Hook release mechanism

Abstract

The invention provides a hook release mechanism. The hook release mechanism comprises a release bracket, a connecting pedestal and a release sliding disk, wherein a release trigger pulley is positioned at the bottommost end of an inclined plane of a release trigger inclined plate and a hook and a hanging shaft are buckled together when the release sliding disk is positioned at an upper limit position of the release bracket; when the release sliding disk slides downwards relative to the release bracket, the inclined plane of the release trigger inclined plate squeezes the release trigger pulley, so the hook rotates around a supporting shaft and is gradually separated from the hanging shaft. Automatic release of the hook at any position is realized, the hook is firmly buckled, the release is flexible, the release force is extremely small (only the rolling friction force of the hook and the hanging shaft is overcome), the release effect angle is small (smaller than 30 degrees), and the problem existing in buckling and release of the hook of an existing non-power impact seismic source instrument is more effectively solved.

Description

technical field [0001] The invention belongs to the field of shallow seismic exploration and relates to a seismic source instrument, in particular to a hook release mechanism. Background technique [0002] With the rapid development of urban construction, environmental geological survey, mineral exploration and engineering quality inspection, the requirements for shallow seismic exploration are getting higher and higher. Shallow seismic exploration, as an important method of geophysical exploration, has great impact on the country Construction and national economic development has made great contributions. [0003] Shallow seismic exploration is mainly to detect underground geological problems such as rock fractures, loess layer structure, aquifer, bedrock depth and distribution, engineering geological conditions, and stratum conditions within hundreds of meters underground. The basic principle of detection is to artificially generate a seismic wave source, the seismic wave...

AI Technical Summary

Problems solved by technology

[0007] In the existing non-electromechanical shock sources, there are still deficiencies in the fastening and release of the active shock parts, A) can not be released at any position; B) if the fastening is firm, it is difficult to release, if the release is sensitive, the fastening It is too unreliable; C) In the release process of the general hook, not only the friction between the hook and the shaft of the impact piece must be overcome, but also the pressure generated by the unreasonable bending of the hook must be overcome. It requires a large release force to release, and sometimes it is even difficult to release
