Abstract

The high-rise trapped people continue to move to the horizontal synchronous conveying system after landing, namely, the trapped people conveyed by the high-rise escape rope ladder need to leave the position right below the rope ladder quickly after landing so as to avoid the situation that the next person tramples the first person and needs a synchronous conveying belt to send the descending people out of several meters in time; the synchronous conveyer belt does not use power, but uses the gravity of the descending escape rope ladder to drive the conveyer belt; but also unfortunately, the resistance of the transmission conveyor belt system is assisted to achieve the speed of controlling the descending of the escape rope ladder; if the descending person leaves the position right below the vertical and quick rope ladder in time, the descending person is in danger of being stepped by the following person; only by using the synchronous conveying system, the treading of the escape rope ladder in the fast descending can be avoided, the resistance can be produced for the descending of the escape rope ladder, the descending speed is not too fast, and the difficulty of controlling the speed of the rope ladder is reduced.

Description

Continuous horizontal synchronous conveying system for trapped people in high-rise building after landing

1. The technical field is as follows: after a fire disaster occurs on the high-rise building, people on floors above the fire floor are not burned out, but are poisoned by toxic smoke, so that people above the fire point must evacuate from the floors as soon as possible; however, when a fire disaster happens and the electric Wittig is forbidden, the ladder becomes a chimney and people can not walk, and at this time, a third life passage is required to be started for escape. The escape rope ladder is also called an emergency evacuation ladder. 20-30 trapped people can be dredged to a safe floor or the ground every minute, however, after the ground is full, if descending people cannot leave the lower part of the rope ladder in time and are slow, the people who continuously and quickly get off the upper part can step on the head of the people who get off the rope ladder; therefore, a conveyor belt synchronized with the rope ladder and having synchronized handrails must be used to transport the trapped persons transported to the ground away from the position right below the rope ladder, and the farther away the person is, the better the person is, the more the person is.

2. Technical background: after the inventor invented the escape rope ladder in 2010, how to synchronously transport descending personnel away from the right below the rope ladder after the trapped personnel arrive at the ground is always considered, but the inventor does not want to do so all the time. Until now, after the model of the escape rope ladder is made, people do not want to use other power, but still use the descending power of the escape rope ladder to synchronously convey descending people away by several meters and not to be trampled by the following people.

3. The invention content is as follows: at the two ends of a pair of pulleys at the lowest end of the rope ladder or connected with the two pulley heads, a pair of multi-groove (at least each wheel is provided with more than 4 triangular belt grooves, the two grooves corresponding to the pulleys 4 are 2, the steel wire rope ladder is provided with a semicircular groove, namely, more than 4 triangular belt grooves are added on the basis of the original toothed pulley) triangular belt pulley 1, a shaft 14 is arranged at the corresponding position (the lower side of the trapped person) of the pair of belt pulleys, and the triangular belt pulley 4 is correspondingly arranged on the shaft; a pair of belt pulleys with grooves are arranged on the inward two sides of the multi-groove belt pulley 1, a pair of belt pulleys 11 are arranged above the belt, and the pair of pulley shafts cannot be directly communicated with each other, because the straight-through needs to block the steps and can only be fixed on wall bodies or plate frames on the two sides, the group of belt pulleys are handrails 10 for outputting trapped people to the outside, the highest point of the handrail is required to be missed to the main shaft direction together with the steps of the flexible ladder, namely the highest point of the handrail is longer than the positions of the steps by more than 10 cm; a plurality of small pulleys 12 are arranged in the middle and are used for pushing a handrail belt to be synchronously transmitted to a pair of large pulleys 15 beyond a few meters, namely the handrail is designed like a horizontal elevator handrail and is covered by a cover shell 10 and can synchronously run with a rope ladder and a conveying belt; the synchronous conveyer belt 7 which is used for synchronously conveying the descending personnel and the escape rope ladder for several meters is arranged at the middle part, the V difference between a circle and the upper surface of the circle between a big wheel and a big wheel can be solved just like a wrapping security inspection conveyer belt, namely, a plurality of small pulleys 13 are used for jacking the middle part, the width is the same as that of the rope ladder or slightly wider than that of the rope ladder, and about 45 centimeters exist; a corresponding belt pulley 5 is arranged below the handrail pulley several meters outside the V-belt pulley 4; in order to solve the great difference between the big round wheel and the round wheel, a thin (about 3 cm) steel pulley shaft 6 is arranged at the downward tail end of the rope ladder and forms a plane with the outward conveying belt, two ends of the steel pulley shaft are used as bearings, the conveying belt is jacked to the sole of a pedestrian in almost seamless joint with the flat ladder step, and the weight of the human body is borne by the replacement ladder step; the feet of the descending personnel are replaced and the hands of the descending personnel are also switched to the handrails in time, so the height of the handrails is set to be proper, namely the height of the handrails is about 80 cm to about 100 cm higher than the conveying belt; of course, it is also possible to use 4 to drive 5 and 11 instead of 1 to drive 11 directly; all 14 are shafts and are mounted on a wall or panel.

4. Description of the drawings: fig. 1 is a schematic view of an emergency evacuation ladder in connection with a conveyor ladder from the outside, obliquely sideways: in the figure 1, a main shaft pulley at the lower end of the escape soft ladder is used for driving a handrail and a turning driving wheel, two groups of multi-groove triangular belt pulleys or chain belt gears are additionally arranged outside an original pulley, the group of belt pulleys or chain wheels should be connected with the original pulley, or a bolt is arranged on the main shaft and synchronously runs with a main wheel, the diameter of the driving pulley should be about 1 meter, and the escape soft ladder does not collide with the upper side and the lower side of the escape soft ladder only when about 1 meter is needed; 2 is a steel wire rope of the escape rope ladder; 3 is an escape rope ladder step; 4 is a driven transmission wheel of the conveying system, the transmission wheel has two layers, the outermost layer is a plurality of belt grooves or chain gears of the main shaft of the escape ladder, and the belt grooves or the chain gears correspond to the driving wheels 1; the second layer is a belt pulley for conveying downward personnel to leave the position right below the rope ladder, and the two layers are also well synchronized by a connecting body, because the diameter of the belt pulley is equivalent to 1 to be synchronized with the rope ladder, and the length of the wheel section is equivalent to or slightly longer than that of the step; because the diameter is large and the length is large, the middle part can be sleeved on the wheels at the two ends by hollow steel pipes so as to reduce the weight and save materials; 5 is a pulley at the tail end of the continuous conveying belt, two ends of the pulley are provided with side boards, the length of the middle part of the pulley corresponds to 4, the diameter of the pulley is equal to or smaller than 4, but not too small, and the diameter of the pulley is as hollow as 4; 6, the steel shaft of the small pulley is used for pushing the man belt, and as the steel shaft is slender and has a diameter of about 3 cm, the pulley bearings are arranged at two ends, and the steel shaft pushes the belt to be close to the steps but can not be close to the steps, and resistance is generated because the steel shaft and the belt are close to each other in opposite running directions; 7 is a main conveyer belt for conveying people; 8 is a conveying hand-supporting wheel belt, and can also be driven by 4 to 11; 9 is a handrail baffle; 10 is an armrest cover; 11 is a handrail driving wheel; 12 is a small pulley under the armrest cover. FIG. 2 is an inner oblique side view of a conveying belt, and 13 is a small pulley of a flat belt at the lower top of a main conveying belt; 14 are all large pulley shafts; 15 is a handrail pulley corresponding to 11; pulleys 1, 4, 5, 11 and 15 are all about 1 m in size, 6 and 12 are smaller, the better and 13 are smaller; 16, the sliding shaft is fixedly arranged on a wall body or a plate frame.
