On-load release device in plug-in connection

Abstract

The invention provides an on-load release device in plug-in connection based on a rotator structure. The device comprises a connecting mechanism, a release mechanism, a release operation mechanism, a protection mechanism, a signaling device and an inserted link. According to the on-load release device in plug-in connection, due to the bearing of a plurality of steel balls which can be locked and the matching of a lock sleeve, a slide sleeve, a sheave, a large spring and a small spring which are arranged in an outer cover and a flange cover, reliable connection can be realized by inlaying the steel balls into an inserted link circular groove, on-load release operation can be carried out through an external lever mechanism, and the functions of producing and releasing instantaneous trigger signals are realized. The device integrates connection and release, provides an interface which is connected with the outside, has the characteristics of compact structure, reliable connection, convenience in operation, safety and reliability, and has better universality.

Description

technical field [0001] The invention relates to a connection release device, in particular to a plug-in connection on-load release device. Background technique [0002] In occasions where it is necessary to quickly release the lifting weight, such as some test devices that need to be released when the specimen is lifted to a certain height, the general lifting load is within 1 to 2 tons, but it is required to be safely and quickly under the load state. The suspended object can be quickly separated from the lifting mechanism, and the release operating mechanism and the connecting mechanism can be integrated into one, and the operation is simple, safe and reliable. [0003] A connection and quick separation device (ZL200910031325.5) provides a non-hook-type connection and on-load separation device, which has the ability to connect quickly and conveniently and can be released under load. However, there are still some unreasonable things, such as the large size of the device, a...

Problems solved by technology

However, there are still some unreasonable things, such as the large size of the device, and the structure is not compact enough; when connecting with the external lifting mechanism, it is necessary to disassemble the upper flange sleeve first, then tighten the screws in reverse, and then connect the upper flange sleeve with the The lower flange sleeve connection; the fulcrum and resistance point of the release lever are built-in, which is inconvenient for installation and maintenance, especially when the lifting load increases to a certain value, the force required to operate the release handle increases greatly, and it may be impossible due to the excessive operating force required freed
