Description

Technical Field

[0001] The present application relates to the technical field of lifters, and in particular to a lifter with planetary drive. Background Art

[0002] At present, the existing lifters are used for lifting and lowering heavy objects. To lift goods by rope, a lifter tool is needed. For example, in the prior patent application number: CN202321461845.1, the rope body can pass through the rope reel, and by driving the rope reel to rotate, the lifter can be lifted up and down on the rope body, and the heavy object can be fixed on the outer shell of the lifter, thereby realizing the lifting function of the goods.

[0003] As for the above-mentioned products, based on their structures, we can clearly know that they need to be driven by external motors or electric drills. We know that if the cargo weight is heavy, the rope reel needs a larger load capacity to achieve lifting. As for how to increase the load capacity of the rope reel, that is, how to increase the torque of the rope reel, at this time, we can easily think of increasing the torque of the drive motor and using a motor with greater torque output. However, if this kind of motor is used, it is undoubtedly necessary to configure a separate motor. This makes it impossible to use conventional electric drill tools, which is very inconvenient.

[0004] It can be seen from this that the technical problem that needs to be solved is how to improve the lifter while maintaining the original motor torque operation for power input drive so as to effectively improve the torque and safety performance. Utility Model Content

[0007] Optionally, an insertion shaft is provided on the inner side of the movable gear disc, and the insertion shaft is plugged and fixed on the rope winding wheel to drive the rope winding wheel.

[0008] Optionally, the outer diameter of the movable gear plate is smaller than the circumferential diameter of the inner wall of the protrusion, and the tooth shape of the movable gear plate and the tooth shape of the stationary gear ring are staggered and meshed with the planetary assembly.

[0024] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0026] The following is combined with Figure 1-4 The specific implementation methods of this application are further described. Example

[0027] The present application embodiment discloses a lifter with planetary drive, referring to Figure 1 and Figure 2As shown, it includes a housing 1, a rope reel 2, and a cover 3. The rope reel 2 is rotatably mounted on one side of the housing 1 and shielded by the cover 3. A bearing can be added to the rotatable mounting structure of the rope reel 2 and the housing 1. An installation chamber 11 is provided on the other side of the housing 1, and a planetary transmission mechanism 4 for driving the rope reel 2 is installed in the installation chamber 11. The planetary transmission mechanism 4 includes a movable gear plate 41, a stationary gear ring 42, a planetary assembly 43, a central gear 44, and an end cover 45. A plurality of protrusions 12 are provided on the peripheral wall of the installation chamber 11. The movable gear plate 41 is fixedly connected to the axial position of the rope reel 2. The outer periphery of the stationary gear ring 42 is fixedly engaged with the protrusions 12 and is located on the outer side of the movable gear plate 41. The planetary assembly 43 is assembled on the movable gear plate 41 and the stationary gear ring 42 and transmits the power. The central gear 44 is meshed with the center of the planetary assembly 43 and transmits the power. The end cover 45 is sleeved on the shaft of the central gear 44 and fixed with the housing 1 to shield the installation chamber 11.

[0028] The planetary transmission mechanism 4 is used for transmission, so that power is input from the central gear 44, driving the planetary assembly 43 to rotate, and then driving the movable gear plate 41 to rotate, thereby driving the rope wheel 2 to rotate. Through this structure, the load capacity is significantly increased. After the power of the same electric drill is input, the rope wheel 2 can rotate and drive heavier objects to perform lifting operations.

[0029] Based on the above structure, an insertion shaft 411 is provided on the inner side of the movable gear plate 41 , and the insertion shaft 411 is inserted and fixed on the rope winding wheel 2 to drive the rope winding wheel 2 .

[0030] In addition, the outer diameter of the movable gear plate 41 is smaller than the circumferential diameter of the inner wall of the protrusion 12, so that the movable gear plate 41 can be embedded in the inner side of the protrusion 12 to rotate, while the stationary gear ring 42 remains stationary with the housing 1.

[0031] The tooth shape of the movable gear plate 41 and the tooth shape of the stationary gear ring 42 are offset (meaning that the number of teeth and the shape of the teeth are different) and mesh with the planetary assembly 43. Figure 3 and Figure 4 It can be seen that the planetary gears 432 in the planetary assembly 43 can mesh with the teeth on the movable gear plate 41 and the stationary gear ring 42 at the same time. Due to the shape of the planetary gears 432 on the stationary gear ring 42, the movable gear plate 41 is driven to rotate at the same time.

[0032] exist Figure 1 As can be seen in the figure, the planetary assembly 43 includes a planetary carrier 431 and planetary gears 432. Three planetary gears 432 are arranged in the circumferential direction of the planetary carrier 431. An annular hole 433 is arranged at the center of the planetary carrier 431, and the annular hole 433 is used for the central gear 44 to be inserted.

[0033] In this solution, a tool slot is provided at the shaft end of the central gear 44. The tool slot is a hexagonal slot 441. Of course, other types of tool slots can also be provided to facilitate the insertion of an electric drill tool or other tool to achieve driving.

[0034] In this solution, the lower part of the housing 1 is detachably connected with a hanging ring 6, and can also be fixedly connected to the hanging ring 6, or universally connected to the hanging ring 6. The universal connection here means that it can rotate in the circumferential direction like a universal wheel. The hanging ring 6 can be used to hang heavy objects, and can generally be tied and fixed with ropes.

[0035] The lifter of this solution can be lifted and lowered by winding the rope. For easy operation, the side wall of the housing 1 is detachably fixed with a friction hook 7. The rope can be wound, bound and slid on the friction hook 7.

[0036] More specifically, a rope pressing wheel 8, a rope guide block 9, and a friction block 5 are installed between the housing 1 and the cover 3. The rope pressing wheel 8 is located on one side of the rope guide block 9 and at the rope inlet, and the friction block 5 is located on the other side of the rope guide block 9 and at the rope outlet. The rope is guided by the rope pressing wheel 8, the friction block 5 guides the rope for sliding, and the rope guide block 9 is also used for guiding the position of the rope.

[0037] In summary, this solution also provides convenient and quick operation in terms of assembly. It can be seen that it is convenient for later maintenance and overhaul. In terms of use, it is safe and reliable, and can be locked by the planetary transmission mechanism 4, that is, the power can only be input by the central gear 44 and drive the rope wheel 2 to rotate, and the rope wheel 2 cannot rotate to drive the central gear 44 to rotate. In this way, the work can be made safer and more reliable. When the heavy object is lifted, in the absence of power input, the rope wheel 2 can be locked to prevent rolling.

[0038] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
