Fine adjusting device for pipeline inner wall sand blower

Abstract

The invention discloses a fine adjusting device for a pipeline inner wall sand blower. The fine adjusting device comprises a supporting base, a transverse adjusting rod, a transverse limiting rod, a height adjusting column, a handle, a connecting cylinder, a sleeve, snap spring pieces, a clamping base and springs. The supporting base is formed by a base body and a rotating base. The height adjusting base is formed by a base and a connecting base. An inner thread and an outer thread are arranged on the connecting cylinder. The connecting base and the sleeve are both in threaded connection with the connecting cylinder. The springs are arranged on the outer side of the supporting base. The base and the sleeve are connected through a stop screw. The transverse adjusting rod is arranged on the side face of the base body and is in threaded connection with the base body. The transverse limiting rod is arranged on the side face of the base body and connected with the base body through a stop screw. According to the fine adjusting device for the pipeline inner wall sand blower, adjustment on the height and angle of a nozzle of the pipeline inner wall sand blower is achieved by arranging a transverse adjusting mechanism, a longitudinal adjusting mechanism and a limiting mechanism and adjusting the transverse position and the longitudinal position of the fine adjusting device, and the pipeline inner wall sand blowing effect can be better guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sand blasting, in particular to a fine-tuning device for a sand blaster on the inner wall of a pipeline. Background technique [0002] Pipeline inner wall sandblasting technology is a surface treatment technology commonly used in the surface treatment industry at present. The traditional pipeline inner wall sandblasting technology is to extend the existing pipeline inner wall sand blaster into the inner wall of the pipeline, and connect the sandblasting pipe and other devices to realize the pipeline Sandblasting on the inner wall, however, the position deviation of the nozzle on the inner wall of the pipeline is prone to occur during use in this way, resulting in unsatisfactory sandblasting effect on the inner wall of the pipeline. The support frame of the sand blaster on the inner wall of the pipeline is not easy to adjust, and the function of the support frame is to achieve support, and it is also diffi...

[0002] Pipeline inner wall sandblasting technology is a surface treatment technology commonly used in the surface treatment industry at present. The traditional pipeline inner wall sandblasting technology is to extend the existing pipeline inner wall sand blaster into the inner wall of the pipeline, and connect the sandblasting pipe and other devices to realize the pipeline Sandblasting on the inner wall, however, the position deviation of the nozzle on the inner wall of the pipeline is prone to occur during use in this way, resulting in unsatisfactory sandblasting effect on the inner wall of the pipeline. The support frame of the sand blaster on the inner wall of the pipeline is not easy to adjust, and the function of the support frame is to achieve support, and it is also difficult to fix it after adjustment. Therefore, a fine-tuning device is needed to realize the adjustment of the above-mentioned nozzles and solve the above-mentioned sandblasting effect. Suboptimal and Difficult to Adjust Issues
