Abstract
The invention discloses a bidirectionally-reversible automatic descending aligning idler set. The aligning idler set comprises a bracket and an idler set arranged on the bracket and is characterized in that: the bracket comprises upper and lower beams; the idler set is arranged on the upper beam; and the center of the bottom surface of the upper beam is supported at the central position of the lower beam through a rotating mechanism. Due to the adoption of the bidirectionally-reversible automatic descending aligning idler set of the invention in the running process of a reversible belt conveyor, the abrasion of a rubber belt is reduced to the maximum extent, too fast abrasion and tearing of a conveyer belt are avoided and the service life of the conveyer belt is prolonged. The automatic error correction effect is achieved fully and the running deviation prevention effect on the conveyer belt is remarkable. The technology is more suitable for a one-way or reversible belt conveyer with a large belt width, long distance and high belt speed.
Description
Technical field
The present invention relates to the belt conveyer technical field, particularly the employed bidirectional reversible of belt conveyer descends 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 bevelled both sides side roller dislocation scratches even tear adhesive tape easily, can not realize good deviation-correcting function, has aggravated the wearing and tearing of adhesive tape simultaneously, has shortened the service life of adhesive tape.
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.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of bidirectional reversible to descend 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 matters to be solved by this invention can be achieved through the following technical solutions:
Bidirectional reversible descends 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, and described carrying roller group comprises two side rollers, and wherein two side rollers are installed in the both sides of entablatrance respectively by quarter line pillaring and B-C post.
Owing to adopted design plan as above, the present invention 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 present invention 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, simultaneously because connecting rod mechanism and frequent transmission of base and rotation make easy the becoming flexible of connecting rod mechanism cause transmission failure.Therefore the situation generation that rod deformation is crooked even break connecting rod is arranged.The loosening easily ring that decreases of side supports, both sides side roller forms wedge angle, and the mill of aggravation adhesive tape is contributed and is decreased.Simultaneously can not realize the function of rectifying a deviation.The present invention changes two base support in both sides and rotation into a rotating mechanism support rotation, simultaneously entablatrance is designed to an integral body, all is assemblied in both sides side roller on the entablatrance, rotation by the centering rotating mechanism, feasible rotation is more flexible, and rotational synchronization is better, and the correction sensitieness is higher.
C, entablatrance of the present invention 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 bidirectional reversible of the present invention to descend 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.
