Description

Technical Field

[0001] This invention relates to the field of electromechanical installation auxiliary equipment technology, and in particular to a modular steel structure welding auxiliary device. Background Technology

[0002] With the rapid development of modern architecture and industry, large steel structural components are increasingly used in bridges, factories, stadiums, and other projects. These large steel structural components are typically too large and heavy to be transported or hoisted as a whole in one go, therefore requiring on-site manufacturing and welding in sections. Traditional on-site welding operations for steel structures usually rely on manual labor or simple mechanical equipment for centering, positioning, and supporting the steel structure.

[0003] However, existing technologies have many shortcomings in on-site welding of large steel structures. First, the weight of steel structural components often reaches tens or even hundreds of tons, making it almost impossible to complete the precise alignment and docking by hand. This relies heavily on the lifting and coordination of hoisting equipment. However, due to the size and weight of the steel structural components, the swaying and displacement during the hoisting process are difficult to control precisely, making it difficult to achieve precise alignment of two sections of steel structure in one go.

[0004] Secondly, even if initial docking can be achieved manually and with lifting equipment, slight misalignments and gaps may still exist at the ends of the steel components due to their own deflection and deformation. Furthermore, traditional on-site welding equipment is typically a monolithic structure with single or incomplete combined functions, lacking a modular design concept. This makes the equipment extremely inconvenient to transport, install, and disassemble, and its versatility is poor, making it difficult to adapt to steel components of different sizes and types.

[0005] How to solve the above-mentioned technical problems is the challenge facing this invention. Summary of the Invention

Detailed Implementation

[0022] See Figures 1 to 8 As shown, a modular steel structure welding auxiliary device includes: Two lifting support mechanisms 100 are respectively set up one-to-one with the two sections of steel structure to be welded, and are used to support the steel structure to be welded and support its position adjustment, so as to accurately move the steel structure to be welded to the predetermined position. The docking mechanism 500 is located between the two supporting mechanisms 100 and cooperates with the ends of the two steel structures to be welded to achieve positioning docking, ensuring the precise alignment and stable fixation of the two steel structures before welding. And a synchronous drive mechanism 600, installed between two lifting support mechanisms 100 and connected to the docking mechanism 500, can drive the two steel structures to move towards each other to achieve a smooth and high-precision docking process.

[0023] More preferably, the lifting support mechanism 100 includes: The stabilizing lifting component 200 is installed at one end of the steel structure to be welded and is used for fine vertical adjustment of the steel structure to be welded. The lifting and moving component 300 is located at the bottom of the steel structure to be welded, and works in conjunction with the stabilizing and lifting component 200 to achieve the movement and support of the steel structure to be welded in the horizontal plane. It also includes several auxiliary lifting components 400, which are set on the steel structure to be welded and work in conjunction with the stabilizing lifting components 200 to provide additional support points and mobility, making it particularly suitable for transportation and positioning over long distances or in complex terrain.

[0024] Specifically, the aforementioned components together constitute a fully functional support and movement system. The stabilizing lifting component 200 is primarily responsible for vertical position adjustment, precisely controlling the height of the steel structure to facilitate subsequent docking and welding operations. The lifting and moving component 300 is responsible for horizontal load-bearing and movement; its cooperation with the stabilizing lifting component 200 allows the steel structure to be adjusted omnidirectionally in three-dimensional space. The auxiliary lifting component 400, as an additional support unit, provides extra support and assistance for long-distance movement or fine-tuning in complex terrain, thereby ensuring the stability and safety of the entire movement process.

[0025] Furthermore, the stabilizing lifting assembly 200 includes: Two stabilizing supports 210 are symmetrically arranged to provide basic support for the device; The stabilizing link 220 is located at the top of the stabilizing bracket 210 and is fixedly connected to the two stabilizing brackets 210, and has symmetrical lifting grooves on it. The stabilizing lifting frame includes two lifting slides 230 located in lifting slides, and a lifting connecting frame 240 for connecting the two lifting slides 230. The lifting drive component 250 is fixed on the stabilizing frame 220 and is used to drive the stabilizing lifting frame to perform lifting movements, thereby achieving high-precision vertical positioning of the steel structure to be welded. Two lifting units 260 are installed at the bottom of the lifting slide 230 and cooperate with the lifting and moving assembly 300.

[0026] Specifically, the lifting drive component 250 can be configured as a linear drive component such as an electric rod or a hydraulic rod, or as a lifting structure composed of a moving worm gear or worm wheel, or a transmission lifting structure composed of a chain / pulley or sprocket / belt.

[0027] Furthermore, the aforementioned lifting link 240 can be located directly above or directly below the stabilizing link 220. However, it is generally preferred to place the lifting link 240 directly above the stabilizing link 220. The structural design of the lifting drive component 250 can be selectively chosen based on the positional relationship between the lifting link 240 and the stabilizing link 220.

[0028] Specifically, the system uses a lifting drive component 250 to drive a stabilizing lifting frame to move vertically within a lifting groove, thereby achieving lifting control of the steel structure to be welded. Its working principle involves transmitting driving force to the stabilizing lifting frame via the lifting drive component 250. The stabilizing lifting frame, in turn, is guided by a lifting slide 230 within the lifting groove of the stabilizing connecting frame 220. Finally, the lifting unit 260 provides vertical support and position adjustment for the steel structure. This structure can withstand large vertical loads and provides a stable lifting platform; its precise motion control is key to achieving vertical positioning of the steel structure.

[0029] Furthermore, the lifting and moving component 300 includes: The support base 310 has two sets of movable rollers 320 symmetrically arranged on it to support the steel structure to be welded and provide the foundation's mobility. Two positioning clamps 330 are symmetrically arranged and installed on the top surface of the lifting base 310 via a slide rail structure, and a positioning unit 340 that cooperates with the lifting base 310 is provided on them. Two lifting brackets 350 are symmetrically arranged on both sides of the supporting base 310, and lifting rods that cooperate with the lifting unit 260 are provided on them; in use, two positioning clamps 330 are located on both sides of the steel structure to be welded.

[0030] Furthermore, the positioning unit 340 includes a positioning seat disposed on the positioning clamp 330, and the positioning seat is provided with positioning screws that cooperate with the lifting base 310 to achieve precise locking of the position of the steel structure.

[0031] Preferably, the positioning clamp 330 is provided with a plurality of positioning slide frames and positioning slide rods that cooperate with the docking mechanism 500. The positioning slide frames and positioning slide rods are arranged alternately, and the positioning slide frame in one lifting and moving component 300 slides in cooperation with the positioning slide rod in another lifting and moving component 300 to provide guidance and calibration functions during docking.

[0032] Furthermore, the lifting unit 260 includes: The lifting base frame 261 serves as the load-bearing structure for the remaining components; The lifting winch 262 is installed on the lifting base frame 261. The lifting flexible cloth 263 has one end wound onto the lifting winch 262, and the other end is provided with a lifting cylinder that cooperates with the lifting rod. And a winding drive component 264, which is installed on the lifting base frame 261 and serves as the drive source for the lifting winch 262, is used to drive the lifting flexible cloth 263 to be extended and retracted, thereby realizing the lifting of the lifting rod. The lifting and moving component 300 also includes: The guide frame 360 ​​is installed at the bottom end of the lifting base 310; Two guide carriages 370 are slidably engaged with the stabilizing bracket 210, respectively; Two telescopic carriages 380 are installed on the guide carriage 370 and slide in cooperation with the guide base 360 ​​to form a multi-stage telescopic guide system to adapt to the movement needs of steel structures of different sizes.

[0033] The winding drive component 264 can be a winding transmission structure consisting of a winding motor or a winding motor and a differential gear, or it can be a winding transmission structure consisting of a winding bearing, a winding gear, a stabilizing gear set that cooperates with the winding gear, and a winding drive disc, which is driven by external drive components such as a hand-held electric drill.

[0034] Preferably, the lifting base 261 is also provided with a guide groove that slides in cooperation with the stabilizing support 210.

[0035] Specifically, the movable rollers 320 bear the weight of the steel structure and, through the cooperation of the guide carriages 370 and telescopic carriages 380, enable the steel structure to move smoothly on the horizontal plane. The guide frame 360, guide carriages 370, and telescopic carriages 380 together constitute a telescopic mobile guiding system, designed to adapt to steel structures of different sizes and provide stable guidance during movement. Furthermore, the positioning clamp 330 is mounted on the support base 310 via a slide rail structure, and its positioning unit 340 engages with the support base 310 via positioning screws. Its purpose is to clamp and lock the steel structure horizontally, preventing positional shifts during movement or docking. The staggered cooperation of the positioning frames and positioning rods provides precise guidance and calibration during docking, ensuring accurate alignment of the ends of the two steel structure sections.

[0036] Furthermore, the auxiliary lifting assembly 400 includes: An auxiliary moving seat 410 is provided with a walking unit 411 and has a receiving groove 412.

And a translation base 450, which is rotatably mounted in the receiving groove 412 of the auxiliary transfer base 410 via a rotating shaft. Its top surface is provided with a translation base for welding steel structures, and a translation unit 460 that cooperates with the walking unit 411 is provided on it. In use, the steel structure to be welded can be placed on the translation base of the translation base 450 to achieve fine adjustment and smooth movement of the steel structure in the horizontal direction.

[0037] Preferably, the auxiliary lifting assembly 400 further includes: The anti-tilting base frame 470 is telescopic and is detachably connected to the top of the drop base frame 420; The anti-tilt frame 480 is telescopic, with its top end connected to the anti-tilt base frame 470 and its bottom end equipped with a movable wheel, forming a telescopic auxiliary support structure to increase the stability and anti-tipping capability of the overall device.

[0038] Preferably, the auxiliary shifter 410 is equipped with a leveling hydraulic leg to adapt to uneven ground and ensure stable operation of the device.

[0039] Specifically, the traveling unit 411 can be configured with multiple casters, swivel wheels, or multiple sets of Mecanum wheel assemblies, or it can be configured with a track drive structure. The translation unit 460 can selectively choose the above-mentioned structural design of the traveling unit 411 according to specific requirements.

[0040] Each Mecanum wheel assembly includes a drive motor and one or more Mecanum wheels. These Mecanum wheels are mounted on a hub at a specific angle, typically 45 degrees. By independently controlling the speed and direction of each Mecanum wheel assembly, the device can move in any direction on a plane.

[0041] The tracked drive structure consists of a drive wheel, a driven wheel, and a track. Forward, backward, and turning movements are achieved by controlling the rotation of the tracks on both sides. To achieve multi-directional movement, a steering mechanism can be integrated into the drive wheel of the tracked drive unit, or more flexible steering can be achieved by designing the track unit as a rotatable structure.

[0042] Specifically, the walking unit 411 is responsible for the movement of the entire assembly on the ground. Its optional Mecanum wheel or track drive design aims to give the device flexible horizontal and lateral movement capabilities in a two-dimensional plane, making it particularly suitable for complex and confined working environments. The translation base 450 is mounted in the receiving slot 412 of the auxiliary transfer seat 410 via a pivot, enabling small-range horizontal translation of the steel structure, thus providing precise positional adjustments. The lifting drive 440 drives the drop carriage 430 to move in the drop chute to lift the bottom of the steel structure, thereby assisting in stabilizing the lifting assembly 200. This assembly adapts to uneven ground through leveling hydraulic legs, ensuring its levelness and stability. The anti-tilt base 470 and anti-tilt transfer frame 480 constitute a retractable anti-tipping system, designed to provide additional support points for the device during lifting and movement, thereby preventing tilting due to instability and greatly improving operational safety.

[0043] More preferably, the docking mechanism 500 includes docking assemblies 510 respectively disposed on two steel structures to be welded, the docking assembly 510 comprising: Reference kit 511 is welded onto the steel structure to be welded, serving as a reference point for docking and positioning; The reference docking part 512 is provided with a reference sleeve 513 that mates with the reference kit 511; At least one reference docking groove 514 is formed through the reference docking member 512; And at least one reference docking rod 515, which slides in conjunction with the reference docking groove 514 of another docking assembly 510, to form a centering and calibration structure to ensure that the central axes of the two steel structures are aligned.

[0047] Specifically, the sliding engagement of the reference docking rod 515 with the reference docking groove 514 of another docking assembly 510 aims to guide the two steel structures to achieve precise centering and axis alignment at their opposite ends, thereby ensuring accurate alignment of the ends of the two steel structures. The engagement of the reference kit 511 and the reference sleeve rod 513 provides a stable reference point for this purpose. This structure plays a crucial role when the two steel structures are about to contact each other; its precise mechanical fit can eliminate minor deviations caused by coarse adjustment, thus creating ideal alignment conditions for subsequent welding work.

[0048] More preferably, the synchronous drive mechanism 600 includes: Two positioning bases 610 are respectively disposed on the reference docking part 512; A horizontally positioned crossbeam 620 is installed between two docking components 510 and has a drive placement slot 630 on it.

[0053] Preferably, the two structures described above are combined.

[0054] Specifically, the synchronous drive mechanism 600, as the final drive part of the entire device, is responsible for precisely pulling the two steel structures closer together to achieve docking. In the first winch-type drive structure, the opposing drive unit 660-4 drives two drive winches 660-3 through the drive shaft 660-2. By winding the drive rope, the hooks of the drive connector 660-1 connected to the reference docking part 512 move towards each other, thereby controlling the opposing movement of the steel structures. In the second screw-type drive structure, the drive screw 6603 with reverse threads, when rotating, simultaneously drives the first slide 6601 and the second slide 6602 to move towards each other. This movement is transmitted to the drive connector 660-1 through the first connecting rod 6604 and the second connecting rod 6605, thereby driving the two steel structures to approach precisely.
