Support belt 2 608, connecting block 609, connecting rod 610 and circular hole 611, one end of rope 1 602 is movably connected to the surface of connecting head 601, one end of rope 2 604 is movably connected to the surface of connecting head 601, the other end of rope 1 602 is fixedly installed on the end of support block 1 603, the other end of rope 2 604 is fixedly installed on the end of support block 2 605, one end of rope 3 606 is movably connected to the surface of connecting head 601, the surface of support belt 1 607 is fixedly connected to rope 3 606, and the surface of support belt 2 608 is fixedly connected to rope 3 606.

[0024] Specifically: when the device starts to be used, the crane works by coordinating the extension and shortening of the telescopic arm 4 with the extension and shortening of the steel cable 301. The hook body 5 set by the support component 6 is fixed with the support block 1 603 and the support block 2 605 on the support component 6 at both ends of the object to be lifted. The support belt 1 607 and the support belt 2 608 pass through the bottom of the object to form a package to support the object so that the object can be lifted. When the support point falls off, the object can continue to be lifted through other supports, and the object will not fall, making the device more perfect.

[0025] In one embodiment, a limiting block 401 is fixedly mounted on the surface of the telescopic arm 4 , and a steel cable 301 is movably mounted on the inner wall of the limiting block 401 .

[0026] Specifically, the steel cable 301 moves along the inner wall of the limiting block 401 fixedly mounted on the surface of the telescopic arm 4, so that the movement of the steel cable 301 is restricted by the limiting block 401, thereby preventing the steel cable 301 from deflecting and making the device more perfect.

[0027] In one embodiment, the surface of the connector 601 is movably mounted on the inner wall of the hook body 5 , the number of ropes 1 602 is two, and the number of ropes 2 604 is two.

[0028] Specifically: the connecting head 601 is installed on the inner wall of the hook body 5, so that the hook body 5 is hooked to the connecting head 601, and the two ropes 1 602 are respectively fixedly installed on the two ends of the support block 1 603, and the two ropes 2 604 are respectively fixedly installed on the two ends of the support block 2 605. By putting the rope 2 604 on one end of the object to be lifted, and the support block 2 605 on the other end of the object to be lifted, the two ends of the object are fixed when lifting, so that the object can be lifted better and the device is more perfect.

[0029] In one embodiment, the number of ropes 2 604 is four, and they are divided into two groups. The other end of one rope 3 606 is fixedly mounted on the surface of support belt 1 607, and the other end of another rope 3 606 is fixedly mounted on the surface of support belt 2 608. The connecting block 609 is fixedly mounted on one end of support belt 1 607, the connecting rod 610 is movably connected to the inner wall of the connecting block 609, the surface of support belt 2 608 is movably embedded in the inner wall of the connecting block 609, the circular hole 611 is opened on the surface of support belt 2 608, and the connecting rod 610 is movably embedded in the inner wall of the circular hole 611.

[0030] Specifically: pass the two support belts 607 through the bottom of the object to be lifted, pass the corresponding support belt 608 through the inner wall of the corresponding connecting block 609, and pass the movably connected connecting rod 610 on the connecting block 609 into the inner wall of the appropriate circular hole 611, so that the surface of the object is supported and fixed. In this way, when the support point falls off during the process of lifting the object, the object can continue to be lifted through other supports to prevent the object from falling, making the device more perfect.

[0031] In one embodiment, a fixing block 1 7 is fixedly installed on the surface of the hook body 5, and a fixing block 2 8 is fixedly installed on the surface of the hook body 5. The inner wall of the fixing block 1 7 is threadedly embedded with bolts 9, and the number of bolts 9 is two, and the surface threads of the bolts 9 are embedded inside the fixing block 2 8.

[0032] Specifically: After the limiting block 401 is hung on the inner wall of the hook body 5, the two bolts 9 are rotated so that the bottom surface of the bolts 9 is screwed into the inner wall of the fixing block 2 8, so that the hook body 5 forms a closed loop, so that the limiting block 401 installed on the inner wall of the hook body 5 will not fall off during the use of the device, so that the objects can be better lifted and the device is more perfect.

[0033] Working principle: When the device starts to be used, the crane works by coordinating the extension and contraction of the telescopic arm 4 with the extension and contraction of the steel cable 301. The steel cable 301 moves on the inner wall of the limiting block 401 fixedly installed on the surface of the telescopic arm 4, so that the movement of the steel cable 301 is restricted by the limiting block 401 to prevent the steel cable 301 from deflecting. The connecting head 601 is installed on the inner wall of the hook body 5, so that the hook body 5 is hooked to the connecting head 601. The two ropes 1 602 are respectively fixedly installed on the two ends of the support block 1 603, and the two ropes 2 604 are respectively fixedly installed on the two ends of the support block 2 605. By putting the support block 1 603 on one end of the object to be lifted and the support block 2 605 on the other end of the object to be lifted, the two ends of the object are supported when lifting. By passing the two support belts 1 607 through the bottom of the object to be lifted, the corresponding support belts The second 608 passes through the inner wall of the corresponding connecting block 609, so that the movably connected connecting rod 610 on the connecting block 609 passes through the inner wall of the appropriate circular hole 611, so that the surface of the object is supported and fixed, so that when the support point falls off during the process of lifting the object, the object can be continued to be lifted by other supports, so that the object will not fall off, making the device more perfect; when the device is in use, after the limiting block 401 is hung on the inner wall of the hook body 5, the two bolts 9 are rotated so that the surface of the bottom of the bolt 9 is screwed into the interior of the fixing block 2 8, so that the hook body 5 forms a closed loop, so that the limiting block 401 installed on the inner wall of the hook body 5 will not fall off during the use of the device, and the bolt 9 is rotated in the opposite direction so that the bottom of the bolt 9 is screwed out from the interior of the fixing block 2 8, so that the limiting block 401 can be removed, so that the object can be better lifted, making the device more perfect.
