However, in urban residences in China, a large number of multi-storey residences in the eighties and ninety years of the 20 th century are built, and elevators are not configured under the limitation of the economic development level, the construction standard and the related building specifications at the time. With the aging problem of the population in China becoming more and more serious, the aging-adaptive reconstruction of the existing multi-storey residential building by additionally arranging the elevators is imperative. In recent years, a great deal of engineering improvement practices have been developed in Guangdong, Shanghai, Beijing, Fuzhou, Hangzhou and other places, and better social effects are achieved. Meanwhile, the improvement of old urban districts is promoted to be used as a civil engineering for improving the living conditions of the masses, and the addition of elevators in multi-storey houses of the old districts is encouraged.

At present, the existing multi-storey building is provided with the elevator in the related technology, and most of the existing multi-storey building adopts the construction mode of factory integral prefabrication and field integral hoisting. Although the field integral hoisting construction can be completed by using a general large crane, the distance between the existing buildings is limited due to the narrow road inside the field, and large transport vehicles and hoisting machinery are difficult to enter due to the interference of surrounding trees, street lamps and the like. Even if the movable type building block can be close to a construction site, the space of operation is limited, safety measures cannot be guaranteed, great potential safety hazards exist, and interference to residents is large. Therefore, a special small-sized hoisting device for hoisting construction of elevator engineering is urgently needed for the existing multi-story building.

Patent document No. CN107215749A discloses a construction device for lifting an elevator shaft structure, and proposes a construction method of sectional lifting on site by using factory integral prefabrication. Four upright posts are used as basic frames, and 4 motors synchronously drive a speed reducer and a winch to realize jacking operation. But the equipment installation is comparatively complicated, adopts the wire rope to promote the in-process because flexible tensile deformation of wire rope, leads to the pulling force to pass and synchronous control's degree of difficulty great.

Jacking is generally a construction method used for roof structures such as large-span and heavy-duty net racks. The method is characterized in that the grid structure is assembled on site, and then the jack is used for gradually jacking to a designed position, so that the jacking force is large and stable. The difference between the jacking method and the lifting method is that: the lifting equipment is different in position, wherein the lifting equipment is positioned below the structural fulcrum, and the lifting equipment is positioned above the structural fulcrum; the two have different action principles, the jacking equipment such as a jack adopted by the lifting device and the like can ascend along with the structure, and the position of the lifting equipment such as a winch adopted by the lifting device and the like is kept unchanged in the lifting process.
