Description

Technical Field

[0001] This utility model relates to the field of carbon sliding plate technology, specifically to an anti-arc carbon sliding plate structure. Background Technology

[0002] Carbon contact plates are key components of pantographs, primarily used in electric locomotives and urban rail transit vehicles. Installed at the head of the pantograph, their main function is to directly contact the overhead contact line, transferring electrical energy from the line to the electrical equipment within the locomotive to drive the vehicle. During operation, the carbon contact plate maintains sliding friction contact with the contact line while ensuring good conductivity, which is fundamental for stable power supply. The carbon contact plate is mainly composed of carbon materials, which inherently possess excellent electrical conductivity, enabling efficient current transmission. For example, graphite is a common component in carbon contact plate materials; its crystal structure contains freely moving electrons that can move directionally under the influence of an electric field, thus facilitating energy transfer.

[0003] A search revealed that Chinese Patent Publication No. CN208881598U discloses a carbon strip skateboard, comprising a carbon strip and a bracket. The lower surface of the carbon strip has a groove extending through it along its length. The connecting section of the bracket is embedded and bonded within the carbon strip groove. The first bonding surface of the carbon strip groove, extending along the width direction of the carbon strip, is a curved surface with corrugations or embossed textures to increase friction. The first bonding surface of the bracket connecting section, extending along its width direction, is a curved surface with corrugations or embossed textures that matches the first bonding surface of the carbon strip. This novel carbon strip skateboard has a simple structure, fewer manufacturing steps, increases the effective thickness of the carbon strip, extends the service life of the carbon strip, and has a large contact area with the carbon strip bracket, firmly embedding the bracket and preventing the carbon strip from tipping over, thus improving safety.

[0004] However, this device also has the following drawbacks: Because the rigid contact wire has a fixed height, the drastic change in the height of the contact wire during the transition between the rigid and flexible contact wires leads to a sharp increase in the carbon contactor disconnection rate. The increased disconnection results in more electric arcs and longer arc durations between the contact wire and the carbon contactor, which in turn increases the electrical wear between the carbon contactor and the contact wire, reducing the service life of the carbon contactor. This device does not solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide an anti-arc carbon sliding plate structure. By setting a nylon arc-extinguishing strip, when a large arc is generated, the nylon arc-extinguishing strip will be rapidly eroded by the large arc to generate a large amount of gas, reducing the charged ions in the air to a certain density, suppressing the large arc formed by the jumping of the carbon sliding plate, thereby reducing the electrical wear of the device and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An anti-arc carbon sliding plate structure includes an aluminum bracket body, the aluminum bracket body includes an aluminum profile, the two sides of the aluminum profile are provided with an insulating coating, and the top two sides of the aluminum profile are integrally formed with a clamping plate. It also includes a carbon strip body, which includes a main structure. The bottom of the main structure is connected to the aluminum bracket body by a card plate, and the top of the main structure is provided with a slanted groove. It also includes nylon arc-extinguishing strips, which are fixedly installed inside the inclined groove.

[0007] Preferably, the aluminum profile has a first cavity and two sets of second cavities inside, with the first cavity located between the two sets of second cavities.

[0008] Preferably, multiple sets of mounting columns are fixedly installed in the first cavity, and the bottom of each mounting column is provided with a mounting hole.

[0009] Preferably, a fixing screw is installed in the internal thread of the mounting hole, and the fixing screw is located below the aluminum bracket body.

[0010] Preferably, multiple sets of limiting strips are provided between the card plates, and the limiting strips are integrally formed with the aluminum profile.

[0011] Preferably, the bottom of the carbon strip body has multiple sets of limiting grooves, and the limiting grooves are engaged with the limiting strips.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model incorporates a nylon arc-extinguishing strip, which is simple in structure and convenient to use. When a large electric arc is generated, the nylon arc-extinguishing strip will be rapidly eroded by the large electric arc, generating a large amount of gas. This reduces the density of charged ions in the air to a certain level, suppressing the large electric arc formed by the jumping of the carbon slide plate, thereby reducing the electrical wear of the device and improving its service life.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 This utility model provides a technical solution: The anti-arc carbon slide plate structure includes an aluminum bracket body 1, which includes an aluminum profile 101. Insulating coatings 102 are provided on both sides of the aluminum profile 101. The top two sides of the aluminum profile 101 are integrally formed with clamping plates 103. It also includes a carbon strip body 2, which includes a main structure 201. The bottom of the main structure 201 is clamped to the aluminum bracket body 1 through the clamping plates 103.

[0017] By setting the carbon strip body 2 to be in direct contact with the contact network, the electrical energy on the contact network can be conducted to the electrical equipment in the locomotive to drive the vehicle. The carbon strip body 2 can be installed and fixed by setting the aluminum bracket body 1. By setting the insulating coating 102 on both sides of the aluminum profile 101, the contact between the aluminum profile 101 and the electric arc can be reduced, thereby suppressing the generation of large electric arcs and reducing the electrical wear of this device.

[0018] The top of the main structure 201 is provided with a slanted groove 202, and also includes a nylon arc extinguishing strip 3, which is fixedly installed inside the slanted groove 202.

[0019] By setting up the nylon arc-extinguishing strip 3, when a large electric arc is generated, the high temperature generated by the large electric arc will erode the nylon arc-extinguishing strip 3. The nylon arc-extinguishing strip 3 will quickly generate a large amount of gas, reduce the charged ions in the air to a certain density, suppress the large electric arc formed by the jumping of the carbon slide plate, thereby reducing the electrical wear of the device and improving its service life.

[0020] The aluminum profile 101 has a first cavity 104 and two sets of second cavities 105 inside. The first cavity 104 is located between the two sets of second cavities 105. Multiple sets of mounting posts 106 are fixedly installed in the first cavity 104. The bottom of the mounting post 106 has a mounting hole. A fixing screw 4 is threaded in the mounting hole. The fixing screw 4 is located below the aluminum bracket body 1.

[0021] By using the first cavity 104 and the second cavity 105 together, the strength of the aluminum profile 101 can be improved. By using the mounting post 106 together with the fixing screw 4, it is easy for the operator to connect and fix the device to the external pantograph.

[0022] Multiple sets of limiting strips 107 are provided between the card plates 103. The limiting strips 107 are integrally formed with the aluminum profile 101. Multiple sets of limiting grooves 203 are opened at the bottom of the carbon strip body 2. The limiting grooves 203 and the limiting strips 107 are interlocked with each other.

[0023] By setting multiple sets of limiting strips 107 in conjunction with limiting grooves 203, the area at the connection between the carbon strip body 2 and the aluminum bracket body 1 can be increased, and the friction at the connection can be increased, effectively preventing the carbon strip body 2 from tipping over when subjected to impact, extending the service life of the device and reducing the wear rate of the carbon slide plate.

[0024] In practical use, during the operation of the carbon sliding plate, due to the fixed height of the rigid contact wire, the height changes drastically between the rigid and flexible contact wires, resulting in a sharp increase in the carbon sliding plate's offline rate. The increased offline rate leads to more electric arcs between the contact wire and the carbon sliding plate, and the duration of the electric arcs increases. The high temperature generated by the electric arcs erodes the nylon arc-extinguishing strip 3. The nylon arc-extinguishing strip 3 rapidly generates a large amount of gas, reducing the density of charged ions in the air to a certain level, suppressing the large electric arcs formed by the jumping of the carbon sliding plate, thereby reducing the electrical wear of the device and improving its service life.
