Description

Technical Field

[0001] The present application relates to the field of fire protection equipment installation technology, and in particular to a fire sprinkler installation device. Background Art

[0002] Automatic sprinkler fire extinguishing systems are fire-fighting water supply devices that automatically spray water to extinguish fires and simultaneously issue fire alarms. Currently, they are primarily installed in locations with high fire risk and rapid fire spread, unattended warehouses prone to spontaneous combustion, and buildings with high fire safety requirements. Examples include raw material and finished product warehouses in cotton mills, wood processing workshops, large stores, and office spaces.

[0003] In order to be able to implement sprinkler fire extinguishing in a timely manner, it is often necessary to hang fire pipes on the indoor roof to supply water for the indoor sprinklers. Existing fire water supply pipes are mostly installed using earthquake-resistant brackets, which mainly use screw anchors to connect the clamps and other parts that fix the fire pipes to the roof. Then, the clamps are connected to the clamps through inclined channel steel, and the inclined channel steel is fixed to the roof through anchors to provide vertical and lateral support for the clamps installed on the fire pipes. This allows the fire pipes to be installed relatively stably on the roof. At the same time, the inclined channel steel shares the load of the fire pipes, so that the impact load of the fire pipes during earthquakes or vibrations is reduced, achieving a seismic effect.

[0004] However, in actual use, because the fire-fighting pipes are still filled with water, the load on the fire-fighting pipes is relatively large, which will cause certain slight vibrations in the building during daily use. At this time, it will affect the stability of the anchors anchored to the roof. When relatively large vibrations occur, the impact load applied by the fire-fighting pipes to the anchors is relatively large, which can easily cause local anchors to fall off and create safety hazards.

[0005] Therefore, the existing technology often adopts the method of filling the inner side of the clamp with elastic pads and installing buffer springs in the inclined channel steel and screw anchor bolts to make the inclined channel steel and screw anchor bolts elastically expand and contract, thereby providing elastic buffering to reduce the impact of vibration. However, if springs are used for buffering, the clamps and other parts of the fire protection pipes will also have a certain amount of movement during daily use, causing the fire protection pipes to swing during daily use, affecting the reliability and stability of the fire protection system. Summary of the Invention

[0006] In order to enable the fire protection pipe to withstand relatively large impact loads after installation while optimizing stability during daily use, the present application provides a fire protection sprinkler installation device.

[0007] This application provides a fire sprinkler installation device, which adopts the following technical solution:

[0008] A fire sprinkler installation device includes a clamping assembly for installing a fire pipe, two hanging assemblies for hanging the clamping assembly, and a fastening assembly for fastening the hanging assembly to a roof, wherein the hanging assembly includes a hanging rod and two hanging seats, the two hanging seats are respectively connected to the clamping assembly and the fastening assembly, and the hanging seats are slidably connected to the hanging rod, and a buffer structure is respectively provided on the side away from each other of the two hanging seats, and the buffer structure includes a plurality of buffer teeth arranged on the hanging rod and used for fracture buffering, and the plurality of buffer teeth are distributed along the length direction of the hanging rod, and the flexural strength of the plurality of buffer teeth increases successively from the center of the hanging rod toward both ends, and the hanging seat abuts against the buffer tooth with the smallest flexural strength.

[0009] By adopting the above technical solution, when in use, the clamping assembly clamps the fire-fighting pipe and is installed on the roof through the fastening assembly. During use, relatively large vibrations occur, which will cause the hanging seat connected to the clamping assembly to apply a relatively large load to the buffer teeth. At this time, the impact load can be absorbed and buffered by the fracture of the buffer teeth; and there are multiple buffer teeth and the bending strength increases successively, and the impact load can also be buffered and absorbed in sequence to optimize the safety and reliability of the fire-fighting pipe installation and reduce the possibility of the fastening assembly detaching from the roof; and in daily use, since the buffer teeth are buffered by fracture, the hanging seat abuts against the buffer teeth and transfers the load to the roof through the hanging rod. Compared with direct buffering through the spring, it can effectively reduce the possibility of shaking or vibration during daily use, so as to increase stability during daily use.

[0010] Optionally, a relief opening is formed on one side of the buffer tooth toward or away from the center of the hoisting rod, and the cross-sectional areas of the inner walls of the plurality of relief openings decrease sequentially from the center of the hoisting rod toward both ends.

[0011] By adopting the above technical solution, the avoidance opening can further increase the sensitivity of the buffer teeth to impact loads, so as to further optimize the timeliness of buffering.

[0012] Optionally, the lifting rod is provided with a lifting groove extending in the length direction, the lifting seat is clamped and slidably connected to the lifting groove, and a mounting piece for abutting the lifting seat is provided in the lifting groove, the mounting piece includes a mounting seat inserted and detachably connected to the lifting rod, a mounting rod passed through and threadedly connected to the mounting seat, and a mounting slide rotatably connected to the mounting rod, the mounting rod is parallel to the extension direction of the lifting groove, the mounting slide is provided with a buffer opening and the opening is toward the center of the lifting rod, the buffer teeth are fixedly connected to the buffer opening and parallel to the inner wall of the lifting rod, and the lifting seat is inserted in the buffer opening and abuts the buffer teeth.

[0013] By adopting the above technical solution, since the fire-fighting pipe will need to adjust the position of the lifting seat relative to the lifting rod according to the position and actual installation error during installation, so that the fire-fighting pipe can be kept horizontal; and when the height and angle need to be adjusted during actual installation, it is only necessary to rotate the installation rod to make the installation slide slide relative to the installation seat, so that the lifting seat abutting the buffer port can make adaptive angle and lifting height adjustments according to the actual installation position.

[0014] Optionally, the lifting rod is provided with two lifting holes along a length direction perpendicular to the lifting rod, and the lifting holes pass through the mounting slide and the part of the lifting seat located in the buffer port, and the lifting holes are penetrated by mounting bolts for fitting the groove wall of the lifting groove to the outer wall of the mounting slide.

[0015] By adopting the above technical solution, since the lifting seat is arranged in the lifting groove and the buffer port, when it is under load, the side walls of the buffer port and the lifting groove will be subjected to a relatively large impact due to the breakage of the buffer teeth, which may easily lead to the possibility of deformation of the side walls of the lifting groove. At this time, the lifting groove and the buffer port can be restricted by installing bolts to reduce the possibility of deformation of the lifting rod during vibration and causing the lifting seat to detach; at the same time, during installation, it can slide along the lifting hole through the installing bolts to reduce the impact on the installation and position adjustment of the lifting seat.

[0016] Optionally, the inner wall of the buffer opening is trapezoidal in cross section along a direction perpendicular to the hanging rod, and the small end opening of the buffer opening faces away from the hanging rod.

[0017] By adopting the above technical solution, the inner wall of the buffer opening can further limit the possibility of the hanging seat being separated from the hanging rod along the length direction perpendicular to the hanging rod, so as to optimize the stability during use.

[0018] Optionally, the lifting rod is provided with two locking assemblies corresponding one to one to two lifting seats, and the locking assembly includes a locking member for slidingly locking the lifting seat and a locking controller for controlling the locking cancellation of the locking member during an earthquake, and the locking member and the locking controller are both provided on the lifting rod.

[0019] By adopting the above technical solution, the lifting seat can be slidingly locked by the locking member during daily use, and when relatively large vibrations occur, the sliding lock of the locking member is disabled, so that the fire protection pipe can withstand relatively large loads such as external tools during daily maintenance.

[0020] Optionally, the locking member includes a locking rod that is passed through and slidably connected to the lifting rod and a locking electric push cylinder for controlling the sliding of the locking rod. The telescopic end of the locking electric push cylinder is fixedly connected to the lifting rod. The locking controller is used to control the opening and closing of the locking electric push cylinder. The lifting seat is provided with a locking hole for cooperating with the locking rod.

[0021] By adopting the above technical solution, during daily use, the telescopic end of the locking electric push cylinder will remain extended, so that the locking rod is inserted into the locking hole to optimize daily stability; and during vibration, the locking rod will be disengaged from the locking hole under the action of the locking controller, and at this time it can be buffered by the buffer teeth.

[0022] Optionally, the locking controller includes:

[0023] The vibration sensing module is used to sense the vibration level of the building and output a vibration level signal X0;

[0024] The judgment module pre-stores vibration level thresholds X1 and X2, and X2>X1, and is used to receive the vibration level signal X0, compare the vibration level signal with X1 and X2, and generate a first comparison result signal Y;

[0025] The control module is used to receive the first comparison result signal Y. If X0≥X2, a control signal is sent to control the retraction of the telescopic end of the locking electric push cylinder; if X1<X0<X2, a control signal is sent to control the retraction of the telescopic end of the locking electric push cylinder, and after X0<X1, a control signal is sent to control the retraction of the telescopic end of the locking electric push cylinder; if X0<X1, no control signal is sent; and the control module is also used to receive an earthquake early warning signal in the area. If an earthquake early warning signal is received in the area, a control signal is sent to control the retraction of the telescopic end of the locking electric push cylinder.

[0026] By adopting the above technical solution, when the vibration level is relatively small, the locking of the locking part fails, so that the buffer teeth can be used for buffering. At this time, because the vibration level is relatively small, if the buffer teeth are not broken, they can automatically reset and continue to be used. If the vibration level is relatively large, it will cause the buffer teeth to break. At this time, they will not reset and need to be replaced later to optimize reliability during daily use.

[0027] Optionally, the clamping assembly includes a clamping plate and a clamping bolt for clamping the fire-fighting pipe, the clamping plate is an arc-shaped plate structure, the clamping bolts are passed through the two ends of the arc of the clamping plate and are used to fit the clamping plate to the fire-fighting pipe, the hanging seat connected to the end of the hanging rod away from the fastening assembly is connected to the clamping bolt, and a hanging plate is provided between the two ends of the clamping plate, the hanging plate is an arc-shaped plate structure and the two ends are respectively fixedly connected to the two ends of the clamping plate, and the hanging plate is also connected to the fastening assembly.

[0028] By adopting the above technical solution, the hanging plate is connected to the roof through the fastening assembly. At this time, part of the load is applied to the roof through the hanging plate, which will cause the two ends of the hanging plate to have a tendency to elastically bend toward the middle. At this time, the two ends of the clamping plate will also have a tendency to elastically bend toward each other, so that during vibration, the clamping plate can fit more closely to the fire pipe, thereby optimizing stability during use.

[0029] Optionally, the fastening assembly includes a fastening bolt, a fastening expansion tube sleeved on the fastening bolt, and a fastening rod, the screw portion of the fastening bolt is passed through the fastening expansion tube and the hanging seat, and the fastening expansion tube is provided with a plurality of expansion openings on the end away from the hanging seat, the outer wall of the fastening bolt is fixedly connected with a support ring for supporting the fastening expansion tube, the fastening bolt is provided with a fastening hole facing away from the hanging seat opening, the inner wall of the fastening hole is fixedly connected with a fastening tube filled with adhesive, one end of the fastening rod is inserted into the fastening hole and abuts against the fastening tube, and the fastening bolt and the fastening expansion tube are provided with a flow channel for the outflow of adhesive, and the outer wall of the fastening expansion tube is provided with a thread for connecting to the roof.

[0030] By adopting the above technical solution, during installation, the fastening rod will make the adhesive in the fastening tube flow out through the flow channel and combine with the anchor hole in the roof, and then the fastening expansion tube will be gradually inserted into the anchor hole, and in this process, the fastening expansion tube will be threadedly connected to the anchor hole and exert pressure on the adhesive in the anchor hole, so that the adhesive is tightly combined with the inner wall of the anchor hole and the outer wall of the fastening expansion tube, so that the adhesive can stably bond the fastening expansion tube to the inner wall of the anchor hole while also reinforcing the inner wall of the anchor hole. Compared with directly using chemical bolts, the fastening tube arranged in the fastening screw can effectively reduce the situation where the adhesive directly overflows the anchor hole and causes insufficient bonding; and after the fastening expansion tube is threadedly connected to the anchor hole, the fastening bolt will support the tube wall of the fastening expansion tube corresponding to the expansion port through the support ring, so as to further optimize the stability of the connection to the roof while optimizing the convenience during construction.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] During use, the clamping assembly clamps the fire-fighting pipe and is installed on the roof through the fastening assembly. During use, relatively large vibrations occur, which will cause the hanging seat connected to the clamping assembly to apply a relatively large load to the buffer teeth. At this time, the impact load can be absorbed and buffered by the fracture of the buffer teeth; and there are multiple buffer teeth and the bending strength increases successively, and the impact load can also be buffered and absorbed in sequence to optimize the safety and reliability of the fire-fighting pipe installation and reduce the possibility of the fastening assembly detaching from the roof; and in daily use, since the buffer teeth are buffered by fracture, the hanging seat abuts against the buffer teeth and transfers the load to the roof through the hanging rod. Compared with direct buffering through the spring, it can effectively reduce the possibility of shaking or vibration during daily use, so as to increase stability during daily use; at the same time, the locking member can also be used to make the hanging seat slide and lock relative to the hanging rod, so as to further optimize the stability during daily use.

[0043] The following is combined with Figure 1-9 This application is described in further detail.

[0044] The embodiment of the present application discloses a fire sprinkler installation device. Figure 1 and Figure 2 The fire sprinkler installation device includes a clamping assembly 1 for clamping the fire pipe, two hanging assemblies 2 for hanging the clamping assembly 1, and a fastening assembly 3 for connecting the hanging assembly 2 to the roof. The two fastening assemblies 3 are respectively installed on the hanging assemblies 2 in a one-to-one correspondence. The two hanging assemblies 2 are respectively installed on both sides of the clamping assembly 1 along the length of the installed fire pipe, and the two hanging assemblies 2 are distributed in the horizontal direction.

[0045] Reference Figure 1 and Figure 2 The clamping assembly 1 includes a clamping plate 11 and a clamping bolt 12 for clamping the fire pipe. The clamping plate 11 is an arc-shaped plate with a curvature greater than π, which allows for relatively comprehensive clamping of the fire pipe. The curved ends of the clamping plate 11 are bent away from the center of the clamping plate 11 along the opening direction to form clamping connecting plates 111. The clamping bolt 12 is inserted through the two clamping connecting plates 111 to clamp the fire pipe during use.

[0046] Reference Figure 2 and Figure 3At the same time, the two clamping connecting plates 111 are provided with a hanging plate 13. The hanging plate 13 is an arc-shaped plate structure with an arc less than π. The two ends of the arc of the hanging plate 13 are bent toward the center of the clamping plate 11. The two ends of the hanging plate 13 are attached to the outer wall of the two clamping connecting plates 111 on the opposite side. The clamping bolts 12 are passed through the two bent parts of the hanging plate 13. Among them, the hanging plate 13 is also connected to the fastening component 3 for connecting to the roof. The cross-sectional profile of the hanging plate 13 is a broken line or a wavy line to increase the bending strength of the hanging plate 13. The two ends of the clamping bolts 12 are connected to the hanging component 2.

[0047] Of course, in other embodiments, the clamping assembly 1 may also use two arc-shaped clamping plates 11 to clamp the fire protection pipe, and then the two ends of the two clamping plates 11 are fixedly connected to the lifting assembly 2 by bolts.

[0048] During use, since the weight of the fire-fighting pipe is transmitted to the hanging assembly 2 and the fastening assembly 3 through the clamping bolt 12, during this process, since the hanging plate 13 is also connected to the roof through the fastening assembly 3, during this process, the elastic bending of the hanging plate 13 can elastically buffer the vibration; at the same time, during the bending process of the hanging plate 13, the two ends of the clamping plate 11 will be elastically bent toward each other, so as to further optimize the tightness of the fire-fighting pipe being clamped during use.

[0049] Reference Figure 2 and Figure 3 The lifting assembly 2 includes a lifting rod 21 and two lifting seats 22 respectively provided at both ends of the lifting rod 21. The lifting seat 22 at one end of the lifting rod 21 is connected to the clamping bolt 12. Specifically, the clamping bolt 12 is passed through the lifting seat 22. The lifting seat 22 at the other end of the lifting rod 21 is connected to the fastening assembly 3.

[0050] The hoisting rod 21 is provided with a hoisting slot 211 extending along its length and penetrating the hoisting rod 21. The hoisting slot 211 is a T-slot or a dovetail slot, and in the embodiment of the present application, it is a T-slot. The hoisting seat 22 includes a hoisting portion 221 and a hoisting connection portion 222. The hoisting portion 221 is clamped and slidably connected within the hoisting slot 211, and the hoisting portion 221 is adapted to the cross-section of the hoisting slot 211, so that the hoisting portion 221 can slide along the hoisting slot 211 to adapt to different installation heights and angles.

[0051] Reference Figure 2 and Figure 3The hoisting connection portion 222 is a plate-like structure. One end of the hoisting connection portion 222 is integrally formed with the hoisting portion 221, and the other end of the hoisting connection portion 222 is connected to the clamping bolt 12 or the fastening assembly 3. The clamping bolt 12 is inserted into the hoisting connection portion 222 located at the end of the hoisting rod 21 away from the fastening assembly 3. The hoisting connection portion 222 is arranged at an angle to the hoisting rod 21, and the hoisting connection portion 222 is a U-shaped plate-like structure, so that the hoisting connection portion 222 can be elastically bent relative to the hoisting portion 221, thereby providing preliminary buffering against vibration. Among them, the hoisting connection portion 222, the clamping connection plate 111, and both ends of the hoisting plate 13 are located between the screw head and nut of the clamping bolt 12.

[0052] Reference Figure 2 and Figure 3 Specifically, the hoisting rod 21 is provided with two buffer structures 4, and the two buffer structures 4 are respectively located on the side away from the two hoisting parts 221, so as to bear and buffer relatively large impact loads.

[0053] The buffer structure 4 includes a plurality of buffer teeth 41 and mounting members 42 for mounting the buffer teeth 41. The two mounting members 42 on the same lifting rod 21 are located on opposite sides of the two lifting portions 221, respectively, to support the lifting portions 221. The buffer teeth 41 are used to buffer and absorb impact loads by breaking. The buffer teeth 41 are made of brittle materials such as cast iron, ceramic, and hard steel.

[0054] The mounting member 42 includes a mounting seat 421, a mounting rod 422 that passes through and is threadedly connected to the mounting seat 421, and a mounting slide 423 that is rotatably connected to the mounting rod 422. The mounting seat 421 is T-shaped, and its vertical portion is inserted and adapted to the cross-sectional profile of the inner wall of the hanging groove 211. The horizontal portion of the T-shape of the mounting seat 421 fits against the end of the hanging rod 21 and is fixedly connected to the hanging rod 21 via a plurality of bolts, serving as a support base for the mounting rod 422 and the mounting slide 423.

[0055] Reference Figure 3 and Figure 4 The mounting rod 422 is parallel to the hanging rod 21 and is located inside the hanging groove 211. The two mounting slides 423 on the same hanging rod 21 are located on opposite sides of the two mounting rods 422, and the two hanging parts 221 are located on opposite sides of the two mounting slides 423. The mounting slide 423 is provided with a buffer opening 424, and the buffer opening 424 is opened toward the center of the hanging rod 21, so that the mounting slide 423 is U-shaped. The buffer teeth 41 are fixedly connected to the two side portions of the buffer opening 424 parallel to the opening direction, and the multiple buffer teeth 41 connected to the same side wall of the buffer opening 424 have increasing bending strength from the center of the hanging rod 21 toward the end.

[0056] The end of the hanging portion 221 that faces away from the center of the hanging rod 21 is T-shaped, and the small end portion is inserted into and adapted to the buffer opening 424. The hanging portion 221 abuts against the buffer tooth 41 with the smallest flexural strength in the buffer opening 424, thereby limiting the bending of the two side walls of the buffer opening 424 towards each other while providing buffering, thereby optimizing the stability during the installation of the fire protection pipe. A clearance opening 411 is provided on the outer wall of the side of the buffer tooth 41 facing or away from the center of the hanging rod 21, and the area of ​​the cross-sectional profile of the clearance opening 411 corresponding to the same side wall of the buffer opening 424 decreases from the center of the hanging rod 21 toward both ends. In the embodiment of the present application, the clearance opening 411 is provided on the outer wall of the side of the buffer tooth 41 facing the center of the hanging rod 21. The inner wall of the buffer opening 424 is trapezoidal in cross-sectional profile along the direction perpendicular to the length direction of the hanging rod 21, and the small end of the buffer opening 424 opens in a direction away from the central axis of the hanging rod 21, thereby limiting the possibility of the hanging portion 221 detaching from the buffer opening 424.

[0057] During use, the hoisting rod 21 is connected to the roof via the hoisting portion 221 and the hoisting connection portion 222 connected to the fastening assembly 3. When a relatively large vibration occurs, the fire-fighting pipe, filled with water for fire extinguishing, will generate a relatively large impact load applied to the buffer teeth 41. When the impact load is relatively large, the buffer teeth 41 can be broken in sequence to achieve a multi-stage buffering effect, reducing the possibility of the fastening assembly 3 being detached from the roof. At the same time, during daily use, because the hoisting portion 221 abuts against the buffer teeth 41, the clamping assembly 1 can remain stable relative to the roof. Compared to using a spring for buffering, it can effectively reduce the vibration of the clamping assembly 1 caused by the slight vibration of the building during daily use, thereby achieving anti-seismic buffering while effectively optimizing the stability during daily use and reducing the possibility of the fire-fighting pipe falling due to vibration and injuring escaping personnel.

[0058] Reference Figure 3 and Figure 4 Furthermore, to optimize stability during use, the hoisting rod 21 is provided with two hoisting holes 212 perpendicular to its length. The two hoisting holes 212 correspond to the two mounting slides 423. Furthermore, the hoisting holes 212 extend perpendicular to the length of the hoisting rod 21 and the opening of the hoisting slot 211, penetrating the hoisting rod 21, the mounting slides 423, and the portion of the hoisting portion 221 located within the buffer opening 424.

[0059] The lifting hole 212 is provided with a mounting bolt 425 to fasten the groove wall of the lifting groove 211 and make the groove wall of the lifting groove 211 fit into the mounting slide 423, so that the mounting slide 423 clamps the lifting part 221, optimizing the stability of the lifting part 221 inserted in the buffer port 424; it can also further limit the possibility of the mounting slide 423 slipping relative to the lifting rod 21 during use; and when the vibration level is relatively high, the lifting part 221 can overcome the friction force and slide relative to the lifting rod 21, and at this time the mounting bolt 425 will slide relative to the lifting hole 212.

[0060] Of course, in other embodiments, the buffer structure 4 includes a buffer spring and a plurality of buffer connecting blocks. The plurality of buffer connecting blocks are divided into two groups, each of which is connected to two mutually parallel groove walls of the hanging groove 211. The buffer connecting blocks in the same group are distributed along the length of the hanging rod 21 and fixedly connected to the groove walls of the hanging groove 211. The flexural strength of the plurality of buffer connecting blocks increases from the center to the ends of the hanging rod 21. The end of the buffer spring facing the center of the hanging rod 21 and the outer edge are fixedly connected to the inner wall of the hanging groove 211 by the buffer connecting blocks, and the hanging portion 221 abuts the end of the buffer spring facing the center of the hanging rod 21. During use, the buffer spring and the buffer connecting blocks can provide rigid support for the hanging portion 221, reducing vibration during daily use and optimizing stability. At the same time, when vibration occurs, if the impact load exceeds the flexural strength of the buffer connecting blocks, the buffer connecting blocks will break. During this process, the buffer spring can provide support and elastic buffering, thereby achieving optimized stability during use and also buffering vibration.

[0061] Reference Figure 3 and Figure 5 In order to maintain the reliability of the fire protection system, regular maintenance is required during daily use. At this time, the fire protection pipe may need to bear part of the load or some users may lift items through the fire protection pipe during daily use. At this time, if the load is too large, the buffer teeth 41 may break without vibration. In order to optimize the stability during daily use, the lifting rod 21 is provided with a locking assembly 5 to keep the lifting part 221 sliding and locked relative to the lifting rod 21.

[0062] Reference Figure 3 and Figure 5 The same hoisting rod 21 is provided with two locking assemblies 5, and the two locking assemblies 5 are provided one-to-one with the two hoisting parts 221. The locking assembly 5 includes a locking member 51 for slidingly locking the hoisting part 221 and a locking controller 52 for controlling the locking member 51 to cancel the locking during an earthquake.

[0063] The locking member 51 includes a locking rod 511 that passes through and is slidably connected to the hoisting rod 21, and a locking electric push cylinder 512 for controlling the axial sliding of the locking rod 511. The locking rod 511 is perpendicular to the hoisting rod 21, and the sliding path of the locking rod 511 passes through the hoisting slot 211. The locking rod 511 is coaxially fixedly connected to the telescopic end of the locking electric push cylinder 512, and the locking electric push cylinder 512 is fixedly connected to the outer wall of the hoisting rod 21. Among them, the hoisting portion 221 is provided with a locking hole 220 for cooperating with the locking rod 511. The locking hole 220 is located on the sliding path of the locking rod 511, and the locking rod 511 is inserted into the locking hole 220.

[0064] During daily use, the locking rod 511 is inserted into the locking hole 220, so that the lifting part 221 is slidingly locked relative to the lifting rod 21; at the same time, when an earthquake or relatively large vibration occurs, the locking controller 52 can be used to control the telescopic end of the locking electric push cylinder 512 to retract, so that the locking rod 511 is disengaged from the locking hole 220, that is, it can be buffered by the buffer teeth 41; thereby further optimizing the stability during use, it can also buffer the vibration when a relatively large vibration occurs, so as to reduce the possibility of the buffer teeth 41 breaking during daily use.

[0065] Reference Figure 3 and Figure 5 The locking controller 52 includes a vibration sensing module 521 , a judgment module 522 and a control module 523 .

[0066] The vibration sensing module 521 is used to sense the vibration level of the building and output a vibration level signal X0; the vibration sensing module 521 can be a commercially available vibration sensor.

[0067] The judgment module 522 pre-stores vibration level thresholds X1 and X2, and X2>X1, and is configured to receive the vibration level signal X0 and compare the vibration level signal X0 with X1 and X2 to generate a first comparison result signal Y.

[0068] The control module 523 is used to receive the first comparison result signal Y, and send a control signal according to the first comparison result signal Y to control the telescopic end of the locking electric push cylinder 512 to retract, not send a control signal, or send a control signal to control the locking electric push cylinder 512 to keep the telescopic end extended.

[0069] Specifically, if X0 ≥ X2, a control signal is issued to control the telescopic end of the locking electric push cylinder 512 to retract, and the telescopic end of the locking electric push cylinder 512 does not reset after retraction. If X1 < X0 < X2, a control signal is issued to control the telescopic end of the locking electric push cylinder 512 to retract, and after X0 < X1, a control signal is issued to control the telescopic end of the locking electric push cylinder 512 to reset; if X0 < X1, no control signal is issued. Simultaneously, the control module 523 is also used to receive earthquake warning signals in the region. If an earthquake warning signal is received in the region, a control signal is issued to control the telescopic end of the locking electric push cylinder 512 to retract.

[0070] During use, if the building itself experiences relatively large vibrations, such as blasting construction in the surrounding area, or is located in the area affected by an earthquake, the control module 523 will control the locking electric push cylinder 512 and the locking rod 511 will, under the action of the locking electric push cylinder 512, cancel the restriction on the hoisting part 221 so that it can be buffered by the buffer teeth 41; and when the vibration level is relatively low or no earthquake occurs, the sliding lock of the hoisting part 221 can be maintained to optimize stability during daily use.

[0071] Of course, in other embodiments, the locking assembly 5 includes a locking ratchet plate hinged to the lifting rod and a locking control motor for controlling the locking ratchet plate to fit the lifting part 221, the output shaft of the locking control motor is fixedly connected to the locking ratchet plate, and the output shaft of the locking control motor is coaxially arranged with the rotation axis of the locking ratchet plate.

[0072] Reference Figure 6 and Figure 7 The fastening assembly 3 includes a fastening bolt 31, a fastening expansion tube 32, and a fastening rod 33. The fastening bolt 31 includes a fastening screw 313 and a fastening nut 314 that is externally mounted and threadedly connected to the fastening screw 313. The fastening expansion tube 32 is externally mounted on the fastening screw 313, and a plurality of expansion openings 321 are formed on the end of the fastening expansion tube 32 away from the fastening nut 314. The fastening screw 313 is integrally formed with a support ring 311, and the support ring 311 is located on the side of the fastening expansion tube 32 away from the fastening nut 314, so as to support the tube wall corresponding to the expansion opening 321 and abut against the inner wall of the anchor hole in the roof. The outer wall of the fastening expansion tube 32 is threaded for threading into the inner wall of the roof anchor hole. The fastening screw 313 is passed through the hanging plate 13 or the hanging connection portion 222 and is fixed by the fastening nut 314.

[0073] Reference Figure 7 and Figure 8 A fastening hole 312 is opened at one end of the fastening screw 313 away from the fastening nut 314 , and the fastening hole 312 is arranged coaxially with the fastening screw 313 , and the fastening hole 312 is arranged away from the fastening nut 314 and the opening of the hanging seat 22 .

[0074] Reference Figure 8 and Figure 9 A fastening tube 34 is fixedly connected to the inner wall of the fastening hole 312. The interior of the fastening tube 34 is filled with an adhesive, such as structural adhesive, anchoring glue, or anchoring agent. One end of the fastening rod 33 is inserted into the fastening hole 312 and abuts against the end of the fastening tube 34 facing away from the fastening nut 314. The other end of the fastening rod 33 extends out of the fastening hole 312. The extended length of the fastening rod 33 is greater than or equal to the length of the fastening expansion tube 32.

[0075] The inner wall of the fastening tube 34 is fixedly connected to multiple partitions 341, distributed along the length of the fastening screw 313. The partitions 341 divide the fastening tube 34 into multiple cavities filled with adhesive. The wall thickness of the fastening tube 34 corresponding to the multiple cavities increases from the edge of the fastening hole 312 toward the center of the fastening screw 313, resulting in a gradually decreasing strength of the fastening tube 34 from the edge of the fastening hole 312 toward the center of the fastening screw 313. The fastening tube 34 is made of a fragile material, such as glass, brittle plastic, or plastic film.

[0076] Reference Figure 8 and Figure 9 The fastening screw 313 and the fastening expansion tube 32 are provided with a flow channel for the adhesive to flow out, and the flow channel includes a plurality of fastening overflow holes 315 and a fastening overflow ring groove 316 opened on the fastening screw 313 and an expansion groove 322 and an expansion hole 323 opened on the fastening expansion tube 32.

[0077] The tightening overflow hole 315 penetrates the wall of the tightening hole 312. The tightening overflow annular groove 316 is provided around the tightening screw 313 and is connected to the tightening overflow hole 315. The tightening overflow annular groove 316 is formed on the outer wall of the tightening screw 313. The expansion groove 322 extends axially along the tightening expansion tube 32. There are multiple expansion holes 323 and they penetrate the wall of the tightening expansion tube 32. The expansion groove 322 is closed at the end facing the tightening nut 314 and is connected to the expansion hole 323.

[0078] When installing the fastening assembly 3, first extend the fastening screw 313 into the anchor hole, and in this process, the fastening rod 33 will first squeeze the end of the fastening tube 34 away from the fastening nut 314 in sequence, and make the adhesive flow from the fastening overflow hole 315 into the fastening overflow ring groove 316, and then flow into the expansion groove 322, and then flow out from the expansion hole 323 and contact the inner wall of the anchor hole; to reduce the possibility of the adhesive directly overflowing from the anchor hole; and in the process of the fastening rod 33 being inserted into the fastening hole 312, the adhesive is filled The gap between the fastening screw 313 and the anchor hole is formed, and the fastening expansion tube 32 is then threadedly connected to the anchor hole. During this process, the adhesive is filled between the outer wall of the fastening expansion tube 32 and the inner wall of the anchor hole. At the same time, pressure can be applied to the adhesive through the fastening expansion tube 32, so that the adhesive is fully mixed with the surface layer of the inner wall of the anchor hole, so as to fully optimize the stability of the fastening screw 313 connected to the roof and reduce the impact of the impact load when the buffer tooth 41 breaks on the stability of the fastening screw 313 connected to the roof.
