[0002] Beam spreaders are suitable for the transportation of large goods. Currently, the most common beam spreaders are mainly composed of a main beam, and then the main beam is provided with lifting lugs with adjustable spacing.

[0011] The rotation of the longitudinal shaft can drive the first slider to move inside the longitudinal beam body. Since the first slider is fixed to the first lifting ear, and the first lifting ear is fixed to the middle part of the crossbeam body, the crossbeam body moves together with the slider. Since the two first sliders are respectively adapted to the two first thread segments with opposite directions, the two first sliders move in opposite directions, that is, the distance between the two crossbeam bodies can be adjusted by rotating the longitudinal shaft.

[0012] Preferably, the crossbeam assembly comprises a transverse axis and a second slider;

Since the second slider is fixed to the second lifting ear, the second lifting ear will move together with the second slider. Since the two second sliders are respectively adapted to the two second threaded sections with opposite directions, the two second blocks move in opposite directions, that is, the distance between the two second lifting ears can be adjusted by rotating the transverse axis.

[0017] Preferably, a rack parallel to the longitudinal axis is provided inside the longitudinal beam body;

[0025] Preferably, the linkage gears include three, so as to achieve sufficient variation coverage of the moving speed while keeping the structure not too complicated.

[0026] Preferably, a hand wheel is provided at the end of the longitudinal rotating shaft outside the longitudinal beam body, so as to facilitate manual control of the rotation of the longitudinal rotating shaft.

[0027] Preferably, the first sliding block is provided with a first linkage pin, and the end of the first linkage pin is passed through the longitudinally moving strip hole to the outside and connected to the first lifting ear, so as to facilitate the connection.

[0042] The rotation of the longitudinal shaft 5 can drive the first slider 7 to move inside the longitudinal beam body 1. Since the first slider 7 is fixed to the first lifting ear 8, and the first lifting ear 8 is fixed to the middle of the crossbeam body 9, the crossbeam body 9 moves together with the slider. Since the two first sliders 7 are respectively adapted to the two first threaded sections 6 with opposite directions, the two first sliders 7 move in opposite directions, that is, the distance between the two crossbeam bodies 9 can be adjusted by rotating the longitudinal shaft 5.

[0043] The crossbeam assembly includes a lateral rotation axis 11 and a second sliding block 13;

[0044] The transverse rotation shaft 11 is rotatably matched inside the crossbeam body 9, and the two ends of the transverse rotation shaft 11 are respectively provided with second thread segments 12 with opposite directions, and the second thread segments 12 are respectively threadedly adapted with second sliders 13;

[0045] The side wall of the cross beam body 9 is provided with a transverse strip hole 10 parallel to the transverse rotation axis 11;

[0046] The exterior of the cross beam body 9 is slidably fitted with a second lifting ear 14 , and the second lifting ear 14 is connected to the second sliding block 13 through the transverse strip hole 10 .

[0047] The rotation of the transverse axis 11 can drive the second slider 13 to move inside the beam body 9.

Since the two second sliders 13 are respectively adapted to the two second threaded sections 12 with opposite directions, the two second blocks move in opposite directions, that is, the distance between the two second lifting ears 14 can be adjusted by rotating the transverse axis 11.

It can quickly realize the switching between large and small volume cargoes, and significantly improve the efficiency of the use of the spreader.

[0055] The driving gear 16 includes a plurality of coaxially fixed linkage gears, each of which has a different outer diameter, and the rack 4 includes a plurality of rack 4 sections corresponding to each of the linkage gears, and each of the rack 4 sections is terminated and connected in sequence. When linkage gears with different outer diameters are used, the rotation speed will change when they cooperate with the rack 4, so as to change the speed according to different length intervals to achieve rapid switching adaptation of the cargo, thereby improving the efficiency of the sling in hoisting the cargo.
