[0001] This utility model relates to the field of landing gear testing technology, specifically a landing gear testing device. Background Technology

[0002] Landing gear is a critical component of an aircraft, needing to withstand enormous loads (including vertical impact forces, horizontal friction forces, and lateral wind loads) during takeoff, landing, and taxiing. To ensure its reliability, it must be tested using testing equipment. However, the existing landing gear testing equipment is not convenient for quickly connecting and installing the landing gear to be tested during its use, which makes it difficult for operators to separate and install the landing gear after use, thus increasing the downtime of the equipment. Therefore, in order to address the above problems, there is an urgent need to innovate the design based on the existing landing gear testing device. Utility Model Content

[0003] The purpose of this utility model is to provide a landing gear testing device to solve the problem mentioned in the background art that it is inconvenient to quickly connect and install the landing gear to be tested during the use of the device, which makes it difficult for operators to separate and install the landing gear after use, thus increasing the downtime of the device.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a landing gear testing device, comprising: a base, and a support frame disposed on the left side of the base, a guide frame disposed on the right side of the support frame, and a mounting block connected to the middle of the guide frame; Also includes: A reinforcing frame is installed on the left side of the support frame, and a limit rod passes through the middle of the reinforcing frame. A guide rod is connected to the lower end of the reinforcing frame. A first drive motor is provided at the lower end of the support frame, and a first drive rod is connected to the upper side of the first drive motor. A support block is connected to the upper side of the first drive rod, and a first guide strip is provided on the outer side of the support block. A hydraulic rod is installed inside the guide frame, and a second guide bar is provided on the outside of the hydraulic rod. A dual-drive limiting component is provided inside the mounting block, and a sensor is installed at the lower end of the mounting block. The lower end of the sensor is connected to a support plate, and a first guide plate is provided on the outside of the support plate. A second guide plate is provided on the outside of the first guide plate. A simulated fan is provided on the rear side of the base.

[0005] In one possible implementation, the reinforcing frame is engaged with the guide rod, and the limiting rod is threadedly connected to both the reinforcing frame and the support frame.

[0006] In one possible implementation, the first drive rod is threadedly connected to the support block, and the support block is slidably connected to the first guide bar.

[0007] In one possible implementation, the first guide bar has a "T" shaped cross-section and is symmetrically arranged about the central axis of the support frame.

[0008] In one possible implementation, the mounting block is slidably connected to the second guide strip, and the upper longitudinal section of the mounting block has an "I" shaped structure.

[0009] In one possible implementation, both the second guide plate and the first guide plate are slidably connected to the mounting block, and the first guide plate is symmetrically arranged about the central axis of the support plate.

[0010] In one possible implementation, the dual-drive limiting assembly includes a second drive motor installed inside the mounting block, with a first drive disc connected to the front end of the second drive motor, a second drive rod connected to the front end of the first drive disc, a second drive disc disposed in the middle of the second drive rod, a limiting frame connected to the outer side of the second drive disc, a guide block connected to the outer side of the limiting frame, and a limiting plate disposed at the lower end of the limiting frame. The first drive disk and the second drive disk are engaged with each other, and the second drive rod and the second drive disk are rotatably connected to the mounting block.

[0011] In one possible implementation, the second drive rod is threadedly connected to the limit frame, and the threads at the left and right ends of the second drive rod are opposite to each other, and the limit frame is slidably connected to the guide block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This landing gear testing device facilitates the rapid connection and installation of the landing gear to be tested during use, making it easy for operators to separate and install the completed landing gear, reducing downtime. Furthermore, the device incorporates multi-directional drive test results, enabling multi-dimensional force testing of the landing gear to be tested, providing more diverse test data and resulting in better performance. Specifically, as shown below: 1. The second drive motor, in conjunction with the first drive disc, drives the second drive rod and the second drive disc to rotate inside the mounting block. This causes the second drive rod to move the limit frame and the limit plate inward along the guide block to constrain and limit the landing gear placed at the lower end of the support plate. The landing gear is initially limited and locked by lateral clamping, avoiding the need for operators to lift the landing gear for a long time during the process of fixing the landing gear. 2. The first drive motor, in conjunction with the first drive rod, pushes the support block to move up and down along the first guide bar inside the support frame, causing the support block to drive the guide frame and mounting block connected to its right side, as well as the landing gear, to move from the upper side of the base to the lower side and contact the ground. At this time, the support plate, in conjunction with the first guide plate and the second guide plate, uses the compression sensor to perform real-time detection, thereby completing the vertical impact force detection of the landing gear. 3. By using a hydraulic rod in conjunction with the second guide bar, the mounting block is pushed to move left and right inside the guide frame, so that the mounting block drives the landing gear set at its lower end inside the device to simulate the actual working conditions of the landing gear during use, ensuring that the test results of the device are effective and convincing, and improving the use effect of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 This utility model provides a technical solution: a landing gear testing device, including a base 1, a guide rod 2, a support frame 3, a reinforcing frame 4, a limiting rod 5, a first drive motor 6, a first drive rod 7, a support block 8, a first guide bar 9, a guide frame 10, a hydraulic rod 11, a mounting block 12, a second guide bar 13, a second drive motor 14, a first drive disc 15, a second drive rod 16, a second drive disc 17, a limiting frame 18, a guide block 19, a limiting plate 20, a sensor 21, a support plate 22, a first guide plate 23, a second guide plate 24, and a simulated fan 25.

[0017] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, during the use of the device, by installing the landing gear on the lower side of the support plate 22, the second drive motor 14 installed inside the mounting block 12 is activated, causing the second drive motor 14 to drive the first drive disc 15 connected to its front end to rotate inside the mounting block 12. Due to the meshing connection structure between the first drive disc 15 and the second drive disc 17, the first drive disc 15 can effectively push the second drive rod 16 and the second drive disc 17 to rotate inside the mounting block 12 during the rotation process. At this time, due to the threaded connection structure between the second drive rod 16 and the limit frame 18... This allows the second drive rod 16 to effectively push the limiting frame 18 inward during rotation. Due to the opposing threaded structures at both ends of the second drive rod 16, it can synchronously push the limiting frame 18 inward relative movement during rotation. At this time, because of the sliding connection between the guide block 19 and the limiting frame 18, the limiting frame 18 is guided and limited by the guide block 19 during inward displacement, preventing positional displacement. The inward displacement of the limiting frame 18 then drives its lower... The side-connected limiting plate 20 moves inward to laterally limit the landing gear placed under the support plate 22, thus completing the initial limiting work for the landing gear. This allows the operator to fix the landing gear in series to the lower end of the support plate 22 with bolts, and to initially limit and lock the landing gear by lateral clamping. This avoids the need for the operator to lift the landing gear for a long time during the fixing process, reducing the operator's labor intensity. At the same time, after completing the limiting work for the landing gear, the reinforcement frame 4 is installed on the left side of the support frame 3. Due to the sliding between the reinforcement frame 4 and the guide rod 2, The connection structure allows the operator to effectively refer to the guide rod 2 to stably place the reinforcement frame 4 on the left side of the support frame 3 during the installation of the reinforcement frame 4. At this time, the limiting rod 5 that runs through the middle of the reinforcement frame 4 is rotated. Due to the threaded connection structure between the limiting rod 5 and the reinforcement frame 4 and the support frame 3, the limiting rod 5 can effectively fix the reinforcement frame 4 to one side of the support frame 3 during the rotation process. At this time, due to the triangular structure of the reinforcement frame 4, the support frame 3 can be effectively reinforced by the reinforcement frame 4 when it bends and breaks due to pressure, thus improving the stability of the device.

[0018] Specifically, such as Figure 3 , Figure 4 and Figure 6As shown, during the use of the device, by activating the first drive motor 6 installed inside the support frame 3, the first drive motor 6 drives the first drive rod 7 connected to its upper side to rotate inside the support frame 3. Due to the threaded connection structure between the first drive rod 7 and the support block 8, the rapidly rotating first drive rod 7 can effectively push the support block 8 to move up and down inside the support frame 3. At this time, due to the sliding connection structure between the first guide strip 9 and the support block 8, the support block 8 is guided and limited by the first guide strip 9 during the up and down movement, preventing the support block 8 from shifting position during the up and down movement. At this time, the support block 8 moving downwards, together with the guide frame 10, pushes the mounting block 12 and the landing gear to move downwards and contact the ground. At this time, the landing gear pushes the support plate 22 to move upwards. Due to the sliding connection structure between the first guide plate 23 and the second guide plate 24 and the mounting block 12, the support plate 22 is guided by the first guide plate 23 during the upward movement. 3. The second guide plate 24 guides and limits the movement of the support plate 22 to prevent it from shifting position during movement. At this time, the sensor 21 on the upper side of the support plate 22 detects the pressure generated by the movement of the support plate 22 in real time. Simultaneously, the simulated fan 25 on the rear side of the base 1 is activated, which generates a strong lateral wind to conduct a lateral pressure test on the landing gear. At this time, the hydraulic rod 11 inside the guide frame 10 is activated, which pushes the mounting block 12 connected to its left side to move left and right inside the guide frame 10. Due to the sliding connection structure between the second guide bar 13 and the mounting block 12, the mounting block 12 is guided and limited by the second guide bar 13 during left and right movement, preventing it from shifting position during movement. At this time, the mounting block 12 drives the landing gear at its lower end to simulate the actual working conditions of the landing gear during use inside the device, ensuring that the test results of the device are convincing and improving the effectiveness of the device.
