Problems solved by technology
Since most of the single-cylinder pull-up power units have their own pyrotechnics, there is a certain degree of danger, so there must be no operation that causes explosives to explode during the operation.
The inner spring of the pull rod of the power unit is compressed to produce axial elastic force, and the use of non-standard tools and manpower itself has unstable factors. If there is hand slipping, tool breakage, or force direction deviation, it may cause damage to the power unit. Serious damage to personal property

The invention relates to an axial tension device capable of providing the guiding orientation function. The axial tension device comprises a tension device structure and a hand stress application rod. The tension device structure comprises a handle. The handle is connected with a lifting guide pillar in a threaded connection mode. One end of the lifting guide pillar is connected with a brake block through a cover plate fixing position. The two ends of the hand stress application rod are connected with bulbs in a threaded connection mode, and the hand stress application rod is connected with the lifting guide pillar through a lifting guide pillar center through hole. In the actual connecting process, the brake block makes contact with bosses on the tail portion of an aircraft and is fixedly connected with the bosses through a connector located between the bosses. The handle is connected with the tail portion of a power device and used for providing tensile force. The displacement distance can be generated while the lifting guide pillar is rotated, so that the power device is pulled slowly through handle acting force and brake block counter-acting force, and the effect that the force application direction is in an axial linear type is guaranteed. Assembling danger in the connecting process can be reduced, damage to the power device in the personnel operating process is avoided, and series harm to personnel and properties can also be avoided.
Description
technical field [0001] The invention relates to a tension device, in particular to an axial tension device capable of providing guidance and positioning. Background technique [0002] The applicable power device of the present invention is a single-cylinder lifting type power device, which is one of the components of the box body module. Its position is located in the middle of the guide rail of the aircraft box, which can fix the aircraft during storage and transportation and prevent the axial movement of the aircraft; when the system is running, it can ensure that the aircraft ejects from the box according to the predetermined track, and gives the initial track to the aircraft. In the process of connecting the power unit to the aircraft, due to the single-cylinder pull-up design requirements, an external force needs to be applied during the connection process to connect the lifting hook of the power unit to the tail interface of the aircraft, and finally complete the assem...
