Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal construction, specifically a long-distance pipe jacking main jacking fixing and correction device. Background Technology
[0002] In long-distance pipe jacking construction, the commonly used main jacking device typically includes four 100-ton hydraulic cylinders, with a total thrust of up to 4,000 kilonewtons. These cylinders are assembled in a cylinder support and can operate individually or in conjunction to adapt to different construction needs. However, existing main jacking devices are relatively poor in terms of fixation, especially under complex geological conditions, and are prone to displacement.
[0003] Taking the pipe jacking construction of water intake pipelines from control wells as an example, a control well is a type of sluice gate used to connect water diversion culverts and pipelines to a reservoir to control and regulate water level and flow. Between the control well and the reservoir, there are typically high-water-level and low-water-level water intake pipelines. Pipe jacking construction of the water intake pipeline requires long-distance construction from the control well to the reservoir area, necessitating the use of long-distance main jacking devices. However, due to factors such as long construction distances and complex geological conditions, the issue of securing the main jacking device becomes particularly prominent.
[0004] The shortcomings of existing main jacking devices in terms of fixation are mainly reflected in the following aspects: First, the fixing method is singular and lacks adaptability; second, the fixing effect is poor, and displacement is prone to occur; third, there is a lack of effective correction mechanism, and once displacement occurs, it is difficult to adjust in time. These problems seriously affect the stability and efficiency of long-distance pipe jacking construction. Utility Model Content
[0005] The present invention aims to overcome the defects of the prior art and provide a long-distance pipe jacking main jacking fixing and correction device to solve the problem of pipe deviation during the main jacking process of long-distance pipe jacking.
[0006] To solve the above-mentioned technical problems, this utility model is implemented as follows:
[0007] A long-distance pipe jacking main jacking fixing and correction device is characterized in that: it includes a fixing base, four hydraulic cylinders are fixedly connected to the top of the fixing base, and a fixing component is provided at the bottom of the fixing base;
[0008] The fixed components include fixed legs fixedly connected to the bottom of the fixed base, a movable opening at the bottom of the fixed legs, a first screw connected to the top of the movable opening, a drive cylinder connected to the outside of the first screw, a support leg fixedly connected to the bottom of the drive cylinder, a support fixedly connected to the bottom of the support leg, an extension plate fixedly connected to the outside of the support, through openings on both sides of the top of the extension plate, a pin in the through opening, a driven bevel gear fixedly connected to the outside of the first screw, a driving bevel gear connected to the driven bevel gear, a drive shaft connected to the driving bevel gear, and a positioning component for improving the stability of the fixed base. The first screw is rotatably connected to the top of the movable opening, the drive cylinder is screwed to the first screw, the driving bevel gear and the driven bevel gear mesh, and the pin is inserted into the through opening.
[0009] The aforementioned long-distance pipe jacking main jacking fixing and correction device is characterized in that it further includes a positioning component, which includes a movable opening at the top of the pin, through openings on both sides of the movable opening, an insert plate disposed in the through opening, a vertical plate fixedly connected to the top of the insert plate, a first inclined block fixedly connected to the top of the vertical plate, a second inclined block cooperating with the first inclined block, a second screw connected to the top of the second inclined block, a circular plate fixedly connected to the inner wall of the movable opening, a torsion plate fixedly connected to the top of the second screw, grooves on both sides of the movable opening, a guide rod fixedly connected to one side of the first inclined block, and a spring sleeved on the outside of the guide rod. The insert plate is slidably connected to the through opening, the second screw is screwed to the circular plate, the second screw is rotatably connected to the second inclined block, and the guide rod is slidably connected to the groove.
[0010] The aforementioned long-distance pipe jacking main jacking fixing and correction device is characterized in that: anti-rotation grooves are respectively opened on both sides of the moving port, and anti-rotation blocks are respectively fixedly connected to both sides of the driving cylinder, and the anti-rotation blocks are slidably connected to the anti-rotation grooves.
[0011] The aforementioned long-distance pipe jacking main jacking fixing and correction device is characterized in that: a fixed plate is fixedly connected to one end of the drive shaft, and a connecting handle is fixedly connected to one side of the fixed plate.

Because the device possesses excellent stability and self-adjusting capabilities, it significantly reduces adjustment time caused by unstable fixing or misalignment during construction, thereby improving construction efficiency.
[0017] The stable fixing effect ensures that the pipe jacking can advance along the predetermined trajectory during construction, reducing the occurrence of offset and deviation, thereby improving construction quality. Because construction quality is guaranteed, rework caused by offset or deviation can be greatly reduced, further lowering construction costs and thus reducing labor costs.
[0018] The device's multi-level fixing structure and adjustable height design allow it to adapt to various geological conditions, such as soft soil, hard soil, and rock. Whether it's for controlled-well water intake pipeline jacking construction or other types of long-distance pipe jacking construction, this device can provide stable fixing and correction effects.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.
[0027] like Figure 1-5As shown: A long-distance pipe jacking main jacking fixing and correction device includes a fixed base 1, four hydraulic cylinders 11 fixedly connected to the top of the fixed base 1, and a fixing component at the bottom of the fixed base 1. The fixing component includes fixed legs 21 fixedly connected to the four sides of the bottom of the fixed base 1, a movable opening 22 at the bottom of the fixed legs 21, a first screw 23 connected to the top of the movable opening 22, a drive cylinder 24 connected to the outside of the first screw 23, a support leg 25 fixedly connected to the bottom of the drive cylinder 24, a support 26 fixedly connected to the bottom of the support leg 25, an extension plate 27 fixedly connected to the outside of the support 26, through openings 28 on both sides of the top of the extension plate 27, a pin 29 in the through opening 28, a driven bevel gear 30 fixedly connected to the outside of the first screw 23, a driving bevel gear 31 connected to the driven bevel gear 30, and a connecting pin to the driving bevel gear 31. The device includes a drive shaft 32 and a positioning component for improving the stability of the fixed base 1. The first screw 23 is rotatably connected to the top of the moving port 22. The drive cylinder 24 is screwed to the first screw 23. The active bevel gear 31 and the driven bevel gear 30 mesh. The pin 29 is inserted into the through port 28. The fixed base 1 can be stably supported and fixed by the support 26. At the same time, the rotation of the drive shaft 32 can cause the active bevel gear 31 to drive the driven bevel gear 30 to rotate, thereby controlling the rotation of the first screw 23. This can control the vertical position of the support leg 25 and the support 26, which can be adjusted according to the unevenness of the ground to ensure that the device is placed horizontally and stably supported. The pin 29 can be inserted into the soil to further improve the fixing performance of the fixed base 1 and effectively prevent the fixed base 1 from moving. The top of the pin is provided with a fixing cover 91, which is screwed to the pin. The movable port 22 has anti-rotation grooves 61 on both sides. Anti-rotation blocks 62 are fixedly connected to both sides of the drive cylinder 24. The anti-rotation blocks 62 are slidably connected to the anti-rotation grooves 61. The anti-rotation blocks 62 can move vertically synchronously with the drive cylinder 24, which can prevent the drive cylinder 24 from rotating synchronously with the first screw 23 and ensure the vertical stable movement of the drive cylinder 24. The anti-rotation blocks 62 are I-shaped and the anti-rotation grooves 61 are T-shaped, which can restrict the movement of the anti-rotation blocks 62 and prevent the anti-rotation blocks 62 from detaching laterally from the anti-rotation grooves 61. One end of the drive shaft 32 is fixedly connected to a fixed disk 71. A connecting handle 72 is fixedly connected to one side of the fixed disk 71. The connecting handle 72 can easily drive the fixed disk 71 and the drive shaft 32 to rotate, which in turn can easily drive the active bevel gear 31 to rotate, and can easily adjust the vertical position of the support 26.
[0028] The positioning component includes a movable opening 41 at the top of the pin, through openings 42 on both sides of the movable opening, an insert plate 43 inside the through opening, a vertical plate 44 fixedly connected to the top of the insert plate, a first inclined block 45 fixedly connected to the top of the vertical plate, a second inclined block 46 cooperating with the first inclined block, a second screw 47 connected to the top of the second inclined block, a circular plate 48 fixedly connected to the inner wall of the movable opening, a torsion plate 49 fixedly connected to the top of the second screw, grooves 50 on both sides of the movable opening, a guide rod 51 fixedly connected to one side of the first inclined block, and a spring 52 sleeved on the outside of the guide rod. The insert plate is slidably connected to the through opening, the second screw is screwed to the circular plate, the second screw is rotatably connected to the second inclined block, and the guide rod is slidably connected to the groove. A horizontal plate 81 is fixedly connected to both sides of the second inclined block, and a fixing rod 82 is fixedly connected to the top of the horizontal plate. The fixing rod passes through the circular plate and is slidably connected to the circular plate.
[0029] Working principle: During operation, rotating the connecting handle 72 causes the fixed plate 71 to rotate, which in turn drives the drive shaft 32. The drive shaft 32 then drives the active bevel gear 31, which in turn drives the driven bevel gear 30. The driven bevel gear 30 then drives the first screw 23, which in turn moves the drive cylinder 24 vertically. This movement of the drive cylinder 24 moves the support legs 25 and the support 26, allowing for adjustment based on ground unevenness to ensure the device is placed horizontally and stably supported. At this time, the support 26 and the extension plate 27 are in contact with the ground. Then, press the pin 29 into the soil, and then rotate the fixing cover 91 to unscrew it from the pin 29. Next, rotate the torsion plate 49, which will drive the second screw 47 to rotate. The rotation of the second screw 47 will cause the second inclined block 46 to move downwards. The downward movement of the second inclined block 46 will compress the first inclined block 45, causing it to move laterally. The movement of the first inclined block 45 will deform the spring 52, simultaneously causing the insertion plate 43 to be inserted laterally into the soil, increasing the contact area and further improving the fixing effect on the fixing seat 1. Then, screw the fixing cover 91 back onto the top of the pin 29. This completes the working process of the entire device. Furthermore, any content not described in detail in this specification belongs to existing technology known to those skilled in the art.
[0030] Four hydraulic cylinders are fixedly connected to the top of the mounting base. These four cylinders provide the thrust required for jacking, ensuring that the jacking pipe can advance stably.
[0031] The base has a complex set of fixing components, including fixing legs, a moving port, a first screw, a drive cylinder, support legs, a support, and an extension plate. This multi-level design can distribute the fixing force and improve the overall stability.
[0032] The drive shaft rotates the driving and driven bevel gears, which in turn controls the rotation of the first screw, thus adjusting the vertical position of the drive cylinder, outriggers, and support. This design allows for adjustment based on the unevenness of the ground, ensuring the device is placed horizontally and stably supported.
[0033] The extension plate has pins in the openings on both sides of the top, which can be inserted into the soil to further enhance the fixing effect of the fixing seat.
[0034] The positioning components include a movable opening, a through opening, an insert plate, a vertical plate, a first inclined block, a second inclined block, and a second screw. Rotating the torsion plate drives the second screw to rotate, thereby controlling the lateral movement of the insert plate and allowing it to insert into the soil. This design increases the contact area, further improving the fixing effect on the mounting base.
[0035] The design of the first and second inclined blocks allows the insert plate to adaptively adjust its angle and depth when inserted into the soil, ensuring the stability and reliability of the fixing effect.
[0036] Anti-rotation grooves are provided on both sides of the moving port, and anti-rotation blocks are fixedly connected to both sides of the drive cylinder. The anti-rotation blocks are slidably connected to the anti-rotation grooves, which can prevent the drive cylinder from rotating synchronously with the first screw and ensure the vertical stable movement of the drive cylinder.
[0037] Through the above design, this long-distance pipe jacking main jacking fixing and correction device effectively solves the technical problems pointed out in the background art. Its multi-level fixing structure, adjustable height design, soil fixing method, and enhanced fixing effect of positioning components, together improve the stability and efficiency of pipe jacking construction and reduce the risk of pipe deviation.
[0038] The above are merely embodiments provided in this application and are not intended to limit this application. Although this application has been described in detail with reference to the 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. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
