Fig. 1 is a schematic structural view of a hoisting mechanism in an embodiment of the present application; figure 2 is a schematic structural view of the hoisting mechanism shown in figure 1 from another perspective. For the purpose of illustration, only the structures described in connection with the present application are illustrated in the drawings.

The hoisting mechanism 100 disclosed in at least one embodiment of the present application includes a supporting member 10, a hoisting member 20, and an anti-dropping member 30. The supporting member 10 is a main body of the hoisting mechanism 100, and the hoisting member 20 is connected to the supporting member 10 for hoisting a workpiece. The anti-slip member 30 is coupled to the sling 20 for preventing the workpiece from being separated from the sling 20.

Specifically, the support 10 includes a support body 11 and a stretching portion 12. Wherein one end of the stretching part 12 is connected to the side of the supporting body 11 remote from the sling 20 and the other end is used for connecting an external lifting member.

It should be understood that, in the process of hoisting the workpiece by the hoisting mechanism 100, the workpiece can be turned many times in the suspended state, which can lead to the problem that the external hoisting member is wound and knotted, and this seriously affects the hoisting safety of the workpiece.

Therefore, in some embodiments, the support body 11 includes a support plate 111 and a rotating portion 112 axially disposed on the support plate 111, and the rotating portion 112 includes a hollow sleeve 1121 and a bearing member 1122 sleeved inside the sleeve 1121. Stretching portion 12 is rotatably connected to the inner race of bearing member 1123. In this way, in practical use, the multiple turns of the workpiece in the suspended state are converted into the rotation of the stretching portion 12 relative to the support body 11 along with the inner ring of the bearing 1123, and the winding and knotting phenomenon of the outer hoisting member does not occur.

Furthermore, in some embodiments, the external hoisting member includes a rope, an iron chain, and the like, which may be used to hoist the workpiece, and the application is not limited thereto.

The sling 20 includes a first sub-sling 21, a second sub-sling 22 and at least one sling 23, the first sub-sling 21 and the second sub-sling 22 are oppositely arranged on two opposite sides of the supporting plate 111, and a hoisting space is formed between the two at intervals. The lifting part 23 is a lifting hook arranged on the surfaces of the first sub-lifting piece 21 and the second sub-lifting piece 22 facing the lifting space, and is provided with a lifting opening 231, and the workpiece can be operatively connected to or separated from the lifting part 23 through the lifting opening 230.

In the practical application, for the work piece that the volume is great, behind hoist and mount portion 23 is gone into to the hoist and mount position card of work piece, the work piece can hold in hoist and mount space to do not influence hoist and mount operation. Therefore, the hoisting space is formed, so that the hoisting mechanism can adapt to hoisting of different workpieces, and the applicability of the hoisting mechanism 100 is improved.

At least one anti-drop member 30 is coupled to the surfaces facing the hoisting space provided to the first sub-sling 21 and the second sub-sling 22, in a number matching the number of the sling portions 23. That is, each anti-drop member 30 is correspondingly disposed at the outer circumference of each sling portion 23 and is operatively connected to or separated from the corresponding sling portion 23 to open and close the sling portion 231.

In some embodiments, each anti-falling part 30 includes an anti-falling part 31 and a limiting part 33, one end of the limiting part 33 is coupled to the corresponding first sub-sling 21 or second sub-sling 22, and the anti-falling part 31 is telescopically coupled to the limiting part 33 along a direction close to or far from the corresponding sling 23, so as to open and close the corresponding hoisting opening 231 by the anti-falling part 31.

In some embodiments, the position-limiting portion 33 has a position-limiting hole that can match with the outer diameter of the anti-dropping portion 31, and the anti-dropping portion 31 can move telescopically relative to the position-limiting hole along the axial direction of the position-limiting hole. Further, the hoisting opening 231 is located on the axis extension line of the limiting hole, and when the anti-falling part 31 extends forwards, the anti-falling part can be abutted against the hoisting part 23.

In practical application, before the hoisting position of the workpiece is connected to the hoisting part 23 or needs to be separated from the hoisting part 23, the anti-falling part 31 is retracted backwards relative to the limiting part 33, and the hoisting opening 231 is opened, so that the workpiece can be conveniently connected; in the process of hoisting the workpiece by the hoisting mechanism 100, the anti-falling part 31 extends forwards relative to the limiting part 33 until the anti-falling part 31 abuts against the hoisting part 23 to seal the hoisting port 231, so that the hoisting position of the workpiece is prevented from being separated from the hoisting port 231. Therefore, the workpiece can be prevented from falling off from the hoisting mechanism 100, and the normal unloading operation of the workpiece is not influenced.

In some embodiments, the retaining member 30 further includes an operating portion 32, and the operating portion 32 is rotatably connected to the retaining portion 31 and is controlled to drive the retaining portion 31 to extend and contract relative to the limiting portion 33.

In some embodiments, the operating portion 32 has an operating gear, and the retaining portion 31 has a retaining rack along its axial direction, and the operating gear can be engaged with the retaining rack to drive the retaining rack to move.

In the practical application, the anti-falling rack can be driven to do telescopic motion relative to the limiting part 33 through forward or reverse rotation of the operating gear, so that the anti-falling part 31 is close to the hoisting part 23 or is far away from the hoisting part 23, and the anti-falling part 31 is opened and closed on the hoisting opening 231. Therefore, the operating state of the hoisting mechanism 100 can be conveniently adjusted by an operator according to the requirement.

In some embodiments, the first sub-sling 21 can be rotatably connected to the support 10 about a first axis to rotate towards or away from the second sub-sling 22.

In particular to some embodiments, the first sub-sling 21 is hinged to one end of the support 10 and, in the path of rotation of the first sub-sling 21 with respect to the support 10, the first sub-sling 21 can be close to the second sub-sling 22 and also far from the second sub-sling 22. Therefore, the volume of the hoisting space can be changed according to different workpieces, and the hoisting adaptability of the hoisting mechanism 100 is further improved.

In some embodiments, the second sub-sling 22 can be rotatably connected to the support 10 about a second axis, to rotate towards or away from the first sub-sling 21.

In particular to some embodiments, the second sub-sling 22 is hinged to one end of the support 10 and, in the path of rotation of the second sub-sling 22 with respect to the support 10, the second sub-sling 22 can be close to the first sub-sling 21 and also far from the first sub-sling 21. Therefore, the volume of the hoisting space can be changed according to different workpieces, and the hoisting adaptability of the hoisting mechanism 100 is further improved.

In a preferred embodiment, the first sub-sling 21 can be rotatably connected to the support 10 about a first axis, and the second sub-sling 22 can also be rotatably connected to the support 10 about a second axis. Therefore, the volume of the hoisting space can be changed according to different workpieces, and the hoisting adaptability of the hoisting mechanism 100 is further improved. Where necessary, the first axis and the second axis are parallel to each other.

In some embodiments, the sling 100 further comprises an elastic element 40, the elastic element 40 comprising a first elastic element 41 and a second elastic element 42, the opposite ends of the first elastic element 41 being connected to the first sub-sling 21 and to the support 10, respectively, and the opposite ends of the second elastic element 42 being connected to the second sub-sling 22 and to the support 10, respectively, so as to provide a pre-load force for the first sub-sling 21 and the second sub-sling 22 to move towards each other, respectively.

In some embodiments, the first elastic member 41 and the second elastic member 42 may be tension springs. In the practical application, after the workpiece is accommodated in the hoisting space, the tension spring generates elastic deformation and generates elastic deformation force, the elastic deformation force has the tendency of driving the first sub hoisting piece 21 and the second sub hoisting piece 22 to be close to each other, the first sub hoisting piece 21 and the second sub hoisting piece 22 are tightly attached to the workpiece, the workpiece is pre-tightened, the workpiece can be prevented from shaking in the hoisting process, and the workpiece is prevented from falling off from the hoisting mechanism 100.

In some embodiments, the sling 20 is further provided with a force relief groove 50, and the force relief groove 50 is used for preventing the sling 20 from deforming.

In some embodiments, the force-releasing slot 50 is disposed through the lifting member 20, so as to disperse the gravity of the uniform workpiece to the whole lifting member 20, thereby preventing the resonance fracture of the lifting member 20. Therefore, the hoisting force of the hoisting mechanism 100 is improved, and accidents of workpieces in the hoisting process are effectively prevented.

As the same conception of the application, the lifting appliance is also provided, and the lifting appliance comprises the lifting mechanism 100. The lifting appliance is not easy to fall off workpieces, and the lifting safety is high.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
