The main function of the tower body is to provide sufficient height and stability to ensure the safety of the tower crane during operation. Therefore, there is a particular need for a tower body section for a tower crane.

[0003] However, for the existing tower body sections of tower cranes, they are generally installed with each other through bolts. However, after the tower body climbs to a certain height, due to the relatively complex connection method of bolt connection, it takes a lot of time for workers to install, resulting in low work efficiency.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a tower section for a tower crane, including a main body 1, a buckle 2 fixedly connected to the outer surface of the main body 1, a connecting mechanism 3 provided on one side surface of the main body 1, and a climbing mechanism 4 provided on the inner surface of the main body 1;

[0021] The connecting mechanism 3 includes a fixed block 301, a positioning groove 302, a first connecting block 303, a moving block 304, a positioning block 305, a second connecting block 306, a tapered groove 307, a tapered block 308, a handle 309, a pin hole 310 and a fixing pin 311. One side surface of the main body 1 is fixedly connected with the fixed block 301. A positioning groove 302 is formed on the upper surface of the fixed block 301. One side surface of the fixed block 301 is fixedly connected with the first connecting block 303. One side surface of the main body 1 is fixedly connected with the moving block 304. A positioning block 305 is fixedly connected to the lower surface of the moving block 304. One side surface of the moving block 304 is fixedly connected with the second connecting block 306. A tapered groove 307 is formed on the upper surface of the second connecting block 306. The inner surface of the tapered groove 307 is slidably connected with the tapered block 308. One side surface of the tapered block 308 is fixedly connected with the handle 309. A pin hole 310 is formed on the outer surface of the handle 309. The inner surface of the pin hole 310 is slidably connected with the fixing pin 311. Through the settings of the fixed block 301, the positioning groove 302, the first connecting block 303, the moving block 304, the positioning block 305, the second connecting block 306, the tapered groove 307, the tapered block 308, the handle 309, the pin hole 310 and the fixing pin 311, during use, two sets of the main body 1 will be stacked together. The positioning block 305 will enter the positioning groove 302 for positioning. At this time, the first connecting block 303 and the second connecting block 306 will be perpendicular to each other. Then pick up the handle 309 and place the tapered block 308 in the tapered groove 307. A groove is formed at the top of the second connecting block 306, which fits with the handle 309, so that the handle 309 will not be placed in the wrong direction. Then insert the fixing pin 311 into the first connecting block 303 through the pin hole 310 on the surface of the handle 309. The fixing pin 311 will pass through the handle 309, the first connecting block 303, the tapered block 308 and the fixed block 301. The tapered block 308 will be stuck in the first connecting block 303 to connect the two sets of the main body 1, thus simplifying the connection method of the main body 1 and improving the installation and disassembly efficiency.

[0022] Further, multiple sets of the buckles 2 are arranged on the surface of the main body 1. The fixed block 301 is symmetrically arranged with respect to the central axis of the main body 1. Through the setting of the buckles 2, during use, the buckles 2 can be used in combination with the climbing frame to enable the tower crane to rise.

[0023] Further, the inner wall size of the positioning groove 302 matches the outer wall size of the positioning block 305. The first connecting block 303 is symmetrically arranged with respect to the central axis of the fixed block 301. Through the settings of the positioning groove 302 and the positioning block 305, during use, the positioning block 305 will enter the positioning groove 302, and the positioning groove 302 will position the positioning block 305, enabling the two sets of the main body 1 to be accurately stacked together.

[0024] Further, a tapered groove 307 is also formed on the surface of the first connecting block 303. The inner wall size of the tapered groove 307 matches the outer wall size of the tapered block 308. Through the arrangement of the tapered groove 307 and the tapered block 308, during use, the tapered block 308 can enter the tapered groove 307, and the tapered block 308 will connect the first connecting block 303 and the second connecting block 306, making the connection between the two groups of main bodies 1 more stable.

[0025] Further, the inner wall size of the pin hole 310 matches the outer wall size of the fixing pin 311. The pin holes 310 are formed on the surfaces of the tapered block 308, the first connecting block 303, and the fixing block 301. Through the arrangement of the fixing pin 311 and the pin hole 310, during use, a frictional force will be generated between the pin hole 310 and the fixing pin 311, and the fixing pin 311 will not disengage from the pin hole 310 without external force, improving the connection stability.

[0026] Further, the climbing mechanism 4 includes an inclined beam 401, steps 402, a support beam 403, and a rest board 404. The inclined beam 401 is fixedly connected to the inner surface of the main body 1. Steps 402 are fixedly connected to one side surface of the inclined beam 401. One end of the inclined beam 401 is fixedly connected to the support beam 403. The rest board 404 is fixedly connected to one side surface of the support beam 403. Through the arrangement of the inclined beam 401, steps 402, support beam 403, and rest board 404, during use, workers can gradually ascend by stepping on the steps 402 and can rest on the rest board 404. The support beam 403 and the inclined beam 401 can support the steps 402. The steps 402 placed obliquely are easier to climb than a vertically placed ladder, reducing the fatigue of workers climbing the tower body and being safer.

[0027] Further, multiple groups of steps 402 are evenly distributed on the outer surface of the inclined beam 401 at equal intervals, and multiple groups of rest boards 404 are arranged on the inner surface of the main body 1. Through the arrangement of the rest board 404, during use, the surface of the rest board 404 is light-transmitting, allowing workers below to observe the situation above, increasing the amount of information observed and reducing the occurrence of accidents.

[0028] Working principle: the two groups of main bodies 1 will be stacked together, the positioning block 305 will enter the positioning groove 302, the positioning groove 302 will position the positioning block 305, so that the two groups of main bodies 1 can be accurately stacked together, at this time the first connecting block 303 and the second connecting block 306 will be perpendicular to each other, then pick up the handle 309, place the tapered block 308 in the tapered groove 307, the tapered block 308 will connect the first connecting block 303 and the second connecting block 306, so that the connection between the two groups of main bodies 1 is more stable, the top of the second connecting block 306 is provided with a groove, which coincides with the handle 309, the handle 309 will not be put in the wrong direction, then the fixing pin 311 is inserted into the first connecting block 303 through the pin hole 310 on the surface of the handle 309, the fixing pin 311 will pass through the handle 309, the first connecting block 303, the tapered block 308 and Friction will be generated between the fixing block 301, the pin hole 310 and the fixing pin 311. In the absence of external force, the fixing pin 311 will not be detached from the pin hole 310, which improves the stability of the connection. The conical block 308 will be stuck in the first connecting block 303 to connect the two groups of main bodies 1, which simplifies the connection method of the main body 1 and improves the efficiency of installation and disassembly. After the connection is completed, the workers can gradually rise by stepping on the steps 402 and can rest on the rest board 404. The support beam 403 and the inclined beam 401 can support the steps 402. The obliquely placed steps 402 are easier to climb than the vertically placed ladder, which reduces the fatigue of the workers climbing the tower body and is safer. The surface of the rest board 404 is light-transmissive, allowing the workers below to observe the situation above, increasing the amount of information observed and reducing the occurrence of accidents.
