Detailed Description

Referring to fig. 1-2, the device for removing the inner wall of the building steel pipe comprises a frame 10, a group of wheels 11 fixed on the lower part of the frame 10, a cylinder end fixedly supported by a hydraulic cylinder 12 on the lower part of the frame 10, a piston end hinged support leg 13 supporting the hydraulic cylinder 12, at least two groups of clamping jaws 14 fixed on the front end of the upper part of the frame 10, wherein the clamping jaws 14 can fix the building steel pipe 90 on the frame 10, and a front support 15 fixed on the rear part of the building steel pipe 90.

The middle part of the frame 10 is provided with a hollow-out part 40, two rails 41 are arranged in the hollow-out part 40, the axial direction of the rails 41 is parallel to the axis of the building steel pipe 90, sliding plates 42 are sleeved outside the two rails 41, and the sliding plates 42 can slide along the rails 41.

The sliding plate 42 is fixed with the motor 20, the output shaft of the motor 20 is coaxially connected with one end of the rotating rod 21, the rotating rod 21 passes through the front support 15, and the other end of the rotating rod 21 is fixed with the cleaning head 22.

The rear end of the frame 10 is fixed with the cylinder body of the thrust hydraulic cylinder 50, and the piston end of the thrust hydraulic cylinder 50 is fixedly connected with the sliding plate 42, which provides thrust for the movement of the sliding plate.

Referring to fig. 3-4, the cleaning head 22 comprises a rear friction section 23 and a front cleaning section 24, wherein a plurality of bristles 25 are radially distributed on the cleaning section 24, and the outer diameter of the friction section 23 is matched with the inner diameter of the building steel pipe 90.

In order to wash away the friction debris, a water pipe bracket 30 is fixed on the frame 10 obliquely behind the building steel pipe 90, a water pipe 31 is arranged on the water pipe bracket 30, the outlet of the water pipe 31 is aligned with the rear end of the building steel pipe 90, and a plurality of water through holes 26 are arranged in the axial direction of the friction section 23.

For uniform cooling, a plurality of water passage holes 26 are uniformly distributed on the same circumference, see fig. 4.

The working principle is as follows:

when in use, the construction steel pipe 90 is fixed to the frame 10, see fig. 1.

Referring to fig. 5, extending the piston end of the support cylinder 12 raises the rear (right side in the drawing) of the frame 10, which enables forward flow of debris and reduces obstruction to the cleaning operation.

At this time, the motor 20 is turned on to drive the cleaning head 22 to rotate, and at the same time, the piston end of the thrust hydraulic cylinder 50 is extended to push the sliding plate 42 to move forward, so that the cleaning head 22 enters the building steel pipe 90, and the cleaning head 22 starts to clean the inner wall thereof.

The cleaning operation is gradually completed as the slide plate 42 is continuously pushed.

If the temperature needs to be reduced and the building steel pipe is cleaned, the water pipe 31 is opened, cleaning water enters from the rear of the building steel pipe 90, the temperature of the friction section 23 is reduced when the cleaning water passes through the water through hole 26, and after the cleaning water flows out of the water through hole 26, the friction fragments are taken away, so that the cleaning operation is convenient.

See the prior art for additional details.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
