Description

Technical Field

[0001] This disclosure relates to the field of rail transit technology, and in particular to a method, apparatus and related equipment for controlling the lubrication of locomotive wheel flanges. Background Technology

[0002] The working principle of the locomotive wheel-jet solenoid valve in related technologies is as follows: The Remote Input Output Module (RIOM) unit of the HXD2 (Harmony XD2 Electric Locomotive, where HXD is the abbreviation of the pinyin for Harmony Electric, representing the Harmony series electric locomotives of China Railway) locomotive control system shares a circuit breaker with the auxiliary contacts of the wheel-jet relay. When this circuit breaker is in the closed state, the RIOM unit drives the wheel-jet relay coil to be energized, the auxiliary contacts of the wheel-jet relay control the wheel-jet solenoid valve to be energized, and the actuator sprays lubricating grease onto both sides of the wheel flange. The wheel-jet solenoid valve is not associated with the locomotive control (forward direction), such as... Figure 1 As shown, the main structure of this circuit consists of only one wheel injection relay (KA-FLL) and one wheel injection solenoid valve (YV-FLL).

[0003] One method that can currently resolve this circuit structure defect is as follows: Figure 2 As shown, the auxiliary contacts of the energized relays at the I / II ends of the locomotive (for example, the HXD2 locomotive has a double-ended driver's cab structure, with I / II ends representing the two driver's cabs respectively) are connected in series to the wheel injection solenoid valve control circuit. Simultaneously, wheel injection solenoid valve 2 (YV-FLL2) is added to link the operation of the wheel injection solenoid valve with the locomotive control (forward movement); another method is as follows... Figure 3 As shown, one wheel injection relay (KA-FLL) and one wheel injection solenoid valve (YV-FLL2) are added. The wheel injection relays in the locomotive running direction are driven by the locomotive control unit. However, the difficulty of this solution is that not only are the circuit components modified, but the control logic of the locomotive also needs to be changed, and the cost of changing the control system logic is relatively large.

In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure.

[0026] Figure 4 A schematic diagram of a locomotive wheel flange lubrication control method in an embodiment of the present disclosure is shown. The method comprises the following steps:

[0027] S402, according to the control port of the starting key insertion, determine the driving direction and control logic of the target locomotive, the control logic is used to control the target locomotive to run according to the driving direction.

[0028] It should be noted that the starting key in the embodiments of the present disclosure can be an electrical key for starting the locomotive control system of the target locomotive, and after the starting key is inserted, the control circuit can be turned on to activate the operation permission of the cab of the target locomotive. Secondly, the control port in the embodiments of the present disclosure refers to an electrical key jack or interface installed in the cab. Each cab (front end and rear end) has one control port. After the starting key is inserted, the locomotive control system can identify which end is activated. In addition, the target locomotive in the embodiments of the present disclosure refers to the locomotive that needs to be controlled. For example, the target locomotive in the embodiments of the present disclosure can be a HXD2 type electric locomotive. In addition, the control logic in the embodiments of the present disclosure refers to a set of rules or programs in the locomotive control system. For example, the control logic can determine which operation buttons / switches are effective, how the direction controller responds, and the linkage mode of the braking and traction system.

[0029] S404, based on the driving direction of the target locomotive and the control logic, control the pre-stored lubricant to be sprayed onto the wheel rim of the target locomotive.

[0030] It should be noted that the pre-stored lubricant in the embodiments of the present disclosure refers to the lubricant (usually grease or solid lubricating material) stored on the locomotive for reducing the friction between the wheel rim and the track. The storage mode can be a tank, a box, or other forms of lubricating device. Secondly, the spraying of the lubricant onto the wheel rim of the target locomotive in the embodiments of the present disclosure is the process of spraying or applying the lubricant to the edge (wheel rim) of the locomotive wheel at a certain pressure or in a certain way, which aims to reduce wheel-rail wear, reduce noise, and improve running stability.

[0031] The locomotive wheel rim lubrication control method provided in the embodiments of the present disclosure first determines the driving direction of the target locomotive and the control logic for controlling the target locomotive to run in the driving direction according to the control port into which the starting key is inserted. Then, based on the driving direction of the target locomotive and the control logic, the pre-stored lubricant is controlled to be sprayed onto the wheel rim of the target locomotive. Compared with the related art in which the locomotive wheel spray electromagnetic valve is powered on to spray grease on both sides of the wheel rim regardless of the running direction of the locomotive, the embodiments of the present disclosure determine the driving direction of the target locomotive and the control logic through the control port into which the starting key is inserted, and spray the pre-stored lubricant onto the wheel rim of the target locomotive when the target locomotive runs in the driving direction. The direction of the wheel rim grease spraying is associated with the locomotive forward movement, which reduces the amount of lubricating grease used for the locomotive wheel rim and saves costs.

[0032] In some embodiments, the disclosure controls the pre-stored lubricant to be sprayed onto the wheel rim of the target locomotive based on the driving direction and control logic of the target locomotive, including: controlling the closing of the power-on relay auxiliary contact and the wheel spray relay auxiliary contact in the target locomotive based on the control logic of the target locomotive; after the power-on relay auxiliary contact and the wheel spray relay auxiliary contact in the target locomotive are both closed, controlling the opening of the wheel spray electromagnetic valve in the target locomotive to make the pre-stored lubricant sprayed onto the wheel rim of the target locomotive. Specifically, the closing of the power-on relay auxiliary contact in the disclosure indicates that the locomotive control system has been powered on and is running normally, preventing the lubrication function from being mistakenly started in a no-power state, and the closing of the wheel spray relay auxiliary contact indicates that the lubrication system is ready, avoiding forcibly spraying lubricant in the case that the target locomotive is not ready, and only when both contacts are closed, the wheel spray electromagnetic valve is triggered, forming a hardware level interlock to prevent a single signal from being mistakenly triggered. In addition, the spraying of the lubricant to the wheel rim in the disclosure can effectively reduce the friction and wear between the wheel and the rail, especially suitable for high wear conditions such as curves, low speed and large traction, and the control logic can determine whether lubrication is needed according to the driving direction, speed, curve and other information of the target locomotive, realize on-demand spraying, and reduce waste.

[0033] In some embodiments, the control port in the disclosure includes a first control port and a second control port, and the driving direction and control logic of the target locomotive are determined according to the control port into which the starting key is inserted, including: detecting whether the starting key is inserted into the first control port or the second control port; determining whether the current operating end is the first control end or the second control end according to the control port into which the starting key is inserted; and determining the driving direction and control logic of the target locomotive based on the determination result. Specifically, the locomotive control system in the disclosure does not need to manually select the current operating end, and can automatically identify the first control end or the second control end (generally, the control end of the locomotive can be the front or rear cab, and the disclosure does not specifically limit the first control end and the second control end) through the insertion position of the starting key, improving the operation convenience. It should be noted that if the first control end is set as the front cab and the second control end is set as the rear cab, the disclosure defaults that the target locomotive is driving forward when the key of the front cab (i.e. the first control end) is inserted, and defaults that the target locomotive is driving backward when the key of the rear cab (i.e. the second control end) is inserted. The determination of whether the current operating end is the first control end or the second control end can avoid misjudgment of the direction.

[0034] In some embodiments, the disclosure determines the driving direction and control logic of the target locomotive based on the determination result, including: if the current operating end is the first control end, the driving direction of the target locomotive is the first control end direction, and the control logic is to control the target locomotive to run in the first control end direction; if the current operating end is the second control end, the driving direction of the target locomotive is the second control end direction, and the control logic is to control the target locomotive to run in the second control end direction. Specifically, the disclosure automatically sets the driving direction of the target locomotive and loads the corresponding control logic by identifying the currently activated operating end (i.e., the control end where the key is inserted), thereby realizing intelligent, automatic and safe direction control.

[0035] In some embodiments, the wheel spray electromagnetic valve in the disclosure includes a first wheel spray electromagnetic valve and a second wheel spray electromagnetic valve. Based on the driving direction and control logic of the target locomotive, the pre-stored lubricant is controlled to be sprayed onto the rim of the target locomotive, including: if the driving direction of the target locomotive is the first control end direction, the first wheel spray electromagnetic valve in the target locomotive is controlled to be opened to make the pre-stored lubricant sprayed onto the rim of the target locomotive; if the driving direction of the target locomotive is the second control end direction, the second wheel spray electromagnetic valve in the target locomotive is controlled to be opened to make the pre-stored lubricant sprayed onto the rim of the target locomotive. Specifically, the disclosure selects the corresponding wheel spray electromagnetic valve according to the driving direction (forward / reverse) of the target locomotive, ensures that the lubricant is sprayed onto the rim of the currently stressed side, improves the lubrication effect, avoids spraying lubricant on the non-stressed side or invalid area, reduces lubricant waste and track pollution, and in the curve or turning working condition, the rim of the stressed side is more prone to wear, and precise lubrication can effectively alleviate the problem. The disclosure selectively opens the wheel spray electromagnetic valve at the corresponding position by identifying the driving direction of the locomotive, thereby realizing directional lubrication control, improving lubrication efficiency, reducing waste, and enhancing wheel-rail matching performance.

[0036] In some embodiments, the locomotive rim lubrication control method in the disclosure further includes: if the first control port and the second control port are simultaneously inserted with the starting key, the target locomotive cannot run normally. Specifically, if both ends of the starting key are inserted, it means that both driver's cabs try to control the target locomotive, which is prone to cause operation conflicts. The disclosure prevents dangerous situations by prohibiting operation, avoids safety hazards such as inconsistent directions and traction and braking instruction conflicts caused by misoperation or human error, thereby ensuring the safety and operation specification of the target locomotive.

[0037] In some embodiments, the current locomotive wheel spraying solenoid valve works regardless of the locomotive running direction, and the wheel spraying solenoid valve is powered on to spray the wheel flange on both sides. The embodiment of the present disclosure can control the direction of the wheel flange spraying to be associated with the locomotive forward direction, reduce the use of wheel flange lubricating grease, save costs, and control the wheel spraying solenoid valve to be powered on according to the actual application requirements of the locomotive, thereby prolonging the service life of the solenoid valve.

[0038] In some embodiments, the embodiment of the present disclosure adds a wheel spraying solenoid valve 2 (YV-FLL2) in the related art original circuit structure as shown in Figure 1 HXD2 locomotive first control end is inserted into the starting key, at this time the first control end is considered as the target locomotive forward direction, the locomotive control system controls the power-on relay (KA-PS1) of the first control end (note: after the first control end and the second control end are inserted into the starting key, the display screen of the locomotive control system will prompt "conflict of occupied ends" and the locomotive cannot continue to be controlled, so only one power-on relay is powered on (the power-on relay on the first control end or the second control end, it should be noted that the power-on relay (KA-PS2) of the second control end has the same control principle as the power-on relay (KA-PS1) of the first control end). When the locomotive control system controls the power-on relay (KA-PS1) of the first control end and the wheel spraying relay coil (KA-FLL) is powered on, the auxiliary contact of the power-on relay (KA-PS1) in the circuit is closed at the same time, the auxiliary contact of the wheel spraying relay (KA-FLL) is closed at this time, the wheel spraying solenoid valve 1 (YV-FLL1) works, at this time the wheel flange of the first control end forward direction is sprayed, thereby realizing the association of the wheel spraying solenoid valve with the locomotive control (forward) direction. Similarly, the second control end has the same circuit structure as the original control, which can control the wheel spraying solenoid valve to be powered on according to the actual application requirements of the locomotive, thereby reducing the use of wheel flange lubricating grease, saving corresponding costs, and prolonging the service life of the solenoid valve.

[0039] In some embodiments, the embodiment of the present disclosure provides an improved circuit structure for realizing the association of the wheel spraying solenoid valve with the locomotive control (forward) direction, which has low modification cost and is easy to operate, overcomes the difficulty of software modification of some HXD2 locomotives, thereby realizing the association of the wheel spraying solenoid valve with the locomotive running direction, prolonging the service life of the solenoid valve, and saving material costs.
