Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further details of
Explanation.
As shown in Figures 1 to 5, this trapezoidal track switch, including straight rail 1, bend road, tongue, the three jag hearts 7, wherein, bend
Road is the suite track being arranged side by side, and a suite track is respectively positioned on the same side of straight rail 1, and a suite track uniform intervals sets
Put.Being the track switch combined by a common wire and some shunting necks, common wire is straight rail, and shunting neck is bend
Road, its Main Function is the function realizing multiply modified line in limited space.
Straight rail 1 arrival end the first bend road realizes turn-out track by a pair tongue and is connected, if Fig. 1 is by straight rail porch
A pair tongue I 6, a pair tongue forms first railway switch, can be bent from straight rail modified line to first by train by a pair tongue
On track 2.
It is bent that bend road below, first bend road 2 is followed successively by the second bend road the 4, the 4th, bend road the 3, the 3rd being arranged side by side
Track 5；The quantity in bend road can be arranged as required to, as in figure 2 it is shown, be arranged side by side ten suite tracks.
First each bend road below, bend road 2 all realizes turning with straight rail by three jag hearts 7 and a tongue
Rut is connected；One three jag heart and a tongue form a railway switch, by a tongue and corresponding three jag excess of the heart
Now train is deformed to corresponding bend road from straight rail；Tongue II 8 He such as the second bend road 3 corresponding in Fig. 1
One three jag is formed centrally a railway switch in corresponding second bend road.
The tongue in each bend road below, the first bend road 2 is connected with straight rail the same side single track, each three jag hearts
It is arranged side by side and is connected with straight rail opposite side single track.
The radius of curvature in bend road is 22-28m, preferably 25m.The adjacent bent track space of one suite track is 5-
6m, preferably 5.5m.The fork of docking can be formed centrally protection.
The side of tongue is provided with arc groove, improves tongue elasticity bendable performance, thus improves job stability.Under tongue
Side is provided with turn-out track framework, and turn-out track framework includes that superstructure and understructure, superstructure material are NM400 steel plate, and lower floor ties
Structure material is that Q345 steel plate, superstructure and understructure are by the company of being formed in the formation overall structure that is weldingly connected, turn-out track framework
Continuous slider bed table top, provides sufficiently supporting to tongue.Extend track switch service life, and low cost.
Three jag pericardiums include Q345 steel plate thick for 120mm and the NM400 steel plate of 60mm above thickness being positioned at lower section,
The entirety of the height 180mm that both welding are assembled, then in CNC milling machine, milling forms.Work surface tensile strength
Reaching 1200MPa, hardness reaches 360～440HBW, it is ensured that track switch is longer than the life-span of main track for service life.
The three jag hearts use wheel rim to hold the design of groove；Fork heart entrance in the range of the first theoretical point, groove depth by-
47mm transits to-21mm；After first theoretical point, groove depth is returned to-47mm by-21mm gradual change；The groove bottom of crossing can be hung down
Allotment support wheel rim.Owing to the space of this position is limited to, it is impossible to separate two sections of grooves, therefore use wheel rim to hold the design side of groove
Formula；This kind of mode achieves in finite spatial extent, is transitioned into the probability of both direction.
The inner side in straight rail and bend road is all equipped with guard rail groove, mills out guard rail groove by rail all over the face and replaces installation to protect
Rail, guard rail groove is U-type groove, saves separately installed guard rail, and Stability Analysis of Structures is reliable, and under limited spatial environments limits, real
Show the form of guard rail protection；Decrease installation procedure, simplify part category, reduce cost, improve efficiency.
Contact surface between tongue and turn-out track framework is processed to wedge shape, with wedge buckle ferrum, tongue is fixed on heel end portions
Position, is embedded into when tongue is pulled, and when maintenance activity for ease of maintenaince.
The point of switch arranges Anti-tripping structure, prevents tongue from vertical displacement occur；Heel of switch rail sets stop, prevents tongue from going out
Existing length travel.
Turn-out track framework is provided with osculum 9, and the diameter of osculum is more than being positioned at the width of tongue, draining directly over osculum
Drain pipe, simple in construction it is connected to, it is ensured that there is good drainage effect below hole.
Owing to trapezoidal switch structure is compact, except entrance uses both sides tongue, centre is unilateral tongue, when straight stock is opened,
Tongue need to take into account the function of guard rail.Corresponding tongue flange of rail design top ferrum, had both simplified top iron construction, and had enhanced straight stock simultaneously and cross car
Time anti-side knock ability.Corresponding switch blade Position Design has adjustable top ferrum, and can adjust tongue accurately protects well width.
This trapezoidal track switch realizes the function of multiply modified line in limited space, and it can branch to some in short distance
On track, save arrangement space, it is simple to arrange, land use rate is greatly improved, reduce engineering cost.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way
Restriction, as long as have employed the design of the present invention and the improvement of various unsubstantialities that technical scheme is carried out, or the most improved will
Design and the technical scheme of the present invention directly apply to other occasion, all within protection scope of the present invention.
