Description
Technical field
The utility model relates to steel pipe manufacture field, specifically the ramming head displacement mechanism of shot-blast apparatus in a kind of steel pipe.
Background technology
The inside and outside wall of large-scale steel pipe, before anticorrosion with painting coating, first must carry out sandblasting Shot Blasting, to remove Surface Rust.First carry out sandblasting ball blast with outer shot-blast apparatus to the outer wall of steel pipe, more manually to eliminate rust to inwall, after namely workman puts on protective garment, puts on goggles, hand-held blast tube enters in steel pipe, utilizes high-pressure sand blast to be impacted by rusty scale.There is many defects in artificial rust cleaning: artificial sandblasting is uneven, and derusting is unstable, inefficiency; Security is low, and clothing is easy to wear; And when steel pipe caliber hour, people cannot pierce, operation is required great effort more.
Utility model content
Technical problem to be solved in the utility model is the defect overcoming the existence of above-mentioned prior art, the ramming head displacement mechanism of shot-blast apparatus in a kind of steel pipe is provided, ramming head can be sent into steel pipe, and move around in steel pipe, to realize evenly, sandblasting ball blast fast, substitute artificial sandblasting, not only increase derusting, and improve the security of interior ball blast, can also extend in the little steel pipe of caliber, versatility is good.
For this reason, the technical solution adopted in the utility model is as follows: the ramming head displacement mechanism of shot-blast apparatus in steel pipe, its technical characteristic is, it comprises guide rail, dolly, ramming head arm and ramming head, and dolly is provided with ramming head arm lifting assembly, and ramming head is installed in the front end of ramming head arm, rear end is arranged on ramming head arm lifting assembly, and the displacement of vertical direction is realized by ramming head arm lifting assembly, the bottom of dolly is provided with the roller coordinated with guide rail, and roller drives dolly to move horizontally on guide rail under the driving of Power Component.
Ramming head can be sent in steel pipe by ramming head displacement mechanism, is realized the displacement of vertical direction by ramming head arm lifting assembly, to adapt to the steel pipe of different specification size; Realized the displacement of horizontal direction by the movement of dolly on guide rail, ramming head is moved around in steel pipe, complete the sandblasting ball blast of steel pipe inner wall.The at the uniform velocity movement of dolly makes ramming head more even to steel pipe inner wall sandblasting ball blast everywhere, eliminates rust effective; Instead of artificial sandblasting, improve ball blast efficiency, also improve security.It is that in the steel pipe of 4 ~ 22 meters, versatility is high that ramming head and ramming head arm can extend into internal diameter, avoids because the little workman of caliber cannot climb to the problem that can not complete interior ball blast in pipe.
As improvement, described ramming head arm lifting assembly comprises left and right two groups of symmetrically arranged cranes and horizontal bearing, on the bearing of ramming head arm between two groups of cranes, described crane comprises forward and backward two columns, two columns form a vertical slide rail, and the end of bearing is provided with bearing block, and described bearing block is embedded between two columns, and can slide up and down along vertical slide rail, realize the displacement in the vertical direction of ramming head arm; The top of forward and backward two columns is provided with a cover plate, and bearing block is provided with screw mandrel, and the top of screw mandrel to be run through after cover plate by nut check from bottom to top, realizes ramming head arm location in the vertical direction.This setting, makes the structure of ramming head arm lifting assembly simple, firm to the support of ramming head arm, and lifting steadily, reliably; Simple, firm to ramming head arm positioning action in vertical direction.
As improvement, described ramming head displacement mechanism also comprises a travelling carriage near ramming head arm front end, this travelling carriage is also provided with an above-mentioned ramming head arm lifting assembly; Ramming head arm lifting assembly on travelling carriage and the ramming head arm lifting assembly on dolly complete the displacement in the vertical direction of ramming head arm and location jointly.This setting, is supported and lift adjustment by the front end of ramming head arm lifting assembly to ramming head arm on travelling carriage, and the ramming head arm making length longer can not be sagging because the ramming head quality of front end is heavy, ensure that ramming head arm horizontal positioned, operate steadily.
As improvement, the outside of described column is provided with up-small and down-big triangular reinforced plate.This setting, makes the setting of column more firm, and the load bearing effect of ramming head arm lifting assembly is better.
As improvement, described dolly is provided with the hydraulic means for driving ramming head to rotate, and ramming head arm is provided with the driving belt for sending sand to ramming head.This setting, makes ramming head sandblasting ball blast better effects if.
As improvement, described guide rail is also provided with for stoping dolly to continue the scotch moved forward.This setting, makes scotch can brake dolly rapidly, avoids dolly still to move forward by inertia after its Power Component is closed, ensure that the advanced positions of ramming head is more accurate.
