Description

Technical Field

[0001] This invention relates to the field of building steel structure monitoring devices, and in particular to an adjustable device for a monitoring data acquisition box. Background Technology

[0002] During service, steel structures inevitably suffer cumulative damage due to the combined effects of loads, environmental corrosion, material aging, and fatigue failure, leading to a decrease in structural resistance and increasing the risk of accidents. Steel structure health monitoring can promptly detect abnormal conditions, reducing or preventing economic losses and adverse social impacts caused by structural health problems. Health monitoring systems primarily use data acquisition boxes to collect data and transmit signals. Current technology involves directly welding the data acquisition box to the steel structure (steel pipe). However, welding the data acquisition box to the steel structure directly damages the material properties of the steel, affecting its service life. Furthermore, steel structure health monitoring requires monitoring different locations within the structure. If monitoring is needed at higher locations, the heavy data acquisition box must be manually moved to the upper part of the structure for installation, which is time-consuming, labor-intensive, and poses a risk to personal safety. Summary of the Invention

[0014] Furthermore, a clamping mechanism is fixedly installed at the top of the angle adjustment mechanism. The clamping mechanism includes a vertical clamping assembly for vertical adjustment and a horizontal clamping assembly for horizontal adjustment. Both the vertical and horizontal clamping assemblies are in two sets and symmetrically distributed around the center of the support plate. The vertical clamping assembly includes a fixed cylinder, a first threaded post, a first gear, a second gear, a third motor, a first chain, and a second chain. A fixed cylinder is fixedly installed near the end of the support plate. Multiple fixed cylinders are present and perpendicular to the support plate. A first threaded post is threaded into the fixed cylinder. A first gear is fixedly installed at the end of the first threaded post away from the fixed cylinder. Multiple first gears in the same set of vertical clamping assemblies are connected by a first chain.

[0015] Preferably, the first motor, the second motor, the third motor and the fourth motor are all DC geared motors.

[0016] The working principle of this invention is as follows: (1) Wrap a buffer pad made of polyurethane foam around the position where the rotating mechanism needs to be installed on the steel pipe, and then clamp two clamping plates onto the steel pipe wrapped with the buffer pad. Lock the two clamping plates onto the steel pipe with bolts and nuts. Fix the bracket to the base plate with bolts and nuts to achieve the fixed installation of the height adjustment mechanism. Install the angle adjustment mechanism on the base plate of the height adjustment mechanism. Install the clamping mechanism on the support plate of the angle adjustment mechanism. (2) First, place the monitoring data acquisition box on the support plate of the angle adjustment mechanism. Then, turn on the power. The horizontal clamping component and the vertical clamping component of the clamping mechanism start working respectively. The fourth motor of each of the two sets of horizontal clamping components drives the first motor. The three gears rotate in the forward direction, driving the third chain to cause the third gears on other mounting plates to rotate in the forward direction as well. The third gears drive the second threaded posts to rotate in the forward direction, causing the second threaded posts of both sets of lateral clamping assemblies to rotate in the forward direction on the mounting plates. The clamping blocks on the second threaded posts of the two sets of lateral clamping assemblies move closer together to clamp and fix the monitoring data acquisition box in the length direction. Similarly, the fourth motors of both sets of lateral clamping assemblies drive the third gears to rotate in the reverse direction, thus releasing the monitoring data acquisition box. The third motor of the vertical clamping mechanism drives the second gear to rotate in the forward direction. The forward rotation of the second gear in one set of vertical clamping mechanisms drives the second gear of the other set of vertical clamping mechanisms to rotate synchronously in the forward direction via the second chain. The forward rotation of the second gear drives the third... One gear rotates synchronously in the forward direction. The first gear rotates in the forward direction and drives the other first gears to rotate in the forward direction through the first chain. The first gear drives the first threaded column to rotate in the forward direction. The first threaded columns of the two sets of vertical clamping components rotate in the forward direction on the fixed cylinder. The first threaded columns of the two sets of vertical clamping components rotate in the forward direction and drive the mounting plate on it to descend in the height direction of the monitoring data acquisition box. The mounting plate drives the clamping block to move downward to clamp and fix the monitoring data acquisition box in the height direction. Similarly, the fourth motor of the vertical clamping component drives the second gear to rotate in the reverse direction, which can realize the release of the monitoring data acquisition box. The above operations complete the fixed installation of the monitoring data acquisition box on the support plate; (3) When it is necessary to adjust the position of the monitoring data acquisition box in the circumferential direction of the steel pipe. When, rotate the adjusting screw to separate it from the clamp plate, and then the arc plate can be freely rotated by the cooperation of the sliding plate and the sliding groove to achieve the purpose of adjusting the monitoring data acquisition box to any position in the circumference of the steel pipe. Then rotate the adjusting screw to make it contact the clamp plate, and fix the relative position of the arc plate and the clamp plate by friction. (4) When it is necessary to adjust the position of the monitoring data acquisition box in the height direction of the steel pipe, turn on the power of the first motor. The output shaft of the first motor rotates in the positive direction to drive the screw to rotate in the positive direction. The screw rotates in the positive direction to drive the seat plate to move upward along the height direction of the steel pipe. Similarly, the first motor drives the screw to rotate in the opposite direction to achieve the position adjustment of the monitoring data acquisition box in the height direction of the steel pipe.(5) When it is necessary to adjust the monitoring data acquisition box to be parallel to the horizontal plane, turn on the power of the second motor. The output shaft of the second motor rotates in the forward direction, causing the rotating shaft to rotate in the forward direction. The rotation of the rotating shaft causes an angle between the support plate and the base plate. Observe that when the monitoring data acquisition box is parallel to the horizontal plane, the second motor stops working. Then, the fixing buckle is put on the outside of the toothed plate to achieve a fixed engagement between the fixing buckle and the toothed plate. Then, the through hole of the fixing piece on the fixing buckle engages with the limiting post on the base plate to ensure that the support plate and the base plate are fixed at this angle, thus adjusting the monitoring data acquisition box to be parallel to the horizontal plane. Similarly, the output shaft of the second motor rotates in the reverse direction, causing the rotating shaft to rotate in the reverse direction. The reverse rotation of the rotating shaft causes the support plate to move closer to the base plate, reducing the angle between the support plate and the base plate.

[0017] The beneficial effects of the present invention are as follows: (1) The rotating mechanism of the present invention is detachably fixed to the steel pipe, which does not damage the steel pipe during installation or disassembly, ensuring the service life of the steel pipe and avoiding damage to the material properties of the steel pipe and shortening the service life of the steel pipe by welding fixed connection; (2) The sliding groove and sliding plate of the rotating mechanism cooperate to realize that the monitoring data acquisition box can rotate 360° around the axis of the steel pipe, and the monitoring data acquisition box can be fixed at any position in the circumference of the steel pipe by adjusting the screw, which facilitates the operation of the monitoring data acquisition box; (3) The connecting frame is set to create a gap between the arc plate and the base plate, so that the height adjustment mechanism does not collide with the clamp plate or the steel pipe during rotation, ensuring the smoothness of the height adjustment mechanism during rotation; (4) The first motor of the height adjustment mechanism drives the base plate to rise and fall along the height direction of the steel pipe, automatically and accurately monitoring The data acquisition box is sent to the target height for fixed use, which saves time and effort and does not pose a risk to personal safety; (5) The second motor of the angle adjustment mechanism drives the support plate to rotate from 0 to 90° relative to the base plate, so that the monitoring data acquisition box on the support plate is kept parallel to the horizontal plane, avoiding the monitoring data acquisition box from slipping during use. At the same time, when installing or maintaining the monitoring data acquisition box, it is more convenient to install and wire the monitoring data acquisition box in a horizontal state, and it is also convenient to open and maintain it; (6) The vertical clamping component of the clamping mechanism can meet the vertical clamping and fixing of monitoring data acquisition boxes of different heights, and the horizontal clamping component can meet the horizontal clamping and fixing of monitoring data acquisition boxes of different lengths; (7) Most of the components of this adjustable device are fixedly connected by bolts, which is convenient to operate during construction and debugging and can be reused.

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] like Figure 1 As shown, this invention provides an adjustable device for a monitoring data acquisition box, including a rotating mechanism 1 and a height adjustment mechanism 2 fixedly mounted on one side of the rotating mechanism 1. The rotating mechanism 1 is fixedly mounted on a steel pipe 6, and the monitoring data acquisition box 5 can be fixedly mounted on the height adjustment mechanism 2 by bolts. The rotating mechanism 1 can drive the monitoring data acquisition box 5 to rotate 360° around the steel pipe 6, and the height adjustment mechanism 2 can change the position of the monitoring data acquisition box 5 in the height direction of the steel pipe 6. The monitoring data acquisition box 5 is an automated data acquisition instrument, a distributed network automated data acquisition system, used in conjunction with independently developed monitoring cloud software. The sensor subsystem mainly consists of sensing elements capable of sensing four types of physical quantities: environmental and load effects, structural response, structural geometric deformation, and structural durability. Based on the principles of structural mechanics, the elements are optimized for deployment to achieve comprehensive perception of the overall and local performance of the structure. The data acquisition subsystem acquires various physical quantities to be sensed in real-time, timed, triggered, or mixed modes. It requires simultaneous control, synchronous acquisition, and high-speed demodulation of various types of sensor signals to achieve high-quality acquisition of monitoring data. The data transmission subsystem transmits the collected data to the data storage and management subsystem via wired or wireless means. The data storage and management subsystem provides functions for storing, querying, retrieving, and performing simple statistical analysis on monitoring data and structural information. The structural early warning and assessment subsystem performs mechanical analysis on the preprocessed data, including model correction, modal identification, damage diagnosis, condition assessment, life prediction, and maintenance decision-making.

[0043] like Figure 2 , Figure 3 and Figure 4 As shown, based on the above embodiment, the rotating mechanism 1 further includes a clamping plate 11, an arc-shaped plate 13, a base plate 14, and a connecting frame 15. Two clamping plates 11 are arranged as a group, and the clamping plates 11 are approximately semi-circular in shape. Ear plates 111 are fixedly provided on both sides of the clamping plate 11 near the corners. The clamping plate 11 and the ear plates 111 can be fixedly connected by welding, and the ear plates 111 are provided with through holes. A sliding groove 112 is machined at the center of the outer side of the clamping plate 11, and the cross-section of the sliding groove 112 is T-shaped. A sliding piece 131 is machined at the corresponding position of the arc-shaped plate 13. The cross-section of the sliding piece 131 is rectangular, and the sliding piece 131 slides in conjunction with the sliding groove 112. Adjusting screws 16 are provided near the sides of the arc-shaped plate 13, and the adjusting screws 16 are threadedly connected to the arc-shaped plate 13. Rotating the adjusting screw 16, when the end of the adjusting screw 16 abuts against the outer surface of the clamp plate 11, frictional force can achieve relative locking and fixation between the arc plate 13 and the clamp plate 11. A base plate 14 is installed on the side of the arc plate 13 away from the clamp plate 11, and the base plate 14 and the arc plate 13 are fixedly connected by a connecting frame 15. The connecting frame 15 is approximately a W-shaped truss structure, which creates a gap between the arc plate 13 and the base plate 14, so that the height adjustment mechanism 2 does not collide with the clamp plate 11 or the steel pipe 6 during rotation, ensuring the smoothness of the height adjustment mechanism 2 during rotation.

[0044] like Figure 2 , Figure 4 and Figure 12 As shown, based on the above embodiment, a buffer pad 12 is further provided on the inner side of the clamping plate 11. The buffer pad 12 is made of polyurethane foam and can prevent the steel pipe 6 from being squeezed and damaged by the rotating mechanism 1, thus protecting its material properties.

[0045] like Figure 3 , Figure 5 and Figure 10As shown, based on the above embodiment, the height adjustment mechanism 2 further includes a bracket 21, a seat plate 22, a lead screw 23, a mounting base 26, and a first motor 27. The bracket 21 is a steel truss. The side of the bracket 21 near the bottom is fixedly connected to the base plate 14 by bolts. The mounting base 26 is fixedly installed at the center of the side of the bracket 21 away from the base plate 14 by bolts. A lower limit plate 25 is fixedly installed on the bracket 21 above the mounting base 26, and an upper limit plate 28 is fixedly installed on the bracket 21 near the top. The lead screw 23 passes through the upper limit plate 28 and the lower limit plate 25. The first motor 27 is fixedly installed at the bottom of the mounting base 26, and the output shaft of the first motor 27 is fixedly connected to the lead screw 23 by a coupling. The lead screw 23 can be a ball screw 23, with a nut threaded onto it. A connecting block 24 is fixedly fitted on the outside of the nut, and one side of the connecting block 24 is fixedly connected to the side of the seat plate 22, thus mounting the seat plate 22 onto the lead screw 23. The seat plate 22 is L-shaped.

[0046] like Figure 3 and Figure 5 As shown, based on the above embodiment, a slide rail 211 is further fixedly installed on the side of the bracket 21 near the seat plate 22. The slide rail 211 and the bracket 21 can be fixedly connected by bolts. There are two slide rails 211, which are distributed in parallel and along the height direction of the bracket 21. A slider 221 is fixedly installed at a corresponding position on the seat plate 22, and the slider 221 slides in cooperation with the slide rail 211. The cross-section of the slide rail 211 is T-shaped, and the cross-section of the slider 221 is approximately a rectangular ring with a notch. The design of the cooperation scheme between the slide rail 211 on the bracket 21 and the slider 221 on the seat plate 22 makes the seat plate 22 more stable during the rising or falling process.

[0047] like Figure 5 and Figure 6As shown, based on the above embodiment, there are further two brackets 21. One bracket 21 has a protrusion 212 at one end, and the other bracket 21 has a groove 213 at the corresponding end. The protrusion 212 at the end of one bracket 21 mates with the groove 213 at the end of the other bracket 21. A through hole is machined on the protrusion 212, and a through hole is machined at a corresponding position on the groove 213. The protrusion 212 and the groove 213 are fixedly connected by bolts and nuts. The bracket 21 can be a steel truss structure. The height of one bracket 21 is 1 meter. Two brackets 21, each 1 meter high, are assembled to form a bracket 21 with a total height of 2 meters. The advantage of this design is that it facilitates installation or disassembly by the monitor at a normal height, and also facilitates the transport of the brackets 21, increasing the convenience of using the device. During installation, first, the protrusion 212 of one bracket 21 mates with the groove 213 of the other bracket 21. Then, bolts are passed through the through holes on the protrusion 212 and the groove 213 and engaged with nuts to fix the two brackets 21 together. The engagement of the protrusion 212 and the groove 213 makes the connection between the two fixedly installed brackets 21 more stable and secure.

[0048] like Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, based on the above embodiment, an angle adjustment mechanism 3 is further fixedly installed on the height adjustment mechanism 2. The angle adjustment mechanism 3 includes a support plate 31, a rotating shaft 32, a toothed plate 322, a fixing buckle 34, and a second motor 33. The bottom of the support plate 31 is attached to the top of the seat plate 22. The rotating shaft 32 passes through the support plate 31 near one end, and the two can be fixedly connected by welding or keying. One end of the rotating shaft 32 is rotatably connected to the side of the seat plate 22 through a bearing 321, and the other end of the rotating shaft 32 is fixedly connected to the output shaft of the second motor 33. The toothed plate 322 is fixedly installed on the rotating shaft 32 between the support plate 31 and the second motor 33. The toothed plate 322 is annular, and the outer surface of the toothed plate 322 is evenly distributed with teeth. The fixing buckle 34 is sleeved on the rotating shaft 32 between the support plate 31 and the second motor 33. The fixing buckle 34 has evenly distributed teeth on its inner cavity, and the fixing buckle 34 engages with the toothed plate 322. The base plate 22 is fixedly mounted with limit posts 222 by welding on both sides of the toothed plate 322. A fixing plate 35 is fixedly installed at the bottom of the fixing buckle 34. Through holes 351 are machined near the sides of the fixing plate 35, and these through holes 351 cooperate with the limit posts 222. A limit groove 223 is machined on the base plate 22 below the toothed plate 322. A limit block 36 is fixedly mounted at the bottom of the fixing plate 35. The limit block 36 slides within the limit groove 223. The cooperation between the limit block 36 and the limit groove 223 makes the fixing buckle 34 more stable when moving along the central axis of the rotating shaft 32. A monitoring data acquisition box 5 is fixedly placed on the support plate 31. The angle adjustment mechanism 3 rotates to keep the monitoring data acquisition box 5 parallel to the horizontal plane.

[0049] like Figure 7 , Figure 10 and Figure 11 As shown, based on the above embodiment, further, first protrusions 311 are uniformly arranged on the support plate 31, and multiple first protrusions 311 are distributed parallel to each other along the width direction of the support plate 31; second protrusions 51 are uniformly arranged on the bottom of the monitoring data acquisition box 5, and the second protrusions 51 cooperate with the first protrusions 311. When the monitoring data acquisition box 5 is placed on the support plate 31, the first protrusions 311 on the support plate 31 cooperate with the second protrusions 51 on the bottom of the monitoring data acquisition box 5 to prevent the monitoring data acquisition box 5 from sliding in the length direction. Through grooves 312 are machined on the support plate 31 between the first protrusions 311, and through grooves 312 are machined on the seat plate 22 at corresponding positions to the support plate 31. The through slot 312 can reduce the weight of the support plate 31 and the base plate 22, making it easier to select a motor with lower power. In addition, the monitoring data acquisition box 5 (automatic data acquisition instrument) needs to install many wires to connect to the outside world for monitoring data and transmitting information to the computer. The through slot 312 has the advantage of placing the wires corresponding to each connection hole in the corresponding through slot 312, making the wires less likely to get tangled and making it easier to identify each wire.

[0050] like Figure 1 and Figure 15 As shown, based on the above embodiment, the angle at which the support plate 31 can rotate relative to the base plate 22 is further 0 to 90°. The function of the angle adjustment mechanism 3 is to ensure that the monitoring data acquisition box 5 is more convenient and has better visibility when performing operations such as connecting wires and power cords; and to make it easier to open the monitoring data acquisition box 5 in a horizontal state during the later periodic inspection and maintenance of the monitoring data acquisition box 5, and also to facilitate maintenance.

[0051] like Figure 12 , Figure 13 and Figure 14As shown, based on the above embodiment, a clamping mechanism 4 is further fixedly installed on the top of the angle adjustment mechanism 3. The clamping mechanism 4 includes a vertical clamping assembly 41 for vertical adjustment and a horizontal clamping assembly 42 for horizontal adjustment. Both the vertical clamping assembly 41 and the horizontal clamping assembly 42 have two sets and are symmetrically distributed with the middle of the support plate 31 as the center of symmetry. The vertical clamping assembly 41 includes a fixed cylinder 411, a first threaded post 412, a first gear 413, a second gear 414, a third motor 415, a first chain 416, and a second chain 417. A fixed cylinder 411 is fixedly installed near the end of the support plate 31. There are multiple fixed cylinders 411, all perpendicular to the support plate 31. The fixed cylinders 411 and the support plate 31 can be fixedly connected by welding or bolts. The first threaded post 412 is threadedly connected inside the fixed cylinder 411. The first threaded post 412 rotates within the fixed cylinder 411 to achieve upward or downward movement in the height direction. A first gear 413 is fixedly installed on the end of the first threaded post 412 away from the fixed cylinder 411 by welding. Multiple first gears 413 of the same set of vertical clamping assemblies 41 are connected by a first chain 416. A connecting post is fixedly installed on the end of one first gear 413 of each of the two sets of vertical clamping assemblies away from the first threaded post 412. A second gear 414 is fixedly installed on the end of the connecting post away from the first gear 413. The second gears 414 of the two sets of vertical clamping assemblies 41 are connected by a second chain 417. The end of one second gear 414 of any set of vertical clamping assemblies 41 away from the connecting post is fixedly connected to the output shaft of a third motor 415. The second chain 417 drives the first gears 413 of the two sets of vertical clamping assemblies 41 to rotate synchronously at the same height. Based on the height of the monitoring data acquisition box 5, the synchronous lifting and lowering of the two sets of vertical clamping assemblies 41 is precisely adjusted to the same height. The transverse clamping assembly 42 includes a mounting plate 421, a second threaded post 422, a third gear 423, a fourth motor 424, and a third chain 425. A bearing 321 is fixedly mounted on the first threaded post 412 near the first gear 413, and the mounting plate 421 is fixedly sleeved on the outside of the bearing 321. The second threaded posts 422 are threadedly mounted on both ends of the mounting plate 421, and the second threaded posts 422 are spatially perpendicular to the first threaded posts 412. A clamping block 43 is provided at one end of the second threaded post 422 near the center of the support plate 31, and the clamping block 43 is rotatably connected to the second threaded post 422 via the bearing 321. The clamping block 43 is L-shaped. A third gear 423 is fixedly installed at one end of the second threaded post 422 away from the center of the support plate 31. Multiple third gears 423 of the same set of transverse clamping assemblies 42 are connected by a third chain 425. One end of a third gear 423 of the two sets of transverse clamping assemblies 42 away from the second threaded post 422 is fixedly connected to the output shaft of the fourth motor 424.The vertical clamping component 41 of the clamping mechanism 4 can satisfy the vertical clamping and fixing of monitoring data acquisition boxes 5 of different heights, and the horizontal clamping component 42 can satisfy the horizontal clamping and fixing of monitoring data acquisition boxes 5 of different lengths. Therefore, this adjustable device can place monitoring data acquisition boxes 5 of different types and sizes according to monitoring needs, and the clamping mechanism 4 can clamp and fix them.

[0052] Preferably, the first motor 27, the second motor 33, the third motor 415, and the fourth motor 424 are all DC geared motors. Specifically, the first motor 27 can be a DC geared motor with a speed of 10 rpm, a power of 50 W, a voltage of 24 V, and a maximum torque of 229 kg·cm; the second motor 33, the third motor 415, and the fourth motor 424 can be DC geared motors with a speed of 10–100 rpm and a power of 20–50 W.

[0053] The working process of this invention is as follows: Figure 1 , Figure 4 and Figure 12 As shown, (1) a layer of buffer pad 12 made of polyurethane foam is wrapped around the position where the rotating mechanism 1 needs to be installed on the steel pipe 6, and then two clamping plates 11 are clamped onto the steel pipe 6 wrapped with buffer pad 12. The two clamping plates 11 are locked and fixed on the steel pipe 6 by bolts and nuts; the bracket 21 is fixedly installed on the base plate 14 by bolts and nuts to realize the fixed installation of the height adjustment mechanism 2; the angle adjustment mechanism 3 is installed on the seat plate 22 of the height adjustment mechanism 2; the clamping mechanism 4 is installed on the support plate 31 of the angle adjustment mechanism 3; as Figure 12 , Figure 13 and Figure 14As shown, (2) First, place the monitoring data acquisition box 5 on the support plate 31 of the angle adjustment mechanism 3. Then, turn on the power, and the horizontal clamping assembly 42 and the vertical clamping assembly 41 of the clamping mechanism 4 start working respectively. The fourth motor 424 of the two sets of horizontal clamping assemblies 42 drives the third gear 423 to rotate in the forward direction. Through the drive of the third chain 425, the third gear 423 on the other mounting plates 421 starts to rotate in the forward direction. The third gear 423 drives the second threaded column 422 to rotate in the forward direction. The second threaded posts 422 of both sets of transverse clamping assemblies 42 rotate forward on the mounting plate 421. The clamping blocks 43 on the second threaded posts 422 of the two sets of transverse clamping assemblies 42 approach each other to clamp and fix the monitoring data acquisition box 5 in the length direction. Similarly, the fourth motors 424 of both sets of transverse clamping assemblies 42 drive the third gears 423 to rotate in the opposite direction to release the monitoring data acquisition box 5. The third motor 415 of the vertical clamping mechanism 4 drives the second gear 414 to rotate forward, and a set of vertical clamping... The second gear 414 of mechanism 4 rotates forward, driving the second gear 414 of another set of vertical clamping mechanisms 4 to rotate synchronously forward via the second chain 417. The forward rotation of the second gear 414 drives the first gear 413 to rotate synchronously forward. The forward rotation of the first gear 413 drives the other first gears 413 to rotate forward via the first chain 416. The first gear 413 drives the first threaded column 412 to rotate forward. The first threaded columns 412 of both sets of vertical clamping components 41 rotate forward on the fixed cylinder 411. The forward rotation of the first threaded columns 412 of both sets of vertical clamping components 41 drives the mounting plate 421 on it to descend in the height direction of the monitoring data acquisition box 5. The mounting plate 421 drives the clamping block 43 to move downward to clamp and fix the monitoring data acquisition box 5 in the height direction. Similarly, the fourth motor 424 of the vertical clamping component 41 drives the second gear 414 to rotate in the opposite direction to release the monitoring data acquisition box 5. The above operations complete the fixed installation of the monitoring data acquisition box 5 on the support plate 31. Figure 2 , Figure 3 and Figure 4 As shown, (3) when it is necessary to adjust the position of the monitoring data acquisition box 5 around the steel pipe 6, rotate the adjusting screw 16 to separate it from the clamp plate 11, and then the arc plate 13 can be freely rotated by the cooperation of the sliding plate 131 and the sliding groove 112 to achieve the purpose of adjusting the monitoring data acquisition box 5 to any position around the steel pipe 6. Then rotate the adjusting screw 16 to make it contact the clamp plate 11, and fix the relative position of the arc plate 13 and the clamp plate 11 by friction. Figure 3 , Figure 5 and Figure 10As shown, (4) when it is necessary to adjust the position of the monitoring data acquisition box 5 in the height direction of the steel pipe 6, the power supply of the first motor 27 is turned on. The output shaft of the first motor 27 rotates in the forward direction, driving the lead screw 23 to rotate in the forward direction. The forward rotation of the lead screw 23 drives the seat plate 22 to move upward along the height direction of the steel pipe 6. Similarly, the first motor 27 drives the lead screw 23 to rotate in the reverse direction, which can realize the seat plate 22 moving downward along the height direction of the steel pipe 6, thereby achieving the position adjustment of the monitoring data acquisition box 5 in the height direction of the steel pipe 6; Figure 7 , Figure 8 , Figure 9 and Figure 15 As shown, (5) when it is necessary to adjust the monitoring data acquisition box 5 to be parallel with the horizontal plane, the power supply of the second motor 33 is turned on. The output shaft of the second motor 33 rotates in the forward direction, driving the rotating shaft 32 to rotate in the forward direction. The rotation of the rotating shaft 32 in the forward direction makes the support plate 31 and the seat plate 22 have an angle. By observation, when the monitoring data acquisition box 5 is parallel with the horizontal plane, the second motor 33 stops working. Then, the fixing buckle 34 is put on the outside of the toothed plate 322 to realize the fixing buckle 34 and the toothed plate 322 fixedly cooperate. Then, the through hole 351 of the fixing piece 35 on the fixing buckle 34 cooperates with the limiting post 222 on the seat plate 22 to ensure that the support plate 31 and the seat plate 22 are fixed in this angle state, so as to realize the adjustment of the monitoring data acquisition box 5 to be parallel with the horizontal plane. Similarly, the output shaft of the second motor 33 rotates in the reverse direction, driving the rotating shaft 32 to rotate in the reverse direction. The rotation of the rotating shaft 32 in the reverse direction makes the support plate 31 move closer to the seat plate 22, reducing the angle between the support plate 31 and the seat plate 22. Figure 15 As shown, some steel pipes in the building structure are installed vertically. In this case, the monitoring data acquisition box 5 is parallel to the horizontal plane and does not need to be adjusted by the angle adjustment mechanism 3. However, some steel pipes are installed at an angle. In this case, the monitoring data acquisition box 5 has an angle with the horizontal plane and needs to be adjusted by the angle adjustment mechanism 3 to ensure that the monitoring data acquisition box 5 is parallel to the horizontal plane.
