[0034] In the embodiment of the present utility model, the shape of the trapezoidal fastening seat 5 is a right trapezoid, and its inclined surface faces the inside of the right-angle frame 1. Furthermore, the outer end of the H-shaped steel column can be extruded by the inclined surface of the trapezoidal fastening seat 5 and the inner surface of the right-angle frame 1, enabling the device to be quickly fixed on the H-shaped steel column, effectively ensuring the stability of the fixation and avoiding the situation that the safety rope is not firmly fixed due to its shaking.

[0035] In the embodiment of the present utility model, the setting of the wear-resistant soft pad 4 can increase the contact friction when the right-angle frame 1 and the strip frame 6 contact the outer surface of the H-shaped steel, ensuring the stability of the device fixation.

[0036] The fastening frame 7 is arranged at one end of the strip frame 6 and is in movable contact with the strip frame 6. One end of it is provided with a fastening threaded hole 71, and it is provided with the same trapezoidal fastening seat 5 as that on the right-angle frame 1; the fastening adjustment screw rod 8 is located between the two fastening frames 7 and is threadedly connected with the fastening threaded hole 71; the fastening handle 9 is arranged at one end of the side surface of the fastening frame 7, movably passes through the fastening frame 7, and is movably installed on the fastening frame 7 through two embedded limit baffles 91.

[0037] In the embodiment of the present utility model, by threadedly connecting the fastening adjustment screw rod 8 with the fastening frame 7, the distance between the two fastening frames 7 can be adjusted to match the position of the strip frame 6, thus facilitating the fixation of the device and also meeting the fixation of the device on H-shaped steel columns of different sizes.

[0038] In the embodiment of the present utility model, by threadedly connecting the fastening handle 9 with the strip frame 6, the fixation speed of the device can be increased. At the same time, its fastening method is simple and fast, effectively improving the disassembly and assembly efficiency.

[0039] In the present utility model, the inclined surface of the trapezoidal fastening seat 5 is in movable contact with the wear-resistant soft pad 4; ensuring that the distance between the inclined surface of the trapezoidal fastening seat 5 and the inner wall of the right-angle frame 1 is not too large, so that the device can be extruded and fixed with the outer end of the H-shaped steel column.

[0040] In this utility model, the distance between the lower end of the inclined surface of the trapezoidal fastening seat 5 and the right-angle frame 1 is less than the thickness of the wear-resistant soft pad 4, and the distance between the upper end of the inclined surface of the trapezoidal fastening seat 5 and the right-angle frame 1 is greater than the thickness of the H-shaped steel column; ensuring that the trapezoidal fastening seat 5 can extrude the outer end of the H-shaped steel column, improving the extrusion force, and ensuring the firmness of the device fixed on the H-shaped steel column.

[0041] In this utility model, the fastening handle 9 is threadedly connected to one end of the strip-shaped frame 6; enabling the device to be quickly connected and fastened, improving the installation efficiency.

[0042] In this utility model, hooks 12 are provided on the outer surfaces of the right-angle frame 1, the strip-shaped frame 6, and the fastening frame 7; facilitating the hanging of the safety rope and enabling the safety rope to be quickly hung.

[0043] In this utility model, the trapezoidal fastening seat 5 is extrusion-fitted inside the H-shaped steel column; enabling the trapezoidal fastening seat 5 to extrude the inner side of the outer end of the H-shaped steel column, thereby ensuring the stability of the fixation.

[0044] When specifically using this device, the staff takes out the device, measures the size of the H-shaped steel column, and then adjusts the size of the U-shaped frame formed by the strip-shaped frame 6 - right-angle frame 1 - right-angle frame 1 - strip-shaped frame 6 according to the size of the H-shaped steel column.

[0045] By respectively rotating the two right-angle frames 1 and using tools to fix the right-angle adjusting screw 2, the staff can adjust the distance between the two right-angle frames 1;

[0046] By rotating the strip-shaped frame 6 and the length adjusting screw 3 and manually controlling the right-angle frame 1 to remain stationary, the distance between the right-angle frame 1 and the strip-shaped frame 6 can be adjusted;

[0047] When the adjustment of this U-shaped frame is completed, the staff takes out the fastening frame 7, and by respectively rotating the two fastening frames 7 and simultaneously using tools to fix the fastening adjusting screw 8, the distance between the two fastening frames 7 can be adjusted;

[0048] When the device adjustment is completed, the U-shaped frame can be sleeved on the H-shaped steel column at this time, making the side frame where the strip-shaped frame 6 is located对接 with the two panels of the H-shaped steel, and making the trapezoidal fastening seat 5 inside the right-angle frame 1 contact the outer end of the H-shaped steel column.
