Technical Field

The invention relates to the technical field of cable protection, in particular to a cable abrasion-proof protection device.

Background

The cabin body of the aircraft or the ground equipment has a large number of control cables or power supply cables, the large number of cables sometimes need to penetrate through the whole or partial cabin body structure, and the cabin body is spliced by adopting a segmented structure for the preparation of the structure or other functional requirements, so that a large number of cable cabin penetrating holes exist. Cables need to be run through these holes to other cabin locations. However, vibration of the cabin (or the body) or a maneuvering overload cannot be avoided in most cases during the operation of the aircraft or the ground equipment, which leads to the risk of abrasion at the cable through hole position, and the abrasion results in that the equipment is out of control and power supply capacity is lost, which is extremely fatal for the aircraft or the ground equipment. At present, the cable sleeve is adopted for wear prevention protection, but the cable sleeve needs to be sleeved from the head of the cable, so that the operation is complex. Therefore, there is a need to create a simple and effective method to eliminate the risk points where a large number of cable penetrations may cause wear.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.

The embodiment of the invention provides a cable anti-abrasion protection device, which is mainly used for anti-abrasion protection of a cabin-penetrating through hole part of an aircraft or ground equipment cable. As shown in fig. 1, the cable abrasion-proof protection device includes a split type protection body 2, a stop arm 3, an anti-drop limiting snap ring 4, a locking screw 5, a locking wire snap ring 6, a locking wire hole 7, a spiral clamp 8, and a locking groove 9.

The split type protective body 2 is two arc-shaped or cable-shaped structure bodies with anti-abrasion and anti-collision protection effects, corners are subjected to chamfering treatment, and the materials are metal or nonmetal.

The protected cable 1 is wrapped in the split type protective body 2, and the split type protective body 2 is positioned at a through hole of the protected cable 1 penetrating through the cabin body partition board when in use.

The spiral clamps 8 are two groups and are respectively sleeved at two ends of the split type protection body 2, and the spiral clamps 8 are locked by the locking screw rods 5, so that the split type protection body 2 is tightly attached to the protected cable 1.

Two ends of each structural body of the split type protective body 2 are respectively provided with a plurality of fixed locking grooves 9, and each locking groove 9 is correspondingly provided with one locking arm 3. The stop arm 3 is L-shaped, and one end of the stop arm is provided with a fixing sheet for fixing a locking screw. The transversal door font of personally submitting of locking groove 9, and go up the frame and be cavity to guarantee that the one end that locking arm 3 set up the stationary blade can operate in locking groove 9. During the use, the stationary blade of stopping arm 3 one end is fixed in via hole cabin body baffle, and the stationary blade of the other end passes locking groove 9 to be located locking groove 9. The locking arm 3 is adjusted to compress the plane of the cabin partition plate, the locking screws on the fixing pieces are locked, the bolts are compressed on the upper edge of the locking groove 9, and the whole protection device is prevented from bouncing along the cable under the vibration condition by the protection structure.

As a specific embodiment of the present invention, in order to prevent the split type protection body 2 from falling off due to the separation of the spiral clamp 8 under the vibration condition, the split type protection body 2 is provided with the anti-falling limit snap ring 4, and the spiral clamp 8 is passed through the anti-falling limit snap ring 4.
