Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to a tooling for winding and unwinding heavy-duty crane wire ropes. Background Technology

[0002] Marine cranes are special cranes used in marine environments for transport operations, primarily for important tasks such as cargo transfer between ships, replenishment at sea, and deployment and retrieval of underwater equipment. Ordinary marine cranes use specially designed and manufactured rope winches for field testing of wire rope deployment and retraction. However, heavy-duty marine cranes have wire rope drums with diameters exceeding 2 meters and lengths exceeding 2.5 meters, with a combined weight of over 5 tons including the wire rope. Therefore, their specially designed rope winches are extremely large.

[0003] Furthermore, the existing technology of using a central shaft to drive a large wire rope drum is also unsuitable. For example, application number CN201310143859.3 discloses a drum device for automatically winding and unwinding cables. This device includes a large gear at the drum end, a drum, and an explosion-proof junction box mounted on the drum shaft. The explosion-proof junction box is fixedly connected to a bearing seat on one side and contains a slip ring, an AC contactor, and a circuit breaker. An encoder is installed at the end of the drum shaft. The drum and the large gear at the drum end are coaxially fixedly connected, and the large gear at the drum end meshes with a small gear at the motor end for transmission. Gear guards are installed on the outer surfaces of both the large gear at the drum end and the small gear at the motor end. The small gear at the motor end is coaxially connected to an AC asynchronous motor via a torque sensor. The AC asynchronous motor, encoder, torque sensor, AC contactor, and circuit breaker are all connected to an explosion-proof motor control box. The winding effect of this device, which uses a central shaft to drive a large wire rope drum, is poor.

[0004] In view of the above, it is necessary to propose a tooling for winding and unwinding the wire rope of a heavy-duty crane to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems by providing a tooling for winding and unwinding heavy-duty crane wire ropes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tooling for winding and unwinding heavy-duty crane wire rope, comprising a wire rope drum and roller frames, wherein the roller frames are symmetrically arranged at the bottom of both ends of the wire rope drum, and the wire rope drum is tactilely connected to the roller frames on both sides; a steel pipe shaft is inserted into the shaft hole of the wire rope drum, and weight structures are suspended at both ends of the steel pipe shaft, wherein the weight structures are combined and adjustable to meet the needs of wire rope drums of different specifications.

[0007] Furthermore, the roller frame includes a longitudinal beam, with V-shaped clamp-like supports hinged at both ends of the longitudinal beam. Support wheels are rotatably connected to both ends of the clamp-like supports, and the support wheels are tumbledly connected to the wire rope drum. Two sets of roller frames are symmetrically arranged at the bottom of the wire rope drum, and a rope arranging mechanism and a brushing mechanism are provided between the two sets of roller frames. The rope arranging structure is used to neatly wind and arrange the wire rope on the wire rope drum, and the brushing mechanism is used to clean the surface of the wound wire rope.

[0008] Furthermore, the rope-laying mechanism includes a guide frame structure that reciprocates between the two longitudinal beams to guide the wire rope, and a chain drive mechanism that drives the guide frame structure to move. The chain drive mechanism changes the travel distance of the guide frame structure as the distance between the two longitudinal beams changes.

[0009] Furthermore, the rope-laying mechanism includes a first crossbeam fixedly disposed on the side of the first longitudinal beam and a second crossbeam fixedly disposed on the side of the second longitudinal beam; the chain transmission mechanism includes guide sprockets rotatably connected to both ends of the first crossbeam, return sprockets rotatably connected to both ends of the second crossbeam, and a transmission chain. The first crossbeam and the second crossbeam are parallel to each other and close to each other, and the first crossbeam slides through the second longitudinal beam. The transmission chain passes around the guide sprocket at the far end of the first crossbeam and passes around the two return sprockets in sequence in an S-shape. The transmission chain between the return sprocket in the second crossbeam and the guide sprocket in the first crossbeam forms a drive chain that drives the guide frame structure to reciprocate.

[0010] Furthermore, the guide frame structure also includes a guide rod fixedly connected to the side of the first longitudinal beam. The guide rod is parallel to the first crossbeam and passes through the second longitudinal beam and is slidably connected. It also includes a moving platform, which is slidably sleeved on the guide rod. The drive chain is fixedly connected to the moving platform. A guide ring is fixedly provided on the upper surface of the moving platform. There are two guide rings. The line connecting the two guide rings is parallel to the first longitudinal beam. One side of the guide ring is provided with a side opening for the steel wire rope to enter.

[0011] Furthermore, the brushing mechanism is mounted on the moving platform and located between two guide rings; the brushing mechanism includes a drive shaft, a mounting bracket, a brush ring, and a transmission structure; the drive shaft is arranged parallel to the guide rod and one end is rotatably connected to the first longitudinal beam, the drive shaft has a keyway along the axial direction, the drive shaft passes through the moving platform for connection with the transmission structure, the mounting bracket is fixedly mounted on the moving platform, the mounting bracket has an upward-facing U-shaped opening, the brush ring is rotatably connected in the U-shaped opening, the brush ring is coaxially arranged with the arcuate bottom wall of the U-shaped opening; the brush ring is cylindrical, the side wall of the brush ring has an axial opening for inserting a steel wire rope, and the transmission structure is used to transmit the power of the drive shaft to drive the brush ring to rotate.

[0012] Furthermore, the transmission structure includes a sliding gear, a positioning gear, and a vertical shaft rotatably connected within the mounting frame. The positioning gear is rotatably connected inside the mounting frame. An external gear is provided on the outer circumference of the brush ring. Four positioning gears are provided and meshed around the external gear.

[0013] The vertical shaft is perpendicular to the axis of the sliding gear. There are two vertical shafts respectively located inside the two sides of the U-shaped opening. The vertical shaft is used to drive the two positioning gears on the same side to rotate, so that the four positioning gears mesh at the same time to drive the brush ring to rotate.

[0014] The sliding gear is slidably sleeved on the drive shaft, and its inner wall has a protruding key that matches the keyway. The sliding gear synchronously drives the two vertical shafts to rotate.

[0015] Furthermore, the inner wall of the brush ring is provided with a detachable and replaceable bristle section.

[0016] Furthermore, the steel pipe shaft is provided with a rotation limiting structure that is rotatably connected to the shaft hole. The rotation limiting structure includes a positioning bushing and a bearing. The positioning bushing is sleeved on the steel pipe shaft. The positioning bushing is provided with an annular flange. The bearing is sleeved on the inner side of the annular flange. The outer ring of the bearing is in contact with the shaft hole. The diameter of the annular flange is larger than the outer diameter of the bearing. A positioning screw is screwed through the positioning bushing radially.

[0017] Furthermore, the weight structure is rectangular with two protruding plugs on the upper surface and a recessed pin on the lower surface that mates with the plugs. The weight structure is inserted into the pin by a steel cable and suspended on a steel pipe shaft.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention provides a shipyard wire rope winding and unwinding fixture for heavy-duty marine cranes. The device has a reasonable structure, is easy to install, and readily available materials for replacement. By installing a roller frame at the bottom of an existing wire rope drum, the fixture rests on the roller frame using the weight of weights and the drum's own weight. The wire rope is wound and unwound by the direct friction between the roller frame and the drum's rim. Furthermore, the weights are designed to be modular and adjustable, accommodating wire rope drums of different specifications. This invention features a rigorous structure, reasonable layout, ease of use, and low manufacturing cost, meeting the market demand for this type of work.

[0020] 2. The weight structure is modular, with different numbers of modules allowing for varying weights. All weights feature identical dovetail grooves (pins and plugs), ensuring interchangeability. This structure accommodates wire rope drums of different specifications while also increasing the overall stability of the fixture.

[0021] 3. The distance between the two roller frames is adjustable, which is convenient for placing steel wire rope drums of different lengths and sizes. The rope arranging mechanism is used to arrange the wound steel wire rope in an orderly manner. In addition, the travel of the guide frame structure in the rope arranging mechanism of this device will automatically change in accordance with the distance between the roller frames. In contrast, the travel of the existing rope arranging mechanism is fixed, which is not conducive to rapid adjustment.

[0022] 4. The brushing mechanism that moves with the guide frame structure can effectively clean the wound wire rope by brushing it around. It can remove the debris and rust attached to the surface. It can also add an oiling roller inside the brush ring to apply oil after brushing, so as to facilitate the simultaneous maintenance of the wire rope during winding and unwinding.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1:

[0034] A tooling for retracting and extending the wire rope of a heavy-duty crane, such as Figure 1 As shown, the device includes a wire rope drum 1 and roller frames. The roller frames are symmetrically arranged at the bottom of both ends of the wire rope drum. The wire rope drum 1 is rotatably connected to the roller frames on both sides, and the roller frames serve as the rotation drive mechanism for the wire rope drum 1. A steel pipe shaft 3 is inserted into the shaft hole of the wire rope drum. Weight structures 4 are suspended at both ends of the steel pipe shaft 3. The weight structures 4 are combined and adjustable structures to meet the needs of wire rope drums of different specifications. Figure 8 As shown, the weight structure 4 is rectangular in shape, with two protruding plugs 38 on the upper surface and a recessed pin 39 on the lower surface that mates with the plugs 38. The weight structure 4 is inserted into the pin 39 via a steel cable and suspended from the steel pipe shaft 3. The weight is a modular design, with different numbers of modules allowing the tooling to have different weights. The modules are available in 1-ton, 2-ton, and 3-ton versions, all with the same dovetail groove for interchangeability. This structure allows for the use of wire rope drums of different specifications while also increasing the overall stability of the tooling.

[0035] It should be ensured that the steel cable pulls the weight a short distance off the ground. Through theoretical calculations, increasing the weight of the rope-reeling device can increase the friction between the roller frame and the ground, thus avoiding the dangerous situation where the traction force pulls the roller frame.

[0036] Both roller frames employ a self-powered structure commonly used in existing technology, such as... Figure 1As shown, the roller frame includes a longitudinal beam, with V-shaped clamp-like supports 7 hinged at both ends of the longitudinal beam. Support wheels 8 are rotatably connected to both ends of the clamp-like supports 7, and the support wheels 8 are tactilely connected to the wire rope drum. Two sets of roller frames are symmetrically arranged at the bottom of the wire rope drum 1, each set supporting both ends of the drum. The automatic drive of these roller frames powers the rotation of the support wheels 8, thereby controlling the rotation of the wire rope drum 1 to achieve the winding or unwinding of the wire rope. It should be noted that the weights... The bottom of component 4 is suspended, with a gap between it and the deck, so that the entire weight is applied to the wire rope drum; there is a large gap between the steel pipe shaft 3 and the shaft hole of the wire rope drum, so that the steel pipe shaft 3 does not rotate with the drum; there is a large gap between the steel pipe shaft 3 and the cable sleeve for hanging weights, so that the cable sleeve does not rotate with the steel pipe during use; the roller frame does not need to be welded to the deck, thus giving the device good mobility. The device relies on the friction generated by the weight of the entire tooling to prevent the entire tooling from moving on the deck.

[0037] Specifically, for example, when hoisting a 450T load, a weight (2.2T) can be connected to the steel pipe shaft 3 (φ140mm) via a steel cable. This increases the weight of the wire rope drum and roller frame, thereby increasing the friction with the deck and preventing the following dangerous situations:

[0038] (1) The traction force of the wire rope pulls the drum away from the roller frame. This is because the torque generated by the horizontal traction force on the drum on the support point of the roller frame is greater than the anti-overturning torque generated by the drum's own weight on the support point. Therefore, increasing the weight of the drum can increase the anti-overturning torque, thus avoiding the dangerous situation where the traction force pulls the drum away from the roller frame.

[0039] (2) The traction force of the wire rope pulls the roller frame at the bottom of the drum, causing the entire rope winding device to shift horizontally on the ground. This is because the horizontal traction force on the drum is greater than the friction between the roller frame and the ground. Therefore, increasing the weight of the rope winding device can increase the friction between the roller frame and the ground, thus avoiding the dangerous situation where the traction force pulls the roller frame.

[0040] When using the above method to wind up the rope, ensure that the steel cable pulls the weights a short distance off the ground. It should be noted that, based on theoretical calculations, the maximum traction force for winding the steel cable is initially estimated to be 1 ton. Therefore, the frictional force required to overcome this traction force and pull the roller frame should be greater than 1 ton. Considering the coefficient of friction between the roller frame and the ground is 0.2, the total weight of the winding device should be greater than 5 tons. Therefore, consider suspending a 2.2-ton weight at each end of the drum.

[0041] Example 2:

[0042] A rope-laying mechanism 9 is provided between the two sets of roller frames, such as... Figure 2-5 As shown, the rope arrangement structure is used to neatly wind and arrange the wire rope on the wire rope drum.

[0043] The rope winding mechanism 9 includes a guide frame structure 11 that reciprocates between the two longitudinal beams to guide the wire rope. When the guide frame structure 11 reciprocates between the two longitudinal beams, it can apply a radial driving force to the wound wire rope, thereby regularly winding the wire rope at the winding position of the wire rope drum 1. In this embodiment, since it is necessary to adapt to wire rope drums 1 of different specifications with different axial lengths, it is necessary to change the travel of the guide frame structure 11 according to the actual axial length of the wire rope drum 1. Specifically, the movement of the guide frame structure 11 is controlled by the chain transmission mechanism 12, and the travel of the guide frame structure 11 driven by the chain transmission mechanism 12 can be automatically adapted to the change of the distance between the two longitudinal beams.

[0044] Specifically, such as Figure 2 , 3 As shown, the rope-laying mechanism 9 includes a first crossbeam 13 fixedly disposed on the side of the first longitudinal beam 5 and a second crossbeam 14 fixedly disposed on the side of the second longitudinal beam 6; the chain transmission mechanism 12 includes guide sprockets 15 rotatably connected to both ends of the first crossbeam 13, return sprockets 16 rotatably connected to both ends of the second crossbeam 14, and a transmission chain 17, which is wound around the guide sprockets 15 and the return sprockets 16. The first crossbeam 13 and the second crossbeam 14 are parallel to each other and close to each other, and the first crossbeam 13 is slidably connected through the second longitudinal beam 6. The length of the first crossbeam 13 is relatively long, and the length of the first crossbeam 13 is within the adjustable range of the two roller frames 2. Figure 5 The left side represents the maximum separation distance between the two roller frames 2, and the right side represents the minimum distance between the two roller frames 2. The two roller frames 2 can stop at any position between the maximum and minimum distances, allowing the guide frame structure 11 to achieve the corresponding stroke length. Specifically, the transmission chain 17 bypasses the guide sprocket 15 at the end of the first crossbeam 13 away from the first longitudinal beam 5, and then... Figure 4As shown, the drive chain 17, which passes through two reversing sprockets 16 in an S-shape in the second crossbeam 14 and the guide sprocket 15 in the first crossbeam 13, forms the drive chain 18 that drives the guide frame structure 11 to reciprocate. It can be understood that when the distance between the two longitudinal beams changes, the length of the drive chain 18 changes with the movement of the reversing sprockets 16, thereby changing the stroke of the guide frame structure 11. In actual use, a reversible drive motor can be installed on one of the guide sprockets 15 in the first longitudinal beam 5. This drive motor can drive the drive chain 17 to move in both directions, thus driving the guide frame structure 11 to reciprocate between the two longitudinal beams. It can be understood that limit switches 40 are installed inside the two longitudinal beams to control the forward and reverse rotation of the drive motor. This allows the guide frame structure 11 to move to one side of the longitudinal beam, touch the limit switch 40, and then move in the opposite direction. This repeated motion completes the variable stroke guiding and winding function of the wire rope.

[0045] Furthermore, such as Figure 3 As shown, the guide frame structure 11 also includes a guide rod 19 fixedly connected to the side of the first longitudinal beam 5. The guide rod 19 is parallel to the first cross beam 13 and passes through the second longitudinal beam 6 and is slidably connected. The guide rod 19 is used to guide the sliding of the guide frame structure 11. In actual use, the number of guide rods 19 can be increased as needed. It also includes a moving platform 20, which is the base part at the bottom of the guide frame structure 11 for sliding connection. The moving platform 20 is slidably sleeved on the guide rod 19. The drive chain part 18 is fixedly connected to the moving platform 20, and can be driven by the transmission chain 17. The mobile platform 20 is fixedly provided with guide rings 21 on its upper surface. There are two guide rings 21, and the line connecting the two guide rings 21 is parallel to the first longitudinal beam 5. One side of the guide ring 21 is provided with a side opening 22 for the wire rope to enter. The guide ring 21 is used to guide and limit the wire rope. The side opening 22 is provided to facilitate the insertion of the wire rope into the inside of the guide ring 21 through the side opening 22. It can be understood that in order to prevent the wire rope from coming out of the side opening 22, the opening directions of the two side openings 22 can also be set in opposite directions, or a closing plate similar to the elastic opening on the lifting ring can be set on the side opening 22 to close the side opening 22 and prevent the wire rope from coming out.

[0046] Example 3:

[0047] A brushing mechanism 10 is provided between the two sets of roller frames, such as Figure 2-6 As shown, the brushing mechanism 10 is used to clean the surface of the wound wire rope. Figure 3As shown, the brushing mechanism 10 is mounted on the moving platform 20 and located between two guide rings 21. The brushing mechanism 10 includes a drive shaft 23, a mounting bracket 24, a brush ring 25, and a transmission structure. The drive shaft 23 is parallel to the guide rod 19 and one end is rotatably connected to the first longitudinal beam 5. The drive shaft 23 has a keyway 26 along its axial direction. The drive shaft 23 passes through the moving platform 20 to connect with the transmission structure. In actual use, the drive shaft 23 is driven to rotate by a power unit on the first longitudinal beam 5, which in turn drives the brush ring 25 to rotate. The mounting bracket 24 is fixedly mounted on the moving platform 20. The mounting bracket 24 has an upward-facing U-shaped opening 27. The brush ring 25 is rotatably connected inside the U-shaped opening 27. The brush ring 25 is coaxially mounted with the arc-shaped bottom wall of the U-shaped opening 27. The brush ring 25 is cylindrical and has a cylindrical ring shape. The wall has a side wall opening 28 along its axial direction for inserting the wire rope. The transmission structure is used to transmit the power of the drive shaft 23 to drive the brush ring 25 to rotate. In actual use, the surface of the wire rope is severely corroded in the high salt and high humidity conditions at the seaside, and its surface is prone to floating rust or contamination with ground particles. In order to facilitate the cleaning of surface debris or floating rust when winding the wire rope, this brushing mechanism 10 is provided. Moreover, during the winding process, the middle part of the wire rope is usually placed into the brushing mechanism 10. Therefore, the embodiment is provided with a U-shaped opening 27 and a side wall opening 28. When the side wall opening 28 is turned upward, the brushing mechanism 10 can be opened to the wire rope, making it easy to put the wire rope directly into the brush ring 25 from the middle. The inner wall of the brush ring 25 is provided with a detachable and replaceable bristle part 33. By rotating the brush ring 25, the bristle part 33 can clean the surface of the wire rope. It is understood that in this embodiment, bristles for applying protective grease to the wire rope can also be provided in the bristle part 33. As the brush ring 25 rotates, the protective grease is gradually dripped on, so that the wire rope after brushing and cleaning can be directly coated with protective grease, thereby greatly increasing the service life of the wire rope.

[0048] Specifically, such as Figure 6As shown, the transmission structure includes a sliding gear 29, a positioning gear 30, and a vertical shaft 31 rotatably connected within the mounting bracket 24. The sliding gear 29 slides on the drive shaft 23 as the guide frame structure 11 moves, and the sliding gear 29 is slidably sleeved on the drive shaft 23. Its inner wall has a protruding key that mates with the keyway 26, so the drive shaft 23 can drive the sliding gear 29 to rotate when it rotates. The vertical shaft 31 is perpendicular to the axis of the sliding gear 29, and the vertical shaft 31 has two pinions respectively located on both sides of the U-shaped opening 27. Inside, the vertical shaft 31 is used to drive the two positioning gears 30 on the same side to rotate, so that the four positioning gears 30 mesh simultaneously to drive the brush ring 25 to rotate; the sliding gear 29 synchronously drives the two vertical shafts 31 to rotate; it can be understood that the principle of the sliding gear 29 driving the vertical shaft 31 to rotate can be that the surface of the sliding gear 29 is a helical gear, and the lower end of the vertical shaft 31 is provided with a helical gear that meshes with it to achieve a 90° angle transmission; other forms that can transmit at 90° can also be used, such as the form of a worm gear or a bevel gear drive.

[0049] The positioning gear 30 is rotatably connected inside the mounting bracket 24, such as... Figure 6 As shown, the brush ring 25 is provided with an external gear 32 on its outer periphery. There are four positioning gears 30, which are respectively meshed and distributed around the external gear 32. In actual use, in order to improve the stability of the position of the brush ring 25, other supporting rolling rings can be added to fit against the outer surface of the brush ring 25. The four positioning gears 30 listed in this embodiment are used to maintain and drive the brush ring 25 to rotate. The four positioning gears 30 are synchronously driven by the vertical shafts 31 on both sides, so that the four positioning gears 30 rotate in the same direction, thereby driving the brush ring 25 to rotate.

[0050] Example 4:

[0051] To prevent the steel pipe shaft 3 from rotating with the drum, a large gap is maintained between the steel pipe shaft 3 and the shaft hole of the wire rope drum; for example... Figure 1 , 7 As shown, the steel pipe shaft 3 is provided with a rotation limiting structure that is rotatably connected to the shaft hole. The rotation limiting structure includes a positioning sleeve 34 and a bearing 35. The positioning sleeve 34 is sleeved on the steel pipe shaft 3. The positioning sleeve 34 has an annular flange 36. The bearing 35 is sleeved inside the annular flange 36. The outer ring of the bearing 35 contacts the shaft hole. The diameter of the annular flange 36 is larger than the outer diameter of the bearing 35. A positioning screw 37 is screwed into the positioning sleeve 34 radially. In use, the steel pipe shaft 3 is passed through the shaft hole, and then the lateral position of the rotation limiting structure is adjusted, such as... Figure 7As shown, the annular baffle is clamped on the outside of the shaft hole of the wire rope drum 1, and the bearing 35 is pressed against the inner wall of the shaft hole. Then, the positioning screw 37 is tightened for positioning. It can be understood that when the wire rope drum 1 rotates freely, the bearing 35 prevents the steel pipe shaft 3 from being driven to rotate, and the setting of the baffle prevents the steel pipe shaft 3 from moving axially.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
