[0013] Example 1: A certain project needs to erect a cement pole on a hillside, the operating personnel have dug a pole hole in advance, and the pole is transported to the side of the pole hole. Then, a pole erecting device for a cement pole is used to erect the pole, which includes a flange 1, a support leg 3, a fixed pulley 2, and a hand winch 6. The flange 1 is made of a circular steel plate with a thickness of 12 mm. Three 12 mm steel plates are evenly welded to the bottom surface of the flange 1 to form hinged lugs 7, which are arranged in a circular array around the center of the flange 1 with an angle of 120° between them. A hook is arranged at the center of the bottom surface of the flange 1, and a fixed pulley 2 is hung from the hook. The top of the support leg 3 is hinged to the hinged lugs 7. The support leg 3 is divided into two sections, and a limiting ring 5 is welded inside the connection between the two sections. The two sections are connected by a hoop 4 that is fastened by bolts outside. The support leg 3 is made of φ159×4.5 steel pipe, and the total length of the support leg 3 is 7 m, with each section being 3.5 m long. The hand winch 6 is fixed to the lower part of any support leg 3. The steel rope inside the hand winch 6 is φ10 mm, 6×37 fiber core steel wire rope. The hand winch 6 has a gear set and a locking device. The gear set is used to reduce the hand wheel torque, and the locking device can ensure that the drum is locked when no force is applied to the hand wheel.

[0014] In use, the steel rope of the hand winch 6 is hung into the fixed pulley, and then the operating personnel stand up the device and place the support leg 3 on the ground for leveling. Since the support leg 3 is placed on the ground, the support leg 3 will sink into the ground after being stressed into place, so there is no need to set another limiting device. The pole uses a nylon sling, and the fastening position is selected at a position of 3 / 5 of the full length of the pole, near the upper part of the pole. The sling is connected to the steel rope, and the operating personnel operate the hand winch 6 to lift the pole until the root of the pole is off the ground. The pole is rotated, the root of the pole is aligned with the pole hole, and the hand winch 6 is slowly operated to lower the pole and drop it into the pole hole.
