Wherein the adjusting part 53 is configured to controllably adjust the spacing between the first brake disk 51 and the second brake disk 52.

The anchor windlass provided by the embodiment of the disclosure is provided with a brake assembly 5, the brake assembly 5 comprises a rotary disc 50, a first brake disc 51, a second brake disc 52 and an adjusting part 53, wherein the rotary disc 50 is fixedly sleeved outside an input shaft 21 of a speed reducing assembly 2, the rotary disc 50 can rotate along with the input shaft 21, the first brake disc 51 and the second brake disc 52 are further respectively arranged on two sides of the rotary disc 50, the first brake disc 51 is positioned on the frame 1, the second brake disc 52 is connected with the first brake disc 51 through the adjusting part 53, and the adjusting part 53 can adjust the distance between the two brake discs, so that the two brake discs can clamp the rotary disc 50 through the adjusting part 53 to brake the rotary disc 50, thereby braking the input shaft 21. When the anchor windlass is in anchoring operation, the two brake discs are adjusted to be at a proper distance through the adjusting part 53 so as to clamp the turntable 50. When the anchor is broken, the output shaft 22 of the speed reducing component 2 is reversely dragged by the anchor chain wheel 3 to passively rotate at a high speed, the generated power is transmitted to the input shaft 21 through the speed reducing component 2 to drive the input shaft 21 to rotate, the input shaft 21 is braked by the turntable 50 and the two brake discs in the rotating process so as to consume the kinetic energy generated in the anchor releasing process, so that the anchor chain wheel 3 can be released at a stable speed to avoid the phenomenon of galloping. When the operation of breaking down, only need adjust to suitable interval with two brake discs, braking component 5 just can be automatic to 3 brakeings of anchor chain wheel, and the in-process need not the rotation condition that technical staff paid attention to anchor chain wheel 3 constantly, reduces the operation degree of difficulty of breaking down.

Alternatively, as shown in fig. 2, the adjusting section 53 includes: a connecting rod 531, an elastic reset piece 532 and a locking piece 533; one end and the first brake disc 51 fixed connection of connecting rod 531, the equal movable suit of elasticity piece 532 and second brake disc 52 that resets on connecting rod 531, elasticity piece 532 that resets is located between first brake disc 51 and the second brake disc 52, and both ends link to each other with first brake disc 51 and second brake disc 52 respectively.

In use, if the distance between the first brake disc 51 and the second brake disc 52 is to be reduced, the locking member 533 can be controlled to move on the connecting rod 531 towards the first brake disc 51 to press the second brake disc 52 towards the first brake disc 51, so that the two brake discs clamp the rotating disc 50 more tightly, thereby increasing the braking force on the rotating disc 50, and the elastic restoring member 532 is pressed to accumulate the elastic force in the process.

When the brake disc clamping device is used, if the distance between the first brake disc 51 and the second brake disc 52 is to be increased, the locking member 533 can be controlled to move on the connecting rod 531 in the direction away from the first brake disc 51, at this time, the elastic resetting member 532 is released, the elastic force accumulated by the elastic resetting member 532 pushes the second brake disc 52 to gradually move away from the first brake disc 51, and the clamping force of the two brake discs on the rotating disc 50 is weakened, so that the braking force on the rotating disc 50 is reduced.

In the above implementation manner, after the locking member 533 is moved to a suitable position, the locking member 533 is controlled to be locked on the connecting rod 531, so as to prevent relative displacement between the two brake discs, so as to ensure that the braking force applied to the turntable 50 by the two brake discs cannot be changed easily, so as to control the anchor chain wheel 3 to anchor at a stable speed, and avoid the occurrence of a runaway phenomenon.

Illustratively, as shown in fig. 2, the resilient return 532 may be a spring. The spring is fitted around the connecting rod 531 such that one end of the spring abuts against the first brake disk 51 and the other end of the spring abuts against the second brake disk 52. When the first brake disk 51 is pressed to approach the second brake disk 52, the spring is compressed to accumulate an elastic force; when the external force applied to the first brake disk 51 disappears, the spring releases the elastic force to push the second brake disk 52 away from the second brake disk 52, so that the second brake disk 52 is reset.

As shown in fig. 3, the brake assembly further includes: the locking device comprises an adjusting cylinder 54 and a motor 55, wherein one end of the adjusting cylinder 54 is closed, the other end of the adjusting cylinder is opened, the closed end of the adjusting cylinder 54 is coaxially connected with a rotating shaft of the motor 55, the open end of the adjusting cylinder 54 is movably sleeved outside the locking sleeve along the axial direction of the locking sleeve, and the adjusting cylinder 54 and the locking sleeve are circumferentially fixed.

The cross section of the locking sleeve can be rectangular or polygonal, so that after the adjusting cylinder 54 is sleeved outside the locking sleeve, the motor 55 drives the adjusting cylinder 54 to rotate, and then the locking sleeve can be driven to rotate, and therefore the purpose that the locking sleeve moves along the connecting rod 531 in the axial direction is controlled. The locking piece 533 can be automatically adjusted by controlling the motor 55, so that the locking sleeve is convenient to use.

Optionally, the brake assembly further includes a controller and a speed measuring unit, the speed measuring unit and the motor 55 are both electrically connected to the controller, and the speed measuring unit is configured to detect the rotation speed of the input shaft 21.

The Controller may be a Programmable Logic Controller (PLC), and the PLC is a Programmable memory, in which instructions for performing operations such as Logic operation, sequence control, timing, counting, and arithmetic operation are stored, and controls various devices through digital or analog input and output.

Wherein, the speed measurement piece can be a speed sensor, and the speed sensor is located input shaft 21, and the speed sensor is used for detecting the rotational speed of input shaft 21.

In the embodiment of the present disclosure, the speed measurement component and the motor 55 are both electrically connected to the controller, and the controller is configured to obtain the rotation speed detected by the speed measurement component, and control the motor 55 to rotate forward or backward in real time based on the rotation speed.

Thus, after acquiring the real-time rotation speed of the turntable 50, the controller can control the motor 55 to act according to the current rotation speed to adjust the braking force applied to the turntable 50 in real time, so as to control the anchor chain wheel 3 to release the anchor at a stable speed.

For example, if the anchor chain wheel 3 is controlled to stably release the anchor at a set speed, such as 5m/s, the controller may obtain the rotation speed detected by the speed measuring component every set time 1s to 3s, determine the rotation speed of the output shaft 22 of the speed reducing assembly 2 according to the rotation speed of the input shaft 21, and determine the rotation speed of the anchor chain wheel 3 according to the rotation speed of the input shaft 21.

After the rotating speed of the anchor chain wheel 3 is determined, the controller compares the calculated current rotating speed of the anchor chain wheel 3 with a set speed; if the current rotating speed of the anchor chain wheel 3 is lower than the set speed, the controller controls the motor 55 to rotate reversely to control the two brake discs to separate, and reduce the braking force applied to the rotating disc 50, so that the rotating speed of the input shaft 21 can be gradually increased until the current rotating speed of the anchor chain wheel 3 is increased to the set speed; if the current rotation speed of the anchor sprocket 3 is greater than the set speed, the controller controls the motor 55 to rotate forward to control the two brake discs to approach each other, and increases the braking force applied to the rotating disc 50, so that the rotation speed of the input shaft 21 can be gradually reduced until the current rotation speed of the anchor sprocket 3 is reduced to the set speed. Thereby realizing the purpose of controlling the anchor chain wheel 3 to anchor at a stable speed.
