During the construction of the pipe jacking project, the sheet, annular or curved sheet materials used for the connecting parts between the pipe jacking can be grooved by the grooving mechanism 300, so as to form a groove body of preset shape and size on its surface to match the connection of the pipe jacking; in this process, the top side surface of the frame 100 is used as the horizontal reference plane, and the limiting mechanism 200 positions the component to be grooved, and limits the relative position between the component and the grooving mechanism 300 in the vertical direction, so as to ensure the accuracy of the groove body extending along the circumferential direction during the grooving process of the sheet material component, while simplifying the groove body processing process and improving the processing efficiency, ensuring the connection effectiveness between the connecting component and the pipe jacking, and improving the structural strength and sealing performance. Specifically, the grooving mechanism 300 includes a first grooving component 310 and a second grooving component 320, and the first grooving component 310 and the second grooving component 320 are both installed between the frame 100 and the limiting mechanism 200, wherein the first grooving component 310 cooperates with the limiting mechanism 200 to be arranged on the bottom side of the movable end of the limiting mechanism 200; the second grooving component 320 is arranged on one side of the first grooving component 310, and the second grooving component 320 corresponds to the first grooving component 310 at one end facing the first grooving component 310; thus, when the component is grooved by the grooving machine 10 for pipe jacking engineering of the present invention, the component is placed between the first grooving component 310 and the second grooving component 320, the movable end of the limiting mechanism 200 cooperates with the first grooving component 310 to clamp the component, and one end of the second grooving component 320 cooperates with the first grooving component 310 to grooving the surface of the component. Compared with traditional grooving equipment, the grooving machine 10 for pipe jacking engineering of the present invention can groove sheet, ring or curved sheet materials more quickly and effectively. While simplifying the groove body processing process and improving processing efficiency, it ensures the connection effectiveness between the connecting components and the pipe jacking, improves the structural strength and sealing performance, and thus meets the on-site grooving processing needs of pipe jacking construction.

[0031] Furthermore, the first grooving assembly 310 includes a first grooving roller 311, a first mounting seat 312, and a first driving unit 313.

A grooving protrusion a is disposed on the side surface of the first grooving roller 311 and engages with the second grooving assembly 320. When the component to be grooved is undergoing grooving processing, the component is arranged between the first grooving roller 311 and the second grooving assembly 320. At this time, the movable end of the limiting mechanism 200 cooperates with the end of the first grooving roller 311 to clamp the component; then, the first driving unit 313 drives the first grooving roller 311 to rotate through the first mounting seat 312, and the grooving protrusion a on the side surface of the first grooving roller 311 cooperates with the second grooving assembly 320 to perform grooving processing on the surface of the component.

[0032] Furthermore, the second grooving assembly 320 includes a second grooving roller 321, a second mounting seat 322, and a second drive unit 323.

Specifically, a mating groove b is provided on the side surface of the second grooving roller 321, which mates with the grooving protrusion a. When the component to be grooved is undergoing grooving processing, the component is set between the first grooving roller 311 and the second grooving roller 321; after the component is positioned, the second driving unit 323 drives the second grooving roller 321 to move toward the first grooving roller 311 through the second mounting seat 322, so that the grooving protrusions a on both sides of the component and the matching grooves b cooperate with each other to roll the side surface of the component, so that the side surface of the component forms a groove body of a preset shape and size.

[0033] In one embodiment, the first drive unit 313 is configured as a three-phase asynchronous motor, and the three-phase asynchronous motor is driven to connect to the bottom of the first mounting seat 312 through a transmission belt structure (not shown), thereby realizing the driving function of the first drive unit 313 on the first mounting seat 312.

[0034] In one embodiment, the second driving unit 323 is configured as a linear guide rail, and one end of the linear guide rail extends to one side of the first grooving roller 311, so that the second driving unit 323 can drive the second grooving roller 321 to perform linear reciprocating motion relative to the first grooving roller 311 through the second mounting plate.

[0035] Furthermore, the limiting mechanism 200 includes a nip roller 210, a mounting bracket 220, and a third drive unit 230. The mounting bracket 220 is disposed on the top surface of the frame 100. The third drive unit 230 is mounted on the top of the mounting bracket 220, and the output end of the third drive unit 230 is disposed toward the first groove pressing assembly 310.

Specifically, the bottom of the nip roller 210 corresponds to the top of the first groove pressing roller 311, and the nip roller 210 is rotatably mounted on the output end of the third drive unit 230. When the component to be grooved is subjected to tooth groove processing, the top of the component is set between the pressing roller 210 and the first grooving roller 311, and the third driving unit 230 drives the pressing roller 210 to descend, prompting the pressing roller 210 to cooperate with the first grooving roller 311 to clamp the component; when the first grooving roller 311 rotates, it can sequentially drive the pressing roller 210 and the component clamped by the two to rotate, and then cooperate with the second grooving roller 321 to complete the grooving processing.

[0036] In one embodiment, the third driving unit 230 is configured as a cylinder, and the output end of the cylinder is disposed toward the first grooving roller 311 , so that the third driving unit 230 can drive the nip roller 210 to perform reciprocating lifting motion relative to the first grooving roller 311 .

[0037] In one embodiment, the nip roller 210 is made of polyurethane material, thereby reducing the surface hardness of the nip roller 210 , thereby preventing the nip roller 210 from causing compression damage to the component when the nip roller 210 cooperates with the first grooving roller 311 to clamp the component to be grooved.

[0038] Furthermore, the first mounting seat 312 is provided with a clamping structure c, which is arranged at the top of the first mounting seat 312, and the clamping structure c corresponds to the bottom of the first grooving roller 311, so that the first grooving roller 311 can be mounted to the first mounting seat 312 in a detachable manner, thereby enabling the grooving machine 10 for pipe jacking engineering of the present invention to quickly replace the first grooving roller 311 according to specific processing requirements, thereby improving practical convenience and versatility.

[0039] In summary, the grooving machine for pipe jacking engineering disclosed by the present invention grooves the connecting parts of the pipe jacking through a grooving mechanism, thereby forming a groove body of a preset shape and size on its surface to match the connecting pipe jacking; in this process, the top side surface of the frame is used as the horizontal reference plane, and the limiting mechanism positions the component to be grooved, and limits the relative position between the component and the grooving mechanism in the vertical direction, thereby ensuring the accuracy of the groove body extending along the circumferential direction during the grooving process of the sheet component, while simplifying the groove body processing process and improving the processing efficiency, ensuring the connection effectiveness between the connecting component and the pipe jacking, and improving the structural strength and sealing performance. When the component is grooved by the grooving machine for pipe jacking engineering disclosed by the present invention, the component is placed between the first grooving assembly and the second grooving assembly, the movable end of the limiting mechanism cooperates with the first grooving assembly to clamp the component, and one end of the second grooving assembly cooperates with the first grooving assembly to groove the surface of the component.
