Description

Technical Field

[0001] This invention relates to the field of elevator retrofitting technology, specifically to an integrated elevator system for retrofitting existing buildings. Background Technology

[0002] The installation of elevators in older residential communities is a response to my country's aging population trend and is of great significance for improving the living conditions of residents in these communities, including the elderly and disabled. In recent years, the work of installing 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 its compatibility with the existing building structure, including fire safety and other requirements.

[0003] Chinese patent CN116675088B discloses an attached elevator installation method. The solution includes a shaft structure made of steel, which includes a fixing part that is fixed to the top and side of the existing building during installation. The fixing part includes a side wall connector, one end of which is fixedly connected to the side of the shaft structure facing the existing building. The fixing part is fixed to the concrete components of the existing building through an anchoring structure. When the installation is completed, the shaft structure is directly attached to the outer surface of the existing building to seal the bottom opening of the shaft structure.

[0004] As mentioned in the application above, currently, elevator shafts added to existing buildings are typically located on the exterior of the building and fixed to it via anchoring structures, with the elevator installed inside the shaft for use. However, this external shaft design presents certain safety hazards and limitations. First, because the shaft is located on the exterior of the building, it is susceptible to external factors, such as vehicle collisions or other unexpected impacts, increasing the risk of damage. Second, when the elevator malfunctions, the smooth exterior walls of the shaft cannot provide effective climbing or walking paths for rescuers, potentially hindering emergency rescue operations and further affecting rescue efficiency and safety. Therefore, when adding elevators, these potential risks must be fully considered, and appropriate design and protective measures must be taken to improve safety and convenience.

Second, in the event of an elevator malfunction, the fire escape route provides a convenient passage for rescue personnel, allowing them to walk or climb along the shaft to quickly carry out emergency rescue operations. In addition, the fire escape route connects to the staircases of the existing building, serving as an additional escape route, overcoming the problem of narrow and dark stairwells in old residential areas, which makes it difficult to escape in the event of fires or other disasters.

Next, elevator operation data is acquired, generating an elevator operation stability coefficient, and then generating a second elevator speed command based on that coefficient. Finally, a combined elevator speed command is generated based on both the first and second speed commands, and the elevator speed is controlled accordingly. This comprehensive approach, considering both the shaft status coefficient and the car operation stability coefficient, ensures stable and safe elevator operation. Attached Figure Description

[0059] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0060] Example 1

[0061] Please see Figures 1-3 This invention provides a technical solution: an integrated elevator device for retrofitting existing buildings, comprising:

[0062] Shaft 1 is formed by at least four columns 15 and outer protective plates 16. The columns 15 are connected to each other by crossbars, and the outer protective plates 16 are fixed to the columns 15 by fixing blocks and bolts. The outer protective plates 16 are designed to be detachable and are concave. Two outer protective plates 16 together form a rectangular frame structure.

[0063] An elevator is installed inside shaft 1;

[0064] The elevator consists of a car 101 and a traction mechanism 102;

[0065] The car 101 is slidably installed inside the hoistway 1;

[0066] The traction mechanism 102 is used to drive the car 101 to move vertically up and down along the hoistway 1. The traction mechanism 102 is located at the top of the hoistway 1. The traction mechanism 102 is a winch, and a traction rope 103 is installed on it to connect with the car 101.

[0067] Fire passage 2 is cantilevered and fixed around the shaft 1. Fire passage 2 is connected to the existing staircase of the building. Fire passage 2 consists of several first stair platforms 31, several second stair platforms 32 and several stair sections 33. The several first stair platforms 31 and several second stair platforms 32 are staggered on the outer wall of the shaft 1. The first stair platforms 31 and the second stair platforms 32 are staggered relative to each other. The several stair sections 33 are connected between two adjacent first stair platforms 31 and second stair platforms 32.

[0068] Glass curtain wall 3 is fixed to the outside of fire escape 2.

[0069] The column 15 is connected to several cantilever beams 13 at equal intervals by tenon and mortise joints. The cantilever beams 13 are located on the lower surface of several first stair platforms 31 and second stair platforms 32, and are welded and fixed to the first stair platforms 31 and second stair platforms 32.

[0070] A fixing seat 14 is welded to one end of the cantilever beam 13 near the existing building. The fixing seat 14 has an installation hole and is fixedly connected to the outer wall of the existing building through the installation hole and expansion bolts, so that the shaft 1, fire passage 2 and the existing building are integrated.

[0071] The glass curtain wall 3 has a concave structure. The side of the glass curtain wall 3 that is opposite to the existing building does not have a glass curtain wall 3. The top of the glass curtain wall 3 is covered with a cap 31.

[0072] The top of the shaft 1 is provided with an equipment room 11, which is used to install the traction mechanism 102. The outer wall of the shaft 1, which faces the existing building, is provided with several electric doors 12 that can be opened and closed.

[0073] In this embodiment, a fire escape 2 is provided and cantilevered and fixed around the shaft 1. The fire escape 2 provides collision protection for the shaft 1 located on the outside of the building. In the event of an elevator malfunction in the shaft 1, emergency rescue can be carried out by walking and climbing through the fire escape 2. Finally, the fire escape 2 is connected to the existing staircase of the building and can be used as a fire escape 2 for the existing building, thereby overcoming the problem of narrow and dark stairwells in old residential buildings, which makes it difficult to escape in the event of a disaster.

[0074] Example 2

[0075] Based on Example 1, this embodiment further addresses how to effectively control the elevator's operating speed within the shaft 1 when the shaft 1 is located outside the building, resulting in the shaft 1 being separated from the building, in order to ensure the stability of the elevator's operation. By optimizing the control method, it ensures that the elevator in the external shaft 1 can maintain smooth and efficient speed regulation when operating independently, avoiding shaking or instability during operation.

[0076] Please see Figures 1-4 This implementation adds a movement speed control unit based on the above embodiments;

[0077] The speed control unit is installed on the car 101 and includes:

[0078] The first data acquisition module collects wellbore status data.

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

[0080] Specifically, the height of the shaft directly affects the acceleration and deceleration phases of the elevator. A higher shaft usually allows the elevator to be designed for a higher operating speed. Therefore, the higher the shaft 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 using a laser measuring instrument or a total station.

[0082] The hoistway-car clearance ratio refers to the ratio of the area of ​​the car 101 to the clearance area. The clearance area is calculated by subtracting the cross-sectional area of ​​the car 101 from the cross-sectional area of ​​the hoistway 1. It should be noted that a larger hoistway-car clearance ratio indicates a smaller clearance between the car and the hoistway, which increases the air resistance between the car 101 and the inner wall of the hoistway 1, thereby reducing the elevator's operating speed. Conversely, a smaller hoistway-car clearance ratio has the opposite effect.

[0083] The first data analysis module acquires hoistway status data information, generates hoistway status coefficients based on the hoistway status data information, and generates the first elevator speed command based on the hoistway status coefficients.

[0084] Methods for generating wellbore state coefficients based on wellbore state data include:

[0085]

[0086] In the formula, JDxs is the hoistway condition coefficient, JT is the hoistway height, CLd is the hoistway verticality, and JXB is the hoistway-to-car ratio. and These are the weighting coefficients. and Greater than 0;

[0087] It should be noted that the weighting coefficient is a specific value obtained by quantifying each data point to facilitate subsequent comparison. The size of the weighting coefficient depends on the number of comprehensive parameters and the weighting coefficient initially set by those skilled in the art for each set of comprehensive parameters.

[0088] It should be noted that the larger the shaft condition coefficient, the greater the elevator's speed can be, and vice versa.

[0089] Methods for generating the first elevator speed command based on the shaft condition coefficient include:

[0090] The first elevator speed command includes the first-level shaft speed command, the second-level shaft speed command, and the third-level shaft speed command, and the speed of movement of the first-level shaft speed command, the second-level shaft speed command, and the third-level shaft speed command increases in sequence;

[0091] Preset wellbore state coefficient gradient thresholds, JD1 and JD2, where JD1 < JD2;

[0092] When JDxs < JD1, a level 3 hoistway movement command is generated;

[0093] When JD1≤JDxs<JD2, a secondary shaft movement speed command is generated;

[0094] When JDxs > JD2, a first-level wellbore movement speed command is generated.

[0095] The second data acquisition module collects elevator operation data.

[0096] The elevator operation data 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 elevator speed, and vice versa. The greater the vibration amplitude of the car 101, the lower the elevator speed, and vice versa. The greater the vibration amplitude of the traction rope 103, the lower the elevator speed, and vice versa.

[0098] The vibration amplitude of the car 101 and the vibration amplitude of the traction rope 103 can be acquired by 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] The second data analysis module acquires elevator operation data information, generates an elevator operation stability coefficient based on the elevator operation data information, and generates a second elevator speed command based on the elevator operation stability coefficient.

[0100] Methods for generating elevator stability coefficients based on elevator operation data include:

[0101] DTxs=β1×Jt+β2×Jz+β3×QYSz;

[0102] In the formula, DTxs is the elevator running stability coefficient, Jt is the weight of the car 101, Jz is the vibration amplitude of the car 101, QYSz is the vibration amplitude of the traction rope 103, β1, β2 and β3 are weighting coefficients, and β1, β2 and β3 are greater than 0.

[0103] It should be noted that the weighting coefficient is a specific value obtained by quantifying each data point to facilitate subsequent comparison. The size of the weighting coefficient depends on the number of comprehensive parameters and the weighting coefficient initially set by those skilled in the art for each set of comprehensive parameters.

[0104] Methods for generating a second elevator speed command based on the elevator's operational stability coefficient include:

[0105] The second elevator speed command includes the first-level car speed command, the second-level car speed command, and the third-level car speed command, and the moving speed of the first-level car speed command, the second-level car speed command, and the third-level car speed command decreases in sequence.

[0106] Preset elevator operation stability coefficient thresholds DT1 and DT2, where DT1 < DT2;

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

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

[0109] When JDxs > DT2, a three-level car speed command is generated.

[0110] The comprehensive analysis module generates a comprehensive elevator speed command based on the first elevator speed command and the second elevator speed command, and controls the elevator running speed based on the comprehensive elevator speed command.

[0111] The method for generating a combined elevator speed command based on the first elevator speed command and the second elevator speed command includes:

[0112] The integrated elevator speed command includes the speed commands for the first-level elevator, the second-level elevator, and the third-level elevator, with the speed commands decreasing sequentially from first-level to third-level.

[0113] When the elevator has both a first-level shaft speed command and a first-level car speed command, a first-level elevator speed command is generated.

[0114] When the elevator simultaneously has: a first-level shaft speed command and a second-level car speed command, a second-level shaft speed command and a second-level car speed command, or a second-level shaft speed command and a first-level car speed command, then a second-level elevator speed command is generated.

[0115] When the elevator simultaneously has: a three-level shaft speed command and a one-level car speed command, a three-level shaft speed command and a two-level car speed command, a three-level shaft speed command and a three-level car speed command, a one-level shaft speed command and a three-level car speed command, and a two-level shaft speed command and a three-level car speed command, then a three-level elevator speed command is generated.

[0116] In this embodiment, when controlling the speed of an elevator added to an existing building, the process first considers the elevator shaft, i.e., acquiring shaft state data, generating a shaft state coefficient based on the shaft state data, and generating a first elevator speed command based on the shaft state coefficient. Then, the process acquires elevator operation data, generates an elevator operation stability coefficient based on the elevator operation data, generates a second elevator speed command based on the elevator operation stability coefficient, and finally generates a comprehensive elevator speed command based on the first and second elevator speed commands. The elevator speed is controlled based on the comprehensive elevator speed command. This process comprehensively considers both the shaft state coefficient and the car operation stability coefficient, taking into account the elevator speed requirements from multiple perspectives, thus ensuring the stable and safe operation of the elevator.
