The invention relates to the technical field of electric power facility protection, in particular to an electric pole fixing device with an anti-freezing and anti-pulling function in a severe cold area. The technical problem that a large amount of manpower and material resources are wasted due to the fact that an electric pole is excavated and re-buried every several years when pulled up at the present stage is solved. According to the technical scheme, the electric pole fixing device with the anti-freezing function in the severe cold area comprises an electric pole, an anti-upward-pulling mechanism is arranged on the electric pole, and a fixing anti-loosening mechanism is arranged in the anti-upward-pulling mechanism. Through the fixing anti-loosening mechanism, the trend that the three fixing supporting legs drive the fixing shell to be pulled upwards is slowed down, the fixing supporting legs are limited, the counteracting force of the three fixing supporting legs on the frost heaving force of frozen soil is improved, and the situation that the three fixing supporting legs are pulled upwards under the influence of the frost heaving force generated by the frozen soil, the fixing shell and the sleeve are inclined, and consequently an electric pole is inclined is avoided.

本发明涉及电力设施防护技术领域，尤其涉及一种严寒地区具有防冻拔功能的电杆固定装置。针对现阶段对于电杆上拔都是隔几年挖开重埋，浪费了大量的人力物力的技术问题。通过以下技术方案解决：一种严寒地区具有防冻拔功能的电杆固定装置，包括有电杆，电杆上设有防上拔机构，防上拔机构内设有固定防松机构。本发明通过固定防松机构，减缓三个固定支腿带动固定壳体上拔的趋势，对固定支腿进行限位，提高三个固定支腿对冻土冻胀力的抵消力，避免三个固定支腿在冻土产生的冻胀力影响下上拔，致使固定壳体和套筒倾斜，从而导致电杆倾斜。
