The beneficial effects are as follows:

[0014] 1. Improve construction efficiency and realize rapid relay transportation:

[0015] 1. Collaborative operation of multiple devices: By deploying three devices at both ends and the middle of the pipe pile, using the head-up structure to lift one end of the pipe pile, the supporting structure to lift it twice, and the auxiliary components to bear horizontally, a relay-type conveying mode is formed. Compared with the traditional single-device hoisting process that requires frequent disassembly of the hoisting equipment and binding of steel ropes, this device can move forward through alternating support of the equipment, greatly reducing the waiting time of the hoisting equipment and significantly improving the efficiency of the assembly line operation;

[0016] 2. Labor-saving drive design: The drive assembly adopts worm, turbine, and gear meshing transmission (such as the diameter difference between the first driving wheel and the first driven wheel to achieve labor-saving transmission). The lifting and lowering of the head structure and the lifting of the supporting structure can be achieved through the manual rocker. It is easy to operate and does not rely on large machinery. It can adapt to the complex environment of the construction site and shorten the single operation time.

[0017] 2. Reduce manual intervention and reduce operational risks:

[0018] 1. Mechanization replaces manual operation: In traditional construction, it is necessary to manually tie steel ropes and adjust the position of pipe piles, which may cause safety hazards such as steel rope breakage and pipe pile collision. This device directly contacts the pipe piles through structures such as lifting forks, guide rollers, and conveyor rollers to achieve mechanized lifting and movement, avoid close-range manual operation, and reduce the risks of falling from heights and being hit by objects.

[0019] 2. Stable support and guidance: The lifting fork of the head-lifting structure and the guide roller of the supporting structure can firmly support the pipe pile and reduce shaking; the conveying roller of the auxiliary component adopts rolling friction instead of sliding friction to reduce the movement resistance of the pipe pile and avoid damage or position displacement of the pipe pile caused by ground friction.

[0020] 3. Enhance operational safety and equipment adaptability:

[0021] 1. Structural stability design: The main component adopts a multi-point support structure of the first frame, wheel arm, and universal wheel, combined with the rigid connection between the Y-shaped first axis arm and the sleeve rod to ensure the stability of the equipment when carrying pipe piles and avoid tilting or overturning due to uneven ground (such as the risk of collapse in karst areas).

[0022] 2. Removable and adjustable function: The auxiliary components can be quickly installed / disassembled by inserting the pillars into the wheel arm sockets to meet the needs of different construction scenarios; the top height bolts of the support structure can adjust the tilt angle of the support arm, and the guide roller height can flexibly adapt to different diameters of pipe piles as the lifting arm moves, thereby improving the versatility of the device.

[0023] 3. Improve construction flexibility: For complex landforms such as karst areas, the cooperation between the universal wheel and the conveyor roller of the auxiliary component can realize the stable movement of pipe piles on uneven ground; the multi-stage lifting of the lifting structure (one lifting of the head structure and the second lifting of the supporting structure) makes it easier for pipe piles to cross surface obstacles (such as karst gullies and stone buds), solving the problem of difficult binding of steel ropes and difficult movement of pipe piles due to uneven surface caused by traditional equipment.

[0024] In summary, the present invention realizes the efficiency, safety and low cost of pipe pile construction through the integrated design of mechanical lifting, relay transportation and flexible support. It is particularly suitable for complex geological conditions such as karst areas, and provides an innovative solution for the construction of large-diameter pipe piles. It has significant engineering application value and economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] As a preferred solution, further, as Figure 4 and Figure 5As shown in the figure, the supporting structure 4 includes a first shaft seat 41, a driving screw 42, a third rocker 43, a second driven wheel 44, a second driving wheel 45, a pair of lifting arms 46, a pair of jacking bolts 47, a pair of support arms 48 and a pair of guide rollers 49; the first shaft seat 41 is concave, and both ends of the first shaft seat 41 are fixedly sleeved on the sleeve rod 15 respectively, and the middle part of the first shaft seat 41 is located on the right side of the driving box 21.

A pair of jacking bolts 47 are respectively movably screwed on the other ends of the lifting arms 46. One ends of a pair of support arms 48 are respectively movably arranged on the other ends of the lifting arms 46, and the support arms 48 are located above the jacking bolts 47. A pair of guide rollers 49 are respectively movably arranged on the other ends of the support arms 48 and are symmetrical to each other. By driving the second driving wheel 45 to rotate through the third rocker 43, the second driven wheel 44 is driven to drive the driving screw 42 to rotate on the first shaft seat 41, and then the two lifting arms 46 are driven to move relatively, so that the pipe pile can be forced to be supported and lifted upward by means of the guide rollers 49 on the support arms 48. The guide rollers 49 are located on both sides of the lifting fork 38, and the guide rollers 49 can be located above the first shaft arm 14 for supporting and lifting requirements, so that the auxiliary assembly 5 can be installed under the pipe pile.

[0041] As a preferred solution, further, as Figure 6 shown, the auxiliary assembly 5 includes two pairs of support columns 51, a lifting plate 52 and a plurality of conveying rollers 53; one ends of the two pairs of support columns 51 are respectively detachably inserted into the jacks 7 of the wheel arms 12. The lifting plate 52 is fixedly arranged between the tops of the two pairs of support columns 51, and the lifting plate 52 is located above the first shaft arm 14. A plurality of conveying rollers 53 are respectively equidistantly embedded in the lifting plate 52; by detachably installing the support columns 51 on the wheel arms 12, the pipe pile can be moved by means of the conveying rollers 53 on the lifting plate 52 for loading.

[0042] Working principle:

[0043] S1. The equipment can be moved through the universal wheels 13 under the lower wall of the first vehicle frame 11 and under the wheel arms 12 in the main body assembly 1, and the handrail 16 on the first shaft arm 14 can be used for exerting force.

[0044] S2. When the pipe pile is moved and conveyed through the equipment, three equipment can be used in combination. Two of the equipment are arranged at both ends of the pipe pile, and the other is arranged in the middle of the pipe pile.

[0045] S3. For example: Move the device to make the wheel arms 12 located on both sides of one end of the pipe pile, and attach the lifting forks 38 on the insertion arms 37 in the lifting structure 3 to the middle of the bottom of one end of the pipe pile; then drive the moving seat 36 to move within the cross-shaped seat 34 by shaking the second rocker 35, and insert the lifting fork 38 at one end of the insertion arm 37 into the bottom of the pipe pile;

[0046] Then shake the first rocker 26 to drive the first driving wheel 27 to rotate on the first wheel frame 25. Drive the large-diameter first driven wheel 24 to rotate through the small-diameter first driving wheel 27, realizing labor-saving drive for the worm 22 to rotate. And when the worm 22 rotates between the first shaft arms 14, it will drive the turbine 23 located within the drive assembly 2. Since the turbine 23 is screwed to the lead screw 31, and the lead screw 31 is limited by the two lifting rods 33 between the first mounting plate 32 and the cross-shaped seat 34 and cannot be driven by the turbine 23 to rotate, the turbine 23 will drive the lead screw 31 to move up and down under force through the limited rotation of the drive box 21, prompting the lead screw 31 to rise and drive the lifting fork 38 on the cross-shaped seat 34 to rise, thus lifting one end of the pipe pile;

[0047] S4. Similar to the operation in S3 above, after lifting both ends of the pipe pile, use the universal wheels 13 to convey the pipe pile or it is convenient to tie the steel rope after lifting one end of the pipe pile;

[0048] Or after lifting both ends of the pipe pile, shake the third rocker 43 in the supporting structure 4. After driving the second driving wheel 45 to rotate and driving the second driven wheel 44 to rotate through the third rocker 43, realize labor-saving drive for the drive screw 42 to rotate on the first shaft seat 41. Through the limitation of the first shaft seat 41, the two lifting arms 46 are limited and move relatively under the rotation of the drive screw 42, prompting the guide rollers 49 on the support arms 48 to move relatively and contact the side wall below the middle of one end of the pipe pile. Since the support arms 48 can be jacked up by rotating the top height bolts 47, the support arms 48 are relatively inclined; then as the support arms 48 move relatively and apply force to the pipe pile and through the rotation of the guide rollers 49, the pipe pile is forced to rise again, and the lower wall of the pipe pile is located above the sleeve rod 15;

[0049] At this time, the auxiliary assembly 5 can be placed at the jacking holes 7 of the two wheel arms 12, insert the support column 51 into the jacking hole 7 to install the lifting plate 52, contact the pipe pile through the conveying rollers 53 on the lifting plate 52, and after loosening and resetting the support arms 48 and the guide rollers 49, the pipe pile can be pushed to move on the conveying rollers 53 by the force on the conveying rollers 53 corresponding to the axis of the pipe pile, preventing the movement of the universal wheels 13 from being affected by the terrain.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any other modifications or functional substitutions made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
