Telescopic arm of leveling machine

Abstract

The invention discloses a telescopic arm of a leveling machine, and relates to the field of leveling machines. The telescopic arm comprises a first-section arm, a second-section arm and a third-section arm, the telescopic arm further comprises a telescopic mechanism, the second-section arm is movably installed on the first-section arm, the third-section arm is movably installed on the second-section arm, the telescopic mechanism comprises a connecting element used for connecting the first-section arm, the second-section arm and the third-section arm and a driving element used for driving the second-section arm and the third-section arm to move, and the driving element is used for driving the second-section arm to move and driving the third-section arm and the second-section arm to stretch out and draw back at the same time through the connecting element, so that the construction distance is adjusted, and the construction efficiency is improved. In the construction process, the working stroke of a working head can be further increased and extended through step-by-step extension of the three-section arm, so that the construction efficiency is further improved, meanwhile, a guide rail is machined and designed through square steel, reamed hole bolts are fixed to the telescopic arm, the straightness and planeness of the guide rail can be guaranteed, and the guide rail is simple, efficient and easy to machine.

Description

technical field [0001] The invention relates to the field of screeds, in particular to a telescopic arm of a screed. Background technique [0002] The leveling machine is a floor construction equipment that uses high-frequency vibration of the motor to discharge the air in the concrete and ensure the flatness of the surface layer. The telescopic arm is the main working part of the leveling machine. The working head of the leveling machine is installed on the telescopic arm. On one end, the telescopic arm is used to drive the working head of the leveling machine to perform concrete leveling construction operations. [0003] At this stage, all the fixing methods of the guide rails of the telescopic arm are welded. Due to the long guide rails, it is easy to cause welding deformation during the welding process. high.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a telescopic arm of a leveling machine to solve the problem that the existing telescopic arm guide rails are all fixed by welding. Since the guide rail is long, it is easy to cause welding deformation during the welding process. After the welding is completed, in order to ensure straightness and flatness, it is necessary to perform post-welding processing again, which is difficult to process and high in processing cost.
