On the above-mentioned left clamp two sides adjacent, be respectively arranged with the rectangular teeth that staggers mutually with right clamp.

The position that above-mentioned right clamp is often opened with left clamp maintenance under the effect of back-moving spring, the shank of connection spanner remains on position up under the effect of back-moving spring.

The outstanding compared to existing technology advantage of the utility model is:

1, fall arrest brake of the present utility model adopts the braking mode of clamp-press type, cooperates with cable wire, safety rope or bonding jumper, band, automatically with fall arrest brake and cable wire or bonding jumper, with lock tight, reaches the purpose of fall arrest during tenesmus.

2, of the present utility model simple in structure, result of use is obvious, has very high security and operability, is highly suitable for some high-altitude ladders, fire-fighting rack etc. and can installs and make protector on the crawling device of cable wire, safety rope or bonding jumper, band and use.

The specific embodiment

With specific embodiment the utility model is further described below, referring to Fig. 1-16:

The fall arrest brake, include aluminum alloy body 1, enclosing cover 2 and connection spanner 15, be provided with T type through hole 101 at the middle part of described aluminum alloy body 1, there is opening 102 bottom of " I " word portion of T type through hole 101 in the side of aluminum alloy body 1, in T type through hole 101, be provided with fixing left clamp 3 and movable right clamp 6, right clamp 6 is provided with chute 62, a side that connects spanner 15 is provided with biasing post 151, shank 152 outer ends of opposite side are provided with safety rope suppending hole 1521, the middle part is positioned at the side that right clamp 6 is installed on the aluminum alloy body 1 by bearing pin 18, the shank 152 that connects spanner 15 stretches out outside the housing of aluminum alloy body 1, right clamp 6 can be on guiding pivot pin 19 left sides in the driving lower edge chute 62 of the biasing post 151 that connects spanner 15, the right slip, on connection spanner 15 and right clamp 6, be respectively arranged with back-moving

spring

16,17, back-moving

spring

16,17 the other end is suspended on the pin 14, and enclosing cover 2 can cover the opening of aluminum alloy body 1.

On the adjacent two sides of above-mentioned left clamp 3 and right clamp 6, be respectively arranged with the rectangular teeth 31,61 that staggers mutually.

The position that above-mentioned right clamp 6 is often opened with left clamp 3 maintenances under the effect of back-moving spring 17, the shank 152 of connection spanner 15 remains on position up under the effect of back-moving spring 16.

Be fixed with catch 10 by soket head cap screw 13, be used to limit the upwards rotational angle of the shank 152 that connects spanner 15.

During use, the fall arrest brake is installed in cable wire on the crawling devices such as high-altitude ladder or fire-fighting rack by arrow direction up, safety rope or bonding jumper, be with, build enclosing cover 2, one end of safety rope is tied up on one's body the operating personnel, the other end of safety rope ties up on the safety rope suppending hole 1521 that connects spanner 15, when hoisting, personnel are being with safety rope upwards to draw when climbing, safety rope hauled the utility model and moved upward by connecting spanner 15 this moment, because the position that right clamp 6 is often opened with left clamp 3 maintenances under the effect of back-moving spring 17, do not have braking action, the T font through hole 101 of whole fall arrest brake is together along cable wire at this moment, safety rope or bonding jumper, band upwards slides; When dropping downwards rapidly if operating personnel are out of control suddenly, the outer end that safety rope then will connect the shank 152 of spanner 15 pulls down, the biasing post 151 that connects spanner 15 rotates, promote that right clamp 6 is moved to the left and cooperate the fall arrest brake is fastened on the position that moment of cable wire, safety rope or bonding jumper, band falls with left clamp 3, fall arrest brake and human body are stopped to lower slider, thereby reach the purpose of safety, fall arrest.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
