Description

Cable tray connection structure

Technical Field

The utility model belongs to the technical field of boats and ships sampan's piece technique and specifically relates to a cable tray connection structure is related to.

Background

Ship outfitting is one of the important products in the ship manufacturing industry, and plays an important role in the construction of ships. The marine cable bracket is mainly used for accommodating cables on a ship so as to realize reasonable and regular arrangement of the cables.

Most rooms in the superstructure of a ship are provided with a ceiling, and a large number of cables are arranged between the steel deck of the ship body and the ceiling. The cable is fixed by the cable tray, and the cable tray passes through the connecting piece and is connected with deck bottom girder steel. Due to the fact that the marine environment is severe, ships often bump through sea waves, high requirements are provided for the connection reliability of the cable bracket and the steel beam at the bottom of the deck, and in addition, sea wind erosion easily causes corrosion of the welding position of the cable bracket and the connecting piece and the connecting position of the steel beam at the bottom of the deck and the connecting piece, so that damage and service life are reduced. Therefore, how to improve the connection reliability of the cable tray under the deck is a technical problem which needs to be solved urgently.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cable tray connection structure with high reliability.

The purpose of the utility model is realized like this: the utility model provides a cable tray connection structure, includes the C type connecting piece that sets up in pairs, C type connecting piece upper end and deck bottom girder steel welded fastening, lower extreme and cable tray welded fastening are equipped with the rectangle reinforcing plate in the opening of C type connecting piece, on the rectangle reinforcing plate along, dorsal part and down along respectively with C type connecting piece perpendicular welded fastening, the rectangle reinforcing plate passes through bolted connection with cable tray both sides. The utility model discloses a cable tray connection structure through adopting C type connecting piece, has increased the welded connection area of cable tray and deck bottom girder steel, has improved vertical joint strength to pass through bolted connection through addding rectangle reinforcing plate and cable tray both sides, improved transverse connection intensity. To sum up, the utility model discloses a cable tray connection structure has advantages such as simple structure, construction convenience, connection reliability height.

As the utility model discloses a further improvement, the cable tray cross-section is the U type, including the bottom plate and connect the riser in the bottom plate both sides, be equipped with the bound hole on the bottom plate, C type connecting piece lower extreme inserts in the opening of cable tray and is close to the riser setting, further improves the connection reliability.

As a further improvement, the rectangular reinforcing plate is close to the vertical plate, so that the bolt connection is convenient.

As a further improvement of the utility model, the strapping hole is long banding and sets up in pairs, and the strapping of being convenient for passes the strapping hole and ties up the cable and fix at the bottom plate downside.

As a further improvement, a plurality of air holes are distributed between the pair of binding holes, the air permeability of the binding positions is improved, and the temperature of the cable is too high.

As a further improvement, the air holes are arranged along the longitudinal dislocation, so that the influence of the air holes on the strength of the cable bracket is reduced.

As the utility model discloses a further improvement, the bolt passes cable tray and rectangle reinforcing plate in proper order and fixed through two nuts, avoids not hard up because of the connection that boats and ships jolt vibrations and lead to through meeting the wave.

Drawings

Fig. 1 is a schematic view of the cable tray connection structure of the present invention.

Fig. 2 is a side view of the cable tray connecting structure of the present invention.

Fig. 3 is a bottom view of the cable tray connecting structure of the present invention.

The connecting device comprises a 1C-shaped connecting piece, 2 deck bottom steel beams, 3 cable brackets, a 3A bottom plate, a 3B vertical plate, 4 rectangular reinforcing plates, 5 strapping holes, 6 air holes, 7 cables and 8 strapping tapes.

Detailed Description

The connecting structure of the cable bracket 3 shown in fig. 1-3 comprises C-shaped connecting pieces 1 which are arranged in pairs, wherein the upper ends of the C-shaped connecting pieces 1 are welded and fixed with a steel beam 2 at the bottom of a deck, and the lower ends of the C-shaped connecting pieces are welded and fixed with the cable bracket 3.

Be equipped with rectangle reinforcing plate 4 in the opening of C type connecting piece 1, rectangle reinforcing plate 4 is gone up along, dorsal part and lower edge and is fixed with the perpendicular welded joint of C type connecting piece 1 respectively, and bolted connection is passed through with 3 both sides of cable tray to rectangle reinforcing plate 4.

Specifically, as shown in fig. 2, the cable bracket 3 has a U-shaped cross section, and includes a bottom plate 3A and vertical plates 3B connected to two sides of the bottom plate 3A. The lower end of the C-shaped connecting piece 1 is inserted into an opening of the cable bracket 3 and is arranged close to the vertical plate 3B. The rectangular reinforcing plate 4 is fixed on the inner side and the outer side of the opening of the C-shaped connecting piece 1, namely, is close to the vertical plate 3B, so that the bolt connection is facilitated. The bolts sequentially penetrate through the vertical plate 3B and the rectangular reinforcing plate 4 of the cable bracket 3 and are fixed through double nuts, so that connection looseness caused by bumping and shaking of sea waves in the ship is avoided.

As shown in fig. 3, the bottom plate 3A is provided with a binding hole 5. The binding holes 5 are long and are arranged in pairs, so that the binding tapes 8 can conveniently pass through the binding holes 5 to bind and fix the cables 7 on the lower side of the bottom plate 3A. A plurality of air holes 6 are distributed between the pair of binding holes 5, so that the air permeability of the binding position is improved, and the temperature for placing the cable is too high. The air holes 6 are arranged along the longitudinal direction in a staggered manner, so that the influence of the arrangement of the air holes 6 on the strength of the cable bracket 3 is reduced.

The cable tray connection structure of this embodiment through adopting C type connecting piece 1, has increased the welded connection area of cable tray 3 with deck bottom girder steel 2, has improved longitudinal connection intensity to pass through bolted connection through addding rectangle reinforcing plate 4 and cable tray 3 both sides, improved transverse connection intensity. Through the unique design of the binding holes 5 and the air holes 6, the strength of the cable bracket 3 is ensured, and meanwhile, the air permeability of the binding position is improved.

The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
