Steel tube mast standing device

Abstract

The invention relates to a steel tube mast standing device which comprises a main clamp, a pair of steel shoes and limit devices, wherein the main clamp can be fixed on a cement base, the steel shoes are used for fixing a base of a steel tube mast, and the limit device is used for decreasing the component force angle of a dynamic rope for supporting during the initial standing of the steel tube mast, limiting the steel tube mast after standing and keeping a mast body to be vertical basically, the front end of the clamp is flexibly connected with the steel shoes which can overturn on the main clamp, two sides of the main clamp are provided with the limit devices, and the front end of each limit device is provided with a pair of positioning levers. The invention has the advantages of light weight, simple and reliable operation, labor saving and work saving; compared with a previous method that three sticks are lapped together to stand the steel tube mast, the invention can save working period by more than 50 % as well as save labor by more than 50 %, and thus working efficiency is increased by more than 4 times; and even more working efficiency can be increased in severe environment.

Description

technical field [0001] The invention relates to a steel pipe mast erector. Background technique [0002] The existing steel pipe type feeder rod stands on 4 anchor bolts above the cement base. When the pole is erected, the bottom of the pole is suspended. After the pole is lifted, the flange plate of the bottom of the pole drifts and touches on the four anchor bolts. Some utility masts tend to come with heavy loads. For example, there is a feeder frame on the top of the medium-wave feeder pole of a radio station, which is top-heavy. In conventional construction, free-hand poles and auxiliary cable control methods are often used, which is very prone to inverted poles and is unsafe. [0003] In recent years, "three-wooden building", "two-wooden building" or crane poles have been used, but they are often limited by the construction site and cannot be constructed. And the "three-wood building" is heavy, the labor intensity of self disassembly and displacement is high, the wo...

Problems solved by technology

In addition, due to the needs of the design and construction period, the pole base is more than 80 cm above the ground when the pole is erected, which is even more difficult to construct. The safety guarantee of pole construction is a difficult problem
