[0027] See also Figures 1 to 6 As shown, the utility model is a highway section pipe jacking construction device, including a base 18 and a support platform, the support platform is located above the base 18, and a lifting and pushing device 21 is arranged between the support platform and the base 18, and the lifting and pushing device 21 can control the vertical movement of the support platform. During construction, the base 18 can be set at the bottom of the groove pit, and the support platform is moved upward by the lifting and pushing device 21 until its top surface is flush with the ground, and then the pipe body located on the ground is moved to be located on the support platform. The lifting and pushing device 21 can be used to control the support platform to move downward so that the pipe body is located in the groove pit. The lifting and pushing device 21 has a telescopic structure, which mainly controls the vertical movement of the support platform through the telescopic structure, and a hydraulic cylinder or other device can be used.

[0028] When the pipe 16 on the ground is moved to the support platform, it is necessary to control the pipe 16 to roll on the ground, so a retractable side frame 1 is connected to the base 18, and the side frame 1 is hinged to the base 18. A flat seat plate 28 is arranged above the side frame 1, and the flat seat plate 28 is placed on the ground and connected to the ground through anchor rods. An inner support rod can also be installed on the side frame 1, and this inner support rod is located in the groove pit, one end of the inner support rod is docked on the side frame 1, and the other end is against the inner wall of the groove pit. At this time, the position of the flat seat plate 28 can also be ensured to be stable, and a mechanical arm 12 is arranged on the flat seat plate 28. This mechanical arm 12 extends horizontally and crosses over the top of the groove pit. When the mechanical arm 12 is translated, the pipe 16 on the bottom surface can be moved to the groove pit. Specifically, a support arm 4 is arranged on the flat seat plate 28, and a horizontally extending limit sleeve 23 is fixed to the upper end of the support arm 4. The mechanical arm 12 passes through the limiting sleeve 23, and a base 2 is also provided on the flat seat plate 28. A horizontally extending push device 3 is fixed on the base 2. The push device 3 also has a telescopic structure. The free end of the push device 3 is connected to the mechanical arm 12. When the push device 3 is extended or retracted, the mechanical arm 12 can be controlled to move horizontally. The other end of the mechanical arm 12 is detachably connected to a mechanical claw. When the mechanical arm 12 moves toward the pipe 16, the mechanical claw is not connected to the mechanical arm 12. When the end of the mechanical arm 12 passes over the pipe 16, the mechanical claw is connected to the end of the mechanical arm 12, and at this time, the mechanical arm 12 and the mechanical claw form a vertical docking state. The mechanical claw is located on the outside of the pipe 16, and then the mechanical claw can be driven to move toward the groove pit by contraction of the push device 3. In this process, the mechanical claw applies a thrust to the pipe 16 to move toward the groove pit.

[0029] The connection structure between the mechanical arm 12 and the mechanical claw is as follows:

[0030] The mechanical claw is composed of a flat suspension rod 24 and a vertical claw rod 15. There are two vertical claw rods 15, which are respectively fixed at the two ends of the flat suspension rod 24, and the two vertical claw rods 15 are vertically fixed to the flat suspension rod 24. At the same time, a flat extension plate 13 is fixed at one end of the mechanical arm 12. Plug holes are provided on the flat extension plate 13 near the two ends, and a stabilizing sleeve 14 is fixed on the lower surface of the flat extension plate 13. The upper end of the stabilizing sleeve 14 is docked with the plug hole. When the mechanical claw is docked and assembled with the mechanical arm 12, the two vertical claw rods 15 on the mechanical claw are simultaneously inserted into the two plug holes on the flat extension plate 13, and finally the lower end of the vertical claw rod 15 is extended from the lower end of the stabilizing sleeve 14, and the docking of the two is completed at this time.

[0031] In addition, there is a distance between the robot arm 12 and the ground. In order to ensure the stability of the robot arm 12, a plurality of support arms 17 are arranged on the robot arm 12. Each support arm 17 is arranged vertically and a caster is connected to the lower end of the support arm 17. When the robot arm 12 crosses over the top of the groove, the push device 3 is located on one side of the groove, and the support arm 17 is located on the other side of the groove. Since there are a plurality of support arms 17 and the plurality of support arms 17 are arranged along the length direction of the robot arm 12, the support arms 17 play a certain supporting role on the robot arm 12, so when the robot arm 12 is translated, it has a certain stability.

[0032] In order to facilitate the adjustment of the pipeline 16 in the groove, the above-mentioned support platform is set to a double-layer structure, that is, the support platform includes a bottom platen 9 and an upper platen 8, the center positions of the two are connected by a central axis 25, the upper platen 8 can rotate, and a plurality of spherical pits are arranged on the bottom platen 9, each spherical pit is equipped with a ball 26, when the upper platen 8 is located above the bottom platen 9, a plurality of ball bearings 26 support the upper platen 8 and facilitate the rotation of the upper platen 8.

[0033] After the pipe 16 is moved to the support platform and located in the groove pit, it may be necessary to dock the pipe 16 with other pipes 16. At this time, the pipe 16 on the support platform needs to be translated, that is, the pipe 16 on the support platform needs to slide along the axial direction, so two flat support adjustment components can be set on the upper platform 8. The two flat support adjustment components are on the same straight line track, and this straight line track passes through the center of the upper platform 8. One of the flat support adjustment components is connected to a horizontal inner push component;

[0034] The above-mentioned flat support adjustment assembly includes a horizontally arranged flat support plate 7, two vertical guide plates 6 are fixed on the upper surface of the flat support plate 7, a support block 5 is arranged between the two vertical guide plates 6, the inner side surface of each vertical guide plate 6 is provided with a vertically extending guide groove, a slider located in the guide groove is fixed on the support block 5, the top surface of the support block 5 is an arched surface, and a horizontal through groove is arranged in the middle position of the top surface of the support block 5. When the pipeline 16 falls on the support block 5, a part of the pipeline 16 is located in the horizontal through groove, and a vertical through groove is arranged on the flat support plate 7. A threaded hole is passed through, and an adjusting screw 11 is screwed into the threaded hole. The adjusting screw 11 is located directly below the support block 5. When the adjusting screw 11 is screwed clockwise, the adjusting screw 11 will move upward. At this time, the adjusting screw 11 will push the support block 5 to move upward. Conversely, when the adjusting screw 11 is screwed counterclockwise, the adjusting screw 11 will move downward. At this time, the horizontal height of the support block 5 is reduced, and the horizontal height of the pipeline 16 can be adjusted, and the pipeline 16 can also be adjusted to form a horizontal state, which is convenient for the docking construction of the pipeline 16.

[0035] After the pipeline 16 is adjusted to a horizontal state, the pipeline 16 is pushed horizontally by a horizontal inner push assembly. Specifically, the horizontal inner push assembly includes a guide rod 10 arranged on the support block 5. A horizontal through-hole is arranged on the support block 5. The guide rod 10 passes through the hole on the support block 5 so that the guide rod 10 can slide along the length direction of the horizontal through-hole. The hole is located below the horizontal through-hole, and the two are connected by a long straight notch. A push rod 29 is vertically fixed to the outer end of the guide rod 10. When the guide rod 10 slides horizontally, the push rod 29 applies a thrust to the end of the pipeline 16.

[0036] When controlling the horizontal movement of the guide rod 10, a protruding tooth is provided on the lower surface of the guide rod 10, and a transmission notch is provided on the lower surface of the support block 5. The transmission notch is connected to the horizontally penetrating channel, and a rotatable transmission gear 27 is provided in the transmission notch. The transmission gear 27 is connected to a driving motor, and the driving motor is installed on the lower surface of the support block 5. When the output shaft of the driving motor rotates, the guide rod 10 can be controlled to move horizontally, thereby driving the push rod 29 to move, and finally realizing the pushing of the pipeline 16.

[0037] In addition, in order to maintain the stability of the support platform, a basic column 19 is fixed at the center position of the base 18. The basic column 19 is a cylinder. The lifting device 21 is fixed to the upper end of the basic column 19. A longitudinal sliding sleeve 20 is sleeved on the basic column 19. An arc arm 22 is fixed on the longitudinal sliding sleeve 20. The upper end of the arc arm 22 is docked on the upper platform 8, forming a relatively stable support structure.

[0038] When in use, the device can be used to connect the pipe 16 in the surface groove of the highway. At this time, the groove is directly excavated on the ground, so the groove has an upper opening, and the device can be directly placed in the groove; it can also be used to connect the pipe 16 in the excavation channel below the surface. At this time, the excavation channel where the pipe 16 is located does not have an opening. During construction, it is necessary to connect the pipe 16 in the inspection well. In this construction situation, it is necessary to first excavate a pit with a certain depth on the ground, and then use this pit as the starting section to carry out horizontal hole excavation, and finally form an excavation channel located below the surface. The two ends of this excavation channel are in an open state, and then the device can be placed in the pit. After moving the surface pipe 16 to the flat support adjustment component on the device, the upper platform 8 is rotated to align the pipe 16 with the excavation channel, and then the horizontal inner push component is used to horizontally push the pipe 16 to allow the pipe 16 to enter the excavation channel.
