Referring to fig. 1-3, a high-rise escape device comprises a base 1, wherein the base 1 is horizontal, the tops of two ends of the base 1 are fixedly connected with a lower support 3, the lower support 3 is vertically upward, the top end of the lower support 3 is fixedly connected with a lower half sleeve 4, the top end of the lower half sleeve 4 is matched with an upper half sleeve 5, the top end of the upper half sleeve 5 is fixedly connected with an upper support 6, the upper support 6 is vertically upward, the top end of the upper support 6 is fixedly connected with a shaft sleeve 7, the top end of the base 1 is provided with a screw 8, the screw 8 is horizontal, two ends of the screw 8 are sleeved between the lower half sleeve 4 and the upper half sleeve 5, the screw 8 is in threaded sleeve connection with a winch 9, the screw 8 is slidably sleeved with a sleeve 10 and a spring 11, and the spring 11 is positioned at one end of the sleeve 10 far away from the winch 9, install slide bar 13 between the axle sleeve 7, just slide bar 13 is the form of being parallel to each other with screw rod 8, slide bar 13 slip cup joints pulley 14 and slider 15, the inslot solderless wrapped connection of capstan winch 9 has steel wire 19, just steel wire 19 and pulley 14 solderless wrapped connection, base 1 one side fixedly connected with fixed plate 2, just fixed plate 2 is the symmetric distribution about base 1, install stiffener 12 between upper bracket 6, just stiffener 12 is the level form, the both ends of stiffener 12 all are fixed connection with upper bracket 6, fixedly connected with connecting rod 16 between slider 15 and the sleeve pipe 10, and lie in the bottom of pulley 14 installs extension spring 18, the one end and the connecting rod 16 of extension spring 18 articulate, the one end that extension spring 18 kept away from connecting rod 16 articulates there is hangers 17, hangers 17 is fixed connection with upper bracket 6, just extension spring 18 is the symmetric distribution about hangers 17, the bottom end of the steel wire 19 is matched with a hanging basket 20, the hanging basket 20 is horizontal, the sliding rod 13, the pulley 14, the screw rod 8 and the winch 9 are arranged in a staggered mode in the vertical direction, an included angle between the sliding rod 13 and the pulley 14 and the screw rod 8 and the winch 9 is 15-20 degrees, and the steel wire rope is prevented from being in contact with the winch 9 from the pulley 14 to generate friction interference, so that the effect is influenced.

The working principle is as follows: the device is an escape device capable of automatically stabilizing the descending speed according to the load, the basic working flow of the device is that when the load appears in the hanging basket 20, the hanging basket 20 pulls the steel wire 19 to accelerate to descend, and the steel wire 19 is wound with the winch 9, so that the winch 9 is pulled to rotate when the steel wire 19 is drawn out, and the steel wire 19 is continuously released;

the descending speed of the hanging basket 20 of the device is stable in a mode that the upper half sleeve 5 and the lower half sleeve 4 of the device are in a non-locking state with the screw 8, because the steel wire 19 is wound and connected from the top end of the pulley 14 (the groove width of the pulley 14 of the device is about 8 mm, the left-right swing of the hanging basket is reduced to increase the stability when descending), the steel wire 19 applies pressure to the pulley 14 downwards, the pressure is finally acted on the base 1 through the sliding rod 13, the shaft sleeve 7, the upper bracket 6, the upper half sleeve 5, the screw 8, the lower half sleeve 4 and the lower bracket 3, so that the pressure among the components is increased, the upper half sleeve 5 and the lower half sleeve 4 tightly hold the screw 8, when the load applied to the hanging basket 20 is light, the tight holding force of the upper half sleeve 5 and the lower half sleeve 4 to the screw 8 is also small, when the load is large, the tight holding force is large, and the descending speed of different loads is balanced through automatically adjusting the friction force between the upper half sleeve 5 and the lower half sleeve 4 and the screw 8, the different loads can fall at the designed speed;

the descending speed control mode of the device basket 20 is that the steel wire 19 pulls the winch 9 to rotate on the screw rod 8 by the falling of the basket 20, the winch 9 moves along the screw rod 8 while rotating due to the thread pitch action, the device pushes the sleeve 10 to push the winch 9 reversely by the spring 11, the further rotation of the winch 9 is prevented, so as to achieve the effect of decelerating the winch 9, the same tension spring 18 further enhances the deceleration effect by pulling the connecting rod 16 and the sleeve 10 by matching with the spring 11, the descending control structure of the device basket 20 is in a dynamic balance state, when the stress of the tension spring 18 and the spring 11 is larger, the friction force of the threaded connection between the winch 9 and the screw rod 8 is increased, so that the basket 20 decelerates, when the friction force reaches a critical value, the winch 9 drives the screw rod 8 to rotate between the upper half sleeve 5 and the lower half sleeve 4 (the static friction is changed into the dynamic friction, the friction force is reduced) so that the deceleration effect of the hanging basket 20 is weakened, meanwhile, the spring 11 and the tension spring 18 are reset, the friction force of the threaded connection between the winch 9 and the screw rod 8 is reduced, the winch 9 cannot drive the screw rod 8 to rotate any more, the process is repeated, the hanging basket 20 is decelerated again, and the state has the self dynamic adjustment capacity, so that the uniform speed of the hanging basket 20 is reduced.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
