Therefore, it is necessary to design a new hanger wire connection structure to solve this problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure, can reduce hoist wire rope go-between of wire rope loss.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a connecting ring for a steel wire rope of a lifting appliance is provided with a circular cylindrical frame body, the center of the frame body is provided with a through hole through which a lifting lug of the lifting appliance can pass, and the outer circumference of the frame body is provided with a groove for accommodating the steel wire rope.

Further, the bottom surface of the groove is provided with a chamfer.

Further, the groove surface is smooth.

Further, the groove width is the wire rope diameter.

Furthermore, the radian of the chamfer of the bottom surface of the groove is matched with the shape of the steel wire rope.

Further, the diameter of the through hole is such that the spreader lug just passes through the through hole.

As one embodiment, the frame body is formed by assembling two semi-rings through welding.

In one embodiment, the frame body is integrally formed.

Furthermore, the frame body is made of steel.

The beneficial effects of the utility model reside in that:

1. the utility model discloses the link structure is simple, and the preparation is convenient. The steel can be manufactured on site by utilizing waste steel materials in factories through operations of cutting, drilling, chamfering, welding and the like according to the sizes of the lifting appliance and the steel wire rope, and the manufacturing method is simple.

2. The utility model discloses the go-between can increase wire rope's lifting surface area, has slowed down wire rope radian of buckling to reduce the unit pulling force that both born in hoist and wire rope's contact point department, reduced the probability of wire rope rupture, effectively prolonged wire rope's life, reduced its consumption.

Detailed Description

To better illustrate the objects, aspects and advantages of the present invention, the present invention will be further described with reference to specific embodiments. The present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art, and the present invention will only be defined by the appended claims.

As shown in fig. 2-6, a hanger wire rope connecting ring comprises a circular cylindrical frame body 1, a through hole 2 for a hanger lug to pass through is arranged in the center of the frame body 1, and a groove 3 for accommodating a wire rope 5 is arranged on the outer circumference of the frame body 1.

The frame body 1 is made of steel. The steel can be manufactured on site by utilizing waste steel materials in factories through operations of cutting, drilling, chamfering, welding and the like according to the sizes of the lifting appliance and the steel wire rope, and the manufacturing method is simple.

Preferably, the bottom surface of the groove 2 is chamfered. The radian of the chamfer angle of the bottom surface of the groove 2 is matched with the shape of the steel wire rope 5, and the width of the groove 2 is the diameter of the steel wire rope 5. The steel wire rope 5 can be just clamped in the groove 2, and does not shake or shift in the radial direction. The surface of the groove 2 is smooth, and the friction force of the steel wire rope 5 in the groove 2 is reduced.

Preferably, the diameter of the through hole 2 enables the lifting lug of the lifting appliance 6 to just penetrate through the through hole 2, so that the lifting lug does not shake in the through hole 2, the friction between the connecting ring and the lifting lug is reduced, and meanwhile the stability of the lifting appliance is improved.

As one example, as shown in fig. 3, the frame body 1 is assembled by welding two half rings 4.

As an example, as shown in fig. 4, the frame body 1 is integrally formed.

According to the structure of the hanger 6, the connecting rings have different using methods, when the lifting lugs of the hanger 6 are in an openable and closable structure, as shown in fig. 6, the lifting lugs are opened to enable the lifting lugs to penetrate through the connecting rings, and then the lifting lugs are closed to connect the hanger 6 and the connecting rings. Then the steel wire rope 5 is sleeved in the groove 3 of the connecting ring, and the steel wire rope 5 is folded and tightened together by a fixing piece at the upper part.

When the lifting lugs of the lifting appliance 6 are of an unopenable circular ring structure, as shown in fig. 5, the connecting ring is sawed into halves, sleeved in the lifting lugs and then welded together, and then the lifting appliance 6 and the connecting ring can be connected. Then the steel wire rope 5 is sleeved in the groove 3 of the connecting ring, and the steel wire rope 5 is folded and tightened together by a fixing piece at the upper part.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
