Problems solved by technology

The above-mentioned existing technical solutions are not very operable. When heating the wheels, it is impossible to ensure that only the wheels are heated and the heat transmitted by the drive pins is not guaranteed. The impact method is easy to cause the transmission pin to fly off, causing the danger of injury

Abstract

The invention discloses a dismantling device for a transmission pin of a locomotive wheel, which comprises: a base, a rotatable support seat, a limit bracket and a hydraulic device. The rotatable support seat includes a fixed part fixed relative to the base and an annular rotating part rotatable relative to the base; the fixed part is provided with a fixed column, and the annular rotating part is sleeved on the fixed column to rotate relative to the fixed part; The limit mechanism is set on the fixed column of the locomotive; the limit bracket is set on the base to limit the displacement of the locomotive wheel in the axial direction; the limit mechanism is located on the extension line of the force direction of the hydraulic device; the hydraulic device and the transmission pin The joint is provided with a disassembly assembly. The dismantling device of the locomotive wheel transmission pin of the present invention is easy to disassemble and has strong operability; it can quickly and non-destructively disassemble the wheel transmission pin, and the disassembly efficiency is high; the dismantled transmission pin is guaranteed to be free from deformation; the personal safety of the operators is ensured; and the maintenance cost of the electric locomotive is reduced .

Description

technical field [0001] The invention relates to the technical field of electric locomotive equipment, and more particularly, relates to a device for dismounting a locomotive wheel transmission pin. Background technique [0002] The transmission pin of the electric locomotive wheel needs to be disassembled during maintenance, and it is necessary to ensure that the disassembled transmission pin has no deformation and can be recycled. [0003] In the prior art, the wheel is heated using the principle of thermal expansion and cold contraction, so that the mounting hole of the wheel transmission pin is enlarged, and at the same time, a sledgehammer is used to cooperate with the transmission pin to disassemble it. The above-mentioned existing technical solutions are not very operable. When heating the wheels, it is impossible to ensure that only the wheels are heated and the heat transmitted by the drive pins is not guaranteed. The hitting method is easy to cause the transmission...
