Description

Technical Field

[0001] The utility model relates to the technical field of prestressed pipe piles, and particularly relates to a cutting device for prestressed pipe piles. Background Technique

[0002] Prestressed pipe piles are concrete piles made through prestressing technology, with high load-bearing capacity and good stability, and are widely used in various foundation projects. The manufacturing process of prestressed pipe piles includes assembling prestressed steel bars and concrete pipe piles together, and prestressing the prestressed steel bars through prestressing technology to keep them in a tensioned state before the concrete hardens, further improving the load-bearing capacity and stability of the pipe piles. When prestressed pipe piles are in use, they need to be cut. Currently, there are various cutting devices for prestressed pipe piles on the market, but there are still some drawbacks.

[0003] The existing cutting devices for prestressed pipe piles can only clamp one pipe pile at a time through the clamping parts for cutting, which will greatly reduce the cutting efficiency of the pipe piles. At the same time, the cutting of the pipe piles can only be carried out at one position and cannot cut pipe piles of different sizes, lacking adjustability. In addition, the clamping parts are only fixed above the pipe piles, and there are problems such as unstable clamping. For example, the Chinese utility model patent with the authorization announcement number CN113718770A discloses a cutting device for prestressed pipe piles, which includes a pile clamping assembly and a cutting assembly. The pile clamping assembly includes a connecting plate, connecting rods, and clamping parts. The connecting plate is used to connect with the end plate of the prestressed pipe pile. There are at least two connecting rods, and the connecting rods are rotatably connected to the connecting plate. One ends of the connecting rods are close to each other and are connected with a rotation driving part for making the connecting rods rotate around the connecting plate. The other ends of the connecting rods are all connected with the clamping parts, and the clamping parts are used to clamp the prestressed pipe piles. The cutting assembly is connected with the connecting plate and is slidably connected with the connecting plate, and the sliding direction is parallel to the axial direction of the prestressed pipe pile. This application has the effect of improving the safety and convenience of the operator in the process of cutting prestressed pipe piles. However, this device has the problems that it can only clamp one pipe pile at a time through the clamping parts for cutting, which will greatly reduce the cutting efficiency of the pipe piles. At the same time, the cutting of the pipe piles can only be carried out at one position and cannot cut pipe piles of different sizes, lacking adjustability. In addition, the clamping parts are only fixed above the pipe piles, and there are problems such as unstable clamping. Therefore, we propose a cutting device for prestressed pipe piles to solve the problems raised above. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0031] Example 1: To solve the problems existing in the prior art, this embodiment adopts the following technical solution. A prestressed pipe pile cutting device is provided with a base 1 and a multi-cutting mechanism at one time, which is arranged above the base 1. A plurality of placing grooves 2 are equidistantly opened above the base 1. The pipe pile body 3 is placed inside the placing groove 2; a clamping mechanism is arranged outside the pipe pile body 3. The pipe pile body 3 is firmly limited by using the limiting plate 4 and the clamping block 5 so that it will not move during cutting; a multi-fixed-point moving cutting mechanism is arranged symmetrically before and after inside the base 1 and above the inside of the base 1. A plurality of positioning grooves 15 are equidistantly arranged below the pipe pile body 3. The support frame 11 can move according to the position of the positioning groove 15 to cut the pipe pile body 3. First, place the pipe pile body 3 into the placing groove 2 opened in the base 1, and turn on the electric telescopic rod 9. The electric telescopic rod 9 is arranged at the connection between one side of the fixed block 7 and the middle part of the clamping block 5. The fixed block 7 is fixed to the base 1. At the same time, a connecting rod 10 is fixedly connected above the clamping block 5, and the connecting rod 10 is also connected to the rotating plate 8 above the fixed block 7. That is, when the electric telescopic rod 9 is turned on, the clamping block 5 will be closely attached to the outside of the pipe pile body 3. In addition, a limiting plate 4 is arranged at the central symmetry of the pipe pile body 3, and the limiting plate 4 and the clamping block 5 will fix and limit the pipe pile body 3. Then turn on the motor 21 connected to the right side of the second pulley 20. The second pulley 20 will rotate. A connecting belt 19 is arranged between the second pulley 20 and the outer first pulley 18, and the first pulley 18 will also rotate. That is, the threaded rod 16 will rotate inside the base 1, and the support frame 11 installed with an external thread will move when the threaded rod 16 rotates. The support frame 11 can move according to the position of the positioning groove 15 opened above the base 1 to cut the pipe pile body 3.

[0032] The existing prestressed pipe pile cutting device can only cut one pipe pile at a time, which will greatly reduce the cutting efficiency of the pipe pile. As Figure 1 , Figure 5 and Figure 6 shown, the multi-cutting mechanism at one time includes placing grooves 2 equidistantly arranged above the inside of the base 1. The placing grooves 2 are divided into three parts above the base 1. The pipe pile body 3 is placed inside the placing groove 2. Secondly, cutting knives 14 are arranged corresponding to the upper part of the pipe pile body 3 one by one. Turn on the hydraulic rod 12, and the hydraulic rod 12 can push the support plate 13 and the cutting knife 14 installed at the output end to move downward. Then turn on the motor 21 on the right side of the middle part of the cutting knife 14 to make the cutting knife 14 rotate. When the cutting knife 14 touches the pipe pile body 3, the pipe pile body 3 can be cut, so that the device can cut multiple pipe pile bodies 3 at one time, greatly improving the cutting efficiency of the pipe pile body 3.

[0033] Example 2: In the existing device, the clamping mechanism is only fixed above the pipe pile, and there is instability in clamping and fixing the pipe pile. Therefore, in this embodiment, through the following technical solutions, as Figure 1 , Figure 4 and Figure 5 shown, the clamping mechanism includes a clamping block 5 closely attached to the outside of the pipe pile body 3. A support rod 6 is slidably installed inside the clamping block 5, and a fixing block 7 is provided in the middle of the support rod 6. The fixing block 7 is fixedly connected to the base 1. At the same time, an electric telescopic rod 9 is connected between one side of the fixing block 7 and the middle of the clamping block 5. At the same time, a connecting rod 10 is connected above the clamping block 5, and the connecting rod 10 is also connected to a rotating plate 8 rotatably arranged above the fixing block 7. That is, when the electric telescopic rod 9 is opened, the electric telescopic rod 9 can make the clamping block 5 slide back and forth outside the support rod 6, so that the clamping block 5 firmly adheres to the outside of the pipe pile body 3 to limit and fix the pipe pile body 3. Secondly, a limiting plate 4 is closely attached and arranged symmetrically at the center of the pipe pile body 3. The limiting plate 4 is fixedly installed on the base 1. That is, the limiting plate 4 and the clamping block 5 can prevent the pipe pile body 3 from shifting during cutting, improving the cutting accuracy of the pipe pile body 3.

[0034] Example 3: The existing device can only cut the pipe pile at one position and cannot cut pipe piles of different sizes. Therefore, in this embodiment, through the following technical solutions, as Figure 2 , Figure 3 and Figure 6 shown, the multi-fixed-point moving cutting mechanism includes threaded rods 16 symmetrically arranged before and after inside the base 1. A support frame 11 is threadedly connected to the outside of the threaded rod 16. At the same time, a first pulley 18 and a second pulley 20 are connected to the right side of the threaded rod 16. When the motor 21 on the right side of the second pulley 20 is turned on, the motor 21 will make the second pulley 20 rotate. Through the connection belt 19 arranged outside the second pulley 20 and the first pulley 18, that is, the first pulley 18 will also rotate. The first pulley 18 and the second pulley 20 will drive the threaded rod 16 to rotate together. Secondly, a fixed rod 17 is snap-connected inside the support frame 11. That is, when the threaded rod 16 rotates, the support frame 11 can slide left and right outside the threaded rod 16. Since a positioning groove 15 is opened above the inside of the base 1, the support frame 11 can move according to the position of the positioning groove 15, so that pipe pile bodies 3 of different lengths can be cut.
