Description

Technical Field

[0001] The present invention relates to the field of earthquake-resistant support monitoring, and in particular to an intelligent monitoring system for remote operation of an earthquake-resistant support. Background Art

[0002] Seismic supports are used to limit the displacement of attached electromechanical engineering facilities, control the vibration of the facilities, and transfer the load to various components or devices on the bearing structure.

[0003] In related technologies, seismic supports include support rods, diagonal braces, and cross arms. The support rods are arranged vertically, with two rods spaced apart. One end of the support rod is connected to a hexagonal screw joint, which is fixed to the concrete floor slab via expansion bolts, while the other end is fixed to the cross arm. The diagonal brace rods typically form an angle of 30°-45° with the vertical direction. One end is hinged to the concrete floor slab via expansion bolts, while the other end is fixed to the cross arm. The pipe is secured to the cross arm with a clamp. The support rods and diagonal brace rods together tighten the cross arm, ensuring the stability of the pipe.

[0004] However, after the seismic support is installed, if geological vibration or wall damage occurs, the expansion bolt connections of the support rods or diagonal rods may become loose, requiring regular manual inspections, which consumes a lot of manpower and material resources.

[0005] To this end, we propose an intelligent monitoring system for remote operation of seismic supports to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent remote operation monitoring system for earthquake-resistant supports, so as to solve the problem in the above-mentioned background technology that earthquake-resistant supports require manual regular inspections, which consumes a lot of manpower and material resources.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A remote operation intelligent monitoring system for earthquake-resistant supports comprises a plurality of supports, wherein the fixing places of the plurality of supports and the plurality of expansion bolts of the earthquake-resistant supports correspond one to one, and the supports are pressed and fixed to the concrete floor by hexagonal screw joints or hinges, and each support is fixed with an abutment column, and one end of the abutment column extends out of the support; a pull rope, one end of which is fixed to the concrete floor, and the other end is connected to a detection module for detecting whether the end moves, and the pull rope is sequentially wound around the outer wall of the abutment column and is in a taut state; an elastic member is arranged between the expansion bolt and the support, and the elastic force is directed toward the pull rope; a communication module is electrically connected to the detection module and is used to transmit the output signal of the detection module.

[0009] By adopting the above technical solution, when the construction workers install the six-legged screw joint on the expansion bolt, the bracket is clamped and fixed between the hexagonal screw joint and the concrete floor. When the construction workers install the hinge on the expansion bolt, the bracket is clamped and fixed between the hinge and the concrete floor. When installing each bracket, it is necessary to set an elastic member between the bracket and the expansion bolt, and ensure that the elastic member can generate elastic force. Next, one end of the pull rope is fixed, and the other end is wrapped around the outer wall of each abutment column in turn and fixed to the detection end of the detection module, keeping the pull rope in a taut state. When any expansion bolt fixing point becomes loose, the corresponding hexagonal screw joint or hinge at that point loses its pressing force on the bracket. Under the action of the elastic force of the elastic member, the bracket moves toward the pull rope, and the abutment column pushes the pull rope, causing the end of the pull rope connected to the detection module to be displaced. The detection module detects the displacement of the pull rope end and transmits the signal to the management terminal through the communication module, so that the maintenance personnel can promptly obtain information about the loosening of the expansion bolt fixing point. Maintenance personnel can use this monitoring system to determine if expansion bolts are loose, eliminating the need for regular manual inspections and significantly saving manpower and resources. Furthermore, a single detection module can detect any loose expansion bolt, significantly reducing costs.

[0010] In a further embodiment, when the fixing point of the expansion bolt is loosened, the elongation of each bracket is different.

[0011] By adopting the above technical solution, since the extended length of each bracket is different, when one of the expansion bolt fixings becomes loose, the detection module detects a different amount of movement, which can correspond to the loose expansion bolt, allowing maintenance personnel to more efficiently determine the location of the looseness, making the monitoring system more intelligent.

[0012] In a further embodiment, a guide rod is further included, the direction of the guide rod is the same as the elastic force direction of the elastic member, one end of the guide rod is connected to the expansion bolt, the bracket is provided with a guide hole, and the other end of the guide rod is slidably passed through the guide hole.

[0013] By adopting the above technical solution, with the cooperation of the guide rod and the guide hole, the extension of the bracket is more stable, so that the displacement caused by the abutment column pushing the pull rope is more accurate, and the monitoring system can judge the loose position more accurately.

[0014] In a further embodiment, the expansion bolt is provided with a clamping member for clamping and fixing the end of the guide rod to the expansion bolt.

[0015] By adopting the above technical solution, under the action of the clamping part, even if the expansion bolt becomes loose, the guide rod can still maintain its direction, further increasing the stability of the bracket extending outward, making the bracket push the pull rope more precise, and the detection module can more accurately distinguish the location where the looseness occurs.

[0016] In a further embodiment, a push switch is further included, which is electrically connected to the detection module and is used to control the opening and closing of the detection module; the pull rope drives the push switch pressure head through the push assembly and transmits the displacement of the pull rope end; when the expansion bolt fixing part is not loose, the push switch controls the detection module to close; when the expansion bolt fixing part is loose, the pull rope moves, and the pull rope drives the push assembly to squeeze the pressure head of the push switch, the push assembly transmits the displacement of the pull rope end, and the push switch controls the detection module to open.

[0017] By adopting this technical solution, the detection module does not operate when the expansion bolt is not loose. It only operates after the expansion bolt becomes loose. This saves energy and reduces the operating time of the detection module, extending its service life. Furthermore, the pull cord is directly used as the driving force to drive the pressing assembly, reducing the use of external energy.

[0018] In a further embodiment, the pressure assembly includes: a driving block, which is slidably set on the concrete floor, and the sliding direction is the same as the moving direction of the end of the pull rope, and one end of the driving block is connected to the end of the pull rope; a pushing block, which is slidably set on the concrete floor, and is used to squeeze the pressure head of the pressure switch; an inclined surface is set at one end of the driving block connected to the pull rope, and the inclined surface is located on the side of the driving block close to the pushing block, and the end of the pushing block is movably abutted against the inclined surface; the detection module includes a linear displacement sensor, and the pulling end of the linear displacement sensor is fixed to the end of the driving block away from the pull rope.

[0019] By adopting the above technical solution, when the expansion bolt fixing is not loose, the end of the push block abuts against the inclined surface. When the expansion bolt fixing is loose, the bracket pops out, and the end of the pull rope pulls the drive block to move. Under the abutment of the inclined surface, the push block moves toward the pressure head of the pressure switch. When the push block and the inclined surface are separated, the push block moves to the extreme position, and the drive block can be further pulled by the pull rope, and the pressure switch controls the detection module to open. During the entire movement of the drive block, the drive block pulls the pulling end of the linear displacement sensor. After the detection module is turned on, the linear displacement sensor can detect the amount of pulling of the pull rope.

[0020] In a further embodiment, the minimum displacement of the pull rope end is s, the pressing momentum of the pressure head when the pressure switch is turned on is L, and the angle between the inclined surface and the movement direction of the driving block is α; satisfying: L*cotα≤s.

[0021] By adopting the above technical solution, it can be ensured that after the pressure head of the push switch is pressed to the limit position, the end of the push block and the inclined surface are separated, ensuring that the pull rope can pull the drive block, thereby not affecting the movement stroke of the pull rope end.

[0022] In a further embodiment, one end of the push block close to the driving block is configured to be in an arc shape.

[0023] By adopting the above technical solution, the resistance between the end of the push block and the inclined surface can be reduced.

[0024] In a further embodiment, a locking assembly is arranged between the pull rope and the concrete floor, and the locking assembly includes a mounting rod and a locking rod; the mounting rod is fixed to the concrete floor, and is provided with a through-hole for the pull rope to pass through, and the locking rod is threadedly connected to the mounting rod, and the end of the locking rod presses the pull rope against the side wall of the through-hole.

[0025] By adopting the above technical solution, when the construction workers fix the end of the pull rope to the concrete floor, they only need to pass the pull rope into the perforation, and then tighten the locking rod to press the pull rope against the side wall of the perforation, making the fixing of the pull rope more convenient and quick.

[0026] In a further embodiment, a pulley is coaxially rotatably provided on the abutment column, and the pull rope is sequentially wound around the outer side wall of the pulley.

[0027] By adopting the above technical solution, under the action of the pulley, the friction between the pull rope and the abutment column when the pull rope moves can be reduced.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. By configuring a bracket, abutment column, elastic member, pull rope, detection module, and communication module, maintenance personnel can use the monitoring system to determine if expansion bolts are loose, eliminating the need for manual regular inspections and significantly saving manpower and resources. Furthermore, a single detection module can detect any loose expansion bolt, significantly reducing costs.

[0030] 2. By making each bracket extend by a different amount, when one of the expansion bolt fixings becomes loose, the detection module detects a different amount of movement, which can correspond to the loose expansion bolt, allowing maintenance personnel to more efficiently determine the location of the loosening and making the monitoring system more intelligent.

[0031] 3. By providing a pressure assembly and a pressure switch, the detection module does not operate unless the expansion bolt is loose. It only operates after the expansion bolt is loosened. This saves energy, reduces the detection module's operating time, and extends its service life. Furthermore, the pull cord is used directly as the driving force to drive the pressure assembly, reducing the use of external energy.

[0032] During the monitoring of the seismic support by the present invention, if any expansion bolt fixing point becomes loose, the compressive force of the corresponding hexagonal screw joint or hinge on the support disappears. Under the action of the elastic force of the elastic member, the support moves toward the pull rope, and the abutment column pushes the pull rope, causing the end of the pull rope connected to the detection module to be displaced. The detection module detects the displacement of the pull rope end and transmits the signal to the management terminal via the communication module, allowing maintenance personnel to promptly learn of the loosening of the expansion bolt fixing point. Maintenance personnel can use this monitoring system to detect whether the expansion bolt has become loose, eliminating the need for manual regular inspections, greatly saving manpower and material resources.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] See also Figure 1-Figure 3 The present application provides an embodiment of an intelligent monitoring system for remote operation of an anti-seismic bracket 4, which includes a bracket 4, a pull rope 5, a detection module 6, an elastic member 7 and a communication module 8. The bracket 4 is provided with multiple brackets 4, and the fixing places of the multiple expansion bolts of the anti-seismic bracket 4 correspond one to one. The hexagonal screw joint 12 or the hinge 21 presses the bracket 4 to the concrete floor. Each bracket 4 is fixed with an abutment column 41, and one end of the abutment column 41 extends out of the bracket 4. One end of the pull rope 5 is fixed to the concrete floor, and the other end of the pull rope 5 is connected to the detection module 6. The detection module 6 is used to detect the movement of the pull rope 5. The pull rope 5 is sequentially wound around the outer wall of each abutment column 41 and is in a taut state. The elastic member 7 is arranged between the expansion bolt and the bracket 4, and the elastic force is directed toward the pull rope 5. The communication module 8 is electrically connected to the detection module 6 for transmitting the output signal of the detection module 6.

[0049] In this embodiment of the present application, to facilitate the fixation of the detection module 6 and the communication module 8, and the fixation between the pull rope 5 and the concrete floor, a mounting plate 11 is fixed between the two support rods 1 of the seismic support 4. The detection module 6 and the communication module 8 are fixed to the mounting plate 11, and one end of the pull rope 5 is fixed to the mounting plate 11.

[0050] To allow maintenance personnel to identify which expansion bolt's fixing point has become loose, in the embodiment of the present application, each bracket 4 extends by a different amount when the fixing point of the expansion bolt becomes loose. Because each bracket 4 extends to a different length, when one of the expansion bolt's fixing points becomes loose, the detection module 6 detects a different amount of movement, thereby corresponding to the loosened expansion bolt. This allows maintenance personnel to more efficiently determine the location of the loosening, making the monitoring system more intelligent.

[0051] When the bracket 4 is extended, it is subject to the resistance of the pull rope 5 on the one hand and the elastic force of the elastic member 7 on the other. Due to the deviation of the installation, the elastic force and the resistance are not parallel and there is a certain deviation. Therefore, when the bracket 4 pops out, the bracket 4 may rotate to a certain extent, thereby affecting the amount of push of the abutment column 41 on the pull rope 5 and affecting the accuracy of the monitoring system in determining the loose position. Therefore, in order to reduce the rotation of the bracket 4 when it pops out and make the extension of the bracket 4 more stable, refer to Figure 3 A guide rod 9 is also provided at the expansion bolt. The orientation of the guide rod 9 is the same as the direction of the elastic force of the elastic member 7. One end of the guide rod 9 is connected to the expansion bolt. The bracket 4 is provided with a guide hole 42. The other end of the guide rod 9 slides through the guide hole 42. The cooperation between the guide rod 9 and the guide hole 42 makes the extension of the bracket 4 more stable, thereby making the displacement of the pull rope 5 caused by the abutment column 41 more accurate, allowing the monitoring system to more accurately determine the loose position.

[0052] In actual use, the guide rod 9 may still have a certain degree of deflection. In order to solve this problem, refer to Figure 3 The expansion bolt is provided with a clamping piece 91 that clamps the end of the guide rod 9 to the expansion bolt. Specifically, a collar is fixed to the end of the guide rod 9 away from the bracket 4, and the collar is sleeved on the expansion bolt. The clamping piece 91 is a nut, and the nut is threadedly connected to the expansion bolt.

[0053] For the support rod 1, the support rod 1 is connected to the expansion bolt via the hexagonal screw joint 12, and the collar is clamped and fixed between the hexagonal screw joint 12 and the nut. For the diagonal tie rod 2, the hinge 21 is connected to the expansion bolt via the locking nut, and the collar is clamped and fixed between the locking nut and the nut. Even if there is a certain amount of looseness between the expansion bolt and the concrete floor, the expansion bolt is still difficult to rotate relative to the concrete floor. Because the nut can still maintain the preload between the hexagonal screw joint or the locking nut, the guide rod 9 is always clamped and fixed. Therefore, during the process of the bracket 4 popping out, the guide rod 9 can always maintain its original orientation, thereby providing good guidance for the bracket 4, further increasing the stability of the bracket 4 extending outward, making the bracket 4 push the pull rope 5 more precise, and the detection module 6 can more accurately identify the location of the looseness. In addition, due to the presence of the clamping member 91, the connection between the expansion bolt and the hexagonal screw joint or hinge is more stable, improving the stability of the seismic support itself.

[0054] Specifically, the elastic member 7 can be a spring or other elastic component such as a spring or a spring. For convenience, in the embodiment of the present application, the elastic member 7 is a spring, which is sleeved on the guide rod 9. One end of the spring is tightly against the bracket 4, and the other end of the spring is tightly against the nut. When the bracket 4 is not ejected, the spring is in a compressed state.

[0055] Further, refer to Figure 4 The monitoring system also includes a pressure switch 61, which is electrically connected to the detection module 6 and is used to control the opening and closing of the detection module 6. A pressure assembly 51 is provided between the end of the pull rope 5 and the detection module 6. The pull rope 5 drives the pressure head 611 of the pressure switch 61 through the pressure assembly 51 and transmits the displacement of the end of the pull rope 5. When the expansion bolt fixing part is not loose, the pressure switch 61 controls the detection module 6 to be closed. When the expansion bolt fixing part is loose, the pull rope 5 moves, and the pull rope 5 drives the pressure assembly 51 to squeeze the pressure head 611 of the pressure switch 61. The pressure assembly 51 transmits the displacement of the end of the pull rope 5, and the pressure switch 61 controls the detection module 6 to be opened. Through such a setting, when the expansion bolt is not loose, the detection module 6 does not work. After the expansion bolt is loose, the detection module 6 starts to work, and the displacement of the end of the pull rope 5 is transmitted through the pressure assembly 51, and the detection module 6 can detect the displacement of the end of the pull rope 5. This configuration saves energy, reduces the working time of the detection module 6, and prolongs the service life of the detection module 6. In addition, the pull cord 5 is directly used as a driving force to drive the pressing assembly 51, thereby reducing the use of external energy.

[0056] Specifically, refer to Figure 4 The pressing assembly 51 includes a driving block 511 and a pushing block 512, and the detection module 6 includes a linear displacement sensor (not shown in the figure). A first guide ring 111 is fixed on the mounting plate 11, and the driving block 511 is slidably inserted into the first guide ring 111, and the sliding direction is the same as the moving direction of the end of the pull rope 5. One end of the driving block 511 is connected to the end of the pull rope 5, and the other end of the driving block 511 is connected to the pulling end of the linear displacement sensor. A second guide ring 112 is fixed on the mounting plate 11, and the pushing block 512 is slidably inserted into the second guide ring 112, for squeezing the pressure head 611 of the pressing switch 61. Preferably, the sliding direction of the pushing block 512 is perpendicular to the sliding direction of the driving block 511. An inclined surface is set at one end of the driving block 511 connected to the pull rope 5, and the inclined surface is located on the side of the driving block 511 close to the pushing block 512, and the end of the pushing block 512 is movably abutted against the inclined surface.

[0057] When the expansion bolt fixing is not loose, the end of the push block 512 abuts against the inclined surface. When the expansion bolt fixing is loose, the bracket 4 pops out, and the end of the pull rope 5 pulls the driving block 511 to move. Under the abutment of the inclined surface, the push block 512 moves toward the pressure head 611 of the pressure switch 61. When the push block 512 and the inclined surface are separated, the push block 512 moves to the extreme position, and the driving block 511 can continue to be pulled by the pull rope 5, and the pressure switch 61 controls the detection module 6 to turn on. During the entire movement of the driving block 511, the driving block 511 pulls the pulling end of the linear displacement sensor. After the detection module 6 is turned on, the linear displacement sensor can detect the pulling amount of the pull rope 5.

[0058] In other embodiments, the pressing assembly 51 may still comprise a driving block 511 and a resisting block 512. The difference is that the driving block 511 does not have an inclined surface at its end, while the resisting block 512 does have an inclined surface at its end, and the inclined surface is located on the side of the resisting block 512 closest to the driving block 511. When the driving block 511 is pulled, the end of the driving block 511 closest to the pull cord 5 abuts against the inclined surface of the resisting block 512. Under the action of the inclined surface, the driving block 511 can also cause the resisting block 512 to move toward the pressure head 611.

[0059] Furthermore, the detection module 6 also includes a power supply (not shown in the figure) and a controller (not shown in the figure). In the embodiment of the present application, the linear displacement sensor adopts a voltage output displacement sensor. When the displacement of the pulling end of the linear displacement sensor is different, the voltage output by the output end of the linear displacement sensor is different. The controller is electrically connected to the power supply. The controller can adopt other control elements such as a single-chip microcomputer. In the embodiment of the present application, a single-chip microcomputer is preferably used. The single-chip microcomputer and the ADC chip are used in combination to detect the voltage output by the output end of the linear displacement sensor, and thus the displacement generated by the end of the pull rope 5 is obtained based on the corresponding relationship between voltage and displacement.

[0060] Further, refer to Figure 5 , assuming that the minimum displacement of the end of the pull rope 5 is s, the pressing amount of the pressure head 611 when the pressure switch 61 is turned on is L, and the angle between the inclined surface and the movement direction of the driving block 511 is α. Since the end of the pull rope 5 may still need to move after the pressure head 611 is pressed to the limit position by the push block 512, in order not to hinder the movement of the end of the pull rope 5, when the pressure head 611 is pressed to the limit position by the push block 512, the end of the push block 512 needs to at least be separated from the inclined surface. Therefore, according to the principle of trigonometric function, the dimensions s, L and α need to satisfy: L*cotα≤s. Through such a size setting, it can be ensured that after the pressure head 611 of the pressure switch 61 is pressed to the limit position, the end of the push block 512 and the inclined surface are separated, ensuring that the pull rope 5 can pull the driving block 511, thereby not affecting the movement stroke of the end of the pull rope 5.

[0061] For example, in a preferred setting, when the pressure switch 61 is turned on, the pressing amount of the pressure head 611 is 5 mm, and the minimum displacement of the end of the pull rope 5 is 5 mm. Then, through the aforementioned dimensional relationship, it can be obtained that: cotα≤5 / 5, that is, cotα≤1, and α≥45°. As a preferred option, α is 45°.

[0062] Reference Figure 4 In order to reduce the friction between the push block 512 and the inclined surface, the end of the push block 512 close to the driving block 511 is set to be an arc shape.

[0063] It should be noted that in this embodiment of the present application, communication module 8 may be a Bluetooth module or a Wi-Fi module, and is connected to the signal output terminal of a controller (not shown). The voltage signal output by the linear displacement sensor is processed by the controller and then transmitted to the management terminal via communication module 8, allowing maintenance personnel to promptly detect any loose expansion bolts.

[0064] In order to facilitate the fixation between the pull rope 5 and the concrete floor, refer to Figure 1 and Figure 6 A locking assembly 52 is provided between the pull rope 5 and the mounting plate 11. Specifically, the locking assembly 52 includes a mounting rod 521 and a locking rod 522. The mounting rod 521 is fixed to the concrete floor slab, and is provided with a through-hole 5211 for the pull rope 5 to pass through. The locking rod 522 is threadedly connected to the mounting rod 521, and the end of the locking rod 522 presses the pull rope 5 against the side wall of the through-hole 5211.

[0065] In other embodiments, the locking assembly 52 may also be a stud and a nut. The stud is welded to the mounting plate 11, and the nut is threaded onto the stud. When the construction worker secures the end of the pull rope 5, they wrap a portion of the pull rope 5 around the stud and then tighten the nut to secure the pull rope 5 to the mounting plate 11.

[0066] Further, refer to Figure 2 A pulley 43 is coaxially mounted on the abutment column 41, and the pull rope 5 is sequentially wound around the outer wall of the pulley 43. The pulley 43 reduces the friction between the pull rope 5 and the abutment column 41 during movement, making the movement of the pull rope 5 smoother when the bracket 4 pushes against the pull rope 5.

[0067] The working principle of the embodiment of the present application is as follows: when any expansion bolt fixing point becomes loose, the corresponding hexagonal screw joint 12 or hinge 21's pressing force on the bracket 4 disappears, and under the action of the spring force, the bracket 4 moves toward the pull rope 5, and the abutment column 41 pushes the pull rope 5, causing displacement at one end of the pull rope 5 connected to the detection module 6. The detection module 6 detects the displacement of the end of the pull rope 5 and transmits the signal to the management terminal through the communication module 8, so that the maintenance personnel can promptly know the information that the expansion bolt fixing point has become loose. The maintenance personnel can know whether the expansion bolt has become loose through the monitoring system, without the need for manual regular inspections, which greatly saves manpower and material resources. Moreover, the looseness of any expansion bolt can be detected by only one detection module 6, which greatly saves costs.

[0068] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
