[0023] The utility model provides, for example Figure 1-5An elevator with a bottom frame safety maintenance component is shown, including an elevator shaft 1. A guide rail 12 is installed on the inner side of the elevator shaft 1. A car 13 is installed in the elevator shaft 1 via the guide rail 12. When the car 13 moves up and down along the guide rail 12, the traveling cable 5 located at the lower end of the car 13 moves with it. A counterweight rail 7 is provided in the inner side of the elevator shaft 1. A counterweight frame 10 is installed in the inner side of the counterweight rail 7. A counterweight block B14 and multiple counterweight blocks A11 are engaged in the inner side of the counterweight frame 10. Multiple insertion holes 23 are distributed in the inner side of the counterweight frame 10. A slot 22 is provided in the inner side of the counterweight frame 10. Multiple ball bearings 21 are sleeved in the inner side of the slot 22. An auxiliary wheel 20 is sleeved in the inner side of the slot 22. A connecting rod 17 is fixed at one end of the auxiliary wheel 20, and a roller 16 is fixed at the other end of the connecting rod 17.

[0024] In the elevator shaft 1, the main unit 3 drives the car 13 and counterweight 10 to move up and down via steel cables. The car 13 and counterweight 10 are connected by a compensating chain 6 to ensure balance between them. The speed governor 2 monitors the elevator speed to ensure timely braking in case of overspeed and maintain safety. The control cabinet 4 coordinates the operation of various components and receives signals from the traveling cable 5 to ensure normal elevator operation. The hall door 8 automatically opens when the car 13 stops to ensure safe entry and exit for passengers. The buffer 9 plays a buffering role at extreme positions to protect the car 13 from impact. Finally, the bottom frame assembly 24 safety maintenance component further enhances the overall safety of the system, detects faults in a timely manner and automatically alarms to ensure the safety and stability of the elevator during operation.

[0025] like Figure 1 and Figure 2 As shown, a speed limiter 2 is installed at the upper end of the elevator shaft 1 at a certain position. A main unit 3 is installed at the middle position of the upper end of the elevator shaft 1. A control cabinet 4 is installed at the right side of the upper end of the elevator shaft 1. A hall door 8 is installed at the front end of the elevator shaft 1. A bottom frame assembly 24 is installed on the left and right sides of the front end of the hall door 8. A buffer 9 is installed at the bottom of the elevator shaft 1. The buffer 9 absorbs the energy generated by the impact when the car 13 descends rapidly. The two ends of the compensation chain 6 are connected to the counterweight frame 10 and the car 13 respectively. The compensation chain 6 adjusts the balance between the counterweight frame 10 and the car 13 to ensure that the weight of both can be kept within a reasonable range. Multiple counterweight blocks A11 are provided. The counterweight blocks A11 are locked inside the counterweight frame 10. The counterweight blocks B14 are locked inside the uppermost position of the counterweight frame 10.

[0026] When the counterweight frame 10 moves up and down, the roller 16 rotates along the inner wall of the counterweight track 7. At the same time, the rotation of the roller 16 drives the auxiliary wheel 20 to rotate in the slot 22. The auxiliary wheel 20 rotates in contact with the ball bearing 21. Thus, when the roller 16 moves along the counterweight track 7, the rotation of the auxiliary wheel 20 can assist the roller 16, making the counterweight frame 10 more flexible when moving up and down along the counterweight track 7.

[0027] like Figure 4 and Figure 5 As shown, when the counterweight B14 is engaged in the internal position of the counterweight frame 10, the gear column 18 is inserted into the insertion hole 23. The adjusting knob 15 drives the gear plate 19 to rotate. The gear structure of the gear plate 19 is engaged with the gear structure of the gear column 18. The rotation of the gear plate 19 causes the gear column 18 to move. When the counterweight frame 10 moves, the fixed roller 16 moves along the counterweight track 7. The rotation of the roller 16 causes the auxiliary wheel 20 to rotate in the internal position of the slot 22.

[0028] The counterweight consists of multiple counterweight blocks A11 and one counterweight block B14. When adjusting the weight of the counterweight frame 10, the corresponding number of counterweight blocks A11 are first slidably engaged in the internal position of the counterweight frame 10. At the same time, multiple insertion holes 23 are distributed on the inner side of the counterweight frame 10. After the counterweight blocks A11 are installed, the counterweight block B14 is finally installed at the top position of the counterweight blocks A11. Rotating the adjustment knob 15 causes the gear plate 19 to rotate. The gear structure of the gear plate 19 is engaged with the gear column 18. The rotation of the gear plate 19 causes the gear column 18 to move and be inserted into the insertion hole 23. This completes the weight adjustment of the counterweight frame 10. The weight adjustment of the counterweight frame 10 can be completed quickly in this way.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
