Description

Technical Field

[0001] The present invention specifically relates to a non-destructive oil sludge removal unit for tower crane steel ropes and a method for non-destructively removing oil sludge, belonging to the technical field of tower crane maintenance. Background Art

[0002] During the use of tower crane steel ropes, a layer of oil stain will accumulate. If not removed in time, it will affect their service life and traction ability. The oil stain will change the friction coefficient and reduce the traction ability, thus affecting the normal operation and safety of the tower crane. Therefore, the steel ropes on the tower crane need regular maintenance. Usually, butter is applied to the steel ropes. The main reasons for applying butter to tower crane steel ropes are as follows: Butter can form a lubricating film on the surface of the steel rope, reducing friction with components such as pulleys and drums, thereby reducing wear and extending the service life; at the same time, butter can form a protective layer to prevent rust caused by humid air, rainwater, etc., and can also prevent dust and dirt from adhering due to its viscosity, reducing the risk of wear and corrosion. In addition, in the absence of special steel rope lubricants, butter can be used as a temporary lubricant for emergency use.

[0003] However, the use of butter will generate oil sludge. During the use of butter, especially in high-temperature, humid or dusty environments, the oil in its components will gradually oxidize and deteriorate, and mix with dust, impurities in the air and metal particles generated during equipment operation, forming oil sludge. This oil sludge will adhere to the surface of the equipment, affecting the lubrication effect and even possibly causing equipment failures.

[0004] Therefore, in daily maintenance, not only should butter be applied to the steel ropes, but also the oil sludge on the surface of the steel ropes should be removed before applying butter. However, in actual steel rope maintenance, the removal of oil sludge on the surface of the steel ropes is usually not carried out, but butter is directly applied to the surface of the steel ropes, which will directly lead to the following disadvantages:

[0005] 1. The oil sludge blocks the newly applied butter from entering the interior of the steel rope, reducing the maintenance effect;

[0006] 2. The newly applied butter mixes with the oil sludge, affecting the lubrication effect of the butter;

[0007] 3. The butter is applied on the surface of the oil sludge, making the butter only adhere to the outer surface of the steel rope and easier to fall off. Summary of the Invention

[0011] As a preferred solution: The two outer convex ring bodies are arranged in parallel on the bottom support seat. Each outer convex ring body is slidably matched with the end of the bottom support seat. The bottom support seat includes a connecting block, a top seat, an elastic gasket, an elastic cushion block, a support plate, and two clamping screws. The top seat is arranged at the upper end of the connecting block. Arc-shaped sliding grooves for slidably matching with the outer convex ring bodies are respectively machined at both ends of the top seat. An elastic gasket is arranged on the inner wall of the connecting block. An adjustment screw hole is respectively machined on both sides of the connecting block. A clamping screw is correspondingly connected to each adjustment screw hole.

An elastic cushion block is arranged on one side of the support plate close to the elastic gasket. The outer wall shape of the elastic cushion block is matched with the inner wall shape of the elastic gasket.

[0012] As a preferred solution: A plurality of extrusion screw holes are machined on one side of the connecting block along its thickness direction. When the bottom support base is in the vertical clamping use state, the clamping screws are in the vertical use state, and each clamping screw passes through the pallet and is connected to its corresponding adjustment screw hole; when the bottom support base is in the horizontal clamping use state, the clamping screws are in the horizontal use state, and each clamping screw is arranged in the extrusion screw hole close to it.

[0013] As a preferred solution: Bolt holes are respectively machined at both ends of each arc-shaped outward convex edge, and bolts are arranged in the two bolt holes to enclose the two arc-shaped outward convex edges into an outward convex ring body.

[0014] As a preferred solution: The connecting block is replaced by a sleeve. A strip-shaped groove is machined on the inner wall of the sleeve along its thickness direction. The sleeve is sleeved on the shaft rod frame, and a strip-shaped protrusion is arranged on the shaft rod frame, and the strip-shaped protrusion is slidably arranged in the strip-shaped groove.

[0015] As a preferred solution: A support leg is respectively arranged at both ends of the shaft rod frame, and the orientations of the two support legs are the same. A disc body is arranged at the lower end of each support leg, and a plurality of positioning holes are machined on the upper end surface of the disc body along its circumferential direction; each support leg includes an upper cylinder part, a connecting bottom column, a telescopic column and an elastic part. A disc body is arranged at the lower end of the connecting bottom column, a telescopic column is arranged at the upper end of the connecting bottom column, the telescopic column is arranged in the cavity of the upper cylinder part, an elastic part is arranged in the cavity of the upper cylinder part, one end of the elastic part is in contact with the upper end surface of the telescopic column, and the other end of the elastic part is in contact with the inner wall of the cavity of the upper cylinder part.

[0016] A method for non-destructively removing oil sludge from the wire rope of a tower crane is realized by using the above non-destructive oil sludge removing unit. The non-destructive oil sludge removing unit is fixed on the iron frame structure below the wire rope of the tower crane. The self-splicing rotating cylinder is split into two halves. After one half of the arc-shaped outward convex edge of the self-splicing rotating cylinder is slidably installed in the arc-shaped chute, the cross-section of the arc-shaped outward convex edge is upward, and then the wire rope is arranged in the cavity of the self-splicing rotating cylinder. Then the other half of the self-splicing rotating cylinder is installed by bolts to form a complete cylinder body. Then the knob part is rotated, and the knob part drives the threaded rod to rotate. The threaded rod is threadedly connected to the slider. At this time, the threaded rod moves into the self-splicing rotating cylinder to complete the operation process of the threaded rod pushing the steel brush bristles against the wire rope. Through the positioning screws, the positions of each self-adjusting steel brush are adjusted one by one to ensure that the steel brush bristles are tightly attached to the outer wall of the wire rope, and the ends of the steel brush bristles are in a bent state, so that a plurality of self-adjusting steel brushes form a spiral track, and further a plurality of steel brush bristles form a spiral movement track in the self-splicing rotating cylinder that is the same as the spiral line of the wire rope. The tower crane operator operates the wire rope to unwind at a constant speed of 0.05 - 0.2 m / s. During the movement of the wire rope, it passes through the steel brush bristles, and a plurality of steel brush bristles will clean the oil sludge along the spiral line of the wire rope.

[0017] The beneficial effects of the present invention are as follows:

[0018] The non-destructive oil sludge removal unit in the present invention can be positioned at the position of the tower crane wire rope as needed, and realizes real-time cleaning of the oil sludge on the surface of the wire rope through the cooperation among the bottom support seat, the self-splicing rotating cylinder and multiple self-adjusting steel brushes. Among them, the structural form of the bottom support seat can be installed at the output position close to the wire rope on the tower crane according to the direction of the wire rope. The cooperation between the bottom support seat and the self-splicing rotating cylinder enables the self-adjusting steel brush to move along the helix of the wire rope during the process of cleaning the oil sludge on the surface of the wire rope, and realizes the process of synchronously and comprehensively cleaning and peeling off the oil sludge by relying on the use mode of the wire rope in the extended state. This can not only improve the uniform cleaning intensity of all positions in the circumferential direction of the wire rope, but also reduce the wear of the wire rope during the cleaning process, and realize the process of non-destructively cleaning the residual oil stains on the wire rope in a standardized manner. The installation positions of the non-destructive oil sludge removal unit on the tower crane are diverse, and it can be clamped on the tower crane as needed for oil sludge cleaning treatment. The non-destructive oil sludge removal method in the present invention is simple, the arrangement position can be adjusted as needed, and it can effectively and standardize the oil sludge removal operation process of the wire rope.

Detailed implementation manners

[0031] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] Detailed implementation manner one: In combination with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11To describe this embodiment, the lossless oil sludge removal unit in this embodiment includes a bottom-mounted support base 2, a self-assembling rotating cylinder 3, and a plurality of self-adjusting steel brushes 4. The self-assembling rotating cylinder 3 is slidably arranged on the bottom-mounted support base 2, and a plurality of self-adjusting steel brushes 4 are slidably arranged on the self-assembling rotating cylinder 3. Each self-adjusting steel brush 4 includes a knob member 4-1, a threaded rod 4-2, a slider 4-3, steel bristles 4-4, two positioning screws 4-5, and two side ears 4-6. One end of the knob member 4-1 is provided with a threaded rod 4-2. The threaded rod 4-2 is inserted into the slider 4-3 and is threadedly connected to the slider 4-3. One end of the threaded rod 4-2 is provided with steel bristles 4-4. The slider 4-3 is slidably arranged on the self-assembling rotating cylinder 3. One side ear 4-6 is respectively arranged on both sides of the slider 4-3 close to the end of the knob member 4-1. A positioning screw 4-5 is correspondingly inserted through each side ear 4-6. Each positioning screw 4-5 is threadedly connected to its corresponding side ear 4-6. The tip of the positioning screw 4-5 abuts against the outer wall of the self-assembling rotating cylinder 3. When the steel bristles 4-4 are in the use state, the threaded rod 4-2 is screwed in to push the steel bristles 4-4 to move inward along the radial direction of the self-assembling rotating cylinder 3. When the steel bristles 4-4 are in the unused state, the threaded rod 4-2 is screwed out to drive the steel bristles 4-4 to move outward along the radial direction of the self-assembling rotating cylinder 3.

[0033] Rotate the knob member 4-1. The knob member 4-1 drives the threaded rod 4-2 to rotate. The threaded rod 4-2 is threadedly connected to the slider 4-3. At this time, the threaded rod 4-2 moves into the self-assembling rotating cylinder 3, realizing that the threaded rod 4-2 pushes the steel bristles 4-4 to abut against the steel wire rope 5, achieving the adjustment of the cleaning force of the steel bristles 4-4 on the steel wire rope 5. When the threaded rod 4-2 drives the steel bristles 4-4 to move away from the steel wire rope 5, the purpose of controlling the actual number of steel bristles 4-4 in use is achieved.

[0034] Loosen the positioning screw 4-5. At this time, the slider 4-3 can freely slide in the adjusting arc-shaped groove 3-1-1, achieving the purpose of adjusting the position of the steel bristles 4-4. Through the positioning screw 4-5, the position of each self-adjusting steel brush 4 is adjusted one by one, so that a plurality of self-adjusting steel brushes 4 form a spiral track, and further a plurality of steel bristles 4-4 form a spiral track in the self-assembling rotating cylinder 3 that is the same as the spiral line of the steel wire rope 5. When the steel wire rope 5 is moving, a plurality of steel bristles 4-4 will clean the oil sludge along the spiral line of the steel wire rope 5, improving the cleaning effect. At this time, the arc-shaped convex edge 3-2 will rotate in the bottom-mounted support base 2, cooperating with the rotation generated by the movement of a plurality of steel bristles 4-4 along the spiral line of the steel wire rope 5 to improve the smoothness when cleaning the oil sludge.

[0035] After the steel wire brush 4-4 has been used for a period of time, the contact end of the steel wire brush 4-4 with the steel wire rope 5 will bend. At this time, the knob 4-1 can be rotated to drive the threaded rod 4-2 to rotate, thereby changing the direction of the end of the steel wire brush 4-4, making the tip of the steel wire brush 4-4 contact the surface of the steel wire rope 5 again and improving the utilization rate of the steel wire brush 4-4.

[0036] The present invention can be installed at the output position close to the steel wire rope 5 on the tower crane according to the running direction of the steel wire rope 5, and the configuration position is within the moving track range of the steel wire rope 5 on the tower crane, ensuring that the present invention can facilitate the coaxial threading position of the steel wire rope 5.

[0037] Specific Embodiment 2: This embodiment is a further limitation of Specific Embodiment 1. The self-splicing rotating cylinder 3 includes two arc-shaped shells 3-1 and four arc-shaped outer convex retaining edges 3-2. One arc-shaped outer convex retaining edge 3-2 is provided at each end of each arc-shaped shell 3-1. The arc-shaped outer convex retaining edge 3-2 is a semi-circular strip. The two arc-shaped shells 3-1 are arranged opposite to each other in parallel. When the two arc-shaped shells 3-1 make relative abutting movements, an inner threading hole 7 for fitting the steel wire rope 5 is formed by the inner walls of the two arc-shaped shells 3-1. Each arc-shaped outer convex retaining edge 3-2 is detachably connected to the other arc-shaped outer convex retaining edge 3-2 adjacent to it to form an outer convex ring body 8. A plurality of arc-shaped grooves 3-1-1 are machined on each arc-shaped shell 3-1 along its circumferential direction. At least one self-adjusting steel brush 4 is arranged in each arc-shaped groove 3-1-1. The slider 4-3 in each self-adjusting steel brush 4 reciprocates along the length direction of the arc-shaped groove 3-1-1 where it is located. The tip of the positioning screw 4-5 in each self-adjusting steel brush 4 abuts against the outer wall of the arc-shaped shell 3-1 where it is located.

[0038] One arc-shaped shell 3-1 and two arc-shaped outer convex retaining edges 3-2 form half of the outer convex ring body 8, which can realize the quick installation and disassembly of the outer convex ring body 8, help to open the outer convex ring body 8 to clean the sludge scattered in the inner threading hole 7, and is also more convenient to clean the sludge adhered to the steel wire brush 4-4. During the cleaning process, part of the sludge will also fall from the arc-shaped groove 3-1-1.

[0039] Embodiment 3: This embodiment is a further limitation of Embodiment 1 or 2. Two outwardly convex rings 8 are arranged in parallel on the bottom support base 2. Each outwardly convex ring 8 is slidably engaged with the end of the bottom support base 2. The bottom support base 2 includes a connecting block 2-1, a top seat 2-2, an elastic gasket 2-3, an elastic cushion block 2-4, a support plate 2-5 and two clamping screws 2-6. The upper end of the connecting block 2-1 is provided with a top seat 2-2. Arc-shaped sliding grooves 2-2-1 slidably engaged with the outwardly convex rings 8 are respectively machined at both ends of the top seat 2-2. An elastic gasket 2-3 is arranged on the inner wall of the connecting block 2-1. Adjusting screw holes 2-1-2 are respectively machined on both sides of the connecting block 2-1. A clamping screw 2-6 is correspondingly connected to each adjusting screw hole 2-1-2. Each clamping screw 2-6 passes through the support plate 2-5 and is detachably connected to its corresponding adjusting screw hole 2-1-2. An elastic cushion block 2-4 is arranged on one side of the support plate 2-5 close to the elastic gasket 2-3. The outer wall shape of the elastic cushion block 2-4 is matched with the inner wall shape of the elastic gasket 2-3.

[0040] Place the connecting block 2-1 on the pole of the tower crane so that the elastic gasket 2-3 contacts it. At this time, thread the clamping screw 2-6 into the adjusting screw hole 2-1-2, so that the support plate 2-5 moves towards the elastic gasket 2-3, and then the elastic cushion block 2-4 presses the pole of the tower crane, realizing the clamping and fixing of the non-destructive oil sludge removal monomer on the pole of the tower crane.

[0041] Embodiment 4: This embodiment is a further limitation of Embodiment 1, 2 or 3. A plurality of extrusion screw holes 2-1-1 are machined on one side of the connecting block 2-1 along its thickness direction. When the bottom support base 2 is in the vertical clamping use state, the clamping screw 2-6 is in the vertical use state, and each clamping screw 2-6 passes through the support plate 2-5 and is connected to its corresponding adjusting screw hole 2-1-2; when the bottom support base 2 is in the horizontal clamping use state, the clamping screw 2-6 is in the horizontal use state, and each clamping screw 2-6 is arranged in the extrusion screw hole 2-1-1 close to it.

[0042] When the installation position is a plate structure, after removing the elastic cushion block 2-4 and the support plate 2-5, install the connecting block 2-1 on the upper end of the plate. The clamping screw 2-6 is arranged in the extrusion screw hole 2-1-1, and the clamping screw 2-6 is threadedly connected to the extrusion screw hole 2-1-1, so that the end of the clamping screw 2-6 presses the plate, realizing the clamping and fixing of the whole non-destructive oil sludge removal monomer. Figure 2As shown, there are multiple screw holes 2-1-1 for extrusion. When the number of screw holes 2-1-1 for extrusion is four, the four screw holes 2-1-1 for extrusion are arranged in a matrix, that is, the four screw holes 2-1-1 for extrusion are respectively arranged at the four corner positions of a square matrix. Two clamping screws 2-6 are installed at their relative installation positions on two screw holes 2-1-1 in a diagonal relationship. This layout method can help improve the stability of the positioning of the two clamping screws 2-6 on the bottom support seat 2, and the number of the two clamping screws 2-6 can also be increased to further enhance the clamping stability.

[0043] Specific Embodiment 5: This embodiment further defines Embodiment 1, 2, 3, or 4. Bolt holes 3-2-1 are respectively machined at both ends of each arc-shaped outward convex rib 3-2. A bolt 9 is inserted into the two bolt holes 3-2-1 to enclose the two arc-shaped outward convex ribs 3-2 into an outward convex ring body 8. Connecting the two arc-shaped outward convex ribs 3-2 in the way of the bolt 9 can meet the quick disassembly and assembly requirements of the arc-shaped outward convex rib 3-2.

[0044] The working principle of this embodiment:

[0045] Fix the non-destructive oil sludge monomer on the iron frame structure below the tower crane steel wire rope 5. Split the self-splicing rotating cylinder 3 into two halves. After sliding one half of the arc-shaped outward convex rib 3-2 of the self-splicing rotating cylinder 3 into the arc-shaped chute 2-2-1, turn the cross-section of the arc-shaped outward convex rib 3-2 upward, then place the steel wire rope 5 in the cavity of the self-splicing rotating cylinder 3, and then install the other half of the self-splicing rotating cylinder 3 through the bolt 9 to form a complete cylindrical shape of the self-splicing rotating cylinder 3. Then rotate the knob part 4-1, and the knob part 4-1 drives the threaded rod 4-2 to rotate. The threaded rod 4-2 is threadedly connected to the slider 4-3. At this time, the threaded rod 4-2 moves into the self-splicing rotating cylinder 3, realizing that the threaded rod 4-2 pushes the steel brush bristles 4-4 against the steel wire rope 5. Through the positioning screw 4-5, adjust the position of each self-adjusting steel brush 4 one by one, so that the multiple self-adjusting steel brushes 4 form a spiral track, and further make the multiple steel brush bristles 4-4 form a spiral track in the self-splicing rotating cylinder 3 that is the same as the spiral line of the steel wire rope 5. The tower crane operator operates the steel wire rope 5 to perform a wire releasing operation. When the steel wire rope 5 moves, it passes through the steel brush bristles 4-4, and the multiple steel brush bristles 4-4 will clean the oil sludge along the spiral line of the steel wire rope 5, improving the cleaning effect, and thus achieving the purpose of removing the oil sludge on the steel wire rope 5 by the steel brush bristles 4-4.

[0046] Specific Embodiment 6: This embodiment further defines Embodiment 1, 2, 3, 4, or 5. The connecting block 2-1 is replaced by a sleeve 21. A strip-shaped groove 21-1 is machined along the thickness direction of the inner wall of the sleeve 21. The sleeve 21 is sleeved on the shaft rod frame 1, and a strip-shaped protrusion 1-1 is arranged on the shaft rod frame 1. The strip-shaped protrusion 1-1 is slidably arranged in the strip-shaped groove 21-1.

[0047] In this embodiment, the working principle of the shaft rod frame 1 in cooperation with the non-destructive oil sludge removal unit:

[0048] The shaft rod frame 1 is installed in front of the wire reel of the tower crane wire rope 5. With the pay-out or reeling-in operation of the wire rope 5, as the wire rope 5 undergoes a lateral displacement, correspondingly, the sleeve 21 can undergo a synchronous lateral displacement on the shaft rod frame 1.

[0049] Specific Embodiment Seven: This embodiment further limits Specific Embodiments One, Two, Three, Four, Five, or Six. A support leg 1-2 is respectively arranged at both ends of the shaft rod frame 1. The orientations of the two support legs 1-2 are the same. A disc body 1-3 is arranged at the lower end of each support leg 1-2. A plurality of positioning holes 1-3-1 are machined on the upper end surface of the disc body 1-3 along its circumferential direction; each support leg 1-2 includes an upper cylinder part 1-2-1, a connecting bottom column 1-2-2, a telescopic column 1-2-3, and an elastic member 1-2-4. A disc body 1-3 is arranged at the lower end of the connecting bottom column 1-2-2. The telescopic column 1-2-3 is arranged at the upper end of the connecting bottom column 1-2-2. The telescopic column 1-2-3 passes through the cavity of the upper cylinder part 1-2-1. The elastic member 1-2-4 is arranged in the cavity of the upper cylinder part 1-2-1. One end of the elastic member 1-2-4 is in contact with the upper end surface of the telescopic column 1-2-3, and the other end of the elastic member 1-2-4 is in contact with the inner wall of the cavity of the upper cylinder part 1-2-1.

[0050] Due to the pay-out or reeling-in operation of the wire rope 5, the vertical position of the wire rope 5 will change correspondingly by rising or falling. When the wire rope 5 descends, it presses on the shaft rod frame 1. At this time, the upper cylinder part 1-2-1 squeezes the elastic member 1-2-4, thereby shortening the support leg 1-2, achieving the purpose of reducing the vertical position of the self-splicing drum 3, and further reducing the friction between the wire rope 5 and the drum 3.

[0051] Specific Embodiment Eight: Combined with Figures 1 to 11Regarding this embodiment, the method for removing oil sludge without damage in this embodiment is a method for removing oil sludge specifically achieved through a single unit for removing oil sludge without damage. Specifically, the single unit for removing oil sludge without damage is fixed on the iron frame structure below the steel wire rope 5 of the tower crane. The self - splicing rotating cylinder 3 is split into two halves. After one half of the self - splicing rotating cylinder 3 is slidably installed in the arc - shaped sliding groove 2 - 2 - 1 along the arc - shaped outer convex retaining edge 3 - 2, the cross - section of the arc - shaped outer convex retaining edge 3 - 2 is upward. Then, the steel wire rope 5 is arranged in the cavity of the self - splicing rotating cylinder 3. Then, the other half of the self - splicing rotating cylinder 3 is installed through bolts 9 to form a complete cylinder body of the self - splicing rotating cylinder 3. Then, the knob member 4 - 1 is rotated, and the knob member 4 - 1 drives the threaded rod 4 - 2 to rotate. The threaded rod 4 - 2 is threadedly connected to the slider 4 - 3.
