The plurality of supporting mechanisms 500 are disposed on the frame 300. And each supporting mechanism 500 is disposed corresponding to a connecting portion 20a. The support mechanism 500 can be switched between a support state and an avoidance state. In the supporting state, the supporting mechanism 500 is positioned below the connection portion 20a and supports the connection portion 20a during the lifting process of the frame 300 and the multi-section long-axis vertical device 20 positioned on the frame 300 from the horizontal state to the vertical state. In the avoidance state, the multi-section long axis vertical type device 20 can move in the length direction by the own lifting mechanism 400.
When the multi-section long axis vertical device special lifting tool 10 is used to lift the multi-section long axis vertical device 20, as shown in fig. 6, the supporting mechanism 500 may be first in an avoidance state, then the multi-section long axis vertical device 20 is placed on the frame 300, each connecting portion 20a of the multi-section long axis vertical device 20 is arranged corresponding to one supporting mechanism 500, then the supporting mechanism 500 may be switched from the avoidance state to the supporting state, and the self lifting mechanism 400 is connected with the multi-section long axis vertical device 20. Then, as shown in fig. 6 to 8, the frame 300 and the multi-section long axis vertical apparatus 20 positioned on the frame 300 may be turned from a horizontal state to an upright state by using the external crane mechanism 700, and the multi-section long axis vertical apparatus 20 in the upright state may be placed corresponding to the installation position. The external hoist mechanism 700 is then removed as shown in fig. 9. Finally, as shown in fig. 10 to 12, after all the supporting mechanisms 500 are switched from the supporting state to the avoiding state, the multi-section long-axis vertical device 20 can be lifted into the installation position by using the self-lifting mechanism 400.
When the special lifting tool 10 for the multi-section long-axis vertical equipment is used for lifting the multi-section long-axis vertical equipment 20, the plurality of bearing mechanisms 500 can provide multi-point support for the connecting part 20a of the multi-section long-axis vertical equipment 20 in the process of turning the multi-section long-axis vertical equipment 20 from a horizontal state to an upright state, reduce bending moment of the connecting part 20a of the multi-section long-axis vertical equipment 20, improve rigidity of the multi-section long-axis vertical equipment 20, effectively solve the problems that the air tightness, deformation, damage and the like of the equipment are easily damaged due to bending moment generated at the connecting part in the process of turning the multi-section long-axis vertical equipment 20 from the horizontal state in the lifting process, and ensure stability and reliability of the whole lifting process of the multi-section long-axis vertical equipment 20.
In this embodiment, the multi-section long axis vertical type equipment special lifting appliance 10 further comprises a lifting lug mechanism 600 arranged on the frame 300, so that the external crane mechanism 700 can turn the frame 300 from a horizontal state to a vertical state through the lifting lug. The lifting lug mechanism 600 is arranged, so that the external crane mechanism 700 is very convenient for lifting the frame 300 and the multi-section long-shaft vertical equipment 20 positioned on the frame 300. It will be appreciated that in other embodiments, the shackle mechanism 600 may be omitted when the outboard crane mechanism 700 may be directly coupled to the frame 300.
In this embodiment, the shackle mechanism 600 includes a primary shackle 610 provided at one end of the frame 300 near the self-lifting mechanism 400 and a secondary shackle 620 provided at the middle of the frame 300. In this manner, the frame 300 and the multi-section long axis vertical apparatus 20 located on the frame 300 may be turned from the horizontal state to the vertical state by the connection of the main hoist mechanism 710 of the outboard hoist mechanism 700 with the main lifting lug 610 and the connection of the secondary hoist mechanism 720 of the outboard hoist mechanism 700 with the secondary lifting lug 620. Specifically, during the lifting process, the main sling 712 is lifted by the main crane mechanism 710, the auxiliary sling 722 is delivered forward by the auxiliary crane mechanism 720 (the main sling 712 is lifted higher than the auxiliary sling 722 to maintain the suspended state of the frame 300 and the multi-section long-axis vertical apparatus 20), and the frame 300 and the multi-section long-axis vertical apparatus 20 are gradually turned over in the air, so that the turning-over and standing actions are completed.
Specifically, in the present embodiment, the main lifting lug 610 and the sub lifting lug 620 are both spool lifting lugs. In this manner, the primary lifting lug 610 and the secondary lifting lug 620 are conveniently connected to the crane mechanism 700, and it is understood that in other embodiments, the primary lifting lug 610 and the secondary lifting lug 620 may be other types of lifting lugs and may be connected to the crane mechanism 700.
In this embodiment, the frame 300 includes a frame 310 and a beam 320 disposed on a side of the frame 310 away from the support mechanism 500. The frame 310 includes two main beams 312 on either side. The main beams 312 extend along the length of the multi-section long axis vertical apparatus 20. The number of beams 320 is plural. The plurality of cross beams 320 are arranged at intervals along the length direction of the multi-section long-axis vertical device 20, and each cross beam 320 is connected with two main beams 312. In this way, the frame 300 can have a superior structural strength.
In this embodiment, two sides of the supporting mechanism 500 are respectively connected to two main beams 312. The main lifting lug 610 is provided at an end of the main beam 312 adjacent to the self-contained lifting mechanism 400. The secondary lifting lug 620 is provided in the middle of the main beam 312.
In this embodiment, the beam 320 is U-like. In this way, the frame 300 may be made to have better structural strength. Specifically, in the present embodiment, the cross member 320 includes a cross member 322 parallel to the frame 310 and two diagonal members 324 disposed on both sides of the cross member 322. Diagonal rods 324 connect the main beams 312 with the cross bars 322.
In the present embodiment, the self-lifting mechanism 400 includes a hoist 410 and a boom 420 provided at one end of the frame 300, a guide wheel 430 provided on the boom 420, and a self-lifting rope 440 wound around the hoist 410. The sling 440 is adapted to be coupled to the multi-section long axis vertical device 20 after being wound around the guide wheel 430. In this way, the self-lifting mechanism 400 is very convenient to connect with one end of the multi-section long-axis vertical device 20.
In this embodiment, the support mechanism 500 includes two support clips 510. Two support clips 510 are located on either side of the body section 20b. And the support clip 510 can move toward or away from the shaft section 20b. When the supporting mechanism 500 is switched from the supporting state to the avoiding state, the two supporting clips 510 move away from the joint body 20b at the same time. When the support mechanism 500 is switched from the avoidance state to the support state, the two support clips 510 move closer to the joint body 20b at the same time. In this way, it is very convenient to realize that the supporting mechanism 500 has a supporting state and an avoiding state, and at the same time, it is very convenient to realize that the supporting mechanism 500 is switched from the supporting state to the avoiding state. It will be appreciated that in other embodiments, the support mechanism 500 may be a telescopic structure, in which the support mechanism 500 is extended in the support state and the support mechanism 500 is retracted in the avoidance state.
In this embodiment, the support clip 510 has a semi-arcuate shape. In this embodiment, the movement of the support clip 510 toward or away from the shaft section 20b can be achieved by means of an electrically controlled manner.
In this embodiment, the support mechanism 500 further includes a movable bracket 520. Both sides of the movable bracket 520 located at the body-saving portion 20b are respectively connected to the frame 300. Specifically, two sides of the movable bracket 520 are respectively connected to the two main beams 312. Two support clips 510 are provided on the movable bracket 520. In this manner, the support clip 510 is conveniently and indirectly mounted to the frame 300. It will be appreciated that in other embodiments, the support clip 510 may be mounted directly to the frame 300, and the movable bracket 520 may be omitted.
In this embodiment, the support mechanism 500 is capable of moving on the frame 300 along the length of the multi-section long axis vertical apparatus 20. Thus, the distance between two adjacent connecting portions 20a of the multi-section long-axis vertical apparatus 20 with different model sizes may be different, and each supporting mechanism 500 can be correspondingly arranged with one connecting portion 20a by adjusting the supporting mechanism 500 to move on the frame 300 along the length direction of the multi-section long-axis vertical apparatus 20. Therefore, the special lifting appliance 10 for the multi-section long-axis vertical equipment can be suitable for lifting multi-section long-axis vertical equipment 20 with different model sizes. It will be appreciated that in other embodiments, the position of the support mechanism 500 in the frame 300 may be fixed and correspond to the position of the connecting portion 20a of the multi-section long axis vertical device 20 with a certain model size.
In this embodiment, the support mechanism 500 is slidably connected to the frame 300 through the slide rails 800 on both sides of the body section 20b. Specifically, in the present embodiment, the movable bracket 520 is slidably connected to the frame 300 through the slide rails 800 on both sides of the section 20b. In this way, it is very convenient to implement the support mechanism 500 to move on the frame 300 along the length direction of the multi-section long axis vertical type device 20.
In this embodiment, the plurality of holding mechanisms 500 can move toward the self-elevating mechanism 400 or away from the self-elevating mechanism 400 on the frame 300 along the length direction of the multi-section long-axis vertical apparatus 20 at the same time. When the multi-section long-axis vertical apparatus 20 is in the upright state, the self-lifting mechanism 400 is located at the upper end of the frame 300, and at this time, the plurality of bearing mechanisms 500 can move downward or upward on the frame 300 along the length direction of the multi-section long-axis vertical apparatus 20. The end of the frame 300 away from the self-elevating mechanism 400 has a stopping area 300a, and when the supporting mechanism 500 reaches the stopping area 300a, the supporting mechanism 500 in the stopping area 300a stops moving toward the self-elevating mechanism 400 or away from the self-elevating mechanism 400 along the length direction of the multi-section long-axis vertical apparatus 20. In this way, when the multi-section long-axis vertical device 20 is lifted into the installation position by the self-lifting mechanism 400 after all the supporting mechanisms 500 are switched from the supporting state to the avoiding state, the self-lifting mechanism 400 is very convenient to stably lift the multi-section long-axis vertical device 20 into the installation position.
Specifically, at this time, as shown in fig. 9, the external crane mechanism 700 holds the frame 300 and the multi-section long axis vertical apparatus 20 on the frame 300 in an erected state, and places the multi-section long axis vertical apparatus 20 in the erected state in correspondence with the installation position. At this time, all the supporting mechanisms 500 can be controlled to move downwards, meanwhile, the self-lifting mechanism 400 controls the multi-section long-shaft vertical device 20 to move downwards correspondingly, and after the supporting mechanism 500 at the first bottom end reaches the stop area 300a, the supporting mechanism 500 at the first bottom end stops moving downwards, and at this time, the supporting mechanism 500 at the first bottom end can be switched from a supporting state to an avoiding state, so that the multi-section long-shaft vertical device 20 continues to move downwards; as shown in fig. 10, after the second bottom end supporting mechanism 500 reaches the stop area 300a, the second bottom end supporting mechanism 500 stops moving downward, and at this time, the second bottom end supporting mechanism 500 may be switched from the supporting state to the avoiding state, so that the multi-joint long-axis vertical device 20 continues to move downward; as shown in fig. 11, after the third bottom end supporting mechanism 500 reaches the stop area 300a, the third bottom end supporting mechanism 500 stops moving downward, and at this time, the third bottom end supporting mechanism 500 may be switched from the supporting state to the avoiding state, so that the multi-joint long-axis vertical device 20 continues to move downward; as shown in fig. 12, after the fourth bottom end supporting mechanism 500 reaches the stop area 300a, the fourth bottom end supporting mechanism 500 stops moving downward, and at this time, the fourth bottom end supporting mechanism 500 may be switched from the supporting state to the avoiding state, so that the multi-joint long axis vertical apparatus 20 continues to move downward. When the plurality of bearing mechanisms 500 move to the stop region 300a in sequence and all the bearing mechanisms 500 are in the avoiding state, the multi-section long-axis vertical device 20 is lifted into the installation position by the self-lifting mechanism 400.
