Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pipeline support hanger, and particularly relates to a steam-water pipeline support hanger load online monitoring structure. BACKGROUND

[0002] The performance of the in-service pipeline support hanger is generally tested by testing the actual load of the support hanger, and then calculating the support hanger spring stiffness, load constancy and other parameters by relevant formulas, so as to evaluate the actual performance of the in-service support hanger. The method for testing the load of the hanger mainly includes two kinds. One is to inversely deduce the load by testing the vibration characteristics of the hanger. The other is to directly arrange a strain sensor, test the strain of the hanger and convert it into the load of the hanger. The latter is more used in engineering projects due to its advantages such as easy operation and data continuity.

[0003] In actual operation, the strain sensor is usually fixed on the hanger by welding or bonding. The strain sensor is zeroed under the premise that the load of the hanger is fully released. After the hanger is reloaded, the longitudinal strain on the surface of the strain sensor is tested to obtain the tension of the hanger. However, it is relatively complex and time-consuming to directly paste the strain gauge or weld the sensor on the hanger, and it is also not conducive to large-scale load testing of the hanger in the hanger inspection. Therefore, it is particularly urgent to invent an online monitoring mechanism for conveniently detecting the load capacity of the support hanger. SUMMARY

[0004] In view of the above problems, the steam-water pipeline support hanger load online monitoring structure provided by the embodiments of the application can test the load performance of the hanger online by adopting a detachable strain sensor, and the installation is convenient and the work efficiency is greatly improved. The technical solution is as follows:

[0005] The steam-water pipeline support hanger load online monitoring structure provided by the application comprises a fixed seat connected with a hanger and a strain sensor detachably connected with the fixed seat. The fixed seat is spaced apart and comprises two fixed seats fixed at two ends of the hanger. The strain sensor spans the two fixed seats, and the two ends of the strain sensor are connected with the two fixed seats. The hanger is deformed under stress to drive the two fixed seats to produce relative displacement, and then the strain sensor is stretched to obtain the strain of the hanger.

[0006] For example, in the steam-water pipeline support hanger load online monitoring structure provided by one embodiment, a grating strain gauge is pasted on the strain sensor. When the hanger is deformed under stress to stretch the strain sensor, the stretching amount of the strain sensor is captured by the grating strain gauge, and then the strain of the hanger is obtained.

[0007] For example, in one embodiment, the strain sensor is an arcuate strain sensor, comprising a main body and connecting portions at both ends of the main body, and the connecting portions are connected with the two fixing bases respectively.

[0008] For example, in one embodiment, the fixing base is connected with the suspender through the flexible metal binding ring.

[0009] For example, in one embodiment, the inner wall of the flexible metal binding ring is provided with an anti-skid rubber layer, so that the flexible metal binding ring is tightly attached to the outer wall of the suspender, thereby avoiding the sliding of the fixing base on the suspender.

[0010] For example, in one embodiment, the side of the fixing base away from the flexible metal binding ring is provided with a screw rod, and the connecting portions at both ends of the strain sensor are provided with first screw holes corresponding to the screw rod, and the connecting portions at both ends of the strain sensor are detachably connected with the two fixing bases through the screw rod and the first screw holes.

[0011] For example, in one embodiment, the structure further comprises a connecting rod, and the connecting rod is provided with two second screw holes at intervals.

[0012] For example, in one embodiment, the distance between the two second screw holes is the same as the distance between the two fixing bases.

[0013] For example, in one embodiment, the flexible metal binding ring can wrap multiple suspenders to measure the deformation of the multiple suspenders under stress.

[0014] For example, in one embodiment, the fixing base comprises a main body and a connecting frame body connected with the main body on one side of the main body, and the flexible metal binding ring is arranged on the side of the connecting frame body away from the main body.

[0015] The beneficial effects brought by the steam and water pipeline support and hanger load online monitoring structure of the present application are as follows: when the load performance of the hanger is tested, the tension causes the hanger to produce strain, and then the two fixed seats fixedly installed on the hanger produce relative displacement, the relative displacement stretches the strain sensor installed on the fixed seat, the stretching amount of the strain sensor is captured by the grating strain gauge on the arc-shaped strain sensor, and finally the hanger strain amount is obtained; the strain sensor is separated from the hanger through the fixed seat, the strain sensor is detachably installed on the hanger for load testing, the problems such as complex operation, long time consumption and being not conducive to load testing on a large-scale hanger in the support and hanger inspection in the traditional technology caused by directly pasting strain gauges or welding arc-shaped sensors on the hanger are avoided, the present application is easy to install, the work efficiency is greatly improved, and load testing can be quickly performed on hangers of various specifications.

Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] This application provides an online monitoring structure for the load of steam and water pipeline supports and hangers, such as... Figures 1-3 As shown, the system includes a fixed base 200 connected to a boom 100 (not shown) and a strain sensor 300 detachably connected to the fixed base 200. Two fixed bases 200 are spaced apart and fixed to both ends of the boom 100. The strain sensor 300 spans the two fixed bases 200, with both ends connected to the two fixed bases 200 respectively. When the boom 100 is subjected to force, it deforms, causing relative displacement between the two fixed bases 200, which in turn stretches the strain sensor 300 to obtain the strain of the boom 100. According to the above embodiment, the two fixed bases 200 are first installed on the boom 100, and then the strain sensor 300 is installed on the fixed base 200. During the test, the tension causes strain in the boom 100, which in turn causes relative displacement in the two fixed seats 200 fixedly installed on the boom 100. This relative displacement stretches the strain sensor 300 installed on the fixed seat 200, and the strain of the boom is finally obtained based on the stretch of the strain sensor 300.

[0024] For example, in the online load monitoring structure for the steam pipe support provided in one embodiment, a grating strain gauge is attached to the strain sensor 300. When the rod 100 is subjected to force and deforms, causing the strain sensor 300 to stretch, the stretching amount of the strain sensor 300 is captured by the grating strain gauge, thereby obtaining the strain of the rod 100.

[0025] For example, in the online load monitoring structure for the steam and water pipe support provided in one embodiment, such as Figure 2As shown, the strain sensor 300 is an arcuate strain sensor, comprising a main body 310 and connecting portions 320 located at both ends of the main body 310, and the two connecting portions 320 are connected with the two fixing bases 200 respectively. Wherein, the main body 310 protrudes to one side relative to the connecting portions 320, so as to form an arc shape.

[0026] For example, in the steam and water pipeline support load online monitoring structure provided by an embodiment, as shown in Figure 3 As shown, the fixing base 200 is provided with a flexible metal binding ring 230, and the fixing base 200 is connected with the suspender 100 through the flexible metal binding ring 230. According to the above embodiment, the flexible metal binding ring 230 can be completely opened and then bound to the measured support suspender 100. The flexible metal binding ring 230 is connected with the suspender 100, which can meet the monitoring needs of different sizes of the suspender 100, has a wide range of use, and has high practicability.

[0027] For example, in the steam and water pipeline support load online monitoring structure provided by an embodiment, as shown in Figure 3 As shown, an anti-skid rubber layer 231 is arranged on the inner wall of the flexible metal binding ring 230, so that the flexible metal binding ring 230 is tightly attached to the outer wall of the suspender 100, thereby avoiding the sliding of the fixing base 200 on the suspender 100. According to the above embodiment, the anti-skid rubber layer 231 is arranged on the inner wall of the flexible metal binding ring 230, so that when the fixing base 200 and the suspender 100 are bound together through the flexible metal binding ring 230, the fixing base 200 will not slide on the suspender 100. Under the fastening force of the anti-skid rubber layer 231, the flexible metal binding ring 230 is tightly attached to the outer wall of the suspender 100, thereby avoiding the change of the distance between the two fixing bases 200 due to the loosening and sliding of the fixing base 200 on the suspender 100, so that the strain sensor 300 is stretched and deformed, thereby interfering with the detection of the strain sensor 300, and the strain sensor 300 measures the strain of the suspender 100 under stress more accurately.

[0028] For example, in the steam and water pipeline support load online monitoring structure provided by an embodiment, as shown in Figure 1 , Figure 3As shown, a screw rod 240 is arranged on the side of the fixing seat 200 away from the flexible metal binding ring 230, and a first screw hole 321 corresponding to the screw rod 240 is arranged on the connecting part 320 at both ends of the strain sensor 300, and the connecting part 320 at both ends of the strain sensor 300 is detachably connected with the two fixing seats 200 through cooperation of the screw rod 240 and the first screw hole 321. According to the above embodiment, the strain sensor 300 in the application is detachably connected with the fixing seat 200 through threaded cooperation, which is convenient to install and greatly improves work efficiency. The strain sensor can be quickly installed on various types of suspender for load testing, avoiding the complex operation and long time consumption caused by directly pasting strain gauges or welding arc-shaped sensors on the suspender 100 in the traditional technology, and is not conducive to load testing on a large-scale suspender in the support hanger inspection.

[0029] For example, in the steam and water pipeline support hanger load online monitoring structure provided by one embodiment, as shown in Figure 1 As shown, a connecting rod 400 is further arranged, and two second screw holes 410 are arranged on the connecting rod 400 at intervals.

[0030] For example, in the steam and water pipeline support hanger load online monitoring structure provided by one embodiment, as shown in Figures 1-2 As shown, the interval between the two second screw holes 420 is the same as the interval between the two fixing seats 200, and the interval between the two fixing seats 200 is the same as the interval between the two first screw holes 321 on the connecting part 320 at both ends of the strain sensor 300. According to the above embodiment, by arranging the connecting rod 400, the screw rod 240 of the two fixing seats 200 is respectively installed on the two second screw holes 410 on the connecting rod 400, so as to limit the interval between the two fixing seats 200, then the flexible metal binding ring 230 on the fixing seat 200 is bound with the suspender 100, and then the connecting rod 400 is removed, and the screw rod 240 of the two fixing seats 200 is connected with the first screw hole 321 on the connecting part 320 at both ends of the strain sensor 300, so as to install the strain sensor 300 on the two fixing seats 200.

[0031] For example, in the steam and water pipeline support hanger load online monitoring structure provided by one embodiment, a plurality of suspenders 100 can be wrapped in the flexible metal binding ring 230 to measure the deformation amount of the plurality of suspenders 100 caused by stress. According to the above embodiment, the plurality of suspenders 100 can be installed together with the fixing seat 200, so as to measure the load of the plurality of suspenders 100, and meet the performance testing of the combination of the plurality of suspenders 100.

[0032] For example, in the steam and water pipeline support hanger load online monitoring structure provided by one embodiment, as shown in Figure 3As shown, the fixing base 200 comprises a body 210 and a connecting frame 220 connected to the body 210, and the flexible metal binding ring 230 is arranged on the side of the connecting frame 220 away from the body 210. According to the above embodiment, by arranging the connecting frame 220, the hollow area in the middle of the connecting frame 220 provides space for the screwing of the screw rod 240, thereby installing the fixing base 200 on the connecting rod 400 or installing the strain sensor 300 on the fixing base 200.
