[0024] Reference Figure 1 , Figure 2A pushing and loading device for pipe jacking construction comprises two sets of symmetrically arranged mounting frames 1, a loading frame 19 and a transmission assembly. The two sets of the mounting frames 1 are connected by a bottom frame 2. A plurality of fixed blocks 15 are arranged inside the bottom frame 2. The plurality of fixed blocks 15 are equidistantly distributed. The fixed blocks 15 are fixedly connected to a fixed shaft 16. A rolling support wheel 17 is rotatably connected to the fixed shaft 16. The provision of the rolling support wheel 17 can reduce the friction between the pipe 26 and the bottom frame 2, which is beneficial for the pushing assembly to push the pipe 26 to move. The mounting frame 1 is connected to the loading frame 19. Support frames 20 are arranged on both sides of the loading frame 19. The transmission assembly comprises a driving shaft 21, a driving member, a winding drum 22 and a steel cable 25. A driving member is fixedly connected to one side of the support frame 20. Specifically, the driving member is a motor 23. The output end of the motor 23 is fixedly connected to the end of the driving shaft 21. The support frame 20 is movably connected to the drive shaft 21, and the drive shaft 21 is fixedly connected to the winding drum 22. Specifically, two groups of symmetrically arranged winding drums 22 are fixedly connected to the drive shaft 21, and the steel cable 25 is arranged around the outside of the pipe 26. One end of the steel cable 25 is wound and connected to the outside of the winding drum 22, and the end of the steel cable 25 away from the winding drum 22 is fixed to the loading rack 19. Specifically, a mounting groove 24 is provided at the bottom of the loading rack 19, and the end of the steel cable 25 away from the winding drum 22 is fixed to the loading rack 19 through the mounting groove 24. Therefore, the motor 23 drives the rotating shaft 21 to rotate, and the rotation of the rotating shaft 21 can drive the winding drum 22 to rotate, and then the steel cable 25 wound on the winding drum 22 can be controlled to be retracted and released, so that the pipe 26 can be placed from the loading rack 19 to the bottom frame 2. A pushing assembly is provided at one end of the mounting frame 1. The pipe 26 falls into the bottom frame 2 along with the release assembly of the steel cable 25. The pushing assembly can push the pipe 26 to the place where the jacking construction is to be carried out, thereby realizing the installation of the pipe 26 and the jacking device without manual handling.

[0025] Specifically, refer to Figure 3 The pusher assembly includes a mounting plate 8 fixedly connected to one end of the mounting frame 1, a sliding cylinder 9 fixedly connected in the mounting plate 8, a sliding rod 10 slidably connected in the sliding cylinder 9, a connecting frame 11 fixedly connected at one end of the sliding rod 10, and a pusher frame 12 fixedly connected to the connecting frame 11. A cushion block 13 is fixedly connected to the pusher frame 12. A hydraulic telescopic pump 14 is fixedly connected to the mounting plate 8, and the output shaft of the hydraulic telescopic pump 14 is fixedly connected to the connecting frame 11. The hydraulic telescopic pump 14 can drive the connecting frame 11 to move, thereby driving the telescopic sliding of the pusher frame 12, so as to push the pipeline 26 through the pusher frame 12.

[0026] In order to facilitate the pipe 26 to fall from the loading rack 19 into the bottom frame 2, an inclined guide plate 7 is provided on the upper part of the mounting frame 1, and the mounting frame 1 is connected to the loading rack 19 through the inclined guide plate 7, and multiple groups of pipes 26 are placed on the loading rack 19. A protective block 18 is fixedly connected to the inner wall of the mounting frame 1. The protective block 18 can prevent dust and the like from falling directly into the fixed shaft 16 and affecting the rotation of the rolling support wheel 17.

[0027] The device is set on the ground, so the mounting frame 1 is provided with a support assembly, see Figure 2 The support assembly includes a support foot 3, which is fixedly connected to the outer wall of the mounting frame 1. A fixing tube 4 is fixedly connected to the bottom of the support foot 3. A gripping nail 5 is slidably connected inside the fixing tube 4. The gripping nail 5 passes through the fixing tube 4 and is fixedly connected to a connecting rod 6. Through the arrangement of the gripping nail 5 and the fixing tube 4, the support foot 3 is fixedly connected to the ground, thereby fixing the entire device on the ground.

[0028] In the jacking feeding device for pipe jacking construction provided by the utility model, the gripping nail 5 is first inserted into the ground through the connecting rod 6, and the supporting foot 3 is fixedly connected to the ground through the setting of the gripping nail 5 and the fixing tube 4, and then the whole feeding device is fixedly connected to the ground, and then the equipment is installed in the foundation pit, and then the pipe 26 is rolled and stacked on the feeding rack 19, and the steel cable 25 with one end fixed on the feeding rack 19 is wrapped around the bottom of the pipe 26 and connected to the winding drum 22, and the steel coil is wound by the winding drum 22. When it is necessary to load the pipe 26, the motor 23 can be used to drive the rotating shaft to rotate, thereby driving the winding drum 22 fixedly connected to the rotating shaft to rotate, so as to release the steel cable 25. While the steel cable 25 is being released, a group of pipes 26 will slide along the inclined guide plate 7 toward the bottom frame 2. The sliding speed of the pipe 26 is related to the speed at which the motor 23 controls the cable to be released. Finally, the pipe 26 will fall onto the rolling support wheel 17 on the bottom frame 2, and the sliding connection of the push frame 12 is realized through the sliding connection between the sliding cylinder 9 and the sliding rod 10. After that, the push frame 12 is driven by the hydraulic telescopic pump 14 to slide and retract, and then the pipe 26 is pushed by the push frame 12, so as to carry out the jacking construction. In the process of jacking, the pad 13 is set to avoid damage to the pipe 26 caused by the rigid contact between the push frame 12 and the pipe 26. After completing the jacking installation of the pipe 26, the steel cable 25 is retracted to continue loading the next group of pipes 26.

[0029] The utility model provides a jacking loading device for pipe jacking construction, which controls the release of a steel cable 25 through a motor 23, places a pipe 26 on a rolling support wheel 17, and then pushes the pipe 26 through a pushing assembly, thereby performing pipe jacking construction. After completing the pipe jacking installation of the pipe 26, the steel cable 25 is retracted, and the loading of the next group of pipes 26 is continued. During the entire loading process, no workers are required to carry the materials, which eliminates safety hazards, reduces the labor intensity of workers, and improves the practicability of the equipment.
