Description

Technical Field

[0001] This utility model relates to the field of pipe jacking machine technology, specifically to a guiding micro pipe jacking device suitable for confined spaces. Background Technology

[0002] With the acceleration of urbanization and the advancement of integrated urban-rural development, infrastructure construction in rural and urban areas has received increasing attention. As an advanced trenchless construction method, micro-pipe jacking technology has been widely used in urban infrastructure construction both domestically and internationally due to its advantages such as minimal surface disturbance, high construction efficiency, and low environmental impact.

[0003] During construction, the working shaft is excavated first, and then the guide rail is installed in the working shaft. After the installation is completed, the pipe jacking machine is placed into the working shaft and connected to the guide rail. Then, rubber sealing rings or water-stop rings are installed at the opening of the working shaft to prevent mud or groundwater leakage. Then, jacks are used to start trial jacking to check the attitude of the pipe jacking machine. After the check is completed, the construction is finally carried out.

[0004] In existing technology, guide rails are installed in the working shaft, and then the pipe jacking machine is installed on the guide rails. However, the bottom of the working shaft is uneven. Before installing the guide rails, the working shaft needs to be leveled to avoid deviations in the posture of the pipe jacking machine. Then, a trial pipe jacking stage is carried out to test the posture of the pipe jacking machine and the geological characteristics of the area to be jacked. If the area to be jacked is not suitable for operation, the construction area will be changed, or the pipe jacking machine will be raised or lowered. However, when the pipe jacking machine is raised or lowered, the horizontal posture needs to be readjusted. Repeated adjustments waste time and reduce work efficiency. Utility Model Content

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to the attached diagram. Figures 1-5 As shown, the guide micro-jacking device for confined spaces in this embodiment of the present invention includes a jacking machine body 1, a fixed base 12, and a lifting base 2; the jacking machine body 1 is placed on the fixed base 12, and the fixed base 12 is hinged to the lifting base 2; a first vertical plate 3 and a second vertical plate 8 are fixedly connected to the lifting base 2; a lifting screw 7 is rotatably connected to the side wall of the first vertical plate 3; the end of the lifting screw 7 away from the first vertical plate 3 is rotatably connected to the second vertical plate 8; a sliding plate is fixedly connected to the lifting base 2. Rail 5; a slider 6 is slidably connected to the rail 5; a lifting screw 7 passes through the slider 6 and is threadedly connected to the slider 6; a hinge block 11 is fixedly connected to the bottom of the fixed base 12; multiple sets of hinge blocks 11 are provided; hinge rod 1 9 and hinge rod 2 10 are rotatably connected to the side wall of hinge block 11; the end of hinge rod 1 9 away from hinge block 11 is hinged to the vertical plate 2 8; the end of hinge rod 2 10 away from hinge block 11 is hinged to the vertical plate 3; hinge rod 1 9 and hinge rod 2 10 are rotatably connected.

[0027] During operation, the bottom of the working shaft is first leveled, and then the pipe jacking machine body 1 is placed on the fixed base 12. The fixed base 12 is then used to secure the pipe jacking machine body 1. After securing, the fixed base 12 and the lifting base 2 are placed inside the working shaft. Once placed, pipe jacking testing can begin. During testing, if the tested area is found to be unsuitable for pipe jacking operations, the height of the pipe jacking machine body 1 needs to be adjusted. During adjustment, the lifting screw 7 on the lifting base 2 is driven to rotate. When the lifting screw 7 rotates, it drives the threaded slider 6 to move on the slide rail 5. The movement of the slider 6 will drive... When hinge rod 2 10 rises, it works in conjunction with hinge rod 1 9 to lift the fixed base 12, thereby enabling the lifting and lowering of the pipe jacking machine body 1. The fixed base 12 facilitates the clamping and fixing of the pipe jacking machine body 1. The lifting base 2 allows for convenient pipe jacking operations at different heights. Furthermore, the slider 6, hinge rod 1 9, and hinge rod 2 10 in the lifting base 2 prevent the fixed base 12 from shaking when it is lifted. The coordinated connection between hinge rod 1 9 and hinge rod 2 10 ensures smooth lifting and lowering of the fixed base 12, preventing any deviation.

[0028] like Figure 4As shown, a rotating shaft 13 is rotatably connected inside the fixed base 12; a drive gear 15 is fixedly connected to the rotating shaft 13; a middle plate 16 is fixedly connected to the side wall of the fixed base 12; a double-acting lead screw 17 is rotatably connected to both side walls of the middle plate 16; a transmission gear 18 is fixedly connected to the double-acting lead screw 17; the transmission gear 18 meshes with the drive gear 15; a moving plate 19 is threadedly connected to the double-acting lead screw 17; a clamping plate 20 is fixedly connected to the moving plate 19; a shell plate 21 is movably connected to the top of the fixed base 12; the clamping plate 20 penetrates the shell plate 21.

[0029] During operation, after placing the pipe jacking machine body 1 on the fixed base 12, the drive shaft 13 is rotated, which in turn drives the drive gear 15 to rotate. When the drive gear 15 rotates, it drives the transmission gear 18 to rotate, which in turn drives the double-acting screw 17 to rotate. This causes the moving plate 19 on the double-acting screw 17 to move. When the moving plate 19 moves, it causes the clamping plate 20 to move closer to the pipe jacking machine body 1, thereby fixing the pipe jacking machine body 1. The fixed base 12 can clamp the pipe jacking machine body 1. At the same time, the double-acting screw 17 can be adapted to pipe jacking machine bodies 1 of different sizes, thereby improving the adaptability of the fixed base 12 and making it suitable for operations in various narrow areas.

[0030] like Figure 4 As shown, a limiting rod 23 is fixedly connected to the side wall of the fixed base 12; one end of the limiting rod 23 away from the fixed base 12 is fixedly connected to the middle plate 16; the movable plate 19 is set through the limiting rod 23;

[0031] During operation, the movable plate 19 is limited by the limiting rods 23 on both sides, which prevents the movable plate 19 from deviating during movement.

[0032] like Figure 4 As shown, a fixed motor 14 is fixedly connected to the bottom of the fixed base 12; the rotating shaft 13 is driven by the fixed motor 14.

[0033] During operation, the fixed top drive shaft 13 rotates, thereby driving the drive gear 15 to rotate, thus clamping the pipe jacking machine body 1. At the same time, the double-acting screw 17 is a trapezoidal screw, which can convert rotary motion into linear motion and prevent shaking and crawling during movement.

[0034] like Figure 2 As shown, a sliding groove 22 is provided on the shell plate 21; the clamping plate 20 is disposed in the sliding groove 22;

[0035] During operation, the clamping plate 20 is set through the slide groove 22, thereby realizing movement and clamping of the pipe jacking machine body 1.

[0036] like Figure 2As shown, a lifting motor 4 is fixedly connected to the side wall of the upright plate 3; the lifting screw 7 is driven by the lifting motor 4.

[0037] During operation, the lifting motor 4 drives the lifting screw 7 to rotate, thereby driving the slider 6 to move and realize the raising and lowering of the fixed base 12.

[0038] like Figure 4 As shown, both the transmission gear 18 and the drive gear 15 are crown gears;

[0039] During operation, the crown gear can achieve better meshing.

[0040] The working principle of this utility model is as follows: When operation is required, the bottom of the working well is first leveled, and then the pipe jacking machine body 1 is placed on the fixed base 12. The fixed base 12 is then used to fix the pipe jacking machine body 1. After fixing, the fixed base 12 and the lifting base 2 are placed inside the working well. After placement, pipe jacking testing can begin. During the testing process, if it is found that the tested area is unsuitable for pipe jacking operations, the height of the pipe jacking machine body 1 needs to be adjusted. During adjustment, the lifting screw 7 on the lifting base 2 is driven to rotate. When the lifting screw 7 rotates, it drives the threaded slider 6 to move on the slide rail 5. When the lifting base 2 is raised, it will drive the second hinge rod 10 to rise. During the raising process, it will work with the first hinge rod 9 to lift the fixed base 12, thereby realizing the lifting and lowering operation of the pipe jacking machine body 1. The fixed base 12 can be used to easily clamp and fix the pipe jacking machine body 1. The lifting base 2 can be used to easily carry out pipe jacking operations in areas of different heights. At the same time, the slider 6, the first hinge rod 9 and the second hinge rod 10 in the lifting base 2 can prevent the fixed base 12 from shaking when it is lifted. The cooperation between the first hinge rod 9 and the second hinge rod 10 can smoothly realize the lifting and lowering of the fixed base 12 and avoid deviation.

[0041] After the pipe jacking machine body 1 is placed on the fixed base 12, the drive shaft 13 is rotated, which in turn drives the drive gear 15 to rotate. When the drive gear 15 rotates, it drives the transmission gear 18 to rotate. When the transmission gear 18 rotates, it drives the double-acting screw 17 to rotate, which in turn drives the moving plate 19 on the double-acting screw 17 to move. When the moving plate 19 moves, it drives the clamping plate 20 to move closer to the pipe jacking machine body 1, thereby fixing the pipe jacking machine body 1. The fixed base 12 can clamp the pipe jacking machine body 1. At the same time, the double-acting screw 17 can be adapted to pipe jacking machine bodies 1 of different sizes, thereby improving the adaptability of the fixed base 12 and making it suitable for operations in various narrow areas.

[0042] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
