Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] Example 1, reference Figure 1-5 , a pipeline underground excavation construction device for a municipal environmental protection project, comprising a base 1, a shock-absorbing seat 2, a top seat 3 and a pipeline underground excavation construction mechanism; Furthermore, an arc-shaped notch 4 is provided on the top of the top seat 3, and a slidable pipe 5 is placed on the arc-shaped notch 4. The pipeline dark excavation construction mechanism includes a top pipe assembly, a splash cover 6 fixed to the side wall of the pipe 5 by bolts, a drive motor 7 fixed to the side wall of the splash cover 6 by bolts and located in the pipe 5, a transmission shaft 8 and an auger soil cutter 9 welded to the outer wall of the transmission shaft 8.

[0020] Furthermore, the output shaft of the driving motor 7 passes through the splash cover 6 and is coaxially fixedly connected to one end of the transmission shaft 8 through a coupling, and the outer walls of the two threaded sliders 12 are slidably connected to the inner walls of the two slide grooves 10 respectively; Furthermore, the synchronous manipulator includes two synchronous wheels 14 which are fixedly mounted on the two lead screws 11 in sequence, a motor bracket 15 which is welded to the side wall of the top seat 3, and a servo motor 16 which is fixed to the side wall of the motor bracket 15 by bolts; Furthermore, the output shaft of the servo motor 16 passes through the motor bracket 15 and is coaxially fixedly connected to one end of one of the lead screws 11 through a coupling, and the two synchronous wheels 14 are connected through the same synchronous belt 17; In the specific implementation of this embodiment: the spiral drill cutter 9 on the transmission shaft 8 is controlled to rotate by the driving motor 7, and then a coaxial lead screw 11 is controlled to rotate by the output shaft of the servo motor 16, and then the synchronous wheel 14 on the lead screw 11 rotates, and under the synchronous transmission of the synchronous belt 17, the other lead screw 11 rotates synchronously, so that the synchronous rotation of the two lead screws 11 controls the synchronous sliding of the two threaded sliders 12, and then the jacking metal part 13 can control the pipeline 5 and the high-speed rotating spiral drill cutter 9 to continue to move forward, so that excavation and jacking can be carried out simultaneously, which effectively improves the construction efficiency. In addition, since the machine integrates excavation and jacking, it can effectively reduce the area occupied by the equipment, which is convenient for use in a narrow underground environment. At the same time, it also reduces the cost of equipment use, thereby being able to meet the use requirements of municipal environmental protection projects.
[0021] Example 2, reference Figure 4 and Figure 6 , This embodiment is optimized on the basis of embodiment 1, specifically: a municipal environmental protection engineering pipeline dark excavation construction device, also includes a height adjustment mechanism; Furthermore, the height adjustment mechanism includes a guide rail 18 welded to the top outer wall of the shock-absorbing seat 2, a two-way cylinder 19 fixedly mounted on the top outer wall of the guide rail 18, two guide blocks 20 fixedly connected to the two piston rods of the two-way cylinder 19, and two linkage oblique rods 21 hinged to the tops of the two guide blocks 20 in turn; Furthermore, the two guide blocks 20 are slidably connected to the guide rail 18, the top ends of the two linkage oblique rods 21 are hinged to the bottom of the top seat 3, and the two linkage oblique rods 21 are arranged to be crossed and not in contact; In the specific implementation of this embodiment, the two piston rods of the two-way cylinder 19 control the two guide blocks 20 to move closer to or away from each other on the guide rail 18, and then under the linkage of the two linkage inclined rods 21, the top seat 3 can be lifted and lowered in the vertical direction, so that the construction height of the pipeline excavation construction mechanism can be flexibly adjusted, which can better meet the diverse construction needs of the construction site.
[0022] Example 3, reference Figure 1 and Figure 7 , this embodiment is optimized on the basis of embodiment 1, specifically: a municipal environmental protection engineering pipeline dark excavation construction device, further comprising a shock absorbing mechanism, the shock absorbing mechanism comprising a plurality of shock absorbing components equidistantly distributed between a base 1 and a shock absorbing seat 2; Furthermore, the shock absorbing assembly includes a connecting plate 22 fixedly connected to the bottom outer wall of the shock absorbing seat 2, a connecting frame 23 fixedly connected to the top outer wall of the base 1, two dampers 24 symmetrically installed between the connecting plate 22 and the connecting frame 23, two shock absorbing vertical springs 25 sleeved on the two dampers 24, a limiting slide column 26 welded on the connecting frame 23, two limiting sleeves 27 slidably connected to the limiting slide column 26, two hinged diagonal rods 28 symmetrically hinged to the top ends of the two limiting sleeves 27, and a shock absorbing transverse spring 29 sleeved on the limiting slide column 26.

At this time, the two shock absorbing vertical springs 25 on the two dampers 24 will undergo elastic deformation. At the same time, under the linkage of the two hinged inclined rods 28, the two limiting sliding sleeves 27 will slide on the limiting sliding column 26, thereby causing the shock absorbing transverse spring 29 to undergo elastic deformation. This can effectively reduce the vibration during the operation of the entire device, improve the stability of the operation of the entire device, and at the same time reduce the damage to the supporting ground caused by the vibration, thereby ensuring the stability of the support of the entire device.
[0024] The working method of the present invention is as follows: first, the two piston rods of the bidirectional cylinder 19 control the two guide blocks 20 to move closer to or away from each other on the guide rail 18, and then the top seat 3 can be lifted and lowered in the vertical direction under the linkage of the two linkage inclined rods 21, so that the construction height of the pipeline dark excavation construction mechanism can be flexibly adjusted, and the diversified construction requirements of the construction site can be better met; Secondly, after the height adjustment is completed, the auger 9 on the transmission shaft 8 is controlled to rotate by the driving motor 7, and then the coaxial lead screw 11 is controlled to rotate by the output shaft of the servo motor 16, and then the synchronous wheel 14 on the lead screw 11 rotates, and under the synchronous transmission of the synchronous belt 17, the other lead screw 11 rotates synchronously, so that the synchronous rotation of the two lead screws 11 controls the synchronous sliding of the two threaded sliders 12, and then the jacking metal part 13 can control the pipeline 5 and the high-speed rotating auger 9 to continue to move forward, so that the excavation and jacking can be carried out synchronously, which effectively improves the construction efficiency; Finally, the vibration generated during the operation of the entire device will be transmitted to the connecting plate 22 through the shock-absorbing seat 2. At this time, the two shock-absorbing vertical springs 25 on the two dampers 24 will undergo elastic deformation. At the same time, under the linkage of the two hinged inclined rods 28, the two limiting sliding sleeves 27 will slide on the limiting sliding column 26, thereby causing the shock-absorbing transverse spring 29 to undergo elastic deformation. This can effectively reduce the vibration during the operation of the entire device, improve the stability of the operation of the entire device, and at the same time reduce the damage to the supporting ground caused by the vibration, thereby ensuring the stability of the support of the entire device.
