Description

Technical Field

[0001] The invention belongs to the technical field of pipe jacking construction, in particular to an angle adjustment device for pipe jacking construction. Background Art

[0002] Pipe jacking is a trenchless or minimally excavated underground pipeline construction technique that uses jacking equipment to push the pipe from the working pit to the receiving pit, eliminating the need for extensive surface excavation. Within the working pit, the jacking force generated by the jacking equipment overcomes the friction between the pipe and the surrounding soil, pushing the tool pipe or tunnel boring machine through the soil at the designed slope and into the earth, removing the excavated soil. After one section of pipe is pushed into the soil, the second section is lowered and pushed in. The principle is to use the thrust of the main jacking cylinder and the pipeline and relay rooms to push the tool pipe or tunnel boring machine from the working pit through the soil and into the receiving pit, where it is hoisted. The pipeline is buried immediately behind the tool pipe or tunnel boring machine, between the two pits.

[0003] During the pipe jacking construction process, the inclination angle of the pipe is adjusted to adapt to different geological conditions and construction requirements. Through reasonable angle adjustment, it can ensure that the pipe is accurately jacked according to the preset slope and direction, avoiding construction difficulties and subsequent problems caused by angle deviation. In addition, angle adjustment can also improve construction efficiency and reduce rework and correction work caused by angle problems. The prior art also proposes solutions for pipe angle adjustment. A Chinese patent with announcement number CN222458611U discloses a pipe jacking angle adjustment device for pipe jacking construction, which includes a horizontal rotation mechanism, an adjustment cylinder, a first hinge block, a first hinge sleeve, a telescopic assembly, a rotation adjustment mechanism, etc. When adjusting the angle of the pipe jacking, the horizontal angle of the pipe jacking can be adjusted by the horizontal rotation mechanism, and the longitudinal angle of the pipe jacking can be adjusted by the cooperation between the two adjustment cylinders and the first hinge block and the first hinge sleeve. The cooperation between the fixing ring, the telescopic assembly, the splint and the rotation adjustment mechanism can make the device suitable for pipe jacking of different diameters, which can effectively improve the convenience and practicality of the device during the construction process.

[0004] In the current prior art, the adjustment device is lifted by a lifting device and a hanging rod on a support plate to control the lifting and lowering of the adjustment device. The jacking pipe is then inserted into a fixed ring, and the angle of the jacking pipe is adjusted by the adjustment device. However, during use, the jacking pipe is hoisted as a whole by a lifting device before the angle of the jacking pipe is adjusted. As a result, the jacking pipe is suspended in mid-air during the angle adjustment process, causing it to shake. Impact from external objects and wind may cause the entire jacking pipe to shake significantly, resulting in poor stability of the adjustment device, low adjustment efficiency, and low accuracy.

[0005] To this end, the present invention provides an angle adjustment device for pipe jacking construction. Summary of the Invention

DETAILED DESCRIPTION

[0011] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0012] like Figures 1 to 9 As shown, an angle adjustment device for pipe jacking construction according to an embodiment of the present invention includes a base plate 2, a mounting platform 3 is provided above the base plate 2, an adjustment component is provided between the base plate 2 and the mounting platform 3, a pair of guide rail plates 4 are provided on the upper surface of the mounting platform 3, a pipe jacking machine body 1 is provided above the pair of guide rail plates 4, and an adaptation component is provided on the upper surface of each of the guide rail plates 4. The adjustment component includes a group of mounting columns 51 provided on both sides of the upper surface of the base plate 2, a connecting plate 5 is provided between the base plate 2 and the mounting platform 3, and one end of the mounting column 51 is fixedly connected to a No. 1 telescopic rod 52; One end of the No. 1 telescopic rod 52 is fixedly connected to the No. 1 fixing seat 53, and the No. 1 fixing seat 53 is rotatably connected to the side of the lower surface of the connecting plate 5 away from the mounting post 51. One side of the upper surface of the mounting post 51 is provided with a No. 1 slide groove 54, and the No. 1 slide groove 54 is slidably connected to the No. 1 support rod 55, and one end of the No. 1 support rod 55 is rotatably connected to the lower surface of the connecting plate 5. The upper surface of the base plate 2 is provided with a No. 2 slide groove 56 below the No. 1 telescopic rod 52, and the No. 2 slide groove 56 is slidably connected to the No. 2 support rod 57, and one end of the No. 2 support rod 57 is rotatably connected to the lower surface of the mounting post 51. A rotating structure is provided between the mounting platform 3 and the connecting plate 5. When working, the existing adjustment device uses a lifting device to lift the adjustment device and the jacking pipe as a whole, and then directly starts the adjustment device to adjust the angle of the jacking pipe. As a result, the jacking pipe will be suspended in the air and shake during the angle adjustment process. Impact from foreign objects and wind may cause the jacking pipe as a whole to shake significantly, resulting in poor stability of the adjustment device, low adjustment efficiency and low accuracy.

[0013] When in use, the adjusting device is hoisted as a whole to the bottom of the working pit by the lifting device, and then the bottom plate 2 is fixed to the bottom of the working pit, thereby fixing the adjusting device as a whole to the bottom of the working pit, and then the pipe jacking machine body 1 or the pipe is lifted by the lifting device, and then the pipe jacking machine body 1 or the pipe is hoisted and placed on the two guide rail plates 4, and then the connection between the lifting device and the pipe jacking machine body 1 or the pipe is released, so that the pipe jacking machine body 1 or the pipe is supported by the adaptation component, so that the pipe jacking machine body 1 or the pipe and the two guide rail plates 4 are kept in the same horizontal direction, ensuring that the pipe jacking machine body 1 or the pipe moves with the two guide rail plates 4, and then a group of No. 1 telescopic rods 52 on one side is started, and a group of No. 1 telescopic rods 52 on one side is extended, and then the No. 1 fixing seat 53 is used to rotate and connect with one side of the lower surface of the connecting plate 5, and the mounting column 51 is rotated and connected with one side of the upper surface of the bottom plate 2 to cooperate with each other to connect the connecting plate 5. The flat plate 5 rotates upward around one side of the connecting flat plate 5, and at the same time drives the mounting platform 3 and the two guide plates 4, thereby driving one side of the pipe jacking machine body 1 or the pipeline to rotate upward, and adjusting the vertical angle of the pipe jacking machine body 1 or the pipeline, and by starting the rotating structure to drive the mounting platform 3 to rotate, thereby driving the two guide plates 4 to rotate, and then driving the pipe jacking machine body 1 or the pipeline to rotate, and adjusting the horizontal angle of the pipe jacking machine body 1 or the pipeline, by fixing the adjustment device at the bottom of the working pit and then hoisting the pipe jacking machine body 1 or the pipeline onto the two guide plates 4, the pipe jacking machine body 1 or the pipeline is prevented from shaking during the angle adjustment, and then the adjustment component and the rotating structure are started to adjust the angle of the pipe jacking machine body 1 or the pipeline, thereby improving the overall stability of the adjustment device, thereby improving the stability, adjustment efficiency and adjustment accuracy of the angle adjustment of the pipe jacking machine body 1 or the pipeline. When a group of No. 1 telescopic rods 52 on one side are extended and drive one side of the connecting plate 5 to rotate upward, a group of mounting columns 51 and No. 1 telescopic rod 52 on one side are rotated upward at the same time. Then, through the cooperation of No. 1 support rod 55 and No. 1 slide groove 54, the No. 1 fixing seat 53, No. 1 telescopic rod 52, mounting column 51 and No. 1 support rod 55 form a triangular structure. At the same time, through the cooperation of No. 2 support rod 57 and No. 2 slide groove 56, the No. 2 support rod 57, the base plate 2 and the mounting column 51 form a triangular structure, thereby improving the stability between the base plate 2 and the connecting plate 5.

[0014] like Figures 1 to 4As shown, the rotating structure includes a No. 1 groove 58 opened at the center position of the upper surface of the connecting plate 5, and the lower end of the mounting platform 3 is rotatably connected to the inside of the No. 1 groove 58, and the lower side of the inner circle of the No. 1 groove 58 is fixedly connected to an internal tooth groove 582, and the center position of the lower end of the inner wall of the No. 1 groove 58 is fixedly connected to a positioning rod 581, and the positioning rod 581 extends into the mounting platform 3 and is rotatably connected to the mounting platform 3, and a No. 2 groove 583 is opened on one side of the lower surface of the mounting platform 3, and a No. 1 gear 584 is rotatably connected to the inside of the No. 2 groove 583, and the No. 1 gear 584 is meshed with the internal tooth groove 582, and a motor 585 is fixedly connected to the upper surface of the mounting platform 3 above the No. 1 gear 584, and the output end of the motor 585 is fixedly connected to the No. 1 gear 584; During operation, the No. 1 gear 584 is driven to rotate by starting the motor 585, and then the No. 1 gear 584 is engaged with the inner tooth groove 582, and since the connecting plate 5 is fixed and cannot rotate, the mounting platform 3 is driven to rotate. At the same time, through the cooperation between the positioning rod 581 and the mounting platform 3, the mounting platform 3 rotates around the positioning rod 581, thereby driving the guide plate 4 to rotate, and then driving the jacking machine body 1 or the pipeline to rotate, and adjusting the horizontal angle of the jacking machine body 1 or the pipeline, thereby quickly and accurately adjusting the horizontal angle of the jacking machine body 1 or the pipeline, thereby improving the adjustment efficiency of the adjustment device.

[0015] like Figures 2 to 4 As shown, the upper surface of the connecting plate 5 is fixedly connected to a ring block 586, and the ring block 586 and the first groove 58 are concentric with each other. The lower surface of the mounting platform 3 is provided with a third slide groove 587 adapted to the ring block 586, and the ring block 586 is slidably connected to the inner portion of the third slide groove 587; During operation, when the installation platform 3 rotates around the positioning rod 581, the annular block 586 slides in the third slide groove 587 at the same time, and the cooperation between the annular block 586 and the third slide groove 587 prevents the two sides of the installation platform 3 from warping after long-term use, so that the installation platform 3 remains flat.

[0016] like Figures 3 to 6As shown, the adaptation component includes a group of No. 1 mounting grooves 6 opened on the upper surface of the guide rail plate 4, and a No. 1 rotating block 61 is rotated inside the No. 1 mounting groove 6. Two rotating grooves 62 are opened on the upper surface of the No. 1 rotating block 61, and a placement bin 63 is rotatably connected inside the rotating groove 62. A fixed component is provided between the two placement bins 63, and a support roller 64 is rotatably connected inside the placement bin 63. A No. 3 groove 65 is opened at the lower end of the inner wall of the No. 1 mounting groove 6, and a boss 66 is fixedly connected to the lower surface of the No. 1 rotating block 61, and the boss 66 is located inside the No. 3 groove 65. A group of No. 1 springs 67 are provided between the lower surface of the boss 66 and the lower end of the inner wall of the No. 3 groove 65. A pair of the guide rail plates 4 is provided with two, and a moving component is provided between the two guide rail plates 4; During operation, when the pipe jacking machine body 1 or pipe is placed on the two guide rails 4, the support roller 64 on the first rotating block 61 first contacts the outer surface of the pipe jacking machine body 1 or pipe, and then the pipe jacking machine body 1 or pipe continues to move downward, thereby driving the first rotating block 61 to rotate in the first mounting groove 6, so that the two support rollers 64 on the first rotating block 61 simultaneously fit with the outer surface of the pipe jacking machine body 1 or pipe, thereby supporting the pipe jacking machine body 1 or pipe and preventing the pipe jacking machine body 1 or pipe from shaking left and right. Moreover, through the rotation setting of the first rotating block 61, the two support rollers 64 on the first rotating block 61 can fit with the outer surface of the pipe jacking machine body 1 or pipe of different diameters, thereby supporting pipe jacking machine bodies 1 or pipes of different diameters, thereby improving the applicability of the adjustment device. The moving component is then started to drive the two guide rails 4 to move in opposite directions at the same time, thereby adjusting the distance between the two guide rails 4, facilitating the support of pipe jacking machine bodies 1 or pipes of different diameters, thereby improving the applicability of the adjustment device. Then, through the cooperation of the placement bin 63 and the rotating groove 62, the placement bin 63 drives the support roller 64 to rotate inside the rotating groove 62, so that when the support roller 64 is in contact with the outer cylindrical surface of the pipe jacking machine body 1 or the pipeline, the contact position of the support roller 64 and the pipe jacking machine body 1 or the pipeline is maintained in the middle position of the support roller 64, preventing the contact position of the support roller 64 and the pipe jacking machine body 1 or the pipeline from moving to the edge position of the support roller 64, applying greater pressure on the edge position of the support roller 64, causing the support roller 64 to collapse, affecting the normal use of the support roller 64, thereby ensuring the support effect of the support roller 64 on the pipe jacking machine body 1 or the pipeline. Because the support roller 64 is rotatably connected to the interior of the placement bin 63, when the pipe jacking machine body 1 or the pipeline is pushed into the soil layer on the two guide rails 4, the support roller 64 rotates simultaneously with the movement of the pipe jacking machine body 1 or the pipeline, reducing the friction between the pipe jacking machine body 1 or the pipeline and the support roller 64 during movement, thereby facilitating the forward movement of the pipe jacking machine body 1 or the pipeline. Furthermore, through the cooperation of the No. 3 groove 65, the boss 66, and the No. 1 spring 67, when the pipe jacking machine body 1 or the pipeline drives the No. 1 rotating block 61 to rotate, the No. 1 spring 67 is stretched. When the pipe jacking machine body 1 or the pipeline moves away from the No. 1 rotating block 61, the stretched No. 1 spring 67, due to its own elastic potential energy, drives the No. 1 rotating block 61 to rotate and return to its original position, so that the support roller 64 on the No. 1 rotating block 61 remains upward, so that the support roller 64 first contacts the outer surface of the pipe jacking machine body 1 or the pipeline.

[0017] like Figures 3 and 4As shown, the moving assembly includes a straight plate 68 fixedly connected to the middle position of the upper surface of the mounting platform 3, a group of No. 2 telescopic rods 681 are fixedly connected to both sides of the outer surface of the straight plate 68, and the No. 2 telescopic rods 681 are fixedly connected to the upper surface of the mounting platform 3, one end of the No. 2 telescopic rods 681 is fixedly connected to the outer surface of the guide rail plate 4, and both ends of the upper surface of the mounting platform 3 are fixedly connected to placement boxes 682, and the two placement boxes 682 are fixedly connected to both ends of the straight plate 68, the middle position of the placement boxes 682 are rotatably connected to the No. 2 gear 683, the two sides of the placement boxes 682 are slidably connected to the racks 684, and the ends of the two placement boxes 682 away from each other are respectively fixedly connected to the two guide rail plates 4, and the No. 2 gear 683 is meshed with the two racks 684; During operation, the second telescopic rods 681 on either side of the straight plate 68 are activated to drive the two guide rails 4 to move synchronously in opposite directions, thereby adjusting the distance between the two guide rails 4. This facilitates support for pipe jacking machine bodies 1 or pipes of varying diameters, improving the applicability of the adjustment device. Furthermore, the meshing connection between the second gear 683 and the two racks 684 ensures that the two guide rails 4 maintain synchronous movement, preventing one guide rail 4 from moving farther than the other. This ensures that the centerlines of the two guide rails 4 coincide with the rotation axis of the mounting platform 3, thus ensuring the accuracy of the adjustment assembly.

[0018] like Figures 3 to 5 As shown, four symmetrical T-shaped slots 685 are provided on the lower surfaces of the two guide rail plates 4, and a T-shaped slide bar 686 adapted to the T-shaped slot 685 is fixedly connected to the upper surface of the mounting platform 3, and the T-shaped slide bar 686 is slidably connected to the inside of the T-shaped slot 685; During operation, the sliding connection between the T-slot 685 and the T-slide bar 686 limits the movement of the two guide rail plates 4 to prevent them from detaching from the mounting platform 3. At the same time, the lower surfaces of the two guide rail plates 4 are kept in contact with the upper surface of the mounting platform 3 to prevent the two guide rail plates 4 from tilting, thereby ensuring the normal use of the two guide rail plates 4.

[0019] like Figures 5 to 7As shown, the fixing assembly includes an external tooth groove 75 opened on one side where the outer circumferences of the two placement bins 63 are close to each other, and a No. 2 mounting groove 7 is commonly opened between the inner circumferences of the two rotating grooves 62, and the No. 2 mounting groove 7 is close to the two rotating grooves 62, and the middle position inside the No. 2 mounting groove 7 is slidably connected to the No. 1 slider 72, and the middle position inside the No. 2 mounting groove 7 is rotatably connected to the threaded rod 71, and the threaded rod 71 passes through the No. 1 slider 72 and is threadedly connected to the No. 1 slider 72, and both sides of the No. 1 slider 72 in the No. 2 mounting groove 7 are slidably connected with tooth blocks 73, and both sides of the No. 1 slider 72 are rotatable. A connecting plate 74 is connected, and the other sides of the two connecting plates 74 are rotatably connected to the tooth blocks 73 respectively. A third mounting groove 76 is provided at the lower end of the inner wall of the No. 2 mounting groove 7. The lower end of the threaded rod 71 extends into the No. 3 mounting groove 76 and is fixedly connected to a universal coupling 77. The other end of the universal coupling 77 is fixedly connected to a No. 1 straight rod 78. One end of the No. 1 straight rod 78 passes through the outer surface of the No. 1 rotating block 61 and is fixedly connected to a hexagonal block 79. A hexagonal groove is provided on one side of the outer surface of the hexagonal block 79. A limiting component is provided on the side of the outer circumference of the No. 1 straight rod 78 close to the hexagonal block 79. During operation, when the support roller 64 is in contact with the main body 1 of the pipe jacking machine and the outer surface of the pipe, the placement bin 63 is driven to rotate in the rotation groove 62, so that the contact position of the support roller 64 and the main body 1 of the pipe jacking machine or the pipe is maintained in the middle position of the support roller 64, and then the hexagonal block 79 is rotated with a wrench to drive the No. 1 straight rod 78 to rotate clockwise, and then the threaded rod 71 is driven to rotate at the same time through the universal coupling 77, and the threaded rod 71 is engaged with the No. 1 slider 72, thereby driving the No. 1 slider 72 to move upward, and then through Through the cooperation of the connecting plate 74 and the tooth block 73, the two tooth blocks 73 are driven to move toward the rotating groove 62, so that the two tooth blocks 73 engage with the two outer tooth grooves 75, thereby fixing the two placement bins 63 to prevent the placement bins 63 from driving the rotating groove 62 to rotate, so that the two support rollers 64 are adapted to the outer cylindrical surface of the jacking machine body 1 or the pipeline, so that when the subsequent pipeline is placed on the support roller 64, the pipeline directly fits with the middle position of the support roller 64 to prevent the pipeline from colliding with the edge position of the support roller 64.

[0020] like Figures 6 to 8As shown, the limiting assembly includes a ratchet 8 fixedly connected to one side of the outer cylindrical surface of the No. 1 straight rod 78, and the ratchet 8 is close to the hexagonal block 79. The No. 1 rotating block 61 is provided with a No. 4 mounting groove 81 adapted to the ratchet 8. The No. 4 mounting groove 81 is located above the ratchet 8 and is rotatably connected to a pawl 82, and the pawl 82 is engaged with the ratchet 8. The No. 4 mounting groove 81 is located above the pawl 82 and is fixedly connected to the pawl 83. The lower surface of the pawl spring 83 is in contact with the upper surface of the pawl 82. The pawl 82 is engaged with the ratchet 8. A side of the outer surface away from the spring 83 is fixedly connected to a circular block 84. A fourth slide groove 85 is opened on one side of the upper end of the inner wall of the fourth mounting groove 81, and the fourth slide groove 85 is located directly above the circular block 84. A trapezoidal slider 87 is slidably connected to the inside of the fourth slide groove 85. A trapezoidal plate 86 is slidably connected to the inside of the circular block 84, and the upper end of the trapezoidal plate 86 extends into the inside of the fourth slide groove 85. A second straight rod 88 is fixedly connected to one side of the outer surface of the trapezoidal slider 87, and one end of the second straight rod 88 passes through the outer surface of the first rotating block 61. During operation, the No. 1 straight rod 78 rotates clockwise to drive the No. 1 slider 72 to move upward, so that the two tooth blocks 73 are respectively engaged with the two outer tooth grooves 75. Then, through the cooperation of the ratchet 8, the pawl 82 and the spring 83, the ratchet 8 can only rotate in one direction, so that the No. 1 straight rod 78 can only rotate clockwise, preventing the No. 1 straight rod 78 from rotating counterclockwise, causing the tooth block 73 to separate from the outer tooth groove 75, thereby improving the use effect of the fixing component. When it is necessary to release the fixed connection between the tooth block 73 and the outer tooth groove 75, the trapezoidal slider 87 is driven to move into the inner part of the No. 4 slide groove 85 by pushing the No. 2 straight rod 88, thereby driving the trapezoidal plate 86 to move downward, and then through the cooperation of the trapezoidal plate 86 and the circular block 84, the circular block 84 is driven to rotate downward, thereby driving the pawl 82 to rotate upward, so that the pawl 82 is separated from the ratchet 8, releasing the restriction on the ratchet 8, and then the hexagonal block 79 is rotated counterclockwise, thereby driving the tooth block 73 to move away from the outer tooth groove 75, so that the tooth block 73 is separated from the outer tooth groove 75, thereby improving the use effect of the limiting component.

[0021] like Figures 6 to 8 As shown, a spring 89 is provided on the outer surface of the No. 1 straight rod 78 near the ratchet 8, and a No. 5 mounting slot 810 adapted to the spring 89 is provided in the No. 1 rotating block 61; During operation, when the No. 1 straight rod 78 is rotated clockwise, the spring 89 inside the No. 5 mounting slot 810 is tightened at the same time. Then, when the pawl 82 is separated from the ratchet wheel 8, the elastic potential energy of the spring 89 automatically drives the No. 1 straight rod 78 to rotate counterclockwise, thereby driving the tooth block 73 to separate from the outer tooth slot 75, thereby improving the working efficiency of the limiting assembly.

[0022] like Figures 5 to 9As shown, one side of the outer surface of the two guide rail plates 4 is provided with a clamping assembly, and the clamping assembly includes two rotating frames 9 rotatably connected to the upper side of one side of the outer surface of the guide rail plate 4, and the rotating frame 9 is located on the side of the guide rail plate 4 away from the rack 684, and the outer surface of the guide rail plate 4 is located below the rotating frame 9 and is rotatably connected to a No. 2 fixed seat 93, one side of the outer surface of the No. 2 fixed seat 93 is fixedly connected to a No. 3 telescopic rod 92, and one end of the No. 3 telescopic rod 92 is fixedly connected to the rotating frame 9, and two No. 2 rotating blocks 91 are provided on the upper end of the rotating frame 9, and the structure of the No. 2 rotating block 91 is the same as that of the No. 1 rotating block 61; During operation, after the pipe jacking machine body 1 or the pipeline is placed on the No. 1 rotating block 61, the No. 3 telescopic rod 92 is started to extend the No. 3 telescopic rod 92, and then the No. 3 telescopic rod 92 cooperates with the guide plate 4, and the rotating frame 9 and the guide plate 4 to drive the rotating frame 9 to rotate upward, and at the same time drives the two No. 2 rotating blocks 91 to move, so that the No. 2 rotating blocks 91 are in contact with the upper side of the outer cylindrical surface of the pipe jacking machine body 1 or the pipeline, and the No. 2 rotating blocks 91 have the same structure as the No. 1 rotating block 61. Through the cooperation of the No. 2 rotating blocks 91 and the No. 1 rotating blocks 61, the pipe jacking machine body 1 or the pipeline is clamped, thereby preventing the pipe jacking machine body 1 or the pipeline from tilting on one side when it is pushed into the soil layer, thereby improving the stability of the pipe jacking machine body 1 or the pipeline during the jacking process.

[0023] Working principle: First, the adjustment device is hoisted as a whole to the bottom of the working pit through the lifting device, and then the bottom plate 2 is fixed to the bottom of the working pit. Then, according to the diameter of the pipe jacking machine body 1 or the pipeline, the moving component is started to adjust the distance between the two guide plates 4. Then, the pipe jacking machine body 1 or the pipeline is lifted by the lifting device and placed on the guide plate 4, thereby starting the adaptation component to make the middle position of the support roller 64 fit with the outer cylindrical surface of the pipe jacking machine body 1 or the pipeline, and then the pipe jacking machine body 1 or the pipeline is supported. Then, the fixing component is started to fix the position of the support roller 64, and then the clamping component is started to drive the No. 2 rotating block 91 to move , so that the No. 2 rotating block 91 is fitted with the upper side of the outer cylindrical surface of the pipe jacking machine body 1 or the pipeline, and the No. 2 rotating block 91 and the No. 1 rotating block 61 cooperate to clamp the pipe jacking machine body 1 or the pipeline, and then start one group of the No. 1 telescopic rods 52 in the two groups of No. 1 telescopic rods 52 to push one side of the connecting plate 5 to rotate upward, thereby driving one side of the pipe jacking machine body 1 or the pipeline to rotate upward, and adjusting the vertical angle of the pipe jacking machine body 1 or the pipeline, and then start the rotating structure to drive the mounting platform 3 to rotate, thereby driving the pipe jacking machine body 1 or the pipeline to rotate, and adjusting the horizontal angle of the pipe jacking machine body 1 or the pipeline.
