Description

Technical Field

The invention belongs to the technical direction of electric power tower welding, and specifically relates to a welding device for a suspended electric power tower welding piece.

Background technique

Power towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers belong to space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The materials generally used are Q235 (A3F) and Q345 (16Mn). The rods are connected by rough bolts, which are connected by shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as tower feet are welded from several steel plates into an assembly. Therefore, hot-dip galvanizing for corrosion protection, transportation and construction are extremely convenient. For towers with a height of less than 60m, foot nails are set on one of the main materials of the tower to facilitate construction workers to climb the tower. Power towers are tower structures used to support and overhead wires, lightning conductors and other accessories, so that the wires and wires, wires and towers, wires and lightning conductors, and wires maintain a specified safety distance from the ground or cross-over objects.

In the process of welding power towers, existing devices often use manual welding, which requires multiple workers to perform welding operations, takes a long time, and directly places the power tower welded parts on the ground for welding, which will cause wear on the surface of the welded parts during movement, affecting future rust prevention.

Welding parts clamping operation:

When the construction personnel need to perform welding operations on the welding parts of the power tower, the construction personnel first use a towing vehicle to fix the first towing rod 11 on the welding device base 1, and then tow the welding device base 1 to the construction workshop and use tools to unscrew the four sets of lifting and fixing seats 14 to fix them on the ground. At this time, the construction personnel connect the external power supply to the welding device base 1, the welding device base 1 is started, the equipment program is started, and the construction personnel control the two sets of clamping manipulators through the equipment program to clamp the welded parts. The equipment program first detects the positions of the two ends of the welded parts through the first camera 23 and the second camera 231 and controls the two sets of clamping manipulators to clamp the two ends of the welded parts, and then places the welded parts on the welded parts placement plate 33. During the clamping process, the equipment program detects the force feedback value through the two sets of pressure sensors and compares it with the set value. The equipment program sets the clamping force of the two sets of clamping manipulators to X1, X2, and X3, X1 is the minimum value, X3 is the maximum value, and the force feedback value of the two sets of pressure sensors is Y1, which can be adjusted according to specific production needs. When the equipment program When the program controls two groups of clamping manipulators to use the clamping force of X1 to clamp the welded part, the equipment program detects whether the force feedback value is Y1. If it is Y1, the equipment program determines that the welded part is a thin welded part and no operation is performed. At this time, the clamping force is the minimum, and the force feedback value will not be greater than Y1. If it is less than Y1, the equipment program controls the clamping force of the two groups of clamping manipulators to increase to X2. When the equipment program controls the two groups of clamping manipulators to use the clamping force of X2 to clamp the welded part, the equipment program detects whether the force feedback value is Y1. If If it is Y1, the equipment program determines that the weldment is a medium-thick weldment and no operation is performed. If it is <Y1, the equipment program controls the clamping force of the two groups of clamping manipulators to increase to X3. When the equipment program controls the two groups of clamping manipulators to use the clamping force of X3 to clamp the weldment, the equipment program detects whether the force feedback value is Y1. If it is Y1, the equipment program determines that the weldment is a thick weldment and no operation is performed. At this time, it is the maximum clamping force, and the force feedback value <Y1 will not occur. After the clamping is completed, the equipment program controls the next operation;

By using two sets of clamping robots in conjunction with the equipment program, construction workers do not need to perform lifting, which reduces their loading burden. The clamping force can be changed according to different force feedback values to prevent excessive clamping force from causing surface wear of the welded parts, affecting the aesthetics, and to prevent excessive clamping force from causing loose welds and producing cold welds. The thickness of the welded parts can be detected while clamping to facilitate subsequent welding.

Preheating operation:

After completing the above operations, the equipment program controls the preheating operation. The equipment program controls the air compressor 37 and the hot air blower 43 to start. The equipment program sets the pumping value of the air compressor 37 to M1, M2, and M3, where M1 is the minimum value, M2 is the initial value, and M3 is the maximum value. The blowing time of the hot air blower 43 is T3, T2, and T1, where T3 is the maximum value and T1 is the minimum value. It can be modified according to specific production requirements. When the equipment program detects that it is a thick weldment, the equipment program controls the pumping value of the air compressor 37 to M1, the hydraulic lifting rod 32 retracts downward and drives the weldment to move downward to make it close to the two sets of hot air nozzles, and then the equipment program controls the hot air blower 43 to start, and the blowing time is T3. When T3 time is up, the equipment program detects the temperature of the weldment through the temperature sensor 34 and compares it with the set value. The equipment program sets the preheating temperature value to H1 (which can be modified according to production requirements). If the preheating temperature reaches H1, no operation is performed.

When the equipment program detects that the weldment is of medium thickness, the equipment program controls the pumping value of the air compressor 37 to be M1, the hydraulic lifting rod 32 retracts downward and drives the weldment to move downward to make it close to the two sets of hot air nozzles, and then the equipment program controls the hot air blower 43 to start, and the blowing time is T2. When the T2 time is up, the equipment program detects the temperature of the weldment through the temperature sensor 34 and compares it with the set value. The equipment program sets the preheating temperature value to H1 (which can be modified according to production requirements). If the preheating temperature reaches H1, no operation is performed;

When the equipment program detects that it is a thin weldment, the equipment program controls the pumping value of the air compressor 37 to be M1, the hydraulic lifting rod 32 retracts downward and drives the weldment to move downward to make it close to the two sets of hot air nozzles, and then the equipment program controls the hot air blower 43 to start, and the blowing time is T1. When the T1 time is up, the equipment program detects the temperature of the weldment through the temperature sensor 34 and compares it with the set value. The equipment program sets the preheating temperature value to H1 (which can be modified according to production requirements). If the preheating temperature reaches H1, no operation is performed;

If during the preheating process, the equipment program detects that the preheating temperature is less than H1, the equipment program determines that the outside weather is cold, and the equipment program controls the hot air blower 43 to continue to operate, and the two sets of hot air nozzles continue to blow hot air to the welded parts until the preheating temperature reaches H1;

By using the hydraulic lifting rod 32, the temperature sensor 34 and the equipment program in coordination, the weldment is brought close to the two sets of hot air nozzles during preheating, thereby improving the preheating efficiency and reducing the time required for preheating. At the same time, it can also reduce heat dissipation and reduce the energy consumption required for preheating, thereby achieving the effect of energy conservation and emission reduction. In cold weather, the temperature of the weldment is detected by the temperature sensor 34, and the preheating time is increased to ensure that the weldment can be fully preheated, thereby preventing the accuracy of the weldment from being affected and reducing the rework cost of the factory.

Welding Operation:

After completing the above operations, the equipment program controls the welding operation. When the equipment program detects that it is a thin welded part, the equipment program controls the pumping value of the air compressor 37 to be M3, the hydraulic lifting rod 32 rises upward and drives the welded part to move upward to make it close to the three groups of welding manipulators 51. At this time, the equipment program detects the welding position through the third camera 521 and controls the three groups of welding manipulators 51 to perform the welding operation. When the equipment program detects that it is a medium or thick welded part, the equipment program controls the pumping value of the air compressor 37 to be M2, the hydraulic lifting rod 32 rises upward and drives the welded part to move upward to make it close to the three groups of welding manipulators 51. At this time, the equipment program detects the welding position through the third camera 521 and controls the three groups of welding manipulators 51 to perform the welding operation;

By using the hydraulic lifting rod 32 in conjunction with the three sets of welding manipulators 51, the extension value of the hydraulic lifting rod 32 can be changed according to the thickness of the welded parts, so that the welded parts are brought close to the three sets of welding manipulators 51, thereby improving welding efficiency and preventing the occurrence of cold welding due to the long distance. At the same time, the moving distance of the three sets of welding manipulators 51 can be reduced, thereby reducing energy consumption.
