Description

Technical Field

[0002] Steel structure is a technology that uses steel as the main structural material for construction or engineering. Steel structure has the advantages of light weight, high strength, good plasticity, and fast construction speed. It is widely used in bridges, buildings, petrochemical equipment, power equipment and other fields.

[0003] During use, steel structures may face various mechanical and environmental influences, such as load, vibration, corrosion, etc. These factors may cause defects or damage to the steel structure, thereby affecting its structural strength and stability. At present, in order to detect and evaluate the defects and damage of steel structures and take timely repair or reinforcement measures, ultrasonic detection devices are usually used for detection, which use the propagation and reflection characteristics of ultrasonic waves to detect the interior of the steel structure. However, the currently installed steel structures are usually laid at high places, so when inspecting the steel structures, it is necessary to complete the inspection work with the assistance of scaffolding or hoists, and high-altitude operations will increase the difficulty of inspection and increase the workload. Moreover, scaffolding and hoists cannot be set up in places where some steel structures are densely intertwined, making it difficult to open inspection operations, so they need to be improved and optimized.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 6 As shown, the utility model provides a nondestructive testing device for steel structure engineering quality, including a data receiver 1, the data receiver 1 is fixedly connected to a storage bin 2, the data receiver 1 is fixedly connected to a connecting line 3, one end of the connecting line 3 passes through the storage bin 2 and is fixedly connected to a fixed shell 4, and one end of the fixed shell 4 is fixedly provided with an ultrasonic probe 5;

[0032] A connecting mechanism, fixedly mounted on one end of the fixed shell 4;

[0033] The extension mechanism is rotatably connected to the connecting mechanism;

[0035] When it is necessary to inspect the steel structure, the staff first places the fixed shell 4 on the surface of the steel structure so that the ultrasonic probe 5 can inspect it, and then turns the knob 13. The rotation of the knob 13 drives the gear 2 12 to rotate, and through the transmission of the connecting rod 14, the two sets of gears 10 are rotated. The rotation of the gear 10 drives the two sets of threaded rods 17 to rotate. Since the threaded rod 17 and the clamping plate 8 are threadedly sleeved, the two sets of clamping plates 8 clamp the steel structure inward. At this time, the roller 9 and the outer wall of the steel structure conflict with each other. The staff can move the fixed shell 4 through the roller 9. When inspecting the high steel structure, the staff cannot move the ultrasonic probe 5 to a distant position to be inspected. At this time, the staff can hold the extension arm 20 tightly and pull the connecting arm 17, the connecting head 18 and the extension arm 20, to rotate it to adjust the position of the ultrasonic probe 5. At this time, the damping shaft 16 can fix the positions of the connecting arm 17, the connecting head 18 and the extension arm 20. Then the staff turns the knob 21 to rotate the threaded rod 22. The rotation of the threaded rod 22 drives the extension arm 19 to move outside the extension arm 20, further extending the detection position of the ultrasonic probe 5. At this time, the staff can freely control the detection location of the ultrasonic probe 5 by holding the extension arm 20. When the detection is completed, the staff reverses the knob 21 to retract the ultrasonic probe 5, and reverses the knob 13 to complete the disassembly. Finally, the staff rotates the knob 3 24 to rotate the storage roller 23, further winding the connecting line 3 around the outer wall of the storage roller 23 to store the connecting line 3.

[0036] By rotating knob 13, the two groups of clamps 8 are fixed inward to fix the steel structure, and at this time the ultrasonic probe 5 can detect the steel structure, and then by rotating knob 21, the extension arm 19 is moved outward of the extension arm 20, further extending the detection position of the ultrasonic probe 5. Compared with the traditional device, the device enables the ultrasonic probe 5 to be movably installed on the surface of the steel structure and detect the steel structure through the setting of the fixing mechanism, and then through the setting of the extension mechanism, the detection range of the ultrasonic probe 5 is increased, thereby avoiding the occurrence of detection blind spots and reducing the workload.

[0040] Compared with the traditional device, the device allows the connecting wire 3 to be wound around the outer wall of the storage roller 23 by rotating the knob three 24. Compared with the traditional device, the device can store the connecting wire 3 through the storage mechanism, avoiding the mutual entanglement and knotting of the connecting wire 3, effectively preventing the connecting wire 3 from being damaged, and improving the service life of the device.

The upper gear 12 is fixedly connected to a knob 13, and the knob 13 is rotatably installed on the top of the fixed groove 11.

[0042] The staff first places the fixed shell 4 on the surface of the steel structure so that the ultrasonic probe 5 can detect it, and then turns the knob 13. The rotation of the knob 13 drives the gear 2 12 to rotate, and through the transmission of the connecting rod 14, the two sets of gears 10 rotate to provide power.

[0046] The staff turns knob 21 to rotate threaded rod 22.

[0049] The working principle and use process of this utility model:

[0050] When it is necessary to inspect the steel structure, the staff first places the fixed shell 4 on the surface of the steel structure so that the ultrasonic probe 5 can inspect it, and then turns the knob 13. The rotation of the knob 13 drives the gear 2 12 to rotate, and through the transmission of the connecting rod 14, the two sets of gears 10 are rotated. The rotation of the gear 10 drives the two sets of threaded rods 17 to rotate. Since the threaded rod 17 and the clamping plate 8 are threadedly sleeved, the two sets of clamping plates 8 clamp the steel structure inward. At this time, the roller 9 and the outer wall of the steel structure conflict with each other. The staff can move the fixed shell 4 through the roller 9. When inspecting the high steel structure, the staff cannot move the ultrasonic probe 5 to a distant position to be inspected. At this time, the staff can hold the extension arm 20 tightly and pull the connecting arm 17, the connecting head 18 and the extension arm 20, to rotate it to adjust the position of the ultrasonic probe 5. At this time, the damping shaft 16 can fix the positions of the connecting arm 17, the connecting head 18 and the extension arm 20. Then the staff turns the knob 21 to rotate the threaded rod 22. The rotation of the threaded rod 22 drives the extension arm 19 to move outside the extension arm 20, further extending the detection position of the ultrasonic probe 5. At this time, the staff can freely control the detection location of the ultrasonic probe 5 by holding the extension arm 20. When the detection is completed, the staff reverses the knob 21 to retract the ultrasonic probe 5, and reverses the knob 13 to complete the disassembly. Finally, the staff rotates the knob 3 24 to rotate the storage roller 23, further winding the connecting line 3 around the outer wall of the storage roller 23 to store the connecting line 3.
