Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-5 As shown, a pipe jacking device for a water-rich sand layer includes a top plate 1. Two hydraulic cylinders 2 are fixedly connected to the outside of the top plate 1. Push rings 3 are fixedly connected to the output ends of the two hydraulic cylinders 2. A slide rail 4 is fixedly connected to the outside of the top plate 1. Multiple first balls 5 are slidably connected inside the slide rail 4. A limit mechanism 6 is provided at the top of the slide rail 4. A warning mechanism 7 is provided on the outside of the top plate 1.

[0027] The limiting mechanism 6 includes a mounting frame 60, the bottom of which is fixedly connected to the top of the slide rail 4. A first motor base 61 is fixedly connected to the outside of the mounting frame 60, and a first motor 62 is fixedly connected to the outside of the first motor base 61. A rotating shaft 63 is fixedly connected to the output end of the first motor 62. A first synchronous pulley 64 is fixedly connected to both ends of the rotating shaft 63. Two threaded rods 65 are rotatably connected inside the mounting frame 60. A second synchronous pulley 66 is fixedly connected to one end of each of the two threaded rods 65. A synchronous belt 67 is sleeved between the first synchronous pulley 64 and the second synchronous pulley 66. A threaded sleeve 68 is threadedly connected to the outer circumference of the threaded rods 65. Two sliders 69 are fixedly connected to the outer circumference of the threaded sleeve 68. An arc-shaped limiting block 610 is fixedly connected to the outside of the threaded sleeve 68. Multiple second balls 611 are rotatably connected inside the arc-shaped limiting block 610. Two fixing blocks 612 are fixedly connected to the outer sides of both ends of the mounting frame 60.

[0028] It should be noted that when the limiting mechanism 6 needs to be adjusted, the first motor 62 is started, the first motor 62 drives the rotating shaft 63 to rotate, and then drives the two threaded rods 65 to rotate synchronously through the first synchronous pulley 64, the synchronous belt 67 and the second synchronous pulley 66, so that the threaded sleeve 68 moves along the threaded rod 65, and adjusts the position of the arc-shaped limiting block 610 to adapt to the jacking pipe of different sizes.

[0029] The warning mechanism 7 includes an infrared sensor 70 and a mounting plate 71. The infrared sensor 70 is fixedly connected to the outside of the slide rail 4. The mounting plate 71 is fixedly connected to the outside of the top plate 1. A second motor base 72 is fixedly connected to the outside of the mounting plate 71. A second motor 73 is fixedly connected to the outside of the second motor base 72. A drive block 74 is fixedly connected to the output end of the second motor 73. An eccentric shaft 75 is fixedly connected to the outer edge of the drive block 74. A swing frame 76 is slidably connected to the outer periphery of the eccentric shaft 75. A toothed block 77 is fixedly connected to the bottom of the swing frame 76. Two connecting blocks 78 are fixedly connected to the outside of the mounting plate 71. A support rod 79 is fixedly connected between the two connecting blocks 78. A rack 710 is slidably connected to the outside of the support rod 79. A mounting block 711 is fixedly connected to the bottom of the rack 710. A first electrode plate 712 is fixedly connected to the outside of the mounting block 711. A flashing light 713 is fixedly connected to the outside of the mounting plate 71. A second electrode plate 714 is fixedly connected to the outside of the flashing light 713. A controller 715 is fixedly connected to the outside of the mounting plate 71.

[0030] It should be noted that when the infrared sensor 70 detects an abnormal jacking speed, the controller 715 starts the second motor 73. The second motor 73 drives the swing frame 76 to swing by driving the block 74 and the eccentric shaft 75. Then, through the meshing of the toothed block 77 and the rack 710, the rack 710 moves, driving the mounting block 711 and the first electrode plate 712 to move. When the first electrode plate 712 contacts the second electrode plate 714, the flashing light 713 is triggered as an alarm.

[0031] like Figure 2 , Figure 3 As shown, the outer side of the slider 69 is slidably connected to the inside of the fixed block 612.

[0032] It should be noted that the outer side of the slider 69 is slidably connected to the inside of the fixed block 612 to ensure the stability of the movement of the threaded sleeve 68.

[0033] like Figure 2 , Figure 3 As shown, the outer circumference of the rotating shaft 63 is rotatably connected to the inside of the mounting bracket 60.

[0034] It should be noted that the outer circumference of the rotating shaft 63 is rotatably connected inside the mounting bracket 60 to ensure the smooth rotation of the rotating shaft 63.

[0035] like Figure 1 , Figure 4 , Figure 5 As shown, the outer side of the swing frame 76 is rotatably connected to the outer side of the mounting plate 71.

[0036] It should be noted that the outer side of the swing frame 76 is rotatably connected to the outer side of the mounting plate 71, so that the swing frame 76 can swing flexibly.

[0037] like Figure 1 , Figure 4 , Figure 5 As shown, the outer side of the drive block 74 is rotatably connected to the inside of the second motor base 72.

[0038] It should be noted that the outer side of the drive block 74 is rotatably connected inside the second motor base 72 to ensure the stability of the drive block 74's rotation.

[0039] like Figure 1 , Figure 4 , Figure 5 As shown, the toothed block 77 and the rack 710 mesh with each other.

[0040] It should be noted that the meshing between the toothed block 77 and the rack 710 enables the power transmission between the swing frame 76 and the rack 710.

[0041] like Figure 1 , Figure 4 , Figure 5 As shown, the rack 710 is slidably connected to the outside of the mounting plate 71.

[0042] It should be noted that the outer side of the rack 710 is slidably connected to the outer side of the mounting plate 71 to ensure the stability of the rack 710's movement.

[0043] The working principle of this utility model is as follows: During the jacking process, the hydraulic cylinder 2 pushes the jacking pipe forward through the push ring 3. By starting the first motor 62, the first motor 62 drives the rotating shaft 63 to rotate, which in turn drives the two threaded rods 65 to rotate synchronously through the first synchronous pulley 64, the synchronous belt 67, and the second synchronous pulley 66. This causes the threaded sleeve 68 to move along the threaded rod 65, adjusting the position of the arc-shaped limit block 610 to accommodate jacking pipes of different sizes. When the infrared sensor 70 detects an abnormal jacking speed, the controller 715 starts the second motor 73. The second motor 73 drives the swing frame 76 to swing through the drive block 74 and the eccentric shaft 75. This causes the rack 710 to move through the meshing of the toothed block 77 and the rack 710, which in turn moves the mounting block 711 and the first electrode plate 712. When the first electrode plate 712 contacts the second electrode plate 714, the flashing light 713 is triggered as an alarm.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
