DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 2 、 Figure 3 and Figure 5 , an embodiment provided by the present invention: A leg stress monitor for a jack-up platform, including a workbench 1, a mounting frame 2 is fixedly connected to the bottom of the workbench 1, a chute 3 is opened at the bottom of the mounting frame 2, a monitor body 4 is slidably connected inside the chute 3, two mounting blocks 5 are fixedly connected to the front side of the monitor body 4, outer shells 6 are fixedly connected to both the left and right sides of the mounting frame 2, connectors 7 are arranged inside both outer shells 6, springs 8 are fixedly connected to one end of both connectors 7, one end of both springs 8 is fixedly connected to the opposite sides of the outer shells 6, bolts 9 are fixedly connected inside both connectors 7, screw holes 10 are opened at the opposite sides of both mounting blocks 5, a connecting plate 20 is fixedly connected to the bottom of the workbench 1, a telescopic rod 21 is fixedly connected to the front side of the connecting plate 20, the outer wall of the telescopic rod 21 is slidably connected inside the mounting frame 2, a plurality of stress sensing sheets 14 are installed on the outer wall of the lifting column 12, one end of each of the plurality of stress sensing sheets 14 is fixedly connected to a transmission wire 15, a Type-C connection port 16 and an HDMI connection port 17 are arranged on the right side of the monitor body 4, one end of the transmission wire 15 is installed inside the Type-C connection port 16, an alarm mechanism 11 is arranged on the front side of the workbench 1, and the alarm mechanism 11 is used to give an alarm when the stress undergoes an uncontrollable change;

[0033] Specifically, when the stress monitor body 4 needs to be disassembled under specific circumstances, first pull out the transmission wire 15 and pull the bolt 9 outward. At this time, it can be seen that one end of the spring 8 is firmly fixed on the outer shell 6, while the other end is firmly fixed on the connecting piece 7. As the bolt 9 continues to move, the connecting piece 7 moves inside the outer shell 6, and the spring 8 gradually undergoes elastic deformation and is continuously stretched. The bolt 9 continues to move outward until it completely leaves the screw hole 10. At this time, immediately activate the telescopic rod 21. The model of the telescopic rod 21 is DGT-100. The telescopic rod 21 quickly extends forward. Under its pushing action, the monitor body 4 starts to slide smoothly on the chute 3. As the telescopic rod 21 continues to extend, the monitor body 4 continues to slide forward until it completely slides out of the installation frame 2. Loosen the bolt 9, and the spring 8 will quickly recover its elastic deformation and return to the initial state. This design enables the installation frame 2 to quickly disassemble the monitor body 4 and, when needed, can put the monitor body 4 into the installation frame 2 again, greatly simplifying the installation steps of the monitor. This convenient operation method greatly improves the use efficiency of the stress monitor and brings great convenience to the pile leg stress monitoring work of the jack-up platform.

[0034] Refer to Figure 1 、 Figure 2 and Figure 4 , the alarm mechanism 11 includes a rectangular block 1101. The rear side of the rectangular block 1101 is fixedly connected to the front side of the workbench 1. A groove 1102 is formed on the front side of the rectangular block 1101. A servo motor 1103 is fixedly connected inside the groove 1102. The output end of the servo motor 1103 is fixedly connected to a turntable 1104. A reflecting mirror 1105 is fixedly connected to the outer wall of the turntable 1104. An alarm lamp 1106 is fixedly connected to the front side of the rectangular block 1101;

[0035] Specifically, once an uncontrollable and drastic change in stress occurs, the stress sensor 14 installed at a critical position will immediately transmit an accurate stress change signal to the monitor body 4 through the transmission wire 15. The monitor body 4 has powerful analysis and processing capabilities and will deeply analyze the signal instantly upon receiving it. If it is determined that the stress change exceeds the safe range, the monitor body 4 will quickly transmit an alarm signal to the control panel 24, and the control panel 24 will precisely control the servo motor 1103 to start upon receiving the alarm signal. At the same time, the prominent alarm light 1106 will turn on the flashing mode and emit a strong warning signal. At this time, the servo motor 1103 will drive the turntable 1104 to rotate steadily and powerfully, and the mirror 1105 installed on the turntable 1104 will rotate along with the rotation of the turntable 1104. During the rotation process, the mirror 1105 can skillfully reflect and refract the strong light emitted by the alarm light 1106, and these reflected and refracted lights will spread out at a wider angle and range, thereby effectively warning the staff at different positions. In this way, the problem of excessive stress change in the leg of the jack-up platform can be detected in time, precious time can be gained for subsequent emergency treatment, and the safe and stable operation of the platform can be guaranteed to the greatest extent.

[0036] Refer to Figure 1 and Figure 2 Specifically, lifting columns 12 are fixedly connected to the four corners of the bottom of the workbench 1. The bottoms of the multiple lifting columns 12 are fixedly connected with foot pads 13. A guard plate 22 and a partition plate 23 are fixedly connected to the top of the workbench 1. A control panel 24 is fixedly connected to the front side of the workbench 1. A knob 25 is installed on the front side of the control panel 24. A display screen 18 is fixedly connected to the front side of the monitor body 4, and a signal lamp 19 is fixedly connected to the front side of the monitor body 4.

[0037] Specifically, the lifting columns 12 can lift the workbench 1. The foot pads 13 can improve the stability of the lifting columns 12 and extend the service life of the lifting columns 12. The guard plate 22 and the partition plate 23 can plan the working space of the workbench 1 and improve the utilization efficiency of the space. The control panel 24 can receive signals to control the device. The knob 25 can be used for control and adjustment. The display screen 18 can display the stress condition in real time, and at the same time, the stress range can be displayed through the signal lamp 19, enabling the staff to clearly and intuitively understand what range the stress magnitude is in.

[0038] Working principle: When it is necessary to disassemble the stress monitor body 4, first pull the bolt 9 to move outward. One end of the spring 8 is fixed on the housing 6 and the other end is fixed on the connecting member 7. At this time, the spring 8 undergoes elastic deformation. The bolt 9 continues to move until the bolt 9 completely leaves the screw hole 10. At this time, start the telescopic rod 21, and the telescopic rod 21 extends forward, so that the monitor body 4 slides on the chute 3 until the monitor body 4 completely slides out of the installation frame 2. At this time, loosen the bolt 9, and the spring 8 restores elastic deformation, so that the installation frame 2 can quickly disassemble and reinstall the monitor body 4, simplifying the installation steps of the monitor and greatly improving the use efficiency;

[0039] And when the stress changes uncontrollably, the stress sensing piece 14 will transmit the stress change signal to the monitor body 4 through the transmission wire 15. The monitor body 4 will analyze the signal and transmit the alarm signal to the control panel 24. The control panel 24 will control the servo motor 1103 to start. At the same time, the alarm light 1106 will turn on the flashing mode. At this time, the servo motor 1103 drives the turntable 1104 to rotate, and the reflector 1105 on the turntable 1104 will rotate. The reflector 1105 will reflect and refract the light of the alarm light 1106, so as to warn the staff and make the problem of excessive stress change be discovered in time.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
