DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example: See Figure 1-4 The utility model provides a construction platform for a special-shaped tower column, comprising a bottom mesh plate 1 for construction workers to stand on, two fences 2 for protecting the construction workers and a retracting mechanism 3 for retracting the construction platform, the fences 2 are arranged on the bottom mesh plate 1, the retracting mechanism 3 is arranged on the fences 2, two towing hooks 4 and two hooks 5 are symmetrically arranged at both ends of the bottom mesh plate 1, the towing hooks 4 and the hooks 5 can be hung on the buckle brackets at both ends respectively, so that the bottom mesh plate 1 can be erected between the two buckle brackets;

[0025] The retracting and releasing mechanism 3 includes a hook 301 for hooking the construction platform, a connecting rope 302, a screw rod 303 and a plurality of nuts 304. The plurality of nuts 304 are fixedly arranged on the fence 2 and arranged in a straight line. The screw rod 303 can be threadedly connected with the plurality of nuts 304, and the screw rod 303 can be threadedly connected with more than two nuts 304 at the same time. The connecting rope 302 is fixedly arranged at one end of the screw rod 303, and the connecting rope 302 slides through the plurality of nuts 304. The hook 301 is fixedly arranged at one end of the connecting rope 302 away from the screw rod 303.

[0026] After placing the first construction platform on the buckle bracket, the second construction platform can be moved to build on the first construction platform, the towing hook 4 on the second construction platform is hung on the buckle bracket, and then the hook 301 is hooked on the bottom mesh plate 1 of the second construction platform, and the screw rod 303 on the first construction platform is rotated so that it can move on the multiple nuts 304, so that the connecting rope 302 is loosened. Since the second construction platform can rotate and fall naturally, the second construction platform can slowly rotate and fall with the buckle bracket as the axis through the connecting rope 302, which can improve safety and stability;

[0027] Among them, the two towing hooks 4 and the two hooks 5 are located at the same level, and the two towing hooks 4 are respectively staggered with the two hooks 5. When the two construction platforms are built and aligned, the hooks 5 and towing hooks 4 located on the same buckle bracket can be staggered with each other, which can ensure that the bottom mesh plates 1 on adjacent construction platforms are aligned, thereby improving safety;

[0028] In this embodiment, reference Figure 1 Two rotating plates 6 are symmetrically and rotatably arranged on the bottom mesh plate 1, and the two fences 2 are fixedly arranged on the two rotating plates 6, respectively, so that the rotating plates 6 rotate on the bottom mesh plate 1 to drive the fences 2 to fold on the bottom mesh plate 1, and the fences 2 are rotated so that the fences 2 can drive the rotating plates 6 to rotate, and then the fences 2 can be folded on the bottom mesh plate 1 after the rotating plates 6 rotate, which is convenient for folding and storing the fences 2, reducing the space occupied, and facilitating storage and transportation;

[0029] The fence 2 includes a plurality of bottom cylinders 201, a plurality of top cylinders 202 and a crossbar 203. The plurality of bottom cylinders 201 are all arranged on the rotating plate 6, the plurality of top cylinders 202 are respectively arranged at one end of the bottom cylinder 201 away from the rotating plate 6, and the plurality of crossbars 203 are fixedly arranged at one end of the plurality of top cylinders 202 away from the bottom cylinder 201. Through the combination of the bottom cylinder 201 and the top cylinder 202, the crossbar 203 can be supported at a higher height, so as to avoid the fence 2 being at a lower height and improve safety.

[0030] Among them, one end of the top tube 202 is inserted into the bottom tube 201, and a bolt 9 is arranged on the top of the bottom tube 201. The bolt 9 threadably penetrates the bottom tube 201 and the top tube 202 inside it. After the bolt 9 is separated from the bottom tube 201, the top tube 202 can slide into the bottom tube 201. After the bolt 9 is separated from the bottom tube 201 and the top tube 202, the top tube 202 can be moved and stored inside the bottom tube 201, so that the height of the cross bar 203 is reduced at this time, which is convenient for folding the bottom tube 201 through the rotating plate 6, which is convenient for storage and improves convenience;

[0031] Among them, multiple nuts 304 are respectively fixedly arranged at one end of multiple top cylinders 202 close to the cross bar 203, and the screw rods 303 and the connecting ropes 302 can slide through the multiple top cylinders 202. The nuts 304 are arranged on the top cylinders 202, which can prevent the nuts 304 from protruding too much, thereby preventing the nuts 304 from hooking the construction personnel, thereby improving safety and reducing safety hazards;

[0032] In this example, see Figure 3-4 The bottom cylinder 201 is slidably connected with the rotating plate 6, and a fixed cylinder 7 is fixedly provided on the rotating plate 6, and an insertion rod 8 is slidably provided in the fixed cylinder 7. The end of the bottom cylinder 201 away from the top cylinder 202 is fixedly connected with the insertion rod 8, and the end of the insertion rod 8 away from the bottom cylinder 201 slides through the rotating plate 6 and is plugged into the bottom mesh plate 1. The cross-sectional size of the insertion rod 8 is larger than the cross-sectional size of the bottom cylinder 201. The bottom cylinder 201 is pulled upward so that the bottom cylinder 201 can be separated from the bottom mesh plate 1. At this time, the fence 2 can be folded by the rotating plate 6, and the bottom cylinder 201 is slid downward so that the bottom cylinder 201 can push the insertion rod 8 to be plugged into the bottom mesh plate 1, so that the bottom cylinder 201 and the rotating plate 6 cannot rotate at this time, which is convenient for fixing the fence 2 and passes the safety.

[0033] Based on the above conditions, the workflow designed using this solution is as follows:

[0034] When in use, first install the first construction platform through the tower crane. After the first construction platform is built, the tower crane can be detached to build multiple construction platforms. The tow hook 4 on the second construction platform is hooked on the buckle bracket, and then the hook 301 on the first construction platform is hooked on the bottom mesh plate 1 of the second construction platform. Then, the screw 303 on the first construction platform is rotated so that the screw 303 can move from one nut 304 to another nut 304, and then the connecting rope 302 can move to the end away from the screw 303. At this time, the second construction platform is slowly rotated downward with the buckle bracket as the center under gravity until the hook on the second construction platform is hooked on the buckle bracket, and the second construction platform is completed. The construction of the first construction platform is completed, and then the bottom cylinder 201 is rotated so that it stands on the bottom mesh plate 1 after rotating through the bottom plate. At this time, the bottom cylinder 201 falls and pushes the insertion rod 8 to be plugged into the bottom mesh plate 1. Then the cross bar 203 is pulled upward to drive the top rod to move upward, and the bottom cylinder 201 and the top cylinder 202 are connected and fixed with bolts 9. The construction of the fence 2 is completed. When dismantling the construction platform, the hook 301 on the first construction platform is hooked on the bottom mesh plate 1 on the second construction platform, and the screw rod 303 is rotated to drive the connecting rope 302 to move, which can pull the bottom mesh plate 1 on the second construction platform to rotate until the bottom mesh plate 1 on the second construction platform is close to a vertical state. The second construction platform can be removed to complete the disassembly.
