Detailed ways

As shown in Figures 1 to 4, a pipeline ditch device includes multiple sets of folding rods 3 and multiple groups of retracting and pulling devices 2, and two adjacent groups of folding rods 3 are connected by multiple connecting rods 9; the folding rods 3 includes a fixed rod 31 and an oblique rod 32 with one end hinged on one end of the fixed rod 31, the fixed rod 31 is fixed on the ground through a plurality of steel drills 8; The retracting device 2 includes a chain hoist 21 and a wire rope 22, the hook of the chain hoist 21 is detachably connected to one end of the fixed rod 31, the hook of the chain hoist 21 is connected to one end of the wire rope 22 through a shackle, and the other end of the wire rope 22 is connected through the shackle It is detachably connected with the fixed rod 31.

The using method of the present utility model is:

When it is necessary to lower a pipe above ground into a trench:

The first step: the worker connects the folding rod 3 and the connecting rod 9 together by screws, then takes the steel drill 8, fixes the fixed rod 31 on the ground, and puts one end of the inclined rod 32 into the ditch.

Step 2: After the worker rolls the pipe onto the fixed rod 31, install the chain block 21 and the steel wire rope 22 on the fixed rod 31, use the steel wire rope 22 to wind the pipe, roll the pipe, and release the chain block 21;

Step 3: Slowly roll the pipe onto the inclined rod 32. At the same time, two workers hold the two ends of the pipe respectively in the ditch to prevent the pipe from deflecting. Multiple workers on the ground simultaneously release the handles The gourd 21 allows the pipeline to slowly drop into the ditch along the inclined rod 32, and finally takes out the steel wire rope 22 rope, so far the pipeline is lowered and completed.

When the pipeline in the ditch needs to be lifted to the ground: after the device is assembled, the steel wire rope 22 can be wound around the pipeline, and the chain hoist 21 can be used to lift the pipeline to the ground.

It also includes a plurality of supporting plates 4, and each supporting plate 4 is respectively hinged on the end of each folding rod 3 away from the connecting rod 9. The support plate 4 can expand the contact surface with the bottom of the ditch, preventing one end of the folded rod 3 from sinking into the soil in the ditch when carrying the pipeline.

A slot 33 for accommodating the wire rope 22 is provided on each folding rod 3 . When lowering or lifting the pipeline, one end of the wire rope 22 can be put into the slot 33, and the slot 33 is used to limit the wire rope 22 to prevent the wire rope 22 from deflecting.

Two pulleys 7 for overlapping steel wire ropes 22 are installed on the hinge shaft where the flap is hinged with the fixed rod 31 . The pulley 7 is used to avoid the dry grinding of the wire rope 22, prolong the service life of the wire rope 22, and also reduce friction, making it easier for the worker to pull the chain hoist 21.

It also includes a support base 5, the support base 5 is detachably connected to one end of the fixed rod 31 through screws, and the chain hoist 21 and the wire rope 22 are detachably connected to the support base 5 through two shackles. Support base 5 can be conveniently installed to wire rope 22 and gourd, after the workman rolls pipeline on the fixed rod 31, just can support base 5 be installed on the fixed rod 31, and then steel wire rope 22 and gourd are installed.

It also includes a plurality of slanting blocks 6, and each slanting block 6 is respectively placed on one end of each fixing rod 31. When it is necessary to roll the pipeline onto the fixed rod 31, each block 6 can be placed on one end of the fixed rod 31 to form a slope on one side of the fixed rod 31, so that the pipeline can be easily rolled to the fixed rod 31. on rod 31.
