All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figures 1-4 The utility model provides a technical solution: a single-arm crane with high stability, the single-arm crane with high stability includes: an electric hoist 13, a storage box 18 is installed on the side wall of the electric hoist 13, a deep groove 19 is opened inside the storage box 18, a power motor 20 is installed inside the deep groove 19, a storage cylinder 21 is installed on the output end of the power motor 20, a rotating block 22 is installed on the side end of the storage cylinder 21, the rotating block 22 passes through the outer surface of the storage box 18, six limit rods 23 are installed on the outer surface of the rotating block 22 in an array, a windproof rope 27 is installed around the outer surface of the storage cylinder 21, and the outer end of the windproof rope 27 is fixed to the top of the hook 16;

[0027] The side wall of the storage box 18 is provided with a hole groove 24, which is located on the side of the rotating block 22. A screw rod 25 is installed inside the hole groove 24, and a clamping block 26 is installed on the outer surface of the screw rod 25.

[0028] During use, when the wind is strong, to prevent the hook 16 from shaking and causing items to fall, the power motor 20 drives the storage tube 21 to rotate, which facilitates the contraction of the windproof rope 27. The screw rod 25 drives the clamping block 26 to move in the hole groove 24 to a position close to the rotating block 22. At this time, the clamping block 26 is between the two limit rods 23, fixing the storage tube 21, and the retraction and extension length of the windproof rope 27 can be adjusted to tighten the hook 16. At the same time, when the single boom is not needed, it can also prevent the hook 16 from falling due to looseness, which may endanger the lives of on-site workers.

[0029] Example 2

[0030] On the basis of Example 1, in order to facilitate the movement of objects driven by a single boom, a rotating arm 6 is installed on the upper surface of the electric hoist 13, and a movable slot 12 is opened at the bottom of the rotating arm 6. The electric hoist 13 is located inside the movable slot 12, and a fixed pulley 14 is installed at the bottom of the electric hoist 13. A movable pulley 15 is installed at the bottom of the fixed pulley 14 through a rope. A hook 16 is installed at the bottom of the movable pulley 15, and a movable baffle 17 is installed at the opening of the hook 16. A fixed plate 8 is installed on the side wall of the rotating arm 6, and a cross bar 9 is installed at the center of the fixed plate 8. A plurality of sliders 10 are installed on the outer surface of the cross bar 9, and steel ropes 11 are installed between the sliders 10. A driving motor 7 is installed on the top of the rotating arm 6, and a steel rope 11 is connected to the outer surface of the output end of the driving motor 7. A rotating shaft 5 is installed at the bottom of the rotating arm 6, and a column 1 is installed at the bottom of the rotating shaft 5;

[0031] During use, the rotating arm 6 rotates under the action of the rotating shaft 5, which can facilitate the single boom to drive the objects to rotate and adjust the placement of the objects. The electric hoist 13 can be moved left and right on the movable slot 12 by driving the motor 7 to retract and release the steel rope 11, which is convenient for the use of the single boom. At the same time, by combining the fixed pulley 14 and the movable pulley 15, the power used by the electric hoist 13 can be saved to a great extent to drive the lifting of objects, thereby improving the utilization efficiency of the electric hoist 13.

[0032] Example 3

[0033] On the basis of the second embodiment, in order to provide better stability for the single boom, a placement plate 2 is installed on the outer surface of the column 1, a support frame 3 is installed on the top of the placement plate 2, the top of the support frame 3 is fixed to the bottom of the rotating arm 6, and a bearing 4 is installed inside the support frame 3. The bearing 4 is located on the outer surface of the column 1;

[0034] During use, in order to keep the rotating arm 6 more stable when transporting items, the bottom of both ends of the rotating arm 6 needs to be subjected to uniform force. Therefore, it is necessary to provide a balancing force to the end of the rotating arm 6 close to the column 1 through the support frame 3. At the same time, the bearing 4 facilitates the support frame 3 to move with the rotating arm 6 to avoid uneven force and reduce the stability of the single boom.

[0035] In actual use, the rotation of the rotating arm 6 under the action of the rotating shaft 5 can facilitate the single boom to drive the rotation of the objects and adjust the placement of the objects. The electric hoist 13 is moved left and right on the movable slot 12 by the driving motor 7 through the retracted and released steel rope 11, which is convenient for the use of the single boom. At the same time, the fixed pulley 14 and the movable pulley 15 are used in combination with each other, which can greatly save the power used by the electric hoist 13 to drive the lifting of objects and improve the efficiency of the electric hoist 13. In order to keep the rotating arm 6 more stable when transporting objects, it is necessary to make the bottom of both ends of the rotating arm 6 receive uniform force. Therefore, it is necessary to provide a flat surface for the rotating arm 6 near the end of the column 1 through the support frame 3. The bearing 4 facilitates the support frame 3 to move with the rotating arm 6 to avoid uneven force that reduces the stability of the single boom. When the wind is strong, the hook 16 is prevented from shaking and causing items to fall. The storage tube 21 is driven to rotate by the power motor 20, which facilitates the contraction of the windproof rope 27. The block 26 is driven by the screw rod 25 to move in the hole groove 24 to a position close to the rotating block 22. At this time, the block 26 is between the two limit rods 23, fixing the storage tube 21. The retraction and extension length of the windproof rope 27 can be adjusted, and the hook 16 is tightened. At the same time, when the single boom is not needed, the hook 16 can be prevented from falling due to looseness, which poses a life-threatening risk to on-site workers.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
