Abstract
The utility model relates to urban rail transit and is aimed at providing an alloy steel combined frog track backflow connecting device. The track backflow connecting device comprises screw nuts, plug pins, cables, wire noses, a wing rail, and a fork rail. The wing rail and the fork rail are used for communicating a frog. Connecting holes are drilled on the wing rail and the fork rail of the frog. The plug pins are mounted in the connecting holes. The wire noses are mounted on the two ends of the cable. The plug pins and the wire noses are fixedly connected by using the screw nuts. The alloy steel combined frog track backflow connecting device has simple manufacturing technique and reasonable design and resolves a problem of backflow of a high-performance alloy steel combined frog used in urban rail transit. Frogs with high strength, good wear-resistant performance, and long service lives can be selected for urban rail transit so as to increase the using efficiency of the frogs and traveling security and save lots of steel and maintenance cost, according with the requirement of energy saving and emission reduction.
Description
Technical field
The utility model is about urban track traffic, particularly a kind of steel alloy assembled frog track backflow jockey.
Background technology
Railway frog is to make wheel by the path crossing on the same level equipment of one rail by another strand rail, is the important component part of urban track traffic track switch.The railway frog that urban track traffic is at present used mainly is high manganese steel frog.Because high manganese steel frog is that monoblock cast forms, and has various casting flaws, influences its useful life.And steel alloy assembled frog excellent performance on common and high-speed railway, progressively replaces potassium steel casting railway frog.Therefore, the steel alloy assembled frog is introduced urban track traffic, reduce and safeguard the useful life that can improve railway frog, increase the benefit.
Different with the common railway traffic, the direct-current traction power supply mode is adopted in urban track traffic, and its path is traction substation positive pole～contact line (conductor rail)～vehicle (load)～track～negative pole cable～traction substation negative pole.This mode be rail as current return circuit, directly be connected to the traction substation negative pole by the negative pole cable.Railway frog directly is connected on the circuit rail, and as the part of current return circuit, it is big by electric current, and for avoiding must guaranteeing that because electric current produces heat (especially electric arc) rail of burning railway frog has the favorable conductive effect, it is unobstructed to reflux.Solid manganese steel frog is overall structure, and its electric conductivity is good, and the steel alloy assembled frog is the split mounting type railway frog, is made up of with parts such as rail, interval iron and bolts wing rail, heart rail, fork, and it can not guarantee reliable electric conductivity each other.
Therefore, provide a kind of novel alloy steel assembled frog track backflow jockey that can overcome above-mentioned deficiency, seem very necessary for the useful life and the traffic safety that improve railway frog in the urban track traffic.
The utility model content
Main purpose of the present utility model is to overcome deficiency of the prior art, and a kind of track backflow jockey that solves electric conductivity between each parts of steel alloy assembled frog is provided.For solving the problems of the technologies described above, solution of the present utility model is:
A kind of steel alloy assembled frog track backflow jockey is provided, the wing rail and the fork that are used for the connection railway frog are followed rail, the wing rail of railway frog and fork are drilled with connecting hole with on the rail, described track backflow jockey comprises nut, plug pin, cable and line nose, plug pin is installed in the connecting hole, wired nose is installed at the cable two ends, and utilizes the fixedly connected plug pin of nut and line nose.
As further improvement, described plug pin adopts expansion type to be electrically connected plug pin.
As further improvement, the wing rail of described railway frog homonymy and fork are with having at least a cable to connect between the rail.
Compared with prior art, the beneficial effects of the utility model are:
Manufacturing process is simple, reasonable in design, and solved the reflux problem of high performance steel alloy assembled frog in city rail uses, make urban track traffic can select intensity height, anti-wear performance is good, the life-span is longer railway frog for use, thereby improve service efficiency and the traffic safety of railway frog, save great deal of steel and maintenance cost, meet the energy-saving and emission-reduction requirement of country.
Description of drawings
Fig. 1 is scheme of installation of the present utility model.
Fig. 2 is partial top view of the present utility model.
Fig. 3 is the cross-sectional view at A-A place among Fig. 2.
Reference numeral among the figure is: 1 fork is with rail; 2 wing rails; 3 nuts; 4 plug pins; 5 line noses; 6 cables.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1 to Figure 3, a kind of steel alloy assembled frog track backflow jockey comprises nut 3, plug pin 4, cable 6 and line nose 5, is used for being communicated with the wing rail 2 of railway frog and pitching with rail 1.Wing rail 2 and the fork of railway frog are drilled with connecting hole with on the rail 1, and plug pin 4 is installed in the connecting hole, and wired nose 5 is installed at cable 6 two ends, and utilizes nut 3 fixedly connected plug pin 4 and line noses 5, make the wing rail 2 of railway frog homonymy and pitch to follow to have at least a cable 6 to connect between the rail 1.Plug pin 4 is adopted as expansion type and is electrically connected plug pin 4.
The utility model does not change the primary structure of railway frog, and railway frog basic configuration structure is consistent with the common railway railway frog, only increases connecting hole, and basic identical with existing railway frog manufacturing process, the railway frog versatility is good.At first at rail wing 2 heel end positions and fork bore connecting hole with the corresponding site of rail 1, as shown in Figure 2, at connecting hole expansion type is installed and is electrically connected plug pin 4, guarantee that plug pin 4 reliably is connected with rail.Then at cable 6 two ends hookup wire noses 5, use plug pin 4, nut 3 to be connected as a single entity with rail 1 wing rail 2 forks adjacent with homonymy with one or more cable 6, guarantee that rail wing 2 and fork are unimpeded with refluxing between the rail 1, thereby guarantee the electric conductivity of railway frog integral body, satisfy the city rail traffic route instructions for use.Such design processing is simple, and material is saved, and can satisfy the railway frog job requirement.
It is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
