Problems solved by technology

Since the main body of the elevator and the existing building belong to two completely different structures with different foundations, different constructions, and different ages, the installation of an elevator outside the existing building may be due to differences in materials, foundations, construction methods, and construction years. The reason is thermal deformation of metal materials, elastic-plastic deformation, and uneven settlement between the two foundations, which will lead to elevator operation failure, and even damage to the existing building structure, cracking of the wall and other safety accidents
At present, due to the short application time of adding elevators and the imperfect collection and processing of relevant data, there is a lack of data accumulation in the design of adding elevators
For example, at present, the steel structure main body of the elevator is generally designed with equal strength, which is likely to cause insufficient safety strength or excess margin, and cannot consider the influence of car position, operating season, operating conditions, and thermal deformation on the settlement of the elevator steel structure. Therefore, it is of great significance to take technical measures to monitor and analyze the data monitoring and analysis of elevator installation in existing buildings as soon as possible, which is of great significance for evaluating the safety of elevator design, installation, use and maintenance.
[0005] Under the existing technology, data collection generally adopts switch sensors installed between the existing building and the main body of the elevator, and elevator components such as shafts, machine rooms, guide rails, pits, and cars, which can only realize the setting of threshold signals. On and off control, it is difficult to realize the analysis and utilization of data
Another problem is that the existing technology to monitor the settlement of the elevator structure is not related to the operating conditions of the elevator, and this is one of the important reasons that affect the settlement and deformation of the main structure of the elevator.

Embodiment 1

[0041] In one or more embodiments, an elevator settlement data acquisition system is disclosed, referring to figure 1 ,include:

[0042] (1) the position coding device 3 that is fixed on the existing building 1, the position coding device 3 cooperates with the reading head that is arranged on the elevator car 6 setting positions, to record the operation of the elevator car 6 in the vertical direction, The absolute position data of the parking level (i.e. door opening 8);

[0043] In this embodiment, the position encoding device 3 is connected to the connecting piece 5, and the connecting piece 5 is respectively fixed on the upper and lower ends of the building. In terms of specific design, the connecting piece 5 extends into the interior of the main body of the steel structure of the elevator through the holes provided on the main body of the steel structure of the elevator, so as to be suitable for contacting with the reading head of the elevator.

[0044] refer to figure ...

Embodiment 2

[0067] In one or more embodiments, an elevator retrofit system is disclosed, including the elevator retrofit settlement data collection system described in Embodiment 1.

Embodiment 3

[0069] In one or more embodiments, a method for collecting elevator settlement data is disclosed, including the following process:

[0070] (1) Elevator initialization, the elevator control system performs self-learning based on LPG, obtains the absolute value distance signal of the elevator shaft, and sets a fixed node 7 (anchor node) with communication function at a predetermined position (such as the upper and lower end stations of the elevator, but not limited to) ), the task of these nodes is to obtain the data packet of the elevator operation command and its own position signal, as the absolute value position data and communicates with the upper computer to transmit the signal; certainly, the position and quantity of the fixed node 7 can be selected according to actual needs;

[0071] The electronic ruler is a linear positioning sensing device with a communication interface (selection rules: the positioning accuracy of mm level can meet the requirements of relevant techni...

Abstract

The invention discloses an added elevator settlement data acquisition system and method. The system comprises a position coding device fixed on an existing building, a linear displacement sensor and a data processing unit. The position coding device is matched with a reading head disposed at a set position of an elevator car so as to record absolute position data of operation and parking leveling of the elevator car in the vertical direction; the linear displacement sensor is arranged between an elevator steel structure main body and the existing building and is used for acquiring the relative position offset of an elevator steel structure and the existing building; and the data processing unit is configured to receive the absolute value position data and the relative position offset data, and the incidence relation between the absolute position data of an elevator at different operation positions, different operation conditions and / or different operation seasons and the settlement amount of the elevator steel structure main body is formed based on the deviation of the absolute value position data and the relative position offset data.

Description

technical field [0001] The invention relates to the technical field of elevator data monitoring, in particular to a system and method for collecting data on elevator subsidence. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The installation of elevators in existing buildings has received widespread attention from the society in recent years. It is a social and people's livelihood project supported by the market and the government; it will also be a future development trend to reduce the "demolition" of existing buildings and encourage "old renovation". Elevator products have great market demand and capacity space. [0004] Usually, steel structure wells are used to install elevators in existing buildings, and elevator equipment is placed in them. Since the main body of the elevator and the existing building belong to two completely dif...
