Description

Technical Field

[0001] The invention relates to the technical field of replacing steel wire ropes of a crane, and in particular to a device for replacing steel wire ropes in a crane rope reel. Background Art

[0002] In actual work, hydraulic cranes often have a high failure rate due to lack of proper maintenance, improper operation, poor working environment and disrepair. In the maintenance of existing medium and large cranes, cranes and stern doors in ro-ro ships, there is often an operation to replace new wire ropes. The most critical part of the operation is to control the speed of the wire and oil the new wire rope when installing the wire. In the past, the operation usually required a dedicated person to control the rotation speed of the wire drum, and multiple people were required to apply butter to the new wire rope, which was both labor-intensive and inefficient.

[0003] Chinese patent CN210193078U discloses an automatic oiling wire rope replacement device, including a base, on which are provided a mounting frame for placing the wire rope, an oil storage cylinder for storing oil, and a working cylinder for oiling the wire rope. The wire rope on the mounting frame passes through the working cylinder and the oil scraper groove and is connected to the wire rope to be replaced.

[0004] Although the above scheme can refuel the wire rope before installing the wire rope, the old wire rope needs to be removed before replacing the wire rope. When removing the crane wire rope, 7-8 people are required to pull it at different parts, which is time-consuming and laborious. During the process, according to the needs of construction, 1 to 2 people need to frequently enter the leeward position of the falling trend of the wire rope, which poses a greater risk of being hit by objects. In addition, due to the needs of use, the diameters of the wire ropes used on the crane are not consistent. Therefore, the existing single drum cannot collect multiple wire ropes on the crane in an orderly manner, and different Wire ropes of different diameters have different requirements for curling radius, that is, the thicker the wire rope, the larger the corresponding curling radius. If the curling radius is smaller than the required curling radius, the wire rope will be damaged during the winding process. The diameter of the existing reel for receiving the wire rope is fixed, and the reel cannot be replaced quickly. At the same time, the existing reel cannot guide the wire rope to be wound around the reel in an orderly manner, and there is a lack of safety devices around the reel. If twisting occurs during the winding process of the wire rope, it will cause the wire to rebound, which in turn leads to injury accidents. Summary of the invention

[0005] In view of the above problems, a device for replacing the wire rope in a crane rope reel is provided. When in use, the staff selects a corresponding reel according to the diameter of the wire rope to be reeled, first removes the limit plate from the end of the base, and then sleeves the reel on the drive shaft in the base. When all the reels are placed in the base, the limit plate is fixed on the end of the base, and then the wire rope is passed through the guide hole on the guide rod and wound around the reel. Then the first rotary drive drives the drive shaft to rotate, and the reel drives the wire rope to be reeled, and the winding guide device is arranged along the base. The wound wire rope is guided in the length direction, and the same-layer guide device guides the wire rope to be fully wound before winding the next layer, thereby avoiding the situation where the wire rope wound on the drum is wound in multiple layers. The same-layer guide device is used to assist the winding guide device to evenly wind the wire rope on the drum, so that the wire rope can be collected reasonably and orderly, avoiding damage to the wire rope due to disorder when winding, and by setting up multiple drums, multiple wire ropes can be placed in a classified manner, thereby realizing orderly management of multiple wire ropes, making the drum detachable, and improving the speed of replacing the drum.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1 , Figure 3 and Figure 5 : A device for replacing the wire rope in a crane hoisting machine, comprising a base 1, a first driving device 5 and a control console; the device also includes a replacement unit 3 and a guide unit 4; the replacement unit 3 is arranged on the base 1, and a drum 2 is arranged on the base 1, and the drum 2 is used to reel in the wire rope 6. The staff replaces the drum 2 on the base 1 through the replacement unit 3; the guide unit 4 is arranged on one side of the base 1 along the length direction of the base 1, and the guide unit 4 is used to guide the wire rope 6 to be evenly wound around the drum 2.

[0032] The first driving device 5 is arranged on the base 1 along the length direction of the base 1, and the control console is arranged on one side of the base 1. When in use, the diameter of the wire rope 6 to be wound and the diameter of the drum 2 are input into the control console, and the control console operates according to the above numerical control guide unit 4. Before operation, if the diameter of the drum 2 on the base 1 does not meet the diameter requirement of the wire rope 6 to be wound, it is necessary to replace the drum 2 on the base 1 through the replacement unit 3. A replacement port is arranged at the end of the base 1. Since there are multiple drums 2 on the base 1, when replacing, the drum 2 on the base 1 needs to be replaced. The reels 2 that meet the requirements are removed one by one along the length direction of the base 1 from the replacement port, and the reels 2 that meet the requirements are pushed into the base 1 from the replacement port one by one, so that the installation of the reel 2 is completed. Then the wire rope 6 that needs to be wound passes through the guide unit 4 and is wound on the reel 2. Then the first drive device 5 is started, and the first drive device 5 drives the reel 2 to rotate, so that the wire rope 6 is wound on the reel 2. By arranging multiple reels 2, multiple wire ropes 6 can be placed in categories, thereby realizing orderly management of multiple wire ropes 6, making the reel 2 detachable, and improving the speed of replacing the reel 2.

[0033] Reference Figure 5 : The replacement unit 3 also includes a receiving seat 31 and a limiting assembly 32; the receiving seat 31 is arranged at the bottom of the base 1, and when the reel 2 is replaced, the reel 2 can slide in the base 1 along the length direction of the base 1, and the receiving seat 31 receives the sliding reel 2; the base 1 is provided with a replacement opening at one end in its own length direction, and the limiting assembly 32 is provided with a replacement opening, and the reel 2 is put in or taken out from the replacement opening.

[0034] The first driving device 5 includes a driving shaft 52, and the reel 2 placed in the base 1 is sleeved on the driving shaft 52. Since the reel 2 after being wound with the wire rope 6 is very heavy, if the bottom of the reel 2 is not provided with a receiving seat 31 to receive the reel 2, the reel 2 after being wound with the wire rope 6 will not be able to be taken out from the base 1. This is because the heavier reel 2 will bend the driving shaft 52, causing damage to the driving shaft 52. The limiting component 32 arranged at the replacement port can prevent the reel 2 located in the base 1 from slipping out of the replacement port.

[0035] Reference Figure 6The limiting assembly 32 includes a limiting disk 321, a rotating ring 322, a first clamping block 323 and a second clamping block 324; the replacement port is a circular structure, and the rotating ring 322 is rotatably arranged at the end of the base 1 along the axis of the replacement port; there are multiple first clamping blocks 323, and the first clamping blocks 323 are evenly fixed around the axis of the rotating ring 322 at the end of the rotating ring 322 away from the base 1; the second clamping block 324 corresponds to the first clamping block 323 one by one, and the second clamping block 324 is evenly fixed around the axis of the reel 2 arranged in the base 1; the limiting disk 321 is arranged at the end of the rotating ring 322 away from the base 1 along the axis of the replacement port, and the limiting disk 321 is provided with a first clamping groove and a second clamping groove, the first clamping groove is clamped with the first clamping block 323, and the second clamping block 324 is clamped with the second clamping groove.

[0036] A fixing hole is provided on the limit plate 321. When in use, it is assumed that the limit plate 321 is not provided on the base 1, and at this time there is no reel 2 on the base 1. First, the reel 2 needs to be pushed into the base 1 along the axis of the replacement port. When the reel 2 is completely pushed into the base 1, the end face of the reel 2 close to the replacement port is coplanar with the end face of the base 1. Then, the rotating ring 322 is rotated so that the first clamping block 323 provided on the mountain of the rotating ring 322 corresponds to the second clamping block 324 provided on the end of the reel 2. In the present invention, for ease of understanding, the first clamping block 323 is referred to as Block 323 and the second clamping block 324 both adopt a long strip structure. The length direction of the first clamping block 323 is parallel to the radial direction of the rotating ring 322, and the second clamping block 324 is parallel to the radial direction of the reel 2. When the first clamping block 323 and the second clamping block 324 are aligned, the length extension direction of the first clamping block 323 coincides with the length extension direction of the second clamping block 324. Then, the limit plate 321 is placed at the end of the base 1, so that the first clamping groove and the second clamping groove on the limit plate 321 are respectively clamped and matched with the first clamping block 323 and the second clamping block 324.

[0037] Reference Figure 3 : Multiple reels 2 are arranged inside the base 1 along the length direction of the base 1.

[0038] Since there are multiple steel wire ropes 6 in the crane, the traditional winding method only uses one reel 2 for winding the steel wires, so that the multiple steel wire ropes 6 are entangled together, causing the steel wire ropes 6 to be disordered after being wound. After multiple reels 2 are provided, different steel wire ropes 6 can be respectively wound in different reeling drums 2, thereby ensuring the orderly collection of different steel wire ropes 6.

[0039] Reference Figure 5 and Fig. 9: The first driving device 5 includes a first rotating driver 51 and a driving shaft 52; the first rotating driver 51 is arranged at the end of the base 1 along the length direction of the base 1; the driving shaft 52 is fixedly arranged on the output end of the first rotating driver 51 along the length direction of the base 1, the driving shaft 52 is located in the base 1, the cross-section of the driving shaft 52 is a non-circular structure, and a driving groove is opened on the reel 2 along the axis of the reel 2, and the driving groove is slidably matched with the driving shaft 52.

[0040] When the reel 2 is placed into the base 1 from the replacement port on the base 1, it is necessary to align the driving groove on the reel 2 with the driving shaft 52 arranged on the output end of the first rotation driver 51, and then insert the reel 2 onto the driving shaft 52. The first rotation driver 51 is preferably a servo motor. When the first rotation driver 51 is started, the driving shaft 52 can drive the reel 2 located in the base 1 to rotate. If the cross-section of the driving shaft 52 is circular, the driving shaft 52 cannot drive the reel 2 to rotate after the rotation of the driving shaft 52, and then the wire rope 6 cannot be reeled by the rotation of the reel 2. It is worth noting that when the reel 2 is placed in the base 1, the reel 2 is received and guided by the receiving seat 31. When the wire rope 6 is wound around the reel 2, the weight of the reel 2 will be very large. However, since the receiving seat 31 receives the reel 2, the weight of the reel 2 can be avoided from acting on the driving shaft 52, thereby ensuring that the driving shaft 52 is not bent by the reel 2.

[0041] Reference Figure 1 and Figure 7 : The guide unit 4 includes a winding guide device 41 and a same-layer guide device 42; the winding guide device 41 is slidably set on one side of the base 1 along the length direction of the base 1, and the wire rope 6 passes through the guide end of the winding guide device 41 and is wound on the drum 2; the same-layer guide device 42 is set on one side of the drum 2 along the radial direction of the drum 2 located in the base 1, and the same-layer guide device 42 presses the wire rope 6 wound on the drum 2 along the radial direction of the drum 2.

[0042] Reference Figure 1-Figure 4 and Figure 7 : The reel 2 arranged in the base 1 corresponds to the winding guide device 41, and the winding guide device 41 includes a second driving device 411 and a guide rod 412; the second driving device 411 is arranged on the base 1; the guide rod 412 is slidably arranged on one side of the base 1 along the length direction of the base 1, one end of the guide rod 412 is connected to the second driving device 411, and the second driving device 411 drives the guide rod 412 to move, and a guide hole is penetrated at one end of the guide rod 412 away from the second driving device 411. For every rotation of the reel 2, the guide rod 412 moves along the length direction of the base 1 by a distance equal to the diameter of the wire rope 6 wound on the reel 2.

[0043] The guide end of the guide device refers to the end of the guide rod 412 provided with a guide hole, the wire rope 6 passes through the guide hole and is wound on the drum 2, the second driving device 411 includes a second rotary driver 4111, a first gear 4112, a second gear 4113, a sliding frame 4114, a sliding block 4115 and a threaded rod 4116, the sliding frame 4114 is fixedly arranged on the base 1 along the length direction of the base 1, and the number of sliding frames 4114 corresponds to the number of drums 2. If multiple drums 2 are provided, the sliding frames 4114 are arranged along the base 1. The threaded rod 4116 is evenly arranged in the length direction of the sliding frame 4114, and the sliding block 4115 is slidably arranged on the sliding frame 4114 along the length direction of the sliding frame 4114. The threaded rod 4116 penetrates the sliding block 4115 and is threadedly matched with the sliding block 4115. The end of the guide rod 412 without a guide hole is fixedly connected to the sliding block 4115. When the sliding block 4115 slides, it drives the guide rod 412 to move synchronously. The first gear 4112 is fixed along the axis of the threaded rod 4116. The second rotary drive 4111 is arranged at the end of the threaded rod 4116, the second rotary drive 4111 is arranged on the upper part of the sliding frame 4114, the second gear 4113 is fixedly arranged on the output end of the second rotary drive 4111, the second gear 4113 is meshed with the first gear 4112, and the second rotary drive 4111 is preferably a servo motor. When the second rotary drive 4111 is started, the second rotary drive 4111 drives the first gear 4112 to rotate through the second gear 4113, so that the first gear 4112 drives the threaded rod 4116 to rotate. In this way, the sliding block 4115 located on the sliding frame 4114 drives the guide rod 412 to move synchronously. Every time the first driving device 5 drives the reel 2 to rotate one circle, the guide rod 412 moves along the length direction of the base 1 by a distance equal to the diameter of the wire rope 6 wound on the reel 2. In this way, the wire rope 6 can be evenly wound on the reel 2. The driving amount of the second driving device 411 is the same as the diameter of the wire rope 6 input by the control console. The driving amount of the second driving device 411 is the distance moved by the guide rod 412 during the period of one rotation of the reel 2.

[0044] Reference Fig. 9 and Fig.10: The same-layer guide device 42 includes a pressing plate 421, a pressing device 422 and a placing plate 423; the pressing plate 421 is an arc-shaped structure, and the pressing plate 421 is slidably arranged on one side of the reel 2 along the radial direction of the reel 2 located in the base 1, and the pressing plate 421 presses the wire rope 6 wound on the reel 2; the placing plate 423 is fixedly arranged on the base 1 along the length direction of the base 1, and the pressing plate 421 is located on the side of the placing plate 423 close to the base 1; the pressing device 422 is arranged at the end of the pressing plate 421 close to the placing plate 423 along the moving direction of the pressing plate 421, and the pressing device 422 penetrates the placing plate 423, and the pressing device 422 provides pressing force for the pressing plate 421.

[0045] The pressing device 422 includes a pressing rod 4221, a limiting plate 4222 and a spring 4223. The pressing rod 4221 is fixedly arranged on one end of the pressing plate 421 close to the placing plate 423 along the moving direction of the pressing plate 421. The pressing rod 4221 is penetrated and arranged on the placing plate 423 along the moving direction of the pressing plate 421 and slidably cooperates with the placing plate 423. The limiting plate 4222 is arranged on the side of the placing plate 423 away from the pressing plate 421. There is a gap between the limiting plate 4222 and the placing plate 423. The spring 4223 is arranged in the gap along the axis of the pressing rod 4221. The two ends are fixedly connected to the limit plate 4222 and the placement plate 423 respectively. When the drum 2 reels the wire rope 6, the continuously wound wire rope 6 will cause the number of layers of the wire rope 6 on the drum 2 to gradually increase, so that the pressing plate 421 in contact with the wire rope 6 on the drum 2 is pushed by the continuously stacked layers of steel wires, so that the gap distance between the placement plate 423 and the limit plate 4222 is continuously increased, and the spring 4223 located on the gap is also continuously stretched. The stretched spring 4223 provides pressing force on the pressing plate 421, so that the wound wire rope 6 cannot overcome the pressing force of the pressing plate 421 and is wound disorderly.

[0046] Reference Figure 1 and Figure 3 The guide unit 4 further comprises a protection plate 43, which is an arc-shaped structure and is fixedly arranged on the periphery of the base 1 along the axis of the replacement port.

[0047] When the steel wire rope 6 rebounds, the protection plate 43 can prevent the steel wire rope 6 located in the drum 2 from popping out, thereby protecting the personal safety of surrounding workers.

[0048] Reference Figure 8-Figure 10: The same-layer guide device 42 also includes a protection device 424, which is arranged on the pressing plate 421. The protection device 424 is provided with a preset movement value. The protection device 424 includes a monitoring unit and an execution unit. The protection device 424 monitors the movement speed of the pressing plate 421 in real time through the monitoring unit. When the monitored real-time movement value is greater than the preset movement value, the protection device 424 locks the pressing plate 421 through the execution unit.

[0049] The monitoring part of the protection device 424 includes a follower rod 4241, a third gear 4242 and a speed sensor 4243. The follower rod 4241 is fixedly arranged at one end of the pressing plate 421 close to the placing plate 423 along the moving direction of the pressing plate 421. The follower rod 4241 penetrates the placing plate 423 along the moving direction of the pressing plate 421 and slides with the placing plate 423. The bottom of the follower rod 4241 is evenly provided with a plurality of meshing teeth along the length direction of the follower rod 4241. The third gear 4242 is rotatably arranged at the bottom of the follower rod 4241. The third gear 4242 is meshed with the meshing teeth at the bottom of the follower rod 4241. The speed sensor 4243 is arranged at the third gear 4242. At the end of the third gear 4242, when the wire rope 6 rebounds due to the torsion in the process of being wound on the reel 2, the rebounding wire rope 6 will quickly push the pressing plate 421, so that the pressing plate 421 drives the follower rod 4241 to move quickly. At this time, the third gear 4242 meshing with the follower rod 4241 also rotates synchronously, and the speed sensor 4243 arranged at the end of the third gear 4242 can monitor the increase in the speed of the third gear 4242. The speed sensor 4243 is preset with a maximum speed value, and the maximum speed is proportional to the preset movement value. The real-time speed value monitored by the speed sensor 4243 is proportional to the real-time movement speed of the pressing plate 421. The speed value is also directly proportional to the speed value, so when the real-time speed of the third gear 4242 monitored by the speed sensor 4243 is greater than the maximum speed value preset by the speed sensor 4243, the actuator of the protection device 424 is activated, and the actuator of the protection device 424 includes a turntable 4244, a pop-up block 4245 and a pump body 4246. The turntable 4244 is fixedly arranged at the end of the third gear 4242 along the axis of the third gear 4242, and pop-up grooves are evenly opened on the circumferential wall of the turntable 4244. The length direction of the pop-up groove is parallel to the radial direction of the turntable 4244. The pop-up block 4245 is slidably arranged in the pop-up groove along the extension direction of the pop-up groove. The pump body 4246 is arranged on the turntable At the end of the disk 4244, the pump body 4246 drives the ejection block 4245 in the ejection groove to eject. After the ejection block 4245 in the turntable 4244 is ejected, the rotating turntable 4244 drives the ejection block 4245 to be stuck with the placement plate 423, so that the follower rod 4241 can no longer move. Since the pressing plate 421 is always in contact with the wire rope 6 wound on the reel 2, when the wire rope 6 rebounds, the pressing plate 421 in contact with the wire rope 6 can monitor the changes of the wire rope 6 as quickly as possible, thereby shortening the travel of the wire rope 6 after the rebound, thereby avoiding the rebound of the wire rope 6 from hitting the protective plate 43, causing serious damage to the protective plate 43.
