[0029] As shown in Figures 1-8 The utility model discloses a device of quick replacement rubber roller, including bridge crane 1, the chain 2 of bridge crane is hung below the boom 3, the boom is by the upper straight section rod body 4, lower straight section rod body 5, left vertical section rod body 6 interlocking solid and is composed " C " character shape structure, the C shape opening of boom is oriented as left and right, to facilitate the lateral access of the aluminum tape 8 that rubber roller 7 is wound, be provided with the bandage 9 on the lower straight section rod body, to bind rubber roller.

[0030] In the utility model embodiment, the top of the upper straight section rod body is fixedly provided with a circular connecting ring 10, and the bottom of the chain is hung on the connecting ring.

[0031] In the utility model embodiment, the upper straight section rod body and the lower straight section rod body are both cylindrical rod bodies.

[0032] In the utility model embodiment, the middle region of the lower straight section rod body is coaxially provided with a rotating roller 11.

[0033] In the utility model embodiment, the outer diameter of the rotating roller is greater than the outer diameter of the lower straight section rod body.

[0034] In the utility model embodiment, the outer periphery of the rotating roller is wrapped with a rubber sleeve 12.

[0035] In the utility model embodiment, the lower straight section rod body is provided with an axial limiting assembly of the bandage on the left and right sides of the left and right ends of the rotating roller.

[0036] In the utility model embodiment, the axial limiting assembly includes a left limiting convex ring 13 and a right limiting convex ring 14 which are coaxially fixed to the lower straight section rod body, and a ring groove 15 between the left and right limiting convex rings is used to wind the top of the bandage.

[0037] In the embodiment of the utility model, the outer circumferential part of the left and right limiting convex rings is wrapped with rubber sleeves, and the maximum outer diameter of the left and right limiting convex rings wrapped with the rubber sleeves is less than or equal to the maximum outer diameter of the roller wrapped with the rubber sleeves.

[0038] In the embodiment of the utility model, the outer end part of the C-shaped opening of the boom is screw-connected with a detachable sealing plate 16, so as to close the C-shaped opening when needed.

[0039] In the embodiment of the utility model, the working principle of the device for quickly replacing the rubber roller is as follows:

[0040] 1, the equipment is stopped, and the horizontal, longitudinal and vertical movements of the boom are controlled by the bridge crane. When the boom is close to the aluminum belt, manual hand holding is assisted to hold the boom, the boom is translated rightwards along the lateral direction of the front side of the aluminum belt, and the aluminum belt is located in the boom.

[0041] 2, the old rubber roller and the rubber roller in the rear transmission direction continue to keep still, the equipment controls the old rubber roller to continue to drive the rubber roller in the front transmission direction for a predetermined small distance, so that the aluminum belt on the old rubber roller is in a loose collapsed state.

[0042] 3, the position of the boom is adjusted to align the aluminum belt with the middle region of the rubber sleeve of the roller, then the boom is slightly lifted to lift the aluminum belt, and then the boom is translated towards the old rubber roller, at this time, the rubber sleeve of the roller contacts the bottom surface of the aluminum belt and rolls with the bottom surface of the aluminum belt, so as to avoid scratching the aluminum belt.

[0043] 4, after the boom is translated to the upper side of the old rubber roller, the old rubber roller with the removed screw is bound on the lower straight section rod body by a binding belt, and the top of the binding belt is wound in the annular groove between the left and right limiting convex rings, so as to avoid axial displacement.

[0044] 5, the boom with the old rubber roller is synchronously lifted, workers assist to slightly lift the aluminum belt arranged in the boom upwards, so that the aluminum belt does not contact the boom, and then the boom is translated leftwards to retreat from the aluminum belt, and the old rubber roller is synchronously taken out.

[0045] 6, the aluminum belt loses the support of the old rubber roller and the boom, and is temporarily collapsed on the work station. The boom retreated from the aluminum belt is locked on the C-shaped opening by workers, the C-shaped opening is closed, and the C-shaped opening plays an insurance role, so as to avoid that the binding belt is taken out of the boom. Subsequently, the old rubber roller is hoisted to other work stations by the boom to replace a new rubber roller.

[0046] 7, the replaced new rubber roller is hoisted back by the boom, when the boom is close to the aluminum belt, manual hand holding is assisted to hold the boom, and workers lift the collapsed aluminum belt upwards, so that the boom is translated rightwards along the lateral direction of the aluminum belt, and the aluminum belt is located on the rubber sleeve of the roller in the boom again.

[0047] 8. The crane places the new rubber roll in its installed position, locks the new rubber roll, removes the straps, and the crane withdraws from the aluminum strip. The equipment is operated to tighten the aluminum strip and wrap it around the new rubber roll.

[0048] The movement of the crane in the above steps is controlled by the bridge crane.

[0049] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments. However, any simple modification, equivalent change and modification of the above embodiments made without departing from the technical content of the present application, and in accordance with the technical essence of the present application, still falls within the protection scope of the present application.
