Description

Technical Field

[0001] The invention relates to the field of measurement technology, and in particular to a building construction detection device. Background Art

[0002] Pipeline construction in construction mainly includes planning and design, material selection, pipeline laying, connection and sealing, inspection and testing, as well as insulation and protection. In the planning stage, the pipeline layout is formulated according to the architectural drawings; suitable materials are selected to meet corrosion resistance and pressure bearing capacity; pipelines are laid according to the design and the slope is ensured to meet drainage requirements; joints are ensured to be sealed through welding or threaded connections; pressure testing and leak detection are carried out after completion to ensure safety; insulation treatment is carried out when necessary, especially for hot and cold water pipes, to improve energy efficiency.

[0003] Before the pipe fittings are transported to the construction site, the outer wall of the pipe fittings may be hit during the transportation process, causing dents on the outer wall of the pipe fittings. When picking up the pipe fittings, if the pipe fittings fall, the pipe fittings will come into contact with protrusions on the ground and cause dents. Similarly, when producing pipe fittings, possible process defects may also cause protrusions on the inner wall of the pipe fittings. Such dents and protrusions will change the structural strength of the pipe fittings. Moreover, if the pipe fittings are directly installed without measurement, the flow of liquid inside the pipe fittings will be uneven during use, affecting their use. In addition, the structural strength of the depressed part of the pipe fittings will change. When the pipe fittings are subjected to greater pressure or impact, the depressed area may become a weak point, causing the pipe fittings to rupture. Therefore, it is necessary to measure the inner wall of the pipe fittings before the construction of the pipe fittings. For example, a steel pipe diameter measuring device for construction quality inspection disclosed in publication number CN110672054A does not detect the dents caused by the above-mentioned pipe fittings, and the resulting measurement results are not sufficient to support the normal use of the pipe fittings. Summary of the invention

If the diameter of the pipe fitting is too large or the pipe fitting is bent as a whole, it will drive the two arc clamp rings or one of the arc clamp rings to move. The moving arc clamp ring will drive the sliding clamp head to contact the fixed clamp head to energize the two proximity sensors, thereby transmitting power to energize the electromagnet. The electromagnet drives the magnet and the guide rod to rotate in the rotating gap through magnetic force. After the outer wall of the pipe fitting is inspected, the pipe fitting will be transferred to the upper end face of the mobile vehicle and rolled and conveyed through the adjusted guide rod to determine whether the outer wall of the pipe fitting is too large or the pipe fitting is bent as a whole.

[0024] Third, after the inner wall of the pipe is inspected, the defective part of the pipe can be cut off by the provided cutting machine, and at the same time, the provided first sliding head drives the conical rotating wheel to inspect the inside of the cut part of the pipe to detect whether the cut part of the pipe is sunken due to cutting.

In this way, when inspecting the cut part, the assembly problem of the pipe with other pipes after cutting can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] A second driving source 504 is fixedly installed at an upper position on one side of the third supporting plate 502, and a rotating tooth 505 is fixedly installed on the output end of the second driving source 504 through the third supporting plate 502. The rotating tooth 505 is meshed with the second rotating gear sleeve 503. Through the setting of the detection head 510, the detection head 510 can be driven to move on the inner wall of the pipe fitting, and contact the inner wall of the pipe fitting through the marking head 512. When it contacts the protrusion, it will mark it, and then after exiting the inner wall of the pipe fitting, the color of the marked place will be detected through the color sensor 516 (the color sensor 516 can accurately identify the color of the object and convert it into an electrical signal).

[0058] The working principle of the present invention is as follows:

[0059] The pipe is placed inside the first support plate 201 and the second support plate 202, and the driving device 206 drives the conveying roller 203 and the rotating roller 205 to drive the pipe to be conveyed. The driving device 206 is driven by a controller (not shown in the drawings), a motor, a transmission gear and a bevel gear. The transmission gear is used to drive the first rotating gear sleeve 204 to rotate, and the bevel gear is suitable for driving one of the two provided conveying rollers 203. At the same time, when the driving bevel gear is rotated, it is driven by an electromagnetic clutch. The pipe driven to move and rotate will move toward the top of the mobile vehicle 1 and contact the arc-shaped clamping ring 312. The two arc-shaped clamping rings 312 will contact the outer wall of the pipe. In addition, Teflon tape is attached to the inner wall of the arc-shaped clamping ring 312 to prevent the pipe from being damaged by excessive friction when it contacts the arc-shaped clamping ring 312.

[0060] Measurement of the outer wall of the pipe fitting: When the diameter of the pipe fitting is large or the pipe fitting is bent as a whole, the pipe fitting will push the two arc-shaped clamping rings 312 or one of them to slide. When the arc-shaped clamping ring 312 slides, it will drive the sliding rod 304 to slide on the inner wall of the vertical plate 302 and compress the first spring 311. The moving sliding rod 304 will drive the sliding clamp 306 to slide on the outer side of the horizontal plate 303 and drive the proximity sensor 308 to approach the fixed clamp 307 for sensing (through the provided fastening bolts 309, the fixed clamp 307 can be sensed on the outer side of the horizontal plate 303). The proximity sensor 308 senses the proximity of the fixed clamp 307 and transmits a signal to the electromagnet inside the guide box 316 through the controller to make the electromagnet conductive. The conductive electromagnet generates a magnetic force to attract the magnet 315 to rotate, and the magnet 315 drives the guide rod 314 to rotate through the connecting rod (when the electromagnet does not attract the magnet 315 to rotate, the magnet 315 rotates to the other side in the rotation gap, see the attached Figure 5 ), let the guide rod 314 rotate to the other side of the original rotation direction at the top of the mobile vehicle 1, so as to determine whether the pipe is qualified, and then the pipe will be transmitted to the upper end surface of the unloading base 313 and rotate to the other side of the original rotation direction through the angle adjusted by the guide rod 314 to unload (in the process of detecting pipes, the electromagnet needs to be conductive after an error occurs in the pipe, and the electromagnet needs to maintain the conductive state for a set time until the pipe is unloaded. In this process, when the controller transmits power to the electromagnet, it can use a time relay (the time relay is a prior art and is not drawn in the attached figure) to keep the electromagnet powered on for a set time and then turn off the power and reset to the original state);

[0061] 509 is a kind of pipe fitting which is used for marking. When the telescopic screw 509 moves to a limited position, the second driving source 504 will rotate in the opposite direction, driving the second rotating gear sleeve 503 to rotate in the opposite direction, and the second rotating gear sleeve 503 will drive the telescopic screw 509 to rotate in the opposite direction and push out the inner wall of the pipe. In this process, the color sensor 516 will detect the position of the marking pigment, and the set lighting lamp 517 will illuminate the inner wall of the pipe. When the color sensor 516 detects the pigment mark, it will be connected to the input end of the alarm device (not shown in the accompanying drawings) and let the alarm device sound an alarm, thereby indicating that there is a protrusion in the inner wall of the pipe. It should be noted that before working, pigment can be injected into the liquid storage capsule 508, and the expanded liquid storage capsule 508 will compress the pigment due to its own elastic force and make the pigment have a certain liquid pressure. When the detection head 510 detects that the inner wall of the pipe is concave, the expanded liquid storage capsule 508 will allow the pigment to be sprayed out quickly from the liquid outlet groove 514 under a certain liquid pressure for marking;

[0062] After the inner wall of the pipe is detected to be unqualified (the unqualified pipe may only exist partially, while the rest of the pipe is still intact, so the defective part of the pipe needs to be cut off), the linear drive installed on one side of the U-shaped frame 402 is turned on (see attached Figure 6 ) drives the cutting machine 403 to descend, and at the same time closes the electromagnetic clutch to stop driving the pipe to move, so that the pipe is still being driven to rotate, and the cutting machine 403 will cut the rotating pipe, and the remaining pipes that are not detected due to the length limitation of the telescopic screw 509 can be driven by the conveying component 2 to be conveyed and then detected;

[0063] It should be noted that when cutting off a pipe with defects, the cut end of the pipe needs to be inspected. Inspecting the deformation of the cut end of the pipe can avoid errors in the installation of the pipe. By turning on the first driving source 405 to drive the rotating column 404 to rotate, the rotating column 404 will drive the connecting disk 407 and the detection disk 410 to rotate through the first fixed bracket 406. The rotation angle is 90°, so that the detection disk 410 is engaged with the cut end of the pipe. When the pipe is driven to rotate again, the inner wall of the pipe will contact the conical rotating wheel 412. When the cut end of the pipe is concave inward due to cutting deformation, the first sliding head 411 and the first contact rod 413 will be driven to contact the first trigger sensor 416. The first trigger sensor 416 is connected to the sound and light alarm 408 by signal, so that the sound and light alarm 408 buzzes and lights up, thereby indicating that the cut end of the pipe is deformed. When the rotating column 404 is driven to rotate, the second fixed bracket 41 will also be driven 7 rotates with the linkage bracket 418, and the linkage bracket 418 drives the transmission bracket 420 to rotate during the rotation process. The rotating transmission bracket 420 drives the T-shaped rod 419 to slide on the outer wall of the round rod 422, and the sliding T-shaped rod 419 drives the moving box 424 to move toward the outer wall of the pipe fitting, and makes the contact roller 427 contact the outer wall of the pipe fitting cutout. As the pipe fitting is continuously driven to rotate, the pipe fitting cutout protrudes outward due to cutting deformation, which drives the contact roller 427 and the second sliding head 426 to make the first slider 425 slide in the inner wall of the moving box 424. Therefore, the moving box 424 compresses the fourth spring 428 and drives the second contact rod 429 to contact the second trigger sensor 430. The second trigger sensor 430 connects with the signal of the sound and light alarm 408 to make the sound and light alarm 408 buzz and light up, thereby indicating that the pipe fitting cutout is deformed, and the pipe fitting is determined to be scrapped and cannot be used.
