the supporting shaft comprises a vertical shaft (10-3) penetrating through the mounting seat (7), a baffle plate (10-1) arranged at the bottom end of the vertical shaft (10-3) and two lug plates (10-2) symmetrically arranged at the top end of the vertical shaft (10-3), one end, close to the baffle plate (10-1), of the vertical shaft (10-3) is mounted on the mounting seat (7) through a bearing (9), a mounting groove is formed in the bottom of the mounting seat (7), and the baffle plate (10-1) and the bearing (9) are located in the mounting groove;
the dust cover (4-1) can prevent dust and sand blasting liquid from splashing and attaching to the threaded rod (3-1), ensures that the threaded rod (3-1) and the threaded sleeve (2-2) are in threaded connection and are clean, and avoids the phenomenon that the threaded rod (3-1) and the threaded sleeve (2-2) are inflexible in matching and are blocked;
during the sand blasting process, the sand blasting gun (13) can rotate 360 degrees;
the walking wheel mechanism comprises walking wheels (6) and an adjusting assembly which is arranged on the base (1) and used for adjusting the walking wheels (6) to move up and down along the vertical direction, the number of the walking wheels (6) is multiple, and the walking wheels (6) are arranged on the same circumference;
the walking brake mechanism comprises a sliding rod (23), a brake block (21) arranged below the sliding rod (23), a support seat arranged at the bottom of the base (1) and hinged with one end of the sliding rod (23), and a fixed plate (20) arranged at the bottom of the base (1) and used for the other end of the sliding rod (23) to penetrate through, wherein an inclined sliding groove (20-1) used for the other end of the sliding rod (23) to slide is formed in the fixed plate (20);
the supporting seat comprises a fixed sleeve (24) arranged at the bottom of the base (1) and a rotating seat (25) rotatably arranged in the fixed sleeve (24), one end of the sliding rod (23) is hinged with the rotating seat (25), and a rubber cushion block (22) is arranged on the bottom surface of the brake block (21);
when the sliding rod (23) slides from the highest position of the inclined sliding chute (20-1) to the lowest position of the inclined sliding chute (20-1), the brake block (21) vertically moves downwards along with the sliding of the sliding rod (23) until the bottom surface of the brake block (21) is tightly attached to the horizontal ground, so that the braking of the supporting device is realized; when the sliding rod (23) slides from the bottommost position of the inclined sliding chute (20-1) to the highest position of the inclined sliding chute (20-1), the brake block (21) moves upwards vertically along with the sliding of the sliding rod (23) and is separated from the horizontal ground, so that the braking of the supporting device is released.
2. The supporting device for the sand blasting and rust removing of the penstock as claimed in claim 1, wherein: the mounting seat (7) is fixedly mounted on the horizontal plate (3-2) through a first bolt (8).
3. The supporting device for the sand blasting and rust removing of the penstock as claimed in claim 1, wherein: the sand blasting gun support comprises a U-shaped frame (12-1) for installing a sand blasting gun (13) and a hinged plate (12-2) arranged at the bottom of the U-shaped frame (12-1), the hinged plate (12-2) is hinged with two ear plates (10-2) through a pin shaft (11), and the locking piece is a set screw (26).
4. The supporting device for the sand blasting and rust removing of the penstock as claimed in claim 1, wherein: one end of the arc-shaped pressing plate (16) is connected with the illuminating lamp support through a hinged shaft (19), the other end of the arc-shaped pressing plate (16) is fixedly installed on the illuminating lamp support through a second bolt (18), a groove matched with the illuminating lamp (14) is formed in the top surface of the illuminating lamp support, and an installation channel for installing the illuminating lamp (14) is formed between the groove and the arc-shaped pressing plate (16).
