Description

Technical Field

[0001] This utility model relates to the field of pipe adjustment technology, specifically a large-span pipe deflection adjustment device. Background Technology

[0002] With the increasing demand for compact substation designs and large-span layouts, the span of busbars is constantly increasing, typically exceeding 15 meters and even reaching over 30 meters. Under the long-term effects of self-weight, wind load, snow and ice load, and thermal expansion and contraction, large-span busbars are prone to significant sag deflection, affecting electrical safety distances and overall structural stability. Therefore, effective deflection adjustment devices must be installed.

[0003] The common practice is to install adjustable support rods or suspension cables under the main pipe, using threads to adjust the height and offset some of the sagging. However, these devices are mostly placed directly under the main pipe, with the support point fixed in one position. The main pipe is a long, continuously stressed component, and its sagging is a uniformly distributed "arc-shaped bend," not concentrated at a single point. If the support is rigidly applied to only one point, although it may appear to raise the pipe locally, it actually alters the original stress state of the main pipe, easily creating new stress concentration zones near the support point. This can lead to localized deformation, damage, or even cracking of the main pipe, ultimately affecting its long-term lifespan. Furthermore, this "rigid support" method cannot truly restore the entire main pipe to a smooth curve, and its adjustment effect is limited. Utility Model Content

[0004] The purpose of this utility model is to provide a large-span pipe busbar deflection adjustment device to solve the problem mentioned in the background art that the current large-span pipe busbar deflection adjustment devices use point-type rigid supports, which leads to uneven force on the pipe busbar and easy stress concentration, causing local damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-span pipe shank deflection adjustment device, comprising an adjustable support rod, the top of which is fixedly connected to a laterally extending main support platform, a flexible support component fixedly installed on the main support platform, the flexible support component comprising a pair of parallel lateral mounting seats, a laterally arranged corrugated elastic beam fixedly connected between the lateral mounting seats, the top of the corrugated elastic beam having a plurality of upwardly protruding arc-shaped support portions continuously provided along its length direction, the top surfaces of the arc-shaped support portions collectively forming a continuous support surface matching the natural drooping curve of the pipe shank to be supported.

[0006] Preferably, the main support platform is a rectangular steel plate with mounting holes at its four corners and a connecting sleeve welded to its center. The connecting sleeve is fitted onto the top of the adjustable support rod and locked with screws.

[0007] Preferably, the lateral mounting base is a U-shaped metal bracket, the base plate of which is fixed to the main support platform by screws, and threaded holes are provided on the two upright plates of the lateral mounting base, with butt bolts inserted into the inside of the threaded holes.

[0008] Preferably, the corrugated elastic beam is formed by cold pressing of a thin metal sheet, and its cross-section is sinusoidal. Both ends are fixed to the inner wall of the lateral mounting base by bolts.

[0010] Preferably, the top of the arc-shaped support is bonded with flexible silicone, and the surface of the flexible silicone is provided with staggered anti-slip ridges.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This large-span pipe jack deflection adjustment device provides continuous support through an arc-shaped bracket, avoiding local stress concentration, effectively preventing damage to the pipe jack, resulting in more uniform force distribution and safer and more reliable adjustment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: a large-span pipe shank deflection adjustment device, including an adjustable support rod 1, with a laterally extending main support platform 2 fixedly connected to the top of the adjustable support rod 1. A flexible support component is fixedly installed on the main support platform 2, and the flexible support component includes a pair of parallel lateral mounting seats 3. A laterally arranged corrugated elastic beam 4 is fixedly connected between the lateral mounting seats 3. The top of the corrugated elastic beam 4 has multiple upwardly protruding arc-shaped support parts 5 continuously provided along its length direction. The top surfaces of the arc-shaped support parts 5 together form a continuous support surface that matches the natural drooping curve of the pipe shank to be supported. This structure raises and lowers the entire device to a predetermined height through the adjustable support rod 1, causing the main support platform 2 to move the flexible support component on it upwards synchronously. After the drooping part of the gantry comes into contact with the arc-shaped support 5, the pressure is borne by multiple arc-shaped support 5s. Since these support 5s are integrated at the crests of the corrugated elastic beam 4, and the corrugated elastic beam 4 is fixed to the main support platform 2 by the lateral mounting base 3, the drooping force of the gantry is evenly transmitted to each crest of the corrugated elastic beam 4. Its sinusoidal waveform structure disperses the concentrated load into continuous elastic deformation along the beam length, and the trough areas subsequently produce coordinated bending, making the entire support surface fit more naturally with the gantry. This avoids excessive local stress caused by traditional single-point hard jacking. Meanwhile, the main support platform 2, as the basic load-bearing platform, ensures that all components work together, ultimately achieving continuous, flexible, and adaptive support for the entire length of the gantry, effectively solving the problem of… This design addresses the problems of stress concentration, localized damage to the main support tube, deformation, and even cracking caused by point-support in existing technologies, significantly improving the uniformity and operational safety of the support. The main support platform 2 is a rectangular steel plate with mounting holes at its four corners and a connecting sleeve 6 welded to its center. The connecting sleeve 6 is fitted onto the top of the adjustable support rod 1 and locked with screws. This structure allows the main support platform 2 to achieve quick alignment and stable connection with the adjustable support rod 1 via the connecting sleeve 6. The screw locking method facilitates installation and fixation after height adjustment. The mounting holes at the four corners provide positioning references and connection interfaces for the assembly of the flexible support components. The overall structure is compact and the connection is reliable. The lateral mounting base 3 is a U-shaped metal bracket, whose base plate is fixed to the main support platform 2 with screws. Threaded holes are provided on the two side plates of the mounting base 3, and mating bolts 7 are inserted into the threaded holes. This structure uses the U-shaped lateral mounting base 3 to stably fix the corrugated elastic beam 4 to the main support platform 2. The mating bolts 7 pass through the threaded holes of the vertical plates to clamp the ends of the elastic beam, ensuring effective transmission of bearing force. At the same time, the bolt connection method facilitates disassembly and maintenance. The overall structure is sturdy and flexible in assembly. The corrugated elastic beam 4 is formed by cold pressing of a thin metal sheet. Its cross-section is sinusoidal. Both ends are fixed to the inner side wall of the lateral mounting base 3 by bolts. This structure of the corrugated elastic beam 4 utilizes the geometric characteristics of the sinusoidal waveform to give the elastic beam good bending flexibility and axial stability, so that it can deform evenly and distribute stress when bearing the load of the tube, avoiding local overload.The cold-pressing process ensures waveform accuracy and structural strength. Bolted connections at both ends facilitate installation and adjustment, ensuring coordinated stress distribution throughout the support system. The corrugated elastic beam 4 has seven crests, a wave pitch of 80mm, an amplitude of 25mm, a plate thickness of 3mm, and is made of 65Mn spring steel. This structure uses seven crests to achieve continuous multi-point support, forming a support surface that matches the sag curve of the tube shank. The plate thickness, combined with the spring steel material, ensures sufficient elastic deformation capacity while possessing excellent fatigue resistance, ensuring no deformation or failure under long-term load. The top of the arc-shaped support part 5 is bonded with flexible silicone 8, whose surface has staggered anti-slip ridges. This structure effectively buffers the contact stress between the tube shank and the support part through the flexible silicone 8, preventing scratches or indentations on the metal surface. The staggered anti-slip ridges increase friction, preventing slippage of the tube shank during operation and improving the stability and safety of the support.

[0016] Working principle: When using this large-span pipe nut deflection adjustment device, firstly, the adjustable support rod 1 is installed on the foundation embedded parts and initially fixed. Then, the main support platform 2 is fitted onto the top of the adjustable support rod 1 through the connecting sleeve 6 at its bottom and temporarily locked with screws. Next, a pair of lateral mounting seats 3 are installed in the four corner mounting holes of the main support platform 2 through the base plate screws. Then, the two ends of the corrugated elastic beam 4 are aligned with the inner side of the vertical plate of the lateral mounting seat 3, and the butt bolts 7 are used to clamp and fix it through the threaded holes on the vertical plate to ensure that the corrugated elastic beam 4 is horizontally and stably connected between the two seats. After that, check the tightness of each connection part. After confirming that there are no problems, the main support platform 2 and the flexible support component above it are gradually raised by rotating the lifting mechanism of the adjustable support rod 1 until the multiple arc-shaped support parts 5 at the top of the corrugated elastic beam 4 are in full contact with the large-span pipe nut below and bear the force. Finally, the screws of the connecting sleeve 6 and each butt bolt 7 are completely locked to complete a series of operations.
