Description
Technical field
The utility model belongs to belt conveyer technical field, is specifically related to a kind of device increasing friction force between load-transfer device and cylinder.
Background technology
Traditional belt conveyer comprises load-transfer device, head roll, bend pulley, head drum, aircraft tail cylinder, actuating device, tightening device, the component such as carrying roller and rack construction, aircraft tail cylinder is arranged in charging end, head drum is arranged in throw-off end, actuating device and head roll are connected, head roll is generally arranged in throw-off end, working edge is made to be pilled-in selvedge, head drum also can serve as head roll simultaneously, head roll can be one, also can arrange multiple, load-transfer device is around between each cylinder, and have the tensile force of suitable size, need the location arrangements bend pulley changing direction, carrying roller is arranged in linear portion or changes less position, direction, for supporting belt deadweight and weight of material.Actuating device drives head roll running, head roll relies on the running of friction force driving conveying belt, other cylinder and carrying roller follow rotation passively, material is loaded by charging end, unload from head drum, load-transfer device continuously operates, and just material can continuously be transported to throw-off end by charging end and unload.
Belt conveyer uses widely, both bulk material can be transported, also work piece can be transported, both can operate continuously, also can match with the technological process in production procedure, form rhythmical Detroit automation lane of traffic, powdery can be transported, granule, little lump material, medium size can also be transported, bulk materials, even can more than 600 millimeters, environment for use is generally-20 DEG C to+40 DEG C, also the high temperature resistant type conveyer that can adapt to 500 DEG C had, it runs at a high speed, steadily, noise is low, and can uphill/downhill transmission, so be widely used in coal, ore, sand, cement, chemical fertilizer, the all trades and professions such as grain.
Make between head roll and load-transfer device, there is larger friction force, conveying just must be made with the tensile force of suitable size, have between tensile force head roll and load-transfer device and could produce positive pressure, friction force could be produced between contact surface, positive pressure and friction force proportional, proportionality coefficient is the coefficient of static friction between two surfaces.Also need the area of contact having suitable size between load-transfer device and cylinder, in order to enlarge active surface, often arrange bend pulley in position, make load-transfer device on head roll, have the cornerite that size is suitable.
Improve the transport capacity of conveyer, will increasing friction force, tensile force will be increased, and increase tensile force and will pay a price, often need the rigidity increasing rack construction part, cylinder, carrying roller, to keep the due stable shape of conveyer, in running condition can not produce obviously distortion or parts disrumpent feelings, will increase the quantity of the material that these parts use or improve the quality of material, the cost of whole conveyer will improve.
Application number is the Chinese utility model patent of 201120350346.6, and name is called " increasing the adhesive tape of travelling apron and the device of roll friction power ", describes a kind of increase tensile force that do not need and just can assist the device increasing friction force.This utility model belongs to belt conveyer equipment technical field, particularly relates to a kind of device increasing friction force between the load-transfer device of belt conveyer and cylinder.By ground way, the traversing carriage of ground way sliding block joint therewith, the therewith rocker bearing that is fixedly connected with of traversing carriage, the one group of roller component be located on this rocker bearing formed, and rocker bearing is located at the outside of conveyer head roll.Roller component is made up of the roller mount be connected with rocker bearing and roller mount is rotationally connected therewith roller, and roller outside face rolls with the adhesive tape on travelling apron and is connected.This utility model is closely abutted against by the load-transfer device on one group of roller component and head roll outside face, increases the force of rolling friction between adhesive tape and cylinder, avoids adhesive tape slipping phenomenon, thus reaches the object increasing propulsive effort, increase the transport capacity of conveyer.
This utility model need not increase tensile force, just can increase the positive pressure between load-transfer device and cylinder, thus increasing friction force, compare traditional belt conveyer and really make great progress, but also add very important shortcoming simultaneously.
Contact between roller and load-transfer device is linear contact lay, local repeatedly extrudes and loosens load-transfer device, load-transfer device local is made to be subject to excessive squeese pressure, shearing force, flexure stress, conveyor belt surface easily produces fine crack, and in running condition load-transfer device is extruded endlessly and loosens, and fine crack develops expansion gradually and just becomes large crackle, load-transfer device is finally caused to destroy, in the service life of obvious shortening load-transfer device, need more to renew load-transfer device, add the maintenance cost of conveyer.
Elastomeric material is meeting lot of energy in the process be extruded and loosen, and the some mechanical kinetic energy that head roll passes to load-transfer device does not utilize on transmission material, but is transformed to heat energy dissipation in the environment, causes energy dissipation.
The roller component of this utility model, its size is difficult to do each pair of rollers load-transfer device applies equal pressure, even if that does is suitable, load-transfer device is in use because abrasion can be thinning gradually, surround the radius after on head roll can diminish gradually, and the size constancy of rocker bearing, the diminish roller at rear arc two ends of radius does not just reach load-transfer device, lose due effect, it is thinning that load-transfer device continues wearing and tearing, then adjacent roller is also ineffective, finally only has the minority one or two of arc midpoint in work, does not reach the result of use of expection.Load-transfer device is consumable store, when more renewing spare part, needing in a lot of situation to change its structure according to the service condition of old load-transfer device, such as increasing the thickness of driving surface sizing material to strengthen resistance to abrasion, canvas core is replaced with Steel cord to strengthen its resistance to tension etc., changing of design inevitably causes its thickness to change, and the size of roller component can not the change of auto-compensation size, and comformability is poor, need adjustment, thinning gradually in use procedure, need frequently to adjust, use and inconvenience.
In a word, a kind of load-transfer device that can keep urgently is released compared with long life, more energy-conservation, that comformability is stronger technical scheme.
