Description

Technical Field

[0001] The invention relates to the technical field of train power collection, in particular to a combined current collecting shoe slide plate for urban rail vehicles. Background Art

[0002] The collector shoe skateboard directly contacts the contact network and draws electricity from the contact network, so that the electric energy is transmitted 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. 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 lose corners, resulting in abnormal ignition. At the same time, the conductive rail is attached with ice, making it impossible for the skateboard to obtain electricity from the conductive rail, which in turn causes the train to lose its running power, thereby causing a series of unsafe accidents such as train suspension. At the same time, during the long deicing process, it is easy to cause ice to accumulate on the surface of the deicing unit, greatly reducing the deicing effect and increasing resistance. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the collector shoe skateboard is currently prone to icing, resulting in greater wear. At the same time, during a long deicing process, it is easy to cause ice accumulation on the surface of the deicing unit, greatly reducing the deicing effect and increasing resistance.

[0023] In order to cooperate with the lateral flow guidance and automatic control, a horizontal guide port 36 is opened on the side wall of the assembly bracket 1, and a bottom guide groove 37 cooperating with the horizontal guide port 36 is opened on the lower surface of the lubricating component 2. Semi-exposed driving impellers 4 are movably installed on the inner walls on both sides of the bottom guide groove 37, and a lateral separation mechanism controlled by the semi-exposed driving impeller 4 is movably installed inside the deicing groove 35.

[0025] The semi-exposed driving impeller 4 is located on one side of the bottom guide groove 37 and protrudes toward the inside of the bottom guide groove 37. When the train is running at high speed, the semi-exposed driving impeller 4 is driven by introducing wind pressure into the bottom guide groove 37, thereby controlling the rotation of the semi-exposed driving impeller 4.

[0026] In order to cooperate with driving and control, the semi-exposed driving impeller 4 includes a driving disk 42 with lateral driving blades 41 on the outside, an upper guide blade 43 fixed to the upper end of the driving disk 42, an upper assembly shaft 44 fixed to the upper end of the driving disk 42 and an eccentric wheel shaft 45 fixed to one side of the lower end of the driving disk 42.

[0027] In order to cooperate with the internal control, an internal control groove 5 is opened inside the deicing unit 32, and the internal control groove 5 is connected with the deicing groove 35 and the bottom assembly groove.

[0038] Taking advantage of the copper-based powder metallurgy material / copper alloy's advantages of both electrical conductivity and mechanical properties, the structure is combined with the carbon slide to break the frost attached to the surface of the conductive rail, protecting the carbon slide without damaging the conductive rail. The unique copper block chute design improves the ice-breaking efficiency of the slide while smoothly discharging the water formed by the melted ice due to frictional heat, preventing short circuit problems caused by residual water not being removed in time.
