Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, and in particular to an overhead fixing frame for silicon core tubes. Background Technology

[0002] In the fields of telecommunications and power engineering, silicon core tubes are widely used in overhead pipeline laying in scenarios such as viaducts due to their high strength and corrosion resistance. Their fixing devices need to adapt to installation requirements in complex terrains. Currently, most mainstream silicon core tube overhead fixing frames adopt a fixed vertical angle steel and bracket welded structure, with tube boxes installed by bolt tightening. When facing installation environments with inclined or curved sides of viaducts, this design requires manual installation of shims or cutting of steel frames to adapt the angle, resulting in low construction efficiency and compromised structural stability.

[0003] A Chinese patent with publication number CN220787634U discloses a silicon core tube laying bracket. This bracket, consisting of a base, lower support, column, upper support, horizontal tube, threaded rod, and side plates, limits the inner and top sides of the silicon core tube tray. A rotatable horizontal tube runs through the middle of the column, with threaded connections at both ends to a first and second threaded rod, which in turn opens the side plates to the inside of the silicon core tube tray. The upper support is detachably connected to the top of the column via a plug rod, restricting the top of the silicon core tube tray. The base has omnidirectional brake wheels for easy movement. However, this design requires manual rotation of the horizontal tube to adjust the threaded rod, which is inconvenient and time-consuming. The side plates are only opened by the threaded rod, lacking elastic cushioning and easily damaging the silicon core tube tray. The support and column are connected by a plug rod, limiting the angle adjustment range and making it unsuitable for different construction conditions. Furthermore, the overall structure is not foldable, resulting in a large footprint.

[0004] In response to the aforementioned technologies, a silicon core tube overhead mounting bracket is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] This utility model proposes a silicon core tube overhead fixing bracket, which solves the problems of complex installation, inconvenient angle adjustment, and large space occupation of existing silicon core tube overhead fixing devices.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a silicon core tube overhead fixing frame, including: a vertical angle steel, a bracket movably connected to one end of the vertical angle steel, a fixing angle steel symmetrically fixed on the bracket, and a tube box detachably connected to the fixing angle steel by bolts. The vertical angle steel includes an upper steel frame and a lower steel frame. Self-locking structures are fixedly provided on the outer walls of both sides of the lower steel frame. The upper steel frame and the lower steel frame are hinged through the self-locking structures.

[0007] The self-locking structure includes a linkage shaft, a mounting base, and a locking rod. The linkage shaft is fixedly connected to the bottom end of the upper steel frame and passes through the lower steel frame. Both ends of the linkage shaft are rotatably connected to the mounting base. The mounting base is fixedly connected to the top two sides of the lower steel frame. The mounting base has a sliding groove and a slot respectively opened in the vertical direction. The linkage shaft has an internal hollow structure and multiple adjustment holes are distributed around the outer wall of both ends. The locking rod is slidably connected in the sliding groove.

[0008] The upper steel frame is designed in a U-shape and can be rotated in the opposite direction to fold into the inside of the lower steel frame.

[0009] Preferably, the locking rod includes two vertical rods, a connecting plate, and a damping spring. The ends of the two vertical rods are fixedly connected to the connecting plate. A damping spring is sleeved on one end of the vertical rod and is located between the connecting plate and the mounting base. A limit pin is screwed onto the connecting plate at the other end of the vertical rod. The limit pin passes through the slot and the adjustment hole in sequence.

[0010] Preferably, an angle adjustment block is fixedly installed at one end of the bracket that connects to the vertical angle steel. The angle adjustment block has a semi-circular arc structure and is hinged to the lower steel frame through a shaft.

[0011] Preferably, the angle adjustment block has an arc-shaped groove that runs through its arc surface.

[0012] Preferably, the lower steel frame sidewall is provided with multiple limiting holes at intervals along the extension direction of the arc groove.

[0013] Preferably, the limiting hole and the arc groove are connected by a locking bolt, and the locking bolt passes through the arc groove and locks into the limiting hole.

[0014] Compared with existing technologies, the advantages of this utility model include: the self-locking structure enables rapid locking and height adjustment of the upper and lower steel frames, improving installation efficiency; the combination design of the angle adjustment block, arc groove, and limiting hole allows for flexible adjustment of the bracket angle according to needs, ensuring the optimal mounting posture of the silicon core tube; the detachable tube box structure facilitates later maintenance and replacement, reducing usage costs; the Z-shaped upper steel frame can be rotated in the opposite direction and folded into the inner side of the lower steel frame, significantly reducing transportation and storage space; the combination design of damping spring and limiting pin effectively prevents the structure from loosening after adjustment, enhancing overall stability.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] According to one embodiment of the present invention, in conjunction with Figures 1-5As shown. A silicon core tube overhead fixing frame includes: a vertical angle steel 1, a bracket 2 movably connected to one end of the vertical angle steel 1, a fixing angle steel 3 symmetrically fixed on the bracket 2, and a tube box 4 detachably connected to the fixing angle steel 3 by bolts. The vertical angle steel 1 includes an upper steel frame 11 and a lower steel frame 12. Self-locking structures 5 are fixedly installed on the outer walls of both sides of the lower steel frame 12. The upper steel frame 11 and the lower steel frame 12 are hinged together by the self-locking structures 5. The linkage shaft 51 of the self-locking structure 5 cooperates with the locking rod 53 to realize the functions of pressing to unlock and automatically resetting to lock. The operator can press the connecting plate 533 with one hand to make the limit pin 535 disengage from the adjustment hole 510 (unlocking force ≤ 5N). The upper steel frame 11 can achieve stepless rotation adjustment from 0-180°. After adjustment, the limit pin 535 automatically resets and locks within 3 seconds under the action of the damping spring 534. The angle adjustment efficiency is improved compared with the traditional bolt fastening method. The upper steel frame 11 is designed with a U-shaped structure, which can be rotated in the opposite direction and folded into the inside of the lower steel frame 12. The U-shaped structure allows the overall height to be compressed to 1 / 3 of the original height after folding, which facilitates installation under different construction conditions and transportation and storage in confined spaces.

[0024] The self-locking structure 5 includes a linkage shaft 51, a mounting base 52, and a locking rod 53. The linkage shaft 51 is fixedly connected to the bottom end of the upper steel frame 11 and passes through the lower steel frame 12. Both ends of the linkage shaft 51 are rotatably connected to the mounting base 52, which is fixedly connected to both sides of the top of the lower steel frame 12. The mounting base 52 has a sliding groove 530 and a slot 531 respectively opened in the vertical direction. The linkage shaft 51 has an internal hollow structure and multiple adjustment holes 510 are distributed around the outer circumference of both ends. The locking rod 53 is slidably connected in the sliding groove 530. The hollow design of the linkage shaft 51 reduces the overall weight. The cooperation between the adjustment holes 510 and the limit pin 535 achieves precise locking at multiple angles with a 15° interval. The tapered insertion structure of the adjustment holes 510 and the limit pin 535 (with the contact surface inclined at 8°) achieves double anti-disengagement locking and can withstand a longitudinal tensile force of ≥500kg. The locking rod 53 includes two vertical rods 532, a connecting plate 533, and a damping spring 534. The ends of the two vertical rods 532 are fixedly connected to the connecting plate 533. A damping spring 534 is sleeved on one end of each vertical rod 532, located between the connecting plate 533 and the mounting base 52. A limit pin 535 is screwed onto the connecting plate 533 at the other end of the vertical rod 532. The limit pin 535 passes through the slot 531 and the adjustment hole 510 in sequence. The damping spring 534 is made of silicon-manganese alloy (elastic modulus 210 GPa), and its buffering efficiency decreases by less than 3% in 100,000 press tests. It provides buffering during adjustment, avoiding hard collisions between the limit pin 535 and the adjustment hole 510, thus extending the component's lifespan. An angle adjustment block 21 is fixedly installed at one end of the bracket 2 connected to the vertical angle steel 1. The angle adjustment block 21 has a semi-circular arc structure and is hinged to the lower steel frame 12 via a shaft. The arc-shaped surface design of the angle adjustment block 21 allows the bracket 2 to be precisely adjusted in 5° intervals within a ±25° pitch angle range, meeting the pipeline elevation compensation requirements in complex terrains such as mountainous areas and bridges. An arc-shaped groove 210 is formed on the angle adjustment block 21, penetrating its arc surface. Multiple limiting holes 120 are spaced along the extension direction of the arc-shaped groove 210 on the side wall of the lower steel frame 12. The limiting holes 120 are connected to the arc-shaped groove 210 by locking bolts, which penetrate the arc-shaped groove 210 and lock into the limiting holes 120. The threaded locking structure of the bolts and the limiting holes 120 enhances the load-bearing stability of the bracket 2 and prevents displacement caused by pipeline vibration.

[0025] In this embodiment, when the unfolding angle of the vertical angle steel 1 needs to be adjusted, the operator presses the connecting plate 533 to disengage the limiting pin 535 from the adjustment hole 510 of the linkage shaft 51. At this time, the upper steel frame 11 can rotate around the linkage shaft 51. The damping spring 534 generates buffer resistance when the connecting plate 533 is pressed, ensuring smooth angle adjustment. After the angle is selected, the limiting pin 535 automatically inserts into the corresponding adjustment hole 510 under the action of the spring force to complete self-locking. The angle adjustment of the bracket 2 is achieved by loosening the locking bolt. The angle adjustment block 21 slides along the limiting hole 120 of the lower steel frame 12, and the arc groove 210 provides arc positioning. When the Z-shaped upper steel frame 11 is folded, it is embedded in the inner cavity of the lower steel frame 12, saving space. The pipe box 4 is quickly disassembled and assembled with the fixing angle steel 3 by bolts to meet the pipeline maintenance needs.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
