Telescopic tripod for erecting wire rod

Abstract

The invention discloses a telescopic tripod for erecting wire rods, comprising three landing legs and three beams, wherein each landing leg is composed of a branch pipe and a fulcrum bar connected with the branch pipe in a drawing mode; the fulcrum bar is evenly provided with a plurality of B-shaped bi-concave grooves; the position near the connection part of the branch pipe and the fulcrum bar on the branch pipe is provided with two clamping and fastening mechanisms matched with the B-shaped bi-concave grooves; the landing legs and the beams are movably connected by a cardan shaft. The telescopic tripod for erecting wire rod of the invention sets the landing legs and the beams into a drawing telescopic structure, solving the problem that the existing tripod is not favourable for transporting and carrying; when the telescopic tripod is not used, the fulcrum bar on the upper part is withdrawn in the thicker branch pipe on the lower part; when used, the fulcrum bar on the upper part extends out to buckle two clamping and fastening mechanisms matched with the B-shaped bi-concave groove on the branch pipe to ensure extending connection reliability as well as improve the safety factors of the invention.

Description

technical field [0001] The invention belongs to the technical field of auxiliary tools for erecting utility poles by human power, in particular to a telescopic tripod for erecting utility poles. Background technique [0002] The tripod currently used must be used on a level ground when erecting the pole to ensure the stability of the tripod. After the tripod is erected, the hanging chain pole is used. The disadvantage is that it cannot be erected on slopes and mountains, because there are slopes and mountains. The vertical pole is limited by geographical conditions, the triangle is not stable enough, and the vertical pole has certain risks. Moreover, since the tripod is composed of three steel pipes with a height of about eight meters, special vehicles must be used for carrying and transportation, which is not conducive to transportation and carrying. . In addition, there are also some telescopic poles, such as photography brackets, fishing poles, etc., which are often not ...

AI Technical Summary

Problems solved by technology

[0002] The tripod currently used must be used on a level ground when erecting the pole to ensure the stability of the tripod. After the tripod is erected, the hanging chain pole is used. The disadvantage is that it cannot be erected on slopes and mountains, because there are slopes and mountains. The vertical pole is limited by geographical conditions, the triangle is not stable enough, and the vertical pole has certain risks. Moreover, since the tripod is composed of three steel pipes with a height of about eight meters, special vehicles must be used for carrying and transportation, which is not conducive to transportation and carrying.

In addition, there are also some telescopic poles, such as photography brackets, fishing poles, etc., which are often not fixed firmly after expansion. In some special cases, they cannot meet their requirements for strength and reliability, especially in the case of safe construction. , its safety is often more important
