Double horizontal arm grounding hold-pole

A double flat arms ground holding pole belongs to a lift device which is used in high tower establishment. A pole body 2 comprises a plurality of standard joints 4 which are orderly overlapped, and upper and lower adjacent standard joints 4 are fixedly connected via a bolt, and external of the pole body 2 is provided with a wall adhering frame 11 which is sleeved on the standard joint 4, and the wall adhering frame 11 is connected to an external fixture 6 via a flexible connecting mechanism 7 for assembly workpieces, and a hydraulic lifting mechanism 5 is arranged on periphery of a basal portion of the pole body 2. The standard joint 4 is introduced from the ground so as to realize self lifting of the holding pole. A soft adhering wall of the periphery of the holding pole is connected to an iron tower, therefore having convenient dismounting and large accommodation amplitude, and the double flat arms can be folded upward and then is self descended with the pole body 2 as a whole. A base is connected to anchor bolts which are arranged on the foundation, which can be repeatedly used; and the whole machine has high safety, convenient operation and dismounting and high construction efficiency, which is especially suitable for use in establishment and construction of towers with large height such as a large-span tower or an ultra high pressure tower and also for use in hoisting and constructing operation of high building.
