[0002] With the rapid development of my country's petroleum, chemical, nuclear power and other industries in recent years, some equipment has developed towards large-scale and giant development, which requires large-scale flipping and lifting equipment for lifting. The existing technology mainly uses two methods to achieve this. One is to use crawler cranes and main lifting equipment to complete the lifting operation, and the other is to use crawlers and main lifting equipment to complete the flipping operation.

[0003] As the weight and dimensions of the lifting equipment to be hoisted by the main lifting equipment continue to increase, the requirements for the flipping equipment continue to increase. The existing technology mainly has two problems:

[0004] 1. The crawler runs slowly, has low working efficiency, and requires high ground quality on site.

[0005] 2. Due to the variability of the center of gravity of the installation equipment, the center of gravity of different installation equipment is distributed differently relative to the main lifting and flipping equipment. As the weight increases, the skirt seat is prone to slip. Summary of the invention

[0006] The present invention mainly solves the above-mentioned technical problems and proposes a follow-up flipping device and a flipping hoisting method for hoisting equipment, which has the advantages of simple structure, high efficiency, good stability and greater safety.

[0011] A winch is arranged on one end of the rear flip support seat away from the front flip support seat, and the rope end of the winch is connected to one end of the flip platform close to the platform support seat.

[0012] Preferably, before the hoisting equipment is hoisted, the support shaft falls on the front flip support seat;

[0013] When the main lifting equipment is lifting the hoisting equipment, the hoisting equipment and the tilting platform tilt counterclockwise around the supporting point of the front tilting support seat, and the traveling chassis moves forward in coordination with the main lifting equipment;

[0015] During the lifting process, the rope of the winch does not provide power, and the rope is extended and retracted following the flip platform. After the flip is completed, the rope of the winch provides power and slowly releases the flip platform until the support shaft falls on the front flip support seat.

[0052] There are two front flip support seats 3, and the two front flip support seats 3 are correspondingly arranged at the front end of the walking chassis; the two front flip support seats 3 are respectively installed on the walking chassis by bolts, and the distance between the two front flip support seats 3 is adjustable.

[0053] There are two rear flip support seats 5, and the two rear flip support seats 5 are correspondingly arranged at the rear end of the walking chassis; the two rear flip support seats 5 are respectively installed on the walking chassis by bolts, and the distance between the two rear flip support seats 5 is adjustable.

[0054] Specifically, the front flip support seat 3 is installed on the front body 1 of the walking chassis by bolts, and the rear flip support seat 5 is installed on the rear body 8 of the walking chassis by bolts. The two groups of flip support seats can cooperate with different bolt mounting holes on the body to achieve spacing adjustment. Multiple groups of mounting holes are designed on the front and rear bodies, with a variety of options. The left and right distances of the two groups of flip support seats can be adjusted, and the spacing between the two groups of platform main beams 13 of the flip platform is adjusted at the same time. Secondly, different types of flip support seats can be replaced to meet the control of the center of mass position of different lifting equipment when using follow-up flip equipment for lifting.

[0055] The front flip support seat 3 and the rear flip support seat 5 are arranged on different horizontal planes. In this embodiment, the front flip support seat 3 and the rear flip support seat 5 have a certain height difference in their installation arrangement, so that the accompanying flip device of this embodiment can have no impact during the lifting and flipping process. The front flip support seat 3 and the rear flip support seat 5 can also be installed on other tracks, beams, and other walking mechanisms.

[0056] A winch 19 is arranged on the rear flip support seat 5 at one end away from the front flip support seat 3, and the rope end of the winch 19 is connected to one end of the flip platform close to the platform support seat 14. The winch 19 is specifically arranged between the power unit 6 and the rear flip support seat 5.

[0057] The flip platform includes: a lifting pressure rod 12 and two platform main beams 13 connected together; a platform support seat 14 is set at one end of the platform main beam 13, and a support shaft 11 is set at the other end; a lifting pressure rod 12 is set at the end of the platform main beam 13 close to the platform support seat 14; the support shaft 11 is set corresponding to the front flip support seat 3; the platform support seat 14 is set corresponding to the rear flip support seat 5.

Before lifting and flipping, the lifting equipment 17 is fixed on the flip platform by the lifting pressure rod 12 and the lifting bracket 16. During the flip lifting process, the lifting equipment 17 will not twist or slip. The support shaft 11 and the front flip support seat 3 are mutually fulcrums, and the platform support seat 14 and the rear flip support seat 5 are mutually fulcrums. The two sets of support points are of different heights, which effectively reduces the impact load brought by the lifting equipment during the flip lifting process, making the lifting more stable and reliable.

After the installation of the hoisting bracket 16 is completed, the hoisting pressure rod 12 slides relative to the pressure block through the pressure plate, so that the pressure block is stuck in the card slot at the tail of the hoisting equipment 17, the pressure plate is locked, and the hoisting pressure rod 12 and the hoisting bracket 16 form a four-point limiter to fix the hoisting equipment 17 on the flip platform, so as to prevent the hoisting equipment 17 from twisting, slipping, etc. during the hoisting process, and ensure that the center of mass position of the hoisting equipment remains unchanged.

[0060] The following flipping device for hoisting equipment in this embodiment cooperates with the main hoisting device 18 to complete the flipping and hoisting operation. The specific process is as follows:

[0061] Before the lifting device 17 is lifted, the lifting device 17 is in a horizontal position; the lifting device is used to flip the flip platform clockwise around the front flip support seat 3 to a vertical position, and the support shaft 11 of the flip platform falls on the front flip support seat 3. The lifting pressure rod 12 and the lifting bracket 16 fix the lifting device 17 to prevent twisting and deviation from the flip platform; the main lifting device 18 is lifted, and the main lifting device 18 lifts the lifting device 17. The lifting device 17 and the flip platform are flipped counterclockwise around the supporting point of the front flip support seat 3, and the walking chassis cooperates with the main lifting device 18 to move forward; in this process, the gravity of the lifting device 17 is transmitted to the front crawler chassis through the front flip support seat 3. As the main lifting device 18 is lifted, the flip platform The platform continues to flip, and the angle between the lifting equipment 17 and the ground gradually increases; when the flip platform flips to a certain angle, the support point of the flip platform switches back and forth, and the platform support seat 14 falls on the rear flip support seat 5, and the support shaft 11 is separated from the front flip support seat 3; the main lifting equipment 18 continues to lift, and the support shaft 11 rotates around the rear flip support seat 5, and the walking chassis continues to move forward until the angle between the lifting equipment and the ground is 90°, the flip is completed, the walking chassis stops moving, and the flip lifting is completed; during the lifting process, the rope of the winch 19 does not provide power, and follows the flip platform to retract the rope; after the flip is completed, the rope of the winch 19 provides power, and slowly releases the flip platform until the support shaft 11 falls on the front flip support seat 3.

[0062] Before the flip platform support point of the main lifting device 18 is switched during the lifting process, the overall center of mass of the flip platform and the lifting device 17 is always located on the right side of the front flip support seat 3. After the flip platform support point is switched to the rear flip support seat 5, during the continued flipping process, the overall center of mass of the flip platform and the lifting device 17 is always located on the right side of the rear flip support seat 5, that is, close to the side of the main lifting device 18, to prevent the skirt seat from slipping.
