Description

Technical Field

[0001] This invention relates to the field of forging equipment technology, specifically to a forging equipment and process for anti-rotation steel wire rope for deck cranes. Background Technology

[0002] Deck cranes are lifting equipment used on ships. The steel wire ropes required for these cranes need to have anti-rotation and stable corrosion resistance. During the production process, if the internal stress of the steel wire rope is not fully released after twisting, it will be prone to bending and twisting, resulting in poor anti-rotation performance. Existing technology, such as the steel wire rope forging and forming device disclosed in Chinese Patent CN207057549U, describes a steel wire rope forging method that releases stress by "using a motor to drive a rotating rod, which in turn drives a gear, which in turn drives a rack to move up and down, while a U-shaped slider drives the rack to slide on a slide rail, thereby driving the forging device to forge the steel wire rope."

[0003] However, it can only drive the forging device to move up and down through the gear and rack structure to hammer and forge the wire rope. Not only can it not automatically change direction in the circumferential direction for forging, but the single forging device also moves up and down, resulting in low processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-rotation wire rope forging device and process for deck cranes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a forging device for anti-rotation wire ropes for deck cranes, comprising a rotating drum frame and a main rotating drum that is limited and installed in the rotating drum frame. The main rotating drum is rotatable relative to the rotating drum frame. An expanding cam is provided on the main rotating drum, and a forging hammer is inserted through the side wall of the expanding cam. The expanding cam and the forging hammer are in sealed contact. A reversing gear is fixedly provided on the outside of the expanding cam, and a hammering spring is provided on the outside of the forging hammer. Pressure is applied to the forging hammer by the hammering spring, causing the forging hammer to... There is a tendency to move towards the axis of the expanded diameter protrusion; the outside of the main rotating drum is also fitted with a forging toothed disc that can rotate relative to the main rotating drum. The surface of the forging toothed disc is fixedly provided with a beveled block. When the forging toothed disc drives the beveled block to rotate relative to the main rotating drum, the beveled block can intermittently move the forging hammer, causing the forging hammer to move intermittently away from the axis of the expanded diameter protrusion; a drive shaft is also rotatably installed in the rotating drum frame. The drive shaft can drive the reversing toothed disc and the forging toothed disc, and the rotation speed of the forging toothed disc is greater than that of the reversing toothed disc.

[0006] A fixed pressure sleeve is fixedly installed on the surface of the reversing gear plate. The forging hammer passes through the fixed pressure sleeve. A spring pressure ring is fixedly installed on the surface of the forging hammer. The hammering main spring is located between the fixed pressure sleeve and the spring pressure ring to apply pressure to the forging hammer. A prying pin is replaceably fixedly installed on the spring pressure ring. When the forging gear plate drives the inclined prying block to rotate relative to the main rotating drum, the inclined prying block makes squeezing contact with the prying pin to realize intermittent prying of the forging hammer.

[0007] The drive shaft is coaxially fixed with a first gear and a second gear. The first gear meshes with the reversing gear plate, and the second gear meshes with the forged gear plate. The diameter of the first gear is smaller than the diameter of the second gear.

[0008] The forging hammer has a cylindrical inner cavity, a spray hole, and a suction chamber, which are interconnected. A piston is installed inside the cylindrical inner cavity, and the piston is in sealed contact with the inner wall surface of the cylindrical inner cavity. A connecting tube is fixedly installed on the piston, and the other end of the connecting tube is sealed and inserted into the spray hole. The side of the piston facing the suction chamber is connected to the spray hole through the connecting tube.

[0009] A return spring is provided on the side of the piston facing the suction chamber. A first one-way valve is embedded in the piston, which allows the oil in the cylindrical inner cavity to flow unidirectionally toward the connecting tube. A second one-way valve is embedded in the suction chamber, which allows the oil in the suction chamber to flow unidirectionally toward the cylindrical inner cavity.

[0010] A trigger pressure groove is formed through the side wall of the cylindrical inner cavity. A trigger pressure rod is fixedly installed on the connecting tube. The trigger pressure rod passes through the trigger pressure groove and extends outward. A limit pressure component is fixedly installed on the inner wall of the main rotating drum. When the forging hammer moves towards the wire rope for forging, before the forging hammer comes into contact with the wire rope, the trigger pressure rod will first make contact with the limit pressure component, causing the piston to move in the direction of the suction cavity, thereby causing the connecting tube to spray lubricating oil onto the surface of the wire rope through the spray hole.

[0011] The reversing gear disk has an annular cavity inside, and a flexible connecting pipe is provided between the annular cavity and the suction cavity. A sealing ring protrusion is coaxially fixed on the surface of the reversing gear disk, and the sealing ring protrusion is connected to the annular cavity. The outer sealing cover of the sealing ring protrusion is provided with an annular sealing cover, and the annular sealing cover is fixed relative to the rotating drum frame. When the reversing gear disk rotates, the sealing ring protrusion and the annular sealing cover rotate relative to each other and remain connected.

[0012] A buffer filter chamber is fixedly installed on the outside of the rotating drum frame. An output pipe is connected to the bottom of the buffer filter chamber, and the other end of the output pipe is connected to an annular sealing cover. A filter layer is provided in the buffer filter chamber, which can filter the lubricating oil in the buffer filter chamber.

[0013] The upper part of the buffer filter chamber is connected to a return pipe, and the other end of the return pipe is connected to an L-shaped ring cover. The L-shaped ring cover is fixedly mounted on the rotating drum frame. The L-shaped ring cover is in sealed contact with the outer surface of the expansion joint. A return wall hole is opened through the side wall of the expansion joint. The expansion joint and the L-shaped ring cover maintain sealed communication during relative rotation through the return wall hole.

[0014] A manufacturing process for an anti-rotation wire rope for a deck crane includes: first, twisting the inner and outer strands of the wire rope in opposite directions to cancel each other out; then, forging and compacting the rope using a forging machine to eliminate stress.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The forging equipment of the present invention, through its structural design, only requires the drive shaft to rotate, which enables the forging hammer to perform high-frequency hammering on the wire rope. During the hammering process, the forging hammer automatically rotates and reverses direction, realizing comprehensive forging of the wire rope and fully releasing the twisting stress.

[0016] 2. This invention, through the combination of a cylindrical inner cavity, piston components, and a buffer filter chamber, can spray lubricating oil through injection holes onto the contact surface between the wire rope and the forging hammer before each movement of the forging hammer towards the wire rope and before contact with the wire rope. The lubricating oil forms a thicker oil film in a short time, reducing the wear of the wire rope's coating during the hammering process and making the galvanized layer on the wire rope surface more complete. This invention is suitable for the salt spray environment during the operation of deck cranes at sea, ensuring the stable corrosion resistance of the forged wire rope. Attached Figure Description

[0029] 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.

[0030] Please see Figures 1 to 11 This invention provides a technical solution: a forging device for anti-rotation steel wire rope for a deck crane, comprising a rotating drum frame 1 and a main rotating drum 2 that is limited and installed in the rotating drum frame 1, such as... Figure 4As shown, an equipment base plate 101 is welded and fixed at the bottom of the rotary drum frame 1. The forging equipment of the present invention is fixed to the ground by the equipment base plate 101 and bolts to maintain the stability of the forging equipment.

[0031] The main rotating drum 2 can rotate relative to the rotating drum frame 1, such as Figure 5 As shown, a bearing is provided between the rotating drum frame 1 and the main rotating drum 2 to reduce the friction between the rotating drum frame 1 and the main rotating drum 2.

[0032] The main rotating drum 2 is provided with an expanding protrusion 3, the diameter of which is larger than the diameter of the main rotating drum 2. The expanding protrusion 3 is an annular protrusion protruding outward from the main rotating drum 2. A forging hammer 4 is inserted through the side wall of the expanding protrusion 3. The expanding protrusion 3 and the forging hammer 4 are in sealed contact to prevent lubricating oil from leaking through the gap between them. The expanding protrusion 3 and the forging hammer 4 are sealed by a rubber ring, which is embedded in the expanding protrusion 3. Figure 8 As shown in the image.

[0033] A reversing gear 5 is fixedly mounted on the outside of the expanding diameter protrusion 3, and a hammering main spring 6 is mounted on the outside of the forging hammer 4. The hammering main spring 6 applies pressure to the forging hammer 4, causing the forging hammer 4 to tend to move towards the axis of the expanding diameter protrusion 3. A forging gear 7, which can rotate relative to the main rotating cylinder 2, is also sleeved on the outside of the main rotating cylinder 2. Figure 5 As shown, the forging toothed disc 7 can only rotate relative to the main rotating cylinder 2 and cannot move axially relative to the main rotating cylinder 2. A beveled block 8 is fixedly provided on the surface of the forging toothed disc 7. When the forging toothed disc 7 drives the beveled block 8 to rotate relative to the main rotating cylinder 2, the beveled block 8 can intermittently move the forging hammer 4, causing the forging hammer 4 to move intermittently away from the axis of the expanded diameter protrusion 3.

[0034] like Figure 4 As shown, a drive shaft 9 is rotatably mounted in the rotating drum frame 1. The drive shaft 9 drives the reversing gear 5 and the forging gear 7, and the rotational speed of the forging gear 7 is greater than that of the reversing gear 5. A first gear 901 and a second gear 902 are coaxially fixed on the outside of the drive shaft 9. The first gear 901 meshes with the reversing gear 5, and the second gear 902 meshes with the forging gear 7. The diameter of the first gear 901 is smaller than the diameter of the second gear 902.

[0035] A fixed pressure sleeve 601 is fixedly installed on the surface of the reversing gear 5. The forging hammer 4 passes through the fixed pressure sleeve 601. A spring pressure ring 602 is fixedly installed on the surface of the forging hammer 4. The hammering main spring 6 is located between the fixed pressure sleeve 601 and the spring pressure ring 602 to apply pressure to the forging hammer 4. A movable pin 603 is replaceably fixedly installed on the spring pressure ring 602. When the forging gear 7 drives the inclined side block 8 to rotate relative to the main rotating drum 2, the inclined side block 8 makes intermittent contact with the movable pin 603 to achieve intermittent movement of the forging hammer 4. The movable pin 603 can be pulled out from the spring pressure ring 602 for replacement. When the movable pin 603 is worn, the equipment is maintained by replacing the movable pin 603.

[0036] like Figure 10 As shown, the forging hammer 4 has a cylindrical inner cavity 401, a jet hole 402, and a suction chamber 403 inside, which are interconnected. A piston 404 is installed inside the cylindrical inner cavity 401, and the piston 404 is in sealed contact with the inner wall surface of the cylindrical inner cavity 401. A connecting tube 405 is fixedly installed on the piston 404, and the other end of the connecting tube 405 is sealed and inserted into the jet hole 402. The side of the piston 404 facing the suction chamber 403 is connected to the jet hole 402 through the connecting tube 405.

[0037] A return spring 406 is provided on the side of the piston 404 facing the suction chamber 403. A first check valve 407 is embedded in the piston 404, which causes the oil in the cylindrical inner cavity 401 to flow unidirectionally into the connecting tube 405. A second check valve 408 is embedded in the suction chamber 403, which causes the oil in the suction chamber 403 to flow unidirectionally into the cylindrical inner cavity 401.

[0038] A trigger groove 409 is provided through the side wall of the cylindrical inner cavity 401. A trigger rod 410 is fixedly installed on the connecting tube 405. The trigger rod 410 extends outward through the trigger groove 409. A limit pressure member 411 is fixedly installed on the inner wall of the main rotating drum 2. When the forging hammer 4 moves towards the wire rope for forging, before the forging hammer 4 comes into contact with the wire rope, the trigger rod 410 will first make limited contact with the limit pressure member 411, causing the piston 404 to move towards the direction of the suction cavity 403, thereby causing the connecting tube 405 to spray lubricating oil onto the surface of the wire rope through the spray hole 402. Figure 5As shown, an inner wall mounting ring 201 is welded onto the inner wall of the main rotating drum 2. A rubber shield 202 is provided on one side of the inner wall mounting ring 201. A fixing ring 203 is provided on the side of the rubber shield 202 away from the inner wall mounting ring 201. The fixing ring 203 is fixed to the inner wall mounting ring 201 by screws, and the fixing ring 203 clamps and fixes the rubber shield 202. When the fixing ring 203 is removed, the rubber shield 202 can be easily replaced. Figure 5 As shown, the rubber shield 202 is a ring-shaped rubber sheet structure. The steel wire rope is placed through the central circular hole of the rubber shield 202. The rubber shield 202 can block the lubricating oil sprayed from the injection hole 402, preventing the lubricating oil from splashing everywhere. Two sets of rubber shields 202 are symmetrically arranged on both sides of the forging hammer 4 for front and rear blocking.

[0039] The reversing gear disk 5 has an annular cavity 413 inside. A flexible connecting pipe 412 is provided between the annular cavity 413 and the suction cavity 403. A sealing ring protrusion 414 is coaxially fixed on the surface of the reversing gear disk 5. The sealing ring protrusion 414 is connected to the annular cavity 413. The outer sealing cover of the sealing ring protrusion 414 is provided with an annular sealing cover 415. The annular sealing cover 415 is fixed relative to the rotating drum frame 1. When the reversing gear disk 5 rotates, the sealing ring protrusion 414 and the annular sealing cover 415 rotate relative to each other and remain connected.

[0040] A buffer filter chamber 416 is fixedly installed on the outside of the rotating drum frame 1. An output pipe 417 is connected to the bottom of the buffer filter chamber 416, and the other end of the output pipe 417 is connected to an annular sealing cover 415. Figure 6 As shown, a third check valve 422 is also installed on the output pipe 417. The third check valve 422 enables the lubricating oil in the buffer filter chamber 416 to flow unidirectionally towards the annular sealing cover 415, thereby preventing the lubricating oil in the annular sealing cover 415 from flowing back into the buffer filter chamber 416. In the downstream pipe to the right of the third check valve 422, it is ensured that the interior of the annular sealing cover 415 is filled with lubricating oil and will not flow back into the buffer filter chamber 416, so that the flexible connecting pipe 412 can still stably draw lubricating oil when rotated to a high position.

[0041] A filter layer 418 is provided in the buffer filter chamber 416, which can filter the lubricating oil in the buffer filter chamber 416. A return pipe 419 is connected to the upper part of the buffer filter chamber 416, and an L-shaped ring cover 420 is connected to the other end of the return pipe 419. The L-shaped ring cover 420 is fixedly mounted on the rotating drum frame 1. The L-shaped ring cover 420 is in sealing contact with the outer surface of the expanded diameter protrusion 3. A return wall hole 421 is opened through the side wall of the expanded diameter protrusion 3. The expanded diameter protrusion 3 and the L-shaped ring cover 420 maintain a sealed communication during relative rotation through the return wall hole 421.

[0042] A manufacturing process for an anti-rotation wire rope for a deck crane includes: first, twisting the inner and outer strands of the wire rope in opposite directions to cancel each other out; then, forging and compacting the rope using a forging machine to eliminate stress.

[0043] When using this invention, as Figure 4 As shown, the wire rope passes through the interior of the main drum 2 along its axis. The drive shaft 9 is connected to an external drive device, such as a motor. When the drive shaft 9 rotates, it drives the first gear 901 and the second gear 902 to rotate synchronously. The first gear 901 and the second gear 902 respectively drive the reversing gear disk 5 and the forging gear disk 7 to rotate. The diameter settings of the first gear 901, the second gear 902, the reversing gear disk 5, and the forging gear disk 7 ensure that the rotational speed of the forging gear disk 7 is greater than that of the reversing gear disk 5.

[0044] like Figure 8 As shown, the reversing gear 5, the expanding diameter protrusion 3, and the main rotating cylinder 2 are an integrated fixed connection structure. When the reversing gear 5 rotates, the expanding diameter protrusion 3 and the main rotating cylinder 2 rotate synchronously. Figure 5 As shown, when the rotational speeds of the reversing gear 5 and the forging gear 7 are different, relative rotation will occur between the main drum 2 and the forging gear 7. At this time, the forging gear 7 drives the inclined side block 8 to rotate relative to the main drum 2. The inclined side block 8 squeezes the actuating pin 603, pushing the forging hammer 4 to move away from the expansion joint 3, compressing the hammering main spring 6. After the inclined side block 8 passes the actuating pin 603, under the elastic force of the hammering main spring 6, the forging hammer 4 returns to its original position and hammers towards the axis of the expansion joint 3. Through the rotation of the forging gear 7 relative to the main drum 2, the forging hammer 4 performs high-frequency forging of the wire rope.

[0045] During the rotation of the forging toothed disc 7 relative to the main rotating drum 2, the main rotating drum 2 itself also rotates at a low speed. Through the low-speed rotation of the main rotating drum 2, the forging angle of the forging hammer 4 is cyclically adjusted in the circumferential direction to achieve comprehensive forging of the wire rope and fully release the twisting stress.

[0046] During the forging process described above, such as Figure 6 and Figure 10 As shown, when the forging hammer 4 moves towards the axis of the expanded diameter protrusion 3, the limiting pressure member 411 first limits and blocks the trigger pressure rod 410, as shown. Figure 10As shown, when the trigger lever 410 is limited by the limiting member 411, as the forging hammer 4 moves upward, the piston 404 moves downward relative to the forging hammer 4 inside the cylindrical inner cavity 401. At this time, the lubricating oil below the piston 404 is sprayed upward under high pressure through the first one-way valve 407 and the connecting tube 405, and then sprayed onto the surface of the wire rope through the spray hole 402. In a short time, a thick protective oil film is formed on the surface of the wire rope. When the forging hammer 4 comes into contact with the wire rope during forging, it can better protect the galvanized layer on the surface of the wire rope, reduce damage to the galvanized layer, and improve the corrosion resistance of the wire rope after forging. Each impact forging by the forging hammer 4 is preceded by the spraying of lubricating oil onto the surface of the wire rope through the spray hole 402.

[0047] After the forging hammer 4 strikes the metal, during the retraction process, the forging hammer 4 drives the trigger lever 410 away from the limiting pressure member 411. At this time, the trigger lever 410 loses the limiting pressure of the limiting pressure member 411, and under the restoring force of the return spring 406, as... Figure 10 As shown, the piston 404 moves upward relative to the forging hammer 4, creating a negative pressure below the piston 404. This negative pressure draws oil from the extraction chamber 403 through the second one-way valve 408, replenishing the area below the piston 404 and restoring it to its initial state.

[0048] like Figure 5 and Figure 6 As shown, the oil sprayed from the injection hole 402 accumulates between the two rubber baffles 202, located inside the expanded diameter protrusion 3. The lubricating oil then flows into the L-shaped ring cover 420 through the return wall hole 421, enters the buffer filter chamber 416 through the return pipe 419, filters the metal slag through the filter layer 418, enters the output pipe 417, and passes through the annular sealing cover 415, the sealing ring protrusion 414, the annular cavity 413 and the flexible connecting pipe 412 in sequence before being sucked back into the suction cavity 403, forming a complete circulation path.

[0049] In the above structure, the outer surfaces of the L-shaped ring cover 420 and the expanded diameter protrusion 3, as well as the annular sealing cover 415 and the sealing ring protrusion 414, can rotate relative to each other and maintain contact and sealing during rotation, thus completing the oil delivery without affecting the rotation of the reversing gear disk 5.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
