Furthermore, an anti-skid plate is welded on the upper side of the other end of the supporting rod and is made of a pattern steel plate, and the length of the anti-skid plate is L4 compared with the length of the supporting rod L2: L4/L2=0.54 ~ 0.56.
Further, the ratio of the height H of the middle rib plate to the pipe diameter D of the middle ship is as follows: H/D =1.9 ~ 2.1.
The utility model discloses simple structure, low in manufacturing cost need not demolish and lift by crane wire rope, also need not use the manual work, just can once only directly dock rain sewage pipe in place. The influence of the steel wire rope on the insertion joint of the rainwater and sewage pipe is reduced, the installation efficiency of the rainwater and sewage pipe is obviously improved, and a safety hole in the installation process is blocked.
The advantages and features of the invention will be illustrated and explained by the following non-restrictive description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is an enlarged left side view of fig. 1.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 and fig. 2, the pipe culvert segment lifting appliance of the present embodiment is in a U shape lying down, and includes a limiting rod 1, a supporting rod 2, a middle rib plate 3, 2 connecting plates 4, 2 rod end rib plates 5, and 2 lifting lugs 6, the limiting rod 1 and the supporting rod 2 arranged in parallel are parallel and level at the left end, and the limiting rod length L1 is smaller than the supporting rod length L2, the limiting rod length L1=1500mm, the supporting rod length L2=1800mm, and the limiting rod 1 and the supporting rod 2 are all made of steel pipes of phi 150 × 20mm with the material grade of Q235B. The parallel and level end both sides of the left end of gag lever post 1 and bracing piece 2 are welded with the upper and lower end vertical fixation of connecting plate 4 respectively in fig. 1, and between well gusset plate 3 embedding gag lever post and the bracing piece, the upper and lower end of well gusset plate 3 is welded with 1 downside of gag lever post and 2 upsides of bracing piece respectively, and such structure has improved the utility model discloses an intensity.
