Load locking and adjusting improved constant force spring support hanging bracket

Abstract

The invention discloses a load locking and adjusting improved constant force spring support hanging bracket. The load locking and adjusting improved constant force spring support hanging bracket comprises a front end plate, a spring cover barrel, an outer frame, a rotation frame, a pull rod, a spindle, a tail end plate, a spring pull rod, a guiding sleeve and a load adjusting nut. One side face of the front end plate is fixed to the end face of one end of the spring cover barrel, and the outer frame is fixed to the other side face of the front end plate. The end portion of the rotation frame is located in the outer frame. The spindle penetrates the outer frame and the rotation frame to connect the outer frame with the rotation frame. The tail end plate is located in the other end of the spring cover barrel. A spring is arranged in the spring cover barrel, one end of the spring pull rod is connected with the guiding sleeve, and the other end of the spring pull rod penetrates the outer frame and then penetrates the front end plate, the spring and the tail end plate to be connected with the load adjusting nut. The guiding sleeve and the rotation frame are connected through a load bolt. The support hanging bracket is convenient to lock, the load adjusting range is wide, and load adjustment is convenient.

Description

technical field [0001] The invention relates to a support and hanger, in particular to a load locking and adjustment improved constant force spring support and hanger. Background technique [0002] At present, the lever-type constant force spring support and hanger commonly used in the domestic electric power and petrochemical industries is manufactured according to the "Constant Force Spring Support and Hanger" JB / T 8130.1-1999 standard. After a period of operation, the outer frame plate and the rotary frame The four locking pin holes are generally not on the same axis. When performing pipeline hydraulic test, pipeline replacement and repair, and constant force spring hanger replacement, it is necessary to remove the four pins on the outer frame plate of the constant force spring hanger and the rotary frame in advance. Adjust the concentricity of the four locking pin holes, and then pass the locking pin through the above four locking pin holes to lock the constant force spr...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: 1) The constant force spring hanger is suspended at high altitude and the load generally reaches several tons or even tens of tons. It is extremely difficult to adjust the centers of the four locking pin holes of the constant force spring support The locking of the constant force support and hanger of the unit brings great difficulties; 2) The adjustment range of the output load is small (only ±10% can be adjusted through the load bolt). Difficult, even broken when forced to adjust
