Problems solved by technology

When the existing mooring rope retracting device winds the cable, the cable will be subject to a large lateral pressure under load, and the outer protective foreskin of the mooring rope will wear out quickly after repeated retraction, thereby reducing the service life of the cable, and even Cause the cable to fail and endanger the safety of the entire system
In addition, the cables slip on the retractable equipment and become entangled with each other, which will endanger the safety of the system

Embodiment 1

[0037] Such as Figure 5 As shown, a mooring rope retracting device in this embodiment is installed on the anchor car 6 connected to the bottom plate, and can directly obtain the hydraulic pressure source from the engineering vehicle to realize power transmission. And the anchoring vehicle 6 is movable, adapting to the adjustment of the position change of the floating platform. In this embodiment, the cable 7 is wound on the traction wheel through multiple turns in a single layer, and after the tension at the lower end of the cable 7 is attenuated, it is wound on the winding drum 11 . When flying the floating platform normally, the traction device 2, the winding device 1 and the cable arrangement 3 are operated to release the cable 7 from the winding drum 11, and the floating platform relies on the buoyancy to pull the cable 7 and release it. When recovering the balloon, the relevant equipment is operated to reversely rotate, and the cable 7 is neatly recovered and wound on t...

Embodiment 2

[0039] In this embodiment, a tethered rope retractable device system is provided with a manual mode and an automatic mode, which can be adjusted according to needs. Different power sources need to be replaced, and the replacement is convenient and safe. When in an emergency, such as a power failure, you can choose the manual mode, and connect the pipeline connected to the hydraulic pump station 5 to the manual oil pump, which can still meet the recovery needs of the floating platform without requiring electric energy at all.

Embodiment 3

[0041] Under normal circumstances, the system only needs one main oil pump motor 51 to meet the requirements, but when this embodiment needs to enter the emergency working mode, there is still a spare oil pump motor 52 to be used at this time, and the two motors run at the same time, which can reach the maximum operation Speed ​​and pulling force, thereby reducing energy consumption.

Abstract

The invention discloses a tie-down rope winding and unwinding device, and belongs to the field of floating-observation platforms. The tie-down rope winding and unwinding device comprises a winding device, a traction device and an unwinding device, wherein the winding device comprises a winding drum connected with a hydraulic transmission device; the traction device comprises a first traction wheel and a second traction wheel which are connected with the hydraulic transmission device; skewed slots which correspond to each other are formed in the first traction wheel and the second traction wheel in an engraved manner; a mooring rope is wound on the first traction wheel and the second traction wheel in 8-shaped repeated, alternate, single-layer and multi-turn manner; the unwinding device is positioned between the winding device and the traction device; and the winding direction and force of the mooring rope are controlled by a plurality of servo motors of the unwinding device. By a hydraulic transmission mode, volume and weight are reduced, and energy consumption is lowered. Moreover, in a mooring rope winding and unwinding process of the device, stable control on winding and unwinding of the mooring rope and protection to the mooring rope are fully considered in the design, and use safety of a tie-down platform is ensured.

Description

technical field [0001] The invention belongs to the field of floating platforms, and more specifically relates to a mooring rope retracting device. Background technique [0002] The tethered balloon is a kind of unpowered balloon aircraft, which belongs to a type of aerostat. The balloon is connected to the ground facilities with a tethered rope. The ball is filled with helium and hovers in the air by buoyancy. It is mainly used for atmospheric boundary layer detection. Balloons can carry self-recording instruments, radio telemetry instruments; or instruments that can transmit information through cables; they can also drop instruments to perform gradient observation at several predetermined heights. Large balls made of polyester film can carry instruments weighing tens of kilograms . As a platform for various communication, monitoring and radar equipment, tethered balloons play a very important role and have unparalleled advantages. [0003] However, helium airship aerosta...
