Description

Technical Field

[0001] This utility model belongs to the field of marine machinery technology, specifically relating to a single-person operated integrated anchor winch machine for ships. Background Technology

[0002] Ship's anchor winches and mooring winches are intermittently operating devices. During operation, they drive the raising and lowering of the anchor and mooring lines, respectively. They require torque from a power source such as an electric motor, and the work is completed through the rotation of the anchor chain wheel and the rope reel. After operation, to protect the electric motors of the anchor winches and mooring winches, the torque transmission between their working ends and the power source must be disconnected.

[0003] The mechanism that connects and disconnects the torque transmission between the working end and the power source is the clutch. When engaged, the working end rotates; when disengaged, it does not rotate. If the working end rotates unexpectedly for other reasons, such as the anchor chain moving due to its own weight, and the anchor chain dragging the anchor chain wheel, the unexpected rotation can easily be transmitted to the motor due to the structure of the reduction gearbox, which can rotate in both directions. The anchor chain wheel rotates at a low speed but with a large torque. According to the law of conservation of energy, the same torque will result in high-speed rotation and low torque on the motor, causing severe friction and damage to the motor brake friction pads. Similarly, mooring winches may experience unexpected rotation of the rope reel due to tides or water currents, leading to the same situation as anchor winches and wear on the motor brake friction pads.

[0004] Therefore, the clutch must be engaged when operating anchor winches and mooring winches; the clutch must be disengaged immediately after the operation is completed.

[0005] To engage or disengage the clutch, the master controller must be operated to rotate the sprocket or rope reel to the appropriate position. Since the master controller and the clutch are at least 1.5 meters apart, one person cannot operate both mechanisms at the same time. Only two people can work together: one person operates the master controller to slowly rotate the sprocket or rope reel, and the other person operates the clutch to engage or disengage.

[0006] Since most ships are relatively large, typically ranging from 100 to 390 meters in length and 25 to 60 meters in width, anchor winches and mooring winches are usually located at the bow and stern respectively. They are generally operated by two people per group, but due to the large area they cover, two groups of four people are needed to complete the task.

[0007] Figure 1 The image shows the arrangement of the anchor winch and mooring winch on the ship, which is 210 meters long and 27.2 meters wide, making it a small to medium-sized vessel.

[0008] Figure 2 and Figure 3The image shows the arrangement of the anchor chain wheel and rope winding wheel clutches of the anchor winch integrated machine, as well as the installation position of the master controller. It can be seen that because the master controller is far away from each clutch, one person cannot operate two mechanisms at the same time.

[0009] In conclusion, there is a need to research a ship anchor winch integrated machine that can be operated by a single person. Utility Model Content

[0010] The purpose of this invention is to provide a single-person operated ship anchor winch integrated machine to solve the above-mentioned problems.

[0011] The objective of this utility model is achieved through the following technical solution:

[0012] One of the technical solutions of this utility model is to provide a single-person operated ship anchor winch integrated machine, which includes the following structure:

[0013] An anchor winch, the anchor winch including an anchor chain wheel, the anchor chain wheel being connected to an electric motor, the electric motor being connected to a master controller, receiving signals from the master controller to rotate the anchor chain wheel for raising, lowering and driving the anchor chain;

[0014] A mooring winch, comprising a rope reel connected to an electric motor, the electric motor being connected to a master controller and receiving signals from the master controller to rotate the rope reel for raising, lowering and driving the cable.

[0015] Clutches, including chain wheel clutches and rope reel clutches;

[0016] The clutch control lever includes an anchor chain wheel clutch control lever and a rope reel clutch control lever; the anchor chain wheel clutch control lever is used to control the engagement or disengagement of the anchor chain wheel clutch, and the rope reel clutch control lever is used to control the engagement or disengagement of the rope reel clutch.

[0017] The control switches include an anchor chain wheel control switch and a rope reel control switch; the anchor chain wheel control switch and the rope reel control switch are respectively connected to the master controller via control lines; the anchor chain wheel control switch is used to control the forward or reverse rotation of the anchor chain wheel, and the rope reel control switch is used to control the forward or reverse rotation of the rope reel.

[0018] The bearing support seats, the number of which corresponds to the number of clutches, are used to support the main shaft of the ship's anchor winch.

[0019] Furthermore, each rope reel is equipped with a clutch and a bearing support, and each anchor chain reel is equipped with a clutch and a bearing support.

[0020] Furthermore, the master controller includes an action control switch, which is connected to the control circuit and then to the anchor chain wheel control switch or the rope reel control switch. The action control switch includes an anchor chain wheel action control switch and a rope reel action control switch; the anchor chain wheel action control switch is connected to the anchor chain wheel control switch, and the rope reel action control switch is connected to the rope reel control switch.

[0021] Furthermore, the control switch is installed at a distance less than one arm span from the clutch lever, which is 0.2 to 1 meter, allowing for single-person operation. In this case, one hand can hold the jog button to maintain slow rotation, while the other hand holds the clutch lever. When the clutch enters the engagement zone, the clutch lever is moved to engage the clutch; disengagement is the reverse. The anchor chain wheel control switch is installed on the bearing support of the anchor chain wheel, and the rope reel control switch is installed on the bearing support of the rope reel. Each control switch that needs to be operated simultaneously with the clutch lever is located on the bearing support closest to the clutch lever.

[0022] Furthermore, the control switch is set as a jog button. Pressing and holding the jog button will cause the anchor chain wheel or rope reel to rotate in the forward direction, and releasing it will stop it. Pressing and holding the jog button again will cause the anchor chain wheel or rope reel to rotate in the reverse direction, and releasing it will stop it.

[0023] Furthermore, this invention connects the control circuit via a jog button, and a dedicated speed control program is written. Pressing the button activates the circuit and executes the program, causing the corresponding anchor chain wheel or rope reel to rotate forward or backward at a constant speed. Releasing the jog button disconnects the control circuit, the speed control program is not executed, and the anchor chain wheel or rope reel comes to a stop.

[0024] Furthermore, the linear speed of the anchor chain wheel or rope reel is 9-15 meters per minute.

[0025] Furthermore, the motor is connected to a frequency converter and a programmable logic controller (PLC) and is controlled by the frequency converter and the PLC. The frequency converter is used to control the speed of the motor rotation, and the PLC is used to control the forward or reverse rotation of the motor.

[0026] Furthermore, the motor is connected to a gearbox, which drives the anchor chain wheel and the rope winding wheel to rotate.

[0027] Furthermore, the working principle of the above-mentioned single-person operated ship anchor winch is provided as follows: After pressing the jog button, the control circuit is connected, the motor is powered on, and the frequency converter and programmable logic controller (PLC) are powered on at the same time. The PLC executes a special speed control program, and the motor rotates forward or in reverse at the set speed. The rotation output is sent to the reduction gearbox, and after a series of transmissions, it drives the main shaft to rotate. The anchor chain wheel or rope winch installed on the main shaft rotates synchronously. At this time, the operator checks the status of the clutch, which is either engaged or disengaged. After reaching the desired position, the button is released to complete the operation.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. The anchor winch and mooring winch can be operated at low speed in both directions with just one jog button, making operation very convenient.

[0030] 2. Operations that previously required two people to open and close the anchor winch and mooring winch can now be completed by one person.

[0031] 3. All clutches on the anchor winch and the hoist can be opened and closed by a single jog button. The wiring is simple and does not affect each other, resulting in low cost. Attached Figure Description
