Description
Technical Field
[0001] The present application relates to the technical field of power distribution equipment, and in particular to a shock absorbing structure of an electric control box. Background Art
[0002] An electric control box is a box containing a variety of electrical equipment, used to achieve specific electrical control functions. It usually contains switches, circuit breakers, contactors, relays, PLC (Programmable Logic Controller) and other equipment, used for centralized control, protection and signal transmission of electrical systems. Electric control boxes are widely used in industrial automation, construction, energy, transportation and other fields to ensure the safe, stable and efficient operation of electrical systems.
[0003] At present, the electric control box in the factory is usually placed directly on the ground or bolted to the wall. When the production equipment in the factory is working, the motor will cause the production equipment to vibrate. The vibration will be transmitted to the electric control box through the ground. The switches and other equipment in the electric control box will vibrate along with the electric control box. Long-term vibration will cause the controller and other equipment in the electric control box to loosen. For example, the PLC (programmable logic controller) may be damaged during the vibration, causing errors in the production equipment in the factory, which will affect the normal operation of the production equipment in the factory. There are deficiencies. Utility Model Content
[0004] In order to improve the problem that the electric control box is affected by external vibrations, the present application provides a shock absorbing structure for the electric control box.
[0005] The present application provides an electric control box shock absorbing structure adopting the following technical solution:
[0006] A shock absorbing structure for an electric control box comprises a bottom plate and a top plate, wherein the bottom plate is arranged on the ground, and the electric control box is arranged on the top plate, and a longitudinal shock absorbing assembly and a transverse shock absorbing assembly for shock absorption are arranged between the bottom plate and the top plate, and the longitudinal shock absorbing assembly comprises a lower shell arranged on the bottom plate and an upper shell arranged on the top plate, a main shaft rod is arranged on the upper shell, and the main shaft rod slides through the lower shell, and an airbag ring is arranged between the upper shell and the lower shell.
[0007] By adopting the above technical solution, workers first fix the bottom plate on the factory floor, and then fix the electric control box on the top plate. When the vibration in the factory is transmitted to the bottom plate, the lateral vibration force transmitted to the bottom plate is weakened by the lateral shock-absorbing assembly. The force in the longitudinal direction on the bottom plate causes the upper shell to squeeze the lower shell. The main shaft rod limits the lateral movement of the upper shell, and the airbag ring is compressed. The reaction force of the compressed airbag ring slows down the force of the upper shell squeezing the lower shell. The electric control box on the top plate is damped in two directions, which helps to reduce the possibility of the electric control box being affected by external vibrations.
[0008] Optionally, a pressing cylinder is arranged between the lower shell and the bottom plate, the interior of the pressing cylinder is hollow and open toward one end of the lower shell, the main shaft rod slides through one end of the lower shell and extends into the pressing cylinder, a buffer plate is slidably arranged in the pressing cylinder along its axial direction, and the circumferential outer side wall of the buffer plate is in close contact with the inner side wall of the pressing cylinder.
[0009] By adopting the above technical solution, when the upper shell is pressed against the lower shell, the main shaft rod drives the buffer plate to squeeze the gas at the bottom of the pressure cylinder. The gas in the pressure cylinder is compressed, reducing the descending speed of the upper shell, thereby reducing the vibration amplitude of the top plate and further reducing the vibration of the electric control box in the longitudinal direction.
[0010] Optionally, the lateral shock absorbing assembly includes a plurality of vertical plates arranged on the bottom plate, a plurality of the vertical plates are arranged around the top plate, a rotating shaft is rotatably arranged on the vertical plate, a winding wheel is coaxially sleeved on the rotating shaft, a torsion spring is arranged between the winding wheel and the vertical plate, a pull wire is wound around the winding wheel, and one end of the pull wire facing away from the winding wheel is arranged on the top plate, a balance plate is slidably arranged on the bottom plate, the pressure cylinder is arranged on the balance plate, a pull rope is wound around the rotating shaft, and one end of the pull rope facing away from the rotating shaft is arranged on the balance plate.
[0011] By adopting the above technical scheme, when vibration acts on the balancing board in the lateral direction, the balancing board slides laterally, the pull rope pulls the rotating shaft to rotate, and the sliding of the balancing board causes the torsion springs on both sides of the top plate to deform in opposite directions. The winding wheel on one side of the top plate releases the line, and the corresponding winding wheel on the other side reels the line. Under the continuous deformation of the torsion spring, the balancing board gradually stops sliding, and at the same time, the electric control box on the top plate also stops moving laterally, thereby reducing the vibration sliding distance of the electric control box in the lateral direction.
[0012] Optionally, an energy-absorbing shaft is rotatably arranged on the vertical plate, a synchronous belt is wound between the energy-absorbing shaft and the rotating shaft, a friction wheel is coaxially arranged on the energy-absorbing shaft, a friction plate is arranged on the bottom plate, and the friction plate abuts against the friction wheel.
[0013] By adopting the above technical solution, when the rotating shaft rotates in the forward direction, the rotating shaft drives the energy-absorbing shaft to rotate through the synchronous belt, and the energy-absorbing shaft drives the friction wheel to rotate, and rotational friction occurs between the friction wheel and the friction plate. When the rotating shaft rotates in the reverse direction, rotational friction occurs between the friction wheel and the friction plate again, thereby continuously consuming the vibration energy of the electric control box in the lateral direction, which is beneficial to maintaining the stability of the electric control box.
[0014] Optionally, a hose is connected between the bottom of the pressing cylinder and the airbag ring.
[0015] By adopting the above technical solution, when the buffer plate squeezes the gas at the bottom of the pressure cylinder, the gas in the pressure cylinder flows into the airbag ring through the hose, increasing the gas pressure in the airbag ring, which is beneficial to further reduce the speed at which the upper shell presses on the lower shell.
[0016] Optionally, an elastic membrane is provided between the lower shell and the upper shell.
[0017] The adoption of the technical solution is helpful to reduce the possibility that the airbag ring expands outside the lower shell and the upper shell when the airbag ring is squeezed.
[0018] Optionally, the cross-sections of the upper shell and the lower shell are both C-shaped.
[0019] By adopting the above technical solution, it is helpful to reduce the space between the upper shell and the lower shell when the airbag ring is not compressed, which plays a protective role on the airbag ring.
[0020] Optionally, a wear-resistant layer is provided on the friction plate, and the wear-resistant layer is used to abut against the friction wheel.
[0021] The adoption of the above technical solution is helpful to reduce the possibility of workers frequently replacing friction plates and reduce the tediousness of workers' daily work.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The worker first fixes the bottom plate on the factory floor, and then fixes the electric control box on the top plate. When the vibration in the factory is transmitted to the bottom plate, the lateral vibration force transmitted to the bottom plate is weakened by the lateral shock-absorbing assembly. The longitudinal force on the bottom plate causes the upper shell to squeeze the lower shell. The spindle rod limits the lateral movement of the upper shell, and the airbag ring is compressed. The reaction force of the compressed airbag ring slows down the force of the upper shell squeezing the lower shell. The electric control box on the top plate is damped in two directions, which is conducive to reducing the possibility of the electric control box being affected by external vibrations.
[0024] 2. When the vibration acts on the balancing board in the lateral direction, the balancing board will slide laterally, the pull rope will pull the rotating shaft to rotate, and the sliding of the balancing board will cause the torsion springs on both sides of the top plate to deform in opposite directions. The winding wheel on one side of the top plate will release the line, and the corresponding winding wheel on the other side will reel it in. Under the continuous deformation of the torsion spring, the balancing board will gradually stop sliding, and the electric control box on the top plate will also stop moving laterally, thereby reducing the vibration sliding distance of the electric control box in the lateral direction;
[0025] 3. When the shaft rotates forward, the shaft drives the energy-absorbing shaft to rotate through the synchronous belt, and the energy-absorbing shaft drives the friction wheel to rotate, and rotational friction occurs between the friction wheel and the friction plate. When the shaft rotates reversely, rotational friction occurs between the friction wheel and the friction plate again, thereby continuously consuming the vibration energy of the electric control box in the lateral direction, which is beneficial to maintaining the stability of the electric control box.

[0029] The following is combined with Figure 1-2 This application is described in further detail.
[0030] The embodiment of the present application discloses a shock absorbing structure of an electric control box.
[0031] Reference Figure 1 A shock absorbing structure of an electric control box includes a bottom plate 2 and a top plate 3, the bottom plate 2 is bolted to the ground, the electric control box 1 is bolted to the top plate 3, and a longitudinal shock absorbing component 4 and a transverse shock absorbing component 5 for shock absorption are arranged between the bottom plate 2 and the top plate 3.
[0032] Reference Figure 1 and Figure 2 The longitudinal shock absorbing assembly 4 includes a lower shell 41 welded to the bottom plate 2 and an upper shell 42 welded to the top plate 3. The cross-sections of the upper shell 42 and the lower shell 41 are both C-shaped. A vertical main shaft rod 43 is welded to the upper shell 42. The main shaft rod 43 slides through the lower shell 41. An airbag ring 44 is arranged between the upper shell 42 and the lower shell 41. An elastic membrane 13 is bonded between the lower shell 41 and the upper shell 42. The airbag ring 44 is located in the circle of the elastic membrane 13.
[0033] Reference Figure 1 and Figure 2 A vertical pressing cylinder 6 is arranged between the lower shell 41 and the bottom plate 2. The interior of the pressing cylinder 6 is hollow and open at one end facing the lower shell 41. There is a gap between the main shaft rod 43 and the lower shell 41. The main shaft rod 43 slides through one end of the lower shell 41 and extends into the pressing cylinder 6. A buffer plate 7 is arranged in the pressing cylinder 6 to slide along its axial direction. A sealing ring 15 is sleeved on the circumferential outer wall of the buffer plate 7. The sealing ring 15 is tightly attached to the inner wall of the pressing cylinder 6. A hose 12 is connected between the bottom of the pressing cylinder 6 and the airbag ring 44.
[0034] When the vibration of the factory floor is transmitted to the base plate 2, the vibration causes the upper shell 42 to squeeze the lower shell 41 in the longitudinal direction of the base plate 2, and under the limiting action of the main shaft rod 43, the airbag ring 44 is compressed. The reaction force of the compressed airbag ring 44 slows down the speed at which the upper shell 42 squeezes the lower shell 41. At the same time, the main shaft rod 43 drives the buffer plate 7 to squeeze the gas at the bottom of the pressure cylinder 6.
[0035] The gas in the pressure cylinder 6 is compressed and flows into the airbag ring 44 through the hose 12, so that the gas pressure in the airbag ring 44 is further increased, and the airbag ring 44 expands to support the elastic membrane 13. The elastic membrane 13 is deformed and restricts the expansion of the airbag ring 44 in the lateral direction, so that the airbag ring 44 supports the upper shell 42, further slowing down the speed at which the upper shell 42 presses on the lower shell 41, thereby reducing the vertical movement distance of the electrical control box 1 on the top plate 3.
[0036] Reference Figure 1 and Figure 2 The lateral shock absorbing assembly 5 includes a balancing plate 56 slidably arranged on the bottom plate 2, the pressure cylinder 6 is welded to the balancing plate 56, a pull rope 57 is wound around the rotating shaft 52, and one end of the pull rope 57 facing away from the rotating shaft 52 is tied to the balancing plate 56, a plurality of vertical plates 51 are welded on the bottom plate 2, and the plurality of vertical plates 51 are evenly distributed around the top plate 3, the vertical plates 51 are rotatably connected with the rotating shaft 52, a winding wheel 53 is coaxially sleeved on the rotating shaft 52, a torsion spring 54 is arranged between the winding wheel 53 and the vertical plate 51, the torsion spring 54 is sleeved on the rotating shaft 52, a pull wire 55 is wound around the winding wheel 53, and one end of the pull wire 55 facing away from the winding wheel 53 is tied to the top plate 3.
[0037] Reference Figure 1 and Figure 2 An energy-absorbing shaft 8 is rotatably connected to the vertical plate 51, and the axis of the energy-absorbing shaft 8 is parallel to the axis of the rotating shaft 52. Synchronous wheels 16 are welded to both the energy-absorbing shaft 8 and the rotating shaft 52. A synchronous belt 9 is wound between the synchronous wheels 16 on the energy-absorbing shaft 8 and the synchronous wheels 16 on the rotating shaft 52. A friction wheel 10 is coaxially welded to the energy-absorbing shaft 8, and a friction plate 11 is welded to the bottom plate 2. The friction plate 11 is made of elastic metal material, and a wear-resistant layer 14 is bonded to the friction plate 11, and the wear-resistant layer 14 is pressed against the friction wheel 10 by the friction plate 11.
[0038] In the lateral direction of the bottom plate 2, the vibration causes relative slippage between the balance plate 56 and the bottom plate 2. The balance plate 56 drives the rotating shaft 52 to rotate through the pull rope 57. The sliding of the balance plate 56 causes the deformation directions of the torsion springs 54 on the opposite sides of the top plate 3 to be opposite, so that the winding wheel 53 on one side of the top plate 3 releases the pull wire 55, and the winding wheel 53 on the other side corresponding to it winds up the pull wire 55.
[0039] At the same time, the synchronous wheel 16 on the rotating shaft 52 drives the synchronous wheel 16 on the energy-absorbing shaft 8 to rotate through the synchronous belt 9, and the energy-absorbing shaft 8 drives the friction wheel 10 to rotate, and rotational friction occurs between the friction wheel 10 and the friction plate 11. When the torsion spring 54 recovers its deformation, rotational friction occurs between the friction wheel 10 and the friction plate 11 again until the balance plate 56 gradually stops sliding, and then the electric control box 1 on the top plate 3 stops moving in the lateral direction, thereby reducing the impact of vibration on the equipment in the electric control box 1 in the lateral direction.
[0040] The implementation principle of the shock-absorbing structure of an electric control box in an embodiment of the present application is as follows: when the vibration of the factory floor is transmitted to the base plate 2, in the longitudinal direction of the base plate 2, the vibration causes the upper shell 42 to squeeze the lower shell 41, and under the limiting action of the main shaft rod 43, the airbag ring 44 is compressed. The reaction force of the compressed airbag ring 44 slows down the speed at which the upper shell 42 squeezes the lower shell 41, and at the same time, the main shaft rod 43 drives the buffer plate 7 to squeeze the gas at the bottom of the pressure cylinder 6.
[0041] The gas in the pressure cylinder 6 is compressed and flows into the airbag ring 44 through the hose 12, so that the gas pressure in the airbag ring 44 is further increased, and the airbag ring 44 expands to support the elastic membrane 13. The elastic membrane 13 is deformed and restricts the expansion of the airbag ring 44 in the lateral direction, so that the airbag ring 44 supports the upper shell 42, further slowing down the speed at which the upper shell 42 presses on the lower shell 41, thereby reducing the vertical movement distance of the electrical control box 1 on the top plate 3.
[0042] In the lateral direction of the bottom plate 2, the vibration causes relative slippage between the balance plate 56 and the bottom plate 2. The balance plate 56 drives the rotating shaft 52 to rotate through the pull rope 57. The sliding of the balance plate 56 causes the deformation directions of the torsion springs 54 on the opposite sides of the top plate 3 to be opposite, so that the winding wheel 53 on one side of the top plate 3 releases the pull wire 55, and the winding wheel 53 on the other side corresponding to it winds up the pull wire 55.
[0043] At the same time, the synchronous wheel 16 on the rotating shaft 52 drives the synchronous wheel 16 on the energy-absorbing shaft 8 to rotate through the synchronous belt 9, and the energy-absorbing shaft 8 drives the friction wheel 10 to rotate, and rotational friction occurs between the friction wheel 10 and the friction plate 11. When the torsion spring 54 recovers its deformation, rotational friction occurs between the friction wheel 10 and the friction plate 11 again until the balance plate 56 gradually stops sliding, and then the electric control box 1 on the top plate 3 stops moving in the lateral direction, thereby reducing the impact of vibration on the equipment in the electric control box 1 in the lateral direction.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
