DETAILED DESCRIPTION

[0037] The technical solutions of the embodiments of the present application will be explained and described below in conjunction with the drawings of the embodiments of the present application, but the following embodiments are only preferred embodiments of the present application, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0038] In the following description, the appearance of terms such as "inner", "outer", "upper", "lower", "left", "right", etc. indicating the orientation or position relationship is only for the convenience of describing the embodiments and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0039] As Figs. 1 to 4As shown, an elevator subsidence damping device includes a subsidence detection unit 1 and a damping connection assembly 2. Embodiment 1: The subsidence detection unit 1 includes a first detection assembly 11 and a second detection assembly. The first detection assembly 11 is composed of an annular pipe 111 surrounding the added elevator shaft and an elastic detector 112 located below it. The annular pipe 111 is filled with a specific liquid for detecting subsidence by changes in liquid level. The second detection assembly is composed of a laser generator and a reflective collection plate, installed outside the elevator shaft, for monitoring vertical subsidence changes. The laser generator is installed on the same horizontal plane outside the added elevator shaft 5. The laser generator regularly emits a light beam onto the laser reflective collection plate beside the added elevator shaft 5.

[0040] Further, the annular pipe 111 is provided with at least four liquid level detection points for calculating the inclination angle of the shaft after subsidence. The liquid level detection points are equipped with water level detection devices. The liquid level detection points are evenly distributed around the annular pipe 111 to ensure comprehensive and accurate measurement.

[0041] The damping connection assembly 2 is installed between the added elevator corridor 3 and the old building main body 4. The damping connection assembly 2 uses a U-shaped subsidence adjustment device 21 and a connection damping device 22. The U-shaped subsidence adjustment device 21 connects the added elevator corridor 3 and the old building main body 4 through bolts. The connection damping device contains multiple elastic damping elements, installed on the old building, connected to the elevator corridor, providing damping effect.

[0042] Further, the connection damping device 22 is provided with multiple elastic damping elements 221 and connection ends 222. The multiple elastic damping elements 221 are installed on the connection ends 222 connected to the added elevator corridor 3. The elastic damping elements 221 are usually made of materials with high elasticity and restoring force, such as rubber, springs, or a combination of both. They can absorb and disperse the vibration and impact force from the elevator corridor, thereby protecting the old building main body 4 from damage. When the elevator corridor is subjected to external vibration, the elastic damping elements 221 will begin to deform, absorbing and dispersing the energy. The connection ends 222 ensure that the load of the added elevator corridor 3 can be safely transmitted to the structure of the old building main body 4, significantly improving the stability of the entire structure.

[0043] The data processing module is connected to the subsidence detection unit 1 through electrical signals, used to receive data from the subsidence detection unit 1, and calculate the relative subsidence value of each floor corridor of the added elevator shaft 5 and the old building floor, as well as the inclination and torsion angles. The data processing module has strong data processing and analysis capabilities, enabling intelligent processing and analysis of subsidence data, improving monitoring efficiency. It can also monitor the subsidence of the foundation in real time and issue early warning information when abnormal subsidence or potential subsidence risks are detected, so that timely measures can be taken to prevent accidents.

[0044] An elevator settlement monitoring method:

[0045] S1, install a settlement detection unit 1 at the key connection points of the elevator and the old building.

[0046] S2, collect settlement data regularly through the data processing module, calculate the relative settlement value and the inclination and torsion angle of each floor of the elevator corridor and the same floor of the main body of the old building.

[0047] S3, compare the monitoring data with the preset safety threshold, and issue a warning when the threshold is exceeded.

[0048] Example 2: Enhanced settlement detection and adjustment system

[0049] Device description: This embodiment upgrades the basic device, enhancing the accuracy of settlement detection and the flexibility of adjustment:

[0050] Among them, at least four liquid level detection points are added to the annular pipeline 111 of the first detection assembly 11 of the settlement detection unit 1, and a water level detection device is provided at each detection point, which improves the accuracy of settlement measurement and the accuracy of inclination angle calculation.

[0051] The U-shaped settlement adjustment device 21 in the shock absorption connection assembly 2 is provided with longitudinal multiple bolt holes 211 on both sides, and the height difference between the added elevator corridor 3 and the main body of the old building 4 is adjusted by adjusting the position of the adjusting bolt in the multiple bolt holes 211; Proper settlement adjustment can reduce structural stress concentration and fatigue damage caused by height difference, thereby prolonging the service life of the elevator corridor and the building body; The design of the U-shaped settlement adjustment device 21 makes maintenance and adjustment relatively simple and convenient. Multiple bolt holes 211 allow the bolt to be installed and adjusted at different positions; Because the number and arrangement of bolt holes 211 can be customized according to actual needs, the U-shaped settlement adjustment device 21 provides high accuracy and flexibility.

[0052] An elevator settlement monitoring method: When installing an enhanced settlement detection unit, ensure that each key connection point has accurate settlement monitoring. Among them, the data processing module not only collects settlement data, but also analyzes the inclination and torsion angle in real time, and stores it in the elevator settlement monitoring database connected with the storage data processing module electrical signal. When the settlement or deformation exceeds the safety range, an automatic warning is triggered, and it is suggested to balance the height difference by adjusting the position of the bolt of the U-shaped settlement adjustment device 21.

[0053] Example 3: Comprehensive elevator settlement management solution

[0054] This embodiment provides a comprehensive elevator settlement management solution, combining advanced settlement detection, intelligent warning and automatic adjustment technology:

[0055] The settlement detection unit 1 adopts high-precision laser ranging and liquid level sensing technology to realize three-dimensional settlement monitoring. The shock-absorbing connection assembly 2 integrates an intelligent control system, which can adjust the height of the U-shaped settlement adjusting device 21 according to the instructions of the data processing module to respond to settlement changes. The intelligent early warning and decision support system automatically evaluates the safety state of the elevator based on historical settlement data and real-time monitoring results, and proposes maintenance recommendations or warnings.

[0056] An elevator settlement monitoring method: comprehensive settlement monitoring covers all key connection points of the elevator, ensuring the accuracy and timeliness of the data. The intelligent early warning system monitors settlement data in real time, compares it with the preset threshold, automatically triggers an early warning and suggests maintenance measures. Based on historical data in the elevator settlement monitoring database, trend analysis and risk assessment are performed to provide decision support for long-term maintenance and management. When needed, the intelligent control system automatically adjusts the shock-absorbing connection assembly 2 to reduce or eliminate the height difference and deformation caused by settlement.

[0057] An elevator settlement monitoring method, comprising the following steps:

[0058] S1, monitor the settlement value of each floor of the elevator and the old building main body 4 floor of the elevator corridor 3 added to the elevator shaft 5 by the settlement detection unit 1 and the water level detection device, and install the settlement detection unit 1 at the key connection points of the elevator and the old building main body 4;

[0059] S2, periodically collect data of the settlement detection unit 1 by the data processing module to obtain settlement values of the elevator and the building main body in various directions; according to the collected data, calculate the relative settlement value of each floor of the elevator and the old building main body 4 floor of the elevator corridor 3 added, and the inclination and torsion angle;

[0060] S3, compare the settlement monitoring data with the preset safety threshold, and issue a warning signal when the settlement value or inclination and torsion angle exceeds the safety threshold.

[0061] An elevator settlement monitoring method further comprises adjusting the shock-absorbing connection assembly 2 to eliminate the height difference between the elevator corridor 3 added and the old building main body 4 floor.

[0062] For continuous monitoring, the elevator settlement monitoring method establishes an elevator settlement monitoring database to store historical settlement monitoring data for subsequent analysis and decision-making.

Those skilled in the art should understand that the present application includes but is not limited to the contents described in the above specific embodiments and the drawings.
