Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: it comprises support body 10 and link 11, be fixedly connected with brake box 2 on the link 11, one side of support body 10 is set with guide rail 1, guide rail 1 is inserted in the brake box 2, offer the gathering sill 4 of inclination on the opposing sidewalls of brake box 2, travelling carriage is provided with brake axle 14 in gathering sill 4, on brake axle 14, be provided with braked wheel 15, braked wheel 15 rough surface, put on the shelf at the brake box 2 of braked wheel 15 1 sides and to be provided with back pressure wheel 7, described back pressure wheel 7 relies on a sidewall bodies of guide rail 1, braked wheel 15 and back pressure wheel 7 are sandwiched in guide rail 1 wherein, be provided with brake pad 12 at braked wheel 15 another sides, the rubbing surface 19 of described brake pad 12 reduces from bottom to top gradually with the spacing of guide rail 1, end face at braked wheel 15 is fixed with ratchet 9, on the sidewall of brake box 2, be hinged with ratchet 6, the bottom of ratchet 6 withstands on the operative end surface of ratchet 9, be connected with extension spring 8 in the bottom of ratchet 6, the other end of extension spring 8 is connected on brake box 2 outer walls, the top of ratchet 6 and pull rope 17 join, the other end of described pull rope 17 is stretched out brake box 2 and is hung with working hammer 18 in this end, in brake box 2, be provided with the brake retracting spring 13 of vertical setting, these brake retracting spring 13 tops are fixed, and its bottom is connected on the brake axle 14.
Back pressure is taken turns 7 top positions and is set up the directive wheel 3 that two components are located at guide rail 1 both sides in brake box 2, and described directive wheel 3 rolls and is connected on the guide rail 1 that vertically fixedly installs.Described guide rail 1 cross section is " H " shape.The rubbing surface 19 of described brake pad 12 is 7～8 ° with the angle β of guide rail 1.Be fixed with sheave 5 in brake box 2, be provided with sheave 16 down on the link 11 of brake box 2 bottoms, described pull rope 17 is wound on sheave 5 and the following sheave 16.
Because brake box 2 is fixing with support body 10 by link 11, guide rail 1 is inserted in the centre of the directive wheel 3 of brake box 2 inside and back pressure wheel 7, braked wheel 15 to be passed through, and forms the integral body of a mutual restriction.
When support body 10 free fallings danger appears in dual roller rail clamping type falling-proof scaffold of the present invention in lifting process, working hammer 18 moment weightlessness, under the inertia force effect of the moment of working hammer 18, pull rope 17 will relax, this moment, ratchet 6 was under the effect of extension spring 8, will leave the operative end surface of ratchet 9 automatically, at this moment braked wheel 15 again under the effect of extension spring 13 brake axle 14 immediately along the guiding skewed slot 4 move and brake pad 12 wedgings, lean on left at support body 10 and brake box 2, make rubbing surface 19 push braked wheels 15, stiction between the rough surface of dependence braked wheel 15 and the rubbing surface 19 of brake pad 12 blocks support body 10, thereby make support body 10 stop tenesmus at once, reach the purpose of fall arrest.
