Description
Technical Field
The invention belongs to the technical field of power grid line iron tower erection construction, and particularly relates to an overlong cross arm erection construction device.
Background
The erection of the iron tower of the power grid line is always the most important and difficult of the construction of the power grid line. At present, the iron tower assembly method of the power grid line mainly comprises two main types of integral assembly and disassembly assembly. Because the power grid line iron tower is generally large in size, the line iron tower is relatively frequently disassembled and assembled.
When a single-circuit ultrahigh voltage transmission line passes through a heavy ice area and a strong wind area, a wine glass type iron tower is often adopted, and the iron tower has a clear stress structure and high load bearing capacity. However, the cross arm is long in length and difficult to construct and hoist, the common suspension holding pole cannot be independently used, the herringbone holding pole is often used, the herringbone holding pole needs to be moved twice, construction is time-consuming and labor-consuming, and safety risk is high.
The Chinese utility model 'a multipurpose herringbone holding pole for the ultra-high voltage iron tower assembly' (publication number: CN207513297U) discloses a multipurpose herringbone holding pole for the ultra-high voltage iron tower assembly, relating to the field of the construction of the ultra-high voltage transmission line pole tower assembly. Traditional herringbone holding poles are single in function, and when the herringbone holding poles stand up, a base is unstable, and complicated braking measures need to be set. The utility model discloses a hold pole body, locate the tackle pulley group on holding pole body top by 2 pole types hold pole main parts and connect the herringbone that forms, hold the lower extreme of pole main part and pass through the articulated slab and hold the pole base articulated, 2 individual tops of holding the pole main part are passed through the connecting piece and are connected. The utility model discloses a what weigh on side is that promote base connection structure's fastness, through rotatable hinge structure, makes things convenient for the herringbone to hold the pole and realize the function of standing up as the suspension armful pole, through combining the tackle pulley group, the lifting by crane of the tower material of also being convenient for, through the length adjustment of armful pole main part to the assemblage and the tower material of adaptation co-altitude lift by crane, but it is not applicable to this application and holds the user demand of pole to the herringbone. The utility model discloses a pole structure is embraced to herringbone of multipurpose, but its side load is in the fixed of base, promotes base connection structure's fastness, and the bearing load ability of embracing the pole to the herringbone does not have too much to relate to.
The invention discloses a construction method for assembling a 1000kV linear iron tower by using double holding poles (publication number: CN 104594696B). The construction method for assembling the 1000kV linear iron tower by using the double holding poles is characterized in that the construction method for assembling the iron tower with a longer cross arm, a higher crank arm and a larger weight in a 1000kV ultrahigh voltage transmission line by using the double holding poles is used, and compared with the conventional construction method for hoisting a linear wine cup-shaped tower, the construction method is commonly used for assembling an inner-suspension outer-pull-wire single holding pole. This engineering uses two poles of embracing hoist and mount sharp goblet type tower greatly reduced construction safety risk, the instrument transportation of the mountain area topography of being convenient for, provides the safety guarantee for iron tower assemblage, has improved iron tower assemblage's efficiency of construction and economic benefits.
The Chinese invention patent 'an installation method of an ultra-high voltage transmission line wine cup type iron tower' (publication number: CN103924816B) discloses an installation method of an ultra-high voltage transmission line wine cup type iron tower, which comprises the following steps: preparation before construction; assembling the main holding pole and standing up the main holding pole; assembling and erecting tower legs on a tower footing; placing main material single pieces and tower pieces for assembling the tower body of the iron tower on the ground, lifting the main holding pole, and hoisting and assembling the tower body piece by piece; lifting the main holding pole to hoist the lower crank arm and the upper crank arm of the iron tower; hoisting the middle horizontal part; assembling the auxiliary holding pole on the ground, and hoisting the auxiliary holding pole; assembling the outer transverse flat on the ground and hoisting the outer transverse flat by using the auxiliary holding pole; installing a ground wire bracket and an iron tower accessory; carrying out maintenance and self-inspection to eliminate defects; and (5) dismantling the auxiliary holding pole and the main holding pole to finish construction. The invention solves the problem that the common holding pole is difficult to hoist and locate when the hoisting pieces such as the outer side cross arm and the like are far away from the center of the iron tower, reduces the probability of personnel and mechanical injury in the hoisting process of the outer side cross arm of the crank arm, improves the overall construction efficiency of the wine cup type iron tower, and ensures that the tower assembling construction quality is not influenced.
The two invention disclose the installation and construction method of the iron tower, the auxiliary holding pole is used during hoisting, but the length of the cross arm is long, the auxiliary holding pole needs to be moved for multiple times during actual installation, construction is time-consuming and labor-consuming, and safety risk is high.
