Abstract
The utility model discloses an automatic bidirectional reversible upper-aligning roller set, which comprises a support and a roller set mounted on the support. The automatic bidirectional reversible upper-aligning roller set is characterized in that the support comprises an upper cross beam and a lower cross beam, the roller set is mounted on the upper cross beam, and the center of the bottom surface of the upper cross beam is supported at the center of the lower cross beam through a rotating mechanism. The automatic bidirectional reversible upper-aligning roller set used during running process of a reversible conveyor reduces abrasion of rubber belts to the utmost extent, delays abrasion and breakage of conveying belts and prolongs service lives of the conveying belts. Further, the automatic bidirectional reversible upper-aligning roller set has an automatic deviation rectifying function, prevents the conveying belt deviating, and accordingly is more suitable for one-way or reversible belt conveyors with large belt width, long distance and high speed.
Description
Technical field
The utility model relates to the belt conveyer technical field, and particularly the employed bidirectional reversible of belt conveyer is gone up the aligning carrier roller group automatically.
Background technology
DTII and DTII (A) and original TD75 type taper aligning carrier roller are in the utilization and operation process, following situation appears easily: when rubber belt from deviating is serious, often cause a side taper aligning roller to tilt easily, connecting rod twist and cause and rotate dumb or transmission lags behind.The appearance of these situations has caused the taper aligning carrier roller not only can not rectify a deviation, and the bevelled roller scratches even tear adhesive tape easily with the middle roller dislocation.Not isometric because of central roll and corresponding flute profile Idler roller simultaneously, thus caused the side roller to be higher than the side roller of adjacent flute profile carrying roller, aggravated the wearing and tearing of adhesive tape, shortened the service life of adhesive tape.Be in operation and exist serious potential safety hazard that safety misadventure takes place easily.Bring heavy losses to user and enterprise.
The reason of belt deflection mainly contains following three aspects: crudy (being accuracy of manufacture), installation quality (being setting accuracy) and working service quality.
(1), crudy: the diameter dimension precision of cylinder; Carrying roller radial runout, rotation imbalance; The quality of load-transfer device; Hopper design unreasonable (asymmetric).
(2), installation quality: the geometric center lines of cylinder axis and conveyer complete machine and frame central line out of plumb; The conveying band joint quality is low; Stock guide does not wait the pressure of load-transfer device both sides.
(3), working service: reinforced misaligning; When tightening force is regulated, unequal in the both sides of load-transfer device.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of bidirectional reversible to go up the aligning carrier roller group automatically at the deficiencies in the prior art, thereby realizes the stability and safety operation of good deviation-correcting function and guarantee sealing-tape machine.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
Bidirectional reversible is gone up the aligning carrier roller group automatically, comprise support and rack-mount carrying roller group, it is characterized in that described support comprises upper and lower crossbeam, described carrying roller group is installed on the entablatrance, and the bottom center of described entablatrance is supported on the center of described cross sill by a rotating mechanism.
Described rotating mechanism comprises that one is fixed on the rotating shaft on the described entablatrance and is installed in the bearing seat on the cross sill and is embedded in tapered roller bearing in the described bearing seat, and described rotating shaft is connected with described tapered roller bearing.
Both sides in the bottom center of described entablatrance are provided with upper bracket, are provided with bracing frame in the both sides, center of described cross sill, and a turning cylinder is installed on each bracing frame, and a bearing that supports described upper bracket is installed on the described turning cylinder.
Described entablatrance is an integral structure, described carrying roller group comprises a central roll and two side rollers, wherein the two ends of central roll are installed in the midway location of entablatrance by two B-C posts, and two side rollers are installed in the both sides of entablatrance respectively by quarter line pillaring and described B-C post.
Owing to adopted design plan as above, the utility model compared with prior art has the following advantages:
A, because the base rotatable parts of original design use slide shaft to cause running insufficient sensitivity height, bearing owing to original design support-side roller lost efficacy easily in addition, make slide shaft be subjected to reverse loads such as torque and moment of flexure, the situation of having aggravated slide shaft flexural deformation even fracture takes place.The utility model changes the slide shaft of routine into rotating shaft, and employing simultaneously radially reaches the axial carrying characteristic, and good tapered roller bearing is rotated support, guarantees rotating shaft flexible no jam in operation process; Adopt simultaneously to add the lubricated and sealing means that fills grease in the bearing assembly cavity, prevented from that original design is the sort of slide shaft is directly assembled, issue the dead phenomenon of getting rusty, prolonged the service life of whole carrying roller group in bad working environments.
B, since the process of rubber belt from deviating in instantaneous generation, original design is that both sides taper aligning roller is supported on respectively on two bases, be assemblied in two side rollers on the base by the connecting rod mechanism interlock, especially under severe duty, cause connecting rod mechanism to lag behind easily, and central roll maintains static, and makes central roll homonymy roller misplace, thereby causes side roller junction roller circular cone end face to scratch adhesive tape.Simultaneously because connecting rod mechanism and frequent transmission of base and rotation make easy the becoming flexible of connecting rod mechanism cause transmission failure.Also aggravated simultaneously the generation of connecting rod mechanism endurance failure.Therefore the situation generation that rod deformation is crooked even break connecting rod is arranged.The utility model changes two base support in both sides and rotation into a rotating mechanism support rotation, simultaneously entablatrance is designed to an integral body, all be assemblied in central roll and side roller on the entablatrance, rotation by the centering rotating mechanism, feasible rotation is more flexible, rotational synchronization is better, and the correction sensitieness is higher.
C, entablatrance of the present utility model adopt unit design, entablatrance adopts both sides to adopt two upper brackets to support simultaneously, the rigidity and the intensity of entablatrance have been strengthened, improved the load-carrying capacity of entablatrance, can satisfy that entablatrance does not stay in the operational process, the not run-off the straight of side roller guarantees the steadily effectively operation of carrying roller group.
In reversible belt conveyer operational process, adopt the utility model bidirectional reversible to go up the aligning carrier roller group automatically, reduced the wearing and tearing of adhesive tape to greatest extent, avoided the load-transfer device rapid wear and torn, improved load-transfer device service life.Fully played the automatic deviation correction effect, prevented that load-transfer device operation sideslip effect is obvious.This technology more is applicable to the unidirectional or reversible belt conveyer of big bandwidth, long distance, high belt speed.
