Description

Technical Field

[0001] This application relates to the field of high-pressure jet grouting construction, and more specifically, to a track-type jet grouting equipment with a tracked walking device. Background Technology

[0002] Currently, after the completion of tunnel construction (such as subway tunnels), it is often necessary to reinforce certain sections of the tunnel to improve its structural stability. Existing TGS equipment, as disclosed in publication number CN111550182A, includes a multi-angle cement-soil pile construction device and a tunnel reinforcement construction method. The multi-angle cement-soil pile construction device includes a high-pressure jet grouting machine. The high-pressure jet grouting machine comprises a vehicle body, a traveling mechanism, a working platform, a drill rod device, a rotating tower mechanism, and a power head. The rotating tower mechanism includes a rotating seat rotatably mounted on the working platform via a horizontal axis, a rotating seat rotation actuator for driving the rotating seat, a supporting tower rotatably mounted on the rotating seat, a tower rotation actuator mounted on the rotating seat for driving the supporting tower, a guide rail mounted on the supporting tower, and a sliding seat sliding along the guide rail. The power head is mounted on the sliding seat for driving the jet grouting drill rod to rotate. While this equipment effectively simplifies tunnel reinforcement construction steps, improves construction efficiency, and provides good tunnel reinforcement results, it is not without its limitations. However, this jet grouting machine is a tracked type, and its positioning accuracy is poor after entering the tunnel. The tracked jet grouting machine cannot accurately move the jet grouting machine to the corresponding drilling and spraying position.

[0049] The track-walking mechanism includes: ground rail 11, crossbar 13, slide rail 12, and travel cylinder 14.

[0050] Two symmetrically positioned ground rails 11 are fixedly connected to the bottom of the tunnel. Two symmetrically positioned sliding rails 12 are slidably installed on the ground rails 11 on both sides. Two crossbars 13 are provided, with their ends fixedly connected to the sliding rails 12 on both sides respectively. The operating platform 15 is fixedly connected to the two crossbars 13. The housing of the traveling cylinder 14 is hinged to the top wall of the sliding rail 12, and the cylinder rod of the traveling cylinder 14 is installed on one end of the ground rail 11.

[0051] The top wall of the mounting base 18 is provided with multiple arc-shaped grooves 20 and adjustment grooves 22. The tracked walking mechanism 19 is installed on both side walls of the mounting base 18. The adjustment plate 23 is rotatably connected to the adjustment groove 22. The lifting cylinder 24 is fixedly connected to the bottom wall of the operating platform 15. The adjustment plate 23 is fixedly connected to the cylinder push rod of the lifting cylinder 24. The mounting base 18 is rotatably connected to the adjustment plate 23. One end of the adjustment cylinder 17 is hinged to the operating platform 15. A part of the high-pressure jet grouting machine 16 is hinged to the operating platform 15. The cylinder rod of the adjustment cylinder 17 is hinged to a part of the high-pressure jet grouting machine 16. Multiple telescopic rods 21 are provided. One end of the telescopic rod 21 is fixedly connected to the bottom wall of the operating platform 15. The other end of the telescopic rod 21 is slidably connected to the arc-shaped groove 20. The end of the telescopic rod 21 that extends into the arc-shaped groove 20 is provided with a spherical arc surface. The end wall of the telescopic rod 21 that extends into the arc-shaped groove 20 is in sliding contact with the side wall of the arc-shaped groove 20.

[0052] In order to drive the adjusting plate 23 to rotate around its own axis, a driving component is also provided, which includes: a gear ring 25, a drive motor 26, and a gear 27.

[0053] The gear ring 25 is sleeved and fixedly connected to the side wall of the adjusting plate 23, the drive motor 26 is fixedly connected to the mounting base 18, and the gear 27 is fixedly connected to the output shaft of the drive motor 26. The gear ring 25 meshes with the gear 27.

[0054] The specific structure of the high-pressure jet grouting pile machine 16 can be found in the high-pressure jet grouting pile machine disclosed in publication number CN111550182A. The high-pressure jet grouting pile machine includes a vehicle body, a traveling mechanism, a working platform, a drill rod device, a rotating tower mechanism, and a power head.

[0055] Work or installation process:

[0056] Before entering the tunnel, the lifting cylinder 24 is activated, the cylinder rod of the lifting cylinder 24 extends and drives the adjusting plate 23 to move downward, the adjusting plate 23 drives the mounting base 18 to move downward, and the adjusting plate 23 drives the mounting base 18 to move downward, causing multiple telescopic rods 21 to extend. The mounting base 18 drives the track walking mechanism 19 to move downward until the track walking mechanism 19 contacts the ground, and at this time the slide rail 12 is suspended on the ground. The track walking mechanism 19 is activated and drives the entire equipment to walk on the ground and move into the tunnel.

[0057] When the tracked walking mechanism 19 moves the entire equipment into the tunnel, it moves the slide rails 12 on both sides directly above the ground rails 11. At this time, the drive motor 26 starts, and the output shaft of the drive motor 26 drives the gear 27 to rotate. The gear 27 meshes with the gear ring 25, which in turn drives the gear ring 25 to rotate. The gear ring 25 drives the adjusting plate 23 to rotate, which in turn drives the lifting cylinder 24 to rotate. The lifting cylinder 24 drives the operating platform 15 to rotate, and the operating platform 15 drives the slide rails on both sides via the crossbar 13. 12 rotates around the circumference of the gear ring 25, so that the slide rails 12 on both sides are aligned with the ground rails 11 laid at the bottom of the tunnel. Then, the lifting cylinder 24 depressurizes and retracts, and the lifting cylinder 24 drives the adjusting plate 23 to move upward. The adjusting plate 23 drives the mounting base 18 to move upward. The mounting base 18 drives the track walking mechanism 19 to move upward until the track walking mechanism 19 is out of contact with the ground. At this time, the slide rail 12 is mounted on the ground rail 11. Then, one end of the cylinder rod of the walking cylinder 14 is hinged to the ground rail 11 by bolts and nuts.

[0058] When the travel cylinders 14 on both sides are hinged to the ground rails 11 on both sides, the travel cylinders 14 are activated, the travel cylinders 14 extend and push the slide rails 12 to move along the extension direction of the ground rails 11, so that the whole equipment moves on the ground rails 11.
