Description
Technical field
The utility model relates to a kind of external division type cross switch, is applicable in the laying of a rail track and a station track switch.
Background technology
Slip switch both can make train cross another circuit by a circuit, can make train turn to another circuit by this circuit again.Slip switch is divided into double slip swich and single slip switches two classes.
Double slip swich can make train turn to along both sides, and it can open route to four direction, so can replace four groups of simple turnouts to use.As shown in Figure 1, be the double slip swich that generally uses at present, it is made up of diamond crossing railway frog and two groups of two railway switches that have four tip of a root rails respectively; Described diamond crossing railway frog is by two groups of end frogs 21 ', and two groups of obtuse frogs 31 ' are formed; And two groups of two railway switches with totally 8 tip of a root rails 11 ', 12 ', 13 ', 14 ', 15 ', 16 ', 17 ' and 18 ' in, tongue 12 ', 13 ', 16 ' and 17 ' is in the inside of the diamond crossing railway frog of track switch.
Single slip switches only can make train turn to along a side, and it can open route to three directions, so can replace three groups of simple turnouts to use.As shown in Figure 2, be the single slip switches that generally uses at present, it is made up of diamond crossing railway frog and two groups of common railway switches that have two tip of a root rails respectively; Described diamond crossing railway frog is by two groups of end frogs 21 ', and two groups of obtuse frogs 31 ' are formed; And two groups of common railway switches with totally 4 tip of a root rails 11 ', 12 ', 13 ' and 14 ' in, tongue 12 ' and 14 ' is in the inside of the diamond crossing railway frog of track switch.
As seen, in the above-mentioned double slip swich and single slip switches, always there is the tongue of half quantity to be in the inside of the diamond crossing railway frog of track switch.The slip switch of this form of structure, the total length of its length of switch rail, side line radius and track switch all is subjected to the number of diamond crossing railway frog, the restriction of railway frog angle [alpha] just: the railway frog number is littler, tongue is shorter, and the side line radius is also just little, thereby has limited the speed of passing through of train; Simultaneously, radius of lead curve is too small, and does not have superelevation, so gauge, level, direction all are difficult to keep; Play the lead curve terminal point from the point of switch and end, well-behaved, direction and height change are rapid, and gauge, horizontal lapse rate are bigger, train by the time to the horizontal and vertical impact force of track switch greater than common line.
In addition, because double slip swich adopts two groups of two railway switches, point tongue need be taked interlock, increased the action frequency of tongue, and electric affair turn-out track equipment circuit is loaded down with trivial details; Track switch from the railway switch to the railway frog between, union piece is more, and lax the inefficacy taken place easily; Rail is intensive simultaneously, switch tie is narrow at interval, gives to make firm by ramming and brings difficulty, causes the track hollow easily, and direction is bad, and growth encourage is creeped, and destroys gauge, the wearing and tearing of aggravation rail and part thereof, maintenance difficult.
Summary of the invention
The purpose of this utility model is to provide a kind of external division type cross switch, can abolish of the restriction of the railway frog angle of slip switch diamond crossing railway frog to length of switch rail, side line radius and total length of turnout, improve train by track switch speed and wheel to the bump of track switch, reduce the complexity that the turn-out track rod member connects; Adopt the railway switch of typical construction form, simplify the turn-out track formality.
For achieving the above object, the utility model provides a kind of external division type cross switch, and it comprises: diamond crossing railway frog, standard railway switch and stock rail;
Characteristics are that described diamond crossing railway frog includes four-way railway frog and obtuse frog; Be respectively arranged with 2 tip of a root rails on the described standard railway switch, and described all tongues all are arranged on the outside of diamond crossing railway frog;
Described external division type cross switch can be provided with 4 standard railway switches, forms outer fraction double slip swich;
Described external division type cross switch can be provided with 2 standard railway switches, forms outer fraction single slip switches;
Further, described external division type cross switch also comprises some check rails;
Described standard railway switch can be by single action form control track switch.
The external division type cross switch that the utility model provides, all tongues are arranged on the outside of diamond crossing railway frog, abolished the restriction of the railway frog angle of diamond crossing railway frog to the length of switch rail of slip switch, side line radius, total length of turnout equidimension, it has the following advantages:
1, because the tongue of track switch is arranged on the outside of diamond crossing railway frog, under the identical situation of the railway frog angle of diamond crossing railway frog, can improve the sweep of slip switch greatly, can allow train to pass through track switch, promote operating efficiency with fast speeds.
2, the sweep owing to slip switch strengthens, thereby reduces laterally to reach the impact force that vertically is subjected to, and reduces the degree of wear of tongue, significantly reduces maintenance load.
3, because increase is provided with check rail, can improve driving condition, guarantee the traffic safety of train.
4, external division type cross switch can be got in touch laying on the branch-cut bridge between parallel circuit, do not need to insert the wire spacing of short rail with maintenance track switch between track switch, thereby the laying length of external division type cross switch is unrestricted.
5, owing to use the standard railway switch in the utility model, the track switch switching control system is identical with existing common single turnout, and circuit structure is simply finalized the design, and conveniently carries out conversion and control.
6, according to the small size external division type cross switch of the utility model design, floor space is little, and sweep is big, can use the zone in narrow terrain such as industrial enterprise; And according to the large size external division type cross switch of the utility model design, sweep is big, allows train to pass through at a high speed, is suitable for using as the acclerating road switch of novel railway.
