Description

Technical Field

[0001] This utility model relates to the field of winch technology, and in particular to a high-lift, ultra-large built-in planetary winch for high-altitude areas. Background Technology

[0002] Under ultra-high head and heavy load conditions, the winch drum needs to withstand extremely high radial loads and torques. Traditional winches typically support the drum directly on the base via large bearings and are driven by an external gearbox through a coupling. Existing technology features long transmission chains and a non-compact structure, resulting in bulky and heavy equipment, which is extremely disadvantageous for high-altitude areas with demanding transportation and installation conditions. The large support span of the drum makes it prone to bending deformation under heavy loads, affecting gear meshing accuracy, accelerating wear, and causing uneven cable winding, tangling, or even cable slippage. Furthermore, the traditional integrated drum and support structure is extremely inconvenient to maintain; if bearings or transmission components are damaged, the entire unit must be disassembled, which is time-consuming and labor-intensive. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problems in the prior art where the support span of the drum is large, it is easy to bend and deform under heavy load, which affects the gear meshing accuracy, aggravates wear, and leads to uneven winding of steel cables, tangled ropes, or even jumping out of the groove, a high-lift ultra-large built-in planetary winch for high-altitude areas is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a high-lift, ultra-large built-in planetary winch for high-altitude areas, including a base, a motor, a planetary reduction mechanism, a drum and mounting components. The motor and the base are fixedly connected, and the output end of the motor and the input end of the planetary reduction mechanism are connected by transmission. The motor is used to provide power for the rotation of the drum. The mounting components include a connecting seat, a mounting base, and a connecting shaft. The mounting base and the base are fixedly connected, and the connecting shaft and the mounting base are rotatably connected. The drum is sleeved on the connecting shaft and is rotatably connected to the connecting shaft. The output end of the planetary reduction mechanism is drivenly connected to the connecting seat, and the connecting seat and the drum are fixedly connected. The output end of the planetary reduction mechanism is directly integrated with the connecting seat, and the drum is then fixed to the connecting seat to form a modular transmission unit. This makes the overall structure very compact and the weight distribution more reasonable, making it particularly suitable for high-altitude applications where space and weight are sensitive. The first rotating joint is formed between the drum and the connecting shaft, which bears the huge radial working load of the drum and allows the drum to rotate relative to the connecting shaft. The second rotating joint is formed between the connecting shaft and the mounting base, which bears the radial load of the connecting shaft itself and allows it to rotate freely. Its load is relatively small and stable, which can effectively resist the extrusion deformation and bending deformation of the drum under heavy load, ensure the roundness of the drum, and thus ensure that the steel rope can be tightly and neatly wound, preventing rope tangling and skipping.

[0005] To address the issue of steel cables easily detaching from the drum or becoming disorganized during ultra-high capacity winding, a further improvement is made by protruding two spaced baffles on the drum, with a winding zone formed between the two baffles for winding the steel cables.

[0006] To address the challenges of hoisting, moving, and positioning heavy-duty drums during on-site installation, as well as the issues of small connection area and insufficient connection strength between the drum and the connecting seat, a further improvement is made to the design where the end of the baffle near the connecting seat on the drum is bent towards the direction of the connecting seat to form a gripping part.

[0007] To address the issues of difficulty in quickly and accurately aligning the free end of the drum during installation, and the potential for wobbling or uneven wear due to gaps during operation, the system further includes a section where the end of the baffle on the drum near the mounting base is bent towards the connecting base to form a mating part. The mounting base has a mating groove that matches the mating part, and the mating part is arranged within the mating groove.

[0008] To address the issue that external mating alone may not be sufficient to resist localized drum deformation caused by heavy loads, a further installation component is included, comprising a support member mounted on the connecting shaft, with the support member contacting the inner ring of the mating section.

[0009] The device further includes a planetary reduction mechanism comprising a housing, a sun gear, an internal gear ring, a planet carrier, and at least three planet gears. The internal gear ring is fixedly connected to the housing, and the housing is fixedly connected to the base. The planet gears are arranged around the sun gear circumferentially and mesh with both the sun gear and the internal gear ring. The sun gear and the internal gear ring are coaxially arranged, with the sun gear located at the center of the internal gear ring. The output shaft of the motor is driven by the sun gear. The planet gears are arranged on the planet carrier, and the planet carrier is fixedly connected to the connecting seat.

[0010] The beneficial effects of this utility model are: This utility model provides a high-lift, ultra-large built-in planetary winch for high-altitude areas, which directly integrates the output end of the planetary reduction mechanism with the connecting seat, and then fixes the drum to the connecting seat to form a modular transmission unit, making the whole machine structure very compact and the weight distribution more reasonable, which is particularly suitable for high-altitude application scenarios that are sensitive to space and weight. The first rotating joint is formed between the drum and the connecting shaft, which bears the huge radial working load of the drum and allows the drum to rotate relative to the connecting shaft. The second rotating joint is formed between the connecting shaft and the mounting base, which bears the radial load of the connecting shaft itself and allows it to rotate freely. Its load is relatively small and stable, which can effectively resist the extrusion deformation and bending deformation of the drum under heavy load, ensure the roundness of the drum, and thus ensure that the steel rope can be tightly and neatly wound, preventing rope tangling and skipping.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1 This is a structural schematic diagram of the present invention. A high-lift, ultra-large built-in planetary winch for high-altitude areas includes a base 1, a motor 2, a planetary reduction mechanism 3, a drum 4, and an installation assembly 5. The motor 2 and the base 1 are fixedly connected. The output end of the motor 2 is connected to the input end of the planetary reduction mechanism 3. The motor 2 is used to provide power for the rotation of the drum 4. Mounting assembly 5 includes a connecting seat 51, a mounting seat 52, and a connecting shaft 53. The mounting seat 52 is fixedly connected to the base 1, and the connecting shaft 53 is rotatably connected to the mounting seat 52. The drum 4 is sleeved on the connecting shaft 53, and the drum 4 is rotatably connected to the connecting shaft 53. The output end of the planetary reduction mechanism 3 is connected to the connecting seat 51 for transmission. The connecting seat 51 and the drum 4 are fixedly connected. The output end of the planetary reduction mechanism 3 is directly integrated with the connecting seat 51, and the drum 4 is then fixed to the connecting seat 51 to form a modular transmission unit. This makes the whole machine structure very compact and the weight distribution more reasonable, making it particularly suitable for high-altitude application scenarios that are sensitive to space and weight. The first rotating pair is formed between the drum 4 and the connecting shaft 53, which bears the huge radial working load of the drum 4 and allows the drum 4 to rotate relative to the connecting shaft 53. The second rotating pair is formed between the connecting shaft 53 and the mounting base 52, which bears the radial load of the connecting shaft 53 itself and allows it to rotate freely. Its load is relatively small and stable, which can effectively resist the extrusion deformation and bending deformation of the drum 4 under heavy load, ensure the roundness of the drum 4, and thus ensure that the steel rope can be tightly and neatly wound, preventing rope tangling and skipping.

[0016] like Figure 1 , 2As shown, two spaced baffles 41 protrude from the drum 4, forming a winding area between the two baffles 41 for winding the steel cable. The two baffles 41 form a clear winding area, effectively constraining the steel cable and ensuring that it is wound neatly and in layers, thereby improving safety and reliability.

[0017] like Figure 1 , 2 As shown, the end of the baffle 41 near the connecting seat 51 on the drum 4 is bent in the direction of the connecting seat 51 to form a gripping part 42. The gripping part 42 provides a dedicated force point for the hoisting equipment, making the installation and handling of the drum 4 safe and convenient.

[0018] like Figure 1 , 2 As shown, the end of the baffle 41 on the drum 4 near the mounting base 52 is bent towards the connecting base 51 to form a docking part 43. The mounting base 52 has a docking groove 521 that matches the docking part 43. The docking part 43 is arranged in the docking groove 521. The cooperation between the docking part 43 and the docking groove 521 constitutes a precise axial and radial positioning structure, which realizes the quick centering and installation of the free end of the drum 4 and effectively suppresses the shaking during operation.

[0019] like Figure 1 , 2 As shown, the mounting component 5 includes a support member 54, which is mounted on the connecting shaft 53. The support member 54 contacts the inner ring of the docking part 43. The support member 54 provides direct and adjustable support from inside the docking part, which greatly enhances the local stiffness and deformation resistance of the free end of the drum 4 and forms a reinforced support that combines internal and external docking structures.

[0020] like Figure 1 , 2 As shown, the planetary reduction mechanism 3 includes a housing 31, a sun gear 32, an internal gear ring 33, a planet carrier 34, and at least three planet gears 35. The internal gear ring 33 is fixedly connected to the housing 31, and the housing 31 is fixedly connected to the base 1. The planet gears 35 are arranged around the sun gear 32 in the circumferential direction and mesh with both the sun gear 32 and the internal gear ring 33. The sun gear 32 and the internal gear ring 33 are coaxially arranged, with the sun gear 32 located at the center of the internal gear ring 33. The output shaft of the motor 2 is connected to the sun gear 32 for transmission. The planet gears 35 are arranged on the planet carrier 34, and the planet carrier 34 is fixedly connected to the connecting seat 51. The planetary reduction mechanism 3 naturally has the advantages of compact structure, high load distribution, and large reduction ratio. The output end of its planet carrier 35 provides a large-diameter, high-rigidity mounting surface, which is very suitable for fixed connection with the connecting seat 51, thereby realizing efficient and smooth power transmission to the drum 4.

[0021] Working process: First, using the gripping part 42 on the drum 4, the drum 4 is lifted smoothly by external hoisting equipment and moved to the installation position. This process is safe and reliable, and it is convenient for operators to position the drum. The drum 4 is aligned and fixedly connected with the connecting seat 51 that is fixed on the planetary carrier 34. The docking part 43 at the other end of the drum 4 is slowly lowered into the docking groove 521 of the mounting seat 52 to achieve rapid and accurate radial positioning. Then, the connecting shaft 53 and the support 54 are installed to complete the internal support of the free end of the drum. The motor 2 is started, and the power is reduced and increased in torque by the planetary reduction mechanism 3, and then drives the drum 4 to rotate through the connecting seat 51. The drum 4 runs smoothly under the stable support at both ends, winding and unwinding the steel cable. The baffle 41 ensures that the steel cable is wound in an orderly manner.

[0022] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
