[0035] In order to solve the problems existing in the prior art, an embodiment of the present application provides a lifting device, such as Figure 1-4 As shown, it comprises: a hanging plate 1; two groups of hanging arms respectively connected to the two opposite side edges of the hanging plate, each group of hanging arms comprises two hanging walls 2, the hanging walls 2 are rotatably connected to the hanging plate, and can reciprocate along the extension direction of the side of the hanging plate, that is, the hanging walls 2 can reciprocate along the extension direction of the corresponding side of the hanging plate; the end of the hanging wall 2 away from the hanging plate is rotatably connected to two hooks 3, and the two hooks 3 are arranged in mirror symmetry through a connecting shaft 33. Preferably, one end of the hanging wall 2 connected to the hook 3 is U-shaped, that is, it has a first side wall 21 and a second side wall 22, and the two hooks 3 are connected between the first side wall 21 and the second side wall 22 through a connecting shaft 33.

[0036] In the above-mentioned embodiment of the present application, since the two hanging walls 2 in each group of hanging arms reciprocate in the extending direction of the side edge of the hanging plate 1, the relative positions of the four hanging walls 2 and the hooks 3 on the corresponding hanging walls 2 can be adjusted according to the positions of the hanging ropes on the suspended goods; for example, when the suspended goods have two symmetrically arranged hanging ropes, the two groups of hanging arms are respectively moved to symmetrical positions, and the two hanging walls 2 in each group of hanging arms can be approached to each other and close together, and the corresponding hanging ropes are hung on the hooks 3 connected to the two hanging walls 2, so that the hooks 3 on the two hanging walls 2 can hook the corresponding hanging ropes on the suspended goods, thereby reducing the weight borne by a single hanging wall 2; when the hanging ropes on the suspended goods have four evenly arranged hanging ropes, When the two hanging walls 2 in each group of hanging arms are moved to the two ends of the corresponding side of the hanging plate, each hanging wall 2 is rotated to a suitable position, and the hanging rope is hung on the hook 3 connected to the corresponding hanging wall 2, so that the four hanging walls 2 can be evenly stressed, and the goods to be hung can be lifted and moved to the unloading platform by the hoisting machine; in addition, the mirror-symmetrical arrangement of the two hooks 3 on each hanging wall 2 can make the two hooks 3 relative to each other and form a wrapping area when the two hooks 3 are hooked on the hanging rope, and the hanging rope is located in the wrapping area and will not be separated from the hook 3, which has stronger stability, and if one of the hooks 3 is damaged, the other hook 3 can also hook the hanging rope, which will not affect the use of the entire lifting device. The lifting device provided by the present application can adjust the position of the hanging wall 2 and the hook 3 according to the position of the hanging rope on the goods, and can also choose to use the corresponding hanging wall 2 and hook 3 according to the number of hanging ropes. The arrangement of the two hooks 3 on each hanging wall 2 makes the hanging rope located in the wrapping area and will not be separated from the hook 3, which has stronger stability.

[0037] In a specific embodiment, the hanging plate 1 includes an upper hanging plate 11, and a lower hanging plate 12 arranged opposite to the upper hanging plate 11; the hanging wall 2 is rotatably connected between the upper hanging plate 11 and the lower hanging plate 12 through the connecting fixture 4, and the hanging wall 2 can move between the upper hanging plate 11 and the lower hanging plate 12. The arrangement of the upper hanging plate 11 and the lower hanging plate 12 can protect the end of the hanging wall 2 connected to the hanging plate from being damaged, and when the connection between the hanging wall 2 and the hanging plate becomes loose, the upper hanging plate 11 and the lower hanging plate 12 can also play a blocking role, especially during the transportation of the suspended goods, the upper hanging plate 11 can prevent the hanging wall 2 from detaching from the entire hanging device.

[0038] In a specific example, the two opposite side edges of the upper hanging plate 11 include a first slide groove 13, and the extension direction of the first slide groove 13 is the same as the extension direction of the side of the corresponding upper hanging plate 11; the cross-section of the upper hanging plate 11 here can be rectangular, preferably square, and the two opposite sides refer to one of the two opposite sides of the four sides of the upper hanging plate 11 that are opposite to each other; the two opposite side edges of the lower hanging plate 12 include a second slide groove (not shown in the figure) corresponding to the first slide groove 13, and the extension direction of the second slide groove is the same as the extension direction of the side of the corresponding lower hanging plate 12; here, the upper hanging plate 11 and the lower hanging plate 12 are symmetrically arranged, and the cross-section of the lower hanging plate 12 is the same as that of the upper hanging plate 11 and can also be rectangular, preferably square, and the two opposite sides refer to one of the two opposite sides of the four sides of the upper hanging plate 11 that are opposite to each other; the end of the hanging wall 2 away from the hook 3 can move along the first slide groove 13 and the second slide groove corresponding to the first slide groove 13. The first slide groove 13 and the second slide groove enable the hanging wall 2 to move back and forth along the sides of the upper hanging plate 11 and the lower hanging plate 12, that is, to change the position of the hanging wall 2. Specifically, the first slide groove 13 penetrates from the top surface of the upper hanging plate 11 to the bottom surface of the upper hanging plate 11; the second slide groove penetrates from the top surface of the lower hanging plate 12 to the bottom surface of the lower hanging plate 12.

[0039] In a specific embodiment, the end of the hanging wall 2 away from the hook 3 includes a connection hole (not shown in the figure) extending from the top surface of the hanging wall 2 to the bottom surface of the hanging wall 2; the connecting fixture 4 passes through the first slide groove 13, the connecting hole and the second slide groove from the top surface of the upper hanging plate 11 to the bottom surface of the lower hanging plate 12 in sequence to connect the hanging wall 2 to the first hanging plate and the second hanging plate. The setting of the connecting hole and the connecting fixture 4 not only realizes the connection between the hanging wall 2 and the upper hanging plate 11 and the lower hanging plate 12, but also realizes the rotation of the hanging wall 2, that is, the relative rotation between the hanging wall 2 and the hanging plate.

[0040] Specifically, the connecting fixing member 4 includes a connecting member 41 that passes through the first slide groove 13, the connecting hole and the second slide groove in sequence to the bottom surface of the lower hanging plate 12, so that the hanging wall 2 can be rotated with the connecting member 41 as the axis to change the posture of the hanging wall 2; here, a thread is provided on the outer wall of the connecting member 41; the connecting fixing member 4 also includes two first fixing members 42 respectively located above the upper hanging plate 11 and below the lower hanging plate 12, and the first fixing members 42 are screwed to the connecting member 41; two second fixing members 43 respectively located between the hanging wall 2 and the upper hanging plate 11 and between the hanging wall 2 and the lower hanging plate 12, and the second fixing members 43 are screwed to the connecting member 41. When the wall hanging 2 moves to the preset position and adjusts its posture, the two second fixing members 43 are rotated until the two second fixing members 43 are respectively abutted and fixed with the top surface and the bottom surface of the wall hanging 2, so that the connecting member 41 and the two second fixing members 43 form a whole and will not rotate relative to each other; then the two first fixing members 42 are rotated until the two first fixing members 42 are respectively abutted and fixed with the top surface of the upper hanging plate 11 and the bottom surface of the lower hanging plate 12, so that the connecting member 41 can be fixed in the first sliding groove 13 and the second sliding groove, and will not move in the first sliding groove 13 and the second sliding groove, that is, the wall hanging 2, the connecting member 41, the upper hanging plate 11 and the lower hanging plate 12 form a whole and will not move relative to each other. That is to say, at this time, the wall hanging 2 will no longer move and rotate relative to the upper hanging plate 11 and the lower hanging plate 12, and can always maintain its position and posture relative to the upper hanging plate 11 and the lower hanging plate 12. When the hanging wall 2 needs to be moved, the two first fixing members 42 are loosened, and the connecting member 41 can move in the first sliding groove 13 and the second sliding groove. When the hanging wall 2 needs to be rotated at the same time, the two second fixing members 43 are loosened, and the hanging wall 13 can rotate relative to the connecting member 43.

[0041] Specifically, the outer diameter of the first fixing member 42 is larger than the width of the first slide groove 13 and the second slide groove; the outer diameter of the second fixing member 43 is larger than the aperture of the connecting hole. In this way, the first fixing member 42 can fix the connecting member 41 on the hanging plate, and the second fixing member 43 can fix the hanging wall 2 on the connecting member 41.

[0042] In a specific embodiment, the hook 3 includes a hook body 31 and a hook handle 32 connected to the hook body 31, the weight of the hook handle 32 is greater than the weight of the hook body 31; the connection between the hook body 31 and the hook handle 32 is connected to the hanging wall 2 through the connecting shaft 33. When the hoisting machine places the suspended cargo on the unloading platform, the suspended cargo no longer exerts gravity on the hook body 31, and the hook body 31 can rotate around the connecting shaft 33 under its own gravity. When the hook body 31 is rotated to the opening facing downward, the hook body 31 and the hanging rope on the suspended cargo can be automatically separated, that is, the suspended cargo can be automatically unhooked.

[0043] In a specific embodiment, a vertically placed connecting plate 5 is connected and fixed to the top of the upper hoisting plate 11, and the connecting plate 5 includes a through hole 51. The arrangement of the connecting plate 5 and the through hole 51 on the connecting plate 5 allows the hook 3 on the hoisting machine to directly pass through the through hole 51 to hoist the entire hoisting device, that is, the hoisted goods hung on the hoisting device can be hoisted.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
