Abstract
Description
Technical Field
[0001] This application relates to the field of aircraft hydraulic jack technology, specifically an infrared-calibrated aircraft hydraulic jack. Background Technology
[0002] With the rapid development of the international aviation industry and the continuous emergence of modern new fighter jets, aircraft maintenance and personal safety are given top priority. This plays a crucial role in improving industry reputation, reducing economic costs, and saving the country a significant amount of intangible expenses. Due to the size of aircraft, large lifting equipment such as cranes cannot be used; therefore, smaller jacks are sufficient for aircraft support tasks.
[0003] Most aircraft hydraulic jacks directly lift and support the aircraft by controlling the hydraulic system. When lifting and supporting the aircraft, the jack head needs to be aligned with the aircraft's mounting base. However, since the aircraft chassis is low when not lifted, it is difficult to ensure that the jack head and mounting base are aligned when lifting the aircraft. This can easily cause wear on the aircraft surface and the hydraulic jack, and affect the lifting effect of the hydraulic jack. Therefore, an infrared calibration type aircraft hydraulic jack is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an infrared calibration aircraft hydraulic jack, which has advantages such as easy alignment and solves the problem of difficult alignment.
[0005] To achieve the above objectives, this application provides the following technical solution: an infrared calibration aircraft hydraulic jack, comprising a jack, a top head fixed to the output end of the jack, a support frame fixed to the outer surface of the jack, a rubber pad fixed to the top of the top head, and a calibration component provided at the top of the top head;
[0006] The calibration assembly includes an infrared alignment instrument, a base plate, a mounting plate, a mounting rod fixedly installed at the lower end of the infrared alignment instrument, and a telescopic structure fixedly installed on the opposite side of the mounting plate and the base plate.
[0007] By adopting the above technical solution, the jack has an infrared calibration function, which enables the jack head to make precise contact with the aircraft's top socket, improves the jack's support effect on the aircraft, and can effectively reduce wear on the aircraft surface and the jack itself, ensuring the lifting effect of the aircraft hydraulic jack on the aircraft, and facilitating the disassembly and replacement of the infrared alignment instrument.
[0008] Furthermore, both the base plate and the mounting plate are circular, with the base plate located at the bottom of the inner cavity of the top head and fixed thereto.
[0009] The above technical solution is adopted so that the base plate and the mounting plate can fit against the inner wall of the top head.
[0010] Furthermore, the top of the mounting plate is provided with a mounting hole for inserting a mounting rod into it, and multiple threads are provided on the outer surface of the mounting plate and the inner sidewall of the mounting hole.
[0011] By adopting the above technical solution, the mounting rod can be fixed in the mounting hole, so that the mounting rod can be installed on the mounting plate, and the infrared alignment instrument can be installed on the mounting plate, which facilitates the disassembly and replacement of the infrared alignment instrument.
[0012] Furthermore, the telescopic structure includes a column, a sliding column, a micro motor, two uprights, a horizontal plate fixedly installed on the inner wall of the sliding column, a lead screw fixedly installed on the output end of the micro motor, and two baffles fixedly installed on the top of the uprights to block the horizontal plate.
[0013] By adopting the above technical solution, the infrared alignment instrument can be moved in or out of the top head, avoiding contact between the infrared alignment instrument and the top recess of the aircraft when the top head lifts the aircraft, which would cause damage to the infrared alignment instrument due to the load pressure, thus improving its service life.
[0014] Furthermore, the column is a hollow cylinder with a missing upper end, the sliding column is a hollow cylinder with a missing lower end, and the micro motor and the two uprights are all fixed to the bottom wall of the inner cavity of the column.
[0015] By adopting the above technical solution, the micro motor, lead screw, and two uprights can all extend into the inner cavity of the slide column.
[0016] Furthermore, the diameter of the sliding column is smaller than the diameter of the upright column, and the ends of the sliding column opposite to the upright column are respectively fixed to the opposite walls of the base plate and the mounting plate.
[0017] The above technical solution allows the sliding column to move in or out of the column, so that the sliding column and the column can cooperate to form a telescopic column, which can adjust the distance between the base plate and the mounting plate.
[0018] Furthermore, the top of the horizontal plate is provided with a threaded hole for the lead screw to pass through it, and the lead screw is threaded to the inside of the threaded hole.
[0019] By adopting the above technical solution, the lead screw can be threadedly connected to the horizontal plate through the threaded hole, so that the lead screw can drive the horizontal plate to move up and down, thereby enabling the horizontal plate to drive the sliding column to move in or out of the column.
[0020] Furthermore, the top of the horizontal plate has a circular hole for two uprights to pass through it, and the uprights are slidably connected to the inside of the circular hole.
[0021] Using the above technical solution, the horizontal plate can slide on the outer surface of the two vertical rods through the two round holes, so that when the screw is threadedly connected to the threaded hole of the horizontal plate, the horizontal plate can restrict the screw from rotating through the two vertical rods, so that when the screw is threadedly connected to the threaded hole of the horizontal plate, it can only move up and down.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This infrared-calibrated aircraft hydraulic jack, equipped with a calibration component, features infrared calibration capabilities. This ensures precise contact between the jack head and the aircraft's mounting base, effectively reducing wear on the aircraft surface and the jack itself. This guarantees the lifting effect of the aircraft hydraulic jack and facilitates the removal and replacement of the infrared alignment instrument. Furthermore, the infrared alignment instrument can be retracted or moved out of the jack head, preventing damage to the instrument due to load pressure. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] Please see Figures 1 to 2The infrared calibration aircraft hydraulic jack in this embodiment includes a jack 1, a head 2 fixed to the output end of the jack 1, a support frame 3 fixed to the outer surface of the jack 1, a rubber pad 4 fixed to the top of the head 2, and a calibration component provided at the top of the head 2.
[0030] Additionally, it should be noted that the top head 2 is a hollow cylinder with a missing top, and the rubber pad 4 is also ring-shaped to avoid obstructing the calibration components.
[0031] Please see Figures 1 to 3 The calibration components in this embodiment include an infrared alignment instrument 51, a base plate 54, a mounting plate 53, a mounting rod 52 fixedly mounted on the lower end of the infrared alignment instrument 51, and a telescopic structure fixedly mounted on the opposite side of the mounting plate 53 and the base plate 54.
[0032] Both the base plate 54 and the mounting plate 53 are circular. The base plate 54 is located at the bottom of the inner cavity of the top head 2 and is fixed thereto, so that the base plate 54 and the mounting plate 53 can fit against the inner cavity wall of the top head 2. The mounting plate 53 can be fixed to the base plate 54 through a telescopic structure, so that the mounting plate 53 can be installed inside the top head 2. Thus, the infrared alignment instrument 51 can be installed on the top head 2 through the mounting plate 53, which enables the top head 2 of the jack 1 to have an alignment function, effectively improving the accuracy of the alignment between the top head 2 and the top socket.
[0033] Furthermore, the top of the mounting plate 53 has a mounting hole for inserting the mounting rod 52 into it. The outer surface of the mounting plate 53 and the inner wall of the mounting hole are both threaded. The thread of the mounting rod 52 is threadedly connected to the thread inside the mounting hole, so that the mounting rod 52 can be fixed in the mounting hole. Thus, the mounting rod 52 can be installed on the mounting plate 53, and the infrared alignment instrument 51 can be installed on the mounting plate 53, which facilitates the disassembly and replacement of the infrared alignment instrument 51.
[0034] Please see Figures 2 to 3 The telescopic structure in this embodiment includes a column 55, a sliding column 56, a micro motor 57, two uprights 510, a horizontal plate 59 fixedly installed on the inner wall of the sliding column 56, a lead screw 58 fixedly installed on the output end of the micro motor 57, and two baffles 511 fixedly installed on the top of the uprights 510 to block the horizontal plate 59. The baffles 59 can effectively prevent the horizontal plate 59 from falling off the outer surface of the lead screw 58 when it moves upward on the outer surface of the lead screw 58. In addition, a circular groove is provided at the lower end of the horizontal plate 59 so that the top end of the lead screw 58 can rotate within the baffles 511 through the circular groove, so as to prevent the baffles 511 from obstructing the lead screw 58 during the rotation process.
[0035] Secondly, the column 55 is a hollow cylinder with a missing upper end, and the slide column 56 is a hollow cylinder with a missing lower end. The micro motor 57 and the two uprights 510 are all fixed to the bottom wall of the inner cavity of the column 55, so that the micro motor 57, the lead screw 58 and the two uprights 510 can all extend into the inner cavity of the slide column 56, so that the lead screw 58 can be connected to the cross plate 59.
[0036] Furthermore, the diameter of the sliding column 56 is smaller than that of the upright column 55. The opposite ends of the sliding column 56 and the upright column 55 are respectively fixed to the opposite walls of the base plate 54 and the mounting plate 53, so that the sliding column 56 can move in or out of the upright column 55. Thus, the sliding column 56 and the upright column 55 can cooperate to form a telescopic column, which can adjust the distance between the base plate 54 and the mounting plate 53. When the height of the telescopic column is extended, the telescopic column can push the infrared alignment instrument 51 out of the top head 2 through the mounting plate 53 for alignment work. Conversely, it will drive the infrared alignment instrument 51 to retract into the top head 2 so that the top head 2 can lift the aircraft through the top socket of the aircraft.
[0037] In addition, the top of the horizontal plate 59 is provided with a threaded hole for the lead screw 58 to pass through it. The lead screw 58 is threaded to the inside of the threaded hole. The lead screw 58 can drive the horizontal plate 59 to move up and down through the threaded hole of the horizontal plate 59, so that the horizontal plate 59 can drive the sliding column 56 to move into or out of the column 55.
[0038] Meanwhile, the top of the horizontal plate 59 has a round hole for two uprights 510 to pass through it. The uprights 510 are slidably connected to the inside of the round hole. The horizontal plate 59 can slide on the outer surface of the two uprights 510 through the two round holes. When the lead screw 58 is threadedly connected to the threaded hole of the horizontal plate 59, the horizontal plate 59 can restrict the lead screw 58 from rotating through the two uprights 510, so that when the lead screw 58 is threadedly connected to the threaded hole of the horizontal plate 59, it can only move up and down.
[0039] It should be noted that the jack 1, the jack head 2, the infrared alignment instrument 51, and the electronic components mentioned in the text are all commonly known in the prior art. Furthermore, the control method of this embodiment is controlled by a controller. All electrical components mentioned in the text are connected to the controller and the power supply. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The provision of the power supply is also commonly known in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.
[0040] The working principle of the above embodiments is as follows:
[0041] In use, the infrared alignment instrument 51 is threadedly connected to the mounting hole of the mounting plate 53 via the mounting rod 52, so that the mounting rod 52 is fixed in the mounting hole of the mounting plate 53. This allows the infrared alignment instrument 51 to be installed and fixed in the mounting plate 53, thereby installing the infrared alignment instrument 51 on the top head 2 of the jack 1. This enables the jack 1 to have an infrared calibration function, allowing maintenance personnel to view the content scanned by the infrared alignment instrument 51 through the display screen of the control terminal. This ensures that the top head 2 of the jack 1 makes precise contact with the aircraft's top socket, improving the support effect of the jack 1 on the aircraft. It can also effectively reduce the wear on the aircraft surface and the wear on the jack 1 itself, ensuring the lifting effect of the aircraft hydraulic jack on the aircraft, and facilitating the disassembly and replacement of the infrared alignment instrument 51.
[0042] Once the top head 2 is aligned with the aircraft's top socket, maintenance personnel control the micro motor 57 via the control terminal. The output of the micro motor 57 drives the lead screw 58 to rotate, allowing the lead screw 58 to connect threadedly with the threaded hole of the horizontal plate 59. Simultaneously, the two uprights 510 restrict the horizontal plate 59, enabling it to move downwards. This allows the horizontal plate 59 to move the sliding column 56 gradually into the upright column 55. The sliding column 56 then moves the mounting plate 53, gradually shortening the distance between the mounting plate 53 and the base plate 54. This allows the mounting plate 53 to move the infrared alignment instrument 51 into the top head 2, preventing the infrared alignment instrument 51 from contacting the aircraft's top socket during the top head 2's lifting process, thus reducing the risk of damage to the infrared alignment instrument 51 due to load.
