Description

Technical Field

[0001] This utility model relates to a prestressed pipe pile processing method, and in particular a prestressed pipe pile cutting device. Background Technology

[0002] Prestressed concrete pipe piles are a commonly used building material, mainly used in the piling construction of various building foundations. They utilize high-strength concrete materials and steel strands (or wires) to apply prestress during manufacturing, thereby improving their load-bearing capacity and compressive strength.

[0003] During the manufacturing process of prestressed concrete pipe piles, a pipe pile cutting device is used depending on the length of the pile. Cutting methods include hydraulic cutting and plasma cutting. The main cutting methods are as follows: Diamond circular saw blade cutting: suitable for cutting various types of prestressed concrete components, with good cutting effect and minimal damage to the concrete. Hydraulic cutting: uses high-pressure water jets for cutting, with fast cutting speed and minimal environmental pollution, suitable for large-scale projects. Arc cutting: suitable for cutting thick prestressed concrete pipe piles, with fast cutting speed, but prone to causing thermal damage to the pile body.

[0004] Currently, prestressed concrete pipe pile cutting devices use a clamping assembly to fix the pipe pile to the outside. Then, based on the thickness of the pipe pile, a cutting assembly with length adjustment function is used to adjust the cutting depth. A height adjustment function is used to achieve cuts of different lengths on the pipe pile surface. However, this type of cutting device is inconvenient to adjust the cutting angle, easily causing blade deviation and making it difficult to achieve a smooth cut at the end of the pipe pile. For these reasons, it is necessary to design a prestressed concrete pipe pile cutting device that can rotate to cut the pipe pile, increasing the smoothness of the cut. Utility Model Content

[0005] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a prestressed pipe pile cutting device, which realizes that the prestressed pipe pile cutting device can perform circumferential rotation cutting of the pipe pile, thereby improving cutting stability and increasing the flatness of the pipe pile cutting.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A prestressed concrete pipe pile cutting device includes two pile clamping plates connected opposite to each other, a depth adjustment component disposed on the pile clamping plates, a length adjustment component perpendicularly disposed on one side of the depth adjustment component, and a cutting component disposed on the telescopic end of the length adjustment component. Rollers are rotatably disposed on the inner side of the pile clamping plates, and a sliding plate is slidably disposed on the outer side of the pile clamping plates, with the depth adjustment component connected to the sliding plate. A balancing component is fixedly disposed on the outer side of the pile clamping plates. The balancing component includes a support component, an adjusting component disposed on the support component, and a limiting component disposed on the adjusting component, for stabilizing the position of the cutting device and increasing the flatness of the pipe pile cutting.

[0008] Preferably, the pile clamping plate has a hollow structure, and multiple central rollers are rotatably arranged inside the pile clamping plate. A rolling shaft is arranged on the side of the sliding plate near the pile clamping plate, and the rolling shaft is located in the pile clamping plate. The rolling shaft is distributed parallel to the central rollers.

[0009] Preferably, a positioning rod is rotatably provided on the side of the roller near the pile plate, and the roller is distributed parallel to the central roller shaft.

[0010] Preferably, the support assembly includes two support plates bolted to the pile plate, and a hinge is provided between the two support plates.

[0011] Preferably, one of the support plates has a slot that mates with the adjusting member. The adjusting member includes an elastic sleeve that is fixedly connected to the slot. A plurality of cylindrical springs are fixedly arranged in a ring on the inner side of the elastic sleeve. The ends of the plurality of cylindrical springs are fixedly provided with the same support ring, and the support ring is connected to the limiting member.

[0012] Preferably, the limiting member includes a stepped spring fixed to one side of the adjusting member, and the same support rod is slidably arranged between the stepped spring and the adjusting member. One end of the support rod is provided with a motor, and the other end of the support rod is provided with a through end connected to the motor.

[0013] Preferably, the pile clamping plate has an arc-shaped structure, and the ends of the two pile clamping plates are bolted together.

[0014] Compared with existing technologies, the prestressed pipe pile cutting device provided by this utility model can perform circumferential rotational cutting of the pipe pile, increasing the cutting stability and the flatness of the cutting end face. Specifically, the rollers on the inner side of the pile clamping plate and the sliding rotating plate on the pile clamping plate facilitate the circumferential cutting of the pipe pile surface while the pile clamping plate is limited to the outer surface of the pipe pile. Furthermore, the angle rotation of the two pile clamping plates on the pipe pile facilitates the adjustment of the position of the cutting end on the device, which is convenient for cutting the surface of the pipe pile on the other side. This allows the cutting device to perform sliding and rotational cutting simultaneously, increasing the flatness of the pipe pile end, preventing cut deviation, and improving the cutting flatness of the pipe pile end.

[0015] Furthermore, the use of the balancing component on the clamping plate allows the balancing component to balance the weight on one side of the cutting component while simultaneously limiting and fixing the other side, increasing the connection strength between the clamping pile and the pipe pile, facilitating the cutting device to cut pipe piles on different processing platforms, ensuring the stability of the cutting edge, and increasing the cutting flatness of the device.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] As attached Figure 1 and appendix Figure 2 As shown in the figure, the prestressed concrete pipe pile cutting device provided in this embodiment of the present invention is used to separately cut the entire section of the pipe pile and the concrete. During the cutting process, the device uses arc-shaped clamping plates 1, with two clamping plates 1 fitted onto both sides of the pipe pile, and secured with bolts passing through the two clamping plates 1 and tightened with nuts. Next, the depth adjustment component 11 is adjusted to bring the cutting disc on the cutting component 13 into contact with the surface of the pipe pile. Then, according to the position of the pipe pile to be cut, the length adjustment component 12 is adjusted so that the cutting edge of the cutting disc is positioned at the cutting position of the pipe pile. When cutting the pipe pile according to its thickness, the cutting component 13 drives the rotation of the cutting disc, and the depth adjustment component 11 drives the cutting disc to move towards the pipe pile, facilitating pipe pile cutting to different depths. After the cutting disc enters the pipe pile, the roller 22, which is rotatably mounted on the inner side of the clamping plate 1, can adjust the angle of the clamping plate 1. This allows the cutting disc to rotate around the pipe pile, enabling it to slide on the pile. This facilitates circumferential cutting on the outer side of the pipe pile, prevents cut deviation, and increases the flatness of the cut end. Furthermore, a sliding plate 23, connected to the depth adjustment component 11, is slidably mounted on the outer side of the clamping plate 1, facilitating the sliding cutting of the cutting component 13, increasing its cutting flexibility, reducing the adjustment angle of the clamping plate 1, and improving the cutting efficiency of the pipe pile. During the cutting process, a balancing component on the outer side of the clamping plate 1 can be used to increase the connection strength between the cutting device and the processing platform or the pipe pile, further increasing the flatness of the cut end. The balancing component includes a support assembly 3, an adjusting member 4 mounted on the support assembly 3, and a limiting member 5 mounted on the adjusting member 4. The support assembly 3 is used to connect the pile plate 1 to the pipe pile. The adjusting member 4 is the end that fits with the pipe pile. The limiting member 5 is the limiting structure of the balancing component, which can limit the side of the cutting device that has not been processed, thereby improving the positional stability of the cutting device.

[0027] It is worth noting that, for example Figure 2 and 3As shown, the clamping plate 1 has a hollow structure, and multiple central rollers 21 are rotatably arranged inside the clamping plate 1 to provide conditions for the sliding connection between the sliding plate 23 and the clamping plate 1. A rolling shaft 231 is arranged on the side of the sliding plate 23 near the clamping plate 1. The rolling shaft 231 is eccentrically positioned between the clamping plate 1 and the central rollers 21. Through the rotational characteristics of the rolling shaft 231 and the central rollers 21, the sliding plate 23 can be easily slidably used, which facilitates the cutting of the cutting device at different angles and makes the sliding cutting of the cutting device convenient.

[0028] To further facilitate the annular cutting of the cutting device, the operating angle of the clamping plate 1 is adjusted, such as... Figure 3 As shown, a roller 22 can be installed on the inner side of the pile clamping plate 1. The roller 22 is rotatably mounted on the pile clamping plate 1 via a positioning rod 221 on one side close to the pile clamping plate 1. The roller 22 is distributed parallel to the central roller 21. When the angle of the pile clamping plate 1 is adjusted, the angle of the pile clamping plate 1 can be adjusted by rotating the roller 22, thereby increasing the angle adjustment of the pile clamping plate 1 and facilitating the cutting of different sides of the pipe pile.

[0029] In some embodiments, the support assembly 3 may use two support plates 31, such as Figure 1 As shown, a hinge 32 is provided between the two support plates 31. The angle between the two plates is adjusted by tightening or loosening the bolts on the hinge 32 and the support plates 31. One end of the support plate 31 is rotatably connected to the clamping plate 1 with bolts, and the end of the other support plate 31 is used to fix the adjusting component 4. The clamping plate 1 is connected to the pipe pile or processing platform through the bracket assembly 3, which facilitates the limiting component 5 to be limited on the pipe pile or processing platform, and limits and fixes the other side of the cutting device, increasing the processing stability of the cutting device.

[0030] To better facilitate the positioning and fixing of the limiting member 5 to the pipe pile or processing platform, in some embodiments, the support plate 31 can be configured as an elastic support to assist in fixing the limiting member 5, such as... Figure 4 and 5 As shown, a slot for mounting the adjusting member 4 is formed on the end support plate 31 of the bracket assembly 3. The adjusting member 4 includes an elastic sleeve 43 disposed in the slot. Multiple cylindrical springs 41 are circumferentially fixed to the inner side of the elastic sleeve 43. The ends of the multiple cylindrical springs 41 are fixed to the same support ring 42 for connection with the limiting member 5. This achieves elastic support between the bracket assembly 3 and the limiting member 5, facilitating the limiting use of the limiting cutting device in different processing environments.

[0031] To facilitate the positioning and fixing of the limiting component 5 and improve the limiting speed, the limiting component 5 can be fixed by using a motor 53 to drive the through end 54 to drill into the pipe pile or processing platform. Figure 5As shown, the limiting component 5 includes a table-shaped spring 51 fixed to one side of the adjusting component 4. A common support rod 52 slides between the table-shaped spring 51 and the adjusting component 4. A motor 53 is mounted at one end of the support rod 52, and a through-end 54 connected to the motor 53 is mounted at the other end. During processing, the motor 53 drives the through-end 54, facilitating its rotation. The support rod 52 then pushes the through-end 54, allowing it to be screwed into the pipe pile or processing platform, ensuring the stability of the cutting device's position. After the cutting device has cut one side of the pipe pile, the reverse rotation of the motor 53 can be used to unscrew the through-end 54 from the pipe pile or processing platform, adjusting the position of the clamping plate 1 on the pipe pile. Then, the balancing component is used again to limit the position of the cutting device, ensuring a circular cut of the pipe pile and increasing the flatness of the cut end.

[0032] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
