In-place detection device for suspension type monorail turnout transposition switch mechanism

Abstract

According to the in-place detection device for the transposition switch mechanism of the suspension type monorail turnout, a proximity switch is arranged on a turnout beam of the suspension type monorail turnout, and an induction plate is arranged on the outer side of a turnover plate of the switch mechanism; when the turnout switches to the in-place position, the induction plate rotates by 90 degrees along with the turnover plate to be close to the proximity switch so that the proximity switch can send out an in-place signal. When the turnout leaves the in-place position, the induction plate reversely rotates by 90 degrees along with the turnover plate to be away from the proximity switch, and the in-place signal disappears. According to the invention, the proximity switch technology is applied to high-precision detection of the in-place condition of the turnout, so that the accuracy of the detection result is ensured, and the safety and reliability of turnout operation are improved.

[0021] like Figure 1 As shown, when this invention is applied to the "Suspended Monorail Transit System Running Surface Flipping and Repair Turnout Switching Mechanism CN 207670429 U", a proximity switch 2 is provided on the turnout beam 6 of the suspended monorail turnout, and a sensing plate 1 is provided on the outer side of the flipping plate 7 of the switching mechanism; when the turnout switches to the correct position, the sensing plate 1 rotates 90° along with the flipping plate 7 to approach the proximity switch 2, causing the proximity switch 2 to send a position signal; when the turnout leaves the correct position, the sensing plate 1 rotates 90° in the opposite direction along with the flipping plate 8 to move away from the proximity switch 2, and the position signal disappears.

[0022] like Figure 2 As shown, an L-shaped bracket 1-1 is fixed to the outside of the flip plate 8, and a pair of sensing plates 1 are symmetrically fixed to the top of the L-shaped bracket 1-1; a U-shaped bracket 2-1 with its opening facing downward is fixed on the turnout beam 6, and a pair of proximity switches 2 are symmetrically fixed on both sides of the U-shaped bracket 2-1, with their sensing ends located in the inner cavity of the U-shaped bracket 2-1; when the flip plate 7 rotates 90°, a pair of sensing plates 1 enter the inner cavity of the U-shaped bracket 2-1 and approach a pair of proximity switches 2 respectively, and the L-shaped bracket 1-1 is fixed to the flip plate 7 by the first bolt pair 3.

[0023] like Figure 3 As shown, the sensing plate 1 is L-shaped, with a first strip-shaped hole 1-2 in the middle of its horizontal end along the circuit direction. The top of the L-shaped bracket 1-1 has a second strip-shaped hole 1-3 perpendicular to the first strip-shaped hole 1-2. A second bolt 4 passes through the first strip-shaped hole 1-2 and the second strip-shaped hole 1-3 respectively, fixing the sensing plate 1 to the top of the L-shaped bracket 1-1. The bolt can be adjusted both perpendicular to and along the circuit direction. This ensures that the sensing plate remains within the sensing area of ​​the proximity switch after rotation.
