Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a positioning and welding equipment for precast steel structure components used in building construction. Background Technology

[0002] In the construction of prefabricated buildings, the on-site connection and welding of precast steel components are key aspects affecting construction efficiency and structural safety. Traditionally, the connection of precast steel components is often carried out manually with the help of hoisting equipment for positioning and spot welding, followed by manual hand-held welding torches to complete the circumferential welding. This method suffers from problems such as poor positioning accuracy, misalignment and uneven gaps in the connection section, and unstable welding quality.

[0003] While existing welding equipment for precast steel structures can achieve a certain degree of automated welding, it still has many technical shortcomings: Most equipment only has a single welding function and cannot pre-treat rust, scale, debris and uneven parts of the steel precast component section before welding. Poor cleanliness and flatness of the section can easily lead to defects such as porosity, slag inclusion and lack of fusion during the welding process, reducing the weld strength and service life of the structure. The positioning and walking mechanism of the equipment on the steel precast components is simple in design and lacks a reliable clamping positioning and automatic walking switching structure. It is easy to loosen and deviate during positioning, and it is easy to slip due to water and debris on the surface of the steel precast components during walking, resulting in poor equipment operation stability. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning and welding device for precast steel structures used in building construction, which aims to solve the technical problems existing in the prior art mentioned in the background.

The annular sleeve is rotatably connected to the surface of the annular mounting frame, and the side wall of the annular sleeve meshes with the drive worm. The first gear is rotatably connected inside the annular mounting frame. One side of the grinding plate is fixedly connected to the first gear. The first toothed plate is located on the inner wall of the annular sleeve, and the first gear meshes with the first toothed plate. The positioning component, located inside the base, helps the base remain stable during welding and propels it forward on the precast steel structure after welding.

[0006] As a preferred technical solution of the present invention: a first spring is fixedly connected between the side of the arc-shaped protective box near the axis of the annular mounting frame and the inner wall of the annular mounting frame; an opening is provided on the side of the arc-shaped protective box near the axis of the annular mounting frame, the opening angle of which is equal to the rotation angle of the welding torch; an energy storage tank is fixedly connected to the outer wall of the annular mounting frame, and the energy storage tank is in communication with the welding torch.

[0007] As another preferred technical solution of the present invention: the surface of the arc-shaped protective box is arc-shaped, the outer wall of the arc-shaped protective box is in contact with the surface of the steel precast component, the welding torch is equipped with an image processing device for detecting the weld width of the steel precast component, and the image processing device electrically controls the welding torch to rotate in the arc-shaped protective box.

[0008] As another preferred technical solution of the present invention: the width of the grinding plate is equal to the wall thickness of the annular mounting bracket, and the surface of the grinding plate is provided with a sand grinding disc, and the image processing equipment in the welding gun electrically controls the start and stop of the worm gear.

[0009] As another preferred technical solution of the present invention: drive wheels are uniformly installed at the bottom of the base, the drive wheels slide in contact with the upper surface of the steel prefabricated component, and a drainage roller is installed on the forward direction side of the bottom of the base, the rotation speed of the drainage roller is five times that of the drive wheel.

[0010] As another preferred technical solution of the present invention: a traction rope is wound on the traction machine, and the traction rope is fixedly connected to the front end of the top of the base.

[0011] As another preferred technical solution of the present invention: the positioning component includes a slide rail slidably connected inside the side support plate, an electric drive shaft is installed on the side of the slide rail away from the side support plate, a first clamping plate is fixedly connected to the electric drive shaft, a bracket is uniformly rotatably connected inside the first clamping plate, a second gear is fixedly connected to the middle of the bracket, longitudinal rollers are rotatably connected to both ends of the bracket, angled positioning plates are symmetrically fixedly connected to the outer wall of the first clamping plate, the side wall of the bracket is in contact with the surface of the angled positioning plates, a second toothed plate is slidably connected inside the first clamping plate, a second spring is fixedly connected between the end side of the second toothed plate and the inner wall of the first clamping plate, the surface of the second toothed plate meshes with the second gear, a transverse roller is rotatably connected to the side of the first clamping plate near the steel precast component, and a second clamping plate is slidably connected inside the side support plate and below the slide rail.

[0013] The beneficial effects of this invention are as follows: The rotating ring-shaped mounting frame, driven by a drive gear, allows the welding torch to travel in a ring along the cross-section of the precast steel structure. Combined with intelligent image processing control of the welding torch angle rotation, continuous, stable, and uniform ring welding can be achieved on the angled and irregularly shaped cross-sections of the precast steel structure, effectively avoiding problems such as incomplete welding, false welding, and uneven weld formation, significantly improving the automation level and welding quality. Before welding, the grinding component automatically grinds the steel structure cross-section to remove rust, scale, oil, and debris, resulting in a smooth, clean surface that exposes the metal's natural color. This significantly reduces welding defects such as porosity, slag inclusions, and lack of fusion, ensuring welding penetration and fusion effect, and significantly improving the joint's mechanical properties and structural safety. The equipment comes with drive wheels and positioning components, enabling a cyclical operation of positioning welding—unlocking movement—repositioning welding on the steel structure, eliminating the need for repeated hoisting and disassembly, greatly improving construction efficiency. It is particularly suitable for on-site construction of long-distance, multi-node precast steel structures. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0018] like Figures 1 to 9 As shown, in one embodiment, a positioning and welding device for precast steel structure components in building construction is proposed, including a base 1, a telescopic cylinder 2, a traction machine 3, and side support plates 4. The telescopic cylinder 2 is installed between two bases 1, the traction machine 3 is installed on top of the two bases 1, and the side support plates 4 are symmetrically installed on both sides of the base 1. The device also includes: Welding assembly 5, set on base 1, is used for circumferential welding of the cross-section of precast steel structure components. Welding assembly 5 includes directional chute 51, annular mounting frame 52, drive gear 53, arc-shaped protective box 54, and welding torch 57. The directional chute 51 is opened on the surface of base 1. The annular mounting frame 52 is limited to rotate inside the directional chute 51. The drive gear 53 is mounted on the surface of base 1. The inner wall of the annular mounting frame 52 meshes with the drive gear 53. The arc-shaped protective box 54 is slidably connected to the annular mounting frame 52. The welding torch 57 is rotatably connected to the inside of the arc-shaped protective box 54. Grinding assembly 6 is set on directional slide 51 and is used to grind the cross-section of steel precast component. Grinding assembly 6 includes drive worm 61, annular sleeve 62, first toothed plate 63, grinding plate 64 and first gear 65. Drive worm 61 is mounted on the surface of annular mounting frame 52. Annular sleeve 62 is rotatably connected to the surface of annular mounting frame 52. The side wall of annular sleeve 62 meshes with drive worm 61. First gear 65 is rotatably connected inside annular mounting frame 52. One side of grinding plate 64 is fixedly connected to first gear 65. First toothed plate 63 is set on the inner wall of annular sleeve 62. First gear 65 meshes with first toothed plate 63. Positioning component 7 is located inside base 1 and is used to help base 1 remain stable during welding and to move forward on the steel precast component after welding.

[0019] In practical application, the workers first install the base 1 on the fixed steel precast component. Then, the base 1 will actively advance on the steel precast component. When the base 1 moves to the fixed steel precast component section, the image processing device inside the welding torch 57 will control the device to slow down the advancing speed and stop the base 1 when the section is flush with the welding torch 57. At this time, the section of the steel precast component is in a centered state inside the annular mounting frame 52. After the base 1 is positioned and fixed on the fixed steel precast component, the workers use a crane or other lifting equipment to bring the other steel precast component that needs to be butt welded into contact with the section of the fixed steel precast component. When the sections of the two steel precast components are in contact, the base 1 clamps and positions the two steel precast components through the side support plate 4, and makes their sections fit tightly. Then, the drive gear 53 is energized and drives the annular mounting frame 52 to rotate inside the directional slide groove 51 of the base 1. During the rotation, the annular mounting frame 52 will drive the arc-shaped protective box 54 and the welding torch 57 to rotate together around the butt joint of the steel precast components. At this time, the welding torch 57 will be turned on and the two steel precast components will be connected by laser welding. During the welding process of the welding torch 57 moving around the steel precast components in a ring, the image processing equipment inside the welding torch 57 will analyze the angle position of the steel precast components and ensure the continuity of the welding by making the welding torch 57 rotate inside the arc-shaped protective box 54.

[0020] During the rotation of the annular mounting frame 52, when the arc-shaped protective box 54 moves to an area where the distance between the precast steel component and the inner wall of the annular mounting frame 52 is short, the outer wall of the arc-shaped protective box 54 will press against the surface of the precast steel component. After being compressed, the arc-shaped protective box 54 will slide outward inside the annular mounting frame 52 by causing the first spring 55 to elastically contract. This allows the welding torch 57 to maintain a shorter distance from the precast steel component during the annular welding process, thereby improving welding efficiency.

[0021] Before the welding process begins and the two precast steel components are joined, the image processing equipment inside the welding torch 57 detects that the precast steel component is located in the middle of the annular mounting frame 52. The image processing equipment first controls the drive worm gear 61 to start and rotate. When the drive worm gear 61 rotates, it meshes and drives the annular sleeve plate 62 to rotate on the outer wall of the annular mounting frame 52. After the annular sleeve plate 62 rotates, the grinding plate 64, which was originally stored inside the annular mounting frame 52, will flip to the middle of the annular mounting frame 52. After the grinding plate 64 flips, the sanding disc on its side wall will fit against the cross-section. At this time, the drive gear 53 drives the annular mounting frame 52 to rotate, which will cause the grinding plate 64 to rotate on the cross-section surface, grinding the cross-section of the precast steel component to remove rust and other stains from its surface, exposing a clean metal surface. At the same time, it ensures the smoothness of the cross-section, ensures that the contact surface can fit efficiently during the joining, makes the arc more stable during welding, and results in a higher level of strength after welding.

[0022] like Figures 3 to 6 As shown, in a preferred embodiment of the present invention, a first spring 55 is fixedly connected between the side of the arc-shaped protective box 54 near the axis of the annular mounting frame 52 and the inner wall of the annular mounting frame 52. An opening 56 is provided on the side of the arc-shaped protective box 54 near the axis of the annular mounting frame 52. The opening angle of the opening 56 is equal to the rotation angle of the welding torch 57. An energy storage tank 58 is fixedly connected to the outer wall of the annular mounting frame 52. The energy storage tank 58 is connected to the welding torch 57.

[0023] In practical application, the welding torch 57 welds the precast steel structure through the arc-shaped protective box 54 via the opening 56. The opening 56 allows the welding torch 57 to weld the precast component while also being protected by the arc-shaped protective box 54.

[0024] like Figure 7 and Figure 8 As shown, in another preferred embodiment of the present invention, the surface of the arc-shaped protective box 54 is arc-shaped, the outer wall of the arc-shaped protective box 54 is in contact with the surface of the steel precast component, and the welding torch 57 is equipped with an image processing device for detecting the weld width of the steel precast component. The image processing device electrically controls the welding torch 57 to rotate in the arc-shaped protective box 54.

[0025] like Figures 7 to 9 As shown, in another preferred embodiment of the present invention, the width of the grinding plate 64 is equal to the wall thickness of the annular mounting bracket 52, and the surface of the grinding plate 64 is provided with a sanding disc. The image processing equipment in the welding torch 57 electrically controls the start and stop of the drive worm gear 61.

[0026] like Figure 1 and Figure 10 As shown, in another preferred embodiment of the present invention, drive wheels 11 are uniformly installed at the bottom of the base 1. The drive wheels 11 slide in contact with the upper surface of the steel precast component. A drainage roller 12 is installed on one side of the bottom of the base 1 in the forward direction. The rotation speed of the drainage roller 12 is five times that of the drive wheel 11.

[0027] In practical application, during the rotation of the drive wheel 11 inside the base 1, it propels the base 1 by rolling on the surface of the precast steel structure, enabling the base 1 to move continuously on the precast steel structure. The high-speed rotation of the drainage roller 12 can discharge the accumulated water on the surface of the precast steel structure to both ends, thereby ensuring that the drive wheel 11 will not slip due to water accumulation when it contacts the precast steel structure, and improving the efficiency of the base 1's movement during propulsion.

[0028] like Figure 1 As shown, in another preferred embodiment of the present invention, a traction rope is wound on the traction machine 3, and the traction rope is fixedly connected to the front end of the top of the base 1.

[0029] In practical application, after the precast steel structure component is hoisted and placed inside the front base 1, the front base 1 clamps and fixes the precast steel structure component. After the hoisting system is unloaded, the front base 1 will bear high pressure. Through the joint support of the telescopic cylinder 2 and the traction machine 3, the bases 1 on both sides can remain flush when welding the precast steel structure component. The telescopic cylinder 2 can adjust the distance between the two bases 1 slightly by telescopic extension, so that the two precast steel structure components can fit tightly together.

[0030] like Figures 10 to 13 As shown, in another preferred embodiment of the present invention, the positioning component 7 includes a slide 71 slidably connected inside the side support plate 4. An electric drive shaft 72 is installed on the side of the slide 71 away from the side support plate 4. A first clamping plate 73 is fixedly connected to the electric drive shaft 72. A bracket 75 is rotatably connected inside the first clamping plate 73. A second gear 77 is fixedly connected to the middle of the bracket 75. Longitudinal rollers 76 are rotatably connected to both ends of the bracket 75. An angled positioning plate 74 is symmetrically fixedly connected to the outer wall of the first clamping plate 73. The side wall of the bracket 75 is in contact with the surface of the angled positioning plate 74. A second toothed plate 78 is slidably connected inside the first clamping plate 73. A second spring 79 is fixedly connected between the end of the second toothed plate 78 and the inner wall of the first clamping plate 73. The surface of the second toothed plate 78 meshes with the second gear 77. A transverse roller 710 is rotatably connected to the side of the first clamping plate 73 near the steel precast component. A second clamping plate 711 is slidably connected inside the side support plate 4 and below the slide 71.

[0031] In practical application, the first clamping plate 73 and the second clamping plate 711 slide in opposite directions inside the side support plate 4 and are positioned inside the precast steel structure by friction, so that the base 1 can maintain a stable state inside the precast steel structure. When the top of the first clamping plate 73 is in contact with the surface of the precast steel structure, the bracket 75 flips to a horizontal state and is stored on both sides of the first clamping plate 73. At this time, the second spring 79 is stretched and is in an elastic extension state.

[0032] When the equipment completes welding of the current section and needs to continue advancing on the precast steel structure for the next section of welding, the slide 71 and the second clamping plate 711 are driven and slide relatively close to each other on the side support plate 4. At this time, the top of the first clamping plate 73 is no longer blocked by the precast steel structure. The stretched second spring 79 elastically contracts and drives the second toothed plate 78 to slide inside the first clamping plate 73. After sliding, the second toothed plate 78 will mesh with the second gear 77, causing the bracket 75 to rotate together with the longitudinal roller 76, so that the bracket 75 rotates to a state perpendicular to the first clamping plate 73. The angle positioning plate 74 limits the rotation angle of the bracket 75. Through the design of the angle positioning plate 74 with a 100-degree angle, the bracket 75 will not rotate back to the sides of the first clamping plate 73 when under pressure. After the bracket 75 rotates, the longitudinal roller 76 will roll on the surface of the precast steel structure, so that the base 1 is in a sliding state on the surface of the precast steel structure.

[0033] When the base 1 needs to be positioned to start welding, the electric drive shaft 72 will first drive the first clamping plate 73 to rotate slightly, so that the angle between the bracket 75 and the steel precast component is less than 90 degrees. Then the slide 71 slides upward in the side support plate 4. After the longitudinal roller 76 is squeezed, it drives the bracket 75 to rotate inside the first clamping plate 73, so that the bracket 75 and the longitudinal roller 76 are repositioned on both sides of the first clamping plate 73, so that the top of the first clamping plate 73 abuts against the surface of the steel precast component, thereby achieving the positioning of the base 1 on the steel precast component.

[0034] like Figures 10 to 13 As shown, in another preferred embodiment of the present invention, the bottom frame of the angle positioning plate 74 is parallel to the bottom of the first clamping plate 73, the angle between the edge of the angle positioning plate 74 and the bottom frame is 100 degrees, the angle positioning plate 74 limits the flipping angle of the bracket 75, and the bracket 75 is perpendicular to the first clamping plate 73 when the second spring 79 is not retracted.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
