Description

Technical Field

[0001] The invention relates to the technical field of antistatic slings, and in particular to an antistatic high-strength fiber traction sling. Background Art

[0002] Fiber slings are ropes used for lifting made of synthetic fibers. Fiber slings may generate static electricity during use.

[0003] Fiber materials are prone to static electricity when subjected to friction, separation, etc. This is because the nuclei of different substances have different binding abilities to electrons. Under the action of friction, the electrons are transferred, making the object charged. If static electricity accumulates too much, it may cause discharge, which is very dangerous in an environment with flammable and explosive materials. For example, when fiber slings are used in industries such as petrochemicals, static electricity discharge may cause fire or explosion.

[0004] In order to avoid the hazards of static electricity in the prior art, the fiber slings need to be treated with anti-static treatment, such as using antistatic agents to treat the slings to form an antistatic protective layer on their surface, or maintaining a certain humidity in the working environment. However, the antistatic effect of this solution decreases quickly, the antistatic agent will continue to evaporate in the air, and the fiber slings will often rub during use, further leading to rapid consumption of the antistatic agent on the surface, thereby reducing the service life of the fiber slings and increasing safety risks.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figures 1 to 11 As shown: An anti-static high-strength fiber traction sling includes a lifting assembly 1, the lifting assembly 1 includes a frame 10, the frame 10 is used to support the lifting assembly 1, and the frame 10 can be installed on a beam to move horizontally, so as to realize the function of moving heavy objects. It also includes a lifting platform 2, a shell 21, a pair of fiber slings 22, a shaking assembly 3 and a humidifying assembly 4. The lifting platform 2 is installed on the frame 10 through the lifting assembly 1, and the fiber sling 22 and the lifting assembly 1 are connected through the lifting platform 2. The bottom of the fiber sling 22 is connected to the heavy object to realize the lifting of the heavy object. The shaking assembly 3 includes a rotating shaft 30, a slider 31, a rotating disk 32, a push block 33, a protruding rod 34, a pair of sliding rods 35 and two pairs of tension springs 36. The rotating shaft 30 is rotatably connected to the inner wall of the shell 21, the fiber sling 22 passes through the side wall of the shell 21 and is slidably connected thereto, the tops of the two fiber slings 22 are respectively fixedly connected to the two sides of the rotating shaft 30, the slider 31 passes through the lifting platform 2 and is slidably connected thereto, the bottom of the slider 31 is fixedly connected to the top of the shell 21, the sliding rod 35 is fixedly connected to the bottom of the lifting platform 2, the sliding rod 35 passes through the shell 21 and is slidably connected thereto, and the two pairs of tension springs 36 are fixedly connected to the bottom of the lifting platform 2. The springs 36 are respectively located at both ends of the shell 21, and the tension spring 36 is sleeved on the periphery of the slide rod 35. One end of the tension spring 36 is fixedly connected to the lifting platform 2, and the other end of the tension spring 36 is fixedly connected to the shell 21. The bottom of the turntable 32 is rotatably connected to the top of the lifting platform 2, and one end of the bottom of the push block 33 is rotatably connected to the eccentric part of the top of the turntable 32. One end of the protruding rod 34 is fixedly connected to the slider 31, and the other end of the protruding rod 34 conflicts with the push block 33. The side of the push block 33 close to the slider 31 is an arc structure, and the end of the push block 33 close to the turntable 32 is a flat structure. When the lifting is completed, through The lifting assembly 1 raises the lifting platform 2 to the bottom of the frame 10 to prevent the lifting platform 2 from moving, and then rotates the turntable 32 to drive the push block 33 to rotate counterclockwise. In this process, one side of the push block 33 first conflicts with the protruding rod 34, and because one side of the push block 33 is an arc-shaped structure, it will push the slider 31 to slowly drive the shell 21 to slide horizontally along the slide rod 35 on the lifting platform 2. The tension spring 36 of the shell 21 close to one end of the turntable 32 is stretched, and the tension spring 36 on the other side is contracted. As the turntable 32 continues to rotate, one end of the planar structure of the push block 33 moves to the protruding rod 34. The end of the push block 33 is pushed to separate the protruding rod 34 from the push block 33 quickly. At the moment when the push block 33 separates from the protruding rod 34, the tension spring 36 rebounds, driving the housing 21 to slide in the opposite direction quickly, causing the top of the limit sling to suddenly accelerate and translate, causing the fiber sling 22 to shake in a wave-like manner from top to bottom, thereby making the fiber sling 22 fully contact with the surrounding air through shaking, and the electrostatic charge is transferred and neutralized during the contact process. At the same time, the shaking action also helps to allow the charge accumulated on the fiber surface to leak into the surrounding environment, thereby eliminating the static electricity carried by the fiber sling 22 and improving safety. The humidification component 4 is installed on the housing 21, and the humidification component 4 is used to moisten the fiber sling 22.

[0036] like Figures 1 to 8 As shown: The shaking assembly 3 also includes a limit rod 37 and a first motor 38. The top of the first motor 38 is fixedly connected to the bottom of the lifting platform 2. The output shaft of the first motor 38 passes through the lifting platform 2 and is coaxially connected to the bottom of the turntable 32. When the first motor 38 is powered on, it can drive the turntable 32 to rotate, and shake the fiber sling 22 to remove static electricity. The bottom of the limit rod 37 passes through the lifting platform 2 and is slidably connected thereto. The top of the limit rod 37 passes through the other end of the push block 33 and is rotatably connected thereto. When the turntable 32 drives the push block 33 to rotate, one end of the push block 33 simultaneously drives the limit rod 37 to move horizontally on the lifting platform 2. The direction of the push block 33 is limited by the limit rod 37, so that the push block 33 always faces one side of the lifting platform 2, thereby ensuring that the protruding rod 34 can be quickly separated from the push block 33.

[0037] like Figures 1 to 8 As shown: The shaking assembly 3 also includes a plurality of clamping plates 39, the top of which is fixedly connected to the bottom of the frame 10, and a plurality of clamping slots 20 are provided on the top of the lifting platform 2, which are clamped and matched with the bottom of the clamping plates 39. After the lifting is completed, the fiber sling 22 is separated from the heavy object, and then the lifting platform 2 is raised, and the bottom of the clamping plate 39 is clamped into the clamping slot 20, thereby limiting the movement of the lifting platform 2, preventing the lifting platform 2 from being displaced under the action of inertia during the shaking process, and reducing the shaking force of the fiber sling 22.

[0038] like Figures 1 to 11 As shown: The humidifying assembly 4 includes a plane scroll spring 40 and a locking mechanism 41. The plane scroll spring 40 is wound around the outer periphery of the rotating shaft 30. One end of the plane scroll spring 40 is fixedly connected to the rotating shaft 30, and the other end of the plane scroll spring 40 is fixedly connected to the inner wall of the housing 21. The bottom of the fiber sling 22 is pulled to drive the rotating shaft 30 to rotate, thereby sliding out of the housing 21. At this time, the plane scroll spring 40 is stretched, and the fiber sling 22 can be stretched to facilitate the lifting work. After being released, the plane scroll spring 40 rebounds, driving the rotating shaft 30 to rotate, and the fiber sling 22 can be tightened to be wrapped around the outer periphery of the rotating shaft 30 for easy storage and protection. The locking mechanism 41 is installed on the housing 21, and the locking mechanism 41 is used to fix the rotating shaft 30.

[0039] like Figures 1 to 11 As shown: The locking mechanism 41 includes a first ratchet 410, a pawl 411, a round rod 412 and a torsion spring 413. The protrusion on the periphery of the first ratchet 410 conflicts with one end of the pawl 411. One side of the rotating shaft 30 passes through the side wall of the shell 21 and is coaxially connected to the first ratchet 410. The round rod 412 is fixedly connected to one side of the shell 21. The other end of the pawl 411 is rotatably connected to the periphery of the round rod 412. The torsion spring 413 is sleeved on the periphery of the round rod 412. One end of the torsion spring 413 is fixedly connected to the pawl 411, and the other end of the torsion spring 413 is fixedly connected to the shell 21. When the fiber sling 22 is stretched, the rotating shaft 30 rotates clockwise, driving the first ratchet 410 to rotate, and pushing the pawl 411 to rotate, and the torsion spring 413 is twisted. At this time, the rotating shaft 30 can rotate smoothly to release more fiber slings 22. After the stretching is completed, the torsion spring 413 rebounds and drives the pawl 411 to rotate around the round rod 412, and conflicts with the protrusion on the ratchet, so that the rotating shaft 30 cannot rotate, preventing the limiting sling from automatically retracting, which is convenient for fixing heavy objects and shaking. When the fiber sling 22 needs to be retracted, the rotating shaft 30 can be unlocked by simply rotating the pawl 411.

[0040] like Figures 1 to 11 As shown: The humidifying assembly 4 also includes a test kit 42, two pairs of licker-in rollers 43 and a liquid inlet mechanism 44. The test kit 42 is fixedly connected to one side of the housing 21, and the licker-in rollers 43 are rotatably connected to the inner wall of the housing 21. The opposite ends of the two pairs of licker-in rollers 43 are respectively in conflict with the top and bottom of the two fiber slings 22. One end of the licker-in rollers 43 is provided with a liquid injection groove 430 and is connected to the test kit 42. The test kit 42 is used to store antistatic agents, and the licker-in rollers 43 are used to fix the fiber slings 22. The spikes on the licker-in rollers 43 can penetrate the surface of the fiber slings 22. When the limit drive moves, the licker-in rollers 43 are driven to rotate, and the antistatic agent is injected into the fiber slings 22 through the liquid injection groove 430 to moisten them and further improve their antistatic performance. The liquid inlet mechanism 44 is installed on the housing 21, and the liquid inlet mechanism 44 is used to inject the antistatic agent in the test kit 42 into the licker-in rollers 43.

[0041] like Figures 1 to 11 As shown: The liquid inlet mechanism 44 comprises a pair of transmission shafts 440, a pair of blades 441, a pair of first gears 442, a toothed ring 443 and a support plate 444. One side of the support plate 444 is fixedly connected to the housing 21, the toothed ring 443 is rotatably connected to the inner wall of the support plate 444, the transmission shaft 440 is rotatably connected to the inner wall of the reagent box 42, the blades 441 are coaxially connected to the outer periphery of the transmission shaft 440, and the two blades 441 are respectively located at both ends of the reagent box 42. One side of the transmission shaft 440 passes through the inner wall of the reagent box 42 and is coaxially connected to the first gear 442, and the first gear 442 is meshed with the toothed ring 443. The toothed ring 443 is rotated, and the transmission shaft 440 is driven to rotate through the meshing transmission between the toothed ring 443 and the first gear 442, thereby driving the two blades 441 to rotate at the same time. Through the thrust provided by the blades 441, the antistatic agent in the reagent box 42 is respectively injected into the two pairs of licker-in rollers 43 through the injection groove 430, and enters the fiber sling 22 through the spikes on the licker-in rollers 43 to prevent static electricity from being generated.

[0042] like Figures 1 to 11 As shown: The liquid inlet mechanism 44 also includes a second ratchet 445, a plurality of teeth 446 and a plurality of thrust springs 447. The plurality of teeth 446 are distributed in a circle on the inner wall of the toothed ring 443. The inner wall of the toothed ring 443 is provided with a plurality of grooves 4430. One end of the teeth 446 is rotatably connected to the inner wall of the groove 4430. The other side of the rotating shaft 30 passes through the side wall of the shell 21 and the support plate 444 and is coaxially connected to the second ratchet 445. The toothed ring 443 is sleeved on the outer periphery of the second ratchet 445. The outer periphery of the second ratchet 445 conflicts with the other end of the teeth 446. One end of the thrust spring 447 is fixedly connected to the teeth 446, and the other end of the thrust spring 447 is fixedly connected to the inner wall of the groove 4430. When the shaft 30 rotates counterclockwise, the second ratchet 445 rotates and squeezes the tooth 446 to rotate. At this time, the thrust spring 447 is compressed. As the rotation continues, the thrust spring 447 pushes the tooth 446 to rotate and reset. The tooth ring 443 remains stationary, so that the liquid inlet mechanism 44 does not work when the fiber sling 22 is recovered, which can prevent the waste of reagents. When the fiber sling 22 is stretched to make the shaft 30 rotate clockwise, the ratchet and the pawl 411 collide with each other, driving the tooth ring 443 to rotate, so that the antistatic agent can be injected into the fiber sling 22.

[0043] like Figures 1 to 5 As shown: The lifting assembly 1 also includes a pair of rotating seats 11, a pair of winding rollers 12 and a pair of steel cables 13. The top of the rotating seat 11 is fixedly connected to the top wall of the frame 10, the winding roller 12 is rotatably connected to the rotating seat 11, one end of the steel cable 13 is fixedly connected to the outer periphery of the winding roller 12, and the other end of the steel cable 13 is fixedly connected to the top of the lifting platform 2. The two winding rollers 12 are rotated at the same time to drive the two steel cables 13 to tighten, so that the lifting platform 2 can be lifted for lifting, and the two steel cables 13 are respectively located on both sides of the lifting platform 2, so that the lifting platform 2 can be lifted steadily to reduce shaking and prevent the clamping plate 39 from deviating from the clamping slot 20.

[0044] like Figures 1 to 5 As shown: The lifting assembly 1 further includes a pair of second gears 14, a third gear 15 and a second motor 16. The top of the second motor 16 is fixedly connected to the top wall of the frame 10. The output shaft of the second motor 16 is coaxially connected to the third gear 15. The third gear 15 is meshed with the second gear 14. One end of the second gear 14 passes through the rotating seat 11 and is coaxially connected to the winding roller 12. The second motor 16 is powered on to work, driving the third gear 15 to rotate, and through the meshing transmission between the second gear 14 and the second gear 14, the two winding rollers 12 can be driven to rotate at the same time, thereby performing lifting and lowering operations.
