Description

Technical Field

[0001] This application relates to the field of pitch slip ring installation technology, and more specifically, to a pitch slip ring installation fixture. Background Technology

[0002] When installing the pitch slip ring, the pitch slip ring and the tube shaft must be on the same horizontal plane and the contact surface must be smooth and frictionless. If the angle is deviated, the tube shaft and the pitch slip ring interface will not be able to connect smoothly, resulting in installation failure. If the pitch slip ring is subjected to uneven force, the tube shaft and the pitch slip ring interface will collide, and the contact surface will become uneven, which will cause the pitch slip ring to get stuck and difficult to install.

[0003] The existing method of installing the pitch slip ring requires two people to work together. One person needs to apply a vertical upward force to the pitch slip ring to make it parallel to the horizontal plane of the tube shaft, while the other person adjusts the installation angle of the pitch slip ring from behind to connect the pitch slip ring interface to the tube shaft.

[0004] The installation method of the pitch slip ring has the following technical problems: the installation process of the pitch slip ring is time-consuming, labor-intensive and inefficient. Because the pitch slip ring itself is heavy and the installation space is small, it requires a high level of physical strength from the personnel supporting it below. If the personnel are not physically strong enough, there is a risk of collision. Utility Model Content

[0005] To address at least one of the aforementioned technical problems, this application proposes a pitch slip ring installation fixture.

[0006] In view of this, this application proposes a pitch slip ring installation fixture, comprising: a base; a hydraulic telescopic rod disposed on the base; a clamp disposed on the hydraulic telescopic rod, the clamp being used to detachably fit and fix the pitch slip ring; and a roller disposed below the base.

[0007] In some feasible implementations, the hydraulic telescopic rod includes: a sleeve disposed on a base; and a movable rod passing through the sleeve and connected to a clamp, the movable rod being capable of sliding relative to the sleeve.

[0008] In some feasible implementations, the pitch slip ring mounting fixture also includes: an adjusting wrench, located on the hydraulic telescopic rod, for pressurizing or depressurizing to adjust the extension length of the movable rod.

[0009] In some feasible implementations, the clamp includes at least two openable arc-shaped clamps connected by a swivel.

[0010] In some feasible implementations, the rollers are casters, which include braking devices for movement and positioning.

[0011] In some feasible implementations, a flexible pad is provided on the inside of the clamp to protect the outer surface of the pitch slip ring.

[0012] In some feasible implementations, the hydraulic telescopic rod is equipped with a scale to indicate the telescopic length.

[0013] In some feasible implementations, the base has adjustable feet at the bottom to adjust the stability of the tooling.

[0014] In some feasible implementations, the pitch slip ring mounting fixture also includes a push rod, detachably mounted on the base, for providing a point of force application when the fixture is pushed.

[0015] In some feasible implementations, the pitch slip ring mounting fixture also includes a level, mounted on a base, for detecting the levelness of the fixture to ensure the alignment accuracy between the pitch slip ring and the tube shaft.

[0016] Compared with the prior art, this application has the following technical effects:

[0017] The pitch slip ring installation fixture provided in this application makes pitch slip ring installation safer and more convenient, effectively reduces installation errors, avoids damage to the tube shaft and pitch slip ring due to angular errors, avoids the risk of collisions due to personnel fatigue, increases work efficiency when replacing pitch slip rings, and significantly saves installation time.

[0026] 100 Pitch Slip Ring Installation Fixture, 110 Base, 120 Hydraulic Telescopic Rod, 122 Sleeve, 124 Movable Rod, 130 Clamp, 140 Roller, 150 Adjusting Wrench, 160 Rotary Rod. Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0029] The following reference Figure 1 The pitch slip ring mounting fixture 100 is described in some embodiments of this application.

[0030] like Figure 1 As shown, this application provides a pitch slip ring installation fixture 100, including: a base 110; a hydraulic telescopic rod 120 disposed on the base 110; a clamp 130 disposed on the hydraulic telescopic rod 120, the clamp 130 being used to detachably fit and fix the pitch slip ring; and a roller 140 disposed below the base 110.

[0031] The pitch slip ring installation fixture 100 provided in this application includes a base 110, a hydraulic telescopic rod 120, a clamp 130, and rollers 140. Using this fixture reduces manpower and operation time during installation. The base 110 and hydraulic telescopic rod 120 support the pitch slip ring, reducing the burden of manual lifting, lowering labor intensity, and minimizing the risk of impacts due to physical exhaustion.

[0032] The clamp 130 ensures the stability of the pitch slip ring during installation, preventing it from wobbling or shifting. Simultaneously, by adjusting the height and angle of the hydraulic telescopic rod 120, the relative position of the pitch slip ring and the tube shaft can be precisely controlled, ensuring that both are on the same horizontal plane and that the contact surfaces are smooth and frictionless during installation. This improves installation accuracy and reduces installation failures or jamming caused by angular deviations or uneven force.

[0033] The design of the hydraulic telescopic rod 120 and the clamp 130 enables the pitch slip ring to be quickly and accurately positioned and fixed, avoiding the tedious process of manual lifting and adjustment over a long period of time, thus significantly improving installation efficiency.

[0034] The pitch slip ring installation fixture 100 provided in this application has a simple structure and is easy to operate. Furthermore, the components are detachably connected, facilitating maintenance and replacement of damaged parts, thus extending the service life of the fixture.

[0035] like Figure 1 As shown, in some embodiments provided in this application, the hydraulic telescopic rod 120 includes: a sleeve 122 disposed on the base 110; and a movable rod 124 passing through the sleeve 122 and connected to the clamp 130, wherein the movable rod 124 is slidable relative to the sleeve 122.

[0036] In this embodiment, the hydraulic telescopic rod 120 includes a sleeve 122 and a movable rod 124. With the aid of hydraulic power, the movable rod 124 can slide within the sleeve 122 to achieve the telescopic function. The installation height of the pitch slip ring can be flexibly adjusted according to actual installation requirements, adapting to different installation environments and working conditions, and enhancing the applicability of the tooling.

[0037] The hydraulic telescopic rod 120 structure can provide a large load-bearing capacity and reliably support the weight of the pitch slip ring. After adjusting the height of the movable rod 124, it can ensure that the relative position of the movable rod 124 and the sleeve 122 is stable, thereby ensuring that the height of the pitch slip ring remains unchanged during installation, improving the accuracy of installation positioning, and avoiding installation deviations caused by height changes.

[0038] The hydraulic system provides stable power output, and the sliding process of the movable rod 124 is smooth, reducing swaying and impact, ensuring the precise position of the pitch slip ring during altitude adjustment, avoiding installation deviations due to unstable adjustment, and ensuring installation quality.

[0039] like Figure 1 As shown, in some embodiments provided in this application, the pitch slip ring mounting fixture 100 further includes: an adjusting wrench 150, disposed on the hydraulic telescopic rod 120, for pressurizing or depressurizing to adjust the extension length of the movable rod 124.

[0040] In this embodiment, the pitch slip ring mounting fixture 100 also includes an adjusting wrench 150. The adjusting wrench 150 is mounted on the hydraulic telescopic rod 120, allowing operators to quickly and conveniently pressurize or depressurize the hydraulic telescopic rod 120, simplifying the adjustment process of the extension length of the movable rod 124 and saving time and labor costs.

[0041] Operators can use the adjusting wrench 150 to make fine adjustments to the hydraulic system and precisely control the extension of the movable rod 124, so that the pitch slip ring can accurately reach the required installation height, meet different installation scenarios and precision requirements, effectively avoid installation errors caused by inaccurate adjustment, and ensure installation quality.

[0042] The presence of the adjusting wrench 150 allows the tooling to better adapt to various complex and changing installation environments. Whether in situations where space is limited or where installation precision requirements are extremely high, the length of the movable rod 124 can be flexibly adjusted using the adjusting wrench 150, thereby improving the tooling's versatility and practicality.

[0043] like Figure 1 As shown, in some embodiments provided in this application, the clamp 130 includes at least two openable arc-shaped clamps connected by a swivel rod 160.

[0044] In this embodiment, the openable arc-shaped clamp allows the pitch slip ring to be easily inserted or removed without complicated operations. During installation, the clamp is opened to place the slip ring in the appropriate position and then closed; disassembly is equally convenient, shortening the loading and unloading time of the tooling and pitch slip ring and improving work efficiency.

[0045] The combination of at least two arc-shaped clamps can better fit the shape of the pitch slip ring, and the opening and closing degree of the clamps can be flexibly adjusted through the 160-degree connection of the screw rod. It is suitable for pitch slip rings of different specifications and sizes, which enhances the versatility of the tooling and reduces the cost of changing tooling due to differences in slip ring size.

[0046] After the clamp is closed, the swivel rod 160 provides a reliable tightening force to firmly fix the pitch slip ring to the tooling, preventing shaking or displacement during installation, ensuring the stability and safety of the installation process, and ensuring that the pitch slip ring can be installed accurately and smoothly.

[0047] In some embodiments provided in this application, the roller 140 is a caster wheel, which includes a braking device for movement and positioning.

[0048] In this embodiment, by setting omnidirectional wheels, the tooling can be moved in all directions within the installation site, and the operator can push the tooling to turn freely and move flexibly within the installation site.

[0049] The swivel casters are equipped with a braking device that can quickly lock after reaching the target position, firmly fixing the tooling in place and preventing installation deviations caused by tooling movement during installation. This ensures installation accuracy and guarantees that the pitch slip ring can be accurately installed. It also enhances the safety of the installation process and prevents safety accidents caused by accidental slippage of the tooling.

[0050] In some embodiments provided in this application, the inner side of the clamp 130 is provided with a flexible pad, which is used to protect the outer surface of the pitch slip ring.

[0051] In this embodiment, the flexible gasket is soft and can buffer the pressure and friction between the clamp 130 and the outer surface of the pitch slip ring. During installation, even if the tooling is subjected to slight shaking or slightly greater operating force, the flexible gasket can prevent the clamp 130 from directly scratching or colliding with the pitch slip ring, preventing scratches, wear and other damage to its outer surface, and ensuring the integrity of the pitch slip ring's appearance and the stability of its performance.

[0052] The flexible gasket can adapt to the small irregular shapes on the outer surface of the pitch slip ring, increasing the contact area between the clamp 130 and the slip ring, making the fixation tighter and more snug, reducing the risk of loosening due to poor contact, ensuring the stability of the pitch slip ring during installation, and improving the installation quality.

[0053] In some embodiments provided in this application, the hydraulic telescopic rod 120 is provided with a scale for displaying the telescopic length.

[0054] In this embodiment, the scale on the hydraulic telescopic rod 120 can intuitively display the telescopic length of the movable rod 124. The operator can accurately adjust the height of the pitch slip ring according to the scale to ensure that it is in a precise relative position with the tube shaft, effectively avoiding installation failure due to height deviation, and greatly improving the accuracy and success rate of installation.

[0055] Without the need for additional measuring tools, the telescopic length can be quickly and accurately determined using a scale, reducing measurement and debugging time during installation, simplifying the operation process, and making installation work more efficient and faster, especially suitable for scenarios with strict requirements on installation time.

[0056] In some embodiments provided in this application, the bottom of the base 110 is provided with adjustable feet for adjusting the stability of the tooling.

[0057] In this embodiment, the adjustable feet can be flexibly adjusted according to the ground conditions of the installation site. When the ground is uneven, the height of each foot can be adjusted to keep the base 110 level, thereby allowing the entire fixture to be placed stably on the ground. This avoids affecting the installation accuracy of the pitch slip ring due to the fixture shaking or tilting, and ensures a smooth and reliable installation process.

[0058] Different installation sites have different ground conditions. The adjustable feet allow the tooling to adapt to a variety of complex environments, such as slightly sloping or uneven ground, which expands the scope of use of the tooling and improves its versatility. There is no need to change the installation site or make major modifications to the tooling due to ground problems.

[0059] Stable tooling provides a solid foundation for the installation of pitch slip rings, reduces installation errors caused by tooling instability, enables pitch slip rings to be accurately and smoothly connected to the tube shaft, improves installation quality, and reduces the risk of equipment failure due to subsequent installation problems.

[0060] In some embodiments provided in this application, the pitch slip ring mounting fixture 100 further includes a push rod, detachably mounted on the base 110, for providing a point of force application when pushing the fixture.

[0061] In this embodiment, the pitch slip ring mounting fixture 100 also includes a push rod. The push rod is detachably mounted on the base 110. When the fixture needs to be moved, the push rod is mounted on the base 110, providing the operator with an additional point of force application. The additional point of force application allows the operator to better control the balance when pushing the fixture, and the operator can hold the push rod with both hands to apply thrust more conveniently.

[0062] The detachable design allows the actuator to be used flexibly according to actual needs. When the tooling is not in use, the actuator can be removed; and in scenarios where frequent tooling relocation is required, it can be quickly installed, meeting the needs of different working conditions and improving the applicability of the tooling.

[0063] In some embodiments provided in this application, the pitch slip ring mounting fixture 100 further includes a level, which is disposed on the base 110 and is used to detect the horizontal state of the fixture to ensure the docking accuracy between the pitch slip ring and the tube shaft.

[0064] In this embodiment, the pitch slip ring mounting fixture 100 also includes a level. The level is mounted on the base 110 and can detect the horizontal state of the fixture in real time. When installing the pitch slip ring, the operator can precisely adjust the fixture position according to the level indicator to ensure it is horizontal, thereby ensuring that the pitch slip ring and the tube shaft are in the correct relative position during docking. This effectively avoids docking deviations caused by fixture tilting and improves docking accuracy.

[0065] By using a level to quickly determine the levelness of the tooling, operators can quickly adjust the tooling to the appropriate state without repeated adjustments and measurements, reducing time wasted during the installation process and speeding up the installation progress. This is especially suitable for scenarios with strict requirements on installation time.

[0066] Precise alignment helps ensure a stable and reliable connection between the pitch slip ring and the tube shaft, reducing vibration and wear problems caused by poor alignment during subsequent operation and extending the service life of the equipment.

[0067] In practical applications, such as Figure 1As shown, when installing the pitch ring, place the pitch ring on the front and rear pitch ring mounting fixtures 100. Adjust the clamp 130 to tighten the pitch ring by adjusting the screw rod 160. Adjust the height of the front and rear pitch ring mounting fixtures 100 using the adjusting wrench 150 so that the pitch ring interface is on the same horizontal plane as the tube shaft. Push the roller 140 at the bottom of the pitch ring mounting fixture 100 to slowly align the pitch ring interface with the tube shaft. Apply a horizontal thrust to the pitch ring. Once the pitch ring reaches the specified position, the installation is successful.
