Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, and in particular to a positioning mechanism for laying new pipelines in quicksand geology. Background Technology

[0002] Pipeline laying positioning mechanisms are structural components used to support pipelines, providing necessary support and fixation to ensure that the pipeline can be laid in a predetermined position and angle. They are widely used in many fields such as water supply, drainage, gas, and oil. Shifting sand geology is characterized by high fluidity and low bearing capacity, which brings many challenges to pipeline laying.

[0003] Existing positioning mechanisms for pipeline laying have a relatively simple structure and use a fixed structure, which cannot adapt to pipelines of different diameters. When laying pipelines in quicksand geological conditions, the stability is insufficient, and there is a risk of pipeline deviation and misalignment. It is difficult to accurately position and adjust in time, which increases the construction difficulty and error and affects the accuracy of pipeline laying.

[0004] Therefore, in view of the problems of low adaptability, insufficient stability and low pipeline laying accuracy of the existing pipeline laying positioning mechanism, a pipeline laying positioning mechanism with high versatility and high laying accuracy can be designed. Utility Model Content

[0006] The technical solution of this utility model is as follows: a positioning mechanism for laying new pipelines in quicksand geology, including a base; it also includes a limiting plate and a clamping plate. Four sets of trough-shaped rollers are fixedly connected to the upper end of the base. A jacking pipe is provided at the upper end of the trough-shaped rollers. An adjustment cavity is opened on the rear side of the upper end of the base. A bidirectional threaded rod is rotatably connected inside the adjustment cavity. The two ends of the bidirectional threaded rod are symmetrically threaded to the limiting plate. A pipe jacking machine is fixedly connected to the front side of the upper end of the base. An extrusion seat is fixedly connected to the output end of the pipe jacking machine. An installation seat is fixedly connected to the rear end of the extrusion seat. A laser positioning instrument is fixedly connected to the end of the installation seat away from the pipe jacking machine. A clamping plate is provided inside the jacking pipe on the rear side of the installation seat. A controller is fixedly connected to the front end of the extrusion seat. A lifting cylinder is fixedly connected to the lower end of the trough-shaped rollers.

[0007] Preferably, the mechanism is placed at the starting point of the pipeline laying. The height of the lifting cylinder is adjusted according to the quicksand geology. The jacking pipe is placed on the trough roller. The three clamping plates move, and the inner wall of the jacking pipe is squeezed to complete the connection with the extrusion seat. The bidirectional threaded rod is rotated to drive the limiting plate to make relative movement and move the same distance to clamp and fix the jacking pipe in the center. The jacking machine drives the extrusion seat to push the jacking pipe to lay the pipeline. The laser positioning instrument monitors the pipeline position information in real time. The lifting cylinder is adjusted to different heights to correct the deviation of the jacking pipe and guide the pipeline to be laid along the predetermined route.

[0008] Preferably, an adjustment motor is fixedly connected to the rear side of the left end of the base. The output shaft of the adjustment motor is fixedly connected to one end of the bidirectional threaded rod, and the adjustment motor is electrically connected to the controller.

[0009] Preferably, the end of the limiting plate near the top pull tube is rotatably connected to two sets of rollers via a connecting frame. Each set of rollers has two rollers arranged symmetrically above and below, and the rollers are made of rubber.

[0010] Preferably, an electric push rod is fixedly connected to the surface of the mounting base. Three electric push rods are arranged in a circular array. Both the pipe jacking machine and the electric push rods are electrically connected to the controller.

[0011] Preferably, the output end of the electric push rod is fixedly connected to the corresponding clamping plate, and a rubber pad is fixedly connected to the end of the clamping plate near the top pull tube. The surface of the rubber pad is uniformly provided with anti-slip protrusions.

[0012] Preferably, four lifting cylinders are provided. Both the laser positioning device and the lifting cylinders are electrically connected to the controller, and the lower end of the lifting cylinder is fixedly connected to a support leg.

[0013] Preferably, a water pump is fixedly connected to the upper end of the base on the left side of the pipe jacking machine, and the water pump's inlet and outlet are respectively connected to an inlet pipe and a drain pipe.

[0014] The beneficial effects of this utility model are:

[0015] This novel positioning mechanism for pipeline laying in shifting sand geology utilizes limiting plates and clamping plates to position the mechanism at the starting point of pipeline laying. The height of the lifting cylinder is adjusted according to the shifting sand geology to ensure horizontal and stable pipeline laying. The jacking pipe is placed on the trough-shaped rollers, and the three clamping plates move, squeezing the inner wall of the jacking pipe to complete the connection with the squeezing seat. It adapts to jacking pipes of different diameters. Rotating the bidirectional threaded rod drives the limiting plate to move relative to each other and move the same distance, clamping and fixing the jacking pipe in the center. This improves the versatility and flexibility of the mechanism, and enhances the straightness and accuracy of pipeline laying. The jacking machine drives the squeezing seat to push the jacking pipe for pipeline laying. The transportation process is safe and stable, and the construction laying efficiency is high. A laser positioning instrument monitors the pipeline position information in real time, and adjusting the height of the lifting cylinder corrects the deviation of the jacking pipe, guiding the pipeline along the predetermined route. Control and adjustment are convenient, improving the accuracy and efficiency of pipeline laying. Attached Figure Description

A lifting air valve is fixedly connected to the lower end of the trough-shaped rollers 2. When using cylinder 13, the mechanism is placed at the starting point of pipeline laying. The height of the lifting cylinder 13 is adjusted according to the quicksand geology to ensure the pipeline is laid horizontally and stably. The top-pulling pipe 3 is placed on the trough roller 2, and the three clamping plates 11 move to squeeze the inner wall of the top-pulling pipe 3 to complete the connection with the extrusion seat 8. It can adapt to top-pulling pipes 3 of different diameters. Rotating the bidirectional threaded rod 5 drives the limiting plate 6 to make relative movements and move the same distance to clamp and fix the top-pulling pipe 3 in the center, improving the versatility and flexibility of the mechanism and improving the straightness and accuracy of pipeline laying. The pipe jacking machine 7 drives the extrusion seat 8 to push the top-pulling pipe 3 to lay the pipeline. The conveying process is safe and stable, and the construction laying efficiency is high.

The control and adjustment are convenient, improving the laying accuracy and efficiency of the pipeline.

[0024] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, an adjusting motor 14 is fixedly connected to the rear side of the left end of the base 1. The output shaft of the adjusting motor 14 is fixedly connected to one end of the bidirectional threaded rod 5. The adjusting motor 14 is electrically connected to the controller 12. The controller 12 controls the adjusting motor 14 to drive the bidirectional threaded rod 5 to rotate. Two sets of rollers 15 are rotatably connected to the end near the top of the jacking tube 3 through the connecting frame. Each set of rollers 15 has two rollers arranged symmetrically on the top and bottom. The rollers 15 are made of rubber. The jacking tube 3 moves along the rollers 15, which reduces the friction between the limiting plate 6 and the jacking tube 3, making it easier to operate and adjust, and improving the convenience and efficiency of construction. An electric push rod 16 is fixedly connected to the surface of the mounting base 9. Three electric push rods 16 are arranged in a circular array.

The support leg 18 enhances the stability of the placement. The height and angle are adjusted in real time according to the changes in quicksand geology to ensure the stability of the mechanism. A water pump 19 is fixedly connected to the upper end of the base 1 on the left side of the pipe jacking machine 7. The inlet and outlet of the water pump 19 are connected to the inlet pipe 20 and the outlet pipe 21, respectively. The water pump 19 draws water from the quicksand geology through the inlet pipe 20 and discharges it through the outlet pipe 21 to lower the water level and enhance the stability of the foundation.

[0025] During operation, the mechanism is placed at the starting point of pipeline laying. The height of the lifting cylinder 13 is adjusted according to the quicksand geology to ensure the pipeline is laid horizontally and stably. The jacking pipe 3 is placed on the trough roller 2. Three electric push rods 16 drive the clamping plate 11 to move, and the inner wall of the jacking pipe 3 is squeezed to complete the connection with the extrusion seat 8. The adjusting motor 14 drives the bidirectional threaded rod 5 to rotate, which drives the limit plate 6 to move relative to it and move the same distance, clamping and fixing the jacking pipe 3 in the center. The jacking machine 7 drives the extrusion seat 8 to push the jacking pipe 3 to lay the pipeline. The conveying process is safe and stable, and the construction laying efficiency is high. The laser positioning instrument 10 monitors the pipeline position information in real time. The lifting cylinder 13 is adjusted to different heights to correct the deviation of the jacking pipe 3 and guide the pipeline to be laid along the predetermined route. The control and adjustment are convenient, improving the laying accuracy and efficiency of the pipeline.

[0026] Through the above steps, the clamping plate 11 squeezes the inner wall of the top-pull pipe 3 and completes the connection with the extrusion seat 8. The limiting plate 6 clamps and fixes the top-pull pipe 3 in the center, improving the versatility and flexibility of the mechanism, improving the straightness and accuracy of pipeline laying, and increasing the construction laying efficiency. This solves the problems of low adaptability, insufficient stability, and low pipeline laying accuracy of existing positioning mechanisms for pipeline laying.
