Detailed Description

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.

The applicant has found that the main function of the conventional spreader is to provide a method of suspending and lifting common objects. The object is moved from one location to another, for example lifted from the ground to a high level, or positioned and moved in a factory, construction site, or the like. The spreader typically provides a stable support point for the object, ensuring that the object does not tilt or fall under suspension. This is a key function to ensure the safety and stability of the hoisting operation.

The applicant has further found that conventional spreaders tend to roll during handling of the drum or other cylindrical object due to the circular shape of the cylindrical object. This means that the object may rotate or slide uncontrollably, increasing the instability of the lifting operation and failing to accomplish the task of moving or placing the object. For some specially shaped cylindrical objects, additional equipment or fittings may be required to ensure stable handling. This increases the complexity and cost of the lifting operation.

To this end, the present utility model provides a hanger comprising a hanging ring 10, an iron chain 50, a rope 40 and a hanging member 30, wherein one end of the iron chain 50 is connected with the hanging ring 10; one end of the rope 40 is connected to the iron chain 50; the hanging member 30 is connected to the other end of the iron chain 50; one side of the hanging member 30 is provided with a through hole, and the other end of the rope 40 is connected to the through hole of the hanging member 30.

The eye 10 is connected to one end of the iron chain 50. This ensures that the spreader can be easily connected to the hoisting device via the hoisting ring 10. The hanger 30 is connected to the other end of the iron chain 50. The hanger 30 is provided with a through hole, and the other end portion of the rope 40 is connected through the through hole of the hanger 30. This step ensures that the rope 40 is securely attached to the hanger 30 while allowing the rope 40 to be controlled during the hoisting operation so that the iron block can enter the barrel aperture vertically during the hoisting operation and rest in equilibrium on the barrel. The lifting device solves the rolling problem easily occurring when the traditional lifting device lifts cylindrical objects, and improves the stability and safety of lifting operation. Compared with the traditional hoisting method, the novel hoisting tool does not need extra equipment or accessories to stabilize the cylindrical object, thereby reducing the complexity and cost of hoisting operation.

The connecting ring 31 in the middle of the hanger 30 provides a strong connection to tightly couple the iron chain 50 to the hanger 30. This helps to ensure that the hanger 30 is not separated from the iron chain 50 during the lifting operation, improving the safety of the operation. This connection generally reduces friction and wear between the links and the hangers 30 because they can move relatively freely in the attachment ring 31 rather than directly contacting at the surface. This may extend the useful life of the hanger 30 and the links.

The outer side wall of the lifting ring 10 is provided with two connecting lugs 11 which are arranged at intervals, and the two connecting lugs 11 are connected through a pin shaft; the chain ring of the iron chain 50 is sleeved on the pin shafts of the two connecting lugs 11.

The connecting lug 11 can rotate on the pin shaft, so that the lifting appliance has certain flexibility in lifting the cylindrical object. When the spreader is connected to the cylindrical object, the axial direction of the cylindrical object can be freely rotated, but due to the arrangement of the connection lugs 11, lateral rolling of the object is prevented.

The lifting ring 10 is connected with a lifting appliance accessory 20, the lifting appliance accessory 20 comprises a steel wire rope and a plurality of fixing components 21, one end portion of the steel wire rope penetrates through the lifting ring to be bent and folded back to form an annular structure, and the fixing components are used for fixing the steel wire rope and the steel wire rope of the folded-back portion.

The wire rope is typically a rope 40 for bearing the weight load of the suspended object, and the fixing assembly 21 is an assembly for fixing the wire rope. This step involves threading one end of the wire through the eye 10 and then folding the wire around, i.e. folding back one section of the wire itself, to form an annular region. Ensuring a very secure connection between the lifting ring 10 and the spreader attachment 20. The overlapping part of the steel wire rope is not easy to loosen or separate after being fixed by the fixing component 21, and can bear a great weight load. The connection mode provides a highly reliable hoisting method, and ensures that the hoisted object is not separated or swayed accidentally. This contributes to an improvement in the safety of the operation.

The other end part of the steel wire rope is bent and folded back to form an annular structure, and the fixing component 21 is used for fixing the steel wire rope and the steel wire rope of the folded-back part.

One end of the steel wire rope is folded back by the self-bending and overlapped with other parts of the steel wire rope to form an annular area. This area is used for connecting the spreader to the lifting device.

The fixing assembly 21 comprises a lock cylinder 212 and a lock head 211, wherein the lock head 211 is provided with two through holes, the lock cylinder 212 is provided with two end parts, and the two end parts of the lock cylinder 212 are adaptively inserted into the two through holes of the lock head 211.

The securing assembly 21 is divided into two parts, a lock cylinder 212 and a lock cylinder 211. The lock head 211 has two through holes to form two sockets. The two ends of the lock cylinder 212 are designed to fit into two through holes in the lock cylinder 211, forming a secure connection. During the lifting process, the two ends of lock cylinder 212 are inserted into the two through holes of lock head 211, forming a reliable connection point. This connection makes the connection between the spreader attachment 20 and the suspension ring 10 more secure. The structure of the lock cylinder 212 and the lock head 211 can prevent the lifting appliance accessory 20 from accidentally separating from the lifting ring 10, so that the safety of the carrying process is improved.

The lock cylinder 212 has a U-shaped cross-sectional profile. The outer side walls of the two ends of the lock cylinder 212 are provided with threads. The fixing assembly further includes a nut 213, and the nut 213 is used to limit the position of the lock cylinder 212 in the depth direction of the through hole of the lock head 211.

The U-shaped cross section of lock cylinder 212 provides space for the insertion of a wire rope into fixing assembly 21, while the threads at both ends of lock cylinder 212 mate with nuts 213, and firm fixing of lock cylinder 212 is achieved by rotating nuts 213. The threaded structures at the two ends of the core are matched with the nuts 213, the lock cylinder 212 can be quickly and simply fixed by rotating the nuts 213, and the space formed between the lock cylinder 212 and the lock head 211 can be quickly adjusted according to the thickness of the steel wire rope so as to adapt and fix the steel wire rope.

The working principle of the lifting appliance provided by the utility model is as follows: the lifting appliance comprises a lifting ring, an iron chain, a rope and a hanging piece, wherein one end part of the iron chain is connected with the lifting ring; one end of the rope is connected with the iron chain; the hanging piece is connected with the other end part of the iron chain; one side of the hanging piece is provided with a through hole, and the other end part of the rope is connected with the through hole of the hanging piece.

The hoisting operation starts and the rope is pulled, and the iron block or the hanging piece vertically enters the shaft barrel or the hole of the hoisted object. Due to gravity, the iron block or the hanging piece can be balanced against the upper cover of the shaft barrel or the hanging object, thereby preventing rolling or instability. The technical defect that the traditional lifting appliance cannot accurately control the position of a cylindrical object, the cylindrical object easily rolls when being lifted, and moving or placing of the object cannot be completed is overcome.

Other structures of a spreader according to this embodiment are known in the art.

The present utility model is not limited to the preferred embodiments, and any modifications, equivalent variations and modifications made to the above embodiments according to the technical principles of the present utility model are within the scope of the technical proposal of the present utility model.
