Abstract
The utility model relates to the technical field of a high-altitude protective device, particularly to a falling-prevention braking device. Compared with the prior art, the falling-prevention braking device of the utility model adopts a jam-on type braking mode, that is, a braking base is arranged on a slide rail, and a cam, which is hinged on the braking seat, on a brake rod, is matched with the slide rail for braking. The utility model has the advantages of simple structure, obvious using effect, high safety, operability, suitability for being used as protective devices for creeping devices, such as high-altitude ladders, fire ladders, and the like, on which slide rails can be installed.
Description
Technical field
The utility model relates to a kind of protector field, particularly a kind of fall arrest brake apparatus.
Background technology
At present, need be more and more in the occasion of high building or work high above the ground, particularly to the outer body of wall of some high-rises decorate, the operation maintenance of cleaning, higher chimney etc., all have high risk, its safety prevention measure be most important, also be the most basic guarantee.Also have the extensive application of ladders such as some high-altitude ladders, fire-fighting rack, its degree of protection requires also more and more stricter, and particularly important for operating personnel's personal safety, this just needs some safety measures and safety device.
These safety devices of the prior art generally all adopt safety rope, safety rope one end ties up on one's body the operating personnel, the other end ties up on the fixed object of high-altitude or by special personnel and controls, this safety device has advantages such as simple in structure, easy to operate, but its safe effect is poor, has unstability, defective such as cause that personnel damage easily.
The utility model content
Be to solve the defective and the weak point of fall arrest brake apparatus in the prior art high and medium ladder, the utility model provides a kind of simple in structure, fall arrest brake apparatus that result of use is preferable.
The utility model is achieved in that the fall arrest brake apparatus, it is characterized in that: comprise a Brake Block that can be slidingly matched with T font slide rail, on Brake Block, be hinged with brake bar, one end of brake bar is provided with and can withstands on the cam that plays braking action on the T font slide rail, and the other end of brake bar is provided with wiring hole.
Be provided with the T font groove that can be slidingly fitted with T font slide rail in a side of above-mentioned Brake Block, Brake Block is divided into two parts, described two parts are slidingly connected by two connecting axles, and Brake Block two parts are separately controlled by a locking device with closure along two connecting axles.
Compared with prior art, fall arrest brake apparatus of the present utility model adopts the braking mode of clamp-press type, one Brake Block is set on slide rail, cooperate braking with slide rail by the cam on the brake bar hinged on the Brake Block, it is 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 slide rail and use.
Description of drawings
Fig. 1 is the Brake Block perspective view of fall arrest brake apparatus of the present utility model;
Fig. 2 is the modular construction schematic diagram of fall arrest brake apparatus Brake Block of the present utility model when cooperating with slide rail;
Fig. 3 is the structural representations of Brake Block two parts of fall arrest brake apparatus of the present utility model when separating;
Fig. 4 is the cross section structure schematic diagram of the Brake Block of fall arrest brake apparatus of the present utility model when cooperating with slide rail.
The specific embodiment
Below in conjunction with the drawings and specific embodiments fall arrest brake apparatus of the present utility model is described further:
Referring to Fig. 1-4: be a T font groove 11 that is slidingly fitted with T font slide rail 1 in the Brake Block 10, Brake Block 10 is divided into two parts, be slidingly connected by two connecting axles 12 between two parts, Brake Block is controlled by a locking device 13 for 10 two-part separating with closure, when pressing locking device 13, this moment, two parts of Brake Block 10 can separate to both sides, can pack into the T font groove 11 of Brake Block 10 in the T font slide rail 1 like this.
A hinged brake bar 14 on the Brake Block 10, brake bar 14 1 ends have a cam 15, and cam 15 can match with T font slide rail 1, and cam 15 can withstand on the T font slide rail 1, and the other end has a wiring hole 16, can connect safety rope on the wiring hole 16.
During use, 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 wiring hole 16 of brake bar 14, when hoisting, personnel are being with safety rope upwards to draw when climbing, safety rope hauled brake bar 14 and moved upward this moment, because the bossing and the T font slide rail 1 of brake bar 14 its cam 15 when upwards drawing have certain glade plane space, do not have braking action, this moment, brake bar 14 upwards slided along T font slide rail 1 with whole fall arrest brake apparatus.When dropping downwards rapidly if operating personnel are out of control suddenly, safety rope then pulls down the outer end of brake bar 14, because the effect of lever, the other end of brake bar 14 is that cam 15 also rotates an angle, this moment cam 15 bossing being stuck on the T font slide rail 1 inflexibly just, make fall arrest brake apparatus and T font slide rail 1 relative fixed or braking, Brake Block 10 is stopped to downslide, thereby reach the purpose of safety, fall arrest.
According to embodiment of the present utility model to being illustrated property of the utility model and nonrestrictive description; but should understand; under the situation that does not break away from relevant protection domain defined by the claims, those skilled in the art can make change and/or revise.
