Description

Technical Field

[0001] The utility model relates to the technical field of carbon steel repair devices, and more specifically, to a nuclear power carbon steel hairline repair and treatment device. Background Art

[0002] Carbon steel hairline repair is a process for restoring and repairing the surface texture of carbon steel. Carbon steel often shows hairline cracks, wear or scratches due to long-term use or external factors, affecting its appearance and function. Currently, an electric spark surfacing repair machine is usually used to fill and repair cracks or holes on the surface of carbon steel, and the surface of the carbon steel part is polished and leveled by grinding. However, there are still problems in this repair process. For example, during the above cold welding repair process, the operator needs to hold the electric spark surfacing repair machine and the welding wire at the same time and accurately apply the welding wire to the welding head. However, performing such an operation for a long time will cause the operator's arm to fatigue, resulting in a decrease in the holding stability, affecting the welding accuracy, and thus reducing the actual repair effect.

[0025] Among them, a fixture 3 is further included, and the bottom of the fixture 3 is fixedly installed with the top of the fixing base 1.

[0026] Among them, the movable frame 2 includes a first support 20, a guide rod 21, and a second support 22. The bottom end of the first support 20 is slidably installed on the inner surface of one side in the width direction of the fixing base 1. One end of the guide rod 21 is fixedly installed with the top of the first support 20, and the other end is fixedly installed with the top of the second support 22. The second support 22 is slidably installed on the inner surface of the other side in the width direction of the fixing base 1.

[0027] Among them, the movable frame 2 further includes an electric telescopic rod 23 and rollers 24. The electric telescopic rod 23 is arranged inside the fixing base 1 close to the first support 20. One end of the electric telescopic rod 23 is fixedly installed with the inner surface of the fixing base 1, and the other end is fixedly installed with the surface of the bottom end of the first support 20. The rollers 24 are respectively arranged at the bottoms of the first support 20 and the second support 22;

[0028] By providing the rollers 24, and the rollers 24 are arranged at the bottoms of the first support 20 and the second support 22, the sliding friction between the bottom surfaces of the first support 20 and the second support 22 and the fixing base 1 can be converted into rolling friction, so that the movement of the first support 20 and the second support 22 is more labor-saving, reducing energy loss and wear of mechanical components.

[0029] Among them, the cold welding repair assembly 4 further includes a motor 42, a threaded rod 43, and a collar 44. The motor 42 is arranged in the middle of the top of the frame 41. The output end of the frame 41 is fixedly installed with the top of the threaded rod 43. The top end of the threaded rod 43 is rotatably installed on the inner surface of the top of the frame 41, and the bottom end of the threaded rod 43 is rotatably installed in the middle of the bottom of the frame 41. Both ends of the collar 44 are fixedly installed with the tops of the two L-shaped connecting plates 45, and the middle of the collar 44 is threadedly connected to the outer surface of the threaded rod 43.

[0030] Among them, the cold welding mechanism 46 includes a feeder 460, a connecting plate 461, a welding wire 463, and a surfacing repair machine 464. The top of the feeder 460 is fixedly installed with the bottom of the L-shaped connecting plate 45. There are two connecting plates 461. One end of the two connecting plates 461 is fixedly installed on the side surface of the feeder 460, and a pressing wheel 462 is rotatably installed in the middle of the other end.

[0031] By setting the feeder 460 and the pressing wheel 462, a mechanism for the horizontal feeding of the welding wire 463 is provided inside the feeder 460. Through the opposite rotation of the symmetrically arranged rubber conveyor belts, the pushing effect on the welding wire 463 therebetween is achieved. And the pressing wheel 462 arranged on the outer surface of the feeder 460 through the connecting plate 461 can produce a certain twisting effect on the welding wire 463, so that the welding wire 463 is in a suitable welding contact point.

[0032] The working process of the present utility model is as follows:

[0033] First, the carbon steel to be repaired is clamped and fixed by two groups of clamps 3 symmetrically arranged on the top of the fixed seat 1. Then, control the electric telescopic rod 23 to extend or contract, and push the connected first support column 20 to slide horizontally along the inner surface of the fixed seat 1, driving the guide rod 21 connected to the top and the second support column 22 on the other side to move together, so that the cold welding repair assembly 4 installed on the surface of the guide rod 21 also moves horizontally, thereby quickly adjusting the position of the cold welding mechanism 46 in the X-axis direction. In addition, the electric slider 40 can be controlled to start, so that the electric slider 40 moves along the surface of the guide rod 21, thereby quickly adjusting the position of the cold welding mechanism 46 in the Y-axis direction, making it reach the end position of the scratch or notch that needs to be repaired on the carbon steel. And at the same time of starting the cold welding repair, by controlling the movable frame 2 and the electric slider 40, the cold welding mechanism 46 is moved along the scratch or notch of the carbon steel, achieving quick adjustment of the welding position during the repair and improving the efficiency of cold welding repair;

[0034] After adjusting the X and Y axis positions of the cold welding mechanism 46 to the positions where the carbon steel needs to be repaired, the staff can control the motor 42 to start. The threaded rod 43 connected to the output end of the motor 42 rotates, driving the collar 44 connected by external threads to slide up or down along the side of the frame 41, driving the L-shaped connecting plates 45 connected to both ends of the collar 44 to move, so as to adjust the position of the cold welding mechanism 46 in the Z-axis direction, making the welding wire 463 inserted into the feeder 460 reach the required repair position. And the surfacing repair machine 464 will be in contact with the end of the welding wire 463. At this time, starting the surfacing repair machine 464 can carry out surfacing welding on the scratches or defects of the carbon steel. Through the above structure, it is not necessary for the operator to directly hold the welding wire 463 and the surfacing repair machine 464, achieving the effects of saving effort, improving stability, and improving the actual cold welding repair effect.
