Examples

The embodiment provides a metal air flue for carbon slide board, includes: a metal tube 31; and metal joints 32 disposed at both ends of the metal pipe 31.

As shown in fig. 2, at least one cutting mark 311 is provided on at least a part of the outer diameter of the metal pipe 31 in the longitudinal direction of the metal pipe 31, and the cutting mark 311 is provided in a spiral shape. Because the cutting mark is the heliciform setting for in specific region, the cutting mark can full length cover, after buckling the tubular metal resonator, can all take place gas leakage in arbitrary region, thereby the tubular metal resonator that solves among the prior art that the cutting mark can be fine is along radially setting up, and the tubular metal resonator that is located between two adjacent cutting marks can't take place the defect of damaged gas leakage.

Specifically, in the present embodiment, the number of the cutting marks arranged in the spiral shape is one. As a modification, a plurality of pieces may be provided, the plurality of cut lines being arranged in parallel with each other. Through setting up many cutting marks that are parallel to each other for after the tubular metal resonator takes place to buckle, cutting mark self takes place the probability greatly increased of gas leakage, thereby makes the pantograph break away from the contact net fast.

In this embodiment, the spiral cutting mark may be only disposed in a small area of the metal pipe, and the specific area may be selected according to a portion of the metal pipe where air leakage easily occurs. In a preferred embodiment, in the present embodiment, the end portions of the cutting lines 311 are provided at both ends of the metal pipe 31. Through such a setting mode, the whole air flue can accomplish not to have the protection blind area.

In a modified embodiment, the cutting mark itself may be present in the metal pipe in a spiral shape or in a mixed shape perpendicular to the axis of the metal pipe. For example, a cutting mark may be provided at both ends of the metal pipe in a spiral shape, and then a cutting mark may be provided at a middle portion of the metal pipe in a direction perpendicular to the axis of the metal pipe.

In the metal gas duct for a carbon sliding plate provided in this embodiment, the ratio of the pitch of the cutting mark 311 to the length of the metal pipe 31 is (1-3): 10. specifically, the ratio may be 1:10, or 2:10, and the specific value may be adjusted according to the actual working condition, and is not limited in this embodiment.

In the metal gas duct for a carbon sliding plate provided in this embodiment, the depth of the cutting mark 311 is 1/4 to 1/2 of the wall thickness of the metal pipe 31. Through foretell size setting mode for cutting mark 311 self has certain intensity, can also ensure simultaneously that after tubular metal resonator 31 self takes place to buckle, cutting mark 311 self can in time take place to damage, thereby makes the pantograph break away from the contact net fast.

In this embodiment, the air duct 3 itself is provided in the form of a housing chamber. The air channel 3 can be arranged in the carbon strip 1, the metal bracket 2 and between the carbon strip 1 and the metal bracket 2, for example, the carbon strip and the metal bracket respectively contain half of the metal air channel.

As a preferred embodiment, the gas passages 3 themselves are provided in the carbon strip 1, as shown in fig. 1. The carbon strip 1 itself is easier to perform a machining operation than the metal bracket 2, thereby reducing the machining difficulty.

In this embodiment, as shown in fig. 2, the metal joint 32 of the metal duct for the carbon slide plate is connected to the metal bracket 2 by a screw joint.

In this embodiment, the metal bracket 2 is an aluminum bracket, and the metal tube 31 of the metal air passage for the carbon sliding plate is a copper tube. Alternatively, the metal bracket and the metal tube may be made of other materials, such as metal, iron, alloy, etc. Or non-metallic materials such as ceramic materials. The specific material can be adjusted according to actual conditions.

In the carbon slide that this embodiment provided, carbon strip 1 with connect as an organic wholely through gluing between the metal bracket 2. The material of the adhesive itself is not limited too much in this embodiment, as long as the connection between the carbon strip and the metal bracket 2 can be achieved.

As a variant, other connection means may be used between the carbon strip and the metal carrier, such as inserting the carbon strip 1 into the metal carrier 2 by interference fit.
