The specific embodiment:
With reference to Fig. 1-Fig. 6, a kind of automatic falling-proof protective device of ascending a height comprises anti-falling device and guide rail.
The cross section of guide rail 1 as shown in Figure 6, for "
" shape.
Described anti-falling device comprises: a pair of " L " shape side plate 2 that is symmetrical set, one is fallen " Y " shape fore brake 3, one is fallen brake-shoe 4 and a back-moving spring 11 after " Y " shape, fore brake 3 and back brake-shoe 4 are hinged on the front upper place and the back upper place of left side plate 2 respectively by bearing pin A8, the upper end of fore brake 3 and back brake-shoe 4 is articulated and connected by bearing pin C10 and interlock plate 5 respectively, centre at interlock plate 5, be provided with safety belt rope fastening hole 12 (before the product export, be equipped with safety belt, safety belt two ends installing connector, the centre is furnished with regulating part, do not draw among the figure), the below of fore brake 3 and back brake-shoe 4 respectively is provided with left and right sides brake tooth 13, brake tooth 13 is positioned at the top of guide rail 1 and is connected with contact-making surface 15 contacts on the guide rail, the front lower place and the back lower place at side plate 2, connect end guide wheel 7 by bearing pin B9 respectively, end guide wheel 7 is connected with brake tooth 13 corresponding settings and with following contact-making surface 16 contacts of guide rail 1, back-moving spring 11 is installed on the bearing pin 8 of fore brake, its active force is between side plate 2 and fore brake 3, on the side plate 2 of described anti-falling device, be provided with side guide wheel 6, side guide wheel is installed on the hole of side plate 2 reservations by pin 14.Present embodiment, the two ends of described bearing pin A8 are fixedly connected on the left side plate 2, and fore brake 3 and back brake-shoe 4 are hinged on respectively on the bearing pin A8; Described bearing pin B9 one end is fixedly connected on the side plate 2, other end installing end guide wheel 7.
Present embodiment also can be provided with fin 19 in the lower inside of described side plate 2, and fin is connected with the side plate consubstantiality, and the height of fin is lower than the height of the upper side of end guide wheel 7.Under normal circumstances, contact-making surface 16 does not contact with fin 19 under the guide rail.But the effect of fin is: 1, lower tumbler 7 is played the preventing collision protection effect; 2, when end guide wheel 7 was destroyed, fin 19 can be held contact-making surface 16 under the guide rail, and when needs were braked, brake tooth 13 and fin 19 can tightly be clamped guide rail.
Its using method and operation principle are:
According to field condition, at first, on shaft tower, set up cat ladder, the structure and the installation method of cat ladder are same as the prior art; Secondly, generally at the right side of cat ladder installing guide rail 1, the bottom 18 of guide rail is fixedly connected on the shaft tower (do not draw among the figure).
During each ascend operation, at first, with the connector button hook at safety rope two ends on ascend operation personnel's waistband; Secondly, the anti-falling device of will packing into from the lower end of guide rail 1, as shown in Figure 1, the A direction is sure not dress instead, otherwise is drawn motionless anti-falling device up; Then, the ascend operation personnel can ascend a height along cat ladder, in the process of ascending a height, the people up, anti-falling device below, and move up along guide rail.
When the personnel of ascending a height step on when climbing toward eminence, safety rope (not drawing among the figure) will spur interlock plate 5, overcome the tension force of back-moving spring 11, fore brake 3, back brake-shoe 4 are rotated around bearing pin A8 respectively, the brake tooth 13 of brake-shoe below is improved, thereby reduce or eliminate the drag friction power of contact-making surface 15 on 13 pairs of guide rails 1 of brake tooth, anti-falling device at the uniform velocity rises synchronously with the personnel that ascend a height; As personnel of ascending a height back during descending stair, because the deadweight of anti-falling device and the acting in conjunction of pulling force A, overcome the tension force of back-moving spring 32, reduce or eliminate the drag friction power of brake-shoe equally, anti-falling device also at the uniform velocity descends synchronously with the personnel that ascend a height; When the personnel that ascend a height just in case accidentally drop or slip when eminence is fallen, safety rope changes the direction to the anti-falling device pulling force, because the pulling force when falling is or/and the effect of back-moving spring 11 tension force, the brake tooth 13 of brake-shoe below is descended, thereby increase the drag friction power of contact-making surface 15 on 13 pairs of guide rails 1 of brake tooth, brake tooth 13 and end guide wheel 7 are clamped in guide rail between the two, be that anti-falling device is fixedly clamped on guide rail 1, the personnel of ascending a height are hung on the guide rail, wait for other people come rescue or save oneself, prevent because of the generation casualty accident of falling accidentally.
