[0027] See also Figure 1-4 ,

[0028] Embodiment 1: A power-assisted escape pipe rescue stretcher includes a first support rod 1, a second support rod 2 is arranged on the side of the first support rod 1, the first support rod 1 and the second support rod 2 are connected by a connecting cloth 3, both ends of the first support rod 1 and the second support rod 2 are provided with handles 4, the side of the connecting cloth 3 is provided with a strength reinforcement component 5, two auxiliary power-assisting components 6 are symmetrically arranged on both sides of the strength reinforcement component 5, and a pulling component 7 is provided on the side of the auxiliary power-assisting component 6.

[0029] The strength reinforcement component 5 includes a middle connecting tube 501 which is respectively sleeved on the middle part of the first support rod 1 and the second support rod 2. Two bottom reinforcing plates 502 are symmetrically arranged on the sides of the middle connecting tube 501. Both ends of the bottom reinforcing plates 502 are inserted with fixing screws 503, and the ends of the fixing screws 503 are threadedly inserted into the first support rod 1 and the second support rod 2.

[0030] The auxiliary power-assisting assembly 6 includes a supporting connecting rod 601 arranged on the bottom side of the first support rod 1 and the second support rod 2, and the top of the first support rod 1 and the second support rod 2 are respectively provided with a fixed bonding plate 602, and a fastening bolt 603 is inserted into the fixed bonding plate 602, and the bottom end of the fastening bolt 603 passes through the first support rod 1 and the second support rod 2, and both ends of the supporting connecting rod 601 are provided with a fixing socket 604, and two wheel mounting frames 606 are symmetrically provided on the bottom side of both ends of the supporting connecting rod 601, and the bottom end of the fastening bolt 603 passes through the fixing socket 604 and the top of the wheel mounting frame 606 in sequence, and the bottom end of the fastening bolt 603 is sleeved with a fastening nut 605, and a bottom wheel 607 is provided at the bottom of the wheel mounting frame 606, and the bottom wheel 607 is rotatably connected to the wheel mounting frame 606 by a rotating pin 608.

[0031] The pulling assembly 7 includes two end connecting tubes 701 respectively sleeved on the ends of the first support rod 1 and the second support rod 2. The two end connecting tubes 701 are connected by a connecting cross plate 702. A central through hole 703 is opened in the middle of the connecting cross plate 702. Two rope connecting rods 704 are symmetrically arranged on the sides of the central through hole 703. The rope connecting rods 704 are both sleeved with fixing nuts 705.

[0032] Embodiment 2: The difference between this embodiment and embodiment 1 is that the outer side surface of the handle 4 is provided with anti-slip grooves.

[0033] This makes it more stable for rescuers when lifting the device.

[0034] Embodiment 3: The difference between this embodiment and embodiment 1 is that the bottom side surface of the fixed bonding plate 602 is in an arc shape that is bonded to the second support rod 2 and the first support rod 1 .

[0035] This allows the fixed laminating plate 602 to be better engaged with the upper surfaces of the first support rod 1 and the second support rod 2 .

[0036] Embodiment 4: The difference between this embodiment and embodiment 1 is that the surface of the rope connecting rod 704 is provided with an external thread that matches the fixing nut 705.

[0037] This makes the drawstring tied to the rope connecting rod 704 more stable under the resistance of the fixing nut 705 .

[0038] In this embodiment, the currently used escape pipe rescue stretchers often ignore a problem that the trapped person may not be able to crawl through the escape pipe on his own when injured, so the trapped person cannot evacuate the dangerous area in time, causing secondary injuries.

[0039] In summary, in a specific implementation, a strength reinforcement component 5 is provided between the first support rod 1 and the second support rod 2, wherein the two bottom reinforcement plates 502 in the strength reinforcement component 5 can further strengthen the connection between the middle parts of the first support rod 1 and the second support rod 2, and an upper middle connecting tube 501 is sleeved on the middle parts of the first support rod 1 and the second support rod 2, thereby improving the middle support strength of the stretcher.

[0040] The auxiliary power-assisting components 6 are symmetrically arranged at both ends of the first support rod 1 and the second support rod 2, wherein the support connecting rod 601 in the auxiliary power-assisting component 6 is inserted into the fastening bolt 603 on the fixed bonding plate 602, and the bottom end of the fastening bolt 603 passes through the fixed socket 604 and the top of the wheel mounting frame 606, and the support connecting rod 601 and the wheel mounting frame 606 are fixedly connected to the first support rod 1 and the second support rod 2 by the fastening nut 605, and the bottom end of the wheel mounting frame 606 is rotatably fixed with the bottom wheel 607 by the rotating pin 608, thereby making it more convenient for the user to pull the stretcher, so that the contact between the bottom wheel 607 and the pipe wall is a rolling movement, which greatly saves the user's pulling force on the stretcher.

[0041] When the user needs to pull the person lying flat on the stretcher out of the escape pipe, the user first passes the end of the pulling rope through the middle through-hole 703, so that the pulling rope is tied to both sides of the first support rod 1 and the second support rod 2, and then passes the pulling rope through the middle through-hole 703 and ties it to the rope connecting rod 704. By twisting the fixing nut 705, the pulling rope tied to the rope connecting rod 704 can be fixed by resistance, thereby making the pulling of the rescue personnel safer and more secure, and facilitating the rescue.
