Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] Such as figure 1 As shown, the embodiment of the present invention includes a first operating long pole 1, a second operating long pole having an upper section pole 23 and a lower section pole 24, a first earth digging blade 11, a second earth excavating blade 21, and a pole located at the first operating pole. 1 and the connecting frame between the second operating rod. Wherein the first operating rod 1 is also a segmented structure, which is convenient for storage and transportation, and the segments can be connected by threads, which is relatively simple.
[0019] Specifically, both the first long operating rod 1 and the second long operating rod are used for handheld operation. The first earth digging shovel 11 is connected to the lower end of the first operating long pole 1, and is used for excavating electric pole pits....

The invention provides a special tool for excavating an electric pole pit. The tool comprises a first long operation rod for hand holding operation, a first earth cutting spade connected to the lower end of the first long operation rod and used for excavating the electric pole pit, a second long operation rod for hand holding operation, a second earth cutting spade connected to the lower end of the second long operation rod and used for excavating the electric pole pit, and a connection frame. The first earth cutting spade is opposite to the second earth cutting spade. The connection frame is hinged to the connection position of the first long operation rod and the first earth cutting spade and is hinged to the connection position of the second long operation rod and the second earth cutting spade so that the first earth cutting spade can be close to the second earth cutting spade to take out broken soil in the electric pole pit. According to the special tool for excavating electric pole pit, the long operation rods stretch in to the electric pole pit, the excavating amount of soil and stones is reduced greatly, the amount of the backfilled soil and stones is also small after an electric pole is vertically arranged in the pit, and stability of the electrode rod is improved obviously.
Description
technical field [0001] The invention relates to a construction tool for electric power stringing engineering, in particular, the invention particularly relates to a special tool for digging holes for electric poles. Background technique [0002] In the construction of electric power engineering, the work of erecting wires on poles is often included, and pole pits must be excavated for erecting poles. Digging pole pits must have a certain depth. At present, shovels are mostly used to dig pits, and shovels cannot directly dig deep pits, so a large area of earthwork must be dug to ensure the depth. It takes 1 hour and 15 minutes, which is laborious and time-consuming, which directly affects the speed of the project; moreover, after the poles are erected, the earthwork for backfilling will be large and not as firm as the original soil layer, which will bring hidden dangers to the stability of the poles . Contents of the invention [0003] The purpose of the present inventi...
