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

Abstract

The invention discloses a lifting mechanism for railway locomotive wheels, which comprises a base, a sliding seat is slidably connected to the base, an adjustment mechanism is arranged between the sliding seat and the base, and a sliding seat is provided on the sliding seat. Two sliding blocks are slidably connected in the sliding groove, and a servo motor is fixedly connected to the sliding seat; the limit mechanism includes a U-shaped groove arranged in the first U-shaped support plate and the second U-shaped support plate A reset plate is slidably connected in the U-shaped groove, a plurality of first springs are fixedly connected between the reset plate and the inner bottom of the U-shaped groove, and two guide columns are fixedly connected to the upper end of the reset plate. The invention has a reasonable structure, not only can stably support the wheel set, but also can stably clamp the axle to ensure its stability after being supported, without manual operation by the staff, greatly reducing the workload of the staff, and More security.

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. [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 cert...
