Description

Technical Field

[0001] This utility model relates to the field of thickness gauge technology, specifically to an ultrasonic thickness gauge for steel pipes. Background Technology

[0002] Utility model patent CN106885537A discloses an ultrasonic thickness gauge for steel pipes, including a wirelessly connected core control unit and a probe, wherein the probe is an arc-shaped probe. Compared with the prior art, the advantages of this invention are as follows: The ultrasonic thickness gauge provided by this invention adopts wireless communication technology, overcoming the shortcomings of cable connections that cannot adapt to various measurement environments. Furthermore, this invention can automatically process measurement data, improving measurement efficiency. In addition, this invention can also record and save measurement results.

[0003] Currently, the connection between the socket and plug of ultrasonic thickness gauges for steel pipes lacks a protective limit function after insertion. As a result, the connection between the socket and plug is prone to detachment when pulled, affecting the stability of the limit installation. Moreover, the sudden detachment of the socket and plug connection will also affect the performance of the ultrasonic thickness gauge. In addition, the thickness gauge is mostly controlled by hand and limited to the outside of the steel pipe for thickness measurement. However, the unstable hand limit affects the thickness measurement effect. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic thickness gauge for steel pipes, which solves the problems of limiting the connection between the socket and the plug and limiting the thickness gauge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic thickness gauge for steel pipes, comprising a thickness gauge, a plurality of sockets fixedly connected to the upper end of the thickness gauge, a plug slidably connected inside the sockets, a wire fixedly connected to the plug, a test line fixedly connected to the wire, a limit mechanism provided on the wire, a thickness gauge fixedly connected to one end of the test line, and a clamping mechanism provided on the thickness gauge.

[0006] Preferably, the limiting mechanism includes a retaining sleeve, the wire is slidably connected to the retaining sleeve, an anti-slip ring is fixedly connected to the outer side of the retaining sleeve, and a threaded ring is fixedly connected to the retaining sleeve.

[0007] Preferably, the plug is connected to the inside of the sleeve, and the threaded ring is connected to the outside of the socket by a threaded rotation.

[0008] Preferably, the ferrule is fixedly connected to a rubber sleeve, the ferrule is fixedly connected to a sleeve, the rubber sleeve and the sleeve are fixedly connected, and the wire slides through the inside of the rubber sleeve.

[0009] Preferably, the clamping mechanism includes a protrusion, the thickness gauge is fixedly connected to the protrusion, the upper end of the protrusion is fixedly connected to a slide rod, and the upper end of the slide rod is fixedly connected to an anti-detachment block.

[0010] Preferably, the slide rod is slidably connected to a sliding sleeve, the sliding sleeve is fixedly connected to a connecting block, the connecting block is fixedly connected to a pressing block, and the pressing block is fixedly connected to an anti-slip pad.

[0011] Preferably, the slide rod is slidably connected to a nut, and the nut is connected to the upper end of the slide sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a ferrule to connect the threaded ring, which allows the ferrule to be rotated to drive the threaded ring to rotate and connect to the outside of the socket. The ferrule limits the plug and prevents it from moving away from the plug, thereby preventing the socket from separating from the plug and increasing the stability of the installation. The anti-slip ring makes it easy to rotate the ferrule and prevents slippage from affecting the rotation of the ferrule.

[0013] 2. This utility model uses a protrusion to limit the sliding rod, which slides into a sliding sleeve. The sliding sleeve is connected to a pressing block via a connecting block. The pressing block presses the anti-slip pad tightly against the inner wall of the steel pipe, while the thickness gauge is tightly against the outer side of the steel pipe, thus clamping the steel pipe from both inside and outside. The sliding sleeve is limited by a nut to prevent it from moving, thereby preventing the pressing block from moving and limiting the thickness gauge to prevent it from detaching from the outer side of the steel pipe, thus avoiding the trouble caused by manual limiting.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 An ultrasonic thickness gauge for steel pipes includes a thickness gauge 1. Multiple sockets 2 are fixedly connected to the upper end of the thickness gauge 1. A plug 3 is slidably connected inside each socket 2. A wire 4 is connected to the thickness gauge 1 via the slidable connection between the socket 2 and the plug 3. A test lead 5 is fixedly connected to the plug 3. A limit mechanism 6 is provided on the wire 4. A thickness gauge 7 is fixedly connected to one end of the test lead 5. The thickness gauge 7 is existing technology and will not be described further in this technical solution. The thickness gauge 7 is equipped with a clamping mechanism 8. This technical solution improves upon the problems mentioned in the background technology. Other technical problems in this technical solution are existing technologies and will not be described further in this technical solution.

[0018] Please see Figure 1 , Figure 2 , Figure 4 The limiting mechanism 6 includes a retainer 61, a wire 4 is slidably connected to the retainer 61, and an anti-slip ring 62 is fixedly connected to the outside of the retainer 61. The anti-slip ring 62 facilitates the rotation of the retainer 61 and prevents slippage during rotation. A threaded ring 63 is fixedly connected to the retainer 61, and the plug 3 is connected to the inside of the retainer 61. The threaded ring 63 is rotatably connected to the outside of the socket 2 via threads. A rubber sleeve 64 is fixedly connected to the retainer 61, and a sleeve 65 is fixedly connected to the retainer 61. The sleeve 65 reinforces and protects the rubber sleeve 64. The rubber sleeve 64 and the sleeve 65 are fixedly connected, and the wire 4 slides through the inside of the rubber sleeve 64.

[0019] Please see Figure 1 , Figure 2 , Figure 3 The clamping mechanism 8 includes a protrusion 81. The thickness gauge 7 is fixedly connected to the protrusion 81. The upper end of the protrusion 81 is fixedly connected to a slide rod 82. The upper end of the slide rod 82 is fixedly connected to an anti-detachment block 83. By setting the anti-detachment block 83, one end of the slide rod 82 is limited to prevent the slide sleeve 84 from detaching from the slide rod 82. The slide rod 82 is slidably connected to the slide sleeve 84. The slide sleeve 84 is fixedly connected to a connecting block 85. The connecting block 85 is fixedly connected to a pressing block 86. The pressing block 86 is fixedly connected to an anti-slip pad 87. The slide rod 82 is slidably connected to a nut 88. The nut 88 is connected to the upper end of the slide sleeve 84.

[0020] The specific implementation process of this utility model is as follows: Slide the plug 3 so that the plug 3 slides into the socket 2, and then the socket 2 and the plug 3 are connected. Then rotate the sleeve 61. The anti-slip ring 62 increases the anti-slip property when rotating the sleeve 61, making it easier to rotate the sleeve 61. Then the threaded ring 63 is connected to the outside of the socket 2 through the threaded rotation, and then the socket 2 and the plug 3 are fixed in place to prevent them from coming apart. The rubber sleeve 64 protects the connection between the wire 4 and the plug 3 to prevent breakage and separation. When the thickness gauge 7 needs to be installed, slide the sliding sleeve 84, causing the connecting block 85 to move, and then the pressing block 86 to move. When the pressing block 86 presses the anti-slip pad 87 tightly against the inner side of the steel pipe, while the thickness gauge 7 is tightly against the outer side of the steel pipe, then rotate the nut 88, which will rotate and press down on the upper end of the sliding sleeve 84, thereby fixing the sliding sleeve 84 in place. This prevents the pressing block 86 from moving and prevents the thickness gauge 7 from separating from the steel pipe, thus allowing the testing work to be carried out.
