Description
Technical field
The utility model relates to a kind of deviation correcting device of belt conveyer, especially for the automatic roller rack corrector of flute profile belt conveyer.
Background technology
The belt deviation phenomenon is band conveyor common faults in operational process.If belt deviation seriously, gently then causes belt to damage, heavy then cause belt tearing, influence the service life of belt; Belt also can cause spreading, shutdown etc. because of the sideslip face in operational process in addition; Both influence production, and can cause serious economy loss again.Chinese patent CN2477584 discloses the adjustable full-automatic rectification device of a kind of roller rack, and it is made up of base, edger roll, carrying roller and roller rack; Three carrying rollers by three independently roller rack supported, the inner of both sides roller rack fixes by rotating shaft and the carrier base that is loaded on the base, and roller rack can rotate around the axis; The outer end of both sides roller rack places the top to be provided with on the bracing frame of rolling bearing.By the drive of connecting rod mechanism, moving of the rotation of carrier base and carrying roller realizes the correction effect, this type of deviation correcting device complex structure, and base has the rotating mechanism of connecting rod mechanism, carrier base, the cost height.
Summary of the invention
It is a kind of simple in structure that the utility model provides, and cost is low, the automatic roller rack corrector that rectifying effect is good.
The utility model is achieved by the following technical solution: automatic roller rack corrector, comprise base, edger roll, carrying roller and roller rack, described three carrying rollers by three independently roller rack supported; The inner of described both sides roller rack is connected with base by revolute pair, described deviation correcting device also comprises connecting lever, one end of described connecting lever is connected with edger roll, and the other end is connected with the roller rack outer end, and the flex point of connecting lever is connected with connecting lever axle base by the connecting lever axle.
Described connecting lever axle base is provided with limiting device.
Described deviation correcting device also comprises the edger roll rail bracket, and described edger roll rail bracket is installed on the roller rack of both sides, and described edger roll is installed in the edger roll rail bracket, and described edger roll can move along the edger roll track.
Described edger roll rail bracket is installed in the outside, roller rack top, both sides, constitutes moving sets with edger roll.
Described connecting lever is connected with edger roll by connecting rod.
The other end of described connecting lever is connected by pin with bottom, roller rack outer end.
The utility model is simple and reasonable, cost is low, moves by edger roll is stressed, acts on connecting lever, and connecting lever is stressed, with the connecting lever point is fulcrum, and connecting lever rotates around the connecting lever axle, adjusts roller rack, roller rack is rotated around the axis, and edger roll reacts on belt, reaches the purpose of correction.
Principle of work
When sideslip appears in belt, for example skew left, then the edger roll on the left side is stressed is moved to the left, edger roll pushes connecting lever left, and connecting lever is that fulcrum rotates to an angle in the counterclockwise direction with the connecting lever axle, pushes up on the other end of connecting lever, make roller rack make clickwise with the movable point of attachment rotating shaft of roller rack and base, edger roll is subjected to the squeese pressure of belt, the lever force of connecting lever, the gravity of roller rack to reach new balance, and edger roll reacts on belt, causes belt to move right.After belt was just walked, the three recovered original balance, the roller rack self-return.Otherwise belt causes belt to be offset left when right avertence, plays the effect of correction.
