[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 to Figure 6 , which is the first embodiment of the utility model, provides a steel pipe jacking device, which solves the problems of large workload, high construction cost and low efficiency of segmented welding of steel pipes, and includes a main body 100, a receiving component 200, and a moving component 300.

[0034] Specifically, the main body 100 includes a bracket 101 and a pusher 102 . The pusher 102 is disposed at the top end of the outer side of the bracket 101 . When the pusher 102 is working, it moves along the outer side of the bracket 101 .

[0035] Furthermore, the receiving assembly 200 includes a clamping member 201, a pressing member 202, and a connecting member 203. The clamping member 201 is arranged at the top end of the outer side of the bracket 101, and the clamping member 201 is movably connected to the pressing member 202 through the connecting member 203. When the pressing member 202 moves, the connecting member 203 rotates, and at the same time, the connecting member 203 is displaced in the opposite direction of the movement of the pressing member 202. Since the connecting member 203 is movably connected to the clamping member 201, when the connecting member 203 is displaced, the clamping member 201 is displaced synchronously.

[0036] Furthermore, the moving component 300 includes a rotating member 301 and a snap-on member 302. The rotating member 301 is arranged at the bottom end of the clamping member 201, and the snap-on member 302 is installed at the outer bottom end of the pressing member 202. When the pressing member 202 moves downward, the snap-on member 302 is driven to move downward, thereby unlocking the rotating member 301, and the rotating member 301 can then produce corresponding movement.

[0037] When in use, first embed a steel plate above the concrete bottom plate of the caisson, weld and fix the track to the embedded steel plate, then weld the bottom of the bracket 101 to the track, and weld and fix the reaction seat steel plate to the embedded steel bars in the well wall. Workers place the pushing member 102 on the bracket 101, fix the pushing member 102 by the limiting steel bars, and when the pushing member 102 works, it will drive the bracket 101 to move.

[0038] After the workers install the bracket 101, they then place the welded steel pipe horizontally on the bracket 101. When the steel pipe descends, the bottom of the steel pipe will contact the pressing piece 202. The pressing piece 202 moves downward due to the weight of the steel pipe, thereby driving the clamping piece 201 to move toward each other, and then clamp the outer wall of the steel pipe to achieve preliminary fixation of the steel pipe. Then, through the limiting ring on the outer wall of the steel pipe, the steel bar is passed through the limiting ring to fix the steel pipe above the clamping piece 302 to achieve final fixation of the steel pipe.

[0039] When the steel pipe is not installed, the rotating part 301 is in a locked state. When the pressing part 202 is pressed down to a certain height by the steel pipe, the clamping part 302 will unlock the rotating part 301, so that the rotating part 301 can move along with the steel pipe. When the pushing part 102 starts to work, the power source for the rotation of the rotating part 301 can be provided through the limiting ring, and then the steel pipe can move forward with the pushing part 102, repeatedly and slowly inserted into the place where it needs to be inserted.

[0040] In summary, the steel pipe is supported by the bracket 101, and the receiving component 200 clamps the steel pipe after it is lowered to achieve its initial fixation. While fixing the steel pipe, the receiving component 200 unlocks the clamping function of the moving component 300, so that the steel pipe can still be horizontally displaced after being fixed. The pushing member 102 starts to push the steel pipe forward and gradually clamps the steel pipe into the required jacking pipe, which reduces the workers' work content, improves efficiency, and reduces construction costs.

[0041] Example 2

[0042] Reference Figures 1 to 8 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment,

[0043] Specifically, the clamping member 201 includes a clamping jaw 201a, a movable base 201b and a rotating rod 201c. The clamping jaw 201a is movably connected to the movable base 201b through the rotating rod 201c. When the clamping jaw 201a is squeezed and rotated, it rotates around the rotating rod 201c as the axis center, and the movable base 201b is movably connected to the connecting member 203, that is, when the connecting member 203 rotates, the movable base 201b does not rotate, and when the connecting member 203 is displaced, the movable base 201b also moves accordingly.

[0044] The clamping member 201 also includes a first torsion spring 201d and a movable plate 201f. The first torsion spring 201d is arranged on the outside of the rotating rod 201c. When the clamping jaw 201a rotates, the first torsion spring 201d will enter a tension state. When the external force is lost, the first torsion spring 201d will drive the clamping jaw 201a to return to its original position, and the movable plate 201f is in contact with and connected to the bottom end of the movable base 201b, that is, the movable base 201b moves on the movable plate 201f.

[0045] Furthermore, the connecting member 203 includes a moving rod 203a and a first gear 203b. The first gear 203b is installed on the outside of the moving rod 203a. When the first gear 203b rotates forward, the moving rod 203a can rotate forward accordingly. The two ends of the outer side of the moving rod 203a are movably connected to one end of the outer side of the moving base 201b. The rotation of the moving rod 203a drives the moving base 201b to move.

[0046] Furthermore, the pressing member 202 includes a load-bearing block 202a, a pushing block 202b and a first rack 202c. The first rack 202c is installed at the top of the pushing block 202b, and the first rack 202c is in contact with the first gear 203b, that is, the first gear 203b rotates on the first rack 202c. When the first rack 202c moves, the first gear 203b is displaced in the opposite direction. The load-bearing block 202a is arranged on the outside of the pushing block 202b. The load-bearing block 202a is in contact with the pushing block 202b. When the load-bearing block 202a descends, it will push the pushing block 202b to move to both sides, and a push rod 202a-1 is installed at the bottom of the load-bearing block 202a, and the push rod 202a-1 descends as the load-bearing block 202a descends.

[0047] Preferably, the bottom end of the load-bearing block 202a is trapezoidal, and the bottom end of the trapezoid fits with one end of the push block 202b.

[0048] Furthermore, the clamping member 302 includes a chassis 302a, a clamping block 302b, a second torsion spring 302c and a support rod 302d. The chassis 302a is installed at the bottom end of the push rod 202a-1. The chassis 302a moves with the lifting and lowering of the push rod 201a-1, and the support rod 302d is fixedly connected to both ends of the chassis 302a. The clamping block 302b is rotatably connected to the end of the support rod 302d away from the chassis 302a. The second torsion spring 302c is arranged at one end of the support rod 302d. When the clamping block 302b is not rotated, the second torsion spring 302c is in its original state. When the chassis 302a moves downward with the descent of the push rod 201a-1, the support rod 302d also moves synchronously, and the clamping block 302b is pushed and rotated. At this time, the second torsion spring 302c is in a tense state. When the external force disappears, the second torsion spring 302c drives the clamping block 302b to return to its initial position.

[0049] Furthermore, the rotating member 301 includes a second gear 301a, a second rack 301b and a base 301c. The second rack 301b is installed on the top of the base 301c and is arranged corresponding to the second gear 301a. The base 301c is welded to the top of the outer side of the bracket 101. The second gear 301a is in contact with the second rack 301b, and the second gear 301a rotates and moves on the second rack 301b.

[0050] When in use, first pre-embed a steel plate above the concrete bottom plate of the caisson, weld the track to the pre-embedded steel plate, then weld the bottom of the bracket 101 to the track, and weld the reaction seat steel plate to the pre-embedded steel bars on the well wall. Workers place the pusher 102 on the bracket 101, fix the pusher 102 with the limit steel bars, and when the pusher 102 works, it will drive the bracket 101 to move. After the bracket 101 is installed, the welded steel pipe is then placed horizontally on the bracket 101. When the steel pipe descends, the bottom of the steel pipe will contact the load-bearing block 202a, and the load-bearing block 202a will descend due to gravity. Since the load-bearing block 202a is in contact and connected with the push block 202b, when the load-bearing block 202a descends, it will push the push block 202b to move to both sides, and the push block 202b is installed with a first rack 202c, and the first rack 202c moves with the push block 202b, and the first gear 203b follows the movement of the first rack 202c to rotate forward in the opposite direction. The first gear 203b is movably connected with the clamping jaw 201a through the moving rod 203a, and the moving rod 203a drives the clamping jaw 201a to move, thereby realizing the preliminary clamping of the steel pipe, and then through the limiting ring on the outer wall of the steel pipe, the steel pipe is fixed above the clamping piece 302 with steel bars passing through the limiting ring, thereby realizing the final fixation of the steel pipe.

[0051] When the steel pipe is not installed, the second gear 301a is in a locked state. At this time, the block 302b clamps the second gear 301a to prevent it from rotating. When the load-bearing block 202a is pressed down to a certain height by the steel pipe, the push rod 202a-1 also descends. Since the chassis 302a is installed at the bottom of the push rod 202a-1, the chassis 302a descends with the block 302b, and the block 302b rotates clockwise, so that the second gear 301a is unlocked. When the pushing member 102 is working, the second gear 301a can be pushed forward, step by step, and slowly inserted into the place where it needs to be inserted, reducing the workers' work content, improving efficiency, and reducing construction costs.

[0052] Example 3

[0053] Reference Figures 1 to 8 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0054] Specifically, the pushing member 102 includes a jack 102a and a support plate 102b. The jack 102a is installed at the top of the bracket 101, and the support plate 102b is welded to the top of the jack 102a. When the jack 102a works, the support plate 102b moves forward, and the support plate 102b is installed at the top of the bracket 101.

[0055] Furthermore, a slide groove 202b-1 is provided at the bottom of the push block 202b, and the slide groove 202b-1 contacts the protrusion on the movable plate 201f, that is, the push block 202b moves along the slide groove 202b-1 on the top of the movable plate 201f.

[0056] Furthermore, the number of the clamping jaws 201a is set to be multiple, and the clamping jaws 201a are arc-shaped and are correspondingly arranged at the top of the moving plate 201f.

[0057] Preferably, the number of the clamping jaws 201a is set to four, and the four clamping jaws 201a are set correspondingly.

[0058] Furthermore, one end of the jack 102a away from the abutment plate 102b is welded to the inner wall of the working well.

[0059] When in use, workers first embed steel plates above the concrete bottom plate of the caisson, weld the track to the embedded steel plates, then weld the bottom of the bracket 101 to the track, and weld the reaction seat steel plate to the embedded steel bars in the well wall. Workers place the jack 102a on the bracket 101, and then fix one end of the jack 102a with the limiting steel bars. When the jack 102a works, it will drive part of the bracket 101 to move. Since a steel pipe is provided on the bracket 101, the support plate 102b also moves against the steel pipe. Repeated operations of the jack 102a allow the steel pipe to be firmly inserted into the place where it needs to be inserted.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
