Technical Field

[0001] This utility model belongs to the field of vehicle machinery maintenance technology, and in particular relates to a vehicle brake wheel replacement device. Background Technology

[0002] Metallurgical enterprises use overhead cranes and other lifting equipment for hoisting and transportation, which are essential equipment in the production process. Taking a 225-ton overhead crane as an example, the crane's track is 29 meters above the ground. When the crane's wheel sets reach the end of their service life, they need to be replaced online. First, the old wheel sets are moved outside the crane's main beam and then lifted off using cranes or other equipment.

[0003] Chinese Patent Publication No. CN219113969U discloses an auxiliary replacement device for vehicle wheel sets, comprising a guide assembly, a telescopic rod, a telescopic sleeve, a side rod, a lead screw, and a support wheel. The guide assembly includes a first guide wheel, a first wheel axle, a second guide wheel, a second wheel axle, a wheel rod, and a connecting rod. The connecting rod includes an outer connecting rod, an inner connecting rod, and a connecting bolt for connecting the outer and inner connecting rods. One end of the inner connecting rod is fixed to one side of the telescopic rod, and the connecting bolt passes through the outer connecting rod and connects to the other end of the inner connecting rod. The first guide wheel is fixed to the bottom of the outer connecting rod via the first wheel axle, and the second guide wheel is fixed to the bottom of the inner connecting rod via the second wheel axle. The bottom of the second guide wheel is connected to one end of the wheel rod, and the other end of the wheel rod is fixed to the side wall of the telescopic rod.
