Problems solved by technology

[0008] The purpose of the present invention is to provide a railway track cleaning and maintenance device, which can solve the problem that the existing track cleaning equipment is cumbersome to operate when avoiding trains, and a lot of time is wasted; after avoiding, the distance between the train and the high-speed train is too small, which is likely to cause potential safety hazards ; and issues such as the inability to switch between modes of driving along railroad tracks and on the ground

other Embodiment approach

[0054] In other embodiments, the linear telescoping unit can also adopt structures such as electric push rods and cylinders, which can be selected by those skilled in the art, provided that the usage requirements can be met.

[0055] Of course, those skilled in the art can also use other technical means than the linear telescopic unit to adjust and fix the distance between the first frame 1 and the second frame 2 in the vertical direction, so I won’t go into details here. .

[0056] In order to realize the walking function of the vehicle frame on the railway track and the ground, the present embodiment sets track wheels 10 and road wheels 8, and the number of the track wheels 10 and the road wheels 8 is multiple, and the walking direction of the road wheels 8 It can be adjusted to realize steering when the vehicle frame walks along the ground, and the rail wheel 10 and the road wheel 8 are driven by a power mechanism to realize rotation.

[0057] Specifically, the structural ...

Abstract

The invention relates to a railway track cleaning and maintaining device, including a vehicle frame, wherein the vehicle frame comprises a first vehicle frame and a second vehicle frame which are connected with each other; the first vehicle frame is arranged under the second vehicle frame; track wheels are installed on the lower portion of the first vehicle frame; walking wheels are installed on the lower portion of the second vehicle frame; the track wheels can drive the vehicle frame to travel along a railway track, and the walking wheels can drive the vehicle frame to travel along the ground; and the distance value of the first vehicle frame and the second vehicle frame in the vertical direction can be adjusted, so that the distance between the lowest point of the track wheels and the lowest point of the walking wheels in the vertical direction is changed by the same value.

Description

technical field [0001] The invention belongs to the technical field of railway maintenance equipment, and in particular relates to a railway track cleaning and maintenance device. Background technique [0002] Railway tracks are referred to as rails for short, and are used to support the running of trains along the direction of rail laying. Railway tracks usually consist of two parallel steel rails that are fixed to sleepers. The rail is an I-shaped structure, and the upper end surface of the upper wing plate is in contact with the middle rail wheel of the train and bears pressure. Under the long-term extrusion friction, it is always in a polished state; The side is not in contact with the rail wheel, so it cannot be squeezed and polished. During long-term use, it is prone to rust and affects the structural strength and stability of the rail. At the same time, there may be rubbish and debris on both sides of the rail or on the rail, which will be involved in the bottom of ...
