Fig. 1 and 2 show a wheel-set-up lifting drive apparatus comprising: a trailer 1000 and a drive 2000. The trailer 1000 includes a body 1100, wheel drivers (not shown), drive wheels 1200, and rollers 1300. The wheel driver is installed in the vehicle body 1100 and drives the driving wheel 1200 to move, wheel arms 1400 extending horizontally and rearwards are fixed to both sides of the vehicle body 1100, rollers 1300 are connected to the end portions of the wheel arms 1400, and guide rails 1500 extending in the vertical direction are fixed to both sides of the vehicle body 1100. The driving device 2000 includes a case 2100, a jacking device (not shown), a lifting device 2300 and a support assembly 2400. Sliders 2110 are fixed to both sides of the case 2100, and the sliders 2110 are engaged with the guide rails 1500. The fixed part of the jacking device is positioned in the case 2100 and fixed on the case 2100, and the movable part of the jacking device passes through the top surface of the case 2100 and is connected to the lifting device 2300. The support assembly 2400 is supported on the housing 2100 and is capable of moving up and down relative to the housing 2100.
When the device is used for pushing and lifting wheel pairs, firstly, a wheel driver on the trailer 1000 drives a driving wheel 1200 to rotate to drive a roller 1300 to rotate, so that the driving device 2000 is conveyed to the side of the wheel pairs to be pushed and lifted; the lifting device 2300 is then aligned with the wheels of the wheel pair to be lifted, the support assembly 2400 is placed on the work ground, the height of the housing 2100 relative to the work ground is adjusted, and the lifting device drives the lifting device 2300 to move upwardly, thereby lifting the wheel pair in the opposite direction. The problem that the driving device 2000 is not easily moved can be solved by providing the trailer 1000 on the driving apparatus. In addition, the distance between the case 2100 and the work floor is adjusted by the support assembly 2400, so that the distance that the moving part of the jacking device needs to move can be changed, and the moving distance can be kept within a relatively reliable and stable range. The slider 2110 is matched with the guide rail 1500, so that the moving direction of the box 2100 can be accurate, and the situation that the moving process is inclined to influence the reliability of jacking equipment is avoided.
As shown in fig. 3 and 4, the lifting device 2300 includes an upper lifting mechanism 2310 and a lower lifting mechanism 2320.
