2. Description of the Related Art In a conventional monorail, an air tank for accumulating and using air sent from a compressor on a frame is required separately from the frame. In that case, the frame frame made by processing the material pipe is used as a frame frame for mounting various parts of the main monorail such as engine, compressor, transmission, control box, etc. on its upper part and its lower part. It has been used as a drive wheel to be mounted on a vehicle, which has the following drawbacks. That is, the space occupied by the mounted air tank reduces the size of the limited space on the frame. The distance between the air tank and the air compressor becomes longer, and the pressure-resistant pipe connecting them becomes longer. For this reason, the pressure-resistant pipe is caught, so that damage is likely to occur, and further, the size of the fuel tank and other parts mounted thereon are restricted.

[0003]

The frame around the monorail is made of a pipe having an internal space in order to maintain the strength to withstand the gravity of load, twisting, etc. It aims to provide a monorail equipped with an EVA tank that uses the interior space of the. The internal space of the pipe itself used as a frame frame is sealed, and parts such as pressure control valve, drain cock, pressure switch, pressure hose connection port, etc. are installed in the frame frame and operated by engine power. It is used as an air tank for pressurized air sent from the compressor. A connection port may be provided anywhere around the air tank that also serves as a frame, and a pressure resistant pipe can be connected from anywhere, so by making it possible to connect to various air cylinders with the shortest pressure resistant pipe from that air tank to the air cylinder, The risk of damage due to hooking the pressure-resistant pipe is reduced, and the large fuel tank can be placed in the empty space in which the ethane above the frame retreats.

[Means for Solving the Problems]

 An air tank that also serves as a frame is created by sealing a pipe that has an internal space as a frame, and parts such as a pressure control valve, drain cock, pressure switch, pressure hose connection port, etc. are provided around this air tank. , Connect the connection port of the pressure resistant pipe that sends air from the compressor to the connection port provided in the air tank. One end of the pressure resistant pipe is provided at the connection port of this air tank, and the other connection port is provided at the connection port of the electromagnetic valve. Provide the other connection port of the pressure resistant pipe connected to each solenoid valve to each connection port of each air cylinder. That is, the other connection port of the pressure resistant pipe connected to each electromagnetic valve is connected to the connection port of each air cylinder of the tension cylinder, brake cylinder, throttle cylinder, and return cylinder. A pressure switch is installed at an appropriate position in the air tank, and when the engine is started, the compressor turns by the power of the engine to pump air into the air tank, and the pressure switch operates when the internal pressure of the air tank rises and reaches a certain pressure. Then, the power of the control circuit is input. By operating the button of the operation switch of each air cylinder, the solenoid valve of each air cylinder is actuated via the relay to send pressurized air from the air tank to each air cylinder.

[0005]

With the configuration of the present invention, the air that is sent under pressure from the compressor to the air tank that also functions as a frame after the engine is started is accumulated inside the air tank that also functions as a frame, and when the pressure gauge rises and the pressure reaches a constant pressure, The power of the circuit of the control box is automatically input by the operation of the switch, and when each operation switch of the tension cylinder, brake cylinder, throttle cylinder, and return cylinder is input, the electromagnetic valve operates and opens via the relay, and each cylinder is opened. The air pressure of the air tank is to be sent under pressure. When the tension cylinder is actuated, the belt becomes tight and power is transmitted to the drive wheels, and when the brake cylinder is actuated, the stop brake is released, and the drive wheels that sandwich the drive rail rotate. When the throttle cylinder is activated, the wire for opening and closing the throttle valve becomes tense and opens the valve to increase the engine speed.When the return cylinder is activated, the wire for opening and closing the throttle valve is loosened and the valve closes, causing the engine speed to increase. Becomes smaller.

[Effect of the Invention] According to the air tank which also functions as the frame of the monorail according to the present invention, it also functions as the frame of the monorail and the air tank of the compressed air which is pressurized by the compressor to operate the air cylinder. Therefore, the air that has been sent under pressure by the compressor into this becomes an air tank that accumulates in the internal space around the sealed frame. Since this is around the monorail, the parts provided in this air tank can be arranged by selecting the most suitable position around each air tank. By providing a connection port at an appropriate position around the frame and air tank, the electromagnetic valve 35 provided on the control box 5 is closest to the distance, and the distance from the air tank to the electromagnetic valve is closest to the pressure resistant pipe 20. Can be connected. Further, the lead wire 38 of the control circuit connected to the pressure switch 27 provided in the air tank can be shortest. For this reason, damage caused by being caught on the pressure-resistant pipe or the wiring is less likely to occur, and this effect enables economical use of the pressure-resistant pipe or the lead wire.

Since the conventional air tank was provided on the frame, in that case, the monorail air tank had to be provided separately from the frame, but the structure of the air tank that also serves as the frame of the present invention According to the above, it is not necessary to mount a separate air tank on the monorail as in the conventional case, and the fuel tank 10 is enlarged in an empty space above the frame of the monorail, and a battery mounting base is provided.
