Description

Technical Field

[0001] The utility model relates to the technical field of iron tower construction, in particular to an anti-fall protection device for iron tower construction. Background Art

[0002] Transmission line towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are spatial truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The rods are connected by rough bolts, which are connected by shear force. The entire tower is composed of angle steel, connecting steel plates and bolts. Individual components such as the tower foot are welded from several steel plates into an assembly. Therefore, hot-dip galvanizing for corrosion protection, transportation and construction and erection are extremely convenient. For towers with an elevation of less than 60m, foot nails are set on one of the main materials of the tower to facilitate construction workers to climb the tower.

[0003] During the construction of the tower, in order to ensure the safety of the construction workers, they are usually required to wear safety protection devices to prevent them from falling. Usually, the construction workers will wear personal protective safety belts and rope grabs and other facilities, and these facilities are usually worn by the construction workers before they start work. During the construction process, the construction workers will stay in a certain place for a long time. During the stay, the safety facilities they wear are still in a loose state, which reduces the safety performance of the construction workers' high-altitude operations. It is necessary to design an anti-fall protection device for tower construction to solve the above-mentioned problems. Utility Model Content

[0007] Through the above technical solution, during use, the construction workers hang the U-shaped frame on the iron tower, and then tighten the connecting screw inward in the threaded groove, so that the bottom of the U-shaped frame is in a closed state, thereby protecting the construction workers. When the construction workers need to move, they only need to unscrew the connecting screw to open the bottom of the U-shaped frame, so that the construction workers can be more cautious during operation, and the anti-fall performance of the construction workers who stay in a certain place on the iron tower for a long time is increased.

[0008] Furthermore, a rotation groove is provided in the middle of the front end of the connecting screw, a rotation column is rotatably connected to the inner side of the rotation groove, the front side of the rotation column is fixedly connected to one end of the second connecting cable, and a third safety buckle is provided at the other end of the second connecting cable;

[0009] Through the above technical solution, the connecting screw is hung on the construction worker, which prevents the risk of falling after the connecting screw is completely out of the thread groove. At the same time, when the connecting screw is rotated, the rotating column rotates in the rotating groove, which will not cause the second connecting cable to be twisted.

[0010] Furthermore, a handle is provided on the upper portion of the U-shaped frame;

[0011] The above technical solution makes it easy for construction workers to carry the U-shaped frame.

[0012] Furthermore, the middle parts of the front and rear sides of the U-shaped frame are both provided with empty slots;

[0013] By adopting the above technical solution, the overall weight of the U-shaped frame is reduced.

[0014] Furthermore, the U-shaped frame, the fixing ring, the first mounting cylinder and the second mounting cylinder are integrally formed and made of stainless steel;

[0015] Through the above technical solution, the integrated setting and the use of stainless steel material increase the structural strength, make it less prone to damage, and avoid breakage during use that causes the loss of protective performance.

[0016] According to the above technical solution, the first connecting cable and the second connecting cable are both made of steel wire rope, the thickness of the U-shaped frame is 0.4-0.7 cm, and the diameter of the fixing ring is 1.5 cm;

[0017] Through the above technical solution, the strength of the first connecting cable, the second connecting cable, the U-shaped frame and the fixing ring is increased, thereby increasing the weight they can bear.

[0018] The utility model has the following beneficial effects:

[0019] In the utility model, during the wearing process, the first safety buckle is first hung on the fixing ring, and then the second safety buckle is hung on the safety clothes worn by the construction personnel. The first safety buckle and the second safety buckle are connected by a first connecting cable and fastened. Secondly, the connecting screw and the rotating column are hung on the safety clothes worn by the construction personnel through the second connecting cable and the third safety buckle. During use, the construction personnel hang the U-shaped frame on the iron tower, and then tighten the connecting screw inward in the threaded groove to make the bottom of the U-shaped frame in a closed state, thereby protecting the construction personnel. When the construction personnel need to move, they only need to unscrew the connecting screw to make the bottom of the U-shaped frame in an open state, and then carry the U-shaped frame by pulling the handle. It is convenient to use, and the connecting screw can be installed and disassembled by hand, so that the construction personnel can be more cautious during operation, and the anti-fall performance for the construction personnel who stay at a certain place on the iron tower for a long time is increased.
