Description

Technical Field

[0001] This utility model relates to the field of engineering welding vehicles, and in particular to a range-extended engineering welding vehicle. Background Technology

[0002] With the adjustment of the global energy structure and the development of clean energy, oil and gas pipelines will play an increasingly important role in energy supply construction. In the future, oil and gas pipelines will develop towards diversification, intelligence, and environmental friendliness. Currently, oil and gas pipeline equipment mainly relies on heavy non-road construction machinery, and construction operations are mostly conducted in the field, resulting in a very low electrification penetration rate. Therefore, it is necessary to accelerate the application of electrification technology in project construction to achieve a win-win situation of energy conservation, emission reduction, and reduced construction costs.

[0003] The power requirements for welding engineering vehicles for both mobile lifting and power generation welding differ greatly. Traditional models select engines based on mobile requirements, but in actual use, power generation welding is the main function. This results in excessive engine power, low thermal efficiency, poor fuel economy, and fuel waste. Power generation is mainly used at 1500 rpm, resulting in a very low load rate.

[0004] Therefore, it is necessary to develop a new type of range-extended hybrid engineering welding vehicle to overcome the above problems. Utility Model Content

[0005] Purpose of the utility model: To address the shortcomings and defects of existing technologies, this utility model provides a range-extended engineering welding vehicle that integrates a range-extending engine, power battery, inverter, etc., into an independent power system and adds an installation interface for other transport vehicles. It can provide power for transport vehicles and also be used as an independent mobile power station. By utilizing the power battery, the energy generated when the machine is idling is recovered and stored, i.e., the battery is charged, thereby improving fuel utilization, achieving energy saving and emission reduction, and reducing construction costs.

[0006] Technical solution: The present invention relates to a range-extended engineering welding vehicle, characterized in that it includes an electric drive force and control system, a welding machine canopy, a gas cylinder lifting frame, an independent range extender power system, a folding boom, a cab, a hydraulic system, and a chassis; the electric drive force and control system, the welding machine canopy, the gas cylinder lifting frame, the independent range extender power system, the folding boom, the cab, and the hydraulic system are mounted on a platform above the chassis.

[0007] The independent range extender power system includes a range extender engine, a power battery, and an inverter.

[0008] The independent range extender power system is equipped with an interface for installation with other transport vehicles.

[0009] The independent range extender power system is located in the middle of the platform above the chassis.

[0010] The electric drive and control system, folding boom, cab, and hydraulic system are located on the left side of the independent range extender power system.

[0011] The welding machine shed and gas cylinder lifting frame are located on the right side of the independent range extender power system.

[0012] The hydraulic system includes a hydraulic oil tank and a main pump.

[0013] Beneficial Effects: Compared with existing technologies, this utility model has the following significant advantages: This utility model adopts a modular and standardized design, making reasonable use of platform space. It employs a range-extended power station module, allowing excess energy to be stored in the power battery as electricity when the mechanical equipment is in standby mode, improving fuel efficiency and reducing costs. The independent range-extended power module is an independent power supply module, placed within the vehicle, providing power to the entire vehicle, or it can be disassembled separately to serve as an independent generator set for independent power generation in the field for non-mobile equipment. It adopts a compact structure and layout: within a limited space, the range-extended power station module allows excess energy to be stored in the power battery as electricity, improving fuel efficiency and reducing costs, while also accommodating functions such as mobility, power generation, hoisting, and welding.
