Description
Technical Field
The utility model relates to a protection device, especially a chain anchor equipment protection device belong to chain anchor annex technical field.
Background
When a ship is anchored and parked, one end of the anchor chain is connected with the anchor which is sunk into the water bottom, the other end of the anchor chain is connected with equipment on the ship, and when the ship is impacted and vibrated, the ship and the equipment on the ship are very easy to damage. In order to avoid the above situation, at present, a safety ring having a lower strength than the anchor chain is generally provided at the end of each anchor chain, and when the load applied to the safety ring reaches a certain value, the safety ring is broken, and the whole anchor chain is separated from the ship, thereby protecting the safety of the ship and the equipment on the ship. However, the safety ring must be connected to the end of the anchor chain during the manufacture of the anchor chain, and cannot be adjusted and installed according to actual conditions on site, so that certain limitations exist, and meanwhile, the safety ring cannot meet the connection requirements under some special conditions.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, easy dismounting, wide application range's anchor chain safety device.
The utility model discloses a following technical scheme realizes:
a kind of anchor chain safety device, including a pair of connection combination, several cross pins and several pairs of rubber pads; the pair of connecting combinations are respectively positioned at two sides of the tail ends of the two anchor chains, each pair of connecting combinations comprises two connecting plates and two stud bolts which are arranged side by side, the two stud bolts respectively transversely penetrate through two ends of the two connecting plates, and two ends of the stud bolts are respectively locked through nuts; one ends of the transverse pins sequentially penetrate through the connecting plate on one side of the anchor chain, the tail end ring corresponding to the anchor chain and the connecting plate on the other side of the anchor chain respectively and are locked through fastening nuts; and the rubber pads are respectively sleeved in the middle parts of the transverse pins and positioned on the inner sides of the two connecting plates, and the two sides of the terminal ring of the anchor chain are compressed.
The object of the invention is further achieved by the following technical measures.
In the above-mentioned anchor chain safety device, the stud bolt is provided with a breaking portion at the middle portion thereof.
The above-described anchor chain safety device, wherein the diameter D of the breaking portion is 0.4 to 0.6 times the diameter D of the anchor chain end ring.
In the anchor chain safety device, the anti-rotation gaskets are arranged between the nuts at the two ends of the stud bolt and the connecting plate.
The utility model discloses both ends all link to each other with the anchor chain, simple structure, easy dismounting can adjust the installation according to actual conditions at the scene, and it is very convenient to use, and application range is wide. When the utility model discloses when the load that both ends bore reached the predetermined value, four stud's the rupture portion all broke off to equipment does not receive the damage on protection boats and ships and the ship.
The advantages and features of the invention will be illustrated and explained by the following non-restrictive description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
figure 2 is a bottom view of the anchor chain of figure 1 with the anchor chain removed.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the present invention includes a pair of connecting assemblies 1, two cross pins 2 and two pairs of rubber pads 3. A pair of connection combination 1 is located the terminal both sides of two anchor chains 4 respectively, and every connection combination 1 is including two connecting plates 11 and two stud 12 that set up side by side, totally four connecting plates 11 and four stud 12, and two stud 12 cross the upper end and the lower extreme of two connecting plates 11 respectively, and stud 12's both ends are respectively through nut 13, prevent changeing the locking of gasket 14. The lower ends of the two transverse pins 2 sequentially penetrate through a connecting plate 11 on the upper side of the anchor chain 4, an end ring 41 corresponding to the anchor chain 4 and a connecting plate 11 on the lower side of the anchor chain 4 respectively and are locked through fastening nuts 15, cushion blocks 16 are arranged between the fastening nuts 15, head nuts of the transverse pins 2 and the connecting plate 11, the connection of the device is guaranteed to be stable, and the right ends of the bolts 17 transversely penetrate through the fastening nuts 15 and the lower ends of the transverse pins 2 and are fastened through nuts. Two pairs of rubber pads 3 are respectively sleeved in the middle parts of the two transverse pins 2 and are positioned on the inner sides of the two connecting plates 11, and the two sides of the tail end ring 41 of the anchor chain 4 are tightly pressed. The stud bolt 12 is provided with a breaking portion 121 at a central portion thereof, and a diameter D of the breaking portion 121 is 0.4 to 0.6 times a diameter D of the end ring 41 of the anchor chain 4, where D is 0.4 times D in this embodiment.
As shown in fig. 1, when the two ends of the present invention bear the load in the direction shown in the figure and the load value reaches the predetermined value, the breaking portions 121 of the four stud bolts 12 are broken.
