Description

Building scaffold steel pipe drawing-in machine

Technical field

The utility model relates to a kind of improvement of steel tube straightening machine, specifically a kind of building scaffold steel pipe drawing-in machine.

Background technology

Scaffolding steel pipe for building because length is longer, is using, is dismantling, transports, depositing in the process, produce bending because of collision or bearing capacity easily, this bending often also is big bending curvature, and the bending that also can produce the multistage different directions sometimes, as not alignment, then influence re-uses.At present, for the universal method of this steel pipe alignment be: with the manual method of beaing of sledgehammer, its weak point is: efficiency is low, waste time and energy, and is difficult to beat exactly straight.Because this steel pipe large usage quantity, uniform specification is so can adopt alignment equipment.At present, a kind of straightener is arranged, adopts the method alignment of rolling compaction, but complex structure, use inconvenient, production cost is high, so be difficult to apply.

Summary of the invention

The building scaffold steel pipe drawing-in machine that the purpose of this utility model is to provide a kind of operation simple in structure, easy, alignment accuracy height, can increases work efficiency, reduce labor intensity.

For reaching above purpose, the technical scheme that the utility model adopted is: this building scaffold steel pipe drawing-in machine, by the fixing operation platform, the rolling motor, the tractive motor constitutes, it is characterized in that establishing cylinder in the left part of fixing operation platform, cylinder by bearing fixing on the fixing operation platform, in cylinder, be set as the elasticity hammer that ring is arranged, fixing annular gear wheel on the outer wall of cylinder, annular gear wheel is meshed with the driving gear of rolling motor, on the driving shaft of tractive motor, establish the steel wire rope winding roller, one end of tractive steel wire rope is entangled on the steel wire rope winding roller, the other end is established steel pipe tensioner dop, is fixing opposite alignment finishing pipe on the fixing operation platform of cylinder rear end.The utility model is also implemented by following measure: described elasticity hammer can be established the 1-3 ring, distance between every ring is 50cm, every ring is established three, the inner face of three elasticity hammers contacts and is fastened as the circular hole more bigger than steel pipe overall diameter, the elasticity hammer is made of tup, spring, seat board, set bolt, the outer end of spring is welded on the seat board, the inner of spring is welded on the outer wall of tup, stretch out the circular hole of screw rod on the seat board from cylinder wall, be fixed on the wall of cylinder three equidistant settings of elasticity hammer in every ring with set bolt; Be made as horn mouth at the drum outlet end, bell-mouthed outlet diameter is than the big 1cm of diameter of steel pipe, and the steel pipe that opposite alignment finishing pipe is aimed in bell-mouthed outlet draws in mouth, and the diameter of cylinder is 40cm; Described steel pipe tensioner dop is made of taper pulling wedge, tensioner cover, and taper pulling wedge passes the tensioner cover, drag hook is established in the outer end of taper pulling wedge, and the tractive steel wire rope hangs over hook and goes up connection, as setscrew, from the outside tensioner of steel duct, block the mouth of pipe of steel pipe; Described opposite alignment finishing pipe is a straight tube, internal diameter is than the big 1cm of steel pipe, divide two semicircle pipe make-ups to form, one of them semicircle pipe is fixed on the fixing operation platform by support, another semicircle pipe is fixed on the sliding seat, establish rotation in the outside of sliding seat and turn handle, the outer end that handle is turned in rotation connects catch bar, by the push-and-pull of catch bar, rotates and turns the handle rotation, realize moving of sliding seat, thereby realize the folding of two semicircle pipes, handle is turned in rotation can establish 3-5, all is connected with same catch bar, rotation is turned the middle part circle hole sleeve of handle on fixed axis, and fixed axis is fixed on the fixing operation platform.When using the utility model, it is fixing with the mouth end that passes the steel pipe in the cylinder that steel pipe tensioner dop is passed opposite alignment finishing pipe, start the tractive motor, steel pipe can be drawn in the opposite alignment finishing pipe, restart the rolling motor, make rollers roll, because behind the tube bending, the axis of steel pipe can depart from the axis direction of opposite alignment finishing pipe, so, when cylinder rotates, its inner elasticity hammer then constantly hits the knee, through the strike that the elasticity of 1-3 ring is hammered into shape, the steel pipe that becomes more straight is just continued to be drawn in opposite alignment finishing pipe, in the process that draws in opposite alignment finishing pipe, be subjected to the squeezing action of opposite alignment finishing pipe, make the further alignment of steel pipe, after drawing in opposite alignment finishing pipe fully, illustrate that then steel pipe is by complete alignment, promote catch bar, make to rotate and turn the handle counter-rotating, can open opposite alignment finishing pipe, take out by the steel pipe of alignment.

The beneficial effects of the utility model are: compare with the steel tube straightening machine of present use, simple in structure, easy operation, time saving and energy saving, alignment precision height can be exclusively used in the alignment of scaffolding steel pipe for building.
