Abstract

The utility model relates to an anchor drop test fall off buckle, which is innovative in comprising a hanging buckle; a hook is connected with the bottom of the hanging buckle through a first hinge pin; the gravity centre of the hook, on which an anchor is hung, is positioned on the opening side of the hook; a lock hook plate, the middle of which is connected with the hanging buckle through a second hinge pin, is installed at the back of the hanging buckle; the lower end of the lock hook plate is propped against the tail end of the hook to prevent the first hinge pin from rotating; and an anchor line for pulling the lock hook plate to rotate around the second hinge pin to separate the lock hook plate from the tail end of the hook is connected with the upper end of the lock hook plate. The anchor drop test fall off buckle has the advantages that a shackle of the anchor is sheathed on the hook at the bottom of the hanging buckle during testing, the anchor is lifted in the air through a navigation crane, the anchor line is pulled to be propped against the lock hook plate at the tail end of the hook to enable the lock hook plate to be separated from the hook, and the hook, the gravity centre of which is positioned on the opening side, rotates around the first hinge pin, so as to enable the anchor to drop off from the air, so that the drop test is realized. A return spring can pull the lock hook plate to automatically return after the anchor drops off.

Description

A kind of anchor fall-down test button that comes off

Technical field

The utility model relates to a kind of anchor, particularly a kind of button that comes off that is used for anchor is carried out fall-down test.

Background technology

Anchor is the critical piece of anchoring and mooring system, and it is can produce grip by engaging-in subsoil after being thrown in the water, and makes ship be docked in the utensil in a certain waters by anchor chain.Anchor needs it to carry out fall-down test in process of production under aerial throwing, to guarantee the quality of product.

The utility model content

The technical problems to be solved in the utility model provides a kind of button that comes off that is used for anchor is carried out fall-down test.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of anchor fall-down test button that comes off, its innovative point is: comprise that one buckles, the bottom that buckles is connected with hook by first bearing pin, and the center of gravity that this hook hangs up after the anchor is positioned at the hook open side; One middle part is installed at the back that buckles and buckles the lock crook plate that is connected by second bearing pin, the lock crook plate lower end props up the hook end and prevents around the rotation of first bearing pin, and the lock crook plate upper end is connected with the pulling lock crook plate and around the rotation of second bearing pin lock crook plate is broken away from the terminal drag-line of hook.

Further, be connected with retracing spring on the described lock crook plate and between buckling.

Advantage of the present utility model is: during test, with the shackle casing of anchor on the hook that buckles the bottom, hang by boat anchor is raised up in the air, the pulling drag-line, prop up the terminal lock crook plate of hook and break away from hook, the hook that center of gravity is positioned at open side rotates around first bearing pin, makes anchor from coming off in the air, realizes fall-down test.Retracing spring can be at the anchor post-tensioning moveable lock hook plate self-return that comes off.

Fig. 1 is the utility model anchor fall-down test button front view that comes off.

Fig. 2 is the utility model anchor fall-down test button side view that comes off.

Embodiment

As shown in Figure 1, 2, comprise and buckle 1, first bearing pin 2, hook 3, lock crook plate 4, second bearing pin 5, drag-line 6.

Above-mentioned 1 the bottom of buckling is connected with hook 3 by first bearing pin 2, and this hook 3 hangs up center of gravity after the anchor and is positioned to hang and reaches 3 open side.Lock crook plate 4 is arranged on and buckles 1 back, its middle part with buckle 1 and be connected by second bearing pin 5, this second bearing pin 5 is vertical with the direction of first bearing pin 2, the lower end of lock crook plate 4 props up the end of hook 3, prevent that it from rotating backward around first bearing pin 2, the upper end of lock crook plate 4 is connected with a drag-line 6, and this drag-line can spur lock crook plate 4 makes lock crook plate 4 break away from hook 3 ends around 5 rotations of second bearing pin, thereby realizes the rotation of hook 3.Lock crook plate 4 upper ends and buckle 1 between be connected with retracing spring 7.

During test, the shackle casing of anchor on the hook 3 that buckles 1 bottom, is hung by boat anchor is raised up in the air, pulling drag-line 6, the lock crook plate 4 that props up hook 3 ends breaks away from hook 3, and center of gravity is positioned at the hook 3 of open side around 2 rotations of first bearing pin, make anchor from coming off in the air, realize fall-down test.

Claims

1. anchor fall-down test button that comes off, it is characterized in that: comprise that one buckles, the bottom that buckles is connected with hook by first bearing pin, and the center of gravity that this hook hangs up after the anchor is positioned at the hook open side; One middle part is installed at the back that buckles and buckles the lock crook plate that is connected by second bearing pin, the lock crook plate lower end props up the hook end and prevents around the rotation of first bearing pin, and the lock crook plate upper end is connected with the pulling lock crook plate and around the rotation of second bearing pin lock crook plate is broken away from the terminal drag-line of hook.

2. the anchor fall-down test according to claim 1 button that comes off is characterized in that: described lock crook plate upper end and buckle between be connected with retracing spring.
