The bottom of the dual-axis motor 321 is fixedly connected to the middle of the top of the cross plate 3110. Tapered teeth 322 are respectively fixedly connected to the left and right output ends of the dual-axis motor 321. Second tapered teeth 323 are meshed with the outer walls of the two tapered teeth 322. Screw rods 324 are fixedly connected to the inner walls of the two second tapered teeth 323. The front ends of the two screw rods 324 both extend to the front sides of the two screw rod support blocks 3111. The outer walls of the two screw rods 324 are respectively rotatably connected to the inner walls of the two screw rod support blocks 3111. Push-pull plates 325 are threadedly connected to the outer walls of the two screw rods 324. Rack bars 328 are fixedly connected to the bottoms of the two push-pull plates 325. Slide rods 326 are respectively fixedly connected to the front sides of the left and right sides of the two push-pull plates 325. The outer walls of the two groups of slide rods 326 are respectively slidably connected to the outer sides of the two groups of connecting blocks 316. Cylindrical pull rods 327 are fixedly connected to the front sides of the inner sides of the two groups of slide rods 326. The outer walls of the two cylindrical pull rods 327 are respectively slidably connected to the inner walls of the connecting block chutes 317 opened by the two groups of connecting blocks 316. The middle parts of the outer walls of the two cylindrical pull rods 327 are respectively slidably connected to the inner walls of the two oval chute blocks 333. The bottoms of the two rack bars 328 are meshed with the outer walls of the gear 313. Each of the two support rods 34 includes a support rod body 341. The outer walls of the two support rod bodies 341 are respectively slidably connected to the inner walls of the two groups of chute plates 314. Second rack bars 342 are fixedly connected to the tops of the two support rod bodies 341.

On the tops of the two support vertical rods 344, there are fixedly connected rubber blocks 345;

[0037] When the construction elevator is in use, the staff lowers the auxiliary pedal 33. First, the double-shaft motor 321 is started. The rotation of the motor is transmitted to the lead screw 324 through the tapered gear 322 and the second tapered gear 323, causing the lead screw to rotate and push the push-pull plate 325 to move backward along the connecting block chute 317 of the connecting block 316. The movement of the push-pull plate 325 drives the cylindrical pull rod 327 to slide within the elliptical chute block 333 and pulls the elliptical chute block 333, thereby pulling the rotating block 332 to rotate. The rotation of the rotating block 332 drives the auxiliary pedal body 331 to rotate forward and be parallel to the main pedal 1, realizing the deployment of the auxiliary pedal 33. After the auxiliary pedal 33 is fully deployed, the staff can safely stand on it for operation. When it is necessary to retract the auxiliary pedal 33, only the double-shaft motor 321 needs to be operated in reverse. The push-pull plate 325 will move forward, driving the cylindrical pull rod 327 and the rotating block 332 to rotate in the reverse direction, causing the auxiliary pedal body 331 to rotate backward;

[0038] While the push-pull plate 325 moves forward, the gear 313 at the bottom will rotate through the engagement with the rack 328, and then drive the gear 313 within the tapered groove 312 of the connecting plate 311 to rotate. The rotation of the gear 313 is transmitted to the second rack 342 of the support rod 34, causing the support rod body 341 to slide along the chute plate 314, realizing the telescoping of the support rod 34. The telescoping of the support rod 34 ensures the stability and safety of the auxiliary pedal 33 after deployment. When the auxiliary pedal 33 is fully deployed, the rubber blocks 345 of the support vertical rods 344 are in close contact with the ground, providing additional support force;

[0039] In the daily use of the construction elevator, the stability and safety of the auxiliary pedal 33 are crucial. To ensure this, the pedal control mechanism 3 is also equipped with a limit switch and a sensor system. The limit switch is installed at an appropriate position on the support rod 34. When the support rod 34 is fully extended or retracted to a predetermined position, the limit switch will automatically cut off the power supply to prevent mechanical damage caused by excessive telescoping. The sensor system is responsible for real-time monitoring of the load situation of the auxiliary pedal 33. Once it exceeds the preset safety range, the system will immediately issue an alarm and cut off the power supply of the double-shaft motor 321 through the control circuit to prevent accidents.

[0040] Working principle of the present invention: When the whole needs to be installed, first clamp the two groups of bottom steel keels 21 and top steel keels 25 on the concrete outer walls on both sides respectively. Then, adjust the length of the connecting rod 24 by rotating the fastening bolt 22 to ensure that the connecting mechanism 2 is firmly fixed on the concrete outer wall. The pressure gauge 23 is used to monitor the pressure borne by the connecting mechanism 2 to ensure the stability and safety of the whole system;

[0041] When the construction elevator is in use, the staff lower the auxiliary pedal 33. First, start the double-shaft motor 321. The rotation of the motor is transmitted to the lead screw 324 through the conical gear 322 and the second conical gear 323, causing the lead screw to rotate and push the push-pull plate 325 to move backward along the connecting block chute 317 of the connecting block 316. The movement of the push-pull plate 325 drives the cylindrical pull rod 327 to slide within the elliptical chute block 333 and pulls the elliptical chute block 333, thereby pulling the rotating block 332 to rotate. The rotation of the rotating block 332 drives the auxiliary pedal main body 331 to rotate forward and be parallel to the main pedal 1, realizing the unfolding of the auxiliary pedal 33. After the auxiliary pedal 33 is fully unfolded, the staff can safely stand on it for operation. When the auxiliary pedal 33 needs to be retracted, just operate the double-shaft motor 321 in reverse. The push-pull plate 325 will move forward, driving the cylindrical pull rod 327 and the rotating block 332 to rotate in the reverse direction, causing the auxiliary pedal main body 331 to rotate backward. While the push-pull plate 325 moves forward, the gear 313 at the bottom will rotate through the engagement with the rack 328, and then drive the gear 313 in the conical groove 312 of the connecting plate 311 to rotate. The rotation of the gear 313 is transmitted to the second rack 342 of the support rod 34, causing the support rod main body 341 to slide along the chute plate 314, realizing the telescoping of the support rod 34. The telescoping of the support rod 34 ensures the stability and safety of the auxiliary pedal 33 after unfolding. When the auxiliary pedal 33 is fully unfolded, the rubber block 345 of the support vertical rod 344 is in close contact with the ground, providing additional support force. In the daily use of the construction elevator, the stability and safety of the auxiliary pedal 33 are crucial. To ensure this, the pedal control mechanism 3 is also equipped with a limit switch and a sensor system. The limit switch is installed at an appropriate position on the support rod 34. When the support rod 34 is fully extended or retracted to a predetermined position, the limit switch will automatically cut off the power supply to prevent mechanical damage caused by excessive telescoping. The sensor system is responsible for real-time monitoring of the load condition of the auxiliary pedal 33. Once it exceeds the preset safety range, the system will immediately issue an alarm and cut off the power supply of the double-shaft motor 321 through the control circuit to prevent accidents.
