Description

The method of transporting and erecting utility poles to the hillside

technical field

The invention relates to handling and erecting utility poles, in particular to a method for transporting and erecting utility poles to a hillside.

Background technique

The utility pole is one of the important infrastructures for power supply and communication. During installation, it is necessary to transport the utility pole to the utility pole hole and bury the utility pole vertically into the utility pole hole. Since the utility poles are usually prefabricated with reinforced concrete, the weight is relatively heavy. In the process of handling and erecting utility poles, especially in the case where vehicles and horses cannot go up the mountain on steep hills, a large number of workers are employed for manual handling and erection of utility poles. High labor intensity, long operation time and low operation efficiency.

SUMMARY OF THE INVENTION

In order to solve the above-mentioned technical problems, the present invention provides a method for transporting and erecting utility poles on a hillside, which can greatly reduce the number of employees, reduce labor intensity, and shorten the process of transporting and erecting utility poles on a steep hillside. work time and improve work efficiency.

The technical solution of the present invention is:

The method for carrying and erecting utility poles to the hillside is characterized in that the specific steps are as follows:

1), install the first ground anchor and the winch at the foot of the hill, fix the sliding line on the first ground anchor, and fix the pull rope on the drum of the winch;

2) The operator pulls the free end of the sliding line and the free end of the pulling rope, carries the second ground anchor and the first movable pulley to the top of the hill;

3) Fix the second ground anchor on the top of the hill, fix the free end of the sliding line on the second ground anchor, and tighten it;

4), pass the free end of the pull rope through the top of the second ground anchor and fix it with the first movable pulley, hook the first movable pulley on the sliding line, and fall to the foot of the hillside under the action of gravity of the first movable pulley;

5), fix the top end of the utility pole with the first movable pulley and the free end of the pull rope respectively, and hook the second movable pulley below the first movable pulley on the sliding line, and fix the bottom end of the utility pole with the second movable pulley;

6), start the hoist, and pull the pole to the top of the pole hole through the pull rope;

7), untie the second movable pulley, so that the bottom end of the utility pole hangs down to the hole of the utility pole pothole;

8), untie the first moving pulley, the bottom end of the telephone pole automatically falls into the bottom of the pole hole, and the pole is buried and fixed;

9) Send the second ground anchor, the first movable pulley and the second movable pulley back to the foot of the hillside, and retract the sliding line and the pulling rope at the foot of the hillside.

Further preferably, the first ground anchor is located between the hillside and the hoist.

Further preferably, the vertical height between the hole of the utility pole pothole and the sliding line is less than the height of the utility pole, and when the second movable pulley is unfastened, it is ensured that the bottom end of the utility pole falls into the hole of the utility pole pothole.

Further preferably, a fixed pulley is installed on the second ground anchor, and the pulling rope is bypassed by the fixed pulley.

The beneficial effects of the present invention are:

Due to the tightening of the sliding line installed between the top of the mountain and the hillside, the utility pole is hooked on the sliding line through the first movable pulley and the second movable pulley. Pull it to the top of the pothole on the telephone pole on the hillside, and then release the second moving pulley, so that the bottom end of the telephone pole hangs down to the mouth of the pothole of the telephone pole, untie the first moving pulley, and the bottom end of the telephone pole automatically falls into the bottom of the pothole of the telephone pole. Finally, the utility poles are buried and fixed, which replaces the traditional method of manually moving to the hillside and erecting utility poles, which greatly reduces the number of employees, reduces labor intensity, shortens operation time, and improves operation efficiency.

Detailed ways

As shown in Figure 1, the method of transporting and erecting utility poles to the hillside, the specific steps are as follows:

1), the first ground anchor 1 and the winch 2 are fixedly installed at the foot of the hillside, the first ground anchor 1 is located between the hillside and the winch 2, the slide line 3 is fixed on the first ground anchor 1, and the roll of the winch 2 is fixed. The pull rope 4 is fixed on the cylinder;

2), the operator pulls the free end of the sliding line 3 and the free end of the pulling rope 4, carries the second ground anchor 5, the first movable pulley 6 and the fixed pulley 7 to the top of the hill;

3), the second ground anchor 5 is fixedly installed on the top of the hillside, the free end of the sliding line 3 is fixed on the second ground anchor 5, and tightened, so that the vertical connection between the hole 10 of the pole hole and the sliding line 3 is made. The height is less than the height of the utility pole;
