The utility model provides a pair of bucket wheel dress reclaimer exit conveyor gyration hydraulic control mechanism, it is small, thrust is big. The volume of the hydraulic cylinder is determined by the diameter and the length of the hydraulic cylinder, so that the hydraulic cylinder is suitable for the working requirement of the bucket-wheel loading and unloading machine for discharging and rotating the material belt. Meanwhile, the pushing acting force generated by the hydraulic oil cylinder is determined by the diameter of the hydraulic cylinder and the pressure of a hydraulic system. As long as the thrust of the oil cylinder is greater than the thrust required by the rotation of the conveyor belt, the hydraulic cylinder has strong capability of bearing reaction moment.
Description
Technical Field
The utility model relates to a material field of carrying, in particular to bucket wheel dress reclaimer exit conveyor gyration hydraulic control mechanism.
Background
The discharge conveyor belt of the bucket-wheel loading reclaimer is one of the main components of the discharge system of the equipment and comprises a receiving bucket, a slewing bearing, a conveyor belt and the like. The receiving hopper is used for receiving the materials sent by the feeding conveyor belt. The rotary bearing completes the rotary motion and the supporting function of the discharging conveyor belt. The conveyor belt is used for loading and stacking. The lifting device can complete up-and-down lifting, and is suitable for loading requirements and stacking requirements of different heights. But also can complete the left and right rotary motion of the conveyor belt.
In the control of the rotation of the existing discharge conveyor belt, three control modes are adopted:
firstly, servo motor control mode adopts servo motor + speed reducer + drive gear's mode, and the advantage of this kind of mode is that control accuracy is accurate, the computer control of being convenient for. The disadvantages are large volume, limited space of installation position, and incapability of installing a high-power servo motor.
And the other is a hydraulic motor driving mode, namely a hydraulic motor and reduction gear driving mode is adopted, and the driving mode has the advantage of large driving moment. The disadvantage is not suitable for the narrow rotary position of the discharging conveyor belt and has no place for installation.
And thirdly, the motor, the turbine and the worm are adopted for pivoting support, and the driving mode is small in size and large in driving torque. The disadvantage is that the generated self-locking braking torque can not meet the technical requirement of the stopping and braking of the discharging conveyor belt. Because the mass of the discharging conveyor belt is large, the force arm is long, at the moment of stopping, the inertia force (impact force) generated by the rotation of the discharging conveyor belt acts on the worm wheel and is transmitted to the worm through the driving worm wheel (gear) of the rotating platform, the direction of the inertia force is the same as the axis of the worm, and when the impact force is greater than the strength of the fixed end cover of the worm, the fixed end cover of the worm is broken by punching.
SUMMERY OF THE UTILITY MODEL
Not enough to the above among the prior art, the utility model provides a bucket wheel dress reclaimer exit conveyor gyration hydraulic control mechanism, its compact structure, convenient operation, it is small, thrust is big.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a bucket wheel dress reclaimer exit conveyor area gyration hydraulic control mechanism, includes gyration support bearing, gyration support bearing's stationary ring is fixed on the frame, fixedly connected with connecting plate on gyration support bearing's the rotating ring, on the connecting plate and gyration support bearing's both sides be connected with the hydro-cylinder relatively, the telescopic shaft tip and the connecting plate of hydro-cylinder are articulated.
As an improvement, the end part of the oil cylinder far away from the connecting plate is hinged on the frame.
As an improvement, a pore plate for installing the rotating roller is oppositely arranged on the connecting plate.
The utility model has the advantages that:
the utility model discloses it is small, thrust is big. The volume of the hydraulic cylinder is determined by the diameter and the length of the hydraulic cylinder, so that the hydraulic cylinder is suitable for the working requirement of the bucket-wheel loading and unloading machine for discharging and rotating the material belt. Meanwhile, the pushing acting force generated by the hydraulic oil cylinder is determined by the diameter of the hydraulic cylinder and the pressure of a hydraulic system. As long as the thrust of hydro-cylinder is greater than the required thrust of conveyer belt gyration, the conveyer belt is when the gyration is stopped, and the reaction pressure in the twinkling of an eye that produces is many times operating pressure, and the pneumatic cylinder bears reaction moment ability reinforce.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.
As shown in fig. 1-2, a turning hydraulic control mechanism for a discharging conveyor belt of a bucket wheel loading and taking machine comprises a turning support bearing 1, wherein a fixed ring of the turning support bearing 1 is fixed on a frame, a connecting plate 2 is fixedly connected to a moving ring of the turning support bearing 1, oil cylinders 3 are oppositely connected to the connecting plate 2 and two sides of the turning support bearing 1, and the end parts of telescopic shafts of the oil cylinders 3 are hinged to the connecting plate 2.
The end part of the oil cylinder 3 far away from the connecting plate 2 is hinged on the frame.
And the connecting plate 2 is relatively provided with a pore plate 4 for mounting the rotating roller.
When the device is used, a hydraulic control one-way valve and an overpressure overflow valve for protecting the oil cylinder are additionally arranged in a hydraulic loop. The discharging belt needs to rotate, the oil cylinders on the same side retract by operating a control valve of a hydraulic system, the oil cylinder on the other side extends out, and the connecting plate drives the rotary supporting bearing to rotate and drives the transmission belt to rotate by an angle. The rotation angle of the conveyor belt is realized by controlling the stretching amount of the oil cylinders on the two sides.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
