Definitions
- the purpose of this patent application is to provide a device that allows the different brake tests of all trains to be carried out with a single person or agent.
- the driver must sit in the locomotive cabin and pay attention to the indications of the tail agent, operating the braking mechanisms or loosening the train brake and visually check the pressure drop of the automatic brake line pressure gauge when the Queuing agent opens the isolation tap of the last train vehicle.
- the tail agent checks the tightening and loosening of the shoes against the tires on each of the axles of the train, indicating the head agent to brake or loosen the brake of the train, as many times as it is. If necessary, you must also open the isolation tap of the last car to check the arrival of pressure to it and finally check the position of the regime and power changers, as well as that all the hand brakes are loosened.
- the petitioner of this Patent has devised an alternative system, supported by technology that allows checks and handling of the elements performed by the head agent, can be performed by the tail agent without forgetting his own, that is, he has devised a device that allows the brake tests of trains by a single agent.
- Said device is constituted by a radio control system consisting basically of two complete equipment, each consisting of a transmitter and a receiver.
- a fixed character device, transmitter and receiver installed in the locomotive and another portable and small in size to be transported by the agent who performs the test in the hand while traveling the train checking the brake.
- the portable equipment equipped with two braking and loosening buttons operated by the agent performing the test, governs a receiver located in the locomotive's fixed equipment that by appropriate means causes it to brake or loosen the automatic train brake depending on which button has been pressed. When no pushbutton is set, the braking will remain stabilized, neither will it be braked or loosened.
- an emitter in the fixed equipment connected to the automatic brake line of the locomotive, constantly sends, while connected, the value of the pressure in the said pipeline to the receiver of the portable equipment that presents this data in a display, allowing the agent performing the test to see at all times the value of the brake that has been applied.
- the portable equipment is installed inside a housing locked by means of a key in the locomotive. To proceed with its extraction and activate its operation, it is necessary to unlock it by turning the key. When making this turn, by means of electrical contacts available to the lock, three different types of circuits are established in the locomotive.
- a first circuit disables the locomotive control elements, leaving it unusable to stop circulating until the portable equipment is returned to its housing and the key is turned back to its locked position (a conventional safety mechanism prevents the key can never turn if the equipment is not in place) in anticipation that someone can access the locomotive while the agent is testing the brake.
- a second circuit is established to enable the automatic brake panel to be governed, or any other system that the locomotive can use to control the train brake, with the radio control element. In nailed position there is no possibility that other foreign radio control equipment can act on our brake. This circuit is established double, with two independent branches, to avoid that a hypothetical breakdown of an element of the circuit can result in the loosening of the train brake.
- the third circuit that is established by turning the interlocking key to its unlocked position allows the power supply of the locomotive's fixed radio control equipment that remains disconnected in its interlocking position, unable to receive any type of signal.
- the device's radio signal modulation system is encoded, making it virtually impossible for a different transmitter to usurp the government of the receiver. Each receiver only obeys its transmitter. On the other hand, when the receiver clearly stops receiving the signal from its transmitter for any reason (deterioration, battery depletion, interference, etc.), it goes on to perform a scheduled operation causing emergency braking, preventing the test from brake can be falsified. With this device, a single agent can perform queue agent and head agent operations.
- this single agent can perform all brake test operations by itself, saving time in waiting.
- Figure 1 Shows a schematic diagram of the brake test device with a single agent in operation or unlocked position.
- Figure 2. Shows a schematic diagram of the brake test device with a single agent in its locked position.
- a preferred but not limiting embodiment of the invention can be observed therein, which consists of a device formed by a portable radio control equipment -1-, of Small dimensions for easy handling, consisting of a transmitter -1a- and a receiver -1b- and a second fixed radio control equipment -2- that is installed in the locomotive, in turn composed of a transmitter -2a- and a -2b- receiver.
- a portable radio control equipment -1- of Small dimensions for easy handling, consisting of a transmitter -1a- and a receiver -1b- and a second fixed radio control equipment -2- that is installed in the locomotive, in turn composed of a transmitter -2a- and a -2b- receiver.
- From the transmitter -1a- of the portable equipment -1- by pressing the push buttons - 4- of which it is provided, it is sent over the receiver -2b- of the fixed equipment -2- which in turn is connected to the automatic train brake (no represented) to make the locomotive brake or loosen the automatic train brake.
- the emitter -2a- of the fixed equipment -2- which is connected to the automatic brake line of the locomotive (not shown), constantly sending the value of the existing pressure in it to the receiver -1 b- of the equipment portable, which presents this data in a display -3- of which it is provided (figure 1).
- the portable equipment -1- is installed inside a housing -5- locked by means of a key -6- in the locomotive. To be able to remove and operate the portable equipment -1-, it is necessary to unlock it by turning the key -6- (which cannot be returned to its position if the portable equipment -1 is not in its housing -5-) , establishing said rotation by means of electrical contacts, three different types of circuits in the locomotive.
- a circuit -7- disables the control elements of the locomotive being rendered useless to circulate in anticipation that someone can access them.
- a second circuit -8- allows the receiver -2b- of the fixed-radio control equipment -2- to control the automatic brake panel (or any other method that the locomotive can arrange for govern the train brake) depending on the orders received from the transmitter -1a- of the portable equipment -1-. This circuit is established double, with two independent branches, to avoid that a hypothetical breakdown of an element of the circuit can result in the loosening of the train brake.
- a third circuit -9- allows the fixed equipment -2 to be electrically supplied, which until then was disconnected and cannot receive any type of signal (figure 2).
- the device's receivers guarantee security by means of a PCM-type coding system that allows them to be programmed to carry out a specific order when the signal from their transmitter is not received clearly for any reason such as lack of coverage, exhaustion of battery, interference from another signal, etc., the receiver -2b- of the fixed equipment -2- goes to the braking position ensuring that only our transmitter can cause the locomotive to loosen the brake, allowing no error or interference.
