Description

Technical Field

[0001] This invention relates to a method and apparatus for monitoring elevator assembly. More specifically, this invention relates to a solution for ensuring that prefabricated shaft sections are processed according to an assembly plan. Background Technology

[0002] In recent years, the construction industry has adopted new building technologies with the aim of accelerating and improving the efficiency of the construction process. These changes have also impacted elevators, necessitating solutions adapted to modern building technologies.

[0003] One known solution is to construct the elevator in such a way that the elevator shaft comprises multiple interconnected shaft sections to provide a shaft space. The elevator car is arranged within the shaft space to move vertically between doors at building floors.

[0004] In practice, shaft sections may be prefabricated as modules at a location outside the building construction site. These shaft sections may be equipped with landing doors or other equipment, so that once the shaft sections are lifted and stacked on top of each other at the construction site, these prefabricated shaft sections can be assembled into a complete elevator shaft as easily as possible.

[0005] This method of constructing elevator shafts presents new challenges. It is necessary to ensure that shaft sections are transported and lifted at the right time, and to ensure that shaft sections damaged during handling do not end up in the building. Summary of the Invention

[0006] The objective of this invention is to address the aforementioned challenges. This objective is achieved by the method according to independent claim 1 and the apparatus according to independent claim 8.

[0007] When the prefabricated shaft section is equipped with sensors that generate sensor data during the prefabrication process, and the transmitter is activated to transmit the sensor data, monitoring of the shaft section becomes possible in a way that provides all parties involved in elevator assembly with the information necessary to ensure successful elevator assembly.

[0008] Preferred embodiments of the invention are disclosed in the dependent claims. Attached Figure Description

[0009] In the following description, the invention will be described in more detail by way of example and with reference to the accompanying drawings, wherein

[0010] Figure 1 and Figure 2 The illustration shows a device, and

[0011] Figure 3 The illustration shows a method for monitoring elevator assembly. Detailed Implementation

[0012] Figure 1 and Figure 2 The diagram illustrates a device. Figure 1 The diagram illustrates the prefabricated shaft section of the elevator shaft, and Figure 2 The illustration shows details of the shaft section and data storage device.

[0013] In practice, Figure 1 The shaft section 1 can be prefabricated as a module having a shaft space 9 for the elevator car 17. Manufacturing can be carried out at a location other than the building site. These shaft sections can be equipped with landing doors 2 and / or other equipment so that, once the shaft sections are lifted and stacked on top of each other at the building site, these prefabricated shaft sections can be assembled into a complete elevator shaft as easily as possible. Typically, for example, the shaft section 1 can be made of steel so that each shaft section 1 can bear the weight of the shaft sections arranged on top of it.

[0014] from Figure 1 It is clear that shaft sections 1 are not entirely identical. Typically, at least the uppermost shaft section 6 and the lowermost shaft section 3 differ in implementation from the middle shaft sections 4 and 5. For example... Figure 1 As shown, the elevator car 17 can be pre-assembled in the lowermost shaft section 3. Figure 1 The text also posits four different types of well sections 3 to 6 used in this embodiment, illustrated by example. Therefore, the order in which the well sections are lifted to their appropriate positions at the installation site is important.

[0015] To assemble the elevator shaft sections 3 to 6 shown in the diagram, an assembly plan is required. This assembly plan preferably defines the manufacturing sequence, transportation sequence, and hoisting sequence of shaft section 1. With such an assembly plan, it can be ensured that the elevator shaft is assembled in the correct sequence to obtain an operational elevator. The assembly plan may also include information regarding time. In particular, manufacturing time, transportation time, and hoisting time should be predefined to ensure that shaft section 1 is manufactured on time, minimizing unnecessary storage at the construction site or other locations. Furthermore, the assembly plan may include information on how the shaft sections should be handled. More specifically, permissible acceleration (impact during handling) and limits for humidity and temperature. Additionally, information about the parties involved can be defined in the assembly plan, allowing a message to be transmitted to the correct recipient when at least one criterion defined in the assembly plan is met. This makes it possible for the correct personnel to be informed of the elevator assembly progress.

[0016] Figure 2 The diagram shows Figure 1 Details of the shaft section 5 and data storage device 16 shown. Figure 1 Similar to all other shaft sections 1, shaft section 5 has been prefabricated to have a shaft space 9 for the elevator car and at least one of a lower connection interface 7 and an upper connection interface 8. Figure 2 The shaft section 5 shown has both a lower connecting interface 7 and an upper connecting interface 8. Since this shaft section 5 is intended to be positioned as an intermediate section between the uppermost elevator section 3 and the lowermost elevator section 6, it is connected to the shaft sections below and above it via the lower interface 7 and the upper interface 8 during assembly.

[0017] The hoistway section 5 is provided with a sensor device 10, which has a sensor and a transmitter to generate sensor data. During the prefabrication of the hoistway section, the sensor device 10 is activated to transmit sensor data. In the example shown, the sensor device 10 is connected to a top frame 11, such as a beam, which carries the landing door 2 of the hoistway section 5; however, in other embodiments, the sensor device 10 may be located in other parts of the hoistway section.

[0018] The transmitter implemented in sensor device 10 can be configured to wirelessly transmit sensor data via base station 11 of communication system 12, and forward the sensor data from the base station to data storage device 16. Data storage device 16 can be implemented as a server running software that controls the operation of data storage device 16, such that the received sensor data is stored in memory 13. For simplicity, in Figure 2 The memory 13 is illustrated by way of example as part of the data storage device 16, although in some embodiments it may be a separate device from the data storage device.

[0019] Data storage devices can also be implemented as cloud services provided by service providers. An alternative is to utilize sensor devices and data storage provided by Sensolus, such as the Rijsenbergstraat 148D, 9000 Gent, and Belgium.

[0020] exist Figure 2 In the example shown, access to sensor data stored in data storage device 16 is provided to terminal 14, which can be a wired or wireless terminal capable of communicating with data storage device 16 via a wired or wireless communication path. Thus, the parties involved in the assembly from hoistway section 1 to the elevator can receive messages from data storage device 16 via terminal 14 and monitor sensor data originating from sensor device 10 in hoistway section 5 and other sensor devices in the hoistway section. This makes it possible for the parties to ensure that the elevator assembly is completed on time and according to the assembly plan.

[0021] Sensor device 10 may include a positioning module, such as a module capable of determining the location of shaft section 5 based on GPS (Global Positioning System) signals. In this case, sensor device 10 includes the location of shaft section 5 in the generated sensor data. Therefore, after shaft section 5 is prefabricated and transported to the construction site, and when it is finally lifted to its final position in the shaft at the construction site, the participating parties can monitor the location of shaft section 5 via terminal 14.

[0022] Alternatively or additionally, sensor device 10 can generate sensor data indicating at least one of humidity, temperature, and acceleration. This allows participating parties to monitor how the prefabricated shaft section 5 is handled and stored during transportation and storage, before it is finally installed at the construction site.

[0023] In some embodiments, the data storage device 16, which receives and stores sensor data in memory 13, can also maintain an assembly plan for the elevator assembled using predefined hoistway sections 1. This makes it possible to configure the data storage device 16, for example by a computer program, to monitor the transmitted sensor data and the assembly plan, and to trigger the transmission of a message to a predetermined recipient when the sensor data meets at least one predefined criterion defined in the assembly plan. Such a message can be an alarm if the sensor data transmitted from one or more prefabricated hoistway sections 5 deviates from one or more limit values ​​set in the predefined assembly plan. An advantage of this solution is that, in such cases, when assembly is not proceeding according to the assembly plan, the parties involved in monitoring the elevator assembly can automatically send an alarm, such as an alarm message, to their terminals 14. Alternatively, the message can simply notify the recipient of the progress in the assembly, for example, informing a participating party that the hoistway section has reached a defined location, such as a construction site. In this way, the participating parties can continuously and automatically receive information about the progress in the assembly, making it easier for them to schedule their work tasks according to the actual progress.

[0024] In different implementations, the exact time at which the alarm is triggered may vary. One alternative is that the data storage device 16 triggers the alarm if sensor data indicates that the hoistway section has been moved to a location that does not correspond to the position indicated in the assembly plan. In this case, the party responsible for transporting the hoistway section 5 may initially become aware that the hoistway section has been prefabricated and is ready for transport to the construction site because the sensor device 10 is activated, and the data storage device initially receives and stores sensor data from that particular hoistway section 5. Subsequently, for example, if, based on the sensor data, the hoistway section 5 is transported to a position that does not correspond to the construction site location, the alarm can be triggered by the data storage device to the party responsible for transport. Another alternative is that the alarm can be triggered if sensor data indicates that the hoistway section 5 is transported to the construction site in the wrong order, or is raised to the wrong position in the elevator shaft at the construction site.

[0025] Similarly, the transport time of shaft section 5 is also important because the delivery of different shaft sections 1 at precisely planned times improves elevator assembly efficiency by avoiding unnecessary storage of shaft sections at intermediate locations within the elevator shaft from the manufacturing site to the construction site. Therefore, if a shaft section is not transported or lifted to the appropriate position during the time intervals defined in the assembly plan, an alarm can be triggered. Since the position of the shaft sections can be monitored in real time via data storage device 16, it is easier for all parties involved in elevator assembly to adjust their timings to achieve optimal delivery and assembly times for shaft sections in the correct sequence.

[0026] An alarm can also be triggered if the data storage device 16 detects that sensor data indicating at least one of humidity, temperature, or acceleration is outside the corresponding predetermined range defined in the assembly plan. In this case, one of the parties involved in the assembly can check the condition and quality of the well section 5 before installation.

[0027] As an alternative to triggering an alarm, the data storage device 16 can also be configured to trigger the transmission of a message to a predetermined receiver when the position of the hoistway section 5 corresponds to a predetermined position defined in the assembly plan. These messages can be transmitted when the prefabrication of the hoistway section 5 is completed (when the data storage device 16 receives data from the first sensor), when the hoistway section begins to move from the pre-assembly stage, when the hoistway section has reached its location at the construction site, when the hoistway section is lifted at the construction site, and when the hoistway section 5 reaches its final position in the elevator shaft. Because of these messages, one or more parties involved in the elevator assembly can obtain continuous updates on the status of the elevator section 5 from their available terminal 14.

[0028] Once all elevator shaft sections 1 have been installed in the elevator shaft, and the elevator car 17 and elevator control unit 18 have been powered on, the elevator control unit 18 can begin receiving sensor data transmitted by the transmitter in the sensor device 10. The elevator control unit 18 can receive sensor data directly from the sensor devices 10 in each shaft section 3 to 6, or alternatively, for example, via the data storage device 16.

[0029] The elevator control unit 18 does not require all sensor data generated during elevator assembly, making it possible to separate some sensors from the sensor equipment. However, sensor data indicating, for example, acceleration is useful because it indicates vibration in different parts of the hoistway during elevator operation. This sensor data, along with sensor data generated by sensors in the elevator car, can be used by the elevator control unit 18 to determine if the vibration exceeds a limit, thus triggering an alarm. In this case, adjusting the rails or other equipment may be beneficial for achieving smooth operation of the elevator car.

[0030] Figure 3 The illustration shows a method for monitoring elevator assembly. Figure 3 The method can be with Figure 1 and Figure 2 The devices were used together.

[0031] In step A, multiple shaft sections 1 can be prefabricated, each shaft section having a shaft space 9.

[0032] During the prefabrication process in step B, sensor device 10 is provided to hoistway section 5, and this sensor device is also activated during prefabrication to transmit sensor data to data storage device 16 via a communication system. This makes it possible to monitor the sensor data stored in the memory of the data storage device in step C. Therefore, after the manufacture of hoistway section 5, the parties involved in the elevator assembly can detect via data storage device 16 that the prefabrication of hoistway section 5 has been completed.

[0033] In step D, shaft section 5 is transported to the construction site, where elevator shaft assembly takes place. Using sensor data, including the location of shaft section 5, the participating parties can determine that the different shaft sections 3 to 6 are transported to the construction site in the correct order and on time. Furthermore, sensor data, including humidity, temperature, and acceleration, enables the parties involved in elevator shaft assembly to ensure that the shaft sections are handled correctly during storage and transportation.

[0034] In step E, the hoistway sections 1 are lifted and stacked on top of each other, and the hoistway spaces 9 are aligned to form a hoistway for the elevator car 17. Using sensor data including the positions of the hoistway sections 1, the participating parties can determine that the different hoistway sections are lifted to their appropriate positions in the correct order and on time according to the assembly plan. If a particular hoistway section 5 is lifted too early or too late compared to the other hoistway sections 3 and 4, it means that the hoistway section has been lifted to a position in the hoistway that does not correspond to its position according to the assembly plan.

[0035] In step F, if the sensor data meets at least one predetermined criterion defined in the assembly plan, the transmission of a message to a predetermined recipient is triggered. The transmitted message could be an alarm message triggered when sensor data indicates that the elevator assembly has not been carried out according to the assembly plan. The triggering of this alarm and the monitoring in step C can be automated, for example, by storing the assembly plan in memory in addition to the sensor data. In that case, the data storage device can be configured to automatically monitor the sensor data, compare it with the assembly plan, and trigger the transmission of an alarm to the predetermined participating parties if the sensor data indicates that the assembly has not been completed according to the assembly plan. Alternatively, the transmission of a message can be triggered when the location of a section of the hoistway corresponds to a predefined location defined in the assembly plan. In that case, a party involved in the elevator assembly can obtain information that the prefabricated hoistway has reached a specific location, such as the construction site or its final location within the hoistway.

[0036] It should be understood that the above description and accompanying drawings are intended to illustrate the invention only. It will be apparent to those skilled in the art that variations and modifications can be made to the invention without departing from its scope.
