Description

Technical Field

[0001] The present invention belongs to the field of rail transportation, in particular to an electrified rail transportation power supply pantograph network system, and specifically relates to a vehicle-mounted intelligent pantograph carbon slide lubrication device. Background Art

[0002] With the rapid development of the transportation sector, my country's railway transportation capacity has greatly improved, and technological equipment has also experienced rapid advancement. In electrified railway transportation, the pantograph is the device that draws power from the grid during train operation, and the pantograph carbon slide is a key component for current collection on the vehicle. The pantograph carbon slide contacts the contact wire through mechanical sliding. On the one hand, the pantograph carbon slide slides longitudinally with the contact wire in the direction of the train's movement. On the other hand, due to the contact wire's pull-out arrangement, it moves laterally on the slide slide. Friction between the pantograph and the contact wire inevitably causes wear. Different positions on the carbon slide slide have different wear rates and different relative sliding distances from the contact wire, resulting in uneven wear on the carbon slide slide. Coupled with the complexity of the train operating environment, excessive or uneven wear can shorten the carbon slide slide's service life and even pose serious and difficult-to-calculate safety risks. Frequent replacement of the carbon slide slide not only increases operating consumable costs but also increases the workload of maintenance personnel.

[0003] Patent application CN94117279.1 discloses a solid lubricant strip for electric locomotive pantographs, consisting of an aluminum alloy frame and lubricating material. The frame includes a lubricating surface and a single wing. The lubricating surface is provided with holes of arbitrary shapes, each with an area of ​​1-10 mm², and the total area of ​​the holes accounts for at least 60% of the lubricating surface. The wing also has fixed elongated holes. The lubricating material is cast onto the lubricating surface. The process involves cutting an aluminum alloy sheet into an elongated shape and pressing it into shape, with the lubricating surface and the wing each occupying half. The ends of the wing are cut at 45-degree angles, giving the wing a parallelogram shape. The wing is then placed in a mold and the lubricating material is cast onto the lubricating surface. However, due to the structural limitations of the lubricating material and the lack of a compensation system, this technology cannot achieve continuous lubrication during use. Furthermore, it cannot achieve lubrication in required sections of road, such as those with curves. Furthermore, it cannot use new conductive lubricants, greases, or lubricating powders.

[0004] The existing technology reduces wear by selecting conductive materials with low friction coefficient from the carbon slide material or controlling the contact surface smoothness of the carbon slide and the contact wire. However, it is restricted by the existing limited conductive low friction coefficient material technology, and it is difficult to simply maintain the surface quality of the carbon slide and the contact wire due to the installation geometric accuracy of the pantograph system, the relative position of the pantograph carbon slide installed on the vehicle and the contact wire installed on the line during the operation of the complex track and vehicle system, the impact and vibration during the operation of the pantograph, etc. Therefore, the carbon slide and the contact wire still have the problem of rapid wear, especially abnormal wear. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a vehicle-mounted intelligent pantograph carbon slide lubrication device, which can reduce or slow down the wear of the pantograph carbon slide, extend the service life of the pantograph carbon slide, and at the same time accurately lubricate and save lubricating materials.

[0006] The purpose of the present invention can be achieved through the following technical solutions: a vehicle-mounted intelligent pantograph carbon slide lubrication device, which is used for lubrication between the pantograph carbon slide and the contact network line of an electric train. The lubrication device includes an intelligent control system, a network interface, a pantograph network status detection system, a lubrication system and a vehicle-mounted mounting base. The lubrication system includes a lubrication main box and a lubricant output end and a coating nozzle. The lubrication main box includes a lubricant storage cylinder, lubricant, a filter, a lubricant pump, a control valve, a lubrication controller, and a lubricant pipeline. The lubricant output end is connected by a distributor and a coating nozzle. The lubrication system is installed on the roof panel of the train through the vehicle-mounted mounting base, and the coating nozzle is fixed to the side of the pantograph carbon slide.

[0007] Furthermore, the intelligent control system obtains information from a pantograph-catenary status detection system installed on the pantograph head frame and gives instructions to the lubrication system through a contact force and friction resistance algorithm.

[0008] Furthermore, the pantograph-catenary status detection system includes pressure sensors installed between the two ends of the pantograph balance support frame and the carbon slide, and a vibration sensor installed below the carbon slide.

[0009] Furthermore, the network interface is connected to the intelligent control system, the pantograph-catenary status detection system, the lubrication system and the vehicle operation and line station system through the existing train communication network.

[0010] Furthermore, the lubricant of the lubrication system is a conductor with a low friction coefficient, and the friction coefficient formed by the lubricant between the pantograph carbon slide plate and the contact network line is no more than 0.35.

[0011] Furthermore, a lubrication main box, consisting of a lubricant storage tank, lubricant, filter, lubricant pump, control valve, lubrication controller, and lubricant piping, is mounted on a vehicle mounting base via insulating fasteners. The lubricant storage tank contains lubricant and is sequentially connected to the filter, lubricant pump, control valve, and distributor via lubricant piping. The lubrication controller is individually connected to the filter, lubricant pump, control valve, and intelligent control system.

[0012] Furthermore, the lubricant pump is driven by a motor and has a built-in control valve; the lubricant storage cylinder has a built-in lubricant capacity indicator sensor.

[0013] Furthermore, the coating nozzle comprises a small hole for free liquid flow or can be a grease-like lubricating medium extrusion tube head or a powder nozzle for solid powder lubricating medium.

[0014] Furthermore, the lubricant lubricating medium is conductive lubricating liquid, lubricating grease or lubricating powder.

[0015] Furthermore, the control terminal of the intelligent control system can be a mobile phone or a computer, and the lubrication system is controlled and the operating status is detected through control software.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention sets a lubrication system on the roof panel, and the lubricant in the system is sprayed onto the carbon slide through a coating nozzle. The coating nozzle is installed on the carbon slide, and the number of installation nozzles can be symmetrically set as needed to balance the additional weight of the carbon slide and avoid vibration impact. At the same time, a pressure sensor and a vibration sensor are installed on the carbon slide to measure and set the contact pressure and vibration level corresponding to the friction resistance range. When the pressure or vibration exceeds the set value, the information obtained is given to the lubrication system through the contact force and friction resistance algorithm through the pantograph state detection system, and the lubricant is automatically adjusted and sprayed. In this way, the pantograph carbon slide and the contact network line are lubricated according to the actual line position and lubrication requirements during the train operation, thereby reducing the friction resistance and impact force of the pantograph network, thereby extending the service life of the pantograph carbon slide and the contact network line.

[0018] 2. The intelligent control system of the present invention realizes intelligent control of the lubrication device to coat the pantograph carbon slide at the specified line position and coating amount, thereby achieving precise lubrication, saving lubricant materials, improving the economic benefits of train operation, and ensuring safe and reliable operation incentives for vehicles.

[0019] 3. The present invention has a simple structure and is easy to implement. It can be directly applied to the existing vehicle pantograph system or directly introduced into the design of a new vehicle pantograph system. BRIEF DESCRIPTION OF THE DRAWINGS

The lubrication system 5 includes a lubrication main box 51, a lubricant output terminal 52, and a coating nozzle 53. The lubrication main box 51 is connected to the lubricant output terminal 52, and the lubricant output terminal 52 is connected to the coating nozzle 53 by a distributor 521. The coating nozzle 53 is fixed to the side of the pantograph carbon slide 11.

[0025] The lubrication main box 51 includes a lubricant storage cylinder 511, a lubricant 512, a filter 513, a lubricant pump 514, a control valve 515, a lubrication controller 516, and a lubricant pipeline 517. The lubricant storage cylinder 511 is filled with lubricant 512 and is connected in sequence to the filter 513, the lubricant pump 514, the control valve 515 and the distributor 521 through the lubricant pipeline 517. The lubrication controller 516 is respectively connected to the filter 513, the lubricant pump 514, the control valve 515 and the intelligent control system 2. The lubrication system 5 is installed on the train roof panel 7 through the vehicle-mounted mounting seat 6. Specifically, the lubrication main box 51 consisting of the lubricant storage cylinder 511, the lubricant 512, the filter 513, the lubricant pump 514, the control valve 515, the lubrication controller 516, and the lubricant pipeline 517 is installed on the vehicle-mounted mounting seat 6 through the insulating hardware 61.

In this embodiment, the lubricant 512 is a conductive lubricating fluid, and the coating nozzle 53 includes a small-hole nozzle for free-flowing liquid.

[0031] The friction resistance algorithm uses the following formulas (1) and (2) to obtain the friction resistance and friction coefficient from the pressure and acceleration obtained by the test system.

[0032] Frictional resistance = friction coefficient x contact force (1)

[0033] Friction resistance = equivalent mass of test point x acceleration of test point (2)
