Description
Technical field
The utility model relates to plant equipment, is specifically related to a kind of coal breaker damped platform.
Background technology
Coal breaker is widely used in the industries such as coal, power plant and metallurgy, is used for crushing lump coal to improve coal burning effect and to improve burn-off rate.Coal breaker can produce very big vibrations during work, in order to reduce the destructive power shaking to coal breaker fuselage and basis, shaken to reach to absorb by upper mounting plate, lower platform and the multiple damping springs being located between upper mounting plate and lower platform it is generally required to arrange one between coal breaker and its basis, reduce the purpose of vibration amplitude.The upper mounting plate of existing coal breaker damped platform is all directly to be welded into hollow structure by big block plate, manufacture is inconvenient, also steel are wasted, the intensity of deadweight and raising upper mounting plate in order to increase upper mounting plate, also need to pour into a mould concrete in the hollow cavity of upper mounting plate.But facts have proved, the simple deadweight improving upper mounting plate can not reduce the purpose of vibrations, excessive being accomplished by of upper mounting plate deadweight uses the higher damping spring of intensity, the intensity of damping spring is higher, restoring force is bigger, elastic deformation is more dumb, is unfavorable for playing to greatest extent the damping effect of damped platform.
Content of the invention
It is sufficiently high that the purpose of this utility model is to provide a kind of intensity, good damping effect, is conducive to the structural steel frame damp type sand launder playing the damping effect of damped platform to seal coal breaker damped platform.
Technical solution of the present utility model is: it includes upper mounting plate, lower platform and several damping springs being located between upper mounting plate and lower platform, on each spring base that the upper end of each damping spring is respectively supported on upper mounting plate, on each spring base that lower end is respectively supported on lower platform, upper mounting plate is to be provided with coal breaker feed opening by the side that steel welding is connected into, middle part is provided with reducing motor installation site, opposite side is provided with the frame structure of mounting position of motor, several dampers are not also had between upper mounting plate and lower platform, two connection ends of each damper are hinged with upper mounting plate and lower platform respectively.
Of the present utility model having the technical effect that uses it can effectively reduce the vibrations that coal breaker produces, and is conducive to protection coal breaker improve its service life and reduce parts damages rate, makes coal breaker reduce maintenance times to improve its operating efficiency.Its intensity is sufficiently high, do not need to pour into a mould concrete in upper mounting plate, good damping effect, owing to upper mounting plate deadweight is less, can select the damping spring that intensity is relatively smaller, the intensity of damping spring is less, and restoring force is less, elastic deformation is more flexible, is conducive to playing to greatest extent the damping effect of damped platform.It also have employed damper between upper mounting plate and lower platform simultaneously, advantageously in the damping effect strengthening damped platform, to reach to absorb the purpose of the vibrations of coal breaker and the produced destructive power of reduction vibrations.
Quality due to upper mounting plate only affects the equipoise of system, and namely only the quiet deformation to damping spring has an impact, and the size of damping spring restoring force is directly proportional (direction is contrary with displacement, points to equipoise all the time) with displacement.Spring strength diminishes, and its restoring force also reduces.This will be greatly prolonged equipment life (the especially life-span of coal breaker main shaft bearing), also extend the time between overhaul of equipment simultaneously.The effect increasing damper can be verified from the process of the dissipation of energy of vibrations, in conjunction with damping spring, just greatly strengthen the damping effect of coal breaker, greatly reduces maintenance cost and the operating cost of coal breaker simultaneously, is conducive to improving the profit of coal breaker.It was verified that using effect is preferable, coal breaker owner is very satisfied, produces a desired effect.
