Description

Technical Field

[0001] The utility model belongs to the technical field of helicopter installation, in particular to an auxiliary installation fixture for helicopter blades. Background Art

[0002] The main rotor blade is an important part of the helicopter lift system and is also the most valuable part of the helicopter. Currently, the installation process is usually done manually, which requires two to three people to work together, which is time-consuming and laborious. Therefore, a helicopter blade auxiliary installation fixture is needed, which can be completed by one person. However, even if the traditional helicopter blade auxiliary installation fixture is operated by one person, it still needs to be manually pushed and loaded, and then the position is adjusted. In addition, the blade itself is very heavy, which is still quite laborious.

[0003] A Chinese patent document (authorization announcement number CN206476128U) discloses a helicopter blade auxiliary installation device, including a blade rack and a blade hanger. The blade rack is composed of two vertical poles and connecting rods fixedly connected to the two vertical poles at both ends. The tops of the two vertical poles are fixedly connected with blade support blocks with U-shaped grooves. The blade hanger includes a suspension rod and a cross bar fixedly connected to the bottom of the suspension rod. The two ends of the cross bar are fixedly connected with blade clamping devices. The beneficial effects of the utility model are as follows: the utility model saves manpower, changes the original three-person cooperation to one person's independent completion, meets the requirements of the production line, eliminates the tedious blade installation angle adjustment work, and greatly improves the helicopter blade installation efficiency. Although it can be operated by one person and improves efficiency, it also requires manual pushing and loading, and then adjusting the position. In addition, the blade itself is very heavy, which is still relatively laborious. Utility Model Content

[0006] Three vertical electric push rods are connected to the bottom end of the assembly plate, and the bottom end of the vertical electric push rods is connected to a brake caster. The side of the fixed part of one of the vertical electric push rods is connected to an L-shaped limiting plate for limiting the helicopter blades. A plurality of auxiliary electric push rods are embedded in the side of the support plate, and the moving part of the auxiliary electric push rods is connected to an adjustment plate for adjusting the position of the helicopter blades.

[0007] As a preferred embodiment, a connecting rod is connected to the side of one of the vertical electric push rods, and an oblique connecting rod is connected between the connecting rod and the other two vertical electric push rods.

[0010] As a preferred embodiment, the inner wall of the support plate is rotatably connected to a plurality of equally spaced sliding rods, a vertical plate is welded to the side of the support plate, and a lifting electric push rod is connected to the side of the vertical plate.

[0011] As a preferred embodiment, the top end of the moving part of the lifting electric push rod is connected to a lifting lug, and the lifting lug is rotatably connected to a conveying wheel via a rotating shaft.

[0012] As a preferred embodiment, a servo motor is connected to the side of the lifting ear, and the output shaft of the servo motor passes through the lifting ear and is connected and fixed to one of the rotating shafts.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The helicopter blade auxiliary installation fixture benefits from the design of the vertical electric push rod, the auxiliary electric push rod and the linear motor. The extension of the vertical electric push rod can adjust the height of the helicopter blade after loading. The extension of the auxiliary electric push rod enables the adjustment plate to adjust the position of the helicopter blade. The linear motor drives the support plate to move, and indirectly drives the helicopter blade to move toward the main helicopter device. Multiple drives save time and effort compared with manual processing.

[0015] Thanks to the design of the slide bar and the conveyor wheel, the slide bar can support the helicopter blades and ensure that the helicopter blades are moved during subsequent pushing. The servo motor drives the conveyor wheel to rotate and assists the helicopter blades to move toward the limit plate, which is more labor-saving than pushing.

[0016] Thanks to the design of the pressure plate and the adjustment electric push rod, the extension of the electric push rod is adjusted so that the pressure plate cooperates with the support plate to fix the helicopter blades;

[0017] The helicopter blade auxiliary installation fixture can assist the helicopter blade in adjustment and displacement, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS
