Description

Technical Field

[0001] The utility model belongs to the technical field of ship cable laying, and in particular relates to a drag-reducing and laying tool for ship cables. Background Art

[0002] During the shipbuilding process, laying cables is an important step in the shipbuilding process. Currently, cable laying on ships is usually carried out on cable trays, and construction workers usually pull the ends of the cables to perform cable laying operations.

[0003] When existing cables are pulled and laid, the cables will directly rub against the surface of the ship, which will not only easily damage the cable surface, but also the friction between the cable and the ship will increase the resistance, making the pulling and laying more difficult. It requires the cooperation of multiple people and the work efficiency is low. Therefore, we proposed a drag-reducing pulling and laying tool for ship cables. Utility Model Content

[0004] The purpose of this utility model is to provide a drag-reducing pulling and laying tool for ship cables. By setting a conveying roller, specifically by the staff pulling the cable, the cable drives the conveying roller to rotate, and the rotating shaft rotates on the conveying seat, and at the same time drives the limiting roller to rotate on the fixed frame, which can make the pulling and laying smoother, reduce friction, and thus reduce resistance, making pulling and laying easier. At the same time, reducing friction can prevent the cable surface from being damaged, and solves the problem that the cable will directly rub against the ship surface when pulling and laying, which not only easily damages the cable surface, but also the friction between the cable and the ship will increase resistance, making pulling and laying more difficult.

[0005] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a drag-reducing pulling and laying tool for ship cables, comprising a conveying seat, a cable is arranged above the conveying seat, a accommodating cavity is opened on the top of the conveying seat, and limiting components are arranged on the front and back sides of the cable, and the two limiting components are symmetrically arranged with the cable as the center, and the structures contained in the two limiting components are the same, and a plurality of conveying rollers are arranged inside the accommodating cavity opened on the top of the conveying seat, and a driving push rod is fixedly connected to the bottom of the inner wall of the accommodating cavity. By arranging the conveying rollers, specifically by the staff pulling the cable, the cable drives the conveying rollers to rotate, and the rotating shaft rotates on the conveying seat, and at the same time drives the limiting rollers to rotate on the fixed frame, which can make the pulling and laying smoother, reduce friction, thereby reducing resistance, making the pulling and laying easier, and reducing friction can prevent the cable surface from being damaged;

[0007] The limiting component includes a connecting plate, and a plurality of fixing frames are fixedly connected to the side of the connecting plate close to the cable. The plurality of fixing frames are rotatably connected to the limiting rollers inside. By setting the limiting component, specifically after the cable is placed on the conveying seat, the push rod is started to drive the push block to move to the left, and the two slides slowly approach each other under the action of the spring elasticity, so that the limiting roller contacts the cable surface and stops, which can limit the cable, prevent the cable from running off or falling from the conveying seat, and improve the stability during pulling and laying.

[0008] Furthermore, a connecting frame is fixedly connected to the side of the connecting plate away from the cable, a slide is fixedly connected to the bottom of the connecting frame, openings are provided on the front and back of the accommodating cavity, the openings are adapted to the slide, a slide groove is provided at the bottom of the slide, and the connecting frame is used to connect the slide and the connecting plate so that the slide and the connecting plate can move synchronously.

[0009] Furthermore, the inner wall of the slide groove is slidably connected to a slide rail, the bottom of the slide rail is fixedly connected to the bottom of the inner wall of the accommodating cavity, and the bottom of the slide seat contacts the bottom of the inner wall of the accommodating cavity. When the slide seat moves, it will slide on the slide rail through the slide groove, enabling the slide seat to move in a straight line, making the movement more stable.

[0010] Furthermore, an inclined plate is fixedly connected to the left side of the slide, a straight slot is provided inside the inclined plate, and a fixed plate is fixedly connected to the right side of the slide, and a stabilizing rod is fixedly connected to the back side of the fixed plate, and a spring is sleeved on the outer side of the stabilizing rod, and the back side of the stabilizing rod passes through the conveying seat and extends to the outside, and the stabilizing rod is slidably connected to the conveying seat, and one end of the spring is fixedly connected to the fixed plate, and the other end of the spring is fixedly connected to the inner wall of the accommodating cavity. By setting the inclined plate, the inclined block can push the inclined plate, thereby driving the slide to move, so that the two slides move away from each other, and the spacing can be adjusted to facilitate the placement of the cable.

[0011] Furthermore, the right output end of the driving push rod is fixedly connected to a push block, a hole is opened inside the push block, a push rod is fixedly connected to the inner wall of the hole, and two inclined blocks are fixedly connected to the outer surface of the push rod. The outer surface of the push rod contacts the inner wall of the straight slot opened inside the inclined plate, and the side of the inclined block close to the inclined plate is set as an inclined surface, and the side of the inclined block close to the inclined plate is in contact with the outer surface of the inclined plate. Since the contact surface between the inclined block and the inclined plate is set as an inclined surface, the inclined plate can be pushed smoothly, and the contact area is increased to improve stability.

[0012] Furthermore, a rotating shaft is fixedly connected to the inside of the conveying roller, and the front and back sides of the rotating shaft are rotatably connected to the conveying seat. The bottom of the cable contacts the top of the conveying roller, and the outer surface of the cable contacts the outer surface of the limiting roller. Both the conveying roller and the limiting roller can reduce friction and resistance, and can pull and lay the cable more efficiently, and the conveying roller supports the cable through the rotating shaft.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a conveying roller. Specifically, when the staff pulls the cable, the cable drives the conveying roller to rotate, and the rotating shaft rotates on the conveying seat, and at the same time drives the limiting roller to rotate on the fixed frame, which can make the pulling and applying smoother, reduce friction, thereby reducing resistance, making the pulling and applying easier, and reducing friction can prevent the cable surface from being damaged.

[0015] 2. The utility model sets a limit component. Specifically, after the cable is placed on the conveying seat, the push rod is started to drive the push block to move to the left. The two slides slowly approach each other under the action of the spring elasticity, so that the limit roller stops after contacting the cable surface. It can limit the cable, prevent the cable from running off or falling from the conveying seat, and improve the stability during pulling and laying.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
