Description

Technical Field

[0001] The invention relates to the field of manufacturing equipment for steel wire rope slings, in particular to mechanized production equipment for heavy-duty jointless steel wire rope loops. Background Art

[0002] In the production practice of marine engineering, there is a very important product: heavy-duty wire rope sling-jointless rope loop (hereinafter referred to as: heavy-duty jointless wire rope loop, or jointless wire rope loop, or rope loop), which highlights its economic and strategic value. The jointless rope loop is a kind of circular rigging made of a whole wire rope and braided and knotted by a special process. It plays an irreplaceable and important role in the lifting operation requirements such as narrow lifting space, strict lifting mechanical characteristics, and super-large workpieces. From the concept of topological mathematics, the jointless rope loop is a knotted ring, and the cross-section of the ring body presents the structural characteristics of 1 rope core + 6 rope strands. The rope core and the rope strand are the same wire rope knotted and woven, and the connecting line of the center point of the rope bundle cross section in the free state must be in the same plane. The remarkable feature of the jointless rope loop is that it is suitable for the special requirements of large-scale lifting in special harsh environments, especially for limited space or super-large lifting operations. It has a wide range of applications in marine engineering and petroleum engineering such as docks, large ships and vessels, drilling oil platforms, etc. It is difficult to replace by other means, and it is a consumable and must be eliminated and replaced after a certain number of uses and lifespan.

[0003] Some product parameters require the cross-sectional diameter of the rope loop to be close to 1 meter, the length to be hundreds of meters, and the single weight to be hundreds of tons. Light rope loops can still be woven manually, but heavy rope loops are difficult to be woven independently by humans. For products with slightly larger quantities, the industry currently basically cooperates with lifting cranes and relies on physical labor to pull back and forth, which is inefficient, slow, and cannot guarantee quality. The tightness is inconsistent, the shape is twisted and scattered, and it is impossible to weave qualified special-shaped and oversized rope loop products.

[0004] Some manufacturers at home and abroad have conducted exploratory research and development of production equipment. Currently, only experimental equipment can carry out trial production of small and micro rope loop products with slender cross-sectional diameters. Medium-sized products have not yet been involved, and heavy-duty products are even more blank. The main shortcomings of rope loop product production equipment in the prior art are: a set of traction guide wheels on the equipment will open the rope loop to be wound, and the guide wheel rim is processed into a groove to accommodate the rope bundle of the embedded rope loop. According to industry standards and design specifications, the diameter of a highly flexible wire rope guide wheel shall not be less than 18 times the cross-sectional diameter of the wire rope, and the diameter of an ordinary wire rope guide wheel shall not be less than 20 to 25 times. For rope loop products with a cross-section showing a multi-strand twisted feature of 1 rope core + 6 rope strands, the guide wheel diameter should take a larger value. When producing rope loop products with larger cross-sectional diameters, the guide wheel diameter will be a very large size. For example, when producing rope loop products with a cross-sectional diameter of 600mm, the diameter of a single guide wheel must not be less than φ12 meters. This is unattainable for mechanical equipment, and the groove type of the guide wheel rim must also be changed according to the cross-sectional diameter of the rope bundle. Too large a groove type will cause the rope bundle to slip, and too small a groove type will cause it to get stuck.

[0005] Another shortcoming is that the layout of the traction wheel of the rope loop products with different lengths needs to be adjusted accordingly to adapt, which is not flexible enough. Under the condition of ensuring the diameter of the rope bundle cross section, the space must accommodate this set of traction wheels, so it is impossible to make products with a relatively small loop length of the wire rope loop. The wire rope loop with a smaller loop length is exactly the one with the largest engineering demand. In addition, due to the limitation of the traction wheel, the rope loop product will bend in both directions during the production process. In fact, in the production and storage and transportation of the wire rope loop, the reverse bending deformation is very harmful. The length and weight of the wire rope loop are very large, so the tension force received by the traction wheel is very high. The rope loop with a cross-sectional diameter of 600mm has a span of 6 meters, a tension force of 100 tons, and a droop deflection of 300mm. Therefore, the use of the traction wheel method will inevitably lead to a large and bulky equipment structure.

[0006] In summary, it is extremely difficult to break through the mechanized equipment processing of large-section diameter wire rope loop products in the existing technology. Therefore, the mechanized wire rope loop production equipment carried out by the existing technology is basically limited to light-duty and small-diameter products. The production and manufacturing of medium-sized rope loop products still relies on manual manpower, supplemented by cranes, to reciprocate the rope strands or rope strands wound on the reel. It is even more difficult to rely on this method for heavy products. If manual weaving is used, it is extremely difficult to use such large-sized and heavy single products, and the efficiency is low and the quality cannot be guaranteed, the performance parameters are inconsistent, and the quality and parameters cannot be guaranteed.

DETAILED DESCRIPTION

[0041] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0042] like Figures 1 to 5 and Figure 7 As shown, the main rotating frame 1 is supported and connected by a tubular component with a single-side slot, connecting the disc-shaped support parts at both ends. The main rotating frame 1 has a through area 501 in the center to allow the steel rope loop rope bundle 303 to pass through. The disc-shaped support parts at both ends have two holes that are coaxial and colinear with the frame rotation axis 202, and the two holes are used to install the rear axle head 6 and the front hollow axle head 7 of the frame 3. The disc-shaped support parts at both ends of the main rotating frame 1 are fixedly connected to the outer edge part 2, and the outer edge part 2 has a notch to form a non-closed circular ring. The disc-shaped support parts at both ends of the main rotating frame 1 have slots, and the notch of the outer edge part 2, the notch of the disc-shaped support part, and the single-sided slot of the tubular component are connected in space to allow the rope bundle to be put in and taken out during the processing.

[0043] The outer edge 2 on the main rotating frame 1 contacts and is supported by a group of rollers 8. Each outer edge 2 contacts no less than 4 rollers 8, and the spacing between adjacent outer edges 2 is no less than the opening distance of the outer edge 2, so as to ensure smooth bridging transition of the opening part when the outer edge 2 rolls. The rope strand 302 to be wound on the rope bundle 303 is pre-spirally wound in the rope strand storage reel 4, and passes through the front hollow shaft head 7, merges into and is wound on the rope bundle 303. The rope strand reel is connected to the bracket 3 through the core shaft 5, and the rear shaft head 6 and the front hollow shaft head 7 of the bracket 3 are connected to the two corresponding mounting hole shaft seats of the main rotating frame 1. When the main rotating frame 1 rotates with power, the bracket 3 can rotate with power, and the rotation of the main rotating frame 1 and the bracket 3 can be independently controlled.

[0044] In this embodiment, the rotary drive device 14 of the frame 3 is a reduction motor, which is installed on the main rotary frame 1 and the power output shaft is connected to the rear axle head 6 to transmit torque.

[0045] In this embodiment, the main rotary drive device 13 of the main rotary frame 1 is installed on the frame of the supporting roller 8 and transmits the rotational torque to more than two supporting rollers 8 to ensure that the torque is transmitted normally and uninterruptedly when the notch of the outer edge 2 passes through. The supporting roller 8 is driven by contacting and rubbing the tread of the outer circle of the outer edge 2; the friction power transmission method between the supporting roller 8 and the outer edge 2 is an arc surface friction pair.

[0046] The dragging mechanism 9 drags the rope ring 10 out of the through area 501 of the main slewing frame 1, and drags the rope strands 302 that have been collected, so that the rope strands pre-wound on the rope strand storage reel 4 are passively unwound, and the rope strand storage reel 4 is passively unwound at the same time. There are dampers and brakes between the rope strand storage reel 4 and the frame 3 to adjust the tension of the rope strands.

[0047] The main rotating frame 1 can rotate along the main rotating axis 201, and the rope strand storage reel 4 rotates along the main rotating axis 201 to generate the action of winding the rope strands around the rope ring 10. When the rope strand storage reel 4 passively rotates along the main rotating axis 201, it also actively rotates along the rotating axis 202 of the frame. Under the combined action of the above two movements, the movement trajectory 205 of the rope strand storage reel 4 is as shown in Fig. 9 As shown, the strand storage reel 4 rotates along the main rotation axis 201 for winding action, and rotates along the frame rotation axis 202 for twisting action. The twisting rotation can be clockwise or counterclockwise, or zero value rotation. The twisting ratio can also be set according to the product parameters required by the customer to obtain the best product quality characteristics.

[0048] like Figure 8 As shown, it is another embodiment of the main rotating frame 1. In this embodiment, a tubular member with a groove in the middle is used for connection, and the plates on both sides are used to install the bearing seat supporting the shaft head of the bracket, and the outer edge 2 is also connected to a circular plate member independent of the main structural frame body. Since it is not limited by the installation space of the accessories of the main rotating frame 1 such as the counterweight 11, the outer edge 2 can be smaller than the diameter of the rotary sweep envelope of the main rotating frame 1 when it is working. The main rotary drive device 13 of the main rotating frame 1 is a motor reducer output shaft with a transmission pair active end installed, and the main rotating frame 1 is equipped with a transmission pair driven end, which drives the main rotating frame 1 to rotate; the transmission pair can be a gear pair, a pin gear pair, a belt, etc.

[0049] During production, the towing mechanism 9 drags the steel rope loop to travel in a circular path. During the circular movement, one end of the steel rope loop is drawn out from the exit of the through area 501 of the main slewing frame 1, and the rope bundle at the entrance of the through area 501 is passively drawn in. The horizontal curved disc is flatly laid and folded on the ground foundation 12. The motion characteristics of each particle on the steel rope loop are connected end to end along the circular path, which is the Ouroboros movement mode.

[0050] like Fig.10As shown, it is an implementation method of the towing mechanism 9: a roller with a pattern cast on the surface and with a rotating power surrounds and presses the rope loop, and when the roller rotates, the rope bundle is dragged and pulled out from the main rotating frame 1 by friction; the surrounding roller also has a function of centering the rope bundle, that is, by surrounding and clamping, the two lines of the center normal 203 of the rope bundle cross section and the main rotating axis 201 are made collinear.

[0051] The number of towing mechanisms 9 can be more than one group to ensure the necessary dragging and extraction friction; in order to increase the friction, the towing mechanism 9 can be equipped with commercial and general modified additional towing power and facilities and equipment, such as power machinery, towing chains, reciprocating one-way towing hooks, vehicles, etc.

[0052] The semi-finished steel rope ring is dragged by the towing mechanism 9, and the rope strands in the through area of ​​the main rotating frame 1 are pulled. When the entire steel rope ring moves in the shape of a ouroboros, the rope strands to be woven are held along the normal line 203 of the rope bundle cross section to perform winding and weaving actions; at the same time, the rope strands rotate to perform twisting actions; the above three actions are superimposed and repeated to complete the winding and weaving process of the entire rope ring. The pitch and twisting parameters of the rope strands helically wound along the rope core of the steel rope ring product parameters are determined by the production and technical personnel according to the order and production outline; the rope ring body to be wound and knotted is arranged horizontally during the production process.

[0053] Preparatory work: the rope strands to be wound are pre-wound in the rope strand storage reel 4, which is placed in the bracket 3 and connected through the core shaft 5; according to the length of the wire rope loop 10 required by the production outline, that is, the length of the rope bundle center loop 204, one end of the rope strand is pulled out through the front hollow shaft head 7, and then horizontally wound back to enter the through area 501 inside the main rotating frame, and enter the through area 501 from the side opposite to the front hollow shaft head 7 and then pass through to connect into a ring as the rope core 301; the subsequent rope strands 302 will be passed through and coiled around the rope core 301;

[0054] When the main rotating frame 1 rotates about the main rotating axis 201, that is, rotates along the center line of the two outer edges 2 as the axis, the main rotating frame 1 holds the rack 3 and wraps the rope bundle 303 around the normal line of the center of the wire bundle cross section as the axis to perform a vortex ring, so that the rope strands are wound and woven on the rope loop; the front hollow shaft head 7 allows the rope strands 302 to pass through the hollow part and be wound on the rope loop; the towing mechanism 9 drags out the rope strands 302 in the through area 501, and at the same time unwinds the rope strands 302 from the rope strand storage reel 4, and winds and weaves them on the rope bundle 303; the rotation speed of the rack 3 about the rack rotating axis 202 is independent of the rotation speed of the main rotating frame 1 and can be set separately by the operator to obtain the required product performance effect.

[0055] The equipment structure of this embodiment abandons the traction guide wheel and the traction guide wheel's support for the wire rope loop, avoiding the limitation on the cross-sectional diameter of the rope loop. Therefore, without making any changes, the cross-sectional range of the processed steel rope loop can reach n0mm-1000+mm (value range: n∈1-9).

[0056] One parameter for assessing the production capacity of the equipment is: the minimum length that can be achieved when the cross-sectional diameter is large. The minimum length of the rope loop: At the same time, there is no internal support restriction of the traction guide wheel. Under any cross-sectional diameter, even when the cross-sectional diameter is large, the minimum length of the rope loop can be minimized, that is, the length of the minimum loop that passes through the through hole of the rotation center of the equipment and returns to form a head-to-tail connection. The maximum length of the wire rope loop: It is not limited by the equipment and only depends on the size of the site. Under the traction of the towing mechanism 9, the rope loop and rope bundle part passes through the main body of the equipment and is laid flat on the hardened work site in a free state in a serpentine coil manner. During processing, there is no need for huge tensioning force to open the rope loop to be processed, and the load-bearing mechanical structure is eliminated, and the structure is simple and reliable.

[0057] An important parameter for measuring the wire rope loop is that when it is freely laid, the line connecting the center points of the rope bundle cross section must be on the same plane, that is, there must be no irreversible internal stress that causes an 8-shaped twist or twisting trend. The technical solution is that when the rope bundle body is wound along the vortex ring path, the rope strands are twisted at the same time.

[0058] Twisting is the twisting of the strands during the winding movement. The internal stress generated by the twisting and the deformation stress generated by the knotting and weaving cancel each other out. The twisting direction can be clockwise or counterclockwise, or it can be zero. It is determined by the production and design personnel based on the mechanical properties of the strands, product parameters, and test experiments.

[0059] The twisting action in this equipment is: 1. The rope strands are coiled around the central axis of the rope bundle cross section; 2. The frame holds the rope strand reel and rotates; 3. At the same time, the rope bundle is dragged and moved, and the three actions are superimposed to complete the twisting action. The rope ring to be wound and coiled during the production process is arranged horizontally. No supporting structure is required, and steel wire rope ring products with large single length weight, large cross-sectional diameter, and softness can be processed. The resulting effect is: industrialized mass production of heavy and extra-large steel wire rope rings becomes possible, with high production efficiency and product quality, and reduced labor intensity.

[0060] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
