Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rope climbing machines, in particular to a rope winding drive mechanism with face gears. BACKGROUND

[0002] At present, the motor output shaft and the winding wheel of the rope winding drive mechanism need to rely on the gearbox mechanism to reduce speed and increase torque. For example, the Chinese patent with publication (announcement) number CN216895690U discloses a driving device for a rope climbing machine. It is known that the output shaft of the motor and the shaft of the winding wheel are kept parallel. Therefore, the overall structural layout makes the winding wheel have a larger inclination after the rope is wound on the winding wheel and the hook hangs the weight under the gravity distribution of this layout. Because the motor is a cylindrical structure and the motor is transversely parallel to the axis of the winding wheel, the center of gravity is not easy to adjust to the vertical position of the rope body, and the transmission reliability and convenience are not enough.

[0003] In order to solve the problem of how to improve the driving reliability and use convenience of the rope winding operation, the above structure needs to be improved. CONTENT OF THE UTILITY MODEL

Those skilled in the art can easily understand other advantages and effects of this invention from the content disclosed in this specification. This invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be changed at will, and the layout of the components may also be more complex.

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example:

[0029] This invention discloses a rope winding drive mechanism with a face gear, as described in the following embodiment. Figure 1 and Figure 2As shown, the assembly includes a mounting plate 1, a motor 2, a reversing gearbox 3, a rope reel 4, and a hook 5. The rope reel 4 and the hook 5 are located on the same side of the mounting plate 1 and maintain the same vertical position (this description is based on the posture in use, which can be referenced). Figure 1 The motor 2 and the reversing gearbox 3 are located on the other side of the mounting plate 1. The output shaft of the motor 2 remains vertical and drives the winding wheel 4 through the reversing gearbox 3.

[0030] refer to Figure 3 , Figure 4 and Figure 5 As shown, the reversing gearbox 3 includes a housing 31, a face gear 32, a mating shaft 33, and a planetary drive mechanism 34. The mating shaft 33 is mounted on the lower part of the housing 31 via a first bearing 61, and the mating shaft 33 is used to fix with the output shaft of the motor 2. The sun gear shaft 341 of the planetary drive mechanism 34 is mounted on the side of the housing 31 via a second bearing 62. The face gear 32 is fixed to the sun gear shaft 341 by a key connection and meshes with the mating shaft 33. The output shaft of the planetary drive mechanism 34 passes through the mounting plate 1 and is fixed with the winding pulley 4. The axes of the output shaft of the motor 2 and the winding pulley 4 are in the same plane and perpendicular to each other.

[0031] Specifically, in combination Figure 3 and Figure 5 The housing 31 includes a base 311, a rear cover 312, and a front cover 313. A second bearing 62 is mounted on the rear cover 312, which is fixed to one side of the base 311. The front cover 313 is fixed to the other side of the base 311. A third bearing 63 is mounted in the middle of the sun gear shaft 341. This structure allows for easy and simple maintenance by removing the rear cover 312 for internal inspection. The presence of the third bearing 63 in the middle of the sun gear shaft 341 ensures smoother transmission and more stable rotation. With the support of the third bearing 63 and the second bearing 62, it maintains a reliable horizontal position, and its axis is coaxial with the winding pulley 4.

[0032] Specifically, the planetary drive mechanism 34 includes a gear ring 342, a sun gear shaft 341, planetary gears 343, and a planet carrier 344. The gear ring 342 has a slot 345 on its side and is fixed to the rear cover 312. The planet carrier 344 is fitted with the planetary gears 343. A rope output shaft 346 is located on one side of the planet carrier 344, and a fourth bearing 64 is mounted on the rope output shaft 346. The third bearing 63 provides stable support for the planet carrier 344, allowing the rope output shaft 346 to move more smoothly and ensuring it is aligned with the rope reel 4 on the same axis.

[0033] In this design, a brake 21 is installed at the tail of motor 2. This effectively brakes motor 2, thereby preventing the rope reel 4 from slipping.

[0034] To ensure more stable operation of the reversing gearbox 3, mounting plate 1 is fixed to the rear end cover, thus making the assembly more secure.

[0035] In this design, a rope guide assembly 7 is mounted on the mounting plate 1 on the same side as the rope reel 4. The rope guide assembly 7 includes mounting bolts 71, rope guide wheels 72, and connecting seats 73. Both ends of the connecting seats 73 are fixed to the mounting plate 1 by mounting bolts 71. A rope guide wheel 72 is rotatably mounted on each mounting bolt 71. A rope guide plate 110 is positioned between two rope guide wheels 72 and fixed to the mounting plate 1. This structural design makes it very convenient to install the rope 120 onto the rope reel 4. It can pass directly between the two rope guide wheels 72 and be looped onto the rope reel 4. The rope reel 4 can drive the rope 120, thus enabling the mechanism to move and climb on the rope 120. When a heavy object is hooked onto the hook 5, the lifting and lowering operation of the goods can be performed.

[0036] To prevent the rope 120 from detaching from the winding wheel 4, a rope box 8 is fixed to the mounting plate 1. A cover 9 is rotatably connected to one side of the rope box 8. The inner wall of the cover 9 is provided with a limiting groove 91 that matches the winding wheel 4. The cover 9 and the rope box 8 are fixed together by a buckle 92. This structure effectively protects the winding wheel 4 and prevents the rope 120 from detaching from it.

[0037] Therefore, the working principle of the scheme in this application is as follows: Figure 6 As can be seen, the motor 2 is installed vertically. The vertical mounting of the motor 2's cylindrical structure significantly reduces the horizontal lever arm (L1). Simultaneously, the meshing transmission of the face gear 32 and the mating shaft 33 changes the driving direction of the motor 2, allowing the rope winding wheel 4 to continue operating. Combined with the planetary drive structure, this enables deceleration and increases torque, effectively improving the overall rope winding lifting capacity and reliability. In this design, the first bearing 61, second bearing 62, third bearing 63, and fourth bearing 64 ensure transmission reliability, reduce transmission noise and vibration, extend service life, and prolong operation. This structure facilitates maintenance and repair, allowing for repairs on the left and right sides of the mounting plate 1, resulting in high disassembly and assembly efficiency, and simple and easy assembly, thus facilitating production.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the scope of the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent changes made to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
