[0002] The construction tower crane platform is an important facility used in conjunction with tower cranes during construction. It is generally located at the standard sections of the tower crane body, and platforms are set at certain intervals. These platforms can be used as places for construction workers to carry out tower crane maintenance, repair, and installation of wall-attached components, etc. At the same time, they can also be used as temporary storage points for material transfer.

[0003] The existing utility model with the authorization announcement number CN216141160U discloses an assembled tower crane operation platform. The tower crane is assembled through tower crane standard sections, and the assembly process is convenient. Moreover, by using different models of tower crane standard sections to assemble the tower crane, it can be applied to construction work in different scenarios. The bearing platform is used to place building materials and carry workers for building construction. A number of tower crane standard sections are connected end to end. By connecting different numbers of tower crane standard sections end to end, tower cranes of different heights can be formed, so as to be applicable to the construction of buildings of different heights. By detachably connecting the bearing platform to any one of the above tower crane standard sections, the bearing platform can be connected to different tower crane standard sections so that the bearing platform is located at different heights, facilitating construction workers to construct different heights of the building.

[0004] Adopting the above technical solution, although it is convenient for splicing and disassembly, the above technical solution lacks an overweight alarm structure, resulting in difficulty in detecting overweight in time on the platform and being prone to the risk of collapse and falling.

[0005] Therefore, those skilled in the art have provided a construction tower crane platform with an overweight alarm to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a construction tower crane platform with an overweight alarm to solve the problems raised in the above background technique.

The bottom surface of each support shell is in contact with the upper surface of the support plate. The bottom surfaces of the two elastic pads and the bottom surfaces of the two pressure sensors are both in contact with the inner bottom wall of the support shell. The alarm lamp, the loudspeaker alarm and the two pressure sensors are all electrically connected to the controller through wires. Three reinforcing ribs are fixedly connected to the bottom surface of each support plate.

Specific implementation mode

[0025] Please refer to Figure 1-7 , a construction tower crane platform with overweight alarm, including a tower crane standard section 1. Both side surfaces of the tower crane standard section 1 are fixedly connected with support plates 2. An overweight alarm platform mechanism 3 is arranged outside the tower crane standard section 1. The overweight alarm platform mechanism 3 includes a main frame 301 and a splicing frame 302. A protective door 303 is movably hinged to the front surface of the splicing frame 302. Two fastening bolts 304 are commonly threadedly connected to the inner walls of the splicing frame 302 and the main frame 301. The outer surface of the splicing frame 302 is in contact with the inner wall of the main frame 301. The bottom surface of each support shell 310 is in contact with the upper surface of the support plate 2. Three reinforcing ribs 4 are fixedly connected to the bottom surface of each support plate 2. One side surface of each reinforcing rib 4 close to the tower crane standard section 1 is fixedly connected to the outer surface of the tower crane standard section 1. By arranging the reinforcing ribs 4, the tower crane standard section 1 and the support plate 2 can be connected, thereby increasing the stability of the support plate 2 relative to the tower crane standard section 1.

[0026] A controller 306 is fixedly connected to the inner side wall of the main frame 301. A bracket 305 is fixedly connected to the upper surface of the main frame 301. An alarm light 307 and a loudspeaker alarm 308 are respectively fixedly connected to the upper surface of the bracket 305. A fixing rod 7 is fixedly connected to the upper surface of the splicing frame 302. A limiting rod 8 is fixedly connected to the upper surface of the protective door 303. By arranging the fixing rod 7, a rotating base surface can be provided for other limiting structures. By arranging the limiting rod 8, limiting can be provided for the above-mentioned limiting structures.

[0027] Two support plates 309 are fixedly connected to the bottom surface of the main frame 301. A support shell 310 is slidably connected to the outer surface of each support plate 309. A limiting block 9 is arranged above the protective door 303. The inner wall of the limiting block 9 is rotatably connected to the outer surface of the fixing rod 7. The inside of the limiting block 9 is clamped to the outer surface of the limiting rod 8. By arranging the limiting block 9, it can rotate around the outer surface of the fixing rod 7 and then be clamped to the outer surface of the limiting rod 8, thereby being able to temporarily lock the protective door 303 and the splicing frame 302.

[0028] On the inner wall of each support shell 310, two mounting bolts 311 are commonly threadedly connected to the inner wall of the support plate 309. On the outer surface of each mounting bolt 311, a mounting nut 312 is threadedly connected. On the upper surface of each support plate 2, a positioning plate 5 is fixedly connected. The outer surface of each positioning plate 5 is in contact with the inner wall of the support shell 310. By providing the positioning plate 5, it can be inserted into the support shell 310, and then when the support shell 310 is placed on the support plate 2, the position of the main frame 301 relative to the tower crane standard section 1 can be temporarily positioned.

[0029] On the bottom surface of each support plate 309, an elastic pad 313 is fixedly connected. On the inner wall of each support plate 309, a pressure sensor 314 is fixedly connected. The bottom surfaces of the two elastic pads 313 and the bottom surfaces of the two pressure sensors 314 are in contact with the inner bottom wall of the support shell 310. The warning lamp 307, the loudspeaker alarm 308 and the two pressure sensors 314 are all electrically connected to the controller 306 through wires. On the outer surface of each mounting bolt 311, a washer 6 is sleeved. The bottom surface of each washer 6 is in contact with the outer surface of the support shell 310. By providing the washer 6, it can be placed between the support shell 310 and the mounting bolt 311 and increase the contact area between the two, thereby increasing the fastening effect of the mounting bolt 311.

[0030] The working principle of the present utility model is as follows: When in use, first make the inner wall of the main frame 301 close to the outer surface of the tower crane standard section 1, then make each positioning plate 5 pass through the corresponding support shell 310, and then the mounting bolts 311 and the mounting nuts 312 fix the support shell 310 to the support plate 2. Then, use the fastening bolts 304 to fix the splicing frame 302 to the main frame 301. When there are people or other heavy objects on the main frame 301 and the splicing frame 302, due to the elasticity of the elastic pad 313, the support plate 309 slides up and down within a small range in the support shell 310. Thus, the load on the main frame 301 and the splicing frame 302 causes the support plate 309 to cooperate with the support shell 310 to squeeze the elastic pad 313 and the pressure sensor 314. Therefore, when the pressure received by the pressure sensor 314 exceeds the set value of the controller 306, the controller 306 controls the warning lamp 307 to emit warning flashing lights and the loudspeaker alarm 308 to emit warning sounds respectively, playing a role in timely detecting the overweight situation of the heavy objects on the main frame 301 and the splicing frame 302 and avoiding the collapse and fall of the main frame 301 and the splicing frame 302 relative to the tower crane standard section 1. The design of the entire tower crane platform with an overweight alarm effectively solves the problem that it is difficult to be detected in time when the platform is overweight due to the lack of an overweight alarm structure, and there is an easy risk of collapse and fall.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
