Problems solved by technology

[0003] At present, in the construction of the power grid, erecting transmission lines in the air using iron towers and poles is the main transmission method. The poles need to be planted on the ground. The depth of the working pit is difficult to ensure consistency, which affects the quality of the planted poles, which in turn affects the orientation and stability of the transmission line

Abstract

The invention discloses an electric pole pit groove digging device. The electric pole pit groove digging device comprises a frame, a rotating disc rotatably connected to the frame, a lifting mechanismconnected to the rotating disc, a digging knife assembly connected to the lifting mechanism for digging a pit groove, a counterweight assembly fixedly arranged at the rear portion of the frame and used for balancing the weight of the lifting mechanism, and a travelling mechanism arranged below the frame. According to the electric pole pit groove digging device, a pole carrying pit is excavated through mechanical automation, time and labor are saved, the construction efficiency is high, the depth of the pit groove is convenient to control, the stability consistence of carried poles is high, aposition sensor is used for aligning the front electric pole and the rear electric pole, the carried poles are guaranteed to be in a straight line, and the interval distance among the electric poles is measured and adjusted through an infrared distance sensor, so that the direction accuracy of a power transmission line is improved, and the running stability of the power transmission line is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power distribution line construction equipment, in particular to an electric pole pit excavation device. Background technique [0002] Electricity is an energy source powered by electrical energy. The primary energy in nature is converted into electricity through mechanical energy devices, and then the electricity is supplied to various users through power transmission, transformation and distribution. The transmission of electric energy, together with transformation, distribution and consumption, constitutes the overall function of the power system. Through power transmission, power plants and load centers that are far apart (up to thousands of kilometers) are connected, so that the development and utilization of electric energy transcends geographical restrictions. Compared with the transmission of other energy sources (such as coal transportation, oil transportation, etc.), power transmission has sma...
