Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation construction equipment and relates to a rolling rack for processing the outer wall of a cylindrical piece. Background Art

[0002] Pile foundation construction equipment includes numerous cylindrical components, such as rotary drill barrels, drill rods, and guide tubes. The production, repair, and maintenance of these components all require a rolling stand. This allows workers to rotate the cylindrical components and adjust their position during tasks like grinding and welding. However, due to the significant variations in length of components like rotary drill barrels, drill rods, and guide tubes, existing rolling stands struggle to uniformly support these components, necessitating structural optimization and improvement.

[0008] The utility model has the advantages:

[0009] 1. The span of this rolling frame can be adjusted at any time, so that it can adapt to cylindrical parts of different lengths, so that it can support rotary drilling tubes, drill rods, guide tubes, etc.

[0010] 2. In this rolling frame, the distance between each pair of support wheels is adjustable, so that it can adapt to cylindrical parts with different outer diameters, thereby achieving stable support for cylindrical parts with different outer diameters.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 、 Figure 2 and Figure 3 As shown, a rolling frame for machining the outer wall of a cylindrical component comprises a fixed frame 1, a guide rail 2, and a sliding frame 3, which is slidably connected to the guide rail 2. A pair of mounting frames 4 are symmetrically fixed to the tops of the fixed frame 1 and the sliding frame 3. Each mounting frame 4 is rotatably connected to a support wheel 5. The axis of each support wheel 5 is parallel to the axis of the cylindrical component, and the axis of the guide rail 2 is also parallel to the axis of each support wheel 5. In this rolling frame, the sliding frame 3 can slide on the guide rail 2, allowing the distance between the two pairs of support wheels 5, and thus the span of the rolling frame, to be adjusted at any time to accommodate cylindrical components of different lengths, so that it can support rotary drilling barrels, drill rods, pipes, etc.

[0018] like Figure 1 and Figure 2 As shown, the two opposing surfaces of each pair of mounting brackets 4 are inclined surfaces, each of which is provided with a plurality of mounting grooves 41 spaced evenly apart, into which each support wheel 5 can be mounted. By selecting different mounting grooves 41, the mounting position of the support wheel 5 can be changed, thereby adjusting the distance between the two support wheels 5 on each pair of mounting brackets 4 to accommodate cylindrical parts of different outer diameters, thereby achieving stable support for cylindrical parts of different outer diameters.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the bottom end of the sliding frame 3, near the fixed frame 1, is equipped with a pair of guide wheels 6. The bottom end of the sliding frame 3, away from the fixed frame 1, is equipped with a pair of supporting legs 7. The bottom of the supporting legs 7 and the outer circumference of the guide wheels 6 both fit into the top of the guide rail 2. A pull rod 8 is installed within the sliding frame 3, which can be pulled along the axis of the sliding rail and extended toward the supporting legs 7. To move the sliding frame 3, the pull rod 8 is pulled out and lifted upward, thereby lifting the two supporting legs 7 off the top of the guide rail 2, allowing the sliding frame 3 to be easily moved with the support of the guide wheels 6. Once the sliding frame 3 has moved to the desired position, the pull rod 8 is lowered, returning the two supporting legs 7 to the guide rail 2, thus securing the sliding frame 3. Furthermore, the lever action makes it easy to lift the supporting legs 7 using the pull rod 8. This makes the span of the rolling frame not only adjustable, but also very convenient.

[0020] like Figure 1 and Figure 2 As shown, the tops of the fixed frame 1 and the sliding frame 3 are both ridge-shaped. Since both grinding and welding will generate a large amount of debris, the ridge-shaped tops of the fixed frame 1 and the sliding frame 3 can make the debris slide down freely or be more convenient to clean.

[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
