Description

Technical Field

[0001] This utility model belongs to the field of steel structure welding technology, and in particular relates to a gantry structure for steel structure welding. Background Technology

[0002] Gantry welding machines are a common type of welding machine, typically used for welding large-volume and long workpieces. Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel profiles and steel plates, and uses rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets.

[0003] Chinese utility model patent CN216126729U discloses a gantry structure for steel structure welding, comprising a guide rail, a protective bracket, a lead screw, and a protective plate. A sliding base is slidably connected to the top of the guide rail, and a support column is mounted on the top of the sliding base. A crossbeam is bolted to the top of the support column, and a sliding bracket is slidably connected inside the crossbeam. An electro-hydraulic push rod is bolted to one side of the crossbeam, and the output end of the electro-hydraulic push rod is bolted to the sliding bracket. A cylinder is mounted at the bottom of the sliding bracket, and the output end of the cylinder is bolted to a welding head. This utility model, a gantry structure for steel structure welding, has a simple and reasonable structure, is easy and convenient to operate, and provides good protection and stability, making it suitable for widespread promotion and use.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] First, the above-mentioned device only has one welding head. When there is a large amount of steel material to be welded, the workload of the welding head of the above-mentioned device is large, and the lateral position of the welding head needs to be adjusted frequently. Therefore, in actual use, it will greatly affect the welding efficiency and increase the working time of the equipment. Utility Model Content

[0006] This utility model provides a gantry structure for steel structure welding, which aims to solve the problem mentioned in the background art that the above-mentioned device only has one welding head. When a large number of steel materials need to be welded at the same time, the welding head needs to be frequently adjusted in its lateral position, which also increases the workload of the welding head, prolongs the working time and reduces the processing efficiency.

[0007] This utility model is implemented as follows: a gantry structure for steel structure welding includes: a mounting frame with a mounting groove on its side wall; an adjustment mechanism having: a first adjustment component movably mounted in the mounting groove, with multiple welding fixtures arranged side by side at equal intervals on the first adjustment component; a second adjustment component movably connecting each welding fixture to the first adjustment component; and support columns fixedly mounted on opposite side walls of the mounting frame; and a transverse movement mechanism movably connected to the support columns on both sides and used to drive the mounting frame to move horizontally. In this solution, multiple welding fixtures are provided in the device. When the device needs to weld multiple steel materials simultaneously, the first adjustment component can be used to move each welding fixture to its corresponding designated position, and then the second adjustment component can be used to fine-tune the designated welding fixture to a preset position (i.e., move the welding fixture to a preset welding position between two adjacent steel materials). Thus, on the one hand, the working efficiency of the device can be improved by using multiple welding fixtures, and on the other hand, the equipment does not need to work for a long time, allowing for rapid welding of a large number of steel materials.

[0008] Preferably, the first adjustment component includes: a rotating shaft rotatably connected to the mounting groove, a plurality of threaded segments equally spaced on the outer wall of the rotating shaft, a movable block screwed onto each threaded segment, and the movable block and the mounting groove slidingly engaged; a first motor fixedly connected to the side wall of one side of the mounting bracket, the output end of which is fixedly connected to one side end of the rotating shaft; one end of each movable block extends to the outside of the mounting groove, and a second adjustment component is fixedly connected to its bottom wall; in this scheme, when the output end of the first motor rotates, it drives the rotating shaft fixedly connected to it to rotate in the mounting groove, and at the same time, the plurality of threaded segments on the outer wall of the rotating shaft drive the movable blocks screwed to them to move horizontally in the mounting groove, thereby synchronously adjusting the horizontal movement of multiple welding fixtures and adjusting the position of multiple welding fixtures.

[0009] Preferably, the second adjustment component includes: a mounting block is vertically fixed to the bottom wall of each of the movable blocks, and a mounting plate is vertically fixed to the bottom wall of each mounting block. Two rotating plates are symmetrically fixed to the bottom wall of the mounting plate, and a first screw is rotatably connected between the two rotating plates. An adjustment seat is threaded onto the first screw, and the top end of the adjustment seat extends into a guide groove on the bottom wall of the mounting plate and slides with the guide groove. A drive component is also fixedly installed on the mounting plate, and the drive component is movably connected to the first screw. In this configuration, after the first adjustment component moves the welding fixture horizontally to the approximate welding position, the drive component controls the rotation of the first screw. The first screw controls the adjustment seat threaded to it to drive the welding fixture to make a fine adjustment of its lateral position, so that the welding fixture is positioned between the two adjacent steel materials to be welded, facilitating subsequent stable welding processing.

[0010] Preferably, the drive assembly includes: a second motor fixedly mounted on the mounting plate, with a drive gear fixedly mounted on its output end, and a driven gear fixedly connected to the outer wall of the first screw, the drive gear and the driven gear meshing together; in this scheme, when the output end of the second motor rotates, it drives the drive gear fixedly connected thereto to rotate, the drive gear controls the driven gear meshing with it to rotate, and since the driven gear is fixedly mounted on the outer wall of the first screw, it drives the first screw to rotate, thereby adjusting the position of the welding fixture using the adjusting seat.

[0011] Preferably, the welding fixture includes: an electric push rod fixedly connected to the bottom wall of the adjusting seat, with a welding machine body fixedly installed on its output end; in this scheme, the extension and retraction of the output end of the electric push rod can drive the welding machine body to rise and fall, so that the welding head of the welding machine body contacts the position to be welded between two adjacent steel materials, thereby achieving stable welding between the two adjacent steel materials by using the drive of the subsequent transverse mechanism.

[0012] Preferably, the lateral movement mechanism includes: two symmetrically arranged connecting seats, each with a moving groove on its top wall; the bottom end of each receiving column is slidably connected to the corresponding moving groove; a second screw is rotatably connected to one moving groove, and the bottom end of the receiving column on that side is screwed into the second screw; a third motor is fixedly connected to the outer wall of the connecting seat, its output end being fixedly connected to the end of the second screw; a sliding rod is fixedly connected to the moving groove on the other side, and the bottom end of the receiving column on that side is slidably connected to the sliding rod. In this scheme, when the output end of the third motor rotates, it drives the second screw to rotate. The second screw controls the receiving column screwed to it to move laterally along the moving groove. At the same time, the receiving column on that side is guided and limited by the other receiving column and the sliding rod to drive the mounting frame to move laterally, thereby controlling multiple welding fixtures to move horizontally and realizing the welding processing between steel materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a gantry structure for steel structure welding:

[0014] 1. This device is equipped with multiple welding fixtures. When this device needs to weld multiple steel materials at the same time, the first adjustment component can be used to move each welding fixture to the corresponding designated position, and then the second adjustment component can be used to fine-tune the designated welding fixture to the preset position (that is, move the welding fixture to the preset welding position between two adjacent steel materials). In this way, on the one hand, the working efficiency of this device can be improved by using multiple welding fixtures, and on the other hand, the equipment does not need to work for a long time, and a large number of steel materials can be welded quickly.

[0036] Working principle and usage process of this utility model:

[0037] Multiple steel materials to be welded are placed between two connecting seats 31. Then, the output end of the first motor 214 controls the rotating shaft 211 to rotate. The rotating shaft 211 rotates and uses the threaded section 212 on its outer wall to control multiple moving blocks 213 to move laterally in the mounting groove 11. When the welding machine body 222 moves to the approximate position, the first screw 234 is driven to rotate by the meshing between the second motor 241, the driving gear 242 and the driven gear 243. The first screw 234 is used to control the adjusting seat 235 to move laterally, so as to finely adjust the position of the welding machine body 222.

[0038] After adjustment, the third motor 34 controls the second screw 33 to rotate, and the second screw 33 and the sliding rod 35 work together to drive the mounting frame 1 to move laterally, and work with the welding machine body 222 to weld the steel material.
