Description

Technical Field

[0001] This utility model belongs to the field of rail transit technology and relates to a busbar contact wire wear continuous compensation device. Background Technology

[0002] Rail transit refers to a type of transportation vehicle or system that requires operating vehicles to run on specific tracks. It is a general term for rapid, high-capacity public transportation, typically powered by electricity and operating via wheel-rail systems. Rail transit includes busbars, at the bottom of which are contact wires. After a period of use, the contact wires experience wear and tear, requiring compensation at the worn areas.

[0003] Existing compensation devices for busbar contact wire wear, such as the busbar contact wire wear compensation structure disclosed in Chinese patent literature [Patent No.: 202321367428.0; Application Publication No.: CN219874238U], involve contact wires arranged along the opening at the bottom of the busbar. The wear compensation structure includes a pair of guide plates fixed to both sides of the busbar. The guide plates are electrically connected to the busbar, and the bottom surface of the guide plates is located below the busbar, flush with the bottom of the unworn contact wire.

[0004] This type of wear compensation structure uses guide plates fixed on both sides of the wear area of ​​the contact wire. When the pantograph moves across this area, it contacts the guide plates, which replace the contact wire in that area, thus compensating for the wear. However, the guide plates in this structure are relatively short, only compensating for short sections of the wear area. In real-world environments, contact wires experience long-distance wear, and this type of wear compensation structure is insufficient in length to fully compensate for the worn contact wire, leading to unstable and unreliable power supply from the busbar. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a continuous compensation device for busbar contact line wear, which solves the technical problem of how to compensate for long-distance wear of contact lines.

[0006] The objective of this utility model can be achieved through the following technical solution: a busbar contact wire wear continuous compensation device, wherein the contact wire is fixedly connected to the bottom of the busbar, characterized in that the compensation device includes several pairs of wire clamps symmetrically fixedly connected to both sides of the busbar, one end of each wire clamp has an inner clearance opening on its inner side, and the other end of each wire clamp has an outer clearance opening on its outer side, two adjacent wire clamps are inserted into each other through the inner clearance opening and the outer clearance opening and fixedly connected by fasteners, and a wire is fixedly connected to the bottom of each wire clamp, the bottom of the wire being flush with the bottom of the unworn contact wire.

[0007] Adjacent clamps are interlocked via inner and outer clearance slots and secured with fasteners such as bolts, allowing multiple clamps to be connected as a single unit. These clamps are arranged along the length of the busbar, increasing the overall length of the compensation device and enabling it to compensate for long-distance wear on the contact wire. Depending on the length of the worn contact wire, different numbers of clamps can be selected for connection, improving the versatility of this compensation device.

[0008] In the aforementioned busbar contact wire wear continuous compensation device, the clamp includes an outer clamp plate and an inner clamp plate. One end of the outer clamp plate protrudes outward from one end of the inner clamp plate along the length direction of the busbar, forming an inner clearance opening on the inner side of one end of the clamp. The other end of the outer clamp plate is recessed inward from the other end of the inner clamp plate along the length direction of the busbar, forming an outer clearance opening on the outer side of the other end of the clamp. By staggering the outer and inner clamp plates along the length direction of the busbar, inner and outer clearance openings are formed, facilitating the connection of multiple clamps and ensuring a high degree of secure connection.

[0009] In the aforementioned busbar contact wire wear continuous compensation device, both the outer clamping plate and the inner clamping plate are elongated strips of the same length. Fasteners are inserted into the outer and inner clamping plates to secure them together. This structure, by offsetting the outer and inner clamping plates along the length of the busbar, creates inner and outer clearance openings.

[0010] In the aforementioned continuous compensation device for busbar contact wire wear, several pairs of supports are spaced apart on the busbar. The wire clamps located on both sides of the busbar are fixedly connected to each other through the supports, and the supports are attached to the inner sidewall of the other end of the inner clamping plate. The supports securely connect the wire clamps to both sides of the busbar, resulting in a simple structure. The supports are attached to the inner sidewall of the other end of the inner clamping plate, and fasteners such as bolts pass through one end of the outer clamping plate, the other end of the inner clamping plate of the adjacent wire clamp, and the supports, thus securing the compensation device to the busbar. The connection position is reasonable and the strength is high.

[0011] In the aforementioned busbar contact wire wear continuous compensation device, the outer end face of the outermost clamp at all the clamps is planar. This structure makes the compensation device flat.

[0012] In the above-mentioned busbar contact wire wear continuous compensation device, there is a gap between the wire clamp and the busbar.

[0013] Compared with the prior art, the busbar contact wire wear continuous compensation device provided by this utility model has the following advantages:

[0014] 1. This compensation device is made up of multiple wire clamps connected together, which increases the overall length of the compensation device. This allows the compensation device to compensate for long-distance wear of the contact wire. In addition, different numbers of wire clamps can be selected to connect according to the length of the wear of the contact wire, which improves the versatility of this compensation device.

[0015] 2. This compensation device forms inner and outer clearance openings by staggering the outer and inner clamps along the length of the busbar, making it convenient to connect multiple clamps and ensuring a high degree of security in the connection. Attached Figure Description

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 , Figure 3 , Figure 4 As shown, the contact wire 1 is fixed to the bottom of the busbar 2. The continuous wear compensation device for the contact wire 1 of the busbar 2 includes a clamp 3, a wire 4 and a bracket 5.

[0023] In this embodiment, there are four pairs of wire clamps 3, which are symmetrically fixed on both sides of the busbar 2. There are three pairs of brackets 5, and the wire clamps 3 located on both sides of the busbar 2 are fixed together by the brackets 5. In actual production, the number of wire clamps 3 can be two or six pairs, and the number of brackets 5 can be one or five pairs.

[0024] like Figure 2As shown, the inner side of one end of the wire clamp 3 has an inner clearance opening 31, and the outer side of the other end of the wire clamp 3 has an outer clearance opening 32. Specifically, the wire clamp 3 includes an outer clamp plate 33 and an inner clamp plate 34. Both the outer clamp plate 33 and the inner clamp plate 34 are elongated and have the same length. One end of the outer clamp plate 33 protrudes outward along the length direction of the busbar 2 and is disposed outside one end of the inner clamp plate 34, forming an inner clearance opening 31 on the inner side of one end of the wire clamp 3. The other end of the outer clamp plate 33 is recessed inward along the length direction of the busbar 2 and is disposed inside the other end of the inner clamp plate 34, forming an outer clearance opening 32 on the outer side of the other end of the wire clamp 3. The outer clamp plate 33 and the inner clamp plate 34 are fixed together by fasteners such as bolts inserted into them to form the wire clamp 3.

[0025] Two adjacent wire clamps 3 are interlocked through inner clearance openings 31 and outer clearance openings 32 and fixed together by fasteners such as bolts, so that multiple wire clamps 3 are connected as a whole. The bracket 5 is attached to the inner side wall of the other end of the inner clamp plate 34. There is a gap between the wire clamp 3 and the busbar 2. The outer end face of the outermost wire clamp 3 is flat. A wire 4 is fixed to the bottom of the wire clamp 3, and the bottom of the wire 4 is flush with the bottom of the unworn contact wire 1.

[0026] During installation, select an appropriate number of clamps 3 according to the wear condition of the contact wire 1. Place the bracket 5 against the inner wall of the other end of the inner clamp plate 34. Use fasteners such as bolts to pass through one end of the outer clamp plate 33, the other end of the inner clamp plate 34 of the adjacent clamp 3, and the bracket 5 to fix the clamps 3 to both sides of the busbar 2. One end of the outer clamp plate 33 and the other end of the inner clamp plate 34 of the adjacent clamp 3 both have strip holes arranged in the vertical direction. Fasteners such as bolts can be inserted into the strip holes to change the height of the clamps 3, ensuring that the bottom of the conductor 4 is flush with the bottom of the unworn contact wire 1.
