Description

Technical Field

[0001] The present invention relates to the technical field related to electric winches, and in particular to a marine electric winch and an installation method thereof. Background Art

[0002] Electric winch is a mechanical device for lifting and dropping anchor. It is also used for winding cables. It is a necessary item for ships. It is a light and small lifting equipment that generally uses a drum to wind a wire rope or chain to lift or pull heavy objects.

[0003] After searching, it is found that the typical electric winch in the prior art is disclosed in CN215974718U, which is an energy-saving electric winch for ships. It includes a shell, a drum is arranged inside the shell, and bearings are arranged at both ends of the drum. The tension generated when the cable is released makes the L-shaped mounting plate move on the slide rod through the slide groove, reducing the damage caused by excessive friction between the cables due to uneven arrangement of the cables on the drum during the release process. When retracting, the motor drives the drum to rotate and reel the cable. During the process, the hydraulic telescopic rod cooperates, so that the push plate controls the L-shaped mounting plate to move slowly, avoiding the difficulty in controlling the arrangement of the cables on the drum; a protective oil box is arranged between the first fixed pulley and the second fixed pulley on the L-shaped mounting plate, and a slot is opened on the top of the protective oil box. Protective oil is added to the protective oil box regularly, so that the cable can be evenly applied on its surface when it passes, solving the problem of manual brushing of protective oil at intervals.

[0004] In summary, when the existing marine electric winch is in use, although protective oil is applied to the outside of the cable, the humidity is high during sea navigation, and during navigation, the cable wound inside will be exposed to sea water. If the sea water is not removed in time, it will cause rust and corrosion inside. Even if protective oil is applied, its service life cannot be extended.

The middle upper end and the lower end of the drying box (901) are connected to the protective base frame (501) through correspondingly arranged second electric linear guide rails (902), and the outer end of the drying box (901) passes through a guide through hole (5011) provided on the rear side of the winch frame (1) of the protective base frame (501). At the same time, a water-absorbing outer cover (903) is symmetrically arranged inside and outside the drying box (901), and a plurality of electric heating tubes (904) are symmetrically arranged at equal distances on one side of the drying box (901) near the guide seat (801).

9. A method for installing a marine electric winch, characterized in that: The following steps are involved: (1) First, the mounting base (506) is fixed on the hull by fixing bolts, and then the lower end of the protective frame (501) is connected to the top of the support shaft (505) arranged in the middle of the upper end of the mounting base (506), and at the same time, the support column (510) arranged on the side of the lower end of the protective frame (501) is connected to the annular guide rail (511) through a universal joint, and then the winch frame (1) is placed on the upper end of the protective frame (501), so that the two sides of the lower end of the winch frame (1) are connected to the corresponding first electric linear guide rails (502), and then the electric hydraulic cylinder (503) is started to push the electromagnetic seat (504) to fit with the hull; (2) Then, one end of the cable body (4) wound around the outer side of the winding drum (2) arranged inside the winch frame (1) is passed through one side of the guide seat (801), so that the lower end of the cable body (4) is in contact with the upper end of the conveying roller (803) arranged inside one side of the guide seat (801), and the upper end of the cable body (4) is in contact with the bottom of the lower pressure roller (802), and the infusion pump (11) is started to convey the protective oil inside the oil storage tank (12) to the cavity below the lower pressure roller (802) inside the guide seat (801) through the oil delivery pipe (10), so that the cable body (4) is in contact with the protective oil, and then the cable body (4) passes through the other side of the guide seat (801) and enters the drying box (901), so that the cable body (4) is located in the two water-absorbing outer covers (903), and finally passes through the other side of the guide seat (801) and extends to the outside of the protective bottom frame (501) to connect with other objects; (3) Then, the first transmission gear (709) and the second transmission gear (710) are installed on one side of the screw rod (6) so that the first transmission gear (709) is meshed and connected with the connecting gear (708) provided on the support frame (702), and then one end of the extension shaft (701) is connected to the winding drum (2), and the movable guide cylinder (703) is sleeved on the outside of the extension shaft (701) so that the first drive gear (704) is located on the upper side of the connecting gear (708), and the second drive gear (705) is meshed with the second transmission gear (710), and then the other end of the extension shaft (701) is connected to the support frame (702), and then the vertical plate (706) is connected to the upper end of the protective cover plate (103) through the electric telescopic rod (707).
