[0048] The embodiment of the present application provides a novel horizontal cutter for the end of an obliquely driven pipe pile. The novel horizontal cutter for the end of an obliquely driven pipe pile of the present application is described in detail below with reference to the accompanying drawings.

[0049] Reference Figure 1 , showing a schematic diagram of the structure of a novel horizontal cutter for the end of an obliquely driven pile provided in an embodiment of the present application, referring to Figure 2 , shows a schematic diagram of the assembly of the clamp ring and the guide assembly provided in the embodiment of the present application, with reference to Figure 3 to Figure 4 , showing the assembly diagram of the arc-shaped clamp and the arc-shaped guide, referring to Figure 5 , shows a partial enlarged view of the first connection component provided in an embodiment of the present application, referring to Figure 6 , shows a partial enlarged view of the second connection assembly provided in an embodiment of the present application, referring to Figure 7 , showing a schematic diagram of the structure of the slide rail frame provided in an embodiment of the present application, referring to Figure 8 , showing a schematic structural diagram of the cutting assembly provided in an embodiment of the present application.

[0050] like Figure 1As shown, the present application provides a novel horizontal cutter for the end of an obliquely driven pipe pile, comprising: a clamping ring 1, a guide assembly 2 and a cutting assembly 3; the clamping ring 1 is used to be sleeved on the obliquely driven pipe pile 10, the clamping ring 1 has a first axis, and the first axis coincides with the axis of the obliquely driven pipe pile 10; the guide assembly 2 is arranged in the circumference of the clamping ring 1, and the guide assembly 2 is provided with an elliptical track, the track has a first center line, and the first center line is arranged at an angle to the first axis; the cutting assembly 3 is slidably connected to the guide assembly 2, and the cutting assembly 3 moves along the circumference of the track to cut the obliquely driven pipe pile 10, wherein the cutting direction of the cutting assembly 3 is perpendicular to the first center line, so that the obliquely driven pipe pile 10 after cutting has a horizontal cutting surface.

[0051] In the embodiment of the present application, on the one hand, since the clamp ring 1 and the guide assembly 2 are provided, and the first axis of the clamp ring 1 is set at an angle with the first center line of the guide assembly 2. In this way, when the clamp ring 1 is sleeved on the obliquely driven pipe pile 10, since the first axis of the clamp ring 1 is set at an angle with the first center line of the guide assembly 2, that is, when the clamp ring 1 is tilted, the guide assembly 2 can always be adjusted to a position parallel to the horizontal plane for subsequent horizontal cutting work. On the other hand, the guide assembly 2 is provided with an elliptical track, and the cutting assembly 3 is slidably connected to the guide assembly 2 and moves along the circumferential direction of the track, and the cutting direction of the cutting assembly 3 is perpendicular to the first center line. In this way, when the guide assembly 2 is parallel to the horizontal plane, the cutting assembly 3 can cut the end of the obliquely driven pipe pile 10 along the circumferential movement of the track in the horizontal direction, so that the obliquely driven pipe pile 10 after cutting has a horizontal cutting surface, thereby improving the flatness of the end surface of the obliquely driven pipe pile 10 and the cutting efficiency of the end of the obliquely driven pipe pile 10, which is beneficial to the subsequent construction of the pile cap.

[0052] It should be noted that, when the guide assembly 2 is arranged horizontally, that is, the first center line is arranged along the vertical direction, the angle between the first center line of the guide assembly 2 and the second axis of the clamp ring 1, that is, the angle between the axis of the obliquely driven pipe pile 10 and the vertical direction, is related to the degree of inclination of the obliquely driven pipe pile 10. Therefore, the embodiment of the present application does not limit the angle between the first center line and the second axis, and those skilled in the art can adjust it according to the actual situation of the obliquely driven pipe pile 10.

[0053] like Figures 2 to 4As shown, the novel obliquely driven pipe pile end horizontal cutter also includes a first connecting component 4 and a second connecting component 5; the first connecting component 4 and the second connecting component 5 are arranged at intervals along the circumference of the tightening ring 1, and are both located between the tightening ring 1 and the guide component 2, and the first connecting component 4 and the second connecting component 5 are both used to connect the tightening ring 1 and the guide component 2; wherein, the first connecting component 4 is provided with a slope adjusting member 43, and the slope adjusting member 43 is used to adjust the inclination of the tightening ring 1 relative to the guide component 2, so that the first center line and the first axis are arranged at a preset angle.

[0054] In the embodiment of the present application, on the one hand, since the first connecting component 4 and the second connecting component 5 are provided between the clamping ring 1 and the guide component 2, and the first connecting component 4 and the second connecting component 5 are provided at intervals along the circumference of the clamping ring 1, the clamping ring 1 and the guide component 2 can be reliably connected together. On the other hand, since the first connecting component 4 is provided with a slope adjustment member 43, the inclination of the clamping ring 1 relative to the guide component 2 can be adjusted, so that the first center line of the guide component 2 and the first axis of the clamping ring 1 are arranged at a preset angle.

[0055] It should be noted that the preset angle in the embodiment of the present application refers to the angle required for horizontal cutting of the obliquely driven pipe pile 10, and those skilled in the art can specifically set it according to the degree of inclination of the obliquely driven pipe pile 10. In addition, when the first connecting component 4 is not provided with an inclination adjustment member 43, that is, the first center line coincides with the first axis line, then the new obliquely driven pipe pile end horizontal cutter provided in the embodiment of the present application can also be used in the application scenario of vertical pipe pile cutting. In addition, the embodiment of the present application does not limit the specific setting positions of the first connecting component 4 and the second connecting component 5, and those skilled in the art can adjust them according to actual needs. In one embodiment, if Figure 1 As shown, the guide assembly 2 includes a first end and a second end relatively arranged along the long axis direction of the track, and the first connecting assembly 4 and the second connecting assembly 5 are relatively arranged, and are respectively located between the first end and the tight ring 1 and between the second end and the tight ring 1, which is beneficial to improve the connection reliability between the tight ring 1 and the guide assembly 2.

[0056] like Figure 5As shown, the first connecting component 4 also includes a first support 41 and a second support 42, the first support 41 is arranged on the side of the guide component 2 close to the tight ring 1, the second support 42 is arranged on the side of the tight ring 1 close to the guide component 2, and the second support 42 is provided with a slot 441; the inclination adjustment member 43 includes an adjusting screw 431, one end of the adjusting screw 431 is movably connected to the first support 41, and the preset position of the adjusting screw 431 is clamped in the slot 441, so that the first center line and the first axis maintain the preset angle.

[0057] In the embodiment of the present application, the first connecting assembly 4 includes a first support 41 and a second support 42, wherein the first support 41 is movably connected with an adjusting screw 431, and the second support 42 is provided with a clamping groove 441. In this way, by clamping the preset position of the adjusting screw 431 in the clamping groove 441, a reliable connection between the guide assembly 2 and the clamping ring 1 can be achieved, and the first center line of the guide assembly 2 and the first axis of the clamping ring 1 maintain a preset angle, so that the obliquely driven pipe pile 10 with a corresponding inclination degree has a horizontal cutting surface after cutting.

[0058] It should be noted that the preset position of the embodiment of the present application refers to the position where the first center line and the first axis maintain a preset angle after the adjusting screw 431 is engaged with the slot 441. It is understandable that the preset position of the adjusting screw 431, the preset angle between the first center line and the first axis, and the degree of inclination of the obliquely driven pipe pile 10 are corresponding. In addition, in order to make the adjusting screw 431 movably connected to the first support 41, the inclination adjustment member 43 of the embodiment of the present application also includes a connecting block 433, one end of the connecting block 433 close to the adjusting screw 431 is threadedly connected to the adjusting screw 431, and one end of the connecting block 433 away from the adjusting screw 431 is hinged to the first support 41.

[0059] Furthermore, two second supports 42 are provided, and the two second supports 42 are arranged at intervals along the circumference of the tightening ring 1; the first connecting assembly 4 also includes a clamping plate 44, and the clamping plate 44 is movably connected between the two second supports 42, and the clamping groove 441 is opened on the clamping plate 44; the inclination adjusting member 43 also includes two first nuts 432, and the two first nuts 432 are sleeved on the adjusting screw 431, and respectively abut against the two sides of the clamping plate 44.

[0060] In the embodiment of the present application, on the one hand, since two second supports 42 and a clamping plate 44 with a clamping slot 441 are provided, the clamping plate 44 is movably connected between the two second supports 42, that is, the clamping plate 44 can rotate relative to the second supports 42. In this way, for the obliquely driven pipe piles 10 with different inclinations, the inclinations of the adjusting screw 431 are also different. Therefore, the clamping plate 44 can be properly rotated to better connect the clamping slot 441 with the adjusting screw 431, which is conducive to improving the connection reliability between the adjusting screw 431 and the clamping plate 44. On the other hand, since two first nuts 432 are provided, the two first nuts 432 are respectively abutted against the two sides of the clamping plate 44, that is, the adjusting screw 431 is locked from two directions, which is conducive to further improving the connection reliability between the adjusting screw 431 and the clamping plate 44, so that the clamping ring 1 and the guide assembly 2 are reliably connected.

[0061] like Figure 6 As shown, the second connecting component 5 includes a third support 51, a fourth support 52 and a fastener 53; the third support 51 is arranged on the side of the guide component 2 close to the tightening ring 1, the fourth support 52 is arranged on the side of the tightening ring 1 close to the guide component 2, and the fourth support 52 is connected to the third support 51 via the fastener 53.

[0062] In the embodiment of the present application, since the third support 51 and the fourth support 52 are provided, the third support 51 and the fourth support 52 are connected by the fastener 53, so that the clamping ring 1 and the guide assembly 2 can be reliably connected. It should be noted that in the process of assembling the new horizontal cutter for the end of the obliquely driven pipe pile, since it is necessary to adjust the inclination of the clamping ring 1 relative to the guide assembly 2 to adapt to different obliquely driven pipe piles 10, before the adjustment, the fastener 53 first connects the clamping ring 1 and the guide assembly 2 together. At this time, the fastener 53 is not tightened, and the clamping ring 1 can still rotate relative to the guide assembly 2; after the adjustment, the fastener 53 is tightened, and the clamping ring 1 and the guide assembly 2 are relatively fixed, so that the clamping ring 1 and the guide assembly 2 are reliably connected together, and the first center line and the first axis maintain a corresponding angle.

[0063] In some optional embodiments of the present application, the clamp ring 1 includes two arc-shaped clamp members 11, and the two arc-shaped clamp members 11 are connected by a lock buckle 7. The guide assembly 2 includes two arc-shaped guide members 21, and one arc-shaped guide member 21 is correspondingly connected to one arc-shaped clamp member 11; wherein one end of the two arc-shaped guide members 21 is hinged, and the other end of the two arc-shaped guide members 21 is connected by a lock buckle 7.

[0064] In the embodiment of the present application, since the clamp ring 1 includes two arc-shaped clamp members 11, the guide assembly 2 includes two arc-shaped guide members 21, and one end of the two arc-shaped guide members 21 is hinged. In this way, in the process of cutting the end of the oblique-driven pipe pile 10 using the new oblique-driven pipe pile end horizontal cutter of the embodiment of the application, the arc-shaped clamp members 11 are connected to the arc-shaped guide members 21 in a one-to-one correspondence, and the two arc-shaped guide members 21 are hinged and installed on the circumference of the oblique-driven pipe pile 10, and the two arc-shaped fasteners 53 and the two arc-shaped guide members 21 are locked by the lock buckle 7, so that the clamp ring 1 and the guide assembly 2 can be reliably connected to the oblique-driven pipe pile 10 for subsequent cutting work.

[0065] It should be noted that, in the case where two arc-shaped tightening members 11 and two arc-shaped guide members 21 are provided, Figure 3 to Figure 4 As shown, two first connecting components 4 and two second connecting components 5 are also provided respectively.

[0066] In addition, the embodiment of the present application provides a specific structure of a lock buckle 7, such as Figure 6 As shown, taking the lock buckle 7 installed on the clamp ring 1 as an example, the lock buckle 7 of the embodiment of the present application includes a bolt 71, a clamping block 73 and a second nut 72. The bolt 71 is movably connected to one of the arc-shaped clamping members 11, and the clamping block 73 is arranged on the other arc-shaped clamping member 11. The clamping block 73 is provided with a groove. The bolt 71 is clamped in the groove by rotating the bolt 71, and the second nut 72 is used for locking, thereby realizing a reliable connection between the two arc-shaped clamp rings 1. It should be noted that on the basis of realizing the locking effect, those skilled in the art can also select lock buckles 7 of other structures according to actual needs, which is not limited here.

[0067] In some optional embodiments of the present application, the clamping ring 1 and the guide assembly 2 are both provided with a locking hole 8; the novel obliquely driven pipe pile end horizontal cutter also includes a locking bolt 9, and the locking bolt 9 is passed through the locking hole 8 and abuts against the obliquely driven pipe pile 10.

[0068] In actual applications, due to the existence of processing errors, there will inevitably be gaps in the contact parts of the clamping ring 1, the guide assembly 2 and the obliquely driven pipe pile 10. Based on this, the embodiment of the present application is provided with a locking hole 8 and a locking bolt 9. The locking bolt 9 is passed through the locking hole 8 and abuts against the obliquely driven pipe pile 10. This can improve the connection reliability of the clamping ring 1, the guide assembly 2 and the obliquely driven pipe pile 10, which is beneficial to the subsequent cutting work.

[0069] It should be noted that the embodiment of the present application does not limit the number and position of the locking holes 8, and those skilled in the art can adjust them according to actual needs. It is understandable that the number of locking bolts 9 and locking holes 8 is consistent, so that the locking bolts 9 and locking holes 8 are locked one by one. In one embodiment, Figure 2 As shown, both the clamping ring 1 and the guide assembly 2 are provided with a plurality of locking holes 8, wherein, for the clamping ring 1 with a circular cross-section, the plurality of locking holes 8 are arranged at intervals along the circumference of the clamping ring 1; and for the guide assembly 2 with an elliptical cross-section, the plurality of locking holes 8 are concentrated in the area where the distance between the guide assembly 2 and the obliquely driven pipe pile 10 is relatively small.

[0070] In practical applications, in order to improve the strength of the clamp ring 1, the clamp ring 1 of the embodiment of the present application is further provided with a reinforcing rib 12, which is provided on the side of the clamp ring 1 close to the guide assembly 2 and is extended along the circumference of the clamp ring 1. It should be noted that one or more reinforcing ribs 12 can be provided. When multiple reinforcing ribs 12 are provided, the multiple reinforcing ribs 12 are provided at intervals along the direction of the first axis on the side of the clamp ring 1 close to the guide assembly 2. It can be understood that when multiple reinforcing ribs 12 are provided, the structural strength of the clamp ring 1 can be further improved to prevent the clamp ring 1 from being deformed.

[0071] In addition, when the size of the obliquely driven pipe pile 10 is larger, the weight of the new obliquely driven pipe pile end horizontal cutter is also increased accordingly. In order to facilitate the installation of the new obliquely driven pipe pile end horizontal cutter on the obliquely driven pipe pile 10, the clamping ring 1 is also provided with a plurality of hooks 13, which are used to connect with external lifting equipment to assist the transfer and installation of the new obliquely driven pipe pile end horizontal cutter, which is conducive to improving the convenience of cutting work.

[0072] In some optional embodiments of the present application, the novel horizontal cutter for the end of an obliquely driven pipe pile also includes a slide rail frame 6, which is slidably connected to the slide rail 22; the cutting assembly 3 is movably connected to the side of the slide rail frame 6 away from the slide rail 22, and the slide rail frame 6 moves circumferentially along the slide rail 22 and drives the cutting assembly 3 to cut the obliquely driven pipe pile 10.

[0073] Specifically, the guide assembly 2 includes a body and a slide rail 22 which are sequentially arranged and connected to each other along the first center line direction, wherein the slide rail 22 includes a first guide plate and a second guide plate which are arranged perpendicular to each other.

[0076] In the embodiment of the present application, on the one hand, since a disc cutter 31 is provided, and the cutting direction of the disc cutter 31 is perpendicular to the first center line. In this way, when the driving member 33 drives the disc cutter 31 to rotate, cutting can be performed in a horizontal direction around the circumference of the obliquely driven pipe pile 10, so that the obliquely driven pipe pile 10 after cutting has a horizontal cutting surface, which can improve the cutting efficiency and the flatness of the end surface compared with the manual hammer chisel of the prior art. On the other hand, since a base plate 32 is provided to be movably connected to the slide rail frame 6, and a push-pull rod 34 is fixedly connected to the base plate 32, the staff can move the disc cutter 31 closer to or away from the obliquely driven pipe pile 10 by operating the push-pull rod 34.

The connecting columns 321 are penetrated through the connecting holes 63 one by one, so that the base plate 32 can swing in the horizontal direction relative to the slide rail frame 6, thereby driving the disc cutter 31 to approach or move away from the oblique pipe pile 10. In addition, the driving member 33 is an electric motor, and the disc cutter 31 and the electric motor are driven by a belt. It should be noted that those skilled in the art can also adopt other transmission methods, such as gear transmission, to realize the rotation of the disc cutter 31, which is not limited here.

[0082] 3. Install the slide rail frame 6 onto the track of the guide assembly 2;

[0083] 4. Install the cutting assembly 3 onto the slide rail frame 6;

[0084] 5. Start the driving member 33, and the staff pushes the push-pull rod 34 to make the cutting assembly 3 move around the track to cut the obliquely driven pipe pile 10, so that the obliquely driven pipe pile 10 has a horizontal cutting surface after cutting.

[0085] In summary, the novel horizontal cutter for the end of an obliquely driven pipe pile provided in the embodiment of the present application has at least the following advantages:
