[0030] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0031] Embodiment 1

[0032] Please refer to Figure 1 - Figure 5 , a double-probe frame device for an ultrasonic flaw detector, comprising: a mounting frame 1, two support frames 2 are arranged below the mounting frame 1, two universal wheels are fixedly installed at the bottom of each of the two support frames 2, four insertion columns 3 are fixedly installed at the bottom of the mounting frame 1, and the bottom ends of the four insertion columns 3 are inserted into the insertion slots opened on the support frames 2. First hydraulic rods 4 are fixedly installed on both of the two support frames 2, and the top of the first hydraulic rod 4 is fixedly connected to the mounting frame 1;

[0033] An adjustment assembly 5 is arranged on the mounting frame 1, a telescopic assembly 6 is arranged on the adjustment assembly 5, a rotation assembly 7 is arranged on the telescopic assembly 6, a distance adjustment assembly 8 is arranged at the bottom of the rotation assembly 7, and two probe frames 9 are fixedly installed at the bottom of the distance adjustment assembly 8.

[0034] For the double-probe frame device for an ultrasonic flaw detector provided by the present utility model, during use, through the universal wheels, the device is convenient to move. Then, the first hydraulic rod 4 on the support frame 2 drives the mounting frame 1, so that the mounting frame 1 can stably lift under the action of the insertion columns 3 and the insertion slots, and thus not only can the probe frame 9 contact the object to be detected, but also it can be avoided that when adjusting the distance between the two probe frames 9, contact friction and other situations occur between the probe frame 9 and the detection object. At the same time, with the cooperation of the mounting frame 1, the support frame 2, the insertion columns 3 and the insertion slots, when the distance adjustment assembly 8 and the probe frame 9 are in use, there is no need for manual holding, thus avoiding the situation that the operator's arm shakes due to fatigue, and further ensuring the detection accuracy. Then, according to the shape of the contact object, the rotation assembly 7 drives the distance adjustment assembly 8 to rotate 90°, so that it forms a cross shape with the mounting frame 1, and thus the probe frame 9 is convenient for detecting tubular objects.

[0035] Furthermore, the telescopic assembly 6 includes a second hydraulic rod 61 arranged inside the mounting frame 1, and a fixed frame 62 is fixedly installed at the bottom of the second hydraulic rod 61.

[0036] Specifically, the second hydraulic rod 61 drives the fixed frame 62 to ensure that the probe frame 9 can contact the object to be detected.

[0037] Further, the rotating assembly 7 includes a cross bar 71 penetrating through the fixing frame 62, and the cross bar 71 is rotatably connected to the fixing frame 62. A worm gear 72 is fixedly installed at the top of the cross bar 71, and a first motor 73 is fixedly installed on the inner bottom wall of the fixing frame 62. A worm 74 is fixedly installed at the output end of the first motor 73, and the worm 74 is meshed with the worm gear 72.

[0038] Specifically, the first motor 73 drives the worm 74 to rotate, and then the rotating worm 74 drives the cross bar 71 through the meshed worm gear 72, so that the cross bar 71 can drive the distance adjusting assembly 8 to rotate and adjust, and further facilitate the detection of the tubular object by the detection frame 9.

[0039] In addition, it should be noted that the cross bar 71 is cross-shaped, which can improve the bearing capacity and stability of the cross bar 71.

[0040] Further, the distance adjusting assembly 8 includes a second U-shaped plate 81 fixedly installed at the bottom of the cross bar 71. A bidirectional screw 82 is rotatably connected to the inner side wall of the second U-shaped plate 81. Two connecting blocks 83 are threadedly connected to the outer side wall of the bidirectional screw 82, and two detection frames 9 are respectively fixedly installed at the bottoms of the two connecting blocks 83. A driving mechanism 84 is fixedly installed at the top of the second U-shaped plate 81, and the output end of the driving mechanism 84 is connected to the bidirectional screw 82.

[0041] Specifically, the driving mechanism 84 drives the bidirectional screw 82 to rotate, and then the rotating driving mechanism 84 drives the two connecting blocks 83 threadedly connected to its outer side wall, so as to conveniently adjust the distance between the two detection frames 9.

[0042] Further, the driving mechanism 84 includes a second motor 8401 fixedly installed at the top of the second U-shaped plate 81. A driving synchronous pulley 8402 is fixedly installed at the output end of the second motor 8401. One end of the bidirectional screw 82 penetrates through one side wall of the second U-shaped plate 81 and a driven synchronous pulley 8403 is fixedly installed. The driving synchronous pulley 8402 and the driven synchronous pulley 8403 are tensioned and meshed through a synchronous belt.

[0043] Specifically, the second motor 8401 drives the driving synchronous pulley 8402, and then the rotating driving synchronous pulley 8402 drives the driven synchronous pulley 8403 through the synchronous belt, so that the bidirectional screw 82 can rotate.

[0044] Further, a linear slide rail 11 is fixedly installed on the inner top wall of the second U-shaped plate 81, and the connecting block 83 is slidably connected to the linear slide rail 11 through a slider.

[0045] Specifically, through the linear slide rail 11, it is ensured that the bidirectional screw 82 can stably drive the connecting block 83 to move and adjust.

[0046] Furthermore, the adjusting assembly 5 includes two electric slide rails 51 fixedly installed on the top of the mounting frame 1. A first U-shaped plate 52 is slidably connected to the electric slide rails 51 through sliders, and the second hydraulic rod 61 penetrates and is installed on the first U-shaped plate 52.

[0047] Specifically, the electric slide rails 51 drive the first U-shaped plate 52 to move, so as to facilitate the position adjustment of the distance adjusting assembly 8 that is cross-shaped with the mounting frame 1, ensuring that the detection frame 9 can contact the object to be detected.

[0048] Embodiment Two

[0049] Based on Embodiment One, in this embodiment: annular grooves are provided on both the inner bottom wall of the fixed frame 62 and the disc of the cross rod 71, and the two annular grooves are opposite to each other up and down. A plurality of balls 10 are arranged inside the annular grooves.

[0050] The technical solution provided by this embodiment is that through the annular grooves and the balls 10, the friction between the cross rod 71 and the fixed frame 62 can be reduced.

[0051] Embodiment Three

[0052] Based on Embodiment One, in this embodiment: two T-shaped rods 12 are penetrated and arranged on the first U-shaped plate 52. The T-shaped rods 12 are movably inserted into the first U-shaped plate 52. The bottom of the first U-shaped plate 52 is fixedly connected to the fixed frame 62. A spring 13 is sleeved on the outer side wall of the T-shaped rod 12, and the spring 13 is located above the first U-shaped plate 52.

[0053] The technical solution provided by this embodiment is that through the T-shaped rods 12 and the springs 13, not only can the stability performance during the lifting of the fixed frame 62 driven by the second hydraulic rod 61 be ensured, but also the connection stability effect between the second hydraulic rod 61 and the fixed frame 62 can be improved, avoiding damage to the detection frame 9 due to the rapid descent of the fixed frame 62 when the second hydraulic rod 61 fails.

[0054] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
