Problems solved by technology

In actual operation, the tires of the aircraft landing gear are affected by various hazards, and there will be tire blowouts and brake lock failures.
When the aircraft has a tire blowout or brake lock, the usual fault handling method is: use a jack or a lifting device to lift the faulty tire off the ground at the fault rescue site, and then replace the tire and troubleshoot. The problem with this method is that on-site troubleshooting can only be carried out on the airport runway, and the aircraft cannot be towed away from the runway or flight area. Moreover, it takes at least 40 minutes to replace a tire, thus occupying the airport runway for too long. It will affect the safety of subsequent landing or take-off aircraft, as well as the alternate landing scheduling of the entire air traffic control area, and may easily cause major indirect economic losses such as other flight delays.

Embodiment 1

[0028] like Figure 1-3 Shown: an aircraft landing gear failure emergency runway rescue device, including a U-shaped frame body 1 with a plurality of load-bearing universal wheels 14 at the bottom and an aircraft tire lifting mechanism and a locking mechanism arranged on the frame body 1, The frame body 1 is provided with an outer casing to prevent dust and rain and protect internal mechanical components. The lifting mechanism includes a lifting lever 12 arranged in the middle of the frame body 1. The middle part of the lifting lever 12 is hinged with the frame body 1. The front end is provided with a lifting plate 13 with a groove, and the rear end is connected with the frame body. The vertical telescopic hydraulic cylinder 10 on the body 1 is connected, and through leverage, when the vertical telescopic hydraulic cylinder 10 pushes the rear end of the lifting lever 12 downward, its front end rises, and the lifting lever placed in the groove of the lifting plate 13 Aircraft ...

Embodiment 2

[0030] like Figure 4 , Figure 5 As shown: the difference between this embodiment and the first embodiment is that the rear locking member 3 of the locking mechanism is arranged in the cavities on both sides of the frame body 1 through telescopic arms, and the rear locking parts 3 arranged in the cavity The lock hydraulic cylinder 21 is driven by forward and backward displacement. The telescopic arm includes a fixed arm 18 and two inner positioning movable arms 19 which are sequentially sleeved in the fixed arm 18. The telescopic hydraulic cylinder 20 is driven to realize telescopic movement, and the rear locking member 3 is arranged on the movable arm 19; the telescopic arm includes a corresponding left telescopic arm and a right telescopic arm, and the left and right telescopic arms pass through mutually matched positioning blocks It is positioned and docked with the positioning groove structure 23. The upper locking block of the front locking part 8 is connected with the...

Abstract

The invention discloses a rescue device for a failure emergency of separation of aircraft undercarriages from runways. The rescue device comprises a U-shaped frame body, and a lifting mechanism and a locking mechanism of an aircraft undercarriage, wherein a plurality of bearing universal wheels are arranged at the bottom of the U-shaped frame body; the lifting mechanism and the locking mechanism are arranged on the U-shaped frame body and are driven by hydraulic cylinders and motors to move, the frame body, the lifting mechanism and the locking mechanism can be formed by the welding of high-strength steel and high-strength alloy or the butting of high-strength bolts, and controllers are connected to the hydraulic cylinders and the motors so as to perform operation and control; the butting of the device and an aircraft only comprises locking operation and lifting operation, the butting can be completed within 5 minutes, and the situation that when the aircraft has tire burst, the aircraft can be drawn to leave a runway at the first time is realized. The rescue device disclosed by the invention has the advantages of reasonable design, compact layout, small size, high efficiency, high safety, high reliability, and high practicality.

Description

technical field [0001] The invention belongs to the technical field of aircraft emergency rescue, and in particular relates to a rescue device for emergency escape from a runway when an aircraft landing gear fails. Background technique [0002] The tires of the landing gear of the aircraft are an important part of the aircraft, and play a pivotal role in the parking of the aircraft and during the taxiing, lifting and landing of the aircraft to protect the safety of the aircraft. In actual operation, the tires of aircraft landing gear are affected by various hazards, and tire bursts and brake lock failures may occur. When the aircraft has a tire blowout or brake lock, the usual fault handling method is: use a jack or a lifting device to lift the faulty tire off the ground at the fault rescue site, and then replace the tire and troubleshoot. The problem with this method is that on-site troubleshooting can only be carried out on the airport runway, and the aircraft cannot be t...
