Description

Technical Field

[0001] The invention belongs to the technical field of maintenance platforms, and in particular relates to an aircraft windshield maintenance platform. Background Art

[0002] Aircraft windshield maintenance typically involves repairing and replacing windshields, as well as inspecting and repairing the windshield mounting frame. Due to the large size of windshields, this work requires three to four maintenance personnel working simultaneously.

[0003] However, for small aircraft, due to their small size, a small maintenance platform is required, but the small maintenance platform has insufficient space. Moreover, for aircraft of different sizes, different maintenance platforms are required in each maintenance. Different maintenance platforms occupy a large space, and the distance between the aircraft and the maintenance platform needs to be adjusted to avoid the danger of maintenance personnel falling due to the large gap. Therefore, there are deficiencies in use. Summary of the Invention

[0004] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides an aircraft windshield maintenance platform.

[0005] The present application proposes an aircraft windshield maintenance platform, comprising a U-shaped support plate, a plurality of legs fixedly mounted on the bottom surface of the U-shaped support plate, a step ladder mounted on one side of the U-shaped support plate, and three sets of extension mechanisms slidably mounted on the top surface of the U-shaped support plate.

[0006] Specifically, three groups of grooves are provided on the top surface of the U-shaped support plate, each group of grooves consists of two grooves, a screw with a motor is movably installed in each groove, two nuts are provided on the screw thread, and the top of the nut in the same group of grooves is connected to a group of extension mechanisms.

[0007] Specifically, the extension mechanism includes a base plate, the top of the nut is fixedly connected to the bottom surface of the base plate, the lifting component is installed on the top surface of the base plate, the placement plate is installed on the top surface of the lifting component, and the moving component is slidably installed on the top surface of the placement plate.

[0008] Specifically, the lifting assembly includes several cylinders, the bottom ends of the fixed ends of the cylinders are installed on the top surface of the base plate, and the top ends of the movable ends of the cylinders are fixedly connected to the bottom surface of the placement plate.

[0009] Specifically, the moving assembly includes two groups of support plate groups, which are respectively located on both sides of the placement plate. Each group of support plate groups consists of two support plates. The two support plates in each group of support plate groups are respectively located at the front and rear ends of the placement plate. The bottom end of the support plate is fixedly connected to the top surface of the placement plate. A control component is installed between the two support plates in each group of support plate groups. A support plate is arranged above the two groups of support plate groups, and the bottom end of the support plate is connected to the two groups of control components.

[0010] Specifically, the control component includes a threaded rod with a motor, the motor of the threaded rod is fixedly installed on the inner side of one of the support plates, one end of the threaded rod is movably connected to the inner side of the other support plate, two nuts are provided on the threaded rod, and the top of the nut is fixedly connected to the bottom surface of the support plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The maintenance personnel climb onto the U-shaped support plate via a step ladder and then onto the extension mechanism. When the front windshield needs to be repaired, the maintenance personnel enter the extension mechanism above the longitudinal plate in the U-shaped support plate, and the extension mechanism moves toward the front windshield, thereby shortening the distance between the front windshield and the longitudinal plate of the U-shaped support plate. The maintenance personnel can get closer to the front windshield, thereby avoiding a large distance between the nose of the aircraft and the U-shaped support plate, which makes it inconvenient for the maintenance personnel to perform maintenance. Moreover, for small aircraft, it is easier to approach for maintenance and prevent the maintenance personnel from falling through the gap between the nose of the aircraft and the U-shaped support plate. Similarly, the windshields on both sides of the nose of the aircraft are also extended by the extension mechanism, so that the maintenance personnel are closer, which is convenient for repairing the aircraft windshield.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0015] An aircraft windshield maintenance platform, such as Figure 1As shown in the figure, it includes a U-shaped support plate 1. Several legs 2 are fixedly installed on the bottom surface of the U-shaped support plate 1. A ladder is installed on one side of the U-shaped support plate 1. Three extension mechanisms are slidably installed on the top surface of the U-shaped support plate 1. The extension mechanisms extend towards the nose of the aircraft. The three extension mechanisms are arranged in a "pin" shape, that is, two of the extension mechanisms extend towards the side windshield of the aircraft nose, and the remaining one extension mechanism extends towards the front windshield of the aircraft nose. A protective plate is installed on the outer periphery of the U-shaped support plate, and it is not installed on the side close to the aircraft. Maintenance personnel climb onto the U-shaped support plate 1 through the ladder and then onto the extension mechanisms. When it is necessary to repair the front windshield, the maintenance personnel enter the extension mechanism above the longitudinal plate of the U-shaped support plate 1. The extension mechanism moves towards the front windshield, shortening the distance between the front windshield and the longitudinal plate of the U-shaped support plate 1. The maintenance personnel can get closer to the front windshield, avoiding a large distance between the aircraft nose and the U-shaped support plate 1, which is not convenient for maintenance personnel to carry out maintenance. Moreover, for small aircraft, it is better to approach for maintenance, preventing maintenance personnel from falling through the gap between the aircraft nose and the U-shaped support plate 1. Similarly, for the side windshields on both sides of the aircraft nose, through the extension of the extension mechanisms, the distance of the maintenance personnel is closer, facilitating the maintenance of the aircraft windshields.

[0016] Specifically, three groups of groove sets 3 are opened on the top surface of the U-shaped support plate 1 described in this embodiment. Each group of groove sets 3 is composed of two grooves. A screw 4 with a motor is movably installed in each groove. Two nuts are threadedly fitted on the screw 4. The tops of the nuts in the same group of groove sets 3 are connected to a group of extension mechanisms. The two motors in the same groove set rotate synchronously. The motors are connected to a controller and a processor. The wireless remote control module controls the processor and the controller. The groove set on the transverse plate of the U-shaped support plate is perpendicular to the groove set on the longitudinal plate. The extension mechanism on the transverse plate of the U-shaped support plate 1, under the rotation of the screw 4, the nut drives the extension mechanism to move horizontally to adjust the position of the extension mechanism. Similarly, for the extension mechanism on the longitudinal plate of the U-shaped support plate 1, under the rotation of the screw 4, the nut drives the extension mechanism to move longitudinally to adjust the position of the extension mechanism according to the usage needs of the maintenance personnel.

[0017] Furthermore, the extension mechanism described in this embodiment includes a base plate 5, the top end of the nut is fixedly connected to the bottom surface of the base plate 5, a lifting assembly is installed on the top surface of the base plate 5, a placement plate 6 is installed on the top surface of the lifting assembly, and a moving assembly is slidably installed on the top surface of the placement plate 6. The extension of the lifting assembly can control the placement plate 6 to adjust its height, drive the moving assembly to adjust its height, and enable maintenance personnel standing on the moving assembly to perform maintenance on the top of the windshield, that is, it is more convenient for maintenance personnel with shorter height. A TOF laser radar and a capacitive proximity sensor are installed on the placement plate 6, and a pressure sensing strip (sensitivity 50g) is installed at the end of the extension mechanism. The brake is triggered instantly when it contacts the aircraft. Through the TOF laser radar, the capacitive proximity sensor and the pressure sensing strip, the placement plate 6 can be prevented from colliding with the nose of the aircraft, thereby preventing damage to the nose of the aircraft.

[0018] Furthermore, the lifting assembly described in this embodiment includes several cylinders 7. The fixed bottom ends of the cylinders 7 are mounted on the top surface of the base plate 5, and the movable top ends of the cylinders 7 are fixedly connected to the bottom surface of the placement plate 6. The cylinders 7 are connected to a controller and a processor. A wireless remote control module can control the extension or retraction of the cylinders 7. When the cylinders 7 are extended, they push the placement plate 6 upward to adjust the height of the movable assembly.

[0019] Furthermore, the moving assembly described in this embodiment includes two groups of support plate groups 8, and the two groups of support plate groups are respectively located on both sides of the placement plate 6. Each group of support plate groups consists of two support plates. The two support plates in each group of support plate groups are respectively located at the front and rear ends of the placement plate 6. The bottom end of the support plate is fixedly connected to the top surface of the placement plate 6. A control component is installed between the two support plates in each group of support plate groups. A support plate 9 is arranged above the two groups of support plate groups, and the bottom end of the support plate 9 is connected to the two groups of control components. Guardrails are fixedly installed on three sides of the top surface of the support plate 9. The side of the top surface without guardrails is close to the nose of the aircraft, and a door is installed on one of the guardrails to facilitate the entry of maintenance personnel. The U-shaped support plate 1 is used as an example to illustrate the movable component above the front horizontal plate. The placement plate 6 moves left and right. After adjusting the position, the control component controls the support plate 9 to move back and forth, that is, controls the support plate 9 to move toward the side windshield of the aircraft, so that the support plate 9 is closer to the side windshield, and the maintenance personnel can be closer to the side windshield, which is convenient for maintenance. For aircraft of different sizes, maintenance can be better performed.

[0020] Furthermore, the control element of this embodiment includes a threaded rod with a motor. The motor of the threaded rod is fixedly mounted on the inner side of one of the support plates. One end of the threaded rod is movably connected to the inner side of the other support plate. Two nuts are threadedly engaged on the threaded rod, and the top ends of the nuts are fixedly connected to the bottom surface of the support plate 9. The nuts are positioned relative to the support plate as follows: the nut is located on the side of the support plate away from the aircraft, that is, in the transverse plate in front of the U-shaped support plate; the nut is located in the front half of the bottom of the support plate, in the transverse plate behind the U-shaped support plate; the nut is located in the rear half of the bottom of the support plate, in the longitudinal plate of the U-shaped support plate; and the nut is located in the right half of the support plate. The motor of the threaded rod is connected to the controller and processor and is controlled by a wireless control module. The motors of the two threaded rods rotate synchronously, controlling the rotation of the threaded rods, causing the nuts to rotate along the threaded rods, and controlling the support plate 9 to move toward the aircraft windshield, thereby extending the maintenance area. For small aircraft maintenance, there is no need to replace the maintenance platform, and the maintenance platform can be adjusted according to the distance between the aircraft and the maintenance platform. There is no need to adjust the maintenance platform or the aircraft, which is more convenient during maintenance.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
