Detailed Description
In order to clearly understand the technical contents of the present invention, the following embodiments are specifically illustrated in detail.
the utility model discloses a be applied to portable emergency rescue equipment of intelligent rail trolley-bus comprises 4 parts such as oil tank, pump station, energy storage ware, proportional valve group. Wherein:
The oil tank is used for storing oil and supplying oil;
The pump station is used for converting mechanical energy into hydraulic energy;
The energy accumulator is used for storing hydraulic energy;
The oil tank, the pump station and the energy accumulator provide power for the axle steering;
the proportional valve is used for controlling the steering of the wheels.
after a hydraulic system of a certain axle of the vehicle breaks down, the rescue equipment is connected into the trackless guide system through the hydraulic pipeline and the electric wire harness, and two axle oil cylinders can be controlled simultaneously. Provides a complete hydraulic power and control system for one carriage of the intelligent rail electric vehicle,
because the portable emergency rescue equipment needs to consider the pipeline connection and the electrical connection with the original vehicle, each external pipeline connection interface and each electrical connection interface need to be reserved on the original vehicle.
The external pipeline connecting interface is mainly characterized in that an emergency oil line pipeline interface is reserved in front of each axle oil cylinder, the oil line interface is arranged at a position convenient for installation and operation in a vehicle, and the oil line interface is generally a 24-degree standard joint of a hydraulic system.
The external electrical connection interface comprises a proportional valve group connector plug, a pump station low-voltage driving control plug and a pump station 380V high-voltage connector plug.
The portable emergency rescue equipment has the following functions:
a) when the hydraulic system of the car body works normally
See the body hydraulic system 100 in fig. 2. When the vehicle normally runs, the steering control is realized through the original trackless guiding hydraulic system of the vehicle body.
The body hydraulic system 100 mainly includes an electrical control box 103, proportional valve groups 101 and 102, an oil tank 105, a pump station 106, an accumulator 107, and the like. The electrical control box 103 is connected to the proportional valve block 101 and the proportional valve block 102 through proportional valve block connector plugs XT1 and XT2, respectively, and to the pumping station 106 through the low voltage control plug 104. The pumping station 106 is connected to the vehicle battery via a 380V high voltage connector plug 108.
the working principle is as follows: the oil tank 105 is used for storing oil and supplying oil; the electric control box 103 controls the pump station 106 to pressurize the oil, converts mechanical energy into hydraulic energy, and the accumulator 107 stores the hydraulic energy. When the vehicle body steering needs to be controlled, the electric control box 103 controls the proportional valve group 101 and the proportional valve group 102 to steer the wheels, and the accumulator 107 releases hydraulic energy to provide power assistance for the wheel steering.
b) when the hydraulic system of the car body is in failure
See portable emergency rescue device 200 in fig. 2. When a hydraulic system of one axle of the intelligent tramcar fails and cannot drive, the portable emergency rescue equipment 200 is connected.
portable emergency rescue apparatus 200 includes proportional valve sets 201 and 202, a fuel tank 205, a pump station 206, and an accumulator 207.
The operation method comprises the following steps: the hydraulic pipelines at the two ends of the fault axle oil cylinder are disconnected, the emergency oil line pipeline interfaces reserved in front of the axle oil cylinders are connected into the hydraulic system 200 of the rescue equipment, and meanwhile, the original hydraulic oil line is blocked to prevent hydraulic leakage. The electric plugs of the oil tank 105, the pump station 106, the proportional valve blocks 101 and 102 and the like in the original axle, which are connected with the electric control box 103, are disconnected, the proportional valve blocks 201 and 202 in the rescue equipment 200 are respectively connected with the electric control box 103 through electric harnesses XT3 and XT4, the pump station 206 in the rescue equipment 200 is connected with the electric control box 103 through a plug 204, and the pump station 206 in the rescue equipment 200 is connected with a storage battery on the automobile through a plug 208. Thereby, the rescue apparatus 200 is controlled by the onboard electric control box 103 to continue the wheel steering function.
The portable emergency rescue equipment can also be provided with an electric control box. When the electric control box is arranged, the electric control box in the emergency rescue equipment directly controls the proportional valve group, the oil tank, the pump station and the energy accumulator in the emergency rescue equipment to perform the wheel steering function without the help of the electric control box on the vehicle.
