Description

A steel corridor construction lifting device

Technical field

The utility model relates to the technical field of lifting devices, specifically a lifting device for steel corridor construction.

Background technique

Corridor was originally a form of ancient Chinese architecture, that is, a connecting structure between buildings. With the continuous improvement of the strength of modern building materials and the continuous progress of construction technology, steel corridors are constructed between originally independent buildings. It is already a relatively mature process. Steel corridors are generally welded and assembled on the ground, then lifted to the installation position through a lifting device, anchored through hydraulic equipment, and then welded.

Most of the common steel corridor construction lifting devices currently on the market are similar in structure. They are mainly cable hoisting equipment. Towers and other devices are installed on the top of the building. The cable is pulled by a winch. One end of the cable is connected to the steel corridor. Simultaneous lifting of multiple sets of equipment can make the level of steel corridors rise steadily. However, there are some functional deficiencies during actual use and there is room for improvement. For example, during the lifting process, there is a certain chance of high-rise wind between buildings. Blowing the corridor causes the cable to swing slightly. There are certain obstacles in the later docking and anchoring, and it does not have the function of stable lifting and anti-swaying. Secondly, after lifting to close to the installation position, due to the need for precise docking, the installation at the bottom is required. The personnel and the operators at the top conduct frequent interactive confirmations through dialogue devices. For the operators at the top, the lifting or descending distance is relatively abstract and does not have the function of intuitively reflecting the lifting distance; in addition, the current steel corridor is When lifting, since the pulling force points are mostly on both sides, the middle part of the corridor is subject to greater force, and frequent calculations and adjustments are required when setting the pulling points, which is more troublesome and does not have the function of balancing the force at the bottom of the lift.

Now, a new type of steel corridor construction lifting device is proposed to solve the above problems.
