Background technology
The tunnel excavation country rock is ever-changing; Become circulating application worker requirement in order in time to satisfy excavation back supporting fast; Prevent that the tunnel from caving in; Must catch Best Times to accomplish the supporting Cheng Huan of excavation back weak surrounding rock, the steel bow member is the important means of supporting Cheng Huan, is that current tunnel support rapid construction becomes one of ring urgent problem so accomplish the processing of steel bow member at the construction field (site).
Summary of the invention
The utility model can't provide the bending apparatus of the on-the-spot steel bow member processing of a kind of suitable constructing tunnel in the problem of constructing tunnel field machining in order to solve the steel bow member.
The utility model is to adopt following technical scheme to realize: be fit to the bending apparatus of the on-the-spot steel bow member processing of constructing tunnel, the startup cabinet that comprises job platform, two setting motors, oil cylinders, is supported in roller bearing on the job platform, links to each other with oil cylinder with two setting motors respectively through electric wire and hydraulic control circuit and several rolling bar groups that are arranged at the job platform both sides; Cycloidal planetary gear speed reducer and the symmetrical vertical fixing end in the job platform both sides all is installed on the output shaft of two setting motors, and oil cylinder is fixed in the other end of job platform and is positioned at the centre of two cycloidal planetary gear speed reducers; Oil cylinder is provided with graduated scale.During work, I-steel is got on the job platform through the rolling bar group that is arranged at job platform one side is artificial auxiliary, make the output shaft of I-steel and two cycloidal planetary gear speed reducers be in contact and be positioned on the roller bearing that is supported in job platform; Two setting motors of control device control turn round in the same way in the startup cabinet, and the output shaft of erectting motor drives the output shaft rotation of cycloidal planetary gear speed reducer, and I-steel rolls through the roller bearing that is supported on the job platform under the output shaft drive of cycloidal planetary gear speed reducer; Simultaneously vow distance according to the radius of the radian of the I-steel that calculates, observe oil cylinder high scale scale, the pushing tow axle that starts control device control oil cylinder in the cabinet withstands I-steel and travels forward and make I-steel reach needed radian; I-steel has so just obtained the steel bow member of moulding through being arranged at the rolling bar group output of job platform opposite side then.Said rolling bar group, the control device that starts in the cabinet are the technology that those skilled in the art realize easily.
Further, the both sides of said oil cylinder are provided with the pushing tow axle control steel plate that is supported on the job platform, and a side of pushing tow axle control steel plate has groove; Be with the housing that can in groove, be free to slide on the pushing tow axle of oil cylinder; Skew about the pushing tow that can prevent oil cylinder like this takes place during motion before axially.
The utility model is simple to operate, and laborsaving and easy grasp has realized constructing tunnel field machining steel bow member, has reduced the processing cost of steel bow member in factory, has deducted transit link; Having solved the steel bow member can't can process adaptable across the job site of all tunnel steel arch frames in the problem of constructing tunnel field machining.
