Description

Technical Field

[0001] This utility model relates to the field of seismic bracing technology, and in particular to a seismic bracing for electromechanical engineering. Background Technology

[0002] Electromechanical engineering mainly refers to mechatronics, including mechanical and electrical parts. Seismic bracing is a series of components or devices that limit the displacement of auxiliary electromechanical engineering facilities, control the vibration of facilities, and transfer the load to the load-bearing structure. Seismic bracing should provide reliable protection for building electromechanical engineering facilities during earthquakes and withstand seismic forces from any horizontal direction. Seismic bracing should be verified according to the load it bears. All components that make up seismic bracing should be prefabricated components, and the components that connect fasteners should be easy to install. The seismic bracing limit of insulated pipes should be designed according to the size of the pipe after insulation.

[0003] A seismic bracing system for building electromechanical engineering installation, with announcement number CN221824688U, addresses the shortcomings of existing seismic bracing systems where the angles and lengths of the connecting beams and secondary connecting beams are fixed and cannot be adjusted according to actual conditions, resulting in limitations and inconvenience. The proposed solution includes a load-bearing beam, adjusting components, and limiting components. The load-bearing beam has grooves on both sides, with fixed rods fixedly connected to each groove. Each fixed rod has two adjusting components. The load-bearing beam also has slots at both ends, with limiting components installed in each slot. This invention, through the cooperation of its components, allows for adjustment of the length and angle of the bracing body according to actual conditions. Furthermore, its simple structure and ease of operation greatly improve its practicality and convenience.

[0004] The existing technology described above uses fasteners to fix and limit the insulated pipes, requiring manual rotation of the circular pipes to move the connecting beams one and two away from each other for expansion and contraction adjustment. Multiple adjustment components are used, and operators must manually rotate each circular pipe one by one. This not only consumes a significant amount of time and manpower, increasing labor intensity, but also severely impacts project progress when facing large-scale electromechanical engineering installations or maintenance. Furthermore, it is difficult to ensure uniformity of adjustment; the inability to adjust synchronously leads to low adjustment accuracy, affecting the stability of the support and resulting in poor seismic resistance. Therefore, corresponding improvements are needed. Summary of the Invention

[0005] The purpose of this utility model is to provide a seismic bracing for electromechanical engineering, so as to solve the problems mentioned in the background art, that the existing seismic bracing for electromechanical engineering is cumbersome to adjust and operate and has poor seismic support effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seismic bracing for electromechanical engineering, comprising a seismic bracing main crossbeam and fixed plates, wherein fixed plates are fixed at both ends of the seismic bracing main crossbeam, and mounting holes are provided on the fixed plates;

[0007] The seismic bracing main crossbeam has internal cavities on both sides, and an adjustment mechanism is installed inside each cavity. A U-shaped frame is fixed at the center of the bottom end of the seismic bracing main crossbeam, and a telescopic arm is slidably connected inside the U-shaped frame. Rotating seats are connected to both sides of the telescopic arm, and a support arm is connected to one end of each rotating seat. A rotating seat is connected to the end of each support arm away from rotating seat. A seismic arm is connected to one end of each rotating seat. A bracket is connected to the bottom of the seismic arm, and a support frame is connected inside the bracket. A long screw is connected between the bracket and the support frame. A warning mechanism is provided at the bottom outer side of the telescopic arm.

[0008] Furthermore, the adjustment mechanism includes a protective frame, which is fixed to the outside of the main crossbeam of the seismic brace. A worm gear is connected inside the protective frame, and a worm wheel is engaged at the top of the worm gear. A bidirectional lead screw is fixed inside the worm wheel. One end of the bidirectional lead screw extends into the internal cavity. Both ends of the bidirectional lead screw are threadedly connected to threaded blocks, and the bottom ends of the threaded blocks are movably connected to the top of the seismic arm.

[0009] Furthermore, the seismic bracing has movable grooves on both sides of the bottom end of the main crossbeam, and the threaded block slides laterally in the movable grooves.

[0010] Furthermore, T-shaped blocks are fixed on both sides of the telescopic arm, and rectangular grooves are provided on both sides of the U-shaped frame. The T-shaped blocks slide in the rectangular grooves. Locking holes are evenly provided on both sides of the U-shaped frame of the rectangular grooves. Fixing bolts are connected to both sides of the T-shaped blocks, and one end of the fixing bolts extends into the locking hole.

[0011] Furthermore, the warning mechanism includes a display slot, which is located on the outside of the telescopic arm. A warning block is movably connected inside the display slot, and auxiliary blocks are fixed on both sides of the warning block. Support slots are provided inside the telescopic arms on both sides of the display slot, and the auxiliary blocks slide in the support slots.

[0012] Furthermore, each of the auxiliary blocks is connected to a support spring at its bottom end, and each of the two outer ends of the warning block is connected to a steel wire rope. Each of the warning blocks is connected to an electrode block one at its bottom end, and a motor block two is connected to the display slot below the electrode block one.

[0013] Furthermore, a warning light is connected to the outside of the telescopic arm. The first electrode block is connected to the positive terminal of the power supply via a wire. The second motor block is connected to one end of a current-limiting resistor via a wire. The other end of the current-limiting resistor is connected to the positive terminal of the warning light. The negative terminal of the warning light is connected to the negative terminal of the power supply via a wire.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the seismic bracing for electromechanical engineering not only has the function of adjustment, but also has the function of pipeline tilt warning, to prevent pipelines from falling during electromechanical engineering installation;

[0015] The main crossbeam of the seismic bracing system is fixed with bolts to the fixed leaf plate, ensuring a stable connection. The U-shaped frame enhances the vertical load-bearing capacity, directly bearing the vertical load transmitted from the main crossbeam and evenly distributing it to the support arm and seismic arm. This effectively disperses the vibration force and avoids excessive local stress, thereby improving the safety and stability of the main crossbeam of the seismic bracing system. The support arm increases the overall rigidity, effectively resisting deformation caused by earthquakes, reducing the displacement and vibration amplitude of the support, and keeping the electromechanical facilities in a relatively stable position during earthquakes.

[0016] By driving the adjustment mechanism, the seismic arm can move laterally along the built-in cavity, thereby adjusting the support angle of the seismic arm and simultaneously adjusting the height of the telescopic arm to achieve optimal mechanical balance. This ensures that the main crossbeam of the seismic support reaches a state of mechanical balance in all directions. Furthermore, the overall operation is simple and requires minimal manual intervention. The worm gear and worm wheel provide driving force and can effectively lock the adjustment, ensuring stability.

[0017] The insulated pipes used in electromechanical engineering are installed on the long screw along with the support frame. Then, steel wire ropes are tied to the insulated pipes accordingly. If excessive vibration causes the pipes to shift, the steel wire ropes are pulled to make the warning block slide in the display slot and align the electrode block one with the motor block two. Once the electrode block one contacts the motor block two, the circuit is connected, and the warning light illuminates, allowing staff to promptly detect and adjust the situation, thereby improving the safety of using equipment in electromechanical engineering.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 The present invention provides the following technical solution: Example

[0027] To address the inconvenience of adjusting existing seismic bracing systems used in electromechanical engineering, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3An anti-seismic bracing system for electromechanical engineering includes a main crossbeam 1 and fixed plates 2. Fixed plates 2 are fixed to both ends of the main crossbeam 1, and each fixed plate 2 has mounting holes. Internal cavities 101 are provided on both sides of the main crossbeam 1, and an adjustment mechanism 3 is provided inside each cavity 101. The adjustment mechanism 3 includes a protective frame 301 fixed to the outside of the main crossbeam 1. A worm gear 302 is connected inside the protective frame 301, and a worm wheel 303 meshes with the top of the worm gear 302. A bidirectional lead screw 304 is fixed inside the worm wheel 303. One end of the bidirectional lead screw 304 extends into the internal cavity 101, and threaded blocks 305 are threaded to both ends of the bidirectional lead screw 304. The bottom ends of the threaded blocks 305 are movably connected to the top of the anti-seismic arm 4. Moving grooves are provided on both sides of the bottom end of the main crossbeam 1, and the threaded blocks 305... The sliding mechanism slides laterally in the groove. A U-shaped frame 8 is fixed at the center of the bottom of the main crossbeam 1 of the seismic brace. A telescopic arm 9 is slidably connected inside the U-shaped frame 8. Rotary seats 11 are connected to both sides of the telescopic arm 9. A support arm 10 is connected to one end of each rotating seat 11. A rotating seat 2 12 is connected to the end of each support arm 10 away from the rotating seat 11. A seismic arm 4 is connected to one end of each rotating seat 2 12. Support arms 10 are movably connected to both sides of the telescopic arm 9. A seismic arm 4 is connected to one end of each support arm 10. T-shaped blocks 901 are fixed to both sides of the telescopic arm 9. Rectangular grooves 801 are provided on both sides of the U-shaped frame 8. T-shaped blocks 901 slide in the rectangular grooves 801. Locking holes 802 are evenly provided on both sides of the U-shaped frame 8 of the rectangular grooves 801. Fixing bolts 902 are connected to both sides of the T-shaped blocks 901. One end of the fixing bolts 902 extends into the locking hole 802.

[0028] In this embodiment, the fixed plate 2 is fixed to the wall surface using bolts to suspend the bracket. Then, the electromechanical insulation pipe, along with the support frame 6 and long screw 7, is fixed to the bottom of the bracket 5. Next, the U-shaped frame 8, telescopic arm 9, and anti-vibration arm 4 provide seismic support, and the support arm 10 further supports the telescopic arm 9 and anti-vibration arm 4 to prevent concentrated vibration and deformation of the bracket. Then, the worm gear 302 is manually rotated, causing it to mesh with the worm wheel 303, which in turn rotates the worm wheel 303 and the double-acting screw 304. The double-acting screw 304 then engages with the threaded block 305, causing the threaded block 305 to move horizontally and synchronously with the anti-vibration arm 4, thereby adjusting the support angle of the anti-vibration arm 4 and improving the overall seismic resistance. During this process, the T-shaped block 901 slides up and down in the rectangular groove 801. Finally, the T-shaped block 901 is fixed in position using the fixing bolt 902. Example

[0029] This embodiment differs from Embodiment 1 in that it utilizes the warning mechanism 13. Therefore, the following technical solution is disclosed. Please refer to the following for details. Figure 1 , Figure 3 , Figure 5 The bottom end of the seismic arm 4 is connected to a bracket 5, and a support bracket 6 is connected inside the bracket 5. A long screw 7 connects the bracket 5 and the support bracket 6. A warning mechanism 13 is provided at the bottom outer side of the telescopic arm 9. The warning mechanism 13 includes a display slot 1301, which is located on the outer side of the telescopic arm 9. A warning block 1302 is movably connected inside the display slot 1301, and auxiliary blocks 1303 are fixed on both sides of the warning block 1302. Support slots 1305 are provided inside the telescopic arm 9 on both sides of the display slot 1301. The auxiliary blocks 1303 slide in the support slots 1305. Each of the 303 has a support spring 1304 connected to its bottom end. Both ends of the warning block 1302 are connected to steel wire ropes 1307. The bottom end of the warning block 1302 is connected to an electrode block 1306. A motor block 2 1308 is connected to the display slot 1301 below the electrode block 1306. A warning light 14 is connected to the outside of the telescopic arm 9. The electrode block 1306 is connected to the positive terminal of the power supply through a wire. The motor block 2 1308 is connected to one end of a current-limiting resistor through a wire. The other end of the current-limiting resistor is connected to the positive terminal of the warning light 14. The negative terminal of the warning light 14 is connected to the negative terminal of the power supply through a wire.

[0030] In this embodiment, after the pipe is installed into the bracket 5 and the support 6, two steel wire ropes 1307 are then attached to the pipe. During use, when the pipe is subjected to significant vibration or external force, causing it to tilt or shift, the steel wire ropes 1307 are pulled, which in turn causes the warning block 1302 to slide in the display slot 1301 and the auxiliary block 1303 to slide in the support slot 1305. This causes the support spring 1304 to deform, thus mitigating the vibration. Then, the electrode block 1306 moves synchronously until it contacts the motor block 1308. The electrode block 1306 is connected to the positive terminal of the power supply via a wire, and the motor block 1308 is connected to one end of a current-limiting resistor via a wire. The other end of the current-limiting resistor is connected to the warning light 14. The positive terminal of the warning light 14 is connected to the negative terminal of the power supply via a wire. Therefore, when the electrode block 1306 and the motor block 1308 come into contact, the circuit forms a closed loop, which causes the warning light 14 to emit light so that the staff can see it and promptly detect the excessive tilt or displacement of the pipeline, avoid the pipeline from falling, and further improve the safety of the support.
