Description
Technical field
The utility model belongs to stock rail turnout technology field, relates in particular to a kind of straddle-type monorail track switch blocking device.
Background technology
For guaranteeing the safe operation of Urban Elevated Light Rail vehicle, need be provided with on the front end chassis of each track switch beam special blocking device to the linear state of track switch and turn-out track after state position and lock, its reliability directly influences traffic safety, require accurate positioning and lock firmly, can overcome vehicle by the time centnifugal force and the impulsive force that produce.Early stage blocking device adopts direct insertion or weight hammer type structure, power to have to adopt pneumatic mode, also has to adopt hydraulic driving mode, but these complex structures, and particularity, poor reliability are operated very inconveniently, are eliminated already.Along with light rail vehicle designing and manufacturing level and the people raising to light rail vehicle travelling comfort, security requirement, the overhead road of city straddle-type monorail track switch blocking device of online use adopts driven by power, the rotary catch gear of T oblique crank Z usually in the world now.The present domestic urban light rail line of building and planning to build, its beam rail of forming simple turnout is partly grown (about 22m) and heavy (about 35 tons), when making this huge system with the peak by higher frequency (as come and go 1 time/2.5min) carry out accurate turn-out track (the turn-out track precision should reach more than the 2mm), for this reason, need design one cover reliability height, coupling mechanism force is big, and the locking and unlocking movement response is fast, and realizes that easily the automatically controlled blocking device matches.
The utility model content
The purpose of this utility model provide a kind of simple in structure, coupling mechanism force is big, the straddle-type monorail track switch blocking device that reliability is higher.
Straddle-type monorail track switch blocking device of the present utility model, comprise motor, lock slots and locking roller, motor is fixed on the base, the mouth of motor is connected with electric pushrod by speed reduction gearing, one end of electric pushrod is hinged with a pin of " " shape roller shaft, the locking roller is installed in another pin of " " shape roller shaft, and " " shape roller shaft is hinged on the erection support by rotating shaft, and erection support is fixed on the base.
Also be fixed with the latched position detecting device on the described base, " " shape roller shaft is provided with test bar, and the collision block of latched position detecting device end is positioned on the arc rotary motion trace of test bar end.
Also be provided with hand wheel on the described motor, hand wheel is fixed on an end of adapter shaft, and the other end of adapter shaft passes motor and links to each other with reducing gearbox.
Motor is through deceleration rear drive electric pushrod in the utility model, make electric pushrod produce vertical crank motion up and down, electric pushrod drives " " shape roller shaft again and rotates around its hinge-point, and " " shape roller shaft drive locking roller rolls and into finishes locking in the lock slots.Electric pushrod thrust is big, and the stroke of bar is short, good rigidly; Lock slots be about two walls the version at certain inclination angle is arranged, when the track switch turn-out track is slightly not in place,, promotes track switch and put in place as long as the locking roller will produce very big horizontal component of force in the angle of lock slots.Setting up of test bar and latched position detecting device puts changing points in place and passes out a signal during positive lock, to guarantee the safe operation of vehicle.Setting up of hand wheel is in order to have a power failure or during the electric elements et out of order, can finish the locking and unlocking work of track switch by manual.
The beneficial effects of the utility model are: simple in structure, coupling mechanism force is big, the reliability height does not need additional equipment (as Air compressor, Hydraulic Station etc.), and the locking and unlocking movement response is fast, realizes automatic guidance easily.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 2, the utility model is by motor 1, electric pushrod 2, " " shape roller shaft 3, locking roller 4, lock slots 5, latched position detecting device 6, hand wheel 7, adapter shaft 8, base 9, rotating shaft 10, erection support 11, test bar 12 and reducing gearbox 13 are formed, motor 1 is fixed on the base 9, the mouth of motor 1 is connected with electric pushrod 2 by reducing gearbox 13, one end of electric pushrod 2 is hinged with a pin of " " shape roller shaft 3, locking roller 4 is installed in another pin of " " shape roller shaft 3, " " shape roller shaft 3 is hinged on the erection support 11 by rotating shaft 10, and erection support 11 is fixed on the base 9.Electric pushrod 2 thrusts are big, and the stroke of bar is short, and good rigidly helps locking the positive lock of roller 4.
As can be seen from Figure 2: be fixed with latched position detecting device 6 on the described base 9, " " shape roller shaft 3 is provided with test bar 12, and the collision block 6a of latched position detecting device 6 ends is positioned on the arc rotary motion trace of test bar 12 ends.When electric pushrod 2 moves downward, promoting " " shape roller shaft 3 clockwise directions rotates, making locking roller 4 enter lock slots 5 locks when putting in place, test bar 12 just in time turns to " " shape roller shaft 3 clockwise directions and makes its end touch the collision block 6a of latched position detecting device 6 ends, sensor on the collision block 6a spreads out of a locking signal to control center, but the safe operation of expression vehicle is passed through.
As can be seen from Figure 2: described motor 1 is provided with hand wheel 7, and hand wheel 7 is fixed on an end of adapter shaft 8, and the other end of adapter shaft 8 passes motor 1 and links to each other with reducing gearbox 13.When having a power failure or during the electric elements et out of order, can be by artificial rotation manual runner 7, and drive electric pushrods 2 by reducing gearbox 13 and move, thereby can finish the locking and unlocking work of track switch by hand.
Principle of work: during use, this blocking device is fixed by bolts on the track switch beam chassis by base 9, lock slots 5 transfixion that is fixed, when track switch beam turn-out track puts in place need lock the time, motor 1 starts, the output torque of motor 1 moves straight down through reducing gearbox 13 deceleration rear drive electric pushrods 2, and electric pushrod 2 drives " " shape roller shaft 3 again and rotates around its hinge-point, and " " shape roller shaft 3 drives 4 rollings of locking roller to be advanced in the lock slots 5 to finish locking; When locking roller 4 is locked into place, test bar 12 just in time turns to " " shape roller shaft 3 clockwise directions and makes its end touch the collision block 6a of latched position detecting device 6 ends, sensor on the collision block 6a spreads out of a locking signal to control center, but the safe operation of expression vehicle is passed through.Action is with above-mentioned opposite during the track switch release.When having a power failure or during the electric elements et out of order, can be by artificial rotation manual runner 7, and drive electric pushrods 2 by reducing gearbox 13 and move, thereby can finish the locking and unlocking work of track switch by hand.
