[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this utility model provides a technical solution: a car parking guidance device for an escalator with a chord, including a car body 1, an escalator body 2 rotatably connected between the inner walls of the car body 1, a connecting corridor 3 fixedly connected to one end of the escalator body 2, a connecting plate 4 fixedly connected to one end of the car body 1, a parking guidance mechanism 5 provided on the outer side of the connecting corridor 3, and the parking guidance mechanism 5 is used for guiding the car body 1.
[0030] The parking guidance mechanism 5 includes an arched plate 501, with a pair of fixed plates 502 fixedly connected to the inner top of the arched plate 501, and a vision camera 503 fixedly connected between the opposite sides of the pair of fixed plates 502. A double-sided sign 504 is fixedly connected between the bottom ends of the pair of fixed plates 502. Multiple laser radars 505 are fixedly connected to both the connecting corridor 3 and the outer wall of the vehicle body 1. Multiple evenly distributed distance warning lights 506 are fixedly connected to both sides of the connecting corridor 3.
[0031] According to the overall structure of the device, when the vehicle body 1 drives the escalator body 2 and the connecting corridor 3 to dock with the bottom of the aircraft door, multiple lidar sensors 505 are distributed around the vehicle body 1. They can cover a wider field of view from different angles and provide more comprehensive environmental perception, so that the vehicle body 1 can drive stably along the planned route. When approaching the aircraft, the system can accurately measure the distance between the vehicle body 1, the escalator body 2, the connecting corridor 3 and the aircraft. After reaching the deceleration distance set by the distance warning light 506, the distance warning light 506 will illuminate to issue an alarm and remind the driver. The system decelerates the vehicle, which is more accurate than human distance perception and less prone to error. It can slowly move the vehicle body 1, escalator body 2, and connecting corridor 3 towards the aircraft, reducing the risk of impact on the aircraft due to excessive speed and improving safety. During the docking process between the connecting corridor 3 and the bottom of the aircraft door, the visual camera 503 captures docking image information in real time to facilitate precise operation by the driver. After docking, the aircraft door is opened after safety checks by the staff. Following the instructions of the double-sided sign 504, passengers can board or disembark along the escalator body 2 and connecting corridor 3.
[0032] like Figure 1 and Figure 2 As shown, a rubber block 6 is fixedly connected to the end of the connecting corridor 3 away from the escalator body 2, and the rubber block 6 is semi-cylindrical in shape.
[0033] With the installation of rubber block 6, when the connecting corridor 3 comes into contact with the bottom of the aircraft door, the rubber block 6 can replace the contact end to contact the bottom of the aircraft door, reducing the impact force generated when in contact with the aircraft fuselage and protecting the paint on the aircraft surface from scratches and wear.
[0034] like Figure 1 , Figure 2 , Figure 3 Figure 4 As shown, two pairs of first vertical plates are fixedly connected to the inner bottom of the car body 1, and a first telescopic cylinder 7 is rotatably connected between the pair of first vertical plates. A U-shaped plate 8 is fixedly connected to the output end of the first telescopic cylinder 7. A pair of connecting blocks 9 are fixedly connected to the lower surface of the escalator body 2. The U-shaped plate 8 is sleeved on the outside of the connecting block 9, and the inner wall of the U-shaped plate 8 is rotatably connected to the outer wall of the connecting block 9.
[0035] By extending the first telescopic cylinder 7, the U-shaped plate 8 can be pushed to move to the upper right, causing it to rotate the escalator body 2 along the upper right via the connecting block 9, thereby adjusting the height of the escalator body 2 and the connecting corridor 3 to facilitate subsequent docking.
[0036] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, a pair of lifting auxiliary mechanisms 10 are provided at the top of the connecting plate 4. Each lifting auxiliary mechanism 10 includes a rectangular straight frame 1001. A second vertical plate is rotatably connected to both sides of the rectangular straight frame 1001, and the bottom end of the second vertical plate is fixedly connected to the top of the connecting plate 4. A rectangular rod 1002 is slidably connected inside the rectangular straight frame 1001. A third vertical plate is rotatably connected to both sides of the rectangular rod 1002, and the top end of the third vertical plate is fixedly connected to the bottom end of the connecting corridor 3. Side connecting plates 1003 are fixedly connected to both sides of the rectangular straight frame 1001, and a second telescopic cylinder 1004 is fixedly connected to one end of each side connecting plate 1003. A round hole is drilled at one end of the side plate 1003, and the second telescopic cylinder 1004 passes through the round hole and is fixedly connected to the limiting block 1005. A pair of rectangular through holes are drilled on both sides of the rectangular straight frame 1001. Multiple evenly distributed limiting grooves 1006 are drilled on both sides of the rectangular rod 1002, and one end of the limiting block 1005 passes through the rectangular through hole and extends into the limiting groove 1006. A pair of sliders 10021 are fixedly connected to the outer wall of the rectangular rod 1002. A pair of sliding grooves 10022 are drilled on the inner wall of the rectangular straight frame 1001, and the sliders 10021 are located in the sliding grooves 10022 and are slidably connected to them.
[0037] With the lifting auxiliary mechanism 10, during the lifting and adjustment of the connecting corridor 3, a pair of rectangular rods 1002 move synchronously along the inside of the rectangular straight frame 1001 with the sliding assistance of the slider 10021 and the slide groove 10022. After the movement is completed, a pair of second telescopic cylinders 1004 drive a pair of limit blocks 1005 to move towards each other and insert into the corresponding pair of limit grooves 1006 to limit and fix them, providing stable support for the connecting corridor 3 and reinforcing the support stability of the escalator body 2 and the connecting corridor 3, so as to provide stable support for subsequent personnel to step on.
[0038] like Figure 1 and Figure 2 As shown, the escalator body 2 is fixedly connected to a step 11 at the end away from the connecting corridor 3.
[0039] The step 11 provides a more stable transition zone for people with mobility impairments, making it easier for them to get on and off the escalator body 2.
[0040] like Figure 1 and Figure 2 As shown, a pair of lifting cylinders 12 are embedded and connected to the top of the connecting plate 4 and the end of the car body 1 away from the connecting plate 4, and the output end of the lifting cylinder 12 is fixedly connected to the lower pressure plate 13. The bottom end of the lower pressure plate 13 is flush with the bottom end of the car body 1.
[0041] Two pairs of lifting cylinders 12 drive two pairs of lower pressure plates 13 to contact the ground, assisting in fixing the car body 1, which can improve the stability of the car body 1 and ensure stability when passengers board and disembark.
[0042] Working principle: As the vehicle body 1 moves, driving the escalator body 2 and connecting corridor 3 towards the aircraft, multiple lidar sensors 505 comprehensively perceive the environment from different angles, ensuring the vehicle body 1 travels stably along the planned route. During the approach to the aircraft, the lidar sensors 505 measure the distance between the vehicle body 1, escalator body 2, connecting corridor 3, and the aircraft. Once the distance warning light 506 reaches the deceleration distance set by the distance warning light 506, the distance warning light 506 illuminates to alert the driver to slow down. Simultaneously, the first telescopic cylinder 7 extends, pushing the U-shaped plate 8 to move upwards and to the right. This causes the connecting block 9 to rotate the escalator body 2 upwards and to the right, adjusting the height of the escalator body 2 and connecting corridor 3 to correspond with the bottom of the aircraft door. During this adjustment process, a pair of rectangular rods... With the sliding assistance of slider 10021 and slide 10022, 1002 moves synchronously with the connecting corridor 3. After adjustment, a pair of second telescopic cylinders 1004 drive a pair of limit blocks 1005 to move towards each other and insert into the corresponding pair of limit grooves 1006 for limiting and fixing, providing stable support for the connecting corridor 3. Then, under the real-time monitoring of the vision camera 503, the car body 1 is driven to move slowly, so that it drives the connecting corridor 3 and rubber block 6 to contact the bottom of the aircraft door. Immediately afterwards, two pairs of lifting cylinders 12 drive two pairs of lower pressure plates 13 to move downward until they contact the ground, assisting in fixing the car body 1. After the aircraft door is opened, personnel follow the instructions of the double-sided sign 504 to board or disembark along the escalator body 2 and connecting corridor 3.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
