The inventors have found that a heavy duty tire is composed of a cover, an inner tube and a rim strip. The outer tire consists of three main parts, namely a tire body, a tire tread and a tire bead, wherein the tire body is formed by laminating a plurality of layers of rubberized cord fabrics according to a certain angle, and the cord fabrics are usually made of high-strength steel wires and synthetic fiber rubberized fabrics; the tread contacts with the ground and is made of heat-resistant and shear-resistant rubber materials; the tyre bead is used for tightly fixing the tyre on a wheel rim, and mainly comprises a steel wire ring, triangular filling rubber and steel wire ring wrapping cloth. The tire tread of the waste heavy-duty tire casing is usually close to the completion of abrasion, only the casing and the tire bead part are left, the casing part is usually deformed and damaged in different degrees due to abrasion, tire burst and the like, but the tire bead cannot be deformed and kept complete, the reason is that the steel wire ring formed by the high-strength steel wire and the filling rubber can bear various interaction forces of the casing and the rim, and the tire casings of different specifications can be sorted and sorted by measuring the diameters of the tire beads because the tire beads are not deformed and damaged.

The inventor finds that the waste heavy-duty tire casings are generally collected by a maintenance point, stacked in various specifications when the casings are replaced, and then the waste heavy-duty tire casings in each storage yard are conveyed to a crushing processing point by a dumper. To realize efficient crushing, the waste heavy-duty tire casings of various specifications need to be pre-arranged, namely, the waste heavy-duty tire casings which are unloaded by a dumper and stacked in a disordered manner are arranged into workpieces of the same specification and the diameter of the tire bead is convenient to measure.

The inventor finds that the tire bead of the waste heavy-duty tire casing cannot deform and keep complete, tires of various specifications can be sorted by measuring the diameter data of the waste heavy-duty tire casing, the conventional optical wave, acoustic wave and electromagnetic wave range finders are selected, and the key factor influencing the measurement accuracy of the diameter of the tire bead is the positioning of a sensor, namely two positioning points for measuring the diameter cannot be easily found on the tire bead. If any point of the tire bead of the waste heavy-duty tire is fixed to enable the tire bead to naturally droop, the gravity line of the tire bead is coincident with the diameter line of the tire bead, two sensor positioning points for measuring the diameter of the tire bead can be found easily by utilizing the principle, namely when the waste tire is suspended, the testing arm starts from the suspension point of the fixed tire bead and searches downwards along the direction of the gravity vertical line, and the distance between the positioning point and the suspension point obtained by blocking the lower edge of the tire bead is the diameter of the tire bead.

The inventor finds that based on the measurement principle, the problems can be solved by designing a grabbing and lifting conveying slide rail, a hanging rail grabbing and lifting mechanism and a roller sorting slide frame, wherein the grabbing and lifting conveying slide rail ensures the upright working state of the waste tire during grabbing and lifting, the grabbing and lifting conveying slide rail comprises a limiting slide rail, a mechanical arm, a railing and a belt conveyor, the waste tire is in the upright state when entering the belt conveyor after being pre-arranged, the mechanical arm adjusts the distance between the upper limiting slide rail and the lower limiting slide rail and the railing according to the height of the waste tire, and adjusts the distance between the limiting slide rail and the railing according to the width of the waste tire, so that a slide way consisting of a pair of limiting slide rails and a pair of railings is formed, and the railings for preventing the waste tire from being conveyed by the static friction force provided by the belt conveyor adopt a simple support structure, namely a fixed hinge support at one end, the other end of the movable hinged support is specifically designed into a cylindrical mode to reduce the friction area, and the limiting sliding rails on the two sides of the upper portion can be operated by a manipulator to achieve a floating contact state with the waste tires. The manipulator is designed to solve the problem that the waste tires topple over when standing, and therefore the manipulator is designed with a pair of inclination angle connecting rod assemblies and a pneumatic connecting rod assembly, the purpose that the cane on two sides below is limited and the limiting slide rails on two sides above are in floating contact with the waste tires is achieved through the cooperation of the inclination angle connecting rod assemblies and the pneumatic connecting rod assembly, the maximum inclination angle of 2 degrees is allowed for the cane and the limiting slide rail on any side relative to a vertical plane, namely the inclination angle connecting rod assembly and the pneumatic connecting rod assembly which exceed any side later compensate the other side. The cane and the limit slide rail are designed to be parallel and keep a certain distance, so that the clamping jaws can be conveniently closed and extend into the tire bead for gripping; the suspended rail grabbing mechanism comprises an annular suspended rail, a self-walking trolley, a jaw assembly and a tire bead diameter testing device, wherein a straight section of the annular suspended rail is parallel to a grabbing and lifting conveying slide rail and a roller sorting slide frame, the jaw assembly is hung on the self-walking trolley, the grabbing and the sorting of the waste heavy-duty tire casing are realized by the operation cycle along the annular suspended rail, a centering taper sleeve is wedged into a limiting slide rail to complete the positioning during the grabbing and the lifting, under the control of an operating arm, a pair of jaws are closed and extend into a tire bead, the self-walking trolley drags the tire to move along the limiting slide rail through the jaw assembly until the tire is separated from the limiting slide rail and enters a bent section of the annular suspended rail, the tire is in a free suspension state, the gravity line and the diameter line of the tire bead diameter testing device are coincident, a telescopic hydraulic cylinder is driven to drive a testing arm to reach a positioning point for measuring the diameter of the tire bead, thereby judging the specification of the tire, and sending the tire into a roller way sorting sliding frame for sorting with the help of a self-walking trolley; during sorting, the centering taper sleeve is guided in by the guide rail to be positioned and accurately moves to the position above the roller way sorting sliding frame, under the control of the control arm, the clamping jaws are opened, waste tires fall into the rotary roller way, the waste tires are kept in an upright state under the help of loose leaves, the stepping motor drives the gear set, the rotary roller way is rotated by a certain angle under the help of the plane bearing to align to the turnover rail trolley collecting the waste tires with corresponding specifications, the rotary roller way continues to work to send the waste tires into the carrier roller group on the rail trolley, the pair roller ratchet wheel drives the clamping rods to fold and clamp the waste tires to be kept in an upright state, and the rail trolley sends the waste tires into an appointed station along the straight reciprocating movement of the.
