Description
Technical field
The utility model belongs to belt conveyer technical field, relates to a kind of transition phase equalization of pressure gasifying device, is specifically related to a kind of belt conveyer transition phase pressure roller.
Background technology
Traditional belt conveyer comprises load-transfer device, head drum, aircraft tail cylinder, head roll, actuating device, trough idler group, the component such as snub pulley 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, simultaneously head roll only has to drive the cylinder of function or head roll to serve as head drum, load-transfer device is around between each cylinder, trough idler group and snub pulley are arranged between each cylinder, load-transfer device linear portion or the position that change direction is less up and down, for supporting belt deadweight and weight of material, load-transfer device working edge and inoperative limit consistency from top to bottom, and have the tensile force of suitable size.Actuating device drives head roll running, head roll is operated by friction force driving conveying belt, other cylinder and carrying roller follow rotation passively, material is loaded by tail, unload from head drum, actuating device continuously operates, and material just can continuously be transported to throw-off end by charging end and unload by load-transfer device, then is returned by inoperative limit.
Load-transfer device is flute profile in normal material containing section, and being arranged to flute profile can increase material containing amount.Load-transfer device wants generate plane when walking around aircraft tail cylinder, then through one section of transition phase, gradually change to normal flute profile, and the groove angle being positioned at the trough idler group of transition phase is less than the groove angle of normal trough idler group, and this groove angle is also transition gradually from small to large.Draw a plane from load-transfer device and the tangent position of aircraft tail cylinder towards the direction that load-transfer device runs, this plane is the theoretical planes of load-transfer device, is the benchmark calculating the every physical parameter of load-transfer device.After load-transfer device is transited into flute profile, the edge of load-transfer device is in more than theoretical planes, the middle part of load-transfer device is positioned at below theoretical planes, the distance of each position diagonal of load-transfer device is not etc., belt edges and middle part are added stretching, therefore can produce additional potential stress, and the position tensile stress be in theoretical planes is less than zero, namely what is called makes load-transfer device Cross deformation, and pars intermedia swells.If transition phase distance is less, in hightension district, belt edges will produce excessive additional stress, makes load-transfer device occur fatigue phenomenon prematurely, even can cause the accidents such as belt edge drawing crack when serious.Transition phase is designed longer this phenomenon that can slow down occurs, but those needs take ground more, consume manufactured materials more, cause manufacturing cost to improve.Up to the present better solution is not also had.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the belt conveyer transition phase pressure roller adapting to reality need, provide a kind of and avoid producing excessive subsidiary load, avoid load-transfer device premature fatigue, extend load-transfer device service life, reduce floor area, reduce material consumption.
The utility model is achieved through the following technical solutions:
A kind of belt conveyer transition phase pressure roller, comprise press roll component, chute and hydraulic actuating cylinder, press roll component comprises pressure roller, pressure roller shaft and slide, pressure roller and pressure roller shaft form revolute pair, pressure roller shaft end and slide are fixedly connected, chute is vertical direction, slide and chute form moving sets, cylinder bar or the cylinder barrel of slide and hydraulic actuating cylinder are connected, the cylinder barrel of hydraulic actuating cylinder or cylinder bar and frame are fixedly connected, pressure roller has two sections of arc surfaces, arc surface pushes down position load-transfer device being in theoretical zone face, i.e. the minus region of tension force.Hydraulic actuating cylinder applies power to slide, then press roll component is along chute upper and lower translation, the minus region of the tension force of arc surface to load-transfer device just produces pressure, the tension force in this region is just no longer less than zero, but tension force becomes more equalization along cross-sectional plane, load-transfer device is in a kind of new balance and stabilized conditions, belt edges is effectively avoided to produce excessive additional stress, load-transfer device is effectively avoided to occur fatigue phenomenon prematurely, effectively avoid the accidents such as belt edges drawing crack, extend the service life of load-transfer device, the length of transition phase suitably can also be shortened, reduce floor area, reduce material consumption, reduce the manufacturing cost of whole belt conveyer.
The beneficial effects of the utility model: effectively avoid belt edges to produce excessive additional stress, load-transfer device is effectively avoided to occur fatigue phenomenon prematurely, effectively avoid the accidents such as belt edges drawing crack, extend the service life of load-transfer device, reduce floor area, reduce material consumption, reduce the manufacturing cost of whole belt conveyer.
