Description

Technical Field

[0001] This invention relates to the field of wire rope sling welding technology, and in particular to a wire rope sling connection and welding device. Background Technology

[0002] In industrial lifting, hoisting, and traction fields, wire rope slings are widely used for connecting and securing various heavy equipment due to their high strength, tensile strength, and abrasion resistance. The reliability of wire rope sling connections directly affects the safety of production operations. Welding is the core process in wire rope sling connection, mainly used for sealing wire rope ends, butt joints, and securing sling accessories.

[0003] Currently, existing wire rope sling welding equipment, in practical applications, is prone to thermal damage to the wire rope slings due to the high temperatures generated during welding. This leads to wire annealing, coarse grains, and reduced strength. Simultaneously, the rope core is easily melted and carbonized, resulting in problems such as loosening, embrittlement, and wire breakage, severely impacting the sling's service life and load-bearing safety. Existing water cooling methods are mostly simple methods like wrapping with a damp cloth or direct dripping water, which have limited cooling range, uneven cooling effect, and are prone to water loss and displacement, failing to form a stable heat-insulating cooling zone and effectively blocking heat conduction to the rope body.

A fixing plate is fixedly installed inside the limiting plate. A viscoelastic damper is provided between the fixing plate and the roller shaft support to buffer radial vibration without interfering with the rotation of the rollers.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention utilizes a powerful cooling component and water circulation design in its water-cooling mechanism. The wet cotton block on the surface of the fixed cylinder can closely adhere to the wire rope rigging body, forming a stable heat insulation and cooling zone. This effectively blocks the conduction of welding heat to the rope body, preventing wire annealing, core carbonization, and wire rope loosening and embrittlement. Simultaneously, the filter box on the water outlet pipe, in conjunction with the filter screen and agitator impeller in the water collection pipe, can filter impurities in the cooling water and automatically clean the filter screen, preventing blockage of the cooling channel, ensuring stable water cooling effect, and further reducing the impact of heat damage on the rigging strength.

[0017] 2. This invention uses the heating plate of the preheating box and the heat output ring to uniformly preheat the welding wire body, reduce the temperature difference between the welding wire and the molten pool, stabilize the arc, reduce spatter, and improve the penetration depth and filling effect. At the same time, the air inlet pipe and the convex plate work together to drive the cleaning plate to rotate, and the air intake pipe and the cavity of the preheating box are linked to realize airflow circulation, further cleaning impurities and preventing impurities from entering the molten pool and causing defects such as porosity and slag inclusions. In addition, the rotation of the cleaning plate drives the spiral scraper to rotate, which can efficiently scrape off the oxide scale and impurities on the surface of the welding wire, ensuring the density of the weld.

[0018] 3. The present invention uses a pressure plate and a spring in the strong cooling component to keep the wet cotton block pressed against the surface of the wire rope rigging body, ensuring cooling and fit. At the same time, the reinforcing ribs inside the wet cotton block improve its structural strength, and the friction plate on the surface further reduces frictional wear with the wire rope rigging body, extending the service life of the wet cotton block.

[0019] 4. The invention uses a motor to drive the first gear to rotate, which in turn drives the meshing gear ring and the second gear to move synchronously. This causes the welding frame and the welding plate to rotate synchronously, allowing for all-around welding of the steel wire rope rigging body that passes through the welding frame. This avoids incomplete welding and weak welding. At the same time, the annular wire feeding groove on the welding plate can stably store and feed the welding wire. Together with the wire feeding assembly and guide components, it ensures that the welding wire is accurately fed into the gaps between the multiple steel wires, giving full play to the reinforcing effect of the filler welding and improving the firmness of the rigging connection.

[0020] 5. This invention uses a limiting plate and rollers to precisely limit the movement of the wire rope rigging body. The rolling of the rollers reduces frictional damage to the rigging surface during the limiting process. Furthermore, the viscoelastic damper between the fixing plate and the rollers effectively buffers the vibration generated during welding, preventing the rigging from swaying or shifting and ensuring welding accuracy. At the same time, the adjusting components can flexibly adjust the tightness of the rigging to adapt to different specifications of wire rope rigging, improving the versatility of the equipment.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 - 9. This invention provides a connection and welding device for wire rope slings, including a support frame 1. A welding repair mechanism 4 is provided at the top of the support frame 1. The welding repair mechanism 4 includes a welding frame 44 rotatably mounted at the top of the support frame 1. A wire rope sling body 2 passes through the middle of the welding frame 44. A water cooling mechanism 5 is provided inside the welding frame 44 near the wire rope sling body 2. The water cooling mechanism 5 includes a water pump 54 fixedly mounted at the bottom of the support frame 1. A strong cooling component 53 is provided inside the welding frame 44 near the wire rope sling body 2. The device includes a fixed cylinder 531 fixedly installed inside the welding frame 44. The surface of the fixed cylinder 531 near the wire rope sling body 2 is provided with a wet cotton block 537 for reducing the temperature of the wire rope sling body 2. The wet cotton block 537 is made of high temperature resistant modified fiber. A water collection pipe 532 is connected to the top of the fixed cylinder 531. The output end of the water pump 54 is connected to the inside of the water collection pipe 532 through the water inlet pipe 51. The input end of the water pump 54 is connected to the inside of the fixed cylinder 531 through the water outlet pipe 52. A filter box 55 is provided on the water outlet pipe 52.

[0033] First, the water pump 54 of the water cooling mechanism 5 is started. The water pump 54 starts working and drives the cooling water to form a closed loop circulation. The output end of the water pump 54 delivers the cooling water to the water collection pipe 532 through the water inlet pipe 51. The water collection pipe 532 evenly distributes the cooling water into each fixed cylinder 531. After the wet cotton block 537 on the surface of the fixed cylinder 531 absorbs the cooling water, it tightly adheres to the welding area and surrounding area of ​​the wire rope rigging body 2. Then, the repair welding mechanism 4 is started. The welding frame 44 slowly rotates around the wire rope rigging body 2 to achieve repair welding of the wire rope. The high temperature generated during the circumferential welding of the rigging body 2 is absorbed by the cooling water in the wet cotton block 537. The surface temperature of the wire rope rigging body 2 is quickly reduced by the heat absorption of water evaporation. The cooling water after absorbing heat flows back into the fixed cylinder 531 and then flows back to the water pump 54 through the water outlet pipe 52. During the return flow, the filter box 55 on the water outlet pipe 52 filters the cooling water to remove impurities and prevent impurities from clogging the water flow channels of the water inlet pipe 51, water collection pipe 532 or fixed cylinder 531, ensuring continuous and stable water cooling circulation.

[0034] In some embodiments, an agitator 533 is rotatably mounted inside the water collection pipe 532, and a drive device for driving the agitator 533 is installed inside the water collection pipe 532. A filter screen 534 is fixedly mounted on the inner wall of the water collection pipe 532 near the fixed cylinder 531, and a rubber block for scraping impurities on the surface of the filter screen 534 is fixedly mounted on the surface of the agitator 533 near the filter screen 534.

[0035] When the water pump 54 drives the cooling water through the inlet pipe 51 into the collection pipe 532, the cooling water first flows through the filter screen 534 inside the collection pipe 532. The filter screen 534 performs secondary filtration of the cooling water, further removing fine impurities in the water and preventing impurities from entering the fixed cylinder 531 and clogging the water absorption channel of the wet cotton block 537. At the same time, the drive device inside the collection pipe 532 is activated, which drives the agitator impeller 533 to rotate at a constant speed. During the rotation of the agitator impeller 533, the rubber block fixed on its surface rotates synchronously, continuously scraping the surface of the filter screen 534 and scraping off the impurities intercepted by the filter screen 534, preventing impurities from accumulating on the filter screen 534 and causing clogging. Throughout the operation, the filter screen 534 continuously performs secondary filtration of the cooling water, and the agitator impeller 533 and the rubber block continuously achieve self-cleaning of the filter screen 534, ensuring that the cooling water remains clean and guaranteeing the stable operation of the water cooling mechanism 5.

[0036] In some embodiments, a pressure plate 536 is provided at the top of the fixed cylinder 531 on the wet cotton block 537, a spring 535 is fixedly installed between the pressure plate 536 and the fixed cylinder 531, multiple reinforcing ribs 538 are provided inside the wet cotton block 537, and a friction plate 539 for reducing friction damage is fixedly installed on the surface of the wet cotton block 537 near the steel wire rope rigging body 2.

[0037] Cooling water flows into the fixed cylinder 531 through the water collection pipe 532, and the wet cotton block 537 fully absorbs the cooling water, continuously cooling the wire rope rigging body 2 during the welding process. Due to the elastic compression of the spring 535, even if the wet cotton block 537 is slightly deformed after absorbing water or the surface of the wire rope rigging body 2 is slightly uneven, the wet cotton block 537 can always fit tightly against the wire rope rigging body 2, avoiding cooling dead zones. The multi-layer reinforcing ribs 538 inside the wet cotton block 537 provide support when the wet cotton block 537 is under pressure and absorbs water, preventing excessive deformation and damage, and extending its service life. During the welding process, when the welding frame 44 rotates, the friction plate 539 on the surface of the wet cotton block 537 contacts the surface of the wire rope rigging body 2. The friction plate 539 greatly reduces the friction between the wet cotton block 537 and the wire rope rigging body 2, preventing the wet cotton block 537 from wearing down the surface of the wire rope rigging body 2, and also reducing the wear of the wet cotton block 537 itself, ensuring the cooling effect of the strong cooling component 53.

[0038] In some embodiments, a toothed ring 43 is fixedly installed on the outer surface of the welding frame 44, a welding plate 48 is provided on the surface of the welding frame 44 near the wire rope rigging body 2, a second gear 47 is fixedly installed on the outer surface of the welding plate 48, a first gear 42 is rotatably installed on the top of the support frame 1, and the first gear 42 meshes with the second gear 47 and the toothed ring 43, and a motor 41 is fixedly installed on the top of the support frame 1, and the output end of the motor 41 meshes with the first gear 42.

[0039] The motor 41 at the top of the support frame 1 is activated, and the output of the motor 41 drives the first gear 42 to rotate at a constant speed. Since the first gear 42 meshes with the toothed ring 43 on the outer surface of the welding frame 44 and the second gear 47 on the outer surface of the welding plate 48, the rotation of the first gear 42 synchronously drives the toothed ring 43 and the second gear 47 to rotate, thereby driving the welding frame 44 and the welding plate 48 to rotate synchronously around the wire rope rigging body 2. During the rotation of the welding frame 44, the strong cooling component 53 inside it rotates synchronously, realizing all-round cooling of the welding area of ​​the wire rope rigging body 2. At the same time, the welding plate 48 rotates synchronously with the welding frame 44, and the welding components on the welding plate 48 perform circumferential welding on the wire rope rigging body 2 to ensure that there are no dead corners in the welding part of the wire rope rigging body 2. During the welding process, the gear transmission structure remains stable at all times to ensure the synchronous rotation of the welding frame 44 and the welding plate 48, avoid welding misalignment, and ensure the uniformity and firmness of the connection welding of the wire rope rigging body 2.

[0040] In some embodiments, an annular wire feeding groove is provided on the outer surface of the welding plate 48, and a welding wire body 46 is wound inside the wire feeding groove. One end of the welding wire body 46 penetrates the interior of the welding plate 48 and is used for supplementary welding when welding the wire rope sling body 2.

[0041] In this process, the welding plate 48 rotates synchronously with the welding frame 44. When the welding plate 48 rotates, the annular wire feeding groove limits the welding wire body 46, preventing it from becoming scattered or tangled. Simultaneously, under the welding pressure and the cooperation of the wire feeding assembly 45, the welding wire body 46 is slowly released from the wire feeding groove and simultaneously conveyed to the welding part of the wire rope rigging body 2 through one end of the welding plate 48. During the repair welding process, the welding wire body 46 is continuously conveyed to the weld seam to fill the weld gap, enhance the weld strength, and ensure that the multiple strands of steel wire are firmly fused. Since the wire feeding groove is annular and matches the rotation trajectory of the welding plate 48, it can achieve uniform and stable feeding of the welding wire body 46, avoiding the accumulation of the welding wire body 46 due to excessively fast feeding and insufficient feeding due to excessively slow feeding, thus improving the accuracy of the repair welding.

[0042] In some embodiments, a wire feeding assembly 45 is provided on the surface of the welding frame 44. The wire feeding assembly 45 includes a preheating box 451 fixedly installed on the surface of the welding frame 44, and the welding wire body 46 slides through the preheating box 451. A plurality of heating plates 457 are fixedly installed inside the preheating box 451. A heat output ring 455 is provided on the surface of the heating plate 457 near the welding wire body 46, and the heating plate 457 is heated by a built-in heating device. A thermal expansion cylinder 453 is symmetrically arranged inside the preheating box 451, and a top plate is fixedly installed on one end of the thermal expansion cylinder 453 near the welding wire body 46.

[0043] In this preheating chamber 451, the heating plate 457 generates heat through an internal heating device. This heat is transferred to the heat output ring 455, which wraps around the welding wire body 46 in a ring shape, evenly distributing heat to the surface of the welding wire body 46 for low-temperature preheating. Simultaneously, the thermal expansion cylinder 453 inside the preheating chamber 451 gradually expands and contracts as the preheating temperature rises. As the temperature increases, the thermal expansion cylinder 453 extends, causing the top plate at the top to move towards the welding wire body 46 until the top plate is tightly pressed against the welding wire body. The surface of the heating plate 457 clamps and positions the welding wire body 46, preventing it from shifting or shaking during preheating. When the preheating temperature reaches the preset value, the heating plate 457 maintains a constant temperature, and the thermal expansion cylinder 453 maintains its telescopic state to ensure uniform preheating of the welding wire body 46. During the welding process, the preheating box 451 continues to work to maintain the preheating temperature of the welding wire body 46. The thermal expansion cylinder 453 adaptively adjusts the clamping force according to temperature changes to adapt to welding wire bodies 46 of different diameters, thereby improving the pretreatment quality of the welding wire body 46.

[0044] In some embodiments, a cleaning plate 458 is rotatably mounted inside the preheating box 451, and the welding wire body 46 slides through the cleaning plate 458. A spiral scraper 456 is fixedly mounted on the top of the cleaning plate 458, and the spiral scraper 456 scrapes the surface of the welding wire body 46. An air inlet pipe 459 is connected to the surface of the preheating box 451 near the cleaning plate 458 through an external air pump. A plurality of protrusions are fixedly mounted on the outer surface of the cleaning plate 458, and the air inlet pipe 459 pushes the cleaning plate 458 to rotate through the protrusions. An exhaust port is opened on the back of the preheating box 451.

[0045] The process involves activating an external air pump, which delivers airflow into the preheating chamber 451 via an air inlet pipe 459. The airflow directly impacts the raised plate on the outer surface of the cleaning plate 458. Under the impact of the airflow, the raised plate causes the cleaning plate 458 to rotate around the welding wire body 46. As the cleaning plate 458 rotates, the spiral scraper 456 fixed at its top rotates synchronously. The spiral scraper 456 closely adheres to the surface of the welding wire body 46. With the rotation of the cleaning plate 458, the spiral scraper 456 performs all-round, spiral scraping of the surface of the welding wire body 46, thoroughly removing oxide scale, floating rust, impurities, etc. from the surface of the welding wire body 46. Simultaneously, the welding wire body 46 slowly slides through the cleaning plate 458, ensuring that every section of the surface of the welding wire body 46 is scraped and cleaned by the spiral scraper 456. At the same time, the side wall of the preheating chamber 451 has exhaust holes. The airflow after blowing the raised plate carries the scraped impurities out through the exhaust holes to maintain the dynamic balance of the intake and exhaust pressure inside the preheating chamber 451.

[0046] In some embodiments, the inner wall of the preheating box 451 is provided with a cavity 452, and the input end of the air pump is connected to the interior of the cavity 452 through the suction pipe 454.

[0047] The air pump draws air to create a vacuum inside the cavity 452, thereby insulating the internal temperature of the preheating box 451, ensuring the stability of the internal temperature of the preheating box 451, and improving the continuous preheating effect of the welding wire body 46.

[0048] In some embodiments, the top of the support frame 1 is provided with an adjustment component 6 for adjusting the tightness of the wire rope sling body 2, and one side of the support frame 1 is provided with a guide component 7 for stably guiding and feeding the welding wire body 46.

[0049] Specifically, based on the diameter and specifications of the wire rope sling body 2, the adjusting component 6 at the top of the support frame 1 is adjusted to control the tightness of the clamping structure, firmly fixing the wire rope sling body 2 within the welding frame 44. This ensures that the wire rope sling body 2 does not shake or shift during welding, and adapts to different specifications of wire rope sling bodies 2. Simultaneously, the welding wire body 46 is passed through the guide component 7 on one side of the support frame 1. The angle and position of the guide component 7 are adjusted to ensure that the welding wire body 46 can be accurately aligned with the inlet of the preheating box 451 of the wire feeding assembly 45. This achieves the guiding and limiting of the welding wire body 46, preventing it from shifting or shaking, and ensuring that the welding wire body 46 can smoothly enter the preheating box 451 for pretreatment and subsequent welding.

[0050] In some embodiments, a limiting mechanism 3 is provided at the top of the support frame 1. The limiting mechanism 3 includes a limiting plate 31 fixedly installed at the top of the support frame 1. Multiple rollers 32 are rotatably mounted on the limiting plate 31 near the surface of the wire rope sling body 2, and the rollers 32 roll on the surface of the wire rope sling body 2. A fixing plate 33 is fixedly installed inside the limiting plate 31. A viscoelastic damper is provided between the fixing plate 33 and the rotating shaft support of the rollers 32 to buffer radial vibration without interfering with the rotation of the rollers 32.

[0051] The welding frame 44 rotates around the wire rope sling body 2. During the welding process, the wire rope sling body 2 experiences slight vibrations. At this time, the viscoelastic damper between the fixing plate 33 and the roller 32 starts to work, absorbing and buffering the vibrations generated by welding, preventing the vibrations from being transmitted to the wire rope sling body 2, and preventing problems such as shaking, displacement, and strand breakage caused by vibrations. At the same time, when the welding frame 44 rotates, the wire rope sling body 2 remains relatively stationary. The roller 32 rolls on the surface of the wire rope sling body 2 as the welding frame 44 rotates, greatly reducing the friction between the limiting plate 31 and the wire rope sling body 2, preventing wear on the surface of the wire rope sling body 2 during the limiting process, and providing a stable guarantee for high-quality welding.

[0052] Working principle: The wire rope sling body 2 is inserted through the welding frame 44 and initially positioned. The support frame 1 serves as the installation foundation for the entire equipment, providing stable support for all components such as the welding repair mechanism 4 and the water cooling mechanism 5. At this time, the water pump 54 of the water cooling mechanism 5 is started. The water pump 54 begins to work and drives the cooling water to form a closed-loop circulation. The output end of the water pump 54 delivers the cooling water to the water collection pipe 532 through the water inlet pipe 51. The water collection pipe 532 evenly distributes the cooling water into the interior of each fixed cylinder 531. After the wet cotton block 537 on the surface of the fixed cylinder 531 absorbs the cooling water, it tightly adheres to the welding area and surrounding area of ​​the wire rope sling body 2. Subsequently... The welding repair mechanism 4 is activated, and the welding frame 44 slowly rotates around the wire rope rigging body 2 to perform circumferential welding on the wire rope rigging body 2. The high temperature generated during the welding process is absorbed by the cooling water in the wet cotton block 537. The surface temperature of the wire rope rigging body 2 is quickly reduced by absorbing heat through water evaporation. The cooling water after absorbing heat flows back into the fixed cylinder 531 and then flows back to the water pump 54 through the water outlet pipe 52. During the return flow, the filter box 55 on the water outlet pipe 52 filters the cooling water to remove impurities and prevent impurities from clogging the water flow channels of the water inlet pipe 51, water collection pipe 532, or fixed cylinder 531, ensuring continuous and stable water cooling circulation.

[0053] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
