Technical Field
[0001] The utility model relates to the field of building construction, in particular to a supporting and protecting structure for a cantilever structure. Background Art
[0002] Cantilever structure is one of the common structural forms in engineering structures, such as awnings, eaves, and external balconies in construction projects. This structure is a cantilever structure formed by cantilevering beams or plate components from the main structure. Taking the I-beam cantilever as an example, the overall structure of the cantilever extends outward, especially the cantilever with a longer length. In fact, the stability is not good. If the cantilever is used to hang heavy objects, there is a risk of being bent and broken, and even causing the entire cantilever to break and fall. Therefore, in order to improve the stability and force strength of the cantilever, a supporting and protective structure is needed to provide protective support for it. Utility Model Content
[0003] In order to support and protect the cantilever, improve the stability of the cantilever and prevent the cantilever from bending easily when hanging heavy objects, the utility model provides a supporting and protecting structure for the cantilever structure, which is particularly suitable for the supporting and protecting structure for the I-beam cantilever structure.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a supporting and protective structure for a cantilever structure, comprising a connecting block and a fixed plate, wherein two plug rods are fixedly connected to the connecting block, two first brackets are fixedly connected to the top of the connecting block, a fixing rod is commonly fixedly connected between the two first brackets, one end of a suspension rope is fixedly connected to the fixing rod, a support plate is fixedly connected to the fixed plate, a sliding sleeve is slidably connected to the support plate, an outer shell and a second bracket are respectively fixedly connected on both sides of the lower end surface of the sliding sleeve, a rotating shaft is commonly rotatably connected between the outer shell and the second bracket, and the other end of the suspension rope is fixedly connected to the rotating shaft.
[0005] Preferably, a plurality of bolts are fixedly connected to the fixing plate, and a connecting plate is fixedly connected to one end of the support plate away from the fixing plate.
[0006] Preferably, a screw is connected to the fixing plate and the connecting plate for joint rotation, and the screw is threadedly connected to the sliding sleeve; one end of the screw passes through the connecting plate.
[0007] Preferably, the shell is a hollow structure, the rotating shaft passes through the shell, and one end of the rotating shaft is rotatably connected to the inner wall of the shell.
[0008] Preferably, one end of the rotating shaft located inside the housing is fixedly connected to a worm gear, and the suspension rope is wound around the rotating shaft.
[0009] Preferably, a rotating rod is rotatably connected to the side wall of the shell, a worm is fixedly connected to the rotating rod located inside the shell, the worm is meshed with the worm wheel, and one end of the rotating rod passes through the shell to form a handle.
[0010] Preferably, the two insertion rods are respectively fixedly connected to the two side edges of the connecting block, and the two insertion rods are symmetrically arranged on the connecting block.
[0011] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the structure can be used for supporting and protecting cantilever structures, especially I-beam cantilever structures, thereby improving the overall stability and force strength of the cantilever structure; specifically, by providing a connecting block and a suspension rope, the connecting block can be moved to the outward end of the I-beam cantilever, so that the two plug rods are inserted into the two sides of the I-beam cantilever, so that the two plug rods together with the connecting block are clamped on the I-beam cantilever, and then the fixing plate is fixed to the wall by bolts. At this time, the connecting block and the plug rod are pulled by the suspension rope above the connecting block. When a heavy object is hung on the cantilever, the gravity will be dispersed to the sliding sleeve through the suspension rope, thereby improving the load-bearing capacity of the cantilever. By setting the sliding sleeve and the shell, it is convenient to support and protect cantilevers of different lengths. The screw rod can be rotated, and the rotation of the screw rod can make the sliding sleeve slide on the support plate, so that the end of the lifting rope located on the connecting block is fixed, and the end of the lifting rope located below the sliding sleeve can move with the movement of the sliding sleeve, so that the lifting rope is in a vertical downward direction as much as possible. The height difference between the fixed plate and the connecting block in the vertical direction will change the required length of the lifting rope. According to the height difference between the two, the length of the lifting rope can be adjusted. The specific operation is to rotate the rotating rod on the shell. The rotation of the rotating rod drives the worm in the shell to rotate, and the worm drives the worm wheel meshing with it to rotate. The rotation of the worm wheel drives the rotating shaft to rotate, thereby changing the number of turns of the lifting rope wrapped around the rotating shaft, thereby changing the length of the lifting rope between the sliding sleeve and the connecting block to adapt to different height differences between the connecting blocks and the sliding sleeve.

DETAILED DESCRIPTION
[0017] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation modes of the present invention will be further described in detail below with reference to the accompanying drawings.
[0018] See also Figures 1 to 3 The embodiment of the present invention provides a support and protection structure for a cantilever structure, including a connection block 1 and a fixing plate 6, two plug rods 2 are fixedly connected to the connection block 1, two first brackets 3 are fixedly connected to the top of the connection block 1, a fixing rod 4 is fixedly connected between the two first brackets 3, one end of a suspension rope 5 is fixedly connected to the fixing rod 4, a support plate 8 is fixedly connected to the fixing plate 6, a sliding sleeve 11 is slidably connected to the support plate 8, a shell 13 and a second bracket 12 are fixedly connected to both sides of the lower end surface of the sliding sleeve 11, a rotating shaft 14 is rotatably connected between the shell 13 and the second bracket 12, and the other end of the suspension rope 5 is fixedly connected to the rotating shaft 14. The connection block 1 and the plug rod 2 are fixedly connected to the I-beam cantilever, and then the fixing plate 6 is fixed to the wall, so that the cantilever can be pulled by the suspension rope 5, thereby improving the load-bearing capacity of the cantilever, thereby achieving the effect of supporting and protecting the cantilever, and preventing the cantilever from bending or being damaged due to hanging heavy objects.
[0019] In this embodiment, a plurality of bolts 7 are fixedly connected to the fixing plate 6, and a connecting plate 9 is fixedly connected to the end of the support plate 8 facing away from the fixing plate 6, that is, the fixing plate 6 can be fixed to the wall by a plurality of bolts 7, and then the cantilever is pulled by the suspension rope 5 to share the gravity of the heavy objects suspended by the cantilever, thereby providing support and protection for the cantilever.
[0020] In this embodiment, a screw rod 10 is connected to the fixing plate 6 and the connecting plate 9 for rotation, and the screw rod 10 is threadedly connected to the sleeve 11; the end of the screw rod 10 passes through the connecting plate 9, and when adjustment is required, the rotation of the screw rod 10 can be achieved by using a tool to rotate the protruding end of the screw rod 10 or the rod body of the screw rod 10 close to the wall.
[0021] In this embodiment, the housing 13 is a hollow structure, the rotating shaft 14 passes through the housing 13 , and one end of the rotating shaft 14 is rotatably connected to the inner wall of the housing 13 .
[0022] In this embodiment, one end of the rotating shaft 14 located inside the outer shell 13 is fixedly connected to a worm gear 15, and the sling rope 5 is wound around the rotating shaft 14. The sling rope 5 is wound around the rotating shaft 14, so the number of turns of the sling rope 5 wound around the rotating shaft 14 can be changed by rotating the rotating shaft 14 to adjust the length of the sling rope 5 between the sliding sleeve 11 and the connecting block 1, so that the sling rope 5 can adapt to different height differences between the sliding sleeve 11 and the connecting block 1.
[0023] In this embodiment, a rotating rod 16 is rotatably connected to the inner wall of the outer shell 13, and a worm 17 is fixedly connected to the rotating rod 16. The worm 17 is meshed with the worm wheel 15, and one end of the rotating rod 16 passes through the outer shell to form a handle. Since the meshing of the worm wheel 15 and the worm 17 has a self-locking effect, the number of turns of the sling 5 on the rotating shaft 14 can only be achieved by rotating the rotating rod 16 to drive the rotating shaft 14 to rotate.
[0024] In this embodiment, the two insertion rods 2 are respectively fixedly connected to the two side edges of the connecting block 1, and the two insertion rods 2 are symmetrically arranged on the connecting block 1, so that the connecting block 1 can be placed just at the end of the I-beam cantilever, so that the two insertion rods 2 are inserted into the two sides of the I-beam cantilever, thereby fixing the connecting block 1 on the cantilever.
[0025] In this embodiment, the connecting block 1 is moved to the outward end of the I-beam cantilever, and the two plug rods 2 are inserted into the two sides of the I-beam cantilever, so that the two plug rods 2 together with the connecting block 1 are stuck on the I-beam cantilever, and then the fixing plate 6 is fixed to the wall by bolts 7. At this time, the connecting block 1 and the plug rod 2 are pulled by the suspension rope 5 above the connecting block 1. When a heavy object is hung on the cantilever, the gravity will be dispersed to the sliding sleeve 11 through the suspension rope 5, so the load-bearing capacity of the cantilever is improved. Since the lengths of the cantilever are different, in order to facilitate the support and protection of cantilevers of different lengths, the screw rod 10 can be rotated. The rotation of the screw rod 10 can make the sliding sleeve 11 slide on the support plate 8, so that the end of the suspension rope 5 located on the connecting block 1 is fixed, and the end of the suspension rope 5 located below the sliding sleeve 11 can move with the movement of the sliding sleeve 11, so as to keep the suspension rope 5 as close as possible. In the vertical downward direction, the height difference between the fixing plate 6 and the connecting block 1 in the vertical direction will change the required length of the lifting rope 5. According to the height difference between the two, the length of the lifting rope 5 can be adjusted. The specific operation is to rotate the rotating rod 16 located on the outer shell 13. The rotation of the rotating rod 16 will drive the worm 17 in the outer shell 13 to rotate, and the worm 17 will then drive the worm wheel 15 meshing with it to rotate. The rotation of the worm wheel 15 drives the rotating shaft 14 to rotate, thereby changing the number of turns of the lifting rope 5 wound on the rotating shaft 14, thereby changing the length of the lifting rope 5 between the sliding sleeve 11 and the connecting block 1 to adapt to different height differences between the connecting block 1 and the sliding sleeve 11. Since the meshing of the worm wheel 15 and the worm 17 has a self-locking effect, the number of turns of the lifting rope 5 on the rotating shaft 14 can only be achieved by rotating the rotating rod 16 to drive the rotating shaft 14 to rotate.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
