In recent years, the installation of elevators has been actively promoted and has achieved positive results. However, when installing elevators in existing buildings, it is usually necessary to consider not only the design and installation of the elevator itself, but also the compatibility with the existing building structure, including fire protection, safety and other requirements.

The fire escape passage 2 consists of a plurality of first staircase platforms 31, a plurality of second staircase platforms 32 and a plurality of stair sections 33. The plurality of first staircase platforms 31 and the plurality of second staircase platforms 32 are staggered on the outer wall of the shaft 1. The first staircase platforms 31 and the second staircase platforms 32 are relatively staggered. A plurality of stair sections 33 are connected between two adjacent first staircase platforms 31 and second staircase platforms 32.

[0068] A glass curtain wall 3 is fixed on the outside of the fire passage 2.

[0069] A plurality of cantilever beams 13 are connected with mortise and tenon joints at equal intervals on the columns 15 , and the plurality of cantilever beams 13 are all located on the lower surfaces of the plurality of first staircase platforms 31 and the second staircase platforms 32 , and are welded and fixed to the first staircase platforms 31 and the second staircase platforms 32 .

[0070] A fixing seat 14 is welded to one end of the cantilever beam 13 close to the existing building. The fixing seat 14 is provided with a mounting hole. The fixing seat 14 is fixedly connected to the outer wall of the existing building through the mounting hole and expansion bolts, so that the well 1, the fire passage 2 and the existing building are integrated.

[0071] The glass curtain wall 3 is a concave structure. The side of the glass curtain wall 3 corresponding to the existing building is not provided with a glass curtain wall 3. A cover 31 is provided at the top of the glass curtain wall 3.

[0073] In this embodiment, a fire passage 2 is provided, and the fire passage 2 is cantilevered and fixed around the shaft 1. Through the provision of the fire passage 2, the shaft 1 arranged outside the building can be protected from collision.

[0074] Example 2

[0075] Based on Example 1, this embodiment further solves the problem of how to effectively control the running speed of the elevator in the shaft 1 to ensure the stability of the elevator operation when the shaft 1 is separated from the building due to the shaft 1 being set outside the building. By optimizing the control method, it is ensured that the elevator in the external shaft 1 can still maintain smooth and efficient speed regulation during independent operation, avoiding shaking or instability during operation.

[0076] See also Figure 1-Figure 4 , this embodiment adds a speed control unit on the basis of the above embodiment;

[0077] The speed control unit is arranged on the car 101, and the speed control unit comprises:

[0078] A first data acquisition module collects shaft status data information;

[0079] The hoistway status data information includes hoistway height, hoistway verticality and hoistway-car clearance ratio;

[0080] Specifically, the height of the hoistway directly affects the acceleration and deceleration stages of the elevator. A higher hoistway usually allows the elevator to be designed for a higher operating speed. Therefore, the higher the hoistway height, the faster the elevator moves, and vice versa.

[0081] The greater the verticality of the shaft, the faster the elevator moves, and vice versa. The verticality of the shaft can be measured by a laser measuring instrument or a total station.

[0082] The shaft-car gap ratio refers to the ratio of the area of ​​the car 101 to the gap area, wherein the gap area refers to the gap area obtained by subtracting the cross-sectional area of ​​the car 101 from the cross-sectional area of ​​the shaft 1. It should be noted that the larger the shaft-car gap ratio, the smaller the gap between the car and the shaft, which will increase the air resistance between the car 101 and the inner wall of the shaft 1, thereby reducing the elevator running speed, and vice versa.

[0083] A first data analysis module acquires shaft state data information, generates a shaft state coefficient based on the shaft state data information, and generates a first elevator speed instruction according to the shaft state coefficient;

[0087] It should be noted that the size of the weight coefficient is a specific value obtained by quantifying each data, which is convenient for subsequent comparison. The size of the weight coefficient depends on the number of comprehensive parameters and the preliminary setting of the corresponding weight coefficient for each group of comprehensive parameters by those skilled in the art;

[0088] It should be noted that the greater the shaft state coefficient, the greater the elevator moving speed can be, and vice versa.

[0089] The method for generating a first elevator speed instruction according to a shaft state coefficient includes:

[0090] The first elevator speed command includes a first-level shaft speed command, a second-level shaft speed command and a third-level shaft speed command, and the moving speeds of the first-level shaft speed command, the second-level shaft speed command and the third-level shaft speed command increase in sequence;

[0096] The elevator operation data information includes the weight of the car 101, the vibration amplitude of the car 101 and the vibration amplitude of the traction rope 103;

[0097] It should be noted that the greater the weight of the car 101, the lower the moving speed of the elevator, and vice versa; the greater the vibration amplitude of the car 101, the lower the moving speed of the elevator, and vice versa; the greater the vibration amplitude of the traction rope 103, the lower the moving speed of the elevator, and vice versa;

[0098] The vibration amplitude of the car 101 and the vibration amplitude of the traction rope 103 can be acquired by using an acceleration sensor. The acceleration sensor can accurately measure the acceleration changes of the car 101 and the traction rope 103 during operation, and then calculate the vibration amplitude.

[0099] A second data analysis module obtains elevator operation data information, generates an elevator operation stability coefficient based on the elevator operation data information, and generates a second elevator movement speed instruction according to the elevator operation stability coefficient;

[0100] The method for generating an elevator operation stability coefficient based on elevator operation data information includes:

[0101] DTxs=β1×Jt+β2×Jz+β3×QYSz;

[0103] It should be noted that the size of the weight coefficient is a specific value obtained by quantifying each data, which is convenient for subsequent comparison. The size of the weight coefficient depends on the number of comprehensive parameters and the preliminary setting of the corresponding weight coefficient for each group of comprehensive parameters by those skilled in the art;

[0104] The method for generating a second elevator speed instruction according to the elevator operation stability coefficient includes:

[0105] The second elevator speed command includes a first-level car speed command, a second-level car speed command and a third-level car speed command, and the moving speeds of the first-level car speed command, the second-level car speed command and the third-level car speed command decrease in sequence;

[0106] The elevator operation stability coefficient thresholds DT1 and DT2 are preset, and DT1<DT2;

[0107] When JDxs<DT1, a first-level car speed instruction is generated;

[0108] When DT1≤JDxs<DT2, a secondary car speed command is generated;
