Description

Technical Field

[0001] The invention relates to the technical field of building motor installation and fixing, and in particular to an anti-seismic bracket for motor equipment inside a building. Background Art

[0002] The motor equipment inside the building includes fans, water pumps, air-conditioning compressors, elevator drive systems, etc. These devices will generate vibrations during operation and are easily impacted by external forces such as earthquakes, causing displacement or damage. The seismic bracket with seismic springs can not only fix the position of the equipment, but also absorb vibration and impact energy through the springs, effectively alleviating the impact of vibration on the equipment and building structure, and preventing pipes, connectors, etc. from breaking or leaking due to vibration. This type of bracket not only improves the stability of the equipment during operation and earthquakes, but also reduces the noise and vibration transmission inside the building. It is an important component to ensure building safety and long-term stable operation of equipment.

[0003] In the prior art, the top of the seismic spring of the seismic bracket is usually fixed on an integrally formed annular seat. After long-term use, when the seismic bracket carrying the seismic spring needs to replace the spring, it will indeed face a more cumbersome disassembly process. First, during disassembly, the motor equipment must be removed from the seismic bracket before accessing and handling the spring fixed on the annular seat. Since the motor equipment needs to be removed from the seismic bracket, this usually involves disassembling the electrical connection, mechanical interface and other supporting structures of the motor. The whole process is not only time-consuming, but also causes equipment downtime, affects the continuity of production or operation, and causes loss of production efficiency. The integrally formed structure of the annular seat limits the flexibility of disassembly, and the spring cannot be disassembled or replaced as quickly as a detachable component. Every time the spring is replaced, not only does it need to disassemble the equipment, but it is also necessary to handle the bolts, welding points or other fixing structures of the fixing seat, which greatly increases maintenance time and labor costs. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the top of the seismic spring of the seismic support in the prior art is usually fixed on an integrally formed annular seat. After long-term use, when the seismic support carrying the seismic spring needs to replace the spring, it will indeed face a more cumbersome disassembly process. First, during disassembly, the motor equipment must be removed from the seismic support before accessing and processing the spring fixed on the annular seat. Since the motor equipment needs to be removed from the seismic support, this usually involves disassembling the electrical connection, mechanical interface and other supporting structures of the motor. The whole process is not only time-consuming, but also causes equipment downtime, affects the continuity of production or operation, and causes a loss of production efficiency. The integrally formed structure of the annular seat limits the flexibility of disassembly, and the spring cannot be disassembled or replaced as quickly as a detachable component.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The main structure of the present invention includes a mounting plate, a support plate, a center column and an anti-seismic spring mounting plate for installing motor equipment, and a quick-release assembly is provided at the bottom of the mounting plate. The quick-release assembly replaces the traditional one-piece annular seat to fix the top of the anti-seismic spring, but the quick-release assembly can quickly remove the anti-seismic spring without removing the motor equipment on the top of the mounting plate, which significantly improves the maintenance efficiency. Unlike the traditional design that requires the motor equipment to be disassembled before the anti-seismic spring can be replaced, the quick-release assembly of the present invention allows the spring to be quickly replaced without disassembling the motor equipment, thereby effectively reducing the equipment downtime and maintenance costs. This design not only simplifies the disassembly process and reduces operational risks, but also improves the safety and convenience of equipment maintenance, making the replacement of the anti-seismic spring more efficient and flexible. Overall, the quick-release assembly optimizes the maintenance process, improves the operating efficiency of the equipment, and reduces production losses. It is particularly suitable for equipment that requires frequent maintenance.

[0016] 2. The present invention additionally provides a temporary support component at the quick-release component at the bottom of the mounting plate. When the quick-release component releases the anti-vibration spring, the anti-vibration spring and its accessories cannot support a certain position at the bottom of the mounting plate where the motor equipment is installed. The temporary support component can temporarily support the mounting plate after the spring is released to maintain its stability. The temporary support component provides additional support force to ensure that the mounting plate is not affected by uneven external force during the spring removal process, thereby preventing damage to the mounting plate or structural deformation due to lack of support. This design plays a key transitional role in the spring replacement process, not only improving the safety of the operation, but also avoiding additional maintenance costs caused by insufficient support, ensuring that the equipment remains stable and reliable during the removal and reinstallation process.

[0017] 3. The present invention provides a redundant locking assembly on the side of the quick-release assembly. When the temporary support assembly is in a vertical state, the quick-release assembly will control the redundant locking assembly while separating from the anti-seismic spring so that the temporary support assembly can maintain a state of continuous and stable support for the mounting plate. When the quick-release assembly is separated from the anti-seismic spring, the temporary support assembly can continuously and stably support the mounting plate. The redundant locking assembly can effectively prevent the temporary support assembly from loosening or shifting in the absence of spring support, ensuring that the mounting plate remains stable during the disassembly process, and avoiding deformation or damage caused by unstable support. This design not only enhances the safety of the disassembly process, but also improves the accuracy of the operation, prevents the occurrence of accidents, ensures the stability and reliability of the equipment during maintenance, and further improves the maintenance efficiency and service life of the equipment.

[0018] 4. The present invention is provided with a safety component on the side of the mounting plate, which allows the quick-release component to be separated from the anti-seismic spring only after the temporary support component provides stable support to the mounting plate. The safety component provided on the side of the mounting plate of the present invention ensures that the quick-release component can be separated from the anti-seismic spring only after the temporary support component provides stable support to the mounting plate. This design greatly improves the safety of operation, because it prevents the spring from being removed when the mounting plate is not sufficiently supported, thereby avoiding deformation or damage to the mounting plate caused by insufficient support. The safety component ensures through mandatory prerequisites that the quick-release component will trigger the release operation only when the temporary support component is in a correctly supported state, avoiding the risk of incorrect operation or operating errors. This design ensures the stability and reliability of the equipment disassembly process, reduces the possibility of accidents, and ensures the safety of personnel and equipment during maintenance.

[0037] The quick-release assembly includes a fixed half ring 25, a bidirectional screw 23, a main vertical rod 21, and a horizontal seat 22. Extension rods 81 are fixedly arranged at both ends of the center tube 8. A center groove 220 is opened at the center position of the top of the horizontal seat 22.

[0038] Insertion grooves 171 are provided on both sides of the fixing ring 17 at positions corresponding to the extension rod 81.

The redundant locking assembly includes a horizontal rod 20, a secondary vertical rod 19, a common plate 18, and an auxiliary column 181. A horizontal rod 20 is fixedly arranged on the top of the side of the main vertical rod 21.

The top cover 24 is threaded into the top of the extension tube 84.

[0041] A flip turbine 11 is fixedly provided on the side of one of the driving gears 12, and a driving worm 13 is screwed into the top of the flip turbine 11, and the end of the driving worm 13 is rotatably connected to the side of the closing cover 16, and a driving wheel 131 is fixedly provided at the end of the driving worm 13. A secondary vertical rod 19 is fixedly connected to the other end of the horizontal rod 20, and a common plate 18 is fixedly connected to the bottom of the secondary vertical rod 19.

Auxiliary holes 92 with the same diameter as the auxiliary columns 181 are opened on the side of the vertical seat 9 and the bottom of the side of the driven gear 10. When the auxiliary column 181 is inserted into the auxiliary hole 92 on the side of the driven gear 10, the rotation of the support leg 27 can be limited.

[0042] An avoidance groove 810 is provided at the top of the extension rod 81, and the secondary vertical rod 19 passes through the avoidance groove 810. The safety component includes a horizontal column 29, an interlocking half disk 26, and a locking groove 28. The center position of the side of the driving gear 12 is fixedly connected to one end of the horizontal column 29, and an interlocking half disk 26 is fixedly provided on the outer wall of the other end of the horizontal column 29. A locking groove 28 is provided on the top of the side of the interlocking half disk 26, and the side cross-sectional size of the locking groove 28 is the same as the side cross-sectional size of the common plate 18. The outer wall of the bidirectional screw 23 is symmetrically provided with external threads of opposite rotation directions, and a nut is fixedly provided in the middle position of the bidirectional screw 23. A gap is left between the bottom of the nut fixed in the middle position of the bidirectional screw 23 and the top of the center groove 220.

The anti-seismic spring 5 is movably sleeved on the outer wall of the center column 6, and the bottom of the anti-seismic spring 5 overlaps the top of the support shoulder 71.

[0043] It should be supplemented that the height of the extension tube 84 needs to be set high enough so that when the bottom of the central column 6 is separated from the bottom tube 7 , the central column 6 can be moved up to a sufficient position to separate the central column 6 from the anti-seismic spring 5 .

[0044] The specific implementation steps and principles of the present invention are as follows: When the entire seismic bracket is in normal working condition, the four groups of seismic springs 5 ​​are in normal working condition. At this time, the supporting legs 27 at the corresponding positions are in a horizontal state. At this time, since the locking grooves 28 and the common plate 18 are in an interlaced state, the lateral movement of the common plate 18 will be blocked, and the user cannot use a wrench to turn the nut in the middle position of the bidirectional screw 23 to drive the two fixed half rings 25 to approach each other, so that the head of the seismic spring 5 is separated from the two fixed half rings 25.

[0045] When it is necessary to replace the anti-seismic spring 5 at any position at the bottom of the mounting plate 1, human power rotates the driving wheel 131, and the driving wheel 131 drives the paired supporting legs 27 to a vertical state through the active worm 13, the flip turbine 11, the active gear 12, the driven gear 10, and the common shaft 121. At this time, the locking groove 28 is aligned with the common plate 18, and the user cannot use a wrench to rotate the nut in the middle position of the two-way screw 23, thereby driving the two fixed half rings 25 to approach each other, so that the head of the anti-seismic spring 5 is separated from the two fixed half rings 25, and the bottom bolt 14 is unscrewed from the bottom hole 61, and finally the center column 6 is separated from the bottom tube 7, and the center column 6 is moved up to the extreme position along the extension tube 84, so that the center column 6 is separated from the anti-seismic spring 5, and finally the auxiliary column 181 on the side of the common plate 18 enters into the docking plate 9, and is inside the auxiliary hole 92 opened on the side of the driven gear 10.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
