DETAILED DESCRIPTION

[0025] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0026] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation of the present invention.

[0027] like Figures 1 to 4As shown, an elevator settlement shock absorption device includes a settlement detection unit 1 and a shock absorption connection component 2; Embodiment 1: The settlement detection unit 1 includes a first detection component 11 and a second detection component, the first detection component 11 is composed of an annular pipe 111 surrounding the elevator shaft and an elastic force detector 112 located below it, and the annular pipe 111 is filled with a specific liquid for detecting settlement through liquid level changes. The second detection component is composed of a laser generator and a reflection collection plate, which is installed outside the elevator shaft to monitor the settlement changes in the vertical direction; and the laser generator is installed on the same horizontal plane outside the elevator shaft 5, and the laser generator periodically emits a light beam to the laser reflection collection plate next to the elevator shaft 5.

[0028] Furthermore, at least four liquid level detection points for calculating the inclination angle after the wellbore settles are provided on the annular pipe 111; 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 the comprehensiveness and accuracy of the measurement.

[0029] The shock-absorbing connection component 2 is assembled between the additional elevator corridor 3 and the old building body 4; the shock-absorbing connection component 2 adopts a U-shaped settlement adjustment device 21 and a connection shock-absorbing device 22. The U-shaped settlement adjustment device 21 connects the additional elevator corridor 3 and the old building body 4 through bolts. The connection shock-absorbing device includes multiple elastic shock-absorbing elements, which are installed on the old building and connected to the elevator corridor to provide a shock-absorbing effect.

[0030] Furthermore, the connecting shock absorbing device 22 is provided with a plurality of elastic shock absorbing elements 221 and a connecting end 222, and the plurality of elastic shock absorbing elements 221 are assembled on the connecting end 222 connected to the additional elevator corridor 3. The elastic shock absorbing element 221 is usually made of a material with high elasticity and restoring force, such as rubber, spring or a combination of the two. It can absorb and disperse the vibration and impact force from the elevator corridor, thereby protecting the old building body 4 from damage. When the elevator corridor is subjected to external vibration, the elastic shock absorbing element 221 will begin to deform, absorb and disperse the energy. The connecting end 222 ensures that the load of the additional elevator corridor 3 can be safely transferred to the structure of the old building body 4; significantly improving the stability of the entire structure.

[0031] The data processing module is connected to the settlement detection unit 1 by electrical signals, and is used to receive data from the settlement detection unit 1, and calculate the relative settlement value of each floor corridor of the elevator shaft 5 and the old building floor, as well as the tilt and torsion angle. The data processing module has powerful data processing and analysis capabilities, and can realize intelligent processing and analysis of settlement data to improve monitoring efficiency. In addition, it can monitor the settlement of the foundation in real time, and issue early warning information in time when abnormal settlement is found or potential settlement risks are predicted, so as to take timely measures to prevent accidents.

[0032] A method for monitoring elevator settlement: S1. Install settlement detection unit 1 at the key connection point between the elevator and the old building.

[0033] S2. Regularly collect settlement data through the data processing module, and calculate the relative settlement value and inclination and torsion angle of the elevator corridor on each floor and the floor slab on the same floor of the old building main body.

[0034] S3. Compare the monitoring data with the preset safety threshold and issue an early warning when the threshold is exceeded.

[0035] Example 2: Enhanced sedimentation detection and regulation system Device Description: This embodiment is an upgrade on the basic device, which enhances the accuracy of settlement detection and the flexibility of adjustment: Among them, at least four liquid level detection points are added to the annular pipe 111 of the first detection component 11 of the settlement detection unit 1, and each detection point is equipped with a water level detection device, which improves the accuracy of settlement measurement and the accuracy of inclination angle calculation.

The height difference between the elevator corridor 3 and the old building body 4 can be adjusted by adjusting the position of the bolts on the multiple bolt holes 211; appropriate settlement adjustment can reduce the structural stress concentration and fatigue damage caused by the height difference, thereby extending 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 bolts to be installed and adjusted at different positions; since the number and arrangement of the bolt holes 211 can be customized according to actual needs, the U-shaped settlement adjustment device 21 provides a high degree of accuracy and flexibility.

[0037] An elevator settlement monitoring method: When installing an enhanced settlement detection unit, ensure that each key connection point has accurate settlement monitoring. The data processing module not only collects settlement data, but also analyzes the tilt and torsion angles in real time and stores them in an elevator settlement monitoring database connected to the electrical signal of the storage data processing module. When settlement or deformation is detected beyond the safety range, an early warning is automatically triggered, and a prompt is given to balance the height difference by adjusting the bolt position of the U-shaped settlement adjustment device 21.

[0038] Example 3: Comprehensive elevator settlement management solution This embodiment provides a comprehensive elevator settlement management solution, combining advanced settlement detection, intelligent early warning and automatic adjustment technologies: The settlement detection unit 1 uses high-precision laser ranging and liquid level sensing technology to achieve three-dimensional settlement monitoring. The shock-absorbing connection component 2 integrates an intelligent control system, which can adjust the height of the U-shaped settlement adjustment device 21 according to the instructions of the data processing module to respond to settlement changes. Intelligent early warning and decision support system: Based on historical settlement data and real-time monitoring results, it automatically evaluates the safety status of the elevator and puts forward maintenance suggestions or early warnings.

[0039] A method for monitoring elevator settlement: implement comprehensive settlement monitoring, covering all key connection points of the elevator to ensure the accuracy and timeliness of the data. The intelligent early warning system monitors the settlement data in real time, compares it with the preset threshold, automatically triggers the early warning and recommends maintenance measures. Based on the historical data in the elevator settlement monitoring database, trend analysis and risk assessment are carried out to provide decision support for long-term maintenance and management. When necessary, the intelligent control system automatically adjusts the shock-absorbing connection component 2 to reduce or eliminate the height difference and deformation caused by settlement.

[0040] An elevator settlement monitoring method comprises the following steps: S1. Monitor the settlement value of the elevator corridor 3 and the floor slab of the old building main body 4 on each floor of the elevator shaft 5 through the settlement detection unit 1 and the water level detection device, and install the settlement detection unit 1 at the key connection point between the elevator and the old building main body 4; S2.
