When the spring towing hook 10 drags the towed ship, the spring towing hook 10 needs to slide along the slideway 200, at the moment, the two limiting pieces 3 are respectively fixed at the two ends of the slideway base 2, so that the spring towing hook 10 is prevented from being separated from the slideway base 2, the deck 20 is prevented from being deformed due to collision of the hook head 105, the maintenance cost of the ship is reduced, the hook head 105 is ensured to swing up and down smoothly, the rope can be separated from the spring towing hook 10 in time, the towed ship can be separated from the towed ship in time, the towing ship can be ensured to carry out subsequent towing work as soon as possible, the efficiency is improved, and meanwhile, the safety of the towed ship is also protected in emergency. When the spring towing hook 10 does not need to drag the towed ship, the spring towing hook 10 does not need to slide along the slideway 200, at this time, the two limiting pieces 3 are respectively positioned at two sides of the hook body 102 and are abutted with the hook body 102, and the two limiting pieces 3 are both fixed with the slideway base 2, meanwhile, the spring towing hook 10 is prevented from being separated from the slideway base 2, the spring towing hook 10 is prevented from colliding with the limiting pieces 3, and the durability of the limiting pieces 3 is ensured.
It will be appreciated that the stop 3 comprises two side arms 31 and a connecting arm 32 connected between the two side arms 31. When the limiting piece 3 is fixed with the slide seat 2, the two side arms 31 are respectively connected with the two arc plates 22 correspondingly. In this embodiment, the roller frame is located below the connecting arm 32, and the roller 104 is connected to the bottom surface of the end of the roller frame, that is, the end of the roller frame and the roller 104 can pass through the limiting member 3, so that the limiting member 3 directly abuts against the hook 102.
Specifically, the fixing structure includes through holes and fixing members 4, a plurality of through holes are spaced apart along the extending direction of the sliding track 200 on the first plate section, one end of each fixing member 4 passes through the side arm 31 of the corresponding limiting member 3, and the other end of each fixing member 4 selectively passes through any one of the through holes.
In this embodiment, the side arm 31 is provided with a perforation 311, and the fixing member 4 passes through the side arm 31 through the perforation 311. Two through holes 311 are formed in each side arm 31, and a fixing piece 4 is arranged in each through hole 311, namely, each limiting piece 3 is connected with four fixing pieces 4. The structure prevents the limiting piece 3 from rotating around the fixing piece, and ensures the limiting effect of the limiting piece 3 on the hook body 102. In other embodiments, the number of the perforations 311 formed on each side arm 31 can be adaptively adjusted, which is not limited herein.
Four groups of holes are formed in the two arc plates 22, each group of holes comprises two through holes, wherein two groups of holes are located at two ends of the corresponding arc plate 22, the other two groups of holes are located in the middle of the corresponding arc plate 22, and the four groups of holes in the two arc plates 22 are in one-to-one correspondence. When the spring towing hook 10 tows a towed ship, the two limiting pieces 3 are positioned at two ends of the arc-shaped plate 22, and the two through holes 311 on each side arm 31 are opposite to the two through holes of the hole group corresponding to the end part of the arc-shaped plate 22 respectively, so that the four fixing pieces 4 on each limiting piece 3 penetrate through one through hole and one through hole 311 respectively, and the two limiting pieces 3 are fixed at two ends of the slideway base 2. When the spring towing hook 10 is not required to tow a towed ship, the two limiting pieces 3 are positioned in the middle of the arc plate 22, and the two through holes 311 on each side arm 31 are opposite to the two through holes of the hole group corresponding to the middle of the arc plate 22 respectively, so that the four fixing pieces 4 on each limiting piece 3 are respectively penetrated through one through hole and one through hole 311, and the two limiting pieces 3 are fixed in the middle of the slideway base 2.
In this embodiment, when the locating part 3 is fixed on the slide seat 2 through mounting 4, the medial surface of two side arms 31 of locating part 3 is laminated with the arc 22 of slide seat 2 respectively, and the linking arm 32 of locating part 3 is higher than the top of slide seat 2, the interval sets up between linking arm 32 and the top of arc 22 promptly, when guaranteeing the connection stability between locating part 3 and the mounting 4, reduced the area of contact of slide seat 2 and locating part 3, reduced locating part 3 because of the possibility of the deformation of colliding with slide seat 2, further guaranteed supporting component's durability.
Further, the fixing piece 4 is a bolt, one end of the fixing piece 4 passes through the side arm 31 of the limiting piece 3 and is connected with a nut in a threaded manner, and the other end of the fixing piece 4 can be selectively arranged through any through hole and then is provided with a screw head of the bolt. The structure setting has simplified fixed knot structure's structure, and the cost is lower, places the nut in the outside of locating part 3 moreover, and also the instrument such as spanner of being convenient for is screwed up, has guaranteed the spacing effect of locating part 3, prevents that spring tow hook 10 from breaking away from slide seat 2.
The embodiment also provides a ship. In particular, the vessel comprises a spring tow hook 10 and a support assembly for the spring tow hook as described hereinbefore. The ship realizes that the spring towing hook is completely placed on the deck 20, so that the phenomenon that the hook head 105 collides with the edge of the deck 20 and the surface of the deck 20 when swinging up and down is avoided, the deck 20 is prevented from being collided and deformed by the hook head 105, and the maintenance cost of the ship is reduced.
