Abstract
Description
Technical Field
[0001] The utility model relates to the field of vibroseis devices, and particularly relates to a hook mechanism of a vibroseis device. Background Art
[0002] A vibroseis is a mechanical seismic source that generates seismic waves by continuously impacting the ground with a vibrator installed on a special vehicle. It is also called a continuous vibration seismic source. Since the continuous time of vibration and the change range of frequency can be artificially controlled, it is also called a controllable seismic source. In an existing technology, a vibroseis device includes a lifting mechanism, a hook, and a weight. The lifting mechanism is connected to the hook, and the hook is connected to the weight. After the lifting mechanism is released, the hook and the weight fall together, and the weight heavily hits the ground to form waves. However, in this existing technology, when the hook and the weight are connected together, the weight often causes the hook to be in a "tightened" state due to rotation, or the hook has the potential energy of rapid rotation in the natural state. This often causes the weight to be interfered when the lifting mechanism is released, affecting the accuracy of data collection by the vibroseis device. Summary of the Invention
