Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a non-destructive detection device for the quality of welds in steel structure engineering. Background Art

[0002] Steel structure is an important structural type widely used in construction projects, and its welding parts are the key parts connecting different components. To ensure the safety and stability of steel structures, strict quality control of welds must be carried out. Among them, non-destructive testing is a detection method that crosses disciplines and is used in an integrated manner. It has become an important means of modern welding quality control. However, the current non-destructive testing device uses handheld detectors to detect welds. When encountering materials such as square steel, after inspecting three sides, the fourth side needs to be manually turned out. The weld quality cannot be inspected at one time, which increases time costs.

[0003] Therefore, a non-destructive testing device for the quality of welds in steel structure engineering is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcoming in the prior art that the quality of the weld cannot be fully detected at one time, and to propose a non-destructive testing device for the quality of the weld in steel structure engineering.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A nondestructive testing device for the quality of welds in steel structure engineering, comprising a base plate, a U-shaped plate fixedly mounted on the surface of the base plate, large gears rotatably mounted on both sides of the U-shaped plate, a first positioning plate and a second positioning plate fixedly mounted on the sides of the two large gears close to each other, a fixed block fixedly mounted on one side of the first positioning plate, a first clamping plate fixedly mounted on one side of the fixed block, a third electric push rod fixedly mounted on one side of the second positioning plate, a second clamping plate fixedly mounted on the telescopic end of the third electric push rod, and a groove provided on the surface of the base plate;

[0007] Detection component, used to detect the quality of the weld of the material being tested;

[0008] Transmission assembly, used to drive the large gear to rotate.

[0009] In one possible design, the detection component includes a screw rod rotatably mounted on the upper end of a U-shaped plate, the circumferential thread of the screw rod is connected to a slider, a second electric push rod is fixedly mounted on the bottom of the slider, a mounting box is fixedly mounted on the telescopic end of the second electric push rod, an ultrasonic detector is mounted in the mounting box, and an ultrasonic detection head is mounted on the bottom of the mounting box, and the ultrasonic detection head is electrically connected to the ultrasonic detector.

[0010] In a possible design, the transmission assembly includes a rotating rod rotatably mounted in the groove, and small gears are fixedly mounted on both ends of the rotating rod, and the small gears are meshed with the large gear.

[0011] In one possible design, a first motor and a second motor are fixedly mounted on the same side of the base plate and the U-shaped plate, respectively. The output shaft of the first motor passes through the base plate and is fixedly connected to the rotating rod, and the output shaft of the second motor passes through the U-shaped plate and is fixedly connected to the screw rod.

[0012] In a possible design, a support plate is fixedly mounted on the inner wall of the groove, first electric push rods are fixedly mounted on both sides of the top of the support plate, and the telescopic ends of the two first electric push rods are fixedly mounted with the same placement plate.

[0013] In a possible design, a guide rod is fixedly mounted on the top of the U-shaped plate, and the guide rod is slidably connected to the slider.

[0014] In a possible design, a positioning block is fixedly installed in the groove, and the positioning block is rotatably connected to the rotating rod.

[0015] In this application, the square steel to be inspected is placed on the placement plate, and the first electric push rod pushes the placement plate upward. When the square steel passes through the gap between the first clamping plate and the second clamping plate, the third electric push rod pushes the second clamping plate closer to the first clamping plate. Finally, the first clamping plate and the second clamping plate firmly fix the square steel, and the second motor is started. The second motor drives the screw rod to rotate, and the slider on the circumference of the screw rod slides to move the ultrasonic detector above the detection position. At this time, the second electric push rod pushes the installation box downward until the ultrasonic detection head contacts the surface of the square steel and performs detection. When one side is detected, the first motor is started, and the first motor drives the rotating rod and the small gears at both ends to rotate. At the same time, the small gear engages with the large gear, driving the large gear to rotate, so that the clamped square steel is rotated to the other side, and this is repeated until all the welds on the four sides of the square steel are inspected. No manual flipping is required and the inspection can be completed in one go.

[0016] Beneficial effects:

[0017] In the utility model, a nondestructive testing device for the quality of welds in steel structure engineering is described. The third electric push rod pushes the second clamping plate toward the first clamping plate to clamp the square steel. The small gear is engaged with the large gear to rotate the square steel clamped by the first and second clamping plates, so that the ultrasonic detector can detect four surfaces at one time without manual flipping.

[0018] In the utility model, a nondestructive testing device for the quality of welds in steel structure engineering is described. The second motor drives the screw to rotate, and the slider on the circumference of the screw drives the installation box and the ultrasonic detector inside it to move, so that welds at different positions of the square steel can be tested.
