Turnout switch auxiliary lever device

The present invention relates to a tie rod device, and more particularly to a ballast switch auxiliary pull rod device.

Please refer to Fig. 1. When a track needs to be transferred, a turnout device must be installed on the road section of the basic track 300 on the branch. In it, the base rail 300 includes a linear basic rail 310 and a curved basic rail 320. The switch device includes a tip rail 400 and a switch lever 430. The tip rail 400 is disposed between the base rails 300. The tip rail 400 includes a linear tip rail 410 and a curved tip rail 420, wherein the curved tip rail 420 faces the straight line base rail 310. The linear tip rail 410 is adjacent to the curved basic rail 320; the switching rod 430 is disposed between the linear tip rail 410 and the curved tip rail 420. Moreover, the switch lever 430 is coupled to a switch 440 which provides a thrust or tension to the switch lever 430. When the switch 440 pushes the switch lever 430 to bring the curved tip rail 420 close to the linear basic rail 310, the curved tip rail 420 and the curved basic rail 320 form a curved guide rail, which can guide the train to other basic rails; When the trigger 440 pulls the switch lever 430 to bring the linear tip rail 410 close to the curved base rail 320, the linear tip rail 410 and the linear basic rail 310 form a straight guide rail for the train to advance along the straight line direction of the original basic rail 310.

The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of embodiments with reference to the drawings.

Referring to Figures 3 through 5, a ballast-turning auxiliary lever device 100 according to an embodiment of the present invention is provided for a base rail mounted on a track on a two-point rail that needs to be split and turned. The basic rail 300 includes a linear basic rail 310 and a curved basic rail 320. The tip rail 400 is disposed between the base rails 300. The tip rails 400 include a linear tip rail 410 and a curved tip rail 420, wherein the curved tip rail 420 faces the linear basic rail 310, and the linear tip rail 410 faces the curved basic rail 320.

The ballast-turning auxiliary lever device 100 according to an embodiment of the present invention includes a main switch lever 110, a first crank 120, an auxiliary switch lever 130, a second crank 140 and a transmission lever 150.

The main switch lever 110 is located at the end of the linear tip rail 410 and the curved tip rail 420. The main switch lever 110 has a first end opposite to the first end 111 and a second end 112, wherein the first end 111 is coupled to a switch 200, and the switch provides a thrust or tension to the main switch lever 110. Further, the main transfer lever 110 has a first inter-rail fixing rod 113 for being fixed between the linear tip rail 410 and the curved tip rail 420 of the tip rail 400.

The first crank 120 has an L-shape and has a first arm 121 and a second arm 122. The first crank member 123 is pivotally disposed on the body 160. Therefore, the first crank 120 can be the first shaft member 123. Rotate for the axis. The seat body 160 is fixed to a steel plate 170 which is lockable to the concrete pillow block 190 of the track. The first arm 121 of the first crank 120 is coupled to the second end 112 of the main switch lever 110.

The structure of the auxiliary switch lever 130 is similar to that of the main switch lever 110. That is, the auxiliary switch lever 130 also has a first end 131 and a second end 132 opposite to each other, and the auxiliary switch lever 130 has a second inter-rail fixing rod 133 for a straight line fixed to the tip rail 400. The position between the rail 410 and the curved tip rail 420 is different from the position of the first inter-rail fixing rod 113.

The structure of the second crank 140 is the same as that of the first crank 120. That is, the second crank 140 is also L-shaped, and has a first arm 141 and a second arm 142, and is pivoted to the body 160 by a second shaft member 143. Therefore, the second crank 140 can be The two shaft members 143 are rotated about the axis. The seat body 160 is also secured to a steel plate 170 that can be locked to the concrete pillow block 190 of the track.

The transmission rod 150 is coupled between the second arm 122 of the first crank 120 and the second arm 142 of the second crank 140. According to this, you can transfer the main switch The power of the drawbar 110 is sequentially transmitted to the auxiliary switch lever 130 via the first crank 120, the transmission lever 150, and the second crank 140, and the auxiliary switch lever is caused by the two turns of the first crank 120 and the second crank 140. 130 is in the same direction as the main switch lever 110. The outer circumference of a portion of the transmission rod 150 is covered with a guide ring 151 for stabilizing the transmission rod 150, so that the movement of the transmission rod is smoother. The guide ring 151 is also fixed to a steel plate 170 that can be locked to the concrete pillow block 190 of the track.

The switch-turning auxiliary lever device 100 further includes a third inter-rail fixing rod 180 for fixing between the linear tip rail 410 and the curved tip rail 420 of the tip rail 400, and between the first inter-rail fixing rod 113 and the second rail Between the fixed rods 133. The third inter-rail fixing rod 180 makes the gauge distance between the linear tip rail 410 of the tip rail 400 and the curved tip rail 420 more stable.

Referring to FIG. 4 together, when the track position of the track needs to be adjusted to the state of the curved track, the switch 200 is provided to provide a thrust to push the main switch lever 110 so that the end of the curved tip rail 420 is close to the straight basic track. At this time, the thrust of the main switch lever 110 is simultaneously transmitted to the auxiliary switch lever 130 via the first crank 120, the transmission rod 150 and the second crank 140, and the auxiliary switch lever is also in the direction of the thrust. The curved tip rail 420 at the location of the 130 is urged toward the linear base rail 310 such that the curved tip rail 420 and the curved base rail 320 form a curved guide for guiding the train to other basic rails.

Referring to FIG. 5 together, when the track position of the track needs to be adjusted to the state of the linear guide, the switch 200 is provided to provide a pulling force to push the main switch lever 110 so that the end of the straight line track 410 is close to the curved basic rail. At this time, the pulling force of the main switch lever 110 is simultaneously transmitted to the auxiliary switch lever 130 via the first crank 120, the transmission rod 150 and the second crank 140, and the auxiliary switch lever is also pulled in the direction of the pulling force. The linear tip rail 410 at the location of the 130 is pulled toward the curved base rail 320 such that the linear tip rail 410 and the linear base rail 310 form a straight rail for the train to travel in a straight line direction of the original base rail 300.

According to an embodiment of the present invention, the switch assisting pull rod device is provided with an auxiliary turn rod in a different position in addition to the original main switch rod, and the two transfer rods are synchronously operated in a coordinated manner. Turning action. Since the two-turning lever is located at different positions of the tip rail, the tip rail is applied with a balanced turning force at different positions, so that the turning rail pulling force can be reduced and sufficient displacement control is provided during the turning operation. It also maintains precise track alignment, gauge spacing and flange spacing, as well as maintaining good adhesion between the base rail and the tip rail.

Although the present invention is disclosed in the above embodiments, it is not intended to limit the present invention, and any person skilled in the art can make various changes and retouchings without departing from the spirit and scope of the novel food. The scope is subject to the definition of the scope of the patent application.
