Abstract

The utility model discloses a rail end junction safeguard device against the railroad malfunction. The channel pin junction string widely adopted at home now welds two pieces of chrome plating iron strings in 5mm diameter and a channel pin with both coned ends together, and the channel pin is knocked in the rail and the foreseen hole of a fishplate to ensure the good electric performance between the railroad rail joints. The problem is that the shedding or being stolen of the fishplate occurs for many times and in different places, in the said circumstances, the track was in a malfunction state, but the junction string was still in good condition and cannot send out the alarm, thus causing locomotive derailed and resulting serious casualties and material losses. The utility model uses U shaped clips to clamp on the fishplate and the rail to make the fishplate being a part of the rail electrical conductor; in case the fishplate is dismantled or stolen, the circuit shorts, then the alarm is given and the action is taken by the signal system, thereby the locomotive stops to avoid the occurrence of the traffic accident.

Description

A kind of rail termination continues device

Technical field

The utility model relates to a kind of railway signaling fault---safety guard, more particularly, relates to the continuous device of a kind of rail termination of rail.

Background technology

At present, in the extensive employing of China is the plug nail type bond wire, connect by two diameter 5mm galvanized iron wires and two terminal circle conical plug tack welding and to form, bond wire closely is attached to the top of fish plate when installing, iron wire two ends spirally-wound, with prevent that rail creeping from damaging or because of train by the time strenuous vibration come off.The rail end bond wire of rail also is rail bond, and it is to guarantee that excellent conductive performance is needed between the railway rail, is one of basic link in the signalling set of railroad train safety.Fish plate comes off problem having taken place repeatedly in the near future, or stolen, and this moment, track was under the broken rail state (faulty condition), and bond wire is still intact, and circuit is conducting still, and signal system is not reported to the police, derail takes place, and causes serious personal casualty and property damage.

Summary of the invention

The purpose of this utility model is to overcome the prior art deficiency, provides a kind of new construction rail termination to continue device, and it is reaction rail end coupled condition accurately and timely, particularly fish plate is destroyed on railroad track, under the stolen situation, in time report to the police, prevent that the serious accident of locomotive derailing from taking place.

The utility model is achieved by following technical proposals: make U type clamp with spring steel, be clamped on fish plate and the rail, fish plate, the rail correspondence position is drilled with the open-work that diameter is 9.8mm, U type clamp two ends respectively have a conical plug pin, make its dozen at fish plate during installation, in the preformed hole of rail, the bolt and nut tension is adopted on U type clamp both sides, prevent to become flexible, guarantee excellent conductive performance between railway rail, when fish plate comes off or stolen, make conduction state destroyed immediately, the signalling set action, report to the police, then by the locomotive automatic stop arrangement make locomotive stop by, avoid accident to take place.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1

Expression two one steel rails 1 among the figure, link together by bolt and nut 3 and fish plate 2, the plug pin 5 and the plug pin 11 of the continuous device 4 of rail termination are squeezed into respectively in fish plate 2 and the rail 1, the basic difference of the utility model and prior art is to do without bond wire the part of conductor, but fish plate is made the part of conductor.The utility model rail terminated line device comprises: U type clamp 6, both ends are welded with cylindrical-conical

steel plug pin

5,11, two plug pin parallel axes also at grade, and vertical with two limits of clamp 6, its axial location staggers again mutually, not on same axis; Clamp 6 usefulness spring steel are made, two limits bolt 7 of clamp 6, and nut 8 is strained and fixed; For preventing that it from getting loose, adopt packing ring 10 and spring washer 9.Produce fierce vibrations during locomotive operation, for preventing that

plug pin

5,11 from getting loose, except U type clamp 6 elastic reactions are arranged, the surface at the cone position of

plug pin

5,11 has and hangs soft metal such as tin, lead, copper, aluminium thin layer, plug pin is squeezed into rail and fish plate and is wanted firmly, can adopt during construction gas welding device give heat again riveting go into; Tin and lead can be to the inside face scattering and permeatings of rail 1, fish plate 2 borings, to improve the reliability of its conduction.Whether the railroad maintenance workman wants the routine test electric conductivity intact.

Embodiment 2

Convenient for Maintenance and Repair, the end of U type clamp 6 is not welded with

conical plug pin

5,11, can be on material, thickness, width with the corresponding to flat board of clamp, be stuck in the bottom of rail 1, contact with rail 1, fish plate 2 simultaneously.Good for guaranteeing contact, the corresponding site of rail 1 and fish plate 2 will be used grinder buffing, rust cleaning during installation, two ends of U-shaped clamp 6 are except will polishing, eliminating rust, it has the thin layer of hanging soft metal such as tin, lead, copper, aluminium with the surface, position that rail 1 contacts with fish plate 2, fixed support 12 is housed on the tie bolt 7, between support 12 and the rail 1 Nd-Fe-B magnetic pole magnet 13 is arranged,, prevent that it is loosening or come off in order to fastening U type clamp (6).
