A hand-controlled electric rail car for bridge maintenance

Abstract

The invention provides a hand-controlled electric rail car for bridge overhaul. The electric rail car includes a body, a chassis and an electrical drive system, the chassis is located at the bottom ofthe vehicle body, the electrical drive system is arranged in the vehicle body in the middle of the bottom plate, a main cab, an auxiliary cab and storage space are formed in the vehicle body, a windshield is arranged on the vehicle body, the chassis comprises a load-bearing frame, a drive axle, a driven axle and a brake system, the driving axle and the driven axle are arranged on two sides of theload-bearing frame, a brake system is arranged on the driving axle or / and the driven axle, the bridge overhaul electric rail car further comprises main and auxiliary operation panels that are respectively located in the main cab and the auxiliary cab, and the main and auxiliary operation panels are respectively provided with a manual control system which is respectively connected with an electricdrive system and a service brake system, so as to solve the defects of narrow space, inconvenient operation and difficult movement of the existing rail car.

Description

technical field [0001] The invention relates to the technical field of electric rail cars, in particular to a hand-controlled electric rail car for bridge maintenance. Background technique [0002] At present, under the background of technology-led, innovation-driven, and intelligent manufacturing, my country's large-scale bridge construction has made remarkable achievements. New materials, new processes, and new technologies are being used more and more. A new type of steel box girder is being increasingly More and more applications are applied to various types of bridge construction and road pavement. However, the internal tunnel structure space of the steel box girder of this type of bridge is small and the internal environment is poor, which makes daily maintenance and inspection extremely difficult. It is inconvenient to carry tools manually, and the operation is labor-intensive. The working environment is poor and the working cycle is long; there are space defects in the...

Problems solved by technology

[0002] At present, under the background of technology-led, innovation-driven, and intelligent manufacturing, my country's large-scale bridge construction has achieved world-renowned achievements, and more and more new materials, new processes, and new technologies are being used. More and more applications are applied to various types of bridge construction and pavement pavement. However, the internal tunnel structure space of such bridge steel box girders is small and the internal environment is poor, which makes daily maintenance and overhaul extremely difficult. It is inconvenient to carry tools manually, and the work is labor-intensive. The working environment is poor and the work cycle is long; there are space defects in the foot control of traditional bridge tunnel maintenance vehicles. If the traditional foot control scheme is used, it will make driving very difficult, difficult to operate, and there are potential safety hazards, and effective operations cannot be carried out. There is no relevant report on the research case of this kind of hand-controlled bridge and tunnel maintenance vehicle;

[0003] For example, Chinese patent CN102605714B discloses a bridge track electric maintenance vehicle, but this kind of maintenance vehicle adopts a traditional control method. On the one hand, it is provided with a power system, on the other hand, it is provided with a parking brake system, and the two parts are respectively controlled. control, which leads to the extremely small internal space of the rail car, which is inconvenient for personnel to enter and exit, and the tools that can be carried are also less, and the comfort is poor

[0004] Therefore, due to the special internal structure of the bridge, other maintenance vehicles cannot enter the work. How to ensure the maintenance and maintenance of steel box girder bridge tunnels and solve the problem of space defects in the foot control of maintenance vehicles in bridge tunnels is an urgent research problem;

[0005] Moreover, the driving system and braking system of the current electric maintenance vehicle are not accurate enough, and it is easy to cause danger when moving inside the narrow bridge body
