Description

Technical Field

[0001] The utility model relates to a pipe pile centrifuge. Background Art

[0002] In the late 1960s, the Ministry of Railways' Fengtai Bridge Factory began producing pre-tensioned concrete pipe piles (PC pipe piles), primarily for railway and bridge infrastructure. In the 1970s, post-tensioned prestressed concrete pipe piles were developed and produced. Currently, domestic demand is surging, and pipe pile centrifuges are used in pipe pile production.

[0003] The pipe pile centrifuge consists of an upper drum and a lower drum, with a steel frame and concrete between the upper and lower drum covers. Pipe piles for construction can be obtained through centrifugal action. Currently, the connection between the upper and lower drums is achieved by bolts. Due to the certain length of the pipe piles, the number of bolts on one side is large. The production site generally completes the tightening of the bolts individually by manual labor, which is inefficient and makes the labor intensity of the operators high during the pipe pile production process. Utility Model Content

[0004] In view of the shortcomings existing in the above problems, the utility model provides a pipe pile centrifuge.

[0005] To achieve the above-mentioned purpose, the utility model provides a pipe pile centrifuge, comprising an upper cylinder with an upper cylinder convex edge and a lower cylinder with a lower cylinder convex edge, an upper groove and an upper protrusion are processed on the inner ring of the upper cylinder, and a lower groove and a lower protrusion are processed on the inner ring of the lower cylinder, the upper groove matches the lower protrusion, and the upper protrusion matches the lower groove, and the upper cylinder and the lower cylinder form a sealed cylinder structure; locking mechanisms are evenly distributed on the upper cylinder convex edge and the lower cylinder convex edge; the locking mechanism enters the vertical shaft buckle through the locking inclined surface to achieve locking.

[0006] As a further improvement of the present invention, the locking mechanism includes a flange block fixed to the convex edge of the lower cylinder, a stepped inner hole is processed in the flange block, a locking shaft is installed at the inner hole, a cover is installed on the outside of the inner hole by bolts, and a locking port is processed on one side of the cover.

[0007] As a further improvement of the present invention, the locking mechanism includes a vertical shaft, which is fixed to the upper cylinder convex edge by bolts, and the vertical shaft passes through the upper cylinder convex edge. The lower part of the vertical shaft is processed with a vertical shaft buckle, and the vertical shaft buckle is in the shape of an inverted right triangle.

[0008] As a further improvement of the present invention, the locking shaft includes a locking bevel close to the vertical shaft side, the locking bevel matches the vertical shaft buckle, the middle part of the locking shaft is processed with a spring seat, the locking shaft is processed with a handle away from the vertical shaft end, a locking protrusion is processed between the handle and the spring seat, and the locking protrusion matches the locking mouth.

[0009] As a further improvement of the present invention, a spring is installed at the spring seat.

[0010] The beneficial effects of the utility model are:

[0011] By matching the upper groove with the lower protrusion and vice versa, the sealing performance of the pile centrifuge is greatly improved during rotation. At the same time, a locking mechanism is used instead of bolt connection, which greatly reduces the labor intensity of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-7As shown, a pipe pile centrifuge described in an embodiment of the present invention includes an upper cylinder 1 with an upper cylinder convex edge 11 and a lower cylinder 2 with a lower cylinder convex edge 21, an upper groove 12 and an upper protrusion 13 are processed at the inner ring of the upper cylinder 1, and a lower groove 23 and a lower protrusion 22 are processed at the inner ring of the lower cylinder 2, the upper groove 12 matches the lower protrusion 22, the upper protrusion 13 matches the lower groove 23, and the upper cylinder 1 and the lower cylinder 2 form a sealed cylinder structure; locking mechanisms 3 are evenly distributed at the upper cylinder convex edge 11 and the lower cylinder convex edge 21; the locking mechanism 3 enters the vertical shaft buckle 311 through the locking inclined surface 341 to achieve locking. The locking mechanism includes a flange block 32 fixed to the lower barrel flange 21. A stepped inner hole 321 is machined into the flange block 32, into which a locking shaft 34 is mounted. A cover 33 is bolted to the outer side of the inner hole 321, and a locking opening 331 is machined on one side of the cover 33. The locking mechanism includes a vertical shaft 31, which is fixed to the upper barrel flange 11 via bolts. The vertical shaft 31 passes through the upper barrel flange 11, and a vertical shaft buckle 311 is machined at the bottom of the vertical shaft 31. The vertical shaft buckle 311 is in the shape of an inverted right triangle. The locking shaft 34 includes a locking bevel 341 near the vertical shaft 31. The locking bevel 341 mates with the vertical shaft buckle 311. A spring seat 342 is formed in the middle of the locking shaft 34. A handle 344 is formed on the end of the locking shaft 34 away from the vertical shaft 31. A locking protrusion 343 is formed between the handle 344 and the spring seat 342. The locking protrusion 343 mates with the locking opening 311. A spring 35 is installed on the spring seat 342.

[0021] By matching the upper groove with the lower protrusion and vice versa, the sealing performance of the pile centrifuge is greatly improved during rotation. At the same time, a locking mechanism is used instead of bolt connection, which greatly reduces the labor intensity of the operator.

[0022] In order to facilitate understanding of the present invention, the following description will be given in conjunction with the accompanying drawings.

[0023] Place the steel ball cage and concrete into the lower cylinder, manually pull the handle outward and turn it 90 degrees (see Figure 5 ), the locking shaft moves outward against the spring force, while the locking protrusion rests against the outer side of the cover, and the locking bevel moves away from the vertical shaft. The upper cylinder descends until the upper groove mates with the lower protrusion, and vice versa, forming a sealed space. When the centrifuge is rotated clockwise by an external force, the joints between the upper groove and the lower protrusion, and the joints between the upper protrusion and the lower groove, oppose the direction of rotation, preventing concrete from leaking through the gaps between the joints. Simultaneously, the vertical shaft descends, and the handle is manually reset. The locking bevel, under the action of the spring force, enters the vertical shaft buckle, locking the joint and allowing entry to the lower working section.

[0024] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
