[0025] 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.

[0026] Referring to the attached Figures 1-3 As shown, a pipe laying grooving machine for highway reconstruction and expansion in this embodiment includes a vehicle body 1. A fixed frame 5 is provided outside the vehicle body 1. An elevating assembly that elevates along the fixed frame 5 is provided inside the fixed frame 5. The elevating assembly is linked with a transmission assembly through a connecting rod assembly. A cutting roller 14 is rotatably connected to the side of the transmission assembly. When the connecting rod assembly moves, it links the transmission assembly to flip along the elevating assembly within a set path to form a grooving range with a set width; at this time, the movement range of the connecting rod assembly can be controlled to drive the determination of the flipping range of the transmission assembly, and at this time, the control of the width of the entire groove body can be completed to solve the problem that the width cannot be adjusted in the background art.

[0027] It further includes a second motor 11 fixed outside the connecting rod assembly. The second motor 11 drives the transmission assembly to perform grooving operations through the cutting roller 14 when the elevating assembly rises to a set height. At this time, the purpose of the second motor 11 is to start the entire grooving operation. Compared with simple grooving, in this embodiment, the connecting rod drives the transmission assembly to flip along the set position, and the width is adjusted during the flipping while the grooving operation is completed.

[0028] In this embodiment, specifically, the elevating assembly includes a first motor 6 located at the top of the fixed frame 5 and a threaded rotating rod 7 connected to the output end of the first motor 6. A slide block 8 is sleeved outside the threaded rotating rod 7. At this time, through the action of the first motor 6, the threaded rotating rod 7 and the slide block outside the threaded rotating rod 7 can perform corresponding lifting and lowering within the fixed frame 5, and at this time, the fixed frame 5 has a certain protective effect.

[0029] In order to achieve better assembly, in this embodiment, one end of the threaded rotating rod 7 vertically penetrates through the fixed frame and is rotatably connected to the inner bottom of the fixed frame 5 through a bearing seat. A through hole for the threaded rotating rod 7 to penetrate and rotate is provided on the fixed frame 5. Thus, the threaded rotating rod 7 can rotate through the through hole.

[0030] For the slidable block 8 that can move up and down, a threaded through hole for threaded connection with the threaded rotating rod 7 is provided thereon. The outer side of the slidable block 8 is in contact with the inner wall of the fixed frame 5 (the threaded rotating rod 7 is lubricated irregularly). The slidable block 8 is connected to the threaded rotating rod 7. At this time, when the first motor 6 that can rotate forward and backward reversely acts, it will drive the threaded rotating rod 7 to rotate synchronously. At this time, the slidable block 8 will rotate with the self-rotation of the threaded rotating rod 7, and then move up and down in the fixed frame 5 to complete the lifting.

[0031] Specifically, the connecting rod assembly includes an electric push rod 9 hinged to the outer side of the slidable block 8. The push rod end of the electric push rod 9 is hinged to a fixed frame 10 through a hinge seat. The second motor 11 is fixed to the side of the fixed frame 10, and the side of the fixed frame 10 is linked to the cutting roller 14 through a connecting rod 17. In this embodiment, it can be seen that the fixed frame 10 is arranged in a similar L-shaped structure. A connecting rod is arranged in its vertical direction, specifically connected to the second toothed belt pulley 15. The purpose is that the connection between the connecting rod 17 and the second toothed belt pulley 15 provides a mechanical connection for lifting operations, facilitating raising or lowering the rotating cutting roller 14, thereby facilitating the control of the cutting depth. In actual use, in order to protect the motor from interference, etc., a protective cover 13 is provided outside the second motor 11. The protective cover 13 is partially fixed to the fixed frame 10. At this time, it is specifically fixed in the vertical direction to ensure safety.

[0032] Referring to the accompanying drawings, it can be seen that in this embodiment, the transmission assembly includes a first toothed belt pulley 12 and a second toothed belt pulley 15 connected by a toothed chain, and the cutting roller 14 is provided concentrically on the outer periphery of the second toothed belt pulley 15. Through this transmission method, the stability is high and it is safer to use.

[0033] In this embodiment, the first toothed belt pulley 12 with a diameter smaller than that of the second toothed belt pulley 15 is fixedly connected to the output shaft of the second motor 11. The cutting roller 14 is located on the outer periphery of the second toothed belt pulley 15, and the two are concentrically arranged. In this embodiment, the cutting roller 14 is attached with a toothed chain composed of a grooved connecting belt. The belt is rotated by the power provided by the second motor 11. The second toothed belt pulley 15 is tightly connected to the cutting roller 14 and rotates synchronously with it. The radius of the second toothed belt pulley 15 is larger than that of the cutting roller 14, and the rotational speed is greater and the power is stronger after rotation.
