Description

Knife switch type chain making device

Technical Field

The invention relates to a ship anchor chain technology.

Background

Knife chain brake is widely used for middle and large ocean vessels, and is used for transmitting the tensile force generated by anchors and anchor chains to the hull so as to lighten the load of the anchor machine and protect the anchor machine. The ship can bear the gravity and inertia force of the anchor when sailing. Because the anchor chains are all made of metal, deformation can occur after long-term tension, namely the length of the chain links of the anchor chains is increased, in which case, if the anchor is still tightened to fit the hull, the positions of the chain links of the anchor before deformation will move towards the anchor machine, namely the direction of tightening the anchor is displaced more or less. Gaps can also be created in the chain that is originally attached to the blade, in which case the chain guard will lose its intended function. The position where the chain stopper will be installed when used on a new vessel will be determined by means of high accuracy measurements. However, during long-term use thereafter, if the position of the chain stopper does not match the position of the chain link and deforms to a prescribed extent, the vessel must stop working to the dock-adjusting chain stopper position.

Detailed Description

The side surface is provided with screw holes ii-30, and the two sides of the base 16 of the base with the chain guide groove 25 on the upper surface are respectively fixed with the base inner plate 13 and the right-angled triangle longitudinal adjusting base 11. The chain guide channel 25 allows for adjustment of the chains 26 such that the chains 26 engage vertically with each other and the chains are approximately perpendicular to the upper surface of the foundation base 16. The inclined sides of the longitudinal adjustment base 11 are respectively provided with a step structure i, and the vertical inner groove 20 penetrates through the step structure i from top to bottom. The height through which this takes place depends on the amount of downward displacement required when the longitudinal adjustment slide 21 is adjusted to its maximum extent. The maximum longitudinal adjustment means: the longitudinal adjustment slide 21 directly bears the load brought by the anchor chain 26 through the knife switch 1, along with the increase of the longitudinal adjustment distance, the longitudinal adjustment slide 21 moves downwards, the height of each downwards movement is one step, and when the longitudinal adjustment slide 21 moves downwards to the upper bottom of the vertical inner groove 20 in the longitudinal adjustment base 11 when the T-shaped head 20 of the transmission frame 19 is positioned, the maximum limit of the longitudinal adjustment is reached. The maximum setting depends on the desired range of adjustment of chain 26.

A right triangular longitudinal adjustment slider 21 provided with a step structure ii is placed on the longitudinal adjustment base 11, the step structure ii being opposite to the step structure i in the same direction as the shape. The inside of the longitudinal adjustment slide 21 is provided with a T-shaped groove ii-32, the T-shaped groove ii-32 is matched with the T-shaped plug 29 of the transmission frame 19, the lower surface of the T-shaped groove is provided with steps, the length of each step is the accuracy of longitudinal adjustment, the steps of the steps are ensured to ensure that the sum of the lengths of all the steps is greater than or equal to the maximum length of the longitudinal adjustment, the lengths of each step are equal, and the heights of each step of other steps except the step at the top end are equal. The height of the topmost end is larger than the height of other steps, the height of the topmost end is 1.3-1.6 times of the height of other steps, the optimal value is 1.4 times, when the height is adjusted to the maximum limit, the topmost end of the longitudinal adjustment sliding block 21 is contacted with the knife 1, and the upper surface of the longitudinal adjustment sliding block 21 is slightly higher than the upper surface of the knife 1. The maximum length of the longitudinal adjustment is the longitudinal distance of the longitudinal adjustment slider 21 when moving from the initial position R to S, which is not less than the sum of the lengths of one horizontal anchor link and one vertical anchor link.

The longitudinal adjustment slider 21 is directly subjected to the pressure F exerted by the anchor chain 26, which is the majority of the load exerted by the anchor chain 26 via the blade 1, and is ultimately borne by the longitudinal adjustment base 11 and the base 16 of the foot rather than by the adjustment mechanism consisting of the transmission frame 19 and the longitudinal adjustment screw 17, which is responsible for the longitudinal adjustment. Vessels of different tonnage can be equipped with anchors of different weights, varying from a few tons to a few tens of tons, the load carried by the chain stopper mainly comes from the weight of the anchors and the weight of the anchor chain 26 from the chain stopper to the anchor end, and inertial forces at the anchor end are generated when the hull is rocked by waves during sailing. If the load is applied directly to the adjustment mechanism, the longitudinal adjustment threads carrying the load will deform or even break due to the long term application of the load. The adjustment precision of the longitudinal adjustment slider 21 is the length of a unit step, the length of the unit step is equal to the maximum interval of transverse adjustment, namely, when the gap between the anchor chain 26 and the knife switch 1 after deformation is tightened is smaller than the length of the unit step, the longitudinal adjustment and the transverse adjustment are performed when the gap exceeds the length of the unit step but is smaller than twice the length of the unit step, the longitudinal adjustment is that the longitudinal adjustment screw 17 is rotated to drive the transmission frame 19 to push the longitudinal adjustment slider 21 for one unit step length, and then the transverse adjustment is used for fine adjustment, so that the residual gap is eliminated.

The driving longitudinal adjustment slider 21 is an adjustment mechanism composed of a transmission frame 19 and a longitudinal adjustment screw 17. The two front ends of the transmission frame 19 with the U-shaped structure are respectively provided with a T-shaped plug 29, and the middle part of the beam which extends downwards from the rear part is provided with a transmission frame structure hole 24. The end part of the cross beam extending downwards from the rear part of the transmission frame 19 is connected with the longitudinal beam of the transmission frame 19 to form a right triangle, and when the transmission frame 19 pushes the longitudinal adjustment sliding block 21 to adjust to the maximum extent of longitudinal adjustment, the vertex angle of the right triangle at the longitudinal beam just reaches but does not enter the vertical inner groove 20 of the longitudinal adjustment base 11. The right triangle configuration here makes the rear part of the transmission frame 19 stronger by virtue of its geometrical characteristics. The trailing end of the longitudinal adjustment screw 17 provided with the stop projection 39 passes through the drive frame structural hole 24 and is axially stopped by the retainer ring 18 and the leading end is inserted into the screw hole ii-30 of the end face of the base 16 of the pedestal. When the longitudinal adjusting screw 17 is rotated to push the longitudinal adjusting slide block 21, the retainer ring 18 can transmit the pushing force of the longitudinal adjusting screw 17, when the longitudinal adjusting slide block 21 is maximally adjusted to the initial state by the longitudinal adjustment, the longitudinal adjusting screw 17 is reversely rotated to pull the transmission frame 19 back to the initial state, and at the moment, the limiting protrusion 39 provides the pulling force. Description of the assembly process of the longitudinal adjustment screw 17 and the transmission frame 19: the rod part of the longitudinal adjusting screw 17 is matched with the transmission frame structure hole 24 by a shaft hole, the outer diameter of the retainer ring 18 is the same as the outer diameter of the transmission frame structure hole 24, the longitudinal adjusting screw 17 is inserted into the transmission frame structure hole 24 until the retainer ring 18 is attached to the transmission frame structure hole 24, then the limiting bulge 39 is sleeved on the longitudinal adjusting screw 17, and the limiting bulge 39 is welded on the longitudinal adjusting screw 17 when the limiting bulge 39 is attached to the other surface of the transmission frame structure hole 24. The transmission frame structure holes 24 are limited in front and back. The tail end of the longitudinal adjusting screw 17 is fixed with a longitudinal rotating handle i-37-1. The two T-shaped plugs 29 of the transmission frame 19 are respectively embedded into the T-shaped grooves ii-32 of the two longitudinal adjustment slide blocks 21 through the vertical inner grooves 20 on the longitudinal adjustment base 11. When the longitudinal adjustment is performed, each time a unit step length is adjusted, the longitudinal adjustment sliding block 21 moves up and down by a unit step height on the longitudinal adjustment base 11, and the T-shaped grooves ii-32 and the T-shaped plug 29 are relatively displaced, wherein the T-shaped plug 29 does not move vertically, and the T-shaped grooves ii-32 vertically and downwards move based on the T-shaped plug 29.

An L-shaped base outer plate ii-12-2 is fixed outside the longitudinal adjusting base 11 on one side, a transverse T-shaped groove i-15 is arranged on the L-shaped base outer plate ii-12-2, a screw hole iii-34 is arranged on the side face of the plug 36, an arc surface 33 is arranged at one end of the plug, the cross section of the plug is matched with the transverse T-shaped groove i-15, and a sliding fit gap is formed between the contact surfaces of the plug 36 and the T-shaped groove i-15. In the first step of assembly, the round stop 38 of the transverse adjusting screw 7 assembled with the transmission block 6 is fitted along the T-shaped groove i-15. In a second step, plug 36 is installed into base outer panel ii-12-2. Third, screw is screwed into screw hole iii-34 to fix plug 36 to T-shaped groove i-15, forming longitudinal slot. The mechanism for longitudinal adjustment is provided with a longitudinal adjustment slide block 21, a knife 1, a transmission block 6 and a transverse adjustment screw 7. The longitudinal slot provides a longitudinal sliding track for the lateral adjustment screw 7 when the blade 1 is moved longitudinally. The length of the longitudinal long hole is equal to the diameter of the longitudinal adjustment section plus the transverse adjustment screw 7.

The support frame 10 provided with a plurality of parallel slide long holes 23 is fixed to the outer side of the base outer plate ii-12-2. A T-shaped chute 14 with a cross section is arranged below the transmission block 6 with a screw hole i-22 in the middle, the bar i-8-1 and the bar ii-8-2 are mutually vertically fixed to form an upper sliding block, and the difference value between the longitudinal length of the bar ii-8-2 and the long hole 23 of the chute is smaller than the width GH of the transmission block 6. The bar iii-9-1 and the bar v-9-3 are mutually parallel and fixed into a lower slide block through the middle vertical bar iv-9-2. The lower slide block is inserted into a slide way slot hole 23 on the supporting frame 10, a sliding fit clearance is formed between the lower slide block and the slide way slot hole 23, the slide way slot hole 23 provides a sliding track for the slide block, the sliding direction is transverse, a sliding fit clearance is formed between the upper slide block and a T-shaped chute 14 of the transmission block 6, the sliding track is provided for the upper slide block, and the sliding direction is longitudinal. Each slide slot 23 has a slide block therein, and when the slide blocks are aligned in the longitudinal direction, the length of the slide blocks is not smaller than the longitudinal adjustment section and is the sum of the longitudinal adjustment section and the width GH of the transmission block 6. The spacing h of the slide slots 23 should be no less than the length of the bar ii-8-2 minus the width g of the slide slots 23 to ensure that the bar ii-8-2 has sufficient space on the support frame 10 but should not be greater than the width GH of the drive block 6. If the distance h exceeds the width GH of the driving block 6, the driving block 6 will be separated from the bar i-8-1 at a certain point in the process of moving from one slide slot 23 to the other slide slot 23. The number of the plurality of transverse slide slots 23 on the support frame 10 is set according to the length PQ from the front side edge of the first slide slot to the rear side edge of the last slide slot being greater than the sum of the movement range RS of the longitudinal adjustment slide 21 and the width GH of the single driving block 6, so as to ensure that sufficient space is available for movement on the support frame 10 when the driving block 6 is displaced longitudinally with the knife 1. When the transmission block 6 moves longitudinally, at least one bar i-8-1 is arranged in the T-shaped chute 14, and the width of the bar i-8-1 is consistent with the width g of the single slide long hole 23, so that the sum of the distance h between two adjacent transverse slide long holes 23 and the width g of the single slide long hole 23 is not larger than the width GH of the transmission block 6.

One end of the transverse adjusting screw 7, which is fixedly provided with a round stop block 38, is inserted into a longitudinal long hole on the base outer plate ii-12-2, the other end of the transverse adjusting screw passes through a screw hole i-22 in the middle of the transmission block 6 to be connected with a transverse screw rotating handle ii-37-2, and a sliding fit clearance is formed between the outer edge of the round stop block 38 and a transverse T-shaped groove i-15 at the longitudinal long hole. The rod parts of the transverse adjusting screw rods 7 are all threaded, and when the transverse adjusting screw rods 7 are rotated, the transmission blocks 6 generate transverse displacement, so that the knife switch 1 is driven to transversely move, and transverse adjustment is realized.

The outside of the other side longitudinal adjustment base 11 is fixed with a U-shaped base outer plate i-12-1, one upper end of the base outer plate i-12-1 is provided with a pin 40 connected in series with one end of the bumper 28, and the other end of the bumper 28 is locked by a safety pin 27 at the other upper end of the base outer plate i-12-1. The blade 1 is flattened and the safety lever 28 and the fixed blade 1 prevent it from lifting up due to the moment provided by the counterweight 3 or the pitching of the vessel.

The narrow end of the lock blade 1 with the inclined plane 2 at one side is fixed with the lock blade handle 4, and the wide end is fixed with the balance weight 3 through the connecting plate 35, so that the force required by a shipman when lifting or dropping the lock blade 1 is reduced. The plane of the blade 1 forms an obtuse angle with the cross section between the connection plate 35. The counter weight 3 can balance moment when the lock blade 1 is put on or lifted, and reduces the force required by a shipman to lift or drop the lock blade 1. A hinge is arranged between the connecting plate 35 and the transmission block 6. The hinge in this case consists of a fixing plate 5 fastened to the upper surface of the driving block 6 and provided with a fixing plate recess 41 and a through hole 42, and a plugboard 45 provided with plugboard protrusions 43 and screw holes iv-44, and is fastened to the screw holes iv-44 by screws through the through hole 42. The fixing plate 5 and the insert plate 45 are provided at one end with hinge holes through which the hinge shaft 31 passes.

The working principle of the knife chain making device is as follows: when the chain stopper stops the anchor chain 26, the knife 1 is put flat, the safety bar 28 is mounted on the base outer plate i-12-1, the safety bar 28 can be fixed by inserting the safety pin 27, and the safety bar 28 can prevent the knife 1 from being lifted up due to the shaking of the ship and the acting force of the counter weight 3 when being put flat. Knife 1 is positioned to clamp the vertical chain at the position where the vertical chain and the horizontal chain of the anchor chain 26 are meshed, so that the anchor chain 26 cannot move under the condition of being subjected to F force, and the displacement of the anchor chain 26 is restrained. When the anchor chain 26 is deformed, i.e. some single-link chain rings are lengthened, if the anchor chain 26 is tightened again, the vertical chain originally attached to the knife 1 cannot be attached to the knife 1, and the chain making device cannot function, and at this time, the knife 1 can be moved transversely by using the transverse adjusting device or the knife 1 can be moved longitudinally by using the longitudinal adjusting device to attach to the anchor chain 26 again. When the anchor chain 26 is deformed, if the displacement distance of the vertical chain attached to the knife 1 is smaller than the length of a single step of the longitudinal adjustment sliding block 21, the knife 1 can be adjusted by the transverse adjustment screw 7 to move transversely until the knife 1 is attached to the vertical chain. When the displacement of the vertical chain attached to the knife 1 is larger than the length of a single step of the longitudinal adjusting slide block 21, the knife 1 can be adjusted by the longitudinal adjusting screw 17 to longitudinally move by the distance of the single step, and at the moment, the distance between the knife 1 and the vertical chain is smaller than the length of the single step of the longitudinal adjusting slide block 21, the knife 1 can be adjusted by the transverse adjusting screw 7 until the knife 1 is attached to the vertical chain. In summary, when the degree of deformation of the anchor chain 26 is small due to the transverse adjustment, and when the displacement distance between the anchor chain 26 and the vertical chain attached to the guillotine 1 is an integral multiple of the length of a single step of the longitudinal adjustment slider 21 after the deformation of the anchor chain 26 is achieved due to the longitudinal adjustment, the use of the transverse adjustment and the longitudinal adjustment together can be realized in an adjustable interval, and the anchor chain 26 can be deformed at will.

The invention adopting the technical scheme has obvious technical and economic benefits. The deformation of the anchor chain is caused by the fact that the anchor is subjected to a continuous force for a long time, and its deformation amount is about several months to the extent that an adjustment operation is required. If the vessel is sailing in rough sea for a long period of time or is turned or decelerated with anchors frequently over a period of time, the deformation of the anchor chain may be accelerated. The present invention can reduce the accuracy required for its installation position when the chain stopper is installed on a ship. The required precision of the installation position is required. The required precision of the installation position is required. The anchor chain can be put in a tightened state again by simply adjusting the knife switch when the anchor chain is in any deformation. Compared with an unregulated state, the free swing of the anchor in an untruncated state caused by swinging can be obviously reduced to bring additional load to the anchor chain when the ship sails, so that the further deformation of the anchor chain is effectively avoided, and the service life of the anchor chain is effectively prolonged. When the deformation amount of the anchor chain is large, if the anchor chain is not tightened, further damage is brought, the swing amplitude of the anchor is further increased compared with the case that the deformation amount is small when the ship sails, the anchor in swing possibly collides with the bow hull, and the hull is damaged when the situation is serious. Because the chain stopper can be timely adjusted for the anchor chain under any deformation amount, the larger loss of the anchor chain when the anchor chain is in a larger deformation amount can be avoided. The commercial ship with huge carrying tonnage is a main transport tool for pushing international trade, and the chain brake can reduce the times of docking adjustment of the ship caused by deformation of the anchor chain, reduce the loss caused by shutdown of the ship and reduce the cost for maintaining and adjusting the anchor chain.
