When straightening the member bar (the member bar of equipment scaffold frame is the hollow tube), the pressure of the axis of directional member bar is applyed from outside to inside to outside extrusion device, inside external stay device is from inside to outside applys the pressure of the axis direction of keeping away from the member bar, thereby it is great to have prevented that the portion of bursting contract (deforming to inwards cave in) area, can not carry out the external stay restoration with all the portion of bursting contract when the pipe fitting is thinner, the degree of bursting contract that has increaseed the portion of bursting contract or arouse the burst of other positions that take place even when having avoided one taste to increase inside pressure, thereby guarantee the repairing effect of member bar.
At the length position of the rod piece, a group of straightening rollers and a group of outer support rollers are correspondingly arranged, under the normal condition, the side of the crumple position of the rod piece can be deformed along with the outward protrusion, the outward protrusion deformation part is extruded by the straightening rollers from outside to inside, and the crumple position is extruded by the outer support rollers from inside to outside, so that the further crumple of the crumple position can be avoided, namely, the rod piece repairing effect is improved.
The newspaper straightening included angle between the group of straightening rollers and the group of outer supporting rollers is staggered at the same cross section position (namely, the same length position) of the rod piece due to the included angle so as to keep the same with the crumple part and the outward deformation formed by dislocation, and the newspaper straightening included angle is further beneficial to the fact that the straightening rollers can correspond to the outward deformation part and the outer supporting rollers can correspond to the crumple part, so that the repairing effect of the rod piece is further improved.
All the straightening rollers are driven by the first power, namely all the straightening rollers can provide friction force for the rod piece, and even if one of the straightening rollers in one group is idle after corresponding to the crumple part, the other straightening roller in the other group is driven by the first power, the other straightening roller still rotates, so that the rod piece is guaranteed to be conveyed smoothly, and continuous straightening repair is completed.
In addition, the connecting line of the centers of the straightening rollers in each group is a straightening roller distribution line, and the included angle between any two adjacent groups of straightening roller distribution lines is 90 degrees. Under the arrangement, when the straightening roller corresponds to the crumple part and the outer support roller corresponds to the outward bulging deformation part, the straightening roller is suspended without inward extrusion, the crumple part cannot be extruded inwards to increase the inward bulging degree of the crumple part, and the outer support roller is suspended without outward extrusion, the outward bulging deformation part cannot be extruded outwards to increase the outward bulging degree of the outward bulging deformation part. The straightening repair is only carried out after the straightening roller corresponds to the convex deformation part and the outer support roller corresponds to the defect part, so that the straightening effect is further improved.
With continued reference to fig. 1, fig. 2 and fig. 3, a specific structure of the first power mechanism is that it includes a driving motor 211, a speed reducer 212, a driving gear 213, a driving gear set 215 and an intermediate gear 215, which are sequentially connected in a transmission manner, wherein:

the driving gear set further comprises a subsequent driving gear set 2142, the subsequent driving gear set comprises a first subsequent driving gear 21421 and a second subsequent driving gear 21422, two subsequent straightening rollers of the subsequent set of straightening rollers are respectively fixed with one first subsequent driving gear and one second subsequent driving gear in a same-walking manner, the first subsequent driving gear is meshed with the second subsequent driving gear, and the first subsequent driving gear is meshed with the intermediate gear.
Through this kind of arrangement of first drive structure, can make driving motor drive the leveling roller of top, the leveling roller of below rotate according to opposite direction simultaneously to, make the member can advance along the straightening passageway, in order to accomplish the straightening repair operation.
In addition, the distance between the two straightening rollers of each set of straightening rollers is adjustably set. The pressure of the upper straightening roll and the lower straightening roll on the rod piece can be adjusted by adjusting the distance between the upper straightening roll and the lower straightening roll, so that the repair degree is selected, and if the distance is slightly smaller than the length (or radius) of the rod piece in the direction (the connecting line direction between the two straightening rolls), the repair effect is general, and a larger crumpled part and convex deformation are allowed to pass through a straightening channel; if the distance is reduced, the repairing effect is improved, the larger crumpled part and the convex deformation can be repaired, but the power requirement on the driving motor, the strength requirement on a transmission system and the wear-resisting requirement on the outer surface of the straightening roll are increased.
It should be further noted that one of the ways of adjusting the distance between the straightening rollers of the same group is, with continuing reference to fig. 3, that the external pressing device further comprises a first mounting plate 241, a second mounting plate 242, a first rotating shaft 251 and a second rotating shaft 252, wherein:

When the rod is a rectangular hollow tube, as shown in fig. 2, 4 and 5, the straightening channel is rectangular, and the outer support roller is cylindrical.

the working surface is positioned in the middle of the straightening roll in the length direction, and the two ends of the working surface form the transition surfaces respectively;
the radius of the working surface is smaller than the radius of the transition surface, i.e. the working surface bulges outwardly to a greater extent than the transition surface, and only the working surface is active when repairing a crumpled portion.
