Description
Technical Field

[0002] In the process of underground engineering construction, pipe jacking is one of the commonly used construction methods for small and medium diameter tunnels in soft soil layers. It has the characteristics of fast construction speed and strong economy. During pipe jacking construction, the pipe jacking machine is generally installed in the working well, and the subsequent pipe sections usually follow the pipe jacking machine, so that the pipe jacking machine pushes the machine head into the soft soil layer by pushing the pipe section, and then relays the jacking to form an underground tunnel. At present, the commonly used method of pipe jacking construction is to use laser rangefinders, total stations and other equipment for measurement, combined with manual calculation and adjustment to correct the deviation, so that the pipe section is pushed into the soft soil layer to complete the construction operation.
[0003] A patent with publication number CN114439486B discloses a micro pipe jacking machine. This patent arranges a drill rod straightener and a drill rod straightener structure. The drill rod straightener can adapt to the rotation and movement of the drill rod, avoiding damage caused by friction with the drill rod, thereby ensuring the life of the drill rod, reducing external force intervention, and increasing construction accuracy. Through the structural arrangement of the bracket, the bracket further avoids friction with the track plate while meeting the functional requirements of pushing the drill rod, and at the same time can provide good support for the power clamp. Through the arrangement of the height adjustment component, the four corners of the invention are adjustable in height, avoiding errors caused by the uneven bottom of the construction well.
[0004] There are still some problems in the actual application of the above scheme. Due to the complex geological conditions and the changeable construction environment, if the head of the pipe jacking machine is not fine-tuned during the jacking process, it will easily cause the pipes in the soft soil layer to not be jacked in a straight line, resulting in deviations in the jacking route and affecting the overall quality of the project. In addition, the measurement accuracy of the traditional method is limited by the accuracy of the equipment and the proficiency of the operator, resulting in a lot of time being wasted on measuring whether the pipes jacked into the soft soil layer are in a straight line, which in turn results in a lot of time being wasted on correcting the deviated pipes, making it difficult to meet the high-precision and high-efficiency construction requirements.

[0020] The beneficial effects of the present invention are as follows:
[0021] 1. A pipe jacking machine measuring and jacking correction device according to the present invention places a pipe fitting on a mounting bracket 1, and drives the bracket adjustment component to adjust and support the pipe fitting according to different diameters, and adjusts the position of the pipe fitting on the mounting bracket, and then controls the pipe fitting and the machine head for installation and docking. After the installation and docking is completed, the machine head is lifted up and moved upward by driving the correction component to adjust between 10 and 15 degrees, and then the piston rod end of the hydraulic cylinder is used to drive the jacking slide column to slide inside the mounting bracket, thereby driving the jacking adjustment component to push the pipe fitting against the machine head to jack into the soft soil layer. When the machine head is pushed into the soft soil layer by the pipe fitting, the pipe fitting or the machine head is fine-tuned by driving the correction component, and then the pipe fitting in the soft soil layer is corrected as needed, thereby solving the problem that the existing pipe jacking machine measuring and jacking correction device has complex geological conditions and changeable construction environment. If the machine head is not fine-tuned during the jacking process of the pipe jacking machine, it will easily cause the pipe fitting in the soft soil layer to deviate, thereby affecting the overall quality of the project.
[0022] 2. The measuring and jacking correction device of a pipe jacking machine described in the present invention adjusts the spacing between the rubber jacking blocks by driving the jacking adjustment component, thereby facilitating the rubber jacking block to abut against the pipe fitting, and then uses the piston rod end of the hydraulic cylinder to drive the jacking slide column to slide inside the mounting frame, and drives the pushing plate to slide out of the storage groove, so that the rubber jacking block abuts against one end of the pipe fitting, and at the same time pushes the pipe fitting to push against the machine head into the soft soil layer, thereby solving the problem that the existing measuring and jacking correction device of the pipe jacking machine is inconvenient to adjust the abutting position according to the diameter of the pipe fitting in the construction of underground projects, which will cause the pipe jacking machine to be able to perform construction operations only according to the adapted pipe fitting, thereby affecting the practicality of the pipe jacking machine, and placing a push plate between the jacking block and the pipe fitting, and using the push plate to push the pipe fitting into the soft soil layer, it is impossible to control the uniformity of the jacking force of the pipe fitting, resulting in deviation of the pipe fitting in the soft soil layer.
[0023] 3. The measuring and jacking deviation correction device of the pipe jacking machine described in the present invention drives the rubber jacking block to abut the pipe fitting to be jacked into the soft soil layer. When the rubber jacking block abuts the pipe fitting to be jacked, the pushing plate will abut the pushing round block and push the T-shaped sliding column to slide in the inner cavity of the rotating cylinder, thereby pushing the pipe fitting to be adjusted and jacked into the soft soil layer, thereby realizing quantitative jacking of the pipe fitting into the soft soil layer and preventing the deviation of the jacking caused by excessive transportation of the pipe fitting. After the jacking is completed, the T-shaped sliding column is bounced up by the spring, and the T-shaped sliding column drives the pushing round block to reset, thereby When the next section of the pipe is to be jacked in, and when jacking pipes of different lengths, the threaded rod is driven to rotate and the position of the push plate in the inner cavity of the rotating cylinder is adjusted, the progress of the T-type sliding column in the inner cavity of the rotating cylinder can be effectively limited, thereby adjusting the progress of the rubber jacking block to push the pipe into the soft soil layer, thereby solving the problem of the existing pipe jacking machine measurement and jacking correction device that the length of each section of the pipe pushed into the soft soil layer needs to be precisely controlled. If the jacking length is too long, the machine head will be deviated, making it difficult to perform correction operations later. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The deviation correction component 6 includes a bidirectional screw 61 rotatably connected to one side of the inner cavity of the mounting bracket 1, the outer thread of the bidirectional screw 61 is connected to two U-shaped sliders 62, and the inner cavities of the two U-shaped sliders 62 are both rotatably connected to support rollers 63, and the U-shaped sliders 62 slide in contact with the inner wall of the mounting bracket 1;
[0046] The bracket adjustment assembly 4 includes four L-shaped sliders 47 sliding in the inner cavity of the mounting bracket 1, and the four L-shaped sliders 47 are symmetrically arranged in pairs, and are fixedly connected to each other by connecting rods 48 to ensure balance;
[0047] The jacking adjustment assembly 9 includes a push plate 91 sliding in the inner cavity of the storage groove 10, and the push plate 91 is fixedly connected to the jacking slide column 14. A laser measuring probe 16 is arranged in the middle of one side of the push plate 91, and the laser measuring probe 16 cooperates with the internal receiver of the machine head to realize jacking calibration.
[0048] Specifically, in the prior art, due to the complex geological conditions and the changeable construction environment, if the head of the pipe jacking machine is not fine-tuned during the jacking process, it will easily cause the pipes in the soft soil layer to not be pushed in a straight line, resulting in deviations in the jacking route, affecting the overall quality of the project. In addition, the measurement accuracy of the traditional method is limited by the accuracy of the equipment and the proficiency of the operator, and the correction process is time-consuming, making it difficult to meet the requirements of high-precision and high-efficiency construction.
[0049] The present invention places the pipe fitting on the mounting bracket 1, and drives the four L-shaped sliders 47 in the inner cavity of the mounting bracket 1 to move toward each other, so that the four L-shaped sliders 47 are moved synchronously by the connecting rod 48, so as to adjust the support according to the pipe fittings of different diameters, and adjust the position of the pipe fitting on the mounting bracket 1, and then control the pipe fitting to be installed and docked with the machine head. After the installation and docking are completed, the two-way screw rod 61 is driven to rotate, and the two-way screw rod 61 is threaded to drive the two U-shaped sliders 62 to move toward each other. The U-shaped slider 62 moves closer, and then the support roller 63 moves synchronously, and then the support roller 63 is used to lift the machine head and move it upward by adjusting 10 to 15 degrees, and then the piston rod end of the hydraulic cylinder is used to drive the jacking slide column 14 to slide inside the mounting frame 2, and the jacking slide column 14 drives the push plate 91 to slide out of the storage groove 10, so that the push plate 91 is fitted with one end of the pipe fitting, and at the same time, the push plate 91 is used to push the pipe fitting to push the machine head horizontally into the soft soil layer, and the pipe fitting is used to push the machine head into the soft soil layer. During jacking, the two U-shaped sliders 62 are driven by the bidirectional screw rod 61 to thread and move away from or towards each other, and the U-shaped slider 62 drives the support roller 63 to fine-tune the pipe or the machine head upward or downward by 10 to 15 degrees, and then the pipes in the soft soil layer are corrected as needed to prevent the middle pipes that are pushed into the soft soil layer from deviation. In addition, the jacking position can be calibrated in real time by using the laser measuring probe 16 in conjunction with the receiver inside the machine head. The receiver adopts a disc laser receiver. After the laser measuring probe 16 emits a laser that deviates from the center point of the disc laser receiver, the disc laser receiver will transmit a signal to the shell computer or controller to display the deviation angle of the machine head jacking, and then determine whether a correction operation is needed according to the deviation angle, thereby solving the problem that the existing pipe jacking machine measurement and jacking correction device has complex geological conditions and changeable construction environment. If the machine head is not fine-tuned during the jacking process of the pipe jacking machine, it will easily cause the pipes in the soft soil layer to deviate, affecting the overall quality of the project.
[0050] like Figures 6 to 8 As shown, four cross limit grooves 96 are opened on one side of the push plate 91, and a rotating groove 92 is opened at the bottom of the inner cavity of the cross limit groove 96, and a cross rotating frame 93 is rotatably connected to the inner cavity of the rotating groove 92, and a pull rod 94 is rotatably connected to one end of the cross rotating frame 93, and a cross sliding column 95 is rotatably connected to one end of the pull rod 94, and the cross sliding column 95 is slidably connected to the cross limit groove 96, and a rubber jacking block 97 is fixed to one end of the cross sliding column 95.
[0051] Specifically, when jacking pipes of different diameters, the cross rotating frame 93 is driven to rotate, and the cross rotating frame 93 drives the pull rod 94 to rotate, and the pull rod 94 pulls the cross slide column 95 to slide in the inner cavity of the cross limit groove 96, so that the cross slide column 95 drives the rubber jacking block 97 to move closer to each other for adjustment, so that the rubber jacking block 97 can abut against the pipe, and then the piston rod end of the hydraulic cylinder is used to drive the jacking slide column 14 to slide inside the mounting frame 2, and the jacking slide column 14 drives the push plate 91 to slide out of the storage groove 10, so that the rubber jacking The block 97 is in contact with one end of the pipe fitting, and the rubber jacking block 97 is used to push the pipe fitting against the machine head and jack it into the soft soil layer, thereby solving the problem that the existing pipe jacking machine measurement and jacking correction device is inconvenient to adjust the abutment position according to the diameter of the pipe fitting during underground engineering construction, which will cause the pipe jacking machine to be able to perform construction operations only according to the adapted pipe fitting, thereby affecting the practicability of the pipe jacking machine. If a push plate is placed between the jacking block and the pipe fitting and the push plate is used to push the pipe fitting into the soft soil layer, the uniformity of the jacking force of the pipe fitting cannot be controlled, resulting in deviation of the pipe fitting in the soft soil layer.
[0052] like Figure 2 , Figure 4 and Figure 8 As shown, a servo motor 7 is installed at one end of the mounting bracket 1, and the output shaft end of the servo motor 7 is fixedly connected to the bidirectional screw rod 61. A plurality of hydraulic cylinder slots 15 are provided on one side of the pushing frame 3 for clamping the piston rod of the pipe jacking machine.
[0053] like Figure 1 , Figure 2 and Figure 4 As shown, the lower end surface of the mounting bracket 1 is rotatably connected to a rotating column 41, the rotating column 41 is externally fixedly connected to two worms 42, and the two worms 42 are externally meshingly connected to two worm wheels 43, and each worm wheel 43 is internally fixedly connected to a bidirectional threaded rod 45, the bidirectional threaded rod 45 is rotatably connected to the inner cavity of the mounting bracket 1, and an L-shaped slider 47 is threadedly connected to the bidirectional threaded rod 45.
[0054] like Figure 3 and Figure 4 As shown, a crank 44 is fixedly connected to one end of the rotating column 41 , a fixing frame 46 is installed at the lower end of the mounting bracket 1 , and one end of the rotating column 41 is rotatably connected to the fixing frame 46 .
[0055] Specifically, by driving the crank 44 to rotate, and making the crank 44 drive the rotating column 41 to rotate, and at the same time drive the worm 42 to rotate, while the worm 42 will engage the transmission worm wheel 43 to rotate during the rotation process, and then drive the two-way threaded rod 45 to rotate, and at the same time, the two-way threaded rod 45 threaded transmission L-shaped sliders 47 move closer to each other, and then make the L-shaped sliders 47 move closer to each other, so as to adjust the height of the pipe fittings to be lifted, so that the pipe fittings can be better pushed into the soft soil layer, and the spacing can be adjusted according to the pipe fittings of different diameters, so as to facilitate the lifting construction operation of the pipe fittings, thereby improving the convenience of using the measurement and jacking correction device of the pipe jacking machine.
[0056] Embodiment 2
[0057] like Figure 1 , Figure 4 and Figure 5 As shown, a bracket assembly 5 is rotatably arranged between the L-shaped sliders 47, and the bracket assembly 5 includes a rotating cylinder 51 rotatably connected to the inside of the L-shaped slider 47, a spring 52 is arranged in the inner cavity of the rotating cylinder 51, one end of the spring 52 abuts against a T-shaped slide column 53, one end of the T-shaped slide column 53 is fixedly connected to a pushing round block 54, and the T-shaped slide column 53 is rotatably connected to the L-shaped slider 47.
[0058] like Figure 1 and Figure 5 As shown, a threaded rod 55 is rotatably connected inside one end of the rotating cylinder 51, and the threaded rod 55 is threadedly connected to the L-shaped slider 47. The threaded rod 55 is located at one end of the inner cavity of the rotating cylinder 51 and is rotatably connected to a push plate 56, and one end surface of the push plate 56 abuts against the spring 52.
[0059] Specifically, when the pipe is pushed forward, the rubber pushing block 97 is driven to push against the pipe to push into the soft soil layer. When the rubber pushing block 97 pushes against the pipe, the pushing plate 91 will push against the pushing block 54, and the pushing block 54 pushes the T-shaped slide column 53 to slide in the inner cavity of the rotating cylinder 51. At the same time, the T-shaped slide column 53 squeezes the spring 52, thereby pushing the pipe to adjust and push into the soft soil layer, thereby realizing quantitative pushing of the pipe into the soft soil layer. Deviation in pushing is prevented due to excessive pipe transportation. When the pipe is pushed forward, the threaded rod 55 is driven to rotate and the threaded rod 55 drives the position of the push plate 56 in the inner cavity of the rotating cylinder 51, thereby effectively limiting the progress of the T-type sliding column 53 in the inner cavity of the rotating cylinder 51, thereby adjusting the progress of the rubber jacking block 97 to push the pipe into the soft soil layer, thereby solving the problem of the existing pipe jacking machine measurement and jacking correction device that the length of each section of the pipe pushed into the soft soil layer needs to be precisely controlled. If the jacking length is too long, the machine head will be deviated, making it difficult to perform correction operations later.
[0060] like Figure 1, Figure 2 and Figure 4 As shown, a quantitative jacking assembly 8 is provided at one end of the inner cavity of the mounting bracket 1, and the quantitative jacking assembly 8 includes two slide grooves 81 symmetrically opened on the inner wall of the mounting bracket 1, the inner cavities of the two slide grooves 81 are fixedly connected with a first fixed slide column 82, the first fixed slide column 82 is slidably connected to the outside of the first fixed slide column 83, and a second fixed slide column 84 is fixed between the first slide blocks 83, the second fixed slide column 84 is slidably connected to two second slide blocks 85, and the second slide block 85 is rotatably connected to the pushing block 54.
[0061] like Figures 3 to 5 As shown, a fixing rod 11 is installed in one side of the second slider 85, a scale slot 12 is opened on one side of the mounting bracket 1, the fixing rod 11 is slidably connected with the scale slot 12, and a pointer 13 is installed at one end of the fixing rod 11 located in the inner cavity of the scale slot 12.
[0062] like Figures 6 to 9 As shown, one end of the cross rotating frame 93 passes through the pushing plate 91 and is fixedly connected to a tooth column 17, the outside of the tooth column 17 is meshed with a toothed disc 18, and the toothed disc 18 is rotatably connected to the pushing plate 91. A control motor is arranged inside the pushing plate 91, and the output shaft end of the control motor is fixedly connected to the toothed disc 18.
[0063] Specifically, when the pipe is pushed forward, the rubber jacking block 97 is driven to push the pipe into the soft soil layer. When the rubber jacking block 97 pushes forward against the pipe, the push plate 91 pushes the second slider 85, and the second slider 85 drives the second fixed slide post 84 to move. At the same time, the second slide post 84 drives the first slider 83 to slide outside the first fixed slide post 82, thereby controlling the pushing process of the pipe into the soft soil layer. When the push plate 91 pushes the second slider 85 forward, the laser measuring probe 16 is used in conjunction with the receiver inside the machine head to realize The jacking position is calibrated in reality, and the receiver adopts a disc laser receiver. After the laser measuring probe 16 emits a laser that deviates from the center point of the disc laser receiver, the disc laser receiver will transmit a signal to the shell computer or controller to display the deviation angle of the machine head jacking, and then determine whether correction operation is needed according to the deviation angle, thereby solving the problem that the existing pipe jacking machine measurement and jacking correction device is difficult to meet the high-precision and high-efficiency construction requirements due to the measurement accuracy of the traditional method is limited by the equipment accuracy and the proficiency of the operator, and the correction process is time-consuming.
[0064] The working principle is to place the pipe fitting on the mounting bracket 1 and drive the four L-shaped sliders 47 in the inner cavity of the mounting bracket 1 to move closer to each other, so that the four L-shaped sliders 47 are moved synchronously by the connecting rod 48, so as to adjust the support according to the pipe fittings of different diameters, and adjust the position of the pipe fitting on the mounting bracket 1, and then control the pipe fitting to be installed and docked with the machine head. After the installation and docking is completed, the two-way screw rod 61 is driven to rotate, and the two-way screw rod 61 is threaded to drive the two U-shaped sliders 62 to move closer to each other, so that the U-shaped slider 62 drives the support roller 63 to move synchronously, and then the support roller 63 is used to lift the machine head. Move upward and adjust between 10 and 15 degrees, then use the piston rod end of the hydraulic cylinder to drive the jacking slide column 14 to slide inside the mounting frame 2, and make the jacking slide column 14 drive the push plate 91 to slide out of the storage groove 10, so that the push plate 91 fits with one end of the pipe fitting, and at the same time use the push plate 91 to push the pipe fitting to push the machine head into the soft soil layer, and when using the pipe fitting to push the machine head into the soft soil layer, drive the two-way screw rod 61 to thread the two U-shaped sliders 62 to move away from or close to each other, and make the U-shaped slider 62 drive the support roller 63 to fine-tune the pipe fitting or the machine head, so as to correct the deviation of the pipe fitting pushed into the soft soil layer as needed;
[0065] When jacking pipes of different diameters, the cross rotating frame 93 is driven to rotate, and the cross rotating frame 93 drives the pull rod 94 to rotate, and the pull rod 94 pulls the cross slide column 95 to slide in the inner cavity of the cross limit groove 96, so that the cross slide column 95 drives the rubber jacking block 97 to move closer to each other for adjustment, so that the rubber jacking block 97 can abut against the pipe, and then the piston rod end of the hydraulic cylinder is used to drive the jacking slide column 14 to slide inside the mounting frame 2, and the jacking slide column 14 drives the push plate 91 to slide out of the storage groove 10, so that the rubber jacking block 97 abuts against one end of the pipe, and at the same time, the rubber jacking block 97 is used to push the pipe to push against the machine head into the soft soil layer;
[0066] When the pipe is pushed forward, the rubber jacking block 97 is driven to push the pipe into the soft soil layer. When the rubber jacking block 97 pushes the pipe, the push plate 91 will push the push round block 54, and the push round block 54 pushes the T-shaped slide column 53 to slide in the inner cavity of the rotating cylinder 51. At the same time, the T-shaped slide column 53 squeezes the spring 52, and then pushes the pipe to be adjusted and pushed into the soft soil layer, thereby realizing quantitative jacking of the pipe into the soft soil layer. The deviation of the jacking caused by excessive delivery of the pipe is prevented. When the pipes of different lengths are pushed forward, the threaded rod 55 is driven to rotate, and the threaded rod 55 drives the position of the push plate 56 in the inner cavity of the rotating cylinder 51, thereby effectively limiting the progress of the T-shaped slide column 53 in the inner cavity of the rotating cylinder 51, thereby realizing the progress of the rubber jacking block 97 against the pipe to push into the soft soil layer.
[0067] When the pipe is pushed forward, the rubber pushing block 97 is driven to push the pipe into the soft soil layer. When the rubber pushing block 97 pushes forward against the pipe, the push plate 91 pushes the second slider 85, and the second slider 85 drives the second fixed slide column 84 to move. At the same time, the second slide column 84 drives the first slider 83 to slide outside the first fixed slide column 82, thereby controlling the pushing process of the pipe into the soft soil layer. When the push plate 91 pushes the second slider 85 forward, the laser measuring probe 16 is used in conjunction with the internal receiver of the machine head to realize real-time calibration of the pushing position. The receiver adopts a disc laser receiver. After the laser measuring probe 16 emits a laser that deviates from the center point of the disc laser receiver, the disc laser receiver transmits a signal to the shell computer or controller to display the deviation angle of the machine head pushing, and then determines whether a correction operation is needed according to the deviation angle.
