Description
Technical field:
The utility model relates to the conveyer field, and particularly a kind of spring loaded bend horizontal angle due to lifting at the inside is regulated the flute profile adjusting centre roll device automatically.
Background technology:
The transportation of bulk cargo at present mainly be take belt conveyer as main, development along with transit industry, in order to simplify transit link, reduce investment, Belt Conveyor with Horizontal Curves is widely used, Belt Conveyor with Horizontal Curves and generally belt conveyer difference mainly at bending section, the measure that realizes plane turning has forced guiding to turn and natural break-in turning, forced guiding turning measure need to increase special steering hardware, and the corresponding investment that increases equipment, generally do not adopt.It is to make load-transfer device by the operation of Laws of Mechanics natural torsion that the nature break-in is turned, and realizes that the gordian technique that the nature break-in is turned is to make the load-transfer device bending section produce balance centripetal force, and major measure is to make the bending section inner curve raise an angle.Way of realization has constant tilt carrier roller frame structure at present, and inner curve arranges idler structure etc.But through relatively finding that there is following defect: constant tilt carrier roller frame structure, because correction angle due to the force of gravity is fixed, spreading and belt deflection easily occur, and makes the structure complicated at turning; Inner curve arranges this structure of carrying roller has increased a side carrying roller, and the roller rack structure is increased, and cost increases, and the wearing and tearing of aggravation adhesive tape.
Summary of the invention:
In view of this, be necessary to provide a kind of spring loaded bend horizontal angle due to lifting at the inside automatically to regulate the flute profile adjusting centre roll device.
A kind of spring loaded bend horizontal angle due to lifting at the inside is regulated the flute profile adjusting centre roll device automatically, comprises carrying roller, carrier roller frame, left edger roll, right edger roll, and it is characterized in that: carrier roller frame comprises entablatrance, cross sill, rotary components, Connection Block, spring assembly, hinged support; Carrying roller is arranged on entablatrance, left edger roll, right edger roll be the corresponding two ends, left and right that are arranged on entablatrance respectively, and rotary components is fixedly connected with entablatrance, cross sill, and Connection Block is connected with an end of cross sill, spring assembly is arranged on hinged support, and is connected with the other end of cross sill.
Preferably, carrier roller frame also comprises positioning plate, and positioning plate is fixedly mounted on rotary components by screw.
Preferably, Connection Block is fixedly connected with by bearing pin with cross sill.
Preferably, spring assembly is fixedly connected with by bearing pin with hinged support.
Preferably, rotary components and entablatrance are fixedly connected by welding.
Preferably, spring assembly is comprised of two cylindrical helical springs.
Load-transfer device is made a concerted effort along normal to a curve direction sensing inboard bending section tension force, and this will make the inside sideslip of load-transfer device with joint efforts.Owing at bending section, bend horizontal angle due to lifting at the inside being set, the outside thrust produced by material and load-transfer device gravity, carrying roller arranges the load-transfer device of inclination angle generation and the centrifugal friction power between carrying roller, these three power of centrifugal inertia force during turning are all pointed to the outside, make load-transfer device produce the outside thrust of closing, when close thrust and tension force make a concerted effort to reach balance the time, realized that the automatic centering of conveyer is regulated, thereby avoided spreading and belt deflection.Play decisive role so close the size of thrust, the size of closing thrust is relevant with the inclination angle that material and load-transfer device gravity, carrying roller arrange, so should regulate bend horizontal angle due to lifting at the inside according to the material of actual loaded at any time, guarantee load-transfer device steady trun.Be downloaded to fully loaded change procedure because the conveyer convey materials is free.The principle that should follow makes correction angle due to the force of gravity larger while being zero load, and at full load makes correction angle due to the force of gravity less, by producing, closes accordingly the centripetal force that thrust is carried out the balance bending section.According to plane system of couples equilibrium principle, according to unloaded and fully loaded two extreme values, calculate the minimum and maximum pressure that spring is produced, computing formula is: F
1L
1=FL, in formula
For material and parts total force, unit is N,
L 1 For material and parts center of gravity, to the hinge-point horizontal throw, unit is mm, and F is the pressure that material and parts integral body produce spring, and unit is N, L be the spring axis to the hinge-point horizontal throw, unit is mm; Again according to the bend horizontal angle due to lifting at the inside range of control between 2 ° ~ 6 °, calculate amount of spring compression and forced stroke, then, by Hook's law, calculate elasticity modulus, and then select suitable cylindroid helical-coil compression spring.Just can play the purpose of automatically regulating in real time bend horizontal angle due to lifting at the inside.
When the belt feeder no-load run, only have adhesive tape and the weight of carrying roller group own, spring pressure minimum now, bend horizontal angle due to lifting at the inside is in 6 °.Along with material increases gradually, amount of spring compression increases, and carrier roller frame integral body will be around the bearing pin clickwise, and when the belt feeder at full load, bend horizontal angle due to lifting at the inside narrows down to 2 ° gradually, reaches the purpose of automatically regulating in real time bend horizontal angle due to lifting at the inside.When belt deflection, adjusting centre roll device can rotate around S. A., encounters positioning plate and stops, and has now rotated an angle (1.5 °), load-transfer device is passed on the line of centers of conveyer, makes the operation of conveyer steady trun.
So, adopt the utility model, can avoid spreading and belt deflection, guarantee bending section load-transfer device stress balance, make the operation of conveyer steady trun.And lightweight, convenient transportation, assembly and disassembly are simple.Reduce labor strength, improved work efficiency.
