The present invention relates to the security module technical field of capstan winch, is especially a kind of safety device of capstan winch.
Background technology
At present the safe design of capstan winch, mainly there is overload detection, such as realize security purpose by overload-alarm, although one
Determine to improve the security that capstan winch is used in degree, but just meeting alarm, its problem for existing only when overload is reached
It is, on the one hand, the appearance of warning is sudden, and user does not have psychological preparation, therefore emergent warning easily to making
The psychology of user causes certain impact, certain discomfort can be caused, especially for new hand, in some instances it may even be possible to can cause user
In a rush after warning is received, so as to cause security incident, on the other hand, user is during capstan winch use for load
Situation of change it is unclear, for the control of capstan winch does not have initiative, be unfavorable for user play itself initiative come it is safer
Use capstan winch.
The content of the invention
The technical problem to be solved is the defect for overcoming prior art, there is provided a kind of safety device of capstan winch,
It is difficult to impact user's psychology, beneficial to user capstan winch is more safely used.
To solve above-mentioned technical problem, the present invention proposes a kind of safety device of capstan winch, and it includes power module, detection mould
