Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to a planar steel truss welding equipment. Background Technology

[0002] Steel truss floor decking is a type of unsupported profiled composite floor decking. A steel truss is a truss formed by connecting steel bars as the top chord, bottom chord, and web members via resistance spot welding. A steel truss floor decking is a composite load-bearing slab formed by connecting the steel truss to the base slab via resistance spot welding. This process enables mechanized production, resulting in uniform steel bar spacing and consistent concrete cover thickness, thus improving the construction quality of the floor slab. Therefore, it addresses the issue of limited outdoor installation and use of hammocks, particularly in areas without trees where users cannot use them.

[0003] A patent with patent number 202321254785.6 discloses a planar steel truss welding device, including a processing base and several welding heads. Both sides of the processing base are equipped with slag removal components, each including a filter box and an air suction hopper. A connecting pipe is fixedly connected to the top of the filter box, and a filter screen is installed inside. An air pump is installed at the bottom of the filter box. A through slot is opened on one side of the filter box, and a collection box is fixedly connected to one side. An observation door is hinged to one side of the collection box. The filter box is fixedly connected to one side of the processing base, and a material discharge component is installed inside the filter box. The material discharge component includes a first motor and a mounting rod. The air pump draws particles mixed with air from around the weld into the connecting pipe through the air suction hopper, causing the particles to fall into the filter box. The filter screen intercepts and collects the metal particles, and clean air is discharged through the air pump's outlet, preventing any impact on the respiratory health of workers. However, in this patent, not all fine metal particles in the filter box are intercepted by the filter plug; these particles are discharged by the air pump through the plug holes, failing to achieve the purpose of protecting the respiratory health of workers. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a planar steel truss welding device that filters and cleans the air containing metal particles, thereby protecting the respiratory health of workers.

[0005] In view of this, the present invention provides a planar steel truss welding equipment, characterized in that it includes a workbench, and the workbench is provided with:

[0006] A welding device is provided on a workbench and is used to weld the joints of a steel truss.

[0007] A filter box is fixedly installed on each side of the workbench;

[0008] An air pump is fixedly installed below the filter box. The air pump is used to absorb metal particles generated during the welding of the steel truss into the filter box.

[0009] A filter screen is installed inside the filter box and is used to filter metal particles mixed in the air.

[0010] An adsorption device is slidably disposed inside a filter box and positioned below a filter screen. The adsorption device is used to adsorb metal particles that are not intercepted by the filter screen.

[0011] In this technical solution, when the welding device welds the steel truss, it generates metal particles. The air pump works to suck the metal particles generated during the welding into the filter box, where they are initially cleaned by the filter screen. Meanwhile, metal particles smaller than the diameter of the filter screen holes fall out of the filter screen holes and are adsorbed by the adsorption device for secondary cleaning. The two cleaning processes prevent the metal particles from being directly discharged under the suction of the air pump, thus avoiding air pollution and protecting the health of the workers.

[0012] Furthermore, the adsorption device includes an adsorption component and a driving component. The adsorption component is disposed inside the filter box and rotatably connected to the filter box. The driving component is disposed inside the filter box. The adsorption component and the driving component are fixedly connected. The adsorption component is used to adsorb metal particles, and the driving component is used to drive multiple sets of adsorption components to rotate.

[0013] In this technical solution, the driving component drives multiple adsorption components to rotate, increasing the area of ​​the adsorption surface, which can adsorb more metal particles and extend the service life of the adsorption components.

[0014] Furthermore, the driving component includes:

[0015] A rotating shaft is horizontally mounted on the filter box and passes through the front end of the filter box, rotatably connecting to the filter box.

[0016] The first motor is fixedly installed at the front end of the filter box, and the output end of the first motor is connected to one end of the rotating shaft.

[0017] In this technical solution, the first motor drives the rotating shaft, which in turn drives multiple adsorption components to rotate, thus better adsorbing metal particles in the filter box.

[0018] Furthermore, the adsorption component includes:

[0019] An adsorption plate is disposed inside the filter box and is fixedly positioned along the length of the rotating shaft. The adsorption plate is made of metal.

[0020] A magnet is attached to the top of the adsorption plate.

[0021] In this technical solution, the drive component works to drive the magnets adsorbed on the adsorption plate to rotate. The rotation of the rotating shaft causes the metal particles falling on the rotating shaft to leave the surface of the adsorption shaft and be adsorbed by the magnets. The rotation of the magnets can adsorb the metal particles at a faster speed, preventing the metal particles from being discharged outside the filter box.

[0022] Furthermore, the filter box is provided with a sliding box inside, and an adsorption component is provided inside the sliding box, with the sliding box slidably connected to the filter box.

[0023] In this technical solution, the sliding box can be pulled out of the filter box to replace the magnet on the adsorption component, making replacement convenient.

[0024] Furthermore, a grinding device is provided on the workbench, which is used to grind the joints of the steel truss after welding.

[0025] Furthermore, the grinding device includes a grinding component, a moving component, and a telescopic component. The grinding component is used to grind the unevenness at the joint of the welded steel truss. The moving component is used to drive the grinding component to move left and right. The telescopic component is used to drive the grinding component to move up and down.

[0026] In this technical solution, driven by the moving and telescopic components, the grinding component can move left and right and up and down, enabling it to grind steel truss joints of different sizes, thus making it more practical.

[0027] Furthermore, the moving component is disposed on the worktable, and the moving component includes:

[0028] Side plates, two side plates are respectively set on both sides of the workbench, and the side plates are fixedly connected to the workbench;

[0029] A top plate is disposed at the top of the side plate and is fixedly connected to the side plate;

[0030] The main lead screw is mounted on the side plate and is rotatably connected to the side plate through the side plate.

[0031] The second motor is fixedly mounted on the side wall of the side plate, and the output shaft of the second motor is connected to one end of the main lead screw.

[0032] Mounting plate, which is disposed below the top plate and is provided with slide rail;

[0033] A movable rod is vertically mounted on the main lead screw and threadedly connected to the main lead screw. The movable rod is slidably connected to the mounting plate via a slide rail and is fixedly connected to the grinding assembly.

[0034] In this technical solution, the second motor operates, driving the main lead screw to rotate. The main lead screw drives the moving rod to slide on the mounting plate slide rail, thereby driving the grinding assembly to move left and right.

[0035] Furthermore, the telescopic assembly is disposed on the worktable and includes:

[0036] A side plate, wherein a limiting groove is provided on the side plate, and the limiting groove is slidably connected to the main lead screw in a vertical direction;

[0037] A servo electric cylinder is fixedly mounted on the top plate, and the output end of the servo electric cylinder passes through the top plate and is fixedly connected to the mounting plate.

[0038] In this technical solution, the servo electric cylinder operates, driving the mounting plate to move up and down. The mounting plate then drives the moving rod to move up and down, thereby driving the grinding assembly to move up and down.

[0039] Furthermore, the polishing component includes:

[0040] A grinding wheel, wherein the grinding wheel is disposed below the moving rod and rotatably connected to the moving rod;

[0041] The third motor is fixedly installed inside the moving rod, and the output shaft of the third motor is connected to one end of the grinding wheel.
