[0025] A rope is provided on the fixed pulley 8 for connecting the steel structure components and lifting the steel structure components. The fixed pulley 8 is connected to the bracket 7 through a hook, which facilitates the use of the fixed pulley 8.

[0026] Specifically, Figure 1 and Figure 3 As shown, a label 9 is bonded to the outer surface of the plug board 2, and the label 9 is used to facilitate understanding of relevant parameter information of the device.

[0027] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the materials of the insert plate 2, the support plate 3 and the bracket 7 are all made of stainless steel, which has the characteristics of high strength and corrosion resistance.

[0028] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the bracket 7 and the support plate 3 are fixed by arc welding, and have high strength and durability.

[0029] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stabilizing mechanism 4 includes a threaded rod 41 rotatably connected to the inner surface of the plug plate 2, the upper end of the threaded rod 41 is fixedly connected to a rotating block 42, the outer surface of the threaded rod 41 is threadedly connected to a connecting plate 43, and the lower surface of the connecting plate 43 is symmetrically fixedly connected to two stabilizing rods 44, both of which are slidably connected to the plug plate 2, and the stabilizing rods 44 are slidably plugged into the socket 5.

[0030] When in use, two insertion holes 5 are opened on the steel frame beam 1, and then the plug plate 2 is plugged into the steel frame beam 1, and then the rotating block 42 is rotated, and the threaded rod 41 is driven to rotate by the rotation of the rotating block 42, and then the connecting plate 43 is driven to move down by the rotation of the threaded rod 41, and then the stabilizing rod 44 is driven to move down and plug into the insertion hole 5, so as to stabilize the plug plate 2, so that the plugging of the plug plate 2 and the steel frame beam 1 is stably connected, and then one end of the rope on the fixed pulley 8 is connected to the steel structure component, and it is slowly lifted manually through the fixed pulleys 8 on the two sets of devices, and then the steel structure component is removed by the workers on the steel frame beam 1;

[0031] The function of quick disassembly and assembly of the plug plate 2 is realized. Through the cooperation of the threaded rod 41, the rotating block 42, the connecting plate 43 and the stabilizing rod 44, the plug plate 2 can be quickly disassembled and assembled. Then, through the cooperation of the plug plate 2, the support plate 3, the bracket 7 and the fixed pulley 8, the possibility of collision between the installed components due to the narrow lifting space of the crane is effectively avoided, thereby reducing the frequent displacement of the crane, saving labor and time, and accelerating the construction efficiency.

[0032] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the adjustment mechanism 6 includes a threaded rod 61 threadedly connected to the inner surface of the support plate 3, the threaded rod 61 is rotatably connected to the plug plate 2, one end of the threaded rod 61 is fixedly connected to a rotating block 62, and the inner surface of the support plate 3 located outside the threaded rod 61 is symmetrically slidably connected to two limit rods 63, and the two limit rods 63 are fixedly connected to the plug plate 2.

[0033] When in use, when there is a deviation in the installation positions of the two plug boards 2, the second rotating block 62 is rotated, and the second threaded rod 61 is rotated by the rotation of the second rotating block 62, and then the support plate 3 is moved by the rotation of the second threaded rod 61, and then the bracket 7 is moved, and then the fixed pulley 8 is moved to a suitable position by the movement of the bracket 7, so that the two support plates 3, the two brackets 7 and the two fixed pulleys 8 are in the same vertical plane. In this process, the movement of the support plate 3 is stable through the limit rod 63;

[0034] The function of adjusting the position of the support plate 3, the bracket 7 and the fixed pulley 8 is realized. Through the cooperation of the threaded rod 2 61, the rotating block 2 62 and the limit rod 63, the position of the support plate 3, the bracket 7 and the fixed pulley 8 can be adjusted.

[0036] Specifically, Figure 3 and Figure 4 As shown, the outer surfaces of the rotating block 1 42 and the rotating block 2 62 are both provided with anti-slip grooves to increase the contact friction with the fingers, thereby facilitating the rotation of the rotating block 1 42 and the rotating block 2 62 .

[0037] Working principle: when in use, two plug holes 5 are opened on the steel frame beam 1, and then the plug plate 2 is plugged into the steel frame beam 1, and then the rotating block 42 is rotated, and the threaded rod 41 is driven to rotate by the rotating block 42, and then the connecting plate 43 is driven to move down by the rotation of the threaded rod 41, and then the stabilizing rod 44 is driven to move down and plug into the plug hole 5, so that the plug plate 2 and the steel frame beam 1 are plugged stably, and then one end of the rope on the fixed pulley 8 is connected to the steel structure component, and it is slowly lifted manually through the fixed pulleys 8 on the two sets of devices, and then hoisted to the construction work surface, and then the workers on the steel frame beam 1 remove the steel structure component;

[0038] During the above operation, if it is found that there is a deviation in the installation position of the two plug plates 2, which affects the lifting of the steel structure components, the rotating block 62 can be rotated, and the threaded rod 61 can be rotated by rotating the rotating block 62, and then the support plate 3 is driven to move by rotating the threaded rod 61, and then the bracket 7 is driven to move, and then the fixed pulley 8 is driven to move to the appropriate position by the movement of the bracket 7, so that the two support plates 3, the two brackets 7 and the two fixed pulleys 8 are in the same vertical plane.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
