Description

Technical Field

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

[0002] An electric winch is a mechanical device for anchoring and dropping anchors, and also serves as a mooring winch. It is an essential item for ships. Generally, it is a light and small lifting device that winds steel ropes or chains around a drum to lift or tow heavy objects.

[0003] After retrieval, it is found that a typical electric winch in the prior art is such as the one with the publication number CN215974718U, a marine energy-saving electric winch, which includes a housing. Inside the housing, there is a drum, and bearings are arranged at both ends of the drum. Due to the pulling force generated when the cable is released, the L-shaped mounting plate moves on the slide rod through the chute, reducing the harm of excessive friction between the cables caused by uneven arrangement on the drum during the release process. When retracting, the motor drives the drum to rotate to wind the cable. During this process, the hydraulic telescopic rod cooperates to control the L-shaped mounting plate with the push plate, making it move slowly and avoiding the difficulty of controlling the arrangement of the cable on the drum. Between the first fixed pulley and the second fixed pulley on the L-shaped mounting plate, there is a protective oil box with a slot opened at the top. By regularly adding protective oil to the protective oil box, the cable can be evenly coated on its surface when passing through, solving the problem that it is troublesome to apply the protective oil at regular intervals manually.

[0004] To sum up, when the existing marine electric winch is in use, although protective oil is applied to the outside of the cable, due to the high humidity during sea voyages, and during the voyage, the cable wound inside will get seawater. If the seawater is not removed in time, it will cause rust and corrosion inside, and even if protective oil is applied, it cannot extend its service life. To solve the above problems, improvements need to be made to the existing equipment. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are: This marine electric winch and installation method

[0020] (1) In order to solve the problem that when the existing marine electric winch is in use, although protective oil is applied to the outside of the cable, due to the relatively high humidity during sea voyages, if seawater is not removed in time, it will cause internal rust and corrosion, and even if protective oil is applied, it cannot extend its service life.

Then, it passes through the lower pressing roller, so that the cable body comes into contact with the protective oil in the inner cavity of the guide seat, thereby applying protective oil to the cable body and improving the service life of the cable body;

[0021] (2) In order to solve the problem that when the existing marine electric winch is in use, it is generally fixedly installed, resulting in the inability to move the installation position according to the actual situation or adjust the use direction, reducing its practicality in use. In this application, the first electric linear guide rail is set to drive the winch frame to move, facilitating the horizontal movement of the position where the winch frame is placed. Then, the rotating motor drives the transmission pulley, connecting belt and support rotating shaft to rotate, facilitating the overall rotation of the protective chassis, thereby facilitating the adjustment of the placement azimuth angle and improving the practicality in use.

[0033] Please refer to Figures 1-9 , the present invention provides a technical solution: a marine electric winch, according to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, a winding drum 2 is arranged inside the winch frame 1, and one end of the winding drum 2 penetrates through one side of the winch frame 1 and is connected to the output end of the driving motor 3. At the same time, a cable body 4 is wound around the outer side of the winding drum 2. Positioning bearings 101 are symmetrically arranged on one side of the winch frame 1, and a lead screw 6 is arranged between the two positioning bearings 101. At the same time, one end of the lead screw 6 is connected to the other end of the winding drum 2 through a connecting drive assembly 7. The connecting drive assembly 7 includes an extension shaft 701 and a support frame 702. One end of the extension shaft 701 penetrates through the winch frame 1 and is connected to the winding drum 2. At the same time, the other end of the extension shaft 701 is slidably connected to one side of the protective bottom frame 501 through the support frame 702. A moving guide cylinder 703 is sleeved on the outer side of the extension shaft 701.

At the same time, a first drive gear 704 and a second drive gear 705 are respectively arranged at both ends of the outer side of the moving guide cylinder 703. A connecting bearing is arranged on the inner side of the middle of the moving guide cylinder 703, and a vertical plate 706 is arranged on the outer side of the connecting bearing. At the same time, one side of the vertical plate 706 is connected to one side of the upper end of the protective cover plate 103 through an electric telescopic rod 707. A first transmission gear 709 and a second transmission gear 710 are arranged at the rear sides of the first drive gear 704 and the second drive gear 705. The first transmission gear 709 and the second transmission gear 710 are arranged on the outer side of one end of the lead screw 6. At the same time, the first drive gear 704 is connected to the first transmission gear 709 through a connecting gear 708. The connecting gear 708 is arranged at the upper end of the support frame 702.

[0034] During use, when the driving motor 3 drives the winding drum 2 to rotate to wind the cable body 4, the extension shaft 701 rotates synchronously. Then, the extension shaft 701 drives the moving guide cylinder 703, the first drive gear 704, and the second drive gear 705 to rotate, so that the second transmission gear 710 and the lead screw 6 meshed with the second drive gear 705 rotate. Then, under the drive of the lead screw 6, the whole guiding and oiling assembly 8 moves horizontally, so that the cable body 4 is evenly wound on the outer side of the winding drum 2. When the guiding and oiling assembly 8 needs to move in the reverse direction on the lead screw 6, the electric telescopic rod 707 is started to push the vertical plate 706 to move, so that the moving guide cylinder 703 moves horizontally on the extension shaft 701 under the drive of the vertical plate 706 until the first drive gear 704 meshes with the connecting gear 708. Then, under the drive of the connecting gear 708 to drive the first transmission gear 709 to rotate, the lead screw 6 rotates in the reverse direction, so that the guiding and oiling assembly 8 moves horizontally in the reverse direction.

[0035] According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, a guide and oiling assembly 8 is provided on the lead screw 6, and the guide and oiling assembly 8 includes a guide seat 801. The lower end of the guide seat 801 near one side of the winch frame 1 is slidably connected to the moving chute 102 opened at the inner bottom end of the winch frame 1 through a slider.

The drying and dehumidifying assembly 9 includes a drying box 901, and the drying box 901 is of a convex structure. The upper and lower ends of the middle of the drying box 901 are connected to the protective bottom frame 501 through correspondingly arranged second electric linear guides 902. The drying box 901 is driven by the second electric linear guides 902 to move, which is convenient for the drying box 901 to move horizontally synchronously with the guide seat 801, improving the practicality of use. The outer end of the drying box 901 penetrates through the protective bottom frame 501 and is located in the guide through hole 5011 opened at the rear side of the winch frame 1. At the same time, water-absorbing outer covers 903 are symmetrically arranged on the outer side of the inside of the drying box 901. A plurality of electric heating tubes 904 are equidistantly and symmetrically arranged on one side of the inside of the drying box 901 close to the guide seat 801.

[0036] During use, the electric heating tubes 904 are started to increase the temperature inside the drying box 901. Then, under the action of the water-absorbing outer covers 903, the seawater adhered to the outer side of the cable body 4 is first removed. Then, the heat inside the drying box 901 is conducted to the cable body 4, so that the seawater inside the cable body 4 evaporates and is dried. After completion, under the action of the pressing roller 802, the dried cable body 4 comes into contact with the protective oil, so that the protective oil covers the outer side of the cable body 4. Then, the excess protective oil is adsorbed by the conveying roller 803 while the cable body 4 is guided and conveyed.

The middle of the bottom of the lower end of the protective chassis 501 is connected to the middle of the upper end of the installation base 506 through a support rotating shaft 505. The installation base 506 is of a circular structure. A rotating motor 507 is arranged inside the upper end of the installation base 506 on one side of the support rotating shaft 505. Transmission belt pulleys 508 are arranged on both the rotating motor 507 and the support rotating shaft 505. The two transmission belt pulleys 508 are connected by a connecting belt 509. Support columns 510 are symmetrically arranged on the outer side of the lower end of the protective chassis 501. The bottom of the support columns 510 is connected to an annular guide 511 arranged inside the outer side of the upper end of the installation base 506 through a universal joint.

[0038] During use, the winch frame 1 is driven to move by the first electric linear guide 502, which is convenient for horizontally moving the position where the winch frame 1 is placed. The rotating motor 507 drives the transmission belt pulley 508, the connecting belt 509 and the support rotating shaft 505 to rotate, so that the protective chassis 501 rotates. At the same time, the support columns 510 arranged at the lower end of the protective chassis 501 move on the annular guide 511, thereby improving the stability when adjusting the angular orientation of the winch frame 1. After the adjustment is completed, the electric hydraulic cylinder 503 is started to push the electromagnetic seat 504 to fit with the hull, and then the electromagnetic seat 504 is powered on to further improve the stability of the electric winch during use.

At the same time, the support columns 510 arranged on the side of the lower end of the protective chassis 501 are connected to the annular guide 511 through universal joints. Then, the winch frame 1 is placed on the upper end of the protective chassis 501, so that both sides of the lower end of the winch frame 1 are connected to the corresponding first electric linear guides 502. Then, the electric hydraulic cylinder 503 is started to push the electromagnetic seat 504 to fit with the hull;

[0041] (2) Next, 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 attached to the upper end of the conveying roller 803 arranged on one side inside the guide seat 801, and the upper end of the cable body 4 is attached to the bottom of the pressing roller 802. Then, start the infusion pump 11 to convey the protective oil inside the oil storage tank 12 to the cavity below the pressing roller 802 inside the guide seat 801 through the oil delivery pipe 10, so that the cable body 4 contacts the protective oil. Then, the cable body 4 passes through the other side of the guide seat 801 and enters the inside of the drying box 901. After the cable body 4 is located between the two water-absorbing outer covers 903, finally, it passes through the other side of the guide seat 801 and extends to the outside of the protective chassis 501 to be connected to other objects;
