Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] As mentioned in the background of the application, it is found through research that the brake force of the existing throttle lever in the off-machine state is different from the brake force index when it is installed to the on-machine engine control system, because the connection of the steel cable on the machine causes the change of the product state, and the brake force will also change accordingly, causing the on-machine brake force of the throttle lever after completing the off-machine brake force adjustment work to not meet the requirements, thereby causing rework, bringing about the work of giving way and on-machine adjustment, and having certain defects.

[0022] In order to solve the above defects, the application discloses an on-machine installation state simulation device for an aircraft throttle lever, which can more realistically simulate the on-machine installation state of the throttle lever, thereby reducing the difference.

[0023] The scheme of the application will be described in detail below in combination with the drawings on how to solve the above technical problems.

[0024] Please refer to Figs. 1-3 In the embodiment of the application, an on-machine installation state simulation device for an aircraft throttle lever comprises a table type support frame 1 and a throttle lever mounting frame 2 fixed on one side of the top end surface of the table type support frame 1, wherein the other side of the top end surface of the table type support frame 1 is detachably connected with a pulley assembly 3. Through the table type support frame 1, the throttle lever mounting frame 2 and the pulley assembly 3, the on-machine installation state of the throttle lever can be more realistically simulated, thereby reducing the difference.

[0025] In this embodiment, a mounting hole is formed in the top end surface of the throttle lever mounting frame 2, and the throttle lever mounting frame 2 is detachably connected with the external throttle lever through a hexagonal bolt 6 implanted in the mounting hole. This setting can quickly detach the throttle lever as needed.

[0026] In this embodiment, the top end surface of the table type support frame 1 is provided with a sliding rail, the pulley assembly 3 is arranged on the sliding rail and can be adjusted in position, and is fixed on the sliding rail through a T-shaped bolt 4 and a butterfly nut 5. The device uses the T-shaped bolt 4 and the butterfly nut 5, which can complete the quick assembly and disassembly of the corresponding connecting piece.

[0027] In this embodiment, it also includes a process steel cable 7, which passes through the pulley assembly 3, and the two ends of the process steel cable 7 are connected with the steel cables of the throttle lever fixed on the throttle lever mounting frame 2. This setting can adjust the distance between the throttle lever and the pulley assembly 3 to preliminarily adjust the tension of the steel cable after connection.

[0028] In this embodiment, a tension sleeve 8 is arranged at the connection between the process steel cable 7 and the steel cable of the throttle lever, and the tension of the steel cable loop of the throttle lever is adjusted through the tension sleeve 8 to complete the simulation of the on-machine installation state of the throttle lever.

[0029] In the embodiment, the bottom end surface of the table type support frame 1 is provided with a bottom mounting interface, and the table type support frame 1 is mounted to an external vice through the bottom mounting interface. The vice is a general tool, and the interface designed by the table type support frame 1 can be connected with the vice, and has universality.

[0030] The working principle of the utility model is: the table type support frame 1 is mounted to the vice through the bottom mounting interface, then the throttle lever is mounted to the throttle lever mounting frame 2, and the hexagonal bolt 6 is used to fix the throttle lever and the throttle lever mounting frame 2 through the four mounting holes of the throttle lever and the throttle lever mounting frame 2. The process steel cable 7 is passed through the pulley assembly 3, and the steel cable on the throttle lever is connected with the process steel cable 7 using the loose sleeve 8; the position of the pulley assembly 3 is adjusted by adjusting the T-shaped bolt 4 and the butterfly nut 5, so that the initial tension is generated on the loop of the throttle lever steel cable and the process steel cable 7, and then the tension of the steel cable loop is adjusted by the loose sleeve 8. In summary, the application forms a loop through the throttle lever mounting frame 2, the pulley assembly 3, the process steel cable 7 and the loose sleeve 8, simulates the on-machine installation state of the throttle lever, and uses the on-machine installation state simulation device to simulate the on-machine installation state of the throttle lever.
