Technical Field

[0001] The invention relates to the technical field of concrete pipe pile processing, in particular to a prestressed high-strength concrete pipe pile head manufacturing and processing machine. Background Art

[0002] Prestressed high-strength concrete pipe piles (PHC pipe piles) are an industrially prefabricated pile foundation material, primarily consisting of a cylindrical pile body, end plates, and steel ferrules. They are typically categorized into cross, conical, and open types. For example, during the production of conical PHC pipe piles, the pile head is often first formed and then welded to the end of the cylindrical pile body. During the processing of conical prestressed high-strength concrete pipe pile heads, it is usually necessary to grind the butt joint surfaces of the plates to reduce local stress concentration on the pile heads and make the forces on all sides of the pile heads more uniform during use. Usually, during the grinding process, workers first place the welded pile heads on a grinding table and manually use a grinding machine to perform circumferential grinding on the outer wall. However, this processing method has high labor intensity, long grinding time, and low processing efficiency. Summary of the Invention

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Embodiment: A prestressed high-strength concrete pipe pile head manufacturing and processing machine, such as Figure 1 - Figure 4 As shown, it includes a polishing box 1, in which a protruding processing table 11 is fixedly installed.

When the sliding door 12 is closed downward, the internal space of the polishing box 1 is closed, which can prevent the polishing debris from floating out.

[0022] The processing table 11 is driven to install a grinding table 2. The grinding table 2 is provided with a plurality of fixed cylinders 27 distributed in a circular array. The fixed cylinders 27 are used to fix the pile head 3. An electromagnet sheet is provided on the fixed cylinder 27. When the pile head 3 is placed inside the fixed cylinder 27, the electromagnet sheet firmly adsorbs the pile head 3 inside the fixed cylinder 27.

The grinding piece 4 includes a telescopic piece 44 fixedly mounted on the top of the grinding box 1. A mounting table 42 is fixedly connected below the telescopic piece 44. A drive box 43 is provided on the mounting table 42. A conical grinding cylinder 41 for grinding the pile heads 3 is driven and installed below the drive box 43.

[0023] In the present invention, a plurality of fixed cylinders 27 are respectively arranged in a circular distribution on the grinding table 2, and the grinding table 2 is driven and installed on the processing table 11. When the pile heads 3 need to be ground, the plurality of pile heads 3 are first placed inside the corresponding fixed cylinders 27, and then the grinding table 2 is driven to move on the processing table 11, so that the grinding table 2 moves to the inside of the grinding box 1, and then the telescopic part 44 drives the conical grinding cylinder 41 to move between the plurality of pile heads 3. At this time, the driving box 43 drives the conical grinding cylinder 41 to rotate, so that the outer wall of the conical grinding cylinder 41 contacts the welding surface of the plurality of pile heads 3 for grinding, thereby completing the grinding processing of the plurality of pile heads 3 quickly and efficiently.

[0024] It should be noted that a guide rail 111 is fixedly installed on the processing table 11, and a linear motor 26 is provided under the grinding table 2.

[0027] Among them, by rotating the connecting shaft 23 on the mounting plate 21, and coloring the gear set 215 below the connecting shaft 23, the connecting shaft 23 can drive multiple fixed cylinders 27 to rotate when rotating, so that the pile head 3 placed on the fixed cylinder 27 rotates during the grinding process, and the outer surface of the pile head 3 can be polished more evenly, so that the pile head 3 is subjected to more uniform force during use; in addition, since a first connecting gear 25 is provided at the upper end of the connecting shaft 23, and a second connecting gear 46 is provided below the driving shaft 45, when the driving shaft 45 moves downward, the second connecting gear 46 below the driving shaft 45 will mesh with the first connecting gear 25, so that the first connecting gear 25 and the second connecting gear 46 will transmit to each other, so that the driving shaft 45 drives the conical grinding cylinder 41 to rotate, and the pile head 3 placed on the fixed cylinder 27 can also be rotated by the cooperation of the first connecting gear 25 and the second connecting gear 46.
