Problems solved by technology

[0006] 1. The paint remover will corrode the pipes and welded joints, cause damage to the pipes and reduce the performance
[0007] 2. The amount of paint remover and sandpaper is large and the cost is high
[0008] 3. The grinding effect on hard foreign matter such as welding spatter and scale is poor, and it takes a long time
[0009] 4. The efficiency of manual grinding is low, and personnel are prone to fatigue

Abstract

The invention discloses a small-diameter intensive tube bank weld junction grinding device and method. The device comprises a handpiece, a driving mechanism,grinding wheels, and driven wheels, whereinthe inside of the handpiece is containing space for containing a motor; the motor is connected with the driving mechanism to provide driving force for the driving mechanism; the grinding wheels are connected with one side of the driving mechanism which drives the grinding wheels to rotate through the driving mechanism; the driven wheels are connected with the other side of the driving mechanism;the motor axis is perpendicular to the grinding wheel axis; power output by the motor is made a vertical turn by matching the driving mechanism and the motor, and the power is output to the grinding wheels. The small-diameter intensive tube bank weld junction grinding device is compact in structure, with own radian, small in volume, light in weight, easy to carry, and especially suitable for the grinding of the small-diameter intensive tube bank in the construction site, so that the mechanical grinding of a narrow-gap weld junction is achieved.

Description

technical field [0001] The invention relates to the technical fields of mechanical manufacturing and non-destructive testing, in particular to a device and method for grinding small-diameter tube dense tube row welding joints. Background technique [0002] The heating surface of power plant boilers is mostly composed of tube rows composed of small-diameter tubes with a diameter of less than 100mm. In order to increase the heating surface area and improve the overall thermal efficiency of the unit, the pipeline arrangement is dense and the tube row structure on the heating surface is compact. Due to the structural characteristics of the power plant boiler, the distance between the pipes on the pipe row and the distance between the pipe rows are very small, which has caused great difficulties for installation, welding construction, and especially the follow-up weld quality inspection. [0003] For the detection of narrow-gap dense tube welding joints, advanced phased array det...
