Description

Technical Field

[0001] This utility model relates to the field of rescue equipment, and in particular to a multi-purpose curved and straight rescue ladder. Background Technology

[0002] In high-rise buildings, industrial facilities, mines, and other similar locations, rapid evacuation and rescue in emergencies are crucial for ensuring life safety. Traditional rescue equipment, such as fire escape staircases and fixed rescue ladders, while meeting evacuation needs to some extent, often suffers from limitations due to their fixed structure, limited functionality, and complex operation. These limitations can hinder their effectiveness in handling special evacuation requirements arising from natural disasters such as climbing walls, crossing obstacles, or responding to earthquakes or mudslides. Such equipment may not provide sufficient flexibility in emergency response, leading to delays or even making rescue operations impossible.

[0003] Existing mobile rescue ladders have relatively simple deformation and extension mechanisms. Many extendable ladders require multiple extensions to complete a single task of scaling a wall or crossing an obstacle. Furthermore, because they are straight ladders, they cannot meet the needs of some special rescue scenarios, such as multiple buildings collapsing due to fire or earthquakes, resulting in broken pathways and flames at the cracks. Ordinary rescue ladders, being straight, cannot avoid being burned by flames below, failing to create an effective and safe rescue passage. Similarly, in scenarios requiring elevated levels to avoid danger and establish rescue passages, the installation of ordinary straight ladders also poses safety hazards. Therefore, developing a rescue ladder with dual-function (flexible and straight), a reasonable structure, strong adaptability, and stable reliability has become an important technological requirement for improving disaster emergency response capabilities and coping with various complex disaster scenarios.

[0004] Based on the above, this utility model proposes a multi-purpose curved and straight rescue ladder to effectively solve the above problems. Utility Model Content

[0006] The present invention adopts the following technical solution:

[0007] A multi-purpose curved and straight rescue ladder includes a U-shaped unit and a fixed base. Multiple U-shaped units are laterally rotatably connected to form a strip structure. The two ends of the strip structure are rotatably connected to the fixed base, which is used to connect to the ground or object to be fixed. The strip structure can be extended into a flat shape or compressed into an arch shape.

[0008] Furthermore, the square-shaped unit includes two sets of opposing H-shaped components. The H-shaped component includes a first component and a second component. Both the first component and the second component are T-shaped components. The first component has a double-ring at the end of its long side and one end of its short side. The second component has a double-headed pin at the end of its long side and one end of its short side. The double-headed pins are fixed in the double-headed pin seats. The first component and the second component are rotatably connected at the ends of their long sides to form an H-shaped component, and then connected to each other at their short sides to form a square-shaped unit.

[0010] Furthermore, the outer surfaces of the short sides of the first and second components are provided with inclined surfaces, which are formed by rotating inward from the outer end of the short side to the other end, with a rotation angle of 25°.

[0011] Furthermore, the other end of the short side of the first component is provided with a double-ended post, and the other end of the short side of the second component is provided with a double-ended ring. Each square unit is connected in sequence through the double-ended post of the short side of the first component and the double-ended ring of the short side of the second component.

[0012] Furthermore, each end of the elongated structure includes a first component and a second component, with a fixed connecting foot at the end of the first component and the second component, and a connecting protrusion in the center of the fixing seat, with the connecting foot rotatably connected to the fixing protrusion.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See attached document Figures 1-9 A multi-purpose curved and straight rescue ladder includes U-shaped units and fixed seats 9. Multiple U-shaped units are laterally rotatably connected to form a strip-shaped structure. The two ends of the strip-shaped structure are rotatably connected to the fixed seats 9, which are used to connect to the ground or objects to be fixed. The strip-shaped structure extends into a planar shape, such as... Figure 1 As shown, or compressed into an arch shape, such as Figure 2 As shown.

[0030] like Figure 3 , 4 As shown, the square-shaped unit includes two sets of opposing H-shaped components. Each H-shaped component includes a first component 1 and a second component 2, both of which are T-shaped components, as shown below. Figure 5 As shown. Figure 6 , 7 As shown, the first component 1 has double-loop rings 5 ​​at one end of its long side and one end of its short side 3.Figure 8 As shown, the end of the long side of the second component 2 and one end of the short side 3 are both provided with double-headed insert seats 7. The double-headed inserts 6 are fixed in the double-headed insert seats 7. The first component 1 and the second component 2 are rotatably connected at the ends of the long sides to form an H-shaped assembly, and then connected to each other through the short sides 3 to form a U-shaped unit.

[0031] The other end of the short side 3 of the first component 1 is provided with a double-ended post 6, and the other end of the short side 3 of the second component 2 is provided with a double-ended ring 5. Each square unit is connected in sequence through the double-ended post 6 of the short side 3 of the first component 1 and the double-ended ring 5 of the short side 3 of the second component 2.

[0032] The hinged connection is formed by the double insert rings 5 ​​and the double-headed inserts 6, and each connection has a gap and a certain degree of mobility, so that the square unit can be flexibly extended and retracted, and can be rotated and squeezed into an arch shape.

[0033] The outer surfaces of the short sides 3 of the first component 1 and the second component 2 are provided with inclined surfaces 4. The inclined surfaces 4 are formed by rotating inward from the outer end of the short side 3 to the other end, with a rotation angle of 25°. By setting the inclined surfaces 4, the elongated structure, combined with the U-shaped telescopic structure, can be squeezed into an arch shape, making it easy to step on.

[0034] The long sides of the first component 1 and the second component 2 are each located at one of the three equal division points on the outer side of the short side 3, forming a square shape as shown in the figure.

[0035] The long strip structure includes a first component 1 and a second component 2 at both ends. The ends of the first component 1 and the second component 2 are fixedly connected to the feet 8. The center of the fixed base 9 is provided with a connecting protrusion 10, and the connecting feet 8 are rotatably connected to the fixed protrusion.

[0036] The front end of connecting foot 8 is claw-shaped, which makes the connection more secure. The top of connecting protrusion 10 is arc-shaped, and the arc end rotates more smoothly. The front end of the claw-shaped part is equipped with a pivot, and the connecting protrusion 10 is equipped with a pivot hole. The pivot and the pivot hole are inserted into each other for connection. The positions of the pivot and the pivot hole can be interchanged.

[0037] The mounting base 9 is T-shaped to make the connection more stable, but it can also be cross-shaped, straight, etc.

[0038] The T-shaped mounting base 9 has screw holes 11 and hanging rings 12 on three sides. The screw holes 11 are used to fix the base to the ground or other places with bolts, and the hanging holes can be used to connect the base to trees, building steel bars, columns, etc. with ropes.

[0039] The inner and outer sides of the long sides of the first component 1 and the second component 2 are provided with anti-slip ridges, making it less likely to slip during the stepping process.
