detailed description

Below in conjunction with Fig. 1 to Fig. 3, the utility model is described in detail.

A braking device for an electric locomotive, comprising a turbocharger 1, the air inlet of the turbocharger 1 is connected to the exhaust pipe of the electric locomotive through an air pipe, and a filter can also be installed on the air inlet of the turbocharger 1 Net for filtering exhaust gas. The air outlet of the turbocharger 1 communicates with the pressure accumulator 2 through the air delivery pipe; the exhaust port of the pressure accumulator 2 is connected with the cylinder 3 fixed on the vehicle body through the air delivery pipe; Air intake valve 21 is installed on the gas delivery pipe. The air delivery port of the cylinder 3 is located in the middle, and the left side and the right side of the cylinder 3 are respectively equipped with a left piston and a right piston, and the left piston and the right piston are respectively connected with a left telescopic rod 31 and a right telescopic rod 32, and the left telescopic rod 31 The end of the right telescopic link 32 is hinged on the bottom of the left rotating rod 4, the end of the right telescopic rod 32 is hinged on the bottom of the right rotating rod, the tops of the two rotating rods are hinged on the car body, and the middle part of the rotating rod 4 There are brake pads 5, and when the telescopic rod is stretched out, the brake pads 5 can be pressed against the wheels to realize braking. A return spring is also installed on the rotating rod 4, and an exhaust pipe is also installed on the cylinder 3, and an air outlet valve is installed on the exhaust pipe.

Further, the pressure accumulator 2 is also provided with a safety valve 23 .

Further, the pressure accumulator 2 is also provided with a pressure sensor 22 .

The above brake device for electric locomotive converts the exhaust gas into high-pressure gas through the turbocharger 1, and the high-pressure gas is stored in the pressure accumulator 2, and the user can maintain the air pressure in the pressure accumulator 2 through the safety valve 23. The pressure sensor 22 monitors the pressure in the pressure accumulator 2 in real time. When braking is needed, the intake valve 21 only needs to be opened, the high-pressure gas enters the cylinder 3 and pushes the left piston and the right piston to move to both sides, and the piston drives the lower part of the rotating rod 4 to rotate outward. Driven by 4, it abuts against the wheel to stop the rotation of the wheel and realize the effect of braking. When the brake stops, only need to open the outlet valve, the high-pressure gas in the cylinder 3 flows out, and the rotating rod 4 returns to its original position under the drive of the return spring, and drives the two telescopic rods and the two pistons to return. Braking by the braking device of the electric locomotive can obviously increase the braking force and shorten the idle time. The exhaust gas in the exhaust pipe is used to provide energy, which is energy-saving, environmentally friendly, safe and reliable.

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples, and changes, modifications, additions or replacements made by those skilled in the art within the essential scope of the present utility model are also acceptable.
