Description

TECHNICAL FIELD

[0001] The utility model relates to railway turnout system structural parts, especially a device that lubricates automatically for the slide bed platform of turnout slide bed plate. BACKGROUND

[0002] The turnout slide bed plate mainly bears the point rail and the basic rail and is an important component of the railway turnout. The turnout slide bed plate structure is mainly composed of an iron pad, a slide bed platform and a rubber pad, the iron pad is above the rubber pad, and the slide bed platform is above the iron pad. The friction between the slide bed platform and the rail is the biggest factor affecting the point rail pulling force and the insufficient displacement. The traditional slide bed plate material has a large friction coefficient (0.25 or more), and with the increase of service time, the rust on the rail bottom surface will cause scratches on the surface of the slide bed platform after friction, and the interlayer friction increases, so regular manual oiling is required. However, after the slide bed platform surface is oiled, fine sand carried by train wind will stick to the surface, causing deeper scratches on the slide bed platform after the point rail is pulled, further increasing the friction coefficient; and the oil stains will also corrode the rubber pad, reducing its performance and fatigue life. SUMMARY

[0003] The utility model aims at providing a self-induction slide bed platform lubricating device to replace manual oiling with automatic lubrication to improve the above problems.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A self-induction slide bed platform lubricating device, comprising an iron pad, a slide bed platform and a rubber pad, the iron pad is above the rubber pad, and the slide bed platform is above the iron pad, characterized in that: a plurality of spraying devices are installed on the iron pad, and the plurality of spraying devices are arranged on the left and right sides of the slide bed platform.

[0006] The utility model has the advantages of:

[0007] 1. The utility model replaces manual oiling of the slide bed platform with spraying of high-lubricating and quick-drying lubricant on the iron pad, avoiding the sticking of fine sand carried by train wind to the surface of the slide bed platform after oiling, causing deeper scratches on the slide bed platform after the point rail is pulled, and further increasing the friction coefficient of the slide bed platform. The sprayed lubricant forms an oil film on the slide bed platform, playing a good lubricating role and effectively reducing the friction coefficient between the bottom of the point rail and the slide bed platform, thereby reducing the point rail pulling force and the point rail insufficient displacement, and being more conducive to the maintenance of the geometric line type and shape position of the turnout rail.

[0008] 2. This utility model protects the slide table by spraying a highly lubricating and quick-drying lubricant through a spraying device, avoiding the need for applying lubricating oil and preventing oil stains, thus preventing corrosion of the rubber pad. This improves the performance and fatigue life of the rubber pad and reduces the maintenance workload of the railway turnout system.

[0009] Other features and advantages of this invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing embodiments of the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the written description, claims, and drawings.

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0018] It should be noted that: similar labels and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0019] As Figures 1-4As shown, this embodiment provides a self-sensing slide table lubrication device. The device includes an iron pad 1, a slide table 2, an iron base 3, and a rubber pad 4. Their specific positional relationship is as follows: the iron pad 1 is located above the rubber pad 4, the slide table 2 is located above the iron pad 1, and the top surface of the slide table 2 is in contact with the bottom surface of the switch rail. The iron base 3 is located above the iron pad 1 and to the left of the slide table 2. Two spraying devices are installed on the iron pad 1, one located on the front left side of the slide table and the other on the front right side. For ease of explanation, the spraying device located on the front left side is referred to as spraying device number one 5, and the spraying device located on the front right side is referred to as spraying device number two 6. Spraying device number one 5 and spraying device number two 6 communicate and interact with the turnout switching system via wired or wireless means. After the turnout switching system issues a turnout switching command, the spraying device first executes the spraying command, with either spraying device 5 (number one) or spraying device 6 (number two) spraying lubricant onto the slide plate. Only after the lubricant has been sprayed out will the turnout switch rail begin to switch. The entire spraying time is no more than 1.5 seconds and will not affect the turnout's switching efficiency. Whether spraying device 5 or spraying device 6 executes the spraying command depends on the specific position of the switch rail. If the switch rail is close to spraying device 5 after the turnout switching system issues a turnout switching command, spraying device 5 will not operate, and spraying device 6 will execute the spraying command. After execution, the turnout switch rail will begin to switch. If another turnout switching command is received, and spraying device 6 is close to the switch rail, spraying device 6 will not operate, and spraying device 5 will execute the spraying command. After execution, the turnout switch rail will begin to switch. This cycle continues, completing the lubricant spraying and turnout switching actions. This invention replaces the existing method of manually applying lubricating oil to the slide plate by installing a spraying device on the iron pad. This avoids the problem of fine sand and gravel blown by the train adhering to the slide plate surface after lubrication, which can cause deeper scratches after the switch rail is moved, further increasing the friction coefficient of the slide plate. The sprayed lubricant forms an oil film on the slide plate, providing excellent lubrication and effectively reducing the friction coefficient between the bottom of the switch rail and the slide plate. This reduces the switching force and under-displacement of the switch rail, and is more conducive to maintaining the geometry and position of the turnout rails. Equipping this invention eliminates the need for manual oiling of the slide plate, reducing the workload of track maintenance personnel and saving labor costs. Compared to manual oiling by track maintenance personnel, this invention only sprays before turnout switching, significantly reducing the amount of lubricant sprayed, which reduces the corrosive effect of oil on the rubber pad and increases the service life of the rubber pad.

[0020] In one specific embodiment of the present disclosure, the control of the first spraying device 5 and the second spraying device 6 can be controlled by the turnout conversion system, or a controller can be separately installed to control the spraying devices, and the controller communicates with the turnout conversion system to achieve linkage and execute the control logic described above.

[0021] In one specific embodiment of the present disclosure, the spraying devices are not limited to two, and more than two, such as four, can be selected, and one spraying device is installed on the rear left side and the rear right side of the sliding bed, respectively, as the third spraying device and the fourth spraying device. The first and third spraying devices work simultaneously, and the second and fourth spraying devices work simultaneously, as long as the spraying action of the lubricant described above can be achieved. Of course, the controller designed separately can be one controller to control all spraying devices, or one controller to connect one spraying device, and several controllers to connect several spraying devices, which are all within the protection scope of the present disclosure.

[0022] As shown in FIG. 1, Figure 5 In one specific embodiment of the present disclosure, the specific structure of the spraying device includes a base 7 and a nozzle 8, and the nozzle is installed on the base 7. The base 7 is a telescopic base. The telescopic base is prior art, and will not be described here. For example, a cylinder or an electric telescopic rod is installed on the base, and then the nozzle is installed on the cylinder or the electric telescopic rod to achieve the telescopic action. The storage of the lubricant can be set in the base, and the base is made into a container, and then the lubricant is stored in the base and connected to the nozzle 8 through a pipeline. Of course, a separate container can also be designed to contain the lubricant, and the pipeline is connected to the nozzle, as long as the supply of the lubricant can be achieved.

[0023] In one specific embodiment of the present disclosure, the base is made of iron, and the nozzle is made of flexible rubber. When receiving the spraying instruction, the nozzle extends to spray the lubricant, and after the spraying is completed, the nozzle is retracted, and the spraying instruction is completed. It should be noted that the height of the nozzle after extension is higher than the surface of the sliding bed, so that the lubricant can be sprayed on the sliding bed. After the nozzle is retracted, the height of the nozzle and the base is lower than the height of the sliding bed, so as not to interfere with the turnout conversion and complete the rotation action. At the same time, after the nozzle executes the spraying instruction, the nozzle is retracted, and then the turnout conversion instruction is executed, and the turnout switch rail starts to convert. The entire spraying time is not more than 1.5 seconds, which will not affect the conversion efficiency of the turnout itself.

[0024] In one specific embodiment of the present disclosure, all the connection lines of the device are fully fixed, and the system power is connected to the power supply system.

[0025] In one specific embodiment of the present disclosure, the rubber pad 4 is provided with a groove, and the iron pad 1 is arranged in the groove, the width of the iron pad 1 is the same as the width of the groove, the height of the iron pad 1 is the same as the depth of the groove, and the iron pad 1 has sufficient structural strength to withstand the impact force caused by the train running.

[0026] In one specific embodiment of the present disclosure, the lubricant is a high-lubricity quick-drying lubricant, such as a quick-drying lubricant (which is a lubricant containing polytetrafluoroethylene (PTFE) solid lubricating particles, can quickly evaporate on the surface of the lubricated part and form a uniform lubricating film, and also has the functions of waterproof, moisture-proof, corrosion-proof and cleaning), and P-80 Grip-it quick-drying rubber lubricant (produced by IPC Company in the United States, has a high temporary lubricating effect, and the lubricant will completely evaporate and disappear after the operation is completed, without leaving any traces). Due to the quick-drying property of the lubricant, the slide bed is dry most of the time, which can reduce the adhesion probability of fine sand to the slide bed and maintain the smooth state of the slide bed.

[0027] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
