Description

Automatic winding and final assembly equipment for electric pole and tubular pile prestressed reinforcement cage

Technical Field

The invention belongs to the technical field of steel reinforcement cage winding equipment, and particularly relates to automatic winding and final assembly equipment for an electric pole and a tubular pile prestressed steel reinforcement cage.

Background

The prestressed reinforcement cage is a reinforcement mesh framework of a conical concrete electric pole and a cylindrical concrete pipe pile, and the reinforcement cage can be subjected to cold wire drawing and winding only after being tensioned to a certain tensioning tension. In the existing equipment, cold-drawn wire knotting detection and steel reinforcement cage tensioning are generally carried out manually, after the cold-drawn wire and the steel reinforcement cage are detected, the cold-drawn wire and the steel reinforcement cage are respectively conveyed to corresponding winding equipment, winding of the cold-drawn wire on the steel reinforcement cage is completed, manual feeding, conveying and the like are needed in the whole process, and the whole working efficiency is reduced.

Meanwhile, in the current steel reinforcement cage tensioning in the industry, an electric hoist is used for tensioning, one end of the steel reinforcement cage is fixed on a steel frame upright post, the other end of the steel reinforcement cage is connected with an electric hoist hook, the electric hoist is operated manually, the steel reinforcement cage is tensioned to the tensioning force considered by an operator to be proper, and then cold-drawn wire winding is carried out. Tension force detection is not carried out in the whole tensioning process, the tension force detection is completely judged by the experience of workers, and the tension force is large or small in production, so that the cold-drawn wire of the steel reinforcement cage is loosely and unevenly wound, and the quality cannot be guaranteed; and when the tension pressure of the electric hoist is overlarge, potential safety hazards exist.

It can know, current to steel reinforcement cage tensioning process, no tension value detects, relies on artifical the judgement completely, and the stretch-draw pulling force deviation that leads to every steel reinforcement cage of same specification is great easily, influences product quality. After the reinforcement cage is tensioned, the tensioning force can rise rapidly due to slight tensioning extension, and the tensioning force is difficult to judge manually. The tensioning force is too large, so that the risk of damaging the steel reinforcement cage and equipment and the potential safety hazard of personnel can exist.

At present, in the process of winding a cold-drawn wire in a reinforcement cage in the industry, the traditional manual detection of the knotting condition of the cold-drawn wire is firstly carried out; and carry out the detection of the cold-drawn wire condition of knoing by the manual work, not only detection efficiency is low like this, and the cost of labor is high, and the whole bundle of cold-drawn wire is circular moreover and bulldozes inconvenient detection.
