Description

Technical Field

[0002] Reinforced concrete prestressed pipe piles, also known as concrete precast piles, are prefabricated in a prefabricated component processing plant, and after being cured and reaching the designed strength, they are transported to the construction site. Prestressed concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. Pre-tensioned prestressed pipe piles are a kind of hollow cylindrical slender concrete prefabricated components made by pre-tensioning prestressing technology and centrifugal forming method. They are mainly composed of a cylindrical pile body, end plate and steel sleeve. Reinforced concrete precast piles have the advantages of simple production, high strength, high rigidity and can be made into various cross-sectional shapes. They are a widely used pile type.

[0003] The pipe pile processing device under the existing technology can basically meet the processing requirements of pipelines.

A plurality of fixed arc plates are slidably connected to the bottom of the lower centrifugal semi-cylinder, and a plurality of grooves are provided on one side of the fixed arc plate close to the inner wall of the lower centrifugal semi-cylinder.

[0010] Furthermore, the fixing mechanism also includes a plurality of fixing blocks fixedly connected to the side wall of the lower centrifugal semi-cylinder, a sliding groove 1 is provided on the fixing block, a sliding block is slidably connected inside the sliding groove 1, a fixing screw hole is provided in the middle of the sliding block, and the fixing screw hole corresponds to the locking nut.

A centrifugal spring is provided inside the sliding grooves 2. The centrifugal spring is fixedly connected to one end of the scraper strip.

[0013] The processing method of the prestressed concrete pipe pile processing device comprises the following steps: S1: First, put the skeleton of the pipe pile into the lower centrifugal semi-cylinder, then sprinkle the prefabricated concrete into the lower centrifugal semi-cylinder evenly according to the proportion through the pipeline, then put the upper centrifugal semi-cylinder directly above the lower centrifugal semi-cylinder, manually rotate the auxiliary tightening nut, and rotate the auxiliary tightening nut into the auxiliary screw hole, so as to facilitate the upper centrifugal semi-cylinder and the lower centrifugal semi-cylinder to fit tightly; S2: The upward pulling force of the fixed arc piece is increased by the connecting plate in the fixing mechanism, and the extrusion force of the fixed arc piece on the fixed ring inside the lower centrifugal semi-cylinder is increased. This arrangement is conducive to increasing the friction between the fixed arc piece and the surface of the fixed ring, thereby further fixing the fixed ring inside the lower centrifugal semi-cylinder; S3: Scrape the inner wall of the pipe pile. The output shaft rotates to drive the rotating disk to rotate. At this time, the scraper strip inside the rotating disk slides outward along the second sliding groove under the action of centrifugal force. This setting can stir the concrete inside the lower centrifugal semi-cylinder on the one hand, so that the concrete adhering to the skeleton is evenly distributed. On the other hand, the rotating scraper strip is close to the inner wall of the fixed ring. The rotation of the scraper strip can control the thickness of the concrete adhering to the side wall of the skeleton, thereby ensuring the quality of the pipe pile. This setting is also beneficial to improving the smoothness of the inner wall of the pipe pile.

[0014] The present invention has the following beneficial effects: (1) In the present invention, the locking nut is manually rotated, and the locking nut is screwed down to the inside of the fixed screw hole below the auxiliary screw hole. At this time, the locking nut rotates inside the fixed screw hole. Under the rotation of the locking nut, the sliding block slides upward along the sliding groove on the fixed block. At this time, the sliding block drives the bottom telescopic rod to stretch upward. When the telescopic rod is stretched upward, the tension spring is stretched by the sliding block and becomes longer. When the length of the tension spring becomes longer, the tension of the tension spring on the bottom connecting plate of the telescopic rod becomes greater. At this time, the upward pulling force of the connecting plate on the fixed arc piece increases, and the extrusion pressure of the fixed arc piece on the fixed ring inside the lower centrifugal semi-cylinder increases. This arrangement is conducive to increasing the friction between the fixed arc piece and the surface of the fixed ring, thereby further fixing the fixed ring inside the lower centrifugal semi-cylinder, so that the skeleton on the fixed ring will not shake, thereby improving the quality of the produced pipe piles; (2) The present invention, by setting a centrifugal mechanism, when the frame and the fixed ring are installed and fixed, the drive motor is started, the drive motor rotates to drive the output shaft to rotate, the output shaft rotates to drive the transmission belt to rotate, the transmission belt rotates to drive the rotating shaft to rotate, the rotating shaft rotates to drive the gear to rotate, the gear rotates to drive the gear ring to rotate, the gear ring rotates to drive the combination of the lower centrifugal semi-cylinder and the upper centrifugal semi-cylinder to rotate, at this time, the rotation of the lower centrifugal semi-cylinder drives the auxiliary roller just above the fixed base to rotate closely against the limit groove on the outer wall of the lower centrifugal semi-cylinder, such a setting is conducive to improving the stability of the rotation of the lower centrifugal semi-cylinder; (3) In the present invention, the rotation of the output shaft drives the transmission belt to rotate, the rotation of the transmission belt drives the rotation of the rotating shaft, the rotation of the rotating shaft drives the gear to rotate, the rotation of the gear drives the gear ring to rotate, and the rotation of the gear ring drives the combination of the lower centrifugal semi-cylinder and the upper centrifugal semi-cylinder to rotate. When the driving motor rotates at high speed, the concrete inside the lower centrifugal semi-cylinder adheres to the skeleton under the action of centrifugal force, and the rotation of the output shaft drives the scraper strips on the rotating disk to rotate. This arrangement is conducive to making the rotation direction of the lower centrifugal semi-cylinder opposite to the rotation direction of the output shaft inside the lower centrifugal semi-cylinder, thereby increasing the relative rotation speed of the concrete inside the lower centrifugal semi-cylinder and increasing the centrifugal force of the concrete inside the lower centrifugal semi-cylinder, so that the concrete inside the lower centrifugal semi-cylinder quickly adheres to the side wall of the skeleton, accelerating the forming of the pipe pile and improving the production efficiency of the device; (4) The present invention provides a scraping mechanism. When the output end of the driving motor in the device rotates at a high speed, the output shaft rotates to drive the rotating disk to rotate. At this time, the scraper strip inside the rotating disk slides outward along the second sliding groove under the action of centrifugal force. This arrangement can, on the one hand, stir the concrete inside the lower centrifugal semi-cylinder so that the concrete adhering to the skeleton is evenly distributed. On the other hand, the rotating scraper strip is closely attached to the inner wall of the fixed ring. The rotation of the scraper strip can control the thickness of the concrete adhering to the side wall of the skeleton, thereby ensuring the quality of the pipe pile. This arrangement is also conducive to improving the smoothness of the inner wall of the pipe pile.

At this time, the prefabricated concrete is evenly sprinkled into the lower centrifugal semi-cylinder 15 through the pipeline according to the proportion. At this time, the upper centrifugal semi-cylinder 201 is placed directly above the lower centrifugal semi-cylinder 15, and the auxiliary tightening nut 202 is manually rotated to rotate the auxiliary tightening nut 202 to the inside of the auxiliary screw hole 204, which is conducive to the upper centrifugal semi-cylinder 201 and the lower centrifugal semi-cylinder 15 tightly fitting; S2: The upward pulling force of the fixed arc piece 402 is increased by the connecting plate 409 in the fixing mechanism 4, and the extrusion force of the fixed arc piece 402 on the fixed ring 17 inside the lower centrifugal semi-cylinder 15 is increased.

A prestressed concrete pipe pile processing device according to claim 6, characterized in that: A scraping mechanism (5) is provided at one end of the output shaft (14) away from the drive motor (13), and the scraping mechanism (5) comprises a plurality of rotating disks (501) fixedly connected to one end of the output shaft (14) away from the drive motor (13), the rotating disks (501) being provided with a plurality of sliding grooves (502), a scraper strip (503) being slidably connected inside the sliding grooves (502), a centrifugal spring (504) being provided inside the sliding grooves (502), and the centrifugal spring (504) being fixedly connected to one end of the scraper strip (503).

8. A method for processing a prestressed concrete pipe pile using a processing device for processing a prestressed concrete pipe pile according to claim 7, characterized in that: It includes the following steps: S1: First, the skeleton (16) for making the pipe pile is placed inside the lower centrifugal semi-cylinder (15), and then the prefabricated concrete is evenly sprinkled into the lower centrifugal semi-cylinder (15) through the pipeline according to the proportion. At this time, the upper centrifugal semi-cylinder 201 is placed directly above the lower centrifugal semi-cylinder 15, and the auxiliary tightening nut 202 is manually rotated to rotate the auxiliary tightening nut 202 into the auxiliary screw hole 204, so that the upper centrifugal semi-cylinder 201 is closely fitted with the lower centrifugal semi-cylinder 15; S2: The upward pulling force on the fixed arc piece (402) is increased by the connecting plate (409) in the fixing mechanism (4), and the squeezing force of the fixed arc piece (402) on the internal fixing ring (17) of the lower centrifugal semi-cylinder (15) is increased. This arrangement is conducive to increasing the friction between the fixed arc piece (402) and the surface of the fixing ring (17), thereby further fixing the fixing ring (17) inside the lower centrifugal semi-cylinder 15; S3: Scrape the inner wall of the pile. The output shaft (14) rotates to drive the rotating disk (501) to rotate. At this time, the scraper strip (503) inside the rotating disk (501) slides outward along the second sliding groove (502) under the action of centrifugal force. This arrangement can, on the one hand, stir the concrete inside the lower centrifugal semi-cylinder (15) so that the concrete adhering to the frame (16) is evenly distributed. On the other hand, the rotating scraper strip (503) is closely attached to the inner wall of the fixed ring (17). The rotation of the scraper strip (503) can control the thickness of the concrete adhering to the side wall of the frame (16), thereby ensuring the quality of the pile. This arrangement is also conducive to improving the smoothness of the inner wall of the pile.
