Technical Field
The invention particularly relates to a walking type wheel shaft press-mounting machine, and belongs to the technical field of mounting and dismounting tool equipment.
Background
The interference fit, i.e. depending on the interference value of the shaft and the hole, produces an elastic pressure between the surfaces of the parts after assembly, so that a tight coupling is obtained. Mounting and dismounting parts with small interference fit by a common hammering method; the installation and the disassembly of parts with large interference fit are commonly carried out by a press jacking method and a temperature difference method.
The wheel and the shaft of the cart traveling wheel of the bridge crane are matched in a large interference fit manner; the wheel and the shaft of the trolley traveling wheel of the bridge crane are matched with each other in a large interference fit mode. When repairing bridge cranes, oil presses are required for mounting and dismounting the wheels and the axles. A large-scale factory has dozens of workshops and hundreds of bridge cranes, but only has one or two fixed oil presses, and the fixed oil press for pressing and mounting the wheels of the bridge cranes is shown in a figure 1. Hundreds of bridge cranes are distributed over various workshops, warehouses and stock yards. When the equipment maintenance worker repairs the bridge crane and needs to install and disassemble the wheels and the shafts, the fixed oil press is at a corner of a certain remote workshop, the fixed oil press is inconvenient to carry, the utilization rate is low, and the cost of the large oil press is high.

Preferably, the number of the pull rods is two, and the pull rods are uniformly distributed at four corners to form a square.
Compared with the prior art, the walking type wheel shaft press-mounting machine has the beneficial effects that:
1. the free wheel shaft press-mounting machine is extremely low in cost, the manufacturing cost of a fixed oil press for press-mounting the traveling wheels of a bridge crane is 80 ten thousands, and the manufacturing cost of the free wheel shaft press-mounting machine is less than 1 ten thousands.
2. The moving type wheel shaft press-mounting machine is mainly characterized by small equipment volume, convenient carrying and transportation, assembly and use, convenient transportation of a battery tricycle for equipment maintenance personnel, convenient storage of parts which can be disassembled when not in use, capability of assembling and disassembling a wheel shaft in large interference fit, convenience in disassembling a burned bearing and convenience in disassembling other rusted parts.
