Description

Technical Field

[0001] This utility model relates to the field of rail transit locomotive technology, specifically to a lubricated carbon sliding plate structure. Background Technology

[0002] Carbon sliding plates are used in rail transit vehicles, such as high-speed trains, electric locomotives, and subways. They are installed on the pantograph on the roof of the vehicle, making contact with the overhead power grid and conducting current to power the vehicle. The carbon sliding plates experience continuous contact and wear during operation; therefore, their current-carrying frictional properties are a key factor affecting their service life.

[0003] In recent years, an increasing number of abnormal wear incidents have occurred on carbon sliding plates in subway vehicles. One of the main reasons for this is the lack of lubrication between the carbon sliding plate and the friction pair. The main components of existing carbon sliding plates are graphite and carbon black. Graphite has good self-lubricating properties, but initially, a third-party medium such as water molecules or gas molecules is needed to act between the graphite layers to offset some of the interlayer attraction. When the operating environment changes, especially when the humidity decreases and the number of water molecules in the air decreases, the self-lubricating properties of graphite drop sharply, aggravating the wear and tear of the friction pair. This may lead to the carbon sliding plate breaking or falling off, thereby endangering the operating safety of subway vehicles. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the self-lubricating performance of carbon sliding plates in the prior art will drop sharply when the ambient humidity decreases, which will aggravate the wear and tear between the carbon sliding plate and the friction pair.

[0005] To address the aforementioned problems, this utility model provides a lubricated carbon slide plate structure, comprising a metal bracket and a carbon slide plate body mounted on the metal bracket. The top of the carbon slide plate body is provided with a contact working surface, and a lubrication structure is provided on the carbon slide plate body. The lubrication structure is configured as follows:

[0006] The carbon slide plate body is a porous and loose structure sintered at high temperature. The lubrication structure is formed by molten liquid lubricating material being impregnated into the gap of the carbon slide plate body and then cooled and solidified. When the carbon slide plate body is subjected to friction and heated to the melting point by electricity, the lubrication structure overflows in liquid form and acts on the friction pair.

[0007] Alternatively, the carbon slide body may have a lubrication position for installing a lubrication structure. The lubrication structure is formed by fixing a solid lubricating material at the lubrication position. The lubrication structure is continuously or intermittently arranged along the length of the carbon slide body and is flush with the contact working surface.

[0008] As a preferred embodiment, the lubrication structure is a paraffin lubrication structure formed by impregnating molten liquid paraffin into the porous structure of the carbon slide plate body and then cooling and solidifying it. The paraffin lubrication structure is solidified and bonded to the carbon slide plate body to form an integral structure.

[0009] As a preferred embodiment, the paraffin lubrication structure is partially melted by the heat generated by the heating of the carbon slide plate to form a lubricating film covering the carbon slide plate body and the contact working surface.

[0010] As a preferred embodiment, the paraffin lubrication structure includes a paraffin lubrication network formed by the cooling and solidification of liquid paraffin within the porous structure of the carbon slide body. This paraffin lubrication network undergoes a melting-solidification cycle under frictional heat and is used to dynamically replenish the lubrication film.

[0011] As a preferred embodiment, the lubrication location includes a plurality of recessed structures arranged along the length of the carbon slide body on the contact working surface. The lubrication structure includes a lubrication layer formed by filling the plurality of recessed structures with solid lubricating material, and the top of the lubrication layer is flush with the contact working surface.

[0012] As a preferred embodiment, the recessed hole structures are discontinuous and staggered on the contact working surface; or, the recessed hole structures are continuously arranged in a straight line or curve on the contact working surface.

[0013] As a preferred embodiment, the lubrication location includes a side mounting surface disposed on one side of the carbon slide plate body, and the lubrication structure includes a lubrication strip made of solid lubricating material and mounted on the side mounting surface. The lubrication strip extends along the length direction of the carbon slide plate body, and its height is flush with the height of the contact working surface.

[0014] As a preferred embodiment, the lubricating strip is detachably mounted on the side mounting surface via a connecting structure. The connecting structure includes a bracket plate connected to the metal bracket and located on one side of the carbon slide plate body, and fasteners for fixing the lubricating strip to the bracket plate and keeping it in close contact with the side mounting surface, so that the lubricating strip and the carbon slide plate body are connected as a whole.

[0015] As a preferred embodiment, the bracket plate has an L-shaped structure, and a limiting groove suitable for accommodating the lubricating strip is formed between the bracket plate and the carbon slide body.

[0016] As a preferred embodiment, the bracket plate and the metal bracket are fixedly connected by fasteners; or, the bracket plate and the metal bracket are integrally formed.

[0017] As a preferred embodiment, the carbon slide body and the metal bracket are bonded together as a whole using an adhesive.

[0018] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0019] 1. The lubricating carbon slide plate structure provided by this utility model has various configuration forms on the carbon slide plate body. One method involves impregnating molten liquid lubricating material into the porous structure of the carbon slide plate and then cooling and solidifying it to form the lubricating structure. Preferably, this lubricating structure uses a lubricating material with a low melting point. When the carbon slide plate is subjected to friction and heated by electricity to reach the melting point of the lubricating material, the lubricating structure overflows in a liquid state and acts on the friction pair, thereby improving the self-lubricating performance of the carbon slide plate. Another method involves processing solid lubricating material into a certain shape and then independently installing it at a preset lubrication position on the carbon slide plate to form the lubricating structure. This lubricating structure is connected to the contact... The working surfaces are kept flush, allowing the friction pair to simultaneously slide and connect the working surfaces and the lubrication structure, thereby improving the lubrication performance between the carbon slide plate and the friction pair. The carbon slide plate structure using this technical solution aims to improve the self-lubricating performance of the carbon slide plate by adding supplementary lubricating materials to compensate for the impact of reduced humidity and solve the problem of abnormal wear of the carbon slide plate. This lubrication structure has diverse settings and many options, is easy to implement in terms of structure and process, and has low cost. Laboratory wear tests have verified that, compared with ordinary carbon slide plates, it has a significant lubrication and friction reduction effect when the relative humidity is below 20%, thus improving the performance and service life of the carbon slide plate.

[0020] 2. In the lubricating carbon slide plate structure provided by this utility model, the carbon slide plate is sintered at high temperature to form a porous and loose structure. The lubricating material is preferably low-melting-point refined paraffin wax. That is, the lubricating structure is made of paraffin wax material and carbon slide plate as a whole through an impregnation process. Specifically, after the carbon slide plate is preheated, it is placed in a pre-melted paraffin wax pool. Through a pressure impregnation process, the paraffin wax enters the porous structure of the carbon slide plate. After cooling, it remains in a solid state, thus forming a lubricating structure on the carbon slide plate. This paraffin wax lubricating structure is solid at room temperature and has good lubricity. When the carbon slide plate is rubbed and heated by electricity to reach the melting point of paraffin wax, the paraffin wax overflows in a liquid state and plays a lubricating role on the friction pair. It will form a lubricating film on the contact working surface of the carbon slide plate, thereby reducing the friction coefficient between the carbon slide plate and the friction pair. This compensates for the decrease in the self-lubricating performance of the carbon slide plate after the humidity decreases, and greatly improves the self-lubricating performance of the carbon slide plate.

[0021] 3. In the lubricating carbon slide plate structure provided by this utility model, when liquid paraffin is introduced into the carbon slide plate through a pressure impregnation process and cooled and solidified to form a lubricating structure, a lubricating film is also formed on the contact working surface of the carbon slide plate. Furthermore, this paraffin lubricating structure will melt and overflow onto the contact working surface when the carbon slide plate is heated, thereby supplementing the contact working surface with lubricating material, improving the self-lubricating performance of the carbon slide plate, compensating for the impact of reduced humidity, reducing friction, and thus reducing wear between the carbon slide plate and the friction pair.

[0022] 4. In the lubricating carbon slide plate structure provided by this utility model, several concave structures are set on the contact working surface of the carbon slide plate body, and then solid lubricant is filled into the several concave structures to form several lubrication layers. The lubrication layers constitute a lubrication structure used together with the matching carbon slide plate. Since the lubrication layers are distributed along the length direction of the carbon slide plate body on the contact working surface, it is ensured that the entire contact working surface is filled with lubricating material. In addition, the top of the lubrication layer is flush with the contact working surface, ensuring that the friction pair can simultaneously contact the lubrication layer and the carbon slide plate during the sliding process of the contact working surface. This design helps to reduce the friction coefficient between the carbon slide plate and the friction pair, and can also compensate for the decrease in the self-lubricating performance of the carbon slide plate after the humidity decreases. It can also solve the problem of abnormal wear of the carbon slide plate and greatly improve the self-lubricating performance of the carbon slide plate.

[0023] 5. In the lubricated carbon slide plate structure provided by this utility model, the lubrication structure includes a lubricating strip made of solid lubricating material and installed on the side mounting surface. This lubricating strip extends along the length of the carbon slide plate body and is flush with the height of the contact working surface. This design ensures that lubricating material is arranged on the sliding path of the friction pair, ensuring that the friction pair can simultaneously contact the lubricating strip and the carbon slide plate during the sliding process. When the friction pair of the power supply network contacts the lubricating strip, the lubricating properties of the lubricating strip can produce a lubricating effect on the friction pair, thereby reducing the wear and tear between the carbon slide plate and the friction pair, thus solving the problem of abnormal wear of the carbon slide plate, improving the self-lubricating performance of the carbon slide plate, and extending the service life of the product.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1

[0037] The following is a detailed description of this embodiment with reference to the accompanying drawings:

[0038] This embodiment provides, as follows: Figure 1-2 The illustrated lubricated carbon slide plate structure includes a metal bracket 1 and a carbon slide plate body 2 mounted on the metal bracket 1. The top of the carbon slide plate body 2 is provided with a contact working surface 21, and a lubrication structure 3 is provided on the carbon slide plate body 2. The lubrication structure 3 is configured as follows:

[0039] The carbon slide plate body 2 is formed into a porous structure through high-temperature sintering, that is, several pore structures are formed inside the carbon slide plate body. The lubrication structure 3 is formed by impregnating molten liquid lubricating material into the pore structure of the carbon slide plate body 2 and then cooling and solidifying it. When the carbon slide plate body 2 is subjected to friction and heated to its melting point by electric current, the lubrication structure 3 overflows in a liquid state and acts on the friction pair. The carbon slide plate structure using this technical solution aims to improve the self-lubricating performance of the carbon slide plate by adding supplementary lubricating material, so as to compensate for the impact of reduced humidity and solve the problem of abnormal wear of the carbon slide plate. Through laboratory wear tests, compared with ordinary carbon slide plates, it has a significant lubrication and friction reduction effect when the relative humidity is below 20%, thus improving the performance and service life of the carbon slide plate.

[0040] The specific arrangement of the lubrication structure 3 is described in detail below:

[0041] The lubrication structure 3 is a paraffin lubrication structure 31 formed by impregnating molten liquid paraffin into the porous structure of the carbon slide plate body 2 and then cooling and solidifying it. The paraffin lubrication structure 31 and the carbon slide plate body 2 are solidified and bonded together to form an integral structure. This structure is designed so that the carbon slide plate is sintered at high temperature to form a porous and loose structure. The lubricating material is preferably low-melting-point refined paraffin. That is, the lubrication structure 3 is made of paraffin material and the carbon slide plate into a whole through an impregnation process. Specifically, the carbon slide plate is preheated and placed in a pre-molten paraffin bath. Through a pressure impregnation process, the liquid paraffin enters the carbon slide plate body 2. The porous structure of the carbon slide plate remains in a solid state after cooling, thus forming a lubrication structure 3 on the carbon slide plate body 2. This paraffin lubrication structure 31 is solid at room temperature and has good lubricity. When the carbon slide plate is rubbed and heated to the melting point of paraffin, the paraffin becomes liquid and overflows to lubricate the friction pair. It forms a lubricating film on the contact working surface 21 of the carbon slide plate, thereby reducing the friction coefficient between the carbon slide plate and the friction pair. This compensates for the decrease in the self-lubricating performance of the carbon slide plate after the humidity decreases, effectively solves the problem of abnormal wear of the carbon slide plate, and greatly improves the self-lubricating performance of the carbon slide plate.

[0042] In a further preferred configuration, based on the fact that the carbon slide plate will heat up due to friction and electricity, the paraffin lubrication structure will partially melt under the heat generated by the heated carbon slide plate to form a lubricating film covering the carbon slide plate body and the contact working surface 21. The paraffin lubrication structure includes a paraffin lubrication network formed by the cooling and solidification of liquid paraffin in the pore structure of the carbon slide plate body. The paraffin lubrication network melts and solidifies under the action of frictional heat and is used to dynamically replenish the lubricating film. With this structural configuration, when liquid paraffin is introduced into the interior of the carbon slide plate through a pressure impregnation process and cooled and solidified to form the paraffin lubrication structure, it will also cover and form a lubricating film on the contact working surface 21 of the carbon slide plate. Furthermore, this paraffin lubrication structure 31 will melt and overflow onto the contact working surface 21 under the heat generated by the heated carbon slide plate, thereby replenishing the contact working surface 21 with lubricating material, thus forming a continuous lubricating film. This lubricating film has self-repairing ability, improves the self-lubricating performance of the carbon slide plate, compensates for the effect of reduced humidity, reduces friction, and thus reduces wear between the carbon slide plate and the friction pair.

[0043] In this embodiment, a paraffin impregnation process is used on a carbon sliding plate to fill the pores of the carbon matrix with paraffin, forming a solid paraffin lubricating structure. Firstly, this paraffin lubricating structure has excellent lubrication performance, reducing the coefficient of friction and decreasing wear on the carbon sliding plate and friction pair. Secondly, the paraffin lubricating structure has self-healing lubrication capabilities. During the friction process of the carbon sliding plate, localized high temperatures melt the solid paraffin within the pores and allow it to seep to the surface, forming a continuous lubricating film. This ensures the lubricating film can continuously cover the contact working surface at a constant temperature. After cooling, the paraffin re-solidifies, achieving dynamic repair of the lubrication layer and extending its service life. The lubrication structure formed by the paraffin impregnation process has long-lasting self-lubricating properties, reducing maintenance frequency and costs. Furthermore, this paraffin lubricating structure has good environmental adaptability, environmental friendliness, and economy. Paraffin remains solid at low and normal temperatures, avoiding lubrication failure caused by low-temperature solidification of traditional grease lubricants. Additionally, paraffin is non-toxic and biodegradable, avoiding environmental pollution from the volatilization or leakage of traditional lubricating greases, aligning with the green development trend of rail transit. Moreover, paraffin raw materials are inexpensive, and the impregnation process is simple.

[0044] Example 2

[0045] This embodiment provides, as follows: Figure 3-4The illustrated lubrication-enhanced carbon slide plate structure includes a metal bracket 1 and a carbon slide plate body 2 mounted on the metal bracket 1. The top of the carbon slide plate body 2 has a contact working surface 21, and a lubrication structure 3 is provided on the carbon slide plate body 2. This lubrication structure 3 differs from that in Embodiment 1 by using a solid lubricating material installed at a predetermined lubrication position on the carbon slide plate. The solid lubricating material utilizes solid powder with added lubricating components (such as graphene, lead, and molybdenum dioxide) to reduce friction and wear on the bearing surface. Specifically, the carbon slide plate body 2 has lubrication positions for mounting the lubrication structure 3, located along the movement path of the friction pair. The lubrication structure 3 is formed by fixing the solid lubricating material at the lubrication position. This lubrication structure 3 is continuously or intermittently arranged along the length direction of the carbon slide plate body 2 and remains flush with the contact working surface 21. This design allows the friction pair to simultaneously slide into contact with both the working surface 21 and the lubrication structure 3, thereby improving the lubrication performance between the carbon slide plate and the friction pair. The carbon slide plate structure employing this technical solution aims to enhance its self-lubricating performance by adding supplementary lubricating materials to compensate for the effects of reduced humidity and address the problem of abnormal wear. This lubrication structure offers diverse configuration options, is easy to implement, and has low cost. Laboratory wear tests have verified that, compared to ordinary carbon slide plates, it exhibits a significant lubrication-enhancing and friction-reducing effect when the relative humidity is below 20%, thus improving the performance and service life of the carbon slide plate.

[0046] The following is combined Figure 3-4 The specific configuration of the lubrication structure in this embodiment will be described in detail below:

[0047] The lubrication points include a plurality of recessed hole structures 22 arranged along the length of the carbon slide body 2 on the contact working surface 21. The lubrication structure 3 includes a lubrication layer 32 formed by filling the plurality of recessed hole structures 22 with solid lubricating material. The top of the lubrication layer 32 is flush with the contact working surface 21. The plurality of recessed hole structures 22 are discontinuous and staggered on the contact working surface 21; or, the plurality of recessed hole structures 22 are continuously arranged in a straight line or curve on the contact working surface 21. This ensures that the lubrication layer 32 filled in the recessed hole structures 22 covers the entire contact working surface 21. These recessed hole structures 22 can be round holes, elliptical holes, square holes, irregular holes, etc., and the depth of the recessed holes does not penetrate the entire thickness of the carbon slide body, and is set according to actual application requirements. The advantage of this embodiment is that by setting several recessed hole structures 22 on the contact working surface of the carbon slide plate body 2, and then filling the several recessed hole structures 22 with solid lubricant to form several lubrication layers 32, the lubrication layers 32 constitute the lubrication structure 3 used in conjunction with the carbon slide plate. Since the lubrication layers 32 are distributed along the length direction of the carbon slide plate body 2 on the contact working surface 21, it is ensured that the entire contact working surface 21 is filled with lubricating material. In addition, the top of the lubrication layer 32 is flush with the contact working surface 21, ensuring that the friction pair can simultaneously contact the lubrication layer 32 and the carbon slide plate during the sliding process of the contact working surface 21. When the friction pair of the power supply network contacts the lubrication layer 32, the lubrication layer can lubricate the friction pair. This design helps to reduce the friction coefficient between the carbon slide plate and the friction pair, and can also compensate for the decrease in the self-lubricating performance of the carbon slide plate after the humidity decreases. It can also solve the problem of abnormal wear of the carbon slide plate and greatly improve the self-lubricating performance of the carbon slide plate.

[0049] This embodiment provides, as follows: Figure 5-6The illustrated lubrication-enhanced carbon slide plate structure includes a metal bracket 1 and a carbon slide plate body 2 mounted on the metal bracket 1. The top of the carbon slide plate body 2 has a contact working surface 21, and a lubrication structure 3 is provided on the carbon slide plate body 2. A lubrication position for mounting the lubrication structure 3 and located on the friction pair's motion path is also provided on the carbon slide plate body 2. The difference between this embodiment 3 and embodiment 2 lies in the mounting position and arrangement of the lubrication structure 3 on the carbon slide plate. Specifically, the lubrication position includes a side mounting surface 23 located on one side of the carbon slide plate body 2, and the lubrication structure 3 includes... The device includes a lubricating strip 33 made of solid lubricating material and mounted on the side mounting surface 23. The lubricating strip 33 extends along the length of the carbon slide plate body 2, and its height is flush with the height of the contact working surface 21. This design ensures that the friction pair can simultaneously contact the lubricating strip 33 and the carbon slide plate during sliding. When the friction pair of the power supply network contacts the lubricating strip 33, the lubricating properties of the lubricating strip 33 can lubricate the friction pair, thereby reducing the wear and tear between the carbon slide plate and the friction pair, thus solving the problem of abnormal wear of the carbon slide plate, improving the self-lubricating performance of the carbon slide plate, and extending the service life of the product.

[0050] In a preferred embodiment, the lubricating strip 33 is detachably mounted on the side mounting surface 23 via a connecting structure. The connecting structure includes a bracket plate 4 connected to the metal bracket 1 and located on one side of the carbon slide body 2, and a fastener 5 that fixes the lubricating strip 33 on the bracket plate 4 and keeps it in close contact with the side mounting surface 23. The fastener 5 is preferably a screw or rivet, etc., and a fixing hole is provided on the lubricating strip 33 to cooperate with the fastener 5, so that the lubricating strip 33 is connected to the carbon slide body 2 as a whole. The carbon slide body 2 and the metal bracket 1 are bonded together by adhesive, and the bracket plate 4 and the metal bracket 1 are fixedly connected by the fastener 5. Alternatively, the bracket plate 4 and the metal bracket 1 are integrally formed. This bracket plate 4 has an L-shaped structure, and a limiting groove suitable for accommodating the lubricating strip 33 is formed between the bracket plate 4 and the carbon slide body 2. The limiting groove plays a role in pre-positioning and installing the lubricating strip 33. In this structural design, the lubricating strip 33 is integrally connected and fixed to the carbon slide body 2 through the bracket plate 4 and fasteners 5. The installation structure is simple, the connection and fixation are reliable, and the installation is convenient and quick. Of course, the lubricating strip 33 can also be fixed to the side mounting surface 23 of the carbon slide lifting mechanism by snap-fit ​​or adhesive.
