Description

Technical Field

[0001] The invention relates to the technical field of current collector and icebreaker technology, in particular to a combined current collector shoe slide plate. Background Art

[0002] The collector shoe skateboard directly contacts the contact network, draws electricity from the contact network, and transmits the electricity to the train for the train to use. As a key core component of the train, the material selection and installation of the collector shoe skateboard directly affect the safety and efficiency of the train operation. At present, the mainstream material of the collector shoe skateboard is metal-impregnated carbon material. In rainy and snowy cold weather, the contact network conductive rails exposed on the road surface are prone to ice formation. The hardness of ice is greater than the hardness of the carbon skateboard itself. After the two collide, it is easy to cause the carbon skateboard to break and fall off, resulting in abnormal ignition. At the same time, the conductive rails are attached with ice, making it impossible for the skateboard to obtain electricity from the conductive rails, thereby causing the train to lose its running power, thereby causing a series of unsafe accidents such as train suspension. How to break the frost attached to the surface of the conductive rails while protecting the carbon skateboard without damaging the conductive rails is the key to solving this problem. Therefore, some deicing skateboards have appeared on the market, but the current deicing skateboards simply scrape the surface of the contact network conductive rails. The scraped ice layer is easy to accumulate on the surface, which greatly affects its force. At the same time, because the temperature conductivity inside is not high, the deicing mechanism has a very limited de-icing effect. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the existing deicing skateboard easily accumulates the scraped ice layer on the surface, which greatly affects its force, and the internal temperature conductivity is not high, resulting in a very limited ice melting effect of the deicing mechanism.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a combined collector shoe skateboard, including a deicing component, a lubrication component and an assembly bracket, the outer edge positions of the assembly bracket are provided with upwardly bent lateral limit baffles, the lubrication component is installed and limited in the middle position of the upper surface of the assembly bracket, deicing components are arranged on both sides of the lubrication component, the lubrication component includes a bottom mounting unit and an upper lubrication block installed on the bottom mounting unit, the bottom mounting unit has a rectangular operating groove on the lower surface, the bottom mounting unit has an inner heat equalizing runner with openings on both sides, the deicing component has a lateral heat equalizing runner matched with the inner heat equalizing runner, and the rectangular operating groove is movably equipped with a self-weight external drive device.

[0005] The bottom mounting unit has lateral guide nozzles on both sides that protrude outward and are connected to the inner heat-distributing flow channel. The de-icing component connection surface is provided with lateral assembly expansion holes that cooperate with the lateral guide nozzles. The inner heat-distributing flow channel is connected to the lateral heat-distributing flow channel by inserting the lateral guide nozzles into the lateral assembly expansion holes.

[0006] The inner heat-averaging channel includes a first return channel, a second return channel, a first drain channel and a second drain channel.

[0008] A screw groove for fixing is provided on the upper inclined surface of the deicing component, and screw installation through holes are provided on the bottom surface of the screw groove and at corresponding positions inside the assembly bracket.

[0009] The deicing component and the bottom mounting unit are both provided with lateral limiting grooves matched with the lateral limiting baffles.

[0010] The inner walls on both sides of the rectangular operating slot are symmetrically provided with arc-shaped assembly grooves for installing a self-weight external driving device.

[0011] The self-weight type external driving device comprises an internal driving impeller arranged inside the central guide chamber, an external driving wind wheel arranged inside the arc-shaped assembly groove, and a synchronous fixed shaft.

[0012] The deicing components on both sides of the lubrication component are designed with a slope that gradually descends from the inside to the outside, and the angle of the slope is 10 to 45 degrees.

[0013] The upper end of the bottom mounting unit is provided with an upwardly protruding upper assembly convex strip, and the lower surface of the upper lubrication block is provided with a bottom assembly slot matched with the upper assembly convex strip.

The two channels are interconnected through lateral guide nozzles, which greatly improves the heat conduction efficiency between the components and increases the ice melting effect on both sides; (5) The lubrication component consists of a bottom mounting unit and an upper lubrication block mounted on the bottom mounting unit.

These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 , Figure 2 and Figure 3 A combined collector shoe skateboard is shown, comprising a deicing component 1, a lubricating component 2 and an assembly bracket 3. The outer edges of the assembly bracket 3 are provided with upwardly bent lateral limit baffles 4. The lubricating component 2 is installed and limited in the middle of the upper surface of the assembly bracket 3. Deicing components 1 are arranged on both sides of the lubricating component 2. The lubricating component 2 comprises a bottom mounting unit 21 and an upper lubricating block 22 mounted on the bottom mounting unit 21. A rectangular operating groove 5 is provided on the lower surface of the bottom mounting unit 21. An inner heat-balancing runner 6 with openings on both sides is provided inside the bottom mounting unit 21. A lateral heat-balancing runner 7 cooperating with the inner heat-balancing runner 6 is provided inside the deicing component 1. A self-weight external driving device 8 is movably assembled inside the rectangular operating groove 5.

[0022] Operating principle: When the train is running, the frost attached to the surface of the conductive rail will be removed by the deicing component 1, and the wind will blow into the rectangular operating slot 5 to drive the self-weight external drive device 8, and then the heat exchange fluid inside the inner heat equalizing channel 6 will be introduced into the lateral heat equalizing channel 7, and the heat generated by the lubricating component 2 during contact will be introduced into the deicing component 1. The defrosting and ice melting efficiency can be improved by improving the heat clamp of the deicing component 1, and then it will be discharged along the outside.

[0023] In order to cooperate with the lateral assembly connection, the bottom mounting unit 21 has lateral guide nozzles 23 on both sides that protrude outward and are connected to the inner heat equalizing flow channel 6. The connecting surface of the de-icing component 1 is provided with lateral assembly expansion holes 24 that cooperate with the lateral guide nozzles 23. The inner heat equalizing flow channel 6 is inserted into the lateral assembly expansion holes 24 through the lateral guide nozzles 23 and is connected to the lateral heat equalizing flow channel 7.

[0024] The bottom mounting unit 21 is inserted into the lateral assembly expansion hole 25 through the lateral guide nozzle 23 and is plugged and limited with the deicing component 1.

[0025] In order to cooperate with the internal flow guidance, the inner heat equalizing channel 6 includes a first return channel 61 , a second return channel 62 , a first flow discharge channel 63 and a second flow discharge channel 64 .

[0026] In order to facilitate flow guidance and assembly, a central flow guidance chamber 65 for installing the self-weight external driving device 8 is provided between the first return channel 61 and the first discharge channel 63 and between the second return channel 62 and the second discharge channel 64 .

[0027] In order to cooperate with the lateral bolt fixation, a screw groove 9 for fixation is opened on the upper inclined surface of the deicing component 1, and screw installation through holes 10 are opened on the inner bottom surface of the screw groove 9 and the corresponding position inside the assembly bracket 3.

[0028] The screw slot 9 can also conveniently increase the heat dissipation area and increase ice accumulation.

[0029] In order to improve the assembly firmness of the lateral limit baffle 4 , lateral limit grooves 11 matching with the lateral limit baffle 4 are provided on both sides of the de-icing component 1 and the bottom mounting unit 21 .

[0030] The lateral limiting baffle 4 is bent upward and inserted into the lateral limiting groove 11 , thereby fixing and limiting the de-icing component 1 and the bottom mounting unit 21 .

[0031] During disassembly, the deicing component 1 and the bottom mounting unit 21 are separated by flipping the lateral limiting baffle 4 outward.

[0032] In order to cooperate with the driving and facilitate the normal driving of the self-weight external driving device 8, arc-shaped assembly grooves 12 for installing the self-weight external driving device 8 are symmetrically opened on the inner walls on both sides of the rectangular operating slot 5.

[0033] In order to cooperate with the driving, the self-weight external driving device 8 is provided with an internal driving impeller 81 inside the central guide chamber 65, an outer driving impeller 82 inside the arc-shaped assembly groove 12 and a synchronous fixed shaft 83.

[0034] When the train is running, the generated wind pressure is blown into the rectangular operating slot 5 through the air vents inside the lateral limit baffle 4, and then blows the outer driving wind wheels 82 located on both sides, and then the outer driving wind wheels 82 drive the internal driving impellers 81 to rotate synchronously through the synchronous fixed shaft 83, and the internal driving impellers 81 are used to introduce the heat-averaging liquid inside the first return channel 61 into the first discharge channel 63 through the central guide chamber 65, and then the heat-averaging liquid inside the second return channel 62 is introduced into the second discharge channel 64 through the central guide chamber 65. When the lateral guide nozzle 23 is inserted into the lateral assembly expansion hole 24, the inner heat-averaging flow channel 6 is connected to the lateral heat-averaging flow channel 7 to form a circulation flow channel, and then the heat generated by the lubrication component 2 can be quickly introduced into the deicing component 1 on both sides, thereby increasing the heat of the deicing component 1, thereby quickly melting the scraped ice layer on the surface.

[0035] In order to improve safety, the deicing components 1 on both sides of the lubrication component 2 adopt a slope design that gradually descends from the inside to the outside, and the slope angle is 10~45 degrees.

[0036] The de-icing component 1 adopts a slope design, taking into account the warping of the conductive rail connection, reducing the collision between the right-angle part of the slider and the warped part of the conductive rail, and fully protecting the conductive rail.

[0037] In order to cooperate with the plug-in fixation, the upper end of the bottom mounting unit 21 has an upwardly protruding upper assembly convex strip 25, and the lower surface of the upper lubrication block 22 is provided with a bottom assembly slot that matches the upper assembly convex strip 25.

[0038] The bottom mounting unit 21 is laterally inserted into the bottom assembly slot through the upper assembly convex strip 25 and plugged and fixed with the upper lubrication block 22, and then the de-icing component 1 is attached to both sides of the lubrication component 2, and the openings on both sides of the bottom assembly slot are made, and then the lateral limit baffles 4 bent upward at the edges of the outer sides of the assembly bracket 3 are used to clamp the de-icing component 1 on the lubrication component 2 from all sides.

[0039] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
