Description

Technical Field

[0001] The invention belongs to the technical field of dock equipment, and in particular relates to an anti-cable-detachment safety cable-detachment hook. Background Art

[0002] After the ship docks at the dock, the mooring cable needs to be safely tied to the quick-release hook on the dock surface to prevent the ship from drifting during loading and unloading. Once the ship drifts to the limit, it will damage the loading and unloading equipment on the dock, causing serious losses and injuries. After the ship is maneuvered and leaves the dock, the cable must be quickly detached from the anchor hook of the release hook to allow the ship to leave the port smoothly. During the entire loading and unloading process, the ship will drift up and down and left and right with the fluctuations of the waves. This requires that the cable must always be safely tied to the anchor hook of the quick-release hook throughout the entire working process and cannot be detached from the anchor hook. At the same time, when the ship leaves, the cable must be quickly detached from the anchor hook.

[0003] Ship release includes the dual functions of safe mooring and quick release. These two functions are the basic performance items of domestic and foreign manufacturers of release hooks. However, when the release hook is mooring, if there is an accident, such as wind and waves exceeding the design value, the floating height of the moored ship is too large, exceeding the design value, it will cause the ship's cable to fall off the anchor hook, causing the ship to leave the safe berthing position, causing damage to the dock loading and unloading equipment or casualties. At present, domestic and foreign quick release hooks have not produced quick release hooks that meet the above two performances. The safe mooring and quick release devices of the quick release hooks cannot take into account the problem of quick release when solving the problem of anti-loosening. We need a device that can meet both safe mooring and quick release to replace the existing equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a dock anti-cable safety hook to solve the problems raised in the above background technology. To achieve the above purpose, the present invention provides the following technical solutions:

[0005] The anti-cable safety hook for the wharf comprises an anchor hook, an anchor hook frame and a buffer device, wherein the buffer device has been fully disclosed by the applicant in the patent application number: 201020225879.7, which can be consulted at any time, and the applicant will not repeat it here. The anchor hook is movably connected to the anchor hook frame through a rotating shaft, and a locking hook mechanism and a unhooking mechanism are also provided in the anchor hook frame. The locking hook mechanism and the unhooking mechanism have been fully disclosed by the applicant in the patent application number: 201020226124.9, which can be consulted at any time. It is installed on the anchor hook frame for resetting the anchor hook. In order to facilitate mooring and unmooring, an anti-cable-unmooring device is provided on the left or right side of the anchor hook frame. The anti-cable-unmooring device includes a stopper rod, a shaft sleeve and a spring, wherein a cylindrical groove is provided at the lower part of the stopper rod, a spring is provided in the cylindrical groove, a stopper pin is provided on one side of the stopper rod, an "L"-shaped stopper groove is provided on the shaft sleeve, the stopper pin is engaged in the "L"-shaped stopper groove and moves. After the stopper rod is fixed, it is close to the hook head of the anchor hook, and a cable hole is formed between the stopper rod and the head of the anchor hook, wherein the stopper rod is cylindrical in shape and the upper part of the stopper rod is a bent structure.

[0006] Preferably: in order to prevent the equipment from rusting and affecting its use, the baffle rod and the shaft sleeve are coated with anti-rust paint. In order to prevent the baffle rod from blocking the rotation of the anchor hook, the baffle rod is fixed to ensure a distance of more than 5mm from the hook back of the anchor hook, and the shaft sleeve is welded to the anchor hook frame.

[0007] Preferably, in order to increase the stability of the anti-dropping device, the material of the blocking rod and the shaft sleeve is a metal material or an alloy material.

[0008] The invention has the following advantages: Based on many years of design and production technology of quick-release hooks and rich field use experience, our company has developed and designed a device to prevent the accidental detachment of ship cables. This device ensures that the cable will not be accidentally detached on the basis of ensuring safe mooring and quick release. This device is installed on the side of the hook frame of the quick-release hook. The structural design is simple and reasonable, the production cost is low, and the operation is flexible and convenient. It has been well evaluated after being used on the dock site.

[0016] Example 1

[0017] like Figures 1 to 7 As shown:

[0018] The anti-cable safety hook comprises an anchor hook 1, an anchor hook frame 3 and a buffer device 5. The anchor hook 1 is movably connected to the anchor hook frame 3 through a rotating shaft 2. The anchor hook frame 3 is also provided with a hook locking mechanism and a hook release mechanism. The buffer device 5 is installed on the anchor hook frame 3. The anti-cable device is characterized in that an anti-cable device is provided on the left or right side of the anchor hook frame 3. The anti-cable device comprises a blocking rod 4-1, a shaft sleeve 4-2 and a spring 4-3, wherein a cylindrical groove 4-1-1 is provided at the lower part of the blocking rod 4-1, a spring 4-3 is provided in the cylindrical groove 4-1-1, and the blocking rod A stop pin 4-6 is provided on one side of 4-1, and an "L"-shaped stop groove 4-5 is opened on the sleeve 4-2, and the stop pin 4-6 is engaged in the "L"-shaped stop groove 4-5. After the stop rod 4-1 is fixed, it is close to the hook head of the anchor hook 1, and a cable hole is formed between the stop rod 4-1 and the anchor hook 1, and the cable hole is used for the cable to pass through, wherein the stop rod 4-1 is cylindrical in shape and the upper part of the stop rod 4-1 is a bent structure, the stop rod 4-1 and the sleeve 4-2 are coated with anti-rust paint, and the material of the stop rod 4-1 and the sleeve 4-2 is metal material or alloy material.

[0019] The working principle of the present invention is as follows: a sleeve 4-2 is welded to the side plate of the anchor hook frame 3, a spring 4-3 is installed in the sleeve 4-2, the other end of the spring 4-3 is installed in the cylindrical groove 4-1-1 of the stop rod 4-1, and a stop pin 4-6 is fixed on the stop rod 4-1. When the dock quick-release hook is safely moored, the stop rod 4-1 of the anti-accidental cable release device fits tightly with the hook head of the anchor hook 1, and the stop pin 4-6 on the stop rod 4-1 is inserted into the highest point of the "L"-shaped stop groove 4-5 of the sleeve 4-2 under the elastic force of the spring 4-3, so that the stop rod 4-1 cannot rotate, and there is no gap between the stop rod 4-1 and the anchor hook, so the cable cannot be released. The process of mooring: manually press the stopper lever 4-1 to the lowest point of the "L"-shaped stopper groove 4-5, and then rotate it to the right, so that there is enough space between the stopper lever 4-1 and the anchor hook 1 for the cable to pass through to achieve mooring. After the cable is hung in the hook groove of the anchor hook 1, rotate the stopper lever 4-1 again. The stopper pin 4-6 on the stopper lever 4-1 is inserted into the highest point of the "L"-shaped stopper groove 4-5 of the shaft sleeve 4-2 under the elastic force of the spring 4-3 and fixed, thereby realizing the function of preventing accidental cable release.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
