Problems solved by technology
Based on the above two analyses, the initial support structure at this time is in an unstable state, and there are great potential safety hazards during construction.
During construction, because two 5-ton chain hoists are fixed under the grille, it is difficult to move laterally, which makes the hoisting and installation of steel pipe columns extremely difficult, requiring multiple workers to complete the work, and the efficiency is low

The invention discloses a device for hoisting and installing a steel pipe column in a hoisting frame hole, comprising a lower positioning installation device, an upper hoisting device and a steel pipe column, the lower positioning installation device includes a positioning steel plate, and the upper hoisting device includes a sliding hoisting device and a steel pipe column. The triangular bracket, the sliding lifting equipment includes a walking device and a lifting equipment. At the same time, the invention discloses a method for hoisting and installing steel pipe columns in the hole of the lifting frame. The invention uses steel pipes as the skeleton and industrial steel as the lifting beam The amount cooperates with the walking motor and the chain hoist to form a light hoisting equipment that can be moved, the height is only lower than the height of the guide hole, and the hoisting equipment can move left and right, and the bracket has a stable bearing capacity. It is a component with small size and light weight, which can be easily combined and installed in a small space, and can be hoisted and installed quickly. During the construction process, the stable structure of the initial support will not be damaged, and the construction efficiency is high.
Description
technical field [0001] The invention relates to a technology for hoisting and installing a steel pipe column in a hole, and particularly designs a device and method for hoisting and installing a steel pipe column in a hole of a hoisting frame. Background technique [0002] With the rise of the construction technology of shallow burial and underground excavation in my country's subway construction, more and more subway stations are constructed using the hole pile method. After the bottom beam is completed, holes will be opened in the upper pilot tunnel at the position of the downward pilot tunnel, and the steel pipe column, the main load-bearing component of the subway station, will be transported, hoisted and installed in the upper pilot tunnel after the piles are dug through. A single steel pipe column weighs about 8 tons and is about 9 meters long. The upper guide tunnel is generally 5-6 meters wide and 4-4.5 meters high. The space in the cave is limited. Even if the steel ...
