The arc-shaped curved surface of front end is applied on idler wheel, is adjusted the torque that load control bolt generates two power in the initial state and is kept
Balance, when piping displacement is downward, pipeline, which moves down, drives load frame together with idler wheel as pipeline moves downwardly together, at this time
Piping load is constant, and the arm of force is continued to increase with the movable length of idler wheel, and the torque generated around main shaft also continues to increase.At this time
The arm of force of spring is held essentially constant, and pushes slewing frame to rotate around the spindle when idler wheel moves down, spring is because of slewing frame
Rotation is compressed and spring force continues to increase, and the torque that spring generates also is continued to increase when idler wheel moves down, thus with
The torque continued to increase that piping load generates keeps balance.
When piping displacement is upward, load frame need to be pulled to lowermost position in advance, move up when pipeline work at this time, spring
Power is moved up by slewing frame pushing rolling wheels, with move down during on the contrary, the arm of force of piping load is with pipe at this time
Road constantly shifts up and constantly reduces, and torque also reduces simultaneously, and slewing frame moves up at this time, and amount of spring compression becomes smaller,
Spring force also becomes smaller therewith, and the torque generated by spring also constantly reduces simultaneously, to constantly reduce when upward with piping displacement
Torque keep balance.
The beneficial effects of the utility model are:
1. mounting height is greatly lowered, mounting height is common constant-force spring hanger under same load and misalignment
1/2 to 2/3.
2. output loads change in total travel less than 5%.
3. load is adjusted in a certain range after installation.
It, can be non-maintaining with longtime running 4. structure is simple, reliable for operation.
