Description

A Calculation Method for the Clearance of Brake Limiting Device of Anchor Equipment

technical field

The invention belongs to the technical field of ship equipment, and in particular relates to a calculation method for the gap of a brake limit device of anchor equipment.

Background technique

The anchor equipment is an important equipment of the ship, the brake system is a necessary component system of the anchor equipment, and the brake limit device is an important part of the brake system. Anchor equipment is used for laying and receiving anchor chains. The basic requirements are that the anchor chains can be loosened when the anchor chains need to be released, can be braked when the anchor chains need to be braked, and can be winched back with the windlass when they need to be retracted. The device that controls the loosening or braking of the anchor chain of the anchor device is the braking system of the anchor device.

The brake system of the anchor equipment includes a brake band, an adjustment device and a brake limiter. The brake band is used to be sleeved on the brake hub. The brake band includes an upper brake pad and a lower brake pad. Both the upper brake pad and the lower brake pad have relative settings. The first end and the second end of the upper brake pad and the first end of the lower brake pad are connected through the first rotating shaft, and the second end of the upper brake pad is connected to the brake connected to the hull through the second rotating shaft. On the support frame, the brake limiting device is arranged under the lower brake pad, and there is a gap between it and the lower brake pad, and the adjusting device is connected with the second end of the lower brake pad, and is used to pull or push the lower brake pad, so that the brake The belt tightens or loosens the brake hub to realize the loosening or braking of the anchor chain of the control anchor equipment.

The clearance between the brake stop and the lower brake pad is an important factor in the proper functioning of the brake system, the condition of the brake band wear and the service life of the brake band. In actual use, when the linkage device pushes the lower brake pad, the lower brake pad will be pushed away from the brake hub first. Due to the lifting and restriction of the positioning device, the gap between the lower brake pad and the brake hub will be large, and the upper brake pad is still attached to the brake hub due to gravity, resulting in friction between the upper brake pad and the brake hub when the brake belt is released. The force is still relatively large. In severe cases, the anchor of the anchor device cannot be thrown out by gravity when the brake band is completely loosened. Even if it can be thrown out or sent out with the anchor device, the upper brake pad will wear out quickly due to long-term local friction. As a result, the service life of the upper brake pad is reduced. If the gap of the brake limiter is too small, when the lower brake pad is limited by the brake limiter before it is fully disengaged, the lower brake pad will also wear faster due to long-term local friction. Therefore, the size of the gap between the brake limiting device and the lower brake pad is directly related to the use effect and service life of the braking system of the anchor equipment.

At present, when the crew installs or adjusts the clearance of the brake limit device, it mainly relies on personal experience, which is time-consuming and laborious, and there are very few crew members who have experience in adjusting the clearance of the brake limit device. As a result, many ships are affected by the inappropriate clearance of the brake limit device. The normal use of the equipment, and even some ships caused accidents due to improper setting of the clearance of the limit device.

A calculation method for the clearance of the brake limit device of anchor equipment, which is applied to the brake system of the anchor equipment. The brake system includes a brake band 1, an adjustment device and a brake limit device 2. The brake band 1 is used to be sleeved on the brake hub 3 , the brake band 1 includes an upper brake pad and a lower brake pad, the upper brake pad and the lower brake pad all have oppositely arranged first ends and second ends, between the first end of the upper brake pad and the first end of the lower brake pad Connected by the first rotating shaft, the second end of the upper brake pad is connected to the brake support frame connected with the hull through the second rotating shaft, and the brake limiter 2 is arranged below the lower brake pad, and there is a gap between it and the lower brake pad , the adjustment device is connected with the second end of the lower brake pad, and is used to pull or push the lower brake pad, so that the brake band 1 is tightly held or the brake hub 3 is loosened, and the anchor chain of the control anchor equipment is loosened or braked.

The calculation method of the clearance of the brake limiter of the anchor equipment of the present invention comprises the following steps:

S1. Push the second end of the lower brake pad through the adjustment device, loosen the brake system to the state where the anchor equipment can break down, and obtain the moving distance of the second end of the lower brake pad pushed by the adjustment device;

S2. Calculate the change in circumference of the circle where the brake band 1 is located according to the obtained moving distance of the second end of the lower brake pad;

S3. Calculate the gap between the brake limiter 2 and the lower brake pad according to the change in the circumference of the circle where the brake band 1 is located

In the above step S1, when the brake system brakes the anchor equipment tightly, the brake pad is pushed down by the adjustment device until the brake band 1 loosens the brake hub 3, and when the anchor equipment can throw the anchor chain, the adjustment device is obtained. Push the moving distance of the second end of the lower brake pad, and the moving distance of the second end of the lower brake pad is the amount of change in the arc length of the brake band 1 from when the brake hub 3 is held tightly to when the brake hub 3 is released.

Further, the adjustment device includes an L-shaped linkage 4 and a drive assembly. The L-shaped linkage 4 includes a long end 41 and a short end 42. The connection between the short end 42 and the long end 41 is connected to the brake support frame through a third rotating shaft. The end of the short end 42 away from the long end 41 is the third end, the third end is connected to the second end of the lower brake pad, the end of the long end 41 away from the short end 42 is the fourth end, and the driving assembly is connected to the fourth end, Move up and down on the fourth end of the drive. The driving assembly drives the fourth end of the long end 41 to move up and down, thereby driving the third end of the short end 42 to pull or push the second end of the lower brake pad, so that the brake band 1 can be tightened or the brake hub 3 can be loosened.

In step S1, the step of obtaining the moving distance of the second end of the lower brake pad pushed by the adjusting device includes:

S11. Obtain the moving distance of the fourth end of the long end 41;

S12. Calculate the moving distance of the third end of the short end 42 according to the obtained moving distance of the fourth end of the long end 41. The moving distance of the third end of the short end 42 is the moving distance of the second end of the lower brake pad pushed by the adjusting device.

In the above step S11, because the moving distance of the second end of the brake pad is difficult to obtain and the measurement is cumbersome, according to the structure of the L-shaped linkage 4, the fourth end of the long end 41 is used to brake the anchor device from the braking system to the second end of the brake pad. The moving distance after the brake system releases the anchor equipment is obtained indirectly.

Further, the drive assembly includes a screw and a handwheel, the handwheel is connected to the top of the screw, the screw is threaded with a first bushing and a second bushing, the first bushing is rotationally connected to the fourth end of the long end 41, The second bushing is located below the first bushing, and is rotatably connected with the brake support frame; rotating the handwheel, through the cooperation of the screw with the first bushing, drives the fourth end of the long end 41 to move up and down, thereby driving the short end 42 The third end pulls or pushes the second end of the lower brake pad, so that the brake band 1 is tightly held or the brake hub 3 is loosened.

In step S11, the step of obtaining the moving distance of the fourth end of the long end 41 includes:

S111. Obtain the number of turns of the handwheel when the brake system is released to the state where the anchor device can break down, and calculate the moving distance of the fourth end of the long end 41 according to the formula X ₁ =n*L ₃ , wherein n is the rotation of the handwheel The number of circles, L ₃ is the height of each circle of thread on the screw.

In the above step S111, it is only necessary to measure the height of each thread on the screw rod, so that when the crew breaks down, in the state where the brake system brakes the anchor equipment, turn the handwheel until the brake system is loosened to the state where the anchor equipment can break down , record the number of turns of the handwheel, and then calculate the moving distance of the fourth end of the long end 41 through the formula X ₁ =n*L ₃ according to the number of turns of the handwheel and the height of each thread, so as to obtain and calculate the length The moving distance of the fourth end of the long end 41, and the calculated moving distance of the fourth end of the long end 41 is more accurate. As in one embodiment, from the state of the braking system to tighten the anchor equipment to the state where the braking system is released to the anchor equipment can be anchored, the handwheel rotates 5 times in total, and the height of each circle of thread on the screw rod is 1 cm, by X ₁ =5*1=5 Calculated to obtain that the moving distance X ₁ of the fourth end of the long end 41 is 5 cm.

In the above step S12, according to the structure of the L-shaped linkage 4, when the fourth end of the long end 41 moves, the connection between the short end 42 and the long end 41 rotates around the third shaft, so the second end of the long end 41 can pass The moving distance of the four ends is used to calculate the moving distance of the third end of the short end 42. Since the third end of the short end 42 is connected with the second end of the lower brake pad, the moving distance of the third end of the short end 42 is the lower brake pad. The moving distance of the second end of , that is, the moving distance of the second end of the lower brake pad after the brake system tightens the anchor device to the brake system loosens the anchor device.

Further, in step S12, the step of calculating the moving distance of the third end of the short end 42 according to the obtained moving distance of the fourth end of the long end 41 includes:

S121. Calculate the movement distance of the third end of the short end 42 according to the following formula:

X ₂ =X ₁ *L ₂ /L ₁ , where X ₂ is the moving distance of the third end of the short end 42, X ₁ is the moving distance of the fourth end of the long end 41, L ₂ is the length of the short end 42, L ₁ is the length of the long end 41 .

In the above step S121, first measure the length X ₁ of the long end 41 and the length L ₂ of the short end 42, the length of the long end 41 is the distance from the position of the third rotating shaft on the long end 41 to the position of the first shaft sleeve, short The length of the end 42 is the distance from the position of the third rotating shaft on the short end 42 to its connecting point with the lower brake pad. Since both the long end 41 and the short end 42 rotate around the third rotating shaft, the third rotating shaft is taken as point O. When the brake system brakes the anchor equipment, the position of the fourth end of the long end 41 is marked as point A, and the position of the third end of the short end 42 is marked as point C. When the brake system releases the anchor equipment so that the anchor equipment can break down , the position of the fourth end of the long end 41 is marked as point B, and the position of the third end of the short end 42 is marked as point D. Therefore, when the anchor device is tightened by the brake system to the anchor device is released by the brake system, the fourth end of the long end 41 moves from point A to point B, and the third end of the short end 42 moves from point C to point D, that is, The distance of AB is X ₁ , and the distance of CD is X ₂ , as shown in FIG. 2 . Since both OA and OB are the length of the long end 41, △OAB is an isosceles triangle, and both OC and OD are the length of the short end 42, so △OCD is also an isosceles triangle, and both the long end 41 and the short end 42 are Rotate around the third rotation axis O, so the angle of ∠AOB is equal to the angle of ∠COD, so △OAB and △OCD are similar triangles. According to the similar triangle theorem, X ₂ /L ₂ =X ₁ /L ₁ can be obtained, and then X ₂ =X ₁ *L ₂ /L ₁ can be obtained, so that through the fourth end of the long end 41, from the brake system to the brake anchor device to the brake The moving distance after the system loosens the anchor device is calculated to obtain the moving distance from the third end of the short end 42 after the brake system brakes the anchor device to the brake system loosens the anchor device. For example, in one embodiment, it is measured that L ₁ is 90 cm, L ₂ is 13 cm, and X ₁ is 5 cm obtained from the above calculation, then the movement of the third end of the short end 42 can be obtained by calculating X ₂ =5*13/90=0.72 The distance _X2 is 0.72cm.

In the above step S2, the moving distance of the second end of the lower brake pad is the change in the arc length of the brake band 1 after braking to the brake hub 3 and after the brake hub 3 is released, so the arc length of the brake band 1 The amount of change can calculate the amount of change in the circumference of the circle where the brake band 1 is located.

Further, in step S2, the step of calculating the change in the circumference of the circle where the brake band 1 is located according to the obtained moving distance of the second end of the lower brake pad pushed by the adjusting device includes:

S21. Calculate the change in circumference of the circle where the brake band 1 is located according to the following formula:

C'=X ₂ *360/C, where C' is the change in circumference of the circle where the brake band 1 is located, C is the arc formed by the brake band 1, and X ₂ is the distance of the second end of the lower brake pad pushed by the adjustment device Moving distance.

In the above step S21, the combined arc of the upper brake band 1 and the lower brake band 1 is generally less than 360 degrees. For example, in an implementation, the combined arc of the upper brake band 1 and the lower brake band 1 is 300 degrees. C'=0.72*360/300=0.86 Calculate the circumference change C' of the circle where the brake band 1 is located to be 0.86cm.

In the above step S3, the step of calculating the gap between the brake limiting device 2 and the lower brake pad according to the change in the circumference of the circle where the brake band 1 is located includes

S31. Calculate the gap between the brake limiting device 2 and the lower brake pad according to the following formula:

S=C'/(2π), where S is the gap between the brake limiter 2 and the lower brake pad, and C' is the change in circumference of the circle where the brake band 1 is located.

In the above step S31, the formula S=C'/2π is obtained according to the formula of the circumference of the circle and the radius of the circle, and based on the change in the circumference of the circle where the brake band 1 is located, the circle where the brake band 1 is located is calculated according to the formula S=C'/2π The amount of change in the circumference of the circle is obtained to obtain the amount of change in the circumference radius. For example, in one embodiment, the variation C' of the circumference of the circle where the brake band 1 is located is 0.86 cm calculated in step S21. According to S=0.86/6.28=0.14, the circumference variation of the circle where the brake band 1 is located is 0.14 cm. , that is to say, the gap between the brake limiting device 2 and the lower brake pad is 0.14. The change in the radius of the circumference is the average value when the brake system is in good working condition and all parts of the brake belt 1 are evenly expanded. Lift the outward expansion force of the lower brake pad upwards to the upper brake pad, so that the upper brake pad also expands and breaks away from the brake hub 3, so that the upper brake pad and the lower brake pad of the brake band 1 can be expanded outward as much as possible, and the upper brake pad Plate and lower brake pad are even to the pressure of brake hub 3 points, and the wearing and tearing of upper brake pad and lower brake pad are also just quite, can prolong the service life of brake band 1 to the greatest extent like this, reduce the failure rate of the braking system of anchor equipment.
