Description

Technical Field

[0001] The utility model relates to the technical field of pipeline measurement, in particular to a wall thickness measuring device which is convenient to clamp. Background Art

[0002] Before installing the pressure pipeline, its wall thickness needs to be tested. If the wall thickness of the pipeline is unqualified, it is easy to cause an accident. When testing the wall thickness of the pipeline, an ultrasonic thickness gauge is often used. When using it, the probe of the ultrasonic thickness gauge is placed on the outer wall of the pipeline for detection. When testing the pipeline, the single-point measurement method can be used to continuously measure along the specified route with a spacing of no more than five millimeters. Most existing ultrasonic thickness gauges have a single-point measurement mode or a continuous measurement mode, and have a data storage function;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model discloses a wall thickness measuring device which is convenient to clamp, such as Figure 1-5 As shown, it includes a frame 100, a clamping mechanism 200 is arranged inside the frame 100, and the clamping mechanism 200 is matched with two auxiliary mechanisms 400;

When in use, the two ends of the pipeline are respectively supported by the two auxiliary mechanisms 400, and then the pipeline is placed inside the frame 100, and then the two clamping plates 210 are moved toward each other, so that the pipeline is driven by the two clamping plates 210 and squeezed toward the middle of the frame 100. The two rotating rods 220 are moved so that the pipeline is supported by the driving wheels 240 on the two rotating rods 220 and is stuck between the two driving wheels 240 on the same rotating rod 220. The two clamping plates 210 are used to limit the pipeline to prevent the pipeline from falling from the driving wheels 240 on the rotating rod 220. Then, the probes of the two ultrasonic thickness gauges are fixed to the inside of the connecting grooves 211 on the two clamping plates 210 by glue or connecting pieces. The two rotating rods 220 are rotated to drive the pipeline to move through the inside of the frame 100, so that the pipeline is continuously measured by the probe when it moves. It is more convenient for users to continuously measure the side thickness of longer pipelines, and data comparison can be performed by continuously measuring different parts of the pipeline. When the probe is detecting, the pipeline surface should be cleaned in advance to prevent protrusions on it from affecting the probe detection, and coupling agent can be applied to the pipeline surface in advance to improve the probe detection effect.

[0026] Two screw-on holes 103 are provided on the top surface of the frame 100, and screw-on rods 310 are screwed inside the two screw-on holes 103.

A plurality of abutting wheels 320 are rotatably connected between the two arms of the U-shaped plate 300. When in use, the two screw-on rods 310 are manually rotated to drive the U-shaped plate 300 to move downward, so that the plurality of abutting wheels 320 contact the pipeline, thereby pressing the pipeline, and pressing the pipeline between the two driving wheels 240 on the same rotating rod 220, thereby improving the positioning effect of the pipeline.

[0027] Two support plates are fixedly connected to both sides of the top and bottom of the frame 100, and an adjusting screw 250 is rotatably connected between the two support plates on the same side of the frame 100. Threaded holes 212 are provided at both ends of the two clamping plates 210. The inner walls of the two threaded holes 212 on the same clamping plate 210 are respectively screwed with the outer walls of the two adjusting screws 250.

A power box 260 is fixedly connected to one side of the frame 100, and a power motor is arranged inside the power box 260. The motor shaft of the power motor passes through the adjacent support plate and is fixedly connected to the other end of the adjacent adjusting screw 250. The middle part of the outer wall of the two rotating rods 220 is fixedly sleeved with a driven toothed belt pulley 251. And the two driven toothed pulleys 251 are both located between the two adjacent driving wheels 240, and a driven toothed belt 252 is rotatably sleeved between the outer side walls of the two driven toothed pulleys 251. A driving motor 230 is fixedly connected to one side of the frame 100, and one end of a rotating rod 220 passes through one side of the frame 100 and is fixedly connected to the motor shaft of the driving motor 230. When in use, the starting power motor can drive the two adjusting screws 250 to rotate synchronously through the auxiliary toothed belt 242 and the auxiliary toothed pulley 241. The two adjusting screws 250 are both positive and negative tooth screws, so that when the two adjusting screws 250 rotate, the two splints 210 can be driven to move toward or away from each other, and the driving motor 230 can be started and the two rotating rods 220 and the driving wheel 240 thereon can be driven to rotate synchronously through the driven toothed pulley 251 and the driven toothed belt 252, so that the driving wheel 240 drives the pipeline to move.

[0028] The two driving wheels 240 on the same rotating rod 220 are fixedly connected to the opposite sides with a connecting tube 243, and the inner side walls of the connecting tube 243 are fixedly sleeved with the outer side walls of the adjacent rotating rod 220. The connecting tubes 243 are all truncated cone-shaped structures. Through the inclined surface of the connecting tube 243, the pipe inserted into the frame 100 is squeezed and moved by the clamping plate 210, and it is easier to move along the inclined surface of the connecting tube 243 to between the two driving wheels 240 on the same rotating rod 220.

The top surface of the support plate 420 is an arc-shaped surface. When in use, the two ends of the pipeline can be placed on the top of the support plates 420 on the two auxiliary mechanisms 400, and then the user will wrap the strap 430 around the pipeline and tie it to the connecting ring 440, so that the two ends of the pipeline are tied to the top of the two support plates 420, and the bottom surface of the frame 100 and the bottom surfaces of the two movable plates 410 are connected to universal wheels. When the pipeline is driven to move by the driving wheel 240, the pipeline can drive the two support plates 420 and the movable plate 410 to move synchronously, and the pipeline is always supported by the two support plates 420.

[0030] Working principle: When in use, the pipe is passed through the frame 100, and then the two ends of the pipe can be placed on the top of the support plates 420 on the two auxiliary mechanisms 400. Then the user passes the strap 430 around the pipe and ties it to the connecting ring 440, so that the two ends of the pipe are tied to the top of the two support plates 420. Then the power motor can be started to drive the two adjusting screws 250 to rotate synchronously through the auxiliary toothed belt 242 and the auxiliary toothed pulley 241. The two adjusting screws 250 are both positive and negative threaded screws, so that when the two adjusting screws 250 rotate, they can drive the two clamping plates 210 to move toward each other, so that the two clamping plates 210 press the pipe to move toward the middle of the frame 100, so that the pipe is supported by the driving wheels 240 on the two rotating rods 220 and stuck between the two driving wheels 240 on the same rotating rod 220;

[0031] Then, the probes of the two ultrasonic thickness gauges are fixed to the inside of the connecting grooves 211 on the two clamping plates 210 by glue or connecting pieces, and the two screwing rods 310 are manually rotated to drive the U-shaped plate 300 to move downward, so that the multiple abutting wheels 320 abut against the pipeline, thereby pressing the pipeline and pressing the pipeline between the two driving wheels 240 on the same rotating rod 220. The driving motor 230 is started and the two rotating rods 220 and the driving wheels 240 thereon are driven to rotate synchronously through the driven toothed belt pulley 251 and the driven toothed belt 252, so that the driving wheel 240 drives the pipeline to move, so that the pipeline is continuously thickened by the probe when it moves, which is more convenient for users to continuously thicken longer pipelines.
