Abstract
A rope anti-topple device for a suspension descending system aims to overcome the shortcoming that operation is affected as a free end of a rope (one end of the rope freely droops to the ground) slides downwards under the action of gravity when the rope is loosened from a hand of an operator whether the operator lifts up the rope or pulls down the rope when an existing personal board-type sling is used. By the aid of a unidirectional rotating part running on a sliding rail rope groove in clinging manner, the gyration radius of a unidirectional rotating component is larger than the distance between a gyration center and a sliding rail rope, the sliding rail rope is tightly compressed when the unidirectional rotating component gyrates, the unidirectional rotating part normally rotates when the rope runs upwards, the unidirectional rotating part reversely stops when the rope runs downwards, and the unidirectional rotating component gyrates until the rope is tightly compressed by the aid of friction force generated between the unidirectional rotating part and the rope.
Description
Technical field
The present invention relates to a kind of suspention decline system, relate in particular to a kind of with human body self weight be gravity, the rope tilting prevention device of suspention decline system by hand control.
Background technology
In daily, usually use the single suspender of using of seat board formula during cleaning outer wall, during use, at first select a fixedly place of fastening rope at the roof place, with all ropes take the angle, take rib, at the bottom of the place of taking eaves uses rubber pad, in case the friction wear lifting rope; To beat what a special knot in the drop device on the present formula boatswain chair of lifting rope again.Because such one special knot is arranged, so at work, boatswain chair can be toward not gliding, and the people controls rope, can free operant.Briefly, when rope up, boatswain chair just toward gliding a bit, carry what sliding what, carry and how soon how soon sliding, until end-of-job.External rendering engineering in high-altitude also can be used this instrument.Because when using suspender, the user of service also will carry out constructing operation together except operation rope descends, owing to be aloft work, therefore work has certain danger.The single suspender high-altitude application of use seat board formula person must be the male citizen over 18 one full year of life, and through physical examination and safety method training, can operation through passing the examination, the workman is pre-job must not to drink, and has uncomfortable symptom such as flu just must suspend aloft work.The single advantage with suspender of seat board formula is simple in structure, and is easy to operate, if safety measure is done thoughtfully, it is very high to use safety.
For standard works, the title of each type component is quoted the pertinent data of " the single suspender technical specification of security of Cleaning for Outer Wall of Building operation seat board formula " herein.Suspention decline system mainly is made up of working rope, drop device, adaptor union, seat apparatus.Drop device: be installed on the working rope, with operating personnel's own wt be power, device by hand control; The kind of drop device comprises now: bar type, multi-plate, Eight characters ring type and unload button, and wherein unload the button drop device and be commonly called as U-shaped crab button.Adaptor union: the internal system part can be linked together, have the ring parts of normally closed valve.Seat apparatus: take advantage of the device that carries the operating personnel, formed by suspender belt, lining band and seat board.
Because the seat board formula is single to be to beat what a special knot in drop device with suspender, and utilize the weight of lower end rope self will tie tension, seat board and human body are fixed and are suspended in the air, when needs descend, the operator must up carry the special end rope of forging, described special knot is not tightened up, and at this moment, human body descends, how many ropes carries, how many human bodies glides, and how soon rope is carried, and how soon human body glides.When depth of building was very high, rope needed very long, and at this moment, the weight of rope is also very big, and when rope surpassed 100 meters, the weight of rope will be above 25 kilograms, and up rope will have certain difficulty.For this reason, I developed a kind of employing down the method for pulling cord realize the suspender that human body descends.But, no matter be up rope or down pulling cord, when staff unclamps rope, free-ended rope (freely hanging down to an end rope on ground) will slide downwards under the effect of gravity, the influence operation.
Summary of the invention
The seat board formula is single with suspender in use now in order to overcome, no matter the operating personnel is up rope or down pulling cord, when staff unclamps rope, free end (freely hanging down to an end rope on ground) will slide downwards under the effect of gravity, the problem of influence operation, the present invention proposes a kind of rope tilting prevention device that suspends the decline system in midair, it utilizes the unidirectional rotation part of being close to the rope operation, when rope upwards moves, unidirectional rotation part normal rotation, when rope moved downwards, the reverse check of unidirectional rotation part stoped the rope inverted running.
The technical scheme that technical solution problem of the present invention adopts is, a kind of rope tilting prevention device that suspends the decline system in midair that the present invention proposes, comprise the slide rail that is fixed on the adapter plate, permanent seat, at least one unidirectional rotation assembly, the unidirectional rotation assembly is mainly by the unidirectional rotation part, wheel shaft, wheel seat, axis of revolution constitutes, described unidirectional rotation part is installed on the wheel seat by wheel shaft, the unidirectional rotation assembly is installed on the adapter plate by axis of revolution, rope passes through from slide rail, the unidirectional rotation part is close on the slide rail rope, the radius of turn of unidirectional rotation assembly is greater than the distance of center of gyration to the slide rail rope, during the revolution of unidirectional rotation assembly, the slide rail rope is with compacted, when rope upwards moves, unidirectional rotation part normal rotation, when rope moved downwards, the reverse check of unidirectional rotation part, the Mo Chali that produces between unidirectional rotation part and the rope caused the revolution of unidirectional rotation assembly until rope is compressed.
One of preferred version of the present invention: described slide rail is provided with the grooving that holds rope.
Two of preferred version of the present invention: described grooving is provided with anti-slide opening.
Three of preferred version of the present invention: be coated with anti-skidding glue-line on the described unidirectional rotation part external cylindrical surface.
