The utility model relates to the used flexible joint track switch of PC rail beam in a kind of sliding wedge type flexible joint track switch, particularly straddle-type monorail transportation system.
In straddle-type monorail transportation system, normal use track switch is carried out line transfer, the rail beam that its track switch is used adopts the girder steel of hollow I shape section more, the span of this rail beam is about 5 meters, Fig. 6 is flexible joint, the four joints track switch of using always, in this track switch, wherein each flexible joint track switch can be carried out the amount of deflection variation, Fig. 7 is the common flexible joint track switch that Japanese main track uses, Fig. 8 is a common flexible joint track switch distortion schematic diagram, in above-mentioned track switch, a beam body 101 is arranged, running face 102 is arranged at its top, andante 103 is walked on top, steadying plate 104 is arranged at the bottom, the beam body be provided with a plurality of can axially movable mobile link 105, described walk andante and steadying plate hinged by hinge and mobile link, there is a sliding pin 106 at the connecting rod middle part, be provided with a rotary drum curved surface chute 107 below the connecting rod, under the guiding of this chute, connecting rod can produce axial displacement, the size of its displacement is determined according to the design needs, the displacement of a plurality of connecting rods makes away andante and steadying plate produce required radian, and this class track switch can be described as cydariform flexible joint track switch, and there is following defective in this track switch:
1, the rotation of each rotary drum is by multistage connecting rod transmission, and not only complex structure, and cumulative errors is bigger, and displacement accuracy is lower.
2, described rotary drum design is in the beam body, and the operating space is narrow and small, and the curved surface chute is unfavorable for adjusting maintenance.
3, the rotary drum of Zhuan Donging is unfavorable for applying sliding agent.
4, the curved surface chute is unfavorable for processing.
5, fixed hinged seat is at the two ends of beam body, and therefore the connecting rod shift length at middle part is bigger.
The purpose of this utility model provides a kind of sliding wedge type flexible joint track switch, and this switch structure is simple, and is easy and simple to handle, adjusts easy to maintenance.
The purpose of this utility model is realized by following technical proposals: a kind of sliding wedge type flexible joint track switch, a beam body is arranged, running face is arranged at its top, andante is walked on top, steadying plate is arranged at the bottom, the beam body be provided with a plurality of can axially movable mobile link, and two fixed hinged seats, it is described that to walk andante hinged by hinge and mobile link and fixed hinged seat, on mobile link, be provided with sliding pin, below mobile link, have one vertical with mobile link and with the chute of the parallel installation of beam body, in this chute, be provided with a plurality of voussoirs, described chute and electric pushrod are installed, controlling it by this electric pushrod moves axially, described mobile link is installed in the two ends and the beam body middle part of beam body, and described two fixed hinged seats lay respectively between two mobile links on beam body both sides, and fix with the beam body.
The utility model with have technology to compare to have following advantage:
1, the utility model adopts the straight line chute, and voussoir is housed in the groove, and is simple in structure.
2, in the chute lubricating condition preferably can be arranged.
3, the utility model is installed when adjusting, and the axial location that only need change voussoir gets final product, and is easy to adjust.
4, electric pushrod adopts worm drive, and displaced position is accurately steady.
5, fixed hinged seat is located between two moving bars, and the shift length of mobile link is less.
The utility model is described in further detail below in conjunction with drawings and Examples.
