Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] see Figure 2-4 , a rail gauge pull rod for rail transit, comprising a portable connector 5, the inner wall of the portable connector 5 is fixedly glued with an insulating plastic 6, the material of the insulating plastic 6 is ABS plastic, and the length of the insulating plastic 6 is the same as that of the portable connector 5 The length of the inner cavity is consistent, and the inner cavity of the portable connector 5 is located on both sides of the...

The invention relates to the technical field of rail transit, and discloses a rail gauge tie rod for rail transit, comprising a portable connecting piece, the inner wall of the portable connecting piece is fixed and glued with insulating plastic, and the inner cavity of the portable connecting piece is located on the inner wall of the insulating plastic. Fixed permanent magnets are fixedly installed on both sides, a magnetic pull rod is movably installed inside the insulating plastic, and a pull rod head is welded on one side of the magnetic pull rod located in the inner cavity of the portable connector. The rail gauge tie rod for rail transit is provided with two permanent magnets opposite to the same pole between the portable connector and the magnetic tie rod, so that the two mutually repelling permanent magnets are not in contact with each other and can resist the pulling force of the lateral separation of the track, so that It can prevent the contact between the magnetic pull rod and the portable connector to achieve the effect of insulation, and compared with the traditional horizontal pull rod, which directly exerts the pulling force on the plastic, causing the internal plastic to be easily damaged, this magnetic non-contact method is more conducive to Protects the stability of the internal structure.
Description
technical field [0001] The invention relates to the technical field of rail traffic, in particular to a gauge tie rod for rail traffic. Background technique [0002] The gauge tie rod is a connecting piece for railways, its function is to connect two rails through the traction force of the rod to improve the lateral stability of the rail. [0003] see figure 1 , the existing gauge tie rod structure includes: metal shell 1, plastic lining 2, insulating crosspiece 3 and transverse tie rod 4, in the process of work, due to the insulation treatment in the middle of the railway with the circuit, it is necessary to insulate the metal The plastic lining 2 is injected between the connectors to ensure the insulation effect, but because the transverse tie rod 4 directly acts on the plastic lining 2 when the force is applied, the plastic lining 2 becomes a vulnerable part of the gauge tie rod, so it needs to be frequently The metal shell 1 is replaced to prevent short circuits; in ad...
