Detailed description of the invention
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is schematic structural view of the invention；
Fig. 2 is that sliding block has structural schematic diagram
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
A kind of track brake falling proof device as described in Fig. 1 and 2, including fixing bolt 1, track 2, sliding block 3, fixing buckle
4 and safety rope 5, middle orbit 2 is the plate structure that cross section is rectangle, and side surface is evenly distributed with several positioning bolts 1, positions spiral shell
Bolt 1 it is uniformly distributed along 2 axis direction of track and with 2 axis vertical distribution of track, and track 2 is set by fixing bolt 1 and external climb
Standby 6 lateral surfaces are connected with each other, and 6 axis parallelly distribute on of track 2 and external climbing equipment, 2 front end face of track are evenly distributed with several ratchets
7, the uniformly distributed several circular arcs of rear end face brake guide surface 8, and each circular arc brakes guide surface 8 between two neighboring ratchet 7, and spine
7 axis of tooth and 2 axis of track are in 30 ° -60 ° angles, 8 at least 5 millimeters of high 2 front end face of errant of ratchet front end face, circular arc braking
At least 5 millimeters of high 2 rear end face of errant in 8 highest point of guide surface, sliding block 3 are rectangular block shape structure, and end face sets guide chute thereafter
31 and escape groove 32, it is interconnected between guide chute and 31 escape groove 32, and be distributed along 3 axis direction of sliding block, guide chute 31
The T-shaped groove-like structure in cross section is collectively formed with escape groove 32, sliding block 3 is coated on outside track 2 simultaneously by guide chute 31
It is mutually slidably connected with track 2,32 axis of escape groove is vertical with 1 axis of fixing bolt and intersects, fixing buckle 4 and 3 side table of sliding block
Face connection, and be located at 3 upper surface position of sliding block, 4 axis of fixing buckle and 3 axis vertical distribution of sliding block, the fixing buckle 4
It is connected with each other between safety rope 5.
In addition, the ratchet 7 is any one in the right angle bodily form, isosceles triangle and circular arc plate structure.
Present invention dismounting is quickly, structure is simple, maintenance costs are cheap, braking response is quick and it is continuous more to realize
Grade braking greatly improves the peace of high altitude operation so as to effectively provide reliable anti-fall protection to operating personnel's high altitude operation
Quan Xing.
Track in specific implementation, is passed through the rail-side surface phase of each positioning bolt and high altitude operation first by the present invention
It connects, and is distributed track and parallel track.
There is unidirectional ratchet on track, track can be fixed on the device ends such as ladder, jungle gym can be with fixing bolt
Position.Ratchet direction and centrifugal force direction are different.And the invention middle orbit, splicing when, allow two tracks at certain angle
Degree, to facilitate various installation environments, facilitates corner.
The guide chute and escape groove by track are equipped among sliding block, sliding block with track after connecting, in uplink process
In due to ratchet on track one-way, do not interfere with slide block movement, the climbing of convenient working person's uplink.In downlink process
In, operator affects safety rope after downlink a distance, and sliding block is allowed to fall.
Fall occur when, safety rope is pulled during tenesmus, since fixing buckle is mounted the unilateral of sliding block, is caused
Sliding block is bound to force unbalance and rotates, and sliding block by the circular arc of track rear end face is braked guide surface in dropping process
Guiding role makes sliding block carry out the movement of " S " type, so that ratchet of the sliding block lower end surface smoothly with track front end face is made to offset, thus
Carry out generation braking.
Simultaneously because the reason of track overall profile, it ensure that fall under any state in sliding block can be by ratchet card
Firmly, braking is generated.It can also take into account that the sliding block during uplink is smooth to be passed through.
Present invention dismounting is quickly, structure is simple, maintenance costs are cheap, braking response is quick and it is continuous more to realize
Grade braking greatly improves the peace of high altitude operation so as to effectively provide reliable anti-fall protection to operating personnel's high altitude operation
Quan Xing.
