[0028] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.
[0029] Reference Figure 1 An embodiment of the present invention provides a device for automatically releasing an aircraft standard block, comprising: a plane leveling component and a standard block clamping component arranged below the plane leveling component.
[0030] Among them, the plane leveling component includes a main frame 1, a rotating shaft 2, a linear telescopic member 3, and an elastic pushing mechanism; the rotating shaft 2 is arranged horizontally and its end is rotatably connected to one side of the main frame 1, the linear telescopic member 3 is arranged on the main frame 1, the telescopic direction of the linear telescopic member 3 is the vertical direction, and the movable end of the linear telescopic member 3 is connected to the elastic pushing mechanism. The device realizes the adaptive leveling function of the ground through the plane leveling component. The horizontal arrangement of the rotating shaft 2 and the rotational connection with the main frame 1 allow the device to adjust its posture within a certain range to adapt to the uneven cabin surface. The vertical telescopic ability of the linear telescopic member 3, combined with the elastic pushing mechanism, can further fine-tune the height and posture of the device, thereby driving the standard block clamping assembly to move downward so that the clamping sleeve 4 coincides with the reference plane on the ground, ensuring that the standard block is in a stable and horizontal state before release.
[0031] The standard block clamping assembly includes a clamping sleeve 4 and a clamping member 5; the clamping sleeve 4 is arranged below the main frame 1 and is vertically slidably connected to the main frame 1, the elastic pushing mechanism is arranged inside the clamping sleeve 4, the elastic pushing mechanism is connected to the clamping sleeve 4, the clamping member 5 is arranged on the side wall of the clamping sleeve 4, and is used to fix the standard block on the clamping sleeve 4, and the elastic pushing mechanism can push the standard block out of the clamping sleeve 4. The standard block clamping assembly adopts a combination design of the clamping sleeve 4 and the clamping member 5, which effectively ensures the stability of the standard block in the process of waiting for release. The vertical sliding connection of the clamping sleeve 4 allows it to move close to the reference plane under the push of the linear telescopic member 3 and the elastic pushing mechanism.
[0032] The elastic pushing mechanism is not only used to push the standard block out of the clamping sleeve 4 to achieve automatic release, but also provides a certain buffering effect during the clamping process to prevent the standard block from loosening or being damaged due to external impact or vibration.
[0033] The design of the device simplifies the clamping and releasing process of the standard block and reduces the need for manual intervention. Through the synergistic effect of the linear telescopic member 3 and the elastic push mechanism, the standard block can be released quickly and accurately, improving the working efficiency. The improvement of the degree of automation also means that the errors and risks caused by human operation are reduced, making the entire release process more reliable and accurate.
[0034] In some embodiments, the elastic pushing mechanism includes a slider 6 and a spring 7. The top of the slider 6 is fixedly connected to the movable end of the linear telescopic member 3, the spring 7 is sleeved on the slider 6, and a first step is provided at one end of the slider 6 close to the linear telescopic member 3, the top of the spring 7 is in contact with the first step, and the bottom of the spring 7 is connected to the clamping sleeve 4.
[0035] In the above embodiment, referring to Figure 2 , the top of the slider 6 is fixedly connected to the movable end of the linear telescopic member 3, ensuring that the linear telescopic member 3 can stably transmit the thrust to the slider 6 during the telescopic process. This design makes the thrust transmission path clear and efficient, reducing energy loss and transmission error. The spring 7 is sleeved on the slider 6 and abuts against the top of the slider 6 through the first step, forming a flexible thrust buffer mechanism. When the linear telescopic member 3 pushes the slider 6 downward, the spring 7 is compressed, so that the spring 7 pushes the clamping sleeve 4 downward. When the bottom point or edge line of the clamping sleeve 4 contacts the reference plane, the spring 7 continues to press downward so that the bottom surface of the entire clamping sleeve 4 fits the reference plane, achieving the effect of leveling; as the slider 6 continues to move downward, the slider 6 passes through the clamping sleeve 4 and pushes the standard block out, achieving the effect of releasing the standard block.
[0036] The combined design of the slider 6 and the spring 7 simplifies the structure of the elastic push mechanism and reduces the number and complexity of parts. This not only reduces the manufacturing cost and maintenance difficulty, but also improves the reliability and durability of the device. In addition, this design also facilitates the replacement and maintenance of the elastic push mechanism, reducing the operation and maintenance cost and time cost. The automatic rebound characteristic of the spring 7 enables the clamping sleeve 4 to quickly reset as the linear telescopic member 3 retracts after releasing the standard block, preparing for the next clamping operation. This automatic reset function improves the automation of the device and reduces the need for manual intervention.
[0037] In some embodiments, the bottom surface of the clamping sleeve 4 is a plane, and the clamping sleeve 4 has a first cavity 8 and a second cavity 9. The first cavity 8 and the second cavity 9 are coaxially arranged, and the first cavity 8 is arranged above the second cavity 9. The first cavity 8 and the second cavity 9 are connected to each other. The spring 7 is located in the first cavity 8, and a second step is provided at the junction of the first cavity 8 and the second cavity 9. The bottom end of the spring 7 is connected to the second step, and the end of the slider 6 away from the linear telescopic member 3 can pass through the second step and enter the second cavity 9.
[0038] In the above embodiment, the coaxial arrangement of the first cavity 8 and the second cavity 9 ensures the stable installation and movement of the spring 7 and the slider 6 in the clamping sleeve 4. This structural design makes the compression and release process of the spring 7 smoother, avoiding the problem of structural failure or unstable clamping force caused by uneven force. The setting of the second step provides a stable support point for the spring 7. The design of the clamping sleeve 4 with this coaxial structure makes the replacement and maintenance of the spring 7 and the slider 6 more convenient. When the spring 7 or the slider 6 needs to be replaced, it is only necessary to disassemble some components of the clamping sleeve 4 without disassembling the entire device.
[0039] In some embodiments, the second cavity 9 is used to place the standard block, and the clamping member 5 includes a screw, which is arranged on the side wall of the clamping sleeve 4, and one end of the screw can be inserted into the second cavity 9 to abut against the standard block. The second cavity 9 provides a stable placement space for the standard block, ensuring that the position of the standard block in the clamping sleeve 4 is fixed. This design reduces the release error caused by the shaking or movement of the standard block. The screw is used as a clamping member 5, and one end of it can be inserted into the second cavity 9 to directly abut against the standard block, thereby achieving accurate clamping and fixing of the standard block. By adjusting the tightening degree of the screw, the size of the clamping force can be further controlled to ensure the stability of the standard block during transportation and waiting for release. The design of the screw makes the assembly and disassembly of the standard block convenient. When the standard block needs to be released, it is only necessary to loosen the screw to facilitate the slider to push the standard block out of the second cavity 9. Similarly, when a new standard block needs to be clamped, it is only necessary to put the standard block into the second cavity 9 and tighten the screw. This convenient assembly and disassembly operation not only improves the operating efficiency, but also reduces the difficulty of operation and labor costs.
[0040] In some embodiments, the second cavity 9 is used to place the standard block, and the clamping member 5 includes a spring pin, which is arranged on the side wall of the clamping sleeve 4, and one end of the spring pin is located in the second cavity 9 for contacting the standard block. Compared with screws, the spring pin of this embodiment does not need to be manually tightened or loosened by the operator, which is very convenient.
[0041] In some embodiments, the rotating shaft 2 has a transverse shaft section 10 and a connecting shaft section 11, the transverse shaft section 10 is connected to the connecting shaft section 11, the axes of the transverse shaft section 10 and the connecting shaft section 11 are set at an angle of 15 degrees to 85 degrees, the transverse shaft section 10 is rotatably connected to the main frame 1, and the connecting shaft section 11 is used to connect to an external device so that the rotating shaft 2 remains fixed. The angle design between the transverse shaft section 10 and the connecting shaft section 11 of the rotating shaft 2 enables the device to adjust the angle within a certain range. This adjustment capability enhances the flexibility of the device and enables it to adapt to the needs of different operating environments. The connection between the connecting shaft section 11 and the external device ensures the stability of the rotating shaft 2 during operation. This fixing method effectively prevents the shaking or displacement of the rotating shaft 2 due to uneven force or external impact. The angle design of the rotating shaft 2 makes the device more compact and reasonable in spatial layout. This layout not only reduces the space occupied by the cabin, but also improves the operating efficiency.
[0042] In some embodiments, a sliding sleeve 12 is sleeved on the transverse shaft section 10 , the sliding sleeve 12 is rotatably connected to the transverse shaft section 10 , and an outer side wall of the sliding sleeve 12 is fixedly connected to the main frame 1 via screws.
[0043] In some embodiments, a limit block 13 is provided at the joint of the transverse shaft segment 10 and the connecting shaft segment 11. The limit block 13 has a vertical side wall which contacts the main frame 1. The limit block 13 is used to provide lateral support force.
[0044] In some embodiments, the linear telescopic member 3 comprises a linear motor.
[0045] In some embodiments, the clamping sleeve 4 is slidably connected to the main frame 1 via a vertical slide rail.
[0046] The device for automatically releasing the aircraft standard block in the above embodiment has the following advantages and technical effects:
[0047] 1. The device realizes the adaptive leveling function of the ground through the plane leveling component. The horizontal setting of the rotating shaft 2 and the rotation connection with the main frame 1 allow the device to adjust its posture within a certain range to adapt to the uneven cabin surface.
[0048] 2. The vertical telescopic ability of the linear telescopic member 3, combined with the elastic driving mechanism, can further fine-tune the height and posture of the device, thereby driving the standard block clamping assembly to move downward so that the ground of the clamping sleeve 4 coincides with the reference plane, ensuring that the standard block is in a stable and horizontal state before release.
[0049] 3. The standard block clamping assembly adopts a combination design of a clamping sleeve 4 and a clamping member 5, which effectively ensures the stability of the standard block while waiting for release. Through the synergistic effect of the linear telescopic member 3 and the elastic pushing mechanism, the standard block can be released quickly and accurately, improving the working efficiency.
