[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0022] like Figure 1-5As shown, the present application discloses a movable and height-adjustable integrated micro pipe jacking machine, comprising a backrest plate 1, two guide rail brackets 2 are installed on the bottom of the backrest plate 1, and a reverse thrust cylinder 3 is installed on the guide rail bracket 2, and the same power box 4 is installed on the ends of the two reverse thrust cylinders 3, and the power box 4 is slidably arranged on the guide rail bracket 2, and a front end support plate 5 is also installed on the front ends of the two guide rail brackets 2, and a plurality of bottom steel plates 8 are arranged perpendicular to the two guide rail brackets 2 and at the bottom thereof, and two omnidirectional rollers 7 are respectively installed below the bottom steel plates 8 at the front and rear ends, and the two ends of the bottom steel plate 8 extend beyond the guide rail bracket 2 and are respectively installed with a height adjustment component 9;

[0023] Specifically, in order to facilitate the transportation of the pipe jacking machine, a plurality of bottom steel plates 8 are installed at the bottom of the guide rail bracket 2. On the one hand, the stability of the pipe jacking machine can be increased. On the other hand, the omnidirectional rollers 7 can be installed under the bottom steel plates 8 at the front and rear ends. By using the omnidirectional rollers 7, the forward direction of the pipe jacking machine can be adjusted at will when pushing, which is convenient for adjusting the position and transferring. In addition, when the position of the pipe jacking machine is determined, the pipe jacking machine needs to be supported and fixed. At this time, the height adjustment component 9 can be supported on the set I-beam or concrete platform, and the pipe jacking machine can be adjusted to a suitable height as required, which is convenient to use.

[0024] like Figure 1 , 4 As shown, the height adjustment component 9 includes a threaded sleeve 81 installed on the end of the bottom steel plate 8 and a support disc 91. A height adjustment screw 92 is installed at the top center of the support disc 91. The height adjustment screw 92 is threadedly connected and assembled inside the threaded sleeve 81, and a plug hole is penetrated on the top of the height adjustment screw 92. When in use, a steel bar can be inserted into the plug hole to bend the height adjustment screw 92 to rotate. Due to the threaded cooperation between the height adjustment screw 92 and the threaded sleeve 81, the height of the pipe jacking machine can be adjusted, and the center of the front side of the backrest plate 1 can be adjusted. A theodolite 6 is also installed at the position, an oil motor 42 is set at the center position of the top of the power box 4, and shift switches 41 are installed on both ends of the top of the power box 4. A level tube 43 and a digital angle ruler 44 are respectively installed on the top of the power box on both sides of the shift switch 41. The level tube 43 is a universal bubble level detector, and the digital angle ruler 44 can be used to measure the horizontal angle of the reverse thrust cylinder 3. The angle of the pipeline can then be measured by the set theodolite 6 to ensure that the pipeline will not deviate during jacking.

[0025] like Figure 1 , 2As shown in Figure 3, a slot is further provided on the top of the front end support plate 5, and an adjusting block 51 is installed in the slot. A limiting ring 53 adapted to the pipe is provided at the center of the adjusting block 51. The limiting ring 53 has various sizes, and an annular groove is provided on the inner wall of the limiting ring 53, and a plurality of roller rods 54 are arranged in an annular array in the annular groove. A plurality of extrusion springs 55 are further provided between the roller rods 54 and the inner wall of the annular groove. Furthermore, in order to prevent the position displacement of the pipe during the pipe jacking process, an adjusting block 51 is further provided on the front end support plate 5, and limiting rings 53 of different diameters are provided in different adjusting blocks 51. When in use, the limiting ring 53 can be adjusted according to the pipe diameter. The appropriate adjusting block 51 is selected according to the diameter size. In addition, a plurality of roller rods 54 are installed in the annular groove inside the limiting ring 53, and the roller rods 54 are connected to the annular groove through extrusion springs 55. Under the extrusion effect of the plurality of roller rods 54, the pipeline can be squeezed and limited to ensure the straight line operation of the pipeline. The extrusion springs 55 arranged on the roller rods 54 can effectively absorb the vibration of the pipeline, so that the pipeline can be pushed forward smoothly. Quick-release bolts 52 are respectively provided on both ends of the top of the adjusting block 51. The quick-release bolts 52 pass through the adjusting block 51 and are threadedly connected to the inside of the card slot. Due to the arrangement of the quick-release bolts 52, the block 51 can be easily removed and replaced, which is more convenient.

[0026] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0027] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] The implementation principle of the movable and height-adjustable integrated micro pipe jacking machine in the embodiment of the present application is as follows:

[0029] When in use, the pipe jacking machine is first hoisted in a pre-dug pit, and the height adjustment component 9 of the pipe jacking machine is set on the pre-buried I-beam or concrete platform, and the pipe jacking machine is adjusted to a horizontal level according to the indication of the level tube 43. Then, the height of the pipe jacking machine can be adjusted according to the buried position of the pipeline. First, a steel bar is passed through the jack at the top of the height adjustment screw 92, and the steel bar is moved to push the height adjustment screw 92 to rotate. Since the height adjustment screw 92 and the threaded sleeve 81 are matched, the height of the pipe jacking machine can be adjusted, and the angle of the pipeline can also be measured by the theodolite 6 and the digital angle ruler 44 to ensure that the pipeline will not deviate during the pipe jacking.

[0030] Then, you can select an adjustment block 51 that matches the diameter of the pipe. Since the adjustment block 51 and the front end support plate 5 are fixed with quick-release bolts 52, it is relatively easy to replace. When in use, you can select a suitable adjustment block 51 according to the diameter of the pipe. In addition, a plurality of roller rods 54 are installed in the annular groove inside the limiting ring 53, and the roller rods 54 are connected to the annular groove through extrusion springs 55. Under the extrusion effect of the plurality of roller rods 54, the pipe can be squeezed and limited to ensure that the pipe runs in a straight line. The extrusion spring 55 arranged on the roller rod 54 can effectively absorb the vibration of the pipeline, so that the pipeline can be pushed forward smoothly, and quick-release bolts 52 are respectively provided on the two ends of the top of the adjusting block 51. The quick-release bolts 52 pass through the adjusting block 51 and are threadedly connected inside the slot. Due to the setting of the quick-release bolts 52, the adjusting block 51 can be easily replaced. It is relatively convenient. When the pipeline passes through the limit ring and is pressed against the front side of the power box 4, the shift switch 41 on the power box 4 can be pried, and the power box 4 can be operated to slide on the guide rail bracket 2, thereby pushing the pipeline forward.
