[0040] In the embodiment of the present invention, the partition baffle 11 is used to separate the interior of the square lifting beam 1 into two independent spaces, thereby facilitating the separate adjustment of the upper lifting rope 28 and the lower lifting rope 37. On the other hand, the square lifting beam 1 can be structurally strengthened to ensure its strength.

[0041] In the embodiment of the present invention, the square hoisting beam 1 can be suspended between the hook and the hoisting member by utilizing its own structure, thereby ensuring that the hoisting member can be hoisted stably and avoiding tilting.

[0042] The adjusting upper lifting rope mechanism 2 is arranged in the upper space inside the square lifting beam 1, and includes: an upper end block 21, which is installed at both ends inside the square lifting beam 1; an upper center end block 22, which is installed at the center inside the square lifting beam 1; an upper lifting slide rod 23, which is installed between the upper end block 21 and the upper center end block 22, and is located on both sides of the upper space inside the square lifting beam 1; an upper lifting screw 24, which is located at the center of the upper space inside the square lifting beam 1, is a double-headed screw with positive and negative threads, and is installed between the two upper end blocks 21, and is connected to the upper center end block 22 through a bearing, one end of which extends out of the square lifting beam 1, and is installed with an upper lifting handle 241.

[0043] In the embodiment of the present invention, the upper end block 21 and the upper center end block 22 are arranged to strengthen the upper ends of the square lifting beam 1. At the same time, in order to ensure its installation strength, the square lifting beam 1 and the upper end block 21 and the upper center end block 22 can be reinforced and fixed with pins to ensure their connection strength.

[0044] In the embodiment of the present invention, the upper hoisting slide bar 23 is provided to strengthen the strength of the square hoisting beam 1 while facilitating the sliding of the inverted T-shaped adjustment seat 27 to ensure the stability of the hoisting.

[0045] In the embodiment of the present invention, by utilizing the setting of the upper lifting screw 24 and its own double-headed screw with positive and negative threads, the two inverted T-shaped adjustment seats 27 on both sides above the square lifting beam 1 can be synchronously moved closer to or away from the center of the square lifting beam 1, thereby ensuring the symmetry of the adjustment and enabling the device to maintain stable lifting during use.

[0046] The adjusting port 25 is opened on both sides of the center of the upper surface of the square lifting beam 1 and is located between the upper end block 21 and the upper center end block 22; the reinforcing baffle 26 is arranged on both sides of the upper surface of the square lifting beam 1, and a plurality of gussets 261 are installed on one side thereof, and the gussets 261 are located on both sides of the adjusting port 25; the inverted T-shaped adjusting seat 27 is slidably installed in the upper space of the square lifting beam 1, and is slidably sleeved on the upper lifting slide rod 23, and is threadedly connected to the upper lifting screw 24, the upper end of which extends out of the adjusting port 25, and an adjusting groove 271 is opened at the center, and the upper lifting wire rope pulley 272 is installed in the adjusting groove 271; the upper lifting rope 28 is arranged above the square lifting beam 1, and its two ends are fixedly connected to the upper end block 21 and sleeved on the upper lifting wire rope pulley 272.

[0047] In the embodiment of the present invention, the setting of the adjustment port 25 can facilitate the installation of the upper hanging rope 28. At the same time, the setting of the gusset plate 261 can ensure the strength of the panels on both sides of the adjustment port 25, thereby ensuring that the inverted T-shaped adjustment seat 27 can slide stably and avoid deformation of the device.

[0048] In the embodiment of the present invention, the movement of the inverted T-shaped adjustment seat 27 can be used to control the extension length of the upper hanging rope 28, thereby controlling the distance between the square lifting beam 1 and the hook and reducing the lifting height of the special hanger.

[0049] In the embodiment of the present invention, the upper hanging rope 28 is provided with both ends mounted on the upper end block 21, which can ensure the stability of the force applied to the upper hanging rope 28 and facilitate the quick connection between the square hoisting beam 1 and the hook.

[0050] The adjusting lower lifting rope mechanism 3 is arranged in the lower space inside the square lifting beam 1, and includes: a lower end block 31, which is installed at both ends inside the square lifting beam 1; a lower center end block 32, which is installed at the center inside the square lifting beam 1; a lower lifting slide rod 33, which is vertically and parallelly arranged between the lower end block 31 and the lower center end block 32, and is located on both sides of the lower space inside the square lifting beam 1; a lower lifting screw 34, which is located at the center of the lower space inside the square lifting beam 1, is a double-headed screw with positive and negative threads, and is installed between the two lower end blocks 31, and is connected to the lower center end block 32 through a bearing, one end of which extends out of the square lifting beam 1, and is installed with a lower lifting handle 341.

[0051] In the embodiment of the present utility model, by setting the lower end block 31 and the lower center end block 32, the spatial structure below the square lifting beam 1 can be strengthened to ensure its strength. At the same time, a pin can also be used for strengthening and fixing to ensure its connection strength, making the connection of the lower lifting rope 37 more firm.

[0052] In the embodiment of the present utility model, by setting the lower lifting slide rod 33, on the one hand, the strength of the square lifting beam 1 can be strengthened, and on the other hand, the sliding of the square adjusting seat 35 can be made more stable.

[0053] In the embodiment of the present utility model, by setting the lower lifting screw rod 34 and using its own double-headed screw with reverse and forward threads, the two lower lifting ropes 37 can be adjusted simultaneously, thereby ensuring the stability of the lifting piece during the lifting process.

[0054] The square adjusting seat 35 is slidably installed in the lower space of the square lifting beam 1, slidably sleeved on the lower lifting slide rod 33, and threadedly connected to the lower lifting screw rod 34. Horizontal grooves 351 are formed on both sides of the center thereof, and the first lower lifting wire rope pulley 352 is installed in the horizontal grooves 351; the U-shaped support seat 36 is installed at the four corners of the lower surface of the square lifting beam 1. The two ends thereof are L-shaped. The second lower lifting wire rope pulley 361 is installed inside it. Angle brace plates two 362 are provided on both sides of the outside thereof. The angle brace plates two 362 are installed in the L-shaped of the two ends and fixedly connected to the square lifting beam 1; the lower lifting rope 37 is provided at both ends below the square lifting beam 1. The two ends thereof are inserted into the square lifting beam 1 through the U-shaped support seat 36, sleeved on the first lower lifting wire rope pulley 352 and the second lower lifting wire rope pulley 361, and fixedly connected to the lower end block 31.

[0055] In the embodiment of the present utility model, by setting the square adjusting seat 35 and using the first lower lifting wire rope pulley 352 in the two horizontal grooves 351, the lower lifting rope 37 can be adjusted by its movement inside the square lifting beam 1, so as to control the height between the lifting piece and the square lifting beam 1, and further reduce the lifting height of the special lifting frame.

[0056] In the embodiment of the present utility model, by the self-shape of the U-shaped support seat 36, the installation and adjustment of the lower lifting rope 37 can be facilitated. By using the second lower lifting wire rope pulley 361 of the lower lifting rope, the service life of the lower lifting rope 37 can be ensured. By the L-shaped of both sides of the U-shaped support seat 36, the device can be stably placed on the ground, facilitating the storage of the square lifting beam 1. At the same time, by setting the angle brace plates two 362, the connection stability between the U-shaped support seat 36 and the square lifting beam 1 can be ensured.

[0057] In the present invention, the distance between the two upper hoisting wire rope pulleys 272 is half the length of the upper hoisting rope 28 between the two upper hoisting wire rope pulleys 272; by utilizing the synchronous movement of the two inverted T-shaped adjustment seats 27, the upper hoisting rope 28 can be made to present a 60° angle during hoisting, thereby ensuring the safety of the upper hoisting rope 28 while ensuring the stability of the hoisting.

[0058] In the present invention, the lower hanging rope 37 is U-shaped at both ends below the square hanging beam 1 , which can facilitate the quick connection between the hanging part and the lower hanging rope 37 .

[0059] In the present invention, the lower hoisting wire rope pulley 352 in the horizontal groove 351 is horizontally arranged, and the horizontal groove 351 is located between the lower hoisting screw rod 34 and the lower hoisting slide rod 33; it is convenient to adjust the lower hoisting rope 37.

[0060] When using the utility model, first, the worker moves the hook to the top of the square hoisting beam 1, then the worker manually hangs the upper hoisting rope 28 on the hook, and then uses the hook to drive the hoisting of the upper hoisting rope 28, so that the square hoisting beam 1 moves with the hook to the top of the hoisting member;

[0061] Then, the staff simply visually checks the distance between the lifting piece and the square lifting beam 1, as well as the distance between the hook and the square lifting beam 1, based on the lifting requirements of the actual location;

[0062] Subsequently, the staff manually rotates the upper lifting handle 241, and then uses the rotation of the upper lifting screw 24 to synchronously move the two inverted T-shaped adjustment seats 27 closer to or farther from the center of the square lifting beam 1, thereby controlling the length of the upper lifting rope 28 between the two inverted T-shaped adjustment seats 27. The staff also uses the two inverted T-shaped adjustment seats 27 to synchronously move closer to the center of the square lifting beam 1, so that the upper lifting rope 28 is stored in the square lifting beam 1, and the square lifting beam 1 is raised, shortening the distance between it and the hook, and adjusting it to a suitable height.

[0063] Finally, the staff observes the distance between the square lifting beam 1 and the lifting component, and manually rotates the lower lifting handle 341 to rotate the lower lifting screw 34, thereby driving the two square adjustment seats 35 to synchronously approach the center of the square lifting beam 1. Then, the lower lifting wire rope pulley 1 352 is driven to retract the lower lifting rope 37 into the square lifting beam 1. After the lower lifting rope 37 is adjusted to the appropriate position, the lower lifting handle 341 is stopped from being rotated.

[0064] Then, the staff manually puts the lower lifting rope 37 onto the lifting position of the lifting component, and rotates the lower lifting handle 341 again to retract the lower lifting rope 37 into the square lifting beam 1, and tightens the lower lifting handle 37, and then the lifting component can be lifted.

[0065] When it is necessary to release the lifting piece, the staff lifts the lifting piece to the corresponding position, and then rotates the lower lifting handle 341 in the opposite direction to extend the lower lifting rope 37 from the square lifting beam 1, and then separates the lower lifting rope 37 from the lifting piece, so that the staff can separate the lower lifting rope 37 from the lifting piece, thereby completing the lifting work and moving the square lifting beam 1 to the storage position.
