[0020] Example

[0021] like Figure 1-3 As shown, the present invention proposes a quick-assembly and disassembly type blade movable bracket, which includes a main bracket module 1, a connecting module 2, a moving module 3 and an auxiliary module 4. It adopts a modular design and a connection form that allows for quick assembly and disassembly, which greatly reduces the transportation volume and improves the flexibility of product use. When the main bracket module 1, connecting module 2, moving module 3 and auxiliary module 4 are in a fully assembled mode, the blade movable bracket can simultaneously place the main blade and tail blade of each model of aircraft on one stand, and has a short-distance movement function.

[0022] The main support module 1 includes three sets of main blade support block assemblies 11, namely a front support, a middle support, and a rear support. Each main blade support block assembly 11 includes a crossbeam 111. Above each crossbeam 111 are two sets of single-sided columns 112. The mounting ends of the two sets of single-sided columns 112 are installed corresponding to the top of the crossbeam 111. The two sets of single-sided columns 112 are positioned between the crossbeam 111 and the crossbeam 111. Multiple sets of double-sided columns 113 are installed on the upper part. The mounting end of each set of double-sided columns 113 is installed corresponding to the upper part of the crossbeam 111. The mounting end of each set of double-sided columns 113 is fixedly connected to the upper part of the crossbeam 111. Flexible slings 114 are provided between two sets of double-sided columns 113 that are close to each other, and between the single-sided column 112 and the double-sided columns 113. The flexible slings 114 can be adapted to the blade shape of different models. Each set of single-sided columns 112 and double-sided columns 113 is equipped with a... There is a sling seat 116, and the mounting ends of the sling seat 116 are fixedly connected to the top of the single-sided column 112 and the double-sided column 113 respectively. The sling seat 116 on the single-sided column 112 is set in a single-sided form. One end of the flexible sling 114 is installed corresponding to the sling seat 116. One end of each set of flexible slings 114 is connected to an adjusting buckle 115 on the crossbeam 111. The mounting end of the adjusting buckle 115 is fixedly connected to the top of the crossbeam 111. The other end of the flexible sling 114 is connected to the adjusting buckle 115. Correspondingly, the setting of the adjusting buckle 115 can be adjusted by the tension of the flexible sling 114 through the sling seat 116, so as to better adapt to different blades. The front bracket also includes the front tail rotor support block, the middle bracket also includes the middle tail rotor column and the middle tail rotor support block, and the rear bracket also includes the rear tail rotor column. The three sets of main blade support block assemblies 11 can be placed on a flat ground according to the different models used, in a simple mode, to complete the support function of the main blade and tail rotor.

[0023] The connecting module 2 includes a front right connecting rod 21 and a front left connecting rod 22 located between two sets of main blade support block assemblies 11. Each of the two sets of crossbeams 111 in the front bracket and the middle bracket has a connection port 1 on one side close to each other. The two ends of the front right connecting rod 21 and the front left connecting rod 22 are respectively installed corresponding to the connection ports 1 between the two sets of crossbeams 111 in the front bracket and the middle bracket. A rear right connecting rod 23 and a rear left connecting rod 24 are located at the rear position between the two sets of main blade support block assemblies 11. Each of the two sets of crossbeams 111 in the middle bracket and the rear bracket has a connection port 2 on one side close to each other. The two ends of the rear right connecting rod 23 and the rear left connecting rod 24 are respectively installed corresponding to the connection ports 111 between the two sets of main blade support block assemblies 11. The two sets of crossbeams 111 in the middle bracket and the rear bracket are connected at the corresponding ports. Both the first and second connecting ports are set in the form of female buckles. The two ends of the front right connecting rod 21, the front left connecting rod 22, the rear right connecting rod 23 and the rear left connecting rod 24 are set in the form of male buckles. The front right connecting rod 21 and the front left connecting rod 22 are snapped into the female buckles on the front bracket and the middle bracket, and the rear right connecting rod 23 and the rear left connecting rod 24 are snapped into the female buckles on the middle bracket and the rear bracket. This enables quick disassembly and assembly between the connecting module 2 and the main bracket module 1. The quick assembly and disassembly connection reduces transportation difficulty and improves the flexibility of product use.

[0024] The moving module 3 includes lockable casters 31 located below both ends of each set of crossbeams 111. Each set of crossbeams 111 has a wheel mounting seat below both ends. The mounting ends of the lockable casters 31 are correspondingly installed with the wheel mounting seats, and are fixedly assembled with the wheel mounting seats using quick-release pins. Each set of crossbeams 111 has a traction rope 32 at both ends, and each set of crossbeams 111 has a rope placement post 5 on one side. The mounting end of the rope placement post 5 is fixedly connected to one side of the crossbeam 111. One end of each of the two sets of traction ropes 32 on the same side is installed corresponding to one end of the crossbeam 111. Both ends of the crossbeam 111 are provided with rope holes. One end of the traction rope 32 is fixedly connected to the rope hole. The other end of each of the two sets of traction ropes 32 on the same side is fitted around the outer ring of the rope placement column 5. The rope placement column 5 allows the traction rope 32 to be placed easily when not in use. The traction rope 32 can cooperate with the lockable caster wheel 31 to move the device, thereby enabling the transfer of the blade.

[0025] The auxiliary module 4 includes a front tail rotor movable support block 41 located on the front right connecting rod 21 and a rear tail rotor movable support block 42 located on the rear right connecting rod 23. Both the front right connecting rod 21 and the rear right connecting rod 23 have multiple sets of adjusting pin holes. The mounting end of the front tail rotor movable support block 41 is installed corresponding to the front right connecting rod 21, and the mounting end of the rear tail rotor movable support block 42 is installed corresponding to the rear right connecting rod 23. Both the rear tail rotor movable support blocks 42 and 43 are adjustable, so as to adapt to different helicopter rotor blade placement operations.

[0026] In this embodiment, the movable blade bracket adapts to the support requirements of various types of main blades and tail blades. It adopts a flexible sling 114 as the support structure and a snap fastener as the connecting part for the front bracket, middle bracket and rear bracket. It adopts a basic configuration in which the main function and auxiliary function can be separated.

[0027] When the main bracket module 1, connecting module 2, moving module 3 and auxiliary module 4 of this device are in a fully assembled mode, the blade movable bracket can simultaneously place the main blade and tail blade of each model of aircraft, and has a short-distance moving function.

[0028] When the device is arranged in a simplified manner on a flat surface according to the different models of the aircraft, the front bracket, middle bracket, rear bracket, front tail rotor support block, and rear tail rotor movable support block 42 can complete the support function of the main rotor blade and tail rotor.

[0029] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
