Description

Technical Field

[0001] The present invention relates to the technical field of ships, and particularly relates to a device and a usage method for adjusting the cable allowance in a transition box. Background Art

[0002] A cable is a power or signal transmission device composed of several or several groups of wires. It is made of one or more mutually insulated conductors and an outer insulating protective layer, and is a wire that transmits electricity or information from one place to another. Usually, it is a cable similar to a rope twisted by several or several groups of wires. Each group of wires is mutually insulated and often twisted around a center, and the whole is covered with a highly insulating covering layer. The cable has the characteristics of internal power conduction and external insulation.

[0003] For the cable laying of ships, generally, the method of laying through cable pipes is adopted. Usually, it is necessary to add a transition box on the deck. The cable passes through the cable pipe of the transition box. When laying the cable, a winch needs to be operated at the bow to pull the cable, resulting in insufficient allowance in each transition box. During the navigation process, the cable cannot move freely with the free rollers in the box, and the insufficient allowance causes cable wear. Summary of the Invention

[0004] The purpose of the present invention is to provide a device and a usage method for adjusting the cable allowance in a transition box, which can adjust the cable allowance in the transition box according to requirements and reduce cable wear.

[0005] In order to achieve the above-mentioned invention purpose, the following technical solutions are adopted for the device and the usage method for adjusting the cable allowance in the transition box of the present invention:

The bracket is arranged on the top of the mounting seat, and the first link group and the second link group are symmetrically arranged at the bottom of the mounting seat; both the first link group and the second link group include an upper link and a lower link. The top end of the upper link is hinged to the mounting seat, the lower end of the upper link is hinged to the lower link through a rotating shaft, the upper end of the lower link is connected to the rotating shaft, and the lower end of the lower link is hinged to the bottom wall of the housing; a bidirectional hydraulic cylinder for driving the elevating frame to lift is arranged on the elevating frame. The two telescopic ends of the bidirectional hydraulic cylinder are respectively connected to the rotating shafts of the first link group and the second link group; a vertically arranged sliding column is arranged on the bottom wall of the housing. The cylinder barrel of the bidirectional hydraulic cylinder is fixed on a sliding seat. The sliding seat is provided with a collar sleeved on the sliding column, and the length direction of the sliding seat is perpendicular to the telescopic direction of the bidirectional hydraulic cylinder.

[0007] Preferably, the bin body is provided with an installation component that abuts against the inner wall of the transition box.

Through the setting of the installation component, it is convenient to disassemble and install the bin body in the transition box. During disassembly and installation, only the connecting sleeve needs to be rotated. Moreover, there is no need to drill holes in the transition box. The bin body can be fixed only by abutting against it with the pressing plates on both sides, and the installation position of the bin body is convenient to adjust.

[0008] Preferably, a rotating ring is sleeved on the outer periphery of the rotating shaft, and the telescopic end of the bidirectional hydraulic cylinder is fixedly connected to the rotating ring.

[0009] Preferably, the bin body is provided with vertically arranged guide posts, and the mounting seat is provided with guide rings sleeved on the guide posts. Through the setting of the guide posts, the vertical lifting of the mounting seat is ensured.

[0013] Preferably, the bracket includes a base. The base is provided with an arc-shaped groove adapted to the cable. A pulley frame is arranged above the base. The base and the pulley frame are connected by fasteners. Pulleys in contact with the cable are installed on the pulley frame, and the cable is located between the pulley and the arc-shaped groove.

[0014] Preferably, a plurality of bin bodies are arranged along the arrangement direction of the cable.

[0015] A method for using a device for adjusting the cable allowance in a transition box includes the following steps:

[0016] (1) According to the size of the transition box, adjust the connecting sleeve rod so that the pressing plate abuts against the inner wall of the transition box;

[0017] (2) According to the requirement of the cable allowance in the transition box, control the extension degree of the bidirectional hydraulic cylinder. The extension of the bidirectional hydraulic cylinder drives the bracket to rise, so that a height difference is formed between the position of the arc-shaped groove of the bracket and the cable pipe of the transition box;

[0018] (3) Install the cable. The cable passes through the cable pipe of the transition box and enters the transition box, and then passes through the bracket to form a curved layout and then exits the transition box;

[0019] (4) After the cable laying is completed, the double-acting hydraulic cylinder contracts, driving the bracket to descend, and then the pulley frame is disassembled from the base;

[0020] (5) Adjust the connecting sleeve rod so that the first connecting screw rod and the second connecting screw rod are retracted into the connecting sleeve rod, the pressing plate is separated from the inner wall of the transition box, and the bin body is disassembled from the transition box.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The present invention sets a bin body in the transition box to lift the cable during cable laying, so that there is a height difference between the arc-shaped groove position of the bracket and the cable pipe of the transition box. After the cable laying is completed, the bin body can be removed. At this time, there is a surplus of the cable in the transition box, reducing the phenomenon of cable wear;

[0023] 2. The present invention sets a lifting frame inside the bin body. By lifting and lowering the lifting frame, the height difference between the arc-shaped groove position of the bracket and the cable pipe of the transition box is controlled, thereby controlling the cable surplus, realizing the adjustment of the cable surplus in the transition box, ensuring sufficient surplus, and improving the scope of application;

[0024] 3. The lifting and lowering mode of the lifting frame of the present invention is that the rotating shafts of the first connecting rod group and the second connecting rod group are driven by a double-acting hydraulic cylinder to approach each other, and then the rotation of the upper connecting rod and the lower connecting rod is driven, thereby driving the movement of the bracket. At the same time, the length direction of the sliding seat is perpendicular to the telescopic direction of the double-acting hydraulic cylinder. Combined with the support of the upper connecting rod and the lower connecting rod, a stable support structure is formed to realize the stable regulation of the height of the bracket.
