After aircraft tail cylinder, under the guiding role of carrying roller, it is rolled into tubular automatically, two band edge laps overlap, material
It is enclosed in round tube, just arranges one group of carrying roller every a distance, be evenly distributed on around round tube, regular polygon is formed, to pipe
Shape band applies pressure appropriate, bears its weight, enables it to keep tubular, and can play the guiding role to tubular band, makes pipe
Shape band is run along linear or arc-shaped path.Before head discharging, under the guiding role of carrying roller, automatically open into flat
Shape unsnatches material, bypasses head drum, when returning at charging, can enclose into tubulose, be also possible to flat shape.
According to HG/T4224-2011 " steel cord core tubular conveyor belt " standard, lateral stiffness is tubular conveyor belt (following letter
Claim tubular band) important indicator, which is equally applicable to fabric core tubular conveyor belt.
It is carrying roller and with contact that current existing tubular band rigidity test macro, which uses, and contact surface has certain friction
Power, and circular pipe type conveyer carrying roller is varied, when calculating because frictional force difference is affected to calculated result.
Because tubular band is in turning by very big centripetal force, under the action of centripetal force, tubular band is easier to deform,
It will appear the case where collapsing pipe if tubular band insufficient rigidity when turning, when rigidity excessive straightway is easy for pipe conveyer occur
Because of resistance excessive the case where cannot operating, therefore the values of stiffness for testing tubular band when turning is very necessary.And current existing pipe
Normal forces when the rigid test macro of band can only test static state, and it is unable to the values of stiffness when turning of testing tube shape band.
Summary of the invention
The present invention to solve the above-mentioned problems, proposes a kind of tubular band lateral stiffness test macro, has used smooth
Stainless steel contact plate is contacted with band, is greatly reduced frictional force, is conducive to the acquisition of experimental data, and when experiment can rub with ignoring
Wiping power can ignore.And the variation in rigidity when operation turning of pipe band can be simulated, is increased and decreased by increasing the counterweight of lateral force
Power when turning solves the problems, such as that previous equipment can only test straightway pipe band rigidity.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of tubular band lateral stiffness test macro disclosed in one or more embodiments, comprising: horizontal segment is rigid
Property test macro and turnaround section rigidity test macro；
The horizontal segment rigidity test macro includes horizontal segment test bracket, several adjusting screw rods, supporting baffle and pressure
Sensor；Several adjusting screw rods are separately fixed on horizontal segment test bracket, on each adjusting screw rod movably
It is connected with supporting baffle, the supporting baffle collectively forms tubular band test zone；Pressure sensor is connect with supporting baffle；
The turnaround section rigidity test macro includes turnaround section test bracket, connecting line and counterweight；Turnaround section test branch
Frame is connect or placed side by side or both for integral type bracket, connecting line one end in test with horizontal segment test bracket
It is connect with counterweight, the other end is around pulley blocks and tubulose band connection.
Further, further includes: computer control system, the computer control system are connect with pressure sensor, are used
Pressure data during collecting test is simultaneously handled pressure data.
Further, the horizontal segment test bracket is regular hexagon bracket, is respectively connected with adjusting screw rod on each side.
Further, the adjusting screw rod is equipped with slide bar, and adjusting screw rod one end is equipped with adjusting knob and is fixed on level
On section test bracket, the end of the other end and other adjusting screw rods is fixed together.
Further, supporting baffle is the contact plate of stainless steel.
Further, the connecting line passes through nailing submode and tubulose band connection.
Further, the horizontal segment test bracket and turnaround section test bracket bottom are respectively connected with for adjusting height
Adjust foot.
Further, the horizontal segment test bracket and turnaround section test bracket be in the same horizontal line.
The invention has the advantages that:
Carrying roller is replaced using supporting baffle, reduces frictional force caused by carrying roller, so that test data is more exactly and ideally,
Error is smaller when post-processing data.
Tubular band, by very big centripetal force, needs bigger in turning under the action of centripetal force, when tubular band is turned
Rigidity, if tubular band insufficient rigidity will appear the case where collapsing pipe, tubular band rigidity is excessive, in straightway pipe conveyer operate
When need bigger power, values of stiffness when there will be severe the case where pipe conveyer cannot operate, and testing turning more meets
The case where when pipe conveyer real-world operation, obtains more reasonable values of stiffness by test, to facilitate the good operation of pipe band.
