[0054] A detection method for a zero-value error calibration structure used in a building engineering quality detector, the specific steps of which are as follows:

[0055] S1. When the first counterweight detection block 11 in the first detection adjustment unit 3 and the second detection adjustment unit 4 are both slid to the end of the sliding adjustment plate 13 facing the detection limit frame 1 and no second counterweight block 27 and auxiliary counterweight block 28 are added, the detection platform 9 is in a horizontal state, and at this time the indicator plate 8 indicates the "0" scale line in the dial 6.

[0056] S2, according to the weight of the building materials to be detected, the first counterweight detection block 11 is slid along the sliding adjusting plate 13 by rotating the first fastening threaded column 12 to a specified distance, and a specified number of second counterweight blocks 27 are placed outside the limiting frame 26, the second hydraulic cylinder 32 is started to make the sliding adjusting plate 31 slide outward along the limiting frame 26, so that the supporting plate 29 is inserted into the second counterweight block 27, so that the second counterweight block 27 is hooked on the limiting frame 26, thereby adding weight to the inside of the first detection adjusting part 3 and the second detection adjusting part 4;

[0057] S3, after the second counterweight block 27 with the same weight as the material to be checked and the first counterweight detection block 11 are slid along the sliding adjusting plate 13 to a specified distance, the material to be detected is placed inside the detection limiting frame 1, and the rotating roller 2 rotating at the bottom of the detection limiting frame 1 can quickly and conveniently place the material to be detected inside the detection limiting frame 1;

[0058] S4, the supporting hydraulic cylinder 5 is started to make the upper end of the supporting hydraulic cylinder 5 no longer support the bottom of the detection platform 9, at this time the horizontal state of the detection platform 9 indicates that the weight of the material to be detected is the same as the expected value, when the detection platform 9 tilts towards one end of the detection limiting frame 1, it indicates that the weight of the material to be detected is overweight, when the detection platform 9 tilts towards one end of the first detection adjusting part 3 and the second detection adjusting part 4, it indicates that the weight of the material to be detected is light, and during the detection process, the detection result can be observed by observing the change of the value on the scale 6 indicated by the indicating plate 8;

[0059] S5, the double-head motor 19 is started to drive the driving rod 21 and the synchronous rotating wheel 20 to rotate, which can make the synchronous rotating adjusting belt 22 and the counterweight adjusting device 23 arranged at the bottom of the synchronous rotating adjusting belt 22 move horizontally, and the auxiliary counterweight block 28 can be screw-fixedly connected to the bottom of the second counterweight block 27 through the threaded connecting column 30, so as to adjust and control the detection accuracy and the detection range of the device.

[0060] The working principle is that when the first counterweight detection block 11 in the first detection adjusting part 3 and the second detection adjusting part 4 is slid to the end of the detection limiting frame 1 and no second counterweight block 27 and auxiliary counterweight block 28 are added, the detection table plate 9 is in a horizontal state, and at this time the indicating plate 8 indicates the "0" scale line in the scale disc 6.

After the second counterweight block 27 equivalent to the weight of the material to be checked and the first counterweight detection block 11 are slid along the sliding adjusting plate 13 by a specified distance, the material to be detected is placed in the inside of the detection limiting frame 1. The material to be detected can be quickly and conveniently placed in the inside of the detection limiting frame 1 by the rotating roller 2 rotating at the bottom of the detection limiting frame 1. The supporting hydraulic cylinder 5 is started to make the upper end of the supporting hydraulic cylinder 5 no longer support the bottom of the detection table plate 9. At this time, the horizontal state of the detection table plate 9 indicates that the weight of the material to be detected is the same as the expected value. When the detection table plate 9 tilts towards one end of the detection limiting frame 1, it indicates that the weight of the material to be detected is overweight. When the detection table plate 9 tilts towards one end where the first detection adjusting part 3 and the second detection adjusting part 4 are installed, it indicates that the weight of the material to be detected is light. During the detection process, the detection result can be observed by observing the numerical value change indicated on the scale disc 6 by the indicating plate 8. The double-head motor 19 is started to drive the driving rod 21 and the synchronous rotating wheel 20 to rotate, so that the synchronous rotating adjusting belt 22 and the counterweight adjusting device 23 arranged at the bottom of the synchronous rotating adjusting belt 22 can move horizontally. The auxiliary counterweight block 28 can be screw-fixedly connected to the bottom of the second counterweight block 27 through the threaded connecting column 30, so that the detection accuracy and the detection range of the device can be adjusted and controlled. The first counterweight detection block 11 can be accurately controlled and adjusted to slide along the sliding adjusting plate 13 by observing the second moving scale line 33. The device can conveniently add the building material to be detected into the inside of the detection limiting frame 1 by arranging the rotating roller 2 in the inside of the bottom end of the detection limiting frame 1. The first detection adjusting part 3 and the second detection adjusting part 4 can adjust and control one end of the detection table plate 9 by different weights through the first detection adjusting part 3 and the second detection adjusting part 4, so that the device can quickly detect materials of different weights. The first counterweight detection block 11 slides along the sliding adjusting plate 13, and the bottom of the synchronous rotating adjusting belt 22 adjusts different numbers of first fastening threaded columns 12.And the second weight block 27 can be added in the counterweight adjusting device 23 conveniently and quickly, so that the detection accuracy and the detection range of the device can be adjusted and controlled conveniently and quickly. The mass of the second weight block 27 is 5 kg, the mass of the auxiliary weight block 28 is 1 kg, and the mass of the first weight detection block 11 is 10 kg.

7. The detection method for a zero-value error calibration structure for a building engineering quality detector according to claim 6, characterized in that, The specific steps of this method are as follows: S1. When the first counterweight detection block (11) in the first detection adjustment unit (3) and the second detection adjustment unit (4) are both slid to the end of the sliding adjustment plate (13) facing the detection limit frame (1) and no second counterweight block (27) and auxiliary counterweight block (28) are added, the detection platform (9) is in a horizontal state, and at this time the indicator plate (8) indicates the "0" scale line in the dial (6); S2. Based on the weight of the building materials to be tested, the first counterweight detection block (11) is slid along the sliding adjustment plate (13) a specified distance by tightening the first fastening threaded column (12), and a specified number of second counterweight blocks (27) are placed outside the limiting frame (26). The second hydraulic cylinder (32) is activated to make the sliding adjustment plate (31) slide outward along the limiting frame (26), so that the support plate (29) is inserted into the interior of the second counterweight block (27), so that the second counterweight block (27) is hooked on the limiting frame (26), thereby adding weight to the interior of the first detection adjustment part (3) and the second detection adjustment part (4). S3. After sliding the second counterweight (27) of the same weight as the material to be inspected and the first counterweight detection block (11) along the sliding adjustment plate (13) for a specified distance, the material to be inspected is placed inside the detection limit frame (1). The material to be inspected can be placed inside the detection limit frame (1) quickly and conveniently by rotating the rotating roller (2) at the bottom of the detection limit frame (1). S4. Start the support hydraulic cylinder (5) so that the upper end of the support hydraulic cylinder (5) no longer supports the bottom of the test platform (9). At this time, the test platform (9) is in a horizontal state, indicating that the weight of the material being tested is the same as the expected value. When the test platform (9) tilts towards the end of the test limit frame (1), it indicates that the weight of the material being tested is too heavy. When the test platform (9) tilts towards the end where the first test adjustment part (3) and the second test adjustment part (4) are installed, it indicates that the weight of the material being tested is light. During the test, the test results can be easily observed by observing the change in the value indicated on the dial (6) by the indicator plate (8). S5. Start the dual-head motor (19) to drive the drive rod (21) and the synchronous rotating wheel (20) to rotate, so that the synchronous rotating adjustment belt (22) and the counterweight adjustment device (23) set at the bottom of the synchronous rotating adjustment belt (22) can move laterally. And through the threaded connecting column (30), the auxiliary counterweight block (28) can be threadedly fixed to the bottom of the second counterweight block (27), so that the detection accuracy and detection range of this device can be adjusted and controlled.
