Description

A kind of spring support hanging frame

Technical fieldThe utility model relates to a kind of supporting frame, relates in particular to a kind of spring support hanging frame.

Background techniqueSpring support hanging frame is mainly used in needing to reduce the place of displacement stress at present, such as body of power station boiler, the vapour of power station, water, the foil portions such as cigarette airduct and burner, and petrochemical equipment need to reduce the place of displacement stress with other, existing spring support hanging frame mainly is by cylindrical outer casing, upper cover plate, lower cover plate, suspension ring, spring, pressing plate, the load screw rod, spend blue nut and stop pin to form, shell upper, upper cover plate and lower cover plate are established respectively in lower two ends, the upper end of upper cover plate is provided with suspension ring, the spring coaxial with it established in the inside of shell, the spring inner axial direction is provided with a load screw rod radially, the upper end of load screw rod links to each other with the pressing plate that is located at the spring upper end, the lower end of load screw rod links to each other with spending blue nut, being provided with at lower cover plate can be for the through hole of tightening nut upper and lower displacement, and above-mentioned shell is provided with and plays the stop pin that limits pressing plate.

By the metal alloy cylindrical spring made of carbon steel, alloyed steel, Cuprum alloy or nickel alloy for example because existing spring support hanging frame adopts substantially, when as installed is used, because foreign impacts and spring itself can produce certain vibration, the vibration stress that produces not only exerts an influence to spring itself, and can produce certain impact to the equipment that connects on the suspension and support, this just easily causes the damage of equipment, has reduced the working life of equipment; In addition, existing spring support hanging frame is longer lower service time at the environment of humidity, and with the corrosion that may be accompanied by, the performance of spring can be affected through moisture.In addition, existing spring support hanging frame in use, owing to needing the difference of load displacement, need to select different spring support hanging frames, when the load that needs spring support hanging frame and displacement were larger, general Adopts measure was to increase the height of spring or the mode of connecting with two springs, had so not only increased the parameters such as size, weight of suspension and support itself, improve the difficulty of processing, and strengthened production cost and workman's labor intensity.

The model utility contentThe purpose of this utility model is to provide a kind of equipment and vibration stress of itself of not only reducing, and damping is good, and humidity, corrosion resistance are strong, the load and the load displacement that bear are larger, and processing is simple, and cost of production is low, long service life, the reliable spring support hanging frame of handling safety.

The utility model mainly includes shell, upper cover plate, lower cover plate, suspension ring, spring, pressing plate, the load screw rod, spend blue nut, stop pin and inner casing, its housing, upper cover plate, lower cover plate, suspension ring, pressing plate, spend blue nut and stop pin substantially same as the prior art, cylindrical outer casing upper, upper cover plate and lower cover plate are established respectively in lower two ends, the upper end of upper cover plate is provided with suspension ring, the spring coaxial with it established in the inside of shell, this spring is complex spring, to be it wrap up one deck rubber material composite sulfuration around metal coil spring forms, described spring inner axial direction is provided with a tubular inner casing coaxial with it, this inner casing is contour with spring and identical with the material of shell, the upper end welding pressing plate coaxial with it of inner casing, the diameter of this pressing plate equals the internal diameter of shell substantially, and namely spring is located between pressing plate and the lower cover plate; The inside axial direction of inner casing is provided with a load screw rod that is threaded connection with inner casing, namely establishes the internal thread corresponding with the load screw rod at the inwall of inner casing, and the load screw rod links to each other with inner casing by this internal thread; The lower end of described load screw rod links to each other with spending blue nut, and being provided with at described lower cover plate can be for the through hole of inner casing upper and lower displacement, and the diameter of this through hole equals the external diameter of inner casing substantially, and above-mentioned shell is provided with and plays the stop pin that limits pressing plate function.

The utility model spends blue nut stressed when work, drives load bolt, load bolt drives inner casing, and the pressing plate on the inner casing presses down, and brings corresponding displacement behind the Compress Spring, when if required load and displacement are inadequate, can be first just the load screw rod then spend blue nut stressed again by rotating partial distance in the inner casing, drive load bolt, load bolt drives inner casing, and the pressing plate on the inner casing presses down, and brings corresponding displacement behind the Compress Spring, in order to reach required displacement, thereby meet the demands.Spring of the present utility model adopts complex spring, because complex spring not only has good damping, can bear very large load, and have stronger humidity and a corrosion resistance, the vibration that foreign impacts and spring itself produces in the time of so just can reducing work, reduce the impact that spring itself produces, slow down the impact that the equipment that connects on the suspension and support is produced, thus the working life of increase equipment and suspension and support; The performance of spring can not be affected when in addition, existing spring support hanging frame used under the environment of humidity.

The utility model has also compared with prior art that processing is simple, and cost of production is low, long service life, the advantage such as handling safety is reliable.
