It will be appreciated that the limiting member 3 comprises two side arms 31 and a connecting arm 32 connected between the two side arms 31. When the limiting member 3 is fixed to the chute base 2, the two side arms 31 are correspondingly connected to the two arc plates 22, respectively. In the 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 provided on the first plate section at intervals along the extending direction of the slide 200, one end of the fixing member 4 passes through the side arm 31 of the limiting member 3, and the other end is selectively inserted into any one of the through holes.
In this embodiment, the side arm 31 is provided with a through hole 311, and the fixing member 4 passes through the side arm 31 through the through hole 311. Two through holes 311 are formed in each side arm 31, and a fixing member 4 is arranged in each through hole 311, that is, each limiting member 3 is connected to four fixing members 4. Due to the structural arrangement, the limiting part 3 is prevented from rotating around the fixing part, and the limiting effect of the limiting part 3 on the hook body 102 is ensured. In other embodiments, the number of the through holes 311 formed in each side arm 31 can be adjusted adaptively, and is not limited herein.
Four groups of hole groups are arranged on the two arc-shaped plates 22, each group of hole groups comprises two through holes, wherein the two groups of hole groups are positioned at two ends of the corresponding arc-shaped plates 22, the other two groups of hole groups are positioned at the middle parts of the corresponding arc-shaped plates 22, and the four groups of hole groups on the two arc-shaped plates 22 are arranged in a one-to-one correspondence manner. When the spring towing hook 10 tows a towed ship, the two limiting members 3 are located at two ends of the arc-shaped plate 22, and the two through holes 311 on each side arm 31 are respectively opposite to the two through holes of the hole group corresponding to the end of the arc-shaped plate 22, so that the four fixing members 4 on each limiting member 3 are respectively inserted into one through hole and one through hole 311, and the two limiting members 3 are fixed at two ends of the slideway base 2. When the spring towing hook 10 does not need to tow the towed ship, the two limiting members 3 are located in the middle of the arc-shaped plate 22, and the two through holes 311 on each side arm 31 are respectively opposite to the two through holes of the hole group corresponding to the middle of the arc-shaped plate 22, so that the four fixing members 4 on each limiting member 3 are respectively inserted into one through hole and one through hole 311, and the two limiting members 3 are fixed in the middle of the slideway base 2.
In this embodiment, when locating part 3 passes through mounting 4 to be fixed on slide seat 2, the medial surface of two side arms 31 of locating part 3 is laminated with slide seat 2's arc 22 respectively, and the linking arm 32 of locating part 3 is higher than slide seat 2's top, the interval sets up between linking arm 32 and the top of arc 22 promptly, when guaranteeing the stability of being connected between locating part 3 and the mounting 4, the area of contact of slide seat 2 with locating part 3 has been reduced, locating part 3 has been reduced because of the possibility of colliding with the deformation with slide seat 2, supporting component's durability has further been guaranteed.
Further, the fixing member 4 is a bolt, one end of the fixing member 4 is connected with a nut through a thread after passing through the side arm 31 of the limiting member 3, and the other end of the fixing member is selectively inserted into any through hole and then provided with a screw head of the bolt. The structure arrangement simplifies the structure of the fixing structure, has lower cost, and arranges the nut at the outer side of the limiting part 3, thereby being convenient for tightening by using tools such as a spanner, ensuring the limiting effect of the limiting part 3 and preventing the spring towing hook 10 from separating from the slideway base 2.
The embodiment also provides a ship. In particular, the vessel comprises a spring tow hook 10 and a support assembly of the spring tow hook as described in the foregoing. The ship realizes that the spring towing hook is completely placed on the deck 20, avoids the hook head 105 from colliding with the edge of the deck 20 and the surface of the deck 20 during the up-and-down swinging, avoids the deck 20 from being collided and deformed by the hook head 105, and reduces the maintenance cost of the ship.
