Description

Technical Field

[0001] The invention relates to the technical field of rigging manufacturing equipment, in particular to a jointless rope loop manufacturing equipment. Background Art

[0002] Endless wire rope loop is a ring-shaped rope made by winding a continuous length of wire rope strand around a specific ring core according to the specified lay pitch. It is a branch of lifting wire rope rigging. It has the advantages of good flexibility, multiple lifting points, high strength and small lifting space requirements. It is suitable for the special requirements of large-scale lifting in various environments of marine engineering machinery and special machinery manufacturing, and is particularly suitable for limited space or extra-large lifting projects.

[0003] At present, the vast majority of domestic jointless wire rope loops are handmade, which has low efficiency and high production cost. Few companies have semi-automatic jointless wire rope loop manufacturing equipment, and most jointless rope loops still need to rely on imports. Domestic production still cannot meet the manufacturing needs of large jointless wire rope loops.

[0004] With the development of science and technology and research and development, a manufacturing device for automatically weaving jointless wire rope loops has been developed. This device consists of a driving device, a tensioning device and a strand rope winding device. The driving device is used to drive the core rope to move, and at the same time the strand rope winding device rotates 360 degrees around the core rope and pulls the strand rope out and winds it on the outside of the moving core rope. The tensioning device is used to tighten the core rope to make it taut; while the strand rope winding device of this device is rotating and winding the strand rope, it is necessary to prevent the rope loop quality problems caused by the stress of the strand rope itself, so the strand rope needs to be de-twisted and stress-relieved. The existing device is to set an I-shaped wheel on the turntable of the strand rope winding device that can rotate relative to the turntable, and can rotate and turn over while the turntable itself rotates, which is used to relieve the stress of the strand rope. The force acts on the I-shaped wheel, but the existing driving structure for the rotation of the I-shaped wheel is fixed on the turntable and needs to rotate with the turntable. However, the driving structure needs power supply, so a brush needs to be arranged on the turntable, and a matching charged slip ring is arranged under the turntable. The brush and the slip ring match and work together to power the driving structure for the rotation of the I-shaped wheel on the turntable. However, when the wire rope loop is completed and needs to be removed, an opening needs to be removed on the conductive slip ring to remove the wire rope loop. Such operation is quite troublesome and the slip ring is a charged object. It needs to be energized as a whole and wrapped around the device. When workers operate the rope loop manufacturing equipment or remove the opening of the conductive slip ring, it is very easy for workers to be electrocuted due to the conduction of the slip ring. The risk factor is quite high and the working environment risk is very large.

[0005] The outer side of the turntable of the strand winding device of the existing jointless wire rope loop manufacturing equipment is provided with a gear ring and driven by an external gear. Since the wire rope needs to pass through the center of the turntable when it is woven, the turntable and the gear ring will inevitably cause obstacles when the wire rope loop is taken out. The prior art is to open openings on the turntable and the gear ring, and also open an opening on the running track at the bottom of the turntable, and assemble and fill the opening with a filling block when in use. The filling block needs to be disassembled and assembled each time the wire rope loop is loaded and unloaded, which is very troublesome. Summary of the invention

[0006] Therefore, the technical problems to be solved by the present invention are: 1. To overcome the technical defect in the prior art that the conductive slip ring is charged, resulting in a high risk of operation; 2. To overcome the technical defect in the prior art that filling blocks need to be set on the gear ring, turntable and running track, and each time the wire rope ring is loaded and unloaded, it needs to be repeatedly disassembled and assembled, resulting in complicated operation. Therefore, a jointless rope ring manufacturing equipment with a turning over and back-twisting device is provided to solve the problem of the conductive slip ring being charged, and the openings of the gear ring, turntable and running track are always open, and there is no need to frequently disassemble and assemble the filling blocks.

Due to the fixed setting of the turning-over reduction motor, it only needs to be connected to the power supply, and there is no need to set a conductive slip ring, which naturally reduces the risk of accidental electric shock and increases the safety of the working environment;

[0024] The large turntable and the open gear ring of the present invention are both provided with openings, and due to the arrangement of the driving mechanism of the present invention, the driving active gear of the driving mechanism forms a transmission structure through the intermediate gear and the open gear ring, wherein the driving active gear transmits the rotation to the open gear ring through the intermediate gear, and since the width between the intermediate gears is greater than the width of the opening of the open gear ring, it can be well ensured that at least one intermediate gear is engaged with the open gear ring when the open gear ring and the large turntable rotate, so that when disassembling the wire rope loop, it is not necessary to install a filling block at the opening to assemble into a combined gear, and it is only necessary to keep the opening open, thereby preventing workers from frequently disassembling the filling block, increasing the speed of each disassembly and assembly, and improving work efficiency;

[0025] The present invention is provided with a rope strand pre-deformation device. After the steel wire rope strand is released from the retractable rope wheel mechanism and before it is wound on the core rope, it first passes through the rope strand pre-deformation device. The steel wire rope strand is repeatedly bent and deformed by two rollers and a pressure roller to eliminate the stress in the rope strand, so that the rope strand has a pre-deformation and stress relief operation before it is wound on the core rope, so that the rope strand can be better and more closely wound on the outside of the core rope, thereby improving the non-loosening performance and product quality of the jointless rope loop. At the same time, the distance between the first roller frame and the roller can be adjusted by the first screw to adapt to the lay length of different steel wire rope loops, and the downward pressure of the second roller frame and the pressure roller can be adjusted by the second screw to adapt to the pre-deformation work of products of different sizes, and the applicability is relatively wide.

[0026] The present invention is provided with a meter counter, and the meter counter is provided with a wireless transmitting device and is powered by a battery. The traction reduction motor of the active traction wheel mechanism of the core rope driving device is provided with an encoder to read the rotation speed of the active traction wheel. The meter counter can read the rope strand withdrawal speed in real time, and send it to the PLC through the wireless transmitting device for comparison with the core rope traction speed. The rope strand withdrawal speed and the rotation speed of the active traction wheel should be in a fixed ratio. If the ratio changes, it proves that the core rope slips and the lay pitch changes. At this time, the traction reduction motor will actively change the speed adjustment through the encoder and PLC control to change the slip state, ensure the speed ratio is consistent, and ensure the lay pitch is accurate. If the speed ratio changes too much, it proves that the slip is more serious, then an alarm will be issued and the machine will stop. The arrangement of this structure increases the accuracy of the lay pitch of the device, improves the product quality, and prevents the slip between the core rope and the traction wheel from causing a decrease in product quality.

[0059] When the present invention is used, the core rope is firstly put on the core rope driving device, and the core rope is passed through the opening 55 of the outer ring track 56 and the inner ring track 57, and passes through the opening 55 of the open gear ring 54 and the opening 55 of the large turntable 4, and passes through the opening 55 of the open central axis 3 so that the core rope is located at the opening 55 in the center of the open central axis 3, and then the core rope is placed on and bypassed on the sliding driven traction wheel 15, the driven traction wheel 16 and the active traction wheel 18 in sequence, and the right end of the core rope bypasses the tensioning wheel 26 of the hydraulic tensioning device 1, and the positions of the first sliding trolley 21 and the second sliding trolley 22 on the tensioning track 20 are determined according to the length of the wire rope loop, and the first sliding trolley 21 and the second sliding trolley 22 are slid along the tensioning track 20 to the specified position, that is, The circular hole 28 on the fixed beam 25 is connected to the fixed hole of the second sliding trolley 22 through a pin and fixes their positions. Then, the hydraulic cylinder 24 is controlled by the external PLC electrical control system to tighten the first sliding trolley 21 so that the right end of the core rope is tightened and the tension is constant through the tension wheel 26, that is, the installation of the core rope is completed. Then, the steel wire rope strand is wound onto the I-shaped wheel 43, and the pin 49 is inserted into the pin hole 48 of the I-shaped wheel 43 and the second winding gear 47, so that the second winding gear and the I-shaped wheel 43 operate synchronously. The winding reduction motor is started to drive the first winding gear 46 to rotate, and the first winding gear 46 drives the second winding gear 47 to rotate. The second winding gear 47 drives the I-shaped wheel 43 to rotate through the pin 49 to wind the rope strand onto the I-shaped wheel 43. The winding reduction motor is on the spool 43, and then the power is turned off and the plug 49 is unplugged. The winding reduction motor is only powered on when winding, and is not in a powered state when the large turntable 4 rotates to wind the rope strands, so there is no need to worry about the power supply problem. Then the steel wire rope strands on the spool 43 are passed around the meter 29, through the rope strand pre-deformation device 30 and wound around the core rope, the core rope driving device and the strand rope winding device are started, and the traction reduction motor 19 drives the active traction wheel 18 to move through the transmission chain, and drives the core rope to reciprocate between the sliding driven traction wheel 15, the driven traction wheel 16 and the tensioning wheel 26, while its left end passes through the open central axis 3 and the center of the large turntable 4, and the driving mechanism drives the large turntable 4 to rotate. Specifically, the driving reduction motor The machine 51 drives the two intermediate gears 53 to rotate, the two intermediate gears 53 drive the open gear ring 54 to rotate, and the open gear ring 54 drives the large turntable 4 to rotate. Since the spacing between the two intermediate gears 53 is greater than the width of the opening 55, there can always be an intermediate gear 53 engaged with the open gear ring 54, so that normal transmission can be maintained. The large turntable 4 drives the small turntable 5 to rotate, wherein the wheel 58 at the bottom of the large turntable 4 rolls along the inner ring track 57, and the wheel 58 at the bottom of the small turntable 5 rolls along the outer ring track 56. The small turntable 5 drives the rope retracting and releasing I-shaped wheel mechanism 6 to rotate along the center of the core rope and fixes the strand rope on the I-shaped wheel 43 to the core rope through the meter 29 and the rope strand pre-deformation device 30, thereby completing the automatic weaving of the wire rope loop;

[0060] The inner ring track 57 and the outer ring track 56 are used to support the large turntable 4, the small turntable 5 and the rope retracting and releasing I-shaped wheel mechanism 6 during rotation;

[0061] After the preparation is completed, since a sliding mechanism is provided below the sliding driven traction wheel 15, the sliding driven traction wheel 15 is moved inward by a distance of a rope loop diameter. This is done to facilitate the removal of the rope loop from the device. Since the core rope also needs to pass through the sun gear 10 when disassembling and assembling it, a break is provided on the sun gear 10 and a assembleable and detachable filling block is provided at the break. First, remove the filling block on the sun gear 10, and then take out the rope loop located in the open central axis 3 from the opening 55 of the large turntable 4, the open gear ring 54, the inner ring track 57 and the outer ring track 56. The opening 55 is normally open and does not need to be filled.

[0062] The filling block of the sun gear only requires a few steps for disassembly and assembly, and the time saved is almost negligible compared to the open gear ring 54, the large turntable 4, the inner ring track 57 and the opening 55 of the outer ring track 56, so in fact, the overall time for disassembly and assembly of the rope loop is saved.

[0063] When passing through the rope strand pre-deformation device 30, the rope strand passes through two rollers 34, and the rope strand is pressed inwardly by a pressure roller 35 in the center. The specific operation method is to first screw the first screw 37 so that it drives the two first roller frames 32 to move along the slide 31 and adjust the spacing between the two rollers 34 to adapt to the lay pitch of the rope loop, and then screw the second screw 38 so that the second roller frame 33 slides inwardly along the support plate 40 and adjusts the pressing amount of the pressure roller 35 to press the rope strand. The two rollers 34 and the pressure roller 35 are used to repeatedly bend and deform the steel wire rope strand to eliminate the stress in the rope strand and improve the non-loosening performance of the rope loop;

[0064] The length of the strand rope drawn out and the distance of the core rope traction should be in a fixed ratio, so as to ensure the accuracy of the lay pitch of the strand rope winding. The meter 29 of the present invention is used to read the length of the strand rope drawn out, and a battery is provided on the meter 29 of the present invention, so it does not need to be powered when rotating. At the same time, the encoder of the traction reduction motor 19 can read the rotation speed of the active traction wheel 18 and send it to the external PLC electrical control system. The meter 29 sends the reading to the external PLC electrical control system through a wireless transmission device, and calculates a fixed ratio of the two data and compares them with the required ratio. If the fixed ratio changes with the required ratio, it proves that the core rope is slipping. The external PLC electrical control system adjusts the rotation speed of the traction reduction motor 19 to adjust the rotation speed of the active traction wheel 18 for compensation. If the fixed ratio is very different from the set ratio, an alarm is issued to shut down.

[0065] The tension of the hydraulic cylinder 24 of the present invention can be set in the external PLC electrical control system, and the upper and lower deviations can be set to adapt to the production of products with different diameters. When the core rope rotates in the traction wheel, if the upper and lower deviations are exceeded, the hydraulic cylinder 24 will automatically adjust the tension so that the tension of the tension wheel 26 on the core rope remains unchanged, preventing the tension from being too small and causing slippage, or the tension from being too large and causing the rope loop to be elongated.

[0066] The turning and detwisting device of the present invention can also drive the rope-retracting I-wheel mechanism 6 to rotate while the large turntable 4 revolves, which is also called turning over. Its purpose is to eliminate the stress of the strands of rope wound on the core rope. Turning over is divided into positive turning over, negative turning over and zero turning over. Positive turning over means that the rotation speed of the large turntable 4 is greater than the rotation speed of the rope-retracting I-wheel mechanism 6, negative turning over means that the rotation speed of the large turntable 4 is less than the rotation speed of the rope-retracting I-wheel mechanism 6, and zero turning over means that the rotation speed of the large turntable 4 is equal to the rotation speed of the rope-retracting I-wheel mechanism 6. In these three cases, the rotation direction of the large turntable 4 is opposite to the rotation direction of the rope-retracting I-wheel mechanism 6, and when it is in zero turning over, the rope-retracting I-wheel mechanism 6 has no rotation angle relative to the ground. The specific turning ratio is determined by the turning reduction motor 8 and the external PLC electrical The control system controls, specifically, during positive turning, the turning reduction motor 8 rotates forward to drive the turning active gear 9 to rotate, that is, it is transmitted to the outer ring gear 14 of the slewing bearing 7 through the sun gear 10, the first linkage gear 11 and the second linkage gear 12, and drives the rope retracting and releasing I-wheel mechanism 6 to rotate; during negative turning, the turning reduction motor 8 rotates reversely to drive the turning active gear 9 to rotate, that is, it is transmitted to the outer ring gear 14 of the slewing bearing 7 through the sun gear 10, the first linkage gear 11 and the second linkage gear 12, and drives the rope retracting and releasing I-wheel mechanism 6 to rotate; during zero turning, the turning reduction motor 8 is in a braking state and does not operate. This device does not need to set brushes and conductive slip rings at the bottom of the large turntable 4 to prevent leakage, and only needs to supply power to the fixed turning reduction motor 8.
