Description

Technical Field

[0001] This utility model relates to the field of helicopter maintenance technology, and in particular to a maintenance platform for helicopters. Background Technology

[0002] As a vertical takeoff and landing aircraft, helicopters are characterized by their compact structure, complex systems, and frequent maintenance. To ensure the safety and performance of helicopters during flight, various key components such as the rotor system, engine nacelle, tail rotor mechanism, fuel tank system, and electronic control devices require regular maintenance, inspection, and upkeep. Since most of the key components of helicopters are located at high positions, maintenance work is usually carried out using a maintenance platform.

[0003] A search revealed Chinese Patent Publication No. CN215617880U, which discloses an adjustable helicopter maintenance platform, belonging to the technical field of helicopter maintenance platforms. This adjustable helicopter maintenance platform includes a platform support assembly and a platform fine-tuning assembly. The platform support assembly includes support platform I, support platform II, and support platform III, assembled from bottom to top. The platform fine-tuning assembly includes a base, a fixing component, self-locking casters, and fine-tuning components. The fine-tuning components include paired servo motors and ball screw pairs. Two servo motors are mounted on one end of the upper surface of the base, and two ball screw pairs are respectively connected to their corresponding servo motors. Ball screw nut pairs are rotatably connected to the outer walls of the two ball screw pairs, and all four ball screw nut pairs are fixedly connected to support platform I. In this application, the platform fine-tuning assembly is connected to the bottom of the platform support assembly. This assembly not only allows for rapid fine-tuning of the platform support assembly's position but also increases the contact area between the maintenance platform and the ground.

[0004] In existing technologies, most lack flexible support for maintenance auxiliary tools and equipment. When maintenance personnel need to change tools or pick up parts during the performance of their tasks, they often need to repeatedly go up and down the platform. This frequent up-and-down movement not only increases maintenance time and manpower consumption, but also easily leads to a decrease in work efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a helicopter maintenance platform, which aims to improve the problem that traditional maintenance platforms lack support for tools and equipment, requiring personnel to repeatedly go up and down the platform to retrieve tools, increasing manpower consumption and affecting work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A helicopter maintenance platform includes a maintenance frame. A fixed frame is fixedly connected to the inner wall of the maintenance frame. A motor is fixedly connected to the outer wall of the fixed frame. A sprocket is fixedly mounted on the output end of the motor. A chain is meshed with the teeth of the sprocket. A sliding block is fixedly connected to the outer wall of the chain. A hollow frame is slidably connected to the outer wall of the sliding block. A support plate is fixedly connected to the outer wall of the hollow frame. A tool frame is fixedly connected to the outer wall of the support plate. A guide rail is slidably connected to the inner wall of the tool frame. The outer wall of the guide rail is fixedly connected to the outer wall of the fixed frame. A movable component is provided at the bottom end of the maintenance frame.

[0008] Through the above technical solution: the maintenance frame can provide fixed support for the fixed frame, thereby providing fixed support for the motor. By turning on the motor, the sprocket can be rotated, which in turn drives the chain to slide, which in turn drives the sliding block and the hollow frame to slide. The up and down sliding of the hollow frame drives the support plate to slide, and the sliding of the support plate will cause the tool frame to slide on the outer wall of the guide rail. By allowing the tool frame to slide up and down, maintenance personnel can avoid frequently going up and down the platform to retrieve tools during maintenance, reducing physical exertion and improving work efficiency.

[0009] As a further description of the above technical solution:

[0010] The movable component includes a base plate, the upper surface of which is fixedly connected to the bottom end of the maintenance frame, the lower surface of the fixed frame is fixedly connected to the upper surface of the base plate, and a caster wheel is fixedly connected to the lower surface of the base plate.

[0011] Through the above technical solution, the base plate can support the maintenance frame, the fixed frame, and the casters. The casters can move the base plate, thereby moving the entire maintenance platform.

[0012] As a further description of the above technical solution:

[0013] A support frame is fixedly connected to the outer wall of the base plate, and a hydraulic cylinder is fixedly connected to the outer wall of the support frame.

[0014] Through the above technical solution: the base plate can support the support frame, and the support frame can fix and support the hydraulic cylinder.

[0015] As a further description of the above technical solution:

[0016] The output end of the hydraulic cylinder is fixedly connected to a sliding frame, the inner wall of the sliding frame is slidably connected to a slide rail, and the outer wall of the slide rail is fixedly connected to the inner wall of the support frame.

[0017] Through the above technical solution: when the hydraulic cylinder is activated, the hydraulic cylinder can drive the sliding frame to slide on the outer wall of the slide rail.

[0018] As a further description of the above technical solution:

[0019] The inner wall of the sliding frame is slidably connected to a connecting column, and a sliding groove is provided inside the sliding frame.

[0020] Through the above technical solution: the sliding of the sliding frame will cause the connecting column to slide on the inner wall of the sliding frame, and then slide on the inner wall of the sliding groove.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the connecting column is slidably connected to the inner wall of the sliding groove, and both ends of the connecting column are rotatably connected to fixed plates.

[0023] With the above technical solution, when the connecting column slides from a high position to a low position on the inner wall of the sliding groove, it will also drive the fixing plate to slide downward.

[0024] As a further description of the above technical solution:

[0025] A sliding plate is fixedly connected to the lower surface of the fixed plate, and the outer wall of the sliding plate is set on the inner wall of the support frame.

[0026] Through the above technical solution: the sliding of the fixed plate will cause the sliding plate to slide downward, so that the sliding plate slides out from the inner wall of the support frame, lifting the platform up and making the casters leave the ground, thus improving stability.

[0027] As a further description of the above technical solution:

[0028] A telescopic cylinder is fixedly connected to the upper surface of the sliding plate, and the top end of the telescopic cylinder is fixedly connected to the inner wall of the support frame.

[0029] Through the above technical solution, the sliding plate can support the telescopic cylinder, and the telescopic cylinder can ensure the stability of the sliding plate as it slides downward.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, through the cooperation between the maintenance frame, the fixed frame, the motor, the sprocket, the chain, the sliding block, the hollow frame, the support plate, the tool frame and the guide rail, maintenance personnel can transport tools through the tool frame, avoiding the need for maintenance personnel to go up and down the platform to retrieve tools, reducing manpower consumption and improving work efficiency.

[0032] 2. In this utility model, through the cooperation between the support frame, hydraulic cylinder, sliding frame, slide rail, connecting column, sliding groove, fixed plate, sliding plate and telescopic cylinder, the casters can be lifted off the ground, allowing the tool frame to support the maintenance platform, avoiding the casters from rotating or sliding, and ensuring the safety of personnel and the stability of the operation during maintenance.

[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Reference Figure 1 and Figure 2An embodiment of this utility model provides: a helicopter maintenance platform, including a maintenance frame 1, a fixed frame 2 fixedly connected to the inner wall of the maintenance frame 1, a motor 3 fixedly connected to the outer wall of the fixed frame 2, a sprocket 4 fixedly provided at the output end of the motor 3, a chain 5 meshing with the tooth end of the sprocket 4, a sliding block 6 fixedly connected to the outer wall of the chain 5, a hollow frame 7 slidably connected to the outer wall of the sliding block 6, a support plate 8 fixedly connected to the outer wall of the hollow frame 7, a tool frame 9 fixedly connected to the outer wall of the support plate 8, a guide rail 10 slidably connected to the inner wall of the tool frame 9, a guide rail 10 fixedly connected to the outer wall of the fixed frame 2, and a moving component 11 provided at the bottom end of the maintenance frame 1;

[0041] Specifically, the inspection frame 1 provides fixed support for the fixed frame 2, which in turn provides fixed support for the motor 3. When the motor 3 is turned on, it drives the sprocket 4 to rotate. The rotation of the sprocket 4 causes the chain 5 to slide, and the sliding of the chain 5 causes the sliding block 6 to slide up and down synchronously with the chain 5. The sliding of the sliding block 6 causes the hollow frame 7 to slide up and down. When the sliding block 6 slides from one side to the other, it slides on the inner wall of the hollow frame 7 to adjust its position. At the same time, the up and down sliding of the hollow frame 7 also... The support plate 8 slides, which in turn causes the tool frame 9 to slide up and down on the outer wall of the guide rail 10. The guide rail 10 provides sliding support for the tool frame 9, ensuring its stability. The fixed frame 2 also provides fixed support for the guide rail 10. The tool frame 9 can hold maintenance tools. By sliding the tool frame 9 up and down, tools can be moved from the top to the bottom or vice versa for maintenance personnel to use. This avoids maintenance personnel having to go up and down the platform to retrieve tools, reducing manpower consumption and improving work efficiency.

[0042] Reference Figure 3 The movable component 11 includes a base plate 1101, the upper surface of which is fixedly connected to the bottom end of the maintenance frame 1, the lower surface of the fixed frame 2 is fixedly connected to the upper surface of the base plate 1101, and a caster wheel 1102 is fixedly connected to the lower surface of the base plate 1101.

[0043] Specifically, the base plate 1101 can provide fixed support for the maintenance frame 1 and the fixed frame 2, ensuring the stability of the maintenance frame 1 and the fixed frame 2. The base plate 1101 can also support the casters 1102. When the casters 1102 rotate and move, they will also drive the base plate 1101 to move, thereby driving the entire maintenance platform to move.

[0044] Reference Figure 4A support frame 12 is fixedly connected to the outer wall of the base plate 1101, and a hydraulic cylinder 13 is fixedly connected to the outer wall of the support frame 12; a sliding frame 14 is fixedly connected to the output end of the hydraulic cylinder 13, and a slide rail 15 is slidably connected to the inner wall of the sliding frame 14, and the outer wall of the slide rail 15 is fixedly connected to the inner wall of the support frame 12; a connecting column 16 is slidably connected to the inner wall of the sliding frame 14, and a sliding groove 17 is provided inside the sliding frame 14;

[0045] Specifically, the base plate 1101 can provide fixed support for the support frame 12, and the support frame 12 can also provide fixed support for the hydraulic cylinder 13. When the hydraulic cylinder 13 is activated, the hydraulic cylinder 13 will drive the sliding frame 14 to slide on the outer wall of the slide rail 15. The slide rail 15 can provide sliding support for the sliding frame 14 to ensure the stability of the sliding frame 14. The support frame 12 can also provide fixed support for the slide rail 15. When the sliding frame 14 slides, it will also drive the connecting column 16 to slide on the inner wall of the sliding frame 14 and the sliding groove 17.

[0046] Reference Figure 4 The outer wall of the connecting column 16 is slidably connected to the inner wall of the sliding groove 17, and both ends of the connecting column 16 are rotatably connected to the fixing plate 18; the lower surface of the fixing plate 18 is fixedly connected to the sliding plate 19, and the outer wall of the sliding plate 19 is set on the inner wall of the support frame 12; the upper surface of the sliding plate 19 is fixedly connected to the telescopic cylinder 20, and the top end of the telescopic cylinder 20 is fixedly connected to the inner wall of the support frame 12.

[0047] Specifically, when the sliding frame 14 slides, it also causes the connecting column 16 to slide from the high point to the low point of the inner wall of the sliding groove 17. The downward sliding of the connecting column 16 causes the fixing plates 18 on both sides to move downward synchronously. The movement of the fixing plates 18 also causes the sliding plate 19 to move downward synchronously. When the sliding plate 19 moves downward, it can lift the support frame 12, causing the support frame 12 to move upward. The movement of the support frame 12 will then cause the base plate 1101 to move upward, thereby causing the casters 1102 to move upward and lift off the ground. The entire maintenance platform is now supported by the sliding plate 19 in contact with the ground, no longer relying on the casters 1102 for support. This avoids the casters 1102 from rotating or sliding, ensuring the safety of personnel and the stability of the operation during maintenance. At the same time, when the sliding plate 19 slides downward, it also causes the telescopic cylinder 20 to extend and retract. The telescopic cylinder 20 allows the sliding plate 19 to slide downward in parallel, ensuring the stability of the sliding plate 19.

[0048] Working principle: When using this maintenance platform, first place the maintenance tools inside the tool frame 9, then turn on the motor 3. The motor 3 drives the sprocket 4 to rotate, and the rotation of the sprocket 4 will drive the chain 5 to slide. The sliding of the chain 5 will drive the hollow frame 7 to slide up and down. At the same time, the sliding of the hollow frame 7 will also drive the support plate 8 to slide. The sliding of the support plate 8 will then drive the tool frame 9 to slide up and down on the outer wall of the guide rail 10, sliding the tool frame 9 to the top. This allows maintenance personnel to directly access the tools inside the tool frame 9, avoiding the need for maintenance personnel to go up and down the platform to retrieve tools, reducing manpower consumption and improving work efficiency.

[0049] Then, the hydraulic cylinder 13 is opened, which pushes the sliding frame 14 to slide on the outer wall of the slide rail 15. The sliding of the sliding frame 14 will cause the connecting column 16 to slide downward, and the sliding of the connecting column 16 will also cause the fixing plate 18 to slide downward. At the same time, the sliding of the fixing plate 18 will cause the sliding plate 19 to slide downward. By sliding the sliding plate 19 downward, the entire maintenance platform can be lifted upward, so that the casters 1102 can leave the ground. The tool frame 9 supports the maintenance platform, preventing the casters 1102 from rotating or sliding, and ensuring the safety of personnel and the stability of the operation during maintenance.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
