Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Belt run-out is the most common fault when the belt conveyor is running. The deviation adjusting device has various kinds, such as adjusting the bearing roller set, installing the aligning roller set, adjusting the positions of the driving roller and the bend roller. The carrier roller forward tilting deviation adjusting device has the advantages that the structure is complex, the production and the processing are difficult, the deviation adjusting effect is limited, the deviation adjusting effect is good, but some negative effects can be produced, for example, the structure is complex by adopting the aligning carrier roller, the cost is high, when the carrier roller forward tilting deviation adjusting device is adopted, certain transverse force is produced on the belt due to different rotating speeds inside and outside the carrier roller in the whole process, the belt is driven to automatically move inwards, the deviation preventing effect is achieved, and the effect is poor due to the existence of the transverse force. The phenomenon of belt deviation is not solved fundamentally, which is one of the root causes of poor deviation adjusting effect.
The deviation is studied from the factors causing the deviation of the belt, namely from the aspects of the head part of the belt, the position of the driving roller and the direction-changing roller, the additional deviation adjusting device and the like, and finally, the deviation adjusting device is additionally arranged in front of or behind the guide roller to adjust the deviation, and the difficulty is that the diameter of the deviation adjusting roller is determined, the diameter is too large to be fixed, the diameter is too small to play a role in deviation adjustment, the size is required to be measured on site, and the proper deviation adjusting roller is processed.
The deflection regulating device provided by the utility model consists of a group of deflection regulating carrier rollers and a group of fixed brackets, wherein the deflection regulating carrier rollers are required to be designed and processed according to requirements, and the method of modifying the lower carrier roller (flat carrier roller) of a belt can be also adopted. The existing deviation adjusting carrier roller works in a passive adjustment mode, the deviation adjusting carrier roller is not fixed, and when the belt deviates and the edge of the belt contacts with the side roller, the belt returns to the normal position. Because of the hysteresis of the motion, the effect of correcting the deviation is not ideal, and meanwhile, the edge of the belt rubs with the side roller for a long time, so that the damage of the edge of the belt is accelerated.
As shown in fig. 1, the present utility model provides a belt conveyor deviation adjusting device, which includes two deviation adjusting mechanisms oppositely disposed at two sides of a machine head of a belt conveyor, the deviation adjusting mechanisms include:
the vertical fixing frame 1 is fixed on the large frame of the belt conveyor and positioned at the side part of the guide roller of the belt conveyor;
The carrier roller mounting seats 2 are arranged on one side of the vertical fixing frame 1, which faces the guide roller, the number of the carrier roller mounting seats 2 is consistent with the number of belt layers on the belt conveyor, and a plurality of carrier roller mounting seats 2 are arranged in a straight line along the length direction of the vertical fixing frame 1;
And the deviation adjusting carrier rollers 3 are in one-to-one correspondence with the carrier roller mounting seats 2, and the deviation adjusting carrier rollers 3 are vertically arranged.
The utility model is arranged at the guide roller of the belt, because the upper layer and the lower layer of the belt are 5 layers, if one layer is singly adjusted, the deviation adjusting effect can not be achieved, so the utility model is designed into 5 deviation adjusting carrier rollers, and the deviation adjusting carrier rollers are connected between the guide roller and the large frame by a fixing frame and a fixing lug. When one layer is deviated, the edge of the belt can touch the corresponding deviation adjusting carrier roller to enable the belt to return to the normal position, and when the belt is deviated to the other side, the deviation adjusting carrier roller at the other side is used for adjusting the deviation adjusting carrier roller. The belt deviation adjusting device solves the problems of difficulty in deviation adjustment during no-load operation of the belt and serious deviation during no-load operation.
The utility model mainly comprises a group of deflection-adjusting carrier rollers and a group of fixed brackets. The appearance simple structure, the installation is changed portably, the advantage that the maintenance is little.
In order to be suitable for belts with different pitches, in one embodiment of the belt conveyor deviation adjusting device provided by the utility model,
The vertical fixing frame is provided with a vertical sliding groove, and the bottom surface of the carrier roller mounting seat is provided with a sliding block matched with the vertical sliding groove;
the vertical fixing frame is also provided with fixing blind holes at two sides of the vertical sliding chute;
The carrier roller mounting seat is provided with a mounting hole, and a fixing piece penetrates through the mounting hole and the fixing blind hole to fix the carrier roller mounting seat on the vertical fixing frame.
In one embodiment of the belt conveyor deviation adjusting device provided by the utility model, the carrier roller mounting seat comprises two sliding supports which are arranged oppositely, so that the length of the carrier roller can be changed according to different requirements.
In one embodiment of the belt conveyor deviation adjustment device provided by the utility model,
A vertical flat carrier roller is further arranged on one side of the vertical fixing frame, which is positioned on the offset carrier roller, and the length of the vertical flat carrier roller is the sum of the lengths of the offset carrier rollers;
the diameter of the vertical flat carrier roller is the same as that of the deviation adjusting carrier roller, so that an auxiliary effect is achieved, and the belt is prevented from being clamped in the fixed lugs.
In one embodiment of the belt conveyor deviation adjusting device provided by the utility model, two connecting lugs are arranged on the side edges of the vertical fixing frame, and threaded holes are formed in the connecting lugs so as to be fixed with the large frame.
Compared with the methods of adjusting the bearing roller group, installing the aligning roller, adjusting the positions of the driving roller and the bend roller, and the like, the deviation adjusting device is mainly used for adjusting the deviation of the belt at the idle section of the guide roller, and the effect is better. If the conveyor belt is deviated, the belt is regulated back to the middle running route under the action of friction force. Simple structure has avoided the damage of belt. Only a group of deflection-adjusting carrier rollers are needed to be processed, and the use is very convenient.
The utility model mainly solves the problems of poor deviation adjusting effect, unreasonable design of the deviation adjusting device and serious deviation of the belt existing in the existing deviation adjusting device. The belt deviation adjusting device has extremely high deviation adjusting performance, protects the conveying belt and has small maintenance amount. The cost is saved, the installation is easy, and the service life is long.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
