Description

Technical Field

[0001] This utility model relates to the field of aircraft lifting technology, specifically to an aircraft jack. Background Technology

[0002] Aircraft jacks are specialized lifting devices, typically characterized by their lightweight yet robust structure, flexibility, and reliability, making them easy for one person to carry and operate. They utilize rigid lifting components as their working mechanism, lifting heavy objects within a short stroke via a top support or bottom claws. Aircraft jacks are primarily used for lifting operations during aircraft maintenance, such as changing tires or landing gear. Different types of jacks are suitable for different maintenance scenarios and lifting requirements. For example, wheel axle jacks are mainly used for tire changes in aircraft maintenance, while tripod jacks are primarily used for landing gear replacements. In summary, aircraft jacks are lifting devices with a special structure and function, capable of meeting the high demands of aircraft maintenance processes.

[0003] Aircraft jacks are primarily used to support and lift aircraft to facilitate necessary operations during maintenance, inspection, or component replacement. Due to their lightweight yet robust structure, they can be carried and operated by a single person, making them ideal for use at aircraft maintenance sites. Using jacks significantly improves the efficiency of aircraft maintenance work. Jacks can quickly and accurately lift aircraft, providing maintenance personnel with sufficient working space. Simultaneously, the use of jacks reduces safety risks during maintenance, ensuring the safety of maintenance personnel. In summary, aircraft jacks play a crucial role in aircraft maintenance. They not only possess basic functions such as support and lifting, tire and landing gear replacement, but also improve work efficiency and safety. However, when using jacks, they need to be assembled and secured with extension parts. This assembly process requires multiple connectors, making it relatively cumbersome. Furthermore, the compressive strength of the extension parts cannot be monitored in real time during use, which can easily lead to damage. Therefore, there is a certain degree of instability in their use. Utility Model Content

[0025] Example 1

[0026] Reference Figure 1-5 This is the first embodiment of the present invention, which provides an aircraft jack, including a jack 1 for lifting an aircraft, a tripod 2, and a controller 3. The jack 1 is located on top of the tripod 2 and is fixedly connected to the top of the tripod 2. The controller 3 is located on top of the tripod 2 and is fixedly connected to the top of the tripod 2. The controller 3 is electrically connected to the jack 1.

A pressure mechanism 6 for use with the jack 1 is provided on the top of the extension mechanism 4.

[0027] Specifically, the assembly mechanism 5 enables the expansion mechanism 4 to be quickly assembled and fixed with the jack 1, and the adjustment mechanism 7 enables the pressure mechanism 6 to be quickly adjusted according to usage requirements, thereby achieving the effect of quickly assembling and fixing the expansion mechanism 4 and monitoring the expansion mechanism 4 in real time through the pressure mechanism 6.

[0028] Furthermore, the extension mechanism 4 is connected to the jack 1. After the connection process, the extension mechanism 4 and the jack 1 can be assembled and fixed by the assembly mechanism 5. After the fixing is completed, the position of the pressure mechanism 6 can be quickly adjusted by the adjustment mechanism 7, so as to assist the use of the jack 1 and the extension mechanism 4.

[0029] Example 2

[0030] In the second embodiment of this utility model, the expansion mechanism 4 includes a conical block 401, a plug-in block 402, and a fixing plate 403. The conical block 401 is located at the top of the jack 1 and is fixedly connected to the top of the jack 1. The plug-in block 402 is located at the top of the conical block 401 and is fixedly connected to the top of the conical block 401. The inner cavity at the bottom of the fixing plate 403 is plugged into and fitted with the surface of the plug-in block 402.

The two connecting plates 502 are located on the left and right sides of the bottom of the fixing plate 403 respectively and are fixedly connected to the bottom of the fixing plate 403. The surface of the positioning screws 501 is threadedly connected to the inner cavity of the connecting plates 502. The two positioning grooves 503... The positioning screw 501, located on the left and right sides of the plug-in block 402, passes through the connecting plate 502 and is inserted into the inner cavity of the positioning groove 503, and is threadedly connected to the inner cavity of the positioning groove 503. The pressure mechanism 6 includes two movable blocks 601, two pressure sensors 602, and a data receiver 603. The two movable blocks 601 are located on the left and right sides of the top of the fixed plate 403, respectively. The pressure sensors 602 are located on the top of the movable blocks 601 and are fixedly installed on the top of the movable blocks 601. The data receiver 603 is located on the top of the fixed plate 403 and is fixedly connected to the top of the fixed plate 403. The two pressure sensors 602 are electrically connected to the data receiver 603 through data connection lines.

[0031] Specifically, the assembly mechanism 5 enables the extension mechanism 4 to be quickly assembled and fixed with the jack 1, and after assembly, the pressure mechanism 6 can monitor the compressive strength of the extension mechanism 4 in real time.

[0032] Furthermore, the fixing plate 403 is connected to the plug-in block 402 and the conical block 401. After the fixing plate 403 and the plug-in block 402 are connected, the positioning screw 501 is rotated. The positioning screw 501 will quickly insert into the inner cavity of the positioning groove 503 through its cooperation with the connecting plate 502. After the positioning screw 501 is inserted into the inner cavity of the positioning groove 503, the fixing plate 403 and the plug-in block 402 can be quickly assembled and fixed through the threaded connection with the positioning groove 503. After the fixing plate 403 is assembled, the pressure resistance of the expansion mechanism 4 can be monitored in real time through the pressure sensors 602 on both sides, and the data is transmitted to the inside of the data receiver 603 through the data connection line, and the pressure resistance is displayed through the data receiver 603.

[0033] Example 3

[0034] In the third embodiment of this utility model, the adjusting mechanism 7 includes a lead screw 701, a moving block 702, and a turntable 703. The lead screw 701 is located in the inner cavity of the fixed plate 403 and is movably connected to the inner cavity of the fixed plate 403 via a rotating shaft. The moving block 702 is located in the inner cavity of the fixed plate 403 and is threadedly connected to the surface of the lead screw 701. The turntable 703 is located on the right side of the fixed plate 403 and is rotatably connected to the inner wall of the fixed plate 403. The left side of the turntable 703 is fixedly connected to the right side of the lead screw 701. Cylindrical rods 8 are fixedly connected to the left and right sides of the front and rear sides of the fixed plate 403. Baffles 9 are fixedly connected to the right side of the two cylindrical rods 8. The surface of the cylindrical rods 8 is slidably connected to the inner cavity of the moving block 702.

[0035] Specifically, the adjustment mechanism 7 can quickly adjust the monitoring position of the pressure mechanism 6 according to the usage requirements, thus avoiding the situation where the pressure mechanism 6 cannot be adjusted according to the usage requirements.

[0036] Furthermore, after the fixed plate 403 is assembled, the turntable 703 is rotated. The turntable 703 drives the lead screw 701 to rotate through the connection end with the lead screw 701. During the rotation, the lead screw 701 adjusts its position through the threaded connection with the moving block 702. During the movement, the moving block 702 maintains its movement stability through the cylindrical rod 8. During the movement, the moving block 702 drives the pressure sensor 602 to adjust its position through the movable block 601. After adjusting to the appropriate position, the turntable 703 is stopped, causing the lead screw 701 to lose its rotational torque. Then, the position of the moving block 702 can be locked and fixed through the threaded connection between the lead screw 701 and the moving block 702, thus completing the position adjustment of the pressure sensor 602.

[0037] Working principle:

[0038] The fixing plate 403 is aligned with the insertion block 402 and the conical block 401. After the fixing plate 403 and the insertion block 402 are aligned, the positioning screw 501 is rotated. The positioning screw 501, through its cooperation with the connecting plate 502, quickly inserts into the inner cavity of the positioning groove 503. After the positioning screw 501 is inserted into the inner cavity of the positioning groove 503, the threaded connection with the positioning groove 503 achieves the effect of quick assembly and fixation of the fixing plate 403 and the insertion block 402. After the fixing plate 403 is assembled, the turntable 703 is rotated. The turntable 703 drives the lead screw 701 to rotate through its connection with the lead screw 701. During the rotation, the lead screw 701 adjusts its position through its threaded connection with the moving block 702. During its movement, the movable block 702 maintains its stability via the cylindrical rod 8. Simultaneously, the movable block 702, through the movable block 601, drives the pressure sensor 602 to adjust its position. Once adjusted to the appropriate position, the rotating turntable 703 stops rotating, causing the lead screw 701 to lose its rotational torque. The threaded connection between the lead screw 701 and the movable block 702 then locks and fixes the position of the movable block 702, thus completing the position adjustment of the pressure sensor 602. This allows for real-time monitoring of the pressure resistance of the extension mechanism 4 via the pressure sensors 602 on both sides, and the data is transmitted to the data receiver 603 via a data connection cable for display of the pressure resistance.

[0039] In summary, through the cooperation of jack 1, tripod 2, controller 3, extension mechanism 4, assembly mechanism 5, pressure mechanism 6 and adjustment mechanism 7, the effects of rapid assembly of the extension parts and real-time monitoring of the pressure resistance of the extension parts are achieved.
