Description
Technical Field
The invention belongs to the technical field of port tractors, and particularly relates to a fuel cell tractor with a hydrogen storage tank placing frame.
Background
Under the trend of increasingly strict environmental protection requirements, medium and heavy vehicles also face the problems of energy conservation and environmental protection. At present, a tractor used in a port is mainly driven by a diesel engine, a large amount of air pollutants and greenhouse gas are discharged in the working process, the energy conversion rate is low, and the energy loss is large.
The fuel cell vehicle is not provided with traditional diesel engine, transmission, oil tank and other parts, and mainly comprises a fuel cell stack, a power storage battery, a high-voltage hydrogen storage tank, a DC/DC converter, a driving motor, a power control unit and the like, wherein the fuel cell stack is a core component. The hydrogen in the galvanic pile reacts with the oxygen to generate electric energy, and the electric energy is connected with the power storage battery in parallel after impedance matching and voltage conversion of the DC/DC converter, and the electric energy is jointly output to the driving motor. The driving motor converts the electric energy into mechanical energy to drive the vehicle. When the automobile runs, a fuel cell system is mainly adopted to provide electric power, and a power storage battery mainly plays roles in peak regulation, capacity increment and energy recovery. When the automobile is in an acceleration and uphill state, the power storage battery is used as an auxiliary power supply to provide power; when the automobile is in a downhill and deceleration state, the power storage battery recovers the surplus electric energy of the fuel cell. The hydrogen fuel cell heavy truck currently adopts a 35MPa hydrogen supply system, and the hydrogen supply systems are uniformly distributed behind a cab due to the structural arrangement of the whole truck.
At present, the increase of the endurance mileage of the hydrogen fuel cell vehicle is realized by increasing the number of gas cylinders, and the tractor cannot place a sufficient hydrogen storage tank at the position of an original diesel tank because the wheel base is smaller, so that the endurance requirement of the tractor is met, and the domestic hydrogen fuel cell tractor adopts a mode of cab rear side suspension. The layout mode of the hydrogen supply system has potential safety hazard. Firstly, the hydrogen storage tank blocks a rear window of a cab in a rear suspension mode of the cab, and the view of a driver looking backwards is influenced; secondly, the front part of the truck is the power part such as an engine and the like, and can cause serious injury to a driver when collision occurs, so that the existing automobile companies adopt a cab backward moving technology, namely the truck is allowed to move backward when the truck is subjected to frontal collision, so that the impact of the frontal collision can be buffered, and the damage to the driver can be reduced. But this is a passive security technique. Therefore, the spread of the harbor fuel cell tractor is affected.
With the environmental protection requirement of energy saving and emission reduction, a new placement mode of the hydrogen storage tank structure is to be pushed out aiming at the fuel cell tractor so as to meet the requirement of safe transportation of port logistics.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a fuel cell tractor with a hydrogen storage tank placing frame, which can solve the problem of great potential safety hazard caused by the fact that the hydrogen storage tank is placed behind a cab.

The cross section of the hydrogen storage tank placing frame is in a shape of inverted concave, the hydrogen storage tank placing frames on two sides are divided into an upper layer and a lower layer, and the hydrogen storage tank placing frame is divided into a front group of frame units and a rear group of frame units.
The whole width of both sides of hydrogen storage tank rack is less than or equal to the reference surface of tractor body width.
The distance between the frame beams of the hydrogen storage tank placing frame is 1-2cm larger than the diameter of the hydrogen storage tank.
And the hydrogen storage tanks in the hydrogen storage tank placing frame are respectively converged into one path through distribution valves and are connected with the fuel cell through threaded hoses.
The stainless steel fixing band is characterized in that a rubber pad is arranged on the inner side of the stainless steel fixing band and fixed with the stainless steel fixing band through a bolt, and the stainless steel fixing band and the hydrogen storage tank are prevented from being abraded.
The stainless steel fixing band is connected with the hydrogen storage tank placing frame through a bolt.
Has the advantages that: compared with the prior art, the invention can solve the problem of great potential safety hazard caused by the fact that the hydrogen storage tank is placed behind the cab. When the front collision of the vehicle is avoided, the placement mode of the hydrogen storage tank positioned at the rear side of the cab can influence the backward movement space of the cab of the main engine, and the casualty probability of a driver is increased. Meanwhile, if the hydrogen storage tank is arranged behind the cab, when the collection truck participates in operation at a wharf, misoperation occurs easily in operations of a shore bridge and a factory bridge, so that the container is pressed to the head part of the tractor, hydrogen is leaked after being impacted and extruded, and fire and explosion happen. The device of the present invention eliminates the above-mentioned hidden danger.
