The utility model adopts moment synthesis, compensation principle, utilizes the major and minor spring of housing, cam, roller composite structure to realize its function.Be provided with by housing the height that sedimentation protector to be locked in requirement by screw lock device when mounted, pipe support bottom be placed on loading plate, by pipe support top bolt fixing and locking after pipe laying, before putting into operation, fixing and locking device unlocked.
Preferably, be set with guide plate outside load pipe, guide plate is contained on housing, guarantees the vertical movement of load pipe.
Preferably, main spring bracket is provided with adjusting bolt, for regulating the load of main spring.
Preferably, auxiliary spring is provided with equalising torque controlling device, for regulating the carrying of auxiliary spring.
Preferably, be threaded connection between load pipe and loading plate, the height of adjustable loading plate.
Preferably, loading plate is provided with low friction pair, and pipe support does not increase additional stress to pipeline when moving horizontally.
Preferably, housing is provided with mobile instruction and observes scale, is convenient to observe displacement amount intuitively.
Preferably, cam is strip, and side is curved surface, coordinates with roll wheel assembly, and opposite side coordinates with equalising torque controlling device, and equalising torque controlling device is connected with auxiliary spring.
Preferably, pipe support is insulation pipe support, and existing insulation possesses again the function of support force.
Preferably, camshaft, cam, auxiliary spring and torque balance device are two groups and are arranged symmetrically with in housing, make stress yielding support more stable.
Working principle and process:
Support force acts directly on main spring by load pipe, load plate, auxiliary spring acts on load pipe by equalising torque controlling device, cam, roller, loading plate, and according to the change of main spring and the spring performance of auxiliary spring and the tracing pattern of cam and angle of swing, the moment of main spring and auxiliary spring be constantly change with joint efforts in running, act on support force on main spring and be constant by cam, auxiliary spring making a concerted effort of being formed.
When storage tank is because of earthquake with when there is foundation settlement, when pipeline is moved down with the roller in dynamic load pipe, load plate downwards by peak, reducing gradually with joint efforts of auxiliary spring, the power of main spring increases gradually, and it is made a concerted effort for the power of main spring deducts making a concerted effort of auxiliary spring.
When neutral position, bear load by main spring, making a concerted effort of auxiliary spring is zero.
When lower position, the direction of making a concerted effort of auxiliary spring is contrary with the resultant direction of main spring, acts on making a concerted effort for the power of main spring deducts making a concerted effort of auxiliary spring in load plate.
According to above principle, pipeline occurs to driving the load pipe of pipe sedimentation protector also to move down during bottom offset simultaneously, but is constant to the supporting force of pipeline.
The beneficial effect that the utility model is compared with prior art had is:
1. pipe sedimentation protector support force is 10KN-200KN, stroke 0-300mm, covers the whole possible needs of storage tank connecting tube.
2. support force is less than 3% in total travel change.
3. when installing, support force is adjustable within the specific limits.
4. be quick on the draw, during action, additional stress can not be produced to pipeline.
5. be incubated pipe support, prevent pipe self-energy from leaking, and meet the requirement of support force.
6. be incubated pipe support and can ensure moving horizontally when there is earthquake.
7. compact structure, volume is little, lightweight, easy for installation.
8. safe and reliable to operation, Long-Time Service is non-maintaining.
