[0056] The work of the main lifting mechanism is achieved;

[0057] Regarding the auxiliary lifting mechanism, please refer to Figure 3 , Figure 5 , including:

[0058] The double drum 101e, the rope 101c, and the transmission pulley 101d form a steel wire rope group for lifting and hoisting materials;

[0059] The hook 101f is installed on the rope body 101c and used for matching the steel wire rope group to complete the hoisting of the material;

[0060] The number of the rope body 101c is one, the transmission pulley 101d is arranged as five groups of ten, and the winding path of the steel wire rope group is as follows:

[0061] One group of the transmission pulley 101d is located on one side of the double drum 101e and in the same plane as the double drum 101e; the second group of the transmission pulley 101d is located in the middle of the double drum 101e and the first group of the transmission pulley 101d below the first group of the transmission pulley 101d; the third group of the transmission pulley 101d is located below the second group of the transmission pulley 101d; the fourth group of the transmission pulley 101d is located on one side of the third group of the transmission pulley 101d; and the fifth group of the transmission pulley 101d is located on one side of the double drum 101e close to the second group of the transmission pulley 101d;

[0062] Specifically, the first, second and fifth transmission pulleys 101d are fixed pulleys, the third and fourth transmission pulleys 101d are movable pulleys, and the hook 101f is installed on the third and fourth transmission pulleys 101d;

[0063] That is, one end of the rope body 101c is fixed to the outer wall of the double drum 101e, and the movable end passes through one of the first group of the transmission pulley 101d, one of the second group of the transmission pulley 101d, one of the third group of the transmission pulley 101d, one of the fourth group of the transmission pulley 101d, one of the fifth group of the transmission pulley 101d, the balance arm 202, the other of the fifth group of the transmission pulley 101d, the other of the fourth group of the transmission pulley 101d, the other of the third group of the transmission pulley 101d, the other of the second group of the transmission pulley 101d, the other of the first group of the transmission pulley 101d, and is fixed to the outer wall of the double drum 101e (on one side of the other end of the rope body 101c wound on the double drum 101e);

[0064] Different from the winding path of the main lifting mechanism, the double drum 101e, the rope body 101c and the balance arm 202 of the auxiliary lifting mechanism are all two, and the transmission pulley 101d is 20 corresponding to 10 groups, that is, the two winding paths overlap, and the rope body 101c of one auxiliary lifting mechanism is located outside the rope body 101c of the other auxiliary lifting mechanism;

[0066] In use, two double winding drums 101e rotate, since its one, its two, its four transmission pulleys 101d are fixed to rotate, when the double winding drum 101e winds the rope body 101c, based on the winding path, it can drive the third, fourth transmission pulleys 101d to move vertically, since the hook 101f is installed at the third, fourth transmission pulleys 101d, the lifting and hoisting of the material are completed;

[0067] Further comprising the anti-breaking rope assembly 101a arranged on the rope body 101c, the anti-breaking rope assembly 101a is derived from the prior art, in order to avoid the rope body 101c from breaking under heavy load and severe wear, affecting the production safety;

[0068] In actual use, please refer to Figures 2-7 , the staff assembles the main lifting mechanism and the auxiliary lifting mechanism to the rack, and installs the matched power source, installs the balance pulley 201 on the main lifting mechanism, installs the balance arm 202 on the auxiliary lifting mechanism, after assembly, the double winding drum 101e included in the main lifting mechanism and the two double winding drums 101e included in the auxiliary lifting mechanism are located on the rack, the main lifting mechanism;

[0069] Compared with the prior art, the winding balance of the steel wire rope can be kept in principle, and large errors can be avoided in the implementation process, and any double winding drum 101e adopts the mode of winding 2 steel wire ropes separately, so that the single steel wire rope is not too long, and adjustment is difficult in the super-high lift implementation mode;

[0070] And, the adjustment range of the balance pulley 201 and the balance arm 202 is greater than the manufacturing error of the winding drum rope groove;

[0071] Wherein, the above assembly operations are derived from the prior art, and the fixed mode, the rack, the power source and the type of the controller are not described in detail.

[0072] Please refer to Figure 3 , Figure 4 , Figure 8 , Figure 9 , as another embodiment of the utility model, a anti-rotation sleeve 101b for the rope body 101c of the lifting mechanism is provided, comprising:

[0073] The connecting head 101b-2 is arranged as a "U" type joint, and the number is two;

[0074] The two connecting heads 101b-2 are rotationally connected through the sleeve body 101b-1;

[0075] The screw rod 101b-3 penetrates through the connecting head 101b-2;

[0076] The nut 101b-4 is matched with the screw rod 101b-3, is located on the outer wall of the screw rod 101b-3 and is located on both sides of the connecting head 101b-2;

[0077] In use, the two ends of the disconnected rope body 101c are connected to the two connecting heads 101b-2 respectively, are clamped and fixed by the screw rod 101b-3 and the nut 101b-4 or are wound and fixed on the outer wall of the screw rod 101b-3. When the rope body 101c is twisted, since the two connecting heads 101b-2 are both rotationally connected with the sleeve body 101b-1, that is, the twisting stress of the rope body 101c can be released in a rotating manner;

[0078] In combination with the above embodiment, the user assembles the anti-rotation sleeve 101b to both sides of the balance pulley 201 and the balance arm 202, and can adjust the number and installation position of the anti-rotation sleeve 101b according to practical needs. Any anti-rotation sleeve 101b is installed at a position where the rope body 101c is prone to twist (for example, the twisting stress of the rope body 101c is not released by the release hook 101f), cooperates with the balance pulley 201 and the balance arm 202, can avoid the imbalance caused by the torsion of the steel wire rope due to the torsion of the steel wire rope in the process of lifting with super-high lift, reduces the workload of the user (the user releases and adjusts the torsion of the steel wire rope which has been twisted), and is convenient to use.

[0079] Based on the above structure, the problems of uneven winding length of the steel wire rope, difficulty in adjusting and twisting of the rope body 101c caused by the manufacturing error of the winding drum and the elongation of the steel wire rope in the process of lifting with super-high lift can be solved, and the stability, balance and safety in the process of lifting are improved.
