Description

Technical Field

[0001] This utility model relates to the field of steel pipe testing technology, specifically to a device for testing the wall thickness of a building enclosed cavity steel pipe. Background Technology

[0002] With the development of my country's cities, the number of light industrial plants, stadiums, entertainment venues, public buildings, warehouses and storage facilities, exhibition halls, and supermarkets has been increasing year by year. Correspondingly, the number of buildings with various roofing systems is also increasing. These buildings typically use large-span steel structure light steel roofs. Common structural forms for light steel plants include portal frame structures, space frame structures, tubular truss structures, frame structures, and simple angle steel roof truss structures. As these structures age or new roof loads are added, structural safety assessments of these space frame structures are necessary. Structural safety assessments require the original design data of the structure. If the design data is missing, it poses a significant challenge to the testing and assessment of space frame or frame structures, especially since most of these structures consist of closed-cavity steel pipe components. Measuring the wall thickness of the steel pipes is crucial data for structural safety assessment. Currently, acoustic or electromagnetic testing instruments for measuring the wall thickness of closed-cavity steel pipes suffer from large dimensional deviations or even distortions due to interference from numerous existing structural components on-site. To meet the technical requirements for detecting the wall thickness of enclosed hollow steel pipes, it is urgent to develop a wall thickness detection device for enclosed hollow steel pipes in buildings. This device should be easy to operate, cause minimal damage to the original structure, and not affect the load-bearing performance of structural components after minimally invasive sealing.

[0027] The working principle of this utility model is as follows: A steel pipe is placed on a fixed plate 602, and then a positioning plate 601 is placed on the steel pipe. One end of the positioning plate 601 is fixed to the fixed plate 602 by locking screws 605 and locking nuts 606, and the other end of the positioning plate 601 is fixed to the fixed plate 602 by positioning screws 608 and positioning nuts 609. Thus, the steel pipe is fixed between the positioning plate 601 and the fixed plate 602. After the steel pipe is fixed, the drive motor 202 drives the lead screw 206 to rotate. The lead screw 206 drives the lead screw nut and nut seat 205 to move, and the moving plate 201 also moves accordingly, thereby driving the drilling machine. Mechanism 4 moves to below the steel pipe. First cylinder 407 pushes first lifting plate 403 upwards, and motor 402 and drill bit 401 also move upwards. Motor 402 drives drill bit 401 to rotate. The rotating drill bit 401 drills through the second oblong hole 610 into the steel pipe. After the steel pipe wall is pierced, motor 402 stops working. First cylinder 407 drives first lifting plate 403, motor 402, and drill bit 401 downwards to reset. Drive motor 202 drives measuring mechanism 5 to move to below the steel pipe. Second cylinder 506 pushes second lifting plate 502 upwards, and probe 501 also moves upwards. The needle 501 extends into the steel pipe through the second oblong hole 610 and the through hole, so that the top of the needle 501 abuts against the inner wall of the steel pipe. At this time, the pressure sensor senses the pressure value and sends the pressure value to the controller. The controller controls the second cylinder 506 to stop working. By reading the scale value D1 on the needle at the second oblong hole 610, after the measurement is completed, the second cylinder 506 drives the needle 501 to move downward to reset. The drive motor 202 drives the measuring mechanism 5 to move below the third oblong hole 611. The second cylinder 506 pushes the second lifting plate 502 upward, and the needle 501 also moves upward. The needle 501 extends into the positioning plate 601 through the third oblong hole 611, so that the top of the needle 501 abuts against the bottom of the positioning plate 601. At this time, the pressure sensor senses the pressure value and sends the pressure value to the controller. The controller controls the second cylinder 506 to stop working. By reading the scale value D2 on the needle 501 at the third oblong hole 611, the thickness value D of the steel pipe can be calculated according to the formula D = D2 - D1, thereby realizing the wall thickness measurement of the closed cavity steel pipe. After the measurement is completed, the steel pipe is taken out, and a stud is inserted into the drilled hole of the steel pipe. Then, the stud is locally ground, and after the grinding is completed, paint is applied to the stud.
