Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anchor beam and anchor rod construction, in particular to a hoisting assembly for anchor beam and anchor rod construction and a hoisting method thereof. BACKGROUND

[0002] When hoisting the anchor beam and anchor rod, precise positioning is required in multiple angles and postures. The anchor beam and anchor rod are characterized by large weight and long size, and the risk of hoisting and sliding is extremely high. The traditional lifting appliance usually needs to be designed separately for the anchor beam and anchor rod to meet the hoisting requirements.

[0003] For example, a steel anchor beam lifting appliance is disclosed in Chinese Patent No. CN221796741U, which adjusts and fixes the length of the device through mechanical operation to adapt to the hoisting of anchor beams of different lengths. For example, a special lifting appliance for anchor rods of a shaped steel anchoring system is disclosed in Chinese Patent No. CN217323011U, which positions and hoists the anchor rod from the outside through a three-dimensional frame structure formed by the cooperation of the upper and lower bases and multiple tie rods.

[0004] For the hoisting of anchor beams and anchor rods, it is necessary to customize the lifting appliance separately, which makes it difficult to fully utilize the lifting appliance. Moreover, the cross-sectional size of the anchor rod is smaller than that of the anchor beam, and the installation distance between the anchor rods is small. If the lifting appliance for hoisting the anchor beam is directly used to fix the anchor rod, the size of the lifting appliance is too large to allow normal installation.

[0005] Therefore, the present application provides a hoisting assembly for anchor beam and anchor rod construction and a hoisting method thereof to solve the above problems. SUMMARY

[0006] In view of the above-mentioned shortcomings of the prior art, the present application provides a hoisting assembly for anchor beam and anchor rod construction and a hoisting method thereof.

[0007] To achieve the above-mentioned purposes, the present application is implemented by the following technical solutions: A hoisting assembly for anchor beam and anchor rod construction, comprising a lifting appliance, a limiting structure and a lifting point unit. The lifting appliance comprises a lower anti-slip base, an upper anti-slip base, at least four fixed threaded rods, an upper fixed nut and a lower fixed nut. The four fixed threaded rods are arranged in a rectangular array on the lower anti-slip base and the upper anti-slip base. The fixed threaded rods pass through the lower anti-slip base and the upper anti-slip base. The upper fixed nut is located on the upper side of the upper anti-slip base and is threadedly connected with the fixed threaded rods. The lower fixed nut is located on the lower side of the lower anti-slip base and is threadedly connected with 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 the two sides is consistent with the bottom width of the anchor rod. The lifting point unit is installed on the upper anti-slip base. The limiting structure is used to be installed on the connecting end of the anchor rod and can be connected with the lifting appliance located on the anchor rod near the connecting end.

[0008] Further, the hoisting assembly for anchor beam and anchor rod construction further comprises a monitoring mechanism, the monitoring mechanism comprising a monitoring component one, a monitoring component two and an alarm component, the monitoring component one being installed on the anchor beam, the alarm component being installed on the monitoring component one; the limiting structure being provided with the monitoring component two and the alarm component.

[0009] Further, the hoisting point unit comprises fixed hoisting points, an adjusting structure, lifting rings and a lifting auxiliary hoarding, one side of the upper anti-skid seat being provided with the adjusting structure, the adjusting structure being provided with a group of fixed hoisting points, the other side of the upper anti-skid seat being provided with another group of fixed hoisting points; each fixed hoisting point being provided with a lifting ring; the lifting auxiliary hoarding being detachably connected with the anchor beam; the construction crane being connected with the lifting rings through hoisting ropes, and the auxiliary crane being connected with the lifting auxiliary hoarding through hoisting ropes.

[0010] Further, the limiting structure comprises a limiting plate, an ear plate, a tension thread rod and a locking nut one, the limiting plate being fixedly installed on the connecting end of the anchor rod through bolts and nuts; the ear plate being fixedly installed on the limiting plate; the ear plate being fixedly installed on the upper anti-skid seat at the lowermost side of the anchor rod; one end of the tension thread rod being threadedly connected with one group of locking nuts one, the other end being threadedly connected with another group of locking nuts one after sequentially penetrating through the ear plates on the limiting plate and the upper anti-skid seat.

[0011] Further, the monitoring component two comprises a cushion block and a pressure sensor two, the pressure sensor two being fixedly installed on the ear plate on the limiting plate; the cushion block being arranged on the tension thread rod and located between the pressure sensor two and the locking nut one.

[0012] Further, the monitoring component one comprises an installation structure and a monitoring module, the installation structure being used for being installed on the anchor beam, the monitoring module being installed on the installation structure.

[0013] Further, the installation structure comprises an upper L-shaped plate, a lower L-shaped plate, an installation thread rod and a locking nut two, the installation thread rod being symmetrically distributed on the two sides of the upper L-shaped plate and the lower L-shaped plate, the installation thread rod penetrating through the upper L-shaped plate and the lower L-shaped plate; two locking nuts two being respectively distributed on the two ends of the installation thread rod and threadedly connected with the installation thread rod.

[0014] Further, the monitoring module comprises a cushion plate, a pressure sensor one and a pressing plate, the side edges of the upper L-shaped plate and the lower L-shaped plate being fixedly provided with the cushion plates; the pressure sensor one being fixedly installed on the cushion plate; the pressing plate being fixedly installed on the side edges of the lower anti-skid seat and the upper anti-skid seat and opposite to the cushion plate.

[0015] In order to better achieve the purpose of the present application, the present application further provides a hoisting method for anchor beam and anchor rod construction, comprising the following steps: Step one: the lower anti-skid seat and the upper anti-skid seat are clamped to the anchor beam through the upper fixed nut, the lower fixed nut and the fixed thread rod; the monitoring component one is installed on the anchor beam; 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. 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. 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.

[0016] 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.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: 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.

[0018] 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.

[0019] 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.

[0023] 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.

[0024] 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.

[0025] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 and Figure 9 A 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.

[0026] like Figure 2 and Figure 5As 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.

[0027] 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.

[0028] like Figure 2 , Figure 4 and Figure 6 As 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] like Figure 4 and Figure 5 As 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.

[0042] 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.

[0043] 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.

[0044] See also Figure 1 and Figure 2When 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] Example 3: In some embodiments, such as Figures 1-9 As shown, in a preferred embodiment of the present invention, a hoisting method for anchor beam and anchor bolt construction includes the following steps: 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; 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. 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. 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.

[0050] 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. 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.

[0051] 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.

[0052] 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.
