Description

Technical Field

[0001] The utility model relates to the technical field of winch auxiliary equipment, in particular to a device that can facilitate the automatic rope laying work of a hydraulic winch. Background Art

[0002] A hydraulic winch is a lifting device that drives a drum to rotate through a hydraulic transmission device and winds a cable such as a steel wire rope or a chain on the drum to lift or tow heavy objects. Due to its advantages such as simple and reliable operation and convenient movement, it is widely used in various industries such as construction and water conservancy. During the rope winding process, in order to avoid the overlap or looseness of the cable caused by uneven arrangement, which may lead to cable wear or even deformation and bending, the cable usually needs to be arranged neatly and tightly on the drum.

[0003] For this reason, in the prior art, there is a rope laying device disclosed in a Chinese utility model patent "A Rope Laying Device for a Winch" with the patent number CN202322352927.9 (publication number CN220664736U). This rope laying device drives a lead screw to rotate through an independent drive motor, so that while the drum rotates, the moving block on the lead screw can also drive the rope laying assembly to move along the axial direction of the drum, and the rope laying assembly can play a role in guiding the cable, thus completing the rope laying process.

[0004] However, the existing rope laying device still has certain defects in the use process. Specifically: the existing rope laying device drives the rope laying assembly to move through an independent drive source such as a motor, while the drum is driven by another drive source. Therefore, a total of two drive sources are required to drive the rope laying assembly and the drum respectively, and the rope laying assembly and the drum operate independently of each other. Once a failure such as jamming occurs in the rope laying assembly or the drum, resulting in an error in the rope winding angle, the cable will still be unevenly arranged on the drum. Therefore, further improvement of the existing rope laying device is still needed. Summary of the Utility Model

The conversion part is set to be cylindrical in order to facilitate steering when moving to the end of the reciprocating screw, and in order to make the steering more flexible and durable, bearings and other components can also be provided on the periphery of the conversion part according to actual needs.

[0013] In order to prevent the moving part from rotating with the power input shaft, preferably, a limit rod parallel to the power input shaft is provided on the moving mechanism, and a through hole for the limit rod to pass through is provided on the moving part, and the limit rod limits the moving part to move only in a straight line.

[0030] The present utility model will be further described in detail below in conjunction with specific embodiments.

[0031] As Figures 1 to 8 shown, it is a preferred embodiment of the present utility model. As Figure 1 shown, the rope arranging device for a hydraulic winch in this embodiment is installed on the base 1 of the hydraulic winch, and includes a rope arranging mechanism 2 located on one radial side of the drum 11 for guiding the rope A to be arranged. A moving mechanism 3 parallel to the axis X of the drum 11 is connected to the rope arranging mechanism 2. It also includes a transmission mechanism 4 located on one axial side of the drum 11. The transmission mechanism 4 can connect the drive source 12 of the drum 11 and the moving mechanism 3, so that when the drum 11 rotates, the moving mechanism 3 can synchronously drive the rope arranging mechanism 2 to move along the axial direction of the drum 11. With such a design, on the one hand, it can rely on only one drive source 12 to drive the drum 11 and the rope arranging mechanism 2 at the same time, and on the other hand, it can also improve the synchronization between the drum 11 and the rope arranging mechanism 2. For example, even if one of them gets stuck, the other will also get stuck correspondingly, so that the arrangement of the rope A to be arranged on the drum 11 is more neat.

[0032] In order for the transmission mechanism 4 to transmit the power output by the drive source 12 to the moving mechanism 3, the transmission mechanism 4 in this embodiment further includes a first transmission member 41 connected to the power output shaft 13 of the drive source 12, and a second transmission member 42 connected to the power input shaft 31 of the moving mechanism 3. The first transmission member 41 and the second transmission member 42 are connected. And the drive source 12 in this embodiment is a housing-rotating reducer, the housing of the drive source 12 can rotate and is connected to the drum 11, and the power output shaft 13 extends from the housing. In order to connect the first transmission member 41 and the second transmission member 42, the first transmission member 41 in this embodiment is a sprocket structure. Correspondingly, the second transmission member 42 is a sprocket structure adapted to the first transmission member 41, and the first transmission member 41 and the second transmission member 42 are connected by a chain 43. The transmission mechanism 4 is set in the form of chain drive, considering that chain drive has high load-bearing capacity, accurate transmission ratio, large size range, and is also suitable for harsh working environments. In addition, a protective cover is provided on the periphery of the transmission mechanism 4, but this structure is relatively conventional, so it is not drawn and described in the drawings. Further, referring to Figures 2 to 4 In order to connect the first transmission member 41 to the power output shaft 13 and the second transmission member 42 to the power input shaft 31, the base 1 in this embodiment further includes a first side wall 14 and a second side wall 15 for installing the drum 11. The power input shaft 31 extends from the first side wall 14 towards the second side wall 15 and at least partially passes through the second side wall 15 to be connected to the second transmission member 42. Similarly, the power output shaft 13 at least partially passes through the second side wall 15 to be connected to the first transmission member 41.

[0033] Further, in order to drive the rope arranging mechanism 2 to move linearly along the axial direction of the drum 11, the moving mechanism 3 further includes a moving member 32 located on the power input shaft 31, and a conversion member 33 connected to the power input shaft 31 is provided on the moving member 32. The conversion member 33 can convert the rotational power of the power input shaft 31 into linear power. In order to achieve the reciprocating movement of the moving member 32 when the rotation direction of the power input shaft 31 remains unchanged, as Figure 5 , Figure 7 , Figure 8 shown, the power input shaft 31 in this embodiment is a reciprocating lead screw. Correspondingly, the conversion member 33 is cylindrical and extends from the moving member 32 towards the thread structure 311 of the power input shaft 31, and abuts against the thread structure 311 to form a mating end 331. A mating portion 332 adapted to the thread structure 311 is provided on the mating end 331. The conversion member 33 is commonly known as a "lever". The conversion member 33 is set to be cylindrical to facilitate steering when moving to the end of the reciprocating lead screw. In order to make the steering more flexible and durable, a bearing is further provided on the outer periphery of the conversion member 33. In order to prevent the moving member 32 from rotating with the power input shaft 31, a limiting rod 34 parallel to the power input shaft 31 is provided on the moving mechanism 3, and a through hole 321 for the limiting rod 34 to pass through is formed on the moving member 32. The limiting rod 34 restricts the moving member 32 to move only linearly. The limiting rod 34 in this embodiment is cylindrical and cooperates with the power input shaft 31 to jointly limit the moving member 32.

[0034] Finally, in order to guide the rope A to be arranged, the rope arranging mechanism 2 further includes at least two guide wheels 21 provided on the moving member 32, and a gap 22 for the rope A to be arranged to pass through is formed between the guide wheels 21. The rope arranging mechanism 2 in this embodiment includes two guide wheels 21, and further includes mounting plates 23 corresponding to the guide wheels 21 one by one, thereby connecting the guide wheels 21 and the moving member 32, as Figure 6As shown, at least a part of the mounting plate 23 protrudes to form a rotating shaft 231 through which the guide wheel 21 passes. The guide wheel 21 can rotate around the corresponding rotating shaft 231, and the upper ends of the two rotating shafts 231 are connected by a limiting plate 24. The limiting plate 24 is provided to close the opening above the gap 22 to prevent the to-be-arranged cable rope A from slipping out. In order to enable the rope arranging mechanism 2 to adapt to different specifications of the to-be-arranged cable rope A, a first connecting member 232 for connecting the mounting plate 23 and the moving member 32 is provided on the mounting plate 23, and a first waist-shaped hole 233 for the first connecting member 232 to pass through is formed. Correspondingly, a second connecting member 241 for connecting the limiting plate 24 and the rotating shaft 231 is provided on the limiting plate 24, and a second waist-shaped hole 242 for the second connecting member 241 to pass through is formed. With such a design, the first connecting member 232 can move within the first waist-shaped hole 233. Similarly, the second connecting member 241 can move within the second waist-shaped hole 242, so that the two guide wheels 21 can move relative to each other as needed to change the size of the gap 22.

[0035] The specific working process of the rope arranging device in this embodiment is as follows:

[0036] As Figure 9 shown, at this time the gap 22 is in the first state. If the specification of the to-be-arranged cable rope A is too large, the size of the gap 22 needs to be adjusted through the first waist-shaped hole 233 in the mounting plate 23 and the second waist-shaped hole 242 in the limiting plate 24; see Figure 10 , at this time the gap 22 is in the second state. Obviously, compared with Figure 9 , Figure 10 the gap 22 is larger. In addition, see Figure 11 , at this time the rope arranging device is in the first state, and the to-be-arranged cable rope A has not completed one layer on the drum 11; as Figure 12 shown, as the drum 11 rotates and the rope arranging mechanism 2 moves, the rope arranging device enters the second state. At this time, the to-be-arranged cable rope A just finishes one layer on the drum 11. Since the power input shaft 31 is a reciprocating lead screw, the conversion member 33 starts to move in the reverse direction in cooperation with the thread structure 311.
