Description

Technical Field

[0001] The utility model belongs to the technical field of pipe jacking supports, and in particular relates to a pipe jacking auxiliary device for the pipe jacking support. Background Art

[0002] Pipe jacking technology is a trenchless pipe laying technology commonly used in municipal construction. It allows the pipe to be pushed underground section by section through jacking equipment without excavating the surface. A pipe jacking support usually refers to a supporting structure used in the pipe jacking construction process. It is used to fix and support the pipe jacking machine and its working pipe to ensure the safety and accuracy of construction. In summary, the problems existing in the existing technology are: pipe jacking supports include various types such as fixed supports, sliding supports, guide supports and rolling supports. The corresponding pipe jacking supports are selected according to different steps in the pipe jacking construction. When the pipe is pushed into the tunnel, a support is needed to support the pipe to prevent the pipe from tilting or sinking. The existing pipe support only has a supporting function. If the position of the pipe entering the tunnel is not restricted, the pipe movement angle is likely to deviate, reducing the construction accuracy. However, the pipe jacking support used in the existing pipe jacking does not have a component that provides more stable support for the pipe. Therefore, a pipe jacking support with a pipe jacking auxiliary device is proposed to solve the above problems. Utility Model Content

The corresponding jacking support is selected according to different steps in the jacking construction. When the pipeline is pushed into the tunnel, the support needs to be used to support the pipeline to prevent the pipeline from tilting or sinking. The existing pipeline support only has a supporting function. If the position where the pipeline enters the tunnel is not restricted, the pipeline movement angle is likely to deviate, reducing the construction accuracy. However, the jacking support used for the existing pipe jacking does not have a component that provides more stable support for the pipeline.

[0004] The utility model is implemented as follows: a pipe jacking auxiliary device for a pipe jacking support comprises a support frame and a pipe, the pipe being movably connected to the top of the support frame, four adjusting shells being fixedly connected to the top of the support frame, four transverse rollers being provided on the top of the support frame, the transverse rollers being movably connected to the surfaces of the adjusting shells via rotating shafts, the surfaces of the transverse rollers being in contact with the surface of the pipe, four vertical rollers being provided on the top of the support frame for use in conjunction with the pipe, and two moving devices being provided in the inner cavity of the support frame.

[0005] As a preferred embodiment of the present invention, the moving device includes two moving frames, and four moving blocks used in conjunction with the moving frames are fixedly connected to the top of the bracket frame. The surfaces of the moving blocks are movably connected to the inner cavity of the moving frame, and the opposite sides of the two moving frames are fixedly connected with springs. By setting up the moving device, when the vertical roller needs to adjust its position as needed, the moving device has an adjusting effect on the position of the vertical roller.

[0006] As a preferred embodiment of the present invention, the movable frame is fixedly connected to an extrusion column on one side close to the inner cavity of the bracket frame, and the inner cavity of the bracket frame is movably connected to four extrusion rotating frames used in conjunction with the extrusion column through a rotating shaft. The inner cavity of the extrusion rotating frame is movably connected to the surface of the extrusion column. By arranging the extrusion column and the extrusion rotating frame, when the extrusion rotating frame rotates, an extrusion force can be generated on the extrusion column. The extrusion force generated by the extrusion rotating frame on the extrusion column can drive the extrusion column to move, and when the extrusion column moves, the movable frame can be driven to move.

[0007] As a preferred embodiment of the present invention, the inner cavity of the bracket frame is movably connected with a movable control rod used in conjunction with the extrusion rotating frame, and the surface of the movable control rod is movably connected to the inner cavity of the extrusion rotating frame.

[0008] As a preferred embodiment of the present invention, four limit rods are fixedly connected to the bottom of the inner cavity of the bracket frame, and two limit holes are provided on the surface of the movable control rod for use in conjunction with the limit rods. The surface of the limit rod is movably connected to the inner cavity of the limit hole. By setting the limit rod and the limit hole, the movable control rod is pressed to drive the limit hole to move along the surface of the limit rod. The coordinated use of the limit rod and the limit hole has a limiting effect on the moving position of the movable control rod.

[0009] As a preferred embodiment of the present invention, two adjustment frames used in conjunction with the vertical rollers are provided on one side of the bracket frame close to the movable frame.

[0010] As a preferred embodiment of the present invention, two moving grooves are provided on the surface of the adjustment frame for use with the moving frame. The opposite sides of the two moving frames pass through the adjustment shell and contact the inner cavity of the moving groove. By setting the moving groove, when the adjustment frame moves to the appropriate position, the moving control rod is released, and the restoring force generated by the spring restoring its shape will drive the moving frame to be stuck in the inner cavity of the moving groove.

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, an embodiment of the utility model provides a pipe jacking auxiliary device for a pipe jacking support, comprising a support frame 1 and a pipe 2, the pipe 2 being movably connected to the top of the support frame 1, the top of the support frame 1 being fixedly connected with four adjusting shells 3, the top of the support frame 1 being provided with four transverse rollers 4, the transverse rollers 4 being movably connected to the surface of the adjusting shell 3 through a rotating shaft, the surface of the transverse rollers 4 being in contact with the surface of the pipe 2, the top of the support frame 1 being provided with four vertical rollers 5 for use with the pipe 2, and the inner cavity of the support frame 1 being provided with two moving devices 6.

[0022] refer to Figure 4 The moving device 6 includes two moving boxes 601. Four moving boxes 602 used in conjunction with the moving boxes 601 are fixedly connected to the top of the bracket frame 1. The surface of the moving box 602 is movably connected to the inner cavity of the moving box 601. The opposite side of the two moving boxes 601 is fixedly connected with a spring 603.

[0023] With the above solution, by providing the moving device 6 , when the position of the vertical roller 5 needs to be adjusted as needed, the moving device 6 has an adjusting effect on the position of the vertical roller 5 .

[0024] refer to Figure 3 The side of the movable box 601 close to the inner cavity of the bracket frame 1 is fixedly connected with an extrusion column 7. The inner cavity of the bracket frame 1 is movably connected with four extrusion rotating frames 8 used in conjunction with the extrusion column 7 through a rotating shaft. The inner cavity of the extrusion rotating frame 8 is movably connected to the surface of the extrusion column 7.

[0025] The above solution is adopted: by setting the extrusion column 7 and the extrusion rotating frame 8, when the extrusion rotating frame 8 rotates, it can generate an extrusion force on the extrusion column 7. The extrusion force generated by the extrusion rotating frame 8 on the extrusion column 7 can drive the extrusion column 7 to move. When the extrusion column 7 moves, it can drive the moving frame 601 to move.

[0026] refer to Figure 4The inner cavity of the stent frame 1 is movably connected to a movable control rod 9 used in conjunction with the extrusion rotating frame 8, and the surface of the movable control rod 9 is movably connected to the inner cavity of the extrusion rotating frame 8.

[0027] The above solution is adopted: by setting the movable control rod 9, when the movable control rod 9 moves, it can generate an extrusion force on the extrusion rotating frame 8, and the extrusion force generated by the movable control rod 9 on the extrusion rotating frame 8 can drive the extrusion rotating frame 8 to rotate through the rotating shaft.

[0028] refer to Figure 1 Four limiting rods 10 are fixedly connected to the bottom of the inner cavity of the bracket frame 1, and two limiting holes 11 are opened on the surface of the movable control rod 9 for use with the limiting rods 10. The surface of the limiting rod 10 is movably connected to the inner cavity of the limiting hole 11.

[0029] The above solution is adopted: by setting the limit rod 10 and the limit hole 11, pressing the movable control rod 9, driving the limit hole 11 to move along the surface of the limit rod 10, and the coordinated use of the limit rod 10 and the limit hole 11 has a limiting effect on the moving position of the movable control rod 9.

[0030] refer to Figure 2 Two adjustment frames 12 for use with the vertical roller 5 are provided on one side of the bracket frame 1 close to the movable frame 601. The bottom of the vertical roller 5 is movably connected to the surface of the adjustment frame 12 through a rotating shaft, and the surface of the adjustment frame 12 is movably connected to the inner cavity of the adjustment shell 3.

[0031] With the above solution, by providing the adjustment frame 12 , when the vertical roller 5 moves, the adjustment frame 12 will be driven to move along the inner cavity of the adjustment shell 3 . The cooperation between the adjustment frame 12 and the adjustment shell 3 has a limiting effect on the moving position of the vertical roller 5 .

[0032] refer to Figure 2 The surface of the adjustment frame 12 is provided with two moving grooves 13 for use with the moving frame 601 . The opposite sides of the two moving frames 601 both penetrate the adjustment shell 3 and contact the inner cavity of the moving grooves 13 .

[0033] The above solution is adopted: by setting the movable groove 13, when the adjustment frame 12 moves to the appropriate position, the movable control rod 9 is released, and the restoring force generated by the spring 603 restoring its shape will drive the movable frame 601 to be stuck into the inner cavity of the movable groove 13. The coordinated use of the movable frame 601 and the movable groove 13 has a limiting effect on the position of the adjustment frame 12.

[0034] The working principle of this utility model:

[0035] When in use, when the jacking support used for jacking pipes needs to provide more stable support for the pipe 2, the operator first places the pipe 2 on the top of the horizontal roller 4, and then presses the movable control rod 9 toward the bottom. When the movable control rod 9 moves, it will drive the limiting hole 11 to move along the surface of the limiting rod 10. When the movable control rod 9 moves, it will generate a downward extrusion force on the four extrusion rotating frames 8. The extrusion rotating frames 8 subjected to the extrusion force will rotate along the surface of the extrusion column 7 through the rotating shaft. The two extrusion columns 7 subjected to the extrusion force will move toward each other. When the extrusion column 7 moves, it will drive the moving box 601 to move along the surface of the moving block 602. At the same time, the extrusion force generated by the movement of the moving box 601 causes the spring 603 to produce an elastic shape. When the moving frame 601 is out of contact with the inner cavity of the moving groove 13, the adjusting frame 12 is pushed toward the side close to the pipe 2, driving the adjusting frame 12 to move along the inner cavity of the adjusting shell 3. When the adjusting frame 12 moves, the vertical roller 5 will be driven to move. When the surface of the vertical roller 5 contacts the surface of the pipe 2, the moving control rod 9 is released, and the restoring force generated by the spring 603 restoring its shape will drive the moving frame 601 to be stuck in the inner cavity of the moving groove 13. The coordinated use of the moving frame 601 and the moving groove 13 has a limiting effect on the position of the adjusting frame 12 and the vertical roller 5. The coordinated use of the vertical roller 5 and the horizontal roller 4 has a limiting effect on the moving position of the pipe 2. At this time, the jacking support used for the jacking pipe provides more stable support for the pipe 2.

[0036] In summary, the jacking auxiliary device for the jacking support solves the problem that the existing jacking supports include various types such as fixed supports, sliding supports, guide supports and rolling supports by setting the movable device 6, the movable box 601, the movable block 602, the spring 603 and the movable groove 13. The corresponding jacking supports are selected according to different steps in the jacking construction. When the pipeline is pushed into the tunnel, the support needs to be used to support the pipeline to prevent the pipeline from tilting or sinking. The existing pipeline support only has a supporting function. If the position of the pipeline entering the tunnel is not restricted, the pipeline movement angle is likely to deviate, reducing the construction accuracy. However, the jacking supports used in the existing jacking do not have a component that provides more stable support for the pipeline.
