DETAILED DESCRIPTION

[0019] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: a fixed suspension device on an H-shaped steel beam, comprising a floor slab 1 and a fixed suspension device 3, wherein an H-shaped steel beam 2 is fixedly connected to the bottom of the floor slab 1, and the fixed suspension device 3 is arranged at the bottom of the H-shaped steel beam 2.

[0021] The fixed suspension device 3 includes an outer shell 4, which adopts a box-shaped metal structure with a half-open upper surface and front and rear sides (three sides in total), and the half-open area is the upper half, so that the lower flange of the H-shaped steel beam 2 can be inserted into the outer shell 4 through the half-open area.

[0022] A sliding plate 5 is slidably connected inside the shell 4, a pad 7 is fixedly connected to the top of the sliding plate 5 and the top of the shell 4, a connecting rod slide plate 6 is fixedly connected to the bottom of the sliding plate 5, and a plurality of connecting rod slide plates 6 are provided. A strip groove is provided on the connecting rod slide plate 6, and an upper connecting rod 8 and a rotating bolt 10 are provided in the strip groove. A plurality of upper connecting rods 8 are provided. The upper connecting rod 8 is connected to the connecting rod slide plate 6 through the rotating bolt 10. A fixed rod 16 is fixedly connected to the center of the bottom of the shell 4, and a rotating shaft 11 is provided on the fixed rod 16. The middle of the two groups of upper connecting rods 8 are connected to the rotating shaft 11 in a sleeve shape. A rotating bolt 2 18 and a lower connecting rod 15 are provided at the bottom of the upper connecting rod 8. The lower connecting rod 15 is connected to the upper connecting rod 8 through the rotating bolt 2 18, and a rotating shaft 2 17 and a lower hanging are provided at the bottom of the lower connecting rod 15. The lower connecting rod 15 is connected to the lower hanging rod 9 by the rotating shaft 2 17, and the lower hanging rod 9 is used for temporarily hanging equipment or objects. When in use, the device is put on the lower flange of the H-shaped steel beam 2, and the equipment or objects that need to be temporarily hung are hung on the lower hanging rod 9. The lower hanging rod 9 is moved downward by the dead weight of the equipment or object, and the lower connecting rod 15 is pulled downward by the rotating shaft 2 17 on the lower hanging rod 9; the lower connecting rod 15 drives the upper connecting rod 8 to rotate around the rotating shaft 11 on the fixed rod 16 through the rotating bolt 2 18 between it and the upper connecting rod 8, so that the upper angle between the upper connecting rod 8 becomes smaller, and the rotating bolt 10 at the upper end of the upper connecting rod 8 moves inward along the strip groove of the connecting rod slide plate 6, and finally lifts the sliding plate 5, so that the sliding plate 5 and the top of the shell 4 clamp the lower flange of the H-shaped steel beam 2 to play a fixing role.

[0023] A connecting rod movable gap 14 is provided at the bottom of the housing 4 , and the upper connecting rod 8 is arranged in the connecting rod movable gap 14 . The connecting rod movable gap 14 is used for allowing the upper connecting rod 8 to move freely.

[0024] The rotating shaft 11 is perpendicular to the fixed rod 16. The rotating shaft 11 and the fixed rod 16 are manufactured as an integrated whole. Except for the middle and the two ends of the rotating shaft 11, the diameter of the middle section between the fixed rod 16 and the two ends is reduced. The small diameter part is used to cover the upper connecting rod 8 to prevent the upper connecting rod 8 from moving, thereby improving the safety and connection accuracy of the device.

[0025] The second rotating shaft 17 is perpendicular to the lower hanging rod 9. The second rotating shaft 17 and the lower hanging rod 9 are manufactured as an integrated whole. Except for the middle and the two ends of the second rotating shaft 17, the diameter of the middle section between the lower hanging rod 9 and the two ends is reduced. The small diameter part is used to sleeve the lower connecting rod 15 to prevent the lower connecting rod 15 from moving, thereby improving the safety and connection accuracy of the device.

[0026] Wedge-shaped sliders 13 are fixedly connected at both ends of the sliding plate 5. Several groups of wedge-shaped sliders 13 are provided. Wedge-shaped grooves 12 are opened on both sides of the inner wall of the shell 4. The shape and position of the wedge-shaped grooves 12 match those of the wedge-shaped sliders 13, so that the wedge-shaped sliders 13 are slidably connected to the shell 4.

[0027] Working principle:

[0028] When in use, tilt at a certain angle, put the fixed hanging device 3 on the lower flange of the H-shaped steel beam 2 through the half-open area, and straighten the shell 4 so that the top of the shell 4 is in contact with the lower flange of one side of the H-shaped steel beam 2; then hang the equipment or objects that need to be temporarily suspended on the lower hanging rod 9, use the dead weight of the equipment or object to make the lower hanging rod 9 move downward, and pull the lower connecting rod 15 downward together through the rotating shaft 2 17 on the lower hanging rod 9; the lower connecting rod 15 drives the upper connecting rod 8 to rotate around the rotating shaft 11 on the fixed rod 16 through the rotating bolt 2 18 between it and the upper connecting rod 8, so that the upper angle between the upper connecting rod 8 becomes smaller, and the rotating bolt 10 at the upper end of the upper connecting rod 8 moves inward along the strip groove of the connecting rod slide plate 6, and finally lifts the sliding plate 5, so that the sliding plate 5 and the top of the shell 4 clamp the lower flange of the H-shaped steel beam 2, so that the fixed hanging device 3 is temporarily and reliably fixed on the lower flange of the H-shaped steel beam 2.

[0029] After use, remove the equipment or object, lift the lower hanging rod 9 upward by hand, drive the whole mechanism to move, so that the sliding plate 5 descends, the fixed hanging device 3 and the lower flange of the H-shaped steel beam 2 are loosened, and the recovery device is convenient and easy.
