[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] See also Figure 1-8 The utility model provides an auxiliary bracket for installing a large-diameter concrete pipe, comprising two sets of U-shaped frames 1 placed above a pipe 100 and two sets of oppositely arranged fixing seats 6. Both ends of the two sets of U-shaped frames 1 are fixedly connected to a base plate 2, the lower surface of the base plate 2 is fixedly connected to a base 21, and multiple sets of fixing holes 22 are formed through the base plate 2 and the base 21. The interior of the fixing holes 22 is movably connected to a ground nail 23. Adjustable wheel groups 3 are connected to the front and rear sides of the base 21 on the base plate 2. The inner sides of the two sets of U-shaped frames 1 are slidably connected to two sets of oppositely arranged L-shaped frames 4. The L-shaped frames 4 is provided with a driving member 5 for driving the L-shaped frame 4 to move, and a square plate 44 is fixedly connected to the lower end of the vertical side of the L-shaped frame 4. The fixing seat 6 is fixed to the side of the square plate 44 away from the L-shaped frame 4 by bolts. The front sides of the two groups of fixing seats 6 are fixedly connected to a placement seat 8 for placing pipe 2 200 through an arched connecting beam 7. The upper end of the placement seat 8 is fixedly connected to a guide plate 9, and the connection between the placement seat 8 and the guide plate 9 is fixedly connected to a connecting plate 93. The two groups of guide plates 9 are symmetrically distributed in an inverted eight shape, and the back sides of the placement seat 8 and the guide plate 9 are jointly fixedly connected with an inverted T-shaped frame 10.

[0029] The present invention provides two sets of guide plates 9 symmetrically distributed in the shape of an inverted eight. When hoisting the pipe 200, it is only necessary to hoist the pipe 200 to the inside of the two sets of guide plates 9. The guide plates 9 play a guiding and limiting role for the pipe 200. As the pipe 200 descends, it will gradually straighten and finally fall to the inside of the two sets of placement seats 8. At this time, the pipe 200 and the pipe 1 100 are aligned on the central axis. Under normal circumstances, construction workers do not need to hold the pipe 200 by hand, thereby reducing safety hazards and improving the safety of installation. Specific usage method: First, place the U-shaped frame 1 directly above the pipe 100, and then use the ground nails 23 to fix the base 21 to the ground. Then, the two sets of L-shaped frames 4 are driven to move closer to each other through the driving member 5. The L-shaped frame 4 drives the fixed seat 6 to move synchronously through the square plate 44 until the two sets of fixed seats 6 fit the outer wall of the pipe 100. Then, the placement seat 8 is connected and fixed to the fixing seat 6 through the arched connecting beam 7. After the fixing is completed, the second pipe 200 is hoisted to the inner side of the two sets of guide plates 9. After the guide plates 9 are aligned and guided, the second pipe 200 finally falls inside the two sets of placement seats 8. Finally, the second pipe 200 is pushed to fit the end of the first pipe 100.

[0030] It should be noted that the pipe 100 herein refers to the pipe that has been installed in place, and the pipe 200 refers to the pipe to be installed. During the installation process, the port of the pipe 200 needs to be aligned with the port of the pipe 100.

[0031] Furthermore, a C-shaped seat 12 is fixedly connected between the two groups of U-shaped frames 1, and the driving member 5 includes a double-threaded rod 51 and two groups of nut seats 52. The double-threaded rod 51 is rotatably connected to the inner side of the C-shaped seat 12, and the two groups of nut seats 52 are threadedly sleeved on the outer ends of the double-threaded rod 51. The lower surfaces of the two groups of nut seats 52 are fixedly connected to the upper surface of the horizontal edge of the L-shaped frame 4. The right end of the double-threaded rod 51 extends through to the outer side of the C-shaped seat 12 and is fixedly connected to the pulley 53.

[0032] Specifically, by rotating the wheel 53 , the double-threaded rod 51 can be driven to rotate, thereby driving the two groups of nut seats 52 to move in opposite directions, thereby driving the two groups of L-shaped frames 4 to move.

[0033] Furthermore, threaded holes 24 are provided on the front and rear sides of the surface of the base plate 2. The adjustable wheel group 3 includes an adjusting threaded rod 31 and a universal wheel 32. The adjusting threaded rod 31 is threadedly connected to the inside of the threaded hole 24. The universal wheel 32 is fixedly connected to the lower end of the adjusting threaded rod 31. The upper end of the adjusting threaded rod 31 is fixedly connected to an adjusting lever 33.

[0034] Specifically, the purpose of designing the adjustable wheel set 3 is to be able to be flexibly adjusted according to the specific needs of the construction site, so as to realize the movement of the entire device. When installing large-diameter concrete pipes, since the construction process needs to be carried out continuously, the device needs to be moved as a whole. In the non-moving state, the bottom height of the universal wheel 32 is higher than the bottom height of the base 21, so that the base 21 can be in full contact with the ground. When the device needs to be moved as a whole, the construction personnel only need to rotate the adjusting threaded rod 31 by adjusting the lever 33 to drive the universal wheel 32 to move downward until the bottom height of the universal wheel 32 is lowered below the bottom height of the base 21. At this time, the base 21 is separated from the ground, and the entire device can be moved by the universal wheel 32, which greatly improves the flexibility and efficiency of construction.

[0035] Furthermore, the front and rear sides of the transverse edges of the L-shaped frame 4 are fixedly connected to a connecting seat 41, the upper surface of the connecting seat 41 is fixedly connected to a supporting seat 42, the front and rear sides of the supporting seat 42 are rotatably connected to pulleys 43, and the transverse edges of the U-shaped frame 1 are provided with a sliding groove 11, and the pulley 43 is slidably connected to the inside of the sliding groove 11.

[0036] Specifically, when the L-shaped frame 4 moves, the pulley 43 is driven to slide in the slide groove 11 through the connecting seat 41 and the supporting seat 42, so that the L-shaped frame 4 slides more smoothly.

[0037] Furthermore, the front side of the fixing seat 6 is fixedly connected to the connecting buckle seat 1 61, the front and rear sides of the placement seat 8 are fixedly connected to the connecting buckle seat 2 81, the rear end of the arched connecting beam 7 is fixed to the connecting buckle seat 1 61 by bolts, and the front end of the arched connecting beam 7 is fixed to the connecting buckle seat 2 81 on the rear side of the placement seat 8 by bolts.

[0038] Specifically, the arched connecting beam 7 is used to connect the fixing seat 6 and the placement seat 8. It is fixed by bolts, which can achieve quick disassembly and assembly. When performing continuous installation of large-diameter concrete pipes, multiple sets of placement seats 8 can be connected in series through the arched connecting beam 7, thereby achieving continuous installation over a long distance without the need for frequent movement of the U-shaped frame 1, making installation more efficient.

[0039] Furthermore, an arcuate groove 82 is provided on one side of the placement seat 8 away from the inverted T-shaped frame 10 , and a plurality of sets of longitudinal roller frames 83 are fixedly connected to the surface of the arcuate groove 82 , and longitudinal rollers 84 are rotatably connected to the inner side of the longitudinal roller frames 83 .

[0040] Specifically, when the second pipe 200 is placed inside the arc-shaped grooves 82 of the two sets of placement seats 8, the second pipe 200 will contact the longitudinal rollers 84. The provision of the longitudinal rollers 84 allows the second pipe 200 to slide easily under the support of the longitudinal rollers 84, making it easier for construction workers to push the second pipe 200 toward the first pipe 100, thereby completing the jointing operation and greatly improving the convenience of the entire construction process.

[0041] Furthermore, a side of the guide plate 9 away from the inverted T-shaped frame 10 is fixedly connected to a plurality of transverse roller frames 91 , and the inner side of the transverse roller frames 91 is rotatably connected to transverse rollers 92 .

[0042] Specifically, during the process of hoisting Pipeline 200, when Pipeline 200 gradually descends and approaches the guide plate 9, its lower part will contact the transverse roller 92 on the guide plate 9. This contact causes the transverse roller 92 to start rolling, thereby effectively avoiding direct friction between Pipeline 200 and the guide plate 9. This not only reduces friction and potential damage to Pipeline 200, but also greatly improves the movement efficiency of Pipeline 200. With the smooth rolling of the transverse roller 92, Pipeline 200 can slide quickly and smoothly into place on the guide plate 9, making the hoisting process of Pipeline 200 more efficient and safe. In this way, construction personnel can more easily control the positioning of Pipeline 200, ensure its accurate placement, and thus lay a good foundation for subsequent connection and splicing operations.

[0043] Furthermore, two sets of moving wheels 1 85 are fixedly connected to the lower surface of the placement seat 8, two sets of connecting cylinders 102 are fixedly connected to the lower surface of the inverted T-shaped frame 10, the lower ends of the connecting cylinders 102 are fixedly connected to moving wheels 2 103, and the right-angled side of the inverted T-shaped frame 10 away from the placement seat 8 is fixedly connected to a diagonal brace 101.

[0044] Specifically, the first and second moving wheels 85 and 103 act as support. When the second pipe 200 is placed inside the two sets of placement seats 8, the first and second moving wheels 85 and 103 provide sufficient support for the second pipe 200, ensuring its stability throughout the installation process. Furthermore, when the entire device needs to be moved, the first and second moving wheels 85 and 103 can assist in movement.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
