Description

Technical Field

[0001] This utility model relates to the field of aircraft emergency slide technology, and in particular to an aircraft emergency slide packaging device. Background Technology

[0002] Aircraft emergency slides are devices used to quickly evacuate aircraft passengers in emergencies. They are typically located at the emergency exits of an aircraft and can be quickly deployed in an emergency to form a safe, sloped slide for passengers to slide off the aircraft. Aircraft emergency slides are usually made of high-strength materials with fire resistance, wear resistance, and tensile strength to ensure safe and effective use in emergencies. During the packaging of the slides, workers found it difficult to stack the slide materials into an ideal shape, resulting in excessively high stacking heights. When compressing the slides, the industry typically uses manual pulling of tensioners, especially for A320 slides (part number D30664 / 5), where manual operation is difficult and cannot be accomplished by a single person; several people are required to pull the tensioners simultaneously. Utility Model Content

[0003] The purpose of this invention is to solve at least one of the technical problems existing in the prior art by providing an aircraft emergency slide packing device. The device involves placing the emergency slide to be packed onto a movable plate, then rotating a screw rod on the movable plate to cause a threaded sliding frame to clamp the emergency slide, ensuring that the slide will not shift during packing. Next, a motor on a fixed frame rotates a screw rod, allowing the threaded movable plate to move the emergency slide under a movable steel pressure plate. Users only need to place the emergency slide onto the movable plate, eliminating the need for manual placement and avoiding potential safety risks. Finally, a bidirectional hydraulic jack is used to press the slide to a predetermined height. After locking the height, the hydraulic jack is reversed to complete the packing operation, solving the current problem of difficulty in manual packing and improving packing efficiency.

[0004] This utility model also provides an aircraft emergency slide packing device, comprising: a device body, a bidirectional hydraulic jack installed inside the device body, a movable steel pressure plate fixedly connected to the output end of the bidirectional hydraulic jack, a fixed frame fixedly connected to the lower bottom wall of the device body, a motor fixedly connected to the outer surface of the fixed frame, a lead screw one fixedly connected to the output end of the motor, a movable plate threadedly connected to the outer surface of the lead screw one, a lead screw two rotatably connected to the outer surface of the movable plate, a sliding frame threadedly connected to the outer surface of the lead screw two, a sliding frame slidably connected to the outer surface of the sliding frame and the movable plate, and a clamping plate fixedly connected to the outer surface of the sliding frame.

[0005] According to the aircraft emergency slide packaging equipment of this utility model, the emergency slide is placed on the upper surface of the movable plate, and the outer surface of the clamping plate abuts against the outer surface of the emergency slide. The close contact between the clamping plate and the emergency slide can firmly fix the slide and prevent the slide from shifting during the packaging process.

[0006] According to the aircraft emergency slide packaging equipment of this utility model, the inner wall of the fixing frame is fixedly connected with a guide rod, and the outer surface of the guide rod is slidably connected to the moving plate. The guide rod provides good guidance, making the moving plate move more smoothly.

[0007] According to the aircraft emergency slide packing device of this utility model, the inner wall of the movable steel pressure plate is fixedly connected with a bearing, and the inner wall of the bearing is slidably connected with a shaft, which provides good guidance and realizes the smooth lifting and lowering of the movable steel pressure plate.

[0008] According to the aircraft emergency slide packaging device of this utility model, the two ends of the shaft are fixedly connected to the main body of the device, and the position of the movable steel pressure plate is located above the emergency slide, which ensures that the movable steel pressure plate can always be accurately aligned with the emergency slide, thus helping to improve the packaging accuracy.

[0009] According to the aircraft emergency slide packaging equipment of this utility model, a protective cover is fixedly connected to the outer surface of the fixing frame, and the motor is located inside the protective cover. The protective cover can effectively prevent external influence on the motor and improve the safety and service life of the motor.

[0010] According to the aircraft emergency slide packing device of this utility model, the outer surface of the protective cover is provided with heat dissipation vents, and one end of the lead screw is rotatably connected to the fixed frame. The design of the heat dissipation vents can promote air circulation, prevent the motor from being damaged due to overheating during the operation of the equipment, and keep the motor at the optimal operating temperature.

[0011] According to the aircraft emergency slide packing device of this utility model, the inner wall of the fixed frame is slidably connected to the movable plate, and the lower surface of the movable plate is in contact with the main body of the device. The sliding connection between the movable plate and the fixed frame makes the movable plate move more flexibly and freely when it moves.

[0012] Beneficial effects

[0013] 1. Compared with existing technologies, this aircraft emergency slide packing equipment places the emergency slide to be packed onto a movable plate, and then rotates the second screw on the movable plate, causing the threaded sliding frame to drive the clamping plate to hold the emergency slide, ensuring that the emergency slide will not shift during packing; then, the motor on the fixed frame rotates the first screw, allowing the threaded movable plate to move the emergency slide under the movable steel pressure plate. Users only need to place the emergency slide on the movable plate, without having to manually put it into the equipment, thus avoiding potential safety risks.

[0014] 2. Compared with existing technologies, this aircraft emergency slide packing equipment uses a two-way hydraulic jack to press the slide to a predetermined height. After locking the height of the emergency slide, the hydraulic jack is operated in reverse to complete the packing operation, which solves the current problem of difficulty in manual packing and improves packing efficiency.
