Description

Technical Field

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

[0002] Electromechanical equipment is a general term for the machinery, devices, and facilities needed by people in production and daily life. During operation, the interaction of internal parts and components of electromechanical equipment generates specific vibration frequencies. Continuous or severe vibration can easily cause problems such as loose bolts, loose mechanical connections, and accelerated wear of mechanical parts, affecting the normal operation and lifespan of the equipment. Therefore, anti-vibration supports are typically installed between the electromechanical equipment and the workbench during installation to address these issues.

[0003] Chinese utility model patent CN221704292U discloses a seismic-resistant bracket for electromechanical equipment, comprising a bracket body, multiple second seismic dampers fixedly connected to the bottom of the bracket body, and a common base plate fixedly connected to the bottom ends of the multiple second seismic dampers. Two square protrusions are fixedly connected to the top of the bracket body, and a mounting plate is attached to the bottom of the bracket body. Two connecting plates are fixedly connected to the top of the mounting plate, and a mounting block is fixedly connected to the top of the base plate. First seismic dampers are fixedly connected to both sides of the mounting block and between the two adjacent sides of the two connecting plates, with two first seismic dampers penetrating both sides of the bracket body. The bracket body is U-shaped, with multiple mounting holes at its bottom. These mounting holes allow for mounting onto other objects using screws and nuts. A motor is placed on the bracket body between two second straight slots or between a first straight slot and mounted using screws and nuts. This device is simple to use; the multiple first and second seismic dampers work together to significantly reduce motor vibration, achieving a seismic-resistant effect.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the above-mentioned solution, the support body is a U-shaped support with an overall opening facing downwards. The top of the support body is directly connected to the electromechanical equipment via bolts, and the bottom is directly connected to the building via bolts. Two first seismic dampers and multiple second seismic dampers are set inside the U-shaped opening of the support body to offset the vibration generated by the electromechanical equipment. However, in actual operation, the vibration generated by the electromechanical equipment can also be directly transmitted to the building through the side plates on both sides of the support body, resulting in an insignificant vibration reduction effect. This can easily cause problems such as loose bolts in the electromechanical equipment, loose mechanical connections, and accelerated wear of mechanical parts, thereby affecting the normal operation of the electromechanical equipment. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an anti-seismic bracket for the installation of electromechanical equipment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a seismic brace for installing electromechanical equipment, comprising a base plate, a support plate, and a mounting plate arranged at intervals from bottom to top; a first seismic component for vertical vibration reduction is provided between the base plate and the support plate; a fixing block is provided in the center of the top surface of the support plate; four vertical plates are provided protruding downwards from the bottom surface of the mounting plate around the fixing block; a second seismic component is provided between the four vertical plates and the corresponding sides of the fixing block; the second seismic component includes a connecting rod, a tie rod, and a mounting base; one end of the connecting rod passes through... The mounting base is rotatably connected to the upright plate via a first rotating shaft, and rotatably connected to one end of the pull rod via a second rotating shaft. The mounting base is rotatably connected to the corresponding side of the fixing block via a third rotating shaft. The second rotating shaft is arranged parallel to the first rotating shaft, and the third rotating shaft is arranged perpendicular to the first rotating shaft. The mounting base has a piston groove with an opening smaller than the cavity at the end away from the fixing block. The pull rod has a piston rod at the end away from the connecting rod. A sliding block is slidably disposed in the piston groove cavity at the end of the piston rod. A first compression spring is disposed between the sliding block and the opening of the piston groove.

[0007] By adopting the above technical solution, a first anti-vibration component is set between the base plate and the support plate to reduce vertical vibration of the electromechanical equipment. Then, by setting a fixing block, a mounting plate, and four vertical plates, and setting a second anti-vibration component between the corresponding sides of the four vertical plates and the fixing block, the electromechanical equipment is reduced horizontally by the four sets of second anti-vibration components. The electromechanical equipment is mounted on the mounting plate. The vibration generated by the electromechanical equipment is reduced significantly by passing through the second anti-vibration components and then through the first anti-vibration components, thus achieving an anti-vibration effect. This can effectively reduce problems such as loose bolts, loose mechanical connections, and accelerated wear of mechanical parts caused by the vibration of the electromechanical equipment, and ensure the normal operation of the electromechanical equipment.

[0008] Furthermore, the first anti-seismic component includes two fixed plates spaced apart on the base plate. Two wedges are slidably disposed between the two fixed plates on the base plate. The inclined surfaces of the two wedges are opposite each other, and the top surface is smaller than the bottom surface. A second compression spring is connected between the wedges and the fixed plates. A boss is provided on the bottom surface of the support plate. The boss slides in contact with the inclined surfaces of the two wedges. A guide block is provided on the base plate below the boss. A guide groove is provided on the guide block. A lifting rod is provided at the bottom of the boss. The lifting rod and the guide groove form a sliding guide engagement. A third compression spring is sleeved on the guide block. One end of the third compression spring is fixedly connected to the top surface of the base plate, and the other end is fixedly connected to the bottom of the boss.

[0009] By adopting the above technical solution, a fixed plate, a wedge block, a boss, a guide block, and a lifting rod are set up. The second compression spring generates an inward thrust on the wedge block, which in turn generates an upward thrust on the boss. At the same time, the third compression spring is sleeved on the guide block and also generates an upward thrust on the boss, thus supporting the support plate and the components above the support plate. Meanwhile, the vibration generated by the electromechanical equipment is transmitted to the second and third compression springs to eliminate vertical vibration.

[0010] Furthermore, a first guide hole is provided on the fixed plate, and a guide rod is provided on the side of the wedge block near the corresponding fixed plate. The guide rod and the first guide hole form a sliding guide fit. The second compression spring is sleeved on the guide rod, with one end of the second compression spring fixedly connected to the fixed plate and the other end fixedly connected to the wedge block.

[0011] By adopting the above technical solution, a first guide hole and a guide rod are set, and the second compression spring is sleeved on the guide rod to guide and fix the second compression spring.

[0012] Furthermore, the inner ring of the piston groove is provided with a first sealing ring that fits against the piston rod, and the outer side of the sliding block is provided with a second sealing ring that fits against the piston groove wall. Two opposing stepped holes are horizontally opened on the sliding block on the outer periphery of the sliding rod. The piston groove is injected with buffer solution that covers the two stepped holes. A ball is provided in the larger diameter section of the stepped hole, and the diameter of the ball is larger than the diameter of the smaller diameter section of the stepped hole.

[0013] By adopting the above technical solution, a first sealing ring, a second sealing ring, a stepped hole, and a ball bearing are set up. The injection of buffer solution into the piston groove can counteract the repeated vibration of the first compression spring due to its own elasticity. The ball bearing is set in the large-diameter section of the stepped hole, and the diameter of the ball bearing is larger than the diameter of the small-diameter section of the stepped hole. By moving the ball bearing in the large-diameter section of the stepped hole, the port of the small-diameter section is blocked. When the sliding block moves, it squeezes the buffer solution on one side. When the buffer solution is squeezed, it generates a reverse thrust on the sliding block, thereby playing a buffering role.

[0014] Furthermore, a limiting rod is provided in the large-diameter section of the stepped hole. The limiting rod is located on the side of the ball away from the small-diameter section of the stepped hole. A fourth compression spring is provided between the limiting rod and the ball. One end of the fourth compression spring is fixedly connected to the limiting rod, and the other end is fixedly connected to the ball.

[0015] By adopting the above technical solution, a limit rod and a fourth compression spring are set. The fourth compression spring applies a pushing force to the ball in the direction of the small diameter section of the stepped hole, ensuring that the ball can quickly return to its original position when the sliding block changes its movement direction.

[0016] Furthermore, guide posts are provided around the base plate, and second guide holes corresponding to the positions of the guide posts are opened around the support plate. The guide posts and the second guide holes form a sliding guide fit.

[0017] By adopting the above technical solution, guide posts and second guide holes are set. The sliding guide cooperation between the guide posts and the second guide holes limits and guides the support plate, ensuring that the horizontal position of the support plate relative to the bottom plate is fixed.

[0018] Furthermore, the mounting plate is provided with a plurality of strip-shaped holes spaced apart, the strip-shaped holes being used for mounting electromechanical equipment.

[0019] By adopting the above technical solution, several strip holes are set to fix different electromechanical equipment.

[0020] Furthermore, mounting holes are provided around the base plate for mounting the base plate onto the building.

[0021] By adopting the above technical solution, mounting holes are provided for fixing the base plate to the building.

[0022] In summary, this utility model has the following beneficial effects:

[0023] In this application, a first anti-vibration component is installed between the base plate and the support plate to vertically dampen the electromechanical equipment. Then, a fixing block, a mounting plate, and four upright plates are installed. A second anti-vibration component is installed between the corresponding sides of the four upright plates and the fixing block. The four sets of second anti-vibration components dampen the electromechanical equipment horizontally. The electromechanical equipment is installed on the mounting plate. The vibration generated by the electromechanical equipment is reduced significantly by passing through the second anti-vibration component and then through the first anti-vibration component, thus achieving an anti-vibration effect. This can effectively reduce problems such as loose bolts, loose mechanical connections, and accelerated wear of mechanical parts caused by the vibration of the electromechanical equipment, allowing the electromechanical equipment to operate normally.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-6 As shown in the illustration, this application discloses a seismic-resistant bracket for installing electromechanical equipment, comprising a base plate 10, a support plate 20, and a mounting plate 30 arranged at intervals from bottom to top. A first seismic-resistant component 40 is disposed between the base plate 10 and the support plate 20 for vertical vibration damping of the electromechanical equipment. A fixing block 21 is disposed in the center of the top surface of the support plate 20, and four vertical plates 31 are disposed on the bottom surface of the mounting plate 30 protruding downward around the fixing block 21. A second seismic-resistant component 50 is disposed between the four vertical plates 31 and the corresponding sides of the fixing block 21. When the electromechanical equipment is mounted on the mounting plate 30, the vibration generated by the electromechanical equipment is significantly reduced through the second seismic-resistant component 50 and the first seismic-resistant component 40, thereby achieving a seismic-resistant effect. This effectively reduces problems such as loose bolts, loose mechanical connections, and accelerated wear of mechanical parts caused by the vibration of the electromechanical equipment, ensuring the normal operation of the electromechanical equipment.

[0033] In its specific configuration, the first anti-seismic component 40 includes a fixed plate 41, wedges 42, a boss 22, a guide block 44, and a lifting rod 46. There are two fixed plates 41, spaced apart on the base plate 10. Two wedges 42 are slidably disposed on the base plate 10 between the two fixed plates 41. The inclined surfaces of the wedges 42 face each other, with the top surface smaller than the bottom surface. A second compression spring 43 connects the wedges 42 to the fixed plates 41, with one end of the second compression spring 43 fixedly connected to the fixed plate 41 and the other end fixedly connected to the wedges 42. The boss 22 is disposed on the bottom surface of the support plate 20, and slides in contact with the inclined surfaces of the two wedges 42. The vertical vibration generated by the electromechanical equipment is converted into a horizontal force through the interaction of the boss 22 and the two wedges 42, compressing the second compression spring 43 to reduce vibration. Specifically, a first guide hole 48 is provided on the fixed plate 41, and a guide rod 49 is provided on the side of the wedge block 42 near the corresponding fixed plate 41. The guide rod 49 and the first guide hole 48 form a sliding guide engagement. A second compression spring 43 is sleeved on the guide rod 49 to guide and fix the second compression spring 43. A guide block 44 is provided on the base plate 10 and located below the boss 22. A guide groove 45 is provided on the guide block 44, and a lifting rod 46 is provided at the bottom of the boss 22. The lifting rod 46 and the guide groove 45 form a sliding guide engagement. A third compression spring 47 is sleeved on the guide block 44. One end of the third compression spring 47 is fixedly connected to the top surface of the base plate 10, and the other end is fixedly connected to the bottom of the boss 22. The vertical vibration generated by the electromechanical equipment is compressed by the boss 22 to further cancel the vertical vibration generated by the electromechanical equipment.

[0034] The second anti-seismic component 50 includes a connecting rod 51, a pull rod 52, and a mounting base 53. One end of the connecting rod 51 is rotatably connected to the upright plate 31 via a first rotating shaft 54, and the other end is rotatably connected to one end of the pull rod 52 via a second rotating shaft 55. The mounting base 53 is rotatably connected to the corresponding side of the fixing block 21 via a third rotating shaft 56. The end of the mounting base 53 away from the fixing block 21 has a piston groove 57 with an opening smaller than the groove cavity. The end of the pull rod 52 away from the connecting rod 51 is provided with a piston rod 58. The end of the piston rod 58 is provided with a sliding block 60 that is slidably disposed in the groove cavity of the piston groove 57. A first compression spring 59 is provided between the sliding block 60 and the opening of the piston groove 57. The horizontal vibration generated by the electromechanical equipment is damped by compressing the first compression spring 59. In practice, the second rotating shaft 55 is arranged parallel to the first rotating shaft 54, and the third rotating shaft 56 is arranged perpendicular to the first rotating shaft 54, so as to ensure that the second anti-seismic component 50 can rotate freely in both the vertical and horizontal directions, thereby ensuring that the piston rod 58 can always move along the direction of the piston groove 57.

[0035] Specifically, the inner ring of the piston groove 57 is provided with a first sealing ring 61 that fits against the piston rod 58, and the outer side of the sliding block 60 is provided with a second sealing ring 62 that fits against the groove wall of the piston groove 57, ensuring a good seal at the contact point between the piston rod 58 and the piston groove 57 and preventing leakage of the buffer solution. Two opposing stepped holes 63 are horizontally formed on the outer periphery of the sliding rod on the sliding block 60. A ball bearing 64 is installed in the larger diameter section of the stepped hole 63, and the ball bearing 64 is close to the smaller diameter section. The diameter of the ball bearing 64 is larger than the diameter of the smaller diameter section of the stepped hole 63, ensuring that the ball bearing 64 can block the smaller diameter section of the stepped hole 63, thereby controlling whether the buffer solution in the piston groove 57 can pass through the stepped hole 63. A limiting rod 65 is installed within the large-diameter section of the stepped hole 63, and the limiting rod 65 is located away from the small-diameter section. A fourth compression spring 66 is installed between the limiting rod 65 and the ball 64. One end of the fourth compression spring 66 is fixedly connected to the limiting rod 65, and the other end is fixedly connected to the ball 64. The fourth compression spring 66 applies a pushing force to the ball 64 in the direction of the small-diameter section of the stepped hole 63, ensuring that the ball 64 can quickly return to its original position when the sliding block 60 changes its movement direction. Furthermore, a buffer solution covering both stepped holes 63 is injected into the piston groove 57. The buffer solution can counteract the repeated vibration of the first compression spring 59 due to its own elasticity. When the sliding block 60 moves within the piston groove 57, it squeezes the buffer solution on one side. When the buffer solution is squeezed, it generates a reverse pushing force on the sliding block 60, thereby playing a buffering role. At the same time, the buffer solution is squeezed, and the buffer solution on the side with reduced space will flow to the side with increased space. The buffer solution enters the push-open ball 64 from the small diameter section of the stepped hole 63 and flows. The other step hole 63 ball 64 blocks the small diameter section in the large diameter section to prevent the buffer solution from flowing. By pushing open the ball 64, the fourth compression spring 66 is compressed, which further cancels the horizontal vibration generated by the electromechanical equipment.

[0036] Guide posts 11 are provided around the base plate 10, and second guide holes 23 corresponding to the positions of the guide posts 11 are provided around the support plate 20. The sliding guide cooperation between the guide posts 11 and the second guide holes 23 limits and guides the support plate 20, ensuring that the support plate 20 is fixed in a horizontal position relative to the base plate 10. Several strip holes 32 are provided on the mounting plate 30 at intervals to fix different electromechanical equipment. Mounting holes 12 are provided around the base plate 10 for fixing the base plate 10 to the building.

[0037] The operating principle of the seismic bracing for electromechanical equipment installation in this embodiment is as follows: The seismic bracing is placed on the building and installed on the building using bolts connected through mounting holes 12. The electromechanical equipment is then placed on the seismic bracing and installed on the seismic bracing using bolts connected through slotted holes 32. When the electromechanical equipment starts working, the vibrations generated by the equipment pass sequentially through the mounting plate 30, the second seismic component 50, the support plate 20, the first seismic component 40, and the base plate 10. When passing through the second seismic component 50, the second seismic component 50 dampens the horizontal vibrations generated by the electromechanical equipment. When passing through the first seismic component 40, the first seismic component 40 dampens the vertical vibrations generated by the electromechanical equipment. All the vibrations generated by the electromechanical equipment can pass through the second seismic component 50 and the first seismic component 40. This seismic bracing can effectively cancel out the vibrations generated by the electromechanical equipment, resulting in a significant seismic resistance effect.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
