Spring type constant force support hanger

Abstract

The invention relates to a spring type constant force support hanger. The spring type constant force support hanger comprises a rotary frame and a fixed frame, the rotary frame is connected to the fixed frame through a main shaft, the rear end of the fixed frame is fixedly connected with a sleeve, the front end of the interior of the sleeve is provided with a tray plate, a pressure plate is arranged at the rear end in the sleeve, a spring located in the sleeve is arranged between the tray plate and the pressure plate, a pull rod is arranged in the sleeve, the pull rod penetrates through the pressure plate, the spring and the tray plate to be connected to the rotary frame, and the rear end of the pull rod is connected with a lock nut; and a rolling bearing in contact with the inner wall ofthe sleeve is arranged on the periphery of the rear end of the pressure plate, the rotary frame is provided with a load pull rod, and the other end of the load pull rod is connected with a tension nut. The spring type constant force support hanger is simple in structure, high in safety performance and long in service life; and the rolling bearing in contact with the inner wall of the sleeve is additionally arranged at the outer end of the pressure plate, friction between the pressure plate and the inner wall of the sleeve is effectively prevented, and normal expansion and contraction of the spring are ensured.

Description

technical field [0001] The invention relates to a constant force support and hanger, in particular to a spring type constant force support and hanger. Background technique [0002] The constant force spring hanger is designed according to the principle of moment balance. Under the allowable load displacement, the load moment and spring moment are always in balance. For pipelines and equipment supported by constant force spring hangers, when displacement occurs, it can provide a constant supporting force, so it will not bring additional stress to pipeline equipment. Constant force spring supports and hangers are generally used in places where displacement stress needs to be reduced, such as power plant boiler bodies, suspension parts such as steam, water, smoke, air pipes and burners in power plants, and such supports are required in petroleum and chemical industries. The place. [0003] The traditional constant force support and hanger includes elastic nuts, load pull rod...

Problems solved by technology

[0003] The traditional constant force support and hanger includes elastic nuts, load pull rods, fixed frames, springs and sleeves, etc. During use, the pressure plate in the sleeve is likely to rub against the inner wall of the sleeve during the movement process, and it is easy to get stuck, resulting in not working
