviations in the thickness of the plastering in adjacent stations; on the other hand, due to the insufficient rigidity of the plastering machine itself, uneven ground , the verticality deviation of each installation of the column or the door frame, and the reverse thrust of the plastering head make the whole machine shift along the plastering thickness direction to form a deviation, etc., which will cause the plastering quality to fail to meet the requirements
