Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit vehicles, and more specifically, relates to a rail transit vehicle current collector system. Background Art

[0002] The current collector is a key component of the bogie of a rail transit vehicle. It connects the current collector to the power rail and collects current to provide power to the vehicle's drive, lighting, and auxiliary systems. The current collector system primarily includes a power shoe and a grounding shoe, as well as matching cables and clamps. The current collector is mounted on the vehicle's bogie and is mated to the track contact rail via a carbon slider. The carbon slider and the contact rail must maintain contact at all times during vehicle operation, which results in the generation of wear powder, a noisy environment, and contamination of the track posts. Existing rail vehicles are not equipped with dust removal and purification systems, and wear powder from the current collector will drift onto the track posts, causing environmental pollution.

[0003] The prior art includes a technology entitled "Current Collector for Rail Vehicles" and having a publication (announcement) number of "CN114302822B." This technology is used for current collectors (STA) for rail vehicles used in cross-border transportation. A current collector (STA) carrier (TR) places two sliders (SL1, SL2) in conductive contact with a slide feeder on top of the vehicle. The two sliders (SL1, SL2) have a first length (L1). Each slider (SL1, SL2) has a slider extension (SLV11, SLV12, SLV21, SLV22) at each end (SLE11, SLE12, SLE21, SLE22). The slider extensions (SLV11, SLV12, SLV21, SLV22) are rotatably supported and connected to the corresponding ends (SLE11, SLE12, SLE21, SLE22) of the sliders (SL1, SL2). In the first position (POS1), the slide extension (SLV11, SLV12, SLV21, SLV22) flips over to close the slides (SL1, SL2) and the slide extension (SLV11, SLV12, SLV21, SLV22), and the combined total length corresponds to the first length (L1) of the slides (SL1, SL2). In the second position (POS2), the slide extension (SLV11, SLV12, SLV21, SLV2) flips over to open the slides (SL1, SL2) and the slide extension (SLV11, SLV12, SLV21, SLV22), and the combined total length corresponds to a second length (L2) that is greater than the first length (L1).

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

During rail transit vehicle operation, the current collector and grounding shoes 1 maintain constant contact with the contact rail 7. This is when the dust removal system activates. A collection hood 2 is installed at the carbon slider 11 of the current collector and grounding shoe 1. This hood 2 surrounds the contact area between the carbon slider 11 and the contact rail 7 from its outer ring. Dust generated by the wear between the carbon slider 11 and the contact rail 7 does not escape into the air but is instead trapped and collected by the dust removal system's collection hood 2. Under the negative pressure of the air blower 6, the dust is collected through the air duct 3 into the dust collector 5 and then into the dust box 4, ensuring reliable dust collection. The dust box 4 can be cleaned regularly. The beneficial effects of this structure are as follows: 1. It integrates the rail vehicle current collector with the dust removal system. 2. It directly collects dust through the onboard negative pressure connection, making it convenient and simple. Active negative pressure collection increases efficiency. 3. The collection hood is integrated into the current collector and grounding shoe, moving synchronously with them, avoiding the problem of poor dust collection due to asynchronous movement. 4. The air machine makes the dust collection more efficient. The rail transit vehicle current collector system described in the utility model has a simple structure and can collect the wear powder generated during the operation of the rail transit vehicle through negative pressure, preventing the wear powder from floating on the track columns, thereby optimizing the environment.

[0023] The dust collector 5 is connected to an air blower 6. In the above structure, the dust collector is fixedly mounted on a rail transit vehicle 8, and the air blower 6 is connected to the vehicle control unit. During the operation of the rail transit vehicle, as soon as the vehicle starts, the air blower 6 is controlled to start and collect dust.

[0024] The collecting hood 2 is connected to the dust collector 5 through the air pipe 3. In the above structure, the collecting hood prevents the dust from being scattered outward, and collects the dust through the negative pressure generated by the air machine.

[0025] The current collecting shoe and grounding shoe 1 includes a left current collecting shoe and a right grounding shoe. The carbon slider 11 of the left current collecting shoe and grounding shoe contacts the contact rail 7 on the left, and the carbon slider 11 of the right current collecting shoe and grounding shoe contacts the contact rail 7 on the right. The left contact rail 7 is located on the left side of the track 10, and the right contact rail 7 is located on the right side of the track 10. The outer ring of the left current collecting shoe and grounding shoe is fitted with a collection cover 2, and the outer ring of the right current collecting shoe and grounding shoe is fitted with a collection cover 2.

Each collection hood is fixedly connected to the outer ring of the corresponding carbon slider 11 to achieve a reliable connection.

[0027] The rail transit vehicle current collector system described in the present invention is structurally configured to include a component with a negative pressure collection function on the rail transit vehicle's current collector. An air line 3 connects the negative pressure collection component's collection hood 2 to an onboard dust collector (dust collector) 5 and an onboard air blower (air blower) 6, conveniently and reliably resolving the problem of wear and dust pollution. During rail transit vehicle operation, the current collecting shoe and grounding shoe 1 maintain constant contact with the contact rail 7. At this point, the dust removal system activates, and a collection hood is positioned over the carbon slider 11 of the current collecting shoe and grounding shoe 1.
