Abstract

The utility model aims to design a monorail traffic straight and curved movable type track switch to overcome problems that a conventional track switch occupies a large area and is high in cost. A straight track of the monorail traffic straight and curved movable type track switch is composed of straight track switch track beams and a running surface on the beams, and a side track of the monorail traffic straight and curved movable type track switch is composed of curved track switch track beams and a running surface on the beams, thereby forming running tracks for vehicles. The track switch track beams are arranged on a bench vehicle which is placed on the running tracks to drive a crank arm to move in a guide groove via a driving device. The guide groove is arranged on the straight track switch track beams to drive the straight track and the side track to rotate together, thereby connecting another line. Meanwhile, the crank arm is disposed on a motor decelerator fixed to the ground, and the motor decelerator drives the crank arm to rotate. Rollers on the crank arm are positioned in the guide groove and can slide to trigger the guide groove and the track switch track beams connected with the guide groove to move. Compared with track switches moving in a linear manner, the monorail traffic straight and curved movable type track switch is more compact in structural design, enables land resources to be saved, and helps to bring great flexibility for selection of lines.

Description

The straight bent portable shunt of monorail transit

Technical field

The utility model belongs to the improvement in track traffic facility technology field, particularly railway switch.

Background technology

The existing straight Qu Yidong switch apparatus moving linearly that does, 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.Generally be not less than 0.2m for maglev vehicle.

For instance, in the time that 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 utility model object is the straight bent portable shunt of a kind of monorail transit of design, takes up an area greatly the problem that cost is high to overcome existing track switch.

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 to drive to crank arm by drive unit 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.

The utility model has the advantages that:

1, the structure of design can be compact compared with doing the track switch moving linearly, and saves land resources, for the route selection of line design brings great flexibility.

2, compared 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, therefore safety and maintainable good.

Detailed description of the invention

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) can connect many circuits such as straight line and curve by movement;

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 made up 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, in the time that 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.

1C, operating principle (shown in Figure 10-1,10-2)

When track switch thread-changing, in guide groove, stir track switch by two cranks, 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 ensure.

Figure 11 for rotate 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 moving linearly, 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 in the time that track switch is moved, track switch one end chassis should be made the form of wheel rim.
