Novel ship wire drawing box

Abstract

The invention discloses a novel ship wire drawing box. The novel ship wire drawing box comprises a box body, the top of the box body is provided with an end cover, two opposite side faces of the box body are provided with a wire inlet and a wire outlet which are symmetrical, two parallel fixed supporting rods are symmetrically arranged in the box body, the fixed supporting rods abut against and are fixedly connected with the other two opposite side faces, and the height of the fixed supporting rods is flush with the bottom end of the wire inlet. The fixed supporting rods are sleeved with rolling supporting rods, a hollow telescopic sleeve is arranged at the bottom of the box body, the top end of the telescopic sleeve is sealed, a spring is arranged in the telescopic sleeve, the top of the telescopic sleeve is fixedly connected with a supporting frame, and the supporting frame is parallel to the fixed supporting rods. According to the novel ship wire drawing box, when a ship is sagged or arched, the cable in the pull wire box can provide elongation in time along with the change of the state of the ship, and the cable is prevented from being excessively stretched and damaged.

Description

technical field [0001] The invention relates to the technical field of pull boxes, in particular to a novel ship pull box. Background technique [0002] At present, when the ship's cables are laid in the cargo hold area, they will be laid in special cable tubes. Cable pull boxes are installed at the joint points of each cargo hold segment. When the cables are laid, they pass through the pull wire boxes. U-shaped, in order to prevent the random displacement of the cable in harsh sea conditions, the cable is tightly bound with the fixed support rod by steel cable ties, and the cable cannot move up and down in the pull box. [0003] With this cable laying method, under different sea conditions and different cargo loading conditions, the cargo tank hull will have a state of sagging or arching. When this state occurs, the cable will be elongated accordingly, but the maximum elongation of general marine cables The amount must not exceed 3.5‰ of the cable length. At this time, the...

Problems solved by technology

[0002] At present, when the ship's cables are laid in the cargo hold area, they will be laid in special cable tubes. Cable pull boxes are installed at the joint points of each cargo hold segment. When the cables are laid, they pass through the pull wire boxes. U-shaped, in order to prevent the random displacement of the cable under harsh sea conditions, the cable and the fixed support rod are tightly bound together by steel cable ties, and the cable cannot move up and down in the pull box

[0003] With this cable laying method, under different sea conditions and different cargo loading conditions, the cargo tank hull will have a state of sagging or arching. When this state occurs, the cable will be elongated accordingly, but the maximum elongation of general marine cables The amount must not exceed 3.5‰ of the cable length. At this time, the cable is completely fixed in the cable box and cannot be extended with the change of the hull. When the deformation of the hull is large, the cable may be overstretched, resulting in The service life and functional integrity are reduced; when the laying is not in place, the cable may even be directly damaged, seriously affecting the safety of the normal navigation of the ship
