Description

Technical Field

[0001] The invention belongs to the technical field of a trolley for safely transporting earthwork in a pipeline for pipe jacking construction, and relates to a trolley for safely transporting earthwork in a pipeline for pipe jacking construction based on sensor technology. Background Art

[0002] Pipe jacking construction is an important underground pipeline construction method, during which earth needs to be transported out of the pipeline safely and efficiently. Earth transport vehicles usually refer to small vehicles used for short-distance handling and transportation of earth and stone and other materials. Earth transport vehicles can realize automated and intelligent material transportation without manual follow-up. During the pipe jacking construction process, the environment inside the pipeline is complex and changeable, such as insufficient light, narrow space, possible presence of toxic and harmful gases, high soil humidity, etc., which pose severe challenges to earth transportation. Traditional earth transportation methods often rely on manual operation, which is not only inefficient, but also poses great safety risks. Therefore, a sensor-based earth transportation vehicle for pipe jacking construction is of great significance and role.

[0003] In the prior art, there are also some related solutions involving transport carts. For example, the invention patent application for a walking state monitoring device and method of an aerial transport cart with a Chinese patent publication number of CN114890075B, the walking state monitoring device of the aerial transport cart includes: a sensor module is installed above the walking substrate, which is used to obtain the motion information of the aerial transport cart in real time during the operation of the aerial transport cart, and obtain the walking state information of the aerial transport cart based on the motion information. The judgment module is used to judge the abnormality of the running track according to the walking state information and the preset strategy, wherein the preset strategy includes the corresponding relationship between the walking state information and the abnormality of the running track. The reminder module is used to issue corresponding reminder information according to the abnormality of the running track. By acquiring the motion information of the aerial transport cart through the newly added sensor module, the running state of the aerial transport cart can be automatically monitored, avoiding the problem of affecting the safety of wafer box transportation due to abnormal running track.

[0004] Although the above scheme proposes some solutions for the transport cart, it still has certain limitations: on the one hand, the existing scheme mainly judges the abnormal situation of the running track based on the movement information of the transport cart and issues reminders. However, the existing scheme ignores the real-time detection and analysis of the loading, transportation and unloading processes of the transport cart in the whole transportation process, thereby being unable to avoid unnecessary waiting and delays in the loading, transportation and unloading processes, thereby being unable to improve the overall transportation efficiency and reduce transportation costs, and is not conducive to timely discovery and correction of potential safety hazards and reducing safety accidents caused by improper operation.

[0005] On the other hand, the existing scheme also lacks evaluation and feedback on the work status of the transport vehicle after the work is completed, which is not conducive to understanding the waste and irrationality in the transportation process, nor is it conducive to a comprehensive understanding of the performance and usage status of the transport vehicle, and thus it is impossible to carry out targeted vehicle management and maintenance and extend the service life of the vehicle. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 As shown, the present invention provides a sensor-based in-pipe earthwork safety transport vehicle for pipe jacking construction, comprising a vehicle body and a control system. The control system is mounted on the vehicle body, and the control system comprises specific modules distributed as follows: a data parameter analysis module, a control terminal, a transportation evaluation analysis module and a cloud database.

[0025] Among them, the connection method between the modules is: the data parameter analysis module is connected to the control terminal, the control terminal is connected to the transportation evaluation analysis module, and the cloud database is connected to the data parameter analysis module and the transportation evaluation analysis module respectively.

[0026] The data parameter analysis module is used to record each earthwork transport vehicle in the target pipe jacking construction pipeline as a designated earthwork transport vehicle, perform real-time detection on the entire transportation process of each designated earthwork transport vehicle, obtain data parameters of the entire transportation process of each designated earthwork transport vehicle, and analyze the evaluation of the entire transportation process of each designated earthwork transport vehicle, wherein the entire transportation process includes loading process, transportation process and unloading process.

[0027] It should be noted that the system process implementation diagram is as follows Figure 2 shown.

[0028] As a preferred feasibility example, the loading process data parameters of each designated earth transport vehicle include stop positioning deviation distance, earth loading volume and top earth protruding height.

[0029] It is necessary to further explain that the reason for using the stop positioning deviation distance, earthwork load and top earthwork protrusion height as the loading process data parameters of each designated earthwork transport vehicle is as follows: (1) The stop positioning deviation distance refers to the deviation distance between the actual parking position and the target position when the vehicle reaches the designated loading position. It reflects the degree of deviation of the earthwork transport vehicle relative to the predetermined position during the loading process. By monitoring this parameter, it can be ensured that the vehicle can accurately align with the loading point during loading, avoiding earthwork scattering or insufficient loading caused by loading deviation.

[0030] (2) Earthwork loading capacity refers to the weight of earthwork loaded on the trolley each time. By properly controlling the loading capacity, we can ensure that each transportation can achieve the best economic benefits and avoid transportation difficulties caused by overloading and waste of resources caused by underloading.

[0031] (3) The top earthwork protrusion height reflects the overall height of the earthwork after loading. By monitoring this parameter, it can be ensured that the earthwork after loading does not exceed the allowable height range of the transport vehicle, avoiding traffic safety hazards caused by over-high loading.

[0032] It needs to be further explained that the specific method of obtaining the stopping positioning deviation distance of the loading process of each designated earth-moving transport vehicle is: setting a reference mark at the target position, and then when each designated earth-moving transport vehicle approaches the target position, directly detecting the distance between each designated earth-moving transport vehicle and the target position through an ultrasonic sensor, and recording it as the stopping positioning deviation distance of the loading process of each designated earth-moving transport vehicle.

[0033] The specific method for obtaining the earthwork loading amount of each designated earthwork transport vehicle during the loading process is: using a weighing sensor arranged at the junction of the vehicle body and the truck bed to directly detect and obtain the earthwork loading amount of each designated earthwork transport vehicle during the loading process.

[0034] The specific method for obtaining the top earthwork protrusion height of each designated earthwork transport trolley during the loading process is: measuring the distance between the highest point of the earthwork surface and the top reference plane of the trolley through the deployed ultrasonic sensor, and recording it as the top earthwork protrusion height of each designated earthwork transport trolley during the loading process.

[0035] The transport process data parameters of each designated earth transport vehicle include driving stability, tilt angle and pitch angle, as well as earth scattering area and earth scattering length.

[0036] It is necessary to further explain that the reasons for using driving smoothness, tilt angle, pitch angle, earthwork scattering area and earthwork scattering length as the transportation process data parameters of each designated earthwork transport vehicle are as follows: (1) Driving smoothness refers to the degree of vibration and bumping of the vehicle during transportation. Smooth driving can reduce vehicle bumps and reduce the risk of earthwork scattering due to vibration, thereby ensuring the safety of the transportation process.

[0037] (2) The tilt angle refers to the degree of tilt of the vehicle in the horizontal direction. The tilt angle reflects the degree of tilt of the earth-moving vehicle during driving. Too large a tilt angle may cause the vehicle to roll over, resulting in serious safety accidents.

[0038] (3) The pitch angle refers to the relative height difference between the front and rear ends of the earth-moving transport vehicle during driving. By monitoring the pitch angle, the vehicle posture can be adjusted in time to avoid safety hazards caused by excessive tilt of the vehicle body.

[0039] (4) The earth scattering area refers to the ground area occupied by the earth that falls from the trolley during transportation, and the earth scattering length refers to the longest distance along the driving direction of the earth that falls from the trolley during transportation. By monitoring the earth scattering area and scattering length, earth scattering problems can be discovered and handled in a timely manner, reducing earth losses and improving transportation efficiency.

[0040] It should be further explained that the specific method for obtaining the driving smoothness of the transportation process of each designated earth-moving transport vehicle is: using the acceleration sensor arranged at the bottom of the vehicle to directly measure the acceleration of each designated earth-moving transport vehicle during the set monitoring time period. ,in , The numbers of the designated earth-moving transport vehicles. is the number of earthwork transport vehicles specified. , is the number of each monitoring. is the number of monitoring times, according to the calculation formula Get the driving stability of each designated earthwork transport vehicle during the transportation process ,in Set the permissible fluctuation value of acceleration monitored within the monitoring time period for the set transportation process.

[0041] The specific method for obtaining the tilt angle and pitch angle of each designated earth-moving transport vehicle during the transportation process is: using the deployed inclination sensors to measure and obtain the tilt angle and pitch angle of each designated earth-moving transport vehicle during the transportation process.

[0042] The specific method for obtaining the earth-scattering area and earth-scattering length of each designated earth-moving transport vehicle during the transportation process is as follows: cameras are placed at key positions on the transportation path to shoot the transportation process of each designated earth-moving transport vehicle to obtain images of the transportation process of each designated earth-moving transport vehicle, and then the images are processed through image processing technology to obtain the earth-scattering area and earth-scattering length of each designated earth-moving transport vehicle during the transportation process.

[0043] The unloading process data parameters of each designated earth transport vehicle include unloading area compliance and unloading completeness.

[0044] It is necessary to further explain that the reasons for using the unloading area conformity and unloading completeness as the unloading process data parameters of each designated earthwork transport vehicle are as follows: (1) The unloading area conformity refers to the degree of match between the actual unloading position of the earthwork and the preset unloading area during the unloading process of the vehicle. By monitoring the unloading area conformity, it can be ensured that the vehicle will not deviate from the preset position during the unloading process, thereby avoiding unloading the earthwork into the wrong area, causing unnecessary trouble and losses.

[0045] (2) Unloading completeness refers to whether the earthwork is completely unloaded by the trolley during the unloading process. By monitoring the unloading completeness, it can be ensured that the trolley does not leave too much earthwork residue during the unloading process, thereby avoiding adverse effects on the unloading area and subsequent operations.

[0046] It needs to be further explained that the specific method of obtaining the unloading area compliance of the unloading process of each designated earth-moving transport vehicle is: positioning sensors are arranged on the vehicle and the unloading area, and the position coordinates of each designated earth-moving transport vehicle and the position coordinate range of the target unloading area are obtained through the sensors, and the position coordinates of each designated earth-moving transport vehicle are compared with the position coordinate range of the target unloading area. If the position coordinates of a designated earth-moving transport vehicle are within the position coordinate range of the target unloading area, the unloading area compliance of the unloading process of the designated earth-moving transport vehicle is recorded as 1, otherwise, the unloading area compliance of the unloading process of the designated earth-moving transport vehicle is recorded as 0, thereby obtaining the unloading area compliance of the unloading process of each designated earth-moving transport vehicle.

[0047] It should be further explained that the specific method for obtaining the position coordinates of each designated earthwork transport vehicle and the position coordinate range of the target unloading area is: taking the position center point of the target pipe jacking construction pipeline outlet as the coordinate origin, taking the bottom horizontal line of the cross section of the target pipe jacking construction pipeline outlet as the horizontal axis, and making a straight line passing through the origin and perpendicular to the horizontal axis as the vertical axis to establish a two-dimensional coordinate system, such as Figure 3 As shown, the position coordinates of each designated earth-moving transport vehicle and the position coordinate range of the target unloading area are obtained.

[0048] The specific method for obtaining the unloading completeness of each designated earthwork transport vehicle during the unloading process is: using a weighing sensor arranged at the junction of the vehicle body and the vehicle bucket to directly detect the remaining earthwork load of each designated earthwork transport vehicle after unloading is completed. , analyze the unloading completeness of each designated earth transport vehicle during the unloading process ,in The preset allowable earthwork load remaining quantity, It is a preset minimum value that ensures that the denominator is not 0, and its unit is kilogram.

[0049] The data parameter analysis module includes an earthwork loading analysis unit, a transportation process analysis unit and an earthwork unloading analysis unit.

[0050] The connection between the units is as follows: the earthwork loading analysis unit is connected to the transportation process analysis unit, and the transportation process analysis unit is connected to the earthwork unloading analysis unit.

[0051] The earthwork loading analysis unit is used to obtain the loading process data parameters of each designated earthwork transport vehicle and analyze the loading process evaluation status of each designated earthwork transport vehicle.

[0053] It should be noted that the specific method for determining the stopping positioning deviation situation belonging to the evaluation situation of the loading process of each designated earth-moving transport vehicle is: comparing the stopping positioning deviation distance of the loading process of each designated earth-moving transport vehicle with the preset allowable stopping positioning deviation distance of the loading process of the earth-moving transport vehicle; if the stopping positioning deviation distance of the loading process of a designated earth-moving transport vehicle is greater than the preset allowable stopping positioning deviation distance of the loading process of the earth-moving transport vehicle, the stopping positioning deviation situation belonging to the evaluation situation of the loading process of the designated earth-moving transport vehicle is recorded as unqualified.

The permissible top earthwork protrusion height of the loading process of the preset earthwork transport trolley is used to further determine the loading condition to which the evaluation condition of the loading process of each designated earthwork transport trolley belongs.

[0055] It should be noted that the specific method for determining the loading condition to which the loading process evaluation condition of each designated earth-moving transport vehicle belongs is: comparing the loading evaluation indicators of the loading process of each designated earth-moving transport vehicle with the set loading evaluation indicator thresholds of the loading process; if the loading evaluation indicator of the loading process of a designated earth-moving transport vehicle is greater than the loading evaluation indicator threshold of the loading process, then the loading condition to which the loading process evaluation condition of the designated earth-moving transport vehicle belongs is recorded as unqualified.

[0056] A3. If the evaluation of the loading process of a designated earth-moving transport vehicle fails to meet the standards in the stop positioning deviation and the loading conditions, the evaluation of the loading process of the designated earth-moving transport vehicle is recorded as failed and corrective control is performed on it.

[0057] The control terminal is used to perform corrective control on each designated earth-moving transport vehicle with an unqualified evaluation result based on the evaluation result of the entire transportation process of each designated earth-moving transport vehicle.

[0058] As a preferred feasibility example, the specific content of the corrective control of each designated earth-moving transport vehicle with an unqualified evaluation result based on the evaluation result of the loading process of each designated earth-moving transport vehicle includes: if the stopping positioning deviation condition of the loading process evaluation result of a designated earth-moving transport vehicle is unqualified, the stopping position of the designated earth-moving transport vehicle is re-corrected.

If the earth-moving loading volume is unqualified, the earth-moving loading volume of the designated earth-moving transport vehicle will be corrected. If the protruding height of the top earth is unqualified, the top of the designated earth-moving transport vehicle will be flattened.

[0060] In a feasible specific example, the correcting of the earthwork load of the designated earthwork transport vehicle includes increasing the earthwork load or decreasing the earthwork load.

[0061] The transport process analysis unit is used to obtain the transport process data parameters of each designated earthwork transport vehicle and analyze the transport process evaluation status of each designated earthwork transport vehicle.

They are preset minimum values ​​that ensure the denominator is not 0, and their units are square meters and meters respectively.

[0065] B2. Determine the driving condition, posture condition and earth scattering condition of the transportation process evaluation of each designated earth-moving transport vehicle.

By comparing the number of transportation times in different time periods or by different vehicles, their working efficiency can be evaluated, thereby optimizing the transportation plan and resource allocation.

[0079] (2) The round trip time is an important indicator for measuring transportation efficiency. By recording and analyzing the round trip time, we can identify the key factors affecting transportation efficiency, such as road conditions, loading and unloading speeds, etc., so as to take targeted measures to improve them.
