Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft structure design, and relates to a steering device for a high-speed cable under loose constraint conditions at both ends. Background Art

[0002] When an aircraft is towing a target drone or other towed object, the towed object must be released and retrieved. The cable retraction device is installed at a location favorable to the aircraft's center of gravity, and the towing cable must be steered within the cabin to ensure optimal force transmission. Furthermore, when the towed object is close to the fuselage, the turbulence caused by the fuselage causes the ends of the cable to swing and oscillate, potentially causing the cable to jump during operation. This is significantly different from the traditional control cable system, which has a small travel, slow speed, and uniform force distribution within the guide fixed pulley. Utility Model Content

[0003] The purpose of the utility model is to provide a steering device for a high-speed cable under loose constraints at both ends. The utility model can effectively restrain the swing of the high-speed cable at the turning point and maintain stable transmission.

[0004] Technical Solution: A steering device for high-speed cables with loose constraints at both ends, comprising a steering pulley assembly disposed at the cable's steering point, with anti-bounce assemblies also provided at both the inlet and outlet ends of the steering point. The cable enters through the anti-bounce assembly at the inlet of the steering point, passes through the steering pulley assembly for steering, and then exits through the anti-bounce assembly at the outlet of the steering point.

[0005] In the aforementioned steering device for high-speed cables under loose constraints at both ends, the anti-jump component includes a support, a wire-passing hole is axially provided on the support, two pairs of roller bearings are axially provided in the wire-passing hole, and the two pairs of roller bearings are staggered to form an anti-jumping hole; the cable passes through the anti-jumping hole.

[0006] In the steering device of the high-speed cable under the aforementioned loose constraint conditions at both ends, the angle formed by the two pairs of roller bearings is staggered to be 90°.

[0007] In the aforementioned steering device for the high-speed cable under the loose constraint conditions at both ends, the wire holes are arranged as square holes.

[0008] In the aforementioned steering device for high-speed cables under loose constraints at both ends, the steering pulley assembly is composed of a group of pulleys arranged in pairs, and the cable passes through the pulley grooves formed by the pairs.

[0009] In the aforementioned steering device for a high-speed cable under loose constraint conditions at both ends, the support is made of aluminum alloy.

[0010] Beneficial effects

[0011] The utility model installs two pairs of staggered roller bearings at both ends of the turning point to restrain the cable jump at both ends. After the cable enters the turning stage, the two pulley groups are installed in the form of clamps to change the movement direction of the cable, further restraining the shaking of the cable in the up and down and left and right directions, preventing the cable from falling out of the guide due to oscillation and swinging. This structure effectively changes the transmission direction of the cable and prevents the cable from falling out of the guide device due to jumping, which significantly improves the reliability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 It is a schematic diagram of the anti-jump component structure. DETAILED DESCRIPTION

[0014] The following is a detailed description of a steering device for a high-speed cable under loose constraints at both ends of the utility model with reference to the accompanying drawings:

[0015] Example 1. A steering device for a high-speed cable with loose constraints at both ends, comprising: Figure 1 and Figure 2 As shown, it includes a steering pulley assembly 2 arranged at the turning point of the cable 1, and anti-jumping components 3 are also provided at the inlet and outlet ends of the steering point; after the cable 1 passes through the anti-jumping component 3 at the inlet end of the steering point, it passes through the steering pulley assembly 2 for steering, and then passes out from the anti-jumping component 3 at the outlet end of the steering point.

[0016] The anti-jump assembly 3 includes a support 31, which has a wire hole 32 axially disposed on the support 31. Two pairs of roller bearings 33 are axially disposed within the wire hole 32. The two pairs of roller bearings 33 are staggered to form an anti-jump hole 34; the cable 1 passes through the anti-jump hole 34. Two pairs of staggered roller bearings are disposed at the entrance and exit of the cable turning point, and the cable's jump is significantly reduced after passing through the roller bearings.

[0017] The angle formed by the two pairs of roller bearings 33 is 90°.

[0018] The aforementioned wire-passing hole 32 is arranged in a square hole.

[0019] The aforementioned deflection pulley assembly 2 consists of a set of paired pulleys, through which the cable 1 passes. After entering the deflection fixed pulley, the bouncing cable still has the potential to escape the fixed pulley's restraints. Therefore, a paired fixed pulley is added to the deflection fixed pulley to ensure that the cable is within the fixed pulley's guide groove, achieving stable deflection and restraint of the oscillating cable.

[0020] The aforementioned support 31 is made of aluminum alloy.
