Detailed Description

Example 1: when construction operation is carried out on the interior of a certain environment-friendly chimney, a vertical pipe overhead operation suspension device needs to be installed firstly for facilitating operation and ensuring the safety of constructors.

Firstly, a circle of 8# channel steel is welded in the environment-friendly chimney to serve as suspension points, and the distance between the suspension points is 1.5 m.

The overhead working suspension device for the manufacturing pipe comprises a frame body, a plate 8 and a plate fixing piece 9, wherein the frame body comprises a first section bar 1, a second section bar 2, a third section bar 3, a hook 4, a supporting plate 5, a safety rod 6 and a safety ring 7, and the first section bar 1, the second section bar 2 and the third section bar 3 are all made of 30 x 3 steel angles; a hook 4 is welded on the outer side of the top of the first section bar 1, and a through bolt hole is formed in the hook; one end of the second section bar 2 is vertically welded at the middle part of the inner side of the first section bar 1, the other end of the second section bar is welded with one end of the third section bar 3, the other end of the third section bar 3 is welded on the supporting plate 5, the non-welding surface of the supporting plate 5 and the gravity center of the hook 4 are positioned on the same vertical line, the reinforcing plate 11 is welded between the first section bar 1 and the supporting plate 5, and the first section bar 1, the second section bar 2 and the third section bar 3 form a right triangle; a vertical safety rod 6 is welded at the intersection point of the second section bar 2 and the third section bar 3, the safety rod 6 is a DN45 pipe with the length of 1.5 m, and a safety ring 7 is welded at the top of the safety rod 6.

A plurality of frame bodies are hung on the hanging points through the hooks 4, and bolts penetrate through bolt holes in the hooks 4 to fix the frame bodies; the plates 8 are placed on the second sectional materials 3 of the plurality of frame bodies in an end-to-end staggered stacking mode, the plates 8 in the embodiment are grid plates, and finally a closed circular path consistent with the circumference of the inner ring of the environment-friendly chimney is formed; the two stacked plates 8 are fixed by a plate fixing member 9, in this embodiment, a throat hoop is selected, and the plate fixing member 9 is also used to fix the grid plate and the frame body to each other.

When the worker is in construction, the worker can stand on the grid plate to operate, and the safety rope on the body is hung and buckled on the safety ring, so that the safety is easily improved.
