Description

Technical Field

[0002] In steel structure engineering, especially in the welding and assembly of irregularly shaped steel components, these components often have large dimensions, complex cross-sections, and irregular shapes. Traditional steel structure welding auxiliary equipment is mostly designed for standard structures, and suffers from poor adaptability, inconvenient adjustment, and inaccurate positioning when dealing with irregularly shaped components. During the hoisting, flipping, and butt welding of components, a lack of effective attitude control and stable support can easily lead to welding deviations, interface misalignment, and even component deformation, thereby affecting the overall structural safety and construction quality.

[0003] To address the aforementioned issues, several structural flipping frames, positioning support frames, or adjustable bracket devices have been proposed in existing technologies. Some technical solutions have introduced hydraulic control, multi-directional turntables, or rigid limiting components to improve flipping and docking efficiency. However, these solutions are mostly limited to rigid structures or single-angle flipping, lacking the ability to adjust for minute displacements during welding, and are particularly difficult to adapt to subtle posture changes caused by thermal expansion and contraction, stress release of components, or construction vibrations during welding.

With the help of a fine posture adjustment component in the auxiliary adjustment mechanism, it can make multi-degree-of-freedom micro-adjustments to the relative position of the first and second steel components in the horizontal, vertical, or tilt directions. This solves the problem of difficult precise positioning of irregularly shaped components due to their complex shapes, and achieves millisecond-level or even micrometer-level precise docking before welding, which greatly improves welding quality and finished product qualification rate.

[0074] The attitude maintenance component in the auxiliary adjustment mechanism of the present invention, particularly its various replaceable maintenance unit structures, can make close contact with the outer surfaces of the first and second steel components and provide continuous and stable limiting support during the welding operation. This effectively resists component deformation caused by welding heat input, gravity sagging, and external disturbances, ensuring that the relative attitude of the two steel components remains unchanged throughout the welding process, avoiding weld misalignment and stress concentration, and guaranteeing the reliability of the welded connection.

[0075] The airbag compression unit in this invention enables rapid and reliable clamping of steel components, reducing manual intervention. The flexible support assembly provides flexible support for easily deformable components during the flipping process, effectively avoiding component damage and safety risks. The entire flipping and docking process is programmable and controllable, reducing the complexity, repetitiveness, and danger of traditional manual operations, significantly improving the welding preparation efficiency of irregularly shaped steel components, and shortening the overall production cycle.

[0076] The replaceable design of the component-bearing mechanism and the maintaining unit in the auxiliary adjustment mechanism of this invention allows the device to flexibly adapt to irregularly shaped steel components of different sizes, shapes, and weights. In particular, the flexible support cloth can better conform to irregular surfaces, avoiding damage to the workpiece. This design makes it highly versatile and widely applicable, capable of meeting the welding needs of various types and small batches of irregularly shaped steel components.

Through its horizontal arrangement, it provides an annular working area for these units, facilitating the turning and tension adjustment of the sling.

[0105] A first tensioning unit 251 is set at one end of the tensioning round frame 215 near the component bearing mechanism 300, and its extension and retraction direction is vertically set.

[0123] A fixing and limiting component 270 is installed on the support base 100 and abuts against the first steel member to limit its position in the horizontal direction. After the first steel member is flipped or in a specific posture, the fixing and limiting component 270 provides a horizontal position limit for the first steel member, preventing unnecessary displacement during subsequent welding operations and ensuring docking accuracy.

[0133] The storage base 263-4 has one end rotatably connected to the storage slide 263-2, and the winding unit 264 is installed at the other end.

It includes a control drive 263-6 to control the telescopic distance, and its other end has a support inclined frame 263-7 rotatably connected to the storage base frame 263-4. The support inclined frame 263-7 has a storage groove 263-1 that mates with the storage base frame 263-4. Through its telescopic function, the support telescopic rod 263-5 can change the tilt angle of the storage base frame 263-4, thereby adjusting the tension of the flexible fabric and the lifting height, achieving precise flexible support for the steel component. The storage groove 263-1 mates with the storage base frame 263-4 during storage, further optimizing the storage effect.

[0135] The structure of the storage drive module 263-3 is basically the same as that of the tension control component 253-4 mentioned above.

[0136] Preferably, the support base 100 has a lifting and shifting groove that penetrates the support base 100, and the lifting and shifting frame 261 penetrates the support base 100 through the lifting and shifting groove. The design of the lifting and shifting groove allows the lifting and shifting frame 261 to pass through the support base 100, thereby expanding the effective lifting range of the flexible fabric 265, enabling it to support larger steel components, or provide more flexible lifting at specific locations.

[0137] Furthermore, the fixed limiting component 270 includes:

[0138] The limiting base 271 is slidably connected to the supporting base 100 via a slide rail structure;

[0139] The limiting base 272 is vertically arranged on the limiting base 271, and a limiting base plate 273 that abuts against the first steel member is provided on it.

[0140] The first limiting drive component 274 is installed on the support base 100 and serves as the driving component of the limiting base 271;

[0141] A second limiting drive component 275 is mounted on the flipping base 210 and serves as the second driving component of the limiting base 271. The second limiting drive component 275 provides additional driving force and can work in conjunction with the first limiting drive component 274, or drive the limiting base 271 independently under certain conditions, to achieve more precise limiting adjustment and ensure the stability of the limiting base 271 under stress.

[0142] The structure of the first limiting drive component 274 is basically the same as that of the tensioning control component 253-4, and the second limiting drive component 275 is designed with a structure of several electric push rods or hydraulic rods on the tensioning base frame 212 and / or tensioning round frame 215.

[0143] The auxiliary adjustment base frame includes two auxiliary shift frames 410 that are slidably connected to the support base 100 via a slide rail structure, and an auxiliary connecting frame 420 located at the top of the two auxiliary shift frames 410.

[0144] The fine attitude adjustment component 600 includes:

[0145] Two sets of attitude adjustment brackets 610 are respectively installed on the auxiliary moving frame 410. Each set of attitude adjustment brackets 610 includes several attitude adjustment brackets 610 respectively installed on the auxiliary moving frame 410. These attitude adjustment brackets 610 provide an installation base for the fine-tuning winch unit 620, and through their multiple installation positions on the auxiliary moving frame 410, they can apply tension or support force to the steel component at multiple points, thereby controlling its attitude more precisely.

[0146] Two sets of fine-tuning winch units 620 are respectively installed on the auxiliary moving frame 410 and are arranged one-to-one with the attitude adjustment bracket 610. Each winch unit is equipped with a fine-tuning rope that is quickly and reliably connected to the fine-tuning base frame pre-installed on the first steel component. The winch unit applies extremely small tension or releases tension on the first steel component by winding and unwinding the fine-tuning rope. In conjunction with the preset fine-tuning base frame, it can achieve precise attitude adjustment of the first steel component in the horizontal, vertical or inclined directions at the millisecond or even micrometer level to meet the stringent butt welding requirements before welding.

[0147] Furthermore, the attitude maintenance component 700 includes:

[0148] The maintaining slide 710 has two ends that are vertically slidably engaged with the auxiliary transfer frame 410, and the maintaining slide 710 is powered along its length by a linear drive 720 mounted on the auxiliary transfer frame 410. The maintaining slide 710 can slide vertically on the auxiliary transfer frame 410, and its movement is controlled by the linear drive 720, such as a linear motor or ball screw. Thus, the maintaining unit 730 can be precisely moved to the part that needs support according to the height and position of the steel component.

[0149] A holding unit 730 is alternatively mounted on the holding carriage 710. The holding unit 730 contacts the outer surfaces of the first and second steel components and serves as a support component that provides limiting support for the relative posture between the steel components during welding operations. The holding unit 730 is a component that directly contacts and supports the steel components. Its replaceable design allows for the selection of the most suitable contact surface and support structure according to different steel component shapes, sizes, and welding requirements. This effectively resists displacement caused by thermal deformation, gravity, and other factors during welding, ensuring that the relative posture of the two steel components remains constant.

[0150] Preferably, the fine-tuning winch unit 620 includes a winch support, a winch, a fine-tuning rope wound on the winch, and an electric drive unit for driving the winch to perform a winding action.

[0151] Preferably, the fine-tuning rope is made of a high-strength, low-elongation material.

[0152] Preferably, the attitude adjustment bracket 610 is provided with a rotating unit for controlling the rotation of the fine-tuning winch unit 620, and the rotating unit can be configured as a simple rotating shaft and a simple rotating structure of a rotating motor.

[0153] Specifically, by tightening or loosening the fine-tuning rope, tension is applied to the first steel component or tension is released, thereby allowing the first steel component to make multi-degree-of-freedom minor adjustments relative to the second steel component in the horizontal, vertical, or inclined directions, so as to achieve precise docking of the two steel components before welding.

[0154] Two preferred structures for the sustaining unit 730 are provided, as follows:

[0155] Firstly, the maintaining unit 730 includes:

[0156] A support frame 741 is fixedly mounted on the support slide 710 by bolts;

[0157] The system includes a positioning and holding bracket 742, which is fixedly connected to the supporting frame 741 via a detachable module. The bracket has a contact surface with the first steel member and a contact surface with the second steel member, and also includes an abutting support portion that abuts against the connection between the first and second steel members. The positioning and holding bracket 742 is a component that directly contacts both steel members. Its integrated design allows it to contact both steel members simultaneously, and the abutting support portion provides support and limitation at the connection, effectively preventing changes in the relative position of the two components during welding. The detachable module design facilitates replacement and maintenance.

[0158] Secondly, the maintaining unit 730 includes:

[0159] A base frame 750 is fixedly mounted on the support slide 710 via a disassembly module;

[0160] The first support frame 751 has one end rotatably connected to the support base frame 750, and the other end is provided with a first angle module 752 that cooperates with the first steel member.

[0161] The second support frame 753 has one end rotatably connected to the support base frame 750, and the other end is provided with a second angle module 754 that cooperates with the second steel member;

[0162] And a retaining module 755, which is installed between the first retainer 751 and the second retainer 753, and serves as a retaining component for maintaining the angle between the first retainer 751 and the second retainer 753.

[0163] Furthermore, the first angle module 752 includes:

[0164] An angle plate has a contact surface that abuts against the first steel member and a hinge portion that is rotatably connected to the first support frame 751. The angle plate is a component that directly contacts the steel member. Its contact surface is optimized to provide stable contact and support, while the hinge portion allows the angle plate to rotate relative to the first support frame 751 to adapt to the surface of the steel member at different angles.

[0165] An angle adjustment component is provided on the first support frame 751 and serves as an angle control structure for the relative position of the angle plate with respect to the first support frame 751. The angle adjustment component, such as a worm gear or lead screw, can precisely control the rotation angle of the angle plate, thereby achieving fine adjustment of the contact angle of the steel component and ensuring the best support effect.

[0166] The structure of the second angle module 754 is the same as that of the first angle module 752.

[0167] Furthermore, the maintaining component includes:

[0168] The support frame 755-1 is fixedly installed on the support base 750 by disassembly module; the support frame 755-1 serves as a frame to support the two control rods, ensuring that they can be stably installed on the support base 750 and withstand the force applied by the control rods.

[0169] The first regulating pole 755-2 is fixedly connected to the support frame 755-1 and the first support frame 751 at its two ends, respectively. Through its telescopic function, the first regulating pole 755-2 can change the distance and angle between the first support frame 751 and the support frame 755-1, thereby achieving further fine-tuning of the support posture of the first steel component.

[0170] The second regulating pole 755-3 is fixedly connected at both ends to the support frame 755-1 and the second support frame 753, respectively. The second regulating pole 755-3 works in conjunction with the first regulating pole 755-2 to precisely control the angle and position of the first support frame 751, thereby finely adjusting the support posture of the second steel component.

[0171] In addition, the component bearing mechanism 300 is mainly responsible for the stable placement of the second steel component. It is usually designed with an adjustable support surface or clamping device to accommodate second steel components of different sizes and shapes, and to ensure that its position is fixed and the force is uniform during the welding process.

[0172] Preferably, the component bearing mechanism 300 includes a bearing base fixedly disposed at the other end of the support base 100; and at least one support fixture installed on the bearing base and used to bear and fix the second steel component.

[0173] The supporting fixture is preferably a height-adjustable support column with a rotatable cap at the top. The cap has multiple limiting slots for placing second steel components of different cross-sectional shapes, or it can be customized according to the specific shape of the second steel component. The support column is height-adjustable via a built-in lifting drive (such as a lead screw drive, hydraulic cylinder, or electric push rod) to accommodate second steel components of different heights. Furthermore, the supporting fixture may also include a lateral limiting mechanism, which clamps or abuts against the second steel component to limit its horizontal position from the side, ensuring that it does not shift during welding.

[0174] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
