Embodiment 1

[0043] Provide a 300kW power level hydrogen energy power catenary maintenance work vehicle for railways:

[0044] The maximum operating speed is 120km / h, the weight of the whole vehicle is about 58 tons, the minimum curve radius can pass 100m, and the cruising range can reach more than 700km.

[0045] Operating equipment suitable for tunnel full-section and sound barrier maintenance;

[0046] Through the integration scheme of a high-power hydrogen fuel cell system on the car, the weight of the car is less than 58t, and the length of the car meets the curve radius of 100m. At the same time, the vehicle limit complies with GB146.1 "Standard Gauge Railway Limit Part 1 Locomotives According to the provisions of "Vehicle Limits", it has good stability, safety and good maintenance performance.

[0047] Ensure the safety of hydrogen energy-powered catenary maintenance vehicles.

[0048] A hydrogen energy powered catenary maintenance vehicle for railways includes: a car shed 1 and a...

Embodiment 2

[0097] The bottom of the vehicle frame 10 is provided with a braking system 15, which is composed of a CAB-B braking system, a resistance braking system and a basic braking device, and can realize air-electric interlocking control.

[0098] When the electric brake is applied during normal driving, the CCU controls and drives the air-electric interlock valve to act, and the normal air brake of the gate is removed; when the emergency brake is applied through the gate, or the emergency brake button is pressed, or the emergency Stop button, or when the brake pressure of the small brake is greater than 90KPa, the system will automatically cut off the electric brake.

Abstract

The invention provides a hydrogen energy power overhead line system maintenance operation vehicle for a railway. The hydrogen energy power overhead line system maintenance operation vehicle for the railway comprises a vehicle shed, a vehicle frame and a hydrogen fuel cell system, wherein the hydrogen fuel cell system comprises a hydrogen storage system, a protective cover, a fuel pile, an intake-exhaust system, a heat dissipation system, a control system and a hydrogen supply system. According to the hydrogen energy power overhead line system maintenance operation vehicle for the railway, the problems of emission pollution and noise pollution of a traditional internal combustion vehicle are solved, the problem that the endurance mileage of a pure battery vehicle is short is solved, and integrated application of a high-power hydrogen fuel battery system on the overhead line system operation vehicle is achieved; a foundation is provided for application of the hydrogen fuel cell system on other track engineering machinery, the hydrogen fuel cell system can extend to the upper part of a contact network, the back side of a stand column and other higher and farther positions, and the maintenance operation of an area A, an area B, an area C and an area D of the overhead line system is met; meanwhile, tunnel wall maintenance can be considered, and the advantages of large working platform space and large load capacity are achieved.

Description

technical field [0001] The invention relates to the field of track engineering, in particular to a hydrogen energy-powered catenary maintenance vehicle for railways. Background technique [0002] At present, in order to solve the problem of diesel engine emission pollution and noise pollution in tunnels, catenary operation vehicles at home and abroad mostly use internal combustion + battery hybrid power mode, internal combustion power is used for traction outside the tunnel, and battery power is used for operation in the tunnel. Complicated, the length and weight of the vehicle are greatly increased, and it is suitable for heavy-duty operating vehicles. In addition, the "internal combustion + battery" hybrid traction only achieves zero emissions and zero pollution on some road sections, while the traction method powered by pure batteries is only suitable for short distances And working conditions with better line conditions, such as urban rail transit. [0003] As a clean e...
