Description

Technical Field

[0001] This utility model relates to the field of boarding stairs technology, specifically to a folding boarding stairs for low-altitude sightseeing aircraft. Background Technology

[0002] Low-altitude sightseeing aircraft refer to aircraft that fly at low altitudes (usually within the range of 100-1000 meters above the ground or water surface, which can be extended to 4000 meters depending on the characteristics of different regions and actual needs) for sightseeing, leisure, entertainment and other tourism activities. When using low-altitude sightseeing aircraft, boarding stairs are required to facilitate the boarding and disembarking of tourists. In actual use, they have advantages such as structural stability and good performance.

[0003] The prior art discloses a folding aircraft boarding ladder with application number CN202220943771.4. Although the above-mentioned utility model can realize the folding of the boarding ladder, the folding length is limited, and the boarding ladder has no protective structure after folding. When it is moved and collided with by external objects, it is easy to damage the folded boarding ladder, reducing the practicality of this utility model. At the same time, there is no connecting structure at the bottom of the boarding ladder, which can easily cause the boarding ladder to sway when tourists climb the boarding ladder, posing a hidden danger to the stable use of this utility model.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a folding boarding ladder for low-altitude sightseeing aircraft. It features a retractable ladder structure that prevents external objects from touching the retractable ladder structure and a connecting structure that enables connection at the bottom of the ladder structure, thereby solving the problems mentioned in the background technology.

[0006] To achieve the advantages of a retractable and foldable ladder structure, preventing external objects from touching the retractable and foldable ladder structure, and having a connecting structure to achieve bottom connection of the ladder structure, the specific technical solution adopted by this utility model is as follows:

[0007] A folding boarding ladder for low-altitude sightseeing aircraft includes a housing. Inside the housing, a winding roller is mounted via bearings. Two sets of pull ropes are mounted on the side wall of the winding roller. The lower ends of the two sets of pull ropes are connected to connecting lugs. A base box is mounted at the lower ends of the two sets of connecting lugs. Multiple sets of support ropes are installed between the two sets of pull ropes. An electrical control box is mounted on the upper part of the housing. The electrical control box contains a first control panel, a synchronous controller, and a first battery. A self-locking forward and reverse motor is mounted on one side of the housing. The output end of the self-locking forward and reverse motor is connected to the winding roller via a coupling. Two sets of support covers are mounted on both sides of the housing. A first electric telescopic rod is fixedly inserted through the upper part of each of the four sets of support covers. A first self-locking universal wheel is mounted on the telescopic end of each of the four sets of first electric telescopic rods. Mounting plates are mounted on the side walls of each of the four sets of support covers.

[0008] Furthermore, a second electric telescopic rod is fixedly inserted through both the top and bottom surfaces of the base box. Two sets of T-shaped rods slide through both the top and bottom surfaces of the base box. A movable plate is installed at the telescopic end of one set of the second electric telescopic rods on the same side and at one end of the two sets of T-shaped rods on the same side. A frosted plate is installed on the far side of both sets of movable plates. A second battery is installed on the inner wall of the base box, and a second control panel is installed on the side wall of the base box.

[0009] Furthermore, the second control panel is electrically connected to the second battery and the two sets of the second electric telescopic poles via wires.

[0010] Furthermore, the lower part of the base box is equipped with four sets of second self-locking casters.

[0011] Furthermore, a door is installed on the end face of the bottom box via a hinge.

[0012] Furthermore, the first control panel is electrically connected to the first battery, the self-locking forward and reverse motor, and the synchronization controller via wires. The synchronization controller is electrically connected to the four sets of the first electric telescopic rods via wires.

[0013] Furthermore, the sidewalls of multiple sets of support ropes are fitted with rubber sleeves.

[0014] Compared with the prior art, this utility model provides a folding boarding ladder for low-altitude sightseeing aircraft, which has the following advantages:

[0015] (1) This utility model adopts a winding roller, a pull rope, and a support rope. When actually using the folding boarding ladder of a low-altitude sightseeing aircraft, the first control panel can be used to extend the four sets of first electric telescopic rods synchronously through the synchronous controller. When the four sets of first self-locking universal wheels support the box, the box can be moved with the help of the four sets of first self-locking universal wheels. When the box is moved to the installation position, the first control panel can be used to shorten the four sets of first electric telescopic rods synchronously through the synchronous controller. When the four sets of first self-locking universal wheels enter the four sets of support covers respectively, the four sets of support covers will contact the bottom surface of the cabin. Then, bolts are used to connect the four sets of mounting holes to the bottom surface of the cabin. The cabin interior floor is connected via threaded holes. The first control panel then activates a self-locking forward / reverse motor. The output of this motor drives a take-up roller to rotate, unwinding two sets of pull ropes. The control panel also allows the motor to reverse the rotation, winding up the two sets of pull ropes. Tourists can step on multiple support ropes to board and disembark. The take-up roller, pull ropes, and support ropes ensure the folding ladder structure can be retracted without foreign objects touching it, improving the practicality of the folding boarding ladder for low-altitude sightseeing aircraft.

[0016] (2) This utility model adopts a base box. According to the above operation, after the two sets of pull ropes are unwound, the base box can be moved by four sets of second self-locking universal wheels. When the base box is moved to the bottom of the baggage tractor, the two sets of second electric telescopic rods can be extended by using the second control panel. When the two sets of frosted plates contact the lower part of the baggage tractor and the ground respectively, the friction force can ensure the stable fixation of the base box. At this time, the two sets of pull ropes are taut, and tourists can climb stably by using multiple sets of support ropes. The four sets of T-shaped rods can ensure the stability of the movement of the two sets of moving plates. The base box has a connecting structure, which can realize the bottom connection of the ladder structure, and provide a guarantee for the stable use of the folding boarding ladder of the low-altitude sightseeing aircraft.

[0032] In one embodiment, the sidewalls of multiple sets of support ropes 4 are all fitted with rubber sleeves 5.

[0033] Working principle:

[0034] In actual use of the folding boarding ladder for low-altitude sightseeing aircraft, the first control panel can be used to synchronously extend four sets of first electric telescopic rods 11 via a synchronous controller. When the four sets of first self-locking casters 12 support the housing 1, the housing 1 can be moved using the four sets of first self-locking casters 12. When the housing 1 is moved to the installation position, the first control panel can be used again to synchronously shorten the four sets of first electric telescopic rods 11 via a synchronous controller. When the four sets of first self-locking casters 12 enter the four sets of support covers 10 respectively, the four sets of support covers 10 will contact the bottom surface of the cabin interior. Then, bolts are used to connect the four sets of mounting plates 17 to the threaded holes on the bottom surface of the cabin interior. Then, the first control panel can be used to operate the self-locking forward and reverse motor 9. The output end of the self-locking forward and reverse motor 9 can drive the take-up roller 2 to rotate. The rotating take-up roller 2 can unwind two sets of pull ropes 3. The first control panel can be used to drive the output end of the self-locking forward and reverse motor 9 to rotate the take-up roller 2 in the opposite direction. The reverse rotating take-up roller 2 can wind up two sets of pull ropes 3. Rope 3 allows tourists to board and disembark by stepping on multiple sets of support ropes 4. The folding ladder structure can be wound up using the winding roller 2, pull rope 3, and support rope 4, preventing external objects from contacting the folded ladder and improving its practicality. Furthermore, after the two sets of pull ropes 3 have been unwound, the base box 7 can be moved using four sets of second self-locking casters. Once the base box 7 is under the baggage trolley, the second control panel can then be used... The two sets of second electric telescopic rods 13 are extended. When the two sets of frosted plates 16 contact the lower part of the baggage tractor and the ground respectively, the friction force can ensure the stable fixation of the bottom box 7. At this time, the two sets of pull ropes 3 are taut. Tourists can climb stably by multiple sets of support ropes 4. The four sets of T-shaped rods 14 can ensure the stability of the movement of the two sets of moving plates 15. The bottom box 7 has a connecting structure, which can realize the bottom connection of the ladder structure, thus ensuring the stable use of the folding boarding ladder for low-altitude sightseeing aircraft.
