Description
[technical field]
The utility model relates to a kind of escape drop device, especially the drop device used of high-rise fire-fighting life-saving.
[background technology]
Existing drop device has 2 kinds: the drop device that the rope of electrical category and non-electrical category is used in combination with buckle.
Power supply in the high-rise of disaster takes place and can be short-circuited and have a power failure in the drop device of electrical category usually, causes this class drop device not use as escaping tool.The drop device that rope is used in combination with buckle; it is metal " 8 " type structure or the metal snap close wire rope handling that utilizes drop device; rely on the frictional force of rope and drop device " 8 "; slowly descend by people's self gravitation; its advantage is: easy to carry; do not need electricity as drive energy; all be suitable for Anywhere; but shortcoming clearly: decrease speed is slower; the people of operation will pass through special training, could grasp balance control that keeps health in the decline process and the skill that descends and put rope, and it is to the protection deficiency of both hands simultaneously; can not free-handly descend, otherwise the palm of can burning.In addition, the drop device that adopts pulley to make is arranged also, difficult when it controls decrease speed in practice, thereby difficult to promote.
[utility model content]
The purpose of this utility model is, is to overcome the deficiencies in the prior art, provides a kind of safe in utilization, convenient, can flee from building disaster scene, place fast in time, reaches the drop device of protection life.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of escape drop device includes base, closes lid, and buckle of safety belt is characterized in that being provided with in base for the rope rail of rope slip and the arrestment mechanism of control drop device sliding speed; Described arrestment mechanism includes brake lever, braking rotating shaft and braking metal derby; Described braking metal derby one end is installed in the base by fixed axis, and can rotate around fixed axis.
Aforesaid a kind of escape drop device, it is characterized in that restricting rail by the top rope rail that is " ∽ " word of horizontal positioned, the middle part rope rail that the circular arc of braking metal derby inboard and the inwall of base constitute and the bottom rope rail three that is " ∽ " word of horizontal positioned be compositions partly.
Aforesaid a kind of escape drop device, the cylinder axis that it is characterized in that described braking rotating shaft is contained in the axis hole of base, and can in axis hole, rotate, one end of cylinder axis is the axis that exposes outside base, on axis, fixedly mounted brake lever, the other end of cylinder axis is a square, contacts with the outside of braking metal derby.
Aforesaid a kind of escape drop device is characterized in that also being provided with spring in the outside of braking metal derby, and the other end of spring is fixed on the base.
Compared with prior art, the beneficial effects of the utility model are: the utility model improves decrease speed, and the user is easy to control decrease speed, can free-handly descend simultaneously, can protect both hands not burnt by rope; Its cost is lower, and is safe and reliable.

[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
A kind of escape drop device includes base 1, and cover 2 is provided with rope rail 3 in base 1, and rope 4 can slide in rope rail 3, and can be by the sliding speed of arrestment mechanism 5 control ropes 4.
Be " 8 " shape on base 1 and cover 2 profiles.In base 1, be provided with rope rail 3, rope rail 3 has a plurality of bends 6, its two ends are respectively the import 7 and the outlet 8 of rope 4, after rope 4 is put in the rope rail 3, move downward at gravity effect lower bottom base 1, rope 4 can slide in rope rail 3, is skidded off by outlet 8 by way of whole rope rail 3 backs after the rope 4 of lower end slides into from import 7 simultaneously.Though the bend 6 of rope rail 3 and the rubbing action of rope 4 have certain drag effect to the slip of rope 4, along with the increasing of acceleration of gravity, gliding speed is more and more faster, and the survivor may hold and can't stand.Speed for the ease of survivor oneself control is glided is provided with arrestment mechanism 5 on base 1.
Arrestment mechanism 5 is contained in the middle part of base 1, includes brake lever 9, braking rotating shaft 10, and braking metal derby 11, fixed axis 12 and spring 13, wherein brake lever 9 is installed in the outside of base 1, and all the other all are installed in the base 1.
One end of brake lever 9 is a handgrip 14, and the other end is provided with the hole clipping 15 of opening.One end of braking rotating shaft 10 is a cylinder axis 16, and cylinder axis 16 stretches out and is axis 17; The other end is a square 18.On base 1, have axis hole, can in this axis hole, rotate after the cylinder axis 16 of braking rotating shaft 10 is put into this axis hole.With the braking rotating shaft 10 cylinder axis 16 be installed in the axis hole of base 1 after, the axis 17 of braking rotating shaft 10 is exposed at base 1 outside, hole clipping 15 with brake lever 9 is enclosed within on the axis 17 then, and will brake rotating shaft 10 with screw 19 and be clamped in the brake lever 9, if at this moment press at handgrip 14 places of brake lever 9, brake lever 9 can rotate in the axis hole of base 1 with braking rotating shaft 10.
The inboard of braking metal derby 11 is a circular arc 20, will brake metal derby 11 with fixed axis 12 and be installed in the base 1, and braking metal derby 11 can rotate around fixed axis 12; The outside 21 usefulness springs 13 at braking metal derby 11 are connected in the base 1, braking metal derby 11 is rotated counterclockwise, lean against on the corner 22 of the square 18 of braking rotating shaft 10 until the outside 21 of braking metal derby 11, this is that the utility model does not use the state that is to say when resetting, at this moment brake the circular arc 20 of metal derby 11 and just form middle part rope rail 24 with the inwall 23 of base 1, on it and the base 1, two top rope rails 25 that are " ∽ " word that are horizontal positioned of bottom, bottom rope rail 26 has constituted whole rope rail 3 together, the upper end of rope rail 3 is outlet 8, and the lower end is import 7.At rope rail 3 a plurality of bends 6 are arranged, slip within it has certain frictional resistance effect to rope 4, but increase along with acceleration, drop device possibility gliding speed is too big, at this moment will control with arrestment mechanism 5, so after pressing the handgrip 14 of brake lever 9 and allowing brake lever 9 and braking rotating shaft 10 rotate, the corner 22 of the square 18 of braking rotating shaft 10 makes braking metal derby 11 clockwise rotate around fixed axis 12 again, so the cross section of rope rail 24 upper ends 27, middle part, circular arc 20 places progressively dwindles, so braking metal derby 11 strengthens with the frictional force of rope 4, the gliding speed of drop device is slowed down on the inwall 23 that rope 4 is clamped on base 1 and stop gliding; Unclamp handgrip 14, drop device can begin again to have glided.Operation principle of the present utility model that Here it is.
With base 1, cover 2 closes, and base 1 and cover 2 is fixed together after putting on buckle of safety belt 29 respectively with four fixed screws 28 then, and it is novel just to have constituted this reality.
The utility model in use, in when, the condition of a disaster just taking place need save oneself, the rope 4 that will export 8 upper ends is earlier fastened on a certain entity in building securely, after with buckle of safety belt 29 user being tied up real fastening then, so just can slowly slide along the exterior wall of building, the user can pin handgrip 14 at any time and regulate gliding speed, so just can slide into the safety area safely.
