Description

Technical Field

[0001] This utility model relates to the field of square pile processing equipment, specifically a prestressed square pile prestressing tendon tensioning platform. Background Technology

[0002] Prestressed tendons are usually composed of single or bundled steel wires, strands, or bars. In pre-tensioning production, threaded bars, indented wires, or strands are generally used to ensure reliable bonding with concrete. In post-tensioning production, smooth bars, smooth wires, or strands are used, and they are divided into unbonded prestressed tendons and bonded prestressed tendons.

[0003] When processing prestressed square piles, the reinforcing bars need to be tensioned first, and then the concrete needs to be poured. After the concrete has cured to a certain extent, the tension of the reinforcing bars is released, and the prestressed square pile is then completed. However, the pouring point is fixed at this time, so the concrete needs a certain amount of time to flow until it is level, which prolongs the processing time of the square pile and reduces the processing efficiency. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a prestressed square pile prestressed tendon tensioning platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prestressed square pile prestressed tendon tensioning platform, comprising a fixed platform, a tensioning mechanism for facilitating the tensioning of reinforcing bars provided on the outer side of the fixed platform, and a pouring mechanism for facilitating concrete pouring provided at the top of the fixed platform. The pouring mechanism includes a fixed plate, a first screw, a positioning rod, a steering assembly, a motor, a movable plate, and a pouring pipe. The fixed plate is embedded and fixed at the top of the fixed platform. The motor is fixed on one side of the fixed plate. The first screw is fixed at the output end of the motor. The other side of the first screw is movably embedded in an adjacent fixed plate. The positioning rod is fixed between the fixed plates. The steering assembly is located on the outer side of the positioning rod. The movable plate is threaded onto the outer side of the first screw. The pouring pipe is embedded and fixed at the center of the movable plate.

[0006] Preferably, the steering assembly includes a movable ring, a trigger switch, and a second screw. The movable ring is movably sleeved on the outside of the positioning rod. The second screw is threaded through and disposed at the top of the movable ring. The trigger switch is embedded and fixed at the top of the movable ring. In use, the concrete discharge pipe is fixed to the top of the pouring pipe through a connecting valve. Then, the motor is started, and the motor drives the first screw to rotate. This causes the movable plate to move along the first screw, moving the pouring pipe and thus changing the concrete pouring point, making the concrete more evenly spread inside the molding mold. This facilitates rapid leveling of the concrete and improves the processing efficiency of the square column. When one side of the movable plate contacts the trigger switch on the other side, the motor rotates in the opposite direction, causing the movable plate to move in the opposite direction and reset. This movement is repeated to ensure uniform pouring. At the same time, the movable ring moves along the positioning rod, and then the second screw is rotated to fix the position of the movable ring. This allows for easy adjustment of the trigger switch position and the spacing between the trigger switches, making it suitable for pouring molds of different lengths.

[0007] Preferably, the tensioning mechanism includes connecting reinforcing bars, a tensioning table, and a hydraulic rod. Two sets of connecting reinforcing bars are provided: one set is embedded and fixed to one side of the fixed platform, and the other set is embedded and fixed to the tensioning table. One side of the connecting reinforcing bars embedded and fixed to the tensioning table is movably inserted into the fixed platform. The hydraulic rod is fixed to one side of the fixed platform, and the tensioning table is installed on one side of the hydraulic rod. In use, the reinforcing bar to be tensioned is fixed between the connecting reinforcing bars using a reinforcing bar connector. Then, the hydraulic rod is activated to move the tensioning table, thereby tensioning the reinforcing bar to be tensioned through the connecting reinforcing bars, and then casting is performed.

[0008] Preferably, four fixing plates are provided, with two plates forming a group, and the two groups are symmetrically fixed on both sides of the top of the fixing base.

[0009] Preferably, the other side of the movable plate is movably sleeved on the outside of the positioning rod.

[0010] Preferably, the trigger switch is electrically connected to the motor to facilitate control of the motor's direction of rotation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model fixes the concrete discharge pipe to the top of the pouring pipe through a connecting valve, and then starts the motor. The motor drives the first screw to rotate, so that the movable plate moves along the first screw, which in turn moves the pouring pipe. This changes the concrete pouring point, so that the concrete is more evenly spread inside the forming mold, which facilitates the rapid leveling of the concrete and improves the processing efficiency of the square column.

[0013] 2. When one side of the movable plate contacts the trigger switch on the other side, the motor rotates in a different direction, causing the movable plate to move in the opposite direction and reset. This movement is repeated to ensure uniform pouring. At the same time, the movable ring moves along the positioning rod, and then the second screw is rotated to fix the position of the movable ring. This makes it easy to adjust the position of the trigger switch, thereby facilitating the adjustment of the spacing between the trigger switches and making it suitable for pouring molds of different lengths.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a prestressed square pile prestressed tendon tensioning platform, including a fixed platform 1. The fixed platform 1 has a tensioning mechanism on its outer side for easy tensioning of the reinforcing bars, and a pouring mechanism at the top of the fixed platform 1 for easy pouring of concrete. The pouring mechanism includes a fixed plate 6, a first screw 8, a positioning rod 10, a steering assembly, a motor 7, a movable plate 9, and a pouring pipe 11. The fixed plate 6 is embedded and fixed at the top of the fixed platform 1. There are four fixed plates 6, with two in each group, and the two groups are symmetrically fixed on both sides of the top of the fixed platform 1. The motor 7 is fixed to one side of the fixed plate 6 by a mounting bracket. The first screw 8 is fixed to the output end of the motor 7 by a coupling. The other side of the first screw 8 is movably embedded in the adjacent fixed plate 6. The positioning rod 10 is welded and fixed between the fixed plates 6. The steering assembly is on the outside of the positioning rod 10. The movable plate 9 is threaded onto the outside of the first screw 8. The other side of the movable plate 9 is movably sleeved onto the outside of the positioning rod 10. The pouring pipe 11 is embedded and fixed at the center of the movable plate 9.

[0020] The steering assembly includes a movable ring 12, a trigger switch 13, and a second screw 5. The movable ring 12 is movably sleeved on the outside of the positioning rod 10. The second screw 5 is threaded through the top of the movable ring 12. The trigger switch 13 is embedded and fixed to the top of the movable ring 12 and is electrically connected to the motor 7 for easy control of the motor 7's direction. In use, the concrete discharge pipe is fixed to the top of the pouring pipe 11 through a connecting valve. Then, the motor 7 is started, and the motor 7 drives the first screw 8 to rotate. This causes the movable plate 9 to move along the first screw 8, thereby moving the pouring pipe 11 and changing the direction of the concrete discharge. The soil pouring point allows the concrete to be laid more evenly inside the forming mold, facilitating rapid leveling of the concrete and thus improving the processing efficiency of the square column. When one side of the movable plate 9 contacts the trigger switch 13 on the other side, the motor 7 changes direction, driving the movable plate 9 to move in the opposite direction and reset. This movement is repeated to ensure even pouring. At the same time, the movable ring 12 moves along the positioning rod 10, and then the second screw 5 is rotated to fix the position of the movable ring 12. This makes it easy to adjust the position of the trigger switch 13, thereby facilitating the adjustment of the spacing between the trigger switches 13 and making it suitable for pouring molds of different lengths.

[0021] The tensioning mechanism includes connecting steel bars 4, a tensioning table 3, and a hydraulic rod 2. There are two sets of connecting steel bars 4. One set of connecting steel bars 4 is embedded and fixed on one side of the fixed base 1, and the other set is embedded and fixed on the tensioning table 3. One side of the connecting steel bars 4 embedded and fixed on the tensioning table 3 is movably inserted into the interior of the fixed base 1. The hydraulic rod 2 is fixed to one side of the fixed base 1 by a mounting bracket. The tensioning table 3 is installed on one side of the hydraulic rod 2 by bolts. In use, the steel bar to be tensioned is fixed between the connecting steel bars 4 through the steel bar connector. Then, the hydraulic rod 2 is activated to move the tensioning table 3, so that the steel bar to be tensioned can be stretched and tensioned through the connecting steel bars 4, and then the pouring can be carried out.

[0022] Working principle: During use, the concrete discharge pipe is fixed to the top of the pouring pipe 11 via the connecting valve. Then, the motor 7 is started, which drives the first screw 8 to rotate. This causes the movable plate 9 to move along the first screw 8, moving the pouring pipe 11 and changing the concrete pouring point. This makes the concrete more evenly spread inside the forming mold, facilitating rapid leveling of the concrete and improving the processing efficiency of the square column. When one side of the movable plate 9 contacts the trigger switch 13 on the same side, the motor 7 changes direction, causing the movable plate 9 to move in the opposite direction and reset. This movement is repeated to ensure even pouring. At the same time, the movable ring 12 moves along the positioning rod 10, and then the second screw 5 is rotated to fix the position of the movable ring 12. This allows for easy adjustment of the position of the trigger switch 13 and the spacing between the trigger switches 13, making it suitable for pouring molds of different lengths.
