Abstract
The utility model particularly discloses a synchronization regulation device for moving blades of a mine fan, and solves problems that the time and labor are consumed, the consistency is low and the potential safety hazard is easily produced because the angle of moving blades of the conventional mine fan is regulated one by one. A cover plate and a driving disc which are arranged at left and right positions are sleeved on a mandrel sleeve; a plurality of sliding blocks are uniformly distributed between the cover plate and the driving disc; a crank which is connected with each sliding block and a supporting rod which corresponds to each sliding block is arranged between each sliding block and the supporting rod which corresponds to each sliding block; a driven inclined block which is slantways arranged in a vertical direction is fixed on the right side of the driving disc; the right side of the driven inclined block is provided with a driving inclined block which is matched with an inclined surface of the driven inclined block; a driving rod is fixed at the upper end of the driving inclined block; the upper part of the driving rod is connected with a regulating sleeve; and the upper part of the regulating sleeve is connected with an adjusting bolt. The device has large speed ratio and is labor-saving when the angle of the moving blades is manually adjusted; moreover, the device can self-lock and realize the synchronization regulation of the angle of the moving blades, and the regulating process is flexible and convenient; and meanwhile, the safety performance of the mine fan is greatly improved, and the device has the advantages of simple structure and convenience in operation.
Description
Technical field
The utility model relates to the mine fan controlling device, is specially a kind of mine fan movable vane synchronizing controls.
Background technique
At present; adopt shutdown and the machine of tearing open to regulate piecewise the movable vane angle to mine fan; in the adjustment process; expend a large amount of manpower and materials, generally need 2-3 hour, regulative mode is more loaded down with trivial details; and the angle of adjusting vane can not guarantee the conformity of blade angle piecewise; affect the efficient of blower fan, had simultaneously interior phenomenon without standby fan of a period of time, brought certain potential safety hazard to mine.
Summary of the invention
The utility model for solve existing mine fan regulate piecewise the movable vane angle exist waste time and energy, conformity is poor and easily produce the problem of potential safety hazard, and a kind of mine fan movable vane synchronizing controls is provided.
The utility model is to adopt following technological scheme to realize: mine fan movable vane synchronizing controls, comprise wheel hub and the uniform blade that is arranged on its outside, the center of wheel hub is provided with core sleeve, the blade inboard is fixed with pole, cover has a left side in the core sleeve, the cover plate of right setting and drive plate, uniformly between cover plate and the drive plate be provided with some slide blocks, be provided with the crank that is connected with both between each slide block pole corresponding with it, the drive plate right side is fixed with the passive skewback that above-below direction is obliquely installed, passive skewback right side is provided with the active skewback that cooperates with its inclined-plane, initiatively the skewback upper end is fixed with driveshaft, driveshaft top is connected with regulating sleeve, and regulating sleeve top is connected with adjusting bolt.
When needs are regulated mine fan movable vane angle, the rotation adjusting bolt moves up and down regulating sleeve, and then drive driveshaft and initiatively skewback move up and down, by the passive skewback of slope driving and drive plate in the axial side-to-side movement along core sleeve, thereby drive all slide blocks and drive each self-corresponding crank rotation with it, crank drives corresponding pole and blade rotary, all blades once rotate same angle, overcome existing mine fan regulate piecewise the movable vane angle exist waste time and energy, conformity is poor and easily produce the problem of potential safety hazard.
Be arranged at concentric auxiliary wheel hub in the wheel hub, pole is passed auxiliary wheel hub, and the upper cover of pole has the axle sleeve that is fixed on the auxiliary wheel hub, and auxiliary wheel hub has further guaranteed the stability of structure, and axle sleeve sets up the rotating property that has guaranteed that pole is good simultaneously.
The utility model reasonable in design is reliable, when carrying out manual tune movable vane angle, speed ratio is large, laborsaving, and can self-locking, realize the synchronization regulation of movable vane angle, adjustment process is flexible, has greatly improved the Safety performance of mine fan simultaneously, has advantages of simple in structure and easy to operate.
