Description

Technical Field

[0001] The utility model relates to the technical field of flame spray guns, in particular to an arc type flame spray gun. Background Art

[0002] The use of power lines brings great convenience to our daily use of electricity. Power lines are generally erected in the air. Kites, cloth strips, plastic sheets, hornet's nests and other light objects have always been a hidden danger to the safe operation of power lines. Once entangled in the power lines, the lines will cause leakage, arcing, short circuit and other faults, resulting in large-scale power outages. The existing method of removing high-altitude floating objects generally uses arc flamethrowers to burn them. At higher locations that cannot be reached by humans, drones equipped with arc flamethrowers are usually used to clean floating objects. In low locations like cities, insulating pull rods are usually used to fix the arc flamethrowers, and floating objects are cleared by manual hand-held means.

[0003] Most existing arc flame spray guns are fixed by threading them onto an insulating rod so that they are fixed together to form a whole. However, the internal structure of the arc flame spray gun is complex and the outer surface is irregular, which makes it easy to bump into other objects during use. Over time, the threads at the connection will become loose, which will cause the arc flame spray gun to fall. At the same time, it is inconvenient to install and disassemble the arc flame spray gun. It is necessary to design an arc flame spray gun to solve the above-mentioned problems. Utility Model Content

[0010] Furthermore, a fixing bolt is provided at the rear bottom of the movable seat, and the middle position of the fixing bolt is close to the rear side of the handle column;

[0011] Through the above technical solution, after the extension column is fixed, a fixing bolt is installed at the rear bottom of the movable seat to limit the position of the lower pressure wheel and the handle column, preventing the lower pressure wheel from rotating, thereby preventing the lower pressure wheel from loosening and causing the extension column clamping effect to disappear.

[0012] Furthermore, a positioning column is provided at the bottom of the arc flame spray gun, the outer side of the positioning column is engaged with the inner upper end of the fixed tube, and a hose connector is provided at the bottom of the positioning column;

At the same time, the hose connector facilitates the installation of the fuel hose.

[0014] Furthermore, the inner bottom of the fixing pipe is threadedly connected to the outer side of the upper end of the connecting screw sleeve;

[0015] The above technical solution facilitates fixed connection between the fixing tube and the insulating pull rod, and is also convenient for installation and disassembly.

[0016] Furthermore, the flame spraying end of the arc flame spray gun is threadedly connected to the rear end of the fixed sleeve, and the front end of the fixed sleeve is threadedly connected to the flame spraying tube;

[0017] By adopting the above technical solution, a flame spraying tube is installed in a narrow position where the arc flame spraying gun is not easy to be inserted, thereby extending the flame spraying position of the arc flame spraying gun and improving work efficiency.

[0018] Furthermore, the fixed tube, the arc flame spray gun, the fixed seat and the movable seat are all made of insulating materials, and the surfaces are provided with an insulating coating;

[0019] The above technical solution improves the safety performance of fire-spraying treatment of debris in power lines.

[0020] The utility model has the following beneficial effects:

[0021] In the utility model, first, the fixed tube is installed on the insulating pull rod through the connecting screw sleeve, and the hose is passed through the insulating pull rod and the fixed tube, and fixed to the bottom of the arc flame spray gun through the hose connector. Then, the arc flame spray gun is installed on the upper end of the fixed tube through the positioning column for support, so that the outer side of the positioning column is engaged with the outer upper end of the fixed tube. When the arc flame spray gun is installed, the extension column arranged on the rear side thereof is fitted with the rear side of the fixed seat. Secondly, the movable seat is installed on the rear side of the fixed seat, and the lower pressure wheel is rotated eccentrically on the fixed column by the handle column. The protruding position presses the extension column and the fixed seat tightly. At the same time, due to the rotation of the protruding position of the lower pressure wheel, the movable seat moves rearward, and the left and right ends of the front side of the movable seat are in a pulling state with the connecting groove. Finally, the fixing bolt is installed on the movable seat to prevent the rotation of the lower pressure wheel, so as to prevent the relaxation of the lower pressure wheel from causing the clamping effect of the extension column to disappear, thereby facilitating the installation and disassembly of the arc flame spray gun and clamping the arc flame spray gun and the fixed tube during installation to increase the connection performance between the arc flame spray gun and the fixed tube, thereby avoiding the risk of the arc flame spray gun falling.
