Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a hoisting device, a system and a construction method for a shaft pipeline. Background Art

[0002] In the traditional construction process, the hoisting of the shaft pipe is a complex and challenging task. Usually, the installation of the shaft pipe relies on the construction personnel's experience and judgment and the use of simple measuring tools such as level and tape measure. This method is not only time-consuming and labor-intensive, but also prone to large installation errors, which affects the sealing and stability of the entire pipe system and the accuracy of subsequent pipe docking.

[0003] At present, the widely used pipeline hoisting methods mainly include the inverted installation method and the straight installation method. The inverted installation method requires construction workers to install pipelines from the top floor of the building layer by layer. Although this method is more convenient to operate at high altitudes, its main disadvantage is that the installation errors of the high-rise floors may accumulate layer by layer to the lower floors, resulting in serious deviations in the position of the bottom-level pipelines. The straight installation method is to install pipelines layer by layer from bottom to top. Although it reduces the problem of error accumulation to a certain extent, its frequent vertical transportation and operation in a small space greatly reduce the construction efficiency and have a high construction safety risk.

[0004] In addition, in the prior art, the monitoring of the posture and position of pipeline hoisting mainly relies on manual visual inspection, lacking accurate real-time monitoring means. This situation easily leads to problems such as tilting and deviation from the path during pipeline hoisting, thereby increasing the difficulty of pipeline installation and the cost of subsequent adjustments.

[0005] In order to solve the above problems, the existing technology has gradually introduced advanced equipment such as sensors and laser ranging to assist pipeline hoisting, but the integration of these devices is not high, the real-time transmission and feedback capabilities of data between systems are weak, and they cannot effectively support the precise hoisting requirements in complex environments. Especially in narrow and poorly lit well environments, traditional installation methods and equipment are difficult to meet the requirements of high-precision and high-efficiency construction. Summary of the invention

[0006] In order to solve the shortcomings existing in the above-mentioned prior art, the present invention aims to provide a shaft pipe hoisting device, system and construction method that integrates multiple advanced sensor technologies and utilizes a digital twin system to perform real-time monitoring and dynamic adjustment of the shaft pipe, so as to improve the accuracy and construction efficiency of the hoisting process and significantly reduce construction safety risks.

If not, a pause command is sent to the industrial computer; the digital twin shaft pipeline hoisting model is a BIM model established based on the on-site environmental parameters of the pre-hoisting point and the parameters of the shaft pipeline to be hoisted, and is updated according to the real-time hoisting parameters transmitted by the industrial computer.

[0024] The present invention also provides a shaft pipe hoisting construction method based on the shaft pipe hoisting system, comprising the steps of:

[0025] S1. A basic sensor device is arranged at the bottom of the pre-lifting point, and a plurality of laser emitters emit visible lasers vertically upward to form a laser channel that defines the hoisting path and hoisting position of the hoisting pipe in the well;

[0050] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0051] Example 1

[0052] like Figure 1 As shown, this embodiment provides a hoisting device for a well pipe, comprising:

[0053] The basic sensor device 1 arranged at the bottom of the pre-hanging point is used to limit the hoisting position and hoisting path of the shaft pipe. It should be understood that the bottom of the pre-hanging point may be a floor 6 or a floor, or a section of shaft pipe that has been installed and fixed in advance, depending on the actual situation on site. The limitation described in the present invention is not a physical level limitation in the traditional sense, but is achieved by setting a virtual limited area and limited parameters. During the hoisting process, when the hoisting behavior of the pipeline exceeds the preset limited area or exceeds the limited parameters, the reporting or alarm mechanism is immediately triggered. On the one hand, the current hoisting action is automatically suspended to avoid further misoperation or safety hazards; on the other hand, an alarm signal will be sent to the construction personnel, and they will be reminded to confirm the current construction status through a visual interface, sound or vibration, and make corresponding decision adjustments. This intelligent monitoring and feedback mechanism based on virtual limitation significantly improves the safety and accuracy of the hoisting process, and effectively prevents construction accidents or engineering quality problems caused by operational deviations.

[0054] Specifically, the basic sensing device 1 includes:

[0055] Several laser emitters 11 are arranged along a circumference not less than the outer contour of the cross section of the pre-lifted shaft pipe 4, and the visible laser 7 of the laser emitter 11 is emitted vertically upward. The visible lasers emitted by the laser emitters 11 together constitute a laser channel for defining the lifting position and lifting path of the shaft pipe. Preferably, it can be achieved by evenly distributing four laser emitters 11 on a circumference not less than the outer contour of the cross section of the pre-lifted shaft pipe 4. It should be understood that the specific size of the circumference can be set by those skilled in the art according to the actual situation and needs on site, and the present invention does not make further limitations. According to different construction environments and the size of the shaft pipe, the number and arrangement of the laser emitters 11 can be flexibly adjusted to ensure that the optical channel can accurately define the lifting path of the shaft pipe, thereby improving the accuracy and safety of the construction.

[0056] A displacement sensor 12 is arranged at the center of the circle where the laser emitter 11 is arranged, and the detection direction of the displacement sensor 12 is vertically upward. The displacement sensor 12 in this embodiment mainly plays two roles: one is to determine the installation position of the sling 3 through the irradiation point of the displacement sensor 12; the other is to measure the actual hoisting height of the shaft pipe during the current hoisting process. Specifically, since the sling 3 in this embodiment lifts the shaft pipe from the bottom, and the displacement sensor 12 is located at the center of the shaft pipe, the vertically upward detection light of the displacement sensor 12 will be reflected when it encounters the sling 3, instead of directly passing through the shaft pipe. By detecting the reflected light, the displacement sensor 12 can accurately measure the distance between the sling 3 and the sensor, thereby calculating the hoisting height of the shaft pipe in real time.

[0057] The first attitude sensor 2 arranged on the outer surface of the hoisting shaft pipe 4 is used to obtain the attitude information of the hoisting shaft pipe 4 during the hoisting process. The attitude sensor is a device for detecting and measuring the attitude or position of an object, and generally uses various sensor technologies, such as accelerometers, gyroscopes and magnetometers, to obtain attitude information such as the direction, rotation angle and position of the object in space. The function of the first attitude sensor 2 in this embodiment is to obtain the attitude information of the hoisting shaft pipe 4 during the hoisting process. Specifically, the first attitude sensor 2 can monitor the inclination angle, rotation angle and other related attitude parameters of the pipeline in real time during the hoisting process, and transmit these data to the control system. By obtaining these attitude information, the system can accurately and dynamically monitor the actual state of the pipeline, ensure that the pipeline remains within the predetermined path and attitude range during the hoisting process, and avoid deviation or tilt.

[0058] The hoist 3 is used to lift the shaft pipe from the bottom to achieve the hoisting of the shaft pipe. It should be understood that the present invention does not intend to make a detailed limitation on the specific structure and actual model of the hoist 3, and those skilled in the art can make a reasonable choice based on the purpose to be achieved by the present invention and the conventional technology in the field.

[0059] In some preferred embodiments, Figure 2 As shown, a specific structural example of a basic sensor device 1 designed in combination with the characteristics of the well pipe is given, including:

[0060] The inner diameter of the mounting ring 13 is larger than the outer diameter of the shaft pipe, and the laser emitter 11 is arranged outside the mounting ring 13 .

[0061] The outer diameter of the mounting plate 14 is larger than the outer diameter of the shaft pipe and is concentrically arranged with the mounting ring 13; the displacement sensor 12 is arranged at the center of the upper surface of the mounting plate 14. Preferably, the mounting plate 14 is in front of the mounting ring 13 along the lifting direction. When the bottom of the pre-hanging point is a floor 6 or a floor, the mounting ring 13 is directly fixed on the surface of the floor 6 or the floor; when the bottom of the pre-hanging point is a shaft pipe that has been installed and fixed in advance, the mounting ring 13 is sleeved on the outer surface of the fixed shaft pipe, and the mounting plate 14 is in contact with the end plane of the fixed shaft pipe.

[0062] The connecting rod 15 is connected to the mounting ring 13 and the mounting plate 14 at both ends and is rotatably connected to at least one of the mounting ring 13 and the mounting plate 14. The purpose of setting the connecting rod 15 in this way is to take into account that when the bottom of the pre-hanging point is a section of the well pipe that has been installed and fixed in advance, especially when the last section of the hoisting well pipe 4 is hoisted in place, the gap between the well pipes is small, and the space for the basic sensor device 1 to move up and down in this case is limited, resulting in the traditional design of the basic sensor device 1 may not be smoothly disassembled. Through the design of this embodiment, during the disassembly process, the mounting plate 14 can first be adjusted to an appropriate position by a rotational connection, so as to make room for the necessary space for moving the mounting ring 13 up and down. Then, the operator can move the mounting ring 13 up and down to successfully complete the disassembly of the basic sensor device 1. This design effectively solves the problem of disassembling equipment in a small space, ensures that the basic sensor device 1 can be easily installed and disassembled under different construction conditions, and improves the flexibility and efficiency of construction.

[0063] In other preferred embodiments, considering that the installation posture of the basic sensor device 1 has an important influence on the subsequent limit realization and data collection, a second posture sensor on the upper surface of the mounting plate 14 is considered, and the second posture sensor is used to obtain the posture information of the basic sensor device 1 during use. By setting the second posture sensor, the system can accurately monitor the tilt angle and direction of the basic sensor device 1, thereby ensuring that the basic sensor device 1 always maintains an ideal working state in a complex construction environment.

[0064] Example 2

[0065] like Figure 3 As shown, this embodiment is developed on the basis of the above-mentioned embodiment 1. This embodiment provides a hoisting system for a well pipe, including:

[0066] A hoisting device for the shaft pipe as described in Example 1.

[0067] The industrial computer, which is respectively connected to the laser transmitter 11, displacement sensor 12, attitude sensor and hoist 3 of the hoisting device of the shaft pipe, is used to collect the signals of the laser transmitter 11, displacement sensor 12 and attitude sensor, and control the start and stop of the hoist 3. Among them, the attitude sensor includes a first attitude sensor 2 and a second attitude sensor according to the actual setting conditions on site. It should be understood that the industrial computer is not only a signal receiver and processor in this embodiment, but also the control center of the entire hoisting operation. It ensures that the hoisting operation is carried out under precise and safe conditions through real-time data processing, transmission and feedback control.

[0068] The server connected to the industrial computer signal and having a built-in digital twin shaft pipeline hoisting model and monitoring indicators is used to display the digital twin shaft pipeline hoisting model in real time, and judge whether the current hoisting state meets the requirements according to the uploaded signal and the monitoring indicators. If not, a pause command is sent to the industrial computer; the digital twin shaft pipeline hoisting model is a BIM model established according to the pre-hoisting point site environmental parameters and the parameters of the shaft pipeline to be hoisted 4, and is updated according to the real-time hoisting parameters transmitted by the industrial computer. Among them, the monitoring indicators are some key control parameters of the shaft pipeline hoisting operation formulated by technical personnel in this field according to the actual situation of the construction site and relevant construction design and construction specifications. These monitoring indicators include but are not limited to: whether the shaft pipeline exceeds the limit, hoisting height, hoisting angle, hoisting rotation angle and hoisting speed. If the uploaded signal during the hoisting process exceeds any of the above monitoring indicators, it means that there is a problem in the hoisting process, and it is necessary to stop the machine immediately to avoid further development of the danger, and the technical personnel need to be notified in time. The specific implementation method of the digital twin shaft pipe hoisting model can be selected and set by technical personnel in this field according to existing conventional technologies, and the present invention does not make further limitations. However, no matter what technical means are selected, they should not deviate from the purpose of the present invention for its application, that is, the present invention requires that the model can accurately reflect the actual status of the shaft pipe during the on-site hoisting process, and provide timely feedback and decision-making support to construction personnel to ensure the accuracy and safety of the hoisting operation.

[0069] Example 3

[0070] like Figure 1 and Figure 4 As shown, this embodiment is developed on the basis of the above-mentioned embodiment 2. This embodiment provides a shaft pipeline hoisting construction method based on the shaft pipeline hoisting system, comprising the steps of:

[0071] The foundation layout stage focuses on setting up the basic sensor device 1 and other monitoring signal acquisition sensors to ensure accurate control and real-time monitoring during the hoisting process of the well pipe:

[0072] S1. A basic sensing device 1 is set at the bottom of the pre-lifting point. The visual lasers 7 emitted vertically upward by the plurality of laser emitters 11 form a laser channel for defining the lifting path and lifting position of the hoisting pipe of the hoisting shaft, which is used to accurately define the lifting path and lifting position of the hoisting pipe of the hoisting shaft, ensuring that the pipe always remains within the predetermined trajectory and position during the lifting process.

[0073] S2. The displacement sensor 12 measures the distance from the bottom of the pre-hanging point to the top of the pre-hanging point, and a sling 3 is arranged at the irradiation point of the displacement sensor 12 at the top of the pre-hanging point.

[0074] S3. A first attitude sensor 2 is arranged on the outer surface of the hoisting shaft pipe 4 to obtain the attitude information of the hoisting shaft pipe 4 in real time during the hoisting process. Through the attitude sensor, the system can monitor and feedback the inclination angle and rotation state of the pipe, so as to make necessary adjustments during the hoisting process to ensure that the pipe always remains within a safe and predetermined attitude range.

[0075] The lifting phase focuses on executing and monitoring the hoisting operation of the shaft pipes by relying on the digital twin model and sensor feedback to ensure that each step is completed under precise control:

[0076] S4. Use the hoist 3 to lift the hoisting shaft pipe 4 from the bottom, and under the guidance of the digital twin hoisting shaft pipe model, perform the pipe lifting operation according to the predetermined lifting path and steps, while monitoring the posture and position of the hoisting shaft pipe 4 in real time. By monitoring the posture and position of the hoisting shaft pipe 4 in real time, ensure that the pipe rises smoothly along the set path to avoid deviation or abnormal posture.

[0077] It should be noted that the realization of posture and position monitoring of the hoisting shaft pipe 4 depends on the comparison and judgment of the data collection of several sensors set in the basic layout stage and the preset monitoring indicators. In some preferred embodiments, some examples of judgment based on the signals transmitted by each sensor are given, including:

[0078] The displacement sensor 12 continuously transmits the distance signal from the bottom of the hoist 3 to the industrial computer. The distance signal represents the lifting height of the hoisting shaft pipe 4. The industrial computer monitors the hoisting progress of the shaft pipe in real time by analyzing the signal. When the lifting height reaches the preset lifting height, the industrial computer will determine that the shaft pipe has been hoisted in place. After this judgment is triggered, the system will instruct to stop the hoisting operation and enter the next step of the fixing installation procedure to ensure the accurate positioning and safe fixing of the pipe.

[0079] The laser transmitter 11 continuously transmits a limit signal to the industrial computer, which is used to monitor the operating status of the hoisting shaft pipe 4 within the predetermined path. When the shaft pipe rises along the hoisting path, the visual laser 7 emitted by the laser transmitter 11 should always remain continuous and stable. If the limit signal is interrupted, the industrial computer will recognize this interruption as a sign that the hoisting shaft pipe 4 deviates from the predetermined hoisting path. At this time, the industrial computer will immediately trigger an alarm and instruct to stop the hoisting operation to avoid further deviations or possible safety risks, and require the operator to check and adjust.

[0080] The first attitude sensor 2 continuously transmits attitude signals to the industrial computer, and the attitude signals include key parameters such as the tilt angle, vertical movement speed, and rotation speed and angle of the hoisting shaft pipe 4. The industrial computer monitors the state of the shaft pipe during the hoisting process in real time by analyzing these attitude signals. If the system detects that the tilt angle exceeds the predetermined range, the vertical movement speed is abnormal, or the rotation speed is too fast, the industrial computer will make adjustments in time, or suspend the hoisting operation when necessary, to avoid potential risks caused by abnormal pipeline attitude and ensure the safety and accuracy of the entire hoisting process.

[0081] S5. The server updates the digital twin shaft pipe hoisting model according to the posture and position parameters of the hoisting shaft pipe 4 to display the real-time progress of the hoisting construction; the server determines whether the posture and position parameters of the hoisting shaft pipe 4 meet the requirements of the monitoring indicators. If not, a pause command is sent to the industrial computer to wait for further instructions from the operator; if all parameters meet the requirements, the hoisting operation will continue.

[0082] S6. After the hoisting shaft pipe 4 is hoisted to the predetermined position, the hoisting shaft pipe 4 is fixedly installed to become a fixed shaft pipe 5. Specifically, the shaft pipe is fixed by welding, riveting or other fixed connection methods according to the requirements of the on-site construction, so that it is firmly connected with other installed pipes or floor slabs 6.

[0083] S7, repeat the above steps S4-S6 to complete the hoisting of all hoisting shaft pipes 4. The hoisting operation of all shaft pipes is completed section by section until the entire pipe system is fully installed.

[0084] Example 4

[0085] like Figure 5 As shown, the present invention also provides a comprehensive monitoring and decision-making support system for the hoisting process of the shaft pipeline, which aims to achieve real-time monitoring, virtual modeling and safety alarm of the status during the hoisting process through various means such as sensors, lasers and audio and video monitoring, so as to improve construction efficiency and ensure hoisting safety.

[0086] The system of this embodiment is composed of the following parts:

[0087] Condition monitoring system: Hoisting pipeline status: Use a variety of sensors (such as displacement sensors and attitude sensors) to obtain the posture, position and motion parameters of the well pipe in real time, including inclination angle, vertical height and rotation speed.

[0088] Hoisting environment status: Monitor the environmental conditions in the shaft through environmental sensors (such as temperature, humidity, and air pressure sensors) arranged at the construction site to ensure that the construction conditions meet the hoisting requirements.

[0089] Auxiliary sensor system: Auxiliary sensors are used for supplementary monitoring in special environments, such as light intensity and noise level in the well, to ensure that construction personnel can operate in a safe and comfortable environment.

[0090] Laser monitoring system: Several laser transmitters are arranged at key positions on the lifting path. The laser beams are directed vertically upward to form a visual lifting channel to ensure that the pipeline always moves along the set path during the lifting process. Once the lifting pipeline deviates from the path, the laser signal interruption will trigger a system alarm.

[0091] Audio and video monitoring system: During the hoisting process, cameras and microphones are deployed to realize real-time audio and video monitoring of the construction site, helping construction personnel to intuitively judge the progress of the hoisting operation and promptly discover and handle abnormal situations.

[0092] Through high-definition video and audio capture, combined with laser and sensor data, a comprehensive record and backtracking of the lifting process is formed to facilitate subsequent construction optimization and quality traceability.

[0093] Virtual pipeline modeling and decision support: The system uses digital twin technology to build a virtual pipeline model and updates it in real time based on data from sensors and laser equipment. This virtual model is used to assist decision making and displays the hoisting status of the pipeline in the well in real time, allowing construction personnel to grasp the precise position and posture of the pipeline at any time.

[0094] Safety status alarm system: Based on virtual models and sensor data, it analyzes and predicts potential safety hazards that may occur during the lifting process. Once an over-limit situation is detected, the system immediately issues an alarm and terminates the lifting operation, prompting construction personnel to make adjustments.

[0095] Decision support module: This module integrates status monitoring, laser detection and audio and video data to make optimization suggestions for lifting operations, helping construction personnel make reasonable decisions to improve construction efficiency and lifting accuracy.

[0096] Through the comprehensive application of the above-mentioned monitoring, modeling and alarm systems, the lifting system of this embodiment can effectively improve the accuracy, safety and construction efficiency of pipeline lifting, and is particularly suitable for well scenarios with complex environments and narrow spaces.

[0097] Example 5

[0098] like Figure 6 As shown, the present invention further provides a system solution for state optimization and intelligent assistance during the hoisting process to improve the predictability, safety and decision-making effectiveness of the hoisting operation. This embodiment includes the following functional modules:

[0099] Predictability module:

[0100] 1. Data prediction: Based on the data collected by multiple sensors, the key parameters of the lifting process are predicted through historical data analysis and modeling.

[0101] 2. Decision support: Combine the digital twin model and real-time monitoring data to form a prediction of abnormal situations that may occur during the pipeline lifting process and provide optimization solutions in advance.

[0102] 3. AI monitoring of external interference: Use artificial intelligence to monitor and analyze external interference in the construction environment (such as weather changes, external force influences, etc.) to ensure the stability and safety of the construction process.

[0103] Lifting task detailed management module:

[0104] 1. Task division: According to the actual needs of the pipeline lifting process, the construction tasks are broken down into small executable steps, including preparation, installation, commissioning and other different stages.

[0105] 2. On-site monitoring: Various sensors are deployed at different construction stages for real-time monitoring to ensure that each step is executed according to the predetermined plan.

[0106] AI intelligent optimization module:

[0107] 1. Geometry detection and environmental perception:

[0108] 1.1. Geometric detection: During the lifting process, the AI ​​system analyzes the relative position and geometric relationship between the pipeline and the well in real time to ensure accurate alignment.

[0109] 1.2 Environmental perception: Use a variety of sensors and laser equipment to perceive the environmental conditions (such as lighting, space conditions, etc.) at the lifting site to provide a reference for construction operations.

[0110] 2. Information feedback and intelligent control: The results of geometric detection and environmental perception are fed back to the lifting system, and the lifting path and posture are adjusted through AI decision-making to achieve higher precision and safer lifting operations.

[0111] Security module:

[0112] 1. Multi-level security strategy: Based on AI prediction results, different security measures are dynamically generated, the security of each step is evaluated, and emergency plans are formulated.
