[0030] Example 1

[0031] like Figure 1 As shown, a multi-tube co-frame integral lifting device is composed of a base 1, a lifting platform 13 and a cooperative module 14;

[0032] The base 1 includes a leveling frame 2 and a segmented lifting vertical rail 6. The leveling frame 2 provides stable support for the segmented lifting vertical rail 6. The leveling frame 2 is the bearing foundation of the equipment, including an X support frame 21 and a Y support frame 22, and realizes stable support of the equipment through bidirectional telescopic adjustment.

[0033] like Figure 2As shown, the X support frame 21 is composed of two symmetrically arranged groups of first sleeve-type square steels 211, each group of first sleeve-type square steels 211 includes a first outer square steel 2111 and a first inner square steel 2112, and the first inner square steel 2112 is nested inside the first outer square steel 2111 and can be extended and retracted along the X direction to achieve adjustment of the support span in the X direction.

[0034] The Y support frame 22 is arranged perpendicular to the X support frame 21, and is composed of a second sleeve-type square steel 221, including a second outer square steel 2211 and a second inner square steel 2212. The second inner square steel 2212 is nested in the second outer square steel 2211 and can be extended and retracted along the Y direction to achieve adjustment of the support span in the Y direction.

[0035] Through holes 5 are provided on both the top and bottom surfaces of the X-support frame 21 and the Y-support frame 22. The terminal through hole 5 is used to secure the universal wheel 3, which has an integrated leveling knob 32 and a brake pedal 31. The leveling knob 32 allows for fine-tuning of the height, and the brake pedal 31 is used to lock the equipment after positioning. The remaining through holes 5 are used for securing the equipment during telescopic adjustment, ensuring a stable support span. Furthermore, the through holes 5 on the surface of the first sleeve-type square steel 211 are connected to a pipeline pulley assembly 4. This pulley assembly consists of a U-shaped bracket 42 and a ball bearing 41. The ball bearing 41 is mounted on the horizontal section of the U-shaped bracket 42, and the vertical section of the U-shaped bracket 42 is secured to the through holes 5 with bolts. The use of multiple pulley assemblies can reduce frictional resistance during pipeline transportation.

[0036] like Figure 3 As shown, the segmented vertical lifting rail 6 realizes multi-level adjustment of the lifting height and is composed of a basic vertical lifting rail 61, a secondary vertical lifting rail 62 and a motor 7. The specific structure is as follows:

[0037] The basic lifting vertical rail 61 is a rectangular steel structure, with a motor 7 base welded to the bottom for fixing the motor 7 with bolts; and a first pulley base welded to the top for fixing the first pulley 8 with a pin shaft.

[0038] The secondary lifting vertical rail 62 is a rectangular steel structure that matches the basic lifting vertical rail 61. It is nested inside the basic lifting vertical rail 61 and can slide along its inner wall. The second pulley 9 is fixed to the bottom of the secondary lifting vertical rail 62 by bolts, and the third pulley base is welded on the top and the third pulley 10 is fixed to achieve the extension of the lifting stroke.

[0039] like Figure 4As shown, the lifting platform 13 is used to carry and position multiple pipelines, and is composed of a load-bearing beam, a pipe-laying fork arm 133 and a connecting square steel 134. The load-bearing beam is slidably connected to the slide groove on the inner surface of the secondary lifting vertical rail 62 through the connecting blocks on both sides, and is composed of an upper beam 131 and a lower beam 132. Through holes 5 are provided on the side of both beams, and are fixed to the pipe-laying fork arm 133 by bolts; the base of the fourth pulley 11 is welded in the center of the top of the upper beam 131 and the fourth pulley 11 is fixed, and a level bubble 1311 is pasted on the side; the bottom of the lower beam 132 is fixed with bolts to an instability alarm device 1322, which triggers an audible and visual alarm and cuts off the power supply of the motor 7 when it is unstable.

[0040] The pipe-laying fork arm 133 is a Z-shaped sleeve-type square steel with 5 through holes on each side for adjusting the extension length of the fork arm; the top surface is laser-engraved with a measuring scale 1331 and is sleeved with a sliding block 1332. The bottom of the sliding block 1332 is provided with a fastening bolt, which can be tightened to fix its position, thereby achieving precise positioning of the horizontal spacing of the pipelines.

[0041] The connecting square steel 134 is a hollow square steel with through holes 5 at both ends. When two machines work together, it can be nested in the through holes 5 at the ends of the pipe-laying fork arms 133 of the two devices, and the two devices can be rigidly connected by fixing with bolts.

[0042] The collaborative module 14 is installed on the base 1 of the leveling frame 2 and consists of a synchronous controller, a wireless signal transceiver and a displacement sensor. The displacement sensors are installed on the load-bearing beams of the two devices respectively to monitor the lifting height in real time. The synchronous controller compares the height difference between the two devices and automatically adjusts the speed of the motor 7 when the difference exceeds 50mm to ensure synchronous lifting of the two machines.

[0043] Working principle:

[0044] First, push the equipment to the pipeline installation area, adjust the extension length of the X support frame 21 and the Y support frame 22 to expand the support area, turn the leveling knob 32 of the universal wheel 3 and observe the level bubble 1311 on the upper section of the load-bearing beam to make the equipment level, then step on the brake to lock it;

[0045] Then, according to the pipe assembly drawing, refer to the scale on the top surface of the pipe arrangement fork arm 133 to adjust the spacing between the sliding blocks 1332, and adjust the extension length of the fork arm through the side through hole 5; then use a multi-functional pipe transporter to transport the pipeline to the equipment, place one end of the pipeline on the pipeline pulley block 4 and push it until the pipe arrangement fork arm 133 is clamped between the sliding blocks 1332. Repeat the operation to place 3-6 pipelines and then secure them with pipe clamps;

[0046] Then, one end of the wire rope 12 is wound around the rotating end of the motor 7, and the other end passes through the first, second, third, and fourth pulleys in sequence and is fixed to the top of the secondary lifting vertical rail 62 to form a lifting circuit; after starting the motor 7, the load-bearing crossbeam first slides along the secondary lifting vertical rail 62, and after touching the top limit block, it drives the secondary lifting vertical rail 62 to slide along the basic lifting vertical rail 61. During the lifting process, the instability alarm device 1322 monitors the inclination angle in real time, and alarms and shuts down when it exceeds ±3°;

[0047] When the pipeline is raised to the designed elevation, the machine stops and locks itself. The operator installs the support bracket to fix the pipeline. After removing the pipe clamp, the motor 7 reverses to reset the lifting platform 13, releases the brake and moves the equipment to the next operation point to repeat the process.

[0048] Example 2

[0049] like Figure 5 As shown, when the multi-tube co-frame integral lifting equipment of the present invention is used with two machines, the two machines are arranged relative to each other, and the connecting square steel 134 is nested in the pipe fork arms 133 of the two devices to realize the connection between the two machines; the collaborative module 14 is started to ensure that the motors 7 of the two devices run synchronously. During the lifting process, the collaborative module 14 monitors the lifting status of the two machines in real time to ensure synchronization; the subsequent equipment adjustment, pipeline positioning, transportation, fixing, lifting and installation steps are consistent with single-machine operation.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
