Description

Technical Field

[0001] This utility model belongs to the field of submerged arc trolley track technology, specifically relating to a variable track segmented track device for traditional submerged arc trolley welding. Background Technology

[0002] In the steel structure manufacturing process, especially during on-site installation, the use of submerged arc welding (SAW) trolleys can maximize the welding quality of butt welds. Currently, the temporary tracks of traditional SAW trolleys are mostly segmented straight tracks. For butt welds of steel box girders at angled bends, the straight track must be completely parallel to the weld. However, traditional SAW trolleys lack automatic weld recognition functionality, resulting in an angular deviation between the welding torch trajectory and the actual weld, affecting welding quality and efficiency.

[0003] Currently, traditional submerged arc welding (SAW) trolley tracks used in steel structure production can only achieve straight welding trajectories. However, for submerged arc welding of irregularly shaped steel structures, traditional SAW trolleys cannot perform welding operations on curved welds. Therefore, this technical solution proposes a variable-track segmented track device for welding with traditional SAW trolleys. Utility Model Content

[0004] The purpose of this invention is to provide a variable-track segmented track device for traditional submerged arc welding trolleys. This device can provide a straight track or a curved track for the traditional submerged arc welding trolley, assisting it in welding curved or non-straight welds, maintaining a relatively smooth welding trajectory, reducing weld breakage during the welding process, and improving welding quality and efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A variable-track segmented track device for traditional submerged arc welding trolley includes at least two track units, with adjacent track units connected by an adjustable docking unit to achieve direct docking and misaligned docking of adjacent track units.

[0007] The track unit includes a track base, on which two parallel track bodies are fixedly connected, and at least a portion of the track bodies at both ends gradually decrease in width.

[0008] Furthermore, the track body includes a track main body fixedly connected to the upper side of the track base. Both ends of the track main body are fixedly connected to narrow track bodies, and the central axes of the two narrow track bodies are staggered. An arc-shaped surface is provided at the end of the track main body near the narrow track body, and the two ends of the arc-shaped surface are respectively connected to the side of the track main body and the narrow track body.

[0009] Furthermore, a connector is fixedly connected to one end of the track base, and two docking points adapted to the connector are provided at the other end of the track base. The connector and any one of the docking points are fixedly connected, and the connector and the docking points form an adjustable docking unit.

[0010] Furthermore, the connector is a round-headed locking block fixedly connected to one end of the track base, and the docking point is a slot opened at the other end of the track base, and the round-headed locking block can be locked inside the slot.

[0011] Furthermore, the track base includes two track supports, a connecting frame is fixedly connected between the two track supports, the two track bodies are respectively fixedly connected to the two track supports, the joint is fixedly connected to one end of the track support, and the docking point is opened at the other end of the track support.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a variable-track segmented track device for traditional submerged arc welding carriages. By adjusting the docking position of two adjacent track units, it can provide a straight track or a curved track for the traditional submerged arc welding carriage, ensuring that the welding trajectory of the traditional submerged arc welding carriage matches the non-linear weld bead. When performing submerged arc welding on irregularly shaped or non-linear steel structures, it can assist the traditional submerged arc welding carriage in achieving curved weld operations. Not only can it maintain a straight welding operation, but it can also maintain a relatively smooth welding trajectory when welding curved or non-linear welds, reducing weld breakage during the welding process and improving welding quality and efficiency.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-6 As shown, a variable-track segmented track device for traditional submerged arc welding trolleys includes at least two track units, with adjacent track units connected by an adjustable docking unit.

[0024] The track unit includes a track base, on which two parallel track bodies are fixedly connected. At least a portion of the width of the track bodies at both ends gradually decreases, so that when the track units are misaligned, the buried arc trolley can smoothly travel to the next track section.

[0025] The track body includes a track body 3 fixedly connected to the upper side of the track base. Both ends of the track body 3 are fixedly connected to narrow track rails 4, and the central axes of the two narrow track rails 4 are staggered.

[0026] It should be noted that an arc-shaped surface 5 is provided at the end of the track body 3 near the narrow track body 4. The two ends of the arc-shaped surface 5 are respectively connected to the side of one side of the track body 3 and the narrow track body 4, and the other side of the track body 3 and the narrow track body 4 are directly connected.

[0027] In use, the adjustable docking unit can adjust the horizontal docking position between the two track units, thereby adjusting the relative position of the narrow rail body 4 of the two track units;

[0028] like Figures 1-4 As shown, when the central axes of the two track units 3 are opposite each other, the two track units are directly connected, and the segmented track formed by splicing is a straight welding mode. The traditional submerged arc trolley moving on the segmented track can move in a straight line, and the weld is a straight line, which ensures the straight welding stability of the traditional submerged arc trolley.

[0029] like Figures 1-2 and Figure 5As shown, when the central axes of the two track units 3 are misaligned and the central axes of the narrow track 4 are opposite, the two track units are misaligned and joined together to form a segmented track with a curved welding mode. When the traditional submerged arc trolley moves on the track body 3, it can move in a straight line. However, since the central axes of the two track units 3 are not a straight line, there is a certain distance deviation, which causes the submerged arc trolley to shift laterally, thereby realizing the trajectory movement of the welding torch. When the traditional submerged arc trolley passes through the arc surface 5, it can move in a curved direction, thus enabling butt welding of structures with curved surfaces, such as butt welding of steel box girders at turns with a certain angle.

[0030] One end of the track base is fixedly connected to a connector 6, and the other end of the track base is provided with two docking points 7 that are compatible with the connector 6. The connector 6 and any one of the docking points 7 are fixedly connected, so that the connector 6 and the docking point 7 form an adjustable docking unit to achieve the direct docking or misaligned docking of the two track bases.

[0031] The fixing connection method between the connector 6 and the mating point 7 can be magnetic connection, snap-fit ​​connection or screw connection;

[0032] like Figure 6 As shown, in some embodiments, the connector 6 is a round-headed locking block fixedly connected to one end of the track base, and the docking point 7 is a slot opened at the other end of the track base. The round-headed locking block can be locked inside the slot to realize the locking and fixing of the two track bases.

[0033] It should be noted that the lower end of the slot is open, allowing the round-headed locking block to directly enter the slot from the lower end, thus making it relatively easy to connect the connector 6 and the mating point 7.

[0034] Specifically, the round-headed locking block is a combination structure of a round rod and a round plate.

[0035] like Figure 1 As shown, in some embodiments, the track base includes two track supports 1, and a connecting frame 2 is fixedly connected between the two track supports 1. The connecting frame 2 is preferably an angle steel to realize a hard connection between the two track supports 1, thereby improving the stability of the track supports 1. Two track bodies 3 are respectively fixedly connected to the two track supports 1. The butt joint 6 is fixedly connected to one end of the track support 1, and the docking point 7 is opened at the other end of the track support 1.

[0036] It should be noted that the main body of the track 3 and the narrow rail body 4 are directly welded to the upper side of the track support 1, so that the main body of the track 3, the narrow rail body 4 and the track support 1 are tightly connected.

[0037] The main track body 3 and the narrow track body 4 can be made of lightweight and strong materials, such as aluminum alloy or other high-strength metal materials, which combine durability and flexibility to ensure sufficient strength and durability during the movement of the submerged arc trolley.

[0038] The working principle of this utility model is as follows:

[0039] When using it, first clean the debris and slag on both sides of the weld to ensure the flatness of the track. Observe whether the weld is a straight weld or a curved weld. According to the actual needs, connect the joint 6 and the docking point 7 of the two track units to meet the requirements of straight welding or curved welding, which is highly flexible.

[0040] In summary, this technical solution, by adjusting the docking position of two adjacent track units, can provide a straight or curved track for the traditional submerged arc welding (SAW) trolley, ensuring that the welding trajectory of the SAW trolley matches the non-linear weld bead. When performing SAW welding on irregularly shaped or non-linear steel structures, it can assist the traditional SAW trolley in achieving curved weld operations. This not only allows the traditional SAW trolley to maintain straight welding operations but also maintains a relatively smooth welding trajectory when welding curved or non-linear welds, reducing weld interruptions and improving welding quality and efficiency. Its material and structural design also fully considers durability and applicability to adapt to the needs of different construction environments.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
