Abstract
The utility model relates to an anti-falling device for people when people are in high places, which is a safety device used for preventing the falling of people working in high places when people are in the process of the movement of climbing, transposition and return. The utility model comprises a purpose-made climbing ladder and an anti-falling device which is sheathed on a right upright post of the purpose-made climbing ladder, wherein, the anti-falling device can be moved upwards and downwards along the right upright post of the purpose-made climbing ladder. One end of the body of the anti-falling device is a bended hook whose middle part is in the shape of a circular arc, and the right upright post of the purpose-made climbing ladder is enclosed by the circular arc. The distance between the top end of the bended hook and the top end of a pin post is smaller than the diameter of the right upright post and is larger than the diameter of a stepping right end during work. A small pulley wheel on the lateral surface of the bended hook can be bounced out to enable the anti-falling device to be clamped on the right upright post. The anti-falling device is connected to a safety belt, which can guarantee the safety of people in high places.
Description
The staff that the utility model relates to a kind of work high above the ground is a kind of falling proof device of ascending a height ascending a height, prevent in transposition and the moving process that returns the protective device that falls specifically.
The truck work personnel can tie up to safety belt on the firm member when work high above the ground, play the effect that prevents that the high-altitude from falling.But ascend a height, fall arrest safeguard protection problem in transposition and the moving process that returns still do not have solution.Because the psychology and the influences of other unfavorable factors,, make staff's safety be subjected to serious threat ascending a height, in the moving process of transposition, easilier causing falling of the personnel of ascending a height.
The utility model purpose be exactly for solve above-mentioned truck work personnel when the work high above the ground and ascending a height, fall arrest problem in transposition and the moving process that returns, a kind of falling proof device of ascending a height is proposed, guarantee truck work personnel's safety, can not fall.
The utility model purpose is realized by following technical scheme: this falling proof device of ascending a height, include a special cat ladder or special rod member, one is enclosed within on special cat ladder right column or the special rod member and can be along right column or the upper and lower mobile anti-falling device of special rod member, special cat ladder is formed by saving in last joint, following joint and the 3-20 joint, left column and middle being equipped with of right column at cat ladder are marked time, and the support member that is used to be connected on the high structure is housed in the cat ladder side; Anti-falling device one end is a crotch shape, in the middle of the crotch is circular shape, penetrate the right column or the special rod member of special cat ladder, opening edge at crotch stretches out a bearing pin, distance between bearing pin top and the crotch top is when operation, diameter less than special cat ladder right column or special rod member, can be by the supporter of mark time on the special cat ladder right-hand member or special rod member, a truckle is housed in the crotch side, can rotate around pulley spindle, the pulley below has spring to withstand on the pin, and the distance that pulley ejects is regulated with nut in the pin lower end.
Connect with connector between the left column of the special every joint of cat ladder, use two-way Bolt Connection between right column or the special rod member: promptly be welded with left-handed nut and right-handed nut respectively in a last right column lower end and next right column upper end, between use two-way Bolt Connection, the diameter of connection place is identical with every joint right column or special rod member diameter, makes that anti-falling device can be upper and lower mobile and not interrupted along right column or special rod member.Bearing pin is used the handle permanent position, after rotating 90 °, handle stirs handle, during the compression spring, pin can upper and lowerly move, and distance can be inserted in anti-falling device right column or take out from right column greater than the diameter of special cat ladder right column or special rod member between adjusting pin axle head point and the crotch end points, when operation, adjust distance less than the right column diameter, and 90 ° anti-falling device can not come off from right column the handle commentaries on classics, and can move along right column is upper and lower.Distance between anti-falling device crotch and the bearing pin end points can guarantee upper and lower to mark time and special rod member supporter by special cat ladder smoothly when mobile.
During use, the personnel that ascend a height are linked together with safety belt and anti-falling device, turning handle, pressing spring is regulated bearing pin downwards, and crotch partly is enclosed within on the right column of special cat ladder, bearing pin rebounds, turning handle makes bearing pin and crotch end-point distances less than the right column diameter, and can be by marking time and support member and pinning.Anti-falling device is placed right hand top, and when ascending a height, anti-falling device is upwards promoted by the right hand, moves up, and truckle rotates along right column.Fall just in case accidentally drop, truckle is ejected by spring, and owing to action of gravity, anti-falling device is stuck on right column or the special rod member again, and the people can not drop down.
The utility model advantage is a compact conformation, and is in light weight, easy to loading and unloading, easy to use, self-locking property is good, and is solid and reliable, and the truck work personnel use, just in case accidentally drop or slip, the generation casualty accident of can not falling is ascend operation personnel's an a kind of reliable falling-proof safety device.
