Description

Technical Field

[0001] This utility model relates to the field of ground support equipment technology, specifically to a civil aircraft tire changing simulation training device. Background Technology

[0002] In civil aviation ground support operations, changing aircraft tires is a routine task. Since different aircraft have different tire models, ground crew need to be familiar with changing tires for various models, requiring extensive training. Current training methods primarily use virtual and hands-on exercises. While virtual training can reduce equipment wear and tear costs, it struggles to replicate the realism of actual training, lacking simulation of the mechanical feedback during tire removal and installation (such as the tactile perception of bolt preload torque and the resistance feedback of hydraulic tire changers), making it difficult for operators to develop genuine muscle memory. Hands-on training relies on real aircraft tires, but frequent operator errors (such as overuse of torque wrenches and wheel impact damage) increase the cost per training session. Furthermore, limitations imposed by spare parts inventory and aircraft scheduling make it difficult to achieve high-frequency, multi-aircraft-type comprehensive training. Utility Model Content

[0003] To address the aforementioned issues, the purpose of this invention is to provide a civil aircraft tire replacement simulation training device. This device has a stable and reliable structure, significantly improving operational realism and safety while reducing training costs. It solves the pain points of traditional virtual training lacking tactile feedback and practical training relying on aircraft materials, providing ground crew with an efficient, economical, and realistic training platform.

[0004] The objective of this utility model is achieved through the following technical solution. A civil aircraft tire changing simulation training device includes a base plate, a fixed column, a movable column, and a mounting shaft; the base plate is placed flat on the ground; the fixed column is vertically fixed to the rear side of the base plate; the rear end of the movable column is hinged to the fixed column, while its front end extends above the middle of the base plate; the mounting shaft is horizontally installed on the side wall of the front end of the movable column, and a flange for installing tires is fixed on the mounting shaft.

[0005] Furthermore, a guide plate is fixed at the bottom of the rear end of the movable column, and a guide groove is fixed at the front side of the fixed column. The guide plate is slidably disposed in the guide groove.

[0006] Furthermore, two arc-shaped reinforcing ribs are installed on the base plate, with the concave surfaces of the two reinforcing ribs facing outwards and symmetrical to each other.

[0007] Furthermore, two reinforcing ribs are arranged in a figure-eight shape at the bottom of the base plate. One end of the reinforcing rib is fixed to the front side wall of the fixed column, and the other end extends to the corner of the front end of the base plate on the same side. The two reinforcing ribs are located on both sides directly below the movable column.

[0008] Furthermore, a top rod is vertically fixed at the bottom of the front end of the mounting shaft, and the top rod is located directly above the area between the two reinforcing ribs.

[0009] The beneficial effects of this utility model are as follows: (1) The structure is stable and reliable. The movable column is connected to the fixed column by hinge, and the guide groove constrains the motion trajectory, which not only ensures the degree of freedom of operation, but also prevents the device from shifting or tipping over due to misoperation.

[0010] (2) Low cost and high adaptability: modular flanges and mounting shafts allow for the adaptation of various tires by changing different models of flanges, eliminating the need to rely on real aircraft parts inventory and reducing training costs for multiple aircraft types.

[0011] (3) Independent simulation devices replace real aircraft, avoiding the damage to expensive aircraft materials caused by novice misoperation (such as torque over-limit, wheel hub impact), and significantly reducing the cost of a single training session.

[0012] (4) The dual mounting shafts and top rods provide multi-dimensional support to ensure that the training process is stable and controllable.

[0013] (5) Training efficiency is improved, and it is not restricted by aircraft scheduling. It can carry out disassembly and assembly practice on multiple aircraft types and in multiple scenarios at any time, thereby improving training coverage and proficiency.

[0014] (6) Close to the real scene, the flange fixing method and other details are designed to restore the real wheel structure, shortening the adaptation period from virtual training to actual operation. Attached Figure Description

It should be noted that the terms "comprising," "including," or any other variations are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Example 1

[0023] like Figure 1-3 As shown in the figure, this embodiment discloses a civil aircraft tire changing simulation training device, including a base plate 1, a fixed column 2, a movable column 3, a mounting shaft 4, and a guide mechanism.

[0024] The base plate 1 is placed flat on the ground, serving as the basic support platform for the device. It bears the weight of all components and the dynamic load during operation, ensuring the overall stability of the device and providing a rigid installation benchmark for components such as the fixed column 2 and the movable column 3, thus preventing the device from tipping over due to force displacement during training.

[0025] The fixed column 2 is vertically fixed to the middle of the rear side of the base plate 1. The fixed column 2 serves as the hinge base of the movable column 3, supporting the rotational movement of the movable column 3 through the hinge point (hinge 5), providing rigid constraint in the vertical direction, and cooperating with the guide groove 7 to limit the swing range of the movable column 3 and prevent uncontrolled movement.

[0026] The rear end of the movable column 3 is hinged to the fixed column 2 via a hinge 5, while the front end of the movable column 3 extends above the middle of the bottom plate 1. The movable column 3 is used to simulate the lifting and lowering action of the tire 11 during disassembly and assembly. The hinge 5 enables the degree of freedom of operation, transmits the torque applied by the operator, and drives the mounting shaft 4 and the tire 11 to complete the disassembly and assembly training action.

[0027] The mounting shaft 4 is horizontally mounted on the side wall at the front end of the movable column 3. A flange 10 for mounting the tire is detachably fixed to the mounting shaft 4. There are two mounting shafts 4, each horizontally fixed to one side of the front end. The mounting shaft 4 serves as the support axis for the tire 11, transmitting rotational force and torque, and is compatible with different models of flange 10. The flange 10 adopts a modular design, allowing for the replacement of different specifications to match tires 11 of various models, reducing training costs. A top rod 9 is vertically fixed at the bottom of the front end of the mounting shaft 4, and the top rod 9 is used to contact the top head of the hydraulic lifting device.

[0028] The guiding mechanism includes a guide plate 6 and a guide groove 7. The guide plate 6 is fixed to the bottom of the rear end of the movable column 3. The guide groove 7 is fixed to the front side of the fixed column 2. The guide plate 6 is slidably disposed within the guide groove 7. The guide groove 7 has a limiting protection function, restricting the movement range of the movable column 3 and preventing personnel or equipment damage due to uncontrolled swinging during the disassembly and assembly of the tire 11, thus improving operational safety. The guide groove 7 consists of two plates vertically fixed to the front side of the fixed column 2 and located on both sides of the guide plate 6. The guiding mechanism plays a limiting protection role, restricting the sliding trajectory of the guide plate 6 through the vertical plates on both sides of the guide groove 7, preventing excessive swinging of the movable column 3 from causing equipment or personnel damage.

[0029] Working principle:

[0030] like Figure 2 As shown, before practicing disassembling and assembling tire 22, flanges 10 matching the model of tire 11 to be practiced are installed on the two mounting shafts 4 respectively. Then, tire 11 is installed on the flanges 10 of the two mounting shafts 4 respectively (the bottom of tire 11 is in contact with the base plate 1).

[0031] When practicing tire 11 removal and replacement, place the hydraulic jacking device (such as a jack) on the base plate 1 below the front end of the movable column 3, with its top end facing the jacking rod 9. Activate the hydraulic jacking device; the top end of the device moves upward and contacts the bottom of the jacking rod 9, lifting the movable column 3. The movable column 3 rises around the hinge 5, causing the mounting shaft 4 and the tire 11 on it to rise. Once the bottom of the tire 11 has moved upward and away from the base plate 1, tire 11 removal and replacement training can begin. At the end of the training, the top end 9 of the hydraulic jacking device moves downward and disengages from the jacking rod 9, and the bottom of the tire 11 falls back onto the base plate 1, completing the training. Example 2

[0032] The difference between this embodiment and Embodiment 1 is that two arc-shaped reinforcing ribs 8 are installed on the base plate 1. The concave surfaces of the two reinforcing ribs 8 face outward and are symmetrical to each other. The two reinforcing ribs 8 are arranged in a V-shape at the bottom of the base plate 1. One end of the reinforcing rib 8 is fixed to the front side wall of the fixed column 2, and the other end extends to the corner of the front end of the base plate 1 on the same side. The two reinforcing ribs 8 are located on both sides directly below the movable column 3, and the top rod 9 is located directly above the area between the two reinforcing ribs. The two arc-shaped reinforcing ribs 8 are symmetrically distributed, which significantly improves the compressive and bending resistance of the base plate 1, avoids deformation or damage caused by uneven force during frequent training, extends the life of the device, and also has an anti-displacement effect. The fixed column 3 and the extended end of the front end of the base plate 1 form a triangular support to prevent structural loosening during frequent training.

[0033] Other aspects of this utility model that are not detailed herein are all conventional techniques known to those skilled in the art.

[0034] It should be noted that the terms “comprising,” “including,” or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0035] The scope of protection of this utility model is not limited to the technical solutions disclosed in the specific embodiments. Any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the technical essence of this utility model shall fall within the scope of protection of this utility model.
