In particular, the force transfer support assembly 11 includes a main beam 111 and several distribution beams 112. The distribution beams 112 are arranged in parallel, and two ends of the distribution beams 112 are respectively erected on the two rows of the buttresses 14.

One set of the set of distributed beam deformation data includes a number of distributed beam point deformation data for the same distributed beam 112. That is, distributed beam point deformation data of a plurality of points is collected on each distributed beam 112 to form a distributed beam deformation data set, so that a single distributed beam 112 is judged. In an actual operation, the upward deformation of the distribution beam 112 is a positive value, and the downward deformation of the distribution beam 112 is a negative value, for example, the deformation is positive when the platform is lifted. The number of the distributed beams 112 is n in total, and each distributed beam 112 is provided with m first deformation measuring devices 23, so that n groups of distributed beam deformation data sets are provided in total, and m distributed beam point deformation data are provided in each distributed beam deformation data set. The following were used:

……

N and m are positive integers, and the values of n and m can be selected by self according to specific conditions, are preferably odd numbers, and can record the deformation amount of the midpoint of the distribution beam 112. For convenience of explanation, the following description will be given by taking the case where n is 5 and m is 5 as an example.
Referring to fig. 4, the risk monitoring system 3 includes a data receiving module 31, a data processing module 32, and a risk judging module 33.
The data receiving module 31 is configured to receive each distribution beam deformation data set.
The data processing module 32 is configured to calculate respectively through each of the distributed beam deformation data sets to obtain an average value and a standard deviation of the distributed beam point deformation data of each of the distributed beams 112. Taking n as 5 and m as 5 as an example, the average values of the distributed beam point deformation data of 5 distributed beams 112 are:
the average value of the distributed beam point deformation data of the first distributed beam 112 is V1，
The average value of the distributed beam point deformation data of the second distributed beam 112 is V2，
The average value of the distributed beam point deformation data of the third distributed beam 112 is V3，
The average value of the distributed beam point deformation data of the fourth distributed beam 112 is V4，
The average value of the distributed beam point deformation data of the fifth distributed beam 112 is V5，
The risk judgment module 33 is configured to judge whether there is a risk of starting a platform according to the average value of the distributed beam point deformation data, and further judge whether there is a risk of overturning according to the standard deviation of the distributed beam point deformation data.
Specifically, in the risk judgment module 33, if the average value of the deformation data of any one of the distribution beam points is greater than zero and continuously increases, and cannot be stabilized within a predetermined time, there is a risk of starting a platform; if not, the risk of starting the platform does not exist. The predetermined time period may be set to 10 to 20 minutes, preferably 15 minutes. I.e., any one of the above average values is greater than zero and increases, indicating that the entire distribution beam 112 is deformed upward, i.e., moved upward, and if not stabilized, indicating that the upward movement is continued, which would lead to a landing accident if continued, and therefore, there is a risk of landing.
Similarly, in the risk judgment module 33, if the standard deviation of any one of the distribution beam point deformation data is greater than a first preset value, there is a risk of overturning; if not, there is no overturning risk. The first preset value is set to 10, and when the standard deviation of any distribution beam 112 is greater than 10, it indicates that the deformation of the distribution beam 112 is extremely unstable, and there is a risk of overturning. Taking n as 5 and m as 5 as an example, the standard deviation of the distributed beam point deformation data of 5 distributed beams 112 is:
the standard deviation of the distributed beam point deformation data of the first distributed beam 112 is σ1The calculation is as follows:
the standard deviation of the distributed beam point deformation data of the other distributed beams 112 is not listed here, and may be performed according to a formula of the standard deviation. The overall deformation of the distribution beam 112 is judged according to the standard deviation, and if the standard deviation is larger, the deformation is extremely unstable, and the risk of overturning exists.
Preferably, the data processing module 32 is further configured to calculate a tilt angle of the corresponding distribution beam 112 according to the endmost distribution beam point deformation data and the known length of the distribution beam 112. Taking the first distribution beam 112 as an example, the deformation data of the last distribution beam point is S15The length of the distribution beam 112 is L and the tilting angle is theta, then
From this equation, the value of θ can be obtained.
The risk determining module 33 is further configured to determine whether there is a risk of overturning according to the tilting angle, and if θ is larger, it indicates that the distribution beam 112 is inclined more greatly, and there is a risk of overturning. During specific judgment, the theta is compared with a second preset value, and if the tilting angle theta is larger than the second preset value, the overturning risk exists; if not, there is no overturning risk. The second preset value is set to be 8-12 degrees, preferably 10 degrees, and if the inclination angle of a certain distribution beam 112 is larger than 10 degrees, the existence of the overturning risk is judged.
Preferably, in order to timely notify the experimenter when judging that there is a risk of platform lift or overturning, and facilitate timely risk handling, the risk monitoring system 3 further includes a data transmitting module 34, where the data transmitting module 34 is configured to send early warning information to the corresponding terminal 5 when there is a risk of platform lift and/or overturning. The terminal 5 is a mobile phone or a tablet personal computer of an experimenter, and can directly send a short message or perform information reminding through application software loaded on the mobile phone or the tablet personal computer.
In addition, in order to facilitate the ordinary checking and supervision of the tester, the risk monitoring system 3 further includes a display device 35 for displaying the distribution beam deformation data group corresponding to each distribution beam 112 and the average value and the standard deviation of the corresponding distribution beam point deformation data in real time, so that the tester can visually see the deformation condition of the distribution beam 112, and the tester can comprehensively know the safety state of the static load test bed and adjust and early warn the next static load test.
Preferably, the deformation measurement system 2 further includes a main beam monitoring group 22, the main beam monitoring group 22 includes a plurality of second deformation measurement devices 24, each of the second deformation measurement devices 24 is disposed at equal intervals along the length direction of the main beam 111 and is respectively connected to the main beam 111, and collects and sends main beam point deformation data of a connection point with the main beam 111 in real time. The second deformation measuring device 24 can be provided in a plurality, for example 3, 4, 5 or 6, or even more, the number being chosen according to the specific situation. The main beam 111 is also stressed in the experiment, and is also deformed correspondingly, similar to the distribution beam 112, the overall situation can be known by collecting deformation data of the main beam points, and whether the platform rises or not is judged (because the platform is in the middle, the platform is not easy to overturn). Taking 5 second deformation measuring devices 24 arranged on the main beam 111 as an example, the deformation data of the 5 main beam points are respectively: s01、S02、S03、S04And S05。
The deformation data further comprises a main beam deformation data group, wherein the main beam deformation data group comprises deformation data of each main beam point, namely the deformation data comprises the S01、S02、S03、S04And S05。
The data receiving module 31 is further configured to receive the main beam deformation data set.
The data processing module 32 is further configured to obtain an average value V of the deformation data of the main beam point through calculation of the main beam deformation data group0，
And the risk judgment module 33 is further configured to judge whether there is a risk of landing according to the average value of the deformation data of the main beam point. Similar to the typhoon starting risk judgment of the distribution beam 112, in the risk judgment module 33, if the average value of the deformation data of the main beam 111 is larger than zero and continuously increases and cannot be stabilized within a preset time, the typhoon starting risk exists; if not, the risk of starting the platform does not exist. The predetermined time period may be set to 10 to 20 minutes, preferably 15 minutes. That is, the average value of the deformation data of the main beam 111 is larger than zero and is continuously increased, which indicates that the main beam 111 is deformed upwards as a whole, that is, moves upwards as a whole, and if the main beam is unstable, indicates that the main beam 111 continues to move upwards, which causes a landing accident, and therefore, the main beam has a landing risk.

The rotation angle of the drum 232 is measured, and since the measuring line 233 is wound on the drum 232, the retraction of the measuring line 233, i.e. the deformation of the distribution beam 112 or the main beam 111, can be calculated according to the radius r of the drum 232.
And the processor is electrically connected with the angle sensor 234 and calculates and obtains the distributed beam point deformation data or the main beam point deformation data according to the radius and the rotation angle data. The specific calculation is as follows: l is r · α, L is an arc length, r is a radius of the drum 232, α is a center angle through which the drum 232 rotates, the deformation measurement wire is wound around the drum 232, and a change value of the measurement line 233, that is, the distribution beam point deformation data or the main beam point deformation data, can be calculated according to the angle sensor 234.
And a data transmission unit 235 electrically connected to the processor, for outputting the distributed beam point deformation data or the main beam point deformation data. The data transmission unit 235 may be a wired output or a wireless output. Preferably, the data transmission unit 235 is a wireless signal transmitting device, such as a bluetooth module or a GPRS module, and the data receiving module 31 can receive the data. It should be noted that it is a conventional technical means in the art to connect the processor and the angle sensor 234 and process data, and it is also a conventional technical means in the art to connect the bluetooth module or the GPRS module to the processor and output data, so the specific connection manner and model thereof will not be described herein, and those skilled in the art can select and connect the appropriate processor, angle sensor 234, bluetooth module and GPRS module according to the required functions, as long as the above functions can be achieved.
One end of the elastic reset element 236 is fixedly connected to the housing 231, and the other end is fixedly connected to the winding drum 232. When the measuring line 233 is pulled out, the elastic resetting element 236 is stretched and stored energy, after the distribution beam 112 or the main beam 111 is deformed, the elastic resetting element 236 retracts, and the measuring line 233 keeps straight when the winding drum 232 rotates, so that the accuracy of measuring the deformation amount is ensured. In particular, the elastic return element 236 is a spring with damping, which can avoid the influence on the precision caused by too fast pulling out and retracting.
Based on the above structure, when performing deformation measurement, the housing 231 is placed on the ground, the measuring wire 233 is pulled out, and is fixed with the distribution beam 112 or the main beam 111 to be measured through the fixing portion 2331 of the measuring wire 233, at this time, the measuring wire 233 is stretched under the action of the elastic reset element 236; after the experiment begins, the length of the pulling-out measuring line 233 changes due to the deformation of the distribution beam 112 or the main beam 111, the reel 232 rotates due to the pulling-out change of the measuring line 233, the angle sensor 234 detects the rotation angle of the reel 232, calculates the deformation amount (i.e., the distribution beam point deformation data or the main beam point deformation data) by combining the known radius through the processor, outputs the deformation amount by the data transmission part 235, receives the deformation amount by the data receiving module 31, and finally displays the risk judgment result to the testing personnel by the risk monitoring system 3. The first deformation measuring device 23 and/or the second deformation measuring device 24 can be mounted by only fixing the fixing portion 2331 to the distribution beam 112 or the main beam 111, and can be dismounted by only detaching the fixing portion 2331 from the distribution beam 112 or the main beam 111, which is very convenient.
In addition, the first deformation measuring device 23 and/or the second deformation measuring device 24 further include an adhesive hook 237, the adhesive hook 237 includes an adhesive plate 2371 and a hook 2372 fixed on one side of the adhesive plate 2371, and one side of the adhesive plate 2371 facing away from the hook 2372 is provided with an adhesive layer; the fixing portion 2331 has a hole through which the hook 2372 passes and is hooked. The sticky hook 237 can be fixed on the distribution beam 112 or the main beam 111 by the sticky layer, and then fixed with the fixing part 2331 by the hook 2372, so that the measurement line 233 is further convenient to be connected and fixed with the distribution beam 112 or the main beam 111, the installation is more convenient, the measurement line 233 can be directly taken down and the sticky layer can be uncovered when the detachment is needed, and the detachment is also more convenient. The fixing portion 2331 is a circular ring, and may be a metal ring, such as an iron ring.
