Description

Technical Field

[0001] This utility model relates to the field of methods or mechanical technology specifically applicable to the manufacture of tubular products, and particularly to a rapid tensioning component for a concrete pile tensioning machine. Background Technology

[0002] A tensioning machine is a specialized device used in prestressed concrete construction to tension prestressed steel bars or strands. It is widely used in bridge, building, and water conservancy engineering. Chinese utility model patent, authorized announcement number "CN219276197U", discloses a prestressed tensioning machine for concrete pipe piles. This utility model utilizes the cooperation of slide rails and grooves to make the movement of the prestressed tensioning machine more stable, enabling it to slide back and forth without manual pushing, reducing labor intensity and saving time and effort. A cleaning mechanism removes dust, impurities, and spilled concrete from the slide rail surface, preventing concrete splashes from accumulating and affecting the use of the slide rail, further ensuring the stable movement of the tensioning machine. Adaptor slots of different diameters on the adapter allow for quick docking of pipe pile molds of different specifications with the tensioning machine, improving the docking efficiency between the tensioning machine and the pipe pile molds.

[0003] While the above-mentioned technical solution can clean up concrete splashes on the slide rail during use, the threaded rod driving the cleaning mechanism is also exposed to the outside, and the concrete splashes will also adhere to the outer surface of the threaded rod. Furthermore, the threaded rod does not have a self-cleaning structure, which makes it easy for concrete splashes to fall on the threaded rod and affect its transmission function, thus making it difficult to drive the tensioning machine to move. Therefore, we propose a rapid tensioning component for a concrete pile tensioning machine. Utility Model Content

This component can solve the problem that although it can clean up concrete splashes on the slide rail, the threaded rod driving the cleaning mechanism is also exposed to the outside, and the concrete splashes will also adhere to the outer surface of the threaded rod. Furthermore, the threaded rod does not have a self-cleaning structure, which makes it easy for concrete splashes to fall on the threaded rod and affect the transmission function of the threaded rod, thus making it difficult to drive the tensioning machine to move.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid tensioning assembly for a concrete pile tensioning machine, comprising:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a rapid tensioning assembly for a concrete pile tensioning machine, comprising:

[0027] Mounting base plate 1, with tensioning machine body 7 mounted on top of mounting base plate 1;

[0028] Tensioning structure, which is located on mounting base plate 1;

[0029] The tensioning structure includes four fixed plates 3, two slide rails 4, a drive motor 2, a movable base 6, and two threaded rods 11. The four fixed plates 3 are all fixedly connected to the top of the mounting base 1. The two slide rails 4 are all fixedly connected to the opposite surfaces of the two fixed plates 3. The bottom of each slide rail 4 is provided with a limiting groove 12. The two threaded rods 11 are rotatably connected to the inside of the corresponding limiting groove 12. The drive motor 2 is fixedly mounted on the corresponding fixed plate 3. The output end of the drive motor 2 rotatably extends into the inside of the corresponding slide rail 4 and is fixedly connected to the corresponding threaded rod 11. The outer surface of each of the two threaded rods 11 is threaded with a limiting slider 10. The two limiting sliders 10 are slidably connected to the inside of the corresponding limiting groove 12. The two limiting sliders 10 are fixedly connected to the inside of the movable base 6. The movable base 6 has a "C" shaped structure, and the two limiting sliders 10 have an "L" shaped structure.

[0030] The tensioning structure also includes a protective cover 9, two bevel gears 14, two bevel gears 15, and a linkage shaft 13. The ends of the two threaded rods 11 away from the drive motor 2 rotatably pass through the corresponding fixing plates 3 and are fixedly connected to the corresponding bevel gears 15. The protective cover 9 is fixedly connected to one side of the mounting base plate 1. The linkage shaft 13 is rotatably connected inside the protective cover 9. The two bevel gears 14 are fixedly sleeved on the outer surface of the linkage shaft 13. The two bevel gears 14 are meshed with the corresponding bevel gears 15.

[0031] The top of the movable base 6 is fixedly connected to the mounting base 8. The tensioning machine body 7 is fixedly installed on the top of the mounting base 8. One end of the tensioning machine body 7 is threadedly connected to the adapter 16. The adapter 16 has an adapter groove on the side away from the tensioning machine body 7. Two scraper plates 5 are bolted to both sides of the movable base 6. All four scraper plates 5 are slidably sleeved on the outer surface of the corresponding slide rail 4.

[0032] Furthermore, when using the device, the drive motor 2 is started, and the drive motor 2 drives the corresponding threaded rod 11 to rotate in the limiting slide groove 12. Since the limiting slider 10 is threadedly sleeved on the threaded rod 11 and slidably connected to the limiting slide groove 12, the rotation of the threaded rod 11 will drive the limiting slider 10 to move horizontally under the guidance inside the limiting slide groove 12. Since the bevel gear 14 at both ends of the linkage shaft 13 meshes with the bevel gear 15 at the end of the threaded rod 11, the threaded rods 11 on both sides rotate synchronously, so that the two limiting sliders 10 can move synchronously, thereby facilitating the movement of the moving base 6 along the slide rail 4, thereby facilitating the alignment of the tensioning machine body 7 with the tensioning position of the concrete pile.

[0033] After the mobile base 6 is moved to the target position, the tensioning machine body 7 is fixed to the top of the mobile base 6 by the mounting seat 8. According to the specifications of the concrete pile, the corresponding size of the adapter 16 is selected and threaded to the front end of the tensioning machine body 7. The adapter groove is used to quickly connect with the prestressing tendon. The tensioning machine body 7 is started to apply tension to the prestressing tendon and complete the tensioning operation.

[0034] During the movement of the mobile base 6, the scraper plates 5 bolted to both sides slide along the surface of the slide rail 4 to remove concrete residue, dust and other debris from the slide rail 4, preventing debris from accumulating and affecting the smooth sliding of the slide rail 4. The protective cover 9 protects the linkage shaft 13 and the bevel gear set, preventing debris from entering the transmission mechanism during the tensioning process and ensuring the safe operation of the equipment.

[0035] By engaging the linkage shaft 13 with the bevel gear set, the threaded rods 11 on both sides are forced to rotate synchronously, ensuring that the tensioning machine body 7 can move stably. At the same time, by setting the threaded rods 11 in the limiting groove 12, concrete is prevented from splashing onto the threaded rods 11. The scraper 5 can effectively remove concrete splashes from the surface of the slide rail 4, avoiding excessive wear on the slide rail surface, thus facilitating the movement of the tensioning machine.

[0036] Structural Description: Mounting Base Plate 1: Serves as the mounting foundation for the entire rapid tensioning assembly, providing a stable support platform for other components;

[0041] The movable base 6 has a "C" shaped structure and is connected to the threaded rod 11 and the slide rail 4 through the limiting slider 10. Under the drive of the drive motor 2, it can move horizontally along the slide rail 4 and drive the tensioning machine body 7 to the designated position.

[0042] The main body 7 of the tensioning machine is fixedly installed on the top of the mounting base 8. It is the core component for tensioning concrete piles. It is connected to the prestressing tendons through the adapter 16 and applies tension to complete the tensioning operation.

[0045] Limiting slider 10: It has an "L" shaped structure, is threaded onto the threaded rod 11 and is slidably connected to the limiting slide groove 12. When the threaded rod 11 rotates, it moves horizontally under the guidance of the limiting slide groove 12, thereby driving the moving base 6 to move.

[0046] Threaded rod 11: Rotatably connected inside the corresponding limiting slide groove 12, one end is fixedly connected to the output end of the drive motor 2, and the other end is fixedly connected to the bevel gear 15. It drives the limiting slider 10 to move by rotating.

[0047] Limiting groove 12: It is formed at the bottom of the two slide rails 4 to provide a sliding track for the limiting slider 10, restrict the movement direction of the limiting slider 10, and ensure that it can only move in a straight line;

[0048] Linkage shaft 13: Rotatably connected inside the protective cover 9, it meshes with the bevel gear 15 at the ends of the two threaded rods 11 through two bevel gears 14 to achieve synchronous rotation of the threaded rods 11 on both sides;

[0049] Bevel gear 14: It is fixedly sleeved on the outer surface of the linkage shaft 13 and meshes with the corresponding bevel gear 15 to transmit the rotation of the linkage shaft 13 to the threaded rod 11, so that the threaded rods 11 on both sides rotate synchronously.

[0050] Bevel gear 15: It is fixedly connected to the end of the corresponding threaded rod 11 away from the drive motor 2, and meshes with bevel gear 14 to realize the power transmission between the threaded rod 11 and the linkage shaft 13.
