Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a marine pneumatic winch. Background Technique

[0002] Winches are divided into three categories according to power: pneumatic, manual, electric, and hydraulic. Classified by use, they can be divided into construction winches and marine winches. According to functions, winches can be divided into: marine winches, engineering winches, mining winches, cable winches, etc. According to the drum form, they are divided into single-drum and double-drum. Among them, the pneumatic winch uses a vane-type pneumatic motor as the power, and transmits the power to the drum through a planetary gear reducer to lift heavy objects.

[0003] After retrieval, it is found that a typical pneumatic winch in the prior art is, for example, the one with the publication number CN215756092U, a marine pneumatic winch, which includes a housing.

There is no need to use handling tools such as cranes, saving manpower and material resources. The housing protects the pneumatic winch, reduces the corrosion speed of the internal soft ladder, and increases its service life.

[0004] To sum up, when the existing pneumatic winch is in use, the distribution of the winch rope during winding is not uniform enough, resulting in poor stability and affecting the normal operation of the pneumatic winch. In view of the above problems, it is necessary to improve the existing equipment. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a marine pneumatic winch. According to Figure 1 and Figure 4 shown, on both sides of the bottom of the lower end of the protective housing 1, support chassis 2 are symmetrically arranged, and in the middle of the protective housing 1, a winding and unwinding assembly is arranged. At the same time, a mooring line 8 is wound around the outside of the winding and unwinding assembly. The winding and unwinding assembly includes a rotating shaft 3, a winch drum 4, a baffle 5, a speed governor 6 and a driving motor 7. The winch drum 4 is snap-connected to the outside of the rotating shaft 3. The winch drum 4 is an adjustable structure. The winch drum 4 is a prior art. Through the adjustment of the winch drum 4, the tightness of the winding of the mooring line 8 can be adjusted, so that the mooring line 8 fits better with the winch drum 4. At the same time, baffles 5 are symmetrically opened and closed on both sides of the winch drum 4. At the same time, one end of the rotating shaft 3 is connected to the output end of the driving motor 7 through the speed governor 6.

[0022] During use, start the driving motor 7 to drive the speed regulator 6 and the rotating shaft 3 to rotate, so that the cable 8 enters the protective housing 1 through the guide sleeve 9, and the cable 8 is wound outside the cable reel 4 between the two baffles 5.

[0023] According to Figure 1 、 Figure 2 and Figure 4 As shown, a through groove is formed in the middle of one side of the protective housing 1, and a guiding component is arranged inside the through groove. The guiding component includes a guide sleeve 9, and the guide sleeve 9 is snap-fitted with the engaging hole formed between the positioning seat 10. The upper end and the lower end of the positioning seat 10 are respectively connected to the corresponding ball nut seats 11. At the same time, the two ball nut seats 11 are respectively connected to the corresponding ball screws 12. One end of the two ball screws 12 penetrates through the protective housing 1 and is connected to the corresponding reciprocating motor 13. The guide sleeve 9 and the protective housing 1 form a moving structure through the positioning seat 10, the ball nut seats 11, the ball screws 12 and the reciprocating motor 13.

[0024] During use, start the reciprocating motor 13 to drive the ball screw 12 to rotate, so that the ball nut seat 11 arranged on the ball screw 12 drives the positioning seat 10 and the guide sleeve 9 to move horizontally as a whole, so that the cable 8 can be evenly arranged on the cable reel 4 when being recycled, which is convenient for the pneumatic winch to wind and unwind the cable 8 on the cable reel 4 more stably.

[0025] According to Figure 1 、 Figure 3 and Figure 4As shown in the figure, a leveling assembly is installed on the other side of the protective housing 1. The leveling assembly includes a positioning frame 16, a telescopic rod 17, a buffer spring 18, and a leveling pressing plate 19. There are two positioning frames 16, and the two positioning frames 16 are respectively arranged outside the through holes opened on one side of the protective housing 1. At the same time, a telescopic rod 17 is arranged outside the middle of the two positioning frames 16. The telescopic rod 17 is of a T-shaped structure, and one end of the telescopic rod 17 passes through the positioning frame 16 and the buffer spring 18 and is connected to one side of the leveling pressing plate 19. At the same time, the other side of the leveling pressing plate 19 is attached to the outer side of the winding rope 8 wound on the winding drum 4. When the winding rope 8 is wound, the outer diameter of the winding drum 4 expands as the winding amount of the winding rope 8 increases, so that the leveling pressing plate 19 squeezes the telescopic rod 17 and the buffer spring 18 under the influence of the winding rope 8. Affected by the spring force of the buffer spring 18, the leveling pressing plate 19 is always attached to the outer side of the winding rope 8, making the winding of the winding rope 8 more flat. On the side of the leveling pressing plate 19 close to the telescopic rod 17, limiting rods 20 are symmetrically arranged, and the limiting rods 20 pass through the protective housing 1 and extend to the outside of the protective housing 1. At the same time, the limiting rods 20 are slidably connected to the protective housing 1. By moving the limiting rods 20 in the protective housing 1 under the push of the leveling pressing plate 19, the stability of the leveling pressing plate 19 during use is improved, and it is not easy to shift. One side of the upper end of the protective housing 1 is connected to a protective cover plate 14 through a positioning column 15. At the same time, the protective cover plate 14 is located above the winding and unwinding assembly. Through the protective cover plate 14, it is convenient to protect the winding and unwinding assembly and improve the protection of the winding and unwinding assembly and the storage of the winding rope 8.

[0026] The orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only a simplified description for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the protection scope of the present invention.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
