A frame structure switchable track type maintenance trolley

Abstract

The invention discloses a frame-structure switchable track-type overhaul trolley, which belongs to the field of track overhaul vehicles. The device adopts a frame structure, which is similar to a group of movable parallelograms and can maintain a long time between the track drive device and the rotating connecting rod. Maintain a horizontal state, and because the weight of the frame structure device is reduced, track switching can be performed better, and the sensor on the rotating link is kept stable by installing a sensor stabilization device on the rotating link , to prevent damage to the sensor due to excessive deflection angle during the rotation of the device.

Description

technical field [0001] The invention relates to the field of track maintenance vehicles, in particular to a frame-structured switchable track-type maintenance trolley. Background technique [0002] With the rapid development of society and the continuous improvement of science and technology, the emergence of high-speed railways has made railway travel the preferred mode of travel for most people. Railway transportation is a land transportation method. The traditional way of traveling on rails is steel wheels, but in a broad sense, railway transportation still includes non-steel wheels such as maglev trains, cable cars, and cableways, or rail transportation. Rails can provide an extremely smooth and hard medium for train wheels to move on. It rolls with minimal friction to make the people on it feel more comfortable, and it also saves energy. If properly configured, rail transportation can save 50 to 70% of energy compared to road transportation when carrying the same weight...

[0002] With the rapid development of society and the continuous improvement of science and technology, the emergence of high-speed railways has made railway travel the preferred mode of travel for most people. Railway transportation is a land transportation method. The traditional way of traveling on rails is steel wheels, but in a broad sense, railway transportation still includes non-steel wheels such as maglev trains, cable cars, and cableways, or rail transportation. Rails can provide an extremely smooth and hard medium for train wheels to travel. It rolls with minimal friction to make the people on it feel more comfortable, and it also saves energy. If properly configured, rail transport can save 50 to 70% of energy compared to road transport for the same weight. Moreover, rails can Evenly disperse the weight of the train, so that the load capacity of the train is greatly improved. As we all know, the railway is composed of rails connected by bolts. With the growth of time, the rails sometimes become damaged and loose. If they are not repaired in time, they will It has a great impact on the running of the train, so it is necessary to carry out regular maintenance on the track;

[0003] At present, most of the track maintenance trolleys can only operate in one of the single-track or double-track states, and cannot switch freely. There is a lack of a single-track and double-track maintenance trolley that can be freely converted
