A first handle 1108 is fixedly connected to the outer end of the first screw 1107. By turning the first handle 1108, the first screw 1107 is driven to rotate, thereby driving the first movable plate 1104 to move and pushing the clamping plate 1102 to move laterally through the first spring 1105, which cooperates with one side of the inner wall of the U-shaped plate 1101 to clamp the steel plate 14 on the upper part of the support. The first spring 1105 generates a constant force to prevent the clamping from loosening during the use of the equipment.

[0036] The self-balancing reflector 12 includes: a reflector 1201, an upper bracket 1202, a lower bracket 1203, a hinge shaft 1204, a base plate 1205, a servo motor 1206, a gyroscope 1207, a microcontroller 1208, and an L-shaped connecting arm 1209.

The reflective surface of the upper end of the reflector 1201 faces the output of the laser sensor 10. Since this measuring device requires external force to pull the chain hoist 5, the support rod 15 will sway. In order to reduce the error, the gyroscope 1207 is used to measure the sway angle of the support rod 15, and then the servo motor 1206 is used to adjust the reflector 1201 so that the reflector 1201 is always in a horizontal state. The angle measured by the gyroscope 1207 is also used to correct the distance of the rod extension, further reducing the error.

[0037] The clamping device 13 includes an L-shaped base 1301, a first gripper 1302, a second pin 1303, a gripper arm 1304, a second gripper 1305, a first pin 1311, and a gripper drive mechanism. The L-shaped base 1301 has a first mounting groove 13011 and a second mounting groove 13012 respectively on the side of the horizontal end facing the support and the side of the vertical bottom end facing the support. The first gripper 1302 is rotatably connected to the first mounting groove 13011 through the first pin 1311. The second gripper 1305 is fixedly connected to the outer end of the gripper arm 1304. The inner end of the gripper arm 1304 is rotatably connected to the second mounting groove 13012 through the second pin 1303.

[0038] The gripper drive mechanism includes: a second screw 1306, a second handle 1307, a second movable plate 1308, a second guide rod 1309, a second spring 1310, a second bearing 1312, and a third pin 1313. One side of the second screw 1306 is rotatably connected to the middle of the horizontal part of the L-shaped base 1301 via the second bearing 1312. A through hole 13041 is provided in the middle of the gripper arm 1304. Two rectangular holes 13042 are symmetrically provided on the upper and lower sides of the through hole 13041 on the gripper arm 1304. The second screw 1306 movably passes through the through hole 13041 and is threadedly connected to a threaded hole in the middle of the second movable plate 1308. Two third sliding holes are symmetrically provided on the upper and lower sides of the threaded hole on the second movable plate 1308. Two second guide rods 1309 and two third pins 1313 are provided. One end of each of the two second guide rods 1309 is connected via two... A third pin 1313 is hinged in two rectangular holes 13042. The other ends of the two second guide rods 1309 slide through the two third sliding holes respectively. A second spring 1310 is also sleeved on the second guide rod 1309, with its two ends pressing against the opposite side of the second movable plate 1308 and the claw arm 1304 respectively. A second handle 1307 is fixedly connected to the end of the second screw 1306 away from the second movable plate 1308. The first mounting groove 13011 is a right-angled trapezoidal groove. The protruding side of the first claw 1302 contacts and engages with the inclined side of the right-angled trapezoidal groove. By turning the second handle 1307, the second screw 1306 is driven to move the second movable plate 1308 toward the L-shaped base 1301. Then, the second spring 1310 squeezes the claw arm 1304, thereby clamping and fixing the first claw 1302 and the second claw 1305 to the outer wall of the support rod 15.

[0039] In use, the device connects one end of the force sensor 1 to the support rod 15 via a bow-shaped shackle 2 and a steel wire rope 4 (the support rod is equipped with a special connector for the steel wire rope). The other end of the force sensor 1 is connected to one end of a chain hoist 5 via a bow-shaped shackle 3. The other end of the chain hoist 5 is connected to a pipe via a steel wire rope 6. The output of the force sensor 1 is electrically connected to the input of a signal amplifier 7, the output of the signal amplifier 7 is electrically connected to the input of a digital-to-analog converter module 8, and the output of the digital-to-analog converter module 8 is electrically connected to a WIFI module 9. The WIFI module 9 transmits data to a handheld terminal. Next, the laser sensor 10 is fixedly mounted on the steel plate 14 on the upper part of the support rod via a laser sensor bracket 11. The self-balancing reflector 12 is fixedly mounted on the support rod 15 via a clamping device 13. The laser sensor 10 first measures its distance to the reflector 12. The distance of 01 is used as the standard distance and recorded on the handheld terminal. The extension rod at the lower part of the support rod 15 is removed from the lifting load on which the pipe is hoisted. At this time, the pipe is supported by the other supports, and the pipe will move slightly downward and sway. Then, the laser sensor 10 continuously measures the distance from it to the reflector 1201 and displays it on the handheld terminal. The gyroscope 1207 measures the angular deviation of the rod 15 relative to the initial position and corrects the measured distance of the laser sensor 10 in real time on the handheld terminal. The operator pulls the chain hoist 5 to move the pipe upward so that the measured distance of the laser sensor 10 after correction is the same as the standard distance. At this time, the tension measured by the force sensor 1 is read on the handheld terminal and compared with the rated output tension marked on the support nameplate. The error is calculated and compared with the allowable error range marked on the nameplate to know the performance of the support.

[0040] like Figure 10 As shown, distance correction using a handheld terminal requires gyroscope data to calculate the angle 'a' of the boom's tilt. The sway angle 'b' can then be obtained using the formula b = a. Therefore, the relationship between the actual distance and the measured distance is:

[0041] Actual distance = Measured distance / cos b.

[0042] Compared with the current measurement technology of strain gauges, the test process disclosed in this paper does not require complex auxiliary loading and unloading work, the process is simple, the workload is small, it is easy to use, does not require complicated operation, and has low operating cost. It is suitable for large-scale and rapid testing in the field.

[0043] Based on the hardware disclosed herein, the hardware system can be simplified, such as by eliminating the WiFi module and software system, and directly displaying the tensile force measured by the force sensor or laser sensor using an instrument or other device, and directly reading the data manually for detection.

[0044] The laser sensor component was removed, and alternative testing distance methods were used to detect the position of the load on the support frame, such as manual or other measurement methods.

[0045] Replace the chain hoist that connects the force sensor and the lifting load with other equipment.
