Description

Technical Field

[0001] This invention relates to the field of anchor beam and anchor bolt construction technology, specifically to a hoisting assembly and hoisting method for anchor beam and anchor bolt construction. Background Technology

[0002] When hoisting anchor beams and anchor rods, precise alignment is required at multiple angles and in multiple postures. However, anchor beams and anchor rods are characterized by their large weight and long dimensions, resulting in a high risk of slippage during hoisting. Traditional hoisting tools usually require separate designs for anchor beams and anchor rods to meet hoisting requirements.

[0003] For example, Chinese patent CN221796741U discloses a steel anchor beam lifting tool, which uses mechanical operation to adjust the length of the device and limit its fixation to adapt to the lifting of anchor beams of different lengths. Another example is Chinese patent CN217323011U, which discloses a special lifting tool for anchor bolts in a steel anchoring system. This tool uses a three-dimensional frame structure formed by upper and lower bases and multiple tie rods to position and lift the anchor bolts from the outside.

[0004] For the hoisting of anchor beams and anchor rods, separate hoisting tools need to be customized, making it difficult to make full use of the tools. Furthermore, the cross-sectional dimensions of anchor rods are smaller than those of anchor beams, and the installation distance between anchor rods is also smaller. If the hoisting tools used for hoisting anchor beams are directly used to fix anchor rods, the hoisting tools may be too large during installation, making proper installation impossible.

[0005] Based on this, the present invention designs a hoisting assembly and hoisting method for anchor beam and anchor rod construction to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hoisting assembly and hoisting method for anchor beam and anchor rod construction.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A hoisting assembly for anchor beam and anchor bolt construction includes a hoisting tool, a limiting structure, and a hoisting point unit. The hoisting tool includes a lower anti-slip seat, an upper anti-slip seat, at least four fixed threaded rods, an upper fixing nut, and a lower fixing nut. The four fixed threaded rods are arranged in a rectangular array on the lower and upper anti-slip seats, passing through the lower and upper anti-slip seats. The upper fixing nut is located on the upper side of the upper anti-slip seat and threadedly connected to the fixed threaded rods, and the lower fixing nut is located on the lower side of the lower anti-slip seat and threadedly connected to the fixed threaded rods. The distance between the fixed threaded rods on the same side is consistent with the bottom width of the anchor beam, and the distance between the fixed threaded rods on both sides is consistent with the bottom width of the anchor bolt. The hoisting point unit is installed on the upper anti-slip seat. The limiting structure is used to install on the connecting end of the anchor bolt and can be connected to the hoisting tool located on the anchor bolt near the connecting end.

[0009] Furthermore, the hoisting assembly for anchor beam and anchor bolt construction also includes a monitoring mechanism, which includes monitoring component one, monitoring component two, and an alarm component. Monitoring component one is installed on the anchor beam, and an alarm component is installed on monitoring component one; monitoring component two and an alarm component are installed on the limiting structure.

[0010] Furthermore, the lifting point unit includes fixed lifting points, an adjusting structure, lifting rings, and a lifting auxiliary plate. An adjusting structure is installed on one side of the upper anti-slip seat, and a set of fixed lifting points is installed on the adjusting structure. Another set of fixed lifting points is installed on the other side of the upper anti-slip seat. Each fixed lifting point is equipped with a lifting ring. The lifting auxiliary plate is detachably connected to the anchor beam. The construction crane is connected to the lifting rings via lifting ropes, and the auxiliary crane is connected to the lifting auxiliary plate via lifting ropes.

[0011] Furthermore, the limiting structure includes a limiting plate, an ear plate, a tie rod, and a locking nut. The limiting plate is fixedly installed on the connecting end of the anchor rod by bolts and nuts. An ear plate is fixedly installed on the limiting plate. An ear plate is fixedly installed on the upper anti-slip seat located at the lowest side of the anchor rod. After one end of the tie rod is threadedly connected to a set of locking nuts, the other end passes through the limiting plate and the ear plate on the upper anti-slip seat in sequence and is threadedly connected to another set of locking nuts.

[0012] Furthermore, the monitoring component two includes a pad and a pressure sensor two, with the pressure sensor two fixedly mounted on the ear plate of the limiting plate; the pad is disposed on the pull threaded rod and located between the pressure sensor two and the locking nut one.

[0013] Furthermore, the monitoring component includes an installation structure and a monitoring module. The installation structure is used to install on the anchor beam, and the monitoring module is installed on the installation structure.

[0014] Furthermore, the mounting structure includes an upper L-shaped plate, a lower L-shaped plate, a mounting threaded rod, and two locking nuts. The mounting threaded rod is symmetrically distributed on both sides of the upper and lower L-shaped plates and passes through the upper and lower L-shaped plates. Two locking nuts are respectively distributed at both ends of the mounting threaded rod and are threadedly connected to the mounting threaded rod.

[0015] Furthermore, the monitoring module includes a pad, a pressure sensor, and a pressure plate. Pads are fixedly installed on the sides of both the upper and lower L-shaped plates; pressure sensors are fixedly installed on each pad; and pressure plates, which are positioned opposite to the pads, are fixedly installed on the sides of both the lower and upper anti-slip seats.

[0016] To better achieve the objectives of this invention, this invention also provides a hoisting method for anchor beam and anchor bolt construction, comprising the following steps:

[0017] Step 1: Secure the lower and upper anti-slip seats to the anchor beam using the upper and lower fixing nuts and the fixing threaded rod; install monitoring component one on the anchor beam;

[0018] Step 2: The construction crane is connected to the lifting point unit via lifting ropes to lift the anchor beam; during the lifting process, the monitoring component 1 detects whether there is any slippage between the lower anti-slip seat, the upper anti-slip seat and the anchor beam. If slippage is found, the alarm component is activated to warn the construction personnel.

[0019] Step 3: After the anchor beam is hoisted, remove the lower and upper anti-slip seats so that the lower and upper anti-slip seats can be used to fix the anchor rod after rotating 90 degrees; fix the bottom of the anchor rod through the limiting structure and connect the limiting structure to the lowermost upper anti-slip seat on the anchor rod.

[0020] Step 4: During the hoisting process, the tension of the hoisting rope is monitored by a tension sensor; the status of the limiting structure is detected by monitoring component 2. If the force on the limiting structure suddenly increases, the alarm component will be automatically activated to warn the construction personnel; the force on the limiting structure is calculated by monitoring component 2, and the anchor bolt posture and hoisting rope tension are combined to determine whether to continue construction.

[0021] Furthermore, by monitoring component two, the force 'a' on the limiting structure is calculated. The limiting structure is fixed to the anchor rod by 'b' bolts. Dividing 'a' by 'b' yields the force borne by a single bolt. This force is then compared to the design value of the connecting hole. If the force on a single bolt is greater than or equal to the design value of the connecting hole, construction is immediately stopped. If the force on a single bolt is less than the design value of the connecting hole, the component of the tension in the hoisting rope along the anchor rod direction is compared to the shear design value of the fixed threaded rod. If the component of the tension in the hoisting rope along the length of the anchor rod is greater than or equal to the shear design value of the fixed threaded rod, construction is immediately stopped. If the component of the tension in the hoisting rope along the length of the anchor rod is less than the shear design value of the fixed threaded rod, other monitoring data can be used to determine whether construction should continue.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] 1. After the anchor beam is hoisted, directly remove the lower anti-slip seat, upper anti-slip seat, fixed threaded rod, upper fixing nut, and lower fixing nut, and use them to hoist the anchor rod. By making the distance between the fixed threaded rods on the same side consistent with the bottom width of the anchor beam, and the distance between the fixed threaded rods on both sides consistent with the bottom width of the anchor rod, the lower and upper anti-slip seats can be used to hoist the anchor rod after rotating 90 degrees, maximizing the contact area between the lower and upper anti-slip seats and the anchor beam or anchor rod, and making full use of the hoisting equipment.

[0024] 2. The monitoring component detects the relative status between the lower anti-slip seat, the upper anti-slip seat, and the anchor beam. If there is a slight slippage between the lower anti-slip seat, the upper anti-slip seat, and the anchor beam, an alarm is triggered by the alarm component, and work is stopped immediately. The monitoring component can also prevent the lower and upper anti-slip seats from sliding, thus avoiding sudden imbalance between the lower anti-slip seat, the upper anti-slip seat, and the anchor beam, providing construction personnel with time to avoid and handle the situation, and ensuring construction safety.

[0025] 3. Install the lifting auxiliary plate at the bottom of the anchor beam. Connect the construction crane to the lifting ring via lifting ropes, and the auxiliary crane to the lifting auxiliary plate via lifting ropes. The construction crane and auxiliary crane lift synchronously. After lifting, the bottom of the anchor beam will be off the ground. At this point, remove the lifting auxiliary plate from the anchor beam. During the lifting process, the construction crane moves the anchor beam to the installation position. The lifting auxiliary plate prevents the tail of the anchor beam from dragging on the ground during lifting, thus avoiding damage. By setting two fixed lifting points and adjusting the position of one side of the fixed lifting point and lifting ring through the adjustment structure, the lifting center is changed, so that the anchor beam is in the installation posture along the width direction after lifting, which facilitates the subsequent alignment and installation of the anchor beam.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0040] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 and Figure 9A hoisting assembly for anchor beam and anchor rod construction includes a hoisting tool 1, a limiting structure 2, and a hoisting point unit 4. When hoisting the anchor beam 10, two sets of hoisting tools 1 are used to fix the anchor beam 10. When hoisting the anchor rod 20, three sets of hoisting tools 1 and at least one set of limiting structures 2 are used to fix the anchor rod 20. The limiting structure 2 is used to be installed on the connecting end of the anchor rod 20 and can be connected to the hoisting tool 1 located on the anchor rod 20 near the connecting end.

[0041] like Figure 2 and Figure 5 As shown, the lifting device 1 includes a lower anti-slip seat 11, an upper anti-slip seat 12, at least four fixed threaded rods 13, an upper fixing nut 14, and a lower fixing nut 15. The four fixed threaded rods 13 are arranged in a rectangular array on the lower anti-slip seat 11 and the upper anti-slip seat 12, and the fixed threaded rods 13 pass through the lower anti-slip seat 11 and the upper anti-slip seat 12. The upper fixing nut 14 is located on the upper side of the upper anti-slip seat 12 and is threadedly connected to the fixed threaded rods 13. The lower fixing nut 15 is located on the lower side of the lower anti-slip seat 11 and is threadedly connected to the fixed threaded rods 13. The distance between the fixed threaded rods 13 on the same side is the same as the bottom width of the anchor beam 10, and the distance between the fixed threaded rods 13 on both sides is the same as the bottom width of the anchor rod 20. The lifting point unit 4 is installed on the upper anti-slip seat 12.

[0042] like Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment, the hoisting assembly for anchor beam and anchor bolt construction further includes a monitoring mechanism 3. The monitoring mechanism 3 includes a first monitoring component 31, a second monitoring component 32, and an alarm component 33. The first monitoring component 31 is installed on the anchor beam 10, and the alarm component 33 is installed on the first monitoring component 31. The second monitoring component 32 and the alarm component 33 are installed on the limiting structure 2. Specifically, a three-dimensional tilt sensor is also fixedly installed on the upper anti-slip seat 12.

[0043] like Figure 2 , Figure 4 and Figure 6As shown, in one embodiment, the lifting point unit 4 includes fixed lifting points 41, an adjusting structure 42, lifting rings 43, and a lifting auxiliary plate 44. An adjusting structure 42 is installed on one side of the upper anti-slip seat 12, and a set of fixed lifting points 41 is installed on the adjusting structure 42. Another set of fixed lifting points 41 is installed on the other side of the upper anti-slip seat 12. The adjusting structure 42 is used to adjust the position of one set of fixed lifting points 41 relative to the other set of fixed lifting points 41. Each fixed lifting point 41 is equipped with a lifting ring 43. The lifting auxiliary plate 44 is detachably connected to the anchor beam 10 by bolts and nuts. Specifically, the two sets of fixed lifting points 41 are spaced apart in the width direction of the anchor beam 10, and the adjusting structure 42 is used to adjust the position of one set of fixed lifting points 41 relative to the other set of fixed lifting points 41 in the width direction of the anchor beam 10. The construction crane is connected to the lifting rings 43 via lifting ropes, and the auxiliary crane is connected to the lifting auxiliary plate 44 via lifting ropes. A tension sensor for detecting the tension of the lifting ropes is installed on the construction crane.

[0044] In this embodiment, when the hoisting assembly for anchor beam and anchor rod construction is working normally, a hoisting device 1 can be set at the upper end and middle part of the anchor beam 10 respectively. The lower anti-slip seat 11 is placed on the lower side of the anchor beam 10, and the upper anti-slip seat 12 is placed on the upper side of the anchor beam 10. After passing four fixing threaded rods 13 through the lower anti-slip seat 11 and the upper anti-slip seat 12, the lower anti-slip seat 11, the upper anti-slip seat 12 and the fixing threaded rods 13 are tightened by the upper fixing nut 14 and the lower fixing nut 15, so that the lower anti-slip seat 11 and the upper anti-slip seat 12 are clamped on the upper and lower sides of the anchor beam 10. At the same time, a monitoring component 31 is installed on one side of the hoisting device 1 located in the middle of the anchor beam 10, so that the monitoring component 31 is in contact with the lower anti-slip seat 11 and the upper anti-slip seat 12.

[0045] The lifting auxiliary plate 44 is installed at the bottom of the anchor beam 10, and the construction crane is connected to the lifting ring 43 via a lifting rope. The auxiliary crane is connected to the lifting auxiliary plate 44 via a lifting rope. The construction crane and the auxiliary crane lift synchronously. After lifting, the bottom of the anchor beam 10 is lifted off the ground. At this time, the lifting auxiliary plate 44 is removed from the anchor beam 10. The construction crane then moves the anchor beam 10 to the installation position. The lifting auxiliary plate 44 is used to prevent the tail of the anchor beam 10 from dragging on the ground during lifting, thus avoiding damage. By adjusting the adjusting structure 42, the position of a set of fixed lifting points 41 and lifting ring 43 in the width direction of the anchor beam 10 is adjusted, changing the lifting center so that the anchor beam 10 is in the installation posture with an inclination angle along the width direction after lifting, which facilitates the subsequent alignment and installation of the anchor beam 10.

[0046] During hoisting, the tension of the hoisting ropes is detected by a tension sensor; the relative state between the lower anti-slip seat 11, the upper anti-slip seat 12, and the anchor beam 10 is detected by monitoring component 31. If there is a slight slippage between the lower anti-slip seat 11, the upper anti-slip seat 12, and the anchor beam 10, an alarm is triggered by alarm component 33, and work is immediately stopped. At the same time, monitoring component 31 prevents the lower anti-slip seat 11 and the upper anti-slip seat 12 from sliding, avoiding sudden imbalance between the lower anti-slip seat 11, the upper anti-slip seat 12, and the anchor beam 10, providing construction personnel with time to avoid and handle the situation, and ensuring construction safety.

[0047] After the anchor beam 10 is hoisted, the lower anti-slip seat 11, upper anti-slip seat 12, fixing threaded rod 13, upper fixing nut 14, and lower fixing nut 15 can be removed and used to hoist the anchor rod 20. By aligning the distance between the fixing threaded rods 13 on the same side with the bottom width of the anchor beam 10, and the distance between the fixing threaded rods 13 on both sides with the bottom width of the anchor rod 20, the lower anti-slip seat 11 and upper anti-slip seat 12 can be used to hoist the anchor rod 20 after rotating 90 degrees. This maximizes the contact area between the lower anti-slip seat 11 and upper anti-slip seat 12 and the anchor beam 10 or anchor rod 20, thus fully utilizing the lower anti-slip seat 11 and upper anti-slip seat 12.

[0048] After the threaded rod 13 passes through the lower anti-slip seat 11 and the upper anti-slip seat 12, it is fixed by the upper fixing nut 14 and the lower fixing nut 15, thereby making the lower anti-slip seat 11 and the upper anti-slip seat 12 fit tightly with the anchor rod 20, achieving clamping and fixing of the anchor rod 20. The bottom of the anchor rod 20 is fixed by the limiting structure 2, and the limiting structure 2 is connected to the lowermost upper anti-slip seat 12 on the anchor rod 20, providing support force during hoisting and preventing slippage between the lower anti-slip seat 11, the upper anti-slip seat 12 and the anchor rod 20.

[0049] During the hoisting of anchor rod 20, the tension of the hoisting rope is monitored by a tension sensor. The construction crane connects to the lifting ring 43 via the hoisting rope, then lifts anchor rod 20 and moves it to the corresponding installation position. During this process, the status of the limiting structure 2 is detected by monitoring component 2 32. If the force on the limiting structure 2 suddenly increases, it indicates that there is relative movement between the lower anti-slip seat 11 and the upper anti-slip seat 12 and the anchor rod 20, and the alarm component 33 is automatically activated to warn the construction personnel. At the same time, the tilt angle ɵ of anchor rod 20 can be read by the three-dimensional tilt sensor on the upper anti-slip seat 12, and the tension P of the hoisting rope connected to the lower lifting ring 43 can be read by the tension sensor. The construction personnel can calculate the force on the limiting structure 2 through monitoring component 2 32 and make a comprehensive judgment based on the force on the limiting structure 2. Through monitoring component 1 31, monitoring component 2 32, alarm component 33, and limiting structure 2, hoisting safety is ensured, sudden instability during hoisting is avoided, and construction personnel are given time to judge and deal with the situation.

[0050] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 6 As shown, the limiting structure 2 includes a limiting plate 21, an ear plate 22, a tie rod 23, and a locking nut 24. The limiting plate 21 is fixedly installed on the connecting end of the anchor rod 20 by bolts and nuts. The ear plate 22 is fixedly installed on the limiting plate 21. The ear plate 22 is fixedly installed on the upper anti-slip seat 12 located at the lowest side of the anchor rod 20. After one end of the tie rod 23 is threadedly connected to a set of locking nuts 24, the other end passes through the ear plate 22 on the limiting plate 21 and the upper anti-slip seat 12 in sequence and is threadedly connected to another set of locking nuts 24.

[0051] like Figure 8 As shown, in one embodiment, the monitoring component 2 32 includes a pad 321 and a pressure sensor 2 322. The pressure sensor 2 322 is fixedly installed on the ear plate 22 on the limiting plate 21. The pad 321 is disposed on the pull threaded rod 23 and is located between the pressure sensor 2 322 and the locking nut 24.

[0052] Specifically, the warning component 33 includes a micro switch 331 and an indicator light 332. The indicator light 332 is fixedly installed on the limiting plate 21. A micro switch 331 for controlling the indicator light 332 is fixedly installed on the ear plate 22 on the limiting plate 21. The micro switch 331 is located between the ear plate 22 and the pad 313.

[0053] like Figure 3 , Figure 6 and Figure 8 As shown, when hoisting the anchor rod 20, the limiting plate 21 is fixed to the connecting end of the anchor rod 20 with bolts, and the limiting plate 21 is fixed to the upper anti-slip seat 12 on the lowest side of the anchor rod 20 by the ear plate 22, the tie thread rod 23 and the locking nut 24, so as to limit the anchor rod 20 during hoisting. After hoisting, if there is no relative movement between the lower anti-slip seat 11 and the upper anti-slip seat 12 and the anchor rod 20, the squeezing force of the pad 321 between the locking nut 1 24 and the ear plate 22 on the pressure sensor 2 322 remains unchanged; if there is relative movement between the lower anti-slip seat 11 and the upper anti-slip seat 12 and the anchor rod 20, the anchor rod 20 will drive the limiting plate 21 to move downward, thereby driving the tie rod 23 to move downward through the ear plate 22. At this time, the tension of the tie rod 23 increases, and the locking nut 1 24 squeezes the pressure sensor 2 322 through the pad 321, causing the value of the pressure sensor 2 322 to increase; at the same time, the locking nut 1 24 squeezes the micro switch 331, thereby turning on the indicator light 332 to warn the construction personnel.

[0054] At this time, the threaded rod 23 applies a tensile force along its length to the limiting plate 21. By reading the value of pressure sensor 322, the pressure on pressure sensor 322 is equal to the tensile force of the threaded rod 23, thus calculating the tensile force applied by the threaded rod 23 to the limiting plate 21. The anchor rod 20 tends to move downwards under gravity, causing the bolts connecting the limiting plate 21 and the anchor rod 20 to experience shear force, resulting in pressure on the connecting holes of the anchor rod 20. If the force borne by the limiting structure 2 is 'a', and the limiting plate 21 and the anchor rod 20 are fixed by 'b' bolts, then 'a' divided by 'b' yields the force borne by a single bolt. The force borne by a single bolt is then compared with the design value of the force on the connecting hole. If the force on a single bolt is less than the design stress value of the connecting hole on the anchor rod 20, the anchor rod 20 can continue to be hoisted without damaging the connecting hole. In this case, the limit plate 21 prevents the anchor rod 20 from moving further, and construction can continue. If the force on a single bolt is greater than or equal to the design stress value of the connecting hole, where the design stress value of the connecting hole can be set to three-fifths of the allowable stress for pressure loss at the bottom connecting hole of the anchor rod 20, then construction must be stopped immediately.

[0055] Meanwhile, when there is no relative movement between the lower anti-slip seat 11 and the upper anti-slip seat 12 and the anchor rod 20, the lower anti-slip seat 11 and the upper anti-slip seat 12 are fastened by the fixed threaded rod 13, so that the lower anti-slip seat 11, the upper anti-slip seat 12 and the anchor rod 20 can be regarded as a rigid whole; when there is no relative movement between the lower anti-slip seat 11 and the upper anti-slip seat 12 and the anchor rod 20, there are opposite forces between the lower anti-slip seat 11 and the upper anti-slip seat 12, thereby forming a shearing force on the fixed threaded rod 13. Therefore, if the force on the connecting bolts of the limiting plate 21 and the anchor rod 20 is less than the design value of the force on the connecting hole, the component of the tension of the hoisting rope along the length of the anchor rod 20 and the shear design value of the fixed threaded rod 13 can be compared. If the component of the tension of the hoisting rope along the length of the anchor rod 20 is greater than or equal to the shear design value of the fixed threaded rod 13, construction should be stopped immediately. If the component of the tension of the hoisting rope along the direction of the anchor rod 20 is less than the shear design value of the fixed threaded rod 13, the specific working conditions and other monitoring data can be used to comprehensively determine whether to continue construction. The shear design value can be set to one-third of the allowable shear stress of the fixed threaded rod 13.

[0056] like Figure 4 and Figure 5As shown, in one embodiment, the monitoring component 31 includes an installation structure and a monitoring module. The installation structure is used to install on the anchor beam 10, and the monitoring module is installed on the installation structure. Specifically, the installation structure includes an upper L-shaped plate 311, a lower L-shaped plate 312, a threaded rod 316, and two locking nuts 317. The threaded rod 316 is symmetrically distributed on both sides of the upper L-shaped plate 311 and the lower L-shaped plate 312, and passes through the upper L-shaped plate 311 and the lower L-shaped plate 312. Two locking nuts 317 are distributed at both ends of the threaded rod 316 and are threadedly connected to the threaded rod 316.

[0057] Specifically, the monitoring module includes a pad 313, a pressure sensor 314, and a pressure plate 315. The pad 313 is fixedly installed on the sides of the upper L-shaped plate 311 and the lower L-shaped plate 312. The pressure sensor 314 is fixedly installed on the pad 313. The pressure plate 315 is fixedly installed on the sides of the lower anti-slip seat 11 and the upper anti-slip seat 12. The pressure plate 315 is positioned opposite to the pad 313.

[0058] like Figure 5 As shown, in one embodiment, another micro switch 331 is fixedly installed on the lower L-shaped plate 312, and another indicator light 332 is fixedly installed on the lower side of the lower L-shaped plate 312; a micro switch 331 for controlling the indicator light 332 is fixedly installed on the lower L-shaped plate 312; the micro switch 331 is located between the pressure plate 315 and the lower L-shaped plate 312.

[0059] See also Figure 1 and Figure 2 When hoisting the anchor beam 10, the upper L-shaped plate 311 and the lower L-shaped plate 312 are placed on the upper and lower sides of the anchor beam 10. The upper L-shaped plate 311 and the lower L-shaped plate 312 are fixed by the threaded rod 316 and the locking nut 317, so that the upper L-shaped plate 311 and the lower L-shaped plate 312 clamp the anchor beam 10. Then, the lower anti-slip seat 11 and the upper anti-slip seat 12 are placed in a position adjacent to the upper L-shaped plate 311 and the lower L-shaped plate 312, so that after hoisting, the position of the upper anti-slip seat 12 is lower than the position of the lower L-shaped plate 312. The pressure plate 315 on the upper anti-slip seat 12 and the lower anti-slip seat 11 is aligned with the pad 313, pressure sensor 314 and micro switch 331 on the upper L-shaped plate 311 and the lower L-shaped plate 312.

[0060] When the lower anti-slip seat 11 and the upper anti-slip seat 12 clamp the anchor beam 10, there is no relative movement between the lower anti-slip seat 11 and the upper anti-slip seat 12 and the anchor beam 10. If the anchor beam 10 slips, the lower anti-slip seat 11, the upper anti-slip seat 12, and the fixing threaded rod 13 move upward along the anchor beam 10 under the action of the hoisting tension, causing the pressure plate 315 of the lower anti-slip seat 11 and the upper anti-slip seat 12 to press the pressure sensor 314 and the micro switch 331. At this time, the upper L-shaped plate 311 and the lower L-shaped plate 312 support the lower anti-slip seat 11 and the upper anti-slip seat 12, preventing the anchor beam 10 from continuing to slip significantly according to its original movement trend. At the same time, the pressure plate 315 pressurizes the micro switch 331, and the micro switch 331 closes to activate the indicator light 332, which makes it easy for construction personnel to detect the problem in time. After moving to a safe position, construction personnel can quickly take emergency measures according to the site conditions.

[0061] like Figure 1 and Figure 7 As shown, in one embodiment, the adjustment structure 42 includes a movable seat 421, a limiting slide groove 422, an adjusting threaded rod 423, and a rotating adjusting block 424. A limiting slide groove 422 is provided on one side of the upper anti-slip seat 12. The movable seat 421 slides within the limiting slide groove 422. The adjusting threaded rod 423 is rotatably mounted on the upper anti-slip seat 12. The adjusting threaded rod 423 and the movable seat 421 are threadedly connected by a threaded sleeve. The rotating adjusting block 424 is fixedly connected to the outer end of the adjusting threaded rod 423.

[0062] Specifically, the fixed suspension point 41 includes a mounting base 411, a rotating mounting platform 412, and a mounting block 413. The mounting base 411 of one set of fixed suspension points 41 is fixedly installed on the upper anti-slip seat 12, and the mounting base 411 of the other set of fixed suspension points 41 is fixedly installed on the movable seat 421. The rotating mounting platform 412 is rotatably installed on the mounting base 411, and the mounting block 413 is fixedly installed on the rotating mounting platform 412. A connecting plate 431 is fixedly installed on the lower side of the lifting ring 43. The connecting plate 431 and the mounting block 413 are provided with connecting holes. The locking pin 432 passes through the connecting holes on the connecting plate 431 and the mounting block 413 and is fixed by a nut.

[0063] The operation of the rotating adjustment block 424 drives the adjusting threaded rod 423 to rotate, thereby causing the movable seat 421 to move horizontally under the limiting action of the limiting slide groove 422, changing the position between the mounting seats 411 on the movable seat 421, and thus changing the installation position of the lifting ring 43 on one side of the upper anti-slip seat 12. Before hoisting, the position of the movable seat 421 can be adjusted according to the installation posture of the anchor beam 10, so that the two lifting rings 43 on the upper anti-slip seat 12 are no longer symmetrically arranged. During hoisting, it is convenient for the anchor beam 10 to rotate along its own width direction to adjust the posture of the anchor beam 10.

[0064] Example 3: In some embodiments, such as Figures 1-9As shown, in a preferred embodiment of the present invention, a hoisting method for anchor beam and anchor bolt construction includes the following steps:

[0065] Step 1: Use the upper fixing nut 14, lower fixing nut 15 and fixing threaded rod 13 to clamp the lower anti-slip seat 11 and upper anti-slip seat 12 to the anchor beam 10; install monitoring component 31 on the anchor beam 10;

[0066] Step 2: The construction crane is connected to the lifting point unit 4 via a lifting rope to lift the anchor beam 10. During the lifting process, the monitoring component 31 detects whether there is any slippage between the lower anti-slip seat 11, the upper anti-slip seat 12 and the anchor beam 10. If there is slippage, the alarm component 33 is activated to warn the construction personnel.

[0067] Step 3: After the anchor beam 10 is hoisted, remove the lower anti-slip seat 11 and the upper anti-slip seat 12 so that the lower anti-slip seat 11 and the upper anti-slip seat 12 can be used to fix the anchor rod 20 after rotating 90 degrees; fix the bottom of the anchor rod 20 through the limiting structure 2, and connect the limiting structure 2 to the lowermost upper anti-slip seat 12 on the anchor rod 20.

[0068] Step 4: During the hoisting process, the tension of the hoisting rope is monitored by the tension sensor; the status of the limiting structure 2 is detected by the monitoring component 2 32. If the force on the limiting structure 2 suddenly increases, the alarm component 33 is automatically activated to warn the construction personnel; then the force on the limiting structure 2 is calculated by the monitoring component 2 32, and the construction is determined whether to continue by combining the attitude of the anchor rod 20 and the tension of the hoisting rope.

[0069] Specifically, in step four, the step of calculating the force on the limiting structure 2 through monitoring component 2 32 and determining whether to continue construction based on the attitude of the anchor rod 20 and the tension of the hoisting rope includes: calculating the force 'a' on the limiting structure 2 through monitoring component 2 32; the limiting structure 2 and the anchor rod 20 are fixed together by 'b' bolts; dividing 'a' by 'b' to obtain the force borne by a single bolt; comparing the force borne by a single bolt with the design value of the force borne by the connecting hole; if the force borne by a single bolt is greater than or equal to the design value of the force borne by the connecting hole, construction is stopped immediately.

[0070] If the force on a single bolt is less than the design value of the force on the connecting hole, the component of the tension of the hoisting rope along the length of the anchor rod 20 is compared with the shear design value of the fixed threaded rod 13. If the component of the tension of the hoisting rope along the length of the anchor rod 20 is greater than or equal to the shear design value of the fixed threaded rod 13, construction is stopped immediately. If the component of the tension of the hoisting rope along the direction of the anchor rod 20 is less than the shear design value of the fixed threaded rod 13, other monitoring data can be used to make a comprehensive judgment on whether to continue construction.

[0071] In one embodiment, the hoisting assembly for the construction of the anchor beam and anchor rod can also be used to hoist the anchor rod 20 first. After the anchor rod 20 is hoisted, the lower anti-slip seat 11 and the upper anti-slip seat 12 are removed, so that the lower anti-slip seat 11 and the upper anti-slip seat 12 are used to fix the anchor beam 10 after rotating ninety degrees.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
