Description

Technical Field

[0001] This invention relates to the field of safety monitoring technology, specifically to a device and method for monitoring the tilt of beam-supported columns. Background Technology

[0002] When there is a need to transport steel trusses during the construction of long-span steel truss bridges, temporary trestle bridges are usually erected and steel truss trolleys are used to transport the steel trusses. In actual projects, the timing and frequency of lifting the steel trusses (from the beam yard to the construction site) and erecting the steel trusses (after the steel trusses are erected) are different. In order to ensure a tight construction schedule, the lifting of the steel trusses usually occurs earlier than the transport, and the frequency of lifting the steel trusses is also higher. Therefore, temporary storage positions are reserved on the transport trestle bridge, and storage columns are set up at the corresponding positions as support columns for the temporary storage of the steel trusses.

[0003] Due to the limited space on the beam transport trestle, the safety clearance between the beam transport trolley and the beam storage columns is very small, which can lead to several safety issues: 1. During beam transport, the storage columns may tilt due to uneven settlement, thus obstructing the passage of the beam transport trolley; 2. The storage columns may deform excessively under stress, posing a risk of overturning and affecting the support of the steel truss girder. Therefore, it is necessary to adopt some simple and feasible monitoring methods to monitor the tilting and settlement of the storage columns, thereby ensuring the safety of beam transport and storage during construction. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, the purpose of this invention is to provide a device and method for monitoring the tilt of the beam storage column, so as to solve the safety problem of the beam transport trolley being affected by the tilt of the beam storage column during the beam transport process, and to adjust the tilt angle of the beam storage column in a timely and accurate manner.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] On the one hand, this application provides a device for monitoring the tilt of a beam-supported column, comprising:

[0007] At least one rangefinder is provided on the beam transport trolley to measure the distance between the beam transport trolley and each beam storage column as the beam transport trolley passes by each beam storage column.

[0008] The processor, which is connected to the rangefinder signal, is used to obtain the minimum distance measured by the rangefinder when it passes each of the beam storage columns, and, in combination with the set distance between the beam transport trolley and the beam storage column and the vertical distance from the rangefinder to the beam transport trestle, determine the tilt angle of the beam storage column in the transverse direction of the bridge.

[0009] In some optional embodiments, the processor is further configured to acquire the time difference between the start and end data of the rangefinder passing each of the beam storage columns, and, in conjunction with the speed of the beam transport trolley and the longitudinal width of the beam storage column, determine the tilt angle of the beam storage column in the longitudinal direction.

[0010] In some optional embodiments, an alarm is also included, which is installed on each of the aforementioned beam storage columns and signal-connected to the aforementioned processor, for triggering an alarm when the tilt angle of the aforementioned beam storage column in the transverse and / or longitudinal directions exceeds a corresponding set value.

[0011] In some optional embodiments, a card reader connected to the processor and a tag card for each of the above-mentioned beam storage columns are also included. The card reader is used to match the information processed by the processor with the tag card information of the corresponding beam storage column.

[0012] On the other hand, a method for monitoring the tilt of beam-supporting columns is also provided, implemented using the aforementioned device, comprising the following steps:

[0013] The minimum distance between the beam transport trolley and each beam storage column is measured when the beam transport trolley passes by each beam storage column;

[0014] Based on the minimum distance mentioned above, and combined with the set spacing between the beam transport trolley and the beam storage column, as well as the vertical distance from the rangefinder to the beam transport trestle, the tilt angle of the beam storage column in the transverse direction of the bridge is determined.

[0015] In some alternative embodiments, determining the tilt angle of the aforementioned beam-holding column in the transverse direction includes:

[0016] according to The tilt angle θ1 of the aforementioned beam storage column in the transverse direction is determined, where L is the predetermined distance between the aforementioned beam transport trolley and the aforementioned beam storage column. min H is the minimum distance between the beam transport trolley and the beam storage column measured by the aforementioned distance measuring instrument, and H is the vertical distance from the aforementioned distance measuring instrument to the beam transport trestle.

[0017] In some optional embodiments, when the beam transport trolley passes each beam storage column, the time difference between the start data and the end data of the rangefinder passing each beam storage column is obtained. Combined with the speed of the beam transport trolley and the width of the beam storage column in the longitudinal direction of the bridge, the tilt angle of the beam storage column in the longitudinal direction of the bridge is determined.

[0018] In some optional embodiments, determining the inclination angle of the aforementioned beam-holding column in the longitudinal direction of the bridge includes:

[0019] according to Determine the inclination angle θ2 of the above-mentioned beam storage column in the transverse direction of the bridge, where L0 is the width of the above-mentioned beam storage column in the longitudinal direction of the bridge, v is the speed of the above-mentioned beam transport trolley, and t is the time difference between the starting data and the ending data of the above-mentioned rangefinder passing through each of the above-mentioned beam storage columns.

[0020] In some alternative embodiments, the device further includes an alarm for installation on each of the aforementioned beam storage columns and signal connection to the aforementioned processor, which triggers an alarm when the tilt angle of the beam storage column in the transverse and / or longitudinal direction exceeds a corresponding set value.

[0021] In some alternative embodiments, the device further includes a card reader connected to the processor and a tag card for placement on each of the aforementioned storage beam columns.

[0022] After measuring the distance between the beam-carrying trolley and each beam-storage column as it passes by, the following steps are also included:

[0023] The card reader matches the information measured by the rangefinder with the marking card information of the corresponding storage beam column.

[0024] Compared with the prior art, the advantages of the present invention are as follows: By using a rangefinder, the distance between the beam-carrying trolley and the beam-carrying column is measured during the movement of the beam-carrying trolley on the beam-carrying trestle. Combined with the set distance between the beam-carrying trolley and the beam-carrying column and the vertical distance from the rangefinder to the beam-carrying trestle, the tilt angle of the beam-carrying column in the transverse direction can be determined. This allows for real-time monitoring of the tilt of the beam-carrying column and adjustment of the corresponding column according to the tilt angle, preventing the beam-carrying column from tilting and affecting the safety of the beam-carrying trolley. Furthermore, the monitoring method is simple; a single rangefinder can monitor the tilt of a group of beam-carrying columns, making it easy to implement. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] On the one hand, such as Figure 1 As shown, this application provides a device for monitoring the tilt of beam storage columns, including a rangefinder 2 and a processor. When the rangefinder 2, which is installed on the beam transport trolley 1, travels on the beam transport trestle 4, it measures the distance of the beam storage columns 3 located on both sides of the beam transport trestle 4. After processing by the processor, the tilt of each beam storage column 3 is monitored and timely adjustments are made to improve the safe driving of the beam transport trolley 1 and the normal operation of the beam storage columns 3.

[0032] Specifically, the distance measuring instrument 2 is installed on the beam transport trolley 1 to measure the distance between the beam transport trolley 1 and each beam storage column 3 when the beam transport trolley 1 passes by each beam storage column 3; the processor is signal-connected to the distance measuring instrument 2 to obtain the minimum distance measured by the distance measuring instrument 2 when passing by each beam storage column 3, and, in combination with the set spacing between the beam transport trolley 1 and the beam storage column 3 and the vertical distance from the distance measuring instrument 2 to the beam transport trestle 4, to determine the tilt angle of the beam storage column 3 in the transverse direction of the bridge.

[0033] It is understandable that a girder transport trestle is a temporary facility used in bridge construction for short-distance transportation of large girder sections. The trestle is typically divided into two symmetrical sections, left and right. In this example, the trestle serves as both a transport channel and a temporary storage location for the steel truss girders. Specifically, both trestle sections 4 are approximately 1 kilometer long. On each side of the trestle section 4, 20 temporary girder storage points are spaced longitudinally along the bridge. Each storage point is equipped with a support column 3 to support the steel truss girder. Each trestle section 4 is equipped with a trolley 1 for transporting the steel truss girder. During transport, the two trolleys move side-by-side, working together to transport and store the steel truss girder. The gap between the trolley and the support column is relatively small. Due to settlement and other factors, the support column may tilt, posing a collision risk not only to the trolley but also to the storage of the steel truss girder, potentially leading to instability, uneven stress, deformation, or collapse.

[0034] Therefore, to improve the safety of the beam transport trolley and the support stability of the steel truss girder, at least one distance measuring instrument 2 is installed on the side of the beam transport trolley 1 closest to the beam storage column 3. In this example, two distance measuring instruments 2 are symmetrically installed on the beam transport trolley 1, located on both sides of the beam transport trolley 1 closest to the beam storage column 3. When the beam transport trolley 1 passes each beam storage column 3, the distance measuring instrument 2 starts measuring. The processor combines the measured minimum distance value with the set distance between the beam transport trolley 1 and the beam storage column 3 and the vertical distance from the distance measuring instrument 2 to the beam transport trestle 4 to determine the tilt angle of the beam storage column 3 in the transverse direction of the bridge. This allows for timely monitoring of the tilt angle of each beam storage column in the transverse direction, and timely adjustments can be made to the beam storage columns based on the tilt angle.

[0035] Here, the aforementioned set distance is the initial distance between the beam transport trolley 1 and the beam storage column 3 after the construction is completed. That is, the distance between the beam storage column 3 and the beam transport trolley 1 under the construction requirements. Later, when the beam storage column 3 tilts, it will be adjusted in the opposite direction according to the tilt angles in the transverse and longitudinal directions of the bridge to meet the initial state of the set distance.

[0036] Furthermore, the processor is also used to acquire the time difference between the start data and the end data of the rangefinder 2 passing through each of the beam storage columns 3, and, in combination with the speed of the beam transport trolley 1 and the width of the beam storage column 3 in the longitudinal direction, to determine the tilt angle of the beam storage column 3 in the longitudinal direction.

[0037] When the beam transport trolley 1 travels on the beam transport trestle 4, it passes each beam storage column 3 in sequence. The distance measuring instrument 2 begins measuring as it passes the corresponding beam storage column 3. The beam storage column 3 has a set width in the longitudinal direction of the bridge. Therefore, the processor acquires multiple sets of data when passing through this set width. After filtering out the starting and ending data for passing through the beam storage column 3 and obtaining the time difference between the two measurements, it combines the speed of the beam transport trolley 1 and the longitudinal width of the beam storage column 3 to determine the tilt angle of the beam storage column 3 in the longitudinal direction of the bridge.

[0038] The travel speed of the beam transport trolley 1 on the beam transport trestle 4 can be specifically set based on the processor's ability to acquire the measurement values ​​from the rangefinder 2 and the width of the beam storage column 3 along the longitudinal direction of the bridge.

[0039] Therefore, when the beam transport trolley 1 passes each beam storage column 3, it can measure the tilt angle of the beam storage column 3 along both the transverse and longitudinal directions of the bridge, thereby accurately monitoring the condition of each beam storage column.

[0040] In this example, the rangefinder 2 can be a laser rangefinder, with the laser emission direction along the transverse bridge and kept horizontal.

[0041] Using a rangefinder to monitor the tilt of the beam storage column 3 is a simple method; one rangefinder can monitor the tilt of a group of beam storage columns 3.

[0042] In some optional embodiments, the tilt angles of the beam-storing column 3 in the transverse and longitudinal directions obtained after the data collected by the processor are processed by the processing module are displayed through the output device. This can better meet the needs of monitoring personnel for quick and accurate reading of monitoring results, and also facilitate accurate adjustment of the tilt of the beam-storing column based on the output results.

[0043] In some optional embodiments, the above-mentioned device further includes an alarm, which is installed on each of the above-mentioned beam storage columns 3 and is signal-connected to the processor, for triggering an alarm when the tilt angle of the above-mentioned beam storage column 3 in the transverse and / or longitudinal directions exceeds a corresponding set value.

[0044] To enable more intuitive and timely detection and handling of the tilting of the beam storage column 3, an alarm is installed on each beam storage column 3. When the tilting angle of the beam storage column 3 in the transverse and / or longitudinal direction exceeds the corresponding set value, the alarm will sound, and the monitoring personnel can immediately take corresponding measures, such as stopping the passage of the beam transport trolley. After reading the tilting direction and angle of the beam storage column, timely correction can be made according to the above parameters. After correction, the beam transport trolley can be restarted only after ensuring safe passage.

[0045] Of course, the processor's storage device can also be used to store the data measured by the rangefinder during each trip of the beam transport trolley, so as to observe the positional changes of all the beam storage columns during the back-and-forth movement of the beam transport trolley on the trestle, which can also serve as a reference for the safety of bridge construction.

[0046] In some optional embodiments, the above-mentioned device further includes a card reader connected to the processor and a tag card for being disposed on each of the above-mentioned beam storage columns 3. The card reader is used to match the information processed by the processor with the tag card information of the corresponding beam storage column 3.

[0047] To facilitate better monitoring of the tilt of each beam storage column and to effectively store the data measured by the rangefinder during each beam transport trolley trip, thereby improving monitoring effectiveness, a marker card is set on each beam storage column 3. Before the beam transport trolley 1 passes the beam storage column 3 and the rangefinder 2 begins measuring the distance between the beam transport trolley 1 and the beam storage column 3, the card reader reads the information on the marker card on the beam storage column 3. The reader then processes all the data measured by the rangefinder 2 on the beam storage column 3, determines the tilt angle, and matches it with the information on the marker card on the beam storage column for easy classification and storage.

[0048] On the other hand, this application also provides a method for monitoring the tilt of beam-supporting columns, implemented using the aforementioned device, comprising the following steps:

[0049] S1: Measure the minimum distance between the beam transport trolley 1 and each beam storage column 3 when the beam transport trolley 1 passes by each beam storage column 3.

[0050] Understandable, such as Figure 2 As shown, when the beam transport trolley 1 passes a beam storage column 3, the distance measuring instrument 2 passes through the beam storage column 3 and begins to measure the distance between the beam transport trolley 1 and the beam storage column 3. During the time period of passing through the beam storage column 3, the processor acquires data measured by multiple distance measuring instruments 2, and after filtering, obtains the minimum distance between the beam transport trolley 1 and the beam storage column 3.

[0051] S2: Based on the minimum distance mentioned above, and combined with the set distance between the beam transport trolley 1 and the beam storage column 3 and the vertical distance from the rangefinder 2 to the beam transport trestle 4, determine the tilt angle of the beam storage column 3 in the transverse direction of the bridge.

[0052] Specifically, determining the inclination angle of the aforementioned beam support column 3 in the transverse direction of the bridge includes:

[0053] according to The tilt angle θ1 of the aforementioned beam storage column 3 in the transverse direction is determined, where L is the initial distance between the aforementioned beam transport trolley 1 and the aforementioned beam storage column 3. min H is the minimum distance between the beam transport trolley 1 and the beam storage column 3 measured by the distance measuring instrument 2, and H is the vertical height from the distance measuring instrument 2 to the beam transport trestle 4.

[0054] In some optional embodiments, when the beam transport trolley 1 passes each beam storage column 3, step S1 further includes: obtaining the time difference between the start data and the end data of the rangefinder 2 passing each beam storage column 3, and determining the tilt angle of the beam storage column 3 in the longitudinal direction by combining the speed of the beam transport trolley 1 and the width of the beam storage column 3 in the longitudinal direction.

[0055] Specifically, according to Determine the inclination angle θ2 of the above-mentioned beam storage column 3 in the transverse direction of the bridge, where L0 is the width of the above-mentioned beam storage column 3 in the longitudinal direction of the bridge, v is the speed of the above-mentioned beam transport trolley 1, and t is the time difference between the starting data and the ending data of the above-mentioned rangefinder 2 passing through each of the above-mentioned beam storage columns 3.

[0056] Understandable, such as Figure 3As shown, the beam storage column 3 has a fixed width in the longitudinal direction of the bridge. Therefore, the processor will acquire multiple sets of data when passing through this actual width. For example, the processor acquires the data measured by the distance measuring instrument 2 every 10 milliseconds. The time required for the distance measuring instrument 2 on the beam transport trolley 1 to completely pass through a beam storage column 3 is one second. Then, the processor can acquire 100 measured spacing values ​​when the distance measuring instrument passes through the beam storage column. At this time, the actual width of the tilted beam storage column 3 in the longitudinal direction is L'0 = v·t, which can be calculated according to... The value of θ2 is calculated.

[0057] By filtering to obtain the minimum spacing and acquiring the time difference between the starting and ending data, combined with the speed of the beam transport trolley 1 and the longitudinal width of the beam storage column 3, the tilt angles θ1 and θ2 of the beam storage column in the transverse and longitudinal directions can be determined.

[0058] It should be noted that the travel speed of the beam transport trolley can be determined based on the processor's acquisition capabilities and measurement accuracy. No specific restrictions are imposed in this application, and those skilled in the art can make corresponding choices based on construction requirements.

[0059] In some alternative embodiments, the device further includes an alarm for installation on each of the aforementioned beam storage columns 3 and for signal connection to the aforementioned processor, which alarms when the tilt angle of the aforementioned beam storage column 3 in the transverse and / or longitudinal directions exceeds a corresponding set value.

[0060] It is understandable that the alarm will sound if the tilt angle of the beam storage column 3 exceeds the corresponding set value in either the longitudinal or transverse direction of the bridge, so as to correct the position of the beam storage column in time and prevent the occurrence of safety accidents.

[0061] In some alternative embodiments, the device further includes a card reader connected to the processor and a tag card for placement on each of the aforementioned storage beam columns 3.

[0062] After measuring the distance between the beam transport trolley 1 and the beam storage column 3 as it passes each beam storage column 3, the following steps are also included:

[0063] S3: The card reader will match the information processed by the processor with the marking card information of the corresponding storage beam column 3.

[0064] For example, if the processor acquires data from the distance measuring device 2 every 10 milliseconds, and the distance measuring device 2 on the beam transport trolley 1 takes one second to completely pass a beam storage column 3, then the processor can acquire 100 measured spacing values ​​when the distance measuring device passes the column. When the beam transport trolley passes a beam storage column, the card reader scans the information on the marker card on the column and matches the set of tilt angles in the transverse and longitudinal directions corresponding to the data acquired by the processor with the marker card information and stores it in the storage device. By acquiring and storing the position status of each beam storage column when the beam transport trolley travels along the longitudinal direction once, the status of each beam storage column can be better monitored, which is also of reference value for bridge construction.

[0065] In some optional embodiments, after the card reader reads the marking card on the corresponding storage beam column 3, the rangefinder 2 starts measuring and feeds back the measurement data to the processor.

[0066] In other embodiments, the rangefinder 2 continuously maintains a measurement state, and the processor filters all the data measured by the rangefinder 2 and matches it with the corresponding tag card information.

[0067] For example, the set distance (i.e., the initial distance) between the beam transport trolley 1 and the beam storage column 3 is 30cm. When the rangefinder 2 moves with the beam transport trolley 1 on the beam transport bridge 4 and passes each beam storage column 3 in sequence, the processor filters the data greater than 30cm measured by the rangefinder 2, retaining the data less than or equal to 30cm. It then matches a series of consecutive measurements less than or equal to 30cm with the information on the corresponding marker card on the beam storage column. The minimum value in this set of data is then selected and sent to the processor's processing module for calculation and analysis to obtain the tilt angle of the beam storage column. This angle also serves as the effective actual distance value of the beam storage column during this beam transport trolley operation and is stored in the processor's storage module.

[0068] Of course, the rangefinder can also be configured to only send feedback to the processor when the data measured by the rangefinder is within a set range, and the processor will then filter and process all the data obtained.

[0069] In other embodiments, the initial distance between the beam transport trolley 1 and the beam storage column 3 can be other values, which can be selected by those skilled in the art according to actual requirements and working conditions.

[0070] This application discloses a device and method for detecting the tilt of beam storage columns. By installing a rangefinder on the beam transport trolley, the minimum distance between the trolley and each storage column is measured as the trolley passes. The tilt angle of the storage column in the transverse direction is determined by combining the set distance between the trolley and the column, the vertical distance from the rangefinder to the transport trestle, and the time difference between the start and end data of the rangefinder passing each column. Combined with the speed of the trolley and the longitudinal width of the column, the tilt angle in the longitudinal direction is determined. This allows for the detection of the condition of each storage column during the operation of the trolley. The acquired tilt angle can be adjusted in a timely manner. The method is simple: a single rangefinder can monitor the tilt of a group of beam storage columns, making it easy to implement. By setting an alarm on each beam storage column, the tilt of the columns can be detected and addressed more intuitively and promptly. By setting a marker card on each column, the tilt angle determined by processing all the data measured by the rangefinder on that column is matched with the information on the marker card, which facilitates better monitoring of the tilt of each column. Furthermore, the data measured by the rangefinder during each beam transport trolley trip is effectively stored to improve the effectiveness of the monitoring.
