Description

Spliced electric pole Technical Field The utility model relates to the technical field of power equipment, in particular to a spliced electric pole. Background The distribution overhead line is a key infrastructure for conveying electric energy from a transformer substation to a terminal user in an electric power system, the electric pole is used as a core supporting member of the system, and mainly plays the roles of lifting wires and ensuring that a charged part and a surrounding environment keep a safe insulation distance, and is an indispensable part for ensuring safe and stable operation of a power grid. In practical engineering application, the length of a single electric pole is usually controlled within 12 meters under transportation conditions (such as road height limit, vehicle load, turning radius and the like), however, in complex terrain or special crossing scenes, the total height of the electric pole often needs to reach 15 meters or more, and in order to solve the contradiction, the sectional electric pole design is gradually adopted in engineering, and a plurality of sections of electric poles are connected into a whole through pole tower joints. At present, the tower joint mainly adopts three forms of plug-in type, flange type and sleeve joint type, wherein the plug-in type joint is connected through nesting and matching of an inner sleeve and an outer sleeve, although the structure is simple, obvious diameter mutation can be formed at the joint, the flange type joint adopts a disc-shaped connecting structure fastened by bolts, the joint part is outwards protruded to form an annular bulge, and the sleeve joint type joint is connected in a transitional mode through a conical sleeve, so that discontinuous change of the outer diameter of the shaft is caused. The joint forms can realize the mechanical connection function, but all have the commonality problem of structural appearance mutation, so that the defects of rod climbing operation obstacle, safety risk improvement, operation and maintenance cost increase and the like are caused, the diameter change at the joint or the convex structure breaks the continuity and consistency of the surface of the electric rod, physical obstacle on a climbing path is formed, operators need to climb the position by means of additional tools or change climbing posture to cross the joint part, the operation efficiency is reduced, safety accidents such as high falling are easier to be caused, meanwhile, the applicability of conventional rod climbing tools such as climbers and safety belts is reduced due to the fact that the surface of a non-standardized rod body is provided with special auxiliary equipment. Disclosure of utility model The utility model aims to provide a spliced pole. The spliced pole is formed by splicing a plurality of pipe bodies end to end, any two adjacent pipe bodies are connected through a connecting rod, two ends of each connecting rod extend into the corresponding two adjacent pipe bodies respectively and are assembled coaxially with the pipe bodies in a fitting mode, two groups of threaded holes are formed in each connecting rod, a group of first through holes are formed in each adjacent pipe body, the two groups of first through holes in the adjacent pipe bodies are in one-to-one correspondence with the two groups of threaded holes in the corresponding connecting rod, each first through hole corresponds to a bolt, the bolts penetrate through the first through holes and extend into the corresponding threaded holes to be in threaded fit with the threaded holes, the adjacent pipe bodies are separated, and gaps between the adjacent pipe bodies form anti-compression joints. Further, the pipe body is a taper pipe, and the diameters of the end parts connected with the adjacent pipe bodies are consistent. The electric pole is usually a conical pipe with a large lower diameter and a small upper diameter, and the pipe body of the conical pipe can be used for splicing the conical electric pole. The pole base with large lower diameter and small upper diameter is more stable and is more firmly installed. Further, the connecting rod is a pipe body. The connecting rod can be a solid rod or a hollow pipe body. Compared with a solid rod, the novel steel rod is light in weight, convenient to carry and more material-saving. Further, a second through hole is formed in the wall body of the connecting rod, a nut is fixedly mounted on the inner wall of the connecting rod, the nut and the second through hole are coaxially arranged, and an inner hole of the nut forms the threaded hole. The threaded hole can be directly formed in the connecting rod, and the nut can be fixed on the connecting rod, so that the inner hole of the nut forms the threaded hole. Compared with the former, the latter is convenient to draw materials, is simpler to set up, especially under the condition that the wall thickness of the connecting rod of body is thinner, compare the connecti
