Description

Technical Field

[0001] The utility model relates to the technical field of life-saving soft ladders, in particular to a life-saving soft ladder for emergency rescue. Background Art

[0002] A life-saving soft ladder is a ladder used to rescue and evacuate people trapped in a fire. It is an effective tool for life-saving in critical situations when a fire or accident occurs in a building or when the staircase is blocked.

[0003] However, the top of the existing emergency rescue life-saving ladder is usually provided with a hook, and when in use, the hook needs to be hung on a nearby solid object. When the ladder is in use, there is no solid object around to hook it, it is easy for the ladder to be not firmly fixed to the windowsill, resulting in the ladder being unable to be used normally. In addition, the existing life-saving ladder is usually composed of a ladder body made of a rope and steps made of round steel pipes as main components. Since the steel pipe is sheathed on the outside of the rope and the inner diameter of the steel pipe is larger than the outer diameter of the rope, the steel pipe is easy to rotate along the outer wall of the rope when stepped on, resulting in the steps of the life-saving ladder being easy to slip when stepped on, which is not conducive to the escapee climbing along the ladder body.

[0010] Preferably, an emergency power supply is installed inside the housing, and the emergency power supply is electrically connected to the rotating motor.

[0011] Preferably, the vertical rod is connected to the horizontal wire core through a through-hole, and the steel pipe is connected to the horizontal wire core through a sleeve arrangement of the vertical rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. This life-saving soft ladder for emergency rescue, through the shell, ear plates, rotating shaft and winding drum, makes this life-saving soft ladder change from the original movable fire-fighting equipment to the fire-fighting equipment fixed at the place where the escape window is provided, and the hook at the top of the soft ladder is changed into a shell fixed on the ground, which saves the step of finding a firm object to hook before the use of the soft ladder, so as to avoid the situation that the life-saving soft ladder cannot be used normally due to the inability to find a firm object, and at the same time increase the firmness of the top of the life-saving soft ladder.

[0014] 2. This emergency rescue life-saving soft ladder uses a casing, a silicone sleeve, a horizontal wire core and a vertical rod to prevent the ladder body wire rope at the corners of the window sill from directly contacting the sharp corners of the window sill edge, thereby reducing the wear on the ladder body. At the same time, the ladder steps are not easy to rotate along the horizontal wire core due to the interweaving of the horizontal wire core and the vertical rod, thereby reducing the probability of the ladder step steel tube slipping when stepping on it, which is more conducive to escaping personnel climbing along the ladder body.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4 As shown, the life-saving soft ladder for emergency rescue in this embodiment includes an outer shell 1, and ear plates 4 are fixedly connected to the bottom of the two side walls of the outer shell 1, a vertical tube 2 is penetrated on one side of the top of the outer shell 1, and a rotating motor 5 is fixedly installed in the middle of one side wall of the outer shell 1, and a rotating shaft 6 is engaged with the output end of the rotating motor 5. The outer wall of the rotating shaft 6 is sleeved with a winding drum 17, and the outer wall of the winding drum 17 is movably wound and connected with a soft ladder body 8, a horizontal wire core 12 is fixedly connected to the middle of the soft ladder body 8, a steel pipe 11 is provided on the outer side of the horizontal wire core 12, and a plurality of vertical rods 14 are fixedly connected to the inner wall of the steel pipe 11, the outer wall of the steel pipe 11 is sleeved with a silicone sleeve 13, and the outer wall of the soft ladder body 8 is sleeved with a sleeve 9.

[0024] Specifically, the shell 1 is made of a material with good fireproof and waterproof properties, and a cavity is opened inside, so that the life-saving soft ladder can be temporarily stored when not in use. At the same time, the life-saving soft ladder can be protected during storage, so as to facilitate the storage of the life-saving soft ladder. The ear plate 4 is flush with the bottom of the shell 1. When the shell 1 is close to the ground, the ear plate 4 can also fit the ground at the foot of the wall. The function of the vertical cylinder 2 is to align the life-saving soft ladder pulled out of the shell 1, so that the life-saving soft ladder can be smoothly pulled out from the inside of the shell 1. After being energized, the rotating motor 5 can drive the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the winding drum 17 to rotate, and drives the soft ladder body 8 wound on the outer wall of the winding drum 17 to unfold, so as to facilitate the soft ladder body 8 to be taken out of the shell 1. The function of the winding drum 17 is to wind the rope of the ladder body, so as to realize the storage of the soft ladder body 8 in the shell 1. 12 is wrapped with aviation-grade steel wire with high hardness. Each section of the horizontal core 12 plus the steel pipe 11 can bear a weight of one hundred and fifty kilograms. The vertical rods 14 are vertically distributed on the inner wall of the steel pipe 11 and are perpendicular to the horizontal core 12, so that the horizontal core 12 can be interwoven and fixed with the vertical rods 14, making it difficult for the steel pipe 11 to rotate along the outer wall of the horizontal core 12, thereby reducing the probability of the steel pipe 11 slipping due to rotation when stepped on, improving the anti-slip performance of the life-saving soft ladder, and making it easier for escapees to climb. The silicone sleeve 13 is made of high-temperature resistant silicone material, which can increase the friction of the outer wall of the steel pipe 11, making the steel pipe 11 less likely to slip when stepped on. The sleeve 9 is also made of wear-resistant and fire-proof material, and the inner diameter is adapted to the outer diameter of the ladder body rope, and can form a protective layer at the junction of the rope and the edge of the window, thereby reducing the wear of the ladder body at the edge of the window.

[0025] Furthermore, a screw hole is provided at the top of the ear plate 4, and the ear plate 4 is fixedly installed at the foot of the outer wall 10 where the escape window is located through the screw hole. The outer shell 1 is fixedly connected to the outer wall 10 through the ear plate 4, and the screw hole on the ear plate 4 can pass the bolt, so that the outer shell 1 of the life-saving soft ladder can be fixed at the foot of the wall, thereby fixing the top of the life-saving soft ladder.

[0026] Furthermore, an opening 16 is provided at the top of the vertical tube 2, and the vertical tube 2 is connected to the interior of the outer shell 1. The width of the vertical tube 2 is the same as the width of the outer shell 1, so that the soft ladder body 8 can be pulled out of the outer shell 1 in an orderly manner under the traction of the counterweight block 3, reducing the probability of the soft ladder getting tangled when being pulled out.

[0027] Furthermore, the soft ladder body 8 is movably connected with the vertical tube 2 through the opening 16, and the end of the soft ladder body 8 is fixedly connected with a counterweight block 3. The function of the counterweight block 3 is to ensure that when the bottom end of the soft ladder body 8 is lowered from the window, the bottom end of the soft ladder is pulled by the counterweight block 3 and remains in a straight state, which is beneficial for the escapee to climb.

[0028] Furthermore, a magnetic strip 15 is fixedly connected to the top of the counterweight block 3, and the magnetic strip 15 is magnetically adsorbed to the vertical tube 2. After the magnetic strip 15 is magnetically adsorbed to the vertical tube 2, the end of the flexible ladder body 8 is located in the vertical tube 2, thereby realizing the storage and preservation of the flexible ladder body 8.

[0029] Furthermore, an emergency power supply 7 is installed inside the housing 1, and the emergency power supply 7 is electrically connected to the rotary motor 5. The emergency power supply 7 can enable the rotary motor 5 to be used normally in the event of an emergency power outage, thereby ensuring that the life-saving soft ladder can be used for emergency rescue and escape.

[0030] Furthermore, the vertical rod 14 is connected to the horizontal core 12 through the vertical rod 14, and the steel pipe 11 is connected to the horizontal core 12 through the vertical rod 14. The vertical rod 14 is made of metal and runs through the inside of the horizontal core 12, so that the steel pipe 11 is not easy to rotate along the outer wall of the horizontal core 12, thereby reducing the probability of the steel pipe 11 rotating when stepped on, thereby reducing the probability of the steel pipe 11 slipping when stepped on.

[0031] The method of using the present embodiment is as follows: before using the present emergency rescue life-saving soft ladder, the outer shell 1 needs to be fixedly installed at the foot of the outer wall 10 provided with the escape window through the screw holes on the ear plate 4, so that the outer shell 1 is fixed at the foot of the wall, and then the emergency power supply 7 needs to be connected to the external power supply, so that the emergency power supply 7 is in a charging state. When encountering an emergency such as a fire, the external power supply will stop charging the emergency power supply 7, so that the emergency power supply 7 starts to supply power to the rotating motor 5, and then the rotating motor 5 will drive the rotating shaft 6 to rotate, and drive the winding drum 17 to rotate, so that the life-saving soft ladder on the winding drum 17 is unfolded, and then the counterweight block 3 can be uncovered from the top of the vertical cylinder 2, so that The counterweight block 3 pulls the end of the soft ladder body 8 out of the opening 16 of the vertical tube 2, and then puts it out of the window, so that the counterweight block 3 falls naturally along the window, and then the soft ladder body 8 will slide out of the shell 1 along the vertical tube 2 in an orderly manner under the traction of the counterweight block 3. At the same time, the escapees can climb down along the drooping soft ladder body 8 through the escape window until the emergency power supply 7 is discharged. The drive motor will stop rotating, and the counterweight block 3 at the bottom of the soft ladder body 8 will stop falling. At this time, the sleeve 9 on the soft ladder body 8 will be located at the edge of the window. At the same time, the soft ladder body 8 reaches the maximum lowering length, and subsequent escapees can escape along the soft ladder body 8 after it stops.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
