For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0037] Please refer to the attached Figure 1 To the attached Figure 8 The utility model describes a foldable escape vehicle.

[0038] Figure 1 This is a schematic diagram of the front and side structure of the foldable escape vehicle of this embodiment; Figure 2 This is a schematic diagram of the bottom structure of the foldable escape vehicle of this embodiment.

[0039] This embodiment provides a foldable escape vehicle. Figure 1 and Figure 2 As shown, the foldable escape vehicle includes a first base 11 and a second base 12. The first base 11 and the second base 12 can rotate and fold relative to each other. A first clamping member 21 is provided on the first base 11, and a second clamping member 22 is provided on the second base 12. The first clamping member 21 and the second clamping member 22 can be clamped with each other to fix the folded first base 11 and the second base 12. A moving mechanism 3 is provided on the bottom side of the first base 11 and / or the second base 12. The moving mechanism 3 is used to move the first base 11 and the second base 12. The foldable escape cart is arranged by rotating the first base 11 and the second base 12 relative to each other, so that when the two bases contact each other to achieve folding, the first clamping member 21 or the second clamping member 22 can rotate with the base to lock the folded cart. Compared with traditional devices, the device reduces the overall space occupied by the device by rotating the base, improves space utilization, and thus adapts to small-sized pipes. In other words, the device avoids the problem that the entire device cannot be placed in the storage place due to the small space, and there is no place to store the device, which may cause damage to the device.

[0040] Figure 3 For this embodiment Figure 1 A partial enlarged schematic diagram of point B in the middle.

[0041] Further, if Figure 2 and Figure 3 As shown, the ends of the first clamping member and the second clamping member are both provided with a clamping portion, and a fixing groove is provided on the first base. The first clamping member can slide in the fixing groove so that the two clamping portions are clamped and fixed to each other, which is used to fix the folded first base and the second base.

[0042] Specifically, if Figure 2 and Figure 3 As shown, the clamping parts on the first clamping member and the second clamping member are both inclined surfaces.

[0043] In this embodiment, Figure 1 and Figure 2 As shown, two groups of first clamping members 21 and second clamping members 22 are provided, both of which are fixedly provided on the side of the base and evenly distributed on the left and right sides of the base.

[0044] In some embodiments, as Figure 3 As shown, the first clamping member 21 is arranged on the side of the first base 11, and a fixing groove 24 is provided at the corresponding position of the side of the first base 11, and a slider is provided at the end of the first clamping member 21 away from the inclined surface 23, wherein the slider is slidably installed in the fixing groove 24 to provide guidance for the first clamping member 21.

[0045] Figure 4 This is a schematic diagram of the structure of the foldable escape vehicle of this embodiment after partial disassembly; Figure 5 For this embodiment Figure 4 A partial enlarged schematic diagram of point D.

[0046] Further, if Figure 4 and Figure 5 As shown, the foldable escape vehicle further includes a rotating mechanism 4 , wherein there are one, two or even more rotating mechanisms 4 , which are all spaced apart at the rotating position of the first base 11 and the second base 12 .

[0047] Specifically, the rotating mechanism 4 includes a rotating shaft, wherein a torsion spring is provided on the outer sleeve of the rotating shaft, and the torsion springs are respectively abutted against the first rotating member 41 and the second rotating member 42, for separating the first rotating member 41 and the second rotating member 42 from each other. In this example, the first rotating member 41 is fixed on the first base 11, and the second rotating member 42 is fixed on the second base 12.

[0048] Optionally, two second rotating members 42 are provided, which are located at both ends of the rotating shaft, and the first rotating member 41 is located in the middle of the rotating shaft. The two ends of the torsion spring are respectively abutted against the first rotating member 41 and the second rotating member 42. The torsion spring provides continuous elastic force to the first rotating member 41 and the second rotating member 42, thereby ensuring that the folding trolley can be more stable and firm after unfolding, and avoiding folding and rebounding when the trolley slides relative to the small-diameter pipe due to the arc-shaped curved surface of the pipe, thereby further improving the adaptability of the trolley.

[0049] When the staff needs to store the device, they first rotate the second base 12 around the connection between the first rotating member 41 and the second rotating member 42. At this time, the second clamping member 22 located on the second base 12 rotates together with the second base 12 and approaches the first clamping member 21. When the first base 11 and the second base 12 contact each other, the second clamping member 22 can abut against the surface of the fixing groove 24. By sliding the slider, the first clamping member 21 and the second clamping member 22 are plugged into and matched with each other, that is, the inclined surfaces 23 of the first clamping member 21 and the second clamping member 22 are locked to each other. At this time, the first clamping member 21 and the second clamping member 22 will be locked due to the restoring force of the first rotating member 41 and the second rotating member 42. When the device needs to be used, the slider is first toggled until the inclined surfaces 23 of the first clamping member 21 and the second clamping member 22 are disengaged from each other. Then, the second base 12 is rotated around the connection between the first rotating member 41 and the second rotating member 42 until the device is fully unfolded.

[0050] Furthermore, the foldable escape vehicle further includes a fixing mechanism 5 , each fixing mechanism 5 is correspondingly provided with a moving mechanism 3 , and the fixing mechanism 5 is used to detachably fix the moving mechanism 3 on the first base 11 and / or the second base 12 .

[0051] Figure 6 For this embodiment Figure 4 A partial enlarged schematic diagram of point C.

[0052] Further, if Figure 4 and Figure 6 A first mounting hole 100 is provided on both the first base 11 and the second base 12 , and a fixing mechanism 5 is provided in the first mounting hole 100 . The fixing mechanism 5 includes a fixing rod 51 . The fixing rod 51 can extend from the first mounting hole 100 and is detachably connected to the moving mechanism 3 .

[0053] The device realizes a detachable connection to the mobile mechanism 3 through the fixing mechanism 5, which facilitates the replacement of the mobile mechanism 3, improves the service life of the entire device, avoids the need to replace the entire trolley due to damage to a certain mobile mechanism 3, thereby improving the utilization efficiency of the trolley and further reducing the use cost of the trolley.

[0054] Furthermore, if Figure 6 As shown, the fixing mechanism 5 further includes a reset member 52 , one end of which abuts against the fixing rod 51 , and the other end abuts against the inner wall of the first mounting hole 100 , for making the extended end of the fixing rod 51 close to the moving mechanism 3 .

[0055] Specifically, a pulling handle 54 is provided at the end of the fixing rod 51 and is located in the first mounting hole 100. A stopper 53 is provided on the fixing rod 51, and the reset member 52 can abut against the stopper 53. By pulling the handle 54 backward, the fixing rod 51 is moved, so that the end of the fixing rod 51 moves out of the moving mechanism 3, thereby separating the fixing rod 51 from the moving mechanism 3. At this time, the staff can install a new moving mechanism 3 on the fixing rod 51, thereby completing the replacement of the moving mechanism 3.

[0056] Furthermore, a second mounting hole 200 is provided on the first base 11 and the second base 12. The second mounting hole 200 is connected to the first mounting hole 100. The mounting end 31 of the movable mechanism 3 can be inserted into the second mounting hole 200 and detachably connected to the protruding end of the fixing rod 51. In this embodiment, the movable mechanism 3 includes universal wheels 32, which can move in multiple directions and have high maneuverability. Moreover, since the inner surface of the pipe is a curved surface, the universal wheels 32 can move on irregular and uneven surfaces, facilitating other operations by the operator.

[0057] Specifically, before using the device, the staff found that one of the universal wheels 32 was damaged. At this time, the universal wheel 32 needs to be replaced. By pulling the handle 54 backward, when the handle 54 is pulled backward, the fixing rod 51 will be driven to move backward. When the fixing rod 51 moves backward, the stop piece 53 in the middle of the fixing rod 51 will be driven to move backward. At this time, the reset member 52 will be squeezed by the stop piece 53 and the inner wall of the first mounting hole 100 and compressed. Afterwards, as the end of the fixing rod 51 moves out of the interior of the moving mechanism 3, the staff replaces the moving mechanism 3. When the replacement is completed, by loosening the handle 54, the reset member 52 will drive the fixing rod 51 and the middle stop piece 53 back to their original position due to elasticity, so that the end of the fixing rod 51 enters the interior of the moving mechanism 3.

[0058] Optionally, the mounting end 31 of the moving mechanism 3 is provided with a through hole to facilitate plug-in engagement with the fixing rod 51 .

[0059] Figure 7 For this embodiment Figure 1 A partial enlarged schematic diagram of point B; Figure 8 For this embodiment Figure 2 A partial enlarged schematic diagram of point E.

[0060] Furthermore, if Figure 7and Figure 8 As shown, a locking mechanism 6 is provided at the side end of the first base 11, and the locking mechanism 6 is used to lock and fix the unfolded first base 11 and the second base 12. The locking mechanism 6 is used to fix the unfolded device to avoid the device from being unable to be fixed during use, so that the entire device cannot work.

[0061] Furthermore, the locking mechanism 6 includes a fixing base 61 disposed at a side end of the first base 11, and a first locking member 62 that can slide relative to the fixing base 61. A hook 621 is disposed at one end of the first locking member 62 near the second base 12. The hook 621 can connect with and lock with a second locking member 64 disposed on the second base 12. The above structure can better secure the device after deployment and improve the stability of the device after deployment.

[0062] Furthermore, the locking mechanism 6 also includes an elastic member 63, which is sleeved on the outside of the first locking member 62. The end of the first locking member 62 that is not provided with a hook 621 is provided with a stop portion 622. One end of the elastic member 63 abuts against the stop portion 622, and the other end abuts against the fixed seat 61, which is used to keep the first locking member 62 away from the second locking member 64.

[0063] Optionally, the elastic member 63 and the first locking member are both disposed in the fixing seat 61 , thereby protecting the elastic member 63 and the first locking member 62 .

[0064] Furthermore, a mounting rod 65 is provided inside the fixing seat 61 . One end of the mounting rod 65 is connected to the stopper 622 , and the other end is connected to the inner wall of the fixing seat 61 . The elastic member 63 is sleeved on the mounting rod 65 .

[0065] Optionally, two sets of the mounting rods 65 and the elastic members 63 are provided.

[0066] Furthermore, a corner is provided in the middle of the first base 11 and the second base 12. It should be noted that the corner is an obtuse angle. Since the small-diameter circular tube has an arc-shaped structure, the corner-shaped first base 11 and second base 12 can easily adapt to the internal circular tube structure. In other embodiments, the first base 11 and second base 12 can also be arc-shaped, so as to better wrap the person and lower the center of gravity when the person is fixed to the base.

[0067] Furthermore, if Figure 1 and Figure 2As shown, the foldable escape vehicle also includes a rope winding mechanism 7, which is fixedly mounted on one side of the first base 11. The rope winding mechanism 7 includes fixed columns 71 fixedly mounted on both sides of the first base 11. Rope winding columns 72 are rotatably mounted within the fixed columns 71, and a rope 73 is movably sleeved above the rope winding columns 72. The rope winding mechanism 7 is used to securely wind the rope 73 after the device is no longer in use, preventing the rope 73 from being damaged by being left lying around due to the vehicle being unsecured.

[0068] When emergency escape and rescue is required or when there are injured people, the injured people can be placed on the base and the rope 73 can be removed from the rope column 72. After contacting the personnel outside the tunnel through the handheld terminal, the outside personnel can pull the rope 73 or use the winch to pull the trolley out quickly. At this time, the trolley is pulled to the exit due to the traction force, completing the pipeline rescue. When there are no injured people inside, the trapped people can lie on the trolley and pull the rope 73 to drive it, so that they can quickly save themselves. Similarly, the trapped people can get the pulling effect through the rope 73 instead of using the trolley. This avoids the problem that the inside of the escape pipe is relatively smooth, the personnel have no force point, it is inconvenient to move, and it is easy to get injured when encountering the corners of the pipe, ensuring the efficiency and safety of personnel's quick self-rescue. If it is necessary to face the risk of pipeline processing, the rope 73 can be removed from the rope column 72 in advance, and the rope 73 is pulled by the outside personnel. When danger occurs, it can effectively reduce the rescue time and improve the rescue efficiency.

[0069] Furthermore, if Figure 1 and Figure 2 As shown, the foldable escape vehicle also includes a guardrail 8 fixedly mounted on one side of the second base 12. The guardrail 8 extends above the second base 12 and is located directly in front of the device. When a person inside the pipe is above the device, they can support themselves with the guardrail 8 to ensure stability and avoid injury.
