Description

Technical Field

[0001] This invention relates to the field of intelligent detection technology, and in particular to an intelligent detection system for unconventional hoisting behavior using a ground-mounted pole. Background Technology

[0002] To ensure safety during the hoisting of ground-mounted jib cranes, sensors need to be installed on the jib cranes to achieve real-time monitoring of their status. CN116853947A discloses a ground-mounted double-rocker jib crane torque monitoring system. An angle monitor installed on the rocker arm and the jib body monitors the horizontal tilt angle of the rocker arm, and a load monitor installed on the hook of the rocker arm monitors the load of the rocker arm. This allows for the calculation of unbalanced torque, enabling timely adjustments and control by personnel. CN217148347U discloses a ground-mounted double-rocker jib crane force measurement and monitoring system. This system monitors the tilt angle of the top of the main jib crane using a jib top tilt angle sensor installed at the top of the main jib crane; and measures the wind speed and direction at the construction site using an anemometer installed on the main jib crane. This allows for an objective understanding of whether the stress condition of the ground-mounted double-rocker jib crane exceeds the crane's design rated operating conditions, reducing the risk of jib crane breakage due to unbalanced torque exceeding design operating conditions on both sides. CN111931303B discloses a method, device, equipment, and storage medium for early warning of the stress state of a pole. Based on pre-set simulation information of the stress state of the pole, the installation position is determined, and an intelligent sensing standard section with multiple sensors is installed at the installation position to realize early warning of the stress state of the pole.

[0003] The aforementioned intelligent detection systems for ground-mounted poles all utilize tilt sensors to detect the status of the poles. However, since tilt sensors typically only trigger an alarm after the pole has tilted to a certain extent, they lack pre-warning capabilities. Furthermore, the sensor installation positions in existing intelligent detection systems lack standards, which can easily lead to data distortion and affect the detection effectiveness of the intelligent detection system.

[0004] Based on the above-mentioned technical problems, this application proposes an intelligent detection system for unconventional hoisting behavior of ground-mounted poles. Summary of the Invention

[0028] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0029] like Figures 1-7The system illustrates an intelligent detection system for unconventional hoisting behavior using a ground-mounted jib, comprising a weather sensor 1, a sensor assembly 2, a control module (not shown), and a ground-mounted jib 3. The ground-mounted jib 3 is a flat-arm type, comprising a main pole 31, a mast 32 mounted on the upper end of the main pole 31 via a turntable, and rocker arms 33 pivotally mounted at both ends of the mast 32. The main pole 31 is assembled from multiple standard sections. The weather sensor 1 is mounted on the top of the mast 32, and the sensor assembly 2 is mounted between two standard sections at the top of the main pole 31, with the sensor assembly 2 being lower than the height of the rocker arms 31. A movable frame 34 is slidably mounted on the rocker arms 33, and a hook 36 is mounted on the movable frame 34 via a hoisting rope 35. The other end of the hoisting rope 35 passes through the main pole 31 and connects downwards to a winch 37. The movable frame 34 can reciprocate along the rocker arms 33 to adjust the horizontal position of the hook 36; the winch 37 can adjust the vertical height of the hook 36 by winding and unwinding. The specific structure and principle of the flat-arm ground-mounted pole are existing technologies and will not be described in detail here.

[0030] like Figures 2-5 As shown, sensor assembly 2 includes an upper connector 21, connecting posts 22, a lower connector 23, and pressure sensors 24. Both the upper connector 21 and the lower connector 23 are rectangular frame structures. Four connecting posts 22 are installed between the upper connector 21 and the lower connector 23, and are symmetrically arranged at the four corners of the upper connector 21. Four pressure sensors 24 are symmetrically arranged at the four corners of the lower connector 23, and all four pressure sensors 24 abut against the upper connector 21. The meteorological sensor 1 and the four pressure sensors 24 are all communicatively connected to the control module. The control module monitors the tilt state, wind load, and rocker arm torque of the ground-mounted support pole 3 based on the wind speed and force measured by the meteorological sensor 1 and the pressure difference between the four pressure sensors 24.

[0031] By symmetrically installing four pressure sensors 24 at the four corners of the upper connector 21 and lower connector 23 of the rectangular structure, the installation positions of the four pressure sensors 24 can be rationally arranged in advance based on simulation results. This standardization of the installation positions of the pressure sensors 24 improves the detection accuracy of the sensors and ensures the normal operation of the intelligent detection system. Simultaneously, the modular structure facilitates the installation of the four pressure sensors, enhancing installation convenience. Furthermore, by directly measuring the force at each support point through the four pressure sensors, the structural stress of the ground-supported pole can be detected in real time and reliably, enabling real-time monitoring and early warning of the intelligent detection system.

[0032] like Figure 5As shown, the upper connecting member 21 includes an upper connecting frame 211, which is a rectangular frame welded from steel profiles. First corner plates 212 are welded and fixed to the four corners of the upper surface of the upper connecting frame 211. The first corner plates 212 have through holes, and the upper connecting member 21 is fixedly connected to the lower end of the upper standard section through the first corner plates 212. First connecting plates 213 are welded and fixed to the four corners of the lower surface of the upper connecting frame 211. The first connecting plates 213 and first corner plates 212 are arranged opposite each other, and the upper end of the connecting column 22 is screwed and fixed to the first connecting plate 213. One end of the first connecting plate 213 extends outward to form a first boss 214, which protrudes from the upper connecting frame 211. An adjusting member 215 is installed on the first boss 211. The adjusting member 215 is a screw rod, which is vertically installed on the first boss 211. The four corners of the upper connecting frame 211 are respectively welded and fixed with first reinforcing plates 216. Two first reinforcing ribs 217 are welded and fixed between the first reinforcing plates 216 and the first connecting plate 213 to enhance the structural strength of the first connecting plate 213 and reduce its deformation.

[0033] like Figure 4 As shown, the lower connecting member 23 includes a lower connecting frame 231, which is a rectangular frame welded from structural steel. Second corner plates 232 are welded and fixed to the four corners of the lower end face of the lower connecting frame 231. Through holes are provided on the second corner plates 232, and the lower connecting member 23 is fixedly connected to the upper end of the lower standard section through the second corner plates 232. Second connecting plates 233 are welded and fixed to the four corners of the upper end face of the lower connecting frame 231. The second connecting plates 233 and second corner plates 232 are arranged opposite each other, and the lower end of the connecting column 22 is fixedly connected to the second connecting plate 233. One end of the second connecting plate 233 extends outward to form a second boss 234, which protrudes from the lower connecting frame 231. The lower connecting frame 231 has a second reinforcing plate 235 welded and fixed at each of its four corners. A second reinforcing rib 236 is welded and fixed between the second reinforcing plate 235 and the second connecting plate 233. The second reinforcing rib 236 extends to the bottom of the second boss 234 to support the second boss 234.

[0034] like Figures 2-5 As shown, pressure sensors 24 are mounted on the second boss 234, and four pressure sensors 24 are located at the four corners of the same structural square, with the center of the inscribed circle of the structural square located on the vertical axis of the base rod 3. The adjusting member 215 abuts against the pressure sensor 24, and the vertical pressure of the pressure sensor 24 can be adjusted by adjusting the screw depth.

[0035] By mounting the pressure sensor 24 on the second boss 234 on one side of the connecting post 22 and connecting the pressure sensor 24 to the upper connector 21 by adjusting the screw, the pressure sensor 24 can be easily replaced, which facilitates the maintenance of the pressure sensor 24.

[0036] After the ground-mounted scaffold is installed, the verticality of the scaffold is first confirmed to meet the requirements using a total station. The pressure value of the pressure sensor 24 is then adjusted to 1 / 3 to 1 / 2 of the range of the pressure sensor 24 using the adjusting component 215, and the pressure values ​​of the four pressure sensors 24 are made equal, so that the pressure difference of the four pressure sensors 24 can be observed more intuitively.

[0037] Ground-mounted pole tilt detection

[0038] When a ground-mounted gantry tilts due to foundation settlement, the shift in its center of gravity alters the pressure readings on its four pressure sensors, increasing pressure on one side (or one corner) and decreasing pressure on the other side (or diagonally opposite). In calm or weak wind conditions, the tilt of the gantry in the X and Y directions can be calculated by determining the differences in pressure readings from the four sensors. When the pressure difference exceeds a certain threshold, the gantry is considered to be tilted.

[0039] Wind load detection

[0040] Wind loads acting on the ground-mounted pole generate horizontal forces and overturning moments, resulting in pressure differences among the four pressure sensors. For example, wind blowing from the +X direction will decrease the pressure on the +X side pressure sensor and increase the pressure on the -X side pressure sensor. By combining wind direction and force data measured by meteorological sensors with the pressure differences from the four pressure sensors, wind loads can be detected.

[0041] Rocker arm torque detection

[0042] When the rocker arm is working, if the loads on the two sides of the rocker arm are different or the moving frame moves out of different distances, different overturning moments will be generated at the root of the rocker arm. This will cause the ground-mounted support rod to tilt towards the side with the larger overturning moment, resulting in a pressure difference between the four pressure sensors. At this time, the pressure sensor on the side with the larger overturning moment will have increased pressure, while the pressure sensor on the side with the smaller overturning moment will have decreased pressure. The rocker arm torque can be detected by measuring the pressure difference between the four pressure sensors.

[0043] like Figure 2 , Figure 3 As shown, a storage battery (not shown) and a power generation component 4 are installed between the upper connector 21 and the lower connector 23. The storage battery is connected to the weather sensor 1 and four pressure sensors 24 through wires to supply power to the weather sensor 1 and the four pressure sensors 24.

[0044] like Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, the power generation assembly 4 includes a mounting base 41, on which a through-shaft 42 is fixed. The mounting base 41 is rotatably mounted between the upper connector 21 and the lower connector 23 via the shaft 42. A generator 43 is mounted on the left side of the front end face of the mounting base 41. A rotating wheel 44 is mounted on the rotating shaft of the generator 43. The generator 43 is electrically connected to the battery through a charge / discharge management circuit for charging the battery.

[0045] A connecting seat 45 is installed on the right side of the front end face of the mounting base 41. A through-hole is formed in the center of the connecting seat 45, and an adjusting screw 46 is screwed into the hole. Two guide holes are symmetrically formed on the upper and lower sides of the threaded hole. An adjusting seat 47 is installed on the left end of the connecting seat 45. The adjusting seat 47 is slidably connected to the connecting seat 45 via two guide rods 48, and the adjusting screw 46 abuts against the right end face of the adjusting seat 47. Two clamping rollers 49 are installed on the adjusting seat 47. The suspension rope 35 of the ground-mounted support 3 is clamped between the clamping rollers 49 and the rotating roller 44. By changing the screw depth of the adjusting screw 46, the distance between the clamping rollers 47 and the rotating roller 44 can be adjusted, thereby adjusting the clamping force of the suspension rope 35. When the ground-mounted support 3 is working, the suspension rope 35 moves up and down along the main rod 31, thereby driving the rotating roller 44 to rotate, which in turn drives the generator 43 to generate electricity, thus charging the battery.

[0046] Preferably, both the rotating wheel 44 and the clamping wheel 47 have circumferential limit grooves, and the lifting rope 35 is engaged in the limit grooves to prevent the lifting rope 35 from slipping out between the rotating wheel 44 and the clamping wheel 47. The limit grooves are provided with anti-slip textures to prevent the lifting rope 35 from slipping on the rotating wheel 44 and to ensure the power generation efficiency of the generator 43.

[0047] The technical solutions provided in this application have at least the following technical effects or advantages:

[0048] 1. By installing meteorological sensors and a sensor assembly with four pressure sensors on the ground-mounted derrick, it is possible to monitor multiple states of the ground-mounted derrick, including its tilt state, wind load, and rocker arm torque. This enables comprehensive monitoring of the ground-mounted derrick and improves the safety of ground-mounted derrick construction.

[0049] 2. By installing a battery and a power generation unit at the sensor assembly, the power generation unit is driven by the raising and lowering of the ground-mounted pole rope to generate electricity, thereby charging the battery, reducing the number of manual maintenance operations and lowering the workload of the operators;

[0050] 3. The generator assembly is rotatably mounted on the sensor assembly via a rotating shaft, which buffers the generator assembly and the suspension rope, preventing the impact of the suspension rope swaying on the generator assembly and extending the service life of the generator assembly;

[0051] 4. By mounting the clamping wheel on the movable adjusting seat, the gap between the clamping wheel and the rotating wheel can be adjusted to prevent the rotating wheel from slipping relative to the suspension rope and ensure the generator's power generation efficiency.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
