The driving component 2 is fixedly connected to the lower part of the rotating shaft 9 through a connecting plate 12, and the transmission component 3 is in power coupling connection with the driving component 2. In the process of switching the turnout, the transmission assembly 3 and the driving assembly 2 rotate along with the rotating assembly 1, the limiting device limits the driving assembly 2 and the transmission assembly 3 to rotate within a certain range, and the phenomenon that the steel wire rope driving device is damaged due to large-angle rotation when the turnout is started or stopped or breaks down is avoided.
The rotating assembly 1 is composed of a shaft seat 5, a rotating shaft 9, a limiting device, a sealing cover 6, a plane bearing 10, a ball bearing 11 and an electric bidirectional self-locking device 29.

The extension and retraction of the two electric pawls 30 are controlled by electric signals, so that only one pawl and the corresponding ratchet form a ratchet structure all the time, and the reverse limiting effect on the rotating shaft 9 is achieved. The sealing cover 6 is detachably connected to the shaft seat 5 to prevent dust and other foreign matters from falling into the plane bearing 10 and the ball bearing 11. Similarly, the lower part of the shaft seat 5 is provided with a sealing ring for sealing and dust prevention.
Particularly, the rotating shaft 9 is installed inside the shaft seat 5 through the ball bearing 11 and the plane bearing 10, the rotating shaft 9 can freely rotate inside the shaft seat 5, the plane bearing 10 plays a supporting role for the rotating shaft 9, and the ball bearing 11 plays a limiting role for the rotating shaft 9.
Particularly, the shaft seat 5 bears the dead weight of the rotating shaft 9, the driving component 2 and the transmission component 3, and the driving force transmitted to the turnout beam body by the steel wire rope driving device in the turnout driving process is large in bearing, so that the connection mode of the shaft seat 5 and the turnout beam bottom plate 4 needs to be firm and reliable, and is preferably welded and connected.
The drive assembly 2 is composed of an encoder 13, a drive motor 14, a reducer 15, and a housing 23. The driving motor 14 is fixedly connected to the lower part of the rotating shaft 9 through a connecting plate 12, the input end of the speed reducer 15 is connected with the driving motor 14, the output end of the speed reducer 15 is connected with the input end of the clutch, and the output end of the clutch is connected with one end of the coupler 16. The encoder 13 is mounted on the drive motor 14. The housing 23 is composed of two half groove structures, is connected to the driving motor 14, plays a role in protecting the transmission assembly 3, prevents dust, sundries and the like from falling into the transmission assembly 3, avoids the transmission assembly 3 from breaking down, and prolongs the service life. The housing 23 is provided with a waist-shaped hole for the steel wire rope to pass through.
Preferably, the housing 23 is connected to the drive motor 14 by means of bolts or screws, so that the housing 23 can be removed for maintenance in the event of a failure of the transmission assembly 3.
The transmission assembly 3 comprises a reel I17, a stop block 18, a reel II 19, a reel III 20, an end stop block 21, an end face sealing plate 22, a steel wire rope I24, a steel wire rope II 25, a steel wire rope III 26 and a transmission shaft 27.
Preferably, the transmission shaft 27 is connected with the coupling 16 and the reel in a key connection mode.
Preferably, the connection between the end stop 21 and the end closure plate 22 is a threaded connection.
Preferably, the connection between end stop 21 and reel iii 20 is by welding.
Particularly, the steel wire rope I24 and the steel wire rope III 26 have the same model size and specification, and the diameter is smaller than that of the steel wire rope II 25.
Specifically, the steel wire ropes I24 and III 26 are wound in the same manner, and the winding direction is opposite to that of the steel wire rope II 25.
Specifically, after the steel wire ropes I24, II 25 and III 26 are wound, the steel wire ropes are wound from the upper parts of the reel I17, II 19 and III 20, or the steel wire ropes are wound from the lower parts.
Particularly, the steel wire rope I24, the steel wire rope II 25 and the steel wire rope III 26 are in a tightening state after being wound, the tightening force of the steel wire rope I24 is equal to that of the steel wire rope III 26, and the tightening force is half of that of the steel wire rope II 25.
The driving mode of the steel wire rope driving device is as follows:
when the turnout system receives a switch instruction, the control device sends a turnout unlocking command, the turnout locking device starts unlocking, after the turnout locking device is unlocked in place, the locking device feeds an unlocking in-place signal back to the control device, after the control device receives the unlocking in-place signal, a starting instruction is sent to the driving motor 14, the driving motor 14 is started to operate, and the driving shaft 27 and a reel arranged on the driving shaft 27 are driven to synchronously rotate through the coupler 16. Because the wire rope twines on the reel, wire rope one end is linked firmly on the reel, the other end is linked firmly on spud 28, and wire rope all is in the state of tightening, so when the reel rotated to a certain direction, wire rope I24 and wire rope III 26 will wind into and around on reel I17 and reel III 20 (or wind out reel I17 and reel III 20), wire rope II 25 will wind out reel II 19 (or wind into and wind on reel II 19), then the reaction force that reel I17 and reel III 20 acted on wire rope I24 and wire rope III 26 (or reel II 19 acted on wire rope II 25) will stimulate the switch roof beam body to move along the direction that wire rope I24 and wire rope III 26 twined and shorten (or along the direction that wire rope II 25 twined and shortens). Thus, the switch beam body realizes the switch movement.
The encoder 13 converts the rotation angle of the driving motor 14 into an electric signal, and transmits the electric signal to the control device in real time, when the driving motor 14 rotates to a preset angle, the turnout beam body is switched in place, the control device sends out a stop and locking instruction, the driving motor 14 stops running, the turnout locking device completes locking, and a locking in-place signal is fed back to the control device. The turnout device completes one-time switching.
In particular, because the reel I17, the reel II 19 and the reel III 20 are identical in shape and size and are all arranged on the transmission shaft 27, when the transmission shaft 27 rotates, the lengths of the steel wire rope I24 and the steel wire rope III 26 wound into (or wound out of) the reel I17 and the reel III 20 are equal to the lengths of the steel wire rope II 25 wound out of (or wound into) the reel II 19, and therefore the steel wire rope I24, the steel wire rope II 25 and the steel wire rope III 26 are all in a tightening state all the time. When the turnout beam body moves along the direction that the steel wire I24 and the steel wire III 26 are wound and shortened, the steel wire II 25 plays a role in reversely tensioning and limiting the turnout beam body, and vice versa.
In particular, the integral turnout switch rotates around the tail shaft. During the switch process, the transmission assembly 3 and the driving assembly 2 are rotated through the rotating assembly 1 to adjust the position, so that the transmission shaft 27 is ensured to be perpendicular or approximately perpendicular to the steel wire rope, and the axial force of the steel wire rope to the transmission assembly 3 and the driving assembly 2 during the driving process is reduced or eliminated.
Finally, it should be noted that: various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
