First purpose of the present invention provides a kind of catching device, it does not need extra attachment rail, and anti-fall brake structure is simple, second purpose of the present invention provides a kind of catching device with self-help escape function, it is except can reaching first purpose, can also after the braking of falling, make the personnel that rescued slowly drop to ground and need not wait for rescue.Catching device of the present invention comprises rotating mechanism, arrestment mechanism and bindiny mechanism, and said mechanism is encased by housing.
Above-mentioned housing comprises base plate and panel.
Above-mentioned rotating mechanism comprises two bearing pin and scroll wheel assemblies that are fixed in base plate of being fixed in base plate, this scroll wheel assembly comprises the reeded rolling disk of roller and edge, roller and rolling disk unitary rotation, itself and rolling disk can be that one is fixed, the activity that also can be split links, there is a passage that direction is vertical with the axle center of roller this roller inside, this passage is preferably through the axle center, this channel interior is provided with two block a and b, wherein block a is fixed on an end of passage, retaining is determined b then can be free movable in passage, connects with extension spring between two blocks, and roller is static or when slowly running, the outer surface of block b is in roller inside, when the roller high speed rotating, centrifugal force overcomes the pulling force of extension spring, and the outer surface of block b is stretched out outside the roller.
Above-mentioned arrestment mechanism comprises arrestment mechanism 1, and this arrestment mechanism 1 comprises block c, ejector pin and spanner.Wherein, block c is arranged on outside the roller circumference and is fixed on the housing, ejector pin can be one and be arranged on block c one side, also can be two and be arranged on the both sides of block c, ejector pin penetrates housing outside housing, and its top (towards the enclosure interior direction) can also be provided with return spring, block c and ejector pin are on the horizontal plane with the passage of roller, spanner is arranged on the ejector pin bottom, ejector pin can be pressed in the housing, and described spanner can be a decenter clutch.Above-mentioned arrestment mechanism can also comprise arrestment mechanism 2, and this arrestment mechanism 2 comprises the locking pincers and tightens up handwheel.The locking pincers can be made by the material of various high frictional force, asbestos friction sheet for example, it is shaped as the circle that has fracture, and have the power handle that is connected as a single entity with round on one side of incision position, the circular portion of locking pincers is enclosed within on the roller, and its position is not blocked block b and got final product, tighten up handwheel and outside housing, penetrate housing, its top is relative with the power handle of locking pincers, can be provided with between the two to tighten up spring or directly contact, tightens up and can mark the scale that expression tightens up degree on the handwheel.
Above-mentioned bindiny mechanism comprises the rope and the collar.Rope can be the high strength cord that reaches the lifesaving standard arbitrarily, steel wire rope for example, chemical fibre-cotton synthetic fibre silk rope etc., this rope is wrapped in the groove of rolling disk of scroll wheel assembly, the mode that cut with interior public affairs at the two ends of rope is respectively through two bearing pins and stretch out outside the housing, under the lockup state, the maximal friction of rope and rolling disk and the internal common tangent of bearing pin and rolling disk and rope homonymy are relevant with rope stretches out direction angulation and rope from housing material, weight when this maximal friction should be greater than people's body weight or other concrete application, to use steel wire rope to be example, the angle ranging from the 5-60 degree, preferred 15-50 degree, more preferably 30-45 degree.The collar is fixed on the housing.
Description of drawings
Fig. 1 is the construction profile of falling-prevention self-rescue escape device of the present invention.
Fig. 2 is the sectional structure chart of falling-prevention self-rescue escape device of the present invention when static or roller slowly run.
Fig. 3 is the sectional structure chart of falling-prevention self-rescue escape device of the present invention when the roller high speed rotating.
The specific embodiment
Further the present invention will be described below in conjunction with accompanying drawing and exemplary embodiment
The present invention in use, on one of rope 17 fixing pinnacled fixture, the other end is placed on the outside with suitable length in mode arbitrarily, by the collar 20 device of the present invention is fixed on one's body the personnel.When personnel's low speed descended, device of the present invention was along with personnel descend synchronously, this moment bearing pin 9 and rolling disk 7 low speed rotation under the drive of rope 17, one side rope 17 fixing be in hemicompact or low amount of redundancy state always.When falling when meeting accident, the acceleration that falls makes rope 17 drive rolling disk 7 rotation at a high speed, at this moment, the pulling force that the centrifugal force of block b in the roller 5 of synchronous high-speed rotation overcomes extension spring 18 stretches out outside the roller 5, by the rapid block of block c, realize the braking of roller 5 and rolling disk 7, because the fixed edge of rope 17 is in hemicompact or low amount of redundancy state always, therefore, the impulsive force of braking is limited.At this moment, the quilt that suspends in mid air is rescued personnel and can be screwed in housing and tighten up handwheel 13, directly act on or act on the power handle of locking pincers 4 by tightening up spring 10, thereby make locking pincers 4 tightly vise roller 5, then, pulling decenter clutch 14 is pressed into ejector pin 11 in the housing, with block b top rollback wheel 5, at this moment, personnel still are suspended in the air by the braking of locking pincers 4, then, will tighten up handwheel 13 according to the scale on it and unclamp a little, personnel promptly can drop to ground with lower speed, realize saving oneself.
