Description

Auxiliary pulling device for angle iron pile

Technical Field

The utility model relates to an angle iron pile plays and pulls out technical field, in particular to angle iron pile assists pulling out device.

Background

At present, temporary grounding electrodes are required to be arranged frequently in the test process of grounding devices such as large buildings or transformer substations and the like. When the work place is transferred or the operation is finished, the grounding electrode driven into the ground needs to be pulled out, and the common grounding pile adopts an angle iron pile or a round pipe pile, so that the operation is not easy during pulling out, and time and labor are wasted.

Similarly, in the construction process of the power transmission line, the temporary stay wire is often used for balancing the stress condition, the temporary stay wire is mainly used for balancing the tension of an overhead line after the unilateral hanging of a wire of a lead, so that the tension pole is kept balanced and stable in the wire tightening process, and the broken pole accident can occur if the temporary stay wire is not tied in the wire tightening process, so that the temporary stay wire can be erected in multiple occasions such as replacing the corrosion stay wire, the tower overhead line, the tower assembly, the rush-repair tower assembly and the like, and the safety and reliability of operation are ensured.

The temporary stay wire of the site operation is mostly fixed by adopting an angle iron pile, namely, the pile anchor is angle iron, the structure is simple, and the carrying is convenient. After the interim draw off mechanism finishes using, the fixed angle iron stake of acting as go-between need be retrieved, however the angle iron stake most buries ground, the angle iron stake will be extracted, generally the operating personnel left and right sides wheel sledge hammer strikes the angle iron stake, extract after making the angle iron stake become flexible, waste time and energy, intensity of labour is big, or adopt the structure of reprocess angle iron stake and auxiliary frame calabash to lift by crane, though this kind of angle iron stake can realize extracting the function, but every angle iron stake changes the structure trouble and with high costs, auxiliary frame has increased intensity of labour again, practicality is not high to field operation personnel. Although utility model patent application publication No. CN203871758U, the name is one kind from angle iron pile of taking spiral pulling device adopts and sets up spiral pulling device at the angle iron pile internal fixation, realizes pulling out of angle iron pile through the hob. The mode is really more convenient than the traditional operation, but the structure is complex, each pile needs to be provided with one drawing device independently, thus the cost is high, the weight of the angle iron pile is increased, and the transportation is inconvenient.
