[0042] When a mining dump truck's steering knuckle assembly fails, it is brought to the site for repair. After the tire is removed, the walking mechanism 1 of the device identifies the location of the steering knuckle assembly through the laser navigation device and quickly moves to a suitable position in front of the steering knuckle assembly. The six-axis action mechanism 9 controls the front and rear, left and right distance movement, rotation angle or front and rear swing of the clamping device 8 according to the specific situation on site, so that the wheel hub clamping claw 13 is accurately clamped on the steering knuckle assembly hub, and then the supporting height of the steering knuckle supporting assembly 16 is adjusted so that the tail end of the steering knuckle assembly is close to the steering knuckle supporting assembly 16, so as to maintain the overall stability of the steering knuckle assembly and complete the clamping and fixation of the steering knuckle assembly.

[0043] The pin disassembly and assembly mechanism 10 is driven to disassemble the pin of the steering knuckle assembly. First, the pin disassembly and assembly mechanism 10 adjusts the position and angle up and down, left and right, front and back through the moving device 22, the lifting device 23, and the flipping device 24, so that the inner hole coaxiality measuring device corresponds to the position of the pin, and then the inner hole coaxiality measuring device lifting mechanism 26 is driven to drive the inner hole coaxiality measuring device 27 to rise and fall to a suitable position, and the coaxiality is detected by the laser sensor 28. After the detection is completed, the main pin is disassembled by the disassembly and assembly manipulator 25. Finally, the walking mechanism 1 and the working mechanism 2 are controlled to place the disassembled steering knuckle assembly at the placement location.

[0044] The device can also realize the installation process of the steering knuckle assembly of the mining dump truck. First, the device is moved to the location where the steering knuckle assembly is placed, and the six-axis action mechanism 9 is driven to control the wheel hub clamping claw 13 and the steering knuckle jacking assembly 16 of the clamping device 8 to clamp and fix the steering knuckle assembly, and the steering knuckle assembly is moved to the frame position for installation, and the pin disassembly and assembly mechanism 10 is driven to complete the kingpin grabbing through the disassembly and assembly manipulator 22, and the inner hole coaxiality measuring device 24 is controlled to perform the coaxiality detection of the steering knuckle pin hole and the beam pin hole.
