[0002] The inner wall of the existing concrete conveying cylinder needs to be subjected to a plasma arc surface quenching process after honing. In the existing quenching positioning structure, the nozzle is installed at the front end of the spray gun, and the upper end of the spray gun is fastened to the traveling guide rod. There are two points at the bottom of the spray gun Positioning bearing, during the quenching process, the positioning bearing is attached to the inner wall of the concrete delivery cylinder. Since the positioning bearing cannot automatically adjust its level during the quenching process, it is necessary to complete the level calibration before the quenching process. The entire calibration process It is time-consuming and labor-intensive, and it is easy to cause the horizontal calibration to be damaged during the movement of the traveling guide rod, which makes the quenching process uneven on the inner wall of the concrete delivery cylinder and affects the quality of the concrete delivery cylinder

The invention provides a quenching location structure of an internal wall of a concrete conveying cylinder. The quenching location structure ensures that the concrete conveying cylinder is not required to be subjected to manual horizontal calibration before a quenching technology, the time and labor are saved, the lower end faces of a front location bearing and a rear location bearing and the internal wall of the concrete conveying cylinder can be kept in horizontal states during the quenching technology, a distance between a nozzle and the internal wall of the concrete conveying cylinder is certain, a uniform quenching layer is guaranteed, and the quality of the concrete conveying cylinder is improved. The structure comprises a traveling guide rod, a spray gun and the nozzle, wherein the spray gun is arranged below the traveling guide rod, and the nozzle is mounted at the front end of the spray gun. The structure is characterized in that a convex connecting block is arranged at the lower end of the traveling guide rod, a mounting cavity of a connecting housing is sleeved with the spray gun, and two convex connecting plates are arranged at the upper part of the connecting housing.
