Description
Technical field
The present invention relates to a kind of catching device, more particularly to a kind of multi-functional anti-fall descending lifeline.
Background technology
With science and technology it is growing, social is showing improvement or progress day by day, work high above the ground, heavy duty service content become much and frequency
Numerous, contingency also constantly occurs therewith, and this safety prevention measure of personnel in operation process that just works work high above the ground carries
More strict requirements are gone out.
Catching device also known as speed difference automatic controller, it is that one kind can reach locking falling object position limiting apart from interior fast braking
The instrument put, it can effectively protect the life security of work high above the ground operating personnel, prevent work high above the ground operating personnel high-altitude
Fall, while also have major and immediate significance in fields such as metallurgical automobile making, petrochemical industry, engineering constructions.
However, the catching device to circulate in the market has following defect：First, exist without slow drop function, operating personnel
Often human body is caused damage because impulsive force is excessive in drop event, can not effectively ensure the safety of operating personnel.
2nd, existing catching device hangs low pattern often by high, and operating personnel can not adjust decline in real time according to the needs of oneself
Speed, mobility is poor, the strong influence usage experience of user.3rd, existing catching device base after use
All there is no automatic wire winding function in sheet, cotton rope withdraws the use that can be influenceed during processing next time in the winding for not passing through rule,
And then the service life of catching device can be influenceed, it is impossible to reach the purpose for ensureing operating personnel's safety.
The content of the invention
The present invention, without slow drop function, low mode operations, operation is hung often by high for existing catching device
Personnel can not adjust decrease speed in real time according to the needs of oneself, mobility is poor, the strong influence use of user
Experience, and there is no automatic wire winding function, the winding that cotton rope cannot pass through rule is withdrawn, and has a strong impact on use next time, and then
A kind of the defects of influenceing the service life of catching device, there is provided new multi-functional anti-fall descending lifeline.
In order to solve the above-mentioned technical problem, the present invention is achieved through the following technical solutions：

Formed and be rotatablely connected with the lid 5 centered on central shaft 4, in addition to Buffer Unit 13, handle assembly 8, braking parts, it is described slow
Rush component 13, braking parts are arranged in the built-in space, when safety rope 2 rapidly pulls out, the rotating part 9 and the braking
Portion is engaged to form stopping, when swing handle component 8, the handle assembly 8 drive the Buffer Unit 13 with it is described
Rotating part 9 is inconsistent to form slow drop state.
In use, first the outer end suspension of safety rope 2 is fixed on a certain fixing point, then pulling handle component 8 causes
Buffer Unit 13 and rotating part 9 are inconsistent to form slow drop state, now in the presence of user's self gravitation, rotating part 9 with
Start to rotate relative to lid 5 centered on central shaft 4, so as to allow user by the present invention can with certain speed it is slow under
Drop, ensure that stability when user is landed from high-altitude；And when user quickly drops suddenly because of fortuitous event, safety
Rope 2 will be pulled out rapidly, and now rotating part 9 will be engaged to form stopping rapidly with braking parts, so as to prevent user after
It is continuous descending, effectively ensure the life and health of user.Similarly, when user under slow drop state and wants to rest on a certain
During height, rotary handle is only needed to release slow drop state, now safety rope 2 is also rapidly pulled out in the presence of user's gravity,
Rotating part 9 is caused to be engaged to form stopping rapidly with braking parts, so as to realize the mesh that user is fixed on to a certain height
's.
Pass through above structure so that slow drop function is combined by the present invention with anti-drop function well, is effectively avoided
User in drop event because impulsive force is excessive and to human body it is hurtful it is unexpected occur, and user can will be anti-fall
Descending lifeline, which is taken, to be taken with oneself, can control lapse rate at any time, meets the needs of people well, is easy to the popularization in market.
Preferably, the rotating part 9 is ratchet, the ratchet outer is provided with ratchet 91, and the braking parts include spine
