Description

Technical Field

[0001] This invention relates to the field of power fittings technology for power transmission lines, and more specifically, to a manufacturing method that can solve the assembly problem of the reinforced main body structure of anti-runaway spacer bars at low cost, high efficiency, and high precision. Background Technology

[0002] As per the instruction manual Figures 1 to 4 As shown, the reinforced main structure of the anti-runaway spacer (also known as an anti-disengagement tension buffer spacer) mainly includes two relatively spaced frames 231, and multiple wire clamps 232 and multiple rigid arc tubes 233 disposed between the two frames 231. The wire clamps 232 are evenly distributed along the circumference of the frames 231, and each rigid arc tube 233 is located between two adjacent wire clamps 232. Multiple bolt holes 2311 for arc tubes and bolt holes 2312 for wire clamps are provided on the frames 231. Arc tube mounting holes 2331 corresponding to the bolt holes 2311 are provided at both ends of the rigid arc tubes 233. The wire clamps 232 are fixedly connected to the two frames 231 using wire clamp bolt fasteners 235; the rigid arc tubes 233 are fixedly connected to the two frames 231 using arc tube bolt fasteners 234. The arc tube bolt fasteners 234 include arc tube bolts 2341 and arc tube nut assemblies 2342. The wire clamp bolt fastener 235 includes a wire clamp bolt 2351 and a wire clamp nut assembly 2352. The arc pipe nut assembly 2342 and the wire clamp nut assembly 2352 have the same structure and components, both consisting of a nut, an elastic washer, and a flat washer. The main difference between the two lies in the specific dimensional differences that arise to accommodate bolts of different specifications.

[0003] Therefore, the reinforced main structure of the anti-runaway spacer bar to be assembled in this invention is characterized by numerous parts and a compact assembly space. During assembly, if the conventional "sequential assembly of individual parts" method is used, the bolts not yet connected to the nut assembly are in an "unrestrained" state. When inserting and positioning adjacent parts, displacement or detachment is easily caused due to the lack of fixation, resulting in frequent process interruptions and low assembly efficiency. If the "step-by-step assembly method" of first fixing the frame to the clamps and then installing the rigid arc tube is used, the rigid arc tube needs to be installed between the already fixed frames, resulting in limited operating space and a lack of visual alignment reference, making it a time-consuming, labor-intensive, and precision-uncontrollable "blind assembly" operation. Therefore, existing conventional assembly methods are insufficient to achieve efficient, accurate, and reliable assembly of the main structure of this invention. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a manufacturing method that can solve the assembly problem of the reinforced main structure of the anti-runaway spacer bar in a low-cost, high-efficiency, and high-precision manner.

Step 5: Assemble the wire clamps; Using the pins of the wire clamps as the positioning reference, fit the bolt mounting holes of the wire clamps onto the corresponding pins of the wire clamps, and make the wire clamps fit against the corresponding mounting surfaces of the lower frame; complete the positioning of all wire clamps one by one. Step Six: Rigid Arc Tube Assembly; Using the jack for the arc tube as the positioning reference, fit the arc tube mounting hole of the rigid arc tube onto the corresponding jack for the arc tube, and make the rigid arc tube fit against the corresponding mounting surface of the lower frame; complete the positioning of all rigid arc tubes one by one. Step 7: Positioning and installing the upper frame; Use another frame as the upper frame; using the arc tube ejector pin and the wire clamp ejector pin as positioning references, fit the arc tube bolt holes and the wire clamp bolt holes of the upper frame onto the corresponding ejector pins respectively, and attach the frame to the upper surface of the product obtained in step six. Step 8: Initially tighten the bolts; Using the lead pin for the wire clamp as a guide, press down the bolt for the wire clamp and screw it into the corresponding nut assembly for the wire clamp; using the lead pin for the arc tube as a guide, press down the bolt for the arc tube and screw it into the corresponding nut assembly for the arc tube; complete the initial tightening of all bolt fasteners one by one; Step Nine: Final tightening and assembly complete; Tighten all bolts and fasteners in sequence according to the preset torque value, and the main structure assembly is completed.

[0006] Preferably, the ejector pin for the arc tube and the ejector pin for the wire clamp are supported and reset by an ejector pin reset mechanism; The ejector pin reset mechanism includes multiple ejector pin boxes fixed to the back of the annular worktable and evenly distributed along the circumference of the annular worktable. Each of the aforementioned ejector pin boxes is provided with an arc tube spring groove corresponding to the position of the arc tube ejector pin, and a wire clamp spring groove corresponding to the position of the wire clamp ejector pin; The arc tube spring is provided in the spring groove of the arc tube, and the wire clamp spring is provided in the spring groove of the wire clamp.

[0026] Example 1

[0027] like Figures 5 to 10As shown, this embodiment provides a low-investment manufacturing method for a reinforced main structure with anti-runaway spacers, which specifically includes the following steps: Step 1: Prepare the frame 231, wire clamp 232, rigid arc tube 233, arc tube bolt fastener 234, and wire clamp bolt fastener 235 for later use. The frame 231 has bolt holes 2311 for the arc tube and bolt holes 2312 for the wire clamp. The rigid arc tube 233 has arc tube mounting holes 2331 at both ends. The arc tube bolt fastener 234 includes an arc tube bolt 2341 and an arc tube nut assembly 2342. The wire clamp bolt fastener 235 includes a wire clamp bolt 2351 and a wire clamp nut assembly 2352.

[0028] Step 2: Prepare dedicated assembly device 3 for later use; The dedicated assembly device 3 includes a clamping mechanism 32 and a ring-shaped worktable 31. The ring-shaped worktable 31 is provided with a wire clamp receiving area 311 and a frame receiving area 312. The frame receiving area 312 is provided with multiple arc tube nut assembly receiving slots 3121 and multiple wire clamp nut assembly receiving slots 3122. The positions of the arc tube nut assembly receiving slots 3121 correspond one-to-one with the positions of the arc tube bolt holes 2311; the positions of the wire clamp nut assembly receiving slots 3122 correspond one-to-one with the positions of the wire clamp bolt holes 2312.

[0029] Furthermore, each arc tube nut assembly receiving groove 3121 is coaxially provided with a reciprocating arc tube ejector pin 313, and each wire clamp nut assembly receiving groove 3122 is coaxially provided with a reciprocating wire clamp ejector pin 314. Both the arc tube ejector pin 313 and the wire clamp ejector pin 314 penetrate the annular worktable 31, and their top ends protrude from the working surface of the annular worktable 31 in the initial state. The function of the arc tube ejector pin 313 and the wire clamp ejector pin 314 is to provide guidance for stacked components. Therefore, in the initial state, they must protrude from the working surface of the annular worktable 31, and their height must be sufficient.

[0030] Step 3: Insert the nut assembly; Arc tube nut assemblies 2342 are placed one by one into each nut assembly receiving slot 3121 for arc tubes; wire clamp nut assemblies 2352 are placed one by one into each nut assembly receiving slot 3122 for wire clamps. The nut assemblies 2342 and 2352 for arc tubes have the same structure and components, both consisting of nuts, elastic washers, and flat washers. The main difference between them lies in the specific dimensional differences to accommodate bolts of different sizes. The nuts, elastic washers, flat washers, and other parts in each nut assembly are stacked in an orderly manner according to design requirements when placed into the receiving slots.

[0031] Step 4: Positioning and installing the lower frame; One of the frames 231 is used as the lower frame; with the arc tube pin 313 and the wire clamp pin 314 as the positioning reference, the arc tube bolt hole 2311 and the wire clamp bolt hole 2312 of the lower frame are respectively fitted onto the corresponding pins, and the frame is pushed down so that the frame is stably positioned in the frame receiving area 312.

[0032] Step 5: Assemble the wire clamps; Using the pin 314 for the wire clamp as the positioning reference, the bolt mounting hole of the wire clamp 232 is fitted onto the corresponding pin 314 for the wire clamp, and the wire clamp 232 is pushed down so that the wire clamp 232 fits against the corresponding mounting surface of the lower frame; in this way, the positioning of all wire clamps 232 is completed one by one.

[0033] Step Six: Rigid Arc Tube Assembly; Using the arc tube ejector pin 313 as the positioning reference, the arc tube mounting hole 2331 of the rigid arc tube 233 is fitted onto the corresponding arc tube ejector pin 313, and the rigid arc tube 233 is pushed down so that the rigid arc tube 233 fits into the corresponding mounting surface of the lower frame; in this way, the positioning of all rigid arc tubes 233 is completed one by one.

[0034] Step 7: Positioning and installing the upper frame; Use another frame 231 as the upper frame; using the arc tube pin 313 and the wire clamp pin 314 as positioning references, put the arc tube bolt hole 2311 and the wire clamp bolt hole 2312 of the upper frame onto the corresponding pins respectively, and push the upper frame down so that the frame fits into place with the upper surface of the product obtained in step six.

[0035] Step 8: Initially tighten the bolts; Subsequently, guided by the wire clamp pin 314, the wire clamp bolt 2351 is pressed down and screwed into the corresponding wire clamp nut assembly 2352. Specifically, the wire clamp bolt 2351 passes through the flat washer and the elastic washer before being tightened into the nut of the wire clamp nut assembly 2352. At this point, rotating it several times provides a pre-fixation of the wire clamp bolt 2351. Similarly, guided by the arc tube pin 313, the arc tube bolt 2341 is pressed down and screwed into the corresponding arc tube nut assembly 2342. In this way, the initial tightening of all bolt fasteners is completed one by one.

[0036] Step Nine: Final tightening and assembly complete; According to the preset torque value, use a pneumatic wrench and other installation tools to tighten all bolts and fasteners in sequence. At this point, the main body structure of the anti-runaway spacer bar reinforcement in this embodiment is assembled. Then, remove the assembled main body structure upwards. At this time, the arc tube ejector pin 313 and the wire clamp ejector pin 314 are automatically reset under the action of the reset mechanism, and the special assembly device can continue to be used for the cyclic assembly of the next main body structure. Figures 5 to 7To clearly show the stacking relationship of each layer of components, the diagram shows a section of the main structure of the anti-runaway spacer reinforced main structure.

[0037] The assembly method provided in this embodiment uses a dedicated assembly device structure that is easy to implement and solves the assembly problem of the anti-runaway spacer reinforced main structure with extremely low investment cost.

[0038] This embodiment utilizes a dedicated assembly device to provide a unique and precise three-dimensional spatial reference for all components (frame, clamps, rigid arc tubes, bolt and nut assemblies, etc.), enabling the layering and "one-time alignment" of all parts to be assembled, ensuring the continuity of the assembly process. This effectively overcomes the bottlenecks of traditional "disassembled component assembly" where bolts are prone to falling off and procedures are cumbersome, and the "blind assembly" of rigid arc tubes in "step-by-step assembly" suffers from poor accuracy and low efficiency. Thus, it achieves efficient, precise, and consistent standardized assembly, significantly improving production efficiency. While significantly improving production efficiency, this method also provides a fundamental guarantee for the high quality and high reliability of the product.

[0039] Example 2

[0040] Based on Example 1, this example continues to describe in detail the technical features involved and the functions and roles of these technical features in the present invention, so as to help those skilled in the art to fully understand the technical solution of the present invention and reproduce it.

[0041] like Figures 5 to 10 As shown, in this embodiment, the arc tube ejector pin 313 and the wire clamp ejector pin 314 are supported and reset by the ejector pin reset mechanism 33. Specifically, the ejector pin reset mechanism 33 includes multiple ejector pin boxes 331 fixed to the back of the annular worktable 31 and evenly distributed around the circumference of the annular worktable 31. Each ejector pin box 331 has an arc tube spring groove corresponding to the position of the arc tube ejector pin 313 and a wire clamp spring groove 333 corresponding to the position of the wire clamp ejector pin 314. An arc tube spring is provided in the arc tube spring groove, and a wire clamp spring 335 is provided in the wire clamp spring groove 333. The bottom of the arc tube spring and the wire clamp spring 335 is sealed by a closing plate 336 that is fixedly connected to the bottom of the ejector pin box 331. One end of the arc tube spring presses against the closing plate 336, and the other end presses against the tail of the arc tube ejector pin 313. One end of the wire clamp spring 335 presses against the closing plate 336, and the other end presses against the tail of the wire clamp ejector pin 314. Both the arc tube spring and the wire clamp spring 335 are compression springs. Of course, the closing plate 336 is designed with guide bosses for fixing the ends of the springs.

[0042] In this embodiment, both the arc tube bolt 2341 and the wire clamp bolt 2351 are riveting bolts with blind holes at the tail. The heads of the arc tube ejector pin 313 and the wire clamp ejector pin 314 are provided with protrusions, which are respectively used to fit into the blind holes at the tails of the arc tube bolt 2341 and the wire clamp bolt 2351, thereby further improving the installation guiding speed and accuracy of each bolt.

[0043] Conventional spacer frames typically have mounting holes for anti-fighting devices. In this embodiment, frame 231 is interchangeable with conventional spacer frames, and the retained mounting holes 2313 for anti-fighting devices provide auxiliary positioning. Specifically, the frame receiving area 312 has positioning protrusions that match the mounting holes 2313 of frame 231. These positioning protrusions correspond to the positions of the mounting holes, facilitating auxiliary positioning when placing the lower frame.

[0044] In this embodiment, multiple clamping mechanisms 32 are evenly distributed along the inner ring of the annular worktable 31. Each clamping mechanism 32 includes a clamp seat 321 fixedly integrated with the inner ring of the annular worktable 31, on which a quick-clamping clamp 322 is fixedly mounted. After the upper frame is positioned, the quick-clamping clamp 322 is used to clamp it to prevent slight movement of the frame during subsequent bolt tightening, ensuring assembly accuracy. The annular worktable 31 has a hollowed-out section between adjacent wire clamp receiving areas 311, forming a hanging lug 315 for easy handling. This hollowed-out design serves two purposes: reducing weight while providing a handle function. The practical value of the dedicated assembly device 3 in this embodiment lies in its integrated positioning, clamping, and resetting mechanisms, which transform complex assembly into a standardized process, significantly improving assembly efficiency, accuracy, and product consistency. This device is easy to implement and has low implementation costs, allowing manufacturers to solve the assembly problem of the anti-runaway spacer reinforced main structure with minimal investment.

[0045] It should be noted that the sequence of steps described in the above embodiments is merely one specific implementation flow of the present invention. Those skilled in the art should understand after reading this application that some steps may not be performed in the aforementioned order without departing from the concept of the present invention. For example, steps five and six can be interchanged. Any rearrangement of the step order, as long as it employs the combination of steps described in this invention, should fall within the protection scope of this invention.

[0046] In summary, these are merely preferred embodiments of the present invention and are not intended to limit the scope of the invention. All equivalent variations and modifications made in accordance with the shape, structure, features, and spirit of the claims of the present invention should be included within the scope of the claims of the present invention.
