Description

TECHNICAL FIELD

[0001] The utility model belongs to military cable support field, especially relate to a six hole type warship cable damping combination device. BACKGROUND

[0002] The existing warship cable is usually fixed on the wall at a high position by welding or bolt, and then the warship cable is laid on the top of the cable bracket. Such installation structure is not convenient for actual cable construction and maintenance because the cable installation position is high. In order to ensure the safety of the cable, the existing cable bracket is usually of a rectangular structure. The cable needs to pass through the cable bracket for installation. Such installation structure is also not convenient for later maintenance and additional cable. The existing cable is usually directly installed on the cable bracket by a steel hoop. The damping protection effect is not good. Such installation structure also affects the service life on the submarine with bumps. Chinese patent CN102853165B discloses a whole convex stretching type multifunctional cable bracket. The cable bracket includes a cable support plate and a bracket guide plate. The cable support plate and the bracket guide plate are integrally formed by whole bidirectional convex stretching stamping. The two ends of the cable support plate are respectively provided with a first reinforcing rib and a second reinforcing rib. The middle part of the cable support plate is bidirectionally stretched inward to form a "convex and concave" type groove. The first reinforcing rib and the second reinforcing rib are combined with the "convex and concave" type groove to form a "Z" type cable support plate. The two ends of the bracket guide plate are inwardly turned to form a first vertical rib and a second vertical rib. The whole bidirectional convex stretching stamping forming process is adopted to integrally form the cable bracket without welding. The cable bracket has the characteristics of light structure, beautiful appearance, strong bearing capacity, strong corrosion resistance, convenient installation, easy replacement, low price and the like. However, the above-mentioned cable bracket is generally only suitable for cable laying. The bracket is not suitable for effectively fixing the cable pipe and cannot damp the cable pipe. In addition, the existing warship cable is easily subjected to a large impact force and shaking during the running of the warship. Long-time shaking can cause the warship cable and the electrical equipment interface to fall off or loosen, resulting in poor contact and inducing safety accidents. In addition, the submarine has very strict requirements for vibration and noise. The vibration wave of the submarine cable transmitted to the bulkhead has a certain negative impact on the sound insulation of the submarine. CONTENT OF THE UTILITY MODEL
