Detailed Description

Example 1

Referring to fig. 1 and 2, the screw type chain stopper anchor pulling device provided by this embodiment includes a bearing mounting seat 8, a top cover 3, a supporting seat 9, a screw rod 10 and a hand wheel 2, the bearing mounting seat 8 is connected with the top cover 3 through a bolt to form a sealed box body, a radial bearing 5, a rotating shaft 6, a thrust bearing 7 and a sealing ring 4 are mounted in the sealed box body, centers of circles of through holes of various parts in the sealed box body and the sealed box body are in the same straight line, the lower end of the sealed box body is connected with the upper end of the supporting seat 9 through a bolt 12, the screw rod 10 penetrates through the supporting seat 9, the sealed box body and the through holes of the various parts in the sealed box body and is in threaded connection with the rotating shaft 6.

The bearing mounting seat is internally sleeved with a thrust bearing, the thrust bearing is internally sleeved with the lower end of a rotating shaft, and the upper end of the rotating shaft is sleeved in the radial bearing and the sealing ring.

The handle of the hand wheel 2 is connected with the handle 15, and the hand wheel 2 is pulled to rotate by the handle.

The hand wheel 2 drives the rotating shaft 6 to rotate through a key 14 arranged on the rotating shaft 6.

The internal thread on the inner wall of the through hole of the rotating shaft 8 is in threaded connection with the external thread on the surface of the screw rod 10. The lifting of the screw rod and the hook is realized in the rotating process.

The bottom of the screw 10 is provided with a hook 11.

One side of the support seat 9 is connected with a mounting plate 13 through a bolt.

As shown in figure 3, the device is arranged at the head part of the chain stopper, and the anchor chain is connected with the hook through a steel wire rope. When the device is used, the hand wheel is rotated to drive the screw rod and the hook to ascend, and the hook pulls the steel wire rope, so that the aim of tightening and fixing the ship anchor is fulfilled.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
