Description

Technical Field

[0001] The utility model relates to the technical field of hoisting structures, and specifically relates to a crane hoisting structure with multiple-point hooks. Background Art

[0002] Before the hoisting operation starts, a hoisting plan must be formulated. The key is to select appropriate hoisting points and hoisting tools. Reasonably arrange the construction site, determine the mechanical operation route and the component stacking location, lay the road and the mechanical operation track, measure the building axis and elevation, install the hoisting machinery, and prepare various rigging, lifting tools and tools. When building an offshore oil well platform, a hoist and a hoisting structure are required to lift the frame of the external hanging platform to the designated position, and then fix the frame of the external hanging platform to the oil well platform.

[0003] The existing Chinese utility model patent with the reference publication number of CN221253580U discloses a hoisting structure, which includes a third hoisting rope connected to the hook of a hoist. A hoisting pulley is connected to the third hoisting rope. A second hoisting rope is threaded through the hoisting pulley. Second shackles are provided at both ends of the second hoisting rope. A first hoisting rope is threaded through the second shackles. First shackles are provided at both ends of the first hoisting rope. It further includes a first lifting ring and a second lifting ring. The first lifting rings are all arranged at the top corners of the object; the second lifting rings are arranged on the sides along the length direction of the object; with this setting, by providing the first lifting ring and the second lifting ring at the top of the object to be hoisted, the number of common hoisting positions in the existing hoisting method can be increased from at least four to eight, and the total weight of the object can be effectively evenly distributed to each hoisting position; in this way, the force on each hoisting position is small, and the strength requirements for the lifting rings and the connection points of the lifting rings are small; more hoisting positions can also effectively reduce the bending deformation of the object during hoisting; at the same time, the used shackles have a small specification, a light weight, and are more convenient for hooking and unhooking.

[0004] In order to ensure that the outer expansion platform frame is in a horizontal state after being lifted, the hoisting points are generally arranged at equal angles outside the center of gravity of the frame. Although this method can make the object in a horizontal state after being lifted, it may cause the outer expansion platform frame to collide with other structures during the process of the hoist moving the outer expansion platform frame, and the existing hoisting structure cannot perform height fine-tuning according to the actual situation after moving the outer expansion platform frame to the designated area.

[0015] Compared with the prior art, the present utility model provides a hoisting structure of a multi-point hook crane, which has the following beneficial effects:

[0016] 1. Through the setting of the electric hoist in the present utility model, after connecting the load-bearing steel cable, the connecting steel cable, and the hook at the bottom end of the electric hoist on the right side of the connecting frame to the outer expansion platform frame, it is necessary to make the total length of the electric hoist above the synchronizing rod greater than the load-bearing steel cable, and then adjust the length of the electric hoist on the right side of the connecting frame so that the right end of the outer expansion platform frame is located directly below the center of the connecting frame when lifted, making the outer expansion platform frame as a whole in an inclined state, so that the frame, the load-bearing steel cable, the electric hoist on the right side of the connecting frame, and the connecting frame form an inverted isosceles triangle structure as a whole, thereby reducing the probability of the outer expansion platform frame colliding with surrounding objects when being lifted and moved.

[0031] Hook 19s are fixedly installed at the upper and lower ends of the load-bearing steel cable 110 and the lower end of the connecting steel cable 112. The load-bearing steel cable 110 is suspended below the connecting ring 13 at the bottom ends of the studs 16 at the front and rear ends on the left side of the connecting frame 15 through the hook 19 at the top end.

[0032] The front and rear ends of the synchronous rod 111 are fixedly connected to the movable ends of the electric hoists 18 at the centers of the front and rear ends of the connecting frame 15. The connecting steel cable 112 is symmetrically installed on the left and right sides of the front and rear ends of the synchronous rod 111 with the center of the synchronous rod 111 as the reference, both front and back and left and right.

[0034] In use, after connecting the load-bearing steel cable 110, the connecting steel cable 112, and the hook 19 at the bottom end of the electric hoist 18 on the right side of the connecting frame 15 to the outer expansion platform frame, it is necessary to make the total length of the electric hoist 18 above the synchronizing rod 111 greater than the load-bearing steel cable 110. Then, adjust the length of the electric hoist 18 on the right side of the connecting frame 15 so that the right end of the outer expansion platform frame is directly below the center of the connecting frame 15 when lifted, making the entire outer expansion platform frame in an inclined state, and causing the frame, the load-bearing steel cable 110, the electric hoist 18 on the right side of the connecting frame 15, and the connecting frame 15 to form an inverted isosceles triangle structure as a whole, thereby reducing the probability of the outer expansion platform frame colliding with surrounding objects when being lifted and moved. After lifting the object to the predetermined position, the length of the electric hoist 18 on the right side of the connecting frame 15 can be adjusted so that the length of the electric hoist 18 is equal to that of the load-bearing steel cable 110, and the outer expansion platform frame is adjusted from the inclined state to the horizontal state. The front and rear ends of the synchronizing rod 111 are fixedly connected to the movable ends of the electric hoists 18 at the centers of the front and rear ends of the connecting frame 15. After adjusting the frame to the horizontal state, the position of the synchronizing rod 111 can be adjusted by the electric hoist 18 above the synchronizing rod 111 so that the position of the hook 19 at the bottom end of the connecting steel cable 112 below the synchronizing rod 111 is higher than the hook 19 at the bottom end of the load-bearing steel cable 110.
