Technical Field

[0001] The utility model relates to the technical field of pipe jacking deviation correction, in particular to a circular pipe jacking deviation correction and adjustment pipe. Background Technique

[0002] Pipe jacking is a construction technique commonly used for non-excavation pipeline laying in municipal construction. Its advantages are that it has little or no impact on the surrounding environment, requires a small construction site, and generates little noise. Pipe jacking can carry out underground operations, which is an incomparable advantage of excavated buried pipes. However, pipe jacking technology also has disadvantages, such as a long construction time and high project cost.

[0003] In the prior art, when two circular pipe jackings are under construction, due to the difference in their heights, deviation correction is required before other operations can be carried out. Currently, the position adjustment of the existing deviation correction devices during pipe positioning is not very precise, which may lead to the influence on the working effect of other operations between the two pipes during daily use, resulting in errors or other situations. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a circular pipe jacking deviation correction and adjustment pipe, which solves the problem that the position adjustment of the existing deviation correction devices during pipe positioning is not very precise, which may lead to the influence on the working effect of other operations between the two pipes during daily use, resulting in errors or other situations.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A circular pipe jacking deviation correction and adjustment pipe includes an adjustment mechanism and a deviation correction mechanism. A first pipe and a second pipe are respectively arranged inside the adjustment mechanism and the deviation correction mechanism. The adjustment mechanism includes:

[0006] An arc-shaped fixing plate, which is sleeved outside the first pipe. A plurality of threaded rods are threadedly connected to the outside of the arc-shaped fixing plate. The end of the threaded rod is rotatably provided with a pipe positioning plate, and a plurality of pipe positioning plates are in contact with the outside of the first pipe;

[0007] A plurality of lead screws, which are arranged outside the arc-shaped fixing plate;

[0008] The deviation correction mechanism includes a deviation correction pipe, which is sleeved outside the second pipe and is arranged between a plurality of lead screws.

[0009] Preferably, a plurality of first mounting blocks are fixedly installed on the outside of the arc-shaped fixing plate, and a plurality of first mounting blocks are respectively threadedly connected to a plurality of lead screws.

[0010] Preferably, a first hexagonal nut is threadedly connected to the outer side of the lead screw, and the outer side of the first hexagonal nut abuts against the first mounting block.

[0011] Preferably, the deviation correction pipe is conical. A plurality of second mounting blocks are fixedly connected to the outer side of the end with a larger diameter of the deviation correction pipe, and the plurality of second mounting blocks are respectively threadedly connected to the plurality of lead screws.

[0012] Preferably, a second hexagonal nut is threadedly connected to the outer side of the lead screw, and the outer side of the second hexagonal nut abuts against the second mounting block.

[0013] Preferably, a rolling mechanism is further arranged on the outer side of the lead screw. The rolling mechanism includes a positioning block fixedly arranged on the outer side of the lead screw. A rotating shaft is fixedly connected to the end of the positioning block. A roller support block is rotatably connected to the surface of the rotating shaft. A roller shaft is fixedly connected to one side of the roller support block, and a roller is fixedly connected to the inner surface of the roller shaft.

[0014] Preferably, a handle is fixedly connected to the end of the threaded rod.

[0015] Preferably, a bearing is installed at the connection between the end of the threaded rod and the pipe positioning plate.

[0016] Preferably, a spring is arranged between the inner ring surface of the arc-shaped fixing plate and the outer side of the pipe positioning plate, and the spring is movably sleeved on the bottom end of the threaded rod and the outer side of the bearing.

[0017] The utility model discloses a circular pipe jacking deviation correction adjusting pipe, and the beneficial effects thereof are as follows:

[0018] 1. For this circular pipe jacking deviation correction adjusting pipe, first, the angle of the first pipe can be adjusted by using the pipe positioning plate, and the first pipe can also be fixed more firmly around. After the first pipe is fixed, the second pipe is pushed so that the surface of the second pipe contacts the inner surface of the deviation correction pipe. Since the inner surface diameter of the deviation correction pipe decreases sequentially from outside to inside and is a smooth arc surface, it is convenient for the surface of the second pipe to slide. And a circular ring is arranged on the front surface of the deviation correction pipe. The second pipe is pushed beyond the end surface of the deviation correction pipe and then positioned with the first pipe to realize the deviation correction function. The staff can weld and perform other operations on the first pipe and the second pipe.

[0019] 2. For this circular pipe jacking deviation correction adjusting pipe, during construction, the rollers can contact the walls and other surfaces at the construction site. Since the rollers rotate on the inner surface of the roller shaft, and the rotating shaft rotating on the inner surface of the roller support block is fixed on the inner surface of the positioning block, when an obstacle on the wall and other surfaces contacts the rollers, the roller support block moves downward, so that the upper rollers move accordingly. During construction, the stability of the device during operation can be improved by the support of multiple rollers. Description of the Drawings

[0027] To better understand the above technical solutions, the following will specifically describe the above technical solutions in detail in conjunction with the accompanying drawings of the specification and specific embodiments.

[0028] An embodiment of the present invention discloses a circular pipe jacking deviation rectification and adjustment pipe. As shown in the attached Figures 1-5 figure, it includes an adjustment mechanism 1 and a deviation rectification mechanism 2. The inner sides of the adjustment mechanism 1 and the deviation rectification mechanism 2 are respectively provided with a first pipeline 101 and a second pipeline 201. The adjustment mechanism 1 includes:

[0029] An arc-shaped fixing plate 102, which is sleeved on the outer side of the first pipeline 101. A plurality of threaded rods 105 are threadedly connected to the outer side of the arc-shaped fixing plate 102. The end of the threaded rod 105 is rotatably provided with a pipeline positioning plate 103, and a plurality of pipeline positioning plates 103 are in contact with the outer side of the first pipeline 101;

[0030] A plurality of lead screws 108 are arranged on the outer side of the arc-shaped fixing plate 102;

[0031] The deviation rectifying mechanism 2 includes a deviation rectifying pipe 202 which is sleeved on the outer side of the second pipe 201, and the deviation rectifying pipe 202 is arranged between the plurality of lead screws 108.

[0032] First, the pipe positioning plate 103 can be used to adjust the angle of the first pipe 101, and the first pipe 101 can also be fixed more firmly around it; after the first pipe 101 is fixed, the second pipe 201 is pushed so that the surface of the second pipe 201 contacts the inner surface of the deviation rectifying pipe 202. Since the inner surface diameter of the deviation rectifying pipe 202 decreases sequentially from outside to inside and is a smooth arc surface, it is convenient for the surface of the second pipe 201 to slide. And a circular ring is arranged on the front surface of the deviation rectifying pipe 202. The second pipe 201 is pushed beyond the end surface of the deviation rectifying pipe 202, and then positioned with the first pipe 101 to realize the function of deviation rectification. The staff can weld and perform other operations on the first pipe 101 and the second pipe 201.

[0033] Furthermore, a plurality of first mounting blocks 109 are fixedly installed on the outer side of the arc-shaped fixing plate 102, and the plurality of first mounting blocks 109 are respectively threadedly connected with the plurality of lead screws 108.

[0034] Furthermore, a first hexagonal nut 110 is threadedly connected to the outer side of the lead screw 108, and the outer side of the first hexagonal nut 110 abuts against the first mounting block 109.

[0035] Specifically disclosed, the deviation rectifying pipe 202 is set to be conical. A plurality of second mounting blocks 203 are fixedly connected to the outer side of the end with a larger diameter of the deviation rectifying pipe 202, and the plurality of second mounting blocks 203 are respectively threadedly connected with the plurality of lead screws 108.

[0036] Preferably, a second hexagonal nut 204 is threadedly connected to the outer side of the lead screw 108, and the outer side of the second hexagonal nut 204 abuts against the second mounting block 203.

[0037] [[ID=2 — 2]]Specifically disclosed, a rolling mechanism 3 is further arranged on the outer side of the lead screw 108. The rolling mechanism 3 includes a positioning block 301 fixedly arranged on the outer side of the lead screw 108. A rotating shaft 302 is fixedly connected to the end of the positioning block 301. A roller support block 303 is rotatably connected to the surface of the rotating shaft 302. A roller shaft 304 is fixedly connected to one side of the roller support block 303. A roller 305 is fixedly connected to the inner surface of the roller shaft 304.

[0038] During construction, the roller 305 can contact the walls and other surfaces at the site. Since the roller 305 rotates on the inner surface of the roller shaft 304, and the rotating shaft 302 that rotates on the inner surface of the roller support block 303 is fixed on the inner surface of the positioning block 301, when an obstacle on the wall or other surfaces touches the roller 305, the roller support block 303 moves downward, and thus the upper roller 305 follows to move. During construction, the support of multiple rollers 305 can improve the stability of the device during operation.

[0039] Further, a handle 107 is fixedly connected to the end of the threaded rod 105.

[0040] Further, a bearing 104 is installed at the connection between the end of the threaded rod 105 and the pipe positioning plate 103.

[0041] Further, a spring 106 is provided between the inner ring surface of the arc-shaped fixing plate 102 and the outside of the pipe positioning plate 103, and the spring 106 is movably sleeved on the bottom end of the threaded rod 105 and the outside of the bearing 104.

[0042] During the construction process, the staff first inserts the first pipe 101 between multiple pipe positioning plates 103. By rotating the rotating handle 107, the lower threaded rod 105 rotates on the inner surface of the bearing 104, and the threaded rod 105 rotates relative to the arc-shaped fixing plate 102, and can adjust the lower pipe positioning plate 103. Since the pipe positioning plates 103 are evenly distributed around, the angle of the first pipe 101 can be adjusted, and the first pipe 101 can also be fixed more tightly around.

[0043] After the first pipe 101 is fixed, the second pipe 201 is pushed so that the surface of the second pipe 201 contacts the inner surface of the deviation correction pipe 202. Since the inner surface diameter of the deviation correction pipe 202 decreases sequentially from the outside to the inside and is a smooth arc surface, it is convenient for the surface of the second pipe 201 to slide. And there is a ring on the front of the deviation correction pipe 202. The second pipe 201 is pushed beyond the end face of the deviation correction pipe 202, and then is positioned with the first pipe 101 to achieve the function of deviation correction. The staff can weld and perform other operations on the first pipe 101 and the second pipe 201.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
