[0002] Tower crane is a kind of engineering machinery widely used on construction sites, used for vertical transportation and installation of high-rise buildings. The structure of tower crane mainly consists of tower body, tower head, tower arm, balance arm, lifting mechanism, slewing mechanism, tower top and tower base. The working principle of tower crane is to lift the heavy objects to the specified height through the lifting mechanism, and then transport the heavy objects to the specified position through the slewing mechanism.

[0003] Before using a tower crane, a person needs to climb up to the cab via a tower crane ladder to operate it. Since the tower crane is high and needs to be installed with anti-fall equipment when it moves, some anti-fall equipment, such as aerial work safety belts, need to be replaced and worn many times during use, which increases the wearing time and reduces safety. Therefore, it is necessary to propose an anti-fall equipment for tower crane climbing. Utility Model Content

[0006] One ends of the two limit blocks extend through the corresponding limit holes, a second cavity is formed through the inside of the support block on one side of the first cavity, the inner walls of the two second cavities are slidably connected with T-shaped top blocks, and one ends of the two T-shaped top blocks extend through the first cavity on the same side, and a third cavity is formed through the middle of the support block;

[0007] One ends of the two second cavities extend into the third cavity, the inner wall of the third cavity is slidably connected with a pull block, the lower surface of the pull block is fixedly connected with a pull rope, and one end of the pull rope extends through a hole to the outside of the support block and is fixedly connected with a safety strap.

[0008] Wherein, the outer walls of one end of the two limit blocks located in the first cavity are fixedly connected with the first spring, and the other ends of the two first springs are fixedly connected to the support block.

[0009] Wherein, the outer walls of one end of the two T-shaped top blocks located in the second cavity are fixedly connected with a second spring, and the other ends of the two second springs are fixedly connected to the support block.

[0010] Wherein, the outer walls of the two T-shaped top blocks at one end of the pulling block are fixedly connected with auxiliary support blocks, and the two auxiliary support blocks are against the pulling block.

[0011] Wherein, the two auxiliary support blocks are both arranged in a trapezoidal shape.

[0012] Among them, several of the limiting holes and limiting blocks are arranged in a triangular shape.

[0013] Compared with the prior art, the beneficial effect of the utility model is that when a person moves up and down at the climbing ladder, the person drives the support block up and down by the pull rope, and the first spring pushes the limit block to move into the limit hole to fix the support block.

The elastic force of the first spring 12 is smaller than the elastic force of the second spring 13, which makes it convenient to use the second spring 13 to push the T-shaped top block 7 to move in the second cavity 6.
