Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transmission rope rotary drive, in particular to a transmission rope rotary drive system. BACKGROUND

[0002] At present, the harvesting method of bamboo is to use the bamboo sliding method to reduce the transportation strength, that is, to use the gravity of the bamboo itself to slide from the top of the mountain to the bottom of the mountain, thereby saving transportation cost. However, the bamboo is easy to collide with people, trees and other objects on the mountain, which hinders the transportation of the bamboo and is prone to danger. The high-altitude transmission method of the bamboo by setting up a rope transmission system between two high lands in the mountainous area can avoid the above problems. The rope transmission structure needs to be provided with a driving system for providing rotary driving force for the transmission rope.

[0003] Chinese patent CN202021858896.4 discloses a chuck structure for driving the winding of a drum type vulcanizing machine, which comprises a transmission shaft, a rotating shaft, a first fixed clutch, a second fixed clutch and a sliding clutch. The transmission shaft and the two ends of the rotating shaft are in close contact with a gap and the axes of the two shafts are coincident. The first fixed clutch and the rolling bearing are sequentially sleeved on one end of the rotating shaft. One end of the transmission shaft is fixedly connected with the second fixed clutch, and the second fixed clutch protrudes outward from the end of the transmission shaft. The second fixed clutch is clamped into the rolling bearing and fixed, and there is a gap between the two fixed clutches. The outer cylindrical surfaces of the two fixed clutches are provided with external teeth, and the inner ring wall of the sliding clutch is provided with internal teeth which can be engaged with the two fixed clutches. The sliding clutch is in contact with a push-pull mechanism, which moves back and forth along the transmission shaft to disconnect the synchronous rotation between the rotating shaft and the transmission shaft.

[0004] For the use occasion of high-altitude transmission of bamboo between mountains, multiple rotary ropes need to be set up, and multiple rotary ropes need to be rotated respectively during the bamboo transmission process and need to change their rotary directions when necessary. In addition, since the bamboo harvesting and transportation system in the mountainous area involves a large structure, a transmission rope rotary drive system corresponding to the large structure needs to be set up to ensure that it has sufficient supporting force. There is a lack of a driving system in the prior art which can drive multiple groups of rotary ropes to rotate forward and backward respectively and can quickly switch the power on and off. SUMMARY

[0056] Embodiment one

[0057] As Figures 1-2As shown, a transmission rope rotation drive system includes: a transmission module 1, which is rotatably mounted on a support 2; a drive module 3, which drives the transmission module 1 to rotate in both directions; a rope winch 4, at least one set of rope winches 4 being coaxially and rotatably mounted on the transmission shaft 11 of the transmission module 1; and a clutch module 5, which is circumferentially fixed and axially slidable coaxially mounted on the transmission shaft 11. Force is applied to the clutch module 5 along the axial direction, and the clutch module 5 slides axially to connect or disconnect from the rope winch 4, thereby establishing and disconnecting the transmission connection between the transmission module 1 and the rope winch 4.

[0058] Preferably, the rope winch 4 is axially limited and circumferentially rotatable and sleeved on the transmission shaft 11 of the transmission module 1.

[0059] Preferably, the clutch module 5 is driven to rotate synchronously by the transmission module 1. When the clutch module 5 is connected to the rope winch 4, it drives the rope winch 4 to rotate synchronously. When the clutch module 5 is separated from the rope winch 4, it will not drive the rope winch 4 to rotate synchronously, which is the idle state.

[0060] In this embodiment, a clutch module 5 is circumferentially limited and axially slidable installed on the transmission module 1, and a rope winch 4 for winding the rotating rope is axially limited and circumferentially rotatable installed on the transmission module 1. While the clutch module 5 is driven by the transmission module 1 to rotate synchronously, it can slide along the axial direction of the transmission module 1 to connect or disconnect with the rope winch 4, thereby establishing and disconnecting the transmission connection between the transmission module 1 and the rope winch 4. By structurally designing the cooperation relationship between the clutch module 5, the transmission module 1, and the rope winch 4, force can be applied to the clutch module 5 from one axial side of the entire system along the axial direction to make the clutch module 5 slide axially, thereby connecting or disconnecting with the rope winch 4, thus realizing the transmission and disconnection of rotational power. The clutch operation is quick and labor-saving, and the sliding action is smooth and prevents jamming, making it particularly suitable for switching cooperation relationships in large equipment.

[0061] Preferably, the support 2 is provided at both ends and the middle of the drive shaft 11.

[0062] As a preferred option, such as Figures 2-4 As shown, the clutch module 5 includes: a dial 51, which is correspondingly arranged with the rope winch 4 and axially slidably mounted on the drive shaft 11; and a push-pull rod 52, in which the drive shaft 11 is hollow, and the push-pull rod 52 is coaxially arranged in the hollow space of the drive shaft 11. The inner circumference of the dial 51 is coaxial and axially fixedly mounted on the push-pull rod 52. Pulling the push-pull rod 52 axially drives the dial 51 to move synchronously.

[0063] It should be noted that the push-pull rod 52 extends out of the transmission shaft 11 at both ends, and the push-pull rod 52 can be pushed and pulled from the axial ends of the entire system during clutch switching operation, so that the force application space is larger and the force is better applied, and especially when manually operated, the operation is more convenient.

[0064] As a preferred, the diameter of the dial wheel 51 is greater than the diameter of the transmission shaft 11, the inner circle of the circumference is located in the hollow space of the transmission shaft 11 to be connected with the push-pull rod 52, and the outer circle of the circumference is located outside the transmission shaft 11 to cooperate with the dial wheel 51.

[0065] As a preferred, as shown in Figures 5-6 The push-pull rod 52 is radially outwardly protruding, and the finger ring 521 is arranged in at least two axially distributed positions, and the limiting groove 522 is formed between the adjacent two finger rings 521, and the dial wheel 51 is correspondingly sleeved in the limiting groove 522.

[0066] As a preferred, as shown in Figure 4 The transmission shaft 11 is axially hollowed out on the circumferential surface to form an insertion piece segment 532 in the remaining part of the hollow segment 531 in the circumferential direction, as shown in Figure 9 The dial wheel 51 is provided with an insertion opening 512, as shown in Figures 7-8 The insertion piece segment 532 is correspondingly inserted into the insertion opening 512, and the length of the insertion piece segment 532 in the axial direction is greater than the thickness of the dial wheel 51 in the axial direction, so that the dial wheel 51 can slide along the length direction of the insertion piece segment 532.

[0067] As a preferred, the insertion piece segment 532 is uniformly arranged in several groups in the circumferential direction of the transmission shaft 11, and the insertion opening 512 is correspondingly arranged with the insertion piece segment 532.

[0068] As a preferred, as shown in Figure 8 The insertion piece segment 532 and the insertion opening 512 form an axial sliding structure 53, which enables the dial wheel 51 to be fixed in the circumferential direction and axially slidingly matched with the transmission shaft 11, and fixedly connected with the push-pull rod 52 in the concentric direction.

[0069] In this embodiment, by setting the drive shaft 11 as a hollow structure and inserting the push-pull rod 52 concentrically inside the drive shaft 11, and by setting an axial sliding structure 53 composed of insert segment 532 and insert 512 between the dial 51 and the drive shaft 11, the dial 51 is circumferentially fixed and axially slidingly engaged with the drive shaft 11, and concentrically fixedly connected with the push-pull rod 52. The structure is ingeniously designed and stable. When the push-pull rod 52 is pushed or pulled from the end, the dial 51 connected to it concentrically slides axially. The sliding force of the clutch module 5 is concentric and coaxial with the clutch module 5, making operation effortless and the force on the clutch module uniform. The sliding action is smooth and stable, avoiding equipment damage.

[0070] In this embodiment, a hollow section 531 is axially cut on the outer circumference of the drive shaft 11 to form an insert segment 532, and a corresponding insertion port 512 is cut on the dial 51. The insertion port 512 is slidably inserted into the insert segment 532, thereby forming an axial sliding structure 53 between the insert segment 532 and the insertion port 512. This axial sliding structure 53 allows the dial 51 to be circumferentially fixed and axially slidingly engaged with the drive shaft 11, and to be concentrically fixedly connected with the push-pull rod 52. The structure is ingeniously designed and stable.

[0071] As a preferred option, such as Figures 3-4 , Figure 7 As shown, the dial 51 has a protruding locking block 511 on the side facing the rope winch 4, and the rope winch 4 has a recessed locking groove 41 on the side facing the dial 51. The locking block 511 can be locked into the locking groove 41 to fix the dial 51 and the rope winch 4 circumferentially.

[0072] In this embodiment, a locking block 511 is protruding on the side of the dial 51 facing the rope winch 4, and a locking groove 41 is recessed on the side of the rope winch 4 facing the dial 51. During the sliding process of the dial 51, the circumferential limiting connection between the dial 51 and the rope winch 4 is achieved through the engagement and cooperation of the locking block 511 and the locking groove 41. The engagement and cooperation method is easy to align and convenient to operate.

[0073] Preferably, several of the card blocks 511 and card slots 41 are arranged in a circumferential array along the dial 51 or the rope winch 4.

[0074] Preferably, the hollow section 531 is matched and locked at the locking block 511, and the insertion port 512 is matched and opened between two adjacent locking blocks 511, so that the transmission shaft 11 and the dial 51 are matched and locked together, and the structure has high stability.

For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0077] As a preferred option, such as Figure 1 As shown, two sets of rope winches 4 are arranged axially on the transmission module 1, and the clutch module 5 is located between the two sets of rope winches 4 and is not connected to the two sets of rope winches 4 at the same time.

[0078] As a preferred option, such as Figure 8 As shown, the drive shaft 11 is configured as a split two-section structure, comprising: a left shaft section 111, a right shaft section 112, and a connecting disc 113 coaxially connecting the left shaft section 111 and the right shaft section 112, as shown.

[0079] In this embodiment, two sets of rope winches 4 are arranged axially on the drive shaft 11, and two sets of dial discs 51 are arranged on the left and right sides between the two sets of rope winches 4. Thus, when the push-pull rod 52 is pushed or pulled, the dial disc 51 on the left can be connected to the rope winch 4 on the left, or the dial disc 51 on the right can be connected to the rope winch 4 on the right, or neither set of dial discs 51 can be connected to the rope winch 4, so that the drive shaft 11 is in an idle state. The structure is ingeniously designed and can share the power to drive the two sets of rope winches 4 to work in a corresponding manner.

[0082] As a preferred option, such as Figure 11 As shown, the transmission module 1 has a horizontally arranged shaft and includes: a transmission shaft 11; and a reversing unit 12. The reversing unit 12 is coaxially fixedly installed at the end of the transmission shaft 11 and drives the transmission shaft 11 to rotate in both directions.

[0083] As a preferred option, such as Figure 12As shown, the reversing unit 12 comprises a transmission gear ring 121, an inner ring of which is provided with teeth; a transmission gear 122, the diameter of which is smaller than that of the transmission gear ring 121 and is coaxially arranged on the inner side of the transmission gear ring 121; and a reversing gear 123, which is arranged in a reversing space 124 formed between the transmission gear ring 121 and the transmission gear 122 and can be engaged with the transmission gear ring 121 or the transmission gear 122.

[0084] As a preference, the diameter of the reversing gear 123 is smaller than the width of the reversing space 124.

[0085] As a preference, as shown, Figure 11 As shown, the driving module 3 comprises a driving part 31, the rotating output end of which is coaxially fixedly connected with the reversing gear 123; and a driving seat 32, on which the driving part 31 is installed, which is linearly movably arranged to switch the engagement position of the reversing gear 123.

[0086] In the embodiment, the transmission module 1 is provided with the coaxially connected transmission shaft 11 and reversing unit 12, which is composed of the inner transmission gear 122, the outer transmission gear ring 121 and the reversing gear 123 between them, the reversing space 124 is formed between the transmission gear ring 121 and the transmission gear 122 for the position activity adjustment of the reversing gear 123, and the driving module 3 connected with the reversing unit 12 is matched and arranged, the rotating driving force is provided by the driving part 31 in the driving module 3, which drives the transmission shaft 11 to rotate through the transmission of the reversing unit 12, the engagement of the reversing gear 123 with the transmission gear 122 or the transmission gear ring 121 is switched through the linear movement adjustment action of the driving seat 32 in the driving module 3, so as to change the forward and reverse rotating directions of the transmission shaft 11, the overall structure of the reversing structure is ingenious and stable, and the switching operation is convenient.

[0087] It should be noted that the transmission gear ring 121 is connected with the transmission shaft 11 through the side plate, and the transmission gear ring 121 and the transmission gear 122 are coaxially installed on one end of the transmission shaft 11.

[0088] As a preference, as shown, Figure 13As shown, the drive seat 32 includes: an upper seat 321 on which the drive unit 31 is mounted, the bottom end of the upper seat 321 being rotatably connected to an upper stud 322; a lower stud 323 coaxially disposed below the upper stud 322; and a threaded sleeve 324, the threaded sleeve 324 being coaxially disposed between the upper stud 322 and the lower stud 323, the inner wall of the threaded sleeve 324 being threaded, the opposite ends of the upper stud 322 and the lower stud 323 being screwed to the threaded sleeve 324 respectively, and a limiting seat 325 for limiting its rotation is sleeved on the upper seat 321.

[0089] In a preferred embodiment, the drive seat 32 is vertically arranged and its length is adjustable in the vertical direction via a threaded structure, and the reversing gear 123 is located at the upper or lower end of the transmission gear 122.

[0090] When switching adjustments, rotating the screw sleeve 324 clockwise causes the upper stud 322 and the lower stud 323 to move closer together, thereby shortening the length of the drive seat 32 and lowering the height of the drive unit 31 and the reversing gear 123 until the reversing gear 123 meshes with the transmission gear ring 121. At this time, the drive unit 31 drives the transmission shaft 11 to rotate clockwise. Rotating the screw sleeve 324 counterclockwise causes the upper stud 322 and the lower stud 323 to move further apart, thereby lengthening the length of the drive seat 32 and raising the height of the drive unit 31 and the reversing gear 123 until the reversing gear 123 meshes with the transmission gear 122.
