[0002] Many building structures have beam-column structures (such as ground ring beams, columns, house beams, etc.). The width of the beams and columns is an important criterion for judging whether their quality meets the requirements. During cast-in-place construction, the width of the beams and columns may exceed the limit or be too small due to problems with formwork installation or deformation. Therefore, it is usually necessary to test the width of these beams and columns during engineering inspections.

[0003] In the prior art, for the width detection of beams and columns, some methods are to select several measuring points along the axial direction of the beams and columns, and use tools such as rulers to measure the width at the measuring points. If the width of the beams and columns measured at each measuring point is within the specified range, it can be judged that the width of the beams and columns meets the requirements. However, in some cases, the width of the beams and columns at certain positions between the measuring points may not be within the specified range. Since these positions are not detected, it is easy for the beams and columns to be mistakenly detected as qualified, resulting in low accuracy in the width detection of the beams and columns.

[0024] Reference Figure 1-5A mobile concrete beam-column detection device comprises a vehicle body 10, a stop mechanism 20 and a detection mechanism 30, wherein a first walking wheel 11 is arranged at the bottom of the vehicle body 10, and a mounting frame 40 is arranged at the rear side of the vehicle body 10, the stop mechanism 20 comprises a first guide rod 21, a first stop plate 22, a second guide rod 23, a second stop plate 24 and a tension spring 25, one end of the first guide rod 21 is inserted into one side of the mounting frame 40, the other end of the first guide rod 21 is connected to the first stop plate 22, one end of the second guide rod 23 is inserted into the other side of the mounting frame 40, the other end of the second guide rod 23 is connected to the second stop plate 24, and second walking wheels 26 are arranged on opposite sides of the first stop plate 22 and the second stop plate 24, the first guide rod 21 and the second guide rod 23 are both sleeved with tension springs 25, one end of the two tension springs 25 is respectively connected to the first stop plate 22 and the second stop plate 24, and the other ends of the two tension springs 25 are connected to the mounting frame 40. The detection mechanism 30 includes a measuring rod 31, a measuring cylinder 32, a detection frame 33 and a detection switch 34. The measuring rod 31, the first guide rod 21 and the second guide rod 23 are all arranged transversely. One end of the measuring rod 31 is connected to the first stop plate 22. The measuring cylinder 32 is sleeved on the measuring rod 31, and a shift bar 321 is provided on the outer side wall of the measuring cylinder 32. The detection frame 33 is provided on the second stop plate 24. Two detection switches 34 are provided and arranged at intervals along the axial direction of the measuring rod 31. Both detection switches 34 are provided on the detection frame 33, and the two detection switches 34 are provided on both sides of the shift bar 321. When the shift bar 321 moves close to / abuts against the detection switch 34, the detection switch 34 can be triggered.

[0025] The detection switch 34 can be configured as a proximity switch, a limit switch, or the like. The two detection switches 34 are each electrically connected to an alarm component, and the two alarm components can emit different alarm signals to prompt the detection personnel to move the dial bar 321 to trigger the corresponding detection switch 34. For example, the two alarm components can be alarm lights with different luminous colors; or, one of the alarm components is an alarm light, and the other alarm component is a buzzer.

[0026] During operation, the vehicle body 10 is placed on the beam column, and the first stop plate 22 and the second stop plate 24 are arranged on both sides of the beam column. The first running wheel 11 and the second running wheel 26 are both in contact with the surface of the beam column, pushing the vehicle body 10 to move along the surface of the beam column. As the width of the beam column changes, the distance between the first stop plate 22 and the second stop plate 24 will change, and the lever 321 will also move relative to the detection frame 33: if the width of the beam column meets the requirements, the lever 321 is located between the two detection switches 34, and the two detection switches 34 will not be triggered; if the width of the beam column is too large or too small and does not meet the design requirements, the lever 321 will move relative to the detection frame 33 to trigger the corresponding detection switch 34, and the corresponding alarm component electrically connected to the detection switch 34 will send out an alarm signal. When the alarm signal is sent out, the inspection personnel stop moving the vehicle body 10 and mark the beam column so that the beam column can be further evaluated in detail later and the accurate width value at that location can be measured, thereby providing a reference for repairing or removing the beam column.

[0027] As in the above-mentioned structure, when performing inspection, by abutting the first running wheel 11 and the second running wheel 26 against the surface of the beam and column, the vehicle body 10 is pushed to move along the surface of the beam and column, so that the inspection mechanism 30 can continuously inspect the width of the beam and column. Compared with the point selection measurement method, the continuous inspection adopted in this scheme can avoid the situation where the position where the width of the beam and column is not within the prescribed range is not inspected, thereby improving the accuracy of the measurement of the width of the beam and column; through the cooperation of the dial bar 321 and the detection switch 34 in the detection mechanism 20, an alarm can be issued in time when the width of the beam and column is too large or too small and does not meet the design requirements, so that the inspection personnel can find the position where the width of the beam and column is unqualified in time.

[0028] In this embodiment, a guide plate 50 is provided at the rear side of the mounting frame 40, and the measuring rod 31 is slidably arranged on the guide plate 50. The guide plate 50 can support and guide the measuring rod 31 to prevent it from sagging and moving in a biased direction.

[0029] In this embodiment, the measuring cylinder 32 is movably sleeved on the measuring rod 31 and can rotate and slide relative to the measuring rod 31. The side wall of the measuring cylinder 32 is threaded and inserted into the positioning bolt 35. The end of the positioning bolt 35 stops against the measuring rod 31. The measuring rod 31 is provided with a scale. Through this structure, according to the qualified width value of the beam column to be measured, the measuring cylinder 32 is slid along the measuring rod 31 to adjust the position, so as to ensure that when different beam columns are detected, the shift bar 321 can be located between the two detection switches 34. In this way, the utility model can be adapted to the measurement of beam columns of different widths, and the adaptability range is improved. Among them, the position of the measuring cylinder 32 can be clearly understood according to the scale on the measuring rod 31, so as to facilitate adjustment.

[0030] In addition, since the measuring cylinder 32 can rotate relative to the measuring rod 31, before performing the detection, the measuring cylinder 32 can be rotated to make the shift bar 321 leave between the two detection switches 34 to avoid contact and collision between the shift bar 321 and the detection switch 34. After sliding and adjusting the position of the measuring cylinder 32 and placing the two sets of second walking wheels 26 between the beams to be measured, the measuring cylinder 32 is rotated to make the shift bar 321 located between the two detection switches 34.

[0031] Furthermore, a limiting groove 311 is provided on the side wall of the measuring rod 31, the limiting groove 311 is parallel to the axis of the measuring rod 31, and the cross section of the limiting groove 311 is arc-shaped, and the positioning bolt 35 extends to be inserted into the limiting groove 311. The rotation angle of the measuring cylinder 32 can be controlled by the limiting groove 311 to ensure that the shifting bar 321 is located in the correct position: when the side wall of the positioning bolt 35 stops against one side wall of the limiting groove 311, the shifting bar 321 is located between the two detection switches 34; when the side wall of the positioning bolt 35 stops against the other side wall of the limiting groove 311, the shifting bar 321 leaves between the two detection switches 34.

[0032] In this embodiment, a groove 241 is formed on the top surface of the second stop plate 24, and the detection frame 33 is located in the groove 241. The detection frame 33 includes a first detection seat 331, a first screw rod 332 and a second detection seat 333. The first detection seat 331 is connected to the side wall of the groove 241, the first screw rod 332 is rotatably disposed on the first detection seat 331, and the end of the first screw rod 332 is connected to the first knob 334. The second detection seat 333 is provided in two, one of which is fixedly disposed on the first detection seat 331, and the other second detection seat 333 is cooperatively sleeved on the first screw rod 332, and the second detection seat 333 is slidably connected to the first detection seat 331, and two detection switches 34 are correspondingly disposed on the opposite sides of the two second detection seats 333. Different building inspection requirements require different ranges of differences between the width of beams and columns and the standard values ​​(i.e., within the qualified range, the variation range of the width of beams and columns is required to be different). Through this structure, the distance between the two second inspection seats 333 can be adjusted to adapt to the variation range requirements of the width of beams and columns.

[0033] In this embodiment, the mounting frame 40 includes a first mounting plate 41, a second mounting plate 42, a second guide rail 43, a mounting seat 44 and a second screw rod 45. The first mounting plate 41 and the second mounting plate 42 are arranged on the front side of the vehicle body 10 and are arranged in an upper and lower manner. The second guide rail 43 is arranged between the first mounting plate 41 and the second mounting plate 42. The mounting seat 44 is slidably arranged on the second guide rail 43. The second screw rod 45 is threadedly arranged on the first mounting plate 41, and the second screw rod 45 is rotatably connected to the mounting seat 44. The aforementioned guide plate 50, the first guide rod 21 and the second guide rod 23 are all arranged on the mounting seat 44. By rotating the second screw rod 45, the mounting seat 44 can be driven to rise and fall, and then the stop mechanism 20 and the detection mechanism 30 can be driven to rise and fall, so as to adjust the height difference between the second running wheel 26 and the first running wheel 11, so as to meet the detection requirements of beams and columns with different thicknesses.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments.
