Anti-falling device comprises skeleton frame 10, brake-shoe 31 and braking shutoff device.Below skeleton frame, be provided with the front jocket wheel 21 and the back guide wheel 23 that adapt with the guide rail guide groove, front jocket wheel and back guide wheel are installed on the skeleton frame by front axle 22 and hind axle 24 respectively; Above skeleton frame, two pairs of hinged ears 41 are set, and the lower end of hinged ear is hinged on the inner side edge of skeleton frame by lower bearing pin 44 off-centre, and the top of brake-shoe is hinged on the hinged ear by middle bearing pin 43, the upper end of hinged ear is by upper pin 42 articulated linkage 45, and the connecting rod middle part is provided with rope fastening hole 46; Between brake-shoe and connecting rod, be provided with back-moving spring 32, the lower end of back-moving spring is fixed on the brake-shoe by screw 33.Described braking shutoff device comprises bullet pin 52 and shop bolt 53, the bullet pin is installed on the side of skeleton frame by outer cushion block 55 and interior cushion block 56, the inner of bullet pin adapts with the pin-and-hole 57 that is arranged on the brake-shoe, the outer end of bullet pin is provided with pin wheel 51, pin wheel is provided with handgrip 54, the outer end of shop bolt is fixed on the pin wheel, and the inner of shop bolt adapts with the locating hole that is arranged on the outer cushion block.
Its using method and operation principle are:
According to field condition, set up cat ladder 70 and guide rail structure; Before each ascend operation, at first, an end of safety rope is lain in the personnel's of ascending a height waistband, the other end lies on the rope fastening hole 46 of anti-falling device top connecting rod (all there is special connecting piece at the safety rope two ends); Secondly, the anti-falling device of will packing into from the lower end of longitudinal rail, with reference to Fig. 6, 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 connecting rod 45, overcome the tension force of back-moving spring, the rectangle (Fig. 5 state) that former cause connecting rod, brake-shoe, hinged ear are constituted becomes parallelogram (Fig. 6 state), the hoof of brake-shoe below is descended, promptly increase the distance between hoof and the skeleton frame, when described distance during greater than the guide-track groove wall thickness, eliminate the drag friction power of brake-shoe, 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, 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 32 tension force, make former cause connecting rod, brake-shoe, the parallelogram that hinged ear constitutes becomes rectangle immediately, the hoof of brake-shoe below is risen, promptly reduce the distance between hoof and the skeleton frame, brake-shoe and skeleton frame will be clamped on the guide rail cell wall, be that anti-falling device is fixed on the guide rail, 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.
When the personnel of ascending a height arrive that a certain height need move horizontally or during operation, at cross slide way and longitudinal rail infall, can change anti-falling device over to cross slide way from longitudinal rail by the guide rail conversion equipment: anti-falling device is moved to exchange joint 65; Rotation rolling disc 64 makes the exchange joint connect cross slide way; Anti-falling device can be moved to the left or move right as required; Because cross slide way is horizontally disposed with and the effect of brake-shoe hoof, anti-falling device will can not produce derailing and fall phenomenon, for guarantee that anti-falling device moves flexibly on cross slide way, anti-falling device is provided with the braking shutoff device: pull-up pin wheel 51, make shop bolt 53 break away from outer cushion block 55, and rotation handgrip 54 makes pin wheel 91 clockwise rotate 90 degree (cushion block is provided with the fixedly locating hole of pin wheel outside, has two locating holes, does not draw among the figure); Depress connecting rod 45, the hoof of brake-shoe is descended, because brake-shoe is provided with pin-and-hole 57, the bullet pin can insert pin-and-hole automatically, and anti-falling device is in the braking closed condition, as shown in Figure 6.This moment, anti-falling device can move freely on cross slide way.
When coming and going to cross slide way and longitudinal rail infall when fulfiling assignment, enable brake apparatus for preventing that the truck work personnel from forgetting, connecting on the chassis 63, be provided with baffle plate 66, has only pull-up pin wheel 51, and rotate handgrip 54 and make pin wheel 51 toward back rotation 90 degree, anti-falling device could continue to move into exchange joint 65.Because pin wheel 51 is enabled brake apparatus, as shown in Figure 5 immediately toward back rotation.Reach purpose of safety.
Present embodiment is also in the termination of guide rail, promptly in the lower end and the upper end of longitudinal rail, the left end of cross slide way and right-hand member all are provided with the anti-falling device dead lock, and dead lock is unidirectional dead bolt (not drawing among the figure), its purpose is to prevent that anti-falling device is unexpected derailed, guarantees safety.
Embodiment 2, the described automatic falling-proof protective device of ascending a height of this example also comprise cat ladder 70 structures, guide rail structure and anti-falling device.
Compare with embodiment 1, its difference only is anti-falling device.This routine described anti-falling device is on the basis of embodiment 1 described anti-falling device, sets up the built-in pulley 25 of guide rail, and built-in pulley is installed on the pulley support 26, and pulley support is fixedly connected on skeleton frame 10 rear end downsides.As shown in Figure 12 and Figure 13.The effect that the built-in pulley of guide rail is set is to reduce the resistance that anti-falling device moves on guide rail.
All the other structures of present embodiment are corresponding identical with embodiment 1; Its using method is also identical with operation principle, the Therefore, omited.
