Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for portable ultrasonic flaw detection equipment, in particular to an auxiliary device for portable ultrasonic flaw detection at the pipe end. Background Technique

[0002] In the process of steel pipe production and use, longitudinal flaw detection of the pipe end of the steel pipe is an important link to ensure the quality and use safety of the steel pipe. Existing methods for longitudinal flaw detection at the pipe end have certain problems and challenges in practical applications.

[0003] In practice, due to problems such as the wafer size of the flaw detection probe and wear and focusing during use, defects within 10 mm from the end face are extremely likely to be missed during pipe end flaw detection. To improve this situation, it is usually required to move out half of the wafer from the pipe end for scanning. However, in the actual flaw detection operation process, relying entirely on manual placement and manipulation of the probe, it is very difficult to ensure that the probe can be stably fixed at the established scanning position, which seriously affects the accuracy and reliability of flaw detection and brings great trouble to the quality inspection of steel pipes. Summary of the Utility Model

It includes a housing, an installation frame is arranged at the top of the housing, an adjustment component is arranged inside the installation frame, an adsorption component is movably covered on the housing, the adsorption component is drivingly connected with the adjustment component, and two groups of fixing components are also arranged on the housing.

[0006] Preferably, a pair of slide rails are arranged on each of the left and right side walls of the housing, movable grooves are symmetrically opened on the front and rear wall bodies of the housing, several extrusion springs are arranged on one inner wall of the housing, the tops of several extrusion springs are simultaneously provided with an extrusion plate, translation blocks are symmetrically arranged on both sides of the extrusion plate, the translation blocks are arranged in the movable grooves, and a slot is opened at the tail of the housing, and the slot is located below the movable groove.

Detailed implementation manners

[0027] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0028] As Figures 1 - 12 shown, a pipe-end hand-held ultrasonic flaw detection auxiliary device proposed by the present utility model includes a housing 1. An mounting bracket 11 is provided at the top of the housing 1. An adjusting assembly 3 is provided inside the mounting bracket 11. An adsorption assembly 4 is movably sleeved on the housing 1. The adsorption assembly 4 is drivingly connected to the adjusting assembly 3. Two groups of fixing assemblies 2 are also provided on the housing 1;

[0029] On the left and right side walls of the casing 1, a pair of sliding rails 10 are respectively arranged. On the front and rear wall bodies of the casing 1, movable slots 15 are symmetrically opened. On one inner wall of the casing 1, several extrusion springs 12 are arranged. At the top of the several extrusion springs 12, an extrusion plate 13 is simultaneously arranged. On both sides of the extrusion plate 13, translation blocks 14 are symmetrically arranged. The translation blocks 14 are arranged in the movable slots 15. An opening 16 is opened at the tail of the casing 1, and the opening 16 is located below the movable slot 15;

[0030] The fixing component 2 includes a first mounting block 20 arranged on one side of the casing 1. A "T"-shaped slot 21 is opened in the first mounting block 20. On the side of the casing 1 far from the first mounting block 20, second mounting blocks 22 are symmetrically arranged. A slot 23 is opened in the second mounting blocks 22. Several bolts 26 are threadedly arranged on the second mounting blocks 22. A detachable strap 24 is arranged between the first mounting block 20 and the second mounting blocks 22. One end of the strap 24 is provided with a "T"-shaped block 25. The "T"-shaped block 25 is inserted into the "T"-shaped slot 21. The other end of the strap 24 is inserted into the slot 23, and several bolts 26 abut against the strap 24;

[0031] The adjusting component 3 includes a screw rod 30. The screw rod 30 is movably arranged in the mounting frame 11 through a pair of bearing seats 31. The two bearing seats 31 are respectively arranged on the top and the inner bottom surface of the mounting frame 11. A turning handle 32 is arranged at the top of the screw rod 30;

[0032] The adsorption component 4 includes a pair of mounting arms 40 symmetrically arranged on the left and right sides of the casing 1. On the inner side of the mounting arms 40, a pair of sliders 41 are arranged. The sliders 41 are movably arranged on the sliding rails 10. The two mounting arms 40 are connected by a "U"-shaped frame 42. The "U"-shaped frame 42 covers the outside of the casing 1 and is threadedly arranged on the screw rod 30. Several strong magnets 43 are arranged at the bottom of the two mounting arms 40.

[0033] Preferably, by setting the adjusting component 3 to adjust the height of the adsorption component 4, the device can be applied to the flaw detection operation of steel pipes with different diameters, increasing the versatility and flexibility of the device.

[0034] Steps for installing the probe: First, align one end of the lead wire at the tail of the ultrasonic flaw detection probe with the opening 16 of the casing 1. Then, manually perform an extrusion operation on the extrusion plate 13 to smoothly place the probe into the inside of the casing 1. Then, release the extrusion plate 13. At this time, under the action of the several extrusion springs 12, the extrusion plate 13 will cooperate with the inner wall of the casing 1 to fixedly clamp the probe, ensuring that the probe is firmly installed in the casing 1.

[0035] When detecting the end of a common steel pipe, hold the housing 1 with the probe installed, place the probe at the detection position of the end of the steel pipe, then hold the housing 1 with one hand and turn the knob 32 with the other hand to make the screw 30 rotate forward. When the screw 30 rotates forward, it will drive the "U"-shaped frame 42 to move downward, and then drive the two mounting arms 40 to move downward. When the mounting arms 40 fit against the steel pipe, due to the action of several powerful magnets 43 on the mounting arms 40, they will be adsorbed on the steel pipe, making the probe firmly fixed. After the probe is fixed, the detection operation can be started.

[0036] When detecting some special alloy steel pipes (which cannot be adsorbed by powerful magnetic blocks), first install the probe into the housing 1 according to the above probe installation steps, then hold the housing 1 and place the probe at the detection position of the end of the steel pipe. Subsequently, take out the strap 24, insert the "T"-shaped block 25 at one end of it into the "T"-shaped groove 21 of the mounting block one 20, wind the strap 24 around the steel pipe, and finally pass it out through the slot 23 of the mounting block two 22. After passing out, tighten the strap 24, and at the same time tighten several bolts 26 to clamp and fix the strap 24. Fix the housing 1 at the end of the steel pipe through the strap 24. After the probe is fixed, the detection operation can be carried out.

Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
