Straightening and cutting device for steel bars in the construction of iron towers for outdoor transmission lines

Abstract

The invention discloses a rebar straightening and cutting device used for construction of an outdoor electric transmission line iron tower. The rebar straightening and cutting device comprises a back board. A guiding block and a fixing table are arranged on the side wall of the back board. The guiding block is provided with a first movable rod. The first movable rod is inserted into the guiding block and can move in the axial direction of the guiding block. A connecting plate is arranged at the bottom end of the first movable rod. A pressing rod is arranged on the connecting plate. A pressing plate is arranged on the pressing rod and can rotate around the pressing rod. The fixing table is located right below the connecting plate. A spring is arranged between the connecting plate and the fixing table. One end of the spring is connected with the connecting plate, and the other end of the spring is connected with the fixing table. A second movable rod is further arranged on the fixing table. One end of the connecting rod is connected with the connecting plate, and the other end of the connecting rod is provided with a tool bit. The rebar straightening and cutting device is simple in structure, convenient to operate and carry and capable of straightening bent rebars and cutting the rebars off when the rebars are straightened, and thus the working efficiency is improved.

Description

technical field [0001] The invention relates to a steel bar processing device, in particular to a straightening and cutting device for steel bars in the construction of iron towers for outdoor power transmission lines. Background technique [0002] Transmission line towers are generally divided into five types according to their shapes: wine glass type, cat head type, upper type, dry type and barrel type. Replacement wire phase position tower), terminal tower and spanning tower, etc. Their structural characteristics are that all kinds of tower types are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel, and the material is generally Q235 (A3F) And Q345 (16Mn), two kinds of rods are connected by rough bolts, which are connected by bolts under shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Some parts such as tower feet are welded into an assembly by several steel plate...

AI Technical Summary

Problems solved by technology

At present, artificial straightening or special straightening machines are generally used for straightening steel bars. The method of manual straightening needs to straighten both ends of the steel bars separately, and it is easy to scratch yourself during the straightening process. Although the machine has high efficiency and consumes less labor, it is generally large in size. When used outdoors, due to the limited space, it is not convenient to install the leveler in some places, and it is also not easy to carry. At the same time, some longer steel bar levelers After straightening, it needs to be cut, which undoubtedly adds another process to the operators and reduces work efficiency.
