Embodiment

[0026] Such as Figure 1-4 As shown in the figure, a non-standard wear-resistant stop block is provided for a chain catch device, including a chain catcher 13, and a roller shaft 9 is connected to the top of the chain catcher 13 through a support, and a roller 6 is mounted on the roller shaft 9. , one side of the roller shaft 9 is connected with a balance weight 2 through a support, and the balance weight 2 is connected with the new stop block 14 through a rotating pin shaft 7, and the other end of the new stop block 14 is equipped with a positioning pin Axis 8.

[0027] The material of the new stop block 14 is wear-resistant high-alloy structural steel, and the casting is changed to steel plate flame cutting, which can effectively slow down the wear of the stop block; at the contact position of the anchor chain and the new stop block 14, drill a small hole and then The polymer wear-resistant material is injected, and the polymer wear-resistant material has the advantage of a...

Abstract

The invention discloses a non-standard wear-resisting stop block chain feeding and pulling device, which comprises a chain stopper, wherein a roller shaft is connected to the upper portion of the chain stopper through a supporting piece; a roller is assembled on the roller shaft; a balance block is connected to one side of the roller shaft through the supporting piece; the balance block is connected with a novel stop block through a rotary pin shaft; and a positioning pin shaft is installed at the other end of the novel stop block. The end face of one side of the novel stop block of the deviceadopts a U-shaped ring surface design and is obviously increased in contact area, therefore, the abrasion of the stop block is reduced. In addition, a chain guide groove is additionally formed in therear part of the U-shaped ring surface; the limiting function is achieved, a motion space is provided for the vertical chain ring, the novel stop block does not need to be opened during anchor weighing, and only the positioning pin shaft needs to be moved away. Thus, operation is convenient, and in the anchor weighing process, if the anchor windlass is overloaded, a chain disengaging phenomenon occurs. Therefore, the novel stop block is not opened at the moment, an anchor chain can be effectively clamped, and therefore the anchor windlass is protected.

Description

technical field [0001] The invention relates to a non-standard wear-resisting stop block feeder chain device, which belongs to the field of ship engineering Background technique [0002] The chain stopper, also known as the chain stopper or the anchor chain stopper, refers to a special device for holding or clamping the anchor chain. It is fixed between the windlass and the chain barrel, separated from the chain wheel, and bears the pulling force of the anchor and chain during anchoring and mooring, so that it will not be transmitted to the chain wheel. [0003] The principle of the traditional chain stopper is that the roller rotates around the roller shaft, and the anchor chain moves with the roller. Welded to the deck of the ship. Since the vertical chain link is in point contact with the stop block, a large stress concentration will be generated, and when the anchor chain is retracted, the anchor chain and the stop block will collide. After a period of use, the contact...
