Abstract

The invention discloses a tunnel inverted arch rebar connecting rib bending machine which comprises a supporting face plate, a rolling shaft, a driving mechanism and an ejector. A first guide wheel is arranged at one end of the supporting face plate, a second guide wheel is arranged at the other end of the supporting face plate, an adjusting hole is formed in the supporting face plate, the adjusting hole is formed between the first guide wheel and the second guide wheel and is formed in one side of the connecting line of the first guide wheel and the second guide wheel, a bearing is arranged on the rolling shaft and arranged in the adjusting hole, a rolling wheel is arranged at one end of the rolling shaft, the other end of the rolling shaft is connected with the driving mechanism, the first guide wheel, the second guide wheel and the rolling wheel are all arranged on the front side face of the supporting face plate, and a sliding groove allowing the driving mechanism to slide along with the rolling shaft is formed in the rear side face of the supporting face plate. The tunnel inverted arch rebar connecting rib bending machine can pre-bend one portion of an inverted arch rebar connecting rib, and can further carry out continuous rolling on the inverted arch rebar connecting rib, and the bending of the inverted arch rebar connecting rib is achieved.

Description

technical field [0001] The invention relates to a steel bar bending machine, in particular to a tunnel inverted arch steel bar stubble bar bending machine. Background technique [0002] During the construction of tunnel inverts, generally 1 to 2 meters of stubble bars are reserved for the invert reinforcements. Since this part of the steel bar is at the end of the inverted arch, it fails to form a natural arc with the inverted arch steel bar. Therefore, it is necessary to pre-bend the stubble reinforcement. [0003] At present, the pre-bending method for the stubble part of the inverted arch steel bar is: pre-bend the inverted arch steel bar on the desktop pre-bending machine in the steel bar processing plant, and need to use large lifting equipment to hoist the steel bar to the desktop pre-bending machine. At least two operators lift the inverted arch steel bars to the pre-bending machine for pre-bending. After the pre-bending is completed, it is hoisted and transported ...
