When installing cross arms and porcelain bottles on cement poles, it is usually necessary to lift the top of the pole to a certain height. The traditional manual lifting method requires multiple people to cooperate and is time-consuming and labor-intensive.

[0018] This embodiment provides a portable conical cement pole lifting and hoisting device, which can facilitate the lifting of the conical cement pole.

[0019] See also Figure 1-Figure 3 In this embodiment, a portable conical cement pole lifting and hoisting device includes a bracket 10, a swing arm 20 and an adjusting rod 30; wherein the swing arm 20 is rotatably connected to the bracket 10, a sling 21 is provided at the movable end of the swing arm 20, a slider 23 is clamped inside the swing arm 20, and the slider 23 is hinged to a telescopic mechanism 11 hinged on the bracket 10; the adjusting rod 30 is penetrated inside the swing arm 20, and reinforcing rods 31 are evenly distributed on the outer periphery of the adjusting rod 30, the reinforcing rods 31 are parallel to the adjusting rod 30, and the reinforcing rods 31 and the adjusting rod 30 are both penetrated on the slider 23, and the rotation of the adjusting rod 30 can drive the slider 23 to move along the swing arm 20.

[0020] By adopting the technical solution of this embodiment, the swing arm 20 swings upward under the drive of the telescopic mechanism 11, and can lift the conical cement pole inserted in the sling 21; by rotating the adjusting rod 30, the slider 23 can be driven to move along the swing arm 20, thereby changing the connection position between the telescopic mechanism 11 and the swing arm 20; by evenly arranging multiple reinforcing rods 31 on the periphery of the adjusting rod 30, the overall structural strength of the swing arm 20 can be effectively enhanced.

[0021] In this embodiment, a moving wheel 12 is provided at the bottom of the bracket 10, so that the overall movement of the bracket 10 is more convenient and labor-saving. The left end of the swing arm 20 is hinged to the top of the bracket 10, and the fixed end of the telescopic mechanism 11 is hinged to the lower middle part of the bracket 10. The movable end of the telescopic mechanism 11 is hinged to the slider 23. The telescopic mechanism 11 can drive the swing arm 20 to swing around the hinge axis at its left end through the extension and contraction of the telescopic mechanism 11. The telescopic mechanism 11 includes a jack. Of course, the telescopic mechanism 11 can also use a hydraulic telescopic cylinder or a pneumatic telescopic cylinder.

[0022] In this embodiment, the swing arm 20 is constructed as a rectangular tube as a whole, and the interior of the swing arm 20 has an inner cavity with a rectangular cross-section. Two parallel avoidance grooves 22 are opened on the lower side wall of the swing arm 20, and the extension direction of the avoidance grooves 22 is parallel to the longitudinal direction of the swing arm 20.
