Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of hydropower station engineering, and particularly relates to a special steel wire rope cleaning and lubricating device for a hoist of a hydropower station. BACKGROUND

[0002] The hoists used in hydropower stations are mainly divided into two categories: One is the hoist that undertakes the opening and closing and hoisting of metal gates in hydraulic structures. The hoist is divided into a portal hoist, a fixed hoist and a trolley hoist according to different structural forms. Most of the hoists of hydropower stations are located above the ground, and have the characteristics of low working level, low frequency of use, long parking time and the like. Since the steel wire ropes of the hoist are mostly exposed to the air with high humidity for a long time, and some of the steel wire ropes need to work underwater, impurities and dirt in the air and water are easily attached to the surface of the steel wire rope. After the lubricating grease on the surface of the steel wire rope is exposed to light and oxidized for a long time, it is mixed with the surface dirt to form sludge, which greatly shortens the service life of the steel wire rope and increases the safety hazards of the use of the equipment.

[0003] The other is the bridge crane mainly used for the operation and maintenance of water turbine equipment. Some bridge cranes are also used for gate opening and closing, and the working conditions are similar to those of the hoist. The bridge crane is generally located in the underground main plant, and has a relatively high working level and frequency of use. The steel wire rope is in a stressed state for a long time and has a large working load. The metal chips generated by the friction between the steel wires are mixed with the lubricating grease on the surface of the steel wire rope, and under certain conditions, sludge is also generated, which greatly shortens the service life of the steel wire rope and increases the safety hazards of the use of the equipment.

[0004] The current steel wire rope maintenance solutions on the market mainly include: 1. Mobile pressurized oiler: two half-moon cavities are connected by a bolt, and the principle of spring pressurization and the self-weight of two piston pressure devices are used to squeeze and evenly apply corrosion-resistant oil to the steel wire. The device mainly uses human pulling force as the basic power, uses the double ear hinge point above the rope connection device as the basic guide, then uses the spring pressure and counterweight in the double cavity to make the corrosion-resistant oil seep out from the reserved seam at the bottom of the inner wall of the cavity, and finally realizes the sliding of the steel wire rope from bottom to top and the uniform moving of the steel wire rope oiler by the oil output and the pulling speed. The maintenance method has the following main defects: (1) human power is still used as the driving force, which requires a lot of human resources (at least 4 people are needed for one operation); when the length of the steel wire rope of the hoisting equipment is long, the workload of the on-site personnel will increase significantly, and compared with the traditional pure manual oiling, the saved human resources are limited; (2) the pulling force and speed provided by human power are unstable, and the final lubrication effect is poor in stability; (3) it is easily limited by the space layout of the equipment, as the layout design of the hoisting equipment of each hydropower station is different, it can only be applied to equipment that meets certain conditions, and a large number of parts need to be replaced when different specifications of steel wire ropes are encountered, which has poor universality.

[0005] 2. Climbing oiling robot: the climbing robot adopts pneumatic or electric driving form, realizes the function of climbing along the steel wire rope through the cooperation of the control system, transmission system and walking system, and carries out lubrication of the steel wire rope by the contact type oiling equipment. The contact type oiling equipment adopts an oil pump and necessary copper pipes, and uses a contact type brush device to directly engage with the steel wire rope at the pulley; the steel wire rope lubricating grease is distributed by the oil pump → pipeline → brush → steel wire rope surface. The maintenance method has the following main defects: (1) a relatively complex control system is used, which has poor quality stability and is prone to failure, has high maintenance cost, is difficult for on-site personnel to use, and reduces the practicality; (2) the limitation of different equipment space layouts is not considered, and it can only be applied to equipment that meets certain conditions, and a large number of parts need to be replaced when different specifications of steel wire ropes are encountered, which has poor universality; (3) the climbing efficiency on different steel wire rope surfaces cannot be guaranteed, and correspondingly, the oiling efficiency is also affected; (4) the stress mode determines that it can only lubricate the steel wire rope, and cannot clean the surface of the steel wire rope and the waste oil and sludge.

[0031] The application will be further described in connection with specific embodiments, but the application is not limited to these specific embodiments. Those skilled in the art should recognize that the application encompasses all alternatives, modifications and equivalents possible within the scope of the claims.

[0032] Referring to Figures 1-11 The embodiment provides a special steel wire rope cleaning and lubricating device for a hydroelectric station crane, which comprises an oiler 1 fixedly arranged on a steel wire rope 2, the steel wire rope 2 can move relative to the oiler 1, an upper end surface of the oiler 1 is provided with a cleaner 3 capable of rotating relative to the oiler 1, the cleaner 3 is driven to rotate by the steel wire rope 2, an oil collecting device 4 is arranged below the oiler 1, an oil injection cavity 5 is arranged in the oiler 1 for the steel wire rope 2 to pass through, a detachable sealing block 6 is arranged in the middle of the oil injection cavity 5 and capable of dividing the oil injection cavity 5 into an upper cavity and a lower cavity, when the steel wire rope 2 runs at a high speed, the sealing block 6 is removed to connect the two cavities, when the steel wire rope 2 runs at a low speed, the sealing block 6 is arranged, the upper cavity serves as an oil injection cavity and the lower cavity serves as a buffer cavity. The application flexibly adjusts the flow of oil injection by arranging the sealing block 6.

[0033] The oiler 1 comprises an openable and closable oil injection cavity shell 11, a sealing bush 12 is fixedly arranged in the oil injection cavity shell 11, the sealing bush 12 forms the oil injection cavity 5, and the oil injection cavity 5 is provided with an oil inlet hole 51 and an oil outlet hole 52. Specifically, the oil injection cavity shell 11 is opened and closed by a hinge to wrap the steel wire rope 2, and a movable screw and a wing nut are used to clamp and fix the two shell bodies.

[0034] The two ends of the oil injection cavity 5 are provided with replaceable sealing rings 7, which are suitable for steel wire ropes 2 of different sizes and ensure that the oil in the oil injection cavity 5 does not overflow. The inner diameter of the sealing ring 7 is slightly larger than the rope diameter of the steel wire rope 2, which ensures that the steel wire rope 2 can pass through smoothly, but blocks the flowing lubricating oil in the cavity; the outer diameter cooperates with the sealing bush 12 and can be replaced at any time to cooperate with the steel wire rope 2 of different rope diameters.

[0035] The two ends and the inner wall of the middle of the sealing bush 12 are provided with grooves 13 for mounting the sealing ring 7 or the sealing block 6. The inner wall of the sealing bush 12 is provided with a smearing pattern 14 for cooperating with the sealing ring 7 and the sealing block 6 to evenly smear the oil. The smearing pattern 14 is a groove structure.

[0036] The oil injection cavity 5 is connected with an external oil pump station 8 for oil injection. The external oil pump station 8 combines an air compressor with an oil injection pump to inject lubricating oil into the oiler cavity through an oil conveying pipe.

[0037] The oiler 1 is provided with a lifting ring 15, and the oiler 1 is positioned and installed on the steel wire rope 2 through the cooperation of the iron chain 9 and the lifting ring 15. That is, the oiler 1 is stationary, and the steel wire rope 2 moves relative to the oiler 1. The iron chain 9 can be used in various complex environments and has wide application.

[0038] The cleaner 3 is a petal-shaped detachable structure and is locked after being spliced by an external clamp 10. The inner hole of the cleaner 3 is tightly arranged with the outer contour of the steel wire rope 2, so that high-quality cleaning effect is achieved. The cleaner 3 needs to be customized and designed according to different parameters such as the diameter, rotation direction, strand number and twist angle of the steel wire rope 2, so that the cleaner 3 perfectly matches the outer layer of the steel wire rope 2.

[0039] The oil collecting device 4 is connected and fixed to the oiler 1 and hung below the oiler 1. It is a openable and closable structure, the upper end is open, and the bottom is provided with an oil receiving tray. After the steel wire rope 2 exits the oil injection cavity 5, the oil collecting device 4 is used to collect the oil sludge scraped off by the cleaner 3 and the excess oil scraped off by the sealing ring 7 on the outlet side of the oil injection cavity, so as to protect the on-site environment from oil pollution. Specifically, one side of the oil collecting device 4 is connected through a hinge, so that the two parts become a whole, which is convenient for on-site installation, and the other side is provided with a buckle, which is convenient for opening and closing the device; in addition, the circular shape ensures that no damage will be caused when contacting or colliding with surrounding objects; the material Q235B steel is used to ensure the strength of the device. Four holes are arranged on the upper end of the outer wall, and a small-size shackle with the same specification and model as the oil injection cavity is arranged, so as to be connected and fixed to the oil injection cavity through chains or ropes.

[0040] The oiler 1 and the cleaner 3 are modularly provided with multiple sets. The embodiment is provided with two sets of small and large sizes, which can cover all structural types of steel wires 2 with diameters of 14-60 mm, wherein the small size is suitable for steel wires 2 with diameters of 14-31 mm of various structures, and the large size is suitable for steel wires 2 with diameters of 32-60 mm of various structures. The oil injection cavity shell 11 is integrally formed by adopting an aluminum casting process, thereby ensuring the overall strength and sealing performance of the shell and being provided with a handle. The shell is mainly made of aluminum, thereby greatly reducing the weight of the shell. The net weight of the large shell is 3.6 kg, and the net weight of the small shell is only 1.1 kg. Since the personnel of a hydropower station often need to reach the operation area by climbing narrow and high stairs on site, the light weight is more convenient for the personnel to carry. The large size only needs two pairs of opening and closing bolts, and the small size only needs one pair of opening and closing bolts to realize the sealing performance of the device, thereby reducing the operation complexity. Four external threaded holes are arranged, and the number of oil inlet and outlet ports can be freely distributed according to different working conditions. The sealing bush 12 is integrally poured by using synthetic polyester, has moderate material density, is light in weight, and is convenient to carry. In addition, the material will not be corroded by the steel wire cleaning agent (organic solvents such as gasoline and diesel oil). The large and small sizes are also arranged, are highly matched with the oil injection cavity shell 11, and have a smooth appearance without causing scratches. The sealing ring 7 is also integrally poured by using synthetic polyester, has strong wear resistance without causing damage to the outer surface of the steel wire, and will not be corroded by the steel wire cleaning agent (organic solvents such as gasoline and diesel oil). In addition, the diameter of the qualified steel wire is 1.00-1.05 times the nominal diameter of the steel wire. Since the material is elastic, the sealing performance of the steel wire can be ensured for any diameter of the steel wire. The large and small sizes are matched with the sealing bush 12, and the inner diameter is matched with the diameter of the steel wire 2 with an interval of 2 mm. The cleaner 3 is divided into large and small sizes, the opening size is calculated according to the lay length data of the steel wire, is highly matched with the outer contour of the steel wire 2, is designed in three pieces, is convenient to splice, and has strong structural stability. The material uses nylon as the raw material, is light in weight, is wear-resistant, and will not damage the steel wire. The opening is completed by using a five-axis numerical control machine tool, thereby ensuring the precision and ensuring that the outer contour of the steel wire is tightly matched, thereby realizing high-quality cleaning effect. The adjustable high-strength stainless steel clamp is used as a fixing tool (the strength has been verified by calculation), since the diameter of the qualified steel wire is 1.00-1.05 times the nominal diameter of the steel wire, the diameter allowance is adjusted by adjusting the tightness of the fixing clamp. In addition, the three-piece parts are marked with “●”, “●●”, and “●●●” as assembly marks, which are convenient for the operator to match the three-piece parts, thereby realizing rapid assembly.

[0041] The principle of the present application is to fix the oiler 1 and the cleaner 3 on the steel wire rope 2, the oiler 1 is fixed on the steel wire rope 2 by the movable screw and the sheep horn nut; the oiler 1 shell is fixed on a certain section of the steel wire rope 2 by the iron chain 9 and the lifting ring 15, and the self-cleaning is realized by driving the steel wire rope 2 to move by the crane in the empty load operation; the cleaner 3 is fixed on the upstream side of the steel wire rope 2 movement by the hose clamp, and the cleaner 3 is blocked by the oiler 1 to prevent the cleaner 3 from moving with the steel wire rope 2 when the steel wire rope 2 moves. When the crane operates, the steel wire rope 2 moves downward, the cleaner 3 is tightly fixed on the steel wire rope 2 by the hose clamp according to the steel wire rope pattern and the rotation direction, at this time, the inside of the cleaner 3 is rubbed with the steel wire rope, the oil sludge on the outer surface of the steel wire rope 2 and the inside of the rope strand is scraped, and the cleaner 3 rotates relative to the oiler 1 due to the movement of the steel wire rope 2.

[0042] When the present application is used, the specific installation steps are as follows: 1. Install the sealing bush 12: open the opening and closing bolt of the oil injection cavity shell 11, insert the sealing bush 12 into the internal groove of the oil injection cavity shell 11, and ensure that the edge is flat and smooth.

[0043] 2. Set the oiler anti-falling measure: one end of the chain is tied to the lifting lug 15 on one side of the oil injection cavity shell 11, and the other end is tied to a nearby firm steel structure.

[0044] 3. Install the oil injection cavity shell 11 and the oil collection device 4: (a) Tie the fixed chain to the two ends of the oil collection device 4, open the lock buckle, and connect the other end of one of the chains to the fixed buckle on one side of the lower end of the oil injection cavity shell 11; (b) Open the oil injection cavity shell 11 to the maximum amplitude, pass the steel wire rope 2 to make the steel wire rope 2 in the center position of the shell, then close the oil injection cavity shell 11, close the opening and closing bolt and tighten it; (c) Adjust the position of the oil collection device 4 to make the steel wire rope 2 in the center opening, close the lock buckle, and connect the other fixed chain to the fixed buckle on the other side of the lower end of the oil injection cavity shell 11.

[0045] 4. Test the tightening degree of the oil injection cavity shell 11: (a) Hold the shell handle with one hand and pull up and down with force, if the oil injection cavity shell 11 moves up and down along the steel wire rope 2, it means that the shell is installed too loosely and needs to be tightened further; (b) Hold the shell handle with one hand and rotate it counterclockwise or clockwise with force, if the oil injection cavity shell 11 does not rotate around the steel wire rope 2, it means that the shell is installed too tightly and needs to be loosened appropriately.

[0046] 5. Install the cleaner 3: each cleaner 3 is composed of 3 fan-shaped modules, and 3 different marks "●", "●●", "●●●" are printed on both sides of the modules. The same side of the same mark is spliced together to ensure that the inner side of each module of the cleaner 3 is in contact with the outer strand contour of the steel wire rope 2, and after the three modules are in the same plane without misplacement, the fixing clamp is sleeved, and the fixing bolt is tightened with a screwdriver until the three modules are not loose. It is not necessary to tighten the clamp to the tightest.

[0047] 6. Debug the cleaner 3: twist the cleaner 3 with both hands, and rotate and move along the steel wire rope 2 in the upward and downward directions to scrape off the oil sludge near the installation position. After each back and forth, the clamp bolt is tightened by 1 turn, and the operation is repeated 3-5 times until the oil sludge at the installation position of the cleaner 3 is scraped off, and the cleaner 3 is directly in contact with the steel wire rope. After the fixing clamp is tightened, the cleaner 3 can just rotate and move up and down along the surface of the steel wire rope 2.

[0048] 7. Fix the oiler 1: (a) pass one end of the first rope through the upper end of the oil injection cavity shell 11 on one side of the hanger, and tie the other end of the rope to a nearby firm steel structure; another rope is tied to the other side of the firm steel structure in the same way; (b) the direction of the rope is inclined, and the contact of the sharp and useful edge angle and the steel wire rope 2 is avoided; (c) after confirming the firmness of the rope, the anti-falling chain of the oiler 1 can be removed.

[0049] 8. Place the installation air compressor and oil injection pump: (a) connect the air compressor to the 220V power supply, and connect the other end of the air pipe to the oil injection pump. Turn on the power and inflate; (b) insert the oil extraction pipe of the oil injection pump into the lubricating grease, and connect one end of the oil injection pipe; (c) connect the other end of the oil injection pipe to the oil injection cavity shell 11. The part of the oil injection pipe connected to the oil injection cavity shell 11 is a transparent flexible pipe, which can observe the state of the oil entering the oil injection cavity shell 11.

[0050] The specific operation steps of the present application are as follows: (a) start the lifting mechanism, and use multiple 1 gear point lifting operations until one fixed rope is tensioned; (b) continue to point down until the cleaner 3 is in close contact with the oil injection cavity shell 11. Observe whether the cleaner clamp is intact, whether the cleaner module is misaligned, and whether the cleaner rotates smoothly along the steel wire rope; (c) after confirming that the cleaner can operate normally, remove the heavy clamp outside the cleaner, and start the air compressor to drive the oil injection pump; (d) Observe the transparent oil injection hose, and after the transparent oil injection hose is filled with grease, the lifting mechanism is sequentially raised at 1st, 2nd and 3rd speed continuously, each speed is kept for 10 seconds, and then stopped; (e) Another bucket of lubricating grease (regular lithium-based grease) is replaced, and steps (c) and (d) are repeated; (f) After the above steps are completed, the lifting mechanism stops running, and all the oiling device components are removed in sequence; (g) The lifting mechanism is operated at 1st speed in the descending mode, and the oiling and cleaning of the steel wire rope are observed and recorded; (h) Test end: stop running the equipment, and all the oiling device components are assembled into the tool bag in sequence, and the operation area is cleaned.

[0051] When the present application is used, the ambient temperature is 25-30°C, the oiling standard is A-4, and the oiling is uniform and without leakage; the matching relationship between the lifting mechanism speed and the oiling device oil feeding speed is as follows: (1) Lifting speed (portal crane, fixed winding): 1st speed, air inlet pressure: 0.4-0.6 MPa (2) Lifting speed (bridge crane): 1st speed, air inlet pressure: 0.3-0.4 MPa (3) Lifting speed (bridge crane): 2nd speed, air inlet pressure: 0.6-0.8 MPa.

[0052] The present application has simple structure and convenient operation, and after installation and adjustment, only relies on the movement of the steel wire rope itself for cleaning and lubricating greasing, without manual intervention, thereby enhancing the reliability, greatly reducing the labor intensity and safety hazards, and enabling the cleaning and greasing to reach the core of the rope and the core of the rope, thereby realizing the deep maintenance of the steel wire rope. The miniaturization and modular design break through the limitation of the layout space of the hoisting equipment, enable the steel wire rope cleaning and lubricating device to be installed and run on hoisting equipment with different layout forms, and simultaneously reduce the installation and operation difficulty. The present application has the integrated functions of cleaning, oiling and collecting.
