[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0021] like Figure 1 As shown;

[0022] A prefabricated building wall panel hoisting device comprises an earring 1 for passing a steel cable through and hanging on a tower crane hook, and a top plate 6 fixedly connected to the earring 1.

[0023] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "at present, the lifting equipment for prefabricated building wall panels mostly uses crane equipment to hook and lift the prefabricated building cavity panels. Before lifting, the prefabricated building wall panels need to be pre-bound in advance for lifting. This binding process mostly uses rope connections, which is cumbersome and easy to cause the prefabricated building wall panels to be detached, and the safety performance is insufficient." Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a centering displacement component 3, a centering displacement component 3, a left clamping and fixing component 4 and a right clamping and fixing component 5 are added on this basis.

[0024] like Figure 1-4 As shown in the figure;

[0025] In combination with the above content, in order to facilitate the stable fixation of the building wall panels and improve safety, it also includes a middle clamping and fixing component 2 arranged at the center of the bottom of the top plate 6 and a centering displacement component 3 arranged at the bottom of the top plate 6, as well as a left clamping and fixing component 4 and a right clamping and fixing component 5 arranged on the centering displacement component 3.

[0026] In an optional embodiment, the middle clamping and fixing component 2, the left clamping and fixing component 4 and the right clamping and fixing component 5 are all of the same size and structure.

[0027] In an optional embodiment, the centering displacement assembly 3 includes a baffle 31 fixed at both ends of the top plate 6, a rotating rod 32 is movably arranged between the two baffles 31 through a bearing, a reduction motor 33 is fixed to the side wall of the baffle 31, and the rotor of the reduction motor 33 is fixedly connected to the rotating rod 32. Threads in different directions are arranged at both ends of the rotating rod 32, and there is no thread structure in the middle part. The threads in different directions at both ends of the rotating rod 32 are respectively screwed with a left slide seat 34 and a right slide seat 35, and the rotation of the rotating rod 32 drives the left slide seat 34 and the right slide seat 35 to move in opposite directions.

[0028] In this embodiment: the reduction motor 33 drives the rotating rod 32 to rotate. Since threads in different directions are provided at both ends of the rotating rod 32, and the left slide 34 and the right slide 35 are respectively screwed on the threads in different directions at both ends of the rotating rod 32, the rotation of the rotating rod 32 drives the left slide 34 and the right slide 35 to move in opposite directions.

[0029] In an optional embodiment, the left clamping and fixing assembly 4 includes a bearing seat 41 fixed on the left sliding seat 34, and a left support arm 42 and a right support arm 43 are movably arranged on the bearing seat 41, and a left lower support arm 44 and a right lower support arm 45 are movably arranged on the left support arm 42 and the right support arm 43, respectively, and the left lower support arm 44 and the right lower support arm 45 are movably connected, a right pressure arm 46 and a left pressure arm 47 are movably arranged on the left lower support arm 44 and the right lower support arm 45, respectively, and the right pressure arm 46 and the left pressure arm 47 are movably connected, and a right support frame 48 and a left support frame 49 are respectively arranged at the bottom of the left lower support arm 44 and the right lower support arm 45.

[0030] In this embodiment: when heavy objects are placed on the right support frame 48 and the left support frame 49, the left slide 34 is lifted, and the angle between the left support arm 42 and the right support arm 43 becomes smaller, thereby driving the inner angle between the left lower support arm 44 and the right lower support arm 45 to become smaller. Since the right pressure arm 46 and the left pressure arm 47 are respectively arranged on the left lower support arm 44 and the right lower support arm 45, the angle between the right pressure arm 46 and the left pressure arm 47 becomes smaller at this time, and then the heavy objects on the right support frame 48 and the left support frame 49 are limited and tightened by the lower ends of the right pressure arm 46 and the left pressure arm 47.

[0031] Working principle of this utility model:

[0032] Place the wall panel on the right support frame 48 and the left support frame 49, and lift the left slide 34. Due to the gravity of the wall panel, the angle between the left support arm 42 and the right support arm 43 becomes smaller, thereby driving the inner angle between the lower left support arm 44 and the lower right support arm 45 to become smaller. Since the right pressure arm 46 and the left pressure arm 47 are respectively arranged on the lower left support arm 44 and the lower right support arm 45, the angle between the right pressure arm 46 and the left pressure arm 47 becomes smaller at this time, and then the weights on the right support frame 48 and the left support frame 49 are limited and tightened by the lower ends of the right pressure arm 46 and the left pressure arm 47. No manual operation is required, and clamping and fixing are automatically achieved. The three-point clamping and fixing of the middle clamping and fixing component 2, the left clamping and fixing component 4 and the right clamping and fixing component 5 can effectively avoid slipping and loose fixation during hoisting, thereby improving safety.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
