[0004] In view of the shortcomings of the prior art, this utility model provides a support for inspecting pipe welds, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a support for inspecting pipe welds, comprising a support body, with two bottom support plates at the bottom of the support body. A first support is provided above the bottom support plate on the left side, and a second support is provided above the bottom support plate on the right side. A rotating mechanism is provided on the side of the second support away from the first support, the rotating mechanism comprising: a rotating collar and a clamping collar. An extension washer is installed on the side surface of the second support, and rotating balls are arranged in a ring array between the rotating collar and the extension washer. Clamping bolts are arranged in a ring array inside the clamping collar. A height adjustment screw is connected inside both the first and second support, and a universal roller is installed at the upper end of the height adjustment screw.

[0006] As a further embodiment of this utility model: guide grooves are provided inside the bottom support plate below the first support bracket and the second support bracket. A drive screw is installed between the inside of the guide groove and the first support bracket and the second support bracket. An adjustment handle is connected to the end of the drive screw on the outside of the bottom support plate.

[0007] As a further improvement of this utility model, a limiting guide rod is connected between the two bottom support plates.

[0008] As a further embodiment of this utility model: the rotating collar and the extending washer are movably connected by the rotating ball bearing, and the rotating collar is fixedly connected to the clamping collar.

[0009] As a further improvement of this utility model: both the first support bracket and the second support bracket are slidably connected to the guide groove.

[0010] As a further improvement of this utility model, both bottom support plates are movably connected to the limiting guide rod.

[0011] As a further embodiment of this utility model: the clamping bolt is rotatably connected to the clamping collar, and the height adjusting screw is rotatably connected to both the second support bracket and the first support bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] After the clamping bolt is pressed against the outside of the pipe to be inspected, by turning the clamping bolt on the outside of the clamping collar, the rotating collar will be controlled by the rotating balls on the outside of the extension washer to rotate the entire rotating mechanism on the outside of the second support, which facilitates the inspection of the weld.

[0014] The positions of the first and second supports inside the guide groove can be adjusted, and the spacing between the two bottom support plates can be adjusted by the limiting guide rods connected between them. Therefore, the support of the first and second supports for pipes of different lengths can be controlled. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, this embodiment provides a support for inspecting pipe welds, including a support body 1. Two bottom support plates 2 are provided at the bottom of the support body 1. A first support frame 3 is provided above the bottom support plate 2 on the left side, and a second support frame 4 is provided above the bottom support plate 2 on the right side. A rotating mechanism 5 is provided on the side of the second support frame 4 away from the first support frame 3. The rotating mechanism 5 includes a rotating collar 501 and a clamping collar 502. The rotating collar 501 and the clamping collar 502 are fixedly connected. An extension washer 401 is installed on the side surface of the second support frame 4. Rotating balls 402 are arranged in a circular array between the rotating collar 501 and the extension washer 401. The rotating collar 501 and the extension washer 401 are movably connected through the rotating balls 402. The rotating collar 501, the rotating balls 402, and the extension washer are all connected in this manner. The 401 as a whole constitutes a bearing structure, so the rotating mechanism 5 as a whole can make a circular motion on the outside of the second support 4. The clamping collar 502 is equipped with a ring array of clamping bolts 503 inside. The clamping bolts 503 are engaged and rotatably connected to the clamping collar 502. By rotating the multiple clamping bolts 503, the pipe placed inside can be clamped. The first support 3 and the second support 4 are both connected to a height adjusting screw 301 inside. The upper end of the height adjusting screw 301 is equipped with a universal roller 302. The height adjusting screw 301 is engaged and rotatably connected to the second support 4 and the first support 3. By rotating the height adjusting screw 301, the pipe placed inside is supported. The universal roller 302 at the upper end of the height adjusting screw 301 can support the pipe and also allow the pipe to move.

[0023] like Figure 2-3As shown, in this embodiment, guide grooves 6 are provided inside the bottom support plate 2 below the first support 3 and the second support 4. The first support 3 and the second support 4 are slidably connected to the guide grooves 6. A drive screw is installed between the guide groove 6 and the first support 3 and the second support 4. An adjustment handle 8 is connected to the end of the drive screw outside the bottom support plate 2. By applying torque to the adjustment handle 8, the drive screw and the first support 3 and the second support 4 are engaged, thereby controlling the movement of the first support 3 and the second support 4 inside the guide groove 6. A limit guide rod 7 is connected between the two bottom support plates 2. Both bottom support plates 2 are movably connected to the adjustment limit guide rod 7. Limit structures are provided at both ends of the limit guide rod 7 inside the bottom support plate 2, which can prevent disengagement when the two bottom support plates 2 are pulled outward.

[0024] The working principle of this utility model is as follows: During use, after inserting the pipe to be inspected into the first support 3 and the second support 4, torque is applied to the height adjusting screw 301 inside the first support 3 and the second support 4. This controls the raising and lowering of the height adjusting screw 301, which in turn supports the pipe via the universal roller 302. Then, torque is applied to the multiple clamping bolts 503 inside the clamping collar 502, pressing the clamping bolts 503 against the outside of the pipe being inspected. Moving the clamping bolts 503 on the outside of the clamping collar 502 rotates the collar 501. Under the action of the rotating ball 402 on the outer side of the extension pad ring 401, the rotating mechanism 5 can be controlled to rotate in a circle on the outer side of the second support 4. Therefore, the rotating mechanism 5 can be used to drive the rotation of the pipe to be inspected, thus facilitating the inspection of the weld. By applying torque to the adjusting handle to control the rotation of the internal drive screw, the position adjustment of the first support 3 and the second support 4 inside the guide groove 6 can be controlled. At the same time, the two bottom support plates 2 can also adjust the spacing through the limiting guide rod 7 connected between them. Therefore, the support of the first support 3 and the second support 4 for pipes of different lengths can be controlled.
