[0027] Embodiment 1:

[0028] like Figure 1 , Figure 2 , Figure 4As shown, a safety anti-falling device for building construction comprises a supporting mechanism 1, on which a first protective mechanism 2 and a second protective mechanism 3 are arranged, wherein the second protective mechanism 3 is located above the first protective mechanism 2; the supporting mechanism 1 comprises four vertical poles 11; the first protective mechanism 2 comprises a first horizontal plate 21, a first extension plate 22, a second horizontal plate 23 and a second extension plate 24 respectively fixed to different vertical poles 11, one end of the first extension plate 22 slides in the first horizontal plate 21, one end of the second extension plate 24 slides in the second horizontal plate 23, the first horizontal plate 21 and the second horizontal plate 23 are located on two vertical poles 11 on the same side, the first extension plate 22 and the second extension plate 24 are located on two vertical poles 11 on the same side, and the second horizontal plate 23 is located below the first horizontal plate 21 and close to the vertical poles 11. The second cross plate 23 is staggered and arranged in an interlaced manner; a first limit block 25 is fixedly connected to the upper end surface of the second cross plate 23, a first limit groove 211 adapted to the first limit block 25 is provided on the lower end surface of the first cross plate 21, and the first limit block 25 is slidably connected in the first limit groove 211, a second limit block 26 is fixedly connected to the upper end surface of the second extension plate 24, a second limit groove 221 adapted to the second limit block 26 is provided on the lower end surface of the first extension plate 22, and the second limit block 26 is slidably connected in the second limit groove 221, the cross-sections of the first limit block 25 and the second limit block 26 may be T-shaped or dovetail-shaped, in the present embodiment they are T-shaped, the first limit block 25 and the second limit block 26 are parallel to each other and the length directions are perpendicular to the sliding directions of the first extension plate 22 and the second extension plate 24. By cooperating between the first limit block 25 and the first limit groove 211 and between the second limit block 26 and the second limit groove 221, the stability of the first protective mechanism 2 can be improved, and when the vertical pole 11 connected to the first extension plate 22 and the second extension plate 24 is moved, the first extension plate 22 and the second extension plate 24 can slide synchronously and adjust the covering area of ​​the first protective mechanism 2 along the sliding direction thereof, and when the vertical pole 11 connected to the second cross plate 23 and the second extension plate 24 is moved, the second cross plate 23 and the second extension plate 24 can slide synchronously and adjust the covering area of ​​the first protective mechanism 2 along the sliding direction thereof, thereby meeting the covering and protection requirements of machines of different sizes (such as mixers, steel bar cutting machines).

[0029] like Figure 1 , Figure 2 , Figure 5As shown, the second protection mechanism 3 includes a first connection member 31, a second connection member 32, a third connection member 33 and a fourth connection member 34 fixedly connected to different upright poles 11, the first connection member 31, the second connection member 32, the third connection member 33 and the fourth connection member 34 are all L-shaped components, one end of the first connection member 31 slides in the second connection member 32, one end of the third connection member 33 slides in the fourth connection member 34, a first protection net 35 is arranged between the first connection member 31 and the second connection member 32, and a third protection net 35 is arranged between the third connection member 33 and the fourth connection member 34. Two protective nets 36, the first protective net 35 is fixedly connected to the first connecting member 31 and the second connecting member 32, the second protective net 36 is fixedly connected to the third connecting member 33 and the fourth connecting member 34, the first protective net 35 and the second protective net 36 are nylon rope nets, which can intercept falling objects and alleviate the impact force of falling objects. When the distance between the first connecting member 31 and the second connecting member 32 is the farthest, the first protective net 35 is still in the middle drooping state, and when the distance between the third connecting member 33 and the fourth connecting member 34 is the farthest, the second protective net 36 is still in the middle drooping state.

[0030] like Figure 1 , Figure 2 , Figure 5 As shown, the second protective mechanism 3 also includes a third limit block 37 fixedly connected to the third connecting member 33 and the fourth connecting member 34. The first connecting member 31 and the second connecting member 32 are both provided with a third limit groove 38 adapted to the third limit block 37. The cross-section of the third limit block 37 can be T-shaped or dovetail-shaped, and is T-shaped in the present embodiment. The sliding direction of the third limit block 37 is perpendicular to the sliding direction of the first limit block 25 and the second limit block 26. The first protective net 35 and the second protective net 36 are staggered up and down. Before the third limit block 37 slides out of the third limit groove 38, in the present embodiment, the second protective net 36 is located below the first protective net 35, and the projection of the first protective net 35 is always staggered with the projection of the second protective net 36. Since the first protective mechanism 2 and the second protective mechanism 3 are both connected to the vertical pole 11, when the covering area of ​​the first protective mechanism 2 is adjusted, the covering protection area of ​​the second protective mechanism 3 can be adjusted synchronously, and the first protective net 35 and the second protective net 36 can intercept falling objects and alleviate the impact force of falling objects, reduce the impact force when falling objects hit the first protective mechanism 2, and improve the service life of the first protective mechanism 2.

[0031] like Figure 1 , Figure 2 , Figure 4As shown, the lower end face of the vertical pole 11 is fixedly connected with a mounting plate 12, and the lower end face of the mounting plate 12 is provided with a universal wheel 13, so that the safety anti-falling device is easy to move and more convenient to adjust the covering area of ​​the first protective mechanism 2 and the second protective mechanism 3. The mounting plate 12 is provided with a parking mechanism 4, which is used to prevent the universal wheel 13 from rotating after the covering area of ​​the device is adjusted. The parking mechanism 4 includes a threaded rod 41 that penetrates and is threadedly connected to the mounting plate 12, and the end of the threaded rod 41 located below the mounting plate 12 is fixedly connected with a stop block 42, which is a rubber block. By rotating the threaded rod 41, the stop block 42 is in contact with the surface of the wheel body of the universal wheel 13, and the universal wheel 13 cannot rotate due to friction, so that the distance between the vertical poles 11 remains unchanged, and thus the covering area of ​​the first protective mechanism 2 and the second protective mechanism 3 remains unchanged.

[0032] The working principle of a safety anti-falling device for building construction in the present embodiment is as follows: when in use, at least two workers are required to cooperate. First, the device is moved above the machine that needs to be protected from falling. When the vertical pole 11 connected to the first extension plate 22 and the second extension plate 24 is moved, the first extension plate 22 and the second extension plate 24 can slide synchronously and adjust the covering area of ​​the first protection mechanism 2 along the sliding direction. At the same time, the first connecting member 31 and the second connecting member 32 in the second protection mechanism 3 are separated from each other, and the third connecting member 33 and the fourth connecting member 34 are separated from each other, so that the lowest points of the first protection net 35 and the second protection net 36 move upward and increase the protection area; when the vertical pole 11 connected to the second cross plate 23 and the second extension plate 24 is moved, The second cross plate 23 and the second extension plate 24 can be made to slide synchronously, and the covering area of ​​the first protective mechanism 2 can be adjusted along the sliding direction. At the same time, the first connecting member 31 and the third connecting member 33 are moved away from each other, and the second connecting member 32 and the fourth connecting member 34 are moved away from each other, so that the interlaced area between the first protective net 35 and the second protective net 36 is reduced, thereby increasing the total protection area of ​​the first protective net 35 and the second protective net 36, and finally meeting the covering and protection requirements of machines of different sizes. After the adjustment is completed, each threaded rod 41 is rotated to make the abutment block 42 abut against the surface of the wheel body of the universal wheel 13, and the universal wheel 13 cannot be rotated through friction, so that the distance between the vertical rods 11 remains unchanged, thereby keeping the covering area of ​​the first protective mechanism 2 and the second protective mechanism 3 unchanged.

[0033] Embodiment 2:

[0034] like Figure 6 , Figure 7As shown, the difference from the first embodiment lies in that a plurality of first plug holes 251 are opened at equal intervals on the first limit block 25, a first plug rod 27 with one end located in the first limit groove 211 is inserted on the first cross plate 21, and the first plug rod 27 is adapted to the first plug hole 251; a plurality of second plug holes 261 are opened at equal intervals on the second limit block 26, a second plug rod 28 with one end located in the second limit groove 221 is inserted on the first extension plate 22, and the second plug rod 28 is adapted to the second plug hole 261; a plurality of third plug holes 371 are opened at equal intervals on the third limit block 37, a third plug rod 39 with one end located in the third limit groove 38 is inserted on both the first connecting member 31 and the second connecting member 32, and the third plug rod 39 is adapted to the third plug hole 371.

[0035] The working principle of a safety anti-falling device for building construction in this embodiment is: after adjusting the spacing between the vertical poles 11, the first plug rod 27 is inserted into the first cross plate 21 and the first plug hole 251 at a suitable position, the second plug rod 28 is inserted into the first extension plate 22 and the second plug hole 261 at a suitable position, and the two third plug rods 39 are respectively inserted into the corresponding first connecting member 31 or the second connecting member 32 and the third plug hole 371 at a suitable position. Because the sliding direction of the third limit block 37 is perpendicular to the sliding direction of the first limit block 25 and the second limit block 26, after the insertion of the plug rods, the change of the spacing between the vertical poles 11 can be further avoided, thereby avoiding the change of the adjusted covering protection area.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded 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 utility model shall be included in the protection scope of the utility model.
