Automatic welding and forming machine of reinforcing steel bar skeleton of telegraph pole

Abstract

The invention discloses a rotary positioning machine of a reinforcing steel bar skeleton of a telegraph pole, and the machine comprises a rotary part and an auxiliary rotary part. The invention also provides an automatic welding and forming machine of the reinforcing steel bar skeleton of the telegraph pole, and the machine comprises the rotary positioning machine of the reinforcing steel bar skeleton of the telegraph pole, main reinforcing steel bars and a frame stress circle which are rotated and positioned to form the reinforcing steel bar skeleton of the telegraph pole, and a spot welding machine, of the reinforcing steel bar skeleton of the telegraph pole, which is used for welding the main reinforcing steel bars and the frame stress circle so that the reinforcing steel bar skeleton of the telegraph pole is formed. The automatic welding and forming machine of the reinforcing steel bar skeleton of the telegraph pole has the main advantages that due to the resistance welding, all weldingspots are welded firmly, and the welding quality is stable; the verticality of the frame stress circle and the main reinforcing steel bar can be ensured; the production efficiency is high; the cost is low; the structure is simpler, the maintenance is convenient, and the maintenance cost is low; no pollution is produced to the environment, and harm to welders and other workers is prevented; reinforcing steel bar drawing welding can be carried out; the working environment is neat and fresh, and potential safety hazards are reduced; the main reinforcing bar spacing is accurate; and reinforcing steel bar skeletons of telegraph poles with different diameters, lengths, quantity of main reinforcing steel bars and different main reinforcing steel bar diameters can be welded.

Description

technical field [0001] The invention relates to the technical field of welding and forming production, in particular to welding and forming equipment for steel bar skeletons of electric poles. Background technique [0002] In the field of pole manufacturing, including the manufacture of reinforced concrete poles, it is still mainly manual operation. First, put nearly half of the main reinforcement on several tooth molds lined up in a row. The main reinforcement includes full-length reinforcement and full-length reinforcement, which are all pre-made, and then the supporting ring is placed at the end, with a certain distance in the middle—such as 500mm ——Place a tension ring, and then the welder uses carbon dioxide shielded welding or arc welding to weld the contact points of each steel bar and each tension ring together one by one. After completion, put the semi-finished product into another row of tooth molds where the steel bars are placed continue welding. Then the welde...

AI Technical Summary

Problems solved by technology

[0005] The second type of frame is processed by machine, so the labor intensity is relatively low, but due to the use of thicker cold drawing, and there are many solder joints, the cost is higher, and the frame with a small tip diameter cannot be processed, and butt welding cannot be used. There is the main rib of the welded joint at the end, because the diameter of the welded joint is larger than the main rib of the main rib, the welded joint cannot pass through the guide bar hole on the welding plate smoothly, if the guide bar hole is enlarged, the welding plate in the direction of the tip end cannot be arranged enough number of rib holes

[0007] 1. The process of the entire steel bar skeleton of the pole is manually operated. Whether the welding fastness of each solder joint is guaranteed, and whether the perpendicularity between the supporting ring and the steel bar is guaranteed depends entirely on the personal experience of the welder, and it cannot be consistently guaranteed every time. All pole steel skeletons are of excellent quality

If the solder joints are weak or the strength is not enough, it will form a weak point. When subjected to abnormal external forces-such as typhoons, vehicle collisions, abnormal pulls by cables, etc.-it is easy to cause poles due to this weak point. completely or even broken, causing unnecessary accidents and losses

Similarly, if the perpendicularity between the tension ring and the steel bars cannot be guaranteed, the cross-section of the steel bar skeleton of the electric pole at this place is an ellipse, and the spacing between the steel bars here will be reduced. The crushed stones will form cavities, which will seriously affect the strength of the pole and become waste products.

[0008] 2. The process of the entire pole steel frame is manually operated, and the production efficiency is low. Due to the different proficiency of the welders, the welding time is different

[0009] 3. Arc welding and carbon dioxide shielded welding will have arc light, metal dust, etc., which will pollute the environment. Although more exhaust fans, induced draft fans and other measures are taken in the factory building, the working environment is still relatively harsh, which is more or less harmful to welders and other workers. dangerous

At the production site, welding machines, welding wires, welding rods, and gas cylinders are stored on the spot, and power lines are also dragged on the ground, which makes the site messy and poses a safety hazard

[0010] 4. Arc welding and carbon dioxide shielded welding will consume consumables such as welding rods, welding wires and carbon dioxide. Each year, depending on the production situation, such consumables alone need to spend 100,000 to 300,000 yuan
