Description

Technical Field

[0001] This utility model relates to the field of pipe jacking machine correction devices, and in particular to a pipe jacking machine correction device. Background Technology

[0002] The pipe jacking machine's deviation correction device is a key piece of equipment used in pipe jacking construction to correct deviations in the jacking machine's excavation direction. Its core function is to adjust the relative attitude between the jacking machine head and subsequent pipe sections, ensuring the pipe advances along the designed axis. During construction, when uneven strata, unbalanced jacking forces, or deviations in the jacking machine head's force cause the trajectory to deviate from the preset route, this device can actively apply directional forces, such as adjusting the thrust difference or tension in different directions, changing the jacking machine head's turning angle, and gradually correcting the deviation. It needs to work in conjunction with real-time monitoring data to dynamically respond to changes in deviation, ensuring the accuracy of pipe jacking construction and avoiding problems such as pipeline damage and ground subsidence caused by loss of directional control. It is an important auxiliary system for ensuring the quality and safety of underground pipeline projects.

[0003] However, the current pipe jacking machine correction devices have the following shortcomings: On the one hand, most correction devices have relatively simple functions and can only achieve horizontal or angular correction, which limits the correction range and makes it difficult to cope with complex working conditions; on the other hand, the existing correction devices have poor structural design, and the disassembly and installation process is cumbersome, which consumes a lot of manpower and time and is not conducive to the maintenance and efficient use of the equipment.

[0004] In response to this technical problem, this application proposes a pipe jacking machine correction device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pipe jacking machine correction device. The device aims to enable not only horizontal correction of the pipe jacking machine but also angular correction, thereby increasing the correction range and functionality of the correction device, and facilitating the disassembly and installation of the correction device by workers.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pipe jacking machine correction device includes a base plate, on which the pipe jacking machine is mounted. Two sliding grooves are formed on both the left and right sides of the top side of the base plate. A first threaded rod is rotatably connected inside each sliding groove. Metal plates are fixedly connected to the four corners of the top side of the base plate. A metal rod is bolted between the two metal plates. The metal rod and the first threaded rod are connected by clamping plates. A disassembly assembly is provided on the top side of the clamping plate to connect the metal rod and the top of the clamping plate together. Rubber pads are fixedly connected to adjacent sides of the two clamping plates. An angle adjustment assembly is provided inside the base plate to adjust the angle of the pipe jacking machine.

[0008] Furthermore, the disassembly assembly includes a positioning plate disposed on the top side of the clamping plate, an insert block is fixedly connected to the middle of the bottom side of the positioning plate, and a strip groove is opened on the top side of the outer wall of the metal rod, the insert block is inserted into the inside of the strip groove.

[0009] Furthermore, insert plates are fixedly connected to both the left and right sides of the bottom side of the positioning plate, and slots are opened on both the left and right sides of the top side of the clamping plate. The insert plates are inserted into the slots, and a pressing plate is connected to one side of the insert plate by a torsion spring.

[0010] Furthermore, a limiting block is fixedly connected to one side of the pressing plate, and a limiting groove is formed on one side inside the slot, with the limiting block engaging inside the limiting groove.

[0011] Furthermore, the angle adjustment component includes a slide rod slidably connected to the left and right sides inside the base plate, and positioning grooves are provided on both the left and right sides of the bottom side of the pipe jacking machine, with the top end of the slide rod inserted into the inside of the positioning groove.

[0012] Furthermore, a second threaded rod is rotatably connected to both the left and right sides inside the base plate, and the internal thread of the slide rod is connected to the outer wall of the second threaded rod. A second motor is installed on both the left and right sides inside the base plate.

[0013] Furthermore, the bottom end of the second threaded rod is fixedly connected to the drive end of the second motor, and grooves and arc-shaped slots are provided on both the left and right sides of the top side of the base plate, with multiple rollers rotatably connected inside the grooves and arc-shaped slots.

[0014] Furthermore, the bottom side of the clamping plate is threadedly connected to the outer wall of the first threaded rod, and the front and rear sides of the base plate are equipped with first motors, with the end of the first threaded rod fixedly connected to the drive end of the first motor.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the second threaded rod is driven to rotate by the second motor. Since the outer wall of the slide rod is provided with a limiting groove that matches the inside of the bottom plate, the second threaded rod will drive the slide rod to move up and down, so that the second threaded rod drives the slide rod to insert into or disengage from the bottom side of the pipe jacking machine. This allows the device to not only correct the horizontal deviation of the pipe jacking machine but also to correct the angle deviation, thereby improving the deviation correction range of the deviation correction device and improving its functionality.

[0017] 2. In this utility model, the insert plate is inserted into the slot so that the insert block is inserted into the strip groove. During this process, the limiting block will engage with the limiting groove, so that the top side of the clamp plate is connected to the metal rod. The insert block allows the clamp plate to slide on the metal rod, which facilitates the disassembly and installation of the correction device by the staff. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 and Figure 2This utility model provides an embodiment of a pipe jacking machine correction device, comprising a base plate 2, a pipe jacking machine 1 mounted on the top side of the base plate 2, two sliding grooves on both the left and right sides of the top side of the base plate 2, with a first threaded rod 6 rotatably connected inside the sliding grooves, and metal plates 3 fixedly connected at the four corners of the top side of the base plate 2. Metal rods 4 are bolted between the two metal plates 3, and the metal rods 4 and the first threaded rods 6 are connected by clamping plates 7. The first threaded rods 6 drive the clamping plates 7 to move horizontally, thereby pushing the pipe jacking machine 1 to move horizontally, thus correcting the horizontal deviation of the pipe jacking machine 1. Rubber pads 8 are fixedly connected to adjacent sides of the two clamping plates 7, as shown in the figure. Figure 5 and Figure 6 A positioning plate 13 is provided on the top side of the clamping plate 7. A plug 14 is fixedly connected to the middle of the bottom side of the positioning plate 13. A strip groove is opened on the top side of the outer wall of the metal rod 4. The plug 14 is inserted into the inside of the strip groove. Plug plates 15 are fixedly connected to the left and right sides of the bottom side of the positioning plate 13. Slots are opened on the left and right sides of the top side of the clamping plate 7. The plug 15 is inserted into the inside of the slot. A pressing plate 16 is connected to one side of the plug 15 through a torsion spring. A limiting block 17 is fixedly connected to one side of the pressing plate 16. A limiting groove is opened on one side of the slot. The limiting block 17 is engaged inside the limiting groove. By inserting the plug 15 into the slot, the plug 14 is inserted into the strip groove. During this process, the limiting block 14 is inserted into the slot. Block 17 will engage in the limiting groove, thereby connecting the top side of the clamping plate 7 to the metal rod 4. The clamping plate 7 can slide on the metal rod 4 through the insert block 14. When it is necessary to remove the metal rod 4 to facilitate the disassembly and assembly of the pipe jacking machine 1, first press the pressing plate 16 to make it rotate with the limiting block 17 in the slot, so that the limiting block 17 is disengaged from the limiting groove. Then pull the positioning plate 13 upward to make the insert plate 15 and the pressing plate 16 disengage from the slot. After that, use a screwdriver or other tools to tighten the bolts to remove the metal rod 4 from between the two clamping plates 7. Then the disassembly and assembly of the pipe jacking machine 1 can be carried out, which facilitates the disassembly and installation of the correction device by the staff.

[0028] Reference Figures 2-4Sliding rods 10 are slidably connected to both the left and right sides of the base plate 2. Positioning grooves are provided on both the left and right sides of the bottom side of the pipe jacking machine 1. The top end of the sliding rod 10 is inserted into the positioning groove. Second threaded rods 11 are rotatably connected to both the left and right sides of the base plate 2. The internal threads of the sliding rod 10 are connected to the outer wall of the second threaded rod 11. Second motors 12 are installed on both the left and right sides of the base plate 2. The bottom end of the second threaded rod 11 is fixedly connected to the drive end of the second motor 12. The second motor 12 drives the second threaded rod 11 to rotate. Because the outer wall of the sliding rod 10 has a matching limiting groove inside the base plate 2, the second threaded rod 11 drives the sliding rod 10 to move up and down, thus driving the sliding rod 10. The sliding rod 10 is inserted into or detached from the bottom side of the pipe jacking machine 1. When it is necessary to adjust the angle of the right side of the pipe jacking machine 1, the second motor 12 on the left side is activated to drive the second threaded rod 11 to rotate, so that the sliding rod 10 is inserted into the bottom side of the pipe jacking machine 1, thereby fixing the left side of the pipe jacking machine 1. Then, the two first motors 5 on the right side are simultaneously driven to drive the two first threaded rods 6 on the right side to rotate synchronously, so that the two clamping plates 7 on the right side slide synchronously, thereby pushing the right side of the pipe jacking machine 1 to rotate around the left side of the pipe jacking machine 1, thereby adjusting the angle of the right side of the pipe jacking machine 1. The reverse is also true, so that the device can not only correct the horizontal deviation of the pipe jacking machine 1, but also correct the angle, thereby improving the correction range of the correction device and improving its functionality. At the same time, when the pipe jacking machine 1 needs to be adjusted in angle after horizontal displacement, the first motor 5 on the left side can be activated to clamp the left side of the pipe jacking machine 1 with the two clamping plates 7 on the left side, thereby fixing the left side of the pipe jacking machine 1. Then, the first motor 5 on the right side is activated to repeat the above process, thereby adjusting the angle of the right side of the pipe jacking machine 1. The presence of the rubber pad 8 creates a certain space between the clamping plate 7 and the pipe jacking machine 1, thus meeting the needs of angle adjustment. Grooves and arc-shaped slots are provided on both the left and right sides of the top side of the base plate 2. Multiple rollers 9 are rotatably connected inside the grooves and arc-shaped slots, allowing the pipe jacking machine 1 to move or rotate more smoothly. The bottom side of the clamping plate 7 is threadedly connected to the outer wall of the first threaded rod 6. The front and rear sides of the base plate 2 are equipped with first motors 5. The end of the first threaded rod 6 is fixedly connected to the drive end of the first motor 5. Each first motor 5 drives the corresponding first threaded rod 6, thereby adjusting the position of the clamping plate 7 so that the clamping plate 7 can push the pipe jacking machine 1 to move horizontally. For example, when it is necessary to push the pipe jacking machine 1 forward, the two first motors 5 on the front side drive the clamping plate 7 on the front side to move forward at the same time, while the two first motors 5 on the rear side drive the clamping plate 7 on the rear side to move forward at the same time, thereby pushing the pipe jacking machine 1 forward. The outer wall of the first threaded rod 6 is coated with a protective coating to cope with the harsh underground environment and prevent it from affecting the transmission. The device is equipped with a corresponding control system to control the structure in the device, such as the first motor 5 and the second motor 12, to coordinate their operation.

[0029] Working principle: First, place the pipe jacking machine 1 on the base plate 2, ensuring that the positioning groove on its bottom side is aligned with the sliding rod 10. Then, place the metal rod 4 between the front and rear clamping plates 7. Next, use a screwdriver or other tools to screw the bolts into the clamping plates 7 and the metal rod 4, thus fixing the metal rod 4 to the front and rear clamping plates 7. Then, insert the insert plate 15 into the slot so that the insert block 14 is inserted into the strip groove. During this process, the limiting block 17 will engage in the limiting groove, thus connecting the top side of the clamping plate 7 to the metal rod 4. When it is necessary to adjust the horizontal position of the pipe jacking machine 1, such as when it is necessary to push the pipe jacking machine 1 forward, the two front first motors 5 simultaneously drive the front clamping plates. 7 moves forward, while the two first motors 5 on the rear side simultaneously drive the rear clamping plate 7 to move forward, thereby pushing the pipe jacking machine 1 forward. When it is necessary to adjust the angle of the right side of the pipe jacking machine 1, the second motor 12 on the left side is started to drive the second threaded rod 11 to rotate, so that the slide rod 10 is inserted into the bottom side of the pipe jacking machine 1, thereby fixing the left side of the pipe jacking machine 1. Then, the two first motors 5 on the right side are simultaneously driven to drive the two first threaded rods 6 on the right side to rotate synchronously, so that the two clamping plates 7 on the right side slide synchronously, thereby pushing the right side of the pipe jacking machine 1 to rotate around the left side of the pipe jacking machine 1, thereby adjusting the angle of the right side of the pipe jacking machine 1, and vice versa.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
