Wheel set lifting mechanism for railway locomotive wheels

Abstract

The invention discloses a wheel set lifting mechanism for railway locomotive wheels. The wheel set lifting mechanism comprises a base, wherein a sliding seat is connected to the base in a sliding mode, an adjusting mechanism is arranged between the sliding seat and the base, a sliding groove is formed in the sliding seat, two sliding blocks are connected to the interior of the sliding groove in asliding mode, and a servo motor is fixedly connected to the sliding seat; and a limiting mechanism comprises U-shaped grooves formed in a first U-shaped supporting plate and a second U-shaped supporting plate, a reset plate is connected to the interior of each U-shaped groove in a sliding manner, a plurality of first springs are fixedly connected between the reset plates and the inner bottoms of the U-shaped grooves, and two guide columns are fixedly connected to the upper ends of the reset plates. The wheel set lifting mechanism for the railway locomotive wheels is reasonable in structure, not only can wheel sets be stably clamped, but also axles can be stably clamped, the stability of the supported axles is guaranteed, manual operation of workers is not needed, the labor amount of the workers is greatly reduced, and the safety is higher.

Description

technical field [0001] The invention relates to the technical field of lifting devices, in particular to a lifting mechanism for railway locomotive wheels. Background technique [0002] The wheel set is the part of the rolling stock that is in contact with the rail, and consists of two left and right wheels that are firmly pressed on the same axle. The role of the wheel set is to ensure the running and turning of the rolling stock on the rails, bear all the static and dynamic loads from the rolling stock, transmit it to the rail, and transfer the load caused by the uneven track to the parts of the rolling stock. In addition, the driving and braking of the rolling stock also work through the wheelset.

AI Technical Summary

Problems solved by technology

[0003] Existing railway locomotives and subway vehicles need to support the wheel sets to facilitate the maintenance of the wheels when performing maintenance on the opposite wheel sets; It makes the hoisted wheel set shake, which is inconvenient for maintenance and has certain dangers; the other is supported by a support plate, which is more stable than the gantry hoisting, but the axle is still manually fixed and limited during support, which increases The workload of the staff is reduced, so we designed a lifting mechanism for railway locomotive wheels to solve the above problems
