Description
Technical field
The utility model belongs to belt conveyer technical field, relates to a kind of trough idler group, is specifically related to a kind of trough idler group preventing load-transfer device fold.
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.
The trough idler group that tradition uses is made up of three rollers, two limit rollers, a middle roller, middle roller horizontal arrangement, and two limit rollers become 35 degree or 45 degree of angles with horizontal surface, three roller composition flute profiles.The roller that tradition uses is all columniform, has a gap between adjacent two rollers.But load-transfer device operationally, due to the weight of material, often produce fold at this gap position, grown, and fold place cracks, and then splits gradually, causes load-transfer device to be scrapped by the time of operation, improve the maintenance maintenance expense of conveyer.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provides a kind of.
The utility model is achieved through the following technical solutions:
Prevent a trough idler group for load-transfer device fold, comprise limit roller, middle roller and carrier roller frame, the axial line level of middle roller, the axial line of limit roller becomes 35 degree or 45 degree of oblique angles with horizontal surface, three roller composition flute profiles; The two ends of middle roller are the central roll cambered surface ends of cancave cambered surface, and one end that limit roller is adjacent with middle roller is set as the limit roller cambered surface end of cancave cambered surface; In the perpendicular crossing three roller axial lines, the concyclic heart of circular arc of central roll cambered surface end and limit roller cambered surface end, etc. radius.
The arc radius R of above-described central roll cambered surface end and limit roller cambered surface end is within the scope of 100 to 300 millimeters, change according to load-transfer device width, rigidity and thickness, rigidity more greatly, thicker load-transfer device should use larger arc radius, otherwise should use less arc radius.
Load-transfer device operationally, is round and smooth arc in the both sides of gap position, and load-transfer device also can along with forming larger circular arc, instead of form obvious fold, this place is not easy to form crackle, effectively can extend the service life of load-transfer device, avoid maintenance maintenance expense to improve.
The beneficial effects of the utility model: in the service life effectively extending load-transfer device, avoid maintenance maintenance expense to improve.
Accompanying drawing explanation
Fig. 1 is the front elevation of the utility model embodiment;
Fig. 2 is the front elevation of middle roller 3;
Shown in figure: 1. load-transfer device; 2. limit roller; 3. middle roller; 4. carrier roller frame; 5. central roll cambered surface end; 6. limit roller cambered surface end; 7. roll shaft; R. the arc radius of central roll cambered surface end 5 and limit roller cambered surface end 6.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1 and Fig. 2.
Prevent a trough idler group for load-transfer device fold, comprise limit roller 2, middle roller 3 and carrier roller frame 4, the axial line level of middle roller 3, the axial line of limit roller 2 becomes 35 degree or 45 degree of oblique angles with horizontal surface, three roller composition flute profiles; The two ends of middle roller 3 are central roll cambered surface ends 5 of cancave cambered surface, and one end that limit roller 2 is adjacent with middle roller 3 is set as the limit roller cambered surface end 6 of cancave cambered surface; In the perpendicular crossing three roller axial lines, the concyclic heart of circular arc of central roll cambered surface end 5 and limit roller cambered surface end 6, waits radius.
The arc radius R of above-described central roll cambered surface end 5 and limit roller cambered surface end 6 is within the scope of 100 to 300 millimeters, change according to load-transfer device width, rigidity and thickness, rigidity more greatly, thicker load-transfer device should use larger arc radius, otherwise should use less arc radius.
Load-transfer device 1 operationally, is round and smooth arc in the both sides of gap position, and load-transfer device 1 also can along with forming larger circular arc, instead of form obvious fold, this place is not easy to form crackle, effectively can extend the service life of load-transfer device 1, avoid maintenance maintenance expense to improve.
The beneficial effect of the present embodiment: in the service life effectively extending load-transfer device, avoid maintenance maintenance expense to improve.
