Description

Technical Field

[0001] This utility model relates to the field of welding platform technology, specifically a steel arch frame assembly welding platform. Background Technology

[0002] Steel arch frames are key structural support components used in geotechnical and underground engineering. Leveraging the mechanical properties of high-strength steel, they provide stable load-bearing support for excavated spaces. Typically constructed from welded or cold-bent steel sections, they form an arched structure with a specific curvature. Through close contact with the surrounding rock, they evenly transfer the load of the soil and rock mass to the foundation, effectively suppressing rock deformation, preventing collapse, and ensuring structural safety during construction and operation. In tunnel excavation, mine roadway support, and underground utility tunnel construction, steel arch frames can be flexibly adjusted in cross-sectional dimensions and spacing according to engineering geological conditions. Combined with anchor bolts, shotcrete, and other support measures, they form a composite support system, further enhancing the overall stability of the structure.

[0003] During the use of steel arch frame assembly and welding platforms, the corresponding arc-shaped support blocks need to be frequently replaced to ensure positioning accuracy for processing arc-shaped segments with different radii of curvature. However, traditional platforms often use bolts or welding to connect the arc-shaped support blocks to the platform. Replacing these blocks requires the use of wrenches and other tools to disassemble the fasteners one by one, which is cumbersome and time-consuming. More importantly, bolt fastening is prone to thread stripping after repeated disassembly, leading to a decrease in the positional accuracy of the support blocks after installation, and failing to provide a stable positioning reference for the arc-shaped segments.

[0028] A preferred embodiment of the steel arch frame assembly and welding platform provided by this utility model is as follows: Figure 1-5 As shown: A steel arch frame assembly and welding platform includes: a base 1, with anchor bolts 2 fixedly installed on the bottom of the base 1;

[0029] Fixing component 3 is set on top of base 1;

[0030] The fixing component 3 includes a movable part 31 and a fixed part 32, both of which are located on the top of the base 1.

[0031] The moving part 31 includes a dual-axis motor 311, which is fixedly installed on the top of the base 1. A guide rail 312 is fixedly installed on the top of the base 1. A threaded rod 313 is fixedly installed on the output end of the dual-axis motor 311. A slide block 314 is slidably installed on the top of the guide rail 312. A threaded seat 315 is fixedly installed on the bottom of the slide block 314. The threaded rod 313 is rotatably installed inside the base 1. The threaded rod 313 and the threaded seat 315 are connected by a threaded connection.

[0032] The fixing part 32 includes a mounting base 321, which is located on the top of the base 1. Clamping plates 322 are movably mounted on both sides of the top of the mounting base 321. A rubber pad 323 is fixedly mounted on one side of each clamping plate 322. A double-threaded rod 324 is rotatably mounted on the bottom of the clamping plate 322 via a thread. A motor 325 is fixedly mounted on one end of the double-threaded rod 324. A locking block 326 is fixedly mounted on one side of the mounting base 321. A locking rod 327 is provided inside the locking block 326. A magnet is fixedly mounted on the bottom of the locking rod 327. Block 328, magnetic block 329 is attached to the bottom of magnetic block 328, mounting base 321 is movably mounted on top of slide 314, locking block 326 is movably mounted inside slide 314, bidirectional threaded rod 324 is rotatably mounted inside mounting base 321, motor 325 is fixedly mounted between mounting base 321, the bottom end of locking rod 327 passes through slide 314 and locking block 326 in sequence, and the bottom end of locking rod 327 extends into the interior of slide 314, magnetic block 329 is fixedly mounted inside slide 314;

[0033] The base 1 is made of 20mm thick wear-resistant steel plate with a surface hardness ≥HRC45. It is precision ground to ensure a flatness of ≤0.5mm / m, which can reduce surface damage caused by welding spatter.

[0034] Place the main steel reinforcement of the steel arch frame on the top of the base 1, start the dual-axis motor 311, rotate the threaded rod 313, and move the slide block 314 towards both ends of the main steel reinforcement of the steel arch frame, so that both ends of the main steel reinforcement of the steel arch frame are placed between the clamping plates 322.

[0036] Example 2

[0037] Based on Example 1, a preferred embodiment of the steel arch frame assembly and welding platform provided by this utility model is as follows: Figure 1-5 As shown: Module component 4, which is set on top of base 1;

[0038] The module component 4 includes a lifting part 41 and a module part 42, both of which are located on the top of the base 1.

[0039] The lifting part 41 includes a telescopic rod 411, which is fixedly installed on the top of the base 1. A vertical rod 412 is fixedly installed on the top of the base 1. A side rod 413 is movably installed inside the vertical rod 412. A connecting seat 414 is fixedly installed at the telescopic end of the telescopic rod 411. The top end of the side rod 413 passes through the vertical rod 412 and extends to the top of the vertical rod 412. A hexagonal column 422 is fixedly installed on one side of the top of the vertical rod 412.

[0040] The module part 42 includes an arc-shaped support block 421, which is set on the top of the base 1. A hexagonal column 422 is movably installed on one side of the arc-shaped support block 421. A top rod 423 is fixedly installed at one end of the hexagonal column 422. A card seat 424 and a baffle 425 are respectively provided at the bottom of the top rod 423. The bottom end of the top rod 423 is snapped into the connecting seat 414. The card seat 424 is fixedly installed with the connecting seat 414. One end of the baffle 425 is rotatably installed with the connecting seat 414. The baffle 425 is snapped into the inside of the card seat 424.

[0041] After the main reinforcement of the steel arch frame is fixed, the telescopic rod 411 can be activated, the connecting seat 414 and the top rod 423 will rise, the side rod 413 will move out of the inside of the upright 412, and the height of the arc support block 421 will change to effectively support the arc section of the steel arch frame, making it convenient for workers to weld on the base 1.

[0042] The arc-shaped support block 421 is precision machined from high-strength aluminum alloy material (such as 6061-T6). Its radius of curvature is consistent with the design value of the arc-shaped section of the steel arch frame to be processed, and the tolerance is controlled within ±0.5mm. The arc-shaped support block 421 is set on the top of the base 1 so that the arc-shaped support block 421 fits against each section of the arc-shaped steel arch frame. The contour of the arc-shaped support block 421 constrains the position of the components, providing a more accurate positioning reference for the arc-shaped section. The number of arc-shaped support blocks 421 on the top of the base 1 can be increased according to the arc-shaped section of the steel arch frame to be processed.

[0043] The bottom end of the push rod 423 is snapped into the connecting seat 414. The baffle 425 is snapped into the inside of the seat 424. The baffle 425 blocks and limits the bottom end of the push rod 423. By rotating the other end of the baffle 425, the baffle 425 can be released from blocking the bottom end of the push rod 423. At this time, the push rod 423 can be moved out of the connecting seat 414. At the same time, the hexagonal column 422 is moved out of the inside of both sides of the arc-shaped support block 421. Then the arc-shaped support block 421 can be disassembled and replaced with an arc-shaped support block 421 with a different radius of curvature in order to process steel arch frames with different radii of curvature.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
