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.

[0026] See also Figures 1 to 5 The utility model describes the above technical solution in detail through the following embodiments:

[0027] A pipe jacking construction device, comprising a pipe jacking frame 2 for jacking up a pipe body 1, a first pipe jacking seat 3 is arranged at the center of the pipe jacking frame 2, a second pipe jacking seat 4 is slidably arranged at the bottom of the first pipe jacking seat 3, a first pipe jacking unit is arranged between the second pipe jacking seat 4 and the first pipe jacking seat 3, two clamping plates 5 are symmetrically slidably arranged at the bottom of the second pipe jacking seat 4, a second pipe jacking unit is arranged between the two clamping plates 5 and the second pipe jacking seat 4, a first clamping block 6 is fixedly arranged on the opposite sides of the two clamping plates 5, and a second clamping block 6 is slidably arranged above the first clamping block 6. Two clamping blocks 7, a third jacking unit is provided between the second clamping block 7 and the clamping plate 5, so that the two clamping plates 5 drive the first clamping block 6 to slide to the bottom of the pipe body 1 through the second jacking unit, and then the second clamping block 7 is slid to the top of the pipe body 1 through the third jacking unit, and then the pipe body 1 is clamped by the second clamping block 7 and the first clamping block 6. At this time, the second jacking seat 4 is raised through the first jacking unit, so that the pipe body 1 can be quickly jacked up. It is not only simple to operate, but also can effectively improve the jacking efficiency.

[0028] like Figure 1 and Figure 2As shown, the first jacking unit includes a first jacking tube plate 31, a first limiting block 32 and a first jacking tube column 33. The first jacking tube seat 3 is provided with a first jacking tube cavity inside. The first jacking tube plate 31 is slidably arranged inside the first jacking tube cavity. Two first limiting grooves are symmetrically arranged on the inner wall of the first jacking tube cavity. The first limiting block 32 is symmetrically arranged on the first jacking tube plate 31. The first limiting block 32 is slidably arranged inside the first limiting groove. The jacking tube column is arranged on the bottom surface of the first jacking tube plate 31. The bottom end of the jacking tube column extends to the bottom of the first jacking tube seat 3. The second jacking tube seat 4 is arranged on the bottom end of the jacking tube column. The first jacking tube unit also includes a first jacking tube spring 3 4. The first top tube spring 34 is arranged between the first top tube plate 31 and the inner wall of the first top tube cavity, so that the first top tube column 33 can slide up and down through the cooperation of the first top tube plate 31 and the first limit block 32. At the same time, the first top tube column 33 remains stable when sliding through the cooperation of the first limit block 32 and the first limit groove. When the first top tube column 33 is pulled to slide downward, the first top tube plate 31 will squeeze the first top tube spring 34 to deform it. When the force pulling the first top tube column 33 is cancelled, the first top tube plate 31 will drive the first top tube column 33 to move upward under the elastic force of the first top tube spring 34 to restore the deformation.

[0029] like Figure 3 and Figure 4 As shown, the second top tube unit includes a second top tube plate 41, a second linkage tooth plate 42 and a second linkage gear 43. The second top tube seat 4 is provided with a second top tube cavity inside, and two second limiting grooves are provided at the bottom of the second top tube seat 4. The second limiting groove is connected to the second top tube cavity. The second top tube plate 41 is arranged at the top of the clamping plate 5. The two second top tube plates 41 are respectively slidably arranged inside the two second limiting grooves. The second linkage tooth plate 42 is arranged at the top of the second top tube plate 41. The two second linkage tooth plates 42 are both slidably arranged inside the second top tube cavity. The second linkage gear 43 is rotatably arranged inside the second top tube cavity. The second linkage gear 43 is connected to the two second linkage tooth plates 42. The second top tube unit also includes a second linkage gear 43. The second top tube spring 44 is arranged between the second linkage tooth plate 42 and the inner wall of the second top tube cavity, so that the two clamping plates 5 can slide relative to each other through the cooperation of the second top tube plate 41, the second linkage tooth plate 42 and the second linkage gear 43. At the same time, the cooperation of the second top tube plate 41 and the second limit groove makes the two clamping plates 5 remain stable when sliding. When the two clamping plates 5 are pulled away from each other to slide, the second linkage tooth plate 42 will stretch the second top tube spring 44 to deform it. When the force pulling the two clamping plates 5 is cancelled, the second linkage tooth plate 42 will cooperate with the second linkage gear 43 to drive the two clamping plates 5 to slide closer to each other under the elastic force of the second top tube spring 44 to restore the deformation.

[0030] like Figure 5As shown, the third jacking tube unit includes a third jacking tube plate 71 and a third limiting block 72, a third jacking tube hole is provided on the clamping plate 5, the third jacking tube plate 71 is arranged on a side of the second clamping block 7 close to the clamping plate 5, the third jacking tube plate 71 is slidably arranged inside the third jacking tube hole, and two third limiting grooves are symmetrically arranged on the inner wall of the third jacking tube hole, the third limiting block 72 is symmetrically arranged on the third jacking tube plate 71, and the third limiting block 72 is slidably arranged inside the third limiting groove, the third jacking tube unit also includes a third jacking tube spring 73, the third jacking tube spring 73 is arranged between the third limiting block 72 and the inner wall of the third limiting groove, the third jacking tube unit also includes a pull block 74 and a locking rod 75, the pull block 74 is arranged on the third jacking tube plate 71 away from the second clamping block 7 The locking rod 75 is rotatably arranged inside the locking threaded hole, so that the second clamping block 7 can slide up and down through the third jacking plate 71. At the same time, the cooperation between the third limit block 72 and the third limit groove makes the second clamping block 7 remain stable when sliding. When the pull block 74 is pulled to slide upward, the third limit block 72 will squeeze the third jacking spring 73 to deform it. When the force of pulling the pull block 74 is cancelled, the third limit block 72 will slide downward under the elastic force of the third jacking spring 73 to restore the deformation, thereby driving the second clamping block 7 to clamp the tube body 1 lifted by the first clamping block 6. At this time, the pull block 74 can be locked by the locking rod 75, thereby completing the jacking work.

[0031] Working principle: first, place the jacking frame 2 on the top of the pipe body 1, then press the second jacking seat 4 with one hand to pull it downward, and at the same time pull one of the clamping plates 5 with the other hand to pull it outward. When the second jacking seat 4 is pulled downward, the second jacking seat 4 will drive the first jacking plate 31 connected to the first jacking column 33 to slide downward, and the first jacking plate 31 will squeeze the first jacking spring 34 to deform it when it slides downward. When one of the clamping plates 5 is pulled outward, the two clamping plates 5 will slide relative to each other under the cooperation of the second jacking plate 41, the second linkage tooth plate 42 and the second linkage gear 43. When the second linkage tooth plate 42 slides, it will stretch the second jacking spring 44 to deform it. When the second jacking seat 4 is pulled downward to the state where the first clamping block 6 is in contact with the ground, the clamping plate 5 can be released, so that the two clamping plates 5 are in the second jacking spring The spring 44 slides inwardly under the elastic force of the deformation recovery of the spring 44, thereby causing the first clamping blocks 6 on the two clamping plates 5 to contact the bottom of the tube body 1. At this time, the second jacking tube seat 4 can be released, so that the second jacking tube seat 4 can slide upward under the elastic force of the first jacking tube spring 34 to recover the deformation, and then the tube body 1 is lifted up by the first clamping blocks 6 on the two clamping plates 5. At this time, the locking rod 75 can be rotated counterclockwise to release the locking state of the pulling block 74, thereby releasing the locking state of the second clamping block 7, and then the second clamping block 7 slides downward under the elastic force of the deformation recovery of the third jacking tube spring 73, thereby driving the second clamping block 7 to clamp the tube body 1 lifted by the first clamping block 6. At this time, the pulling block 74 can be locked by rotating the locking rod 75 clockwise, so that the tube bodies 1 of different diameters can be quickly clamped, thereby quickly completing the jacking work.
