Problems solved by technology

The disadvantages of the above two methods are: the cost is high, and the span of the original line is changed, thereby changing the stress state of the tower and the adjacent iron tower; during the construction process, the transmission line of the iron tower must stop power transmission and cause economic losses. Therefore, the above two methods The effect of the method is not ideal in practical application, and the above method is not applicable when the land beside the original iron tower cannot be acquired or the line span cannot be changed due to surrounding conditions.

Embodiment Construction

[0028] refer to figure 1 , the self-climbing rod jacking device of this embodiment includes four fully threaded jacking rods 1, and the fixing device on each jacking rod 1 is a lock nut 2, and the lock nut 2 fixes the support base 3 on the On the horizontal plane between the jacking screws 1, a jack 4 is placed on the supporting base 3, and the top of the jack 4 is placed at the bottom of the supporting surface 5 of the object to be lifted.

[0029] refer to figure 2 , image 3 , applying the device of the present invention to the jacking of high-voltage iron towers, Figure 4 yes image 3 A-A cut-away enlarged view. This high-voltage line iron tower 12 has four load-bearing legs, two of which are shown in the figure, and there is an iron tower column foot plate at the bottom of each leg, that is, the supporting surface 5 of the object to be lifted, and the iron tower 12 will be lifted up. It is necessary to install the self-climbing type pole jacking device of the prese...

Abstract

A self-climbing lifting apparatus for lifting up the iron tower of high-voltage transmission lines is composed of at least two lifting screw rod, the fixer on each lifting screw rod of fixing the gradually lifted supporting plate for said iron tower and the supporting base to the lifting screw rod, and jack on the supporting base for lifting said supporting plate. Its lifting method features thatinstalling said apparatus to each leg of iron tower, and operating the jacks to lift up the iron tower gradually.

Description

technical field [0001] The invention relates to a jacking device and a jacking method for raising a building, in particular to a jacking device and a method for raising a high-voltage line iron tower. Background technique [0002] At present, there are many high-voltage line towers in the power sector due to foundation sinking or changes in the surrounding environment, resulting in high-voltage line ground clearance heights that do not meet the requirements of current relevant regulations, bringing hidden dangers to high-voltage line equipment, vehicles, and pedestrians. At present, there are generally two solutions: one is to requisition land next to the tower to make the tower foundation, remove the high-voltage lines on the original tower, and then use a crane to lift the upper part of the original tower foundation to the new foundation, and finally install it on the new tower. Install high-voltage lines; the other is to requisition land next to the tower to build a new t...
