the utility model provides a roll lifting device, including the main gallows that is connected through rope and overhead traveling crane gib head that the level set up, the suspender of the both ends fixed connection's hoist and mount roll with main gallows, suspender lifting support on the vertical side surface of middle part articulated connection main gallows, the remote control motor of fixed connection on main gallows, one end is connected with the remote control motor and the other end is connected with the buffering rope on the top of suspender lifting support, the lower extreme of suspender lifting support is provided with the pulley that contacts with the suspender, articulated two suspender lifting supports that are connected with in the bilateral symmetry of main gallows.
The technical scheme of the utility model is further improved as follows: the main hanging bracket is rectangular, and ropes are hung at four corners of the main hanging bracket.
The technical scheme of the utility model is further improved as follows: and a pre-tightening spring is arranged in the middle of the buffer rope.
The technical scheme of the utility model is further improved as follows: the length of the part above the hinge point of the main hanging bracket on the hanging strip lifting support is smaller than the length of the part below the hinge point of the main hanging bracket on the hanging strip lifting support.
The technical scheme of the utility model is further improved as follows: the lower end of the hanging strip is fixedly connected with a rubber U-shaped ring, and the roller is sleeved in the rubber U-shaped ring.
Due to the adoption of the technical scheme, the utility model has the technical progress that:
the roller lifting device is simple, convenient and safe, meets the requirement of a roller multi-scene lifting environment, reduces labor intensity, improves operation safety guarantee capacity, integrates the advantages of a flexible lifting appliance and a rigid lifting appliance, is suitable for a roller lifting environment of compact stacking, can be automatically adapted to different lifting positions, realizes single-person safe operation without other personnel for matching with rope hanging, rope supporting and rope picking in the lifting process, can automatically adjust the lifting stress position to realize single-person operation, and realizes multi-scene, simple, convenient and safe lifting of the roller.
The flexible hanging strip is kept to be connected as a main bearing, the roller compact stacking hoisting environment is suitable, and the limitation of hard lifting appliances such as common calipers to the use environment is overcome.
The lifting mechanism is used for realizing automatic adjustment of the lifting position of the lifting belt, so that one-man operation can be realized, the complex operations of hanging a rope, holding the rope, picking the rope and the like which are generally required to be matched by multiple persons are avoided, and the original safety risk can be eliminated simply through operation.
The middle of the buffer rope is provided with a pre-tightening spring, the pre-tightening force of the pre-tightening spring can bear the gravity of the hanging strip and the bracket under no load, the pre-tightening spring is gradually straightened until the hanging strip is completely stressed in the roller hoisting process, and the tension of the buffer rope can be buffered in the hoisting process to protect the motor from being impacted.
The rubber U-shaped ring on the working surface of the hanging strip automatically opens the hanging strip when not stressed, so that the roll neck of the roll can be conveniently inserted into the middle of the hanging strip. When the force is applied, the rubber U-shaped ring deforms along with the force-applying surface, so that the effects of preventing slipping and protecting the hanging strip from being abraded are achieved.
