The inner ends of the third connecting rod 16 are respectively connected to the second swing rack 13 and the third swing rack 14, and the outer ends are hinged to the right end of the T-shaped crank arm;

[0031] It includes a fourth connecting rod 17 arranged below the tips of the first swing rack 12 and the second swing rack 13. The inner ends of the fourth connecting rod 17 are respectively connected to the first swing rack 12 and the fourth swing rack 15, and the outer ends are hinged to the left end of the T-shaped crank arm.

[0032] The straight rack 9, curved rack 10, first swing rack 12, second swing rack 13, third swing rack 14 and fourth swing rack 15 are respectively arranged on corresponding slide plates, and the arrangement method of the slide plates is the same as that of the prior art.

[0033] The heel ends of the first swing rack 12, the second swing rack 13, the third swing rack 14, and the fourth swing rack 15 are vertically hinged and fixed to ensure that the first swing rack 12, the second swing rack 13, the third swing rack 14, and the fourth swing rack 15 can flexibly swing in the horizontal plane. There are two types of hinged fixing methods: the first is that the heel ends of the first swing rack 12 and the second swing rack 13 are vertically hinged to the straight rack 9 at the connection point, and the heel ends of the third swing rack 14 and the fourth swing rack 15 are vertically hinged to the curved rack 10 at the connection point; the second is that the heel ends of the first swing rack 12, the second swing rack 13, the third swing rack 14, and the fourth swing rack 15 are respectively fixed with hinge seats on the switch sleepers, and the heel ends of the first swing rack 12, the second swing rack 13, the third swing rack 14, and the fourth swing rack 15 are respectively vertically hinged to the hinge seats.

[0034] To ensure smooth, flexible, and accurate movement of the second connecting rod 11, a guide support device 19 is provided between the first hinge seat 2 and the second hinge seat 3, and the second connecting rod 11 is slidably connected to the guide support device 19. A preferred embodiment of the sliding connection is to provide a nylon sleeve on the guide support device 19, through which the second connecting rod 11 passes and is guided and slidable.

[0035] The first articulated seat 2, the second articulated seat 3 and the supporting device 19 are preferably fixed to the corresponding switch sleepers of the steel rail switch via a supporting plate to simplify the structure and facilitate installation.

[0036] Working principle: The switch machine 1 drives the first connecting rod 6 to move toward the straight side of the switch, and the first connecting rod 6 drives the curved point rail 7 to close and the straight point rail 8 to separate. At the same time, the first connecting rod 6 drives the L-shaped turning arm to rotate clockwise, and pulls the second connecting rod 11 to move to the left through the L-shaped turning arm, and then pulls the T-shaped turning arm to rotate clockwise through the second connecting rod 11. The T-shaped turning arm drives the third connecting rod 16 to move toward the curved side of the switch and drives the fourth connecting rod 17 to move toward the straight side of the switch. The second swing rack 13 and the third swing rack 14 are driven to swing clockwise through the third connecting rod 16, and the first swing rack 12 and the fourth swing rack 15 are driven to swing clockwise through the fourth connecting rod 17, thereby separating the tips of the first swing rack 12 and the second swing rack 13, and closing the third swing rack 14 and the fourth swing rack 15, thereby realizing the opening of the curved section of the switch.

[0037] When the straight section of the switch needs to be opened, the switch machine 1 drives the first connecting rod 6 to move toward the side of the curved section of the switch, and the first connecting rod 6 drives the curved point rail 7 to separate and the straight point rail 8 to close. At the same time, the first connecting rod 6 drives the L-shaped turning arm to rotate counterclockwise, and pushes the second connecting rod 11 to move to the right through the L-shaped turning arm, and then pushes the T-shaped turning arm to rotate counterclockwise through the second connecting rod 11. The T-shaped turning arm drives the third connecting rod 16 to move toward the side of the straight section of the switch and drives the fourth connecting rod 17 to move toward the side of the curved section of the switch. The second swing rack 13 and the third swing rack 14 are driven to swing counterclockwise through the third connecting rod 16, and the first swing rack 12 and the fourth swing rack 15 are driven to swing counterclockwise through the fourth connecting rod 17, so that the tips of the first swing rack 12 and the second swing rack 13 are closed, and the third swing rack 14 and the fourth swing rack 15 are separated, thereby realizing the opening of the straight section of the switch.

[0038] Combined with attachment Figure 1 、 2 , 5 describe the second embodiment of the present invention.

[0039] The basic structure and working principle are the same as those of the first embodiment, except that: on the basis of the first embodiment, the L-shaped crank arm is replaced by a T-shaped crank arm, and the T-shaped crank arm is replaced by a cross-shaped crank arm, and the middle end of the T-shaped crank arm is facing the left, and a fifth connecting rod 18 is added; the middle end of the T-shaped crank arm is hinged to the end of the first connecting rod 6, and the other two ends are hinged to one end of the second connecting rod 11 and the fifth connecting rod 18 respectively; the other ends of the second connecting rod 11 and the fifth connecting rod 18 are hinged to the vertical ends of the cross-shaped crank arm respectively, and the lateral ends of the cross-shaped crank arm are hinged to the outer ends of the third connecting rod 16 and the fourth connecting rod 17 respectively.

[0040] The second connecting rod 11 and the fifth connecting rod 18 are respectively slidably connected to the guide support device 19. That is, the guide support device 19 is provided with a pair of nylon sleeves, and the second connecting rod 11 and the fifth connecting rod 18 respectively pass through the pair of nylon sleeves to achieve guided sliding.

[0041] When the curved section is opened, the switch machine 1 pushes the first connecting rod 6 to move toward the straight section of the switch, and drives the curved point rail 7 to close and the straight point rail 8 to separate through the first connecting rod 6. At the same time, the first connecting rod 6 pushes the T-shaped turning arm to rotate clockwise, and simultaneously pulls the second connecting rod 11 to move left and pushes the fifth connecting rod 18 to move right through the T-shaped turning arm, and then pulls the T cross-shaped turning arm through the second connecting rod 11 and the fifth connecting rod 18 to push the cross-shaped turning arm clockwise. The cross-shaped turning arm drives the third connecting rod 16 to move toward the curved section of the switch and drives the fourth connecting rod 17 to move toward the straight section of the switch. The second swing rack 13 and the third swing rack 14 are driven to swing clockwise through the third connecting rod 16, and the first swing rack 12 and the fourth swing rack 15 are driven to swing clockwise through the fourth connecting rod 17, thereby separating the tips of the first swing rack 12 and the second swing rack 13, and closing the third swing rack 14 and the fourth swing rack 15, thereby realizing the opening of the curved section of the switch.

[0042] When the straight strand is opened, the switch machine 1 pulls the first connecting rod 6 to move toward the side of the switch curved strand, and drives the curved point rail 7 to separate and the straight point rail 8 to close through the first connecting rod 6. At the same time, the first connecting rod 6 pulls the T-shaped crank arm to rotate counterclockwise, and simultaneously pushes the second connecting rod 11 to move right and pulls the fifth connecting rod 18 to move left through the T-shaped crank arm, and then pushes the T cross-shaped crank arm through the second connecting rod 11, and the fifth connecting rod 18 pulls the cross-shaped crank arm to rotate clockwise. The cross-shaped crank arm drives the third connecting rod 16 to move toward the side of the switch straight strand and drives the fourth connecting rod 17 to move toward the side of the switch curved strand, and drives the second swing rack 13 and the third swing rack 14 to swing counterclockwise through the third connecting rod 16, and drives the first swing rack 12 and the fourth swing rack 15 to swing counterclockwise through the fourth connecting rod 17, thereby closing the tips of the first swing rack 12 and the second swing rack 13, and separating the third swing rack 14 and the fourth swing rack 15, thereby realizing the opening of the switch straight strand.

[0043] It should be noted that the term "left side" in the above description refers to the side facing the switch point rail, "right side" refers to the side away from the switch point rail, "left end" refers to the end close to the switch point rail, "right end" refers to the end away from the switch point rail, "inside" refers to the side facing the switch curve, "outside" refers to the side away from the switch curve, "inner end" refers to the end close to the switch curve, and "outer end" refers to the end away from the switch curve.
