[0042] As the present embodiment, the lifting frame 14 is designed to have an open-and-close structure. The load-bearing frame plate 23 is used to load goods, the supporting bracket 22 is used to support the load-bearing frame plate 23, and the transmission inner frame 24 is used to control the opening and closing of the supporting bracket 22 and the load-bearing frame plate 23.

On the one hand, it can reduce the space occupied, and on the other hand, it can appropriately shrink the space, so that the goods can be fixed more tightly when the number of goods is small.

[0043] A rope positioning assembly 25 is provided on the periphery of the lifting frame 14. The rope positioning assembly 25 is used to tighten the cargo and fix it again along the peripheral area of ​​the inner space of the lifting frame 14, so as to further improve the stability of cargo lifting.

[0044] In one embodiment;

[0045] For the lifting frame 14, this embodiment designs the following specific implementation structure:

[0046] See also Figure 2 and Figure 3 Fixed end blocks 31 are installed at both ends of the hanging frame plate 21, and a supporting bracket 22 is installed on the fixed end block 31 through a driving shaft 32. The supporting bracket 22 includes a side wing frame plate 33 installed on the driving shaft 32, and an outer edge end 34 installed at the bottom end of the side wing frame plate 33. The outer edge end 34 is installed with an outer edge frame 35 through a movable shaft, and the outer edge frame 35 is respectively connected to the edge of the bearing frame plate 23 through a branch bracket rod 36.

[0047] The main body of the transmission inner frame 24 is free of a hydraulic drive rod 37, one end of which is provided with a fixed block 38 via a movable shaft, and the fixed block 38 is fixed to the side wing frame plate 33; the other end of the hydraulic drive rod 37 is connected to the outer edge frame 35 via a telescopic rod.

[0048] The lifting frame plate 21 is the top of the lifting frame 14, and the side wing frame plate 33 is the side wing component of the lifting frame 14. The flipping of the lifting frame 14 can be controlled by driving the rotating shaft 32. The outer edge end 34 is then installed with an outer edge frame 35 through a movable shaft. The outer edge frame 35 is further branched into a plurality of branch support rods 36 for fixing the load-bearing frame plate 23.

[0049] When the present embodiment is in operation, the side wing frame plates 33 are first driven to rotate by the driving shaft 32, and then the outer edge frame 35 is pushed to unfold with the outer edge end 34 as the support point by the hydraulic driving rod 37 as the driving end, so that the load-bearing frame plates 23 on both sides are assembled and closed with each other, and the load-bearing frame plates 23 form a load-bearing bottom plate for the goods, and the sub-supporting rods 36 on both sides, the outer edge frame 35, the side wing frame plates 33 and the hydraulic driving rod 37 form an outer frame, and are used to support and fix the load-bearing frame plates 23.

[0050] When folding, the movable end is driven inward by the hydraulic driving rod 37, thereby driving the outer edge frame 35 to fold toward the inner plate surface of the side wing frame plate 33, so that the load-bearing frame plates 23 are separated from each other, and the load-bearing frame plates 23 are converted from horizontal to vertical, and then the driving shaft 32 drives the side wing frame plates 33 to be brought inward, thereby shrinking and folding the side wing frame plates 33, thereby reducing the occupied area of ​​the entire lifting frame plate 21.

[0051] In one embodiment;

[0052] See also Figure 2 and Figure 4 In order to further ensure that the goods are loaded on the load-bearing frame plate 23, a loading net bag 49 is provided on the plate surface of the load-bearing frame plate 23, and the loading net bag 49 is respectively connected to a plurality of first tensioning ropes 48 and a plurality of second tensioning ropes 47; the loading net bag 49 is used to hold the goods.

[0053] See also Figure 3 and Figure 4 The side edges of the plate surface of the carrier plate 23 are respectively provided with a first rotating wheel 43 and a second rotating wheel 44; a first tensioning wheel 42 is also provided at the fixed end block 31, and the first tensioning wheel 42 is installed on the driving shaft 32 through a shaft sleeve 41, and does not move with the driving shaft 32; an inner support rod 45 is also installed at the side wing frame plate 33, and a second tensioning wheel 46 is installed on the inner support rod 45; a rope collecting assembly 51 is provided on the lifting frame plate 21, and the first tensioning rope 48 passes through the first rotating wheel 43, then changes direction through the first tensioning wheel 42, and is finally connected to the rope collecting assembly 51; the second tensioning rope 47 passes through the second rotating wheel 44, then changes direction through the second tensioning wheel 46, and is finally connected to the rope collecting assembly 51.

[0054] As an example, the attached drawings of this embodiment show a mechanism arrangement of the rope positioning assembly 25, and a first rotating wheel 43 and two second rotating wheels 44 are provided on the edge of each supporting frame plate 23, which are arranged equidistantly, and the first tensioning wheel 42 and the second tensioning wheel 46 are used for rotating and redirecting the first tensioning rope 48 and the second tensioning rope 47 respectively; a total of six first tensioning ropes 48 and the second tensioning ropes 47 are subsequently stored and tightened in the rope collection assembly 51.

[0055] Of course, the specific number of tension ropes, revolving wheels and tensioning wheels can be set according to actual needs.

[0056] In one case of this embodiment,

[0057] For the rope collecting assembly 51, the present embodiment designs the following operation implementation structure;

[0058] See also Figure 5The rope collecting assembly 51 includes a supporting frame 56 installed on the lifting frame plate 21, a rope collecting drum 52 rotatably installed on the supporting frame block 56, and a driving frame 54 arranged on the periphery of the rope collecting drum 52; a plurality of wire collecting pipe openings 53 are arranged on the disk surface of the rope collecting drum 52, the first tensioning rope 48 and the second tensioning rope 47 are both passed through the wire collecting pipe openings 53 and wound around the rope collecting drum 52, and a storage motor 55 is installed on the driving frame 54, and the storage motor 55 is used to drive the rope collecting drum 52 to rotate.

[0059] A driving frame 54 is provided on the hoisting frame 21, and a receiving motor 55 is used as a power source to drive the rope collection disc 52 to move, thereby driving the first tension rope 48 and the second tension rope 47 to be wound around the rope collection disc 52, and then used to tighten the first tension rope 48 and the second tension rope 47. A plurality of wire collection openings 53 are provided on the surface of the rope collection disc 52, and each tension rope is independently inserted into the wire collection opening 53, so as to avoid the phenomenon of the tension ropes being entangled with each other, so that each tension rope has a certain space interval, and can be sent and received freely.

[0060] In one case of this embodiment,

[0061] See also Figure 4 The outer edge of the carrier plate 23 is provided with a limited outer edge 71, and the inner edge thereof is provided with a combined inner strip 72. The combined inner strips 72 of the carrier plates 23 on both sides are made of magnetic materials that are attracted to each other. As for the combination of the carrier plates 23, the combined inner strips 72 of the embodiment are designed to be strip-shaped magnetic materials. When the carrier plates 23 on both sides are butted against each other, the combined inner strips 72 that are attracted to each other can realize the rapid connection of the carrier plates 23, thereby avoiding the existence of gaps between the carrier plates 23.

[0062] In one embodiment;

[0063] In view of the lifting process of the lifting frame 14, it is sometimes necessary to unload part of the cargo midway; and the winch used to control the sending and receiving of the lifting rope 17 often does not move at a uniform speed throughout the whole process; such situations will cause fluctuations in the load-bearing frame plate 23.

[0064] See also Figure 4 and Figure 6A pull bolt assembly 73 connected to the sub-bracket rod 36 is provided on the plate surface of the carrier plate 23; the pull bolt assembly 73 includes an oblique support fixing block 61 installed on the plate surface of the carrier plate 23, a connecting outer bolt 62 installed on the oblique support fixing block 61, and a connecting bolt 65 installed on the connecting outer bolt 62 and connected to the rod end of the sub-bracket rod 36. A buffer outer frame 63 is provided on the periphery of the connecting outer bolt 62. The connecting bolt 65 is installed in the buffer outer frame 63 in an insert type through an inner insert block 64 and then connected to the connecting outer bolt 62. The buffer outer frame 63 is an arc-shaped elastic structure and is supported between the connecting outer bolt 62 and the connecting bolt 65.

[0065] In this embodiment, the load-bearing frame plate 23 and the connecting bolt 65 are installed in a foldable combination, and the buffer outer frame 63 is wrapped around the periphery of the inner insert block 64 in an outwardly expanding manner. The buffer outer frame 63 has an arc-shaped elastic structure, thereby forming an elastic buffering effect; it effectively reduces the sub-support rod 36 from fluctuating with the lifting frame plate 21, driving the lifting frame plate 21 to fluctuate together, and at the same time avoids the collision of its connecting end, thereby playing the effect of properly buffering the fluctuation during the lifting process, and further improving the stability of the cargo lifting turnover.

[0066] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
