Wheel set lifting device for railway locomotive

Abstract

The invention discloses a lifting device for a wheel set of a railway locomotive, 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 groove is provided on the sliding seat. Two sliding blocks are slidably connected in the sliding groove, a servo motor is fixedly connected to the sliding seat, and a first screw is fixedly connected to the output end of the servo motor, and the first screw runs through the sliding seat and is connected to it in rotation. The end of the first screw rod opposite to the servo motor is fixedly connected with a second screw rod, and the second screw rod is rotatably connected with the inner wall of the sliding groove. The first screw rod and the second screw rod respectively pass through the two sliding blocks and are threaded connect. 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 wheel set lifting device for railway locomotives. 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 cer...

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 Therefore, we designed a railway locomotive wheel set lifting device to solve the above problems
