Embodiment 1

[0042] An electric pole straightening device for electric power engineering construction, comprising a base 3 arranged around an electric pole 2, a jacking device 4 arranged on the base 3, a clamping device 6 arranged on the electric pole 2, adjacent bases The base 3 is vertically arranged, the base 3 is provided with a first hinge 35, the base 3 is installed on the ground 1, the clamping device 6 includes two groups of arc-shaped hoops 61, and the two groups of The hoop 61 is connected by a fastener 63, and the fastener 63 includes a fastening bolt and a fastening nut. In order to facilitate the quick disassembly and assembly of the hoop 61, the fastening nut is a wing nut; the inside of the hoop 61 A wedge 64 is provided, the outer surface of the wedge 64 is in contact with the hoop 61, and the inner surface of the wedge 64 is in contact with the electric pole 2, which greatly increases the contact area between the electric pole 2 and the hoop 61, thereby ensuring that the el...

Embodiment 2

[0052] The difference from Embodiment 1 is that in this embodiment, the calibration device includes a first connecting rod 65 installed inside the third joint 62, a flexible hanging rope 66 with one end wound on the first connecting rod 65, The other end of the hanging rope 66 is connected with a lead pendant 67. When the hanging rope 66 is parallel to the axis of the electric pole 2, the electric pole 2 is righted in place, and the hanging rope 66 with the lead pendant 67 is used to judge that the electric pole 2 is righted. degree, convenient and quick, and low cost.

Abstract

The invention discloses an electric pole straightening device for electric power engineering construction, which comprises a base arranged around the electric pole and perpendicular to each other, a jacking device arranged on the base, a clamping device arranged on the electric pole, the base There is a first joint on the top, the base is installed on the ground, and the clamping device includes two sets of arc-shaped hoops, which are connected by fasteners; the inside of the hoops is provided with wedges, and the outer surface of the wedges It is in contact with the hoop, and the inner surface of the wedge is in contact with the pole; there are several third joints on one side of the hoop; the jacking device includes a jacking cylinder, and the cylinder seat of the jacking cylinder is movably connected with the first joint. One end of the lifting oil cylinder is connected with an adjustment rod, and one end of the adjustment rod is movably connected with the third joint. In the present invention, a wedge is arranged inside the hoop, the outer surface of the wedge is in contact with the hoop, and the inner surface of the wedge is in contact with the pole, which greatly increases the contact area between the pole and the hoop, thus ensuring the righting construction of the pole safety.

Description

technical field [0001] The invention belongs to the technical field of electric power construction, and in particular relates to an electric pole straightening device for electric power engineering construction. Background technique [0002] Due to various reasons, the utility poles installed outdoors often have the problem of tilting the utility poles. The tilting of utility poles is one of the main causes of power grid blackout accidents, and it is also a major hidden danger that threatens personal safety. In the past, the straightening of utility poles relied entirely on manpower. At present, the methods of righting cement electric poles include artificial positive pole method, crane ejector pole method, and hydraulic pressure positive pole method; Insufficiencies such as high-altitude operations and necessary power outages; in the crane ejector method, there are disadvantages such as high mechanical costs for using large cranes, excessive force on the positive pole of ...
