Description

Technical Field

[0001] This utility model relates to the field of lifting rotating ring technology, specifically a lifting rotating ring disassembly device. Background Technology

[0002] A swivel eye, also known as a universal eye, swivel eye bolt, or swivel eye screw, is a lifting tool used in lifting operations. It is suitable for special lifting situations with angles. A swivel eye disassembly device is a tool or equipment specifically used to disassemble swivel eye. When a swivel eye is difficult to disassemble due to long-term use, corrosion, seized threads, etc., this device is used to apply external force to the eye or its connecting bolts, separating the eye from the connected parts so that the eye can be maintained, repaired, inspected, or replaced.

[0003] However, existing lifting ring disassembly devices lack the function of labor-saving disassembly. When in use, they mostly rely on wrenches to clamp the top of the ring or its connecting bolts, with the thumb and forefinger facing up or down, and rotate vertically, which is inconvenient to apply force. Furthermore, if the ring is difficult to disassemble due to rust, seized threads, or other reasons, the traditional disassembly method makes it even more difficult to disassemble the ring body due to the difficulty in applying force, affecting subsequent work. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting rotating ring disassembly device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lifting and rotating ring disassembly device includes a placement ring, a support assembly slidably connected to the top of the placement ring, a bidirectional lead screw rotatably connected to the side of the support assembly near the center of the placement ring, a clamping plate sleeved on the outer surface of the bidirectional lead screw, a protective pad fixedly connected to the side of the two clamping plates close to each other, abutting the lifting ring body on the side of the protective pad away from the clamping plate, and a handle fixedly connected to the side of the support assembly away from the bidirectional lead screw.

[0007] Preferably, the support assembly includes an upper arc block, a bidirectional lead screw is rotatably connected inside the upper arc block, a support rod is fixedly connected to the bottom of the upper arc block, a lower arc block is fixedly connected to the bottom end of the support rod, and a ring groove is formed on the placement ring, with the lower arc block slidably connected to the inner wall of the ring groove.

[0008] Preferably, a plurality of anti-slip rings are fixedly connected to the outer surface of the grip, and a plurality of suction cups are fixedly connected to the bottom of the placement ring.

[0009] Preferably, one of the two upper arc blocks has a rotating groove, a motor is fixedly connected to the inner wall of the rotating groove, and a bidirectional lead screw is fixedly connected to the output shaft of the motor.

[0010] Preferably, each of the clamps is internally fitted with two bidirectional lead screws.

[0011] Preferably, the distance between the two bidirectional lead screws is greater than the width of the lifting ring body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This lifting and rotating ring disassembly device, through the arrangement of a placement ring, a support assembly, a double-acting screw, and a clamping plate, allows for easy disassembly. In use, the placement ring is placed on the surface of the object to be lifted and pressed down. The motor is started to drive the double-acting screw to rotate, clamping the protruding part of the ring body. Both hands hold one handle and press down, rotating the entire support assembly. This causes the lower arc block to slide within the placement ring, rotating the ring body. As the ring body rotates, its bolts rotate inside the object to be lifted, gradually unscrewing. The method of disassembling the ring body is changed from vertically clamping the protruding part of the ring body to horizontally rotating around the protruding part, making it easier for workers to apply force and achieve a smoother unscrewing effect. This also facilitates the easy disassembly of rings that are difficult to unscrew due to rust.

[0014] 2. This lifting rotating ring disassembly device, through the setting of anti-slip ring and suction cup, increases the friction between the palm and the handle during use, avoids slippage and facilitates the application of force; the setting of suction cup fixes the placement ring to the surface of the lifted object, prevents it from moving, and facilitates the subsequent application of force to disassemble the lifting ring body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A lifting and rotating ring disassembly device includes a placement ring 1, a support assembly 2 slidably connected to the top of the placement ring 1, a double-acting screw 3 rotatably connected to the side of the support assembly 2 near the center of the placement ring 1, a clamping plate 4 sleeved on the outer surface of the double-acting screw 3, a protective pad 5 fixedly connected to the side of the two clamping plates 4 that are close to each other, and a lifting ring body 6 abutting the side of the protective pad 5 away from the clamping plate 4. A handle 7 is fixedly connected to the side of the support assembly 2 away from the double-acting screw 3. The placement ring 1 is placed on the surface of the object to be lifted and pressed down, driving the double-acting screw 3 to rotate and clamp the protruding part of the lifting ring body 6. One handle 7 is held by each hand and pressed down, rotating the entire support assembly 2, causing the lower arc block 10 to move inside the placement ring 1. The sliding mechanism drives the rotating ring body to rotate. As the rotating ring body rotates, its bolts rotate inside the lifted load and gradually unscrew. The method of disassembling the lifting ring body 6 by changing the vertical clamping and twisting of the wrench around the protrusion of the lifting ring body 6 is changed to horizontal rotation around the protrusion of the lifting ring body 6. This makes it easier for the workers to exert force and achieve the effect of unscrewing the lifting ring body 6 more easily. This also makes it easier to disassemble the lifting ring body 6 that is difficult to unscrew due to rust. In cases where the lifting ring body 6 is difficult to disassemble due to rust or corrosion, this device can initially twist the lifting ring body 6. Subsequent unscrewing does not require much force. Moreover, during the unscrewing process, the bolt part of the lifting ring body 6 rises relative to the surface of the lifted load, and the suction cup 13 can meet the rising change.

[0023] In this embodiment, preferably, the support assembly 2 includes an upper arc block 8, a bidirectional lead screw 3 rotatably connected inside the upper arc block 8, a support rod 9 fixedly connected to the bottom of the upper arc block 8, a lower arc block 10 fixedly connected to the bottom end of the support rod 9, and an annular groove 11 is provided on the placement ring 1. The lower arc block 10 is slidably connected to the inner wall of the annular groove 11. In use, when the support body rotates, the upper arc block 8 drives the bidirectional lead screw 3 to rotate, and the lower arc block 10 slides in the annular groove 11. The cooperation between the support body and the annular groove 11 makes the structure of the device body stable and convenient for applying force. The cross-sectional gap of the annular groove 11 is convex, which locks the lower arc block 10, preventing it from detaching from the annular groove 11 and restricting it to slide only in the annular groove 11.

[0024] In this embodiment, preferably, a plurality of anti-slip rings 12 are fixedly connected to the outer surface of the handle 7, and a plurality of suction cups 13 are fixedly connected to the bottom of the placement ring 1. In use, the anti-slip rings 12 increase the friction between the palm and the handle 7, preventing slippage and facilitating the application of force; the suction cups 13 fix the placement ring 1 to the surface of the object being lifted, preventing it from moving and facilitating the subsequent disassembly of the lifting ring body 6. The anti-slip rings 12 and the suction cups 13 are both made of silicone, which is a prior art and will not be explained in detail here.

[0025] In this embodiment, preferably, one of the two upper arc blocks 8 has a rotating groove 14. A motor 15 is fixedly connected to the inner wall of the rotating groove 14. The output shaft of the motor 15 is fixedly connected to a bidirectional lead screw 3. In use, the motor 15 is started to drive the bidirectional lead screw 3 to rotate, clamping the protruding part of the lifting ring body 6. Both hands hold one handle 7 and press down, rotating the entire support assembly 2, causing the lower arc block 10 to slide in the placement ring 1, and causing the rotating ring body to rotate. The motor 15 is located inside the upper arc block 8, so it will not affect the overall balance of the rotating support and facilitates subsequent force application.

[0026] In this embodiment, preferably, each clamping plate 4 has two bidirectional lead screws 3 inserted inside. In use, the motor 15 is started to drive the bidirectional lead screws 3 to rotate, clamping the protruding part of the lifting ring body 6. Both hands hold one handle 7 and press down, rotating the entire support assembly 2, causing the lower arc block 10 to slide inside the placement ring 1, driving the rotating ring body to rotate. The clamping plate 4 has two identical bidirectional lead screws 3 inserted inside, which can evenly clamp the top protrusion of the lifting ring body 6 when the two clamping plates 4 approach each other and clamp the lifting ring body 6, ensuring uniform force application afterward.

[0027] In this embodiment, preferably, the distance between the two bidirectional lead screws 3 is greater than the width of the lifting ring body 6. When in use, the start motor 15 drives the bidirectional lead screws 3 to rotate, clamping the protruding part of the lifting ring body 6. Hold one handle 7 with both hands and press down, rotate the entire support assembly 2, causing the lower arc block 10 to slide inside the placement ring 1, thereby causing the rotating ring body to rotate. This arrangement ensures that the two clamping plates 4 can fully clamp the top protrusion of the lifting ring body 6, facilitating subsequent unscrewing.

[0028] Working principle: In this embodiment, a lifting rotating ring disassembly device is used when the placement ring 1 is placed on the surface of the object to be lifted and pressed down. The motor 15 is started to drive the bidirectional lead screw 3 to rotate, clamping the protruding part of the ring body 6. Both hands hold one handle 7 and press down, rotating the entire support assembly 2, causing the lower arc block 10 to slide inside the placement ring 1, driving the rotating ring body to rotate. When the rotating ring body rotates, its bolts rotate inside the object to be lifted, gradually unscrewing. By changing the method of disassembling the ring body 6 by vertically clamping the protrusion of the ring body 6 with a wrench, it is changed to horizontally rotating around the protrusion of the ring body 6, which makes it easier for the operator to exert force and achieve the effect of more easily unscrewing the ring body 6. This also makes it easy to disassemble the ring body 6 that is difficult to unscrew due to rust.
