Description

  The present invention relates to an injection device that injects an injection material between a wheel and a rail of a vehicle.

  Railway vehicles transmit driving force and braking force by rolling friction acting between the rail and the wheel, and the maximum traction force, gradient climbing speed, brake deceleration depending on the adhesion state between the rail and wheel. And the maximum driving speed is affected. For this reason, in the railway vehicle, when the adhesive force between the rail and the wheel is lowered, idling or sliding that is a macroscopic slip occurs between them. Here, idling is a macroscopic phenomenon that occurs between the wheel tread surface and the rail top surface when the driving force transmitted to the wheel during power running (driving) is greater than the adhesive force acting between the wheel and the rail. Such slipping is likely to occur when the rails are in a wet state contaminated by snow, rain or fallen leaves. Sliding is a macroscopic slip that occurs between the wheel tread surface and the rail top surface when the rotational speed of the wheel is lower than the traveling speed of the vehicle during braking and the wheel slides on the rail.

  In railway vehicles, in order to prevent such slipping and skiing, the adhesive performance is improved by injecting an adhesive material between the rail and the wheel with a jetting device at the time of low adhesion. A conventional injection device includes a thickened adhesive material tank that contains a thickened adhesive material, an air tank that contains compressed air, a nozzle that sprays compressed air and a thickened adhesive material onto the top surface of the rail, and a thickened adhesive material from the nozzle. A switching valve for supplying and stopping the supply of compressed air from the air tank to the pressure-sensitive adhesive material tank is provided for injection (see, for example, Patent Document 1). When such a conventional injection device detects slipping or sliding of a wheel, the switching valve is opened to supply compressed air from the air tank to the increased adhesive material tank. In the meantime, the adhesive is sprayed.

Japanese Unexamined Patent Publication No. 4-310464

  In the conventional injection device, the compressed air in the air tank is supplied to the increased adhesion material tank by the switching operation of the switching valve, and the increased adhesion material is injected from the nozzle by the compressed air, and the injection amount of the compressed air is substantially constant. Therefore, the injection amount of the increased adhesive material is also substantially constant. For this reason, in the conventional injection device, although a small degree of idling or sliding is small, it is sufficient to inject a small amount of the adhesive material, but a large amount of the adhesive material is injected, and the adhesive material is consumed wastefully. There is a problem. On the other hand, with the conventional injection device, there is a problem that it is not possible to prevent idling or sliding by injecting a small amount of increased adhesive material even though the degree of idling or sliding is large and it is necessary to inject a large amount of increased adhesive material There is a point.

  In addition, when using an electric flow control valve, the disc-shaped valve body of the flow control valve is rotated by a motor, the opening degree of the flow control valve is adjusted by the control unit, It becomes possible to variably control the injection amount. However, when an electric flow control valve is used, the flow control valve receives vibrations that occur when the vehicle is running. Therefore, the flow control valve is operated quickly and the opening of the flow control valve is adjusted with high accuracy. It is difficult to do this, and there is a problem that dispersion of the amount of the increased adhesive material occurs.

It is a variable throttle valve that can adjust the opening (throttle amount). The variable throttles T _{0 to} T ₂ are adjusted and set in advance to a predetermined throttle opening while the vehicle 2 is stopped. For example, in the variable throttle T ₀ shown in FIG. 5, the throttle opening is set to the minimum value “1”, and the variable throttle T ₁ is a compressed air in which the flow rate of the compressed air flowing through the flow path P ₁ flows through the flow path P _0. the flow rate of throttle opening degree to be twice the flow rate is set to "2" (twice the throttle opening of the variable throttle T _0), the variable throttle T ₂ are of the compressed air flowing through the flow channel P ₂ Is set to “3” (three times the throttle opening of the variable throttle T ₀ ) so that it becomes three times the flow rate of the compressed air flowing through the flow path P ₀ .

The fixed throttles T _L and T _R are ejected from the ejection ports 12L and 12R when the distance from the ejected matter accommodation unit 9L to the ejection port 12L is different from the distance from the ejection matter accommodation unit 9R to the ejection port 12R. The injection amount of the increased adhesive material C is made constant.

The ejected matter accommodating portions 9L and 9R are portions that accommodate the increased adhesion material C.

The variable throttles 10L and 10R are adjusted and set in advance to a predetermined throttle opening, and adjust the mixing ratio between the compressed air discharged from the ejected matter storage portions 9L and 9R and the thickened adhesive C.

  The flow paths 11L and 11R shown in FIGS. 4 and 5 are pipes through which the compressed air and the increased adhesive material C flow. The flow passages 11L and 11R are provided with the pressure-sensitive adhesive C in order to supply the pressure-sensitive adhesive C between the rails 1a and 1b and the wheels 4a and 4b toward the injection ports 12L and 12R. Is sent out. The flow paths 11L and 11R have upstream sides connected to the ejected matter storage portions 9L and 9R, and downstream sides connected to the injection ports 12L and 12R.

  The adhesion state detection unit 13 is a device that detects an adhesion state between the wheels 4a and 4b and the rails 1a and 1b. The adhesion state detection unit 13 detects, for example, idling of the wheels 4a and 4b in which the wheels 4a and 4b slide on the rails 1a and 1b during power running (drive), and the wheels 4a and 4b move on the rails 1a and 1b during braking. The sliding of the sliding wheels 4a and 4b is detected. After the wheels 4a and 4b are idling or sliding, the adhesion state detection unit 13 increases the adhesion force between the wheels 4a and 4b and the rails 1a and 1b or decreases the driving force or the braking force, so that the wheel 4a , 4b is detected as re-adhesion of the wheels 4a, 4b at which the rotational speed of the vehicle 4 returns to the same speed as the traveling speed of the vehicle 2. For example, in order to prevent damage to the wheels 4a and 4b and the rails 1a and 1b, the adhesion state detection unit 13 detects a macroscopic slip between the wheels 4a and 4b and the rails 1a and 1b, and the wheels 4a and 4b.

When the adhesion state detection unit 13 detects a macroscopic slip such as idling and / or sliding of the wheels 4a and 4b, it outputs an idling / sliding detection signal (slip detection signal) to the control device 17, and the wheels 4a and 4b. When re-adhesion is detected, a re-adhesion detection signal is output to the control device 17.

In order to select the large quantity injection mode to inject, it is a slide type or push button type switch manually operated by the crew of the vehicle 2. The injection amount selection unit 16 outputs an injection mode selection signal to the control device 17 according to the selected injection mode.

The control device 17 is a device that controls various operations of the injection device 5. The control device 17 opens and closes the opening / closing valves S _{0 to} S ₂ based on the detection results of the adhesion state detection unit 13, the speed detection unit 14 and the emergency brake operation detection unit 15 and the selection result of the injection amount selection unit 16. And the injection operation of the gas injection part 6 is controlled. The control device 17 controls the operation of the gas injection unit 6 and the on-off valves S _{0 to} S ₂ so as to inject the increased adhesion material C on the basis of the idling / sliding detection signal output from the adhesion state detection unit 13. based on readhesion detection signal state detector 13 outputs, controls the operation of the gas injection unit 6 and the on-off valve S ₀ to S ₂ to stop injection of increasing adhesive C. The control device 17, for example, on the basis of the slip / skid detection signal output from the pressure-sensitive adhesive state detector 13, the compressed air on-off valve S ₀ to S ₂ by opening and closing with a gas injection unit 6 Ru is injection operation flow Adjust. The control device 17 outputs an injection operation start signal to the gas injection unit 6 when the gas injection unit 6 starts the injection operation, and outputs an injection operation end signal to the gas injection unit 6 when the gas injection unit 6 ends the injection operation. Output. The controller 17 is operated to open and close operation of the open-close valve S ₀ to S ₂ and outputs a closing operation signal (electrical signal) to the opening and closing valve S ₀ to S _2.

When the traveling speed of the vehicle 2 exceeds a predetermined speed and the emergency brake operation detecting unit 15 detects the operation of the emergency brake device, the control device 17 causes the gas injection unit 6 and the gas injection unit 6 to inject the increased adhesive material C. The on-off valves S _{0 to} S ₂ are controlled. For example, when the emergency braking device is activated when the traveling speed of the vehicle 2 exceeds 130 km / h, the control device 17 travels from when the emergency braking device receives an operation command until the vehicle 2 stops. In order to ensure a sufficient emergency braking distance, the gas injection unit 6 and the on-off valves S _{0 to} S ₂ are controlled to inject the increased adhesive material C.

The control device 17 sets the total throttle opening values of the variable throttles T _{0 to} T ₂ shown in FIG. 5 to “1” to “3” according to the injection mode selected by the injection amount selection unit 16. Then, the opening / closing operation patterns of the on-off valves S _{0 to} S ₂ are switched to vary the injection amount of the increased adhesive material C in three stages. As shown in FIG. 6, the control device 17 forms a table (database) the opening / closing operation patterns of the opening / closing valves S _{0 to} S ₂ for each injection mode selected by the injection amount selection unit 16, and sets the injection mode setting information. stores as, on the basis of the injection mode selection signal output by the injection amount selector 16, setting the opening and closing operation pattern switching valve S ₀ to S ₂ standard injection mode, to one of small amounts injection mode or multimeric injection mode To do.

When the small amount injection mode is selected by the crew member manually operating the injection amount selection unit 16 shown in FIGS. 4 and 5, the injection amount selection unit 16 outputs a small amount injection mode selection signal to the control device 17. When the control device 17 determines that the small injection mode selection signal is input, the process proceeds to S110, and when the control device 17 determines that the small injection mode selection signal is not input, the process proceeds to S160.

  In S120, the control device 17 determines whether or not the adhesion state detection unit 13 has detected idling or sliding of the wheels 4a and 4b. When the adhesion state detection unit 13 detects idling or sliding of the wheels 4 a and 4 b, the adhesion state detection unit 13 outputs an idling / sliding detection signal to the control device 17. When the control device 17 determines that the idling / sliding detection signal is input, the process proceeds to S130, and when the control device 17 determines that the idling / sliding detection signal is not input, the series of operations ends.

In S <b> 130, the control device 17 instructs the gas injection unit 6 and the injection amount variable unit 8 to start a small amount injection of the increased adhesive material C. When the adhesion state detection unit 13 outputs an idling / sliding detection signal to the control device 17, the control device 17 instructs the gas injection unit 6 to start the gas injection operation, and the opening / closing valves S _{0 to} S ₂ start the opening / closing operation. The control device 17 gives a command. When the control device 17 outputs a gas injection start signal to the gas injection unit 6 and the control device 17 outputs an opening / closing operation signal to the on-off valves S _{0 to} S ₂ , compressed air is supplied from the air tank of the gas injection unit 6 to the flow path 7. At the same time, the on-off valve S ₀ opens the flow path P ₀ , and the on-off valves S ₁ , S ₂ close the flow paths P ₁ , P ₂ . Therefore, the compressed air flowing into the flow path 7 from the air tank of the gas injection unit 6 shown in FIG. 5 flows into the flow path P ₀ , passes through the variable throttle T ₀ , and flows into the flow paths P _L and P _R. Passes through the fixed apertures T _L and T _R. As a result, the increased pressure-sensitive adhesive C is injected from the projecting matter accommodating portions 9L and 9R into the flow paths 11L and 11R, and the increased pressure-sensitive adhesive C is injected in a small amount from the injection ports 12L and 12R together with the compressed air.

  As shown in FIG. 5, when the injection device 5 starts to inject the increased adhesive material C between the wheels 4a and 4b of the vehicle 2 and the rails 1a and 1b, the increased adhesive material is applied to the wheel tread 4c immediately before the contact point S. C collides and the pressure-sensitive adhesive C is stepped on between the rails 1a, 1b and the wheels 4a, 4b. As a result, the frictional resistance between the top surfaces 1c of the rails 1a and 1b and the wheel treads 4c of the wheels 4a and 4b shown in FIG. 3 is increased and is generated between the rails 1a and 1b and the wheels 4a and 4b. A slipping or sliding that is a macroscopic slip is prevented.

In S140, the control device 17 determines whether or not the adhesion state detection unit 13 has detected re-adhesion of the wheels 4a and 4b. When the adhesion state detection unit 13 detects re-adhesion of the wheels 4 a and 4 b, the adhesion state detection unit 13 outputs a re-adhesion detection signal to the control device 17. When the control device 17 and readhesion detection signal is input is determined proceeds to S150, when the control unit 17 and readhesion detection signal has not been input is judged proceeds to S170, the opening and closing operation pattern switching valve S ₀ to S ₂ Is changed from the small injection mode to the normal injection mode by the control device 17.

In S180, the control device 17 determines whether or not the adhesion state detection unit 13 has detected idling or sliding of the wheels 4a and 4b. When the control device 17 determines that the idling / sliding detection signal is input from the adhesion state detection unit 13, the process proceeds to S190. When the control device 17 determines that the idling / sliding detection signal is not input, the process returns to S110, and the on-off valve S ₀ to S ₂ of the switching operation pattern control device in a small amount injection mode from the normal injection mode 17 is changed to set.

In S190, the control device 17 commands the gas injection unit 6 and the injection amount variable unit 8 to start normal injection of the increased adhesive material C. When the control device 17 outputs a gas injection start signal to the gas injection unit 6 and the control device 17 outputs an opening / closing operation signal to the on-off valves S _{0 to} S ₂ , compressed air is supplied from the air tank of the gas injection unit 6 to the flow path 7. As it flows in, on-off valve S ₁ opens channel P ₁ and on-off valves S ₀ , S ₂ close channels P ₀ , P ₂ . Therefore, the compressed air flowing into the flow path 7 from the air tank of the gas injection unit 6 shown in FIG. 5 flows into the flow path P ₁ , passes through the variable throttle T ₁ , and flows into the flow paths P _L and P _R. Passes through the fixed apertures T _L and T _R. As a result, the double-adhesive material C that is twice as large as that in the small-quantity injection is injected into the flow passages 11L and 11R from the ejected matter storage portions 9L and 9R, and the increased adhesive material C is injected from the injection ports 12L and 12R together with the compressed air.

In S200, the control device 17 determines whether or not the adhesion state detection unit 13 has detected re-adhesion of the wheels 4a and 4b. When readhesion detection signal from the pressure-sensitive adhesive state detector 13 the control device 17 and is input is determined, the process proceeds to S210, when the control unit 17 and readhesion detection signal has not been input is judged proceeds to S230, the opening and closing valves S ₀ ~ The control device 17 switches and sets the opening / closing operation pattern of S ₂ from the normal injection mode to the large quantity injection mode.

  In S220, the control device 17 determines whether or not the injection amount selection unit 16 has selected the large injection mode. When the crew member manually operates the injection amount selection unit 16 shown in FIGS. 4 and 5 and the large injection mode is selected, the injection amount selection unit 16 outputs a large injection mode selection signal to the control device 17. When the control device 17 determines that the large injection mode selection signal has been input, the process proceeds to S230, and when the control device 17 determines that the large injection mode selection signal has not been input, the series of operations ends.

In S230, the control unit 17 sets a large amount injection mode opening and closing pattern of the on-off valve S ₀ to S _2. When the injection amount selection unit 16 outputs a large injection mode selection signal to the control device 17, the opening / closing operation pattern of the on-off valves S _{0 to} S ₂ is set to the large injection mode as shown in FIG.

In S240, the control device 17 determines whether or not the adhesion state detection unit 13 has detected idling or sliding of the wheels 4a and 4b. When the control device 17 determines that the idling / sliding detection signal is input from the adhesion state detection unit 13, the process proceeds to S250. When the control device 17 determines that the idling / sliding detection signal is not input, the process returns to S170, and the on-off valve S ₀ normal injection mode to the control device 17 the opening and closing operation pattern from the large amount injection mode to S ₂ are changed to set.

In S250, the control device 17 instructs the gas injection unit 6 and the injection amount variable unit 8 to start a large amount injection of the increased adhesive material C. When the control device 17 outputs a gas injection start signal to the gas injection unit 6 and the control device 17 outputs an opening / closing operation signal to the on-off valves S _{0 to} S ₂ , compressed air is supplied from the air tank of the gas injection unit 6 to the flow path 7. As it flows in, the on-off valve S ₂ opens the flow path P ₂ , and the on-off valves S ₀ , S ₁ close the flow paths P ₀ , P ₁ . For this reason, the compressed air flowing into the flow path 7 from the air tank of the gas injection unit 6 shown in FIG. 5 flows into the flow path P ₂ , passes through the variable throttle T ₂ , and flows into the flow paths P _L and P _R. Passes through the fixed apertures T _L and T _R. As a result, the increased adhesive material C that is 1.5 times the normal injection (3 times the small amount injection) is injected into the flow passages 11L and 11R from the ejected matter storage portions 9L and 9R, and the increased adhesive C is compressed air. At the same time, the fuel is injected from the injection ports 12L and 12R.

For example, the flow paths P ₀ and P ₂ are opened, the flow path P ₁ is closed, the total value of the throttle opening is set to “4”, the flow paths P ₁ and P ₂ are opened, and the flow path P ₃ is closed. Then, the total value of the throttle opening is set to “5”, the flow paths P _{0 to} P ₂ are opened, the total value of the throttle opening is set to “6”, and the injection mode is switched to six stages. it can. In this embodiment, the case where the total value of the throttle openings of the variable throttles T _{0 to} T ₂ is set to “1” to “3” has been described as an example, but the variable throttles T _{0 to} T ₂ The total value of the throttle opening is not limited to these values. For example, by setting all the throttle openings of the variable throttles T _{0 to} T ₂ to “1” and changing the opening / closing operation pattern of the on-off valves S _{0 to} S ₂ , the total value of the throttle openings is set to “1” to “ 3 "can also be adjusted. Similarly, the variable throttle T ₀ through T ₂ of the throttle opening degree a _n a 2 ⁿ set (n = 0, 1, 2, ...), it is also possible to switch the injection mode to the n stages. Furthermore, in this embodiment, the case where the injection device 5 is installed on the vehicle 2 side has been described as an example. However, the injection device 5 is installed on the ground side, and between the top surface 1c and the wheel tread surface 4c from the ground side. It is also possible to spray the thickened adhesive material C.
