Abstract
The utility model discloses an articulated three-carrying-roller set. The articulated three-carrying-roller set comprises two hooks, two side carrying rollers, a cylindrical carrying roller and multiple hinges. Each side carrying roller comprises a cylindrical roller and a taper sleeve sleeving outside each cylindrical roller. The cylindrical rollers are connected between the hooks and the cylindrical carrying roller via the hinges. A large head end of each taper sleeve is opposite to each hook and a small head end of each taper sleeve is opposite to the cylindrical carrying roller. The articulated three-carrying-roller set has following beneficial effects: expanding angles are formed between generatrices above the side carrying rollers and a central axis due to the fact that taper sleeves sleeve outside the side carrying rollers; when a belt operates on the carrying-roller set, two sides of the belt are subjected to resistance force applied by the side carrying rollers towards an upward and inside portion so that centers of two sides of the belt are lifted, with the result that resistance force applied to the belt during deviation increases to effectively lessen the possibility of deviation; and the articulated three-carrying-roller set is simple in structure, convenient in refitting and considerable in anti-deviating force.
Description
Technical field
The utility model relates to roller for belt conveyer device, relates in particular to a kind of radial type three carrying roller groups.
Background technology
Carrying roller is the vitals of belt conveyer, and its Main Function is back(-)up belt, reduces belt running resistance, and makes the squareness of belt be no more than certain limit to ensure that belt moves reposefully.Carrying roller running must flexibility and reliability.Reduce load-transfer device with the friction force of carrying roller, the life-span that accounts for more than 25% load-transfer device of conveyer total cost is played to key role.Carrying roller divides of a great variety by its purposes, wherein, trough idler is mounted in the main device in the heavy duty section of conveyer, as shown in Figure 3, it is generally made up of two side carrying roller a and a flat carrier roller b, and the angle of the v-groove is generally 30 degree, for detachable belt conveyer, three carrying rollers of trough idler are together mutually hinged, therefore claim Hinge linked supporting roller.Because three carrying rollers in existing Hinge linked supporting roller are all the cylindrical structurals adopting, its correction dynamics is less, in the operational process of belt, deviation phenomenon can occur unavoidably.
Utility model content
The purpose of this utility model is to provide a kind of effective radial type three carrying roller groups simple in structure, anti-deviation.
This radial type three carrying roller groups that the utility model provides, comprise two hooks, two side carrying rollers, a cylinder carrying roller and some hinges, each described side carrying roller comprises cylindrical roll and is sleeved on the tapered sleeve outside this cylindrical roll, described cylindrical roll is hinged through the hinge between described hook and cylinder carrying roller, the stub end of described tapered sleeve is relative with hook, and the little head end of this tapered sleeve is relative with cylinder carrying roller.
The cone angle of described tapered sleeve is 6 °.
The end face diameter of the little head end of described tapered sleeve and the equal diameters of described cylinder carrying roller.
The end face vertex of the little head end of described tapered sleeve is not less than the level height of described cylinder carrying roller Up Highway UHW.
Described cylindrical roll and tapered sleeve can be made into all-in-one-piece round table-like carrying roller.
The utility model puts a tapered sleeve outward by the side carrying roller at existing hinge type carrying roller, make to become between the bus of top of side carrying roller and central axis certain expansion angle, in the time that belt moves in this carrying roller group, its both sides can be subject to surveying the resistance of carrying roller points upwards inner side, the center of belt both sides is increased, resistance suffered while causing belt deviation strengthens, and has effectively prevented the possibility of its sideslip.The utility model is simple in structure, and repacking is convenient, anti-deviation great efforts.
Brief description of the drawings
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Fig. 3 is the structural representation of prior art.
Detailed description of the invention
Can find out from Fig. 1 and Fig. 2, this radial type three carrying roller groups of the utility model, comprise two hooks 1, two side carrying rollers 2, cylinder carrying roller 3 and some hinges 4, wherein each side carrying roller 2 all comprises a cylindrical roll 21 and a tapered sleeve 22, between hook 1 and one end of cylindrical roll 21, be all connected by hinge 4 between the other end of cylindrical roll 21 and cylinder carrying roller 3, make it entirety and be a grooved, tapered sleeve 22 is sleeved on outside cylindrical roll 21, and the stub end of this tapered sleeve 22 is relative with hook 1, and its little head end is relative with cylinder carrying roller 3.
It can also be seen that from Fig. 1, the cone angle of the utility model tapered sleeve 22 is 6 °, the end face diameter of tapered sleeve 22 little head ends and the equal diameters of cylinder carrying roller 3, and the end face vertex of tapered sleeve 22 little head ends is not less than the level height of cylinder carrying roller 3 Up Highway UHWs.
It can also be seen that from Fig. 2, cylindrical roll 21 of the present utility model and tapered sleeve 22 can be made into all-in-one-piece round table-like carrying roller, the cone angle of this round table-like carrying roller is 6 °, the equal diameters of the end face diameter of its little head end and cylinder carrying roller 3, the end face vertex of its little head end is not less than the level height of cylinder carrying roller 3 Up Highway UHWs.
