[0002] Airline catering trucks are special vehicles for airports, which are used to prepare meals for passenger planes. When the cabin door height of the aircraft to be docked is low, the docking platform of the catering truck cannot be completed due to the influence of the catering truck's cab. In the existing technology, by converting the cab into a semi-cab form and reducing the width of the docking platform at the same time, the docking platform is located on one side of the cab. In this way, the height of the docking platform is not affected by the height of the cab, and the service height of the airline catering truck docking with low-cab aircraft can be achieved.

[0072] See also Figure 1 to Figure 2The aviation catering vehicle 10 of the present application includes a reception platform 12 and a driver's cab 11. The reception platform 12 includes a first platform 100, a second platform 200 and a control device. The first platform 100 has a first height H1; the second platform 200 has a second height H2, and the second height H2 is greater than the first height H1. When the first height H1 is equal to the second height H2, the second platform 200 is adjacent to the first platform 100 and can be combined with the first platform 100 to form a joint platform. The control device controls the joint movement of the first platform 100 and the second platform 200. When the first height H1 is less than the second height H2, the control device controls the first platform 100 to lift, and the second height H2 of the second platform 200 remains unchanged; when the first height H1 is equal to the second height H2, the control device controls the first platform 100 and the second platform 200 to lift synchronously. The control device includes a PLC controller, a logic controller or a CPU controller, etc. The control device also includes a computing unit and other necessary unit modules required to complete the control. The controller and each unit module can adopt the controller and unit module in the prior art, which will not be repeated here.

[0073] The pick-up platform 12 of the present application is provided with a first platform 100 and a second platform 200 of different heights, and can dock with a small aircraft with a lower height, and can also dock with a large aircraft with a higher height. When docking with a small aircraft with a lower cabin door, the first platform 100 with a lower height is used to complete the docking work. When docking with a large aircraft with a higher height, the first platform 100 is lifted and then lifted together with the second platform 200 to complete the docking work. The pick-up platform 12 proposed in the present application, the first platform 100 and the second platform 200 are arranged adjacently when the heights are the same, and the first platform 100 and the second platform 200 can form a joint platform, which meets the requirements of the pick-up platform 12 for docking with large aircraft, with a large working area, easy operation, and improved catering efficiency. A control device is provided to control the joint movement of the first platform 100 and the second platform 200 to ensure the safety of the working process and the reliability of the joint platform composed of the first platform 100 and the second platform 200.

[0074] The airline food cart of this application, see Figure 1 The first platform 100 is disposed on one side of the cab 11, so that the first height H1 of the first platform 100 is relatively small, and can be used to provide meals for small airplanes with lower cabin doors. The second platform 200 is disposed on the top of the cab 11, see Figure 2 When it is necessary to provide meals for a large aircraft with a higher cabin door, the control device controls the first platform 100 and the second platform 200 to move jointly. After the first platform 100 and the second platform 200 are lifted to a corresponding height, the first platform 100 and the second platform 200 are combined into a larger joint platform to provide meals for the large aircraft with high meal preparation efficiency.

[0075] In some other cases, the airline catering vehicle of the present application can also dock with an aircraft with a higher cabin door using only the second platform 200. That is to say, the first platform 100 of the airport reception platform 12 of the present application can be used alone, the second platform 200 can be used alone, or the first platform 100 and the second platform 200 can be used together.

[0076] In this embodiment, the second platform 200 is located at the top of the driver's cab 11 and is installed on the bottom beam of the vehicle body. The first platform 100 is located on the left side of the driver's cab 11 and is connected to the vehicle body slideway through rollers. The first platform 100 can slide up and down on the vehicle body. A photoelectric switch is installed on the side of the second platform 200. When the first platform 100 rises to the same height as the second platform 200 along with the vehicle body, the photoelectric switch acts to transmit a signal to the control device, and the second platform 200 and the first platform 100 are lifted synchronously at the same time, and the second telescopic platform 202 of the second platform 200 and the first telescopic platform 102 of the first platform 100 can be extended or retracted at the same time. The second telescopic platform 202 is controlled by the second telescopic oil cylinder, and the first telescopic oil cylinder is controlled by the first telescopic oil cylinder. The second telescopic oil cylinder and the first telescopic oil cylinder are controlled by the speed regulating valve to realize the synchronous extension and retraction of the first telescopic platform 102 and the second telescopic platform 202. By adjusting the opening of the speed regulating valve, the speeds of the two oil cylinders can also be controlled separately to achieve precise speed control. The synchronous control of the two telescopic platforms effectively avoids the staff from stepping on and falling due to the different extension distances of the two telescopic platforms. In some other embodiments, the first platform 200 can be located on the right side of the driver's cab 11.

[0077] See also Figure 2 The aviation food cart of the present application further includes a lifting device, which is disposed below the first platform 100 and the second platform 200. The lifting device can lift the first platform 100 alone, the second platform 200 alone, or the first platform 100 and the second platform 200 simultaneously. The lifting device can be a hydraulic device or other lifting devices commonly used in the art. The lifting device is electrically connected to the control device, and the control device controls the lifting of the first platform 100 and the second platform 200 by controlling the lifting device.

[0078] See also Figure 3 to Figure 4 In this embodiment, the first platform 100 includes a first fixed platform 101 and a first telescopic platform 102 . The first telescopic platform 102 is disposed on a side of the first fixed platform 101 facing the aircraft and can be telescoped relative to the first fixed platform 101 .

[0079] The second platform 200 includes a second fixed platform 201 and a second telescopic platform 202 . The second telescopic platform 202 is disposed on a side of the second fixed platform 201 facing the aircraft and can be telescoped relative to the second fixed platform 201 .

[0080] See also Figure 2 When the first height H1 is equal to the second height H2, and the first platform 100 and the second platform 200 stop lifting, the control device controls the first telescopic platform 102 and the second telescopic platform 202 to be telescoped synchronously at the same time.

[0081] The airport reception platform 12 of the present application, when docking with a large aircraft, the first platform 100 and the second platform 200 form a joint platform, the control device first controls the lifting of the first platform 100, and the second height H2 of the second platform 200 remains unchanged, and when the first platform 100 is lifted to the same height as the second platform 200, the control device starts the first platform 100 and the second platform 200 to be lifted synchronously at the same time, and when the first platform 100 and the second platform 200 are lifted synchronously to the required height, the control device controls the first telescopic platform 102 of the first platform 100 and the second telescopic platform 202 of the second platform 200 to be extended synchronously at the same time, ensuring that the two telescopic platforms are safely and synchronously extended to the position of the large aircraft cabin door.

[0082] The first telescopic platform 102 and the second telescopic platform 202 are also provided with an anti-collision rubber tube, a proximity switch or an ultrasonic switch at one end facing the aircraft cabin door, so as to prevent the two telescopic platforms from colliding with the aircraft cabin door.

[0083] In this embodiment, see Figure 3 and Figure 4 The first fixed platform 101 includes a first fixed platform body 1011, a first fixed outer guardrail 1012 and a first fixed inner guardrail 1013, and the first fixed outer guardrail 1012 and the first fixed inner guardrail 1013 are respectively arranged on opposite sides of the first fixed platform body 1011.

[0084] The second fixed platform 201 includes a second fixed platform body 2011 , a second fixed outer guardrail 2012 and a second fixed inner guardrail 2013 . The second fixed outer guardrail 2012 and the second fixed inner guardrail 2013 are respectively disposed on two opposite sides of the second fixed platform body 2011 .

[0085] When the first height H1 is equal to the second height H2, the first fixed inner guardrail 1013 and the second fixed inner guardrail 2013 are adjacent to each other, and the first fixed outer guardrail 1012 and the second fixed outer guardrail 2012 are separated from each other.

[0086] When the first height H1 is equal to the second height H2, and the first platform 100 and the second platform 200 stop lifting, the control device controls the first fixed inner guardrail 1013 and the second fixed inner guardrail 2013 to rotate counterclockwise or clockwise at the same time.

[0087] When the first platform 100 and the second platform 200 stop lifting, the control device controls the adjacent first fixed inner guardrail 1013 and the second fixed inner guardrail 2013 to rotate in the same direction at the same time, so that the first fixed platform 101 and the second fixed platform 201 can be combined to form a larger fixed platform. The axis of rotation can be the guardrail axis of the first fixed inner guardrail 1013 and the second fixed inner guardrail 2013 away from the aircraft side, or it can be other axes, which can be selected according to actual conditions. Since there may be a gap between the first fixed platform 101 and the second fixed platform 201 after the adjacent guardrails rotate, a connecting plate extending toward the other side can also be provided on the first fixed platform 101 or the second fixed platform 201 to cover the gap, which is more conducive to the smooth travel of the catering vehicle and ensures that the catering vehicle remains stable during operation. The connecting plate is also retractable and can be an aluminum plate, etc. Of course, in some other embodiments, the connecting plate can also be placed by the staff.

[0088] In this embodiment, see Figure 3 and Figure 4 The first telescopic platform 102 includes a first telescopic platform body 1021, a first telescopic outer guardrail 1022 and a first telescopic inner guardrail 1023, and the first telescopic outer guardrail 1022 and the first telescopic inner guardrail 1023 are respectively arranged on opposite sides of the first telescopic platform body 1021.

[0089] The second telescopic platform 202 includes a second telescopic platform body 2021 , a second telescopic outer guardrail 2022 and a second telescopic inner guardrail 2023 . The second telescopic outer guardrail 2022 and the second telescopic inner guardrail 2023 are respectively disposed on two opposite sides of the second telescopic platform body 2021 .

[0090] The first telescopic inner guardrail 1023 is close to the second telescopic inner guardrail 2023, and the first telescopic outer guardrail 1022 is far away from the second telescopic outer guardrail 2022. When the first telescopic platform 102 is at the same height as the first telescopic platform 202, the first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 are adjacent to each other and are located in the middle of the joint platform formed by the first telescopic platform 102 and the first telescopic platform 202. The first telescopic outer guardrail 1022 and the second telescopic outer guardrail 2022 are far away from each other and are respectively located on both sides of the joint platform formed by the first telescopic platform 102 and the first telescopic platform 202.

[0091] When the first telescopic platform 102 and the second telescopic platform 202 stop telescoping, the control device controls the first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 to rotate counterclockwise or clockwise at the same time.

[0092] When the first telescopic platform 102 and the second telescopic platform 202 stop telescoping, the control device controls the adjacent first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 to rotate in the same direction at the same time, so that the first telescopic platform 102 and the second telescopic platform 202 can be combined to form a larger telescopic platform. The axis of rotation can be the guardrail axis of the first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 away from the aircraft side, or it can be other axes, which can be selected according to actual conditions. Since there may be a gap between the first telescopic platform 102 and the second telescopic platform 202 after the adjacent guardrails rotate, a connecting plate extending toward the other side can also be provided on the first telescopic platform 102 or the second telescopic platform 202 to cover the gap, which is more conducive to the smooth travel of the catering vehicle and ensures that the catering vehicle remains stable during operation. The connecting plate is also retractable. In some other embodiments, the connecting plate can also be placed by the staff. The connecting plate can be an aluminum plate or a plate of other materials.

[0093] In this embodiment, electronic locks can be set between each guardrail of the two platforms for safety control. When the height of the second platform 200 and the first platform 100 are different, the electronic locks of each guardrail of the two platforms are locked, and the guardrails cannot rotate. When the first telescopic platform 102 and the second telescopic platform 202 stop telescoping, the electronic locks of each guardrail are opened, and the adjacent guardrails of the second platform 200 and the first platform 100 can be rotated at any angle. At this time, the second platform 200 and the first platform 100 are combined into a full-width joint platform, which is helpful for workers to pass into the cabin.

[0094] In this embodiment, the receiving platform 12 also includes an actuator such as a mechanism for rotating the guardrail, a mechanism for opening the guardrail under load, etc. The actuators such as the mechanism for rotating the guardrail, the mechanism for opening the guardrail under load, etc. are all electrically connected to the control device.

[0095] See also Figure 3 and Figure 4 , wherein position W1 represents the position when the telescopic platform is not extended, and position W2 represents the position when the telescopic platform is extended. It can be seen that an anti-collision rubber tube is provided at the front end of the telescopic platform.

[0096] The pick-up platform 12 of the present application also has another embodiment, and the pick-up platform 12 of the other embodiment is Figures 1 to 4 Compared with the pick-up platform 12 of the embodiment of the present invention, the basic structure of the pick-up platform 12 has substantially the same structure. Therefore, in the following description of the pick-up platform 12 of the other embodiment, the description will not be repeated. Figures 1 to 4 In addition, Figures 1 to 4The same reference numerals are used for the same structures as those of the receiving platform 121 described in the embodiment of FIG.

The second telescopic outer guardrail 2022 and the second telescopic inner guardrail 2023 are respectively disposed on two opposite sides of the second telescopic platform body 2021 .

[0100] The first telescopic inner guardrail 1023 is close to the second telescopic inner guardrail 2023, and the first telescopic outer guardrail 1022 is far away from the second telescopic outer guardrail 2022. When the first telescopic platform 102 is at the same height as the first telescopic platform 202, the first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 are adjacent to each other and are located in the middle of the joint platform formed by the first telescopic platform 102 and the first telescopic platform 202. The first telescopic outer guardrail 1022 and the second telescopic outer guardrail 2022 are far away from each other and are respectively located on both sides of the joint platform formed by the first telescopic platform 102 and the first telescopic platform 202.

[0101] When the first height H1 is equal to the second height H2, and the first platform 100 and the second platform 200 stop lifting, the control device controls the first telescopic platform body 1021 and the second telescopic platform body 2021 to be telescoped synchronously at the same time.

[0102] When the first telescopic platform body 1021 and the second telescopic platform body 2021 stop telescoping, the control device controls the first telescopic outer guardrail 1022, the first telescopic inner guardrail 1023, the second telescopic outer guardrail 2022 and the second telescopic inner guardrail 2023 to open, and the first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 rotate counterclockwise or clockwise at the same time.

[0103] In this other embodiment, the first telescopic outer guardrail 1022 and the first telescopic inner guardrail 1023 are not telescopically moved together with the first telescopic platform body 1021, and the second telescopic outer guardrail 2022 and the second telescopic inner guardrail 2023 are not telescopically moved together with the second telescopic platform body 2021. When the first telescopic platform body 1021 and the second telescopic platform body 2021 stop telescoping, the control device controls the first telescopic outer guardrail 1022, the first telescopic inner guardrail 1023, the second telescopic outer guardrail 2022 and the second telescopic inner guardrail 2023 to open, and then controls the adjacent first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 to rotate simultaneously, so as to combine the first platform 100 and the second platform 200 into a joint platform for supplying catering to the aircraft.

[0104] The above is a detailed description of several exemplary embodiments of the pick-up platform 12 proposed in this application, see Figures 1 to 4 The present application also proposes a control method for an airport pick-up platform, wherein the airport pick-up platform is the airport pick-up platform 12 as described above, wherein the first platform 100 includes a first fixed platform 101 and a first telescopic platform 102, the first telescopic platform 102 is arranged on the side of the first fixed platform 101 facing the aircraft, and can be telescopic relative to the first fixed platform 101; the second platform 200 includes a second fixed platform 201 and a second telescopic platform 202, the second telescopic platform 202 is arranged on the side of the second fixed platform 201 facing the aircraft, and can be telescopic relative to the second fixed platform 201. The control method includes:

[0105] Control the first platform 100 to lift so that the first height H1 is equal to the second height H2;

[0106] Control the first platform 100 and the second platform 200 to be simultaneously and synchronously lifted to a height that docks with the aircraft door;

[0107] Control the first telescopic platform 102 of the first platform 100 and the second telescopic platform 202 of the second platform 200 to extend synchronously at the same time, so that the first platform 100 and the second platform 200 are in contact with the aircraft cabin door;

[0108] The first platform 100 and the second platform 200 are controlled to form a joint platform.

[0109] The control method of the airport reception platform 12 of the present application is as follows: when the airport reception platform 12 docks with a large aircraft at a relatively high height, the first platform 100 is lifted, and when the first height H1 of the first platform 100 is equal to the second height H2 of the second platform 200, the control device controls the lifting device to lift the first platform 100 and the second platform 200 simultaneously and synchronously. When lifted to a height capable of docking with the cabin door of the large aircraft, the control device controls the first telescopic platform 102 of the first platform 100 and the second telescopic platform 202 of the second platform 200 to be simultaneously and synchronously extended to contact with the cabin door of the aircraft.

[0110] During the docking process of the receiving platform 12, when the first height H1 is less than the second height H2, the control device ensures that the first platform 100 is lifted and the second platform 200 is stationary.

[0111] When the first height H1 is equal to the second height H2, the control device controls the lifting device to ensure that the first platform 100 and the second platform 200 are lifted synchronously at the same time. It is impossible that the first platform 100 is lifted first and the second platform 200 is lifted later, or the second platform 200 is lifted first and the first platform 100 is lifted later.

[0112] When the telescopic platform needs to be extended, the control device controls the first telescopic platform 102 and the second telescopic platform 202 to be extended synchronously at the same time to ensure the safety of personnel, avoid the occurrence of safety accidents, and improve the safety of meal preparation.

[0113] When the telescopic platform is telescoped into place, the control device controls the formation of the combined platform.

[0114] The pick-up platform 12 of the present application can be provided with a height detector to detect the height. The height detector can send the detected height information to the control device. After the control device receives the height information, it performs calculations and judgments, and then issues a control command to the corresponding actuator (such as a lifting device, a mechanism responsible for rotating the guardrail, etc.).

[0115] When the first platform 100 is lifted to the set height, the height detector detects the height and sends the height information to the control device. The control device can start the lifting function of the second platform 200 and control the lifting device to lift the first platform 100 and the second platform 200 simultaneously. When the height detector detects that both platforms are lifted to the required height, the control device can start the simultaneous extension of the two telescopic platforms. When the two telescopic platforms are extended to the right position, the anti-collision rubber tube or switch set at the front end of the telescopic platform can be used to send a signal to the control device. After receiving the signal, the control device controls the telescopic platform to stop extending.

[0116] In this embodiment, the first fixed platform 101 includes a first fixed inner guardrail 1013, and the second fixed platform 201 includes a second fixed inner guardrail 2013. When the first height H1 is equal to the second height H2, the first fixed inner guardrail 1013 and the second fixed inner guardrail 2013 are adjacent. The first fixed inner guardrail 1013 and the second fixed inner guardrail 2013 are controlled to rotate counterclockwise or clockwise at the same time, so that the first platform 100 and the second platform 200 form a joint platform.

[0117] When the first platform 100 and the second platform 200 stop lifting, the adjacent first fixed inner guardrails 1013 and second fixed inner guardrails 2013 are controlled to rotate in the same direction at the same time, so that the first fixed platform 101 and the second fixed platform 201 can be combined to form a larger fixed platform.

[0118] In this embodiment, the first telescopic platform 102 includes a first telescopic inner guardrail 1023, the second telescopic platform 202 includes a second telescopic inner guardrail 2023, and the first telescopic inner guardrail 1023 is close to the second telescopic inner guardrail 2023. The adjacent first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 are controlled to rotate counterclockwise or clockwise at the same time, so that the first platform 100 and the second platform 200 form a joint platform.

[0119] When the first telescopic platform 102 and the second telescopic platform 202 stop telescoping, the adjacent first telescopic inner guardrail 1023 and the second telescopic inner guardrail 2023 are controlled to rotate in the same direction at the same time, so that the first telescopic platform 102 and the second telescopic platform 202 can be combined to form a larger telescopic platform.

[0120] The present application also proposes another control method of the pick-up platform 12, which is: controlling the first telescopic platform 102 of the first platform 100 to dock with the aircraft cabin door, controlling the guardrails on both sides of the first platform 100 to open, and controlling the guardrails on both sides of the first telescopic platform 102 to open or extend. This control method is mainly for a small aircraft with a low cabin door, and is a control method for the pick-up platform 12.

[0121] In summary, the pick-up platform 12 proposed in the present application is provided with a first platform 100 and a second platform 200 of different heights. When docking a small aircraft with a lower cabin door, the first platform 100 with a lower height is used to complete the docking work. When docking a large aircraft with a higher height, the first platform 100 is lifted and then lifted together with the second platform 200 to complete the docking work. The pick-up platform 12 of the present application can dock a small aircraft with a lower height, and can also dock a large aircraft with a higher height. The first platform 100 and the second platform 200 are arranged adjacent to each other at the same height, and the first platform 100 and the second platform 200 can form a joint platform, which meets the requirements of the pick-up platform 12 for docking a large aircraft. The work area is large, the operation is simple, and the catering efficiency is improved. A control device is provided to control the joint movement of the first platform 100 and the second platform 200 to ensure the safety of the working process.

[0122] The airline catering vehicle of the present application is equipped with the above-mentioned receiving platform 12, wherein the first platform 100 is arranged at one side of the driver's cabin 11, and the second platform 200 is arranged at the top of the driver's cabin 11. The above-designed airline catering vehicle can dock with small aircrafts with a lower height, and can also dock with large aircrafts with a higher height, and when docking with large aircrafts, the working area is larger, the operation is simple, and the catering efficiency is high.
