[0016] Compared with related technologies, the laser cladding repair equipment for turbine runner blades provided by this invention has the following beneficial effects: This invention provides a laser cladding repair device for turbine runner blades. The entire working structure is supported by a vehicle body. A retractable and movable mechanism allows for flexible relocation and fixation of the equipment. Working in conjunction with a height adjustment mechanism, a laser cladding repair mechanism, and a cooling mechanism, it completes automated laser cladding repair of turbine runner blades. A first servo motor drives a first screw to rotate, causing a lifting plate to slide vertically along a limit rod, adjusting the working height of the laser cladding repair mechanism to adapt to the repair needs of blades of different specifications. The limit rod guides and limits the lifting plate. The device is mounted on the vehicle body. The laser source transmits laser energy to the cladding head via optical fiber. A dual-cylinder powder feeder delivers repair powder to the cladding head through a powder feeding pipeline. Simultaneously, a robotic arm drives the cladding head to move flexibly at multiple angles, performing laser cladding welding repair on the damaged areas of the turbine runner blades. A chiller, in conjunction with a circulating pump, delivers cooling water into the cooling shell through the first circulation pipe. A spiral guide plate extends the cooling water flow path and improves heat exchange uniformity, effectively removing the high temperatures generated by the cladding head. The cooled water, after absorbing heat, returns to the chiller through the second circulation pipe for continuous cooling, ensuring the stable operation of the cladding head. The system utilizes a dual-axis motor, transmission rod, and bevel gear to drive a second screw to rotate, causing a sliding plate to slide vertically along a guide rod. This allows the axle with the traveling wheels and a U-shaped plate to extend from the clearance opening at the bottom of the vehicle body, enabling the equipment to be moved to the ground. A conductive slip ring prevents wiring tangling during turning and ensures stable power supply to the drive motor. The drive motor, via a first gear, drives the axle and traveling wheels to rotate. After moving to the working position, it reverses the drive to retract the traveling wheels into the vehicle body. Anti-slip pads at the bottom of the vehicle body ensure stable placement of the equipment. A second servo motor, via a second gear, drives a vertical shaft to rotate, adjusting the orientation of the traveling wheels and thus the direction of movement of the equipment. The clearance opening allows for the unfolding and retraction of the traveling wheels, while the anti-slip pads enhance the stability of the equipment. A laser radar on the cooling shell can scan the damaged area of the blade in real time, collecting repair location data and feeding it back to the control module. This allows for real-time matching of cladding operation parameters, ensuring repair accuracy. The entire process achieves automated, high-precision, and mobile blade cladding repair. The equipment is uniformly controlled by a control module inside the support, with a WiFi module supporting wireless operation. A lithium battery powers the equipment, and a charging port can replenish the power. Attached Figure Description

The axle 29 with the traveling wheel 30 and the U-shaped plate 28 extend from the clearance opening 36 at the bottom of the vehicle body 1, so that the equipment can be moved to the ground. The conductive slip ring 33 can prevent the wires from getting tangled during the turning process and ensure a stable power supply to the drive motor 31. The drive motor 31 can drive the axle 29 and the traveling wheel 30 to rotate through the first gear 32.

[0030] The working principle of the laser cladding repair equipment for turbine runner blades provided by this invention is as follows: The vehicle body 1 carries the entire working structure. The equipment can be flexibly moved and fixed through the retractable and movable mechanism. It works in conjunction with the height adjustment mechanism, laser cladding repair mechanism and cooling mechanism to complete the automated laser cladding repair of the turbine runner blades. The dual-axis motor 23 drives the second screw 21 to rotate through the transmission rod 24 and bevel gear 25, causing the sliding plate 22 to slide vertically along the guide rod 26, so that the wheel axle 29 with the traveling wheel 30 and the U-shaped plate 28 extend from the clearance opening 36 at the bottom of the vehicle body 1, realizing the ground movement of the equipment.

The drive motor 31 can drive the wheel axle 29 and the traveling wheel 30 to rotate through the first gear 32. After moving to the working position, it reverses the drive to retract the traveling wheel 30 into the vehicle body 1, and the anti-slip pad 37 at the bottom of the vehicle body 1 ensures the stability of the equipment. During the repair operation, the first servo motor 5 on the U-shaped frame 3 drives the first screw 4 to rotate, causing the lifting plate 6 to slide vertically along the limit rod 7, adjusting the working height of the laser cladding repair mechanism to adapt to the repair needs of different blade specifications. Subsequently, the laser light source 10 on the vehicle body 1 transmits laser energy to the cladding head 9 through the optical fiber 11, and the double-cylinder powder feeder 12 delivers the repair powder to the cladding head 9 through the powder feeding pipeline 13. At the same time, the robotic arm 8 drives the cladding head 9 to move flexibly at multiple angles to perform laser cladding welding repair on the damaged position of the turbine runner blade. The lidar 20 on the cooling shell 14 can scan the damaged area of the blade in real time, collect the repair position data, and feed it back to the control module 38 to match the cladding operation parameters in real time, ensuring repair accuracy. The entire process realizes automated, high-precision, and mobile blade cladding repair operation. During the repair process, the cooling mechanism continuously cools the equipment. The chiller 16 works in conjunction with the circulating pump 17 to send cooling water into the cooling shell 14 through the first circulating pipe 18. The spiral guide plate 15 extends the flow path of the cooling water and improves the heat exchange uniformity, fully removing the high temperature generated by the cladding head 9. The cooling water after absorbing heat flows back to the chiller 16 through the second circulating pipe 19 for circulating cooling, continuously ensuring the stable operation of the cladding head 9. The device is uniformly controlled by the control module 38 inside the support 2, the WiFi module 39 supports wireless control, the lithium battery 40 powers the device, and the charging interface 41 can replenish the power.
