Abstract
A passive hydraulic control linkage rectification machine which can rectify and prevent the run deviation of a conveyor belt consists of a hydraulic control detecting and driving system and a linkage rectification mechanism. The hydraulic control detecting and driving system consists of a detecting and driving wheel, an oil pump, a cylinder, a midpoint controlling station, a temperature controller and an oil pipe. The linkage rectification mechanism consists of discrete rollers, roller racks, a universal joint, an arm rod, a connecting rod, a pin and a frame. The hydraulic control detecting and driving system is used to detect the run deviation of the belt and simultaneously supplies power for driving the roller racks to deflect. When the belt runs deviated, the belt drives the detecting and driving wheel to rotate. The detecting and driving wheel drives the oil pump to strike the oil pressure to the midpoint controlling station. A logistic valve group of the midpoint controlling station controls the piston rod of the cylinder (4) to push or pull. The piston rod drives the linkage rectification mechanism to lead the roller (11) on the mechanism to deflect synchronously in the same direction. An angle is formed between the linear moving direction of the roller after the deflection and the moving direction of the belt, and the transverse friction of the belt generating during the above process drives the belt to run in the middle. The passive hydraulic control linkage rectification machine requires no power and hydraulic function and has the advantages of synchronous linkage, self-defecting, self-driving and self-system.
Description
Technical field
The present invention relates on the belt conveyer a kind of be used to correct prevent the be in operation deviation correcting device of sideslip of belt.
Background technology
At present, being applied to deviation correcting device in all kinds of belt conveyers mainly is various aligning carrier rollers and forward-tilt idler and the electricity deviation correcting device that surges.
No matter be which kind of aligning carrier roller, the principle of the correction belt deviation of its imagination all is: when the misalignment of belt is carried the operation of frame longitudinal centerline, aligning carrier roller mechanism should detect belt deviation, and the aligning carrier roller frame is deflected, aligning carrier roller line sense of motion and belt movement direction form angle after the deflection, form belt side-friction between aligning carrier roller and the belt this moment, utilizes this side-friction, orders about belt to the displacement of belt frame center.But various pure mechanical aligning carrier rollers all exist belt deviation is detected ineffective slow in reacting, correction power deficiency, the size that can not regulate the deflection angle of aligning carrier roller according to the size of belt deviation power voluntarily is producing adaptive correction power, and accurate location.When promptly less sideslip took place belt at that time, the aligning carrier roller frame detected less than not deflection, even deflection has taken place the aligning carrier roller frame, the angle that can not determine deflection voluntarily is sprocket bit in addition also, and centering capacity also often is not enough to correct belt deviation.
Forward-tilt idler is that the artificial carrying roller with both sides on the belt frame fixedly leans forward, therefore no matter still sideslip not of belt deviation, and all there is axial force in the carrying roller of belt both sides.Positive pressure on belt one side forward-tilt idler is greater than the positive pressure on the opposite side forward-tilt idler, and when producing friction force greater than the horizontal sideslip power of belt between belt and forward-tilt idler, just can make belt to carrying the frame centre bit to move.Forward-tilt idler leans forward owing to it fixedly installs carrying roller, thereby when belt moves, no matter whether there is axial force in forward-tilt idler to belt deviation all the time, increased the resistance of motion of belt the service life that this can reduce Idler bearing and roller supporting tube skin, strengthened the operation power consumption, and can increase watt loss along with the increasing of load, particularly increased the resistance of band conveyor full load starting greatly, starting current strengthens, and is difficult to starting.
The electricity deviation correcting device that surges is a current consumer element testing belt deviation, drives the deflection of aligning frame with electronic or Electrohydraulic push rod.Because electric hydraulically operated deviation correcting device need use power supply, again because of belt deviation rectifying is often needed its frequent movement, and poor working environment, and existing the fault rate height, correction power is also often not enough.
