Description
Technical field
The utility model relates to a kind of suspention decline system, relate in particular to a kind of with the body own wt be gravity, suspention decline system through hand control.
Background technology
In daily, cleaning outer wall is with the single suspender of using of seat board formula, selects a fixedly place of fastening rope earlier 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; Again with beating what a special knot in the drop device on the present formula boatswain chair of lifting rope.Because such one special knot is arranged, so at work, boatswain chair can be toward gliding, and the people controls rope, can free operant, briefly, when up rope, 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.Using the single suspender high-altitude application of 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, and the workman is pre-job must not to drink, and has uncomfortable symptom such as flu just to 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 " among this paper.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 through 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 type crab and buckle.Adaptor union: can the internal system part be linked together, have the ring parts of normally closed valve.Seat apparatus: take advantage of the device that carries the operating personnel, form by suspender belt, lining band and seat board.
Because the single suspender of using of seat board formula is in drop device, to beat what a special knot, and utilizes the weight of lower end rope self will tie tension, and seat board and human body are fixed and are hung in the air; When needs descended, the operator must up carry the special end rope of forging, and said special knot is not tightened up; At this moment, human body descends, and how many ropes carries; How many human bodies glides, and how soon rope is carried, and how soon human body glides.Along with the continuous decline of human body, when human body was overhead nearer, the weight of the following rope of said special knot was more and more littler, and therefore the tightening force to special knot is also just more and more littler, need not upwards rope this moment, and human body just possibly descend fast, meets accident easily.
The utility model content
For overcome now the seat board formula single with suspender when overhead near; Special knot possibly skid and cause unexpected problem, the utility model to propose a kind of suspention decline system, and it sets up bottle gouard moved by hands and through rope-winding wheel of bottle gouard moved by hands control; Said rope-winding wheel is provided with the grooving that holds rope; Rope after the special knot is wrapped on the rope-winding wheel with crossing the rope formula, and the grooving on the rope-winding wheel makes between rope and the rope-winding wheel has friction force, prevents that rope from skidding on wheel; When the hand control bottle gouard moved by hands, when bottle gouard moved by hands rotated, rope-winding wheel rotated, and rope is raised, and human body descends, and how many ropes is raised, and how many human bodies descends; When bottle gouard moved by hands stopped operating, rope-winding wheel also stopped operating, and human body stops to descend; Through manual operations, human body can descend gradually; Because bottle gouard moved by hands has reverse check brake function; Even under the effect of human body gravity; Rope-winding wheel can not active rotation; Guaranteed that the rope after the special knot produces pulling force to special knot, overcome human body and overhead more and more closely caused the rope problem more and more littler that it is out of control to guarantee that the decline process can not take place to the tightening force of special knot; Can prevent accident by actv..
The technical scheme that the utility model technical solution problem adopts is; A kind of suspention decline system that the utility model proposes; Mainly comprise working rope, drop device, adaptor union, take advantage of and carry device that said working rope is stamped a special knot on drop device, it is characterized in that; The anchor fitting that bottle gouard moved by hands, rope-winding wheel also are set, is used to install and fix; Said bottle gouard moved by hands is controlled said rope-winding wheel and is rotated, and said rope-winding wheel is provided with the grooving that holds rope, and the working rope after the special knot is wrapped on the grooving of said rope-winding wheel with crossing the rope formula; Said anchor fitting mainly comprises attaching parts, bearing, rope-winding wheel wheel shaft, the axle bed of rope-winding wheel wheel shaft is installed, and said axle bed is fixed on the bearing, and rope-winding wheel is installed on the rope-winding wheel wheel shaft, drives rope-winding wheel when the rope-winding wheel wheel shaft rotates and rotates; The splined hole gear of said bottle gouard moved by hands is connected with rope-winding wheel wheel axle mounting, drives the rope-winding wheel wheel shaft when splined hole gear rotates and rotates with rope-winding wheel.
The utility model prompting; Rope-winding wheel is installed on the rope-winding wheel wheel shaft; Be in order to realize that the rope-winding wheel wheel shaft drives the purpose that rope-winding wheel rotates; Its connection mode can adopt bolted connection or key to connect, and also can adopt other known connection mode, just can meet the demands as long as its connection can make the rope-winding wheel wheel shaft drive the rope-winding wheel rotation.
