Description

Technical Field

[0001] This invention relates to the field of emergency rescue technology, and in particular to an energy-consuming inertial wheel and axle escape slide. Background Technology

[0002] An escape slide is an emergency escape device primarily used for the rapid evacuation of people in emergencies such as fires. It refers to a flexible passageway where users slide down at a certain speed using their own weight. Traditional inflatable plastic slides used in places like aircraft exits require large dimensions, resulting in high costs for construction and maintenance. They are also easily damaged by sharp objects carried by evacuees, making them unsuitable for applications such as high-altitude construction work. Common playground inclined beam slides are often molded from rigid engineering plastics or fiberglass composite materials. Mold processing is difficult, and the molded modules are large in size and weight, making them difficult to transport and install within the limited space of a construction site. It is also difficult to adjust the tilt angle and installation height according to site conditions. Both types of slides use the downward force of the human body parallel to the slide surface to overcome friction and enable the human body to descend. During the process, there are often situations where the friction is too great and it is difficult to descend; or the friction is too small and the sliding is too fast, resulting in friction heat and burns to the human body. The physical and mechanical properties of the friction pairs formed by different clothing and different parts of the slide surface are very different, which may also lead to unsafe accidents such as collisions, accumulation, and pushing between people descending in front and behind.

[0003] Therefore, there is an urgent need to develop a facility or equipment that can solve the problems of difficult processing of slides, inconvenient handling during use, and difficulty in adapting to different work scenarios in the existing technology. At the same time, it can reduce the blockage caused by uneven sliding speed during the sliding process and the occurrence of heat burns caused by relative movement with the slide, thereby improving the safety of use. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide an energy-dissipating inertial wheel and axle escape slide. This solves the problems of difficult slide manufacturing and insufficient geometric adaptability in the prior art, while balancing the sliding speed of escapees on the slide and reducing the occurrence of heat burns caused by relative sliding between escapees and the slide.

[0005] The present invention discloses an energy-dissipating inertial wheel and axle escape slide, comprising a support frame and an escape slide assembly disposed on the support frame. The escape slide assembly includes a conveyor belt and an inertial shaft assembly. The inertial shaft assembly includes a first energy-dissipating inertial wheel and axle rotatably supported at a high point of the support frame and a second energy-dissipating inertial wheel and axle rotatably supported at a low point of the support frame. The conveyor belt passes around the first and second energy-dissipating inertial wheel and axles to form an escape slide.

[0006] Furthermore, the support includes uprights, horizontal bars, and diagonal bars, which are connected end to end to form a triangular structure.

[0007] Furthermore, the support also includes foundation poles disposed on both sides of the second energy-consuming inertial wheel axle. The length of the foundation poles is adjustable and lockable, so that the height of the lowest point of the support is adjustable and lockable.

[0008] Furthermore, the inclined rod is symmetrically arranged on both sides of the energy-dissipating inertia wheel axle, and is composed of two rods, one large and one small, connected together. The small rod has an adjustment groove along its length, and a nut is provided in the adjustment groove. The end of the large rod has a bolt hole, and the rod body has a tension support. The large rod and the small rod can be pressed and fixed by bolts and nuts in the adjustment groove. The large rod can be constrained to slide within the adjustment groove with a single degree of freedom to change the length of the inclined rod.

[0009] Furthermore, the uprights are symmetrically arranged on both sides of the first energy-consuming inertia wheel axle; the adjusting uprights include fixed rods and adjusting rods sleeved on both ends of the inner side of the fixed rods, the fixed rods are provided with scissor braces, and bolt holes are provided at both ends, the adjusting rods include upper adjusting rods and lower adjusting rods, the upper adjusting rods are provided with adjusting groove I, and the lower adjusting rods are provided with adjusting groove II.

[0010] Furthermore, nuts are provided in the adjusting slide I and adjusting slide II. The bolt hole at the upper end of the fixing member cooperates with the nut in adjusting slide I, so that the upper adjusting rod can be pressed and fixed in the fixing rod by bolts and the extension length can be adjusted. The bolt hole at the lower end of the fixing member cooperates with the nut in adjusting slide II, so that the lower adjusting rod can be pressed and fixed in the fixing rod by bolts and the extension length can be adjusted.

[0011] Furthermore, the crossbar is formed by crossbar I being sleeved inside crossbar II. Crossbar I is provided with a transverse adjustment groove along the length of the bar body. A nut is provided in the transverse adjustment groove. The end of crossbar II is provided with a bolt hole. The bolt hole of crossbar II cooperates with the nut in the transverse adjustment groove, so that crossbar I can be bolted and fixed inside crossbar II and the extension length can be adjusted.

[0012] Furthermore, the foundation uprights are symmetrically arranged on both sides of the second energy-consuming inertia wheel axle. The foundation uprights are formed by upright I being sleeved inside upright II. Upright I has an adjusting groove III along its length, and a nut is provided in the adjusting groove III. Upright II has a bolt hole at its end. The bolt hole of upright II cooperates with the nut in the adjusting groove III, so that upright I can be bolted and fixed inside upright II and its extension length can be adjusted.

[0013] Furthermore, the tensioning assembly includes a tensioning wheel and a cantilever shaft. The end of the cantilever shaft is provided with a ring that is sleeved on the tensioning support. The ring is provided with bolt holes. The cantilever shaft can be bolted and fixed on the tensioning support and can be constrained to slide along the tensioning support. The tensioning wheel is connected to one end of the cantilever shaft and can slide with the cantilever shaft to adjust the distance between it and the diagonal bar.

[0014] Furthermore, the two ends of the inclined rod are respectively hinged to the upper adjusting rod and the crossbar, and the crossbar is fixedly connected to the fixed rod; the first energy-consuming inertia wheel axle and the second energy-consuming inertia wheel axle are hollow wheel axles, and the hollow wheel axles can be filled with a fluid-like filler.

[0015] The beneficial effects of this invention are as follows: This invention provides an energy-consuming inertial wheel and axle escape slide. It utilizes an adjustable bracket to change the slide's geometry and a retractable conveyor belt joint to adjust the conveyor belt length, adapting to different working conditions and improving the equipment's versatility. The energy-consuming inertial wheel and axle replaces ordinary wheel and axles, adjusting the amount of filling material inside the inertial wheel to dissipate excess potential energy and regulate the sliding speed, reducing heat burns caused by relative sliding between the escapee and the slide. Furthermore, the tensioning component ensures the conveyor belt remains tensioned for an extended period, extending its service life and eliminating the need to replace the conveyor belt when adjusting the length within a small range, thus improving ease of use. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] Figure 1 This is a schematic diagram of the structure of the present invention;

[0018] Figure 2 This is a left view of the structure of the present invention;

[0019] Figure 3 This is a sectional view of the crossbar adjustment section;

[0020] Figure 4 This is the left view of the diagonal bar. Detailed Implementation

[0021] like Figures 1 to 4As shown: An energy-consuming inertial wheel and axle escape slide according to this embodiment includes a support frame and an escape slide assembly 1 disposed on the support frame 2. The escape slide assembly 1 includes a conveyor belt 101 and an inertial shaft assembly. The inertial shaft assembly includes a first sand-filled energy-consuming inertial wheel and axle 102 rotatably supported at the high point of the support frame and a second sand-filled energy-consuming inertial wheel and axle 103 rotatably supported at the low point of the support frame. The conveyor belt 101 passes around the first sand-filled energy-consuming inertial wheel and axle 102 and the second sand-filled energy-consuming inertial wheel and axle 103 to form an escape slide. Preferably, the conveyor belt 101 has a belt joint and is made of thick canvas or woven belt material with a rough surface and high strength, which can reduce damage to the conveyor belt 101 by sharp objects. The system utilizes detachable and splicable belt joints to adapt to different sliding lengths under various working conditions. The geometric dimensions of the support 2 are adjustable and lockable, meaning that the length and height of the support 2 can be adjusted according to different working conditions, improving geometric adaptability. The sand-filled energy-dissipating inertial wheel axle used in the inertial shaft group can control the wheel axle speed generated when the escaped personnel slide on the conveyor belt. Unlike the uncontrollable rotation of traditional wheel axles, this sand-filled energy-dissipating wheel axle can dissipate excess potential energy, thereby reducing the speed of the conveyor belt 101 and minimizing the relative friction between the conveyor belt 101 and the escaped personnel, thus avoiding heat burns. At the same time, the controllable sliding speed also makes it easier for the escaped personnel to quickly stand up after sliding diagonally downwards to the ground.

[0022] In this embodiment, the support 2 includes an upright 201, a horizontal bar 202, and a diagonal bar 204. The upright 201, horizontal bar 202, and diagonal bar 204 are connected end to end, forming a flag-shaped triangular structure. Compared with conventional trapezoidal or quadrilateral structures, the triangular structure has better stability. The lengths of the upright 201, horizontal bar 202, and diagonal bar 204 can be adjusted according to actual working conditions. Preferably, each component is made of lightweight small modular steel (or other lightweight alloys), which is easy to manufacture and process. The ends of each component are assembled using hinges and threads, and the quick-release structure makes it easier to stack and reduce space occupation and on-site installation.

[0023] In this embodiment, the support 2 also includes foundation poles 203 disposed on both sides of the second sand-filling energy-consuming inertial wheel axle 103. The length of the foundation poles 203 is adjustable and lockable. The lowest point of the support 2 can be supported by the foundation poles 203 and its height can be adjusted. In conventional settings, the bottom crossbar of the support 2 is almost flush with or close to the ground, which is not entirely suitable for uneven ground conditions. In this embodiment, the distance between the crossbar 202 and the ground is adjusted by the adjustable foundation poles 203, thereby improving applicability. The bottom of the foundation poles 203 is provided with pulleys, which facilitate the flexible movement of the support 2 and improve transportation efficiency. The foundation poles 203 are connected to the sand-filling energy-consuming inertial wheel axle through bushings, which will not be described in detail here.

[0024] In this embodiment, the inclined rod 204 is symmetrically arranged on both sides of the inertia axis group and is composed of two rods, one large and one small, connected together. The smaller rod 2044 has an adjusting groove 2043 along its length, and a nut is provided in the adjusting groove 2043. The larger rod 2042 has a bolt hole at its end, and the rod body is provided with a tension support. The larger rod 2042 and the smaller rod 2044 can be tightened and fixed by bolts and nuts in the adjusting groove. The larger rod 2042 can be constrained to slide freely within the adjusting groove 2043 to change the length of the inclined rod 204. The connection formed by the sleeve... The rods not only enhance their strength but also facilitate their retraction and storage. The limited space within the adjustment groove 2043 effectively restricts the rotation of the nut within it, allowing the bolt to effectively press the large rod 2042 and the small rod 2044 when screwed in. Furthermore, the nearly continuous adjustment groove 2043 offers higher precision in terms of adjustment distance and size adaptability compared to a fixed-interval adjustment method. The small rod 2044 and the rod adjustment groove 2043 are relatively easy to form and can be manufactured using tubular forming methods or assembled by segmented welding, which will not be elaborated further here.

[0025] In this embodiment, the uprights 201 are symmetrically arranged on both sides of the first energy-dissipating inertia wheel axle 102. Each upright 201 includes a fixed rod 2011 and adjusting rods sleeved on both ends of the fixed rod 2011. The fixed rods 2011 are provided with scissor braces and bolt holes at both ends. Each adjusting rod includes an upper adjusting rod 2014 and a lower adjusting rod 2013. The upper adjusting rod 2014 is provided with an adjusting groove I 2015, and the lower adjusting rod 2013 is provided with an adjusting groove II 2012. The upper adjusting rod 2014 and the lower adjusting rod 2013 have the same cross-sectional dimensions and shape. The lower adjusting rod 2013 is positioned relative to the height... The adjustment of the height is mainly to coordinate with the height adjustment of the foundation pole 203, ensuring the overall foundation level of the device as much as possible; it can also be adjusted in complex working surfaces to ensure the conveyor belt maintains a suitable angle with the ground for personnel escape. The upper adjusting rod 2014 is mainly used to adjust the effective working height of the support, so the upper adjusting rod 2014 is longer than the lower adjusting rod 2013 to adapt to higher escape and rescue scenarios; the upper adjusting rod 2014 has a connecting hole at its end, and the first sand-filling energy-consuming inertia wheel axle 102 is connected to the upper adjusting rods 2014 on both sides through the bushing and shaft set in the connecting hole; details will not be elaborated here. The scissor braces 5 are welded to the upper and lower ends of the fixed rod 2011 respectively, thus connecting them into a whole with higher integrity, reducing the number of parts and improving assembly efficiency, and the scissor braces can resist the deformation of the support in the width direction, improving the stability of the support.

[0026] In this embodiment, nuts are provided in the adjusting slide groove I 2015 and adjusting slide groove II 2012. The bolt hole at the upper end of the fixing member mates with the nut in adjusting slide groove I 2015, so that the upper adjusting rod can be pressed and fixed in the fixing rod by the bolt and the extension length can be adjusted. The bolt hole at the lower end of the fixing member mates with the nut in adjusting slide groove II 2012, so that the lower adjusting rod can be pressed and fixed in the fixing rod by the bolt and the extension length can be adjusted. The structure of adjusting slide groove I 2015 and adjusting slide groove II is consistent with that of adjusting groove. The bolt rotation can be restricted in adjusting slide groove I 2015 and adjusting slide groove II 2012, and the bolt can be constrained to reciprocate along the length direction of adjusting slide groove I 2015 and adjusting slide groove II 2012 with a single degree of freedom. The upright 201 can be adjusted by adjusting rods at both ends of the fixing rod 2011 to change the length to adapt to different working conditions at different heights, thereby improving the height applicability of the bracket 2.

[0027] In this embodiment, the crossbar 202 is formed by crossbar I 2023 sleeved inside crossbar II 2021. Crossbar I 2023 has a transverse adjustment groove 2022 along its length, and a nut 4 is provided inside the transverse adjustment groove 2022. The end of crossbar II 2021 has a bolt hole, which engages with the nut inside the transverse adjustment groove, allowing crossbar I 2023 to be bolted and fixed inside crossbar II 2021, and its extension length to be adjusted. The structure of the transverse adjustment groove is the same as that of adjustment grooves I 2015 and II 2012, and will not be described further here. The crossbars can be adjusted by bolts to change the overlap between crossbar I 2023 and crossbar II 2021 to adapt to different requirements in the length direction. The crossbars 202 and uprights 201 cooperate to change the relative angle between the first sand-filling energy-consuming inertial wheel axle 102 and the second sand-filling energy-consuming inertial wheel axle 103, that is, to change the angle between the escape slide and the ground. This ensures that the escape slide always maintains a suitable angle with the ground in different working conditions, thereby improving the safety and versatility of the equipment.

[0028] In this embodiment, the foundation uprights 203 are symmetrically arranged on both sides of the second energy-consuming inertia wheel axle 103. Each foundation upright consists of upright I 2032 sleeved inside upright II 2031. Upright I 2032 has an adjusting groove III 2033 along its length, and a nut is provided within the adjusting groove III 2033. Upright II 2031 has bolt holes at its end, which engage with the nut in the adjusting groove III 2033, allowing upright I 2032 to be bolted and fixed within upright II 2031, and its extension length to be adjusted. The structure of the adjusting groove III 2033 is consistent with that of the transverse adjusting groove 2022, and will not be described again here. The length of the foundation upright 203 is adjusted by tightening the bolts to adjust the overlap between upright I 2032 and upright II 2031, ensuring that the ground and the escape slide maintain a suitable height at all times.

[0029] In this embodiment, the tensioning assembly 3 includes a tensioning wheel 302 and a cantilever shaft 301. The end of the cantilever shaft 301 is provided with a ring that is sleeved on the tensioning support 2041. The ring has bolt holes, and the cantilever shaft can be pressed and fixed onto the tensioning support 2041 by bolts 4 and can be constrained to slide along the tensioning support 2041. The tensioning wheel 302 is connected to one end of the cantilever shaft 301 and can adjust its distance from the inclined rod 204 as the cantilever shaft 301 slides. The tensioning wheel 302 can be made of sand-filled material. The inertial wheel axle improves the overall stability and energy efficiency of the equipment. The tension support 2041 is welded to the diagonal bar 204 as a whole, which is more streamlined in structure than a separately set tensioning device. It can also reduce conflicts and interference with various moving parts in the bracket 2 with multiple size changes. The cantilever shaft 301 can be constrained by a ring to rotate with a single degree of freedom. When the length of the conveyor belt 101 is exactly matched with the escape slide, the tension wheel 302 connected to the cantilever shaft 301 can be rotated to the outside of the bracket 2 to reduce interference.

[0030] In this embodiment, the two ends of the inclined rod 204 are hinged to the upright rod 201 and the horizontal rod 202, respectively, and the horizontal rod 202 is hinged to the fixed rod 2011; the first sand-filling energy-consuming inertial wheel axle 102 and the second sand-filling energy-consuming inertial wheel axle 103 are hollow wheel axles, and the hollow wheel axles can be filled with a fluid-like filler; the members of the support 2 are connected together by hinges, making the entire support 2 highly flexible; when the sand-filling energy-consuming inertial wheel axle is set, its inner and outer diameter ratio should be between 1.2 and 1.5 to achieve a better energy consumption effect; the filler in the sand-filling energy-consuming inertial wheel axle can be filled to 1 / 2 to 2 / 3 of the wheel rim height. When the wheel axle rotates, the internal filler is driven upward and thrown down, playing an effective energy-consuming buffering role; in addition, the filler and the wheel axle together form a large mass with a large moment of inertia, making the conveyor belt accelerate more gently; and the filler can be filled on-site to reduce transportation difficulty and improve transportation convenience.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
