Description

Cable release hook flexible locking cable release device

technical field

The invention relates to a kind of special equipment installed on the wharf and used for twisted cables and mooring cables of ships, in particular to a flexible locking and cable-releasing device capable of quickly releasing cables.

Background technique

When the ship is docked at the dock, the crew will tie the cable to the bitt on the dock so that the ship is stable and will not drift away. Especially in large oil and petrochemical terminals, it is required that the bolts be fastened, and it is hoped that they can be released in time in an emergency, especially when there are few operators and strong wind and waves . Considering more dangerous occasions, such as a wharf or ship on fire, in order to minimize losses, at this time, it is extremely urgent to separate the wharf from the ship in time.

However, the bollard used on traditional piers is usually just a post, and the rope needs to be wound several times. For large ships, several bollards need to be wound around several bollards to tie the ship. When an emergency occurs and the ship needs to leave quickly, the staff are often in a hurry, and even pose a threat to the personal safety of the dock personnel.

Contents of the invention

The technical problem to be solved by the present invention is to provide a flexible locking and uncable hook release device that can quickly and safely uncable.

In order to achieve the above-mentioned purpose, the solution adopted by the present invention to solve the above-mentioned technical problems is: a flexible locking and de-cable device for the de-cable hook, which is arranged inside the hook frame and is composed of an operating rod, a hook bolt, an anchor hook and a linkage mechanism, wherein, The bottom of the operating rod is connected with a trigger lever interacting with the linkage mechanism, and the trigger lever is connected to the hook frame axis A; the hook bolt is connected to the hook frame axis D, including two parts: the bolt body and the bolt tongue. The body locks the anchor hook, and the bolt tongue is locked by the linkage mechanism. Through the dual clamping of the anchor hook and the hook bolt, the present invention has a very superior and stable locking function, and at the same time, through the linkage of the linkage mechanism, the effect of quick release of the cable can be achieved. Because the clamping structure such as positioning holes is not used, the clamping of the anchor hook and the hook bolt is realized through the transmission mechanism of point, line and surface contact, which has the structural characteristics of flexible locking and uncable device.

On the basis of the above scheme, the linkage mechanism includes a fork bushing, a roller and a spring, wherein the fork bushing is connected to the hook frame shaft B, and includes two arms, one arm abuts against the pull lever, and the other A roller is fixed on the top of a moment arm, and the roller is clamped on the bolt tongue; one end of the spring is fixedly connected to the fork bushing, and the other end is fixedly connected to the bolt body of the hook bolt.

The inner side of the bolt body is provided with an upper stopper, which rotates around the central axis D of the bolt body; an upward handle is connected to the bolt tongue, and the handle is used to move the bolt tongue. In the working condition of the mooring cable, the upper block is pressed on the anchor hook, and the roller acts as a limit point for locking the hook bolt so that it cannot rotate around the axis. When the whole uncable device needs to be reset after being released, the handle is pushed until the tongue of the hook bolt returns to the horizontal position and is locked by the roller. During this process, the spring returns to the tensioned state.

The roller is installed on the shaft C at the top of the arm of the fork sleeve, and rotates around the shaft C. The rotation of the roller can help reduce friction between the roller and the hitch when the release action of the lever is performed.

The spring and the bolt body are fixed by bolts, which can drive the hook bolt to rotate around its central axis.

The anchor hook is connected with the hook frame axis E, and is divided into a hook and a cantilever, and the top of the cantilever is stuck below the stopper on the hook bolt. In this state, the upper block acts as a limiting surface for anchor hook clamping, so that it cannot rotate around the axis E.

The de-cable working principle of the present invention is:

The staff pulls the operating lever to make the lever at the bottom rotate clockwise around the A-axis, and the lever pushes the fork shaft sleeve to rotate counterclockwise around the B-axis as a whole, which should be installed on the roller on the top of the other arm It also rotates counterclockwise around the B axis. At this time, the roller rotates counterclockwise around the C axis. After the roller is shifted, the tongue of the hook bolt under the roller is released; at the same time, the spring is tightened, and under the pull of the spring, the hook bolt rotates 90 degrees clockwise around its central axis D, and the upper stop that was originally in the horizontal position Also turn to vertical setting thereupon, the anchor hook cantilever top that is stuck below the upper stopper is released. Finally, under the tension of the cable, the anchor hook rotates around the axis E to release the cable.

The concept of the flexible locking and uncable device proposed by the present invention uses points, lines and surfaces to lock each other to achieve the purpose of stable locking, thereby improving the time-consuming process of locking and uncables caused by fixed connections such as positioning holes. , Strenuous situation.

The advantages of the present invention are:

1. Compared with traditional bollards, it reduces the labor intensity of workers, improves labor efficiency, and enhances safety and reliability;

2. Realize manual operation and release, only one action can complete all operations, the action is fast, and it can be released safely when the cable has no load or reaches full working load;

3. The detachment device is installed inside the hook frame to prevent other objects from interfering. The design of the mechanism adopts a flexible transmission device. The reaction force during the detachment operation will not be transmitted to the manual operating lever, and the operation is safe;

4. Under the working condition of the cable, the flexible locking device is self-locking, and the tension of the cable will not accidentally unhook within the strength of the flexible locking device, which is very convenient for normal use.
