Figure 4 A schematic diagram for use in strength testing of prefabricated components with inclined surfaces, such as prefabricated ditches, prefabricated slopes, prefabricated stairs, etc.

[0023] Specifically, Figures 1 to 4 As shown, the assembled prefabricated component strength detection device provided by the embodiment of the present invention includes a bearing platform 10, a gantry 20, a mounting assembly 30 and a loading assembly 40. The bearing platform 10 has a horizontal support table 11; the gantry 20 is arranged on the bearing platform 10, and the top of the gantry 20 has a horizontal first track; the mounting assembly 30 includes a sliding frame 31, a mounting bracket 32, a first driving member 33 and a transmission rod 34, the sliding frame 31 is movably arranged on the first track, the mounting bracket 32 ​​is rotatably arranged on the sliding frame 31, the first driving member 33 is arranged on the sliding frame 31, and is used to drive the mounting bracket 32 ​​to rotate around an axis perpendicular to the length direction of the first track, the transmission rod 34 is vertically arranged on the mounting bracket 32 ​​downward, and the bottom of the transmission rod 34 is also provided with a mounting plate 33. 41, the mounting plate 341 has a mounting groove 3411 that passes through in the vertical direction; the loading assembly 40 includes a first lifting rod 41 and a pressure loading unit 42, the pressure loading unit 42 includes a pressure block 421 that is slidably arranged in the mounting groove 3411 in the vertical direction, and a first spring 422, the first spring 422 is arranged between the mounting plate 341 and the pressure block 421, and is configured with a preload force that moves the pressure block 421 upward; the first lifting rod 41 is vertically downwardly arranged on the mounting bracket 32, and is located above the pressure block 421, and a pressure sensor 411 is provided at the bottom of the first lifting rod 41.

[0024] Compared with the prior art, the advantageous effects of the prefabricated component strength detection device provided by the embodiment of the present invention are: The assembled prefabricated component strength detection device provided by the embodiment of the present invention includes a bearing platform 10, a gantry 20, a mounting assembly 30 and a loading assembly 40. The gantry 20 is arranged on the bearing platform 10, and the mounting assembly 30 can move along the first track to adjust its own position. The loading assembly 40 is arranged on the mounting bracket 32, and the loading assembly 40 includes a first lifting rod 41 and a pressure loading unit 42. When it is necessary to perform strength detection on the prefabricated component, the prefabricated component is first stably placed on the support table 11, and then the angle of the mounting bracket 32 ​​is adjusted by the first driving member 33 so that the loading assembly 40 can act vertically on the surface to be detected of the prefabricated component. Subsequently, the first lifting rod 41 moves downward, pushing the pressure block 421 of the pressure loading unit 42 to overcome the preload force of the first spring 422 and press against the prefabricated component until the pressure value of the pressure sensor 411 reaches a preset value. The static pressure applied to the prefabricated component is maintained for a period of time by the first lifting rod 41, and then the detection is completed.

[0025] In the embodiment of the present invention, the mounting bracket 32 ​​is rotatably arranged on the sliding frame 31. When the prefabricated component is a component with an inclined surface such as a prefabricated side channel 80 or a prefabricated staircase, the angle of the mounting bracket 32 ​​can be adjusted by the first driving member 33 to ensure that the force of the first lifting rod 41 and the pressure loading unit 42 is perpendicular to the surface to be tested of the prefabricated component. Figure 4 The prefabricated side ditch 80 shown hereby improves the accuracy of strength testing.

[0026] The loading platform 10 has a support table 11 for placing the prefabricated components to be tested. In actual operation, the prefabricated components can be placed on the support table 11 by hoisting. When the support table 11 is large in area, multiple prefabricated components to be tested can be placed on it to improve the testing efficiency. When the prefabricated components are special-shaped parts, bricks, support rods, etc. can be used to provide auxiliary support for the prefabricated components to ensure that the prefabricated components are stable during strength testing.

[0027] See also Figure 1 and Figure 2 The carrier 10 is provided with a second track 12 on both sides of the support table 11, and the length direction of the second track 12 is perpendicular to the length direction of the first track. The bottom of the gantry 20 is provided with a moving wheel 21, which can move along the second track 12. During the test, multiple prefabricated components to be tested can be placed on the support table 11, and the gantry 20 moves along the second track 12 to test the multiple prefabricated components in turn. Alternatively, when the prefabricated component is a prefabricated concrete slab 70, the length of the prefabricated component is relatively long, and multiple detection points need to be selected. The gantry 20 can be controlled to move along the second track 12 to detect multiple position points of the prefabricated concrete slab 70.

[0028] The mounting assembly 30 includes a sliding frame 31, a mounting bracket 32, a first driving member 33 and a transmission rod 34. The first driving member 33 can be a reduction motor, a hydraulic motor, etc., which can drive the mounting bracket 32 ​​to rotate, thereby changing the angle of the loading assembly 40 to adapt to inclined surfaces with different inclination angles. The lower part of the transmission rod 34 is connected to a mounting plate 341, and a pressure loading unit 42 is arranged on the mounting plate 341. When performing a strength test, the first lifting rod 41 descends and transmits the pressure to the prefabricated component through the pressure loading unit 42. The first lifting rod 41 can be a hydraulic lifting cylinder. A pressure sensor 411 is provided between the first lifting rod 41 and the pressure block 421. The pressure sensor 411 can detect the static pressure value applied by the first lifting rod 41 to the pressure block 421.

[0029] After the inspection is completed, the first lifting rod 41 rises, and the first spring 422 drives the pressure block 421 to reset upward. The inspector evaluates whether the strength of the prefabricated component is qualified by checking whether there are pits, cracks, etc. on the surface of the prefabricated component.

[0030] Optionally, according to different detection requirements, multiple pressure blocks 421 can be provided in different shapes and sizes. The pressure block 421 can be detachably provided on the mounting plate 341. According to different prefabricated components, the pressure block 421 compatible with it can be replaced.

[0031] In the above embodiment, due to the various shapes and sizes of prefabricated components, the stroke of the first lifting rod 41 each descent is different during testing. A part of the force Fn generated when the first lifting rod 41 descends is used to overcome the preload force of the first spring 422, which is defined as F1, and the other part is applied to the surface of the prefabricated component through the pressure block 421, which is defined as F2. When testing prefabricated components of different shapes, thicknesses, and sizes, the F1 shown is changed due to the different degrees of compression of the first spring 422. In this way, it is impossible to accurately know the static pressure F2 applied to the prefabricated component.

[0032] To solve the above problems, see Figure 3 , Figure 5 and Figure 6 In some possible embodiments, the loading assembly 40 further includes a force transmission unit 43, which includes a first connecting rod 4321, a force transmission block 432, and a second spring 433. The first connecting plate 431 is disposed on the first lifting rod 41 and is located above the pressure sensor 411; the force transmission block 432 is disposed below the pressure sensor 411, and a connecting rod 4321 is disposed on the top of the force transmission block 432, and the connecting rod 4321 is slidably matched with the first connecting plate 431; the second spring 433 is disposed between the force transmission block 432 and the first connecting plate 431, and the elastic stiffness coefficient of the second spring 433 is greater than the stiffness coefficient of the first spring 422, that is, the first spring 422 is relatively soft, and the second spring 433 is relatively hard.

[0033] In this embodiment, the force transmission unit 43 is provided so that the loading assembly 40 has an in-place detection function. Specifically, when pressure is applied to the prefabricated component, the first lifting rod 41 moves downward first, driving the force transmission block 432 downward to abut against the pressure block 421. Since the first spring 422 is relatively soft, the first spring 422 is compressed first until the pressure block 421 abuts against the point to be detected of the prefabricated component. At this time, due to the existence of the second spring 433, the pressure sensor 411 has not yet abutted against the force transmission block 432, and the pressure value of the pressure sensor 411 is zero.

[0034] Then the first lifting rod 41 continues to move downward, and the second spring 433 is compressed until the pressure sensor 411 abuts against the force transmission block 432. When the pressure sensor 411 senses the pressure value, it indicates that the pressure block 421 abuts against the position to be tested of the prefabricated component. Finally, the first lifting rod 41 continues to apply downward pressure, and the pressure is transmitted to the point to be tested of the prefabricated component through the pressure sensor 411, the force transmission block 432 and the pressure block 421.

[0035] The pressure block 421 and the force transmission block 432 are both metal blocks such as cast iron, carbon steel, etc., which can be regarded as rigid components and do not deform when subjected to force. With such an arrangement, the sum of the detection value of the pressure sensor 411 and the elastic force generated by the compression of the second spring 433 is approximately equal to the static pressure value applied by the pressure block 421 to the prefabricated component, eliminating the force error caused by the different degrees of compression deformation of the first spring 422, making the test result more accurate.

[0036] See also Figure 5 In some possible embodiments, the loading assembly 40 further includes a deformation detection unit, which includes a first distance sensor 44 provided on the connecting rod 4321, for detecting the displacement stroke of the first lifting rod 41. The first distance sensor 44 and the second distance sensor 64 described below can use existing distance measuring products on the market, and there is no restriction on their specific specifications and models. For example, the distance measuring range can be 10-100mm, and the distance measuring accuracy is 0.1mm. The displacement stroke of the first lifting rod 41 is detected by the first distance sensor 44, and then the deformation of the prefabricated component under a certain static pressure is determined. When the deformation exceeds the prefabricated value, the strength of the position is determined to be unqualified.

[0037] Specifically, when the pressure sensor 411 generates a pressure value, the controller determines that the pressure block 421 has abutted against the prefabricated component. The controller controls the first lifting rod 41 to apply static pressure to the pressure sensor 411 until it reaches a preset value, and maintains the preset pressure value for a period of time. At this time, the reading L1 of the first distance measuring sensor 44 is recorded. If the prefabricated component is deformed, in order to ensure that the pressure value applied to the prefabricated component remains unchanged, the first lifting rod 41 will continue to descend, and the reading L2 of the first distance measuring sensor 44 is recorded at this time. The difference between L2 and L1 is the deformation of the prefabricated component. The controller can automatically calculate the value of the deformation, and determine whether the deformation is within the qualified range, and then determine whether the strength of the position point is qualified.

[0038] See also Figure 5 and Figure 6In some possible embodiments, the transmission rod 34 is rotatably arranged on the mounting bracket 32, the transmission rod 34 is a telescopic member, and the mounting assembly 30 further includes a second driving member 35, which is used to drive the transmission rod 34 to rotate around the vertical axis. The assembled prefabricated component strength detection device further includes a marking assembly 50, and the marking assembly 50 includes a qualified position point marking unit 51 and an unqualified position point marking unit 52. The qualified position point marking unit 51 is arranged on the mounting plate 341, and is used to mark the qualified points of the test strength; the unqualified position point marking unit 52 is arranged on the mounting plate 341, and is used to mark the unqualified points of the test strength. Among them, the qualified position point marking unit 51, the unqualified position point marking unit 52 and the pressure loading unit 42 are arranged at intervals along the circumference of the mounting plate 341, and when the transmission rod 34 rotates, the qualified position point marking unit 51, the unqualified position point marking unit 52 and the pressure loading unit 42 are alternately located below the first lifting rod 41.

[0039] See also Figure 5 and Figure 6 In some possible embodiments, the second driving member 35 includes a driving motor and a transmission wheel set that is transmission-connected between the driving motor and the transmission rod 34 .

[0040] See also Figure 5 and Figure 6 In some possible embodiments, the qualified position point marking unit 51 and the unqualified position point marking unit 52 can be a marking machine, an ink spray gun, a labeling machine, a stamping machine, etc., which can leave marks on the surface of the prefabricated component. The specific settings can be selected according to actual needs.

[0041] Optionally, the qualified position point marking unit 51 and the unqualified position point marking unit 52 may be driven by the first lifting rod 41 or by a built-in driving unit when working.

[0042] When multiple prefabricated components are inspected at the same time, or multiple positions of a single prefabricated component are inspected, after each inspection, if the deformation of the prefabricated component is qualified, a qualified mark can be marked on the position point through the marking component 50. If the deformation of the prefabricated component is unqualified, an unqualified mark can be marked on the position point through the marking component 50 to facilitate subsequent inspection by the inspector.

[0043] In some possible embodiments, when marking is performed by labeling or spraying ink, in order to prevent dust on the surface of the prefabricated component from affecting the use effect of the ink spray gun or labeling machine, the marking component 50 also includes a cleaning spray gun, which is arranged at the corresponding qualified position point marking unit 51 and the unqualified position point marking unit 52. The air inlet end of the cleaning spray gun is connected to the air source, and the air outlet end of the cleaning spray gun is facing the detection position of the prefabricated component. Before the marking component 50 works, the surface of the prefabricated component can be purged to blow away the dust, thereby ensuring that the ink or sticker is smoothly affixed to the prefabricated component.

[0044] See also Figure 3 and Figure 5 In some possible embodiments, the prefabricated component strength detection device further includes a verticality detection assembly 60, and the verticality detection assembly 60 is arranged at intervals along the circumference of the mounting plate 341 along with the qualified position point marking unit 51, the unqualified position point marking unit 52 and the pressure loading unit 42. The verticality detection assembly 60 is used to detect whether the surface to be tested is perpendicular to the first lifting rod 41.

[0045] See also Figure 3 and Figure 5 In some possible embodiments, the verticality detection assembly 60 includes a second connecting plate 61, a plurality of detection rods 62, a plurality of third springs 63 and a plurality of second distance measuring sensors 64. The second connecting plate 61 is arranged on the mounting plate 341; a plurality of detection rods 62 are respectively arranged on the second connecting plate 61, the detection rods 62 are slidably matched with the second connecting plate 61, and can move up and down in the vertical direction, the lower end of the detection rod 62 is used to abut against the surface of the prefabricated component, and the upper end of the detection rod 62 passes through the second connecting plate 61; a plurality of third springs 63 correspond to the detection rods 62 one by one, the third springs 63 are arranged between the lower end of the detection rod 62 and the second connecting plate 61, and the third springs 63 are configured with a preload force to move the detection rod 62 downward; a plurality of second distance measuring sensors 64 correspond to the detection rods 62 one by one, and the second distance measuring sensors 64 are arranged on the second connecting plate 61, and are used to detect the moving distance of the corresponding detection rods 62.

[0046] Before testing the prefabricated component, the transmission rod 34 rotates to make the verticality detection assembly 60 reach the top of the point to be tested. Each detection rod 62 is provided with a second distance sensor 64, which is used to test the displacement of the detection rod 62. By analyzing and judging the values ​​of multiple second distance sensors 64, it can be known whether the transmission rod 34 is perpendicular to the surface of the prefabricated component at this time.

[0047] Optionally, the verticality detection assembly 60 has the following two driving modes, and the user can select and set them according to the situation. Mode 1: driven by the transmission rod 34, the transmission rod 34 descends, so that the detection rod 62 abuts against the surface of the prefabricated component. Mode 2: driven by the first lifting rod 41, the first lifting rod 41 descends, pushing the second connecting plate 61 to move downward, so that the detection rod 62 abuts against the surface of the prefabricated component.
