Description

Technical Field

[0001] The utility model belongs to the technical field of ship cable laying, and in particular relates to a shock absorber component and a ship cable shock absorbing receiving part. Background Art

[0002] How to improve the bearing capacity of ship cable receiving parts in a limited space, the flexibility of construction and the vibration and noise reduction performance, and the overall aesthetics are the development trends of modern shipbuilding. Chinese patent CN102679041A discloses an integral convex drawing and stamping type cable hook bracket for ships and marine engineering, including a hook as the main body to carry the cable and a locking piece for fixing the cable, and a fixed support foot for the cable hook installation. Its characteristics are that the hook bracket, the fixed locking piece, and the fixed support foot are all made by an integral convex drawing and stamping process, and are fixed by hooking and plugging with bolts, without welding and processing to form a whole. This invention changes the traditional manufacturing process, changing the original 3.0mm to 4.0mm steel plate thickness to 2.0mm steel plate thickness, which not only improves the safe load capacity, but also reduces the weight of a single product by more than 25%. It has the advantages of light structure, beautiful shape, strong bearing capacity, strong corrosion resistance, easy installation, easy replacement, and low price, and is particularly suitable for use on ships and marine engineering. The cable hook bracket disclosed in the above document has poor shock absorption effect and limited cable laying. Chinese patent CN219371922U discloses a cable elastic support. The cable elastic support includes a U-shaped tight-hook cable bracket, an elastic shock absorber, a mounting foot and a fixing bolt. The U-shaped tight-hook cable bracket is fixedly connected to the elastic shock absorber by a locking bolt, one end of the mounting foot is fixedly connected to the elastic shock absorber by a fixing bolt, and the other end is welded to the bulkhead. The support is used for laying cables on underwater submersibles, and is used to fix cables connected to vibration sources such as engines and generators. Although the above technical solution solves the noise problem caused by the vibration frequency of the vibration source being transmitted to the outer wall of the submersible through the cable to a certain extent. However, it has been verified experimentally that its shock absorption and noise reduction effect is not ideal, and the structural stability and maintenance convenience are difficult to achieve the design expectations. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a shock absorber assembly and a ship cable shock-absorbing connector with a simple structure, convenient maintenance, high stability, adjustable vibration reduction stiffness, small zero point offset, ideal shock absorption and noise reduction effect, large cable laying volume and overload protection function.

[0004] To solve the above technical problems, the utility model is implemented as follows:

[0005] A shock absorber assembly comprises four cross shafts, four groups of square rubbers, four connecting arms and an outer frame with two longitudinally arranged square through grooves on two sides; the two outer frames are spaced a certain distance apart and are reversely symmetrical; the cross shaft is placed in the square through groove; the square rubber comprises four rubber units and is respectively placed in the square space between the inner wall of the square through groove of the outer frame and the four corners of the cross shaft in an interference fit manner; the two ends of the connecting arm are respectively fixedly connected to the two ends of the cross shaft.

[0006] The ship cable shock-absorbing receiving part comprises a U-shaped cable bracket, a shock absorber assembly and a fixing mechanism; one end of the shock absorber assembly is fixedly connected to one side of the U-shaped cable bracket; the other end of the shock absorber assembly is fixedly connected to the fixing mechanism;

[0007] The shock absorber assembly includes two outer frames with two longitudinally arranged square through grooves on each side, four cross shafts, four groups of square rubbers and four connecting arms; the two outer frames are spaced a certain distance apart and are reversely symmetrical; the cross shaft is placed in the square through groove; the square rubber includes four rubber units and is placed in the square space between the inner wall of the square through groove of the outer frame and the four corners of the cross shaft in an interference fit manner; the two ends of the connecting arm are fixedly connected to the two ends of the cross shaft respectively.

[0008] Furthermore, the utility model provides a stamping groove on the U-shaped cable bracket; a clamping plate is transversely provided on the side wall of the U-shaped cable bracket; and the clamping plate can slide up and down along the side wall of the U-shaped cable bracket.

[0009] Furthermore, the number of the shock absorber assemblies of the utility model is two and they are spaced a certain distance apart longitudinally.

[0010] Furthermore, the fixing mechanism of the utility model includes a connecting plate and a welding foot; the welding foot is fixed on the front side of the connecting plate.

[0011] Furthermore, the utility model provides an elongated hole in the welding foot.

[0013] The utility model has a simple structure, convenient maintenance, high stability, adjustable vibration damping stiffness, small zero point offset, ideal shock absorption and noise reduction effect, and an overload protection function. When subjected to an extreme load, if the shock absorber assembly moves downward too much, the walls of the two shock absorber assemblies contact each other to prevent the U-shaped cable bracket from continuing to move downward, thereby playing a protective role and preventing the square rubber from being damaged due to excessive pressure. The vibration damping stiffness of the utility model can be flexibly changed by adjusting the length of the connecting arm and the hardness of the square rubber, and is adaptable to various load-bearing weights and easy to operate. In addition, since the utility model adopts a 4-connecting arm type shock absorber assembly mode, the redundant design of the system is increased, and the stability of the system is enhanced. Under the condition of the same cable laying amount, it has a better shock absorption and noise reduction effect. This shock absorber assembly mode is suitable for scenarios with a large amount of cable laying. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The shock absorber assembly 6 includes four cross shafts 2, four sets of square rubbers 3, four connecting arms 4 and two outer frames 1 with two longitudinally arranged square through grooves on the two sides; the two outer frames 1 are spaced a certain distance apart and are reversely symmetrical; the cross shaft 2 is placed in the square through groove; the square rubber 3 includes four rubber units and is placed in the square space at the four corners between the inner wall of the square through groove of the outer frame 1 and the cross shaft 2 in an interference fit manner; the two ends of the connecting arm 4 are fixedly connected to the two ends of the cross shaft 2. The utility model is provided with a stamping groove on the U-shaped cable bracket 5; a clamping plate is provided transversely on the side wall of the U-shaped cable bracket 5; the clamping plate can slide up and down along the side wall of the U-shaped cable bracket 5. The number of shock absorber assemblies 6 of the utility model is two and they are spaced a certain distance apart longitudinally. The fixing mechanism of the utility model includes a connecting plate 7 and a welding foot 8; the welding foot 8 is fixedly arranged on the front of the connecting plate 7. The utility model has an extended hole in the welding foot 8. Buckle covers 9 are provided at the ends of the cross shaft 2 at the two ends of the connecting arm 4. The buckle cover 9 is mainly used to fix the cross shaft 2 and the square rubber 3 to prevent lateral movement. The screw is inserted into the cross shaft 2 through the threaded hole in the center of the buckle cover 9 and fixedly connected with the cross shaft 2.

[0023] See also Figure 2As shown, in the specific design, the U-shaped cable bracket 5 of the utility model is used to place the cable, the stamping groove of the U-shaped cable bracket 5 is used to increase the rigidity, the clamping plate 11 on the U-shaped cable bracket 5 is used to clamp the cable, and the clamping plate 11 of the U-shaped cable bracket 5 can slide up and down along the U-shaped cable bracket 5.

The upper and lower welding feet are welded on the wall surface, still to save the space between the U-shaped cable bracket 5 and the wall surface to the maximum extent. When encountering the limit load, when the connecting arm 4 is twisted to a certain angle, the two inner wall surfaces of the shock absorber assembly 6 collide, and the connecting arm 4 stops rotating at this time, avoiding the square rubber from being damaged due to excessive pressure. The welding foot structure arrangement of the utility model leaves welding fault tolerance space, which is convenient for on-site installation. The welding foot 8 bolts are arranged in the direction of the cable axis for assembly, considering that there is a large space in the direction of the cable axis. The utility model is equivalent to being arranged in four groups of vibration damping units, but every two groups are integrated into one structure to form a set of vibration damper assemblies, which reduces the space, increases the stability of the system, and expands the applicability of the system. The structural design of the utility model makes the welding foot 8 simple in structure, and an extension hole is opened on the welding foot, leaving a welding fault tolerance margin, which is convenient for installation after welding, and convenient for processing and operation by on-site installers.
