Detailed implementation manners

[0033] The following further elaborates on the present application with reference to the accompanying drawings.

[0034] The embodiment of the present application discloses a container loading spreader. Referring to Figure 1 , it includes an upper horizontal rod 1 and a lower horizontal rod 4. The right end of the upper horizontal rod 1 is fixedly connected to the lower horizontal rod 4, and a U-shaped structure is formed between the right end of the upper horizontal rod 1 and the lower horizontal rod 4. A lifting lug 2 that can be adjusted to slide left and right is clamped on the upper surface of the upper horizontal rod 1, and an adjusting mechanism 3 for driving the left and right position adjustment of the lifting lug 2 is fixed near the right end of the upper horizontal rod 1. A detachable extension rod 5 is fixedly installed at the left end of the lower horizontal rod 4. When hoisting an item, the adjusting mechanism 3 drives the lifting lug 2 to move, thereby realizing the adjustment of the position of the lifting lug 2 on the upper horizontal rod 1, and then realizing the adjustment of the application point of the upward pulling force of the entire spreader, and further realizing the adjustment of the inclination angle of the lower horizontal rod 4, so that one end of the lower horizontal rod 4 can be better inserted into the inside of the item, and at the same time, it can also be better detached from the item after hoisting is completed, which can meet the adjustment requirements when hoisting different items. And by installing a detachable extension rod 5 at the left end of the lower horizontal rod 4, extension rods 5 of different lengths can be used according to the number of items hoisted at one time, so as to better meet the usage requirements of item hoisting, with good usage flexibility. A blocking block 6 is installed at the left end of the extension rod 5, and the hoisted item is limited and blocked by the blocking block 6 to prevent it from slipping. The blocking block 6 can be adjusted by rotation to block and unblock. When it is not necessary to use the blocking block 6 for blocking, the blocking block 6 is rotated so that its long end faces downward to release the blocking of the item for use.

[0035] Referring to Figure 2, a T-shaped block 22 is fixed to the lower end of the lifting lug 2, and a horizontally penetrating threaded hole 21 is opened at the center of the block 22. The lifting lug 2 is slidably clamped on the upper horizontal rod 1 through the block 22, so that the left-right movement adjustment can be carried out, and the movement drive can be realized by cooperating with the screw rod of the adjustment mechanism 3 through the opened threaded hole 21.

[0036] Refer to Figure 3 , the adjustment mechanism 3 includes a fixed block 32 fixed to the right end of the upper horizontal rod 1. A screw rod 31 is rotatably installed at the left end of the fixed block 32, and the screw rod 31 penetrates through the threaded hole 21. The fixed block 32 is used to rotatably support the right end of the screw rod 31. A motor 33 for driving the screw rod 31 to rotate is fixed to the right end of the fixed block 32, and the fixed block 32 is fixed to the upper horizontal rod 1 through a fixing screw 34. The motor 33 drives the screw rod 31 to rotate, and the rotating screw rod 31 drives the lifting lug 2 to slide left and right, so as to realize the adjustment of the inclination angle of the lower horizontal rod 4.

[0037] Refer to Figure 4 , an insertion block 321 is fixed to the left end of the fixed block 32. The fixed block 32 is positioned and inserted on the upper horizontal rod 1 through the insertion block 321. The fixed block 32 is positioned and installed by inserting the insertion block 321 into the guiding slot 12. And an installation plate 322 is fixed to the lower end of the fixed block 32. Installation holes for inserting the fixing screw 34 are opened on the installation plate 322, and the fixed block 32 is fixed to the upper horizontal rod 1 through the cooperation of the installation plate 322 and the fixing screw 34.

[0038] Refer to Figure 5 , a guiding slot 12 penetrating rightward is opened on the upper surface of the upper horizontal rod 1, and a fixed bearing 11 is installed on the left side wall of the left end of the guiding slot 12. The fixed bearing 11 fixes the left end of the screw rod 31, and thus also rotatably supports the left end of the screw rod 31. An installation slot 13 is opened at a position close to the right end of the upper horizontal rod 1. The upper horizontal rod 1 slidably clamps the lifting lug 2 through the guiding slot 12 and is used for the installation cooperation with the adjustment mechanism 3 through the installation slot 13.

[0039] Refer to Figure 5 , a jack 41 is opened at the left end of the lower horizontal rod 4, and a fixed threaded hole 42 is opened at the bottom of the hole at the right end of the jack 41 for thread fixing in cooperation with the fixed threaded head 54. The lower horizontal rod 4 inserts and installs the extension rod 5 through the jack 41, so as to stably support the extension rod 5 and is fixedly cooperated with the extension rod 5 through the fixed threaded hole 42.

[0040] Refer to Figure 6, a connecting threaded head 52 is fixed to the left end of the extension rod 5. The connecting threaded head 52 is used for threaded installation of the mounting sleeve 61. And a concave cavity is formed on the left end face of the connecting threaded head 52 for accommodating and giving way to the cylindrical stop head 62. A rubber sleeve 51 is fixed in the concave cavity. By sleeving the rubber sleeve 51 on the outside of the cylindrical stop head 62, damping during the rotation of the cylindrical stop head 62 is achieved, so as to realize the adjustment of the arbitrary rotation position of the blocking block 6. A plug rod 53 is fixed to the right end of the extension rod 5, and a fixed threaded head 54 is fixed to the right end of the plug rod 53. The extension rod 5 is installed on the lower horizontal rod 4 by inserting the plug rod 53, and is fixed after installation through the fixed threaded head 54.

[0041] Refer to Figure 7 , the blocking block 6 is arranged in an oblong shape, and a mounting sleeve 61 is arranged on the right side of the blocking block 6. The right side surface of the blocking block 6 is rotatably connected to the mounting sleeve 61 through a rotating shaft near the lower end. The blocking block 6 rotates around the rotating shaft. When the long end of the blocking block 6 turns to the upper end, it is higher than the upper surface of the extension rod 5 to block the items hung on the extension rod 5 and prevent them from slipping. The mounting sleeve 61 is threadedly sleeved on the connecting threaded head 52 to realize the installation and fixation of the blocking block 6 on the extension rod 5. A cylindrical stop head 62 is fixed to the right end of the rotating shaft. The cylindrical stop head 62 blocks the leftward movement of the rotating shaft to prevent the blocking block 6 from detaching from the mounting sleeve 61.

[0042] The implementation principle of an embodiment of the present application for a container loading spreader is as follows: When using the spreader to lift an item, the hook of the crane is hooked on the lifting lug 2. At this time, it moves to the item, and then the motor 33 drives the screw rod 31 to rotate. The rotating screw rod 31 drives the sliding adjustment of the lifting lug 2 to the right. At this time, the left end of the lower horizontal rod 4 moves downward, driving the lower horizontal rod 4 to start tilting. When the lower horizontal rod 4 is adjusted to a suitable state, the crane drives the left end of the lower horizontal rod 4 to move horizontally and insert it into the inside of the item. At this time, the crane starts to lift upward. At the same time, the motor 33 drives the screw rod 31 to rotate in the reverse direction. The reversely rotating screw rod 31 drives the sliding adjustment of the lifting lug 2 to the left until it moves to the leftmost end. Then the item is lifted and moved to the inside of the container and lowered to place the item at the bottom inside the container. At this time, the motor 33 is driven again to drive the screw rod 31 to rotate. The rotating screw rod 31 drives the sliding adjustment of the lifting lug 2 to the right. At this time, the lower horizontal rod 4 starts to tilt left and downward. Then the crane controls the spreader to disengage from the item. When there are more items lifted at one time, the plug rod 53 at one end of the extension rod 5 can be inserted into the jack of the lower horizontal rod 4 and fixed by screwing the fixed threaded head 54, so as to fixedly install the extension rod 5 and use the extension rod 5 to extend the length of the lower horizontal rod 4, so that more items can be lifted.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
