Description

Technical Field

[0001] The present invention relates to the technical field of the strength detection of construction steel, and particularly to a construction engineering construction detection device and a using method thereof. Background Art

[0002] During the construction process of construction projects, a large amount of steel is usually required for high-strength support. In order to improve the safety of construction projects, it is necessary to conduct sampling inspections on this steel, especially strength inspections. Using a construction engineering construction detection device is a conventional method at present. However, the existing construction engineering construction detection devices have the following problems when in use: Regarding the strength detection of steel, most of the existing technologies use a press to apply pressure to the steel to detect its compressive capacity. However, the existing construction engineering construction detection devices are not convenient for detecting the compressive situation of steel in real time and conveniently. After the steel is pressed, damage is likely to occur both externally and internally, and the internal damage cannot be observed with the naked eye, requiring additional use of flaw detection equipment, resulting in a more cumbersome detection process. At the same time, there are many types and specifications of steel in construction. The existing construction engineering construction detection devices are not convenient for detecting steel of different specifications. For steel of different specifications, the maximum bending degree is different, and the press needs to adjust the pressurization range of different degrees, which involves the installation position, installation height, operation process and program design of the workpiece, and is relatively cumbersome, making it difficult to achieve an ideal effect.

[0003] In view of the above problems, there is an urgent need to innovate and design on the basis of the original construction engineering construction detection device. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the workpiece is placed and bent under pressure, the bottom is always in contact with the bottom plate, and the bottom plate cooperates with the second elastic telescopic rod to follow the workpiece. Whether the workpiece is deformed during pressure bending and resetting can be determined by the position of the bottom plate after resetting, and the pressure bearing capacity and strength of the workpiece can be determined by the damage to the workpiece. With the naked eye observation of the external cracks of the workpiece, the detection result can be directly or detected without the need to use machine flaw detection equipment and other equipment for detection again. The detection process is relatively simple and practical, which greatly improves the detection efficiency. Furthermore, the movement of the bottom plate and the second elastic telescopic rod can drive the two bases to move inward through the contraction component, thereby reducing the friction area on both sides of the workpiece after bending. At the same time, the resistance block can be forced to move upward to reserve space for the warping of the two ends of the workpiece, which can effectively protect the workpiece and avoid damage to the qualified workpiece during the detection process. 2. The present invention can be applied to workpieces with different widths, lengths and thicknesses. The two ends of the workpiece are positioned by the movement of the positioning bar. Since the maximum downward pressing arc changes after the workpieces with different lengths are pressed and bent, the movement of the positioning bar can drive the vertical movement of the base, that is, the longer the workpiece, the higher the height of the base, and the earlier the pressure mechanism moves down to contact. Therefore, the pressure mechanism on the intelligent control box only needs to output a constant stroke to meet the pressure detection requirements of workpieces with different lengths. Further, for workpieces with different thicknesses, during installation, the height of the connecting seat can be adjusted again through the abutting block cooperating with the second piston rod. The thicker the workpiece, the greater the change in the maximum downward pressing arc after being pressed and bent. That is, the thicker the workpiece, the smaller the downward pressing arc and the lower the height of the connecting seat. The pressure mechanism on the intelligent control box only needs to output a constant stroke to meet the pressure detection requirements of workpieces with different thicknesses. On this basis, this device can conveniently detect different types of workpieces without complex program design and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment Four Based on Embodiment Three, please refer to Figures 1-5 , the method includes the following steps: S1: According to the width of the workpiece to be detected, rotate the knob 61 to adjust the distance between the two positioning seats 7, and according to the length of the workpiece to be detected, drive the second screw rod 171 to rotate through the motor to adjust the distance between the two positioning bars 172; S2: When adjusting the length, adjust the height of the mounting bracket 2 through the third screw rod 173, thereby adjusting the initial heights of the connecting seat 6 and the positioning seat 7, and adjusting the initial height of the bottom plate 19; S3: Place both ends of the workpiece on the connecting seat 6 between the two positioning seats 7, and then start the electric push rod 9 to push the positioning frame 8 towards the workpiece.

[0024] Working principle: When using this construction project construction detection device, first, according to the length of the workpiece to be measured, the second screw rod 171 is driven to rotate by the motor. The second screw rod 171 drives the two positioning bars 172 to move towards each other, and the two ends of the workpiece are positioned by the two positioning bars 172. The second screw rod 171 drives the mounting frame 2 to move vertically through the third screw rod 173, and then drives the connecting seat 6 and the positioning seat 7 to adjust their positions through the mounting rod 3, the base 4, and the first elastic telescopic rod 5. At the same time, the bottom plate 19 is driven by the second elastic telescopic rod 18 to adjust its initial position. According to the width of the workpiece, the knob 61 is rotated. The knob 61 drives the two connecting rods 63 to move towards each other through the first screw rod 62, and the width between the two positioning seats 7 is adjusted; Place the workpiece on the connecting seat 6 and the positioning seat 7, and position it through the two positioning bars 172. Then, the positioning frame 8 is pushed towards the workpiece by the electric push rod 9. The bottom inclined surface of the contact block 12 contacts the workpiece and moves upward under force, pushing the first piston rod 11 to move upward in the oil tank 10, squeezing the oil into the oil cavity 15, and pushing the second piston rod 14 and the connecting seat 6 to move, so that the initial position of the connecting seat 6 is again suitable for workpieces of different thicknesses. During the detection, the electromagnet 16 is energized to fix the position of the second piston rod 14 to prevent it from moving again when pressed. Through the constant stroke output by the pressure mechanism on the intelligent control box 101, the workpiece is squeezed, bent, and reset. During this process, the solenoid valve in the pipeline between the oil tank 10 and the transfer cavity 13 is opened. When the workpiece is bent, both ends of the workpiece are lifted, and the contact block 12 has room for movement and will not damage the workpiece. When the workpiece is bent and reset, the bottom contacts the bottom plate 19, driving it to move downward and reset. Through the induction of the distance of the bottom plate 19 after moving and resetting by the laser distance sensor 20, the deformation of the workpiece after being bent and reset under force is determined, and the workpiece is detected in real time. Further, the bottom plate 19 drives the telescopic movement of the second elastic telescopic rod 18, so that the vertical bar 214 enters the contraction groove 213, driving the horizontal bar 212 to move inward, and then driving the two bases 4 to move inward, which conforms to the deformation range after the workpiece is bent, reduces workpiece wear, and protects the workpiece.
