Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a rail transit motor vehicle cable. Background Art

[0002] Rail transit refers to a type of transportation tool or transportation system in which operating vehicles need to travel on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, rail transit has shown more and more types, not only covering long-distance land transportation, but also widely used in medium and short-distance urban public transportation. Common rail transit includes traditional railways, subways, light rails and trams, and new rail transit includes magnetic levitation rail systems, monorail systems and automatic passenger rapid transit systems. The existing rail transit cable structure is too simple, resulting in insufficient functions and insufficient protection of the inner wall cable. The internal cables are not easy to repair and replace, and there is no partition structure between the cables. In the process of extracting the internal cables, the outer skin of the adjacent cables will be damaged due to friction. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a rail transit motor vehicle cable.

[0004] A rail transit motor vehicle cable proposed by the present invention comprises a first rubber layer, wherein the inner wall of the first rubber layer is provided with a plurality of groups of protrusions, wherein the protrusions are arc-shaped and bent to one side, wherein the side with a larger arc among the two sides of the protrusions is an outer arc wall, and the side with a smaller arc is an inner arc wall, wherein the protrusions are provided with a plurality of groups, wherein the top ends of the protrusions are bent toward the middle of the outer arc walls of the adjacent protrusions, and the plurality of groups of the protrusions are distributed with the midpoint of the first rubber layer as the center;

[0005] The top end of the protrusion has a contact portion with the outer arc wall bent toward the adjacent protrusion, and the contact portion separates the adjacent protrusion outer arc wall into an upper outer arc wall and a lower outer arc wall;

[0006] The space formed by the upper outer arc wall of each group of protrusions is a main cavity, which is used to position the main cable;

[0007] The space formed by the inner arc wall of each group of protrusions, the lower outer arc wall of the protrusion bent toward the adjacent protrusion and the inner wall of the corresponding first rubber layer is an attached cavity for positioning the auxiliary cable.

[0008] Preferably, the top of each group of protrusions is rounded, the contact portion of each group of protrusions is provided with a groove, and the rounded corner of the top of the protrusion matches the groove of the protrusion bent toward the adjacent protrusion.

[0009] Preferably, a second rubber layer is sheathed on the exterior of the first rubber layer.

[0010] Preferably, a plurality of groups of connecting members are provided between the first rubber layer and the second rubber layer, and the plurality of groups of connecting members are distributed around the midpoint of the first rubber layer.

[0011] Preferably, each group of connecting members is cylindrical.

[0013] Preferably, the outer wall of the metal armor layer is provided with an outer protective layer.

[0014] Preferably, the protrusions are provided in six groups.

[0015] In the present invention, a rail transit motor vehicle cable is proposed, in which the first rubber layer and multiple groups of protrusions are integrally formed, which is convenient for production. Through the bending of the protrusions, the top of the protrusions and the lower outer arc wall of the adjacent protrusions and the corresponding first rubber layer form a triangular cavity for positioning each auxiliary cable.
