Description

Technical Field

[0001] This utility model relates to the field of pipe jacking construction, specifically a pipe jacking device for underground pipeline construction. Background Technology

[0002] Pipe jacking is a trenchless construction method, a technology for laying pipelines without excavation or with minimal excavation. In pipe jacking, the jacking force generated by the jacking equipment in the working pit overcomes the friction between the pipeline and the surrounding soil, pushing the pipeline into the soil at the designed slope, and then removing the excavated soil. After one section of the pipe is pushed into the soil, the second section is pushed in to continue jacking. The principle is to use the thrust of the main jacking cylinder and the pipeline and intermediate sections to push the tool pipe or tunneling machine from the working pit through the soil layer to the receiving pit and lift it out. The pipeline follows the tool pipe or tunneling machine and is buried between the two pits.

[0003] For example, the underground pipeline construction pipe jacking device described in (authorization announcement number CN222633978U) includes a base, a movable guide rail on the base, a clamping sliding seat and a pipe jacking sliding seat on the movable guide rail, a pipe jacking slide rail on the pipe jacking slide rail, a pipe jacking seat on the pipe jacking seat, a support clamping plate on the pipe jacking plate, a pushing hydraulic cylinder on the support clamping plate, a pressure plate at the top of the pushing hydraulic cylinder, a clamping slide rail on the clamping sliding seat, a positioning seat on the clamping slide rail, and a fixing component at the top of the positioning seat.

[0004] The aforementioned device automatically aligns with the top pressure plate while fixing the pipeline by moving guide rails, jacking slide rails, and clamping slide rails, simplifying the operation for workers and facilitating pipe jacking construction. However, the aforementioned device does not have a device to detect and discharge water or sludge at the bottom of the device, which means that when there is water or sludge at the bottom of the device, it is inconvenient to manually control the sludge pump to discharge it.

A lighting lamp 15 is fixedly connected to the front side of the upper end of the cylinder frame 13, and a monitoring camera 16 is fixedly connected to the front side of the upper end of the cylinder frame 13. There are four sets of hydraulic cylinders 12.

[0026] The support tube assembly 2 has a slide 21 located at the front end of the cylinder frame 13, a slide groove 22 located in the middle of the slide 21, and a motor 23 fixedly connected to the right end of the slide 21. After the motor 23 is started, it can drive the positive and negative threaded rods 24 to rotate. When the positive and negative threaded rods 24 rotate, they can drive the movable frame 25 and its upper components to move left and right to a designated position. The left and right ends of the positive and negative threaded rods 24 are rotatably connected to the slide 21 through the slide grooves 22. The lower end of the movable frame 25 is slidably connected to the slide 21 through the slide grooves 22. The lower end of the movable frame 25 is threadedly connected to the positive and negative threaded rods 24 through the threaded grooves 26. The threaded grooves 26 are located at the lower end of the movable frame 25. The upper and lower ends of the first roller 27 are rotatably connected to the side of the movable frame 25.

[0027] The base assembly 3 has a base 31 with its upper rear side fixedly connected to the support plate 11 and the cylinder frame 13, and its upper front side fixedly connected to the slide 21.

[0028] This utility model provides an improved pipe jacking device for underground pipeline construction, the working principle of which is as follows:

[0029] First, when using this device, place it in the work area and then connect it to an external power source to provide the necessary electrical energy for its operation.

[0030] Secondly, when this device is needed, the pipe to be jacked can be placed on the upper end of the second roller 35. Then, the lighting lamp 15 and the monitoring camera 16 can be activated by the display controller 33. After the lighting lamp 15 is activated, it can illuminate the second roller 35 and the environment above it for easy monitoring. After the monitoring camera 16 is activated, it can monitor the second roller 35 and the environment above it, monitor the position of the pipe, and send the monitored data to the display controller 33 for processing and display via a data cable. After the display controller 33 receives the image data, it can control the motor 23 to start according to the position of the pipe. After the motor 23 starts, it can drive the positive and negative threaded rod 24 to rotate. When the positive and negative threaded rod 24 rotates, it can drive the moving frame 25 and its upper components to move towards the center, so that the first roller 27 contacts the pipe for clamping and prevents the pipe from falling off. When the device shifts due to ground subsidence, the telescopic net 36 can be extended or retracted to prevent dust from entering as the moving frame 25 moves left or right. Then, the hydraulic cylinder 12 is activated, which can move the top pressure plate 14 forward to contact the pipe and carry out the pipe jacking work. When the pipe is pushed, the first roller 27 and the second roller 35 can rotate synchronously to ensure stable pipe transport. When the device shifts due to ground subsidence, the tilt sensor 32 can be activated. When the tilt sensor 32 tilts, its internal mass block will be subjected to unbalanced force to produce displacement or deformation, and output an electrical signal. The analog signal output by its internal accelerometer is filtered, temperature compensated and digitally converted (such as by DSP processing) to eliminate noise interference and correct errors. Finally, the digital tilt angle data is output and sent to the display controller 33 for processing and display to prompt the workers to stop the pipe jacking work.
