Background Technique

[0002] With the shorter construction period requirements in the metallurgical industry, the work efficiency requirements for equipment installation in the metallurgical industry are also getting higher and higher. Among them, the hoisting work efficiency and safety of variable-diameter H-shaped roof beams in metallurgical industry factories are the key to saving human resources and time costs. During the construction process, safety protection must be carried out to prevent high-altitude falls. Generally, the method of setting up safety ropes is adopted. The traditional method of setting up safety ropes is to weld columns on the H-shaped roof beam, and there are safety rope perforations on the columns. After the construction is completed, the columns need to be cut again. The welding and cutting workload is large, increasing the physical consumption of personnel; and it may cause surface damage or even structural deformation to the H-shaped roof beam. At the same time, the welded horizontal safety rope support of the H-shaped roof beam is for one-time use, which not only wastes materials and labor, but also easily causes workers to be injured by welding and machinery. If the welding is not firm, it is also easy to cause the risk of high-altitude falls and high-altitude falling objects of high-altitude operators.

[0003] To solve the above problems, a utility model patent with the patent name: A fixed bracket for a steel structure horizontal safety rope (publication number: CN205663232U) discloses a detachable and reusable fixed bracket. However, when applying this fixed bracket to the H-shaped roof beam, this fixed bracket can only be fixed on the flange on one side of the H-shaped roof beam, and there is a risk of falling when the force is large.

It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0021] Embodiment: As shown in the attached Figures 1-4 drawing, the present utility model relates to a detachable support base for a variable-diameter H-shaped roof beam horizontal safety rope, which includes a column 2 arranged on the top of the H-shaped roof beam 1. A plurality of safety rope sockets 21 are provided on the column 2. Connecting bases 3 extending outward are provided on the left and right sides of the bottom of the column 2. The distance between the two connecting bases 3 is adjustable. A slot 4 adapted to the top flange of the H-shaped roof beam 1 is provided on one side of the connecting base 3 close to the H-shaped roof beam 1. By adjusting the distance between the two bases 3, the top flange of the H-shaped roof beam 1 can be limited within the space enclosed by the two slots 4, and the column 2 can be fixed on the H-shaped roof beam 1.

[0022] Preferably, in order to improve the firmness of the column fixation, a locking plate 41 is provided in the slot 4. An adjusting screw 42 for adjusting the height of the locking plate 41 is provided at the bottom of the connecting base 3. The adjusting screw 42 is threadedly connected to the connecting base 3. One end of the adjusting screw 42 is vertically inserted into the slot 4, and the end of the adjusting screw 42 inserted into the slot 4 is connected to the locking plate 41. The locking plate 41 can be directly welded to the adjusting screw 42, or the locking plate 41 can also be rotatably connected to the adjusting screw 42. Rotating the adjusting screw 42 can drive the locking plate 41 to move up or down. When moving up, the locking plate 41 abuts against the H-shaped roof beam 1, which can firmly connect the connecting base 3 and the H-shaped roof beam 1, and further improve the stability of the installation of the column 2.

[0023] Preferably, in order to avoid damaging the paint on the flange surface of the H-shaped roof beam, a rubber pad 43 is provided on the top of the locking plate 41. Rubber pads can also be bonded to the top surface in the slot 4 and the bottom surface of the column 2.

[0024] Preferably, to facilitate the adjustment of the distance between the two connection bases, one connection base 3 is located on the front side of the column 2, and the other connection base 3 is located on the rear side of the column 2. At one end of the connection base 3 close to the column 2, a connecting plate 31 is provided. The connecting plate 31 and the connection base 3 are of an integral structure. A waist-shaped hole 32 is horizontally provided on the connecting plate 31. A connecting bolt 22 adapted to the waist-shaped hole 32 is provided on the column 2. The connection base 3 is fixed to the column 2 through the connecting bolt 22. Loosening the connecting bolt 22 allows manual adjustment of the position of the connection base 3.

[0025] Preferably, to ensure the stability of the installation of the connection base, at least two waist-shaped holes 32 are arranged on the connecting plate 31 from top to bottom in sequence.

[0026] Preferably, to facilitate the arrangement of the safety rope, the column 2 is a channel steel, and safety rope insertion holes 21 are arranged on each side surface of the channel steel. Two through holes (safety rope insertion holes 21) for passing through the horizontal safety rope can be provided on the column channel steel. The two through holes are arranged in a vertically offset manner, which is convenient for the operator to select the pulling height of the horizontal safety rope according to the actual working height and is very practical in the working environment of high-altitude operations.

[0027] When the utility model is in use, first adjust the distance between the two connection bases 3 according to the width of the H-shaped roof beam 1, limit the top flange of the H-shaped roof beam 1 within the space enclosed by the two slots 4, and then rotate the adjusting screw 42 to adjust the position of the locking plate 41 so that the locking plate 41 is in close contact with the bottom surface of the top flange of the H-shaped roof beam 1, fixing the column 1 and the two connection bases 3 on the upper beam of the H-shaped roof beam 1 to form an integral body. Then, the two safety rope insertion holes 21 at the upper part of the column 1 are arranged in a vertically offset manner to pass through the horizontal safety rope 5, and the horizontal safety rope 5 is fixed firmly with a special buckle.
