Description

Technical Field

[0001] This utility model relates to the field of slurry pipe jacking machine technology, and more specifically, to an anti-deviation device for a slurry balanced pipe jacking machine. Background Technology

[0002] A slurry pipe jacking machine is a type of underground pipeline laying equipment used for trenchless construction. It mainly uses slurry pressure to balance the ground pressure, enabling pipeline jacking operations over long distances and in complex geological conditions. It is widely used in municipal engineering, crossing highways, railways, rivers, and other scenarios, and features minimal surface disturbance and strong adaptability.

[0003] Currently, when using a slurry balance pipe jacking machine, it mainly relies on the main jacking cylinder assembly to propel the machine forward, with the pipeline following behind to form continuous jacking. During this process, due to the lack of corresponding limiting means for the pipeline, the pipe jacking machine and the pipeline are prone to deviation. Once the pipe jacking machine and the pipeline deviate, they will deviate from the predetermined forward trajectory, which not only reduces the working efficiency of the pipe jacking operation but also poses a significant safety hazard and reduces the practicality of the equipment.

[0004] In view of this, we propose an anti-deviation device for a slurry-balanced pipe jacking machine. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] An anti-deviation device for a slurry-balanced pipe jacking machine includes a base plate 1. An installation groove 6 is provided on the upper side of the base plate 1. Two sets of installation blocks 7 are movably arranged inside the installation groove 6. A fixing frame 9 is fixedly installed on the upper side of each of the two sets of installation blocks 7. An installation frame 2 is provided on the upper side of the fixing frame 9. A clamping block 3 is fixedly installed on the outer side of the installation frame 2. Multiple pressure sensors 4 for docking with the clamping blocks 3 are provided inside the installation frame 2. Indicator lights 5 for multiple docking pressure sensors 4 are fixedly installed on the outer side of the installation frame 2. Two sets of first hydraulic cylinders 8 are provided inside the installation groove 6. One end of each set of first hydraulic cylinders 8 is connected to the installation groove 6, and the other end of each first hydraulic cylinder 8 is connected to the installation block 7.

[0029] refer to Figure 1 , Figure 5In practical use, the first hydraulic cylinder 8 drives the mounting frame 2 and the clamping block 3 to move and clamp and limit the pipeline. At this time, the pressure sensor 4 can monitor the pressure. The main jacking cylinder pushes the pipeline to move and advance. When the pipeline deviates, it will cause the clamping block 3 to deform to a certain extent. Moreover, there are multiple sets of pressure sensors 4, so no matter which direction the pipeline deviates, the pressure sensor 4 will detect the pressure change and transmit the information to the controller in time, so that the controller can turn on the indicator light 5 in time to facilitate worker intervention.

[0030] Specifically, a movable block 10 is movably inserted into the inner side of the fixed frame 9. The movable block 10 movably passes through the fixed frame 9 and extends to the outside. The upper part of the movable block 10 located on the outside of the fixed frame 9 is fixedly connected to the mounting frame 2.

[0031] refer to Figure 3 The movable block 10 slides within the fixed frame 9, which facilitates the adjustment of the position of the mounting frame 2 while ensuring the strength of the mounting frame 2, thereby improving the clamping stability of the pipe.

[0032] Furthermore, two sets of second hydraulic cylinders 11 are provided inside the fixed frame 9. One end of each set of second hydraulic cylinders 11 is connected to the fixed frame 9, and the other end of the second hydraulic cylinders 11 is connected to the mounting frame 2.

[0033] refer to Figure 3 The second hydraulic cylinder 11 can be easily moved by turning on the external power supply, so as to facilitate the adjustment of the height of the mounting frame 2 and meet various usage needs. The pressure sensor 4, indicator light 5, first hydraulic cylinder 8 and second hydraulic cylinder 11 are all connected and controlled by an external power supply or controller, which is existing technology and will not be described in detail.

[0034] It is worth noting that multiple sets of mounting slots 12 are provided on the outer side of the clamping block 3, and multiple sets of rollers 13 are rotatably provided on the inner side of each set of mounting slots 12.

[0035] refer to Figure 4 When the pipe is pushed forward, the movement of the pipe causes the roller 13 to rotate in the mounting groove 12, which reduces the friction during pipe movement and makes the pipe movement smoother. At the same time, the roller 13 can also limit the pipe and prevent the pipe from deviating.

[0036] It is worth noting that limit blocks 14 are fixedly installed on both sides of the mounting block 7, and limit grooves 15 for docking with the limit blocks 14 are opened on both sides of the mounting groove 6. The limit blocks 14 slide within the limit grooves 15.

[0037] refer to Figure 3By limiting the engagement of the limiting block 14 and the limiting groove 15, the stability of the mounting block 7 can be ensured while the first hydraulic cylinder 8 pushes the mounting block 7 to move, thereby improving the stability of the fixing frame 9, the mounting frame 2 and the clamping block 3, and thus improving the clamping stability of the pipeline and ensuring the limiting effect of the pipeline.

[0038] In addition, multiple sets of screw holes are drilled through the upper side of the base plate 1.

[0039] refer to Figure 1 , Figure 5 Holes for connecting bolts are made on the guide rail inside the launching well. By screwing bolts into the bolt holes, the base plate 1 can be fixed on the guide rail, thereby ensuring the overall stability of the device.

[0040] Working principle: First, by activating the two sets of first hydraulic cylinders 8, the mounting block 7 and the fixing frame 9 are moved. When the fixing frame 9 moves, it drives the mounting frame 2 and the clamping block 3 to move. The clamping block 3 clamps and limits the pipeline. At the same time, the clamping block 3 clamps the pipeline and squeezes the pressure sensor 4. At this time, the pressure sensor 4 transmits the pressure information to the controller. At this time, the indicator light 5 is in the off state. If the pipeline deviates during the jacking process, the pressure of the clamping block 3 on the pressure sensor 4 will change. The pressure sensor 4 will transmit the pressure change information to the controller, and the controller will then control the indicator light 5 to turn red, so that the staff can take appropriate measures in time.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
