Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] figure 1 It is a structural schematic diagram of the automatic ship mooring machine of the present invention.

[0021] See figure 1 The automatic ship mooring machine provided by the present invention comprises a motor 1, the non-shaft end of the motor 1 has a DC electromagnetic brake 2, the motor 1 is connected to the cable drum 4 through a reduction gear box 5, and the motor 1 and The time relay 3 is electrically connected and intermittently started under the control of the time relay. The cable pull force setting method of the automatic ship mooring machine provided by the invention uses a motor to detect the pull force of the cable. The specific steps are as follows: the electric motor starts and runs intermittently in the direction of cable take-up with a predetermined cycle, and the locked-rotor torque of the electric motor is the tensio...

Abstract

The invention relates to an automatic ship mooring machine and a mooring rope tension setting method. The automatic ship mooring machine comprises an electromotor, a mooring rope and a time relay, wherein the non drive end of the electromotor is provided with a direct current (DC) electromagnetic brake; the electromotor is connected with the mooring rope through a reduction gear box; and the electromotor is electrically connected with the time relay and is intermittently started under the control of the time relay. The automatic ship mooring machine and the mooring rope tension setting method realize automatic ship mooring through intermittent start operation by setting the stall torque of the electromotor as a tension detection setting value, improve safety and reliability of ships and reduce labor intensity of crews.

Description

technical field [0001] The invention relates to a mooring machine and a cable tension setting method thereof, in particular to an automatic ship mooring machine and a cable tension setting method thereof. Background technique [0002] When the ship is moored, the draft of the ship will change due to the change of the cargo capacity; the level between the deck surface and the wharf level will change due to the fluctuation of the tide; the tilt of the ship will be caused by loading and unloading of heavy cargo; The movement and sway of the ship caused by waves and currents, wind direction, etc., and many other reasons cause a sharp increase or decrease in the tension of the mooring cable, which will cause the ship to shift or the cable to break and cause danger. In order to avoid the occurrence of this type of accident, the crew must regularly check the mooring cables, and manually take in or release the cables based on experience. In this way, the pulling force of the cable...
