Large-load automatic release mechanism

Abstract

The invention relates to a large-load automatic release mechanism. The large-load automatic release mechanism comprises a bearing frame, wherein the bearing frame is internally assembled with an outersleeve, the outer sleeve is internally equipped with an inner sleeve, a top portion of the inner sleeve abuts an inner top wall of the outer sleeve through a spring, the inner wall periphery of the outer sleeve is provided with roller grooves, the periphery of the inner sleeve is provided with roller through holes, rollers are mounted in the roller through holes, a release rod is arranged in theinner sleeve, a bottom portion of the bearing frame is fixedly connected with a base plate through a fastening member, the bearing frame is externally equipped with a hydraulic jack used for driving the outer sleeve to act, and the hydraulic jack is connected with a hydraulic oil pipeline and an electric oil pump through rapid connectors. The large-load automatic release mechanism is advantaged inthat the structure is compact, the volume is small, bearing capability is large, the hydraulic jack is controlled by the electric oil pump for action, through the outer sleeve, the inner sleeve, theroller grooves, the roller through holes and the rollers arranged in the bearing frame, automatic release of the release rod is realized, the automation degree is high, and hidden safety trouble is reduced.

Description

technical field [0001] The invention relates to the field of mechanical release equipment, in particular to a large-load automatic release mechanism. Background technique [0002] The release mechanism is a special equipment in engineering applications. Its main function is to release the specified equipment instantly according to the requirements. It has a wide range of applications in the fields of ships, impact tests, and emergency escape. In the prior art, the most commonly used structure is a structure similar to a decoupling device, which adopts the principle of leverage, and pulls the decoupling lever through a rope to perform the release action of the decoupling device. In this structure, due to the strict space requirements of the structure itself due to the principle of leverage, when releasing large-load equipment, the uncoupling device is often designed to be large in size and weight, and it is difficult to install and move. In an environment with strict requirem...

Problems solved by technology

In this structure, due to the strict space requirements of the structure itself due to the principle of leverage, when releasing large-load equipment, the uncoupling device is often designed to be large in size and weight, and it is difficult to install and move. In an environment with strict requirements on installation space and weight can not meet the requirements

In addition, the decoupling device must be decoupled by manually pulling the rope, which will cause a greater safety hazard to personnel in an emergency
