Abstract
The invention relates to a monorail traffic straight and curved mobile turnout in order to overcome the problems that the traditional turnout has a large occupied area and high cost. The monorail traffic straight and curved mobile turnout comprises a straight track and a side track, wherein the straight track and the side track respectively comprise straight and curved turnout track beams and walking surfaces to form a walking track of vehicles, and the turnout track beams are arranged on a trolley; the trolley is put on the walking track and a crank arm is driven by a driving device to move in a guide groove, and the guide groove is formed in the straight turnout track beam to drive the straight track and the side track to rotate together to realize the connection of the other route; meanwhile, a crank device is arranged on a motor speed reducer fixedly arranged on the ground and the motor speed reducer drives a crank to rotate, and a roller wheel on the crank device is positioned in the guide groove and can slide; the guide groove and the turnout track beam connected with the guide groove are shifted to move. Compared with the turnout making linear movement, the designed structure is more compact, the land resources are saved, and great flexibility for route selection of route design is brought.
Description
Technical field
The invention belongs to the improvement in track traffic facility technology field, particularly railway switch.
Background technology
The existing straight Qu Yidong switch apparatus of doing traveling priority, its structure is as Figure 1-3: when track switch is received after unlock command, electric pushrod moves backward, leaves lock pin case, encounters limit switch, motor stops operating, release puts in place, and track switch receiving locks onto after bit instruction, and running motor reducer rotates, the integral translation of switch with follow up movement beam, changes the connection (Fig. 2 becomes Fig. 3) of side line position into from the connection of straight line position; Or become the connection (Fig. 3 becomes Fig. 2) of straight line position from the connection of side line position.The motion track of track switch is straight line.
Thisly be designed with the width that a very large shortcoming is exactly track switch, length be subject to safe distance reserved between track switch beam to affect structure larger.
Mobile N rice apart from time, the design width of track switch: the single deck-siding of the single deck-siding+2S=2N+ of H1 >=3X track switch track switch.
Wherein: S be vehicle from track switch through out-of-date, reserved safe distance between track switch beam.For maglev vehicle, be generally not less than 0.2m.
For instance, when two line pitch N are 3m, single track is wide while being 2m, H >=2X3+2=8m.
In urban track traffic, switch structure design is compacter, occupation of land is fewer, engineering cost and cost are lower, particularly, in the wider situation of vehicle, rail beam beam, appropriate design, reduces track switch size, just can reduce construction costs, line design person usually proposes meeting under train-passing through conditions, reduces the requirement of track switch size, to facilitate line design.
Summary of the invention
The present invention seeks to design the straight bent portable shunt of a kind of monorail transit, to overcome existing track switch, take up an area greatly the problem that cost is high.
The straight bent portable shunt of monorail transit, has He Ce station track, straight station track, it is characterized in that He Ce station track, straight station track is formed and formed respectively the walking rails of vehicle by bent two turnout rail beams and the running face on it always; Turnout rail beam is arranged on chassis, and chassis is placed on by drive unit, to drive to crank arm on walking rails and moves in guide groove, and guide groove is arranged on straight turnout rail beam and drives straight station track, side station track to rotate together the connection that realizes another circuit; Simultaneously crank device is arranged on and is fixed on motor reducer on the ground and motor reducer drives crank to rotate, and the roller on crank device is located in guide groove and can slides, and stirs guide groove and the turnout rail beam that is connected with guide groove moves.
Advantage of the present invention is:
1, comparing the structure of design with the track switch of doing traveling priority can be compact, saves land resources, for the route selection of line design brings great flexibility.
2, compare with the chain type track switch of the linear replace curve by straight line that can change, after this track switch curve Alignment Design processes, just no longer change, therefore can design dock with fixed line very smooth-going, vehicle impacts during by track switch little from curve branch road, in the middle of track switch beam, there is no deformation mechanism, so safety and maintainable good.

The specific embodiment
For meet monorail transit to design site requirements, meet the requirement of vehicle thread-changing, meet the functional requirement of track switch simultaneously, newly-designed middle low speed magnetic floating parallel-moving type track switch should reach following requirement:
1) by movement, can connect many circuits such as straight line and curve;
2) switch structure design should be compact;
3) when vehicle is by track switch curve, should operate steadily.
Structural concept: straight station track 6, side station track 7 are comprised of bent two turnout rail beams 4 and the running face on it always respectively, form the walking rails of vehicle.Turnout rail beam 4 is arranged on chassis 2, chassis 2 is placed on walking rails 5, drives to crank arm 8 in guide groove 9, move by drive motors 3, and guide groove 9 is arranged on straight turnout rail beam 4, drive straight station track 6, side station track 7 to turn an angle together, realize the connection of another circuit.Crank is stirred the principle of track switch rotation as Fig. 2, crank device is arranged on and is fixed on motor reducer on the ground, when motor reducer drives crank to rotate, the roller 11 on crank device 8 slides in guide groove 9, stirs guide groove 9 and the turnout rail beam 4 that is connected with guide groove 9 moves.
B, operating principle (shown in Fig. 9)
Track switch is crossed car under lock-out state, in figure, dotted line is that vehicle passes through track switch from side line, and the gap that the position that track switch is turned and fixed beam can keep dmm, does not bump, vehicle by time and clamped beam have uniform gap d, meet the necessary condition that vehicle does not bump by track switch.
C, operating principle (shown in Figure 10-1,10-2)
During track switch thread-changing, by two cranks, in guide groove, stir track switch, a straight beam and a curved beam are rotated a certain angle around center of circle O, connect straight line position after upwards turning certain angle, connect side line position after rotating certain angle simultaneously.The installation site that the angle of rotation is cranked arm by former and later two, the length that former and later two are cranked arm, former and later two these six data of angle [alpha] that turn over of cranking arm are coordinated to guarantee.
Figure 11 is for rotating right and wrong track switch design scheme flow chart, rotate right and wrong track switch design scheme mobile N rice apart from time, the design width of track switch:
The single deck-siding of the single deck-siding+S+3/4 of H2 >=2X track switch track switch single deck-siding=N+7/4 track switch
Wherein: S be vehicle from track switch through out-of-date, reserved safe distance between track switch beam, is generally not less than 0.2m for maglev vehicle.
For instance, when two line pitch N are 3m, track is wide while being 2m,
Single deck-siding=the 3+ of H2 >=N+7/4 track switch (7/4) X2=6.5 (m)
All reduce with the comparison length and width size of doing the right and wrong track switch design scheme of traveling priority, be calculated as follows:
One, deck-siding reduces H2-H1=8-6.5=1.5 (m);
Two, beam length is learnt M2-M1=4(m according to mapping).
By accurate mapping, determine the center of rotation of track switch, the radius of gyration at the two ends of crank length, track switch, the curve form of branch line of turnout and sweep, in order to prevent there is derailment occurring when track switch is moved, track switch one end chassis should be made the form of wheel rim.
