Separable combined lifting ring with self-locking structure and using method

Abstract

The invention discloses a separable combined lifting ring with a self-locking structure and a using method. The separable combined lifting ring comprises a lifting ring body, a safety buckle and a lifting hook. The safety catch is arranged on the inner side of the hanging ring, one end of the safety catch is hinged to the hanging ring, a reset device is arranged between the safety catch and the hanging ring and enables the other end of the safety catch to be attached to the hanging ring all the time, the attached area of the hanging ring and the other end of the safety catch is a hanging ring groove, a connecting area is arranged below the hanging ring groove, and the size of the hanging ring groove is smaller than that of the connecting area. The diameter of the circular ring is larger than or equal to the size of the connecting area, the circular ring of the lifting hook is nested on the connecting area of the lifting ring, and the size of the lifting hook notch is larger than or equal to the size of the groove of the lifting ring and smaller than the size of the connecting area. When combined hanging is carried out, hanging safety is guaranteed, and hanging and disassembling actions can be efficiently and conveniently executed.

Description

technical field [0001] The invention belongs to the field of hanging loading and unloading, and relates to a detachable combined suspension ring with a self-locking structure and a use method. Background technique [0002] When the helicopter is suspended and transported, the connecting parts between the cargo and the helicopter are affected by stall, vibration, aerodynamic force and inertial force. , improve the safety of hanging flight. When hanging and loading and unloading, a certain lifting point needs to be connected with multiple lifting points, such as multi-leg assembly slings, multi-leg lifting chains and hanging nets, etc., and combined lifting rings are often used for single-point and multi-point connections. In order to ensure the economy of external suspension flight and minimize the preparation time for hanging and disassembling cargo, the combined lifting ring should be quickly disassembled and assembled. In practical application, both sides of the combined...

Problems solved by technology

[0003] At present, most of the ground-mounted combination rings used in the fields of machinery, metallurgy, petrochemical, and ports are non-removable primary and secondary rings, or are indirectly connected by intermediate parts such as shackles and double-ring buckles. The weight is heavy and the connection steps are cumbersome.

At the same time, in order to prevent the cargo from falling off during the hanging flight in a complicated environment, fasteners, cotter pins or pins are used for anti-loosening measures. Not only special tools and spare parts are required for anti-loosening, but also the connection process takes up a lot of hanging preparation time
