Description

Technical Field

[0001] The utility model relates to the technical field of tray welding, and specifically relates to a welding device for processing cooling tower trays. Background Technique

[0002] The cooling tower tray is a key component in the cooling tower, also known as a packing tray or a water shower tray, and plays a crucial role in the cooling process of the cooling tower, directly affecting key performance indicators such as the cooling efficiency, water consumption, energy consumption, and operation stability of the cooling tower.

[0003] When the required size of the cooling tower tray is large, a single sheet cannot meet the requirements, and multiple sheets need to be spliced into the large-sized sheet required for the tray. After splicing, a welding device is required to weld and fix the multiple sheets.

[0004] After welding multiple sheets, in order to prevent the welding slag from adhering too tightly to the weld seam after cooling, resulting in cracks or stress concentration during cleaning, it is necessary to immediately clean the residue on the welding point. However, traditional welding devices often rely on welders to knock and clean the welding slag on the welding point. Since the welding area is in a high-temperature state, welders are prone to being scalded when cleaning the welding point. Therefore, those skilled in the art have provided a welding device for processing cooling tower trays to solve the problems raised in the above background technique. Content of the Utility Model

The robotic arm is located on one side of the workbench, and a welding torch is installed on the robotic arm. Side plates are installed on the front and rear sides of the workbench surface, and sliding grooves are horizontally opened on the side plates. A limiting rod is arranged on the lower side of the workbench surface, and a limiting cylinder is installed on the limiting rod. A through groove is opened on one side of the limiting cylinder, and a guiding rod is vertically installed at the center of the limiting cylinder. A striking column is sleeved in the limiting cylinder, a tooth groove is opened on the side of the striking column facing the through groove, a spring is installed at the bottom of the striking column, a special-shaped gear is arranged on the side of the limiting cylinder where the through groove is opened, a driving shaft is axially installed at the center of the special-shaped gear, and a motor is installed at one end of the driving shaft.

[0009] Preferably, the limiting rod is slidably clamped with the side plate through a chute. After the tower tray plate is welded, the limiting rod slidably clamped with the chute on the side plate is toggled to align the limiting cylinder on the limiting rod with the position of the weld seam.

[0010] Preferably, the motor is fixedly installed on the outer wall of the end of the limiting rod. The driving shaft penetrates through the end of the limiting rod and is drivingly connected to the motor. The driving shaft is rotatably sleeved on the two ends of the limiting rod.

[0011] Preferably, the special-shaped gear passes through the through groove and meshes with the tooth groove on the outer wall of the striking column. When the motor is started, the motor drives the driving shaft to rotate, and the driving shaft drives the special-shaped gear to rotate. During the rotation of the special-shaped gear, the outer wall with teeth drives the striking column to contract and compress downward after meshing with the tooth groove of the striking column.

[0012] Preferably, the central part of the striking column is slidably inserted into the guiding rod. The bottom end of the spring connected to the lower end of the striking column is in pressing contact with the bottom side wall of the limiting cylinder. When the tooth groove disengages from the special-shaped gear, the striking column quickly rebounds under the elastic potential energy of the spring, thus forming a striking effect, and knocking and conducting on the welded tower tray weld seam on the workbench through the tabletop, so as to achieve the effect of cleaning the weld seam.

When the motor 17 is started, the motor 17 drives the driving shaft 15 to rotate, and the driving shaft 15 drives the special-shaped gear 16 to rotate. During the rotation of the special-shaped gear 16, after the outer wall with teeth meshes with the tooth groove 13 of the striking column 12, it drives the striking column 12 to contract and compress downward. The central part of the striking column 12 is slidably inserted into the guiding rod 11.
