Description

Technical Field

[0001] This utility model relates to the field of relay device technology, and in particular to a relay device rod vibration device. Background Technology

[0002] In the operation and maintenance of water turbines or other hydraulic machinery, the relay plays a crucial role. As the core actuator, its performance directly affects the stability and reliability of the entire equipment. As a key component for transmitting hydraulic power, the relay rod inevitably experiences wear and deformation during long-term operation. Therefore, to ensure the normal operation of the equipment, these components need to be regularly disassembled and overhauled to carefully inspect for wear and deformation, and seals need to be replaced to prevent hydraulic oil leakage. In traditional maintenance procedures, compressed air is typically injected into the cylinder of the relay, using the air pressure to blow the relay rod out of the cylinder.

[0003] However, this method has some technical drawbacks and shortcomings. Long-term friction, corrosion, or accumulation of impurities between the relay rod and the cylinder can cause jamming at their mating surfaces. In this case, the thrust provided by compressed air alone is often insufficient, preventing the rod from being smoothly expelled from the cylinder. Therefore, maintenance personnel must resort to external mechanical force, such as hammering or lifting, to help the rod dislodge. However, this method can easily lead to damage or even deformation of the rod's surface. Furthermore, because the relay rod typically has a slender structure, and in some models, one end of the rod is connected to a heavy component, such as a piston head, its center of gravity gradually shifts outward when it is pushed out by air pressure. This can cause the rod to suddenly tilt or slip. In this situation, not only could the rod's end threads or sealing surfaces be damaged by impact with the ground, but the cylinder could also tip over due to instantaneous imbalance, posing a threat to operational safety. Existing maintenance methods lack real-time support and guidance for the movement of the pole, which requires multiple maintenance personnel to work together to straighten the pole. This not only increases labor costs, but also poses a significant operational risk because it is difficult to accurately control the movement trajectory of the pole when multiple people are operating.

[0004] The patent "A Horizontal Irregularly Shaped Pole Head Repair Fixture for Relay Vehicles" (authorization announcement number CN220051448U, hereinafter referred to as Prior Art 1) discloses that, according to the patent specification, the main technical principle of this patent is to monitor the weight of each lifting point in real time using four electronic crane scales and to finely adjust it using a hand-operated hoist to prevent the threads of the relay vehicle pole head from becoming constricted during operation, thus preventing the threads from sticking. At the same time, the overall suspension and disassembly method, compared to the lower rigid support method, makes the pole head less prone to constriction and the threads less prone to sticking due to the flexibility of the hand-operated hoist and slings; it also reduces the requirement for concentricity between the rounding mechanism and the pole head, thus reducing the difficulty of the operation. However, Prior Art 1 cannot provide real-time support during the movement of the pole body during repair, resulting in instability and safety risks during the removal of the pole body. Utility Model Content

[0005] In view of this, the present invention provides a relay rod vibration device to solve the problem that in the prior art, it is difficult to provide real-time support for the movement process of the rod during maintenance, which leads to instability and safety risks in the rod during the removal process.

[0016] The relay rod vibration device provided by this utility model has the following beneficial effects:

[0017] This utility model provides a relay rod vibration device that significantly improves the safety and efficiency of the maintenance process through a synchronously movable support mechanism and an adaptive adjustment structure.

[0037] Example 1

[0038] Please see Figure 1 This utility model provides a relay rod vibration device. During the disassembly of the relay rod 110, several challenging problems are frequently encountered, such as jamming, making it difficult to remove smoothly or causing significant difficulty in disassembly. These problems are mainly caused by various factors, including but not limited to corrosion of the relay rod 110, sludge deposition, aging and adhesion of seals, and minor deformation of mating surfaces. Traditional disassembly methods typically rely on compressed air to blow out the relay rod 110, but this method often fails to effectively remove the relay rod 110 due to insufficient thrust or excessive frictional resistance. To address these issues, this utility model proposes an innovative relay rod vibration device, aiming to achieve disassembly of the relay rod 110 in a more efficient and reliable manner.

[0039] Please see Figure 1In this embodiment, the relay rod 110 vibration device includes a blowing mechanism 200 and a workbench 310 for placing the relay 100. The workbench 310 is provided with a base plate 311 and a side plate 312 perpendicular to the base plate 311. The base plate 311 is provided with a clamp 400 for fixing the relay 100. The side plate 312 is provided with a vibration mechanism 500 that can move towards or away from the clamp 400 based on the side plate 312. The vibration mechanism 500 is inclined to the side plate 312. After the vibration mechanism 500 moves towards the base plate 311, the vibration head 523 of the vibration mechanism 500 abuts against the relay 100 held on the clamp 400. The blowing mechanism 200 is arranged adjacent to the side plate 312 and can pass through the side plate 312 to blow air onto the relay 100.

[0040] When using, please refer to Figure 1 By activating the blowing mechanism 200 to blow air onto the relay 100 mounted on the clamp 400, and simultaneously activating the vibration mechanism 500, the vibration mechanism 500 moves towards the base plate 311, and its vibration head 523 comes into contact with the relay 100 held on the clamp 400. Through the vibration of the vibration mechanism 500, the frictional resistance between the relay rod 110 and the surrounding components is effectively reduced, and in conjunction with the blowing force of the blowing mechanism 200, a combined force is formed, thereby enabling the relay rod 110 to be vibrated out of the device more smoothly.

[0041] Please see Figure 1 and Figure 2 In this embodiment, the synergistic effect of the vibration mechanism 500 and the air pressure blowing mechanism 200 can effectively solve the problem of jamming caused by rust, impurities or aging of seals on the relay rod 110.

[0042] The vibration mechanism 500 employs micro-amplitude vibrations at different frequencies in conjunction with an inclined installation design. This allows for both axial loosening of the rod and shear force to break down the corrosion layer on the mating surfaces. Simultaneously, the vibration assistance significantly reduces air pressure requirements, enabling the rod to be removed smoothly without damaging the mating surfaces. Compared to traditional methods involving pure air pressure or manual tapping, this solution, through controllable vibration parameters (adjustable frequency and amplitude) and a flexible contact design, ensures a high success rate in removal while avoiding the risk of rod deformation or damage to the sealing surfaces.

[0043] Further, please see Figure 1The clamp 400 includes a mounting groove 410 adapted to the relay 100, and a first limiting rod 421 and a second limiting rod 422 disposed on both sides of the mounting groove 410. In use, the first limiting rod 421 and the second limiting rod 422 effectively limit the movement range of the relay 100 within the mounting groove 410, preventing it from shifting or falling during blowing and vibration. The design of the first limiting rod 421 and the second limiting rod 422 fully considers the shape and size of the relay 100, ensuring that the relay 100 can be securely clamped within the mounting groove 410.

[0044] Furthermore, sliding guide rails 511 are provided on the side plates 312 on both sides of the mounting groove 410; the vibration mechanism 500 is connected to the sliding guide rails 511 via sliders 512 and moves based on the sliding guide rails 511. This design allows the vibration mechanism 500 to move closer to or further away from the relay 100, thereby flexibly adjusting the point of application and intensity of the vibration, ensuring that the vibration effect is precisely applied to the joint surface between the relay 100 and the rod. The introduction of the sliding guide rails 511 not only improves the convenience of operation but also enhances the stability of the vibration mechanism 500 during operation, reducing additional vibration or displacement caused by vibration, and further improving the accuracy and safety of assembly and disassembly. In addition, the design of the sliding guide rails 511 facilitates maintenance and replacement, extending the service life of the overall equipment.

[0045] Furthermore, the vibration mechanism 500 includes a mounting frame 521 and a vibration motor 522 disposed on the mounting frame 521; a vibration head 523 is provided on the output shaft of the vibration motor 522; the vibration motor 522 is installed at a predetermined angle to the mounting frame 521.

[0046] The vibration motor 522 of the vibration mechanism 500 acts on the cylinder of the relay 100 with high-frequency (e.g., 50-200Hz) and small amplitude (0.1-2mm) vibration, causing high-frequency micro-slippage between the rod and the cylinder mating surface, breaking down the adhesion layer formed by rust or sludge. The vibration energy is transferred to the contact surface, effectively overcoming static friction and allowing the rod to change from a "locked" state to a "movable" state. At this time, the blowing mechanism 200 (compressed air) provides continuous axial thrust, while the vibration mechanism 500 further weakens the local bonding force between the rod and the cylinder through high-frequency impact, forming a composite disassembly mode of "vibration + air pressure".

[0047] Traditional hammering methods can easily lead to deformation of the rod end or damage to the threads, while vibration gradually loosens the rod through the energy accumulation effect, reducing the risk of impact from instantaneous large loads on the equipment.

[0048] The vibrating head 523 is made of polyurethane (PU) or engineering plastics (such as nylon or POM). These materials have a moderate modulus of elasticity, which can absorb some of the vibration energy and avoid damage caused by hard contact between metals. They have good wear resistance (especially after adding wear-resistant fillers), do not stick to metal surfaces, and are insulating and rust-proof, making them suitable for humid or oily environments.

[0049] Furthermore, in the vibrating device of the relay rod 110, the vibration mechanism 500 is installed at an angle; typically at an angle of 15° to 45° with the horizontal plane. Compared with vertical or horizontal installation, the vibration energy is more concentrated in the dismantling direction, improving the success rate.

[0050] The inclined installation of the vibrating head 523 decomposes the vibration energy into two components: axial (removal direction) and radial (pressing direction), forming a combined effect. The axial component directly assists the removal movement of the relay rod 110, reducing air pressure requirements. The radial component ensures that the vibrating head 523 is always in close contact with the end face of the relay 100, avoiding poor contact due to vibration rebound.

[0051] If the vibrating head 523 is installed axially (horizontally), the vibration energy will be converted into axial impact, which may cause the relay rod 110 to vibrate instantaneously, potentially damaging the sealing surface or threads.

[0052] When installed at an angle, the radial force can partially absorb vibration and impact, forming a gentle disassembly process of "pressing-vibration-pushing out," which reduces the risk of the rod suddenly popping out and improves operational safety.

[0053] Example 2

[0054] Please see Figure 1 and Figure 4 This utility model provides a support mechanism 600 for a relay rod vibration device. During the disassembly of the relay rod 110, the rod is prone to center of gravity shift, tilting, or even slipping due to uneven weight distribution (e.g., the piston end is heavier) or increased extension length. This could cause the rod end to hit the ground, damaging the threads, sealing surface, or guide section; the cylinder may also tilt due to unbalanced force, threatening the safety of operators; and multiple people are needed to manually right it, which is inefficient and poses a risk of pinching injuries. Therefore, the support mechanism 600 provided in this utility model can provide stable support and effectively prevent the rod from slipping or hitting the ground.

[0055] In this embodiment, the support mechanism 600 is disposed on one side of the workbench 310 and is used to support the vibrated relay rod 110.

[0056] Please see Figure 5The supporting mechanism 600 includes at least a first supporting part 610 and a second supporting part; the first supporting part 610 provides initial support, receiving the end of the relay rod 110; it provides support when the rod initially extends, preventing initial tilting. The second supporting part moves gradually as the rod extends, forming a segmented support to avoid bending due to excessively long suspended sections.

[0057] Furthermore, depending on the length of the relay rod 110, multiple support portions can be added; each support portion maintains a certain distance to ensure stable support for the relay rod 110 at different extension lengths. Both the first and second support portions are mounted on a moving mechanism and can move synchronously with the extension of the relay rod 110. The support portions can move smoothly as the rod extends, maintaining constant contact with the rod and preventing bending due to excessive hanging. The multiple support portions further enhance the stability and adaptability of the entire support mechanism 600, enabling the device to handle relay rods 110 of different lengths and weights.

[0058] For example, when the pole extends 0% to 50%, the first support part 610 provides the main support, while the second support part is on standby. After the pole extends 50%, the second support part is activated, sharing the load with the first support part 610 to prevent the end from sagging.

[0059] Further, please see Figure 4 or Figure 9 The first supporting part 610 includes a moving part 630 and a receiving part 640. In this embodiment, the receiving part 640 is configured as a clamping mechanism. The clamping mechanism includes a support frame 612 and a pair of clamping parts 611 symmetrically arranged on one side of the support frame 612. The clamping part 611 includes a clamping cylinder and an abutment block 613 disposed on the piston rod of the clamping cylinder. In use, the clamping cylinder drives the abutment block 613 to flexibly clamp, which prevents slippage and avoids damaging the surface of the rod (e.g., using an abutment block 613 covered with polyurethane).

[0060] Furthermore, a clamping space 614 is formed between a pair of clamping parts 611 symmetrically arranged on the support frame 612. The clamping or releasing of the relay rod 110 is achieved by the pair of abutting blocks 613 moving closer or further apart. An auxiliary limiting frame 615 is also provided on the abutting block 613 of the clamping part 611. Adding a "V", "U", or arc-shaped limiting frame to the abutting block 613 can further limit the lateral displacement of the rod, ensuring it remains horizontal; and the auxiliary limiting frame 615 moves synchronously with the movement of the abutting block 613.

[0061] Further, please see Figure 3The moving mechanism includes a pair of spaced-apart moving guide rails 710 and a moving seat 730 connected to the moving guide rails 710 via a moving slider 720. The supporting mechanism 600 is connected to the guide rails via the moving slider 720 and its moving speed is controlled by a driving component 740 (such as a servo motor, hydraulic cylinder, or lead screw), synchronized with the extension speed of the rod, and dynamically adjusted to ensure that the support point is always located near the center of gravity of the rod.

[0062] Please see Figure 5 The first support portion 610 and the second support portion are respectively disposed on different movable seats 730; the first support portion 610 and the second support portion are configured identically; the movable seat 730 of the first support portion 610 is connected to the driving component 740. The movable seat 730 of the first support portion 610 is connected to the driving component 740, and the movable seats 730 of other support portions move in tandem with the other portions; the connection between the movable seat 730 of the first support portion 610 and the driving component 740 can also apply a force to assist in removing the relay rod 110, thereby making disassembling the relay rod 110 easier and improving work efficiency. Furthermore, this design ensures that the support portion can move smoothly and accurately during the removal of the relay rod 110, avoiding unnecessary damage to the rod. The identical configuration of the first support portion 610 and the second support portion ensures functional and performance matching, making the entire support mechanism 600 more stable and reliable. The other support seats, by moving synchronously with the movable seat 730 of the first support part 610, can ensure the balance and stability of the relay rod 110 during the removal process.

[0063] The moving part 630 is provided with universal drive wheels 631 for movement.

[0064] Example 3

[0065] Please see Figure 1 This utility model embodiment provides a relay rod vibration device. Since the support mechanism in embodiment 1 requires a sliding guide rail 511 to receive the relay rod 110, it may be inconvenient to install the sliding guide rail 511 in some scenarios. Furthermore, it may also be inconvenient to install the auxiliary vibration mechanism 500.

[0066] Please see Figure 6 Therefore, this embodiment provides a relay rod vibration device for protecting the relay rod 110 during vibration in scenarios where it is inconvenient to install the sliding guide rail 511 and the vibration mechanism 500. This reduces systemic defects such as rod imbalance and tipping, mechanical damage, and risks associated with multi-person collaboration caused by the traditional air blowing method.

[0067] Please see Figure 6In this embodiment, the relay rod vibration device includes a blowing mechanism 200 and a workbench 310 for placing the relay 100; the workbench 310 is provided with a base plate 311 and a side plate 312 arranged perpendicularly to the base plate 311; the base plate 311 is provided with a clamp for fixing the relay 100; it also includes a support mechanism 600 that can move freely based on the workbench 310, the support mechanism 600 is used to receive the vibrated relay rod 110, and can move synchronously based on the vibration of the relay rod 110.

[0068] Please see Figure 6 In this embodiment, the supporting mechanism does not require a sliding guide rail 511 and can move directly on the work site, thus avoiding the problem of not being able to install the sliding guide rail 511 due to site limitations. The design of the supporting mechanism allows it to adapt to different working environments, improving the flexibility and applicability of the device. In addition, the movement method of the supporting mechanism can be adjusted according to actual needs, such as using external force push or electric drive, to meet the operational requirements in different scenarios.

[0069] Further, please see Figure 6 , Figure 7 and Figure 9 The supporting mechanism 600 includes at least a first supporting part 610 and a second supporting part 620; the first supporting part 610 includes a moving part 630 and a receiving part. The first supporting part 610 and the second supporting part 620 have the same structural configuration.

[0070] In this embodiment, please refer to Figure 7 The receiving part is an automatic adjustment structure; it includes a first adjustment part 641 and a second adjustment part 646 symmetrically arranged on the moving part 610; a bearing area 647 is provided between the first adjustment part 641 and the second adjustment part 646; the height of the bearing area 647 is synchronously adjusted with the relay rod 110.

[0071] The first adjustment unit 641 includes a mounting unit 642 and a support 643 that can be adaptively adjusted based on the mounting unit 642.

[0072] Please see Figure 8 The support seat 643 is provided with a support part 644. One end of the support part 644 is hinged to the support seat 643, and the other end is connected to the support seat 643 through a damping cylinder 645. When the support part 644 is in the original position, one end of the support part 644 abuts against the support seat 643.

[0073] In use, the item to be supported (relay rod 110) is placed in the bearing area 647. As the relay rod 110 extends, the bearing area 647, bearing the weight of the relay rod 110, adjusts its height accordingly to accommodate different height requirements, ensuring that all parts are at a consistent height or level. The first adjustment part 641 and the second adjustment part 646, through their structural design, ensure smooth lifting and lowering of the bearing area, preventing the relay rod 110 from swaying during support. The adaptive adjustment installation of the bearing seat 643 on the mounting part 642 allows the support mechanism 600 to adjust according to different extension heights of the relay rod 110, improving the stability and flexibility of support. The damping cylinder 645 further enhances the stability of the bearing part 643 during support; it retracts to adapt to the height of the relay rod 110 when subjected to its weight, and resets itself when the weight of the relay rod 110 is removed.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
