Problems solved by technology

[0003] 1. The preset ground anchor rings on the ground of the test site need to be constructed in advance, and the distance between the mooring cables of different airships is different.
[0004] 2. During the airship inflation process, due to the huge size of the airship capsule, it is necessary to simultaneously adjust the length of the tethered cables on both sides of the airship capsule while inflating to ensure the smooth deployment of the capsule skin. However, at present, it is manually adjusted by manpower. In side wind on the ground, the pulling force of the mooring cable on the windward side can reach 15000N in an instant, and the safety of manual adjustment is poor. Once the mooring cable is adjusted out of sync, it is very easy to cause safety accidents such as rollover and rollover of the airship capsule
[0005] 3. There are many mooring cables involved in the attitude balance adjustment and buoyancy measurement process, and the synchronization requirements are high. However, the existing adjustment method requires many support personnel, cumbersome operation steps, and long time-consuming during the entire process, which reduces the test performance. Efficiency, increased test process risk

Embodiment 1

[0040] Such as Figure 1-Figure 3As shown, a cable retracting device includes a structural frame 10, a winch part 20, a cable guiding and tension testing part 30, and a control part 40. The winch part 20 is arranged obliquely on the structural frame 10, and the cable is also arranged on the structural frame 10. The guiding and tension testing part 30 and the control part 40, the winch part 20 and the cable guiding and tension testing part 30 are electrically connected to the control part 40, the output end of the winch part 20 is wound around the beginning of the winch rope 50, and the end of the winch rope 50 passes through The cable guiding and tension testing part 30 can reduce the impact of the excess friction force generated on the measurement accuracy of the tension value during the retraction process of the winch rope 50 by tilting the winch part 20 on the structural frame 10, while the winch part 20, the cable The cooperation of the guiding and tension testing part 30 ...

Embodiment 2

[0055] Such as Figure 4-Figure 8 As shown, the difference from Embodiment 1 is that a temporary tethering device for a stratospheric airship using a cable retracting device includes a cable retracting device and a mobile lifting chassis 70, and the cable retracting device is fixed on the mobile lifting chassis 70 Above all, through the cooperation of the cable retractable device and the mobile lifting chassis 70, the tethering equipment is simple and practical, and there is no need to construct ground anchors in advance. It is convenient and quick to lay out, and relies on its own weight as a temporary tethering point on the ground for mooring cables, so that during the ground assembly process of the stratospheric airship, the posture balance adjustment of the airship capsule can be realized by the retracting operation of the cable retracting device, which simplifies The operation process, and the tethering equipment can be flexibly arranged, requiring fewer operators and str...

Embodiment 3

[0066] Such as Figure 9 As shown, the difference from Embodiment 1 is that a temporary tethering device for a stratospheric airship using a cable retracting device includes a cable retracting device and a truss 80, and the cable retracting device is fixed on the truss 80. By retracting the cable The releasing device is arranged on the truss 80, so that the cable retracting device can be applied to the layout occasion of the truss 80 when the stratospheric airship is assembled, and the applicability of the cable retracting device is improved.

[0067] Using the cable retracting device provided by the present invention and the temporary tethering equipment for stratospheric airships using it is simple and practical, can ensure the reliable retraction and deployment of cables, and can realize the flexible deployment of temporary tethering equipment, and at the same time requires fewer operators , The operation process is simple and the synchronization is strong.

Abstract

The invention provides a cable retracting and releasing device and a stratospheric airship temporary tether device using the same, A cable retracting and releasing device comprises a structural frame,winch part, a cable guide and tension test section and a control section, A capstan portion is obliquely arranged on that structural frame, A cable guide and tension testing part and a control part are also arranged on the structural frame, A control part is electrically connected with the winch part and the cable guide and tension test part, The output end of the winch part winds around the beginning end of the winch rope, and the end of the winch rope passes through the rope guide and tension test part. The stratospheric airship temporary tether equipment -using the rope retractor comprisesa rope retractor and a movable lifting chassis, and the rope retractor is fixed on the movable lifting chassis. The invention adopts the device, which is simple and practical, can ensure the reliableretraction and release of the cable, can realize the flexible layout of the temporary tether device, requires few operators, and has simple operation flow and strong synchronization.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for ground assembly of a stratospheric airship, in particular to a cable retracting device and a temporary tethering device for a stratospheric airship using the same. Background technique [0002] As an important representative of modern airships, stratospheric airships can stay in the air for a long time, hover at fixed points and be reused. Stratospheric airships have a high lift-off altitude (generally fly in the stratosphere area near the bottom of the space at 18-23km), and do not need ground mooring cables after lift-off. They mainly rely on buoyant gas to provide static lift, and rely on the propulsion system and control system to achieve Flight control, in order to ensure the flight safety of the airship and the height of lift-off, after the airship capsule is inflated and assembled, it is necessary to adjust the attitude balance and buoyancy measurement of the airship accordi...
