Description

Technical Field

[0001] This utility model belongs to the technical field of rod-shaped post porcelain insulator manufacturing, specifically relating to a rod-shaped post porcelain insulator adhesive limiter. Background Technology

[0002] With the deepening of my country's "West-to-East Power Transmission" strategy and the accelerated implementation of smart grid construction, ultra-high voltage and extra-high voltage power transmission networks have formed a crisscrossing energy artery. As a key supporting component of the power system, the rod-shaped post porcelain insulator faces increasingly harsh service environments. It must not only withstand mechanical loads under normal operating conditions but also cope with multiple challenges such as extreme weather, pollution flashover, and earthquakes. Rod-shaped post porcelain insulators are generally composed of insulating components (ceramic parts) and metal flanges, bonded together with cement adhesive.

[0003] In the existing gluing process for rod-shaped post porcelain insulators, the impact of straightness accuracy on the rod-shaped post porcelain insulator is often overlooked. Excessive straightness deviation leads to uneven stress distribution at the critical cross-section when the rod-shaped post porcelain insulator is subjected to bending loads, thereby reducing its mechanical strength. Against this backdrop, the problem of insufficient straightness control in traditional gluing processes becomes increasingly prominent. Utility Model Content

[0004] The purpose of this invention is to provide a glued limiter for rod-shaped post porcelain insulators, which can solve the problem of insufficient straightness control of rod-shaped post porcelain insulators.

[0005] A rod-shaped post porcelain insulator adhesive limiter includes a ground support, a limit module, and a measurement module.

[0006] Limiting modules are installed on both the top and bottom sides of the floor support.

[0007] A measurement module is installed in the middle of the floor support.

[0008] The floor support is equipped with a support slide rail, and the limit module and the measurement module are installed on the support slide rail.

[0009] The specific structure of the bracket slide rail can be as follows:

[0010] The bracket slide rail includes protrusions, limit module slots, and measurement module slots.

[0011] The limit module slot and the measurement module slot are located on the protrusion.

[0012] The limiting module includes: a limiting rod, a limiting module slot, a first limiting semicircle, and a second limiting semicircle.

[0013] The two ends of the limiting rod are respectively fixed to the limiting module slot and the first limiting semicircle.

[0014] The first and second limiting semicircles are connected at both ends by bolts and nuts, respectively.

[0015] The measurement module includes: a measuring rod, a measurement module slot, and a dial indicator.

[0016] The measuring module slot and dial indicator are fixed at both ends of the measuring rod, respectively.

[0017] Multiple positioning holes are made on the floor support.

[0018] The limit module is fixed to the positioning holes on the upper and lower sides of the floor bracket by screws.

[0019] Positioning hole in the middle of the measurement module.

[0020] Its advantages are:

[0021] This device solves the following problems in the traditional adhesive bonding process for post insulators:

[0022] 1. Problem of inaccurate dynamic positioning.

[0023] Traditional processes involve manually visually adjusting the coaxiality of the porcelain components and flanges, which introduces a certain degree of axial misalignment error. This is particularly problematic when gluing multi-component, high-voltage insulators, as the lack of straightness measurement devices causes accumulated errors to exceed the standard straightness threshold, leading to a decline in the mechanical properties of the rod-shaped post porcelain insulators.

[0024] 2. Lack of monitoring during the binding process.

[0025] The existing process uses a sampling inspection method after the cement adhesive has cured. This method cannot obtain straightness deviation data in real time. When the deviation is detected during the factory sampling inspection, irreversible defects have already formed, resulting in a waste of labor and material costs.

[0026] 3. The problem of deviation during the solidification and stabilization stage.

[0027] During the initial to final setting stage of the cementitious adhesive, traditional fixtures rely solely on gravity for fixation. During this stage, temperature fluctuations or mechanical vibrations can cause secondary displacement of the porcelain components, leading to a decrease in the mechanical properties of the rod-shaped support porcelain insulator.

[0028] It has the following advantages:

[0029] 1. High-precision dynamic positioning and error control.

[0030] By using the segmented adjustable structure of the limit module, combined with the rigid support of the floor bracket, precise coaxiality adjustment of the ceramic parts and the flange is achieved, solving the problem of axial offset caused by manual visual adjustment in traditional processes.

[0031] When installing multi-component high-voltage insulators, it effectively suppresses cumulative errors, strictly controls straightness within the threshold required by the standard, and achieves higher accuracy. It also reduces uneven stress distribution at dangerous cross-sections and significantly reduces the risk of stress concentration.

[0032] 2. Real-time monitoring and straightness correction.

[0033] The dial indicator in the measurement module integrates a high-sensitivity sensor that can monitor straightness deviation data in real time during the gluing process, achieving closed-loop control of "gluing and calibration simultaneously" and avoiding the lag defects of traditional post-curing sampling inspections. Through dynamic feedback adjustments, the incidence of irreversible defects is reduced, rework rates and material waste are decreased, ultimately lowering overall production costs.

[0034] 3. Enhanced stability during the curing stage.

[0035] The limiting module uses a locking mechanism to provide continuous and stable mechanical constraints during the initial to final setting stages of the cement adhesive, effectively resisting secondary displacement caused by temperature fluctuations and external vibrations, thereby reducing the probability of a decrease in the mechanical strength of the product.

[0043] A rod-shaped post porcelain insulator adhesive limiter includes a ground support 1, a limit module 2, and a measurement module 3.

[0044] Limiting modules 2 are installed on the upper and lower sides of the floor support 1.

[0045] The limit module 2 can be fixed to the upper and lower sides of the floor bracket 1 with screws.

[0046] Measurement module 3 is installed in the middle of the floor support 1.

[0047] The measurement module 3 can be fixed to the middle of the floor support 1 with screws.

[0048] Furthermore, to facilitate the positioning and installation of the limit module 2 and the measuring module 3, a support slide rail 6 can be installed on the floor support 1. The limit module 2 and the measuring module 3 are installed on the support slide rail 6 for easy up and down movement and fixation.

[0049] Specifically, the floor support 1 is connected to the limiting module 2 and the measuring module 3 through a T-slot structure.

[0050] The vertical inner side of the floor support 1 is provided with a protrusion 7 (T-shaped), and the limiting module 2 and the measuring module 3 are respectively provided with corresponding limiting module slots 2.2 and measuring module slots 3.2, so that they can be fitted onto the port of the protrusion 7.

[0051] The specific structure of the limiting module 2 may include: a limiting rod 2.1, a limiting module slot 2.2 (T-shaped), a first limiting semicircle 2.3, and a second limiting semicircle 2.4.

[0052] The two ends of the limiting rod 2.1 are respectively fixed to the limiting module slot 2.2 and the first limiting semicircle 2.3.

[0053] The first limiting semicircle 2.3 and the second limiting semicircle 2.4 are connected at both ends by bolts and nuts, respectively.

[0054] The specific structure of the measuring module 3 may include: a measuring rod 3.1, a measuring module slot 3.2 (T-shaped), and a dial indicator 3.3.

[0055] The measuring module slot 3.2 and the dial indicator 3.3 are fixed at both ends of the measuring rod 3.1, respectively.

[0056] The usage method is as follows:

[0057] Place the floor support 1 on one side of the working platform of the binding machine, level the support base with a level and fix it to ensure that its vertical axis is basically parallel to the center line of the binding machine, and fix the floor support 1 to prevent displacement during operation.

[0058] Based on the structural dimensions of the rod-shaped post porcelain insulator 4, a matching limiting module 2 and a measuring module 3 are selected. The limiting module 2 and the measuring module 3 are installed on the vertical support slide rail 6 pre-installed on the ground support 1. Figure 1 As shown.

[0059] Limit module 2 adopts a two-part locking mechanism, which clamps the ceramic part in segments along the axis of the ceramic part to suppress the cumulative error of straightness.

[0060] Measurement module 3 integrates a dial indicator 3.3 measuring instrument, which collects straightness data in real time through a rotating adhesive binding platform to achieve dynamic calibration.

[0061] Clean the flange assembly surface of the clean rod-shaped post porcelain insulator 4, fix the bottom flange on the bottom platform of the gluing machine 5, inject the prepared cement adhesive into the inner cavity of the top flange and the inner cavity of the bottom flange, connect the first limiting semicircle 2.3 and the second limiting semicircle 2.4 located below with bolts and nuts to form a circle, and position the limiting module 2 located below above the bottom flange. Hoist the cylindrical porcelain piece to the top of the bottom flange, and initially position the lower part of the porcelain piece through the circle-shaped locking mechanism formed by the limiting module 2 below, ensuring that the gap between the bottom end of the porcelain piece and the inner hole of the bottom flange is uniform, and place the porcelain piece into the inner cavity of the bottom flange.

[0062] Operate the adhesive binding machine 5 to slowly press down the top flange, and use bolts and nuts to connect the first limiting semicircle 2.3 and the second limiting semicircle 2.4 located above to encircle the top of the ceramic piece. The circular position formed by the upper limiting module 2 is located at the "upper neck" of the ceramic piece. Use bolts to fix the upper and lower limiting modules to the multiple positioning holes opened on the floor support 1.

[0063] After the two flanges are installed, the dial indicator 3.1 of the measuring module 3 is positioned horizontally along any horizontal position of the axis of the rod-shaped post porcelain insulator 4. The measuring module 3 is then fixed to the corresponding positioning hole on the floor bracket 1 using bolts. The second limiting semicircles 2.4 at the top and bottom are released, and the rod-shaped post porcelain insulator 4 is rotated 360° at a uniform speed via the glue-fitting platform turntable. Each 360° rotation of the rod-shaped post porcelain insulator 4 is recorded once, and the data is summarized in real time on the computer. The computer is used to collect the straightness data and images of the rod-shaped post porcelain insulator 4 in real time to determine the direction of the deviation. If the deviation is too large, the operator can manually adjust the straightness of the porcelain component.

[0064] After straightness adjustment, the two sets of first limiting semicircles 2.3 and second limiting semicircles 2.4, located at the top and bottom respectively, are bolted together. After the cement adhesive has initially set, the mechanical locking force of the locking mechanism (first limiting semicircle 2.3 and second limiting semicircle 2.4) of the limiting module 2 provides radial constraint force. Until the cement has finally set and the adhesive bonding process is completed, the constraints of the first limiting semicircles 2.3 and second limiting semicircles 2.4 are released, and the straightness is retested. Defective products are rejected, reducing the manpower and time costs of subsequent inspection processes.

[0065] The limiting module 2 and the measuring module 3 can slide and be fixed in the vertical direction of the floor support 1 according to the limiting and measuring positions.

[0066] This device solves the problems of large manual positioning errors, delayed sampling inspection after curing, and secondary offset during the curing stage in traditional processes, thereby improving the accuracy of straightness control, increasing bending failure load, and reducing overall production costs.

[0067] The limiting module 2 is used to limit and fix the ceramic part when the gluing begins. Before the straightness measurement method is implemented, the limiting module 2 is released. After the straightness of the ceramic part is adjusted, the limiting module is used again until the cement adhesive is completely cured.
