The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and principle of work.
As shown in drawings, the machine for dismounting tyre of the utility model, its organic frame (1), be the platform of circular hole (26) in the middle of having on the frame, upper rack is equipped with upper cylinder (7), the underpart of the piston rod of master cylinder is equipped with flat board (12), frame lower is fixed with down oil cylinder (22), the piston rod top of following oil cylinder is fixed with top board (27), upper rack also is equipped with fixed mount (13), the fixed mount lower end is equipped with trim ring ring (15), and small oil tank (14) also is installed on the fixed mount, and the piston rod on the small oil tank is hinged with outer claw (5).
Outer claw (5) can have a plurality of as 4.Correspondingly, small oil tank (14) also should have a plurality of as 4.Can be fixed with bevelled jacking block (28) on the top board (27),, make top board withstand on rim base smoothly, reliably to play directional tagging.
The machine for dismounting tyre of this structure can be used for monolock circle demounting of tire.During use, will treat that detaching tyre lies on the platform, wheel rim is alignd with circular hole on the platform.Handle oil cylinder down, make its piston rod drive top board and rise, when rising to when treating the detaching tyre place, top board withstands on the bottom of wheel rim (16) under the guiding of jacking block, rise thereby drive whole tire.When rising to trim ring ring place, retainer and cover tire are blocked, no longer rise, and wheel rim continues to rise.At this moment, retainer is strutted because of the tapering of wheel rim self.When the diameter of bore of retainer during greater than the wheel rim end diameter, retainer separates with wheel rim, and retainer is stuck in the trim ring ring.Handle small oil tank (14), make it drive outer claw and catch retainer, retainer and wheel rim, cover tire (17) break away from.The manipulation upper cylinder is also handled oil cylinder down simultaneously, makes flat board clamp wheel rim with top board, and drive wheel rim, cover tire descend together.When dropping to platform, cover tire is blocked on the platform, and wheel rim continues to descend under the drive of pressing plate, top board, thereby has finished the separation fully of cover tire, retainer, wheel rim.When wheel rim drops to frame lower, handle upper cylinder, make it drive flat board and get back to the initial position.Wheel rim is taken off from top board.Handle outer claw again, it is opened, retainer is released, fall.Take out retainer, cover tire is released, turned over from platform, tire dismantling work is finished.
Be fixed with collet body (29) below described flat board (12), the center prongs on the collet body (4) links together with oil cylinder (10).Center prongs has 3, rectangular distribution on collet body.Oil cylinder (10) is installed in the piston rod of upper cylinder and by connecting rod and each center prongs and links together.
The machine for dismounting tyre of this structure also can be used for monolock circle demounting of tire.During use, will treat that detaching tyre lies on the platform, wheel rim is alignd with circular hole on the platform.Handle master cylinder, make its piston rod drive collet body and be displaced downwardly to the wheel rim central hole, central control post's pawl opens it and wheel rim is caught.Handle master cylinder, make it drive whole tire and rise.When rising to trim ring ring place, retainer and cover tire are blocked, no longer rise, and wheel rim continues to rise.At this moment, retainer is strutted because of the tapering of wheel rim self.When the diameter of bore of retainer during greater than the wheel rim end diameter, retainer separates with wheel rim, and retainer is stuck in the trim ring ring.Handle small oil tank (14), make it drive outer claw and catch retainer, retainer and wheel rim, cover tire break away from.Handle master cylinder, make it drive wheel rim, cover tire decline.When dropping to platform, cover tire is blocked on the platform, and wheel rim continues to descend, when dropping to the frame bottom, and central control post's pawl withdrawal, wheel rim falls, thereby finishes the separation fully of cover tire, retainer, wheel rim.Handle master cylinder and drive the collet body rising.Handle outer claw again, it is opened, retainer is released, fall.Take out retainer, cover tire is released, turned over from platform, tire dismantling work is finished.With moving on the tire, descending, when running into the adhesion tire, top board can play a role in promoting to the wheel rim that rises on the tire topmost top board on the following oil cylinder, and retainer is separated reliably with wheel rim, cover tire in unloading process.Dull and stereotyped (12) can make one with collet body.
Oil motor (8) also is installed on described fixed mount (13), gear on the oil motor axle (9) meshes together with fluted disc (6), be fixed with on the fluted disc and dial plate (11), be fixed with manipulator oil cylinder (3) on frame, piston rod on the manipulator oil cylinder and manipulator (2) are hinged.
This is a kind of machine for dismounting tyre that can be used for the double-lock ring tire dismantling.Its operating process and last a kind of machine for dismounting tyre are basic identical.Different is to rotate the tire after being placed on the platform, so that the notch alignment manipulator on its little retainer.When master cylinder drive whole tire rise to the trim ring loop contacts after, big retainer is stuck in the trim ring ring, cover tire no longer rises, and wheel rim and little retainer continue to rise under master cylinder drives, and when rising to little retainer when parallel with manipulator, stops rising.The manipulator robot oil cylinder stretches out it and retreats in the horizontal direction after manipulator is caught little retainer, also rises simultaneously in the process that retreats, and makes the displacement on little retainer end generation level and the height, inserts between little retainer and the wheel rim so that dial plate.After dialling the plate insertion, start oil motor, fluted disc rotates under the drive of gear, dials plate and rotates, thereby little retainer and wheel rim are broken away from.Remaining action is identical with monolock circle tire.
Roller (18) is arranged on described platform (26).The existence of roller can make the side travel of tire lighter, flexible.
Side in described frame (1) is hinged with moulding bed (24), and last moulding bed middle part is hinged with the piston rod on the oil cylinder (23) that is hinged on the frame.Last moulding bed can have roller (25) near a side of frame.This is a kind of machine for dismounting tyre of going up mechanism for tire automatically that has.Tire is placed on the moulding bed, handles oil cylinder (23), its piston rod is stretched out, moulding bed swing in the drive.When being rocked to tire when parallel, promoting tire it is moved on the platform easily with platform.
Circular hole below on described platform (26) also is equipped with a plurality of rollers (30), and the setting height(from bottom) of roller reduces one by one.This is a kind of machine for dismounting tyre that wheel rim skids off device that has.Fall wheel rim on the roller (30) from collet body, tiltably landing is to ground.
Side relative with last moulding bed (24) in described frame (1) has the mechanism for tire of falling, on the mechanism for tire that falls, and the roller (20) that has equal roller (19) of a plurality of setting height(from bottom)s and setting height(from bottom) to reduce one by one, the outside of roller (20) connects moulding bed (21).This is that a kind of cover tire after separating can being pushed away easily drops down onto ground machine for dismounting tyre.Promote cover tire, it is moved on horizontal roller, when moving to tilt roller, cover tire inclination landing is to connecing on the moulding bed.
Each oil cylinder links to each other with Hydraulic Station by pipeline.The steering unit of each oil cylinder is connected on the pipeline.Upper cylinder, following oil cylinder also can be cylinder.Equally, other oil cylinders in the utility model also can be cylinder.
