Description

Technical Field

[0001] This utility model relates to a welding rod insulation bucket, and more particularly to an insulation bucket used for controlling the insulation temperature at 80-110℃ when installing high-pressure weld joints on special equipment. Background Technology

[0002] Special equipment in thermal power plant boilers operates at pressures above 20 MPa and temperatures above 500℃. During welding and installation, the internal quality requirements of the weld joints are very high, necessitating strict adherence to regulations and standards throughout the welding process. Moisture-damaged welding electrodes are prone to cracking and porosity, affecting weld quality and leading to substandard welds. In severe cases, rework may be necessary, impacting the construction schedule. Therefore, the "Welding Technical Specification for Thermal Power Plants" (DL / T) is essential. Regulations 869 stipulate that welding rods used for welding critical components should be stored in a dedicated insulated container with a temperature range of 80-110℃ and taken out as needed. Existing insulated containers use a secondary welding line as their power source, with an open-circuit voltage of 60-90V and a welding voltage of 20-30V, resulting in unstable voltage and unstable container temperatures. Actual measurements of six insulated containers on-site, based on a 10-hour workday, revealed that the temperature was maintained within the specified range for an average of only 1.5 hours, with the remaining 8.5 hours below 80℃. The container cannot guarantee a sustained welding rod temperature within the 80-110℃ range. Therefore, a welding rod insulated container with stable insulation is urgently needed. Furthermore, welders wear welding gloves when handling welding rods, and at least 4-5 rods are handled at a time. The exposed rods are susceptible to moisture absorption during the waiting period, affecting welding quality. Frequent opening of the container lid during handling also causes a drop in the overall insulation temperature. Summary of the Invention

[0003] This invention provides a welding electrode insulation bucket that enables limited ejection of welding electrodes, solving the technical problems of existing insulation buckets that require frequent opening of the lid to retrieve welding electrodes and have poor insulation effect.

[0004] This utility model solves the above technical problems through the following technical solution: A welding rod insulation bucket with limited electrode ejection capability includes a bucket base, a cylindrical bucket body fixedly mounted on the bucket base, welding rods placed inside the cylindrical bucket body, a lid hinge seat located on one side of the top opening of the cylindrical bucket body, a lid hinged to the lid hinge seat, and a lid latch located on the other side of the top opening of the cylindrical bucket body. The top surface of the bucket base has an inclined lower surface of the inner cavity, on which the welding rod is vertically positioned. A spring chamber is located at the left end of the bucket base, with a button cylindrical through-hole and a semi-circular through-hole communicating with the inner cavity of the insulation bucket on the top surface of the spring chamber. A spring chamber is located on the bottom surface of the inner cavity. There is a spring, and a lifting elastic plate is connected to the top of the spring. A button cylinder is connected to the top surface of the lifting elastic plate. The top of the button cylinder passes through the button cylinder and exits through the through hole and is located on the left side of the cylindrical barrel body. A pre-emerged welding rod is set in the semi-circular through hole. The lower end of the pre-emerged welding rod is set on the top surface of the lifting elastic plate below the semi-circular through hole. A rotatable inner cover plate is movably set inside the barrel lid. An inner cover plate welding rod ejection through hole is set on the rotatable inner cover plate. A barrel lid welding rod ejection through hole is set on the barrel lid. The inner cover plate welding rod ejection through hole and the barrel lid welding rod ejection through hole are set correspondingly. The upper end of the pre-emerged welding rod is set below the inner cover plate welding rod ejection through hole.

[0005] An inner lid knob is located in the center of the lid, and the inner lid knob is connected to a rotatable inner lid plate; a handle is located in the middle of the cylindrical barrel.

[0006] An inner liner is installed inside a cylindrical barrel. Between the inner liner and the outer shell of the cylindrical barrel, there are layers of asbestos and aluminum silicate needled blankets, respectively. A heating resistance wire is installed between the asbestos layer and the aluminum silicate needled blanket layer. A lead wire is connected to the heating resistance wire. A temperature controller is connected to the other end of the lead wire. The temperature controller is connected to a 220-volt power supply via a connecting cable and a plug.

[0007] This invention allows for the limited ejection of welding rods from inside the barrel through the welding rod ejection hole in the barrel lid by pressing a button cylinder without opening the lid, thus ensuring a constant temperature inside the barrel and guaranteeing that the welding rods used during welding meet the required temperature. At the same time, stable mains power supply and a temperature controller ensure stable temperature inside the barrel. Attached Figure Description
