Description

Technical Field

[0001] The invention relates to the technical field of aviation ground equipment, and in particular to a synchronous lifting electric jack device which can be laser-centered and automatically leveled. Background Art

[0002] Aircraft jacks are widely used in aircraft factories, aircraft maintenance companies, airports, hangars and other places. They are mainly used to support and lift aircraft to ensure the smooth progress of related work. They are important ground support equipment that is indispensable in aircraft assembly and manufacturing, tire replacement, landing gear replacement and maintenance.

[0003] In situations such as aircraft assembly, replacement of aircraft landing gear, and landing gear retraction and extension experiments, the entire aircraft needs to be lifted up. The traditional operation process is: (i) Find a nose tripod jack and two wing jacks with rated load, minimum height and maximum height that meet the requirements; (ii) Each tripod jack shall be equipped with one operator and one assistant, and the entire aircraft shall be equipped with one aircraft attitude observer, for a total of seven persons; (3) Move each jack to the bottom of the corresponding jacking point of the aircraft; (iv) Each operator extends the piston rod of the jack manually / pneumatically / hydraulicly and makes the top pad of the jack approach and align with the center of the jacking point of the aircraft by visual observation and manual movement; (5) The operator rotates the jack's anchor plate so that the three anchor plates are in contact with the ground and bear the weight, and the three universal wheels are off the ground and do not bear the weight; (6) The operator operates the jack to continue to rise slowly; (VII) The aircraft attitude observer obtains aircraft attitude information by observing the heading and span direction bubble meters installed inside the front landing gear compartment of the aircraft. When the aircraft heading and span direction tilt angles are out of tolerance, the observer eliminates the tilt by coordinating the speed of the three jacks rising; (8) The observer finally confirms that the aircraft has reached the predetermined operating altitude and has no tilt in heading and span direction; (IX) The jack operator locks the safety nut, the jack releases pressure through the pressure relief valve, the entire weight of the aircraft is borne by the safety nut, and the aircraft jacking operation is completed.

[0004] At present, the existing technology still has the following areas for improvement: (a) the positioning between the jack and the aircraft jacking point is performed by visual observation and manual fine-tuning, which is inefficient; (ii) The final attitude of the aircraft is observed through a horizontal bubble instrument, which has low accuracy; (3) The entire operation process takes at least one hour, which is inefficient and cannot meet the needs of mass production models; (4) At least seven people are required to work together, which results in high labor costs; (V) Each jack is an independent mechanical device that cannot be automated, cannot collect key data, and cannot be integrated into a digital aircraft production line.

[0050] The working principle and use process of the present invention are as follows: the detection component 2 is installed at the lower end of the machine head through the top suction cup 21, and the adjustment nut 26 is rotated to adjust the horizontality of the angle adjustment plate 24 so that the initial horizontality of the dual-axis inclination sensor 22 is adjusted to normal; Turn on the two wing laser centering devices 111 of the wing jack assembly 1. The intersection of the wing laser paths 11 of the two wing laser centering devices 111 is the midpoint of the wing jack assembly 1. The wing jack assembly 1 is moved and adjusted by the wing moving roller 120. The wing limit rod 121 and the wing anti-rotation rod 122 are both located in the limit grooves opened on the ground. The wing limit rod 121 is used to limit the movement range of the wing jack assembly 1. The wing anti-rotation rod 122 is used to prevent the rotation of the wing jack assembly 1. When the intersection of the wing laser paths 11 is located at a designated point at the lower end of the aircraft, the wing positioning plate 15 is rotated to retract the wing moving roller 120 into the wing adjuster 19, and the height of the wing adjuster 19 is adjusted to adjust the horizontality of the wing chassis 110. Turn on the two nose laser centering devices 311 of the nose jack assembly 3. The intersection of the nose laser paths 31 of the two nose laser centering devices 311 is the midpoint of the nose jack assembly 3. The nose jack assembly 3 is moved and adjusted by the nose moving roller 320. The nose limit rod 321 and the nose anti-rotation rod 322 are both located in the limit grooves opened on the ground. The nose limit rod 321 is used to limit the movement range of the nose jack assembly 3. The nose anti-rotation rod 322 is used to prevent the rotation of the nose jack assembly 3. When the intersection of the nose laser paths 31 is located at a designated point at the lower end of the aircraft, the nose positioning plate 35 is rotated to retract the nose moving roller 320 into the nose adjuster 39. The height of the nose adjuster 39 is adjusted to adjust the horizontality of the nose chassis 310. Connect the detection assembly 2, the nose jack assembly 3 and the two wing jack assemblies 1 to the cable connector 47 of the control cabinet assembly 4 through cables, and start them through the control button 43 and the control knob 49; The wing hydraulic pump 13 is started, and high-pressure hydraulic oil is pressed into the wing threaded piston rod 117 through the wing hydraulic pump 13, driving the wing threaded piston rod 117 to rise. At the same time, the wing height measuring device 125 is started to extend the wing telescopic rod 124, driving the wing measuring rope 123 to extend, thereby measuring the rising height value of the aircraft, and transmitting the height value to the display screen 42. The wing telescopic rod 124 prevents the wing threaded piston rod 117 from rotating; When the aircraft rises to the designated height, the wing hydraulic pump 13 is stopped, and the wing motor is started to rotate the wing driving gear 114, thereby driving the wing adjusting gear 115 to rotate. Since the wing adjusting gear 115 is meshed with the wing threaded piston rod 117, and the wing threaded piston rod 117 is in a stopped state, the wing adjusting gear 115 moves downward to contact the upper end of the wing piston cylinder 18, and the weight of the aircraft is supported by the wing piston cylinder 18 and the wing support rod 14; At the same time, the nose hydraulic pump 33 is started, and the high-pressure hydraulic oil is pressed into the nose threaded piston rod 317 through the nose hydraulic pump 33, driving the nose threaded piston rod 317 to rise. At the same time, the nose height measuring device 325 is started to extend the nose telescopic rod 324, driving the nose measuring rope 323 to extend, thereby measuring the ascent height value of the aircraft, and transmitting the height value to the display screen 42. The nose telescopic rod 324 prevents the nose threaded piston rod 317 from rotating. When the aircraft rises to the specified height, the nose hydraulic pump 33 is stopped, and the nose motor is started to rotate the nose driving gear 314, driving the nose adjusting gear 315 to rotate. Since the nose adjusting gear 315 is meshed with the nose threaded piston rod 317, and the nose threaded piston rod 317 is in a stopped state, the nose adjusting gear 315 moves downward to contact the upper end of the nose piston cylinder 38, and the weight of the aircraft is supported by the nose piston cylinder 38 and the nose support rod 34, driving the aircraft to rise at the same time; At the same time, the dual-axis tilt sensor 22 can detect the horizontality of the X-axis and Y-axis of the aircraft and transmit the detection data to the display screen 42; When it is necessary to descend, the pressure relief solenoid valve is activated, and under the action of gravity, the wing threaded piston rod 117 and the nose threaded piston rod 317 are automatically lowered to complete the descent operation of the aircraft; By controlling the opening of the proportional solenoid valve, the flow rate of the hydraulic oil can be controlled, thereby controlling the rising and falling speed of the wing threaded piston rod 117.
