Description
Technical Field
[0001] This invention belongs to the field of crane technology, specifically relating to an anti-twist device for wire ropes of hydropower station cranes. Background Technology
[0002] In the field of hydropower engineering, hydropower station cranes are core operating equipment, undertaking key tasks such as opening and closing gates, hoisting core components of generator units, and transferring heavy maintenance tools. Their operational stability and reliability directly determine the continuous power generation capacity, unit maintenance efficiency, and overall operational safety of the hydropower station.
[0003] Especially during the installation and overhaul of generator sets, cranes need to precisely lift heavy core components such as rotors and stators, requiring extremely high operational precision and safety. As the core force transmission and load-bearing element of the crane, the wire rope is the key carrier for realizing power transmission and operation execution. By winding, coiling or releasing the wire rope on the wire rope column, the lifting, translating and other actions of heavy objects can be completed. Its operating status directly affects the operational precision and safety performance of the crane. With the continuous increase in the single-unit capacity of hydropower stations, the rated lifting capacity and operating load of cranes are constantly increasing, placing higher demands on the stability and safety of wire rope winding and unwinding mechanisms. Currently, the existing wire rope winding and unwinding mechanisms of hydropower station cranes mainly use a drive motor to rotate the wire rope column around its own axis to achieve the winding and coiling of the wire rope (lifting heavy objects) or the release and unwinding (lowering heavy objects). To avoid problems such as winding disorder and accelerated wear caused by lateral displacement during the wire rope winding and unwinding process, some mechanisms will fix one or more support plates inside the support frame. The support plates form lateral obstructions to the wire rope, limiting the lateral displacement range of the wire rope and attempting to ensure the orderly winding and unwinding of the wire rope. However, in actual operation, the design of the fixed support plate of the existing wire rope winding mechanism has obvious technical defects and is difficult to meet the needs of complex operation scenarios: On the one hand, the support plate is a fixed structure and cannot be adaptively adjusted according to the changes in the winding position of the wire rope on the wire rope post. As the number of winding layers of the wire rope on the wire rope post increases or the winding position moves axially during release, the relative position between the fixed support plate and the wire rope will gradually deviate, resulting in a weakening of the lateral blocking effect. It may even cause hard friction between the support plate and the wire rope due to the fixed position, which will aggravate the wear of the wire rope. On the other hand, during the lifting of heavy objects, the tension of the wire rope will fluctuate dynamically due to factors such as the shift of the center of gravity of the heavy object, wind speed disturbance, and changes in lifting speed. This can easily cause the wire rope to shift laterally or twist. The fixed support plate lacks the ability to dynamically correct the direction of the wire rope and cannot adjust the blocking position and force in real time, making it difficult to effectively suppress the shifting and twisting trend of the wire rope. The aforementioned technical defects will cause a series of serious problems: First, disordered wire rope winding and unwinding will lead to overlapping or biting of the wire rope on the wire rope post, aggravating local wear and fatigue damage, significantly shortening the service life of the wire rope, and increasing equipment maintenance costs and replacement frequency; Second, lateral deviation and torsion of the wire rope will cause swaying and swinging during the hoisting of heavy objects, reducing the accuracy of the operation. Especially when hoisting core components of the generator set, the swinging collision may cause damage to the components, resulting in significant economic losses; More seriously, if the strength of the wire rope decreases due to wear or torsion, there may be a risk of rope breakage, which may lead to safety accidents such as the falling of heavy objects, threatening the lives of on-site workers and the safety of hydropower station equipment. Summary of the Invention
[0004] This invention provides an anti-twist device for wire ropes of hydropower station cranes, which addresses the technical deficiency of existing technologies that cannot dynamically correct the direction of the wire rope based on operational requirements such as changes in the winding position of the wire rope on the wire rope post and tension fluctuations during heavy lifting. To achieve the above objectives, the present invention employs the following technical solution: A wire rope anti-twist device for a hydropower station crane, comprising: The support frame is a structure with one end open and the other end closed.

The assembly block has an installation port that cooperates with the wire rope.
[0005] Furthermore, the second limiting component includes: Sliding block two is connected to sliding block one and slidably connected inside the support frame, wherein the support frame is provided with a slot one; A fixed column is fixedly mounted on the second sliding block and slidably connected to the assembly block; The assembly block has a rectangular structure, and the mounting opening is located on the assembly block between the threaded rod and the fixing post.
[0006] Furthermore, the cross-section of the mounting port is annular.
[0007] Furthermore, a support plate is provided between the two opposite sides of the open end of the support frame, and a movable groove is provided on the support plate; The assembly block is connected to a support rod at the end away from the motor. The end of the support rod extends into the movable groove and is connected to a mounting plate and a lubrication assembly. The mounting plate is located above the movable groove, and the lubrication assembly is located below the movable groove and above the wire rope column. The lubrication component is used to lubricate the wire rope on the wire rope post.
[0008] Furthermore, the movable groove is formed along the entire length of the support plate; The lubrication assembly includes: A baffle plate is fixed on a support rod, and an oil-draining port is provided inside the baffle plate; A limiting plate and a filter plate are disposed on the baffle, with the filter plate passing through the grease vent.
[0009] Furthermore, the support rod has a T-shaped structure, and a baffle is provided on the vertical end of the support rod.
[0010] Furthermore, an upper plate is slidably connected in the groove, and the motor is fixed to the upper plate; The bottom of the motor is fixedly provided with a lower plate, which is slidably connected to the support frame. The support frame has a slot 2 inside. The lower surface of the lower plate is connected to a fixing component.
[0011] Furthermore, the fixing component one includes: A connecting plate 1 has its upper surface fixedly connected to the lower surface of the lower plate. A connecting plate 2 is fixedly connected to the outside of the connecting plate 1, and a sliding column is slidably connected inside the connecting plate 2. A rubber head is fixedly connected to the top of the sliding column, and the outside of the rubber head is snapped into the inside of the second slot. A handle is fixedly connected to the bottom of the sliding column.
[0012] Furthermore, a fixing component two is provided on the outside of the sliding block two, the fixing component two including: The card plate is externally slidably connected to the sliding block 2, and the sliding block 2 is fixedly connected to the inside of the card slot 1 by the fixing component 2; The sliding block 2 is fixedly connected to the outside of the mounting plate 2, and a support column is fixedly connected to the lower surface of the mounting plate 2.

The bottom end of the support column is located on the upper surface of the card plate, the outside of the support column penetrates the card plate, and the inside of the card plate is provided with a limit component.
[0013] Furthermore, the limiting component one includes: A flip plate is externally rotatably connected to the inside of a mounting plate. One end of the flip plate is provided with a second spring, and the other end of the second spring is provided on the upper surface of the mounting plate. A locking tooth is fixedly connected to the outside of the flip plate, and the locking tooth engages with the upper surface of the mounting plate.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The assembly block of the anti-torsion component has an installation port that mates with the wire rope. This installation port can form a wrapping constraint on the wire rope, which can more comprehensively restrict the lateral displacement of the wire rope compared to the one-sided obstruction of the traditional support plate. When the wire rope tends to shift laterally or twist due to the shift of the center of gravity, wind speed disturbance or changes in lifting speed during the hoisting of heavy objects, the inner wall of the installation port can apply a uniform lateral corrective force to the wire rope, suppress the shift and twist in real time, and prevent the wire rope from becoming disordered and tangled.
[0015] 2. The sliding block 2 of the limiting component 2 is connected to the sliding block 1 and is slidably connected in the slot 1 inside the support frame. The cooperation of the sliding block 1, the sliding block 2 and the slot 1 forms a first-level limiting system. At the same time, the fixed column is fixed on the sliding block 2 and slidably connected to the assembly block. The cooperation of the fixed column and the assembly block forms a second-level limiting system, realizing the function of dual limiting and improving the stability of the assembly block movement process.
[0016] 3. The inner ring of the annular mounting opening fits perfectly with the circular cross-section of the wire rope, thus providing full-circumference restraint to the wire rope.
[0017] 4. The lubrication component is connected to the assembly block via a support rod. The assembly block can move dynamically along the threaded rod according to the winding position of the wire rope, so that the lubrication component can move synchronously with the winding and unwinding trajectory of the wire rope. When the wire rope is wound from one end to the other on the wire rope post, the assembly block drives the support rod to slide smoothly along the movable groove, thereby ensuring that the lubrication component is always precisely aligned with the wire rope at the current winding position for lubrication.
[0018] 5. The movable groove is opened along the entire length of the support plate, which can cover the entire axial range of the wire rope column. It allows the support rod to drive the lubrication component to move along the entire length of the support plate. No matter whether the wire rope is at the leftmost or rightmost winding position on the wire rope column, the lubrication component can slide smoothly along the entire axial range of the wire rope through the support rod, so as to achieve lubrication coverage of the entire axial range of the wire rope.
[0019] 6. The overall rigidity of the T-shaped structure ensures that the support rod maintains a straight line motion as it slides along the movable groove, preventing the lubrication components from shifting due to rod deformation and ensuring the accuracy of lubricant application.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0027] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
[0029] To address the technical deficiencies mentioned in the background section, this invention provides an anti-twist device for wire ropes of hydropower station cranes. The invention will now be described in further detail with reference to the accompanying drawings: like Figures 1-8 As shown, a wire rope anti-twist device for a hydropower station crane includes a support frame 1, which is an open-end and closed-end structure; a mounting frame 2, fixed to the outside of the open end of the support frame 1, with a motor 3 installed on the side of the mounting frame 2 near the open end; a wire rope post 4, rotatably connected to the open end of the support frame 1, the wire rope post 4 being connected to the drive end of the motor 3 via a belt, and a wire rope wound around the outside of the wire rope post 4; a slide 6, opened on one side of the open end of the support frame 1 and located below the wire rope post 4; and a motor 8, disposed in the slide 6, with the drive end of the motor 8 connected to... There is a threaded rod 10, and a sliding block 11 is rotatably connected to the end of the threaded rod 10. The sliding block 11 is slidably connected to the support frame 1. A limiting component 2 is set outside the sliding block 11. An anti-torsion component 15 is slidably connected to the outside of the limiting component 2 at one end and screwed to the threaded rod 10 at the other end. The anti-torsion component 15 includes an assembly block 151. One end of the assembly block 151 is screwed to the outside of the threaded rod 10 and the other end is slidably connected to the limiting component 2. An installation port 152 is opened on the assembly block 151 and the installation port 152 cooperates with the wire rope.
[0030] In the above structure, the synergistic action of motor 8, threaded rod 10, sliding block 11, and anti-torsion component 15 overcomes the limitation of traditional fixed support plates being unable to be adjusted. After the wire rope is wound on the wire rope post 4 and connected to the equipment to be lifted or lowered, when the position of the wire rope wound on the wire rope post 4 moves axially, motor 8 can drive the threaded rod 10 to rotate. Since the assembly block 151 of the anti-torsion component 15 is screwed to the threaded rod 10 and its other end is slidably connected to the limiting component 2, the rotation of the threaded rod 10 is converted into a smooth movement of the assembly block 151 along the axial direction of the threaded rod 10, thereby driving the mounting port 152 on the assembly block 151 to move and adjust the position of the wire rope. For example, when the wire rope shows a lateral deviation or torsion tendency due to the shift of the center of gravity, wind speed disturbance, or change in lifting speed during the lifting of heavy objects, the inner wall of the mounting port 152 can apply a uniform lateral corrective force to the wire rope, suppressing the deviation and torsion in real time and preventing the wire rope from becoming disordered and entangled.
[0031] Meanwhile, if the wire rope deviates to one side, the motor 8 can drive the assembly block 151 to move in the corresponding direction. Through the active correction of the mounting port 152, the wire rope is pulled back to the preset track, which can effectively prevent the wire rope from overlapping or biting, greatly reduce local wear and fatigue damage of the wire rope, and extend its service life.
[0032] Furthermore, the limiting component two includes a sliding block two 13, which is connected to the sliding block one 11 and slidably connected inside the support frame 1. The support frame 1 has a slot one 12. A fixing post 14 is fixed on the sliding block two 13 and slidably connected to the assembly block 151. The assembly block 151 has a rectangular structure, and an installation port 152 is opened on the assembly block 151 and located between the threaded rod 10 and the fixing post 14. The cross-section of the installation port 152 is annular.
[0033] The assembly block 151 adopts a rectangular structure, and the mounting port 152 is opened between the threaded rod 10 and the fixed post 14, which can maximize the wrapping constraint effect of the mounting port 152 on the wire rope. In application, the rectangular structure provides the assembly block 151 with a stable force support surface, avoiding stress concentration in circular or irregular structures under force. The mounting port 152 is located between the threaded rod 10 and the fixed post 14, so that the two sides of the mounting port 152 are respectively driven by the threaded rod 10 and slidably constrained by the fixed post 14, ensuring that the mounting port 152 maintains a stable shape and position during the correction process and will not deform or shift due to force. In addition, when the wire rope shifts to the threaded rod 10 side, the inner wall of the mounting port 152 near the threaded rod 10 side will first apply a corrective force; when it shifts to the fixed column 14 side, the inner wall near the fixed column 14 side will respond quickly, forming a bidirectional balanced correction, avoiding insufficient correction force on one side due to the position shift of the mounting port 152, and further improving the comprehensiveness and reliability of anti-torsion correction.
[0034] like Figure 3 and Figure 4 As shown, a support plate 5 is provided between the two opposite sides of the open end of the support frame 1, and a movable groove is provided on the support plate 5; the end of the assembly block 151 away from the motor 3 is connected to a support rod 16, and the end of the support rod 16 extends into the movable groove and is connected to an mounting plate 17 and a lubrication component 18. The mounting plate 17 is located above the movable groove, and the lubrication component 18 is located below the movable groove and above the wire rope column 4; wherein, the lubrication component 18 is used to lubricate the wire rope on the wire rope column 4.
[0035] On the one hand, the lubrication component 18 is connected to the assembly block 151 via the support rod 16, and the assembly block 151 can move dynamically along the threaded rod 10 according to the winding position of the wire rope, so that the lubrication component 18 can move synchronously with the winding and unwinding trajectory of the wire rope; when the wire rope is wound from one end to the other on the wire rope post 4, the assembly block 151 drives the support rod 16 to slide smoothly along the movable groove, thereby ensuring that the lubrication component 18 is always precisely aligned with the wire rope at the current winding position.
[0036] On the other hand, when the wire rope column 4 rotates to wind and unwind the wire rope, the lubrication component 18 covers the wire rope at different positions on the wire rope column 4 as the anti-twist component 15 moves. Through continuous lubrication, the frictional loss between the wire rope and the wire rope column 4 and the anti-twist component 15 is reduced, the service life of the wire rope is extended, and the maintenance frequency and cost of the device are reduced.
[0037] In this plan, such as Figure 3 and Figure 4 As shown, the movable groove is opened along the entire length of the support plate 5. The lubrication assembly 18 includes a baffle 181, which is fixed on the support rod 16. An oil vent 182 is opened inside the baffle 181. A limiting plate 183 and a filter plate 184 are disposed on the baffle 181, and the filter plate 184 passes through the oil vent 182. The support rod 16 has a T-shaped structure. One end of the horizontal end of the support rod 16 is connected to the assembly block 151, and the other end is connected to the mounting plate 17. The baffle 181 is disposed on the vertical end of the support rod 16.
[0038] An upper plate 7 is slidably connected in the slide groove 6. A motor 8 is fixed on the upper plate 7. A lower plate 9 is fixed at the bottom of the motor 8. The lower plate 9 is slidably connected in the support frame 1. A second slot 21 is opened inside the support frame 1. A fixing component 19 is connected to the lower surface of the lower plate 9. The fixing component 19 includes a connecting plate 191. The upper surface of the connecting plate 191 is fixedly connected to the lower surface of the lower plate 9. A second connecting plate 192 is fixedly connected to the outside of the connecting plate 191. A sliding column 193 is slidably connected inside the connecting plate 192. A rubber head 195 is fixedly connected to the top of the sliding column 193. The outside of the rubber head 195 is engaged inside the second slot 21. A handle 194 is fixedly connected to the bottom of the sliding column 193.
[0039] During assembly, the operator first aligns the lower plate 9 with the installation position inside the lower side of the support frame 1, aligning the connecting plate 191 and connecting plate 192 fixed on the lower surface of the lower plate 9 with the slot 21. Then, the operator holds the handle 194 and pushes the sliding column 193 upward until the rubber head 195 at the top of the sliding column 193 is fully engaged in the slot 21. At this point, the rubber head 195 uses its own elasticity to fit tightly against the inner wall of the slot 21, forming a stable engagement. The lower plate 9 and the support frame 1 are then fixed together by the connecting plate 191 and connecting plate 192. When it is necessary to disassemble or adjust the motor 8, simply pull the handle 194 downward, causing the sliding column 193 to slide downward along the connecting plate 192, so that the rubber head 195 disengages from the slot 21. This releases the fixed relationship between the lower plate 9 and the support frame 1, allowing the lower plate 9 and the motor 8 to be removed from the support frame 1.
[0040] In this design, a fixing component 20 is provided on the outside of the sliding block 13. The fixing component 20 includes a locking plate 201, which is slidably connected to the outside of the sliding block 13. The sliding block 13 is fixedly connected to the inside of the slot 12 through the fixing component 20. A mounting plate 203 is fixedly connected to the outside of the sliding block 13. A support column 204 is fixedly connected to the lower surface of the mounting plate 203. A spring 202 is provided on the outside of the support column 204. The top end of the spring 202 is located on the lower surface of the mounting plate 203. The bottom end of the support column 204 is located on the upper surface of the locking plate 201. The outside of the support column 204 penetrates the locking plate 201. A limit component 205 is provided inside the locking plate 201.
[0041] The limiting component 205 includes a flip plate 2051, which is externally rotatably connected to the inside of the clamping plate 201. A spring 2052 is provided at one end of the flip plate 2051, and the other end of the spring 2052 is located on the upper surface of the clamping plate 201. A locking tooth 2053 is fixedly connected to the outside of the flip plate 2051, engaging with the upper surface of the mounting plate 203. When it is necessary to fix the sliding block 13, the operator releases the clamping plate 201, which slides downwards along the axis of the support column 204. As the clamping plate 201 moves downwards, its bottom gradually embeds into the slot 12 of the support frame 1.
[0042] When it is necessary to disassemble the sliding block 213, the operator lifts the pressure plate 201. The pressure plate 201 will slide upward along the outside of the support column 204. During this process, the spring 1 202 is compressed and generates an upward restoring force. As the pressure plate 201 moves upward, the flip plate 2051 inside the pressure plate 201 will be squeezed by the lower surface of the mounting plate 2203 and flip around its own rotation axis. The locking teeth 2053 outside the flip plate 2051 will be locked onto the upper surface of the mounting plate 2203 under the elastic force of the spring 22052, forming a lock.
[0043] In practical application, the wire rope is first installed in the mounting port 152. When the motor 3 drives the wire rope column 4 to rotate via the belt, the wire rope column 4 rotates around its own axis, thereby realizing the wire rope winding and unwinding operation. When the wire rope column 4 rotates, the motor 8 is started simultaneously. The motor 8 drives the threaded rod 10 to rotate. The threaded rod 10 is inside the sliding block 11. When the threaded rod 10 rotates, it drives the anti-torsion component 15 to move simultaneously. When the threaded rod 10 rotates, the anti-torsion component 15 moves smoothly along the axis of the fixed column 14. During this process, when the anti-torsion component 15 moves, it drives the support rod 16 and the mounting plate 17 to move. The mounting plate 17 will slide and connect... Attached to the upper surface of the support plate 5, when the support rod 16 moves, it will drive the lubrication assembly 18 to move synchronously. The baffle 181 of the lubrication assembly 18 is set outside the wire rope column 4. When excess lubricating oil of the wire rope passes through the baffle 181, the oil drain 182 will collect the lubricating oil under the action of the limiting plate 183. The collected lubricating oil will be redistributed to the wire rope through the oil outlet of the oil drain 182. At the same time, the filter plate 184 set in the middle of the baffle 181 filters the lubricating oil, removes impurities, and prevents impurities from adhering to the surface of the wire rope with the lubricating oil, ensuring that the lubricating oil is evenly and cleanly applied to the wire rope, reducing the wear of the wire rope. The baffle 181 can also correct the travel path of the wire rope.
[0044] In addition, when the support rod 16 moves along the axis of the wire rope column 4 with the anti-torsion component 15, the baffle 181 will move synchronously against the wire rope outside the wire rope column 4. During the wire rope winding and unwinding process, excess lubricating oil on the surface of the wire rope will be blocked by contact with the baffle 181. At this time, the limiting plate 183 on one side of the baffle 181 will form a barrier for the lubricating oil to prevent the lubricating oil from dripping and causing waste. The blocked lubricating oil will flow along the oil vent 182 inside the baffle 181. The filter plate 184 passing through the oil vent 182 will filter the flowing lubricating oil and intercept impurities such as metal shavings and dust mixed in it. The filtered clean lubricating oil will flow back to the surface of the wire rope through the oil outlet of the oil vent 182 to realize the recycling of lubricating oil.
[0045] When the position of the anti-torsion component 15 needs to be adjusted, pull the locking plate 201. The locking plate 201 will slide outside the sliding block 13. When the locking plate 201 slides, the spring 202 is compressed, and the support column 204 passes through the locking plate 201 and slides inside the locking plate 201. At the same time, the flip plate 2051 is rotated by the pressure of the mounting plate 203, and the spring 2052 is stretched. When the locking teeth 2053 fixed outside the flip plate 2051 are engaged with the upper surface of the mounting plate 203, the spring 2052 is reset, further locking the position of the locking plate 201, ensuring that the sliding block 13 is stably fixed inside the slot 12, thereby ensuring that the position of the anti-torsion component 15 is fixed.
[0046] The operator pulls the handle 194, causing the sliding column 193 to slide inside the connecting plate 192, aligning the rubber head 195 with the slot 21 opened inside the lower side of the support frame 1, and then releases the handle 194. The rubber head 195 is then engaged inside the slot 21, thus fixing the lower plate 9 to the support frame 1.
[0047] When it is necessary to disassemble or repair the anti-torsion component 15 and the motor 8, pull the clamping plate 201. The clamping plate 201 will slide outside the sliding block 2 13. When the clamping plate 201 slides, the spring 1 202 is compressed, and the support column 204 passes through the clamping plate 201 and slides inside the clamping plate 201. At the same time, the flipping plate 2051 is squeezed by the mounting plate 2 203 and rotates. The spring 2 2052 is stretched. When the clamping teeth 2053 fixed outside the flipping plate 2051 are engaged with the upper surface of the mounting plate 2 203, the spring 2 2052 resets and further locks the position of the clamping plate 201, ensuring that the sliding block 2 13 is stably fixed inside the slot 1 12, thereby ensuring that the anti-torsion component 15 is fixed in position. Pull the handle 194 to drive the sliding column 193 to slide inside the connecting plate 2 192, so that the rubber head 195 leaves the slot 2 21. Finally, the anti-torsion component 15 and the motor 8 can be taken out.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
