[0023] Please also read Figure 1 and Figure 2 Now, the drum steel core shaft hanger provided in the embodiment of the present application is described.

[0024] A drum steel mandrel hanger, such as Figure 1 As shown, it includes a crossbeam 1 and a hoisting mechanism 2 arranged at both ends of the crossbeam 1, the hoisting mechanism 2 is used to grab and release the drum steel core shaft, and a pulley block 3 is arranged on the top of the crossbeam 1.

[0025] The steel mandrel of the drum is grabbed and released by the hoisting mechanism 2 at both ends of the beam 1, and the hoisting machinery is connected by the pulley block 3 and the steel rope to realize the hoisting of the steel mandrel of the drum. The problem that the special cloth belt is easily damaged, resulting in major safety hazards, is solved, and production costs are saved at the same time.

[0026] In some embodiments of the present application, see Figure 1 and Figure 2 The lifting mechanism 2 includes a lifting vertical plate 21 and a movable tongue 22. The movable tongue 22 is used to be clamped with the reel steel core shaft. The movable tongue 22 is hinged to the lifting vertical plate 21 through a rotating shaft 24. The movable tongue 22 is connected to a movable tongue rotating mechanism for driving the movable tongue 22 to rotate.

[0027] The movable tongue 22 can be driven to rotate by the movable tongue rotating mechanism, so that the movable tongue 22 is engaged with the drum steel core shaft or the drum steel core shaft is released, thereby connecting or disconnecting the lifting vertical plate 21 to the drum steel core shaft, and then cooperating with the pulley block 3 to realize the lifting of the drum steel core shaft, thereby eliminating the need to use a special cloth bag, saving costs and eliminating safety hazards.

[0028] In some embodiments of the present application, see Figure 1 and Figure 2 The lifting vertical plate 21 is an inverted U-shaped structure, in the middle of which is provided with a connecting groove 27 for connecting the drum steel core shaft. There are two movable tongues 22 and movable tongue rotating mechanisms, which are symmetrically arranged on both sides of the lifting vertical plate 21. The free end of the movable tongue 22 can be extended into the connecting groove 27.

[0029] When in use, first insert the drum steel core shaft into the connecting groove 27, and the movable tongue rotating mechanism drives the movable tongue 22 to rotate. When the free end of the movable tongue 22 extends into the connecting groove 27, the movable tongue 22 can be engaged with the drum steel core shaft to limit the drum steel core shaft, thereby realizing the lifting of the drum steel core shaft. When the lifting is completed, the movable tongue rotating mechanism drives the movable tongue 22 to rotate again, so that the movable tongue 22 is reset, and the limit on the drum steel core shaft is released. At this time, the drum steel core shaft can be taken out from the connecting groove 27 to complete the entire lifting work.

[0030] In some embodiments of the present application, see Figure 1 and Figure 2 In each lifting mechanism 2, there are two lifting uprights 21. The two lifting uprights 21 are arranged in parallel and fixedly connected. A cavity for accommodating the movable tongue 22 and the movable tongue rotating mechanism is formed between the two lifting uprights 21. An opening for the movable tongue 22 to pass through is provided on one side of the cavity close to the connecting groove 27.

[0031] See also Figure 2 In some embodiments of the present application, the movable tongue rotation mechanism includes an electric push rod 23, the movable end of the electric push rod 23 is hinged to the free end of the movable tongue 22, and one end of the electric push rod 23 is hinged to the lifting vertical plate 21.

[0032] The electric push rod 23 is extended, which can drive the free end of the movable tongue 22 to extend into the connecting groove 27, thereby limiting the steel core shaft of the drum. When the electric push rod 23 is shortened, the free end of the movable tongue 22 can be driven to rotate and be stored in the cavity formed between the two lifting vertical plates 21, thereby releasing the limitation on the steel core shaft of the drum.

[0033] In some embodiments of the present application, the movable tongue rotating mechanism includes a motor (not shown) and a gear (not shown), the gear is connected to the output shaft of the motor, and one end of the movable tongue 22 near the rotating shaft 24 is an arc structure and is provided with a transmission tooth, and the gear is meshed with the transmission tooth. The gear is driven to rotate by the motor, and the gear is meshed with the transmission tooth to drive the movable tongue 22 to rotate around the rotating shaft 24, so as to limit the movable tongue 22 to the steel mandrel of the reel or release the limit on the steel mandrel of the reel.

[0034] In some embodiments of the present application, the movable tongue rotating mechanism includes a motor (not shown), a driving sprocket (not shown), a chain (not shown) and a driven sprocket (not shown), the driving sprocket is connected to the output end of the motor, the driving sprocket is connected to the driven sprocket through the chain, the driven sprocket is fixedly connected to the movable tongue 22, and the driven sprocket is coaxially arranged with the rotating shaft 24. The motor drives the driving sprocket to rotate, the driving sprocket drives the driven sprocket to rotate through the chain, and the driven sprocket drives the movable tongue 22 to rotate around the rotating shaft 24, thereby realizing the limit of the movable tongue 22 on the winding drum steel core shaft or releasing the limit on the winding drum steel core shaft.

[0035] In other embodiments of the present application, the movable tongue rotation mechanism may also adopt other structures as long as it can drive the movable tongue 22 to rotate forward and reverse, and the present application does not limit this.

[0036] In some embodiments of the present application, see Figure 2 The lifting vertical plate 21 is fixedly connected with a movable tongue support block 26 , and the movable tongue support block 26 is located below the movable tongue 22 and is used to support the movable tongue 22 .

[0037] When the movable tongue 22 rotates to the bottom, the top of the movable tongue support block 26 contacts the bottom of the movable tongue 22, the movable tongue 22 stops rotating and clamps the reel steel core shaft, and the movable tongue support block 26 provides support force for the movable tongue 22, thereby providing support force for the reel steel core shaft, which can reduce the probability of damage to the movable tongue 22 and the movable tongue rotation mechanism.

[0038] See also Figure 2 In some embodiments of the present application, the movable tongue support block 26 is fixedly connected to the hanging plate 21 through two fixing pins 25. In other embodiments, the movable tongue support block 26 can also be fixed to the hanging plate 21 through other structures, such as screws, bolts, etc., which is not limited in the present application.

[0039] See also Figure 1 In some embodiments of the present application, the crossbeam 1 is a retractable crossbeam 1. The retractable crossbeam 1 can adjust its own length, thereby adjusting the distance between the two hoisting mechanisms 2, so as to be suitable for hoisting the reel steel core shafts of different lengths.
