[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1-4 As shown, the coupling 4 monitoring limit device provided by the present invention includes a protruding device 1, a transmission rod 2 and a limit switch 3. The protruding device 1 is installed on the outside of the coupling 4. The coupling 4 is installed on the output shaft of the reducer and rotates with the output shaft of the reducer. Figure 2 As shown, one end of the transmission rod 2 contacts the housing of the coupling 4, and the other end of the transmission rod 2 is fixed to the rotating shaft 5. The rotating shaft 5 is rotatably mounted on the outside of the limit switch 3, and a reset torsion spring 6 is provided outside the rotating shaft 5. Figure 3The raised device 1 shown drives the transmission rod 2 to rotate as the coupling 4 rotates to the end of the transmission rod 2. As the coupling 4 continues to rotate, the raised device 1 gradually loses contact with the transmission rod 2, and the transmission rod 2 contacts the outer shell of the coupling 4 again. The rotating shaft 5 rotates clockwise and counterclockwise alternately under the action of the reset torsion spring 6. The transmission rod 2 resets its end under the action of the restoring force of the reset torsion spring 6 and contacts the surface of the coupling 4 again. The rotation angle of the transmission rod 2 is limited and swings back and forth. The rotation and swinging process of the transmission rod 2 drives the rotating shaft 5 to rotate. The raised point 7 on the rotating shaft 5 intermittently touches the contact 8 on the limit switch 3 during the rotation of the rotating shaft 5. Through the above process, the rotation of the coupling 4 is transmitted to the limit switch 3 through the raised device 1 and the transmission rod 2, triggering the signal of the contact 8 of the limit switch 3, which is transmitted to the control room, so that the operating status of the reducer can be monitored in real time.

[0019] In the present invention, the axis of the transmission rod 2 is arranged perpendicular to the axis of the rotating shaft 5, the transmission rod 2 is fixedly installed with the rotating shaft 5 through the mounting block 9, the axis of the transmission rod 2 is arranged radially along the output shaft of the reducer, and the mounting angles of the transmission rod 2 and the rotating shaft 5 are reasonably set, so that the rotation of the coupling 4 is smoothly transmitted to the limit switch 3 through the protruding device 1 and the transmission rod 2.

[0020] In one embodiment, the outer surface of the protrusion device 1 is set as an arc-shaped protrusion and is fixed to the coupling 4 by welding. The arc-shaped protrusion can reduce the resistance when the protrusion device 1 contacts the transmission rod 2 when the coupling 4 rotates, thereby reducing the loss of the transmission rod 2.

[0021] Furthermore, a pulley 13 is provided on the top of the transmission rod 2, and the pulley 13 is rotatably installed on the end of the transmission rod 2 through the bracket 12. The pulley 13 can rotate freely when it contacts the arc-shaped protrusion. The pulley 13 cooperates with the arc-shaped protrusion to further reduce the resistance when the protrusion device 1 touches the transmission rod 2.

[0022] The limit switch 3 is fixed on the mounting frame 11, and a sleeve 10 is provided on the mounting frame 11. The middle part of the rotating shaft 5 is rotatably mounted with the sleeve 10, and the reset torsion spring 6 is provided at the end of the sleeve 10. The protrusion 7 is provided on the outer side of the end of the rotating shaft 5 close to the contact 8 of the limit switch 3. The transmission rod 2 rotates back and forth in the sleeve 10. The setting of the sleeve 10 makes the transmission rod 2 rotate more smoothly. The sleeve 10 is also the installation position of the reset torsion spring 6.

[0023] The reducer coupling 4 in the present invention is a TL type elastic sleeve pin coupling 4 with a shaft hole diameter of 40 and an outer diameter of 400; the limit switch 3 is LXK3-20S / T; and the protruding device 1 is arc cast iron.

[0024] Traditional reducers are operated by being dragged by motors, and all operating states and protections are realized through the electrical protection of the motor, without realizing operating state monitoring for the reducer body. The utility model utilizes a protruding device welded on the reducer coupling, so that the operating state of the reducer is transmitted through the protruding device welded on the coupling by periodically contacting the transmission rod. The transmission rod periodically triggers the contact signal of the limit switch, and transmits the contact signal of the limit switch to the monitoring personnel in the main control room, forming a periodic cycle, thereby realizing monitoring of the operating state of the reducer.
