Description
Technical Field
[0001] This utility model relates to the field of prestressing tensioning technology, and in particular to a high-efficiency prestressing tensioning device for pipe pile manufacturing. Background Technology
[0002] Pipe piles are structural columns used to bear large loads and support soil. They are widely used in building construction, road construction, bridge construction, etc. They are mainly made of concrete, steel bars or other materials, and usually have hollow rectangular or circular cross sections. They have excellent compressive and bending strength, as well as good durability, corrosion resistance and seismic resistance. The manufacturing process is divided into steel bar processing, pre-cast concrete and prestressing tensioning, vibration treatment and pipe pile curing.
[0003] Currently, when performing prestressing tensioning on pipe piles, they are generally placed on a support and connected to the pipe pile ends by bolts via a pulling block. Then, a hydraulic cylinder or hydraulic pump is used to apply tension to the pulling block, causing it to move the bolts away from the pipe pile, thus subjecting the pipe pile to tensile force and achieving the prestressing effect. Finally, the pipe pile is tightly fixed by tightening nuts to ensure that it reaches the expected prestressing state. However, in actual operation, due to differences in pipe pile specifications, their diameters may vary. Since the support and prestressing tensioning structure are integrated, when pipe piles of different diameters are placed on the support, the ends of the pipe pile and the prestressing tensioning structure may not be on the same horizontal line, leading to difficulties in the operation.

[0030] like Figures 1 to 6 As shown in the figure, this embodiment provides a high-efficiency prestressed tensioning device for pipe pile manufacturing. This high-efficiency prestressed tensioning device for pipe pile manufacturing includes a base 1 and a support 2. A lifting component and a connecting component are installed on the base 1. The support 2 is located on the top of the lifting component. Both the lifting component and the connecting component are provided in two sets. The two sets of lifting components are located inside the two sets of connecting components.
[0031] The lifting component includes a side guide plate 3 movably connected to the top of the base 1. There are two sets of side guide plates 3, which correspond to each other. The interior of each set of side guide plates 3 is provided with a guide groove 4, a first positioning groove 5, and a second positioning groove 6. The guide groove 4 is inclined, and the first positioning groove 5 and the second positioning groove 6 are both horizontal. The first positioning groove 5 and the second positioning groove 6 are located at the two ends of the guide groove 4, respectively. The guide groove 4, the first positioning groove 5, and the second positioning groove 6 are connected internally and form a Z-shape. The first positioning groove 5 is located at the top of the second positioning groove 6, which facilitates the positioning operation of the lifting shaft 7.
[0032] The second positioning groove 6 is internally connected to a lifting shaft 7. Both ends of the lifting shaft 7 pass through the second positioning groove 6 and two sets of side guide plates 3. The outer surface of the lifting shaft 7 is movably fitted with connecting blocks 8. The connecting blocks 8 are arranged in pairs and correspond to each other. The top of the multiple sets of connecting blocks 8 is fixedly connected to a bearing plate 9. The bracket 2 is located on the top of the bearing plate 9 and is fixedly connected to it. The bracket 2 is fixed in pairs on the two sets of bearing plates 9 respectively, which can make the pipe pile more stably installed on the bracket 2. When the bearing plate 9 is not raised, the lifting shaft 7 is located in the second positioning groove 6.
[0033] Guide blocks 10 are fixedly connected to the inner sides of the two sets of side guide plates 3. The two sets of side guide plates 3 are connected by guide blocks 10. Rollers 11 are installed on the outer surface of the lifting shaft 7. The rollers 11 are arranged in pairs and correspondingly, and are located inside the two sets of connecting blocks 8. The rollers 11 are located on the surface of the guide blocks 10. The internal shape of the guide blocks 10 is adapted to the guide groove 4, the first positioning groove 5 and the second positioning groove 6, which can facilitate the lifting operation of the lifting shaft 7, and at the same time reduce the load of the side guide plates 3 on the lifting shaft 7, so that the lifting shaft 7 can carry out the lifting operation more stably.
[0034] The bottom of the guide block 10 is provided with a guide groove 12, and a guide strip 13 adapted to the guide groove 12 is fixedly connected to the base 1, which can make the guide block 10 and the side guide plate 3 move more stably.
[0035] Telescopic rods 15 are fixedly connected to the base 1. The telescopic rods 15 are evenly distributed at the four corners of the support plate 9. The other end of the multiple sets of telescopic rods 15 are fixedly connected to the support plate 9, which can make the support plate 9 more stable during the lifting process.
[0036] A bidirectional electric push rod 16 is installed on the base 1. The output end of the bidirectional electric push rod 16 is fixedly connected to two sets of guide blocks 10. A positioning frame 17 is installed on the bidirectional electric push rod 16. There are two sets of positioning frames 17, which correspond to each other. Both sets of positioning frames 17 are fixedly connected to the base 1, which can fix the bidirectional electric push rod 16. The bidirectional electric push rod 16 is located between the two sets of lifting parts, which facilitates the synchronous lifting and lowering of the two sets of bearing plates 9, so as to facilitate the installation of pipe piles of different diameters and keep them horizontal with the connecting parts.
[0037] The connector includes connecting frames 18 located at both ends of the base 1. A screw 19 is installed inside the connecting frame 18. A pulling block 20 is threaded onto the screw 19. A moving block 21 is fixedly connected to the bottom of the connecting frame 18. A base plate 22 is fixedly connected to the bottom of the moving block 21. The base plate 22 extends into the interior of the base 1 and is movably connected thereto. A hydraulic cylinder is installed at the other end of the connecting frame 18 to facilitate the movement of the screw 19.
[0038] A dual-axis motor 25 is fixedly connected inside the base 1. Each output end of the dual-axis motor 25 is fixedly connected to a lead screw 23. Both sets of lead screws 23 are located inside the two sets of base plates 22 and are threadedly connected to them. The lead screws 23 are located inside the base 1 and are rotatably connected to it. At the same time, the lead screws 23 are located on one side of the base plate 22.
[0039] The other end of the base plate 22 is slidably connected to a slide rod 24, which corresponds to the lead screw 23. The slide rod 24 is located inside the base 1 and is fixedly connected to it, which can ensure the stability of the connecting frame 18 when it moves.
[0040] In use, by placing the pipe pile on the support 2 and activating the bidirectional electric push rod 16 to move the two sets of guide blocks 10 away from each other, the side guide plate 3 is moved towards the connecting frame 18. During this process, the side guide plate 3 moves the guide groove 4, the first positioning groove 5 and the second positioning groove 6 simultaneously. The lifting shaft 7 will rise sequentially inside the second positioning groove 6, the guide groove 4 and the first positioning groove 5 as the side guide plate 3 moves, until the lifting shaft 7 is located inside the first positioning groove 5 by the movement of the guide groove 4. This allows the bearing plate 9 to push the support 2 up, thus adjusting the height of the support 2.
[0041] Then, the dual-axis motor 25 can be started to make the two sets of lead screws 23 rotate synchronously. As the lead screws 23 rotate, the two sets of base plates 22 can be brought closer to each other, which in turn drives the two sets of connecting frames 18 to be brought closer to each other until the screws 19 inside them contact the bolts at both ends of the pipe pile. Then, by rotating the moving block 21, it is moved from the screw 19 to the bolt, and the bolt is connected to the screw 19. After that, the hydraulic cylinder on the other side of the connecting frame 18 drives the screw 19 to move away from the pipe pile, and the bolts at both ends of the pipe pile are moved by the pulling block 20 to complete the purpose of prestressing tensioning.
[0042] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
