Motorized construction machine

Abstract

The invention discloses a motorized construction machine. The motorized construction machine structurally comprises a machine body, a button, a workbench, a telescopic table and an arc bending roller,wherein the button is installed on the front face of the machine body, the workbench is fixed to the top of the machine body, the arc bending roller is movably clamped to the top of the workbench, the telescopic table is in bolted connection with the top of the workbench and movably matched with the arc bending roller, a reinforcing steel bar arc bending machine is used for carrying out arc bending on a reinforcing steel bar, the reinforcing steel bar is limited by a buffer block during arc bending, so that the problems that the position of the sharp-corner-shaped notch is changed during arcbending, the sharp-corner-shaped notch extrudes the roller surface, the roller surface is damaged, when the damaged part of the roller surface is in contact with the reinforcing steel bar, a purification film on the surface is easily scraped to cause rusting of the scraped part, the rusting speed of the reinforcing steel bar is increased, and use is influenced are solved; and a brush block of a rotating rod is used for brushing away and collecting cuttings of the notch, and the situation that the notch of the steel bar contains filamentous cuttings, the cuttings fall off and are accumulated onthe surfaces of the limiting plates during arc bending, the reset block between the limiting plates is clamped, and limiting and buffering are affected during steel bar arc bending is avoided.

Description

technical field [0001] The invention belongs to the field of construction machinery, and more specifically, relates to a mobile construction machinery. Background technique [0002] During building construction, in order to strengthen the firmness and bearing capacity of the building, steel bars are installed on the construction site, and then concrete is poured to wrap the steel bars inside. Due to different buildings, some of the steel bars used are in the shape of arcs. The rollers of the arc machine are constantly rolling to bend the segmented steel bar into an arc shape; when the steel bar bending machine is used in the prior art, because the cut of the steel bar after the segment is sharp-edged, when the sharp-edged cut is bent Extruding with the surface of the roller will cause damage to the surface of the roller and make the surface uneven. There is a layer of purification film on the surface of the steel bar. When the damaged part of the roller surface is in contact...

[0002] During building construction, in order to strengthen the firmness and bearing capacity of the building, steel bars are installed on the construction site, and then concrete is poured to wrap the steel bars inside. Due to different buildings, some of the steel bars used are in the shape of arcs. The rollers of the arc machine are constantly rolling to bend the segmented steel bar into an arc shape; when the steel bar bending machine is used in the prior art, because the cut of the steel bar after the segment is sharp-edged, when the sharp-edged cut is bent Extruding with the surface of the roller will cause damage to the surface of the roller and make the surface uneven. There is a layer of purification film on the surface of the steel bar. When the damaged part of the roller surface is in contact with the steel bar, the purification film on the surface is easily scraped off, resulting in being scraped off Parts are rusted, which will speed up the rusting speed of steel bars and affect the use
