Device for regulating sectional dimension of stirrup box of steel reinforcement framework machine

Abstract

The invention discloses a device for regulating a sectional dimension of a stirrup box of a steel reinforcement framework machine. The device comprises a spiral mechanism which is arranged along the cross section of the stirrup box, and a chain transmission mechanism used for driving the spiral mechanism; each amplitude regulating lead screw, two ends of which are fixedly arranged on the bottom frame of the stirrup box, in the spiral mechanism and a nut connected with a movable frame of the stirrup box define a spiral pair; and the chain transmission mechanism is mounted on the bottom frame ofthe stirrup box to drive the amplitude regulating lead screws to rotate, so that the movable frame of the stirrup box moves along the nut. Two groups of the amplitude regulating lead screws, which are symmetrically arranged in parallel, of the spiral mechanism are the same in thread direction, and are separately connected with a chain wheel of the chain transmission mechanism. Joints of the nutsof the spiral mechanism and the movable framework of the stirrup can be equipped with slide rails, and two nuts are arranged on the same amplitude regulating lead screw in a spaced mode, so that the movable frame of the stirrup box is supported and is guided to move. The device can be used to regulate breadth, namely sectional dimension, of the stirrup box according to the dimensions of the spiralcontinuous stirrups, and therefore, the stirrups are conveniently stored.

[0002] The forming of the steel bar skeleton adopts a special seam welding machine to weld multiple round or square main bars and spiral stirrups wound on the main bar. When the steel bar frame is formed, a driving system is required to drive the main bar and the formed frame relative to the traction system. Rotate to realize the winding of stirrups on the main reinforcement. This forming method improves the mechanization level of steel skeleton forming to a certain extent, but there is still a gap with the energy-saving and environmentally friendly production process advocated by the country, and for different specifications of polygonal cross-section steel The skeleton is also difficult to shape with this method

In addition, the manufacturing process of the spiral stirrup on the steel frame directly affects the quality and production efficiency of the steel frame. When the existing steel frame seam welding machine makes the steel frame, it needs to be welded while winding the spiral stirrup. If the spiral stirrup is pre-processed Compression "spring shape" can save the forming time of the steel frame; the existing steel frame seam welding machine has a single style of steel frame, which can only surround the outer circumference of the main bar. If the spiral stirrup is pre-processed into a spiral shape, the stirrup The method of placing the main reinforcement first and then inserting it can produce a steel skeleton with a staggered network structure of spiral stirrups. This new reinforcement skeleton forming method requires special reinforcement skeleton forming equipment. The key part of this equipment is the spiral continuous stirrup pressure storage. And orderly release device - stirrup box
