Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a pipe jacking machine for water conservancy projects. Background Art

[0002] During the construction of underground pipelines in water conservancy projects, it is usually necessary to excavate the ground for the placement of cement pipes. The actual amount of work is large, and the noise pollution caused cannot be ignored. Therefore, the industry began to introduce a pipe jacking machine to excavate the soil. It is not only flexible in operation, but also can be used for ultra-long distance construction and arbitrary curve radius construction. The distance after the pipeline is installed cannot be moved.

[0003] There is a pipe jacking machine with patent announcement number CN108625872A, which has bearings arranged between the front section, middle section, rear section and housing of the main shaft, and then a large gear connected to the pinion gear is arranged between the middle section bearing and the rear section bearing of the main shaft. When the driving mechanism outputs power, the small gear drives the large gear to rotate and reduce the speed and increase the torque. The large gear further drives the main shaft and the cutter disc to rotate synchronously. In this process, since bearings are arranged between the front section, middle section and rear section of the main shaft and the housing, and since support bearings are also arranged at the front and rear ends of the large gear for the main shaft power input, the main shaft and the cutter disc can maintain a high degree of concentricity when rotating, and neither the main shaft nor the cutter disc will swing away from the axis. The cutter disc rotates smoothly, with large torque and small deformation, which can effectively ensure the construction progress.

[0004] However, the structure is fixed internally, which makes it inconvenient to inspect and maintain, and has poor practicality. Utility Model Content

The front part of the inner side of the shell 1 is evenly connected to multiple groups of connecting frames 2, the inner side of each group of connecting frames 2 is respectively connected to the outer side of a group of constraint bearings 3, the outer wall of the corresponding position of the synchronous shaft 4 is connected to the inner wall of each group of constraint bearings 3, the front side of the synchronous shaft 4 is connected to the middle of the rear side of the cutter head 6, and the rear side of the synchronous shaft 4 is connected to the middle of the front side of the driven large gear 5. The upper and lower ends of the inner rear of the shell 1 are respectively connected to the outer end of a group of mounting frames 7, and the mounting frame 7 is detachably screwed with a fixing bolt 8. The inner side of the vertical moving frame 9 is vertically slidably connected to the outer side of the vertical slider 10. An adjusting mechanism is provided between 9 and the vertical slider 10, the rear side of the vertical slider 10 is connected to the front side of the driving mechanism 15, and the output end of the driving mechanism 15 is connected to the driving gear 16; the vertical moving frame 9 is inwardly installed in the upper and lower side mounting frames 7 inside the housing 1, and then the fixing bolts 8 are screwed into the mounting frame 7 through the vertical moving frame 9 for fixing. After that, the vertical slider 10 is adjusted by the adjusting mechanism to slide down in the vertical moving frame 9, thereby driving the driving mechanism 15 and the driving gear 16 to move down, so that the driving gear 16 is meshed with the driven large gear 5. During operation, the housing 1 is placed in the corresponding position. When the housing 1 is forced to move forward, the driving mechanism 15 runs, driving the driving gear 16 to rotate, and the driving gear 16 is meshed with the driven large gear 5. The driven large gear 5 drives the synchronous shaft 4, which rotates under the constraint of being fixedly connected by the connecting frame 2 through multiple sets of constraint bearings 3, so that the cutter head 6 rotates to tamp the soil.

[0026] The adjusting mechanism includes a threaded sleeve 11, a threaded rod 12, an intermediate plate 13 and a screw disk 14. The lower side of the interior of the vertical moving frame 9 is connected to the outer side of the intermediate plate 13. The threaded rod 12 passes through the middle of the intermediate plate 13 and is vertically rotated to be connected to the vertical moving frame 9. The bottom end of the threaded rod 12 is connected to the middle of the top of the screw disk 14. A threaded sleeve 11 is vertically provided inside the vertical slider 10. The inner wall of the threaded sleeve 11 is screwed to the outer wall of the threaded rod 12. By twisting the screw disk 14, the threaded rod 12 can be rotated under the constraint of the intermediate plate 13. The threaded rod 12 is screwed with the threaded sleeve 11 to drive the vertical slider 10 to slide down the inside of the vertical moving frame 9, driving the driving mechanism 15 and the driving gear 16 to move downward, and after being engaged in place, it is fixed by the threaded self-locking of the threaded rod 12 and the threaded sleeve 11.

[0028] It also includes a spring 18 and a top plate 19. The lower right end of the middle plate 13 inside the vertical moving frame 9 is connected to the rear side of the top plate 19 via the spring 18.

[0030] It also includes a threaded groove 23, a mounting screw 24 and a lifting ring 25. Multiple groups of threaded grooves 23 are provided at the top of the shell 1. The inner wall of the threaded groove 23 and the outer wall of the mounting screw 24 are detachably screwed together, and the top of the mounting screw 24 is connected to the middle of the bottom end of the lifting ring 25; after the mounting screw 24 is screwed into the threaded groove 23, it can be lifted to the outside through the lifting ring 25, which facilitates the overall movement and improves convenience.

[0031] In summary, when a pipe jacking machine for a water conservancy project is in use, the vertical moving frame 9 can be installed inwardly in the upper and lower side mounting frames 7 inside the shell 1 by holding the handle 17, and then the fixing bolts 8 are passed through the vertical moving frame 9 and screwed into the mounting frame 7 for fixing. By holding the pull tab 22, the sliding rod 21 can be connected to slide backward on the inside of the sliding sleeve 20, thereby overcoming the spring 18 to connect the top plate 19 and move backward, releasing the restriction on the screw disk 14, and then by screwing the screw disk 14, the threaded rod 12 can be rotated under the constraint of the middle plate 13, and the threaded rod 12 is screwed with the threaded sleeve 11 to drive the vertical slider 10 to slide down on the inside of the vertical moving frame 9, driving the driving mechanism 15 and the active gear 16 to move downward. , and after being engaged in place, it is fixed by self-locking thread of threaded rod 12 and threaded sleeve 11, and under the elastic action of spring 18, the top plate 19 can be pushed forward to support the outside of screw disk 14 to prevent screw disk 14 from rotating without external force. During operation, after the screw rod 24 is screwed into the thread groove 23, it can be hoisted to the outside through the lifting ring 25 to place the housing 1 in the corresponding position. When the housing 1 is forced to move forward, the driving mechanism 15 runs, driving the driving gear 16 to rotate, and the driving gear 16 is engaged with the driven large gear 5. The driven large gear 5 drives the synchronous shaft 4, which rotates under the constraint of multiple sets of constraint bearings 3 fixedly connected by the connecting frame 2, so that the cutter head 6 rotates to tamp the soil.

[0032] This driving mechanism 15 is a well-known device purchased directly from the market by those skilled in the art. Here we only use it without making any structural or functional improvements to it, and we will not go into details here.
