Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of turnouts, and particularly to an oil injection device for a turnout system. Background Art
[0002] A turnout system generally includes a turnout and a switch machine, both of which need to be oiled and lubricated during use to ensure the normal operation of the turnout system. In the related art, the current oil injection device generally includes an oil storage pot, in which lubricating oil is provided, and an oil injection valve is provided at the bottom of the oil storage pot. However, when the oil storage pot is arranged in some humid environments or in areas with large temperature differences between day and night, condensed water is likely to form in the oil storage pot. Since the density of this condensed water is greater than that of the lubricating oil, it will deposit at the bottom of the oil storage pot, resulting in the lubricating oil dripping through the oil injection valve containing condensed water, which affects the oil injection effect of the oil injection device. Summary of the Utility Model
[0003] The purpose of the present disclosure is to provide an oil injection device for a turnout system, which can reduce or even avoid the lubricating oil dripping through the oil injection valve containing condensed water and improve its own oil injection effect.
[0004] To achieve the above purpose, the present disclosure provides an oil injection device for a turnout system, which includes an oil storage pot, an oil injection valve and a drainage structure. The oil injection valve is communicated with the bottom of the oil storage pot. The drainage structure includes a drainage pipe, which has a first branch pipe extending into the oil storage pot and a second branch pipe extending out of the oil storage pot. The first branch pipe abuts against the bottom wall surface of the oil storage pot, and a drainage port communicating with the oil storage pot is opened at the bottom of the first branch pipe. The opening direction of the drainage port is perpendicular to the up-down direction, and an outlet is opened on the second branch pipe.
[0005] Optionally, both the first branch pipe and the second branch pipe extend in the vertical direction, and the outlet is opened at the top of the second branch pipe.
[0006] Optionally, a sealing plug is provided at the outlet.
[0007] Optionally, the drainage structure includes an opening and closing member, which is arranged on the oil storage pot and is used to selectively open the drainage port.
[0008] Optionally, the oil storage pot has a bottom plate, which has the bottom wall surface. A fitting port is opened on the bottom plate. The opening and closing member has a stud and a sealing portion connected to the stud. The stud is threadedly connected at the fitting port, and the sealing portion is sealingly fitted at the drainage port.
[0009] Optionally, the opening and closing member includes a head connected to the stud, and a gasket is provided between the head and the oil storage pot, and the gasket is used to provide a seal between the head and the oil storage pot.
[0010] Optionally, the bottom plate has a first sub-plate and a second sub-plate arranged at an angle, and the first sub-plate and the second sub-plate gradually approach each other from top to bottom. Wherein, a third sub-plate is connected between the bottom end of the first sub-plate and the bottom end of the second sub-plate, and the third sub-plate has the bottom wall surface and the mating port.
[0011] Optionally, the included angle between the first sub-plate and the second sub-plate is an obtuse angle.
[0012] Optionally, the first branch pipe and the second branch pipe are integrally formed.
[0013] Through the above technical solution, in the oil injection device of the turnout system provided by the present disclosure, since the first branch pipe abuts against the bottom wall surface and a drain port is opened at the bottom of the first branch pipe, therefore, the condensed water at the bottom of the oil storage pot can enter the first branch pipe through the drain port and be discharged through the outlet. Thus, the timely discharge of the condensed water in the oil storage pot can be realized, that is, the oil injection device of the present disclosure can reduce or even avoid the lubricating oil dripping through the oil injection valve containing condensed water and improve its own oil injection effect. In addition, setting the drain port close to the bottom wall surface can also reduce the loss of lubricating oil in the oil storage pot during drainage. Thus, the normal operation of the oil injection device can be ensured. In addition, by partially inserting the drain pipe into the oil storage pot, the stability of the drain pipe itself can be improved and the anti-vibration performance of the drain pipe can be enhanced.
[0014] Other features and advantages of the present disclosure will be described in detail in the subsequent specific implementation part. Description of the Drawings

Detailed implementation manners
[0020] The following will describe in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present disclosure, and are not used to limit the present disclosure.
[0021] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are defined based on Figure 1 and Figure 2 the drawing direction of the drawing. Among them, the up - down direction can also refer to the gravity direction of the oil filling device. In addition, "upper" corresponds to "top", and "lower" corresponds to "bottom". "Inner and outer" refer to the inside and outside of the contour of each component. The terms "first, second" are used to distinguish one element from another, and do not have an order or importance. In addition, when the following description refers to the accompanying drawings, the same reference numerals in different drawings represent the same or similar elements, and the present disclosure will not repeat them.
[0022] According to some embodiments of the present disclosure, an oil filling device for a turnout system is provided. As shown in Figure 1 and Figure 2 , the oil filling device includes an oil storage pot 1, an oil filling valve 2, and a drainage structure 3. The oil filling valve 2 is connected to the bottom of the oil storage pot 1. The drainage structure 3 includes a drain pipe 31. The drain pipe 31 has a first branch pipe 311 extending into the oil storage pot 1 and a second branch pipe 312 extending out of the oil storage pot 1. The first branch pipe 311 abuts against the bottom wall surface 11 of the oil storage pot 1, and a drainage port 313 communicating with the oil storage pot 1 is opened at the bottom of the first branch pipe 311. The opening direction of the drainage port 313 is perpendicular to the up - down direction. An outlet 314 is opened on the second branch pipe 312.
[0023] With the above technical solution, in the oil injection device of the turnout system provided in the present disclosure, since the first branch pipe 311 abuts against the bottom wall surface 11 and a drain port 313 is provided at the bottom of the first branch pipe 311, the condensed water at the bottom of the oil storage pot 1 can enter the first branch pipe 311 through the drain port 313 and be discharged through the outlet 314. Thus, the timely discharge of the condensed water in the oil storage pot 1 can be achieved, that is, the oil injection device of the present disclosure can reduce or even avoid the lubricating oil dripping through the oil injection valve 2 containing condensed water, improving its own oil injection effect. In addition, by arranging the drain port 313 close to the bottom wall surface 11, the loss of the lubricating oil in the oil storage pot 1 can also be reduced during drainage, thus ensuring the normal operation of the oil injection device. Furthermore, by partially inserting the drain pipe into the oil storage pot, the stability of the drain pipe itself can be improved and its vibration resistance can be enhanced.
[0024] In some embodiments of the present disclosure, as shown in reference to Figure 1 and Figure 2 , both the first branch pipe 311 and the second branch pipe 312 extend in the vertical direction, and an outlet 314 is provided at the top of the second branch pipe 312. The advantage of this arrangement is that it can prevent the lubricating oil in the oil storage pot 1 from accidentally leaking through the drain pipe 31 when the first branch pipe 311 and the second branch pipe 312 are horizontally arranged. Among them, in some embodiments, a drainage pump can be provided at the outlet 314 to pump out the condensed water at the bottom of the oil storage pot 1 through the drain pipe 31, achieving the timely discharge of the condensed water in the oil storage pot 1. Of course, in other embodiments, a liquid suction pipe can also be inserted into the first branch pipe 311 to manually suck out the condensed water, and the present disclosure does not limit this too much.
[0025] In some embodiments of the present disclosure, as shown in reference to Figure 1 and Figure 2 , a sealing plug 32 can be provided at the outlet 314. In this way, after the drainage is completed, the outlet 314 can be closed by using the sealing plug 32 to prevent external impurities, dust, etc. from entering the oil storage pot 1 and causing pollution to the lubricating oil.
[0026] In some embodiments of the present disclosure, as shown in reference to Figure 1 and Figure 2 , the drainage structure 3 can include an opening and closing member 33, and the opening and closing member 33 is arranged on the oil storage pot 1 and is used to selectively open the drain port 313. In this way, when drainage is required, the drain port 313 can be opened by using the opening and closing member 33, and after the drainage is completed, the drain port 313 can be closed by using the opening and closing member 33. In this way, it can be avoided that the drain port 313 is always open, causing the lubricating oil to enter the drain pipe 31 through the drain port 313.
[0027] In some embodiments of the present disclosure, as shown in reference to Figure 1 and Figure 2As shown, the oil storage pot 1 may have a bottom plate 12, the bottom plate 12 has a bottom wall surface 11, a mating port is formed on the bottom plate 12, the opening and closing member 33 has a stud 331 and a sealing portion 332 connected to the stud 331, the stud 331 is threadedly connected at the mating port, and the sealing portion 332 is sealingly fitted and sealed at the drain port 313. In this way, by rotating the stud 331, the selective sealing of the drain port 313 by the sealing portion 332 can be achieved, with a simple structure and easy operation. After the stud 331 is tightened, the sealing portion 332 can reliably seal the drain port 313, thus improving the working stability of the oil injection device. Among them, the shape of the sealing portion 332 can be adaptively designed according to needs, and the present disclosure does not limit this. In addition, in actual arrangement, the drain port 313 can be arranged as close as possible to the bottom wall surface 11, so as to improve the drainage effect of the condensed water and reduce the loss of lubricating oil during drainage.
[0028] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 As shown, the opening and closing member 33 includes a head 333 connected to the stud 331, and a sealing gasket is provided between the head 333 and the oil storage pot 1, and the sealing gasket is used to provide sealing between the head 333 and the oil storage pot 1. In this way, the reliable sealing between the bolt and the oil storage pot 1 can be achieved by using the sealing gasket, avoiding oil leakage at the mating port.
[0029] In some embodiments of the present disclosure, referring to Figure 2 As shown, the bottom plate 12 has a first sub - plate 121 and a second sub - plate 122 arranged at an angle, the first sub - plate 121 and the second sub - plate 122 gradually approach each other from top to bottom. Among them, a third sub - plate 123 is connected between the bottom end of the first sub - plate 121 and the bottom end of the second sub - plate 122, and the third sub - plate 123 has a bottom wall surface 11 and a mating port. In this way, by the inclined arrangement of the first sub - plate 121 and the second sub - plate 122, the condensed water in the oil storage pot 1 can be gathered at the third sub - plate 123, thus further reducing the loss of lubricating oil during drainage.
[0030] In some embodiments, referring to Figure 2 As shown, the included angle between the first sub - plate 121 and the second sub - plate 122 is an obtuse angle. In this way, the height of the first sub - plate 121 and the second sub - plate 122 in the up - and - down direction can be reduced, and thus the volume of the oil storage pot 1 can be reduced, which is beneficial to arranging the oil injection device on the turnout system.
[0031] In some embodiments of the present disclosure, the oil injection valve 2 can be configured as an electromagnetic switch valve, and the present disclosure does not limit this.
[0032] In some embodiments, the first branch pipe 311 may be integrally formed with the second branch pipe 312. In this way, the connection between the first branch pipe 311 and the second branch pipe 312 can be omitted, the number of components of the oil injection device can be reduced, and it is beneficial to simplify the assembly of the oil injection device.
[0033] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0034] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.
[0035] Furthermore, any combination can be made between various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
