[0044] The pipe column sensing structure is used to sense whether there is a pipe column in the main body 1 of the elevator. Its working principle is as follows: when there is a pipe column in the pipeline hole 2, the pipe column applies a force to the pipe column sensing block 302, pushing the pipe column sensing block 305 to move downward until it is completely placed in the pipe column sensing notch 305. At the same time, the pipe column sensing block 305 will push the pipe column sensing pin 303 connected to it to retreat until its outer end is placed under the pipe column sensing proximity switch 301. After the pipe column sensing proximity switch 301 senses the pipe column sensing pin 303, it is determined that there is a pipe in the pipeline hole 2 and sends the signal to the relevant control system. When there is no pipe in the pipeline hole 2, the pipe column sensing compression spring 304 will drive the pipe column sensing pin 303 to return to its original position, and then drive the pipe column sensing block 302 back to the initial position. At the same time, the pipe column sensing proximity switch 301 cannot sense the pipe column sensing pin 303, and sends a signal to the relevant control system that there is no pipe column in the main body 1 of the elevator.

[0046] The pipe column pressure sensing structure is used to sense whether there is pipe column pressure in the main body of the elevator, and is used to further determine the working state of the main body of the elevator. When there is pipe column pressure, the pipe column applies a downward force to the coupling pipe column sensing pin 310, and the coupling pipe column sensing pin 310 descends to force the pipe column pressure sensing block 312 connected to it to move. The movement of the pipe column pressure sensing block 312 drives the pipe column pressure sensing pin 313 to move to the sensing area of ​​the pipe column pressure sensing proximity switch 311. The pipe column pressure sensing proximity switch 311 obtains the pipe column pressure signal and sends it to the relevant control system. When there is no pipe column pressure, the rebound force of the pipe column pressure sensing compression spring 314 will drive the pipe column pressure sensing pin 313, the pipe column pressure sensing block 312, and the coupling pipe column sensing pin 310 back to the initial position.

[0047] The pipe column pressure sensing structure cooperates with the pipe column sensing structure to judge whether there is a pipe column in the elevator body 1, whether the pipe column is pressed down, and what state the pipe column is in the elevator body, thereby obtaining a comprehensive state judgment of the pipe column in the elevator body 1.
