Description

Chain-pulling device with non-standard wear-resistant stop block

Technical Field

The utility model relates to a chain device of pulling for chain of nonstandard wear-resisting stop block belongs to the ship engineering field

Background

The chain stopper is also called a chain stopper or an anchor chain stopper, and is a special device for stopping or clamping an anchor chain. The anchor chain wheel is fixed between the anchor machine and the anchor chain cylinder, is separated from the anchor chain wheel, and bears the tension of the anchor and the anchor chain when the anchor is retracted and anchored, so that the tension is not transmitted to the anchor chain wheel.

The principle of the traditional chain stopper is that a roller rotates around a roller shaft, an anchor chain moves along with the roller, a stop block blocks a vertical chain ring on the roller to play a role in chain stopping, the stop block transmits force to a body, and the body is directly welded on a ship deck. The vertical chain ring is in point contact with the stop block, so that large stress concentration can be generated, the anchor chain and the stop block are collided when the anchor chain is retracted and released, the contact surface of the stop block and the anchor chain, the positioning pin shaft and the rotating pin shaft can be obviously abraded after one-section use, when the abrasion exceeds a certain degree, the stop block and the pin shaft can be broken due to huge gripping force generated by the anchor and the anchor chain, the chain stopper can be skipped to directly transmit the force to the anchor machine, the anchor winch is not heavy, the safety performance of a ship is seriously affected, and subsequently, high maintenance cost can be generated.

SUMMERY OF THE UTILITY MODEL

The utility model provides a non-standard wear-resisting stop block is used for overcoming the defect that the contact surface of prior art stop block and anchor chain easily weares and teares for chain drag chain device.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model discloses a chain device that pulls is given to nonstandard wear-resisting stopper, including the chain stopper, chain stopper top is connected with the roller shaft through support piece, be equipped with the gyro wheel on the roller shaft, one side of roller shaft is connected with the balancing piece through support piece, the balancing piece passes through rotatory round pin hub connection with novel stopper, the other end of novel stopper is equipped with the locating pin axle.

Furthermore, the novel stop block is made of wear-resistant high-alloy structural steel, and the casting is changed into steel plate flame cutting, so that the abrasion of the stop block can be effectively reduced.

Furthermore, the end face of one side of the novel stop block adopts a U-shaped annular surface design, so that the contact area is obviously increased, and the abrasion of the stop block is greatly reduced.

Furthermore, at the contact position of the anchor chain and the novel stop block, a small hole is drilled and then a high-molecular wear-resistant material is injected, and the high-molecular wear-resistant material has the advantage of high friction coefficient.

Furthermore, a chain guide groove is formed in the rear of the U-shaped ring surface of the novel stop block, so that the swinging of an anchor chain can be effectively limited when the anchor chain is anchored, and the guide effect on a vertical chain ring can be achieved when the anchor chain is anchored.

The utility model discloses the beneficial effect who reaches is:

1. the novel stop block is formed by cutting a casting into a steel plate, so that the casting defects are reduced, and the manufacturing period of the product is greatly shortened.

2. After the high-strength wear-resistant material is used, the weight of the novel stop block is effectively reduced due to the increase of strength and hardness, so that the weight of the configuration block is reduced, and the cost is greatly reduced.

3. The contact area is increased by the surface contact of the U-shaped ring, the stress concentration is reduced, and the abrasion is slowed down; the acting force is obviously reduced, the force direction is changed, the force arm is reduced, the bending moment of the whole chain stopping block is obviously reduced, the weight of a workpiece is effectively reduced, the size of the whole structure is obviously reduced, the cost is saved, and the space is saved. The reduction of the lateral force slows down the abrasion of the shaft parts, and greatly prolongs the service life of the whole machine.

4. The horizontal chain ring is locked by the U-shaped ring surface, the lateral movement of the vertical chain ring is limited by the chain guide groove, the vibration is reduced, the stability of the equipment is improved, and the comfort of drivers is enhanced.

5. The novel stop block that this device used increases the chain guide groove, not only plays limiting displacement outside, still gives a motion space of perpendicular chain link, need not to open novel stop block when the anchor, only need put aside positioning pin axle can, made things convenient for the operation, when the anchor in-process appears transshipping like the anchor windlass moreover, the chain phenomenon can appear taking off, the stop block was not opened this moment, can effectually block the anchor chain to the anchor windlass has been protected.

6. The device perfectly combines the wear-resistant metal material and the wear-resistant polymer material, and has high strength, high wear resistance and high friction coefficient.
